                                     PART I

1.  BUSINESS

Formation of Bank Holding Company.

     TriCo Bancshares  (hereinafter  the "Company") was  incorporated  under the
laws of the State of  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, a wholly-owned
subsidiary  of the Company was merged  with and into the Bank  resulting  in the
shareholders  of the Bank becoming the  shareholders of the Company and the Bank
becoming  the  wholly-owned  subsidiary  of  the  Company.  (The  merger  of the
wholly-owned  subsidiary  of the  Company  with and  into the Bank is  hereafter
referred to as the  "Reorganization.")  At the time of the  Reorganization,  the
Company became a bank holding company subject to the supervision of the Board of
Governors of the Federal  Reserve System (the "FRB") in accordance with the Bank
Holding  Company  Act of 1956,  as  amended.  The Bank  remains  subject  to the
supervision of the State of California Department of Financial  Institutions and
the Federal Deposit  Insurance  Corporation (the "FDIC").  The Bank currently is
the only  subsidiary  of the Company and the Company has not yet  commenced  any
business operations independent of the Bank.

Provision of Banking  Services.

     The 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.

     The  Bank  engages  in  the  general  commercial  banking  business  in the
California  counties of Butte, Del Norte,  Glenn,  Kern, Lake,  Lassen,  Madera,
Mendocino,  Merced, Nevada, Sacramento,  Shasta, Siskiyou,  Stanislaus,  Sutter,
Tehama,  Tulare, and Yuba. The Bank currently has 30 traditional branches, and 7
in-store  branches.  It opened its first banking office in Chico,  California in
1975, followed by branch offices in Willows, Durham and Orland,  California. The
Bank opened its fifth banking office at an additional location in Chico in 1980.
On March 27,  1981,  the Bank  acquired  the  assets of Shasta  County  Bank and
thereby  acquired  six  additional  offices.  These  offices  are located in the
communities  of Bieber,  Burney,  Cottonwood,  Fall River Mills,  Palo Cedro and
Redding,  California.  On November 7, 1987,  the Bank purchased the deposits and
premises  of the  Yreka  Branch  of  Wells  Fargo  Bank,  thereby  acquiring  an
additional  branch  office.  On August 1, 1988,  the Bank opened a new office in
Chico at East 20th Street and Forest Avenue.  The Bank opened a branch office in
Yuba City on September 10, 1990.  The Bank opened four  supermarket  branches in
1994.  These  supermarket  branches were opened on March 7, March 28, June 6 and
June 13, 1994 in Red Bluff,  Yuba City,  and two in Redding,  respectively.  The
Bank added one conventional branch in Redding through its acquisition of Country
National  Bank on July  21,  1994.  On  November  7,  1995,  the  Bank  opened a
supermarket branch in Chico. In March 1996 the Bank opened its sixth supermarket
branch in Grass Valley. The acquisition of Sutter Buttes Savings Bank in October
1996 added a branch in Marysville.  Loan production  offices were established in
Bakersfield  and  Sacramento in 1996. On February 21, 1997,  the Bank  purchased
nine branches from Wells Fargo Bank,  N.A. The acquired  branches are located in
Crescent City,  Weed, Mt. Shasta,  Susanville,  Covelo,  Middletown,  Patterson,
Gustine and Chowchilla.  This  acquisition  expanded the Bank's market area from
the Sacramento Valley and  intermountain  areas to include parts of the northern
coastal  region and the northern San Joaquin  Valley.  In November 1998 the Bank
converted its Bakersfield and Sacramento loan production offices to full service
branches.  In July 1999, the Bank opened a supermarket branch at Beale Air Force
Base. The Bank opened branch offices in Visalia and Modesto,  during August 1999
and  January  2000,  respectively.  In August of 2000,  the Bank opened its most
recent  branch in Paradise.  The Bank plans on opening  branches in Oroville and
Brentwood in the second quarter of 2002.

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.
The Bank does not offer trust services or international banking services.

     The Bank's  operating  policy since its  inception  has  emphasized  retail
banking.  Most of the  Bank's  customers  are  retail  customers  and  small  to
medium-sized  businesses.  The business of 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 the regions of  California  where its branches  are  located.  At
December  31,  2001,  the  total  of  the  Bank's  consumer   installment  loans
outstanding was $155,046,000  (24%),  the total of commercial loans  outstanding
was   $130,054,000   (20%),  and  the  total  of  real  estate  loans  including
construction  loans of $46,735,000 was  $373,632,000  (56%). 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.

                                      -2-


     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. 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 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 anywhere, anytime access to their accounts.

Other activities.

     In  addition  to the  banking  services  referred  to  above,  pursuant  to
California law, TCB Real Estate  Corporation,  a wholly-owned  subsidiary of the
Bank,  was engaged in limited real estate  investments  until  December 1998. At
that time,  TCB Real  Estate  Corporation  divested  its  remaining  real estate
investments. Such investments consisted of holding certain real property for the
purpose of  development or as income  earning  assets.  The amount of the Bank's
assets  committed  to such  investment  did not  exceed  the total of the Bank's
capital and surplus. In 1996 the FDIC directed the Bank to divest the properties
held by TCB Real Estate  Corporation and to terminate its  operations.  The Bank
and the FDIC agreed to a plan that called for the  divestiture by June 30, 1999.
TCB Real Estate Corporation was dissolved on April 27, 1999.

     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."

Employees.

     At  December  31,  2001,  the Company and the Bank  employed  505  persons,
including five executive officers.  Full time equivalent  employees were 412. 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 specifically,  is highly competitive with respect to both loans and
deposits.  It is dominated by a relatively small number of major banks with many
offices  operating over a wide geographic  area. Among the advantages such major
banks have over the Bank are 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.  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.

     As  a  consequence  of  the  extensive  regulation  of  commercial  banking
activities in the United States,  the business of the Company and its subsidiary
are particularly susceptible to being affected by enactment of federal and state
legislation  which may have the effect of increasing  or decreasing  the cost of
doing business,  modifying  permissible  activities or enhancing the competitive
position of other financial institutions.

     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.

                                      -3-


Regulation and Supervision.

     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 Board of Governors of the Federal  Reserve  System  ("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 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.

     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.

     The Company is subject to the minimum capital requirements of the FRB. As a
result of these requirements,  the growth in assets of the Company is limited by
the amount of its capital accounts as defined by the FRB.  Capital  requirements
may have an affect on  profitability  and the  payment of  distributions  by the
Company.  If the Company 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.  Furthermore,  earnings  may  need to be
retained rather than paid as distributions to shareholders.

     The FRB has adopted  guidelines  utilizing a risk-based  capital structure.
These  guidelines apply on a consolidated  basis to bank holding  companies with
consolidated  assets of $150 million or more.  For bank holding  companies  with
less than  $150  million  in  consolidated  assets,  the  guidelines  apply on a
bank-only  basis  unless the  holding  company is engaged in  non-bank  activity
involving  significant  leverage or has a significant amount of outstanding debt
that is held by the general  public.  The  Company  currently  has  consolidated
assets of more than $150 million; accordingly, the risk-based capital guidelines
apply to the Company on a consolidated basis.

                                      -4-


     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
percent 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 percent 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  percent 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.  As of December 31,
2001,  the Company  must have a minimum  ratio of  qualifying  total  capital to
weighted  risk assets of 8 percent,  of which at least 4 percent  must be in the
form of Tier 1 capital.

     The Federal  regulatory  agencies  have  adopted a minimum  Tier 1 leverage
ratio which is intended to supplement  risk-based  capital  requirements  and to
ensure that all financial institutions,  even those that invest predominantly in
low-risk assets,  continue to maintain a minimum level of Tier 1 capital.  These
regulations provide that a banking  organization's minimum Tier 1 leverage ratio
be  determined  by dividing its Tier 1 capital by its  quarterly  average  total
assets,  less goodwill and certain other  intangible  assets.  Under the current
rules,  the Company is required to maintain a minimum Tier 1 leverage ratio of 4
percent.

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, 2001, the deposit insurance premium rate was $0.0188 per
$100.00 in deposits.  In November  1990,  federal  legislation  was passed which
removed the cap on the amount of deposit insurance  premiums that can be charged
by the  FDIC.  Under  this  legislation,  the FDIC is able to  increase  deposit
insurance  premiums as it sees fit. This could result in a significant  increase
in the  cost of doing  business  for the  Bank in the  future.  The FDIC now has
authority to adjust deposit  insurance  premiums paid by insured banks every six
months.

The  Bank's  Risk-Based  Capital Requirements.

     The Bank is subject to the minimum  capital  requirements of the FDIC. As a
result of these requirements, the growth in assets of the Bank is limited by the
amount of its capital accounts as defined by the FRB.  Capital  requirements may
have an effect on profitability and the payment of dividends on the common stock
of the Bank. If the Bank 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.  Further,  earnings may need to be retained
rather than paid as dividends to the Company.

     Federal banking law requires the federal banking regulators to take "prompt
corrective  action"  with  respect  to banks  that do not meet  minimum  capital
requirements.  In response to this  requirement,  the FDIC  adopted  final rules
based upon the five  capital  tiers  defined by the  Federal  Deposit  Insurance
Corporation  Improvement  Act of 1991  (FDICIA):  well  capitalized,  adequately
capitalized,  under capitalized,  significantly under capitalized and critically
under capitalized.  For example, the FDIC's rules provide that an institution is
"well-capitalized"  if its  total  risk-based  capital  ratio is 10  percent  or
greater,  its Tier 1  risk-based  capital  ratio is 6 percent  or  greater,  its
leverage ratio is 5 percent or greater,  and the institution is not subject to a
capital  directive  or an  enforceable  written  agreement  or order.  A bank is
"adequately  capitalized" if its total risk-based  capital ratio is 8 percent or
greater,  its Tier 1 risk-based  capital ratio is 4 percent or greater,  and its
leverage  ratio is 4 percent or greater (3 percent or greater for certain of the
highest-rated institutions). An institution is "significantly  undercapitalized"
if its  risk-based  capital ratio is less than 6 percent,  its Tier 1 risk-based
capital ratio is less than 3 percent, or its tangible equity (Tier 1 capital) to
total assets is equal to or less than 2 percent. An institution may be deemed to
be in a  capitalization  category  that is lower than is indicated by its actual
capital position if it engages in unsafe or unsound banking practices.

     No  sanctions  apply to  institutions  which  are  "well"  or  "adequately"
capitalized under the prompt corrective  action  requirements.  Undercapitalized
institutions  are required to submit a capital  restoration  plan for  improving
capital.  In order to be accepted,  such plan must include a financial  guaranty
from the  institution's  holding  company  that the  institution  will return to
capital  compliance.  If such a  guarantee  were  deemed to be a  commitment  to
maintain  capital  under the federal  Bankruptcy  Code, a claim for a subsequent
breach of the  obligations  under  such  guarantee  in a  bankruptcy  proceeding
involving the holding  company would be entitled to a priority over  third-party
general   unsecured   creditors   of  the  holding   company.   Undercapitalized
institutions  are  prohibited  from  making  capital   distributions  or  paying
management fees to controlling  persons;  may be subject to growth  limitations;
and  acquisitions,  branching  and  entering  into  new  lines of  business  are
restricted.  Finally,  the  institution's  regulatory  agency has  discretion to
impose  certain  of  the  restrictions  generally  applicable  to  significantly
undercapitalized institutions.

     In the event an institution is deemed to be significantly undercapitalized,
it may be required to: sell stock, merge or be acquired,  restrict  transactions
with affiliates,  restrict interest rates paid on deposits, divest a subsidiary,
or dismiss specified directors or officers. If the institution is a bank holding
company,  it may be  prohibited  from making any capital  distributions  without
prior  approval  of the  FRB and may be  required  to  divest  a  subsidiary.  A
critically  undercapitalized  institution  is generally  prohibited  from making
payments on  subordinated  debt and may not,  without the  approval of the FDIC,
enter into a material transaction other than in the ordinary course of business,
engage in any covered  transaction,  or pay excessive  compensation  or bonuses.
Critically  undercapitalized  institutions  are  subject  to  appointment  of  a
receiver or conservator.

                                      -5-


Bank  Regulation.

     The federal regulatory  agencies are required to adopt  regulations,  which
will  establish  safety  and  soundness  standards  that apply to banks and bank
holding  companies.  These standards must address bank  operations,  management,
asset  quality,  earnings,  stock  valuation and employee  compensation.  A bank
holding  company  or  bank  failing  to meet  established  standards  will  face
mandatory regulatory enforcement action.

     The grounds upon which a conservator or receiver of a bank can be appointed
have been expanded.  For example, a conservator or receiver can be appointed for
a bank that fails to  maintain  minimum  capital  levels  and has no  reasonable
prospect of becoming adequately capitalized.

     Federal  law also  requires,  with some  exception,  that each bank have an
annual  examination  performed by its primary federal  regulatory agency, and an
outside  independent  audit.  The outside audit must  consider  bank  regulatory
compliance in addition to financial statement reporting.

     Federal law also restricts the  acceptance of brokered  deposits by insured
depository  institutions and contains a number of consumer  banking  provisions,
including disclosure  requirements and substantive  contractual limitations with
respect to deposit accounts.

Governmental Monetary  Policies and Economic  Conditions.

     The principal  sources of funds essential to the business of banks and bank
holding  companies are deposits,  stockholders'  equity and borrowed funds.  The
availability of these various sources of funds and other potential sources, such
as  preferred  stock or  commercial  paper,  and the  extent  to which  they are
utilized,  depends on many  factors,  the most  important of which are the FRB's
monetary  policies  and the  relative  costs of  different  types of  funds.  An
important  function of the FRB is to regulate the national supply of bank credit
in  order  to  combat  recession  and  curb  inflationary  pressure.  Among  the
instruments of monetary policy used by the FRB to implement these objections are
open market  operations in United States Government  securities,  changes in the
discount rate on bank borrowings,  and changes in reserve  requirements  against
bank deposits. The monetary policies of the FRB have had a significant effect on
the  operating  results  of  commercial  banks in the past and are  expected  to
continue to do so in the future.  In view of the recent  changes in  regulations
affecting commercial banks and other actions and proposed actions by the federal
government and its monetary and fiscal  authorities,  including proposed changes
in the structure of banking in the United  States,  no prediction can be made as
to future changes in interest rates,  credit  availability,  deposit levels, the
overall  performance of banks  generally or the Company and its  subsidiaries in
particular.

General.

     The  Company  conducts  all of its  business  operations  within  a  single
geographic  area.  The Company is principally  engaged in traditional  community
banking  activities  provided  through its thirty  branches  and seven  in-store
branches located throughout Northern and Central  California.  Community banking
activities  include the Bank's commercial and retail lending,  deposit gathering
and investment and liquidity management activities. In addition to its community
banking services,  the Bank offers investment brokerage and leasing services. In
1998 and  prior,  the  Company  held  investments  in real  estate  through  its
wholly-owned  subsidiary,  TCB Real Estate.  These activities were monitored and
reported by Bank management as separate operating segments.

1Quarterly trading activity has been compiled from NASDAQ trading reports.

Holders
     As of February 12, 2002, there were  approximately  1,754 holders of record
of the Company's Common Stock.

Dividends
     The Company has paid quarterly  dividends since March 1990. On February 12,
2002, the Company  declared a quarterly cash dividend of $0.20 per share payable
on March 29,  2002 to  holders  of record at the close of  business  on March 8,
2002. The Company paid quarterly dividends of $0.20 per share in each quarter of
2001 as well as the second,  third and fourth  quarters  of 2000,  and $0.19 per
share in the first quarter of 2000.
     The holders of Common  Stock of the Company  are  entitled to receive  cash
dividends  when and as declared by the Board of Directors,  out of funds legally
available  therefore,  subject to the  restrictions  set forth in the California
General  Corporation Law (the  "Corporation  Law"). The Corporation Law provides
that  a  corporation  may  make  a  distribution  to  its  shareholders  if  the
corporation's  retained  earnings  equal at least  the  amount  of the  proposed
distribution.
     The  Company,  as sole  shareholder  of the Bank,  is  entitled  to receive
dividends  when and as declared by the Bank's Board of  Directors,  out of funds
legally  available  therefore,  subject  to the  powers  of  the  FDIC  and  the
restrictions set forth in the California  Financial Code (the "Financial Code").
The Financial Code provides that a bank may not make any distributions in excess
of the  lesser  of: (i) the  bank's  retained  earnings,  or (ii) the bank's net
income for the last three  fiscal  years,  less the amount of any  distributions
made by the bank to its shareholders  during such period.  However,  a bank may,
with  the  prior  approval  of  the  California  Superintendent  of  Banks  (the
"Superintendent"),  make a distribution to its shareholders of up to the greater
of (A) the  bank's  retained  earnings,  (B) the  bank's net income for its last
fiscal year,  or (C) the bank's net income for its current  fiscal year.  If the
Superintendent  determines that the shareholders' equity of a bank is inadequate
or that a  distribution  by the  bank to its  shareholders  would be  unsafe  or
unsound,  the  Superintendent may order a bank to refrain from making a proposed
distribution.  The FDIC may also order a bank to refrain  from making a proposed
distribution  when,  in its  opinion,  the payment of such would be an unsafe or
unsound practice. The Bank paid dividends totaling $12,187,000 to the Company in
2001. As of December 31, 2001 and subject to the  limitations  and  restrictions
under  applicable  law, the Bank had funds available for dividends in the amount
of $13,327,000.

                                      -9-


     The  Federal  Reserve Act limits the loans and  advances  that the Bank may
make to its affiliates. For purposes of such Act, the Company is an affiliate of
the Bank.  The Bank may not make any loans,  extensions of credit or advances to
the  Company  if the  aggregate  amount of such  loans,  extensions  of  credit,
advances  and any  repurchase  agreements  and  investments  exceeds  10% of the
capital stock and surplus of the Bank. Any such permitted loan or advance by the
Bank must be secured by  collateral of a type and value set forth in the Federal
Reserve Act.
