FORWARD-LOOKING STATEMENTS

In addition to historical information,  this Annual Report on Form 10-K contains
forward-looking  statements  about TriCo Bancshares (the "Company") for which it
claims the  protection  of the safe harbor  provisions  contained in the Private
Securities Litigation Reform Act of 1995. These  forward-looking  statements are
based on  Management's  current  knowledge  and belief and  include  information
concerning  the Company's  possible or assumed  future  financial  condition and
results  of  operations.  When you see any of the words  "believes",  "expects",
"anticipates",  "estimates",  or similar  expressions,  these generally indicate
that we are making  forward-looking  statements.  A number of  factors,  some of
which are beyond the Company's ability to predict or control, could cause future
results to differ  materially  from those  contemplated.  These factors  include
those listed at Item 1A Risk Factors, in this report.










                                     PART I

ITEM 1. BUSINESS

Information About TriCo Bancshares' Business

TriCo  Bancshares  (the "Company" or "TriCo") was  incorporated in California on
October 13, 1981. It was organized at the direction of the board of directors of
Tri  Counties  Bank (the  "Bank")  for the  purpose  of  forming a bank  holding
company.  On September 7, 1982, the shareholders of Tri Counties Bank became the
shareholders of TriCo and Tri Counties Bank became a wholly owned  subsidiary of
TriCo.  At that  time,  TriCo  became  a bank  holding  company  subject  to the
supervision  of the Board of Governors  of the Federal  Reserve  System  ("FRB")
under the Bank  Holding  Company Act of 1956,  as  amended.  Tri  Counties  Bank
remains  subject to the  supervision of the  California  Department of Financial
Institutions and the Federal Deposit Insurance Corporation ("FDIC"). On July 31,
2003, the Company formed a subsidiary  business trust, TriCo Capital Trust I, to
issue  trust  preferred  securities.  On June 22,  2004,  the  Company  formed a
subsidiary  business  trust,  TriCo Capital  Trust II, to issue trust  preferred
securities.  See Note 8 in the financial statements at Item 8 of this report for
a discussion  about the Company's  issuance of trust preferred  securities.  Tri
Counties  Bank,  TriCo  Capital Trust I and TriCo Capital Trust II currently are
the  only  subsidiaries  of  TriCo  and  TriCo is not  conducting  any  business
operations  independent  of Tri Counties  Bank,  TriCo Capital Trust I and TriCo
Capital Trust II.

For  financial  reporting  purposes,  the  financial  statements of the Bank are
consolidated into the financial statements of the Company. Historically,  issuer
trusts,  such as TriCo  Capital  Trust I and TriCo Capital Trust II, that issued
trust preferred  securities have been consolidated by their parent companies and
trust  preferred  securities  have been  treated as eligible  for Tier 1 capital
treatment by bank holding companies under FRB rules and regulations  relating to
minority interests in equity accounts of consolidated subsidiaries. Applying the
provisions of the Financial  Accounting  Standards Board Revised  Interpretation
No. 46 (FIN 46R), the Company is no longer  permitted to consolidate such issuer
trusts  beginning on December 31, 2003.  Although the FRB has stated in its July
2, 2003  Supervisory  Letter that trust preferred  securities will be treated as
Tier 1 capital until notice is given to the  contrary,  the  Supervisory  Letter
also  indicates  that the FRB will  review the  regulatory  implications  of any
accounting  treatment  changes and will provide further guidance if necessary or
warranted.

On April 4, 2003,  TriCo acquired North State National Bank, a national  banking
organization  located in Chico,  California  ("North  State"),  by the merger of
North State into the Bank. At the time of the acquisition, North State had total
assets of $140  million,  investment  securities  of $41  million,  loans of $76
million,  and deposits of $126 million.  The acquisition was accounted for using
the purchase  method of  accounting.  The amount of goodwill  recorded as of the
merger date,  which  represented the excess of the total purchase price over the
estimated fair value of net assets acquired,  was  approximately  $15.5 million.
The Company recorded a core deposit  intangible,  which represents the excess of
the  fair  value  of  North  State's  deposits  over  their  book  value  on the
acquisition date, of approximately $3.4 million. This core deposit intangible is
being amortized over a seven-year  average life. TriCo paid $13,090,057 in cash,
issued  723,512  shares of TriCo common  stock,  and issued  options to purchase
79,587  shares of TriCo common stock at an average  exercise  price of $6.22 per
share in exchange for all of the 1,234,375 common shares and options to purchase
79,937 common shares of North State outstanding as of April 4, 2003.

Business of Tri Counties Bank

Tri Counties Bank was incorporated as a California  banking  corporation on June
26, 1974, and received its certificate of authority to begin banking  operations
on March 11, 1975. Tri Counties Bank engages in the general  commercial  banking
business in the California counties of Butte,  Contra Costa, Del Norte,  Fresno,
Glenn,  Kern,  Lake,  Lassen,   Madera,   Mendocino,   Merced,  Nevada,  Placer,
Sacramento, Shasta, Siskiyou, Stanislaus, Sutter, Tehama, Tulare, Yolo and Yuba.
Tri  Counties  Bank  currently  operates  from 32  traditional  branches  and 17
in-store branches.

General Banking Services

The Bank conducts a commercial  banking  business  including  accepting  demand,
savings and time  deposits  and making  commercial,  real  estate,  and consumer
loans. It also offers  installment note collection,  issues cashier's checks and
money orders,  sells travelers  checks and provides safe deposit boxes and other
customary  banking  services.  Brokerage  services  are  provided  at the Bank's
offices by the Bank's association with Raymond James Financial  Services,  Inc.,
an independent financial services provider and broker-dealer.  The Bank does not
offer trust services or international banking services.

The Bank has  emphasized  retail  banking  since it  opened.  Most of the Bank's
customers are retail  customers and small to medium-sized  businesses.  The Bank
emphasizes serving the needs of local businesses,  farmers and ranchers, retired
individuals and wage earners.  The majority of the Bank's loans are direct loans
made to individuals and businesses in northern and central  California where its
branches are located.  At December  31, 2005,  the total of the Bank's  consumer
installment loans net of deferred fees outstanding was $508,233,000 (36.7%), the
total of commercial loans outstanding was $143,175,000 (10.3%), and the total of
real estate loans including  construction loans of $110,116,000 was $733,627,000
(53.0%). The Bank takes real estate, listed and unlisted securities, savings and
time deposits, automobiles, machinery, equipment, inventory, accounts receivable
and notes receivable secured by property as collateral for loans.

Most of the Bank's deposits are attracted from individuals and  business-related
sources. No single person or group of persons provides a material portion of the
Bank's deposits,  the loss of any one or more of which,  would have a materially
adverse  effect on the  business of the Bank,  nor is a material  portion of the
Bank's  loans  concentrated  within  a  single  industry  or  group  of  related
industries.

In order to attract  loan and deposit  business  from  individuals  and small to
medium-sized  businesses,  branches of the Bank set lobby  hours to  accommodate
local demands.  In general,  lobby hours are from 9:00 a.m. to 5:00 p.m.  Monday
through  Thursday,  and from 9:00 a.m. to 6:00 p.m. on Friday.  Certain branches
with less activity open later and close earlier.  Some Bank offices also utilize
drive-up  facilities  operating  from 9:00 a.m.  to 7:00  p.m.  The  supermarket
branches  are open from 9:00 a.m.  to 7:00 p.m.  with some open  until 8:00 p.m.
Monday through Saturday and 11:00 a.m. to 5:00 p.m. on Sunday.

The Bank offers  24-hour  ATMs at almost all branch  locations.  The 56 ATMs are
linked to several  national and regional  networks  such as CIRRUS and STAR.  In
addition, banking by telephone on a 24-hour toll-free number is available to all
customers.  This service allows a customer to obtain  account  balances and most
recent transactions,  transfer moneys between accounts,  make loan payments, and
obtain interest rate information.

In  February  1998,  the Bank became the first bank in the  Northern  Sacramento
Valley to offer banking services on the Internet.  This banking service provides
customers one more tool for access to their accounts.

Other Activities

The  Bank may in the  future  engage  in other  businesses  either  directly  or
indirectly  through  subsidiaries  acquired  or  formed by the Bank  subject  to
regulatory constraints. See "Regulation and Supervision."

                                      -3-



Employees

At December 31, 2005,  the Company and the Bank employed 670 persons,  including
five executive officers.  Full time equivalent  employees were 604. No employees
of the Company or the Bank are presently represented by a union or covered under
a  collective  bargaining  agreement.  Management  believes  that  its  employee
relations are excellent.

Competition

The banking business in California generally,  and in the Bank's primary service
area of Northern and Central California specifically, is highly competitive with
respect to both loans and deposits. It is dominated by a relatively small number
of  national  and  regional  banks  with  many  offices  operating  over  a wide
geographic  area.  Among the  advantages  such major banks have over the Bank is
their  ability to finance wide  ranging  advertising  campaigns  and to allocate
their investment  assets to regions of high yield and demand. By virtue of their
greater total capitalization such institutions have substantially higher lending
limits than does the Bank.

In addition to competing  with savings  institutions,  commercial  banks compete
with other  financial  markets for funds as a result of the  deregulation of the
financial services industry.  Yields on corporate and government debt securities
and other commercial paper may be higher than on deposits,  and therefore affect
the ability of commercial  banks to attract and hold deposits.  Commercial banks
also compete for available funds with money market instruments and mutual funds.
During past periods of high  interest  rates,  money market funds have  provided
substantial  competition to banks for deposits and they may continue to do so in
the future.  Mutual  funds are also a major  source of  competition  for savings
dollars.

The Bank relies substantially on local promotional  activity,  personal contacts
by  its  officers,  directors,  employees  and  shareholders,   extended  hours,
personalized  service  and its  reputation  in the  communities  it  services to
compete effectively.

Regulation and Supervision

As a consequence of the extensive regulation of commercial banking activities in
California and the United  States,  the business of the Company and the Bank are
particularly  susceptible  to  changes  in state  and  federal  legislation  and
regulations, which may have the effect of increasing the cost of doing business,
limiting  permissible  activities  or  increasing  competition.  Following  is a
summary of some of the laws and  regulations  which  effect the  business.  This
summary  should  be read  with  the  management's  discussion  and  analysis  of
financial condition and results of operations included at Item 7 of this report.

As a registered  bank holding company under the Bank Holding Company Act of 1956
(the "BHC Act"), the Company is subject to the regulation and supervision of the
FRB.  The BHC Act  requires the Company to file reports with the FRB and provide
additional  information  requested  by the FRB.  The  Company  must  receive 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 Company would own or control
more than 5 percent of the voting shares of such bank.

The Company and any subsidiaries it may acquire or organize will be deemed to be
affiliates  of the Bank within the Federal  Reserve  Act.  That Act  establishes
certain  restrictions,  which  limit the extent to which the Bank can supply its
funds to the  Company  and other  affiliates.  The  Company  is also  subject to
restrictions  on the  underwriting  and the  public  sale  and  distribution  of
securities.  It is prohibited  from engaging in certain tie-in  arrangements  in
connection  with  any  extension  of  credit,  sale or  lease  of  property,  or
furnishing of services.

The Company is generally  prohibited  from  engaging in, or acquiring  direct or
indirect  control of any company engaged in non-banking  activities,  unless the
FRB by order or regulation has found such activities to be so closely related to
banking or managing or  controlling  banks as to be a proper  incident  thereto.
Notwithstanding this prohibition, under the Financial Services Modernization Act
of 1999, the Company may engage in any activity,  and may acquire and retain the
shares of any company  engaged in any  activity,  that the FRB, in  coordination
with the Secretary of the Treasury,  determines  (by  regulation or order) to be
financial in nature or incidental  to such  financial  activities.  Furthermore,
such law dictates  several  activities  that are  considered  to be financial in
nature, and therefore are not subject to FRB approval.

                                      -4-



The Bank, as a state-chartered  bank, is subject to regulation,  supervision and
regular  examination  by the  California  Department  of Financial  Institutions
("DFI")  and is  also  subject  to the  regulations  of the  FDIC.  Federal  and
California  statutes  and  regulations  relate  to many  aspects  of the  Bank's
operations,  some of which are described below. The DFI regulates the number and
location of branch  offices and may permit a bank to maintain  branches  only to
the extent  allowable under state law for state banks.  California law presently
permits a bank to locate a branch in any locality in California.

Gramm-Leach-Bliley Act

The  Gramm-Leach-Bliley Act 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 FRB and the  Securities and Exchange
Commission  ("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 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  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 Community Reinvestment Act examinations of community banks.

The  Company  has  undertaken  efforts  to  comply  with all  provisions  of the
Gramm-Leach-Bliley   Act  and  all  implementing   regulations,   including  the
development   of   appropriate   policies   and   procedures   to   meet   their
responsibilities  in connection  with the privacy  provisions of Title V of that
act.

Safety and Soundness Standards

The Federal  Deposit  Insurance  Corporation  Improvement Act of 1991 ("FDICIA")
implemented  certain  specific  restrictions  on  transactions  and required the
regulators  to adopt  overall  safety and  soundness  standards  for  depository
institutions  related to internal control,  loan underwriting and documentation,
and asset growth.  Among other things,  FDICIA limits the interest rates paid on
deposits by undercapitalized  institutions, the use of brokered deposits and the
aggregate  extension  of  credit by a  depository  institution  to an  executive
officer,  director,  principal  stockholder  or related  interest,  and  reduces
deposit insurance coverage for deposits offered by undercapitalized institutions
for deposits by certain employee benefits accounts.



                                      -5-



The FDICIA  added a new Section 39 to the Federal  Deposit  Insurance  Act which
required the agencies to establish  safety and  soundness  standards for insured
financial institutions covering:

      -   internal controls, information systems and internal audit systems;
      -   loan documentation;
      -   credit underwriting;
      -   interest rate exposure;
      -   asset growth;
      -   compensation, fees and benefits;
      -   asset quality, earnings and stock valuation; and
      -   excessive compensation for executive officers,  directors or principal
          shareholders which could lead to material financial loss.

If an  agency  determines  that  an  institution  fails  to  meet  any  standard
established by the guidelines,  the agency may require the financial institution
to submit to the  agency  an  acceptable  plan to  achieve  compliance  with the
standard.  If the  agency  requires  submission  of a  compliance  plan  and the
institution  fails to  timely  submit  an  acceptable  plan or to  implement  an
accepted  plan,  the  agency  must  require  the   institution  to  correct  the
deficiency.  An  institution  must file a  compliance  plan  within 30 days of a
request to do so from the institution's  primary federal  regulatory agency. The
agencies may elect to initiate  enforcement  action in certain cases rather than
rely on an existing plan  particularly  where failure to meet one or more of the
standards could threaten the safe and sound operation of the institution.

Restrictions on Dividends and Other Distributions

The power of the board of directors of an insured depository  institution,  such
as the Bank,  to declare a cash dividend or other  distribution  with respect to
capital is subject to  statutory  and  regulatory  restrictions  which limit the
amount available for such  distribution  depending upon the earnings,  financial
condition  and  cash  needs  of the  institution,  as well as  general  business
conditions.   FDICIA  prohibits  insured  depository  institutions  from  paying
management fees to any controlling  persons or, with certain limited exceptions,
making capital distributions,  including dividends,  if, after such transaction,
the institution would be  undercapitalized.  Additionally,  under FDICIA, a bank
may not make any capital  distribution,  including the payment of dividends,  if
after   making   such   distribution   the   bank   would   be  in  any  of  the
"under-capitalized"   categories  under  the  FDIC's  Prompt  Corrective  Action
regulations.

Under  the  Financial  Institution's  Supervisory  Act,  the  FDIC  also has the
authority to prohibit a bank from engaging in business  practices  that the FDIC
considers to be unsafe or unsound. It is possible,  depending upon the financial
condition  of a bank and  other  factors  that the FDIC  could  assert  that the
payment of dividends or other  payments in some  circumstances  might be such an
unsafe or unsound practice and thereby prohibit such payment.

Under  California  law,  dividends  and other  distributions  by the Company are
subject to  declaration  by the board of directors at its  discretion out of net
assets.  Dividends  cannot be declared and paid when such payment would make the
Company insolvent. FRB policy prohibits a bank holding company from declaring or
paying a cash  dividend  which  would  impose  undue  pressure on the capital of
subsidiary   banks  or  would  be  funded  only  through   borrowings  or  other
arrangements  that  might  adversely  affect  the  holding  company's  financial
position.  The policy  further  declares that a bank holding  company should not
continue its existing rate of cash  dividends on its common stock unless its net
income is  sufficient to fully fund each  dividend and its  prospective  rate of
earnings  retention appears consistent with its capital needs, asset quality and
overall  financial  condition.  Other FRB  policies  forbid the  payment by bank
subsidiaries  to  their  parent   companies  of  management   fees,   which  are
unreasonable  in amount or exceed a fair market value of the  services  rendered
(or, if no market exists, actual costs plus a reasonable profit).

In  addition,  the FRB has  authority to prohibit  banks that it regulates  from
engaging  in  practices,  which in the opinion of the FRB are unsafe or unsound.
Such  practices may include the payment of dividends  under some  circumstances.
Moreover,  the payment of dividends may be  inconsistent  with capital  adequacy
guidelines.  The Company may be subject to  assessment to restore the capital of
the Bank should it become impaired.

Consumer Protection Laws and Regulations

The bank regulatory  agencies are focusing greater  attention on compliance with
consumer  protection laws and their  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. The
Company is subject to many federal consumer  protection statues and regulations,
some of which are discussed below.

The  Community  Reinvestment  Act of  1977  is  intended  to  encourage  insured
depository  institutions,  while operating safely and soundly,  to help meet the
credit needs of their  communities.  This act  specifically  directs the federal
regulatory  agencies 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 practices. This act 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  Community  Reinvestment  Act  assessment  factors in order to provide a
rating  to  the  financial  institution.  The  ratings  range  from  a  high  of
"outstanding" to a low of "substantial noncompliance."

The Equal Credit  Opportunity  Act  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 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 such  act,  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 payments and
the payment schedule, among other things.

The Fair Housing 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 this Act,  including some that are not
specifically  mentioned in the Act itself. The Home Mortgage Disclosure Act grew
out of public concern over credit shortages in certain urban  neighborhoods  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.  This act 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.

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

Penalties  under the above  laws may  include  fines,  reimbursements  and other
penalties. Due to heightened regulatory concern related to compliance with these
acts generally, the Company may incur additional compliance costs or be required
to expend additional funds for investments in their local community.

                                      -7-



USA Patriot Act of 2001

The USA Patriot Act was enacted in 2001 to combat money laundering and terrorist
financing.   The  impact  of  the  Patriot  Act  on  financial  institutions  is
significant  and wide  ranging.  The Patriot Act  contains  sweeping  anti-money
laundering and financial  transparency  laws and requires  various  regulations,
including:

      -   due diligence requirements for financial institutions that administer,
          maintain,  or manage private bank accounts or  correspondent  accounts
          for non-U.S. persons,
      -   standards for verifying customer identification at account opening,
      -   rules to promote cooperation among financial institutions, regulators,
          and law  enforcement  entities  to  assist  in the  identification  of
          parties that may be involved in terrorism or money laundering,
      -   reports  to be filed by  non-financial  trades and  business  with the
          Treasury   Department's   Financial  Crimes  Enforcement  Network  for
          transactions exceeding $10,000, and
      -   the filing of suspicious  activities reports by securities brokers and
          dealers if they  believe a customer  may be  violating  U.S.  laws and
          regulations.

Capital Requirements

Federal regulation imposes upon all financial  institutions a variable system of
risk-based capital guidelines designed to make capital requirements sensitive to
differences in risk profiles among banking  organizations,  to take into account
off-balance sheet exposures and to promote  uniformity in the definition of bank
capital uniform nationally.

The Bank and the Company are subject to the minimum capital  requirements of the
FDIC and the FRB, respectively. As a result of these requirements, the growth in
assets is  limited  by the  amount of its  capital  accounts  as  defined by the
respective  regulatory  agency.  Capital  requirements  may  have an  effect  on
profitability  and the payment of  dividends on the common stock of the Bank and
the Company. If an entity is unable to increase its assets without violating the
minimum  capital  requirements  or is forced to reduce  assets,  its  ability to
generate earnings would be reduced.

The FRB, and the FDIC have  adopted  guidelines  utilizing a risk-based  capital
structure. Qualifying capital is divided into two tiers. Tier 1 capital consists
generally of common stockholders'  equity,  qualifying  noncumulative  perpetual
preferred stock,  qualifying  cumulative perpetual preferred stock (up to 25% of
total  Tier 1  capital)  and  minority  interests  in  the  equity  accounts  of
consolidated  subsidiaries,  less goodwill and certain other intangible  assets.
Tier 2 capital  consists of, among other  things,  allowance  for loan and lease
losses up to 1.25% of weighted risk assets,  perpetual  preferred stock,  hybrid
capital  instruments,  perpetual debt,  mandatory  convertible  debt securities,
subordinated  debt  and  intermediate-term   preferred  stock.  Tier  2  capital
qualifies  as part of total  capital  up to a maximum of 100% of Tier 1 capital.
Amounts  in excess of these  limits may be issued  but are not  included  in the
calculation  of  risk-based  capital  ratios.  Under  these  risk-based  capital
guidelines,  the Bank and the Company are required to maintain  capital equal to
at  least 8% of its  assets,  of which at least 4% must be in the form of Tier 1
capital.

The  guidelines  also  require  the  Company  and the Bank to maintain a minimum
leverage ratio of 4% of Tier 1 capital to total assets (the  "leverage  ratio").
The leverage ratio is determined by dividing an institution's  Tier 1 capital by
its quarterly  average total assets,  less goodwill and certain other intangible
assets.  The  leverage  ratio  constitutes  a minimum  requirement  for the most
well-run banking organizations.  See Note 19 in the financial statements at Item
8 of this report for a discussion about the Company's risk-based capital ratios.

Prompt Corrective Action

Prompt  Corrective  Action  Regulations of the federal bank regulatory  agencies
establish  five  capital  categories  in  descending  order  (well  capitalized,
adequately  capitalized,  undercapitalized,  significantly  undercapitalized and
critically undercapitalized), assignment to which depends upon the institution's
total risk-based  capital ratio,  Tier 1 risk-based  capital ratio, and leverage
ratio.  Institutions classified in one of the three undercapitalized  categories
are subject to certain mandatory and discretionary  supervisory  actions,  which
include increased  monitoring and review,  implementation of capital restoration
plans,  asset growth  restrictions,  limitations upon expansion and new business
activities, requirements to augment capital, restrictions upon deposit gathering
and interest rates,  replacement of senior executive officers and directors, and
requiring  divestiture or sale of the institution.  The Bank has been classified
as well-capitalized since adoption of these regulations.

                                      -8-



Impact of Monetary Policies

Banking is a business that depends on interest rate  differentials.  In general,
the  difference  between the  interest  paid by a bank on its deposits and other
borrowings, and the interest rate earned by banks on loans, securities and other
interest-earning assets comprises the major source of banks' earnings. Thus, the
earnings and growth of banks are subject to the influence of economic conditions
generally,  both  domestic  and  foreign,  and also to the  monetary  and fiscal
policies of the United  States and its agencies,  particularly  the FRB. The FRB
implements  national  monetary  policy,  such as seeking to curb  inflation  and
combat  recession,  by its  open-market  dealings  in United  States  government
securities,   by  adjusting  the  required   level  of  reserves  for  financial
institutions  subject to reserve  requirements  and through  adjustments  to the
discount  rate  applicable  to borrowings by banks which are members of the FRB.
The  actions  of the FRB in these  areas  influence  the  growth of bank  loans,
investments and deposits and also affect  interest rates.  The nature and timing
of any future changes in such policies and their impact on the Company cannot be
predicted.  In  addition,  adverse  economic  conditions  could  make  a  higher
provision  for loan  losses a prudent  course and could  cause  higher loan loss
charge-offs, thus adversely affecting the Company's net earnings.

Insurance of Deposits

The  Bank's  deposit  accounts  are  insured  up to a maximum  of  $100,000  per
depositor by the FDIC. The FDIC issues regulations and generally  supervises the
operations of its insured  banks.  This  supervision  and regulation is intended
primarily for the protection of depositors, not shareholders.

As of December  31,  2005,  the deposit  insurance  premium rate was $0.0134 per
$100.00 in deposits.  The FDIC is able to increase deposit insurance premiums as
it sees fit every six months. This could result in a significant increase in the
cost of doing business for the Bank in the future.

Securities Laws

The Company is subject to the periodic reporting  requirements of the Securities
and Exchange Act of 1934, as amended, which include filing annual, quarterly and
other  current  reports  with  the  Securities  and  Exchange  Commission.   The
Sarbanes-Oxley  Act was enacted in 2002 to protect  investors by  improving  the
accuracy and  reliability of corporate  disclosures  made pursuant to securities
laws. Among other things, this act:

      -   prohibits  a  registered   public   accounting  firm  from  performing
          specified nonaudit services contemporaneously with a mandatory audit,
      -   requires the chief executive officer and chief financial officer of an
          issuer to  certify  each  annual or  quarterly  report  filed with the
          Securities and Exchange Commission,
      -   requires  an  issuer  to  disclose  all  material   off-balance  sheet
          transactions that may have a material effect on an issuer's  financial
          status, and
      -   prohibits  insider  transactions  in an issuer's stock during lock-out
          periods of an issuer's pension plans.

The Company is also  required to comply  with the rules and  regulations  of the
Nasdaq Stock Market, Inc., on which its common stock is listed.

ITEM 1A. RISK FACTORS

In analyzing whether to make or continue an investment in the Company, investors
should consider, among other factors, the following:

The types of loans in our  portfolio  have a higher  degree of credit risk and a
downturn in our real estate markets could hurt our business.

We  generally  invest a greater  proportion  of our  assets in loans  secured by
commercial  real  estate,  commercial  loans and  consumer  loans  than  savings
institutions  that invest a greater  proportion of their assets in loans secured
by single-family  residences.  Commercial real estate loans and commercial loans
generally  involve  a higher  degree of credit  risk than  residential  mortgage
lending due  primarily  to the large  amounts  loaned to  individual  borrowers.
Losses  incurred on loans to a small number of  borrowers  could have a material
adverse  impact on our income  and  financial  condition.  In  addition,  unlike
residential  mortgage loans,  commercial and commercial real estate loans depend
on the cash flow from the  property or the  business  to service the debt.  Cash
flow may be  significantly  affected by general  economic  conditions.  Consumer
lending is riskier than residential  mortgage lending because consumer loans are
either  unsecured or secured by assets that  depreciate  in value.  See Item 7 -
Loans of this report for  information  as to the percentage of loans invested in
commercial real estate, commercial and consumer loans.

In  addition,  a downturn in our real  estate  markets  could hurt our  business
because  many of our loans are secured by real  estate.  Real estate  values and
real estate markets are generally  affected by changes in national,  regional or
local economic  conditions,  fluctuations in interest rates and the availability
of loans to  potential  purchasers,  changes in tax laws and other  governmental
statutes,  regulations  and policies and acts of nature.  If real estate  prices
decline,  the  value of real  estate  collateral  securing  our  loans  could be
reduced.  Our ability to recover on defaulted  loans by foreclosing  and selling
the real estate  collateral would then be diminished and we would be more likely
to suffer  losses on defaulted  loans.  As of December  31, 2005,  approximately
79.7% of the book value of our loan portfolio consisted of loans  collateralized
by various types of real estate. Substantially all of our real estate collateral
is located  in  California.  If there is a  significant  decline in real  estate
values,  the collateral  for our loans will provide less  security.  Real estate
values could also be affected by, among other things,  earthquakes  and national
disasters  particular to  California.  Any such  downturn  could have a material
adverse effect on our business,  financial condition,  results of operations and
cash flows.

Decreasing interest rates could hurt our profits.

Our ability to earn a profit, like that of most financial institutions,  depends
on our net interest income,  which is the difference between the interest income
we earn on our interest-earning  assets, such as mortgage loans and investments,
and the interest  expense we pay on our  interest-bearing  liabilities,  such as
deposits.  Our  profitability  depends  on our  ability to manage our assets and
liabilities  during  periods of  changing  market  interest  rates.  A sustained
decrease in market  interest  rates could  adversely  affect our earnings.  When
interest rates  decline,  borrowers  tend to refinance  higher-rate,  fixed-rate
loans  at lower  rates.  Under  those  circumstances,  we  would  not be able to
reinvest those prepayments in assets earning interest rates as high as the rates
on the prepaid loans on investment securities.  In addition, our commercial real
estate  and  commercial  loans,  which  carry  interest  rates  that  adjust  in
accordance with changes in the prime rate, will adjust to lower rates.

An economic downturn in California could hurt our profits.

We conduct most of our business in northern and central California.  As a result
of this  geographic  concentration,  our  results are  effected by the  economic
conditions in California.  Deterioration in economic  conditions could result in
the following consequences, any of which could have a material adverse effect on
our business, financial condition, results of operations and cash flows:

      -   problem assets and foreclosures may increase,
      -   demand for our products and services may decline,
      -   low cost or non-interest bearing deposits may decrease, and
      -   collateral for loans made by us,  especially real estate,  may decline
          in value, in turn reducing  customers'  borrowing  power, and reducing
          the value of assets and collateral associated with our existing loans.

                                      -10-



In view of the  concentration of our operations and the collateral  securing our
loan portfolio in both northern and central  California,  we may be particularly
susceptible to the adverse  effects of any of these  consequences,  any of which
could have a  material  adverse  effect on our  business,  financial  condition,
results of operations and cash flows.

Strong competition in California could hurt our profits.

Competition  in the  banking and  financial  services  industry is intense.  Our
profitability  depends upon our continued  ability to successfully  compete.  We
compete  exclusively in northern and central California for loans,  deposits and
customers with commercial banks,  savings and loan associations,  credit unions,
finance  companies,   mutual  funds,  insurance  companies,  and  brokerage  and
investment banking firms. In particular,  our competitors  include several major
financial  companies  whose  greater  resources  may afford  them a  marketplace
advantage by enabling them to maintain  numerous  locations and mount  extensive
promotional and advertising campaigns.  Additionally,  banks and other financial
institutions with larger capitalization and financial intermediaries not subject
to bank regulatory restrictions may have larger lending limits which would allow
them to serve the credit needs of larger customers. Areas of competition include
interest  rates for loans  and  deposits,  efforts  to obtain  loan and  deposit
customers  and a range in quality of products and services  provided,  including
new technology-driven products and services.  Technological innovation continues
to contribute to greater  competition  in domestic and  international  financial
services  markets as  technological  advances  enable more  companies to provide
financial  services.  We  also  face  competition  from  out-of-state  financial
intermediaries that have opened loan production offices or that solicit deposits
in our market areas.  If we are unable to attract and retain banking  customers,
we may be unable to  continue  our loan  growth  and level of  deposits  and our
business,  financial  condition,  results  of  operations  and cash flows may be
adversely affected.

We operate in a highly regulated environment and we may be adversely affected by
changes in laws and  regulations.  Regulations may prevent or impair our ability
to pay dividends, engage in acquisitions or operate in other ways.

We are subject to  extensive  regulation,  supervision  and  examination  by the
California Department of Financial Institutions, or the DFI, the Federal Deposit
Insurance Corporation, and the Board of Governors of the Federal Reserve System.
See Item 1 - Regulation and  Supervision  of this report for  information on the
regulation and supervision which governs our activities.  Regulatory authorities
have  extensive  discretion in their  supervisory  and  enforcement  activities,
including the imposition of restrictions on our operations,  the  classification
of our assets and  determination  of the level of our allowance for loan losses.
Banking  regulations,  designed primarily for the protection of depositors,  may
limit our growth and the return to you, our investors, by restricting certain of
our activities, such as:

      -   the payment of dividends to its shareholders,
      -   possible mergers with or acquisitions of or by other institutions,
      -   desired investments,
      -   loans and interest rates on loans,
      -   interest rates paid on deposits,
      -   the possible expansion of branch offices, and
      -   the ability to provide securities or trust services.

We  also  are  subject  to  capitalization   guidelines  set  forth  in  federal
legislation  and could be subject to  enforcement  actions to the extent that we
are found by regulatory examiners to be undercapitalized. We cannot predict what
changes,  if any,  will be made to existing  federal and state  legislation  and
regulations or the effect that such changes may have on our future  business and
earnings prospects. Any change in such regulation and oversight,  whether in the
form of regulatory policy,  regulations,  legislation or supervisory action, may
have a material impact on our operations.

We are exposed to risks in connection with the loans we make.

A significant source of risk for us arises from the possibility that losses will
be  sustained  because  borrowers,  guarantors  and related  parties may fail to
perform in accordance  with the terms of their loans. We have  underwriting  and
credit  monitoring  procedures and credit policies,  including the establishment
and review of the allowance for loan losses,  that we believe to be  appropriate
to minimize this risk by assessing the  likelihood of  nonperformance,  tracking
loan performance and diversifying our respective loan portfolios.  Such policies
and procedures,  however, may not prevent unexpected losses that could adversely
affect our results of operations.

                                      -11-



Technological advances impact our business.

The  banking  industry  is  undergoing   technological   changes  with  frequent
introductions  of new  technology-driven  products and services.  In addition to
improving  customer  services,   the  effective  use  of  technology   increases
efficiency  and  enables  financial  institutions  to reduce  costs.  Our future
success  will  depend,  in part,  on our  ability  to  address  the needs of our
customers by using technology to provide products and services that will satisfy
customer demands for convenience as well as to create additional efficiencies in
our operations.  Many of our competitors have  substantially  greater  resources
than  we do to  invest  in  technological  improvements.  We may  not be able to
effectively   implement   new   technology-driven   products   and  services  or
successfully market such products and services to our customers.

There are potential risks associated with future acquisitions and expansions.

We intend to continue to explore expanding our branch system through opening new
bank  branches and in-store  branches in existing or new markets in northern and
central  California.  In the ordinary course of business,  we evaluate potential
branch  locations that would bolster our ability to cater to the small business,
individual and residential lending markets in California.  Any given new branch,
if and when opened, will have expenses in excess of revenues for varying periods
after  opening that may  adversely  affect our results of  operations or overall
financial condition.

In  addition,  to the extent  that we acquire  other  banks in the  future,  our
business  may be  negatively  impacted  by  certain  risks  inherent  with  such
acquisitions. These risks include:

      -   incurring  substantial  expenses  in pursuing  potential  acquisitions
          without completing such acquisitions,
      -   losing key clients as a result of the change of ownership to us,
      -   the  acquired   business  not   performing  in  accordance   with  our
          expectations,
      -   difficulties  arising  in  connection  with  the  integration  of  the
          operations of the acquired business with our operations,
      -   needing to make significant investments and infrastructure,  controls,
          staff,   emergency  backup   facilities  or  other  critical  business
          functions that become strained by our growth,
      -   management  needing  to divert  attention  from  other  aspects of our
          business,
      -   potentially losing key employees of the acquired business,
      -   incurring  unanticipated  costs which could  reduce our  earnings  per
          share,
      -   assuming potential  liabilities of the acquired company as a result of
          the acquisition, and
      -   an  acquisition  may dilute our earnings per share,  in both the short
          and long term, or it may reduce our tangible capital ratios.

As result of these risks, any given  acquisition,  if and when consummated,  may
adversely affect our results of operations or financial condition.  In addition,
because the  consideration  for an  acquisition  may involve  cash,  debt or the
issuance of shares of our stock and may  involve  the payment of a premium  over
book and  market  values,  existing  shareholders  may  experience  dilution  in
connection with any acquisition.

Compliance  with  changing   regulation  of  corporate   governance  and  public
disclosure may result in additional risks and expenses.

Changing laws,  regulations and standards  relating to corporate  governance and
public  disclosure,  including the Sarbanes-Oxley Act of 2002 and new Securities
and   Exchange   Commission   regulations,    are   creating   uncertainty   for
publicly-traded  companies such as TriCo. These laws,  regulations and standards
are subject to varying  interpretations  in many cases and,  as a result,  their
application  in  practice  may evolve  over time as new  guidance is provided by
regulatory and governing  bodies,  which could result in continuing  uncertainty
regarding  compliance matters and higher costs necessitated by ongoing revisions
to disclosure and  governance  practices.  We are committed to maintaining  high
standards  of  corporate  governance  and public  disclosure.  As a result,  our
efforts to comply with evolving  laws,  regulations  and standards have resulted
in, and are likely to continue to result in, increased  expenses and a diversion
of management  time and  attention.  In  particular,  our efforts to comply with
Section  404 of the  Sarbanes-Oxley  Act of  2002  and the  related  regulations
regarding   management's  required  assessment  of  its  internal  control  over
financial  reporting and its external  auditors'  audit of that  assessment  has
required the commitment of significant  financial and managerial  resources.  We
expect  these  efforts  to  require  the  continued  commitment  of  significant
resources.  Further, the members of our board of directors, members of our audit
or compensation  committees,  our chief executive  officer,  our chief financial
officer and certain other  executive  officers  could face an increased  risk of
personal  liability in connection with the  performance of their duties.  It may
also become more  difficult  and more  expensive to obtain  director and officer
liability  insurance.  As a result,  our ability to attract and retain executive
officers and qualified board and committee members could be more difficult.

                                      -12-



Our growth and expansion may strain our ability to manage our operations and our
financial resources.

Our financial performance and profitability depend on our ability to execute our
corporate  growth  strategy.  In addition to seeking  deposit and loan and lease
growth in our existing  markets,  we may pursue  expansion  opportunities in new
markets.  Continued  growth,  however,  may present operating and other problems
that  could  adversely  affect our  business,  financial  condition,  results of
operations and cash flows.  Accordingly,  there can be no assurance that we will
be able to execute our growth  strategy or maintain  the level of  profitability
that we have recently experienced.

Our growth may place a strain on our  administrative,  operational and financial
resources and increase demands on our systems and controls. This business growth
may  require  continued  enhancements  to and  expansion  of our  operating  and
financial  systems and controls and may strain or significantly  challenge them.
In  addition,   our  existing   operating  and  financial  control  systems  and
infrastructure  may not be adequate to maintain and  effectively  monitor future
growth. Our continued growth may also increase our need for qualified personnel.
We cannot assure you that we will be successful in attracting,  integrating  and
retaining such personnel.

We depend on key  personnel  and the loss of one or more of those key  personnel
may materially and adversely affect our prospects.

Competition  for qualified  employees  and personnel in the banking  industry is
intense and there are a limited  number of qualified  persons with knowledge of,
and experience in, the California  community  banking  industry.  The process of
recruiting  personnel with the combination of skills and attributes  required to
carry out our strategies is often lengthy.  Our success depends to a significant
degree  upon our  ability  to  attract  and retain  qualified  management,  loan
origination, finance, administrative, marketing and technical personnel and upon
the continued contributions of our management and personnel. In particular,  our
success has been and continues to be highly  dependent upon the abilities of our
senior  executive  management  team of Messrs.  Smith,  O'Sullivan,  Mastorakis,
Hagstrom,  Reddish,  Carney,  Miller and Rios, who have expertise in banking and
experience  in the  California  markets  we serve and have  targeted  for future
expansion.  We also  depend  upon a  number  of  other  key  executives  who are
California  natives  or  are  long-time   residents  and  who  are  integral  to
implementing  our  business  plan.  The loss of the  services  of any one of our
senior  executive  management team or other key executives could have a material
adverse effect on our business,  financial condition,  results of operations and
cash flows.

Our business is subject to interest rate risk and  variations in interest  rates
may negatively affect our financial performance.

A substantial portion of our income is derived from the differential or "spread"
between the  interest  earned on loans,  securities  and other  interest-earning
assets,  and interest paid on deposits,  borrowings  and other  interest-bearing
liabilities.  Because  of  the  differences  in  the  maturities  and  repricing
characteristics of our interest-earning assets and interest-bearing liabilities,
changes in interest rates do not produce  equivalent  changes in interest income
earned  on  interest-earning   assets  and  interest  paid  on  interest-bearing
liabilities.  Accordingly, fluctuations in interest rates could adversely affect
our interest  rate spread and, in turn,  our  profitability.  In addition,  loan
origination  volumes are  affected by market  interest  rates.  Rising  interest
rates, generally,  are associated with a lower volume of loan originations while
lower  interest  rates are usually  associated  with  higher loan  originations.
Conversely,  in rising  interest rate  environments,  loan  repayment  rates may
decline and in falling  interest rate  environments,  loan  repayment  rates may
increase.  Although we have been  successful in generating  new loans and leases
during 2005, the continuation of historically low long-term interest rate levels
may cause  additional  refinancing  of  commercial  real  estate  and 1-4 family
residence  loans,  which may depress our loan volumes or cause rates on loans to
decline.  In addition,  an increase in the general level of short-term  interest
rates on  variable  rate  loans may  adversely  affect  the  ability  of certain
borrowers to pay the interest on and  principal of their  obligations  or reduce
the amount they wish to borrow.  Additionally,  as short-term  market rates have
risen over the past  eighteen  months,  although we have  increased the rates we
paid  on  borrowings  and  other  interest-bearing   liabilities,  we  have  not
proportionally increased interest rates we paid on deposits. If short-term rates
continue to rise, in order to retain existing deposit  customers and attract new
deposit  customers  we may need to  increase  rates we pay on deposit  accounts.
Because we have deferred  increasing  rates we paid on deposit accounts during a
period of rising  short-term market rates, we may need to accelerate the pace of
rate  increases  on our  deposit  accounts  as  compared  to the pace of  future
increases in short-term market rates.  Accordingly,  changes in levels of market
interest rates could  materially and adversely  affect our net interest  spread,
asset quality, loan origination volume, business,  financial condition,  results
of operations and cash flows.

                                      -13-



If we cannot attract deposits, our growth may be inhibited.

We plan to increase the level of our assets,  including our loan portfolio.  Our
ability to increase  our assets  depends in large part on our ability to attract
additional deposits at favorable rates. We intend to seek additional deposits by
offering  deposit  products  that are  competitive  with those  offered by other
financial institutions in our markets and by establishing personal relationships
with our customers.  We cannot assure you that these efforts will be successful.
Our inability to attract  additional  deposits at competitive rates could have a
material  adverse  effect  on our  business,  financial  condition,  results  of
operations and cash flows.

Our allowance for loan losses may not be adequate to cover actual losses.

A significant  source of risk arises from the  possibility  that losses could be
sustained because borrowers, guarantors, and related parties may fail to perform
in  accordance  with the  terms of their  loans.  The  underwriting  and  credit
monitoring policies and procedures that we have adopted to address this risk may
not prevent  unexpected  losses that could have a material adverse effect on our
business,  financial condition, results of operations and cash flows. Unexpected
losses may arise from a wide  variety of specific or systemic  factors,  many of
which are beyond  our  ability  to  predict,  influence,  or  control.  Like all
financial institutions,  we maintain an allowance for loan losses to provide for
loan  defaults and  non-performance.  Our  allowance  for loan losses may not be
adequate to cover  actual loan  losses,  and future  provisions  for loan losses
could materially and adversely affect our business, financial condition, results
of  operations  and cash  flows.  The  allowance  for loan losses  reflects  our
estimate of the probable  losses in our loan  portfolio at the relevant  balance
sheet date. Our allowance for loan losses is based on prior experience,  as well
as an evaluation of the known risks in the current  portfolio,  composition  and
growth of the loan  portfolio  and economic  factors.  The  determination  of an
appropriate level of loan loss allowance is an inherently  difficult process and
is based on numerous assumptions.  The amount of future losses is susceptible to
changes  in  economic,  operating  and other  conditions,  including  changes in
interest  rates,  that may be beyond  our  control  and these  losses may exceed
current estimates. Federal and state regulatory agencies, as an integral part of
their examination process, review our loans and allowance for loan losses. While
we believe  that our  allowance  for loan losses is  adequate  to cover  current
losses,  we cannot  assure you that we will not increase the  allowance for loan
losses  further  or  that  regulators  will  not  require  us to  increase  this
allowance.  Either of these  occurrences could have a material adverse affect on
our business, financial condition and results of operations.

We rely on communications,  information, operating and financial control systems
technology from third-party service providers, and we may suffer an interruption
in those systems that may result in lost business.  We may not be able to obtain
substitute  providers on terms that are as favorable if our  relationships  with
our existing service providers are interrupted.

We rely heavily on third-party service providers for much of our communications,
information,  operating and financial control systems technology. Any failure or
interruption  or breach in security of these systems could result in failures or
interruptions in our customer relationship management,  general ledger, deposit,
servicing and loan origination  systems. We cannot assure you that such failures
or  interruptions  will not  occur  or,  if they do  occur,  that  they  will be
adequately addressed by us or the third parties on which we rely. The occurrence
of any failures or  interruptions  could have a material  adverse  effect on our
business,  financial condition,  results of operations and cash flows. If any of
our  third-party  service  providers   experience   financial,   operational  or
technological  difficulties,  or  if  there  is  any  other  disruption  in  our
relationships  with them,  we may be required to locate  alternative  sources of
such services,  and we cannot assure you that we could  negotiate terms that are
as favorable to us, or could obtain services with similar functionality as found
in our existing systems without the need to expend substantial resources,  if at
all.  Any of these  circumstances  could have a material  adverse  effect on our
business, financial condition, results of operations and cash flows.

                                      -14-



Our future  ability to pay  dividends is subject to  restrictions.  As a result,
capital  appreciation,  if any,  of our common  stock may be your sole source of
gains in the future.

Since  we are a  holding  company  with no  significant  assets  other  than Tri
Counties  Bank,  we  currently  depend  upon  dividends  from  the  bank  for  a
substantial portion of our revenues. Our ability to continue to pay dividends in
the future will  continue to depend in large part upon our receipt of  dividends
or other  capital  distributions  from Tri  Counties  Bank.  The  ability of Tri
Counties  Bank to pay  dividends or make other  capital  distributions  to us is
subject to the  regulatory  authority of the DFI. As of December  31, 2005,  the
Bank could have paid  approximately  $47 million in dividends  without the prior
approval of the Federal  Reserve or the DFI. The amount that Tri  Counties  Bank
may pay in  dividends is further  restricted  due to the fact that the bank must
maintain  a  certain  minimum  amount  of  capital  to  be  considered  a  "well
capitalized"   institution  as  further   described   under  Item  1  -  Capital
Requirements in this report.

From  time to  time,  we may  become a party to  financing  agreements  or other
contractual  arrangements  that have the effect of limiting or prohibiting us or
Tri  Counties  Bank from  declaring  or paying  dividends.  Our holding  company
expenses and  obligations  with respect to our trust  preferred  securities  and
corresponding  junior  subordinated  deferrable interest debentures issued by us
may limit or impair  our  ability  to declare  or pay  dividends.  Finally,  our
ability to pay dividends is also subject to the  restrictions  of the California
Corporations Code.

Only a limited  trading  market  exists for our common stock which could lead to
price volatility.

Our common  stock is quoted on the Nasdaq  National  Market and trading  volumes
have been  modest.  The limited  trading  market for our common  stock may cause
fluctuations in the market value of our common stock to be exaggerated,  leading
to price volatility in excess of that which would occur in a more active trading
market of our common  stock.  In addition,  even if a more active  market in our
common stock develops,  we cannot assure you that such a market will continue or
that shareholders will be able to sell their shares.

If we fail to maintain an effective system of internal and disclosure control,
we may not be able to accurately report our financial results or prevent fraud.
As a result, current and potential shareholders could lose confidence in our
financial reporting, which would harm our business and the trading price of our
securities.

Effective  internal  and  disclosure  controls are  necessary  for us to provide
reliable  financial  reports  and  effectively  prevent  fraud  and  to  operate
successfully  as a public  company.  If we  cannot  provide  reliable  financial
reports or prevent fraud, our reputation and operating  results would be harmed.
We review  and  analyze  our  internal  control  over  financial  reporting  for
Sarbanes-Oxley  Section 404 compliance.  As part of that process we may discover
material  weaknesses  or  significant  deficiencies  in our internal  control as
defined  under  standards  adopted by the Public  Company  Accounting  Oversight
Board,  or  PCAOB,  that  require  remediation.  Under the  PCAOB  standards,  a
"material  weakness" is a significant  deficiency or  combination of significant
deficiencies,  that  results  in more than a remote  likelihood  that a material
misstatement of the annual or interim financial statements will not be prevented
or detected.  A "significant  deficiency" is a control deficiency or combination
of control deficiencies,  that adversely affect a company's ability to initiate,
authorize,  record,  process,  or report  external  financial  data  reliably in
accordance with generally  accepted  accounting  principles such that there is a
more than remote likelihood that a misstatement of a company's annual or interim
financial  statements that is more than inconsequential will not be prevented or
detected.

                                      -15-



As a result of weaknesses that may be identified in our internal control, we may
also  identify  certain  deficiencies  in some of our  disclosure  controls  and
procedures that we believe require remediation.  If we discover  weaknesses,  we
will make efforts to improve our internal and disclosure control. However, there
is no assurance  that we will be successful.  Any failure to maintain  effective
controls  or  timely  effect  any  necessary  improvement  of our  internal  and
disclosure controls could harm operating results or cause us to fail to meet our
reporting obligations,  which could affect our ability to remain listed with the
Nasdaq National Market.  Ineffective internal and disclosure controls could also
cause investors to lose confidence in our reported financial information,  which
would likely have a negative effect on the trading price of our securities.

Anti-takeover  provisions and federal law may limit the ability of another party
to acquire us, which could cause our stock price to decline.

Various  provisions of our articles of  incorporation  and bylaws could delay or
prevent a third party from acquiring us, even if doing so might be beneficial to
our shareholders. These provisions provide for, among other things:

      -   specified  actions that the Board of Directors  shall or may take when
          an offer to merge, an offer to acquire all assets or a tender offer is
          received,
      -   a  shareholder  rights  plan  which  could  deter a  tender  offer  by
          requiring a potential acquisitor to pay a substantial premium over the
          market price of our common stock,
      -   advance  notice  requirements  for proposals that can be acted upon at
          shareholder meetings, and
      -   the  authorization  to issue preferred stock by action of the board of
          directors acting alone, thus without obtaining shareholder approval.

The Bank Holding Company Act of 1956, as amended, and the Change in Bank Control
Act of 1978,  as amended,  together  with  federal  regulations,  require  that,
depending on the particular circumstances,  either Federal Reserve approval must
be  obtained  or  notice  must  be  furnished  to the  Federal  Reserve  and not
disapproved prior to any person or entity acquiring  "control" of a state member
bank,  such as Tri  Counties  Bank.  These  provisions  may  prevent a merger or
acquisition  that would be attractive to shareholders  and could limit the price
investors would be willing to pay in the future for our common stock.

We are exposed to risk of  environmental  liabilities with respect to properties
to which we take title.

In the course of our  business,  we may  foreclose and take title to real estate
and  could  be  subject  to  environmental  liabilities  with  respect  to these
properties.  We may be held liable to a governmental  entity or to third parties
for property damage, personal injury,  investigation and clean-up costs incurred
by these  parties in  connection  with  environmental  contamination,  or may be
required to investigate or clean-up  hazardous or toxic substances,  or chemical
releases at a property.  The costs associated with  investigation or remediation
activities  could be  substantial.  In  addition,  if we are the owner or former
owner of a  contaminated  site,  we may be subject to common law claims by third
parties based on damages and costs  resulting from  environmental  contamination
emanating from the property.  If we become subject to significant  environmental
liabilities,  our business,  financial condition, results of operations and cash
flows could be materially adversely affected.

We could sustain losses if our asset quality declines.

Our earnings are  significantly  affected by our ability to properly  originate,
underwrite and service loans.  We could sustain losses if we incorrectly  assess
the  creditworthiness  of  our  borrowers  or  fail  to  detect  or  respond  to
deterioration  in asset quality in a timely manner.  Problems with asset quality
could cause our  interest  income and net  interest  margin to decrease  and our
provisions for loan losses to increase, which could adversely affect our results
of operations and financial condition.

Our recent results may not be indicative of our future results.

We may not be able to sustain our  historical  rate of growth or may not even be
able to grow our business at all. Various factors,  such as economic conditions,
regulatory and legislative  considerations  and competition,  may also impede or
prohibit  our  ability  to  expand  our  market  presence.  If we  experience  a
significant decrease in our historical rate of growth, our results of operations
and financial  condition may be adversely  affected due to a high  percentage of
our operating costs being fixed expenses.

                                      -16-



The amount of common stock owned by, and other  compensation  arrangements with,
our  officers and  directors  may make it more  difficult to obtain  shareholder
approval of potential takeovers that they oppose.

As of March  7,  2006,  directors  and  executive  officers  beneficially  owned
approximately  21% of our  common  stock and our ESOP  owned  approximately  8%.
Agreements  with our senior  management  also provide for  significant  payments
under certain  circumstances  following a change in control.  These compensation
arrangements,  together with the common stock and option  ownership of our board
of  directors  and  management,  could make it  difficult or expensive to obtain
majority support for shareholder proposals or potential acquisition proposals of
us that our directors and officers oppose.

We may issue  additional  common stock or other equity  securities in the future
which could dilute the ownership interest of existing shareholders

In order to maintain our capital at desired or regulatorily-required  levels, or
to fund future  growth,  our board of directors  may decide from time to time to
issue  additional  shares of  common  stock,  or  securities  convertible  into,
exchangeable  for or representing  rights to acquire shares of our common stock.
The sale of these shares may significantly  dilute your ownership  interest as a
shareholder.  New investors in the future may also have rights,  preferences and
privileges  senior to our current  shareholders  which may adversely  impact our
current shareholders.

Holders of our junior  subordinated  debentures  have  rights that are senior to
those of our common stockholders.

We have supported our continued  growth through the issuance of trust  preferred
securities  from special  purpose trusts and  accompanying  junior  subordinated
debentures.  At December 31, 2005, we had outstanding trust preferred securities
and accompanying junior subordinated  debentures totaling $41,238,000.  Payments
of  the  principal  and  interest  on  the  trust   preferred   securities   are
conditionally  guaranteed by us. Further,  the accompanying  junior subordinated
debentures we issued to the trusts are senior to our shares of common stock.  As
a result, we must make payments on the junior subordinated debentures before any
dividends  can be paid on our common stock and, in the event of our  bankruptcy,
dissolution or liquidation,  the holders of the junior  subordinated  debentures
must be satisfied before any distributions can be made on our common stock.

ITEM 1B. UNRESOLVED STAFF COMMENTS

1Stock prices adjusted to reflect 2-for-1 stock split effected April 30, 2004.


As of March 7, 2006 there were approximately 1,754 shareholders of record of the
Company's common stock.

The Company has paid cash  dividends on its common stock in every  quarter since
March 1990,  and it is currently  the intention of the Board of Directors of the
Company to continue payment of cash dividends on a quarterly basis.  There is no
assurance,  however,  that any  dividends  will be paid since they are dependent
upon earnings,  financial condition and capital  requirements of the Company and
the Bank.  As of December 31, 2005,  $47,054,000  was  available  for payment of
dividends  by the  Company  to  its  shareholders,  under  applicable  laws  and
regulations.  The Company  paid cash  dividends of $0.12 per common share in the
quarter ended December 31, 2005,  $0.11 per common share in each of the quarters
ended  September  30, 2005,  June 30, 2005,  March 31, 2005,  December 31, 2004,

Stock Repurchase Plan

The Company adopted a stock  repurchase plan on July 31, 2003, which was amended
on March 11, 2004 for the  repurchase  of up to 500,000  shares of the Company's
common stock from time to time as market  conditions  allow.  The 500,000 shares
authorized for repurchase under this plan represented  approximately 3.2% of the
Company's  approximately  15,704,000  common shares  outstanding  as of July 31,
2003.  This  plan  has no  stated  expiration  date for the  repurchases.  As of
December 31, 2005,  the Company had purchased  374,371 shares under this plan as
adjusted  for the  2-for-1  stock split in the form of a common  stock  dividend

ITEM 7. MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

The Company's  discussion and analysis of its financial condition and results of
operations  is intended  to provide a better  understanding  of the  significant
changes and trends  relating to the Company's  financial  condition,  results of
operations, liquidity, interest rate sensitivity, off balance sheet arrangements
and certain contractual  obligations.  The following  discussion is based on the
Company's   consolidated  financial  statements  which  have  been  prepared  in
accordance with accounting principles generally accepted in the United States of
America. Please read the Company's audited consolidated financial statements and
the related notes included as Item 8 of this report.

Critical Accounting Policies and Estimates

The Company's  discussion and analysis of its financial condition and results of
operations are based upon the Company's consolidated financial statements, which
have been prepared in accordance with accounting  principles  generally accepted
in the United States of America.  The preparation of these financial  statements
requires the Company to make  estimates and  judgments  that affect the reported
amounts of assets, liabilities, revenues and expenses, and related disclosure of
contingent  assets and liabilities.  On an on-going basis, the Company evaluates
its estimates,  including those that materially affect the financial  statements
and are related to the adequacy of the allowance  for loan losses,  investments,
mortgage  servicing  rights,  and  intangible  assets.  The  Company  bases  its
estimates on historical  experience  and on various other  assumptions  that are
believed to be reasonable under the circumstances, the results of which form the
basis for making  judgments  about the carrying values of assets and liabilities
that are not readily apparent from other sources. Actual results may differ from
these  estimates  under  different  assumptions  or  conditions.  The  Company's
policies  related to estimates  on the  allowance  for loan  losses,  other than
temporary  impairment of investments and impairment of intangible assets, can be
found in Note 1 to the Company's audited  consolidated  financial statements and
the related notes included as Item 8 of this report.

The Company  uses the  intrinsic  value  method to account for its stock  option
plans (in accordance with the provisions of Accounting  Principles Board Opinion
No. 25).  Under this method,  compensation  expense is recognized  for awards of
options to purchase shares of common stock to employees under compensatory plans
only if the fair  market  value of the stock at the option  grant date (or other
measurement  date, if later) is greater than the amount the employee must pay to
acquire  the  stock.  Statement  of  Financial  Accounting  Standards  No.  123,
Accounting for Stock-Based Compensation (SFAS 123) permits companies to continue
using the  intrinsic  value  method  or to adopt a fair  value  based  method to
account  for  stock  option  plans.  The fair  value  based  method  results  in
recognizing as expense over the vesting period the fair value of all stock-based
awards  on the  date of  grant.  The  Company  elected  to  continue  to use the
intrinsic  value method.  In December 2004, the Financial  Accounting  Standards
Board (FASB)  issued FASB  Statement of Financial  Accounting  Standards No. 123
(revised 2004), Share-Based Payment (SFAS 123R), which replaces SFAS No. 123 and
supersedes  APB Opinion No. 25. SFAS 123R requires all  share-based  payments to
employees,  including grants of employee stock options,  to be recognized in the
financial statements based on their fair values beginning with the first interim
reporting  period of the Company's  fiscal year  beginning  after June 15, 2005,
with early adoption encouraged.  The pro forma disclosures  previously permitted
under  SFAS  123  no  longer  will  be an  alternative  to  financial  statement
recognition. The Company adopted SFAS 123R on January 1, 2006 using the modified
prospective  method  that  requires  compensation  expense be  recorded  for all
unvested stock options at January 1, 2006. The Company expects that the adoption
of SFAS 123R will impact the Company's  consolidated  results of operations  and
earnings  per share  similarly to the current pro forma  disclosures  under SFAS
123.

As the Company has not  commenced  any business  operations  independent  of the
Bank, the following discussion pertains primarily to the Bank. Average balances,
including  balances used in calculating  certain financial ratios, are generally
comprised  of  average  daily  balances  for the  Company.  Within  Management's
Discussion  and  Analysis of  Financial  Condition  and  Results of  Operations,
interest  income and net  interest  income are  generally  presented  on a fully
tax-equivalent (FTE) basis.

                                      -21-



The  following   discussion  and  analysis  is  designed  to  provide  a  better
understanding  of the significant  changes and trends related to the Company and
the  Bank's  financial  condition,   operating  results,   asset  and  liability
management,  liquidity and capital  resources and should be read in  conjunction
with the consolidated  financial statements of the Company and the related notes
at Item 8 of this report.

Interest  income (FTE) increased  $13,835,000  (16.1%) from 2004 to 2005, due to
increased  volume of earning assets and higher yields on earning assets.  During
2005, the average  balance of  interest-earning  assets  increased  $178,629,000
(13.1%).  The average yield on the Company's earning assets increased from 6.30%
in 2004 to 6.47% in 2005.  The  increase  in average  yield on  interest-earning
assets  increased  interest  income (FTE) by  $1,268,000,  while the increase in
average balances of interest-earning assets added $12,567,000 to interest income
(FTE) during 2005.

Interest  expense  increased  $7,166,000  (53.6%)  in 2005  from  2004  due to a
$122,117,000 (11.3%) increase in average balance of interest-bearing liabilities
and a 47 basis  point  increase  in the  average  rate paid on  interest-bearing
liabilities   from  1.23%  to  1.70%.   The   increase   in  average   yield  on

increase in average balances of interest-bearing liabilities added $2,857,000 to
interest expense during 2005.

Interest income (FTE) increased  $10,858,000  (14.5%) from 2003 to 2004, the net
effect of higher  average  balances of those  assets  partially  offset by lower
earning-asset  yields.  The total yield on earning  assets dropped from 6.34% in
2003 to 6.30% in 2004,  following the trend in overall interest markets in which
federal funds rates were reduced in mid-2003 from 1.25% to 1.00%, rose beginning
in mid-2004,  and ended 2004 at 2.25%.  The average yield on loans  decreased 52
basis  points  to  6.85%  during  2004.   The  decrease  in  average   yield  on
interest-earning  assets reduced  interest  income (FTE) by $4,466,000,  while a
$180,193,000  (15.2%)  increase in average balances of  interest-earning  assets
added $15,324,000 to interest income (FTE) during 2004.

Interest  expense  increased  $274,000 (2.1%) in 2004 from 2003, due to a higher
average balance of  interest-bearing  liabilities  that was partially  offset by
lower rates paid.  The average  rate paid on  interest-bearing  liabilities  was
1.23% in 2004,  16 basis points lower than in 2003.  The decrease in the average
rate  paid  on  interest-bearing   liabilities  decreased  interest  expense  by
$1,510,000 from 2003 to 2004,  while a $142,598,000  (15.2%) increase in average
balances  of   interest-bearing   liabilities   increased  interest  expense  by
$1,784,000 in 2004.

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

During  2003,   it  became   increasingly   difficult   to  decrease   rates  on
interest-bearing  liabilities as market interest rates continued to decrease and
hit a low in  mid-2003.  In  addition,  the  positive  impact  of all  other net
noninterest  bearing  funds on net interest  margin was reduced due to the lower
market  rates of  interest at which they could be  invested.  During  2004,  the
Company  was  able to  slightly  improve  its net  interest  margin  by  further
decreasing  rates  paid on  interest-bearing  deposits  even  though  short-term
interest  rates  began  to rise  from  their  lows  in  mid-2004.  During  2005,
short-term  interest  rates  continued to rise while  long-term  interest  rates
remained steady or decreased slightly. As a result the average yield the Company
was able to earn on interest-earning assets did not increase as fast as the rate
it paid on interest-bearing liabilities, thus decreasing net interest margin.

Summary of Average Balances, Yields/Rates and Interest Differential

The following tables present,  for the past three years,  information  regarding
the Company's consolidated average assets, liabilities and shareholders' equity,
the amounts of interest income from average earning assets and resulting yields,
and the amount of interest expense paid on interest-bearing liabilities. Average
loan balances include  nonperforming  loans.  Interest income includes  proceeds
from  loans on  nonaccrual  loans  only to the extent  cash  payments  have been
received and applied to interest income.  Yields on securities and certain loans
have been adjusted  upward to reflect the effect of income  thereon  exempt from
federal  income  taxation  at  the  current   statutory  tax  rate  (dollars  in
thousands):

     assets less the average rate paid on interest-bearing liabilities.
(2)  Net interest  margin is computed by dividing  net interest  income by total
     average earning assets.

of total loans were 0.21% and 0.42% at December 31, 2005 and 2004, respectively.
The ratio of allowance  for loan losses to  nonperforming  loans was 548% at the

In 2004, the Company provided  $2,901,000 for loan losses compared to $1,058,000
in 2003.  The increase in the loan loss  provision in 2004 was mainly due to the

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

Noninterest  income  increased  $96,000 (0.4%) to  $24,890,000 in 2005.  Service
charges on deposit  accounts was up $380,000 (2.9%) due to the introduction of a
business overdraft privilege product and an increase in overdraft fees. ATM fees
and  interchange,  and other service fees were up $487,000  (18.4%) and $116,000
(6.0%) due to expansion of the  Company's  ATM network and customer base through
de-novo branch expansion and existing branch growth.  Overall,  mortgage banking
activities,  which includes amortization of mortgage servicing rights,  mortgage
servicing fees, provision for mortgage servicing valuation  allowance,  and gain
on sale of  loans,  accounted  for  $1,946,000  of  noninterest  income  in 2005
compared to $2,448,000  in 2004.  Included in the mortgage  banking  results for
2004 was a $600,000 recovery of mortgage  servicing rights valuation  allowance.
Commissions on sale of nondeposit  investment  products decreased $85,000 (3.7%)
in 2005 due to slightly  lower demand for annuity  products.  Other  noninterest
income  decreased  $308,000  (19.0%) in 2005 primarily due to a $566,000 gain on
sale of foreclosed assets recorded in 2004.

Noninterest  income increased  $1,885,000 (8.2%) to $24,794,000 in 2004. Service
charges on deposit  accounts were up $744,000  (6.0%) due to growth in number of
customers.  ATM fees and  interchange,  and other  service fees were up $432,000
(19.5%) and $157,000  (8.8%) due to expansion of the  Company's  ATM network and
customer  base through  de-novo  branch  expansion.  Overall,  mortgage  banking
activities,  which includes amortization of mortgage servicing rights,  mortgage
servicing fees, provision for mortgage servicing valuation  allowance,  and gain
on sale of loans,  accounted for  $2,448,000 of  noninterest  income in the 2004
compared to $3,061,000  in 2003.  The decrease in the  amortization  of mortgage
servicing  rights and the  recovery of mortgage  servicing  valuation  allowance
taken in 2004 are the  result  of the  recent  slowdown  in  mortgage  refinance
activity. While the Company benefits from decreased amortization and recovery of
mortgage servicing valuations of mortgage servicing rights during periods of low
levels of mortgage refinance activity,  it may also experience decreased gain on
sale of loans.  Commissions on sale of nondeposit  investment products increased
$561,000  (31.8%)  in 2004 due to higher  demand  for  annuity  products.  Other
noninterest  income increased $677,000 (71.9%) to $1,618,000 due to increases in
gain on sale of foreclosed  assets and lease brokerage  income from $113,000 and
$0, respectively, in 2003 to $566,000 and $227,000, respectively, in 2004.

December 31, 2005, and annual salary increases. Incentive and commission related
salary expenses  increased  $534,000 (11.8%) to $5,053,000 in 2005. The increase
in incentive  and  commission  expenses was directly tied to  significant  loan,
deposit, and revenue growth during 2005. Benefits expense, including retirement,
medical and  workers'  compensation  insurance,  and taxes,  increased  $230,000
(3.0%) to $7,963,000 during 2005.

Salary and benefit expenses increased  $3,477,000 (11.7%) to $33,191,000 in 2004
compared to 2003. Base salaries  increased  $1,867,000  (9.8%) to $20,939,000 in
2004. The increase in base salaries was mainly due to a 6.3% increase in average
full time equivalent  employees from 505 at December 31, 2003 to 537 at December
31,  2004,  primarily  due to the  opening of  branches  in Folsom,  Turlock and
Woodland  in  December  2003,  April  2004,  and  November  2004,  respectively.
Incentive and commission  related salary  expenses  increased  $65,000 (1.5%) to
$4,519,000  in 2004.  The small  increase in incentive  and  commission  related
salary expense is consistent with  performance  targets being reached to similar
extents in 2004 and 2003.  These results are consistent with the Bank's strategy
of working more  efficiently  with fewer  employees who are  compensated in part
based on their  business  unit's  performance  or on their  ability to  generate
revenue.   Benefits  expense,   including   retirement,   medical  and  workers'
compensation  insurance,  and taxes,  increased $1,545,000 (25.0%) to $7,733,000
during 2004.

Other  noninterest  expense  increased  $547,000  (2.0%) to $28,184,000 in 2005.
Increases in the areas of equipment and data processing, occupancy, advertising,
ATM network  charges and courier  service were mainly due to the first full year
of  operation  of the  Turlock  and  Woodland  branches,  the opening in 2005 of
branches in Lincoln, Folsom, Sacramento, and Roseville, and enhancements to data
processing  and ATM network  equipment.  The decrease in  professional  fees was
mainly due to reduced  legal  expenses  and  consulting  fees.  The  decrease in
consulting fees was mainly due to the expiration of consulting  services related
to the Company's  overdraft  privilege  product,  the expiration of which is not
expected to have an impact on revenue from the overdraft privilege product.

Other noninterest  expenses increased  $1,632,000 (6.3%) to $27,637,000 in 2004.
Increases  in  the  areas  of   equipment   and  data   processing,   occupancy,
telecommunications, and courier service from 2003 to 2004 were mainly due to the
opening of branches  in Folsom,  Turlock and  Woodland in December  2003,  April
2004, and November 2004, respectively.

Provision for Taxes

The effective tax rate on income was 39.1%,  38.2%, and 37.5% in 2005, 2004, and
2003,  respectively.  The  effective  tax rate  was  greater  than  the  federal
statutory  tax rate due to state tax  expense  of  $3,993,000,  $3,008,000,  and
$2,636,000,  respectively,  in these  years.  Tax-exempt  income of  $1,778,000,
$1,728,000,  and  $1,940,000,  respectively,  from  investment  securities,  and
$1,507,000,  $1,499,000,  and  $1,296,000,  respectively,  from increase in cash
value of life insurance in these years helped to reduce the effective tax rate.

Loans

The Bank concentrates its lending activities in four principal areas: commercial
loans (including agricultural loans), consumer loans, real estate mortgage loans
(residential  and commercial  loans and mortgage loans originated for sale), and
real estate  construction  loans.  At December 31, 2005,  these four  categories
accounted for approximately  10%, 37%, 45%, and 8% of the Bank's loan portfolio,
respectively,  as compared to 12%, 35%,  46%, and 7%, at December 31, 2004.  The
shift  in  the   percentages   was  primarily  due  to  the  Bank's  ability  to
significantly  increase all loan  categories  except  commercial,  financial and
agricultural  during 2005,  which  increased only modestly in 2005. The shift in
percentages  is reflected  in the  Company's  assessment  of the adequacy of the
allowance for loan losses. The increase in consumer loans during 2005 was mainly
due to  increases  in home  equity  lines of credit and  automobile  loans.  The
increase in real estate  mortgage  loans during 2005 was mainly due to increases
in commercial  real estate  mortgage  loans.  The interest rates charged for the
loans made by the Bank vary with the degree of risk,  the size and  maturity  of
the loans, the borrower's relationship with the Bank and prevailing money market
rates indicative of the Bank's cost of funds.

The majority of the Bank's loans are direct loans made to  individuals,  farmers
and  local  businesses.  The Bank  relies  substantially  on  local  promotional
activity and personal  contacts by bank  officers,  directors  and  employees to
compete  with other  financial  institutions.  The Bank makes loans to borrowers
whose applications include a sound purpose, a viable repayment source and a plan
of repayment established at inception and generally backed by a secondary source
of repayment.

At  December  31,  2005  loans,  including  net  deferred  loan  costs,  totaled
$1,385,035,000 which was an 18.1%  ($212,068,000)  increase over the balances at
the end of 2004. Demand for home equity loans and auto loans (both classified as
consumer loans) remained strong throughout 2005. Commercial real estate mortgage
loan  and  construction  loan  activity  was  strong  in  2005.  Commercial  and
agriculture  related loan growth  continued to be relatively  weak in 2005,  and
competition for such loans was high. The average  loan-to-deposit  ratio in 2005
was 88.4% compared to 83.1% in 2004.

At  December  31,  2004  loans,  including  net  deferred  loan  costs,  totaled
$1,172,967,000  which was a 19.4%  ($190,507,000)  increase over the balances at
the end of 2003. Demand for home equity loans and auto loans (both classified as
consumer  loans) were strong  throughout  2004.  Commercial real estate mortgage
loan activity was strong in 2004. Commercial and agriculture related loan growth
continued to be  relatively  weak in 2004,  and  competition  for such loans was
high. The average  loan-to-deposit  ratio in 2004 was 83.1% compared to 72.2% in
2003.

Classified Assets

The  Company  closely  monitors  the  markets in which it  conducts  its lending
operations  and  continues  its strategy to control  exposure to loans with high
credit risk.  Asset reviews are performed  using grading  standards and criteria
similar to those employed by bank regulatory  agencies.  Assets receiving lesser
grades  fall  under  the  "classified  assets"  category,   which  includes  all
nonperforming  assets and potential problem loans, and receive an elevated level
of attention to ensure collection.

The following is a summary of classified assets on the dates indicated  (dollars
in thousands):

Classified  assets,  net of  guarantees  of the U.S.  Government,  including its
agencies and its  government-sponsored  agencies at December 31, 2005, decreased
$6,925,000 (53.7%) to $5,976,000 from $12,901,000 at December 31, 2004.

Nonperforming Assets

Loans on which the accrual of interest has been  discontinued  are designated as
nonaccrual loans. Accrual of interest on loans is generally  discontinued either
when reasonable  doubt exists as to the full,  timely  collection of interest or
principal or when a loan becomes  contractually past due by 90 days or more with
respect  to  interest  or  principal.  When  loans are 90 days past due,  but in
Management's  judgment are well secured and in the process of  collection,  they
may not be classified as nonaccrual. When a loan is placed on nonaccrual status,
all interest  previously  accrued but not collected is reversed.  Income on such
loans is then  recognized only to the extent that cash is received and where the
future  collection  of principal is probable.  Interest  accruals are resumed on
such loans only when they are brought fully current with respect to interest and
principal and when, in the judgment of Management, the loans are estimated to be
fully  collectible as to both principal and interest.  The  reclassification  of
loans as nonaccrual does not  necessarily  reflect  management's  judgment as to
whether they are collectible.

Interest income on nonaccrual loans which would have been recognized  during the
year ended  December 31, 2005,  if all such loans had been current in accordance
with their original terms, totaled $957,000. Interest income actually recognized
on these loans in 2005 was $736,000.

                                      -30-



The  Bank's  policy  is to place  loans 90 days or more  past due on  nonaccrual
status.  In some instances  when a loan is 90 days past due management  does not
place  it on  nonaccrual  status  because  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 30
days.  Loans where the collateral has been  repossessed  are classified as other
real estate owned ("OREO") or, if the collateral is personal property,  the loan
is classified as other assets on the Company's financial statements.

Management considers both the adequacy of the collateral and the other resources
of the  borrower  in  determining  the steps to be taken to  collect  nonaccrual
loans.   Alternatives  that  are  considered  are  foreclosure,   collecting  on
guarantees, restructuring the loan or collection lawsuits.

Allowance for Loan Losses

Credit  risk is inherent in the  business of lending.  As a result,  the Company
maintains  an  allowance  for loan  losses  to  absorb  losses  inherent  in the
Company's loan and lease portfolio.  This is maintained through periodic charges
to earnings.  These charges are shown in the consolidated  income  statements as
provision for loan losses. All specifically identifiable and quantifiable losses
are  immediately  charged off against the allowance.  However,  for a variety of
reasons,  not all losses are immediately known to the Company and, of those that
are known,  the full extent of the loss may not be quantifiable at that point in
time.  The balance of the Company's  allowance for loan losses is meant to be an
estimate of these unknown but probable losses inherent in the portfolio.

For the remainder of this discussion,  "loans" shall include all loans and lease
contracts, which are a part of the Bank's portfolio.

Assessment of the Adequacy of the Allowance for Loan Losses

The Company  formally  assesses  the  adequacy of the  allowance  on a quarterly
basis.  Determination  of the  adequacy is based on ongoing  assessments  of the
probable  risk in the  outstanding  loan and  lease  portfolio,  and to a lesser
extent the Company's loan and lease commitments.  These assessments  include the
periodic  re-grading  of credits  based on changes  in their  individual  credit
characteristics including delinquency,  seasoning,  recent financial performance
of the borrower,  economic  factors,  changes in the interest rate  environment,
growth  of the  portfolio  as a  whole  or by  segment,  and  other  factors  as
warranted.  Loans are initially  graded when  originated.  They are re-graded as
they are renewed, when there is a new loan to the same borrower, when identified
facts demonstrate  heightened risk of nonpayment,  or if they become delinquent.
Re-grading of larger problem loans occurs at least  quarterly.  Confirmation  of
the quality of the grading  process is obtained by  independent  credit  reviews
conducted by consultants specifically hired for this purpose and by various bank
regulatory agencies.

The Company's method for assessing the appropriateness of the allowance includes
specific  allowances for identified problem loans and leases,  formula allowance
factors for pools of credits, and allowances for changing  environmental factors
(e.g.,  interest  rates,  growth,  economic  conditions,  etc.).  Allowances for
identified  problem loans are based on specific analysis of individual  credits.
Allowance  factors for loan pools are based on the  previous 5 years  historical
loss experience by product type.  Allowances for changing  environmental factors
are management's  best estimate of the probable impact these changes have had on
the loan portfolio as a whole.

The Components of the Allowance for Loan Losses

As noted  above,  the  overall  allowance  consists of a specific  allowance,  a
formula  allowance,  and an  allowance  for  environmental  factors.  The  first
component,  the specific  allowance,  results  from the  analysis of  identified
credits that meet management's criteria for specific evaluation. These loans are
reviewed  individually  to  determine  if such  loans are  considered  impaired.
Impaired loans are those where management has concluded that it is probable that
the borrower will be unable to pay all amounts due under the contractual  terms.
Loans specifically reviewed,  including those considered impaired, are evaluated
individually  by  management  for  loss  potential  by  evaluating   sources  of
repayment,  including  collateral as applicable,  and a specified  allowance for
loan losses is established where necessary.

                                      -32-



The second  component,  the formula  allowance,  is an estimate of the  probable
losses that have occurred across the major loan categories in the Company's loan
portfolio. This analysis is based on loan grades by pool and the loss history of
these pools. This analysis covers the Company's entire loan portfolio  including
unused commitments but excludes any loans, which were analyzed  individually and
assigned a specific allowance as discussed above. The total amount allocated for
this component is determined by applying loss estimation  factors to outstanding
loans  and loan  commitments.  The  loss  factors  are  based  primarily  on the
Company's  historical  loss  experience  tracked  over a  five-year  period  and
adjusted as  appropriate  for the input of current  trends and  events.  Because
historical loss  experience  varies for the different  categories of loans,  the
loss  factors  applied to each  category  also differ.  In addition,  there is a
greater  chance that the Company has suffered a loss from a loan that was graded
less than satisfactory than if the loan was last graded satisfactory. Therefore,
for any given category,  a larger loss estimation factor is applied to less than
satisfactory  loans than to those that the Company last graded as  satisfactory.
The resulting formula allowance is the sum of the allocations determined in this
manner.

The third component,  the environmental factor allowance, is a component that is
not  allocated to specific  loans or groups of loans,  but rather is intended to
absorb losses that may not be provided for by the other components.

There are several  primary  reasons that the other  components  discussed  above
might not be  sufficient  to absorb the losses  present in  portfolios,  and the
environmental  factor  allowance  is used to provide  for the  losses  that have
occurred because of them.

The first  reason is that  there are  limitations  to any  credit  risk  grading
process.  The volume of loans makes it  impractical to re-grade every loan every
quarter.  Therefore,  it is possible that some  currently  performing  loans not
recently  graded will not be as strong as their last grading and an insufficient
portion of the  allowance  will have been  allocated  to them.  Grading and loan
review often must be done  without  knowing  whether all  relevant  facts are at
hand.  Troubled  borrowers may  deliberately  or  inadvertently  omit  important
information from reports or conversations  with lending officers regarding their
financial condition and the diminished strength of repayment sources.

The second  reason is that the loss  estimation  factors are based  primarily on
historical loss totals.  As such, the factors may not give sufficient  weight to
such considerations as the current general economic and business conditions that
affect the Company's  borrowers  and specific  industry  conditions  that affect
borrowers in that industry. The factors might also not give sufficient weight to
other  environmental  factors such as changing economic  conditions and interest
rates,  portfolio  growth,  entrance  into new  markets or  products,  and other
characteristics as may be determined by Management.

Specifically,  in assessing how much environmental factor allowance needed to be
provided at December 31, 2005, management considered the following:

      -   with  respect  to  loans  to  the  agriculture  industry,   management
          considered the effects on borrowers of weather conditions and overseas
          market conditions for exported products as well as commodity prices in
          general;

      -   with respect to changes in the interest rate  environment,  management
          considered  the recent  changes in  interest  rates and the  resultant
          economic impact it may have had on borrowers with high leverage and/or
          low profitability; and

      -   with  respect  to loans to  borrowers  in new  markets  and  growth in
          general,  management considered the relatively short seasoning of such
          loans and the lack of experience with such borrowers.

Each of these  considerations  was assigned a factor and applied to a portion or
all of the loan  portfolio.  Since these factors are not derived from experience
and are applied to large non-homogeneous groups of loans, they are available for
use across the portfolio as a whole.

Based on the current conditions of the loan portfolio,  management believes that
the  $16,226,000  allowance  for loan losses at December 31, 2005 is adequate to
absorb probable  losses inherent in the Bank's loan portfolio.  No assurance can
be given,  however, that adverse economic conditions or other circumstances will
not result in increased losses in the portfolio.

Other Real Estate Owned

The other real estate owned (OREO)  balance was $0 at both December 31, 2005 and
2004.  The Bank  disposed of properties  with a value of $932,000 in 2004.  OREO
properties  may  consist of a mixture of land,  single  family  residences,  and
commercial buildings.

Intangible Assets

At  December  31,  2005  and  2004,  the  Bank had  intangible  assets  totaling
$19,926,000 and $20,927,000,  respectively.  The intangible assets resulted from
the Bank's 1997  acquisitions  of certain Wells Fargo branches and Sutter Buttes
Savings  Bank,  the  2003  acquisition  of North  State  National  Bank,  and an
additional  minimum  pension  liability  related to the  Company's  supplemental
retirement plans. Intangible assets at December 31, 2005 and 2004 were comprised
of the following:

Amortization  of  core  deposit   intangible  assets  amounting  to  $1,381,000,
$1,358,000,  and $1,207,000, was recorded in 2005, 2004, and 2003, respectively.
The minimum  pension  liability  intangible  asset is not amortized but adjusted
annually based upon actuarial estimates.

Deposits

Deposits at December 31, 2005 increased  $147,964,000  (11.0%) to $1,496,797,000
over 2004 year-end balances. All categories of deposits except savings increased
in 2005.  Included in the December 31, 2005  certificate  of deposit  balance is
$20,000,000  from the State of California.  The Bank  participates  in a deposit
program  offered by the State of California  whereby the State may make deposits
at the Bank's request subject to collateral and credit  worthiness  constraints.
The negotiated  rates on these State  deposits are generally  favorable to other
wholesale funding sources available to the Bank.

this report for a discussion of  shareholders'  equity and  regulatory  capital,
respectively.  Management  believes  that the  Company's  capital is adequate to
support anticipated  growth, meet the cash dividend  requirements of the Company
and meet the future risk-based capital requirements of the Bank and the Company.

Market Risk Management

Overview.  The goal for  managing the assets and  liabilities  of the Bank is to
maximize shareholder value and earnings while maintaining a high quality balance
sheet  without  exposing  the Bank to undue  interest  rate  risk.  The Board of
Directors  has  overall  responsibility  for the  Company's  interest  rate risk
management  policies.  The Bank has an Asset and Liability  Management Committee
(ALCO) which  establishes and monitors  guidelines to control the sensitivity of
earnings to changes in interest rates.

Asset/Liability  Management.  Activities involved in asset/liability  management
include  but are  not  limited  to  lending,  accepting  and  placing  deposits,
investing in  securities  and issuing  debt.  Interest  rate risk is the primary
market risk associated with asset/liability management.  Sensitivity of earnings
to interest rate changes arises when yields on assets change in a different time
period or in a different  amount from that of interest costs on liabilities.  To
mitigate  interest rate risk, the structure of the balance sheet is managed with
the goal  that  movements  of  interest  rates on  assets  and  liabilities  are
correlated  and  contribute  to earnings  even in periods of  volatile  interest
rates.  The  asset/liability  management  policy sets  limits on the  acceptable
amount of variance in net interest margin, net income and market value of equity
under changing interest environments.  Market value of equity is the net present
value  of  estimated  cash  flows  from  the  Bank's  assets,   liabilities  and
off-balance  sheet  items.  The Bank  uses  simulation  models to  forecast  net
interest margin, net income and market value of equity.

Simulation of net interest  margin,  net income and market value of equity under
various  interest  rate  scenarios is the primary tool used to measure  interest
rate risk. Using computer-modeling  techniques, the Bank is able to estimate the
potential impact of changing  interest rates on net interest margin,  net income
and market value of equity. A balance sheet forecast is prepared using inputs of
actual    loan,     securities    and    interest-bearing     liability    (i.e.
deposits/borrowings) positions as the beginning base.

In the simulation of net interest  margin and net income under various  interest
rate scenarios,  the forecast balance sheet is processed  against seven interest
rate  scenarios.  These  seven  interest  rate  scenarios  include  a flat  rate
scenario,  which assumes  interest  rates are  unchanged in the future,  and six
additional rate ramp scenarios ranging from +300 to -300 basis points around the
flat scenario in 100 basis point  increments.  These ramp scenarios  assume that
interest  rates  increase  or  decrease  evenly  (in a  "ramp"  fashion)  over a
twelve-month period and remain at the new levels beyond twelve months.

                                      -36-



The following table  summarizes the effect on net interest income and net income
due to changing interest rates as measured against a flat rate (no interest rate
change)  scenario.  The simulation  results shown below assume no changes in the
structure of the Company's  balance sheet over the twelve months being  measured
(a "flat"  balance  sheet  scenario),  and that deposit rates will track general
interest rate changes by approximately 50%:

In the  simulation  of  market  value of  equity  under  various  interest  rate
scenarios,  the forecast balance sheet is processed  against seven interest rate
scenarios.  These seven interest rate  scenarios  include the flat rate scenario
described  above,  and six additional rate shock scenarios  ranging from +300 to
-300 basis points around the flat scenario in 100 basis point increments.  These
rate shock scenarios assume that interest rates increase or decrease immediately
(in a "shock" fashion) and remain at the new level in the future.

The  following  table  summarizes  the  effect on market  value of equity due to
changing interest rates as measured against a flat rate (no change) scenario:

     -300 (shock)                                         -

These  results  indicate  that given a "flat"  balance  sheet  scenario,  and if
deposit rates track  general  interest  rate changes by  approximately  50%, the
Company's balance sheet is slightly liability sensitive.  "Liability  sensitive"
implies that  earnings  decrease  when  interest  rates rise,  and increase when
interest rates decrease. The magnitude of all the simulation results noted above
is within the Bank's policy  guidelines.  The asset liability  management policy
limits  aggregate  market risk,  as measured in this  fashion,  to an acceptable
level within the context of risk-return trade-offs.

The simulation  results noted above do not incorporate  any management  actions,
which might moderate the negative  consequences of interest rate deviations.  In
addition, the simulation results noted above contain various assumptions such as
a flat balance sheet, and the rate that deposit interest rates change as general
interest rates change. Therefore, they do not reflect likely actual results, but
serve as conservative estimates of interest rate risk.

As with any method of measuring  interest rate risk,  certain  shortcomings  are
inherent  in the method of  analysis  presented  in the  preceding  tables.  For
example,  although certain of the Bank's assets and liabilities may have similar
maturities  or  repricing  time frames,  they may react in different  degrees to
changes in market interest rates. In addition,  the interest rates on certain of
the Bank's asset and liability categories may precede, or lag behind, changes in
market  interest  rates.  Also,  the actual  rates of  prepayments  on loans and
investments could vary significantly  from the assumptions  utilized in deriving
the results as  presented  in the  preceding  table.  Further,  a change in U.S.
Treasury rates  accompanied by a change in the shape of the treasury yield curve
could result in different estimations from those presented herein.  Accordingly,
the results in the  preceding  tables should not be relied upon as indicative of
actual results in the event of changing market interest rates. Additionally, the
resulting  estimates  of changes in market  value of equity are not  intended to
represent, and should not be construed to represent, estimates of changes in the
underlying value of the Bank.

                                      -37-



Interest rate sensitivity is a function of the repricing  characteristics of the
Bank's  portfolio  of assets  and  liabilities.  One  aspect of these  repricing
characteristics is the time frame within which the  interest-bearing  assets and
liabilities  are  subject to change in  interest  rates  either at  replacement,
repricing  or   maturity.   An  analysis  of  the   repricing   time  frames  of
interest-bearing  assets and  liabilities  is sometimes  called a "gap" analysis
because it shows the gap between assets and liabilities repricing or maturing in
each of a number of periods.  Another aspect of these repricing  characteristics
is the relative magnitude of the repricing for each category of interest earning
asset and  interest-bearing  liability  given various changes in market interest
rates.  Gap analysis gives no indication of the relative  magnitude of repricing
given various changes in interest rates.  Interest rate  sensitivity  management
focuses on the maturity of assets and  liabilities  and their  repricing  during
periods of changes in market interest rates.  Interest rate sensitivity gaps are
measured as the difference  between the volumes of assets and liabilities in the
Bank's current portfolio that are subject to repricing at various time horizons.

The following interest rate sensitivity table shows the Bank's repricing gaps as
of December 31, 2005. In this table transaction deposits,  which may be repriced
at will by the Bank, have been included in the less than 3-month  category.  The
inclusion of all of the transaction  deposits in the less than 3-month repricing
category  causes the Bank to appear  liability  sensitive.  Because the Bank may
reprice its transaction  deposits at will,  transaction  deposits may or may not
reprice  immediately with changes in interest rates. In recent years of moderate
interest  rate  changes  the  Bank's  earnings  have  reacted  as though the gap
position  is  slightly   asset   sensitive   mainly  because  the  magnitude  of
interest-bearing  liability  repricing  has  been  less  than the  magnitude  of
interest-earning asset repricing.  This difference in the magnitude of asset and
liability  repricing is mainly due to the Bank's strong core deposit base, which
although they may be repriced within three months,  historically,  the timing of
their  repricing  has been longer than three  months and the  magnitude of their
repricing has been minimal.

Due to the limitations of gap analysis,  as described  above,  the Bank does not
actively  use gap analysis in managing  interest  rate risk.  Instead,  the Bank
relies on the more  sophisticated  interest rate risk simulation model described
above as its primary tool in measuring and managing interest rate risk.

Liquidity

Liquidity refers to the Bank's ability to provide funds at an acceptable cost to
meet loan demand and deposit  withdrawals,  as well as contingency plans to meet
unanticipated funding needs or loss of funding sources.  These objectives can be
met from  either  the  asset  or  liability  side of the  balance  sheet.  Asset
liquidity sources consist of the repayments and maturities of loans,  selling of
loans,  short-term money market investments,  maturities of securities and sales
of  securities  from the  available-for-sale  portfolio.  These  activities  are
generally  summarized as investing  activities in the Consolidated  Statement of
Cash  Flows.  Net  cash  used  by  investing  activities  totaled  approximately
$199,357,000 in 2005. Increased loan balances were responsible for the major use
of funds in this category.

Liquidity is generated from  liabilities  through  deposit growth and short-term
borrowings.  These  activities  are included under  financing  activities in the
Consolidated  Statement of Cash Flows. In 2005,  financing  activities  provided
funds totaling $192,340,000. Internal deposit growth provided funds amounting to
$147,964,000.  The Bank also had available correspondent banking lines of credit
totaling  $50,000,000 at year-end  2005. In addition,  at December 31, 2005, the
Company had loans and securities  available to pledge towards future  borrowings
from the Federal Home Loan Bank of up to $279,671,000.  As of December 31, 2005,
the Company had $31,390,000 of long-term debt and other  borrowings as described
in  Note 7 of the  consolidated  financial  statements  of the  Company  and the
related  notes at Item 8 of this  report.  While these  sources are  expected to
continue to provide  significant  amounts of funds in the future,  their mix, as
well as the possible use of other  sources,  will depend on future  economic and
market  conditions.  Liquidity  is also  provided or used through the results of
operating   activities.   In  2005,   operating   activities  provided  cash  of
$29,919,000.

The Bank classifies its entire investment portfolio as available for sale (AFS).
The AFS  securities  plus  cash  and  cash  equivalents  in  excess  of  reserve
requirements totaled $342,422,000 at December 31, 2005, which was 18.6% of total
assets at that  time.  This was down from  $347,573,000  and 21.4% at the end of
2004.

$100,000  or more is set  forth  in the  following  table.  These  deposits  are
generally  more rate  sensitive  than other  deposits and,  therefore,  are more
likely to be withdrawn to obtain higher yields elsewhere if available.  The Bank
participates in a program  wherein the State of California  places time deposits
with the Bank at the Bank's  option.  At December 31, 2005,  2004 and 2003,  the
Bank had $20,000,000 of these State deposits.

The maturity distribution and yields of the investment portfolio at December 31,
2005 is presented in the following table. The timing of the maturities indicated
in  the   table   below  is  based  on  final   contractual   maturities.   Most
mortgage-backed  securities return principal throughout their contractual lives.
As such,  the  weighted  average  life of  mortgage-backed  securities  based on
outstanding  principal balance is usually  significantly  shorter than the final
contractual  maturity  indicated  below.  At December 31, 2005,  the Bank had no
held-to-maturity securities.

The  principal  cash  requirements  of the Company are dividends on common stock
when  declared.  The Company is dependent  upon the payment of cash dividends by
the Bank to service its commitments. The Company expects that the cash dividends
paid by the  Bank  to the  Company  will be  sufficient  to  meet  this  payment
schedule.   Dividends   from  the  Bank  are   subject  to  certain   regulatory
restrictions.

Off-Balance Sheet Items

The Bank has certain ongoing commitments under operating and capital leases. See
Note 5 of the financial statements at Item 8 of this report for the terms. These
commitments do not significantly  impact operating  results.  As of December 31,
2005 commitments to extend credit and commitments  related to the Bank's deposit
overdraft  privilege  product were the Bank's only  financial  instruments  with
off-balance  sheet  risk.  The  Bank has not  entered  into  any  contracts  for
financial  derivative   instruments  such  as  futures,   swaps,  options,  etc.
Commitments to extend credit were  $626,490,000 and $445,054,000 at December 31,
2005 and 2004, respectively,  and represent 45.2% of the total loans outstanding
at year-end 2005 versus 38.0% at December 31, 2004.  Commitments  related to the
Bank's deposit overdraft  privilege product totaled  $35,002,000 and $28,815,000
at December 31, 2005 and 2004, respectively.

TRICO BANCSHARES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Years Ended December 31, 2005, 2004 and 2003

Note 1 - Summary of Significant Accounting Policies

Principles of Consolidation
The consolidated  financial  statements include the accounts of the Company, and
its  wholly-owned  subsidiary,  Tri Counties Bank (the "Bank").  All significant
intercompany accounts and transactions have been eliminated in consolidation.

Nature of Operations
The Company  operates 32 branch  offices and 17 in-store  branch  offices in the
California  counties of Butte,  Contra Costa, Del Norte,  Fresno,  Glenn,  Kern,
Lake, Lassen, Madera,  Mendocino,  Merced, Nevada, Placer,  Sacramento,  Shasta,
Siskiyou,  Stanislaus,  Sutter,  Tehama,  Tulare,  Yolo and Yuba.  The Company's
operating policy since its inception has emphasized retail banking.  Most of the
Company's customers are retail customers and small to medium sized businesses.

Use of Estimates in the  Preparation of Financial  Statements The preparation of
financial statements in conformity with accounting principles generally accepted
in the United  States of  America  requires  Management  to make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting  period.  On an on-going basis,  the Company  evaluates its estimates,
including  those  related to the  adequacy  of the  allowance  for loan  losses,
investments,  intangible  assets,  income taxes and  contingencies.  The Company
bases its estimates on historical  experience  and on various other  assumptions
that are believed to be reasonable under the circumstances, the results of which
form the basis for  making  judgments  about the  carrying  values of assets and
liabilities that are not readily apparent from other sources. Actual results may
differ from these  estimates  under  different  assumptions or  conditions.  The
allowance for loan losses,  goodwill and other  intangible  assessments,  income
taxes, and the valuation of mortgage  servicing rights,  are the only accounting
estimates  that   materially   affect  the  Company's   consolidated   financial
statements.

Significant Group Concentration of Credit Risk
The Company grants agribusiness,  commercial, consumer, and residential loans to
customers  located  throughout the northern San Joaquin  Valley,  the Sacramento
Valley  and  northern  mountain  regions  of  California.   The  Company  has  a
diversified  loan  portfolio  within  the  business  segments  located  in  this
geographical area.

Cash and Cash Equivalents
For  purposes  of the  consolidated  statements  of cash  flows,  cash  and cash
equivalents include cash on hand, amounts due from banks and federal funds sold.

Investment Securities
The Company  classifies its debt and marketable  equity  securities  into one of
three  categories:  trading,  available-for-sale  or  held-to-maturity.  Trading
securities  are bought and held  principally  for the  purpose of selling in the
near term.  Held-to-maturity  securities are those  securities which the Company
has the  ability and intent to hold until  maturity.  All other  securities  not
included in trading or held-to-maturity are classified as available-for-sale. In
2005 and 2004,  the Company  did not have any  securities  classified  as either
held-to-maturity or trading.

Available-for-sale  securities are recorded at fair value.  Unrealized gains and
losses,  net of the related tax effect,  on  available-for-sale  securities  are
reported  as a separate  component  of other  accumulated  comprehensive  income
(loss) in shareholders' equity until realized.

Premiums and  discounts  are  amortized or accreted over the life of the related
investment  security  as an  adjustment  to yield using the  effective  interest
method.  Dividend and interest income are recognized when earned. Realized gains
and losses for  securities  are included in earnings  and are derived  using the
specific  identification  method for  determining  the cost of securities  sold.
Unrealized  losses  due to  fluctuations  in fair  value of  securities  held to
maturity  or  available  for sale are  recognized  through  earnings  when it is
determined that an other than temporary decline in value has occurred.

Federal Home Loan Bank Stock
The Bank is a  member  of both  the  Federal  Home  Loan  Bank of San  Francisco
("FHLB"),  and as a condition of membership,  it is required to purchase  stock.
The amount of FHLB stock  required  to be  purchased  is based on the  borrowing
capacity  desired by the Bank.  While  technically  these are considered  equity
securities,  there is no market for the FHLB  stock.  Therefore,  the shares are
considered as restricted  investment  securities.  Such investment is carried at
cost.

                                      -47-



Loans Held for Sale
Loans  originated  and intended for sale in the secondary  market are carried at
the  lower  of  aggregate  cost  or  fair  value,  as  determined  by  aggregate
outstanding  commitments from investors of current investor yield  requirements.
Net unrealized losses are recognized through a valuation allowance by charges to
income. At December 31, 2005 and 2004, the Company had no loans held for sale.

Mortgage  loans held for sale are  generally  sold with the  mortgage  servicing
rights  retained by the Company.  The carrying  value of mortgage  loans sold is
reduced by the cost allocated to the associated mortgage servicing rights. Gains
or losses on sales of  mortgage  loans are  recognized  based on the  difference
between the selling price and the carrying  value of the related  mortgage loans
sold.

Loans
Loans are reported at the principal amount  outstanding,  net of unearned income
and the allowance for loan losses.  Loan  origination  and  commitment  fees and
certain  direct  loan  origination  costs are  deferred,  and the net  amount is
amortized as an adjustment of the related  loan's yield over the estimated  life
of the loan.  Loans on which the accrual of interest has been  discontinued  are
designated  as  nonaccrual  loans.  Accrual of  interest  on loans is  generally
discontinued  either  when  reasonable  doubt  exists  as to  the  full,  timely
collection  of interest or principal or when a loan becomes  contractually  past
due by 90 days or more with respect to interest or principal.  When loans are 90
days past due, but in Management's  judgment are well secured and in the process
of  collection,  they may be  classified  as  accrual.  When a loan is placed on
nonaccrual  status,  all  interest  previously  accrued  but  not  collected  is
reversed.  Income on such loans is then  recognized only to the extent that cash
is received and where the future  collection of principal is probable.  Interest
accruals are resumed on such loans only when they are brought fully current with
respect to interest and principal and when, in the judgment of  Management,  the
loans are estimated to be fully  collectible  as to both principal and interest.
All impaired loans are classified as nonaccrual loans.

Reserve for Unfunded Commitments
The reserve for unfunded  commitments  is  established  through a provision  for
losses - unfunded  commitments charged to noninterest  expense.  The reserve for
unfunded  commitments is an amount that Management  believes will be adequate to
absorb  probable  losses  inherent in  existing  commitments,  including  unused
portions of  revolving  lines of credits  and other  loans,  standby  letters of
credits,  and unused  deposit  account  overdraft  privilege.  The  reserve  for
unfunded  commitments is based on evaluations of the  collectibility,  and prior
loss experience of unfunded commitments. The evaluations take into consideration
such  factors as changes in the nature and size of the loan  portfolio,  overall
loan portfolio quality, loan concentrations,  specific problem loans and related
unfunded  commitments,  and  current  economic  conditions  that may  affect the
borrower's or depositor's ability to pay.

Allowance for Loan Losses
The allowance for loan losses is established through a provision for loan losses
charged to expense. Loans and deposit related overdrafts are charged against the
allowance for loan losses when Management  believes that the  collectibility  of
the  principal  is unlikely  or, with  respect to  consumer  installment  loans,
according to an  established  delinquency  schedule.  The allowance is an amount
that Management  believes will be adequate to absorb probable losses inherent in
existing  loans  and  leases,   based  on  evaluations  of  the  collectibility,
impairment and prior loss experience of loans and leases.  The evaluations  take
into  consideration  such  factors  as  changes  in the  nature  and size of the
portfolio,  overall portfolio  quality,  loan  concentrations,  specific problem
loans, and current economic conditions that may affect the borrower's ability to
pay. The Company defines a loan as impaired when it is probable the Company will
be unable to collect all amounts due according to the  contractual  terms of the
loan  agreement.  Impaired  loans are  measured  based on the  present  value of
expected future cash flows discounted at the loan's original  effective interest
rate. As a practical  expedient,  impairment may be measured based on the loan's
observable  market  price or the fair  value  of the  collateral  if the loan is
collateral  dependent.  When the measure of the  impaired  loan is less than the
recorded  investment in the loan, the impairment is recorded through a valuation
allowance.

Credit  risk is inherent in the  business of lending.  As a result,  the Company
maintains  an  allowance  for loan  losses  to  absorb  losses  inherent  in the
Company's  loan  portfolio.  This is  maintained  through  periodic  charges  to
earnings.  These  charges are shown in the  Consolidated  Income  Statements  as
provision for loan losses. All specifically identifiable and quantifiable losses
are  immediately  charged off against the allowance.  However,  for a variety of
reasons,  not all losses are immediately known to the Company and, of those that
are known,  the full extent of the loss may not be quantifiable at that point in
time.  The balance of the Company's  allowance for loan losses is meant to be an
estimate of these unknown but probable  losses  inherent in the  portfolio.  For
purposes of this discussion, "loans" shall include all loans and lease contracts
that are part of the Company's portfolio.

The Company  formally  assesses  the  adequacy of the  allowance  on a quarterly
basis.  Determination  of the  adequacy is based on ongoing  assessments  of the
probable  risk in the  outstanding  loan  portfolio,  and to a lesser extent the
Company's loan commitments. These assessments include the periodic re-grading of
credits based on changes in their individual  credit  characteristics  including
delinquency,  seasoning,  recent financial performance of the borrower, economic
factors, changes in the interest rate environment,  growth of the portfolio as a
whole or by segment, and other factors as warranted.  Loans are initially graded
when  originated.  They are  re-graded as they are renewed,  when there is a new
loan to the same borrower,  when identified facts demonstrate heightened risk of
nonpayment,  or if they become  delinquent.  Re-grading of larger  problem loans
occur at least quarterly.  Confirmation of the quality of the grading process is
obtained by  independent  credit reviews  conducted by consultants  specifically
hired for this purpose and by various bank regulatory agencies.

                                      -48-



The Company's method for assessing the appropriateness of the allowance for loan
losses and the reserve for unfunded commitments includes specific allowances for
identified problem loans and leases as determined by SFAS 114, formula allowance
factors for pools of credits, and allowances for changing  environmental factors
(e.g., interest rates, growth, economic conditions, etc.). Allowance factors for
loan  pools are based on the  previous 5 years  historical  loss  experience  by
product type.  Allowances  for specific  loans are based on SFAS 114 analysis of
individual   credits.   Allowances  for  changing   environmental   factors  are
Management's  best estimate of the probable impact these changes have had on the
loan portfolio as a whole.

Based on the current conditions of the loan portfolio,  Management believes that
the  allowance for loan losses and the reserve for unfunded  commitments,  which
collectively  stand at  $18,039,000 at December 31, 2005, are adequate to absorb
probable losses  inherent in the Company's loan  portfolio.  No assurance can be
given, however, that adverse economic conditions or other circumstances will not
result in increased losses in the portfolio.

Servicing
Servicing  assets are  recognized  as separate  assets when rights are  acquired
through  purchase or through  sale of  financial  assets.  Generally,  purchased
servicing rights are capitalized at the cost to acquire the rights. For sales of
mortgage  loans, a portion of the cost of  originating  the loan is allocated to
the servicing right based on relative fair value.  Fair value is based on market
prices  for  comparable  mortgage  servicing  contracts,   when  available,   or
alternatively,  is based on a valuation  model that calculates the present value
of estimated  future net  servicing  income.  The valuation  model  incorporates
assumptions  that  market  participants  would  use  in  estimating  future  net
servicing income, such as the cost to service,  the discount rate, the custodial
earnings  rate,  an inflation  rate,  ancillary  income,  prepayment  speeds and
default  rates and losses.  Capitalized  servicing  rights are reported in other
assets and are amortized into non-interest income in proportion to, and over the
period of, the estimated  future  servicing  income of the underlying  financial
assets.

Servicing  assets are evaluated for impairment  based upon the fair value of the
rights as compared to amortized  cost.  Impairment is determined by  stratifying
rights into tranches based on predominant risk characteristics, such as interest
rate, loan type and investor type.  Impairment is recognized through a valuation
allowance for an individual  tranche, to the extent that fair value is less than
the capitalized amount for the tranche. If the Company later determines that all
or a portion of the  impairment  no longer  exists for a particular  tranche,  a
reduction of the allowance may be recorded as an increase to income.

Servicing fee income is recorded for fees earned for servicing  loans.  The fees
are based on a contractual percentage of the outstanding  principal;  or a fixed
amount per loan and are  recorded as income when  earned.  The  amortization  of
mortgage servicing rights is netted against loan servicing fee income.

The following table summarizes the Company's  mortgage servicing rights recorded
in other assets as of December 31, 2005 and 2004.

At December 31, 2005 and 2004, the Company  serviced real estate  mortgage loans
for others of $373 million and $368 million,  respectively. At December 31, 2005
and 2004, the fair value of the Company's  mortgage  servicing rights assets was
$3,673,000 and $3,568,000,  respectively.  The fair value of mortgage  servicing
rights was determined  using a discount rate of 10%,  prepayment  speeds ranging
from 8% to 22%, depending on stratification of the specific servicing right, and
a weighted average default rate of 0%. Based on conditions at December 31, 2005,
estimated  aggregate annual  amortization  expense related to mortgage servicing
rights is expected to be $633,000 in each of the next five years.

Off-Balance Sheet Credit Related Financial Instruments
In the ordinary course of business,  the Company has entered into commitments to
extend credit, including commitments under credit card arrangements,  commercial
letters of credit, and standby letters of credit. Such financial instruments are
recorded when they are funded.

                                      -49-



Premises and Equipment
Land is carried at cost. Buildings and equipment, including those acquired under
capital  lease,   are  stated  at  cost  less   accumulated   depreciation   and
amortization.  Depreciation  and  amortization  expenses are computed  using the
straight-line  method over the estimated  useful lives of the related  assets or
lease terms.  Asset lives range from 3-10 years for  furniture and equipment and
15-40 years for land improvements and buildings.

Foreclosed Assets
Assets acquired  through,  or in lieu of, loan foreclosure are held for sale and
are initially recorded at fair value at the date of foreclosure,  establishing a
new cost basis.  Subsequent to  foreclosure,  management  periodically  performs
valuations  and the assets are carried at the lower of  carrying  amount or fair
value less cost to sell. Revenue and expenses from operations and changes in the
valuation allowance are included in other noninterest expense.

Goodwill and Other  Intangible  Assets  Goodwill  represents the excess of costs
over fair value of assets of businesses acquired.  Goodwill and other intangible
assets  acquired in a purchase  business  combination  and determined to have an
indefinite  useful life are not amortized,  but instead tested for impairment at
least annually. Intangible assets with estimable useful lives are amortized over
their respective  estimated useful lives to their estimated residual values, and
reviewed for impairment.

As of the date of  adoption,  the Company  had  identifiable  intangible  assets
consisting of core deposit premiums and minimum pension liability.  Core deposit
premiums are amortized  using an accelerated  method over a period of ten years.
Intangible  assets related to minimum  pension  liability are adjusted  annually
based upon actuarial estimates.

The following  table  summarizes  the Company's  core deposit  intangibles as of
December 31, 2005 and 2004.

Impairment of Long-Lived Assets and Goodwill
Long-lived  assets,  such as premises and equipment,  and purchased  intangibles
subject to amortization,  are reviewed for impairment whenever events or changes
in  circumstances  indicate  that the  carrying  amount  of an asset  may not be
recoverable.  Recoverability  of  assets  to be held and used is  measured  by a
comparison of the carrying amount of an asset to estimated  undiscounted  future
cash flows expected to be generated by the asset.  If the carrying  amount of an
asset  exceeds  its  estimated  future  cash  flows,  an  impairment  charge  is
recognized  by the amount by which the carrying  amount of the asset exceeds the
fair value of the asset. Assets to be disposed of would be separately  presented
in the balance  sheet and reported at the lower of the  carrying  amount or fair
value  less  costs  to sell,  and are no  longer  depreciated.  The  assets  and
liabilities of a disposed  group  classified as held for sale would be presented
separately in the appropriate asset and liability sections of the balance sheet.

On December 31 of each year,  goodwill is tested for  impairment,  and is tested
for impairment  more  frequently if events and  circumstances  indicate that the
asset might be impaired. An impairment loss is recognized to the extent that the
carrying amount exceeds the asset's fair value.  This  determination  is made at
the  reporting  unit  level  and  consists  of two  steps.  First,  the  Company
determines  the fair value of a reporting  unit and  compares it to its carrying
amount.  Second,  if the  carrying  amount of a reporting  unit exceeds its fair
value, an impairment loss is recognized for any excess of the carrying amount of
the reporting unit's goodwill over the implied fair value of that goodwill.  The
implied fair value of goodwill is determined by allocating the fair value of the
reporting unit in a manner similar to a purchase price allocation.  The residual
fair value after this allocation is the implied fair value of the reporting unit
goodwill.

Income Taxes
The  Company's  accounting  for income taxes is based on an asset and  liability
approach.  The Company  recognizes the amount of taxes payable or refundable for
the current  year,  and deferred tax assets and  liabilities  for the future tax
consequences  that have  been  recognized  in its  financial  statements  or tax
returns.  The  measurement  of  tax  assets  and  liabilities  is  based  on the
provisions of enacted tax laws.

Stock-Based Compensation
The Company  uses the  intrinsic  value  method to account for its stock  option
plans (in accordance with the provisions of Accounting  Principles Board Opinion
No. 25).  Under this method,  compensation  expense is recognized  for awards of
options to purchase shares of common stock to employees under compensatory plans
only if the fair  market  value of the stock at the option  grant date (or other
measurement  date, if later) is greater than the amount the employee must pay to
acquire  the  stock.  Statement  of  Financial  Accounting  Standards  No.  123,
Accounting for Stock-Based Compensation (SFAS 123) permits companies to continue
using the  intrinsic  value  method  or to adopt a fair  value  based  method to
account  for  stock  option  plans.  The fair  value  based  method  results  in
recognizing as expense over the vesting period the fair value of all stock-based
awards on the date of grant.  The  Company  has  elected to  continue to use the
intrinsic value method.

Had  compensation  cost  for the  Company's  option  plans  been  determined  in
accordance  with SFAS 123, the Company's net income and earnings per share would
have been reduced to the pro forma amounts indicated below:

The fair value of each option  grant is estimated on the date of grant using the
Black-Scholes   option   pricing  model  with  the  following   weighted-average
assumptions used for grants in 2005, 2004, and 2003:  risk-free interest rate of
3.90%,  3.39%,  and 2.87%;  expected  dividend  yield of 2.2%,  2.3%,  and 3.3%;
expected life of 6.5 years, 6 years,  and 6 years;  expected  volatility of 21%,
19%, and 27%,  respectively.  The weighted  average  grant date fair value of an
option to purchase one share of common stock granted in 2005, 2004, and 2003 was
$4.30, $3.15, and $4.29, respectively.

The Company adopted SFAS 123R on January 1, 2006 using the modified  prospective
method that  requires  compensation  expense be recorded for all unvested  stock
options at January 1, 2006.  The adoption of SFAS 123R  impacted  the  Company's
consolidated  results of  operations  and  earnings  per share  similarly to the
current pro forma disclosures under SFAS 123.

Earnings Per Share
Basic  earnings per share  represents  income  available to common  shareholders
divided by the  weighted-average  number of common shares outstanding during the
period.  Diluted earnings per share reflects additional common shares that would
have been outstanding if dilutive  potential  common shares had been issued,  as
well as any  adjustments  to income  that would  result from  assumed  issuance.
Potential  common  shares that may be issued by the Company  relate  solely from
outstanding stock options, and are determined using the treasury stock method.

Earnings per share have been computed based on the following:

                                                     Years ended December 31,

There were no options  excluded  from the  computation  of diluted  earnings per
share for the years ended  December  31,  2005,  2004,  and 2003,  respectively,
because the effect of these options was antidilutive.

Comprehensive Income
Accounting principles generally require that recognized revenue, expenses, gains
and losses be  included in net income.  Although  certain  changes in assets and
liabilities,   such  as  unrealized  gains  and  losses  on   available-for-sale
securities,  are reported as a separate  component of the equity  section of the
balance  sheet,   such  items,   along  with  net  income,   are  components  of
comprehensive income.

The  components  of other  comprehensive  income and  related tax effects are as
follows:

Recent Accounting Pronouncements
In December 2004, the Financial  Accounting  Standards  Board (FASB) issued FASB
Statement of Financial Accounting Standards No. 123 (revised 2004),  Share-Based
Payment (SFAS 123R),  which replaces SFAS No. 123,  Accounting  for  Stock-Based
Compensation, (SFAS 123) and supersedes APB Opinion No. 25, Accounting for Stock
Issued to Employees.  SFAS 123R requires all share-based  payments to employees,
including  grants of employee stock  options,  to be recognized in the financial
statements based on their fair values beginning with the first interim reporting
period of the Company's  fiscal year beginning  after June 15, 2005,  with early
adoption encouraged.  The pro forma disclosures  previously permitted under SFAS
123 no longer will be an alternative  to financial  statement  recognition.  The
Company  adopted  SFAS 123R on  January  1, 2006  using a  modified  version  of
prospective  application  ("modified prospective  application").  Under modified
prospective  application,  as it is applicable to the Company, SFAS 123R applies
to new grants and to grants modified, repurchased, or cancelled after January 1,
2006.  Additionally,  compensation  cost for the portion of grants for which the
requisite  service has not been  rendered  (generally  referring  to  non-vested
grants) that are  outstanding  as of January 1, 2006 must be  recognized  as the
remaining  requisite service is rendered during the period of and/or the periods
after the adoption of SFAS 123R. The attribution of compensation  cost for those
earlier grants will be based on the same method and on the same  grant-date fair
values  previously  determined  for  the  pro  forma  disclosures  required  for
companies that did not adopt the fair value  accounting  method for  stock-based
employee compensation.

Based on the stock-based compensation awards outstanding as of December 31, 2005
for which the requisite service was not fully rendered prior to January 1, 2006,
the  Company   expects  to  recognize   total  pre-tax   compensation   cost  of
approximately  $869,000  related to outstanding  stock option  grants,  of which
approximately  $139,000  is expected to be  recognized  in the first  quarter of
2006, in accordance with the accounting requirements of SFAS 123R. Future levels
of  compensation  cost  recognized  related to stock-based  compensation  awards
(including the aforementioned  expected costs during the period of adoption) may
be impacted by new awards and/or modifications, repurchases and cancellations of
existing awards before and after the adoption SFAS 123R.

In May 2005,  the FASB issued FASB Statement of Financial  Accounting  Standards
No. 154,  Accounting Changes and Error Corrections,  (SFAS 154) a Replacement of
APB  Opinion  No. 20 and FASB  Statement  No. 3.  SFAS 154  establishes,  unless
impracticable,  retrospective application as the required method for reporting a
change  in   accounting   principle  in  the  absence  of  explicit   transition
requirements specific to a newly adopted accounting principle.  Previously, most
changes in accounting  principle  were  recognized  by including the  cumulative
effect of changing to the new  accounting  principle in net income of the period
of the  change.  Under  SFAS 154,  retrospective  application  requires  (i) the
cumulative effect of the change to the new accounting principle on periods prior
to those  presented  to be  reflected  in the  carrying  amounts  of assets  and
liabilities  as of  the  beginning  of  the  first  period  presented,  (ii)  an
offsetting  adjustment,  if any, to be made to the  opening  balance of retained
earnings (or other appropriate  components of equity) for that period, and (iii)
financial  statements for each individual  prior period presented to be adjusted
to reflect the direct  period-specific  effects of applying  the new  accounting
principle. Special retroactive application rules apply in situations where it is
impracticable to determine either the period-specific  effects or the cumulative
effect of the change.  Indirect effects of a change in accounting  principle are
required to be reported  in the period in which the  accounting  change is made.
SFAS 154 carries  forward the guidance in APB Opinion 20  "Accounting  Changes,"
requiring  justification  of a change in  accounting  principle  on the basis of
preferability.  SFAS  154 also  carries  forward  without  change  the  guidance
contained  in APB  Opinion  20,  for  reporting  the  correction  of an error in
previously issued financial  statements and for a change in accounting estimate.
SFAS 154 is effective for accounting  changes and  corrections of errors made in
fiscal years beginning after December 15, 2005.

Reclassifications
Certain amounts  previously  reported in the 2004 and 2003 financial  statements
have  been   reclassified   to   conform   to  the  2005   presentation.   These
reclassifications  did not  affect  previously  reported  net  income  or  total
shareholders' equity.

2005 by contractual  maturity are shown below. Actual maturities may differ from
contractual  maturities  because  borrowers may have the right to call or prepay
obligations with or without call or prepayment penalties.  At December 31, 2005,
obligations  of U.S.  government  corporations  and  agencies  with a cost basis
totaling  $214,781,000  consist almost  entirely of  mortgage-backed  securities
whose contractual maturity, or principal repayment, will follow the repayment of
the  underlying  mortgages.  For  purposes of the  following  table,  the entire
outstanding  balance  of  these   mortgage-backed   securities  issued  by  U.S.
government  corporations  and agencies is  categorized  based on final  maturity
date. At December 31, 2005, the Company  estimates the average remaining life of
these  mortgage-backed  securities  issued by U.S.  government  corporations and
agencies to be approximately 3.0 years. Average remaining life is defined as the
time span after which the principal balance has been reduced by half.

Obligations of U.S. government  corporations and agencies: The unrealized losses
on investments in obligations of U.S. government  corporations and agencies were
caused  by  interest  rate  increases.  The  contractual  cash  flows  of  these
securities are guaranteed by U.S.  Government  Sponsored  Entities  (principally
Fannie Mae and Freddie  Mac). It is expected  that the  securities  would not be
settled at a price less than the amortized cost of the  investment.  Because the
decline in fair value is  attributable  to  changes  in  interest  rates and not
credit quality, and because the Company has the ability and intent to hold these
investments until a market price recovery or maturity, these investments are not
considered  other-than-temporarily  impaired.  At  December  31,  2005,  56 debt
securities representing obligations of U.S. government corporations and agencies
had  unrealized  losses with aggregate  depreciation  of 3.3% from the Company's
amortized cost basis.

Obligations  of states and  political  subdivisions:  The  unrealized  losses on
investments in obligations of states and political  subdivisions  were caused by
interest rate increases. It is expected that the securities would not be settled
at a price less than the amortized cost of the  investment.  Because the decline
in fair  value is  attributable  to  changes  in  interest  rates and not credit
quality,  and  because  the  Company  has the  ability  and intent to hold these
investments until a market price recovery or maturity, these investments are not
considered  other-than-temporarily  impaired.  At  December  31,  2005,  4  debt
securities  representing  obligations of states and political  subdivisions  had
unrealized  losses  with  aggregate  depreciation  of 0.8%  from  the  Company's
amortized cost basis.

Corporate debt  securities:  The  investments in corporate debt  securities with
unrealized losses are comprised of variable-rate trust preferred bonds issued by
bank holding  companies that mature in 2027 and 2028.  The unrealized  losses on
corporate debt  securities  were caused by interest rate  increases.  One of the
bank holding  companies  representing  $4,849,000 of the $6,746,000 of corporate
bonds with unrealized  losses are rated investment grade by major outside credit
rating  agencies,  and their credit ratings have not diminished  since the bonds
were purchased by the Company.  The two bank holding companies  representing the
remaining $1,897,000 of bonds are not rated by credit rating agencies.  At least
annually, the Company performs its own analysis of the credit worthiness of each
of the corporate debt issuing  companies in question.  Nothing in those analyses
indicates that the unrealized losses are due to anything other than increases in
interest rates.  Because the decline in fair value is attributable to changes in
interest  rates and not credit  quality,  and because the Company has the intent
and ability to hold these investments until a market price recovery or maturity,
these  investments  are  not  considered   other-than-temporarily  impaired.  At
December  31, 2005,  3 corporate  debt  securities  had  unrealized  losses with
aggregate depreciation of 2.6% from the Company's amortized cost basis.

Loans  classified  as  nonaccrual,  net of  guarantees  of the U.S.  government,
including  its  agencies  and its  government-sponsored  agencies,  amounted  to
approximately $2,961,000,  $4,845,000 and $4,360,000 at December 31, 2005, 2004,
and 2003,  respectively.  These nonaccrual loans were classified as impaired and
are included in the recorded  balance in impaired loans for the respective years
shown below. If interest on those loans had been accrued, such income would have
been approximately  $957,000,  $1,231,000 and $1,071,000 in 2005, 2004 and 2003,

Trust I, to issue trust preferred securities.  Concurrently with the issuance of
the trust preferred  securities,  the trust issued 619 shares of common stock to
the Company for $1,000 per share or an aggregate of $619,000.  In addition,  the
Company  issued a Junior  Subordinated  Debenture  to the Trust in the amount of
$20,619,000.  The terms of the  Junior  Subordinated  Debenture  are  materially
consistent  with the terms of the  trust  preferred  securities  issued by TriCo

offering of 20,000 shares of cumulative  trust preferred  securities for cash in
an  aggregate  amount  of  $20,000,000.   The  trust  preferred  securities  are
mandatorily  redeemable  upon  maturity on October 7, 2033 with an interest rate
that resets  quarterly at three-month  LIBOR plus 3.05%,  or 4.16% for the first

securities  were issued through an  underwriting  syndicate to which the Company
paid underwriting fees of $7.50 per trust preferred  security or an aggregate of
$150,000.  The net proceeds of  $19,850,000  were used to finance the opening of
new branches,  improve bank services and  technology,  repurchase  shares of the
Company's  common stock under its  repurchase  plan and  increase the  Company's
capital. The trust preferred securities have not been and will not be registered
under the Securities  Act of 1933, as amended,  or applicable  state  securities
laws  and were  sold  pursuant  to an  exemption  from  registration  under  the
Securities  Act of 1933.  The trust  preferred  securities may not be offered or
sold in the United States absent  registration  or an applicable  exemption from
the  registration  requirements  of the Securities Act of 1933, as amended,  and

trust  preferred  securities  on or after  July 23,  2009.  The trust  preferred
securities  were issued through an  underwriting  syndicate to which the Company
paid underwriting fees of $2.50 per trust preferred  security or an aggregate of

branches,  improve  bank  services  and  technology,  repurchase  shares  of the
Company's  common stock under its  repurchase  plan and  increase the  Company's

The  Company  has  entered  into  employment  agreements  or change  of  control
agreements with certain officers of the Company providing  severance payments to
the officers in the event of a change in control of the Company and  termination
for other than cause.

The  Company is a  defendant  in legal  actions  arising  from  normal  business
activities.  Management  believes,  after consultation with legal counsel,  that
these  actions  are  without  merit  or that  the  ultimate  liability,  if any,
resulting  from them  will not  materially  affect  the  Company's  consolidated
financial position or results from operations.

Note 10 - Shareholders' Equity

Stock Split
On March 11,  2004,  the  Board of  Directors  of TriCo  Bancshares  approved  a
two-for-one stock split of its common stock. The stock split was effected in the
form of a stock  dividend that entitled each  shareholder of record at the close
of business on April 9, 2004 to receive one additional  share for every share of
TriCo  common  stock held on that  date.  Shares  resulting  from the split were
distributed on April 30, 2004.

Dividends Paid
The  Bank  paid to the  Company  cash  dividends  in the  aggregate  amounts  of
$11,190,000, $3,075,000 and $2,810,000 in 2005, 2004 and 2003, respectively. The
Bank is regulated by the Federal Deposit  Insurance  Corporation  (FDIC) and the
State of California  Department of Financial  Institutions.  California  banking
laws limit the Bank's  ability to pay  dividends  to the lesser of (1)  retained
earnings  or (2)  net  income  for  the  last  three  fiscal  years,  less  cash
distributions  paid during such period.  Under this regulation,  at December 31,
2005, the Bank may pay dividends of $47,054,000.

Shareholders' Rights Plan
On June 25, 2001, the Company  announced that its Board of Directors adopted and
entered  into a  Shareholder  Rights  Plan  designed  to  protect  and  maximize
shareholder  value and to assist the Board of  Directors  in  ensuring  fair and
equitable  benefit to all  shareholders in the event of a hostile bid to acquire
the Company.

The Company  adopted this Rights Plan to protect  stockholders  from coercive or
otherwise unfair takeover  tactics.  In general terms, the Rights Plan imposes a
significant  penalty  upon any person or group that  acquires 15% or more of the
Company's  outstanding  common stock without  approval of the Company's Board of
Directors.  The Rights Plan was not adopted in response to any known  attempt to
acquire control of the Company.

Under the Rights  Plan, a dividend of one  Preferred  Stock  Purchase  Right was
declared  for each  common  share held of record as of the close of  business on
July 10, 2001.  No separate  certificates  evidencing  the Rights will be issued
unless and until they become exercisable.

The Rights  generally  will not become  exercisable  unless an acquiring  entity
accumulates or initiates a tender offer to purchase 15% or more of the Company's
common stock. In that event, each Right will entitle the holder,  other than the
unapproved acquirer and its affiliates,  to purchase either the Company's common
stock or shares in an acquiring entity at one-half of market value.

The Right's initial  exercise price,  which is subject to adjustment,  is $49.00
per Right. The Company's Board of Directors generally will be entitled to redeem
the Rights at a  redemption  price of $.01 per Right until an  acquiring  entity
acquires a 15% position. The Rights expire on July 10, 2011.

Stock Repurchase Plan
On March 11,  2004,  the Board of  Directors  of TriCo  Bancshares  approved  an
increase in the maximum number of shares to be  repurchased  under the Company's
stock  repurchase  plan  originally  announced  on July 31, 2003 from 250,000 to
500,000 effective on April 9, 2004, solely to conform with the two-for-one stock
split noted above. The 250,000 shares originally authorized for repurchase under
this  plan  represented   approximately  3.2%  of  the  Company's  approximately
7,852,000 common shares outstanding as of July 31, 2003. This plan has no stated
expiration date for the repurchases, which may occur from time to time as market
conditions  allow.  As of December 31,  2005,  the Company  repurchased  374,371
shares under this plan as adjusted for the 2-for-1 stock split paid on April 30,
2004, which leaves 125,629 shares available for repurchase under the plan.

                                      -61-



Note 11 - Stock Options

In May 2001,  the Company  adopted the TriCo  Bancshares  2001 Stock Option Plan
(2001 Plan) covering officers,  employees,  directors of, and consultants to the
Company.  Under the 2001  Plan,  the option  price  cannot be less than the fair
market  value of the  Common  Stock at the date of grant  except  in the case of

the  grant  date.   Vesting   schedules  under  the  2001  Plan  are  determined
individually for each grant.

In May 1995,  the Company  adopted the TriCo  Bancshares  1995  Incentive  Stock
Option Plan (1995 Plan) covering key employees.  Under the 1995 Plan, the option
price  cannot be less than the fair market value of the Common Stock at the date
of grant. Options for the 1995 Plan expire on the tenth anniversary of the grant
date. Vesting schedules under the 1995 Plan are determined individually for each
grant.

As of December 31, 2005, options for the purchase of 502,436 and 0 common shares

A deferred tax asset or  liability is  recognized  for the tax  consequences  of
temporary  differences  in the  recognition of revenue and expense for financial
and tax reporting  purposes.  The net change during the year in the deferred tax
asset or liability results in a deferred tax expense or benefit.

Taxes  recorded  directly  to  shareholders'  equity  are  not  included  in the
preceding table.  These taxes (benefits)  relating to changes in minimum pension
liability  amounting to ($155,000) in 2005,  ($155,000) in 2004,  and $27,000 in
2003,  unrealized gains and losses on  available-for-sale  investment securities
amounting to ($2,421,000) in 2005, ($1,327,000) in 2004, and ($461,000) in 2003,
and benefits related to employee stock options of ($425,000) in 2005, ($330,000)
in 2004, and ($440,000) in 2003 were recorded directly to shareholders' equity.

The temporary  differences,  tax effected,  which give rise to the Company's net
deferred tax asset recorded in other assets are as follows as of December 31 for
the years indicated:

The  Company  believes  that a valuation  allowance  is not needed to reduce the
deferred  tax assets as it is more  likely  than not that the  results of future
operations will generate  sufficient  taxable income to realize the deferred tax
assets.

Note 14 - Retirement Plans

401(k) Plan
The Company  sponsors a 401(k) Plan whereby  substantially  all employees age 21
and over with 90 days of service may participate.  Participants may contribute a
portion of their  compensation  subject to certain  limits  based on federal tax
laws.  The Company does not  contribute to the 401(k) Plan.  The Company did not
incur any expenses attributable to the 401(k) Plan during 2005, 2004, and 2003.

Employee Stock Ownership Plan
Substantially  all employees  with at least one year of service are covered by a
discretionary  employee stock ownership plan (ESOP).  Contributions  are made to
the plan at the discretion of the Board of Directors.  Contributions to the plan
totaling  $1,279,000  in 2005,  $1,447,000  in 2004,  and  $975,000  in 2003 are
included in salary expense.  Company shares owned by the ESOP are paid dividends
and included in the  calculation  of earnings per share  exactly as other common
shares outstanding.

Deferred Compensation Plans

The Company has deferred  compensation  plans for directors and key  executives,
which allow directors and key executives designated by the Board of Directors of
the Company to defer a portion of their compensation.  The Company has purchased
insurance on the lives of the  participants  and intends to hold these  policies
until  death  as  a  cost  recovery  of  the  Company's  deferred   compensation
obligations  of  $7,278,000,  and  $6,309,000  at  December  31,  2005 and 2004,
respectively.  Earnings credits on deferred  balances totaling $599,000 in 2005,
$591,000 in 2004, and $465,000 in 2003 are included in noninterest expense.

Supplemental Retirement Plans
The Company has supplemental  retirement plans for directors and key executives.
These  plans are  non-qualified  defined  benefit  plans and are  unsecured  and
unfunded.  The Company has purchased  insurance on the lives of the participants
and  intends  to hold  these  policies  until  death as a cost  recovery  of the
Company's retirement obligations.

The cash  values  of the  insurance  policies  purchased  to fund  the  deferred
compensation  obligations and the retirement  obligations  were  $41,768,000 and
$40,479,000 at December 31, 2005 and 2004, respectively.

The  Company  recorded  in  other  liabilities  an  additional  minimum  pension
liability of $3,197,000 and $2,525,000  related to the  supplemental  retirement
plans as of December 31, 2005 and 2004,  respectively.  These amounts  represent
the amount by which the accumulated  benefit  obligations  for these  retirement
plans  exceeded  the fair value of plan assets plus amounts  previously  accrued
related  to the  plans.  These  additional  liabilities  have been  offset by an
intangible  asset to the  extent of  previously  unrecognized  net  transitional
obligation  and  unrecognized  prior service  costs of each plan.  The amount in
excess of  previously  unrecognized  prior  service  cost and  unrecognized  net
transitional  obligation is recorded as a reduction of  shareholders'  equity in
the amount of $1,072,000 and $935,000,  representing  the after-tax  impact,  at
December 31, 2005 and 2004, respectively.  The accumulated benefit obligation is
recorded in other liabilities.

Note 15 - Related Party Transactions

Certain directors,  officers,  and companies with which they are associated were
customers of, and had banking  transactions with, the Company or the Bank in the
ordinary  course of  business.  It is the  Company's  policy  that all loans and
commitments to lend to officers and directors be made on substantially  the same
terms, including interest rates and collateral,  as those prevailing at the time
for comparable transactions with other borrowers of the Bank.

The following table summarizes the activity in these loans for 2005:

Note 16 - 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  to meet the  financing  needs of its  customers.
These  financial  instruments  include  commitments  to extend  credit,  standby
letters of credit,  and deposit account overdraft  privilege.  Those instruments
involve, to varying degrees, elements of risk in excess of the amount recognized
in the balance  sheet.  The contract  amounts of those  instruments  reflect the
extent of  involvement  the  Company  has in  particular  classes  of  financial
instruments.

The Company's exposure to loss in the event of nonperformance by the other party
to the financial instrument for commitments to extend credit and standby letters
of credit written is represented by the contractual amount of those instruments.
The Company uses the same credit policies in making  commitments and conditional
obligations as it does for on-balance sheet instruments.  The Company's exposure
to loss in the  event of  nonperformance  by the  other  party to the  financial
instrument  for  deposit  account  overdraft  privilege  is  represented  by the
overdraft privilege amount disclosed to the deposit account holder.

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 of one year or less or other  termination
clauses  and may require  payment of a fee.  Since many of the  commitments  are
expected to expire without being drawn upon, the total commitment amounts do not
necessarily  represent  future cash  requirements.  The Company  evaluates  each
customer's credit  worthiness on a case-by-case  basis. The amount of collateral
obtained,  if deemed necessary by the Company upon extension of credit, is based
on Management's  credit evaluation of the customer.  Collateral held varies, but
may include accounts receivable,  inventory,  property,  plant and equipment and
income-producing commercial properties.

Standby letters of credit are conditional  commitments  issued by the Company to
guarantee the performance of a customer to a third party.  Those  guarantees are
primarily issued to support private borrowing arrangements. Most standby letters
of credit are issued for one year or less.  The credit risk  involved in issuing
letters of credit is  essentially  the same as that  involved in extending  loan
facilities to customers. Collateral requirements vary, but in general follow the
requirements for other loan facilities.

Deposit  account  overdraft  privilege  amount  represents the unused  overdraft
privilege  balance  available to the Company's  deposit account holders who have
deposit accounts covered by an overdraft privilege.  The Company has established
an overdraft  privilege for certain of its deposit account  products whereby all
holders of such accounts who bring their accounts to a positive balance at least
once every thirty days receive the overdraft privilege.  The overdraft privilege
allows  depositors  to overdraft  their  deposit  account up to a  predetermined
level. The predetermined  overdraft limit is set by the Company based on account
type.

Note 17 - Disclosure of Fair Value of Financial Instruments

The following  methods and  assumptions  were used to estimate the fair value of
each class of financial  instrument  for which it is practical to estimate  that
value.  Cash and due from banks, fed funds purchased and sold,  accrued interest
receivable  and payable,  and short-term  borrowings  are considered  short-term
instruments. For these short-term instruments their carrying amount approximates
their fair value.

Securities
For all  securities,  fair  values are based on quoted  market  prices or dealer
quotes. See Note 3 for further analysis.

Loans
The fair  value of  variable  rate  loans is the  current  carrying  value.  The
interest rates on these loans are regularly  adjusted to market rates.  The fair
value of other types of fixed rate loans is estimated by discounting  the future
cash flows using current rates at which similar loans would be made to borrowers
with similar credit ratings for the same remaining maturities. The allowance for
loan losses is a reasonable estimate of the valuation allowance needed to adjust
computed fair values for credit quality of certain loans in the portfolio.

Deposit Liabilities and Long-Term Debt
The fair value of demand deposits,  savings  accounts,  and certain money market
deposits is the amount payable on demand at the reporting date.  These values do
not consider the estimated fair value of the Company's core deposit  intangible,
which is a significant unrecognized asset of the Company. The fair value of time
deposits and debt is based on the discounted value of contractual cash flows.

Commitments to Extend Credit and Standby Letters of Credit
The fair value of commitments is estimated  using the fees currently  charged to
enter into similar  agreements,  taking into account the remaining  terms of the
agreements and the present credit  worthiness of the counter parties.  For fixed
rate loan commitments,  fair value also considers the difference between current
levels of interest rates and the committed  rates.  The fair value of letters of
credit is based on fees  currently  charged  for  similar  agreements  or on the
estimated  cost to terminate them or otherwise  settle the  obligation  with the
counter parties at the reporting date.

Fair values for financial  instruments are management's  estimates of the values
at which the  instruments  could be exchanged in a transaction  between  willing
parties.  These estimates are subjective and may vary significantly from amounts
that would be realized in actual  transactions.  In addition,  other significant
assets are not  considered  financial  assets  including,  any mortgage  banking
operations,  deferred tax assets, and premises and equipment.  Further,  the tax
ramifications  related to the realization of the unrealized gains and losses can
have a  significant  effect  on the  fair  value  estimates  and  have  not been
considered in any of these estimates. The estimated fair values of the Company's
financial instruments are as follows:

Note 19 - Regulatory Matters

The Company is subject to various regulatory capital  requirements  administered
by federal banking  agencies.  Failure to meet 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 Company must meet
specific capital guidelines that involve quantitative  measures of the Company's
assets,  liabilities  and certain  off-balance-sheet  items as calculated  under
regulatory   accounting   practices.   The   Company's   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 to  maintain  minimum  amounts and ratios (set forth in the
table below) of total and Tier 1 capital to risk-weighted  assets, and of Tier 1
capital to average assets.  Management  believes,  as of December 31, 2005, that
the Company meets all capital adequacy requirements to which it is subject.

As of December 31, 2005, the most recent  notification from the FDIC categorized
the  Bank  as  well  capitalized  under  the  regulatory  framework  for  prompt
corrective  action. To be categorized as well capitalized the Bank must maintain
minimum total  risk-based,  Tier 1 risk-based and Tier 1 leverage  ratios as set
forth  in the  table  below.  There  are no  conditions  or  events  since  that
notification that Management  believes have changed the institution's  category.

Note 21 - Acquisition

The Company acquired North State National Bank on April 4, 2003. The acquisition
and the related  merger  agreement  dated  October 3, 2002,  was approved by the
California Department of Financial  Institutions,  the Federal Deposit Insurance
Corporation, and the shareholders of North State National Bank on March 4, March
7, and March 19, 2003, respectively. At the time of the acquisition, North State
had total assets of $140 million, investment securities of $41 million, loans of
$76 million,  and deposits of $126 million.  The  acquisition  was accounted for
using the purchase method of accounting.  The amount of goodwill  recorded as of
the merger date,  which  represented the excess of the total purchase price over
the  estimated  fair  value of net  assets  acquired,  was  approximately  $15.5
million.  The Company recorded a core deposit  intangible,  which represents the
excess of the fair value of North State's  deposits over their book value on the
acquisition date, of approximately $3.4 million. This core deposit intangible is
scheduled to be amortized over a seven-year average life.

On April 4, 2003,  under the terms of the merger  agreement,  the  Company  paid
$13,090,057 in cash,  issued 723,512 shares of common stock,  and issued options
to purchase 79,587 shares of common stock at an average  exercise price of $6.22
per share in  exchange  for all of the  1,234,375  common  shares and options to
purchase  79,937 common shares of North State  National Bank  outstanding  as of
April 4, 2003.

The pro forma  financial  information  in the following  table  illustrates  the
combined  operating results of the Company and North State National Bank for the
year ended December 31, 2003 as if the  acquisition of North State National Bank
had  occurred  as of January 1, 2003.  The pro forma  financial  information  is
presented for  informational  purposes and is not necessarily  indicative of the
results of  operations  that would have  occurred if the Company and North State
National Bank had  constituted a single entity as of or January 1, 2003. The pro
forma  financial  information is also not  necessarily  indicative of the future
results of operations of the combined company. In particular, any opportunity to
achieve  certain  cost  savings  as a  result  of the  acquisition  has not been
included in the pro forma financial information.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of TriCo  Bancshares is responsible for  establishing and maintaining
effective  internal  control over  financial  reporting.  Internal  control over
financial  reporting  is a process  designed  to  provide  reasonable  assurance
regarding  the  reliability  of  financial  reporting  and  the  preparation  of
financial  statements for external  purposes in accordance  with U.S.  generally
accepted accounting principles.

Under the supervision and with the  participation  of management,  including the
principal  executive  officer  and  principal  financial  officer,  the  Company
conducted an evaluation of the  effectiveness of internal control over financial
reporting  based on the  framework in Internal  Control -  Integrated  Framework
issued by the Committee of Sponsoring  Organizations of the Treadway Commission.
Based on this  evaluation  under the framework in Internal  Control - Integrated
Framework,  management  of the Company  has  concluded  the  Company  maintained
effective internal control over financial reporting,  as such term is defined in
Securities  Exchange  Act of 1934 Rules  13a-15(f),  as of  December  31,  2005.
Internal control over financial  reporting cannot provide absolute  assurance of
achieving financial reporting objectives because of its inherent limitations.

Internal  control over  financial  reporting is a process  that  involves  human
diligence  and  compliance  and is subject to lapses in judgment and  breakdowns
resulting from human  failures.  Internal  control over financial  reporting can
also be circumvented by collusion or improper  management  override.  Because of
such  limitations,  there  is a risk  that  material  misstatements  may  not be
prevented  or detected  on a timely  basis by internal  control  over  financial
reporting.  However,  these  inherent  limitations  are  known  features  of the
financial  reporting  process.  Therefore,  it is  possible  to design  into the
process safeguards to reduce, though not eliminate, this risk.

Management is also responsible for the preparation and fair  presentation of the
consolidated  financial statements and other financial  information contained in
this report. The accompanying consolidated financial statements were prepared in
conformity with U.S. generally accepted  accounting  principles and include,  as
necessary, best estimates and judgments by management.

KPMG LLP, an  independent  registered  public  accounting  firm, has audited the
Company's  consolidated  financial  statements  as of and  for  the  year  ended
December 31,  2005,  and the  Company's  assertion  as to the  effectiveness  of
internal control over financial  reporting as of December 31, 2005, as stated in
its reports, which are included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders
TriCo Bancshares:


We  have  audited   management's   assessment,   included  in  the  accompanying
Management's  Report on Internal  Control over Financial  Reporting,  that TriCo
Bancshares and subsidiaries (the Company) maintained  effective internal control
over financial reporting as of December 31,  2005, based on criteria established
in Internal  Control-Integrated  Framework issued by the Committee of Sponsoring
Organizations of the Treadway  Commission  (COSO).  The Company's  management is
responsible for maintaining  effective internal control over financial reporting
and for its assessment of the  effectiveness  of internal control over financial
reporting.   Our  responsibility  is  to  express  an  opinion  on  management's
assessment and an opinion on the effectiveness of the Company's internal control
over financial reporting based on our audit.

We conducted  our audit in accordance  with the standards of the Public  Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain  reasonable  assurance  about whether  effective
internal  control  over  financial  reporting  was  maintained  in all  material
respects. Our audit included obtaining an understanding of internal control over
financial reporting,  evaluating management's assessment, testing and evaluating
the design and operating  effectiveness of internal control, and performing such
other  procedures as we considered  necessary in the  circumstances.  We believe
that our audit provides a reasonable basis for our opinion.

A company's  internal control over financial  reporting is a process designed to
provide reasonable  assurance  regarding the reliability of financial  reporting
and the preparation of financial  statements for external purposes in accordance
with generally accepted accounting principles. A company's internal control over
financial  reporting  includes those policies and procedures that (1) pertain to
the  maintenance  of records that, in reasonable  detail,  accurately and fairly
reflect the  transactions  and  dispositions  of the assets of the company;  (2)
provide  reasonable  assurance  that  transactions  are recorded as necessary to
permit preparation of financial statements in accordance with generally accepted
accounting  principles,  and that receipts and  expenditures  of the company are
being made only in accordance with authorizations of management and directors of
the company; and (3) provide reasonable assurance regarding prevention or timely
detection of  unauthorized  acquisition,  use, or  disposition  of the company's
assets that could have a material effect on the financial statements.

Because of its inherent  limitations,  internal control over financial reporting
may not prevent or detect misstatements.  Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become
inadequate  because of changes in  conditions,  or that the degree of compliance
with the policies or procedures may deteriorate.

In our opinion,  management's  assessment that TriCo Bancshares and subsidiaries
maintained   effective   internal   control  over  financial   reporting  as  of
December 31, 2005, is fairly stated, in all material respects, based on criteria
established in Internal Control-Integrated  Framework issued by the Committee of
Sponsoring  Organizations  of  the  Treadway  Commission  (COSO).  Also,  in our
opinion, TriCo Bancshares and subsidiaries maintained, in all material respects,
effective  internal  control over financial  reporting as of December 31,  2005,
based on criteria established in Internal Control-Integrated Framework issued by
the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

We also have  audited,  in accordance  with the standards of the Public  Company
Accounting  Oversight Board (United States),  the consolidated balance sheets of
TriCo  Bancshares and  subsidiaries  as of  December 31,  2005 and 2004, 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,
2005, and our report dated March 7,  2006,  expressed an unqualified  opinion on
those consolidated financial statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


The Board of Directors and Shareholders
TriCo Bancshares:

We have audited the accompanying consolidated balance sheets of TriCo Bancshares
and subsidiaries (the Company) as of December 31, 2005 and 2004, 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,  2005.
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 conducted our audits in accordance  with the standards of the Public  Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion, the consolidated  financial statements referred to above present
fairly, in all material respects, the financial position of TriCo Bancshares and
subsidiaries  as of  December 31,  2005  and  2004,  and the  results  of  their
operations and their cash flows for each of the years in the  three-year  period
ended December 31,  2005, in conformity with U.S. generally accepted  accounting
principles.

We also have  audited,  in accordance  with the standards of the Public  Company
Accounting   Oversight  Board  (United  States),   the  effectiveness  of  TriCo
Bancshares and  subsidiaries'  internal  control over financial  reporting as of
December 31,  2005, based on criteria established in Internal Control-Integrated
Framework  issued by the Committee of Sponsoring  Organizations  of the Treadway
Commission (COSO),  and our report dated March 7,  2006 expressed an unqualified
opinion on management's  assessment of, and the effective operation of, internal
control over financial reporting.

ITEM  9.  CHANGES  IN AND  DISAGREEMENTS  WITH  ACCOUNTANTS  ON  ACCOUNTING  AND
FINANCIAL DISCLOSURE

During 2004 and 2005 there were no changes in the Company's accountants.

ITEM 9A. CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

As of December 31, 2005,  the end of the period covered by this Annual Report on
Form 10-K, the Company's  Chief Executive  Officer and Chief  Financial  Officer
evaluated the effectiveness of the Company's  disclosure controls and procedures
(as defined in Rule 13a-15(e) under the Securities  Exchange Act of 1934). Based
upon that evaluation,  the Company's Chief Executive Officer and Chief Financial
Officer each concluded  that as of December 31, 2005,  the Company's  disclosure
controls and procedures were effective to ensure that the  information  required
to be disclosed by the Company in this Annual  Report on Form 10-K was recorded,
processed,  summarized  and reported  within the time  periods  specified in the
SEC's rules and instructions for Form 10-K.

(b) Management's Report on Internal Control over Financial Reporting

The  Company's  management  is  responsible  for  establishing  and  maintaining
effective  internal  control  over  financial  reporting  (as  defined  in  Rule
13a-15(f) under the Securities  Exchange Act of 1934 as amended).  The Company's
internal control over financial  reporting is under the general oversight of the
Board of  Directors  acting  through  the  Audit  Committee,  which is  composed
entirely  of  independent   directors.   KPMG  LLP,  the  Company's  independent
registered  public  accounting firm, has direct and  unrestricted  access to the
Audit Committee at all times, with no members of management  present, to discuss
its audit and any other matters that have come to its attention  that may affect
the Company's  accounting,  financial reporting or internal controls.  The Audit
Committee meets periodically with management,  internal auditors and KPMG LLP to
determine that each is fulfilling its responsibilities and to support actions to
identify,  measure and control risk and augment  internal control over financial
reporting.  Internal control over financial reporting,  however,  cannot provide
absolute assurance of achieving  financial  reporting  objectives because of its
inherent limitations.

Under the supervision and with the  participation  of management,  including the
Company's  Chief  Executive  Officer and Chief  Financial  Officer,  the Company
conducted an evaluation of the  effectiveness of internal control over financial
reporting as of December 31, 2005 based on the framework in "Internal  Control -
Integrated Framework" issued by the Committee of Sponsoring Organizations of the
Treadway Commission.  Based upon that evaluation,  management concluded that the
Company's internal control over financial reporting was effective as of December
31, 2005.  Management's  report on internal control over financial  reporting is
set forth on page 74 of this  Annual  Report on Form 10-K,  and is  incorporated
herein  by  reference.  Management's  assessment  of  the  effectiveness  of the
Company's  internal  control over  financial  reporting has been audited by KPMG
LLP, an independent  registered public accounting firm, as stated in its report,
which  is set  forth  on page 75 of this  Annual  Report  of Form  10-K,  and is
incorporated herein by reference.

(c) Changes in Internal Control over Financial Reporting

No change in the Company's  internal control over financial  reporting  occurred
during  the  fourth  quarter  of the year  ended  December  31,  2005,  that has
materially affected, or is reasonably likely to materially affect, the Company's
internal control over financial reporting.


ITEM 9B. OTHER INFORMATION

All information  required to be disclosed in a current report on Form 8-K during
the fourth quarter of 2005 was so disclosed.

          necessary to make the statements  made, in light of the  circumstances
          under which such  statements were made, not misleading with respect to

          this annual report;
     4.   The registrant's  other  certifying  officer and I are responsible for
          establishing  and maintaining  disclosure  controls and procedures (as
          defined in Exchange Act Rules 13a-14 and 15d-14) and internal  control
          over financial  reporting (as defined in Exchange Act Rules  13a-15(f)
          and 15d-15(f)) for the registrant and we have:
          a.   Designed such disclosure controls and procedures,  or caused such
               disclosure  controls  and  procedures  to be  designed  under our

               caused such  internal  control  over  financial  reporting  to be
               designed under our supervision,  to provide reasonable  assurance
               regarding  the   reliability  of  financial   reporting  and  the
               preparation  of financial  statements  for  external  purposes in
               accordance with generally accepted accounting principles;
          c.   Evaluated  the  effectiveness  of  the  registrant's   disclosure
               controls  and   procedures  and  presented  in  this  report  our
               conclusions  about the  effectiveness of the disclosure  controls
               and  procedures,  as of the  end of the  period  covered  by this
               report based on such evaluations; and
          d.   Disclosed in this report any change in the registrant's  internal
               control  over  financial   reporting  that  occurred  during  the
               registrant's fourth quarter that has materially  affected,  or is
               reasonably likely to materially affect, the registrant's internal
               control over financial reporting; and
     5.   The registrant's other certifying officer and I have disclosed,  based
          on our most recent  evaluation  of  internal  control  over  financial
          reporting, to the registrant's auditors and the audit committee of the
          registrant's board of directors:
          a.   All  significant  deficiencies  and  material  weaknesses  in the
               design or operation of internal control over financial  reporting
               which are reasonably  likely to adversely affect the registrant's
               ability  to  record,  process,  summarize  and  report  financial
               information; and
          b.   Any fraud,  whether or not material,  that involves management or
               other employees who have a significant  role in the  registrant's
