                          INDEPENDENT AUDITOR'S REPORT



The Board of Directors
  and Shareholders
North State National Bank

     We have audited the accompanying balance sheet of North State National Bank
as of December 31, 2002 and 2001, and the related statements of income,  changes
in  shareholders'  equity and cash flows for each of the years in the three-year
period  ended   December  31,  2002.   These   financial   statements   are  the
responsibility  of the Bank's  management.  Our  responsibility is to express an
opinion on these financial statements based on our audits.

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

     In our opinion,  the financial statements referred to above present fairly,
in all material respects, the financial position of North State National Bank as
of December 31, 2002 and 2001,  and the results of its  operations  and its cash
flows for each of the years in the three-year period ended December 31, 2002, in
conformity with accounting principles generally accepted in the United States of
America.

                          NOTES TO FINANCIAL STATEMENTS

     1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

General

North State National Bank (the "Bank")  commenced  operations on March 15, 1982.
The Bank  operates two  branches and its primary  source of revenue is providing
loans to small businesses, professionals,  agricultural entities and individuals
in the Greater Chico Urban Area.

The  accounting  and  reporting  policies  of the Bank  conform  with  generally
accepted  accounting  principles  and  prevailing  practices  within the banking
industry.

Reclassifications

Certain  reclassifications have been made to prior years' balances to conform to
classifications used in 2002.

Investment Securities

     Investments are classified into the following categories:

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

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

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

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

                                   (Continued)

     1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Loans

Loans are stated at principal balances outstanding and interest is accrued daily
based  upon  outstanding  loan  balances.  However,  when,  in  the  opinion  of
management, loans are considered to be impaired and the future collectibility of
interest  and  principal  is in serious  doubt,  loans are placed on  nonaccrual
status and the accrual of interest income is suspended. Any interest accrued but
unpaid is  charged  against  income.  Payments  received  are  applied to reduce
principal to the extent necessary to ensure collection.  Subsequent  payments on
these loans,  or payments  received on  nonaccrual  loans for which the ultimate
collectibility  of  principal is not in doubt,  are applied  first to earned but
unpaid interest and then to principal.

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

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

Reserve for Loan Losses

The  reserve  for loan losses is  maintained  to provide  for losses  related to
impaired  loans and other  losses  that can be  expected  to occur in the normal
course of  business.  The  reserve  is  determined  based on  estimates  made by
management,  to include  consideration  of the character of the loan  portfolio,
specifically   identified  problem  loans,  potential  losses  inherent  in  the
portfolio taken as a whole and economic conditions in the Bank's service area.

Loans  determined to be impaired or  classified  are  individually  evaluated by
management for specific risk of loss. In addition,  a reserve factor is assigned
to  currently  performing  loans  based  on the  Bank's  historical  experience.
Management   also  computes   specific  and  expected  loss  reserves  for  loan
commitments.  These  estimates are  particularly  susceptible  to changes in the
economic environment and market conditions.

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




     1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Reserve for Loan Losses (Continued)

This reserve is established through a provision for loan losses which is charged
to expense.  Additions  to the reserve are  expected to maintain the adequacy of
the total reserve after loan losses and loan growth. The reserve for loan losses
at December 31, 2002 and 2001,  respectively,  reflects management's estimate of
potential losses in the portfolio.

Other Real Estate

Other real estate includes real estate acquired in full or partial settlement of
loan obligations.  When property is acquired,  any excess of the Bank's recorded
investment  in the loan balance and accrued  interest  income over the estimated
fair  market  value of the  property  is charged  against  the  reserve for loan
losses.  A valuation  allowance for losses on other real estate is maintained to
provide for temporary declines in value. The allowance is established  through a
provision  for losses on other real estate which is included in other  expenses.
Subsequent  gains or  losses on sales or  writedowns  resulting  from  permanent
impairments are recorded in other income or expense as incurred. At December 31,
2002 and 2001, the Bank held no other real estate.

Bank Premises and Equipment

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

Income Taxes

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



     1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Earnings Per Share

Basic earnings per share (EPS), which excludes dilution, is computed by dividing
income available to common shareholders by the weighted-average number of common
shares  outstanding for the period.  Diluted EPS reflects the potential dilution
that could occur if securities or other contracts to issue common stock, such as
stock  options,  result in the  issuance  of common  stock  which  shares in the
earnings of the Bank.  The  treasury  stock method has been applied to determine
the dilutive effect of stock options in computing diluted EPS.

Cash Equivalents

For the  purpose  of the  statement  of cash  flows,  cash  and due  from  banks
interest-bearing  deposits  and  Federal  funds sold are  considered  to be cash
equivalents.  Generally,  interest-bearing  deposits  are held in  money  market
accounts and Federal funds are sold for one day periods.

Use of Estimates

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

Stock-Based Compensation

At December 31, 2002, the Bank has one stock-based  employee  compensation plan,
the North State  National Bank 1995 Stock Option Plan,  which is described  more
fully in Note 8. The Bank  accounts  for this  plan  under the  recognition  and
measurement  principles  of APB Opinion No. 25,  Accounting  for Stock Issued to
Employees,  and related  Interpretations.  No stock-based employee  compensation
cost is reflected in net income,  as all options  granted under this plan had an
exercise price equal to the market value of the  underlying  common stock on the
date of grant.





     1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Stock-Based Compensation (Continued)

No stock  options  were  granted  in 2002 and  2001 and no pro  forma  financial
information  is shown for these years.  Pro forma  adjustments to the Bank's net
earnings  and  earnings  per share are  disclosed  during the years in which the
options become vested and all options vested prior to the beginning of 2001. The
following table illustrates the effect on net earnings and earnings per share if
the Bank had applied the fair value recognition provisions of FASB Statement No.

compensation for the year ended December 31, 2000.

     1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Impact of New Financial Accounting Standards

In April 2002, the Financial  Accounting  Standards Board (FASB) issued SFAS No.
145,  Rescission  of FASB  Statements  No.  4,  44,  and 64,  Amendment  of FASB
Statement No. 13, and Technical Corrections. This Statement rescinds SFAS No. 4,
Reporting Gains and Losses from Extinguishment of Debt, and an amendment of that
Statement,  SFAS No. 64,  Extinguishments  of Debt Made to Satisfy  Sinking-Fund
Requirements.   This  Statement  also  rescinds  SFAS  No.  44,  Accounting  for
Intangible  Assets  of Motor  Carriers.  This  Statement  amends  SFAS  No.  13,
Accounting  for Leases,  to  eliminate  an  inconsistency  between the  required
accounting  for  sale-leaseback  transactions  and the required  accounting  for
certain  lease  modifications  that have  economic  effects  that are similar to
sale-leaseback   transactions.   This   Statement  also  amends  other  existing
authoritative  pronouncements  to make various  technical  corrections,  clarify
meanings,  or  describe  their  applicability  under  changed  conditions.  This
Statement is effective for fiscal years beginning  after May 15, 2002.  Adoption
of this  Statement  is not  expected  to have a  material  effect on the  Bank's
financial statements.

In June 2002, the FASB issued SFAS No. 146, Accounting for Costs Associated with
Exit or Disposal  Activities.  This Statement addresses financial accounting and
reporting for costs  associated  with exit or disposal  activities and nullifies
Emerging  Issues Task Force  (EITF) Issue No. 94-3,  Liability  Recognition  for
Certain  Employee  Termination  Benefits  and  Other  Costs to Exit an  Activity
(including  Certain  Costs  Incurred  in a  Restructuring).  This  Statement  is
effective for exit or disposal  activities  initiated  after  December 31, 2002.
Adoption of this  Statement  is not  expected  to have a material  effect on the
Bank's financial statements.

In October 2002, the FASB issued SFAS No. 147, Acquisitions of Certain Financial
Institutions. This Statement, which addresses financial accounting and reporting
matters for the acquisition of all or part of a financial  institution,  applies
to all such  transactions  except those between two or more mutual  enterprises.
This  Statement  removes  acquisitions  of  financial  institutions,  other than
transactions between two or more mutual enterprises,  from the scope of SFAS No.
72, Accounting for Certain Acquisitions of Banking or Thrift  Institutions,  and
related  interpretations.  This  Statement  requires a financial  institution to
apply SFAS No.  144 and  evaluate  long-term  customer  relationship  intangible
assets (core deposit intangibles) for impairment. Under SFAS No. 72, a financial
institution may have recorded an unidentifiable  intangible asset arising from a
business combination. If certain criteria in SFAS No. 147 are met, the amount of
the  unidentifiable  intangible  asset will be  reclassified  to  goodwill  upon
adoption of this Statement and any amortization amounts that were incurred after
the adoption of SFAS No. 142 must be reversed.  Reclassified goodwill would then
be measured for impairment  under the provisions of SFAS No. 142.  Provisions of
this  Statement are  applicable  on or after  October 1, 2002.  In  management's
opinion,  the adoption of this  Statement did not have a material  effect on the
Bank's financial position or results of operations.




     1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Impact of New Financial Accounting Standards (Continued)

In December  2002,  the FASB issued SFAS No.  148,  Accounting  for  Stock-Based
Compensation--Transition and Disclosure--an amendment of FASB Statement No. 123.
This Statement amends SFAS No. 123, Accounting for Stock-Based Compensation,  to
provide  alternative  methods of transition  for a voluntary  change to the fair
value based method of  accounting  for  stock-based  employee  compensation.  In
addition,  this Statement amends the disclosure  requirements of SFAS No. 123 to
require prominent  disclosures in both annual and interim  financial  statements
about the method of accounting for  stock-based  employee  compensation  and the
effect of the method used on  reported  results.  The  transition  guidance  and
annual  disclosure  provisions  of SFAS No. 148 are  effective  for fiscal years
ending after December 15, 2002. The interim disclosure  provisions are effective
for financial  reporting  containing  financial  statements for interim  periods
beginning   after  December  15,  2002.   Because  the  Bank  accounts  for  the
compensation  cost  associated  with its stock  option plan under the  intrinsic
value method, the alternative  methods of transition will not apply to the Bank.
The additional  disclosure  requirements  of the Statement are included in these
financial  statements.  In management's  opinion, the adoption of this Statement
did not have a material  impact on the Bank's  financial  position or results of
operations.

Financial Instruments With Off-Balance-Sheet Risk

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

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

Financial Instruments With Off-Balance-Sheet Risk (Continued)

The following financial instruments represent off-balance-sheet credit risk:

                                  --------------- ---------------

 Commitments to extend credit        $19,659,000     $19,023,000
 Letters of credit                   $   131,000     $   300,000

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

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

At December 31, 2002, commercial loan commitments represent approximately 83% of
total  commitments.  Approximately  81% of these commercial loan commitments are
unsecured  or secured  by  collateral  other  than first  deeds of trust on real
estate and generally have variable interest rates.  Loan commitments  secured by
residential real estate represent  approximately 7% of total commitments and are
generally secured by property with a loan-to-value  ratio not to exceed 80%. The
majority of real estate loan  commitments  also have  variable  interest  rates.
Unsecured  consumer lines of credit,  generally having variable  interest rates,
represent the remaining 10% of total commitments.

Significant Concentrations of Credit Risk

The Bank grants  commercial,  agricultural,  real estate  mortgage,  real estate
construction and consumer loans to customers throughout Butte County.

At December 31, 2002 and 2001, in  management's  judgment,  a  concentration  of
loans existed in real-estate  related loans. At these dates,  approximately  72%
and 67% of the Bank's loans were real-estate related, respectively.




     7. COMMITMENTS AND CONTINGENCIES (Continued)

Significant Concentrations of Credit Risk (Continued)

Although management believes the loans within these  concentrations have no more
than the normal risk of collectibility, a substantial decline in the performance
of the  economy  in general  or a decline  in real  estate  values in the Bank's
primary   market  area,  in   particular,   could  have  an  adverse  impact  on
collectibility,  increase the level of real-estate related  nonperforming loans,
or have other  adverse  effects  which  alone or in the  aggregate  could have a
material adverse effect on the financial condition of the Bank.

Correspondent Banking Agreements

The Bank  maintains  funds on deposit  with other  federally  insured  financial
institutions under correspondent banking agreements.  Uninsured deposits totaled
$11,188,800 at December 31, 2002.

Federal Reserve Requirements

Banks are  required to maintain  reserves at the Federal  Reserve Bank or in the
form of vault cash  equal to a  percentage  of their  reservable  deposits.  The
reserve  balances  required at  December  31,  2002 and 2001 were  $237,000  and
$722,000.

Legal Proceedings

In the  normal  course of  business,  the Bank  becomes  contingently  liable on
matters  related to  transactions  that are not  reflected  in the  accompanying
financial  statements.  After  reviewing  pending  and  threatened  actions  and
proceedings  with legal  counsel,  management  believes that the outcome of such
actions or proceedings  will not have a material adverse effect on operations or
the financial condition of the Bank.

     8. SHAREHOLDERS' EQUITY

Dividends

Upon  declaration by the Board of Directors,  all shareholders of record will be
entitled to receive dividends. Under applicable Federal laws, the Comptroller of
the  Currency  restricts  the total  dividend  payment of any  national  banking
association  in any  calendar  year to the net income of the year,  as  defined,
combined with the net income for the two  preceding  years,  less  distributions
made to shareholders  during the same three-year  period.  At December 31, 2002,
retained earnings of $4,186,697 were free of such restrictions.

On April 16,  2002,  April 17, 2001 and April 18,  2000,  the Board of Directors
declared $.40,  $.35 and $.25 cash dividends,  respectively,  to shareholders of
record at the close of business on May 1, 2002,  2001 and 2000,  payable June 1,
2002, 2001 and 2000.

Stock Options

On April 19,  1995,  the  shareholders  approved the adoption of the North State
National  Bank 1995 Stock Option Plan. At December 31, 2002,  254,338  shares of
the Bank's common stock were reserved for distribution  under the plan. The plan
includes  both  incentive  options,  which may be granted to full-time  salaried
officers  and  employees of the Bank,  and  nonqualified  options,  which may be
granted to Directors and full-time salaried officers and employees. The price of
all options may not be less than the fair market  value of the stock at the date
the option is granted.  The purchase  price of  exercised  options is payable in
full in cash or with  common  stock  previously  acquired by the  optionee.  All
options  expire on a date  determined by the Board of  Directors,  but not later
than ten years from the date of grant.  All  outstanding  options under the plan
vested immediately upon grant.

the  Office of the  Comptroller  of the  Currency  (OCC).  Failure to meet these
minimum  capital  requirements  can  initiate  certain  mandatory,  and possibly
additional discretionary,  actions by regulators that, if undertaken, could have
a direct  material  effect on the Bank's  financial  statements.  Under  capital
adequacy  guidelines and the regulatory  framework for prompt corrective action,
the Bank  must  meet  specific  capital  guidelines  that  involve  quantitative
measures of the Bank's assets,  liabilities and certain  off-balance-sheet items
as calculated under regulatory accounting practices.  The Bank'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 Bank to  maintain  minimum  amounts  and ratios of total and Tier 1
capital to risk-weighted assets and of Tier 1 capital to average assets. Each of
these  components is defined in the  regulations.  Management  believes that the
Bank met all its capital adequacy requirements as of December 31, 2002 and 2001.

In addition,  the most recent  notification from the OCC 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 below.
There are no  conditions or events since the last  notification  by the OCC that
management believes have changed the Bank's category.

     9. COMPREHENSIVE INCOME

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

     At December 31, 2002, 2001 and 2000, the Bank held securities classified as
     available-for-sale which had unrealized gains as follows:

     10. DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

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

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

The following methods and assumptions were used by the Bank to estimate the fair
value of its financial instruments at December 31, 2002 and 2001:

Cash and cash equivalents: For cash and cash equivalents, the carrying amount is
estimated to be fair value.

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

Loans:  For  variable-rate  loans that reprice  frequently  with no  significant
change in credit risk,  the carrying  amount is estimated to be fair value.  The
fair values for other loans are estimated  using  discounted cash flow analyses,
using interest rates being offered at each reporting date for loans with similar
terms to  borrowers  of  comparable  creditworthiness.  The  carrying  amount of
accrued interest receivable approximates its fair value.

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

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





     10. DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS (Continued)

The estimated fair values of the Bank's financial instruments are as follows:

     14. EMPLOYEE BENEFIT PLAN

The Bank's California  Bankers  Association  Prototype Profit Sharing and Salary
Deferral 401(k) Plan is available to employees meeting certain age and length of
service requirements.  Under the Plan, employees can defer a selected portion of
their annual  compensation and the Bank may match each employee  contribution in
an amount to be determined  annually under a formula established by the Board of
Directors.  During 2002, 2001 and 2000, the Bank's contribution totaled $24,000,
$28,000 and $24,000, respectively.

     15. ACQUISITION AGREEMENT AND PLAN OF MERGER

On October 7, 2002,  the Bank and TriCo  Bancshares  announced  the signing of a
definitive  Acquisition  Agreement and Plan of Merger (the "Agreement") in which
TriCo  Bancshares will acquire all of the common shares and unexercised  options
of the Bank.  The  Agreement has been approved by the Bank's Board of Directors,
shareholders  and bank regulatory  authorities.  The Bank  anticipates  that the
merger will be  completed  on or about April 1, 2003.  The agreed upon  purchase
price, based on an average closing price of $26.12 per share of TriCo Bancshares
common  stock,  is  approximately  $34,000,000  and  consists of cash and common
shares of TriCo Bancshares.





EXHIBIT 99.2

                    Pro Forma Unaudited Financial Information

     The merger will be accounted for under the purchase  method of  accounting.
The method  requires that the purchase price be allocated to the acquired assets
and liabilities of North State on the basis of their estimated fair values as of
the date of the merger.  As a result,  on completion  of the merger,  TriCo will
establish a new  accounting  and reporting  basis for the acquired  assets which
will be reflected in the future consolidated  financial statements of TriCo. The
following pro forma tables present the combined historical  financial statements
of TriCo and North  State,  adjusted to give effect to the merger on a pro forma
purchase  accounting basis. The pro forma condensed  consolidated  balance sheet
gives effect to the merger as if it occurred on December 31, 2002. The pro forma
condensed  consolidated  statements of income give effect to the merger as if it
occurred as of the  beginning of the first period  presented  for the year ended
December  31,  2001  and for the year  ended  December  31,  2002,  and  include
adjustments  directly  attributable  to  the  merger  and  expected  to  have  a
continuing impact on the combined entity.

     We expect to incur  reorganization  expenses  as a result  of  merging  the
companies.  The unaudited pro forma  statements  of income  reflect  anticipated
reorganization  expenses  resulting from the merger. We also anticipate that the
merger will  provide the  combined  company with some  financial  benefits  that
include  reduced  operating  expense  and  opportunities  to earn more  revenue.
However,  we do not reflect any of these anticipated cost savings or benefits in
the pro forma information.  This pro forma financial information is provided for
informational  purposes  only and does not attempt to predict or suggest  future
results.  The pro  forma  information  also  does  not  attempt  to show how the
combined  company would  actually have  performed had TriCo and North State been
combined  throughout those periods.  All adjustments,  consisting of only normal
recurring  adjustments,  necessary  for a  fair  statement  of  results  of  the
unaudited historical interim periods have been included.

The  information in the following  tables are based on the historical  financial
information  of  TriCo  and  North  State.  You  should  carefully  review  this
historical information.
