                     QUESTIONS AND ANSWERS ABOUT THE MERGER


Q:   Why have you sent me this document?

A:   This document contains important information regarding the proposed merger.
     We urge you to read this  document  carefully,  including  its exhibits and
     attachments.  You may also want to review additional  information described
     in the "Summary" section on page 9.

Q:   Why is Tehama Bancorp being acquired by Humboldt Bancorp in the merger?

A:   We believe that  shareholders  of Tehama Bancorp and Humboldt  Bancorp will
     benefit from the merger  because the  potential  for the  combined  company
     exceeds what each company  could  accomplish  individually.  We believe the
     similar and  complementary  financial  products  and  services  provided by
     Humboldt  Bancorp  and Tehama  Bancorp  in  different  markets in  Northern
     California  will  contribute  to the  future  performance  of the  combined
     company.  We also believe that having more  shareholders  will increase the
     liquidity of the shares of Humboldt  Bancorp  common stock after the merger
     is completed.

Q:   What am I being asked to vote on?

A:   The  merger of Tehama  Bancorp  with  Humboldt  Bancorp.  If the  merger is
     completed,  Tehama Bancorp will cease to exist, and Tehama Bank will become
     a subsidiary of Humboldt Bancorp.

Q:   What will Tehama Bancorp shareholders receive in this transaction?

A:   Each share of Tehama  Bancorp  common stock you own,  except for dissenting
     shares,  will be  converted  into 1.775 shares of Humboldt  Bancorp  common
     stock. Any fractional shares will be paid in cash.

Q:   What do I need to do now?

A:   You need to read this document and then sign your proxy card and mail it to
     Tehama  Bancorp or Humboldt  Bancorp,  as the case may be, in the  enclosed
     return envelope as soon as possible.

Q:   What is Humboldt Bancorp's dividend policy?

A:   Humboldt  Bancorp has never paid any cash  dividends  and does not have any
     present  intention to do so in the near future.  However,  Humboldt Bancorp
     has paid stock dividends in the past and does  anticipate  continuing to do
     so in the future.

Q:   Should I send in my Tehama Bancorp stock certificates now?

A:   No. When the merger is completed, you will receive written instructions for
     exchanging your shares of Tehama Bancorp common stock.

Q:   Will I receive cash if the merger is completed?

A:   Maybe.  Even  though  the  merger  will  occur  through  a stock  for stock
     exchange,  a small  amount  of cash will be paid for  fractional  shares of
     Humboldt Bancorp common stock to be issued in the merger. In addition, cash
     will be paid to  shareholders  of Humboldt  Bancorp and Tehama  Bancorp who
     exercise dissenters' rights.

<PAGE>9

Q:   How will my shares of Humboldt  Bancorp  common  stock be traded  after the
     merger?

A:   Humboldt  Bancorp shares of common stock are listed on the Nasdaq  National
     Market under the symbol "HBEK."

Q:   When is the merger expected to be completed?

A:   The merger is expected to be completed by December 31, 2000.

Q:   Whom should I call with questions?

A:   If you  have  any  questions  about  the  merger  or  other  matters  to be
     considered  at the meeting,  please call William P.  Ellison,  President of
     Tehama  Bancorp,  at (530)  528-3000,  or,  if you are a  Humboldt  Bancorp
     shareholder,  Theodore S. Mason,  President of Humboldt  Bancorp,  at (707)

          Department of Financial Institutions; and

     o    Receipt  of  fairness  opinions  by  Tehama  Bancorp  and by  Humboldt
          Bancorp.

Financial  advisors issue opinions that merger  consideration  is fair (Pages 26
and 32 and Appendices B and C)

     Dain  Rauscher  Wessels has issued a fairness  opinion that states that the
conversion ratio of 1.775 Humboldt Bancorp shares into which each Tehama Bancorp
share  will  be  converted  is  fair,  from  a  financial  standpoint,   to  the
shareholders of Tehama Bancorp. In addition to reimbursement of expenses, Tehama
Bancorp  has  agreed to pay Dain  Rauscher  $75,000  on the date the  merger was
publicly  announced  and a cash  fee  equal to 1.5% of the  market  value of the
aggregate   consideration   paid  in  the  exchange  by  Humboldt  Bancorp  upon
consummation of the merger.

     D.A.  Davidson has issued a fairness  opinion that states that the terms of
the  merger  are fair,  from a  financial  standpoint,  to the  shareholders  of
Humboldt Bancorp. In addition to the reimbursement of expenses, Humboldt Bancorp
has agreed to pay D.A.  Davidson  $35,000 upon its  engagement and an additional
$50,000 upon the issuance of its fairness opinion.

     We encourage you to read these opinions carefully.

The boards expect the merger to be tax free (Page 39)

     Bartel Eng Linn & Schroder  has  issued an opinion as to the  material  tax
consequences  of  the  merger.  The  opinion  states  that  the  Tehama  Bancorp
shareholders  will not  recognize  gain or loss for federal  income tax purposes
unless they receive cash for fractional  shares or dissenting  shares.  Humboldt
Bancorp  shareholders  will not  recognize  gain or loss for federal  income tax
purposes unless they receive cash for dissenting shares.

Interests of Tehama Bancorp  executive officer and directors in the merger (Page
23)

     Upon  completion  of the  merger,  it is  anticipated  that Mr.  William P.
Ellison will  continue as  President of Tehama Bank as a subsidiary  of Humboldt
Bancorp. Further, as part of the merger agreement, Messrs. Koeberer, Fish, Katz,
and Napier will become directors of Humboldt Bancorp.

Appraisal rights in the merger (pages 41, Appendix D)

     If you are a shareholder of Tehama Bancorp, you may dissent from the merger
and  demand  payment in cash  equal to the fair  value of your  shares.  You may
dissent by voting against,  abstaining or not voting in favor of the merger. You
must also  write a letter to Tehama  Bancorp  requesting  the  purchase  of your
dissenting  shares and send the letter so that it is received  within 30 days of
the date of mailing of a notice that will be sent to you announcing the approval
by shareholders of the merger.  Valid dissenting shares of Tehama Bancorp common
stock will not be converted into shares of Humboldt Bancorp common stock.

<PAGE>12

     If you are a shareholder of Humboldt Bancorp,  and holders owning more than
5% of the  outstanding  Humboldt  Bancorp  common stock demand payment for their
shares,  you may dissent from the merger and demand payment in cash equal to the
fair value of your shares. You may dissent by voting against,  abstaining or not
voting in favor of the merger.  You must also write a letter to Humboldt Bancorp
requesting the purchase of your dissenting  shares,  and send the letter so that
it is  received  within 30 days of the date of mailing of a notice  that will be
sent to you announcing the approval by shareholders of the merger.

Accounting treatment (Page 52)

     Humboldt  Bancorp  and  Tehama  Bancorp  will  account  for the merger as a
pooling of  interests.  Pooling of  interests  accounting  treatment  avoids the
creation of goodwill in the merger and allows Humboldt  Bancorp to avoid charges
against future earnings from amortizing  goodwill.  This accounting  method also
means that after the merger,  Humboldt Bancorp will report financial  results as
if Tehama Bancorp had always been combined with Humboldt Bancorp.

                                  RISK FACTORS

     In  addition  to the other  information  we provide in this  document,  you
should carefully  consider the following risks before deciding whether to invest
in our common  stock.  These are not the only risks we face.  Some risks are not
yet known to us and there are others we do not  currently  believe are  material
but could  later turn out to be so.  All of these  could  impair  our  business,
operating results or financial  condition.  In evaluating the risks of investing
in us,  you  should  also  evaluate  the  other  information  set  forth in this
document, including our and Tehama Bancorp's financial statements.

Difficulties  of integrating  Tehama Bank could hurt Humboldt  Bancorp's  future
performance

     The earnings,  financial  condition and prospects of Humboldt Bancorp after
the merger depend in large part on Humboldt  Bancorp's  ability to  successfully
integrate the operations  and  management of Tehama Bank with Humboldt  Bancorp.
Although we believe that we have  experience in managing  growth  through branch
acquisitions,  since we have initiated or acquired three financial  institutions
within two years,  we cannot  guarantee  that  Humboldt  Bancorp will be able to
effectively  and  profitably  integrate the  operations and management of Tehama
Bank.  In  addition,  we cannot  guarantee  that we will be able to realize  any
revenue improvement or cost savings as a result of the merger.

Adverse  performance of combined loan portfolios  could hurt Humboldt  Bancorp's
future performance

     Humboldt  Bancorp's  performance and prospects after the merger are largely
dependent on the performance of the combined loan portfolios of Humboldt Bancorp
and its  subsidiaries  and,  ultimately,  on the  financial  condition  of their
respective borrowers and other customers. The existing loan portfolios of Tehama
Bank and Humboldt Bancorp's  subsidiaries  differ to some extent in the types of
borrowers,  industries  and  credits  represented.  In  addition,  there  may be
differences in the documentation, classifications, credit ratings and management
of the  portfolios.  Failure of Humboldt  Bancorp's  management  to  effectively
manage the combined loan portfolio  could have a material  adverse effect on the
business,  financial  condition and results of  operations  of Humboldt  Bancorp
after the merger.

Humboldt Bancorp is dependent on non-traditional banking income for growth

     Because  of  limited  growth in the  Humboldt-Eureka  area,  a  substantial
portion of our  revenue  is derived  from  non-traditional  banking,  especially
merchant  bankcard  processing.  Noninterest  income comprised 42.4%,  43.6% and
34.7% of total  revenues for the six months ended June 30, 2000, and years ended
December 31, 1999 and December 31, 1998.  We have focused our merchant  bankcard
processing on first-time  merchants and small to  medium-sized  merchants in the
retail,  telephone,  mail order and Internet commerce industries.  Because these
merchants do not have an established business record and are located outside our
geographic  location,  they are a greater  business  risk and they  require more
effort to monitor in the event the merchant  experiences a problem.  A reduction
in revenues from merchant  bankcard  processing  would have an adverse effect on
our income.

Capitol  Thrift  and  Loan is under an  agreement  with the FDIC and  California
Department of Financial Institutions

     Capitol  Thrift  and  Loan is  subject  to an  agreement  with the FDIC and
California  Department  of Financial  Institutions  dated  August 23, 1998.  The
agreement requires that Capitol Thrift and Loan:

     o    develop a plan for the reduction of all classified assets;

     o    develop  specific  strategies  for the  reduction of other real estate
          owned; and

     o    maintain its Tier 1 capital in excess of 8% of adjusted total assets.

<PAGE>14

     At June 30,  2000,  Capitol  Thrift and Loan's  Tier 1 capital was 9.5% and
although we believe  that  Capitol  Thrift and Loan has  addressed  the FDIC and
California  Department of Financial  Institution  concerns,  no assurance can be
given that either the FDIC or California  Department  of Financial  Institutions
will not impose additional restrictions on Capitol Thrift's operations.

Our stock option plan contains an antidilution provision

     Our stock  option plan for  directors,  officers and  employees  contains a
provision which grants  additional  options to the option holder in the event we
issue additional shares. The additional options that may be granted will have an
exercise price equal to the fair market value at the time of grant.  As a result
of this  provision,  option  holders  will  have  the  right to  maintain  their
ownership interest in us. Further,  because of these options,  this may have the
effect  of  impairing  the price of our  common  stock or our  ability  to raise
additional capital at a higher price due to the potential dilutive effect to new
investors.

     Our directors have  terminated  their  antidilution  rights under the stock
options.  Those  directors  had options  representing  approximately  42% of the
outstanding options under the stock option plans.

Possible ownership dilution from options and warrants

     As of  September  30, 2000,  Humboldt  Bancorp had  outstanding  options to
purchase an aggregate of 1,016,603  common shares at a weighted average exercise
price of $6.11 per share, with a range of exercise prices of $1.95 to $14.32 per
share. In addition,  Humboldt  Bancorp had  outstanding  warrants to purchase an
aggregate  of 99,000  shares of common  stock at an  average  exercise  price of
$10.91 per share. Based on current market prices, holders of outstanding options
and  warrants  will be able to  purchase  common  stock at a price less than the
current market price of a share of Humboldt  Bancorp common stock,  resulting in
ownership dilution to the other shareholders.

Our acquisitions and growth may strain our personnel and systems

     We have grown substantially through branch acquisition  activity,  new bank
and branch  openings,  the  introduction  of new product  lines,  and  sustained
increases in loans and  deposits.  Rapid growth has at times put high demands on
our management and personnel,  and has required  increased  expenditures for new
employees, enhanced training, office space, and technology upgrades.

We face strong competition

     In recent years, competition for bank customers, the source of deposits and
loans, has greatly intensified. This competition includes:

     o    large national and super-regional  banks, which have  well-established
          branches and  significant  market share in many of the  communities we
          serve;
     o    finance  companies,   investment  banking  and  brokerage  firms,  and
          insurance companies that offer bank-like products;
     o    credit unions,  which can offer highly  competitive rates on loans and
          deposits   because  they  receive  tax  advantages  not  available  to
          commercial banks;
     o    government-assisted   farm  credit  programs  that  offer  competitive
          agricultural loans; o other community banks, including start-up banks,
          that can  compete  with us for  customers  who desire a high degree of
          personal service;
     o    technology-based  financial  institutions including large national and
          super-regional  banks  offering  on-line  deposit,  bill payment,  and
          mortgage loan application services; and
     o    other financial  institutions  offering merchant  bankcard  processing
          services.

<PAGE>15

     Other existing  single or  multi-branch  community  banks, or new community
bank start-ups, have marketing strategies similar to ours. These other community
banks can open new branches in the communities we serve and compete directly for
customers  who want the high  level of  service  community  banks  offer.  Other
community  banks also  compete for the same  management  personnel  and the same
potential acquisition and merger candidates in Northern California.

     Historically, insurance companies, brokerage firms, credit unions and other
non-bank competitors have less regulation than banks and can be more flexible in
the products  and services  they offer.  Under the  recently  enacted  Financial
Services  Modernization Act of 1999, most separations  between banks,  brokerage
firms and  insurance  companies  are  eliminated,  which is  likely to  increase
competition.  See  "Supervision  and  Regulation  of Humboldt  Bancorp -- Recent
Legislation."

Deterioration of local economic conditions could hurt our profitability

     Our operations are primarily located in Northern California. As a result of
this  geographic  concentration,  our  financial  results  depend  largely  upon
economic  conditions  in these  areas.  Adverse  local  economic  conditions  in
Northern  California  and in  particular,  Eureka,  may have a material  adverse
effect on our financial condition and results of operations.

Loss of key employees could hurt our performance

     The loss of the services of a key  employee,  or the failure to attract and
retain other  qualified  persons,  could have a material  adverse  effect on our
business,  financial  condition  and  results  of  operations.  We  are  heavily
dependent on the services of Theodore S. Mason, Humboldt Bancorp's President and
Chief Executive Officer. The operation and performance of Tehama Bank is heavily
dependent on the services of William P. Ellison,  President and Chief  Executive
Officer.  Mr. Mason's employment contract expires on January 1, 2002, and he has
preliminarily indicated that he intends to retire at that time. Humboldt Bancorp
intends to seek a  replacement  for Mr.  Mason  prior to the  expiration  of his
contract.  We intend to enter into employment  arrangements  with Mr. William P.
Ellison for the continuation of his services for Tehama Bank's  operations.  The
loss of either Mr. Mason or Ellison could  adversely  affect our  operations and
our ability to integrate Tehama Bank into our operations.

Limited  trading market for Humboldt  Bancorp common stock and price  volatility
could make it difficult to sell your shares after the merger

     Our common  stock has been listed on the Nasdaq  National  Market under the
symbol  "HBEK"  since  March 29,  2000.  There is limited  trading in our common
stock,  and  given the  limited  trading  history  of our  common  stock and our
inability  to  predict at what  price  level our common  stock will trade in the
future,  the price of our common stock may fluctuate  widely,  depending on many
factors that may have little to do with  operating  results or intrinsic  worth.
You may encounter delay in selling your shares.

Bancorp  will  cease to exist,  and  Tehama  Bank will  become a  subsidiary  of
Humboldt Bancorp.

Record dates

     Humboldt  Bancorp.  The close of business on  ___________,  2000,  has been
fixed as the  Humboldt  Bancorp  record date for the  determination  of Humboldt
Bancorp shareholders entitled to notice of, and to vote at, the Humboldt Bancorp
meeting.

     Tehama Bancorp. The close of business on ___________,  2000, has been fixed
as the  Tehama  Bancorp  record  date for the  determination  of Tehama  Bancorp

Outstanding Securities and Voting Rights

     Humboldt  Bancorp.  There were _________  shares of Humboldt Bancorp common
stock  outstanding as of the Humboldt  Bancorp record date held by approximately
___ record  holders.  Each holder of Humboldt  Bancorp common stock can cast one
vote for each share of Humboldt  Bancorp  common  stock held as of the  Humboldt
Bancorp record date on any matter  presented for a vote of the  shareholders  at
the Humboldt Bancorp meeting.

     Approval of the merger  requires the  affirmative  vote of the holders of a
majority of the outstanding shares of Humboldt Bancorp common stock.

<PAGE>17

     The effect of broker  nonvotes is that these votes are not counted as being
voted for or against the matter;  however,  these votes are counted for purposes
of  determining  a quorum.  The effect of a vote of  abstention on any matter is
that the vote is not counted as a vote for or against the matter, but is counted
as an abstention.

     Tehama Bancorp.  There were _________ shares of Tehama Bancorp common stock
outstanding  as of the Tehama  Bancorp  record  date held by  approximately  ___
record holders. Each holder of Tehama Bancorp common stock can cast one vote for
each share of Tehama  Bancorp  common stock held as of the Tehama Bancorp record
date on any  matter  presented  for a vote  of the  shareholders  at the  Tehama
Bancorp meeting.

     Approval of the merger requires the  affirmative  vote of a majority of the
outstanding shares of Tehama Bancorp common stock.

     The effect of broker  nonvotes is that these votes are not counted as being
voted for or against the matter;  however,  these votes are counted for purposes
of  determining  a quorum.  The effect of a vote of  abstention on any matter is
that the vote is not counted as a vote for or against the matter, but is counted
as an abstention.

Recommendations of the boards of directors

     Both the  boards of  directors  of  Humboldt  Bancorp  and  Tehama  Bancorp
recommend  that their  respective  shareholders  also vote "FOR" approval of the
merger agreement.

     Humboldt  Bancorp's  directors and affiliates own approximately 9.2% of the
outstanding  shares and have entered into director's  agreements  providing that
they will each vote "FOR" approval of the merger agreement. As a result, holders
owning  40.9% of shares of Humboldt  Bancorp  common stock are needed to approve
the merger agreement.

     Tehama Bancorp directors and affiliates holding  approximately 20.1% of the
outstanding shares have entered into director's  agreements  providing that they
will each vote "FOR"  approval  of the merger  agreement.  As a result,  holders
owning 30.0% of the outstanding shares of Tehama Bancorp common stock are needed
to approve the merger agreement.

Revocability of proxies

     A proxy for use at the  Humboldt  Bancorp  meeting  or the  Tehama  Bancorp
meeting, as the case may be, is enclosed. A shareholder  executing and returning
a proxy may revoke it at any time  before  the vote is taken by filing  with the
Secretary of Humboldt  Bancorp or the Secretary of Tehama  Bancorp,  as the case
may be, an instrument revoking it or a duly executed proxy bearing a later date.
In  addition,  the powers of the  proxyholders  will be  suspended if the person
executing  the proxy is present at the  Humboldt  Bancorp  meeting or the Tehama
Bancorp  meeting,  as the case may be, and elects to vote in person by  advising
the chairman of the Humboldt Bancorp meeting or the Tehama Bancorp  meeting,  as
the case may be, of his or her election to vote in person,  and voting in person
at the Humboldt Bancorp meeting or the Tehama Bancorp  meeting,  as the case may
be.  Subject to revocation or suspension,  all shares  represented by a properly
executed proxy received in time for the Humboldt  Bancorp  meeting or the Tehama
Bancorp  meeting,  as the case may be,  will be  voted  by the  proxyholders  in
accordance  with the  instructions  specified on the proxy. If no directions are
given to the contrary on the proxy,  the shares of Humboldt Bancorp common stock
or Tehama  Bancorp  common stock  represented by each proxy will be voted at the
Humboldt  Bancorp  meeting or the Tehama  Bancorp  meeting,  as the case may be,
"FOR" approval of the merger  agreement.  It is not anticipated that any matters
will be presented at the Humboldt  Bancorp meeting or the Tehama Bancorp meeting
other than as set forth in the respective notices of the meetings.  If, however,
other matters are properly  presented at any of the meetings,  the proxy will be
voted in accordance with the best judgment and discretion of the proxyholders.

<PAGE>18

Cost of Solicitation of Proxies

     Humboldt  Bancorp will pay two-thirds and Tehama Bancorp will pay one-third
of the expenses of preparing and printing this document. It is contemplated that
proxies will be solicited through the mail, but officers,  directors and regular
employees of Humboldt  Bancorp and Tehama Bancorp may solicit  proxies for their
respective meetings personally.  Although there is no formal agreement to do so,
Humboldt  Bancorp and Tehama Bancorp may reimburse  banks,  brokerage houses and
other  custodians,  nominees and  fiduciaries for their  reasonable  expenses in
forwarding  these proxy  materials to their  principals.  In addition,  Humboldt
Bancorp and Tehama  Bancorp may pay for and utilize the services of  individuals
or  companies  not  regularly  employed  by any of them in the  solicitation  of
proxies  for their  respective  meetings if the board of  directors  of Humboldt
Bancorp or Tehama Bancorp determines that this is advisable.

                            DESCRIPTION OF THE MERGER

General

     This section  contains  information  furnished by the board of directors of
Humboldt Bancorp in its solicitation of proxies for the Humboldt Bancorp meeting
to approve the merger  agreement and the board of directors of Tehama Bancorp in
its solicitation of proxies for the Tehama Bancorp meeting to approve the merger
agreement. The merger agreement sets out the terms of the merger.

     Humboldt Bancorp will be the surviving corporation of the merger and Tehama
Bancorp will cease to exist.  As a result of the merger,  Humboldt  Bancorp will
own all the shares of Tehama Bank,  and Tehama Bank will become a subsidiary  of
Humboldt Bancorp.  Upon completion of the merger,  each share of Tehama Bancorp,
other than shares held by shareholders who properly exercise dissenters' rights,
will  convert  into the right to receive  shares of  Humboldt  Bancorp's  common
stock.

     No fractional shares of Humboldt Bancorp common stock will be issued in the
merger.  Tehama  Bancorp  shareholders  will be  entitled  to cash  equal to the
fractional  share  multiplied by the price of the last trade of Humboldt Bancorp
common stock prior to the effective date of the merger.

     A copy of the merger  agreement is attached to this  document as Appendix A
and is incorporated in this document by this reference.

Background and Reasons for the Merger

     Humboldt Bancorp's Analysis.  During the past four years,  Humboldt Bancorp
has been  expanding  its services to the  businesses  and  residents in Northern
California,  including  the  surrounding  counties of  Humboldt,  Mendocino  and
Trinity, and more recently, in Placer County, home of the main office of Capitol
Valley Bank.

     One of the  methods  to expand  Humboldt  Bancorp's  services  in  Northern
California is through the merger of Tehama Bancorp. This possibility was due, to
a great  extent,  to the  familiarity  and past  cooperative  efforts of the two
organizations.  For example,  Humboldt Bancorp and Tehama Bancorp both own a 50%
interest in Bancorp Financial Services, Inc. In addition, Tehama Bank introduced
Humboldt Bank to Merchant Bankcard services. Further, the two organizations have
considered  investment in other businesses  including a proposed investment in a
mortgage  company.  Finally,  the  acquisition  of Tehama  Bancorp  will provide
Humboldt Bancorp with a physical presence in central Northern California through
Tehama  Bank and will unite  Humboldt  Bancorp's  operations  from the  Northern
California  coast to the Central Valley of California.  In light of these common
interests,  in March 2000,  Mr. John Koeberer and Mr. William  Ellison  formally
contacted Mr.  Theodore S. Mason to determine if the parties would be interested
in a transaction. As a result of these brief discussions, the parties executed a
confidentiality  agreement  on March 31,  2000,  and during  early  April  2000,
Humboldt  Bancorp held preliminary  discussions with Tehama Bancorp  regarding a
potential merger of Humboldt Bancorp and Tehama Bancorp. These

<PAGE>19

informal  discussions  were held  between  Theodore  Mason,  Humboldt  Bancorp's
president and chief executive  officer,  and William  Ellison,  Tehama Bancorp's
president and chief  executive  officer.  On April 18, 2000,  D.A.  Davidson was
engaged by Humboldt Bancorp to serve as its financial advisor. During the course
of negotiations, Humboldt Bancorp's board of directors consulted with respective
senior management and its financial advisor, D.A. Davidson, as well as its legal
counsel. Continuing considerations were retaining employees,  ensuring that each
organization's   subsidiaries   maintained   their  identities  and  competitive
advantages in their local  marketplaces,  and that the transaction be neutral to
accretive for Humboldt Bancorp shareholders in 2001.

     Over the course of these  negotiations and discussions,  Humboldt Bancorp's
board of  directors  and senior  management  determined  that the  merger  might
provide the following opportunities:

     o    Expansion  of  Humboldt   Bancorp's   lending  and  deposit  gathering
          activities by acquiring Tehama Bank;

     o    Improved  earnings  through  operating  efficiencies  and economies of
          scale;

     o    Further diversity of Humboldt Bancorp's asset base;

     o    Expansion  into new areas of Northern  California,  including  Tehama,
          Butte, Glenn, and Shasta Counties;

     o    Enhancement of services and benefits to the customer base;

     o    Expertise  and strength  represented  on the Tehama  Bancorp  board of
          directors;

     o    Retention,  to the greatest degree possible,  of qualified,  dedicated
          staff and management; and

     o    That the merger will be accounted  for as a pooling of  interests  for
          accounting and financial reporting purposes which accounting treatment
          is anticipated to disappear.

     The Humboldt  Bancorp  board of directors  also  considered  the  potential
problems  resulting from management's span of control,  the complexity of a data
processing  conversion,  and the inability to effectively combine the operations
of  Humboldt  Bancorp  and Tehama  Bank.  Meetings  between  Humboldt  Bancorp's
Executive  Committee  and  Tehama  Bancorp's  senior  management  and  board  of
directors   brought  out  the  fact  that  the  two   organizations  had  worked
successfully  together on past projects,  such as the joint ownership of Bancorp
Financial  Services and that the two entities share similar banking and customer
attention philosophies.

     At the board of directors' meeting approving the merger on August 17, 2000,
Humboldt  Bancorp's  financial  advisor  orally  presented  its  analysis.   The
following material factors were considered at the meeting:

     o    The  economic  conditions  and  prospects  for the  markets  in  which
          Humboldt Bancorp operates,  and competitive pressures in the financial
          services industry in general and the banking industry in particular;

     o    The  enhancement of Humboldt  Bancorp's  competitiveness  and Humboldt
          Bancorp's ability to serve its customers, depositors, creditors, other
          constituents and the communities in which Humboldt Bancorp operates as
          a result of a business combination with Tehama Bancorp;

     o    Information  concerning  the business,  results of  operations,  asset
          quality and financial  condition of Humboldt  Bancorp on a stand-alone
          basis and on a combined  basis  with  Tehama  Bancorp,  as well as the
          future growth prospects following the merger;

<PAGE>20

     o    The cost  savings in  operations,  which the  management  of  Humboldt
          Bancorp believes may be achieved as a result of the merger;

     o    An assessment  that the investment  community would react favorably to
          the  acquisition,  and that, in the current  economic  environment,  a
          Humboldt  Bancorp  common  stock   acquisition  is  most  economically
          advantageous to Humboldt Bancorp's shareholders when compared to other
          alternatives,  like  formation  of a new  bank  or  additional  branch
          acquisitions;

     o    The  terms  and  conditions  of  the  merger   agreement  and  related
          agreements;

     o    The makeup and responsibilities of the combined board of directors;

     o    The  potential  downside  of the  merger.  This  was  principally  the
          challenge  of merging two  different  entities  into one  well-managed
          institution; and

     o    Humboldt  Bancorp's  financial  advisor's  analysis  of the  financial
          condition, results of operations, business prospects and stock prices,
          and a  comparison  of  Tehama  Bank  and  Tehama  Bancorp  with  other
          California banks and bank holding companies in Northern California.

     Humboldt  Bancorp's  board of  directors  and  management  believe that the
potential  issuance of additional  shares of Humboldt  Bancorp common stock will
increase the  liquidity of Humboldt  Bancorp  common stock.  Humboldt  Bancorp's
board of directors and management  also believe the merger will be beneficial to
shareholders  because of cost savings  resulting  from the  combination  of data
processing,  reduction of professional  fees,  reduction in personnel costs, and
other non-interest expenses.

     The above  discussion  of the factors  considered  by the Humboldt  Bancorp
board of directors is not intended to be exhaustive.  In view of the variety and
nature of the factors  considered,  the Humboldt  Bancorp board of directors did
not find it  practicable  to assign  relative  weights to the  specific  factors
considered in reaching its decision.

     Tehama  Bancorp's  Analysis.  At various  times during  1999,  the board of
directors of Tehama Bancorp had discussions regarding the state of the financial
services  industry and the ongoing  consolidation of the banking  industry.  The
board of directors  discussed at length  Tehama  Bank's  future,  including  its
previous position of remaining independent,  its ability to grow, its ability to
attract and retain  personnel,  the potential changes in the manner of providing
and  delivering  services to its  customers  and the usage of and  investment in
technology to do so, and the ability to continue to increase shareholder value.

     While some of these  discussions  were quite general,  they evolved into an
exploration  of the  alternatives  available  to Tehama  Bancorp and, in certain
instances,  informal discussions about the possibility of a business combination
took place.  At its fall retreat in October  1999,  the board of directors  held
general  discussions  regarding various strategic options,  including  remaining
independent,   forming  a  strategic   partnership  with  a  similar   financial
institution,  merging with another financial institution or selling the company.
The board of directors  authorized  William P. Ellison,  the President and Chief
Executive  Officer of Tehama  Bancorp,  to explore  these  options  and  develop
recommendations to be presented to the board.

     During this time, several alternatives were informally evaluated, including
a merger  with one or more area  banks  and/or  the  acquisition  of one or more
banks.  This process included informal  discussions  between William Ellison and
Theodore  Mason,  President  and Chief  Executive  Officer of Humboldt  Bancorp,
regarding a potential merger of the two companies in light of the familiarity of
each entity with the operations,  management  philosophy and strategic vision of
the  other.  This  familiarity  was  based in part on the two  companies'  joint
investment in 1997 in Bancorp Financial Services.

     In March 2000, Tehama Bancorp invited Dain Rauscher to attend the March 16,
2000,  Tehama Bancorp board of directors  meeting and make a presentation to the
Tehama  Bancorp  board of directors  regarding a potential  merger with Humboldt
Bancorp and how such a merger might be structured.  At that meeting,  the Tehama
Bancorp board  authorized  Mr.  Ellison to sign an  engagement  letter with Dain
Rauscher, which was formally executed on April 4, 2000.

     During  April  through  July 2000,  Humboldt  Bancorp and Tehama  Bancorp's
respective  investment  advisors  held  preliminary  discussions  regarding  the
structure and price of the proposed  merger.  On July 24, 2000, Mr. Mason made a
presentation  to Tehama  Bancorp's  board of  directors  on the  activities  and
strategy of Humboldt Bancorp. At this meeting,  Mr. Mason presented a term sheet
outlining  the  basic  terms of a  proposed  merger  agreement.  Tehama  Bancorp
authorized Mr.  Ellison and legal counsel to cooperate with Humboldt  Bancorp in
producing a definitive agreement embodying the proposed terms for Tehama Bancorp
to consider. Commencing on August 15, 2000, Tehama Bancorp and its financial and
legal advisors commenced a due diligence review of Humboldt Bancorp.

     On  September 6, 2000,  Tehama  Bancorp's  board of directors  met with its
financial and legal advisors and had a detailed discussion of the results of the
due  diligence  review of  Humboldt  Bancorp  and a proposed  definitive  merger
agreement which had been prepared by Humboldt  Bancorp's counsel in consultation
with Tehama Bancorp's executive officers and legal counsel,  based upon the term
sheet presented at the July 24, 2000, meeting.  Representatives of Dain Rauscher
presented an analysis of the proposed merger  consideration in relation to other
bank  merger  transactions  and in  relation  to the  potential  value of Tehama
Bancorp as an  independent  entity and orally  advised the board  that,  in Dain
Rauscher's  opinion,  the merger  consideration  offered by Humboldt Bancorp was
fair from a financial point of view to the  shareholders of Tehama Bancorp.  The
Tehama Bancorp board of directors  authorized execution of the definitive merger
agreement at the conclusion of that meeting.

     Reasons for the Merger.  The Tehama Bancorp board of directors believes the
merger is fair from a financial point of view to its shareholders and is also in
the best interests of its shareholders.  Therefore,  the Tehama Bancorp board of
directors  unanimously  approved the merger and unanimously  recommends that its
shareholders  approve the merger.  In reaching its decision,  the Tehama Bancorp
board of directors considered the following factors:

     o    the business,  operations,  condition and earnings of Humboldt Bancorp
          on a historical and prospective basis and of the combined company on a
          pro forma basis;

     o    the potential cost savings,  operating  efficiencies and opportunities
          for revenue  enhancement  available to the combined company  following
          the merger;

     o    the compatibility of the respective businesses, operating philosophies
          and  strategic  objectives  of Tehama  Bancorp and  Humboldt  Bancorp,
          including their decentralized  management structures and the growth of
          their respective fee-based businesses;

     o    the terms of the merger agreement, including the conversion ratio as a
          function of Tehama Bancorp's earnings and book value per share;

     o    the current  and  prospective  economic  and  competitive  environment
          facing the financial services industry generally and Tehama Bancorp in
          particular,  and the  probable  importance  of  economies  of scale in
          enhancing efficiency and profitability;

     o    Humboldt  Bancorp's  success in completing and  implementing  previous
          acquisitions of financial institutions;

<PAGE>22

     o    the  necessity  for  Tehama   Bancorp  to  increase  its  spending  on
          technology were it to remain independent in the future;

     o    the  presentation  of Dain  Rauscher  to the Tehama  Bancorp  board of
          directors  on  March  16,  2000,  and  its  opinion  that  the  merger
          consideration   is  fair  from  a  financial  point  of  view  to  the
          shareholders of Tehama Bancorp;

     o    the  expectation  that the merger will be tax-free  (except as to cash
          paid in lieu of fractional  interests and for  dissenting  shares) for
          federal  income tax purposes to Tehama Bancorp  shareholders  and will
          qualify  as a  pooling  of  interests  for  accounting  and  financial
          reporting purposes;

     o    the  generally  favorable  impact  that the  Tehama  Bancorp  board of
          directors  expects the merger to have on Tehama  Bancorp's  customers,
          employees  and  the  communities  in its  service  area,  through  the
          expanded financial services and increased lending  capabilities Tehama
          Bancorp will be able to offer; and

     o    the  comparative   benefit  of  other   potential   candidates  for  a
          combination  transaction and the cost and benefits of continuing as an
          independent bank.

     The Tehama Bancorp board of directors did not assign relative weight to any
of the foregoing  factors,  and different  directors may have assigned different
weights to different  factors.  The foregoing  discussion of the information and
factors  considered by the Tehama  Bancorp board of directors is not intended to
be  exhaustive  but is believed to include all material  factors that the Tehama
Bancorp board of directors considered.

     The Tehama Bancorp board of directors  believes that the merger,  including
the conversion  rate, is fair to and in the best interests of Tehama Bancorp and
you as the Tehama Bancorp  shareholders and has unanimously approved and adopted
the merger  agreement  and  recommends  that you vote for approval of the merger
agreement.

Tehama Bancorp Conversion Rate

     The boards of directors of Humboldt  Bancorp and Tehama Bancorp  determined
the conversion rate in an arm's length negotiation.

     Each share of Tehama Bancorp  common stock that is outstanding  immediately
prior to the  merger,  other  than  shares to which its  holders  have  properly
exercised  dissenters'  rights,  will be converted into 1.775 shares of Humboldt
Bancorp common stock.

     You are urged to obtain  current  market  quotations  for Humboldt  Bancorp
common stock and Tehama  Bancorp  common  stock.  It is expected that the market
price of Humboldt  Bancorp common stock will fluctuate  between the date of this
document and the date on which the merger is completed and  thereafter.  Because
the number of shares of Humboldt  Bancorp  common stock to be received by you in
the merger will be determined  based on the average closing price and the market
price of Humboldt  Bancorp common stock is subject to fluctuation,  the value of
the shares of Humboldt  Bancorp common stock that you will receive in the merger
may  increase  or  decrease  before and after the  merger.  This risk is further
explained under "Risk Factors" since the market price of Humboldt Bancorp common
stock will vary, Tehama Bancorp  shareholders cannot be sure of the value of the
Humboldt Bancorp common stock to be received in the merger.

     Fractional  Shares.  No fractional  shares of Humboldt Bancorp common stock
will be issued in the merger.  Instead,  if you would  otherwise  be entitled to
receive a  fractional  share,  Humboldt  Bancorp  will pay you an amount in cash
equal to the product  obtained  by  multiplying  (1) the  closing  sale price of
Humboldt  Bancorp common stock as reported on the Nasdaq  National Market on the
day immediately preceding the merger closing date, by (2) the fraction of the

<PAGE>23

share of Humboldt Bancorp common stock to which you would otherwise be entitled.
You will  not be  entitled  to  dividends  or other  rights  in  respect  of any
fractional share.

Exchange Procedure

     Humboldt  Bancorp has contracted  with Illinois  Stock Transfer  Company to
effect the exchange and issuance of its securities in the merger.  On or as soon
as practicable after the merger, Humboldt Bancorp will deliver to Illinois Stock
Transfer Company (i) certificates of Humboldt Bancorp common stock and (ii) cash
equal to the amount of any fractional shares.

     Upon  surrender to Illinois  Stock  Transfer  Company of one or more Tehama
Bancorp stock  certificates  for  cancellation,  accompanied by the  transmittal
letter  that will be sent to the Tehama  Bancorp  shareholders,  Illinois  Stock
Transfer  Company will promptly  deliver,  to each holder of surrendered  Tehama
Bancorp stock certificates, certificates for shares of Humboldt common stock and
a check for payment of any fractional shares.

     Until  Tehama  Bancorp  stock   certificates   have  been  surrendered  and
exchanged,  each outstanding  Tehama Bancorp stock  certificate will constitute,
for all  corporate  purposes,  the right to receive  shares of Humboldt  Bancorp
common stock.  Until Tehama  Bancorp  certificates  are  surrendered,  dividends
accrued on  Humboldt  Bancorp  stock after the merger will not be payable on the
Humboldt Bancorp shares into which the Tehama Bancorp shares are converted,  and
the holders entitled to Humboldt Bancorp shares will not be entitled to vote.

     If any holder of Tehama  Bancorp common stock is unable to surrender his or
her Tehama Bancorp stock  certificates  because the stock certificates have been
lost or  destroyed,  the holder may instead  deliver an affidavit  and indemnity
undertaking in form and substance and, if required,  with surety satisfactory to
Illinois Stock Transfer Company and Humboldt Bancorp.

     All  outstanding  stock options to acquire Tehama Bancorp common stock will
be assumed by Humboldt  Bancorp  upon  completion  of the merger,  and  Humboldt
Bancorp common stock,  adjusted as to price and number of shares to take account
of the conversion ratio, will be substituted for Tehama Bancorp shares when such
options are exercised.

Interests of Certain Persons in the Merger and Material Contracts

     In considering the  recommendations  of the boards of directors of Humboldt
Bancorp and Tehama  Bancorp for  approval of the  merger,  the  shareholders  of
Humboldt  Bancorp and Tehama Bancorp should be aware that certain members of the
boards of directors of Humboldt  Bancorp and Tehama Bancorp may have substantial
interest in the merger as described below.

     At the effective time of the merger,  there will be 11 members of the board
of directors of Humboldt Bancorp  consisting of seven of the existing 12 members
of the current board of directors of Humboldt  Bancorp and four new members from
the board of directors of Tehama  Bancorp.  At the effective time of the merger,
there  shall  also be 16  members  of the board of  directors  of  Tehama  Bank,
consisting  of the then existing 14 members of the current board of directors of
Tehama  Bank,  and two new  members  from the  board of  directors  of  Humboldt
Bancorp.

     It is presently  anticipated  that current  Tehama  Bancorp  directors John
Koeberer,  Garry Fish, Gary Katz and Gary Napier will be appointed  directors of
Humboldt  Bancorp,  and Messrs.  Mason,  Angell,  Evans,  Francesconi,  Janssen,
Winzler and Weborg shall remain directors of Humboldt  Bancorp.  Further,  it is
expected that Humboldt Bancorp director  Theodore S. Mason and one other current
Humboldt Bancorp board member will be appointed as directors of Tehama Bank.

<PAGE>24

     In  addition,  each  director  of  Humboldt  Bancorp  has  entered  into an
agreement with Tehama  Bancorp,  and each director of Tehama Bancorp has entered
into an  agreement  with  Humboldt  Bancorp,  which  provides  that the director
agrees:

     o    to  recommend  that the  shareholders  of  Humboldt  Bancorp or Tehama
          Bancorp,  as the case may be,  approve  the  agreement,  and to advise
          Humboldt  Bancorp's  or Tehama  Bancorp's  shareholders  to reject any
          subsequent  proposal or offer  received by Humboldt  Bancorp or Tehama
          Bancorp,  as  the  case  may  be,  relating  to  any  purchase,  sale,
          acquisition,  merger, or other form of business combination  involving
          Humboldt  Bancorp  or  Tehama  Bancorp  or any of its  assets,  equity
          securities or debt securities,  and to proceed with the merger between
          Humboldt Bancorp and Tehama Bancorp,  unless the directors of Humboldt
          Bancorp or Tehama  Bancorp,  as the case may be,  has been  advised by
          outside  financial  advisors and legal counsel that he should not take
          that action;

     o    not to take any action  that will alter or affect in any way the right
          to vote the shares of Humboldt Bancorp or Tehama Bancorp common stock,
          except with the prior  written  consent of Humboldt  Bancorp or Tehama
          Bancorp,  as the case may be,  or to change  the right  from that of a
          shared  right of the director to vote the shares  Humboldt  Bancorp or
          Tehama  Bancorp  common  stock to a sole right of the director to vote
          the shares of Humboldt  Bancorp or Tehama  Bancorp common stock as the
          case may be; and

     o    to vote all shares of Humboldt  Bancorp or Tehama Bancorp common stock
          that the director has power to vote in favor of the merger.

     Further, it is the intent of Humboldt Bancorp that Tehama Bank enter into a
contract with Mr.  William  Ellison,  President and Chief  Executive  Officer of
Tehama Bank,  to serve in the same  capacity for Tehama Bank as a subsidiary  of
Humboldt Bancorp following the merger. It is anticipated that most other present
officers  and  employees of Tehama Bank will  initially  continue in the same or
similar capacities with Tehama Bank.

Regulatory Approval and Completion of the Merger

     The merger must be  approved  by the  California  Department  of  Financial
Institutions  and by the Board of Governors of the Federal Reserve  System.  The
approval of the merger by the  California  Department of Financial  Institutions
and the Federal  Reserve Board is not a  recommendation  or  endorsement  of the
merger by any of those agencies.

Closing Date

     The  closing of the  merger  will take place no more than 30 days after the
receipt  of  the  last  required  regulatory  approval  and  expiration  of  all
applicable waiting periods.

     Also, the conditions  precedent to the obligations of Humboldt  Bancorp and
Tehama  Bancorp  must be  satisfied,  or  written  waiver of the  conditions  by
Humboldt Bancorp and Tehama Bancorp, as the case may be, must be received.

     It  is  presently   anticipated  that  the  merger  will  be  completed  by
___________, 2000.

Conditions to the Merger

     The merger agreement  provides that various  conditions must be met for the
completion of the merger.  These conditions include, but are not limited to, the
following:

<PAGE>

     o    Approval of the merger  agreement and  authorization  of the merger by
          the vote of the  holders of a majority  of the  outstanding  shares of

     o    Approval and issuance of any permits  required and  expiration  of all
          waiting periods;

     o    No action taken, or any law, regulation or order enacted,  enforced or
          deemed applicable to the merger, by any government entity which:

          o    makes the completion of the merger illegal;

          o    requires  the  divestiture  by Humboldt  Bancorp of any  material
               asset  or of a  material  portion  of the  business  of  Humboldt
               Bancorp; or

          o    imposes any condition upon Humboldt Bancorp that, in the judgment
               of Humboldt Bancorp, would be materially burdensome;

     o    Humboldt Bancorp and Tehama Bancorp receive a letter from Richardson &
          Co. that the merger may be accounted for as a pooling-of-interests;

     o    The  representations  and  warranties  of Humboldt  Bancorp and Tehama
          Bancorp set forth in the merger agreement must be true in all material
          respects as of the date of completion of the merger;  Humboldt Bancorp
          and Tehama  Bancorp must  perform and comply in all material  respects
          with the merger agreement; and no event or condition entitling a party
          to  terminate  the  merger  agreement  shall have  occurred  without a
          waiving of the condition by the party entitled to waive the condition;

     o    An opinion  shall have been  received  from Bartel Eng Linn & Schroder
          that the merger will be a tax-free  exchange  for  federal  income tax
          purposes;

     o    No change shall have occurred in the consolidated financial condition,
          consolidated   net  assets,   shareholders'   equity,   business,   or
          consolidated  operating  results of Humboldt Bancorp from December 31,
          1999,  to the date of  completion  of the  merger  that  results  in a
          material  adverse effect as to Humboldt  Bancorp and its  subsidiaries
          taken as a whole;

     o    Neither Tehama  Bancorp's  fairness  opinion from Dain  Rauscher,  nor
          Humboldt  Bancorp's  fairness  opinion  from  D. A.  Davidson,  may be
          revoked prior to the special meetings of shareholders.

Waiver, Amendment, and Termination

     Any term or  provision  of the  merger  agreement,  other  than  regulatory
approval or any of the provisions  required by law, may be waived in writing, at
any time,  by the party  which is, or whose  shareholders  are,  entitled to the
benefits of the term or provision.

     The  merger  agreement  provides  that it may be  terminated  prior  to the
completion  of the merger.  These  events  include,  but are not limited to, the
following:

     o    By mutual  consent of the boards of directors of Humboldt  Bancorp and
          Tehama Bancorp;

     o    By either  party if the  merger is not  accounted  for as a pooling of
          interests;

<PAGE>26

     o    By either  party if holders  owning  more than 10% of the  outstanding
          shares of Tehama  Bancorp  common  stock and Humboldt  Bancorp  common
          stock have exercised their dissenter's rights;

     o    By Humboldt  Bancorp or Tehama Bancorp upon the failure to satisfy any
          conditions  specified  in the merger  agreement  if the failure is not
          caused by any action or inaction of the party requesting termination;

     o    By Humboldt  Bancorp or Tehama  Bancorp if an  Acquisition  Event,  as
          defined in the merger agreement, occurs involving the other party;

     o    By Humboldt Bancorp or Tehama Bancorp if there is a material breach of
          any of the  representations  or warranties of the other, which breach,
          in the reasonable  opinion of the terminating  party,  cannot be cured
          prior to the merger and, in the reasonable  opinion of the terminating
          party,  is likely to have a material  adverse  effect on the breaching
          party or upon the completion of the merger; or

     o    By Humboldt Bancorp or Tehama Bancorp if the average trading price, as
          defined  in the  merger  agreement,  is below  $9.75 per share and the
          parties do not renegotiate the conversion rate.

Liquidated Damages

     If an  Acquisition  Event,  as  defined  in the  merger  agreement,  occurs
involving Tehama Bancorp,  then Tehama Bancorp shall pay to Humboldt Bancorp the
sum of $1,500,000  in cash and Humboldt  Bancorp shall have an option to acquire
up to 19.9% of the outstanding  shares of Tehama Bancorp at $16.50 per share. If
an acquisition event occurs involving  Humboldt  Bancorp,  then Humboldt Bancorp
shall pay to Tehama  Bancorp the sum of $1,500,000 in cash,  and Tehama  Bancorp
shall  have the  option  to  acquire  up to 19.9% of the  outstanding  shares of
Humboldt Bancorp at $11.75 per share.

     If the merger  agreement is terminated by Tehama Bancorp as a result of the
revocation  of the Tehama  Bancorp  fairness  opinion;  or if the  agreement  is
terminated  by  Humboldt  Bancorp  because  of  a  breach  of  Tehama  Bancorp's
representations or warranties, a default by Tehama Bancorp, or disclosure in the
updated  schedules to the merger  agreement of a material  adverse event,  where
such breach,  default or material  adverse event is within the control of Tehama
Bancorp or its directors or executive officers, then Tehama Bancorp shall pay to
Humboldt  Bancorp the sum of $500,000 in cash. If Tehama  Bancorp enters into an
acquisition agreement within 180 days following termination by Humboldt Bancorp,
Tehama Bancorp shall pay to Humboldt Bancorp an additional $250,000.

     If the merger  agreement is terminated  by Humboldt  Bancorp as a result of
the revocation of the Humboldt Bancorp fairness opinion;  or if the agreement is
terminated  by  Tehama  Bancorp  because  of  a  breach  of  Humboldt  Bancorp's
representations or warranties,  a default by Humboldt Bancorp,  or disclosure in
the updated schedules to the merger agreement of a material adverse event, where
such breach, default or material adverse event is within the control of Humboldt
Bancorp or its directors or executive officers,  then Humboldt Bancorp shall pay
to Tehama  Bancorp the sum of $500,000 in cash. If Humboldt  Bancorp enters into
an  acquisition  agreement  within  180 days  following  termination  by  Tehama
Bancorp, Humboldt Bancorp shall pay to Tehama Bancorp an additional $250,000.

                   OPINION OF TEHAMA BANCORP FINANCIAL ADVISOR

     Tehama  Bancorp  retained Dain Rauscher to act as its financial  advisor in
connection  with the merger and related  matters based upon its  qualifications,
expertise and reputation.  On September 6, 2000, Dain Rauscher rendered its oral
opinion to the board of directors of Tehama Bancorp that the consideration to be
received pursuant to the merger agreement is fair from a financial point of view
to the holders of Tehama Bancorp common stock.

THE FULL TEXT OF THE WRITTEN OPINION  DELIVERED AS OF THE DATE OF THIS DOCUMENT,
SETS FORTH, AMONG OTHER THINGS,  ASSUMPTIONS MADE, PROCEDURES FOLLOWED,  MATTERS
CONSIDERED,  AND LIMITATIONS ON THE REVIEW UNDERTAKEN, IS ATTACHED AS APPENDIX B
TO THIS DOCUMENT.  TEHAMA  BANCORP'S  SHAREHOLDERS ARE URGED TO READ THE OPINION
CAREFULLY AND IN ITS ENTIRETY.  THE OPINION DOES NOT CONSTITUTE A RECOMMENDATION
TO ANY SHAREHOLDER OF TEHAMA BANCORP AS TO HOW SUCH  SHAREHOLDER  SHOULD VOTE AT
THE SPECIAL MEETING.

     Tehama Bancorp engaged Dain Rauscher in March 2000, to act as its exclusive
financial advisor in connection with the merger.  Dain Rauscher agreed to assist
Tehama  Bancorp  in  analyzing,   structuring,   negotiating   and  effecting  a
transaction with Humboldt Bancorp. Tehama Bancorp selected Dain Rauscher because
Dain  Rauscher  is  a  nationally   recognized   investment-banking   firm  with
substantial  experience  in  transactions  similar to the merger and is familiar
with  Tehama  Bancorp  and  its  business.  As part  of its  investment  banking
business,  Dain Rauscher is  continually  engaged in the valuation of businesses
and their securities in connection with mergers and acquisitions.

     A  representative  of Dain  Rauscher  attended  the  meeting  of the Tehama
Bancorp  board of  directors  held on  September  6,  2000,  at which the Tehama
Bancorp board of directors considered and approved the merger agreement.  At the
September 6 meeting,  Dain  Rauscher  rendered an oral opinion  that, as of that
date, the conversion rate was fair to Tehama Bancorp and its shareholders from a
financial  point of view. That opinion was reconfirmed in writing as of the date
of this document.

     Dain  Rauscher's  opinion  is  directed  to the  Tehama  Bancorp  board  of
directors and  addresses  only the  conversion  rate of 1.775 shares of Humboldt
Bancorp common stock for each share of Tehama Bancorp common stock.  It does not
address the underlying business decision to proceed with the merger and does not
constitute a recommendation to any shareholder as to how the shareholder  should
vote at the Meeting with respect to the merger or any matter related thereto.

     In rendering its opinion, Dain Rauscher reviewed, among other things,

     o    the merger agreement,

     o    annual  reports to  shareholders  and  annual  reports on Form 10-K of
          Humboldt Bancorp,

     o    annual  reports to  shareholders  and  annual  reports on Form 10-K of
          Tehama Bancorp,

     o    quarterly reports on Form 10-Q of Humboldt Bancorp,

     o    quarterly reports on Form 10-Q of Tehama Bancorp, and

     o    certain internal  financial  analyses and forecasts for Tehama Bancorp
          and Humboldt Bancorp prepared by their respective managements.

     Dain Rauscher also held  discussions  with members of senior  management of
Tehama Bancorp and Humboldt Bancorp regarding their respective:

     o    past and current business operations,

     o    regulatory relationships,

     o    financial condition, and

<PAGE>28

     o    future prospects of the respective companies.

     Dain Rauscher compared certain  financial and stock market  information for
Humboldt  Bancorp and Tehama Bancorp with similar  information for certain other
companies  with publicly  traded  securities,  reviewed the  financial  terms of
certain recent  business  combinations  in the banking  industry,  and performed
other studies and analyses that it considered appropriate.

     In conducting its review and arriving at its opinion,  Dain Rauscher relied
upon and assumed the accuracy and completeness of all of the financial and other
information provided to it or publicly available.  Dain Rauscher did not attempt
to  verify  such  information  independently.  Dain  Rauscher  relied  upon  the
managements of Humboldt Bancorp and Tehama Bancorp as to the  reasonableness and
achievability  of the  financial and operating  forecasts and  projections  (and
assumptions and bases therefor) provided to Dain Rauscher. Dain Rauscher assumed
that those forecasts and projections  reflected the best available estimates and
judgments of the respective  managements of Humboldt Bancorp and Tehama Bancorp.
Dain Rauscher also assumed, without independent verification, that the aggregate
allowances for loan losses for Humboldt  Bancorp and Tehama Bancorp are adequate
to cover those losses.  Dain Rauscher did not make or obtain any  evaluations or
appraisals  of the  property of  Humboldt  Bancorp or Tehama  Bancorp,  and Dain
Rauscher did not examine any individual credit files.

     The projections furnished to Dain Rauscher and used by it in certain of its
analyses were prepared by the senior  managements of Tehama Bancorp and Humboldt
Bancorp. Neither Tehama Bancorp nor Humboldt Bancorp publicly discloses internal
management  projections of the type provided to Dain Rauscher in connection with
its review of the merger. As a result, such projections were not prepared with a
view toward public disclosure.  The projections were based on numerous variables
and  assumptions  that are inherently  uncertain,  including  factors related to
general economic and competitive conditions.  ACCORDINGLY,  ACTUAL RESULTS COULD
VARY SIGNIFICANTLY FROM THOSE SET FORTH IN THE PROJECTIONS.

     The  following  is a summary of the  material  analyses  performed  by Dain
Rauscher  related to the oral  opinion  rendered  to Tehama  Bancorp's  board of
directors on September 6, 2000.

     Transaction Summary

     Dain Rauscher  calculated the merger  consideration  to be paid pursuant to
the  exchange  ratio as a multiple  of Tehama  Bancorp's  book value at June 30,
2000,  earnings for the twelve  months ended June 30, 2000,  and 2000  estimated
earnings. This computation was based on Tehama Bancorp's June 30, 2000, tangible
book value of $10.39 per share,  Tehama Bancorp's earnings for the twelve months
ended June 30, 2000, of $1.42 per share, and Tehama Bancorp's estimated earnings
in 2000 of $1.60 per share.  The  computation  was also based upon a  conversion
rate of 1.775  Humboldt  Bancorp  shares for each Tehama  Bancorp  share and the
closing  price of Humboldt  Bancorp's  common  stock on September  19, 2000,  of
$11.50. Based on those assumptions,  this analysis indicated that Tehama Bancorp
shareholders  would receive shares of Humboldt Bancorp common stock worth $20.41
for each share of Tehama  Bancorp  common  stock held and that this amount would
represent a multiple of 1.96 times  tangible  book value per share,  14.37 times
earnings for the twelve  months ended June 30, 2000,  and 12.76 times  estimated
2000 earnings per share.

     Discounted Cash Flow Analysis

     Dain  Rauscher  estimated the present value of future cash flows that would
accrue to a holder of a share of Tehama  Bancorp  Common Stock assuming that the
shareholder  held the stock for five  years and then sold it. The  analysis  was
based on earnings forecasts prepared by management on a stand-alone, independent
basis for the year 2000 and annual net  income  growth  rates from 8.0% to 12.0%
for the years 2001 through  2004.  A 30%  dividend  payout ratio was assumed for
Tehama  Bancorp  through the year 2004.  An  estimated  year 2004 year end stock
price was estimated by  multiplying  the projected  annual  earnings by earnings
multiples  ranging from 10 to 20 times.  The estimated stock price for each year
and the estimated dividends were discounted at rates from 14% to 18%. These

<PAGE>29

rates were selected because, in Dain Rauscher's  experience,  they represent the
risk-adjusted  rates of return that  investors in securities  such as the common
stock of Tehama Bancorp would require.  On the basis of these assumptions,  Dain
Rauscher  calculated  a range of present  values  ranging from $15.09 to $30.85.
These values were compared to the $20.41 offer from Humboldt Bancorp.

     The discounted  cash flow present value analysis is a widely used valuation
methodology  that relies on numerous  assumptions,  including asset and earnings
growth rates,  terminal values and discount rates.  The analysis did not purport
to be  indicative  of the actual  values or  expected  values of Tehama  Bancorp
Common Stock.

     Selected Transaction Analysis

     Using publicly available information,  Dain Rauscher reviewed certain terms
and financial characteristics, including historical price-to-earnings ratio, the
price-to-tangible  book  ratio,  and the  tangible  book  value  premium to core
deposits paid in prior  commercial  banking  institution  merger or  acquisition
transactions.  The first  comparable  group  ("Comparable  Group One")  included
nationwide  transactions  announced  since  January 1, 1999,  with  sellers with
assets  between $100 million and $300 million that earned  greater than 0.75% on
total  assets.  Comparable  Group One  included  89  transactions.  The  average
price-to-last  available  twelve  month  earnings for  Comparable  Group One was
19.77x,  and ranged  from 9.16x to 42.32x.  The average  price-to-tangible  book
value for Comparable Group One was 2.58x, and ranged from 1.20x to 4.76x.

Comparable Group One                             Average           Range
                                                 -------           -----
  Price-to-last available 12 month earnings       19.77x      9.16x to 42.32x
  Price-to-tangible book value                     2.58x       1.20x to 4.76x


     The second comparable group ("Comparable Group Two") included  transactions
announced  since January 1, 1999, with sellers located in California with assets
between $100  million and $300  million that earned  greater than 0.75% on total
assets. Comparable Group Two included 22 transactions. The average price-to-last
twelve  month  earnings  for  Comparable  Group Two was 18.90x,  and ranged from
11.61x to 27.08x. The average  price-to-tangible book value for Comparable Group
Two was 2.51x, and ranged from 1.32x to 4.41x.

Comparable Group Two                             Average           Range
                                                 -------           -----
  Price-to-interest last 12 month earnings        18.90x     11.61x to 27.08x
  Price-to-tangible book value                     2.51x       1.32x to 4.41x

     No company or  transaction  used as a comparison  in the above  analysis is
identical to Humboldt  Bancorp,  Tehama Bancorp or the merger.  Accordingly,  an
analysis of these  results is not  mathematical.  Rather,  it  involves  complex
considerations and judgments  concerning  differences in financial and operating
characteristics  of the companies and other factors that could affect the public
trading value of the companies to which they are being compared.

     Selected Peer Group Analysis

     Dain Rauscher compared the financial  performance and market performance of
Humboldt  Bancorp with selected  banking  institutions  with assets between $500
million and $1 billion earning over 1.00% return on assets (the "Comparable Bank
Group") deemed relevant by Dain Rauscher.

     The comparisons were based on:

     o    various financial measures,

<PAGE>30

     o    earnings performance,

     o    operating efficiency,

     o    capital adequacy,

     o    asset quality, and

     o    various measures of market performance including

          o    market/book values,

          o    price to earnings, and

          o    dividend yields.

     To perform this analysis,  Dain Rauscher used the financial  information as
of and for the latest available twelve months (LTM) and market price information
as of September 6, 2000.

     Dain Rauscher's analysis showed the following concerning Humboldt Bancorp's
financial performance:

</TABLE>

     For purposes of the above  calculations,  all earnings  estimates are based
upon the estimates for Humboldt Bancorp provided by Humboldt Bancorp management.
Because of the inherent  differences in the  businesses,  operations,  financial
conditions and prospects of Humboldt  Bancorp and the companies  included in the
Comparable Bank Group, Dain Rauscher believed that a purely quantitative

<PAGE>31

comparable company analysis would not be particularly  meaningful in the context
of the merger.  Dain Rauscher  believed that the appropriate use of a comparable
company analysis in this instance would involve qualitative judgments concerning
the  differences  between  Humboldt  Bancorp and the  companies  included in the
Comparable  Bank Group which would affect the trading  values of the  comparable
companies.

     Contribution Analysis

     Dain  Rauscher  analyzed  the  relative  contribution  of each of  Humboldt
Bancorp  and  Tehama  Bancorp  to  certain  pro forma  balance  sheet and income
statement items of the combined entity. The contribution analysis showed:

Tehama Bancorp contribution to:
   Combined common equity...........................................31.30%
   Combined 2000 estimated net income without cost savings..........31.27%
   Combined total assets............................................28.90%
   Tehama Bancorp estimated pro forma ownership.....................37.50%

     Dain Rauscher  compared the relative  contribution of the balance sheet and
income statement items with the estimated pro forma ownership for Tehama Bancorp
shareholders based on a conversion rate of 1.775.

     Other Analyses

     Dain Rauscher  compared the relative  financial and market  performance  of
Tehama  Bancorp  and  Humboldt  Bancorp to a variety of relevant  industry  peer
groups and indices.  Dain  Rauscher also reviewed  earnings  estimates,  balance
sheet  composition,  historical  stock  performance and other financial data for
Humboldt Bancorp.

     In connection with its opinion dated as of the date of this document,  Dain
Rauscher performed  procedures to update, as necessary,  certain of the analyses
described  above.  Dain Rauscher  reviewed the assumptions on which the analyses
described above were based and the factors  considered in connection  therewith.
Dain Rauscher did not perform any analyses in addition to those  described above
in updating its September 6, 2000, oral opinion.

     The  summary  set  forth  above  is  not  a  complete  description  of  the
presentation  by Dain Rauscher to Tehama  Bancorp's board of directors or of the
analysis  performed by Dain Rauscher.  The preparation of a fairness  opinion is
not necessarily  susceptible to partial  analysis or summary  description.  Dain
Rauscher  believes  that its  analyses  and the  summary set forth above must be
considered  as a whole.  In  addition,  Dain  Rauscher  may have  given  various
analyses more or less weight than other  analyses,  and may have deemed  various
assumptions more or less probable than other assumptions,  so that the ranges of
valuations  resulting from any particular analysis described above should not be
taken to be Dain  Rauscher's  view of the actual value of Tehama  Bancorp or the
combined companies.  The fact that any specific analysis has been referred to in
the summary  above is not meant to indicate that such analysis was given greater
weight than any other analysis.

     In performing its analyses,  Dain Rauscher made numerous  assumptions  with
respect to industry  performance,  general business and economic  conditions and
other  matters,  many of which are beyond  the  control  of Tehama  Bancorp  and
Humboldt  Bancorp.  The analyses  performed by Dain Rauscher are not necessarily
indicative of actual values or actual future results, which may be significantly
more or less  favorable  than  suggested by such  analyses.  Such  analyses were
prepared  solely as part of Dain  Rauscher's  analysis  of the  fairness  of the
consideration  to be received  by you in the merger and were  provided to Tehama
Bancorp's  board of directors in connection with the delivery of Dain Rauscher's
opinion. The analyses do not purport to be appraisals or to reflect the prices

<PAGE>32

at which a company might  actually be sold or the prices at which any securities
may trade at the present time or at any time in the future.  The forecasts  used
by Dain  Rauscher in certain of its analyses are based upon  numerous  variables
and assumptions,  which are inherently  unpredictable and must be considered not
certain of  occurrence  as  projected.  Accordingly,  actual  results could vary
significantly from those contemplated in such forecasts.

     As described under "Description of the  Merger--Background  and Reasons for
the Merger," Dain Rauscher's  opinion and presentation to the board of directors
were among the many factors taken into  consideration  by Tehama Bancorp's board
of directors in making its determination to approve the merger agreement.

     Dain Rauscher Wessels

     The Tehama  Bancorp  board of directors  has retained  Dain  Rauscher as an
independent  contractor to act as financial  adviser to Tehama Bancorp regarding
the merger.  In the  ordinary  course of its business as a  broker-dealer,  Dain
Rauscher may, from time to time,  purchase  securities from, and sell securities
to, Tehama Bancorp and Humboldt  Bancorp.  As a market maker in securities  Dain
Rauscher  may from time to time  have a long or short  position  in,  and buy or
sell, debt or equity  securities of Tehama Bancorp and Humboldt Bancorp for Dain
Rauscher's own account and for the accounts of its customers.  Dain Rauscher has
not  previously  provided  investment  banking  services to Tehama Bancorp or to
Humboldt Bancorp.

     Tehama Bancorp and Dain Rauscher have entered into an agreement relating to
the  services  to be provided by Dain  Rauscher in  connection  with the merger.
Tehama  Bancorp has agreed to pay Dain  Rauscher  $75,000 on the date the merger
was publicly announced and, at the time of closing, a cash fee equal to 1.50% of
the  market  value  of the  aggregate  consideration  paid in  exchange  for the
outstanding shares of common stock of Tehama Bancorp in the merger.  Pursuant to
the Dain Rauscher engagement agreement,  Tehama Bancorp also agreed to reimburse
Dain Rauscher for reasonable  out-of-pocket  expenses and disbursements incurred
in connection with its retention and to indemnify Dain Rauscher  against certain
liabilities, including liabilities under the federal securities laws.

                  OPINION OF HUMBOLDT BANCORP FINANCIAL ADVISOR

     Humboldt  Bancorp's  board  retained  D.A.  Davidson in April  2000,  on an
exclusive basis, to provide limited  financial  advisory services and a fairness
opinion in connection with the proposed merger.  D.A.  Davidson,  as part of its
investment  banking  business,  is engaged in the valuation of banking and other
businesses  and their  securities in connection  with mergers and  acquisitions,
negotiated  underwritings,  competitive  biddings,  secondary  distributions  of
listed and unlisted  securities,  private  placements and valuations for estate,
corporate and other purposes.  Humboldt  Bancorp's  board of directors  retained
D.A.  Davidson based upon its  experience as a financial  advisor in mergers and
acquisitions   of  financial   institutions   and  its  knowledge  of  financial
institutions.  Humboldt Bancorp has retained D.A. Davidson in the past for other
investment  banking  assignments.  D.A.  Davidson  makes a  market  in  Humboldt
Bancorp's common stock on the Nasdaq National Market.

     On August 17, 2000, a representative of D.A. Davidson attended the Humboldt
Bancorp  board of  directors'  meeting  at  which  Humboldt  Bancorp's  board of
directors  considered  and approved  the merger  agreement.  The  representative
presented  orally to the board of directors the D.A.  Davidson  fairness opinion
that,  as of the  date  of the  meeting,  the  merger  consideration  to be paid
pursuant to the merger  agreement is fair from a financial  point of view to the
holders of Humboldt  Bancorp  common  stock.  That  opinion was  reconfirmed  in
writing  as of the  date of this  document.  The  full  text of D.A.  Davidson's
opinion,  including  review  procedures,  valuation  methods and assumptions and
results of its analyses, is attached as Appendix C to this document.

     D.A.  Davidson's  opinion is directed to the  Humboldt  Bancorp's  board of
directors and addresses only the merger consideration of exchanging 1.775 shares
of Humboldt  Bancorp common stock for each share of Tehama Bancorp common stock.
It does not address the underlying business decision to proceed with the merger

<PAGE>33

and  does not  constitute  a  recommendation  to any  shareholder  as to how the
shareholder  should vote at the meeting  with respect to the merger or any other
matter related thereto.

Review Procedures

     In connection with providing this opinion, D.A. Davidson,

     o    reviewed the merger agreement;

     o    reviewed  certain   publicly   available   financial   statements  and
          regulatory information concerning Humboldt Bancorp and Tehama Bancorp;

     o    reviewed certain internal financial statements and other financial and
          operating  data of  Humboldt  Bancorp and Tehama  Bancorp  provided by
          managements of Humboldt Bancorp and Tehama Bancorp;

     o    discussed the past and current operations,  financial  condition,  and
          future  prospects  of Humboldt  Bancorp and Tehama  Bancorp with their
          executive managements;

     o    compared the relative contributions of assets, liabilities, income and
          expenses to the combined  corporation  by Humboldt  Bancorp and Tehama
          Bancorp;

     o    compared  similar  transactions to the merger of Humboldt  Bancorp and
          Tehama Bancorp;

     o    analyzed the pro forma  results that the  combined  corporation  could
          produce  through  the end of 2002 based  upon  forecasts  prepared  by
          managements of Humboldt Bancorp and Tehama Bancorp; and,

     o    performed  other  analyses  and  reviews,   as  D.A.  Davidson  deemed
          appropriate.

     In connection  with its review,  D.A.  Davidson relied upon and assumed the
accuracy  and  completeness  of all  of the  information  provided  to it.  D.A.
Davidson does not assume any responsibility for independent  verification of the
information.  D.A.  Davidson  assumed that the internal  confidential  financial
projections  prepared by both managements were reasonably  prepared,  reflecting
the best  currently  available  estimates and judgments of the future  financial
performance  of the combined  operation,  and did not  independently  verify the
validity of their assumptions.

     D.A.  Davidson did not make any independent  evaluation or appraisal of the
assets  and  liabilities  of  Humboldt  Bancorp  or Tehama  Bancorp,  nor was it
furnished with any  appraisals.  D.A.  Davidson did not examine  individual loan
files of Humboldt Bancorp or Tehama Bancorp.  D.A.  Davidson is not an expert in
the  evaluation of loan  portfolios for the purpose of assessing the adequacy of
the  allowance  for loan losses and assumed  that these  allowances  are, in the
aggregate, adequate to cover the losses.

     D.A.  Davidson's  opinion is predicated on the merger receiving the tax and
accounting treatment contemplated in the merger agreement.

     D.A.  Davidson provides its opinion without regard to the necessity for, or
level of, any restrictions,  obligations,  undertakings or other actions,  which
may be imposed or required in the course of  obtaining  regulatory  approval for
the merger.

     D.A.  Davidson's  opinion is necessarily  based upon  economic,  market and
other  conditions  in  effect  on and the  information  made  available  to D.A.
Davidson as of August 17, 2000.

     No  limitations  were imposed on D.A.  Davidson  regarding the scope of its
investigation or otherwise by Humboldt Bancorp or Tehama Bancorp.

Valuation Methods

     In connection with providing its opinion, D.A. Davidson performed a variety
of financial analyses, including those summarized in the following sections. The
information  provided  in these  sections is not a complete  description  of the
analyses  that D.A.  Davidson  used in reaching  its opinion.  Preparation  of a
fairness opinion involves  various  determinations  and judgments as to the most
appropriate  and relevant  methods of financial  analysis and the application of
these methods to the particular circumstances.

     A fairness  opinion is not  readily  susceptible  to a partial  analysis or
summary description.  While D.A. Davidson provided the Humboldt Bancorp board of
directors  with  results of the various  analyses  that  follow,  D.A.  Davidson
believes  that  all of its  analysis  must be  considered  as a whole  and  that
selecting  portions  of its  analysis  and  factors  considered  by it,  without
considering all analyses and factors,  or attempting to ascribe relative weights
to some or all such analyses and factors,  or including other discrete  analyses
or factors, could create an incomplete view of the evaluation process underlying
its opinion.

     In performing its analyses,  D.A.  Davidson made numerous  assumptions with
respect to industry  performance,  general business and economic  conditions and
other matters, many of which are beyond the control of Humboldt Bancorp,  Tehama
Bancorp, the combined company and D.A. Davidson.

     The  following  lists  the  summary  analyses  presented  in the  following
sections by D.A. Davidson to Humboldt Bancorp's board of directors on August 17,
2000:

     o    comparable company analysis and historical stock data analysis

     o    analysis of  relative  contributions  of  Humboldt  Bancorp and Tehama
          Bancorp

     o    comparable exchange ratio analysis and transaction analysis

     o    discounted cash flow analysis

     o    pro forma merger analysis and accretion/dilution analysis

Comparable Company Analysis

     D.A. Davidson compared the financial  performance and market performance of
Humboldt  Bancorp  and Tehama  Bancorp  based on various  financial  measures of
earnings performance,  operating efficiency,  capital adequacy and asset quality
and various measures of market performance,  including but not limited to, price
to book values, price to earnings,  and dividend yields to selected bank holding
companies.

     For the purpose of such analysis,  the financial  information  used by D.A.
Davidson  is as of and for the six months  ended  June 30,  2000.  Market  price
information is as of August 16, 2000.  D.A.  Davidson  selected  publicly traded
banking  companies in the northern  California and southern  Oregon markets with
assets between $200 million and $1 billion. D.A. Davidson excluded any bank that
is in the process of being acquired.

     D.A. Davidson's analysis showed the following concerning Humboldt's Bancorp
financial performance:

Historical Stock Data Analysis

     D.A.  Davidson reviewed weekly stock price data for Humboldt Bancorp common
stock and Tehama  Bancorp common stock compared to the Nasdaq Bank Index and S&P
Banking  Index for the period from January 1999  through  August 16, 2000.  This
analysis showed that on a relative  performance  basis,  Humboldt  Bancorp's and
Tehama Bancorp's stock prices went up 27% and 23%, respectively, compared with a
reduction  of 11% for the Nasdaq Bank Index and 12% for the S&P  Banking  Index.
During this same time frame, the Dow Jones Industrial  Average and S&P 500 Index
were both up 20%.

Analysis of Relative Contributions of Parties

     In  preparing  its  opinion,  D.A.  Davidson  also  reviewed  the  relative
financial  contributions  of Humboldt  Bancorp and Tehama Bancorp to certain pro
forma  balance sheet and income  statement  items of the combined  company.  The
chart below shows these percentage contributions.

     Relative Contributions as of and for the Six Months Ended June 30, 2000

                                       Humboldt Bancorp        Tehama Bancorp

     Applying the exchange  ratio to Tehama  Bancorp's  common stock  results in
Humboldt Bancorp shareholders owning approximately 64% of the combined company.

Exchange Ratio Analysis

     D.A.  Davidson  calculated  the  multiple  which the  merger  consideration
represents  based on the exchange ratio in the merger  agreement of 1.775 shares
of Humboldt  Bancorp  common stock for each share of Tehama Bancorp common stock
and the closing  price of Humboldt  Bancorp  common stock as of August 16, 2000.
Based on the $11.625  closing price of Humboldt  Bancorp on August 16, 2000, the
merger consideration  represented a per share value of $20.63 per share for each
share of Tehama Bancorp. The multiples were calculated based on Tehama Bancorp's
June 30, 2000, book value per share of $10.67 and its last twelve month earnings
per  share  of  $1.42.  The  transaction  price to book  value  was 193% and the
transaction price to last twelve month earnings per share was 14.5 times.

Comparison to Selected Transactions

     After  completing  its analysis of the exchange ratio based on the relative
contributions of the parties, D.A. Davidson reviewed comparable  transactions to
validate its analysis.  D.A. Davidson  performed an analysis of selected mergers
of banking organizations in California and Oregon, the western United States and
nationwide  that  have  been  announced  year-to-date  as of  August  16,  2000.
Generally,  the comparable  transactions reinforced D.A. Davidson's opinion that
the exchange ratio was fair. The information that we reviewed included,  but was
not limited to, the following:

        Size of acquired company
        Total transaction value, in aggregate and on a per share basis
        Resulting price-to-book ratios and price-to-earnings multiples

     D.A.  Davidson's  initial selection of a guideline group yielded 14 mergers
of banks in  California  and Oregon  announced  in 2000 as of August  16,  2000.
Within that group of 14, D.A.  Davidson  excluded two transactions  because of a
lack of financial information or the transaction being a merger of equals.

     These  remaining  12  transactions,  which  were  used in  D.A.  Davidson's
analysis, are summarized in the data presented below.

<PAGE>37

        D.A.  Davidson  also  looked at bank  merger  multiples  for the  second
quarter  of 2000 on both a  national  level  and in the  western  United  States
consisting of Alaska,  Arizona,  California,  Hawaii,  Idaho,  Montana,  Nevada,
Oregon, Washington and Wyoming.

Discounted Cash Flow Analysis

     Using a discounted cash flow analysis,  D.A. Davidson  estimated the future
stream of cash flows that Tehama Bancorp could produce over the next five years,
under various  circumstances,  assuming  Tehama Bancorp  performed in accordance
with the earnings forecasts of Tehama Bancorp's  management.  D.A. Davidson then
estimated the terminal  values for Tehama Bancorp common stock at the end of the
period by  applying  multiples  ranging  from 8.0 times to 11.0  times  earnings
projected  in year five.  The cash flow  streams and  terminal  values were then
discounted to present values using different  discount rates (ranging from 13.0%
to 15.0%) chosen to reflect different  assumptions  regarding the required rates
of return to holders or prospective  buyers of Tehama Bancorp common stock.  The
discounted cash flow analysis  indicated  reference ranges of between $19.22 and
$28.41 per share for Tehama Bancorp's common stock.  These values compare to the
merger  consideration  of  $20.63  based on a  conversion  ratio of 1.775  and a
Humboldt Bancorp closing price of $11.625 as of August 16, 2000.

Pro Forma Merger Analysis

     D.A. Davidson reviewed  projections prepared by Humboldt Bancorp management
for year-end 2000 and 2001. D.A. Davidson performed an arithmetic  adjustment to
year-end  2001 results to forecast 2002 results.  This  adjustment  consisted of
applying the same percentage  increase or decrease  between 2000 and 2001 to the
change between 2001 and 2002.

     While D.A. Davidson did not heavily weigh the following information for the
purpose of reaching  its  opinion,  or in analyzing  the  exchange  ratio,  this
information  was  provided to the board of  directors  to  illustrate a possible
outcome for the proposed combined corporation.

     These projections  assume that there will be no substantial shift in future
economic,  financial market, competitive and regulatory conditions, all of which
are difficult or  impossible  to predict and largely  beyond the control of both
parties to the merger.

     Actual results  achieved by the combined  company  following the merger may
vary from this and other forecasts, and the variations may be material. Like all
forward-looking  statements,  this analysis produces results that are inherently
uncertain.

Accretion/Dilution Analysis

     Another  analytic  method that D.A.  Davidson  considered  in reaching  its
opinion is derived  directly from the forecast of combined  company  performance
following the merger  completion.  This review examines  whether and by how much
the  proposed  transaction  is expected  to be  accretive  to  Humboldt  Bancorp
stockholders  in fiscal  year  2001,  the first year of the  combined  company's
operations.  The critical part of this analysis is the set of assumptions  which
drive the earnings per share estimate.

<PAGE>39

     D.A. Davidson concluded that Humboldt Bancorp  management's  assertion that
the proposed  merger will be neutral to slightly  accretive to Humboldt  Bancorp
shareholders  in 2001 is reasonable.  D.A.  Davidson noted that the analysis did
not take into  consideration  any possible  revenue growth coming from the wider
variety of commercial  products  being  offered to  customers.  It also does not
anticipate any buyback of stock.

     D.A.  Davidson's  opinion is directed only to the Humboldt Bancorp board of
directors  and the  question  of  whether  the  exchange  ratio  is fair  from a
financial  perspective and does not constitute a recommendation  to any Humboldt
Bancorp stockholder to vote in favor of the merger.

     D.A.  Davidson acts as a market maker in Humboldt  Bancorp common stock. In
the  ordinary  course  of  D.A.  Davidson's  business,  D.A.  Davidson  and  its
affiliates may actively trade  securities of Humboldt Bancorp and Tehama Bancorp
for their own and for the accounts of customers, and may, therefore, at any time
hold a long or short position in such securities.

     Humboldt  Bancorp  retained D.A.  Davidson to deliver a fairness opinion in
connection with the merger. Humboldt Bancorp agreed to pay D.A. Davidson a total
fee of $85,000,  plus expenses.  Humboldt  Bancorp also agreed to indemnify D.A.
Davidson  and  its  officers  and  employees  against  certain   liabilities  in
connection with its services under the engagement letter.

                 MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

Introduction

     The following  discussion  describes the material U.S.  federal  income tax
consequences  of the  merger to  shareholders  of Tehama  Bancorp  and  Humboldt
Bancorp.  This  discussion  is based on the Internal  Revenue  Code of 1986,  as
amended ("Code"),  Treasury Department  Regulations,  published positions of the
Internal  Revenue Service ("IRS"),  rulings,  and court decisions now in effect,
all  of  which  are  subject  to  change,   possibly  with  retroactive  effect.
Additionally,  this  discussion  is based  on  factual  representations  made by
Humboldt Bancorp and Tehama Bancorp.

     This  discussion is general in nature,  and it may not apply to some Tehama
Bancorp  shareholders.  In particular,  this  discussion  pertains only to those
Tehama Bancorp  shareholders  who hold Tehama Bancorp common stock as a "capital
asset"  (generally  property  held for  investment)  and who  report  income and
deductions  for U.S.  federal  income tax purposes on the cash (as opposed to an
accrual)  basis.  Also,  this  discussion  does not  explain all aspects of U.S.
federal income taxation that may be relevant because of your personal investment
circumstances  or because you are subject to special  provisions of U.S. federal
income tax law, such as those  applicable  to foreign  persons,  life  insurance
companies, or tax-exempt  organizations.  Furthermore,  this discussion does not
address the following topics that may be of concern to you:

     o    State, local or foreign tax laws;

     o    Estate and gift tax considerations;

     o    Tax  consequences  to Tehama Bancorp  shareholders  who received their
          Tehama  Bancorp  common stock  through  stock  options or otherwise as
          compensation.

     Since this discussion may not apply to all Tehama Bancorp  shareholders and
may not address all topics that are relevant to any particular shareholder, each
of you should  consult your own tax advisor as to the specific tax  consequences
of the merger to you because of your particular circumstances.

     An opinion  of Bartel  Eng Linn &  Schroder,  a Law  Corporation,  has been
delivered to Humboldt  Bancorp and Tehama  Bancorp which states that for federal
income  tax purposes,  under current  law, assuming  that the merger and related

<PAGE>40

transactions  will take place as described in the merger  agreement,  the merger
will  constitute a  reorganization  under Section 368 of the Code.  Assuming the
opinion is not withdrawn or changed due to changes in laws, or otherwise,  prior
to the date of the merger,  the material  federal income tax consequences of the
merger, in the opinion of Bartel Eng Linn & Schroder, will be as follows:

     o    No gain or loss will be  recognized  by  Tehama  Bancorp  or  Humboldt
          Bancorp in the merger;

     o    The basis and  holding  periods of the assets of Tehama  Bancorp  will
          carry over to Humboldt Bancorp;

     o    No gain or loss will be  recognized  by the holders of Tehama  Bancorp
          common stock upon their receipt of Humboldt  Bancorp common stock upon
          conversion of their Tehama Bancorp common stock;

     o    The receipt of cash in lieu of fractional  share interests of Humboldt
          Bancorp  common stock by holders of Tehama  Bancorp  common stock will
          result in gain or loss equal to the difference between the payment and
          the tax basis allocated to their fractional  share interests.  Whether
          the gain or loss will constitute capital gain or loss for a particular
          shareholder will depend upon whether that shareholder's Tehama Bancorp
          common stock is held as a capital asset at the date of the merger;

     o    The receipt of cash upon exercise of dissenters'  rights by holders of
          Humboldt  Bancorp  common  stock or Tehama  Bancorp  common stock will
          result in gain or loss equal to the difference between the payment and
          the tax  basis  of  their  shares.  Whether  the  gain  or loss  shall
          constitute  capital  gain or loss for a  particular  shareholder  will
          depend upon whether that  shareholder's  Humboldt Bancorp common stock
          or Tehama  Bancorp common stock is held as a capital asset at the date
          of the merger,  and whether the  requirements of Section 302(b) of the
          Code are met in the shareholder's exchange;

     o    The tax basis of Humboldt Bancorp common stock received by the holders
          of Tehama  Bancorp  common  stock will be the same as the tax basis of
          the Tehama Bancorp common stock converted in the merger; and

     o    The holding  period of Humboldt  Bancorp  common stock in the hands of
          the  shareholders  of Tehama  Bancorp will  include the period  during
          which the Tehama  Bancorp  common  stock  converted  in the merger was
          held,  provided the Tehama  Bancorp common stock was held as a capital
          asset on the date of the merger.

     In developing its opinion, Bartel Eng Linn & Schroder relied upon facts and
presentations  provided  to it  by  Humboldt  Bancorp's  management  and  Tehama
Bancorp's  management  and made no  independent  determination  of the facts and
representations.  The  representations  that Humboldt  Bancorp's  management and
Tehama Bancorp's management made were factual in nature. In addition, Bartel Eng
Linn & Schroder's  opinion was based upon the analysis of the current Code,  the
Treasury  Department  Regulations,  IRS  rulings,  and  current  case  law.  The
foregoing are subject to change, and any change may be retroactively  effective.
If so,  Bartel Eng Linn &  Schroder's  opinion  may be  affected  and may not be
relied upon.  Bartel Eng Linn & Schroder assumes no responsibility to update its
opinion  after the date of the  merger  because  of such  change.  Further,  any
variations or differences in the facts of  representations,  for any reason, may
affect Bartel Eng Linn & Schroder's  opinion,  perhaps in an adverse manner, and
make it inapplicable.

      RIGHTS OF DISSENTING TEHAMA BANCORP AND HUMBOLDT BANCORP SHAREHOLDERS

     If a  shareholder  of Tehama  Bancorp  votes against the merger or abstains
from voting, he or she is entitled to dissenters' rights under Chapter 13 of the
California  General  Corporation Law ("Chapter 13").  Because  Humboldt  Bancorp
common stock is listed on the Nasdaq National Market, dissenters' rights will be
available to the  shareholders  of Humboldt  Bancorp only if the holders of five
percent (5%) or more of Humboldt Bancorp common stock make a written demand upon
Humboldt  Bancorp  for the  purchase of  dissenting  shares in  accordance  with
Chapter 13. With respect to Humboldt Bancorp, if this condition is satisfied and
the merger is consummated, shareholders of Humboldt Bancorp who dissent from the
merger,  and with respect to Tehama Bancorp,  shareholders of Tehama Bancorp who
dissent from the merger by complying  with the  procedures  set forth in Chapter
13,  would be  entitled to receive an amount  equal to the fair market  value of
their shares as of September 19, 2000, the day before the public announcement of
the  merger.  Chapter 13 is  reprinted  in Appendix D to this  document,  and is
incorporated by this reference.

     The following  discussion is a summary and not a complete  statement of the
law relating to dissenters'  rights.  A dissenting  shareholder of either Tehama
Bancorp or Humboldt  Bancorp  should  review  Appendix D carefully  if he or she
wishes to exercise  dissenter's  rights or if he or she wishes to  preserve  the
right to do so.  Failure to comply with the procedures in Chapter 13 will result
in the loss of dissenter's  rights.  Also, if you have a beneficial  interest in
shares of Tehama Bancorp common stock, or Humboldt  Bancorp common stock, as the
case may be,  held of record  in the name of  another  person,  like a broker or
nominee,  and you wish to  exercise  your  dissenter's  rights,  you  should act
promptly  to cause the  shareholder  of record  to follow  the steps  summarized
below.

     If  the  merger  is  completed,   a  Tehama  Bancorp  or  Humboldt  Bancorp
shareholder  who elects to  exercise  dissenters'  rights and who  properly  and
timely  perfects  his or her rights will be entitled to receive the "fair market
value," in cash, of his or her shares.  Under  California  law fair market value
will  be  determined  as of  September  19,  2000,  the  day  before  the  first
announcement  of the terms of the merger,  and will exclude any  appreciation or
depreciation in the shares caused by the merger. See "Market Prices."

     If the merger  agreement is approved at the Tehama  Bancorp  meeting and at
the Humboldt  Bancorp meeting,  Tehama Bancorp,  in the case of a Tehama Bancorp
shareholder, or Humboldt Bancorp, in the case of a Humboldt Bancorp shareholder,
will within ten days of the  approval  mail a notice to the holders of record of
shares of Tehama Bancorp common stock, or Humboldt  Bancorp common stock, as the
case  may be,  who did not vote in favor of the  merger  or who  abstained  from
voting. A holder of Tehama Bancorp common stock or Humboldt Bancorp common stock
who votes in favor of the merger  agreement  or who executes and returns a proxy
with no voting  instructions  indicated  will lose any  dissenters'  rights with
respect to those shares.

     The notice  will set forth the fair market  value  price of the  dissenting
shares  as  determined  by  Tehama  Bancorp  in the  case  of a  Tehama  Bancorp
shareholder  and  by  Humboldt  Bancorp  in  the  case  of  a  Humboldt  Bancorp
shareholder.  The notice  constitutes  an offer by Tehama  Bancorp,  or Humboldt
Bancorp,  as the  case  may be,  to  purchase  any  dissenting  shares  from the
dissenting shareholders at the price stated.

     The notice will also  briefly  describe  the  procedures  to be followed by
dissenting shareholders to pursue their dissenters' rights. Within 30 days after
the mailing  date of the  notice,  shareholders  who wish to assert  dissenters'
rights must do the following:

     o    The dissenting  shareholders  must provided written demand upon Tehama
          Bancorp,  or  Humboldt  Bancorp  as the case may be,  to pay the price
          stated in the  notice.  The  written  demand  must state the number of
          Tehama Bancorp  shares or Humboldt  Bancorp shares held and the number
          of shares which the dissenting  shareholder demands Tehama Bancorp, or
          Humboldt Bancorp as the case may be, purchase for cash and a statement
          of the amount which the dissenting  shareholder  claims to be the fair
          market  value  of the  dissenting  shares  as of the  day  before  the
          announcement of the proposed merger. That statement will constitute an

<PAGE>42

          offer by the dissenting  shareholder to sell the dissenting  shares to
          Tehama Bancorp, or Humboldt Bancorp as the case may be, at that price.

     o    The   dissenting   shareholder   must  submit   share   certificate(s)
          representing  the  dissenting  shares  to  Tehama  Bancorp  at  Tehama
          Bancorp's  principal  office or, in the case of a dissenting  Humboldt
          Bancorp shareholder,  Humboldt Bancorp at its principal office. Tehama
          Bancorp, or Humboldt Bancorp as the case may be, will stamp or endorse
          the  certificate(s)  with a statement  that the shares are  dissenting
          shares or exchange the shareholder's  certificates for certificates of
          appropriate   denomination  so  stamped  or  endorsed.  If  the  price
          contained in the notice is acceptable to the  dissenting  shareholder,
          the  dissenting  shareholder  may  demand the same  price.  This would
          constitute an acceptance by the dissenting shareholder of the offer by
          Tehama  Bancorp,  or Humboldt  Bancorp as the case may be, to purchase
          the dissenting shareholder's stock at the price stated in the notice.

     The  demand  by  holders  of  Tehama   Bancorp   common  stock  and  shares
certificates should be sent to Tehama Bancorp, 239 South Main Street, Red Bluff,
California 96080, Attention:  Mr. William P. Ellison,  President.  The demand by
holders of Humboldt Bancorp common stock and shares  certificates should be sent
to Humboldt Bancorp, 701 Fifth Street, Eureka,  California 95501, Attention: Mr.
Theodore S. Mason, President.

     If Tehama Bancorp, or Humboldt Bancorp as the case may be, and a dissenting
shareholder  agree on the price for the dissenting  shares,  Tehama Bancorp,  or
Humboldt  Bancorp  as  the  case  may  be,  must  by law  pay to the  dissenting
shareholder  the  agreed  price,  together  with  interest  at the legal rate on
judgments  from the date of the agreement  between Tehama  Bancorp,  or Humboldt
Bancorp as the case may be, and the dissenting shareholder,  within the later of
(i) 30 days after the date of the agreement, or (ii) 30 days after completion of
all conditions to the merger.  Also, Tehama Bancorp,  or Humboldt Bancorp as the
case may be, may withhold  payment until the dissenting  shareholder  surrenders
the certificates for the dissenting shares.

     If Tehama Bancorp, or Humboldt Bancorp as the case may be, and a dissenting
shareholder fail to agree on the price for the dissenting  shares or disagree as
to whether the dissenting shareholder's shares are dissenting shares, the holder
may, within six months after the notice is mailed,  file a complaint in court to
determine the price, or may intervene in any pending action brought by any other
dissenting shareholder.

     In addition,  a Tehama Bancorp  shareholder or Humboldt Bancorp shareholder
may  vote in  favor  of the  merger  agreement  as to part of his or her  shares
without jeopardizing the dissenting status of those shares not voted in favor of
the merger agreement. However, a Tehama Bancorp shareholder, or Humboldt Bancorp
shareholder as the case may be, should  clearly  specify the number of shares of
Tehama  Bancorp,  or Humboldt  Bancorp as the case may be, not voted in favor of
the merger agreement.

     Dissenting  shares  may lose their  status as  dissenting  shares,  and the
holders will lose any right to demand  payment,  if any of the  following  takes
place:

     o    the merger is abandoned.  In this event,  Tehama Bancorp,  or Humboldt
          Bancorp  as the case  may be,  will pay on  demand  to any  dissenting
          shareholder  who began  proceedings in good faith under Chapter 13 all
          necessary  expenses and reasonable  attorneys'  fees incurred in those
          proceedings;

     o    the shares are  transferred  before being submitted for endorsement or
          are surrendered for conversion into shares of another class;

     o    the dissenting  shareholder and Tehama Bancorp, or Humboldt Bancorp as
          the case may be, do not agree upon the status of the dissenting shares
          or  on  the  price  of  the  dissenting  shares,  but  the  dissenting
          shareholder  fails to file suit against  Tehama  Bancorp,  or Humboldt

<PAGE>42

          Bancorp as the case may be, or to intervene in a pending action within
          six  months  following  the date on which the notice was mailed to the
          shareholder; or

     o    the  dissenting  shareholder  withdraws  his or  her  demand  for  the
          purchase of the dissenting  shares with the consent of Tehama Bancorp,
          or Humboldt Bancorp as the case may be.

     Under the terms of the merger  agreement,  in the event that holders owning
more than 10% of the outstanding  common stock of Tehama Bancorp  exercise their
dissenter's  rights,  including  any shares of common stock of Humboldt  Bancorp
held by a Humboldt Bancorp stockholder exercising his or her dissenter's rights,
then either Tehama Bancorp or Humboldt Bancorp may terminate the agreement.

Indemnification

     Under the California  General  Corporation Law, a corporation has the power
to  indemnify  present  and former  directors,  officers,  employees  and agents
against expenses,  judgments, fines and settlements if that person acted in good
faith and in a manner the person reasonably believed to be in the best interests
of the corporation and, in the case of a criminal proceeding,  had no reasonable
cause to believe the conduct of the person was unlawful.  A corporation also has
the power to  indemnify a person who is a party to any action by or in the right
of the corporation,  against expenses  actually and reasonably  incurred by that
person in connection  with the defense or settlement of the action if the person
acted  in good  faith  and in a manner  the  person  believed  to be in the best
interests of the corporation and its shareholders.

     The  indemnification  authorized  by  the  General  Corporation  Law is not
exclusive,  and a corporation  may grant its directors,  officers,  employees or
other agents  additional rights to  indemnification.  The Articles and Bylaws of
both Tehama Bancorp and Humboldt  Bancorp  provide that each shall indemnify its
officers and directors to the fullest extent permitted under California law. For
a discussion  regarding  indemnification  of officers and  directors of Humboldt
Bancorp,   see  "Management  of  Humboldt   Bancorp  -  Limited   Liability  and
Indemnification."

Capital Stock Description

     Holders of Humboldt Bancorp and Tehama Bancorp common stock are entitled to
dividends  when,  as and if declared by Humboldt  Bancorp's or Tehama  Bancorp's
board  of  directors  out  of  funds  legally  available   therefor  subject  to
restrictions on payment of dividends imposed by the California Corporations Code
and other applicable regulatory limitations. No preferred stock is authorized in
the Humboldt  Bancorp  Articles.  Preferred  stock is  authorized  in the Tehama
Bancorp Articles, but no preferred stock is outstanding.

Shareholder Rights Plan

     Tehama  Bancorp has adopted a  shareholders  rights plan under which Tehama
Bancorp  shareholders  have the  right to  purchase  shares  of  Tehama  Bancorp
preferred stock in the event of a hostile acquisition or tender offer for Tehama
Bancorp shares. The shareholder rights plan is designed to discourage  potential
acquirers from attempting to gain control of Tehama Bancorp without  negotiating
with the board of directors. Each right entitles the holder, when and if certain
specified   takeover   activity   occurs,   to  purchase  from  Tehama   Bancorp
one-hundredth of a share of Series A Junior  Participating  preferred stock at a
price of  $55 per share. The proposed merger will not trigger  these  rights and

<PAGE>47

the rights will terminate upon completion of the merger.  Humboldt  Bancorp does
not have a shareholder rights plan.

              DESCRIPTION OF HUMBOLDT BANCORP FOLLOWING THE MERGER

     The Articles of Incorporation  and Bylaws of Humboldt Bancorp will continue
as the Articles of Incorporation  and Bylaws of Humboldt  Bancorp  following the
merger. The rights,  preferences and privileges of Humboldt Bancorp common stock
following  the merger  will be the same as those  described  above for  Humboldt
Bancorp  common stock.  Further,  it is  anticipated  that following the merger,
Humboldt  Bancorp will continue to operate the  businesses of Humboldt  Bancorp,
Humboldt  Bank,  Capitol  Valley  Bank,  Capitol  Thrift,  and  Tehama  Bank  in
substantially  the same  form as such  businesses  were  conducted  prior to the
merger.  Humboldt Bancorp  anticipates  operating Tehama Bank as a subsidiary of
Humboldt Bancorp and to maintain Tehama Bank's current locations,  president and
board members subject to the addition of two new directors  selected by Humboldt
Bancorp.

                   PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS
                     OF HUMBOLDT BANCORP AND TEHAMA BANCORP

     This   document   contains,   in   addition  to   historical   information,
"forward-looking statements." These statements are based on management's beliefs
and  assumptions,   and  on  information   currently  available  to  management.
Forward-looking  statements include statements in which words such as "expect,""
anticipate,"  "intend," "plan,"  "believe,"  "estimate,"  "consider," or similar
expressions  are used.  Forward-looking  statements are not guarantees of future
performance. They involve risks, uncertainties and assumptions,  including those
described below.  Many of the factors that will determine results are beyond our
ability to control or predict.  You are cautioned  not to put undue  reliance on
any  forward-looking  statements.  Therefore,  the information set forth in this
document should be carefully  considered when evaluating the business  prospects
of  Humboldt  Bancorp and Tehama  Bancorp on an  individual  and a  consolidated
basis.

     We will  account for the merger  using the pooling of  interests  method of
accounting.  Under this method of accounting, the recorded assets,  liabilities,
shareholders' equity, income and expenses of Humboldt Bancorp and Tehama Bancorp
are combined and reflected at their historical amounts.  Further, the pooling of
interests accounting treatment avoids the creation of goodwill in the merger and
allows us to avoid charges against future earnings from amortizing goodwill.  If
we are  unable to use the  pooling  of  interests  method of  accounting  in the
merger, either party has the right to terminate the merger.

     The Statement of Income  tables that follow  contain  information  which is
calculated  by using  "weighted  average  shares." The weighted  average  shares
calculation takes into  consideration  both the number of shares outstanding and
common share equivalents, and the length of time the shares and equivalents were
outstanding  during the period.  The weighted average shares calculation is then
used to calculate basic and diluted earnings per share.

     The  following  pro forma  financial  information  combines the  historical
financial  information  of Humboldt  Bancorp and Tehama Bancorp as if the merger
had occurred at the beginning of each period presented under the assumptions and
adjustments in the  accompanying  notes to the pro forma financial  information.
The pro forma financial information does not take into consideration operational
efficiencies  or  additional  expenses  that might have  occurred as a result of
combining the institutions. The following tables show the pro forma consolidated
condensed balance sheets of Humboldt Bancorp as if the merger had occurred as of
June 30,  2000,  and pro  forma  consolidated  condensed  income  statements  of
Humboldt Bancorp as if the merger had occurred at the beginning of the six-month
periods  ended June 30, 2000 and 1999,  and the years ended  December  31, 1999,
1998 and 1997.

     Our pro forma financial  information is not  necessarily  indicative of the
financial  position or results of operations of Humboldt  Bancorp  following the
merger as it may be in the future or as it might  have been had the merger  been
effected on the assumed dates.

     The pro forma financial  information should be read in conjunction with the
historical  financial  statements of Humboldt Bancorp and Tehama Bancorp and the
notes related thereto, presented elsewhere in this document.

(b)  Reflects  consolidation of Bancorp Financial Services, an equipment leasing
     company,  jointly  owned by Humboldt  Bancorp and Tehama  Bancorp.  Bancorp
     Financial  Services is  currently  accounted  for by  Humboldt  Bancorp and
     Tehama Bancorp using the equity method of accounting.

(c)  Humboldt  Bancorp acquired Global Bancorp on April 7, 2000. The acquisition
     was  recorded  using  the  purchase   method  of  accounting.   Since  this
     acquisition is considered  significant,  the pro forma  statement of income
     has been  adjusted  to reflect  the  acquisition  as if it  occurred at the
     beginning of the period presented.

(d)  Humboldt Bancorp and Tehama Bancorp combined earnings per share and average
     outstanding  stock and common stock  equivalents  are calculated  using the
     historical  Humboldt  Bancorp  weighted  average shares plus the historical
     Tehama Bancorp  weighted average shares adjusted by the conversion ratio of
     1.775.  Includes  640,000 shares of common stock issued in connection  with
     the Humboldt  Bancorp  stock  offering,  the proceeds of which were used to
     acquire Global Bancorp.

(e)  The pro forma  statements of income are adjusted to recognize the estimated
     decrease in earnings from the net funds used to acquire  Global  Bancorp at
     an estimated average rate earned on federal funds sold of 5.0%.

(f)  Humboldt  Bancorp acquired Global Bancorp on April 7, 2000, for $16,500,000
     payable in cash and a Humboldt Bancorp promissory note. The promissory note
     is due  January  30,  2002,  and the amount  payable  may be  decreased  or
     increased  based on events  identified in the merger  agreement.  Since the
     amount to be paid is  contingent  upon future  events,  generally  accepted
     accounting  principles  require that this  promissory note be recorded when
     the contingencies are resolved and the consideration is paid.  Accordingly,
     the  purchase   accounting   adjustments   to  record  the  Global  Bancorp
     acquisition are summarized below (dollars in thousands):

     (1)  Cash portion of price paid for Global Bancorp.

     (2)  Acquisition  of all of the  outstanding  shares  of  Global  Bancorp's
          common  stock  results  in  recording   Global  Bancorp's  assets  and
          liabilities on the books of Humboldt  Bancorp and subsidiaries and the
          elimination of Global Bancorp's stockholders' equity.

     (3)  To adjust the carrying  value of loans at Global  Bancorp to estimated
          fair value.  This amount will be  recognized as an adjustment to yield
          over the estimated  life of the related  loans.  The carrying value of
          all other assets and liabilities approximates estimated fair value.

     (4)  In this note the fair value of the net  assets  acquired  exceeds  the
          purchase price.  Accordingly,  the cost of noncurrent assets acquired,
          in the case of premises and equipment,  are adjusted  downward to zero
          and the excess is recorded as a deferred credit for negative goodwill.
          A deferred tax liability of $1,184,000 is recorded and netted  against
          deferred tax assets as a result of the tax effect of the  reduction in
          premises and equipment  and other  adjustments.  Depreciation  expense
          related to the  reduction of premises  and  equipment to zero has been
          eliminated  from the pro forma  statements.  The  deferred  credit for
          negative  goodwill will be amortized  using the  straight-line  method
          over 15 years. When the  contingencies  related to the promissory note
          are resolved and the additional  consideration is paid, the additional
          cost will first be applied  against the  deferred  credit for negative
          goodwill  with  the  excess,  if any,  used to  restore  premises  and
          equipment  to fair  value.  The  remaining  excess,  if  any,  will be
          recorded as goodwill and amortized using the straight-line method over
          15 years.

(g)  In August 1999,  Humboldt Bank acquired the deposits of two branch  offices
     of CalFed Bank.  The premium paid to acquire the deposits of  approximately
     $2,384,000 was allocated to core deposit  intangible  asset.  The estimated
     runoff of these deposits will result in  amortization of the balance of the
     core deposit  intangible asset on an accelerated basis over a period of ten
     years.  Adjustments were also made to the pro forma statements of income to
     estimate the additional interest income,  interest expense and depreciation
     expense that would result from this transaction  using an estimated average
     interest  rate  earned on federal  funds  sold of  approximately  5.0%,  an
     average  rate  paid on  deposits  of  approximately  4.9% and  depreciation
     computed  using the  straight-line  method over the estimated  lives of the
     premises and equipment acquired.

(h)  Humboldt  Bancorp issued during February 2000 $5,310,000 of trust preferred
     securities at an interest rate of 10.875%.

(i)  The acquisition of Global Bancorp was consummated  concurrent with the sale
     of 640,000 shares of Humboldt Bancorp common stock at a price of $12.50 per
     share.

<PAGE>61


(j)  These  amounts  represent  the  estimated  tax  effect of the  transactions
     described in preceding  notes computed at an incremental  combined  federal
     and state tax rate of  41.15%.  Amortization  of the  deferred  credit  for
     negative goodwill described in note (f) is not taxable.

                                   (Unaudited)

     The  following  table  shows the  selected  historical  per share  data for
Humboldt  Bancorp  and  Tehama  Bancorp,  and pro forma  consolidated  financial
information  of the merger.  The table  assumes that the merger was completed at
the  beginning  of the periods  presented,  and that each  outstanding  share of
Tehama Bancorp  common stock is converted into 1.775 shares of Humboldt  Bancorp
common stock.  All amounts have been restated for the effect of stock splits and
stock dividends  previously made by both Humboldt  Bancorp and Tehama Bancorp as
appropriate,  and the  consolidation of Bancorp Financial  Services'  operations
with Humboldt Bancorp. Also Humboldt Bancorp acquired Capitol Thrift and Loan on
April 7, 2000.  Per share data for  Humboldt  Bancorp has been  restated to give
effect to Capitol Thrift and Loan's and Bancorp Financial  Services'  operations
as if they had occurred at the beginning of the period indicated.

                          HUMBOLDT BANCORP MANAGEMENT'S
                 DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATION

     The following  management's  discussion and analysis of financial condition
and results of operations contains forward-looking statements that involve risks
and  uncertainties.  Our  actual  results  could  differ  materially  from those
anticipated  in these  forward-looking  statements  as a result  of the  factors
described in the section entitled "Risk Factors" and elsewhere in this document.

General

     Humboldt  Bancorp's  results of operation are primarily  dependent upon the
results of operations of Humboldt Bank,  Capitol Valley Bank, Capitol Thrift and
Loan and, to a lesser  extent,  Bancorp  Financial  Services.  Humboldt Bank and
Capitol  Valley  Bank  conduct  general  commercial  banking  business,  such as
gathering  deposits  from the  general  public and  applying  those funds to the
origination of loans for commercial,  consumer and residential purposes. Capitol
Thrift and Loan is a California  industrial  loan company and primarily  derives
its revenues from the making of loans. Bancorp Financial Services makes consumer
automobile loans and commercial equipment leases of generally less than $100,000
to small businesses.

     Humboldt Bancorp's  profitability  depends on net interest income, which is
the difference between interest income generated by interest-earning assets, and
interest expense incurred on interest-bearing  liabilities.  Net interest income
is affected by the difference ("interest rate spread") between rates of interest
earned on interest-earning assets and rates of interest paid on interest-bearing
liabilities,  as well as the  relative  amounts of  interest-earning  assets and
interest-bearing   liabilities.   If  the  total  of   interest-earning   assets
approximates or exceeds the total of interest-bearing  liabilities, any positive
interest rate spread will generate net interest income.  Financial  institutions
have  traditionally  used  interest  rate  spread as a measure  of net  interest
income.  Another  indication of an institution's net interest income is its "net
yield  on  interest-earning  assets"  or "net  interest  margin,"  which  is net
interest income divided by average interest-earning assets.

     Because of the limited loan growth in the Humboldt,  Trinity and Mendocino,
California  area,  a  substantial  part of our  revenues  are also  derived from
non-interest income. Non-interest income consists primarily of fees generated by
the Merchant  Bankcard and Issuing Bankcard (Credit Card)  Departments and lease
residuals and rentals generated by the Lease Finance Department. During the year
ended  December 31, 1994,  Humboldt  Bank began to emphasize  the growth in such
fees and other income.  For the six months ended June 30, 2000,  and years ended
December 31,  1999,  1998 and 1997,  fees and other  income were $12.3  million,
$16.7 million, $9.7 million and $6.9 million, respectively. Of this growth, most
can be attributed to Humboldt Bank's Merchant  Bankcard  processing fees. During
the first six months ended June 30, 1999,  Humboldt Bank continued to reduce its
Issuing Bankcard (Credit Card)  activities.  This strategic  reduction in credit
card receivables was initiated in early 1997 due to increased competition in all
credit card issuing markets and a noticeable  trend of increased  charge-offs in
connection  with credit  card  receivables.  The focus of the  Issuing  Bankcard
(Credit  Card)  Department  is now  issuance of credit  cards to  Humboldt  Bank
customers.

     Although   Humboldt   Bancorp  has  planned  to  diversify  its  growth  of
traditional  banking  through the  establishment  of Capitol  Valley  Bank,  the
acquisition of Capitol  Thrift and Loan, and the proposed  acquisition of Tehama
Bancorp,  Humboldt Bancorp will continue to emphasize revenues from non-interest
income sources.  For example,  during 1997 Humboldt  Bancorp,  along with Tehama
Bancorp,  formed Bancorp Financial  Services.  Bancorp Financial  Services makes
consumer automobile loans and commercial equipment leases of generally less than
$100,000  to  small  businesses.   Humboldt  Bank's  Lease  Finance   Department
operations,   on  the  other  hand,  consist   principally  of  the  leasing  of
point-of-sale   terminals,   printers  for  credit  card  vouchers  and  related
equipment.  Humboldt  Bancorp  accounts for its investment in Bancorp  Financial
Services  using  the  equity  method,  in  which  only  Humboldt  Bancorp's  net
investment in Bancorp Financial  Services is accounted for on Humboldt Bancorp's
financial   statements,   rather  than  Bancorp  Financial  Services'  financial
statements  being  consolidated  with  Humboldt Bancorp's financial  statements.

<PAGE>64

Therefore,  the following  discussion does not include a detailed description of
Bancorp Financial Services'  operations.  Assuming the completion of the merger,
Bancorp  Financial  Services  financial  statements  will be  consolidated  with
Humboldt  Bancorp.  See  "Business  of  Humboldt  Bancorp  -  Bancorp  Financial
Services."

     Humboldt  Bancorp's  profitability  is also affected by such factors as the
level of non-interest expenses, the provision for loan losses, and the effective
tax rate.  Non-interest expenses consist of salaries and benefits,  fixed assets
(occupancy related expenses), and Merchant Bankcard expenses.

     Management's discussion and analysis of earnings and related financial data
are  presented  herein to assist  investors in  understanding  the  consolidated
financial  condition  and results of operations  of Humboldt  Bancorp,  Humboldt
Bank, and Capitol Valley Bank for the fiscal years ended December 31, 1999, 1998
and 1997,  and of  Humboldt  Bancorp,  Humboldt  Bank,  Capitol  Valley Bank and
Capitol  Thrift and Loan for the six months ended June 30, 2000.  In April 2000,
Humboldt Bancorp  completed the acquisition of Capitol Thrift and Loan, and also
completed  the  issuance of $8 million of common stock and $5.3 million in trust
preferred  securities.  Information related to historical  operations of Capitol
Thrift and Loan prior to its acquisition,  and the effect of the issuance of the
common stock and trust  preferred  securities are not reflected in the following
discussion.  This discussion should be read in conjunction with the consolidated
and pro forma financial  statements and related  footnotes  presented  elsewhere
herein.

Summary of Operations

     For the six months ended June 30,  2000,  net income was $2.8  million,  an
increase of 33.3% over net income of $2.1 million  earned  during the six months
ended June 30, 1999. Diluted earnings per share were $0.47 and $0.39 for the six
months ended June 30, 2000 and June 30, 1999, respectively. Annualized return on
average  assets was 1.17% for the six months ended June 30, 2000,  compared with
1.28% for the  comparable  six months in 1999. For the first six months of 2000,
annualized return on average equity was 14.34%,  compared with 14.60% during the
first six months of 1999. The increase in earnings for the six months ended June
30, 2000,  versus the comparable  period in 1999, can be attributed to growth in
earning  assets,  fee income  growth,  and  increased  customer  activity in our
Merchant Bankcard product.

     For the year ended  December  31,  1999,  net income was $4.6  million,  an
increase of 15.0% over net income of $4.0 million  earned during the same period
in 1998.  Diluted  earnings  per share were $0.83 and $0.75 for the years  ended
December 31, 1999 and 1998,  respectively.  The return on average assets for the
years ended December 31, 1999 and 1998, was 1.27% and 1.32%,  respectively.  The
return on average  equity for the years  ended  December  31,  1999 and 1998 was
15.10% and 16.02%,  respectively.  The  increase in earnings  for the year ended
December 31, 1999,  versus the prior period in 1998, can be attributed to growth
in earning assets,  fee income growth,  and increased  customer  activity in our
Merchant Bankcard product.

     Humboldt  Bancorp  reported  net income of $4.0  million for the year ended
December  31,  1998,  compared to $3.3  million for the year ended  December 31,
1997. The increase in net income is attributable to an increase of $2.8 million,
or 21.5% in net interest income, and an increase in other non-interest income of
$4.4 million,  or 54.3%. These increases were offset by an increase in provision
for loan losses of $1.3  million,  or 162.5%,  an increase in other non interest
expense of $4.1 million,  or 26.5% and an increase in provision for income taxes
of $906,000 or 56.2%. The increase in net interest income is attributable to the
substantial increase in earning assets and a slight increase in the net interest
yield.  The  increase  in  non-interest  income  is  primarily  attributable  to
substantial  increases  in the Lease  Finance,  Merchant  Bankcard,  and Issuing
Bankcard (Credit Card)  Departments'  income and to increases in service charges
on deposit accounts.  These increases were offset in part by a decrease in gains
on sale of loans and  investments.  The  increase  in  non-interest  expense  is
primarily  attributable  to  increases  in salaries  and  employee  benefits and
Merchant Bankcard  expenses.  These increases can be attributed to the continued
growth of Humboldt Bank and Humboldt  Bancorp.  These  increases  were offset in
part by a decrease in Issuing Bankcard (Credit Card)  Department  expenses.  The
increase  in provision for loan  losses is attributable to  an increase in loans

originated  by  Humboldt  Bank and an  increase  in  charge-offs  in the Issuing
Bankcard (Credit Card) Department and Lease Finance Department.

Results of Operations

     Net Interest Income

     Net interest income  represents the excess of interest income and loan fees
earned by Humboldt  Bancorp on its earning assets over the interest expense paid
on its interest  bearing  liabilities  and other  borrowed  money.  Net interest
income as a percentage of average  interest-earning assets is referred to as net
interest  margin.  The levels of  interest-earning  assets and  interest-bearing
liabilities,  as well as  changes  in  interest  rates  affect  the level of net
interest  income.  During periods of rapidly changing  interest rates,  Humboldt
Bancorp's  earnings can be  significantly  affected  because interest rates on a
substantial  amount of the earning  assets are tied to prime rate as reported in
the Wall  Street  Journal  and  therefore  tend to change  immediately,  whereas
interest  rates on  liabilities  have a  tendency  to change  more  slowly,  and
normally only upon the maturity of the liability.

</TABLE>


     Net  interest  income  for the six  months  ended  June 30,  2000 was $11.4
million, an increase of $3.4 million over the corresponding  period in 1999. The
increase in net interest  income is  attributable to an increase of $7.2 million
in income earned from interest-earning assets and an increase of $3.7 million in
expense from interest-bearing liabilities.  Interest expense increased 102.8% to
$7.3 million for the six months  ended June 30, 2000, compared to a $3.6 million

<PAGE>67

increase for the corresponding  period in 1999. The increase in interest expense
was the result of rising interest rates and increases in deposit balances.

     Total  interest-earning  assets  averaged $427.7 million for the six months
ended June 30, 2000,  compared to $313.5  million at year end December 31, 1999.
The average yield on  interest-earning  assets  increased to 8.8% during the six
months  ended June 30,  2000,  compared to 8.1% for the year ended  December 31,
1999, due to a general increase in market rates.

     Interest-bearing  liabilities averaged $327.5 million during the six months
ended June 30, 2000,  compared to $219.1  million at year end December 31, 1999.
The average cost of these liabilities increased in the six months ended June 30,
2000 to 4.5%  from 3.8% at year end  December  31,  1999.  The  average  cost of
interest-bearing  liabilities increased primarily as a result of rising interest
rates  in 2000.  In the  near-term,  management  does  not  anticipate  Humboldt
Bancorp's net interest  margins will be  significantly  impacted by  competitive
pressure for deposit accounts, although there can be no assurance that this will
not occur.

     Net  interest  income  for the year  ended  December  31,  1999,  was $16.9
million,  an increase of $1.1  million  compared to $15.8  million in 1998.  The
increase in net interest  income is  attributable to an increase of $1.7 million
in income  earned  from  interest-earning  assets  offset by an increase of $0.6
million in expense from interest-bearing liabilities. Interest expense increased
7.8% to $8.3 million for the  year-ended  December  31,  1999,  compared to $7.7
million for the year-ended  December 31, 1998. The increase in interest  expense
was  primarily  a result of  increased  volume,  which was  partially  offset by
falling interest rates.

     Total interest-earning  assets averaged $313.5 million at year-end December
31, 1999,  compared to $265.4 million at year-end December 31, 1998. The average
yield on  interest-earning  assets decreased to 8.l% for the year ended December
31, 1999, compared to 8.9% for the year ended December 31, 1998.

     Interest-bearing  liabilities  averaged $219.1 million at year-end December
31, 1999,  compared to $190.2 million at year-end December 31, 1998. The average
cost of these liabilities decreased for the year ended December 31, 1999 to 3.8%
from 4.1% at year-end  December 31, 1998.  The average cost of  interest-bearing
liabilities decreased primarily as a result of declining interest rates in 1999.

     Net interest  income for the year ended  December  31, 1998  totaled  $15.8
million,  compared with $13.0 million for the year ended  December 31, 1997. The
increase in net interest income was  attributable  to a significant  increase in
earning assets and a slight increase in net interest  yield.  The yield on loans
increased by 0.2% over the same period in 1997, and the cost of funds  decreased
0.1%.  The  reference  rate  used to  price a  significant  portion  of the loan
portfolio  at June 30, 2000,  and at December 31, 1999,  1998 and 1997 was 9.5%,
8.50%,  7.75% and  8.50%,  respectively.  Net loans  comprised  68.5% of average
earning assets at June 30, 2000,  64.1% at December 31, 1999,  66.0% at December
31, 1998, and 68.2% at December 31, 1997.

     Loan fees included in net interest  income were $693,000 for the six months
ended June 30, 2000, $983,000 for the year ended December 31, 1999, $1.4 million
for the year ended  December 31, 1998,  and $729,000 for the year ended December
31, 1997.

Provision for Loan and Lease Losses

     An  allowance  for loan and lease  losses  is  maintained  at a level  that
management  of  Humboldt  Bancorp  considers  adequate  for  losses  that can be
reasonably  anticipated.  The  allowance  is  increased by a charge to operating
expenses referred to as a provision for loan and lease losses, and is reduced by
the net loan that is  charged-off.  See "Loan Losses and Recoveries" for a table
summarizing the changes in the allowance for loan and lease losses.

<PAGE>68

     For the six months ended June 30, 2000,  management charged $1.3 million to
Humboldt Bancorp's  provision for loan and lease losses compared to $0.5 million
for the six months  ended June 30,  1999.  This was a 160.0%  increase  from the
prior year.  The increase in the provision for loan and lease losses was related
to the increase in loans outstanding.

     For the years ended December 31, 1999,  1998 and 1997,  management  charged
$1.0 million,  $2.1 million, and $773,000,  respectively,  to Humboldt Bancorp's
provision  for loan and lease  losses.  The ratio of the  allowance for loan and
lease  losses to total  loans and leases at  December  31,  1999,  1998 and 1997
equaled 1.5%, 1.6% and 1.5%,  respectively.  The decrease in the provisions from
1998 to 1999 was due to a  decrease  in leases  and  issuing  bank  credit  card
charge-offs  and  increase in  recoveries  from  issuing bank credit card charge
offs.  The increase in the  provision  from 1997 to 1998 is  attributable  to an
increase  in  loans  originated,  and an  increase  in  credit  card  and  lease
charge-offs,  and an increase in charge-offs.  The Merchant  Bancard  Department
does not include issuing bank credit card services.

</TABLE>


     Non-interest  income is primarily  derived  from  Merchant  Bankcard  fees,
service charges on deposit  accounts,  lease finance  department lease residuals
and rentals, and issuing bankcard (credit card) fees.

     During  the past four  fiscal  years,  Humboldt  Bank's  Merchant  Bankcard
Department  has increased in importance to Humboldt  Bank's  revenues.  Humboldt
Bank  offers  merchant  bankcard  services  to a variety  of  merchants  located
throughout  the  United  States,  including  first time  merchants  and small to
medium-sized  merchants  in the  retail,  telephone,  mail  order  and  Internet
commerce industries.  In general,  merchant bankcard services involve collecting
funds for, and crediting the accounts of, merchants for sales of merchandise and
services to credit card  customers.  For its services,  Humboldt Bank receives a
service  fee and  other  processing  fees.  Also,  at June 30,  2000,  and as of
December 31, 1999, 1998 and 1997, Humboldt Bank held merchant reserves primarily
in non-interest bearing accounts of $49.7 million,  $54.2 million, $47.0 million
and $33.0 million,  respectively.  See "Business of Humboldt  Bancorp - Merchant
Bankcard."

     During 1996,  Humboldt Bank  actively  pursued  credit card income  through
nationwide  secured and  unsecured  credit card  programs.  In early 1997,  this
strategy was abandoned due to a perceived increase in credit

<PAGE>69

risk  and  extreme  competition  from  major  credit  card  issuers.  Currently,
management estimates that at present levels of credit card receivables, Humboldt
Bank  makes a modest  monthly  profit net of service  expenses  and  write-offs.
Therefore,  while  Humboldt Bank intends to continue  credit card lending to its
customer base, there are no further plans to solicit credit card business beyond
its market areas.

     Non-interest  income  increased  $5.1  million,  or 58.6% for the six-month
period ended June 30, 2000,  compared to the six months ended June 30, 1999. The
principal  reason for this  increase was income  generated by Merchant  Bankcard
operations.  During the first six months of 2000,  Merchant Bankcard  operations
generated  $10.5 million in income  compared to $5.6 million for the same period
in 1999. The remainder of the increase in non-interest income for the six months
ended  June  30,  2000,  compared  to the same  period  in  1999,  is  primarily
attributable  to  service  charges  and fees which  were  partially  offset by a
decrease in net gain on sale of loans.

     Non-interest  income  increased $7.1 million,  or 56.8%, for the year-ended
December 31, 1999,  compared to the year-ended  December 31, 1998. The principal
reason for this increase was income generated by Merchant  Bankcard  operations.
During 1999,  Merchant  Bankcard  operations  generated  $13.2 million in income
compared to $6.2 million in 1998.

     Non-interest  income for 1998 totaled  $12.5  million,  an increase of $4.4
million,  or 54.3%, from $8.1 million earned in 1997. The increases for the year
ended 1998,  compared to the year ended 1997, are attributable  primarily to the
activities of the Merchant  Bankcard and, to a lesser extent,  the activities of
the Lease  Finance and  Issuing  Bankcard  (Credit  Card)  Departments,  plus an
increase in service charges on deposit accounts. The increase in gain on sale of
loans is  attributable  in part to selling some  portfolio  loans at a gain. The
decrease  in gain on sale of  investments  is  attributable  to the fact that no
investments  were sold in 1998.  Service charges on deposit  accounts  increased
$0.8 million or 61.5%,  fees and other income  increased  $2.8 million or 40.6%,
and all other non-interest income increased $0.7 million or 700.0%.

Non-Interest Expense

     Non-interest  expenses  consist  principally  of  employees'  salaries  and
benefits,  Merchant Bankcard expenses, and fixed asset (occupancy and equipment)
expenses.  Non-interest  expense  increased  $6.7  million,  or 51.5%,  to $13.0
million for the six months ended June 30, 2000, compared to $19.7 million in the
corresponding  period of 1999.  This  increase  was  primarily  due to  Merchant
Bankcard  operations  of $3.8  million,  salaries and benefits of $2.1  million,
primarily relating to increases in personnel, occupancy expenses of $0.4 million
and miscellaneous other expenses of $0.4 million. Salaries and employee benefits
represented the single largest component of non-interest expense at $7.7 million
or 39.2% as of June 30, 2000.

     Non-interest expense increased $8.9 million, or 45.4%, to $28.5 million for
the year-ended  December 31, 1999,  compared to $19.6 million for 1998. This was
due to increases in Merchant Bankcard operation expense of $4.8 million, as well
as increases in salary and employee benefits of $2.7 million, primarily relating
to the increase in personnel.  Salaries and employee  benefits  represented  the
single largest  component of non-interest  expense,  totaling $11.9 million,  or
41.7%, in 1999. Humboldt Bancorp's investments in new and expanded technology to
support  internal  services,  to ensure  Year 2000  compliance,  and to  provide
additional  technology-based  products for Humboldt  Bancorp's  customers,  also
resulted in expense increases.

     Non-interest  expense for the year ended 1998  totaled  $19.6  million,  an
increase  of $4.1  million  or 26.5%  from the year  ended  1997.  Salaries  and
employee  benefits  represented  the single  largest  component of  non-interest
expense,  totaling  $9.2  million or 46.7% in 1998 and $6.8  million or 43.9% in
1997.

     Full time equivalent  employees numbered 406, 318, 250, and 209 on June 30,
2000, December 31, 1999, 1998 and 1997, respectively.

<PAGE>70

     Fixed assets expense  increased  $448,000 or 34.8% for the six months ended
June 30, 2000,  compared to the  corresponding  period for the prior year. Fixed
assets  increased  during  the first six months  ended June 30,  2000 due to the
opening of a new  headquarters  for Capitol  Valley Bank and the  acquisition of
Capitol Thrift and Loan. Fixed assets expense increased  $312,000,  or 11.5%, to
$3.0  million  for the year ended  1999.  This  increase  can be  attributed  to
increased  maintenance  and  repairs on older  equipment  and  increased  rental
expense  partially  offset by increased  rental  income.  Fixed  assets  expense
increased  $245,000  or 9.9% to $2.7  million  for the  year  ended  1998.  This
increase  can be  attributed  to  increased  maintenance  and  repairs  on older
equipment and increased  rental expense,  partially  offset by increased  rental
income.  This increase also can be partly  attributed  to  depreciation  expense
related to the purchase of an in-house computer system, a local area network and
a wide area  network,  as well as the  purchase of  furniture  and  fixtures and
leasehold  improvements at the  Garberville  Branch,  the Merchant  Bankcard and
Issuing Bankcard (Credit Card) Departments at 605 K Street, Eureka,  California,
the Cashiers  Department  at 555 H Street,  Eureka,  California,  and  increased
maintenance and repairs on older equipment.

     Other expenses  (excluding salaries and employee benefits and fixed assets)
increased $4.2 million or 68.9% for the six months ended June 30, 2000, compared
to the six months ended June 30, 1999, increased $5.9 million, or 76.6%, in 1999
from 1998, and increased $1.5 million or 24.2% in 1998 from 1997,  primarily due
to the Merchant  Bankcard program and the Issuing Bankcard (Credit Card) program
in 1999 and 1998.

     The following table  summarizes the significant  components and percentages
of  non-interest  expense for the years ended December 31, 1997,  1998, 1999 and
the six months ended June 30, 1999 and 2000:

Provision for Income Taxes

     The  provision  for income  taxes for the  six-month  period ended June 30,
2000, was $1.4 million,  representing an effective tax rate of 33.3% compared to
$1.0 million, or 32.3% for the six-month period ended June 30, 1999.

     The combined  effective tax rates of 33.3%,  33.3%,  38.5% and 32.3% during
the six months ended June 30, 2000,  and for the years ended  December 31, 1999,
1998 and 1997, respectively, on reported income was below the expected statutory
federal  rate of 34.0%  and the  state  franchise  tax rate of 7.1%  (net of the
federal benefit) principally because of exemptions for Enterprise Zone loans for
state tax purposes, exemptions for municipal obligations  for federal  purposes,

low income housing tax credits,  bank owned life  insurance and other  permanent
differences.

Investments

     Humboldt  Bancorp invests excess funds in a variety of instruments in order
to meet  liquidity  and  profitability  goals.  A portion of available  funds is

invested in investment  securities including U.S. Treasury and Agency securities
such as  collateralized  mortgage  obligations  ("CMOs"),  tax-exempt  municipal
bonds, corporate bonds, and Federal Home Loan Bank and Federal National Mortgage
Corporation stock.

     At June 30, 2000, Humboldt Bancorp's portfolio of investment  securities at
fair value totaled $103.6 million,  a decrease of $11.8 million  compared to its
December  31,  1999,  securities  portfolio of $115.4  million,  representing  a

</TABLE>


     At June 30, 2000, and December 31, 1999,  1998 and 1997,  Humboldt  Bancorp
had no  concentration  of loans which  exceeded 10% of total loans not otherwise
identified by the categories set forth above.

     Real Estate - Construction

     Humboldt Bancorp makes loans to finance the construction of residential and
commercial   properties  and  to  finance  land   acquisition  and  development.
Construction   and   development   loans  are   obtained   principally   through
solicitations by Humboldt Bancorp and through  continued  business from builders
and  developers who have  previously  borrowed from Humboldt  Bancorp.  When the
total amount of a loan would otherwise  exceed Humboldt  Bancorp's legal lending
limit,  Humboldt  Bancorp  sells  participation  interests  to  other  financial
institutions to facilitate the extension of credit.

<PAGE>74

     As of June 30, 2000,  the  breakdown of  construction  loans was as follows
(dollars in thousands):

        Owner-occupied single family construction            $12,715
        Owner-occupied commercial construction                $1,759
        Speculation construction                              $2,053
        Acquisition/development                              $12,629


     Humboldt  Bancorp's   owner-occupied   single  family   construction  loans
typically  have a maturity of up to nine  months,  are secured by deeds of trust
and  usually do not exceed 80% of the  appraised  value of the home to be built.
All owner-occupied single family construction  borrowers have been pre-qualified
for long-term loans using Fannie Mae underwriting guidelines.

     Humboldt  Bancorp also makes loans to developers,  primarily in its service
area, for the purpose of acquiring  unimproved  land and  developing  such land.
These loans  typically have a maturity of 12 to 24 months,  have a floating rate
tied to prime rate as reported in the Wall Street Journal, usually do not exceed
75% of the  appraised  value,  are  secured by a first deed of trust and, in the
case of corporations, are personally guaranteed. Loan commitment and origination
fees of 0.5% to 1% are usually charged.

     All commercial construction loans are underwritten using the estimated cash
flow the secured real  property  would  provide in the event of a default by the
borrower.  A debt coverage ratio of 1.25:1 is required.  In all cases,  Humboldt
Bancorp pre-approves a long-term loan to pay off the construction loan.

     Risks  associated  with  real  estate   construction  loans  are  generally
considered higher than risks associated with other forms of lending.  Loan funds
are advanced upon the security of the project under construction,  which is more
difficult to value prior to the  completion  of  construction.  Should a default
occur which results in foreclosure, Humboldt Bancorp could be adversely affected
in that it would have to control the  project and attempt  either to arrange for
completion of construction or to dispose of the unfinished project.

     Humboldt  Bancorp's  underwriting  criteria  are  designed to evaluate  and
minimize  the risk of each  construction  loan.  A wide  variety of factors  are
carefully  considered  before  originating a  construction  loan,  including the
availability  of permanent  financing to the borrower  (which may be provided by
Humboldt  Bancorp at market  rates),  the  reputation  of the  borrower  and the
contractor,    independent   valuations   and   reviews   of   cost   estimates,
preconstruction  sale information and cash flow projections of the borrower.  At
the time of Humboldt Bancorp's  origination of a construction loan to a builder,
the builder  often has a signed  contract  with a purchaser  for the sale of the
to-be-constructed  house,  which, by assuring the builder of a repayment source,
lessens  Humboldt  Bancorp's  underwriting  risks on the  construction  loan. To
reduce the risks inherent in construction  lending,  Humboldt Bancorp limits the
number of properties which can be constructed on a "speculative" or unsold basis
by a builder at any one time to two to four houses and  requires the borrower or
its principals personally to guarantee repayment of the loan. Moreover, Humboldt
Bancorp controls certain of the risks  associated with  construction  lending by
requiring  builders  to submit  itemized  bills to Humboldt  Bancorp,  whereupon
Humboldt  Bancorp  disburses the builder's loan funds directly to the contractor
and  subcontractors,  rather  than  to the  builder.  For a  contractor  meeting
specific criteria, loan funds may be disbursed directly to the contractor.

     Real Estate - Owner-Occupied, Single-Family Residential

     Humboldt Bancorp has historically been and continues to be an originator of
owner-occupied, single-family, residential real estate loans in its market area.
These residential  loans, as a percentage of total net loans  outstanding,  were
20.8% at June 30, 2000,  20.1% at December 31, 1999,  18.9% at December 31, 1998
and 17.3% at December 31, 1997. The decrease in residential real estate loans in
2000, 1998 and 1997 is attributable to the sale of portfolio  loans.  The higher
volume of residential  real estate loans in 1999 is  attributable to lower rates
at the beginning of 1999. Humboldt Bancorp also offers FHA and VA mortgage loans
in its market area, which are underwritten and closed by a correspondent lender.

<PAGE>75

     Humboldt  Bancorp  originates  owner-occupied,  single-family,  residential
fixed-rate mortgage loans at competitive  interest rates within its market area.
Generally,  Humboldt  Bancorp sells these loans in the secondary  market.  There
were,  however, no loans held for sale at June 30, 2000, and fixed-rate loans of
$2.1 million for sale at December  31,  1999,  $7.7 million for sale at December
31, 1998, and $48,000 for sale at December 31, 1997. These balances are included
in Real Estate - Residential totals in the table above.

     Humboldt Bancorp also offers  adjustable-rate  residential  mortgage loans.
The  adjustable-rate  loans currently  offered by Humboldt Bancorp have interest
rates which adjust  every one,  three or five years from the closing date of the
loan or on an annual basis commencing after an initial fixed-rate period of one,
three or five years in accordance with a designated index.

     The  retention of  adjustable-rate  loans in Humboldt  Bancorp's  portfolio
helps reduce Humboldt Bancorp's exposure to increases or decreases in prevailing
market interest rates. However,  there are unquantifiable credit risks resulting
from potential  increases in costs to borrowers in the event of upward repricing
of adjustable-rate loans. In addition,  there can be no assurance that yields on
Humboldt  Bancorp's  adjustable-rate  loans will fully adjust to compensate  for
increases in Humboldt Bancorp's cost of funds.

        Humboldt Bancorp evaluates both the borrower's ability to make principal
and interest  payments and the value of the property  that will secure the loan.
Humboldt Bancorp originates residential mortgage loans with loan-to-value ratios
of up to 95%. On any mortgage loan exceeding an 80%  loan-to-value  ratio at the
time  of  origination,  however,  Humboldt  Bancorp  requires  private  mortgage
insurance in an amount intended to reduce Humboldt  Bancorp's exposure to 80% of
the appraised value of the underlying collateral.

     Residential  mortgage  loan  originations  come from a number  of  sources,
including  solicitations  by Humboldt  Bancorp,  referrals  by builders and real
estate brokers,  existing borrowers and depositors and walk-in  customers.  Loan
applications are accepted at all of Humboldt Bancorp's offices.

     At June 30,  2000,  Humboldt  Bancorp had  approximately  $17.4  million in
owner-occupied home equity line of credit loans, representing approximately 4.7%
of its net loan portfolio.  Humboldt  Bancorp's home equity lines of credit have
adjustable  interest rates tied to the prime  interest rate plus a margin.  Home
equity lines of credit are secured by liens against owner-occupied,  residential
real  property.  Home equity loans are  generally  limited so that the amount of
such loans, along with any senior indebtedness, does not exceed 80% of the value
of the real estate security.

     Real Estate - Commercial and Agricultural

     Humboldt  Bancorp's  commercial  real estate loan portfolio  includes loans
secured by small  apartment  buildings,  strip  shopping  centers,  small office
buildings,  farms  and  other  business  properties,  generally  located  within
Humboldt Bancorp's primary market areas.  Commercial and agricultural loans as a
percentage of total net loans  outstanding were 55.5% at June 30, 2000, 44.0% at
December  31,  1999,  43.1% at December 31, 1998 and 41.8% at December 31, 1997.
Commercial  and  agricultural  loans are  secured  by  property  of which 98% is
commercial property and 2% is agricultural property.

     Permanent  commercial  real estate  loans have a maximum  term of 10 years,
with 25-year amortization  schedules being the norm. Interest rates on permanent
loans generally  either adjust  (subject,  in some cases, to specified  interest
rate caps) at one- to five-year  intervals to specified spreads over the related
index.  Commercial real estate loans are generally  written in amounts up to 70%
of the appraised value of the property or sale price.

        Commercial  real estate loans  generally  present a higher level of risk
than loans secured by  owner-occupied,  single family  residences.  This greater
risk is due to several  factors,  including the  concentration of principal in a
limited  number  of  loans  and  borrowers,  the  effects  of  general  economic
conditions  on  income-producing  properties  and the  increased  difficulty  of
evaluating and monitoring  these types of loans.  Furthermore,  the repayment of

<PAGE>76

loans secured by  commercial  real  estate  is  typically   dependent  upon  the
successful operation of the related real estate project.

     Humboldt  Bancorp  entered  into a number of SBA  guaranteed  loans and has
loans where SBA has a subordinate  lien  position.  These loans are eligible for
sale on the secondary  market.  Humboldt  Bancorp sold SBA  guaranteed  loans in
2000, 1999 and 1998.

     Business Loans

     Humboldt  Bancorp's  commercial  loans  consist  of:  (i) loans  secured by
commercial  real  estate and (ii)  business  loans which are not secured by real
estate or if  secured by real  estate,  the  principal  source of  repayment  is
expected to be business  income.  Business  loans as a  percentage  of total net
loans outstanding were 11.8% at June 30, 2000, 17.5% at December 31, 1999, 18.3%
at December 31, 1998,  and 17.8% at December 31, 1997.  Business  loans  include
revolving lines of credit, working capital loans,  equipment financing,  letters
of credit and inventory financing.

     In recent years, Humboldt Bancorp has emphasized business lending. Humboldt
Bancorp  originates  business loans to small and medium sized  businesses in its
market  area.   Humboldt   Bancorp's  business  borrowers  are  generally  small
businesses engaged in manufacturing, distribution or retailing, or professionals
in healthcare,  accounting and law. Business loans are made generally to finance
the purchase of inventory, new or used equipment or commercial vehicles, and for
short-term  working capital.  Such loans are generally  secured by equipment and
inventory, but unsecured loans may be granted. Business loans are generally made
for terms of five years or less,  depending  on the  purpose of the loan and the
collateral,  with loans to finance operating expenses made for one year or less.
Generally,  business  loans are made in  amounts  ranging  between  $50,000  and
$300,000.

     Humboldt  Bancorp  underwrites  its  business  loans  on the  basis  of the
borrower's  cash flow and ability to service the debt from earnings  rather than
on the basis of  underlying  collateral  value,  and Humboldt  Bancorp  seeks to
structure  such loans to have more than one source of repayment.  For loans with
maturities  exceeding one year,  Humboldt  Bancorp  requires that  borrowers and
guarantors  provide updated financial  information at least annually  throughout
the term of the loan.

     Humboldt  Bancorp's  business loans may be structured as short-term  loans,
term loans or as lines of credit.  Short-term  business loans are for periods of
12 months  or less and are  generally  self-liquidating  from  asset  conversion
cycles. Business term loans are generally made to finance the purchase of assets
and have  maturities  of five  years  or less.  Business  lines  of  credit  are
typically made for the purpose of providing  short-term  working capital and are
usually  approved  with a term of 12 months and are reviewed at that time to see
if extension is  warranted.  Humboldt  Bancorp  also offers  standby  letters of
credit for its business borrowers.

     Business  loans are often  larger and may involve  greater  risk than other
types of  lending.  Because  payments  on such  loans  are  often  dependent  on
successful  operation of the business  involved,  repayment of such loans may be
subject  to a greater  extent to adverse  conditions  in the  economy.  Humboldt
Bancorp seeks to minimize these risks through its underwriting guidelines, which
require  that the loan be  supported  by  adequate  cash  flow of the  borrower,
profitability  of  the  business,  collateral  and  personal  guarantees  of the
individuals in the business.  In addition,  Humboldt Bancorp limits this type of
lending to its market area and to borrowers  with which it has prior  experience
or who are otherwise well known to Humboldt Bancorp.

     Lease Financing Loans

     Humboldt  Bancorp  makes  lease  financing  loans to finance  small  ticket
leases,  such as leases of credit card  processing  software,  terminals,  swipe
machines and related  webpages.  The dollar amount of each lease is under $2,500
and the term is  approximately  three to five years.  Lease financing loans were
$14.7  million or 4.0% of total net loans  outstanding  at June 30, 2000,  $17.2
million  or 7.6% of total net loans  outstanding  at  December  31,  1999,  $9.9
million or 5.3% of total net loans  outstanding  at December 31, 1998,  and $8.7
million  or 5.6% of total  net loans  outstanding  at  December  31,  1997.  The
increase in Humboldt Bancorp's lease financing loans in 1998 and 1997 was mostly
attributable  to an increase in credit card  equipment and leases  acquired from
Humboldt Bancorp's joint venture  subsidiary,  Bancorp Financial  Services.  The
decrease in Humboldt Bancorp's lease financing loans in 2000 and 1999 was caused
by a planned  reduction in leases  purchased  from Bancorp  Financial  Services.
However,  Humboldt  Bancorp may  continue in the future to purchase  leases from
Bancorp Financial Services.

     Credit Card and Related Accounts

     Humboldt  Bank offers  credit card loans  through  its  participation  as a
Principal  Member  of Visa.  Management  believes  that  providing  credit  card
services  helps  Humboldt  Bank  remain  competitive  by offering  customers  an
additional service.

     During  1996,  Humboldt  Bank began to actively  pursue  credit card income
through  nationwide  secured and unsecured credit card programs.  In early 1997,
this  strategy  was  abandoned  due to a  perceived  increase in credit risk and
extreme  competition  from major  credit  card  issuers.  Currently,  management
estimates that at present levels of credit card receivables, Humboldt Bank makes
a modest monthly profit net of service expenses and write-offs. Therefore, while
Humboldt  Bank intends to continue  credit card  lending to its  customer  base,
there are no further  plans to solicit  credit card  business  beyond its market
areas.  Credit card loans were $3.1  million at June 30,  2000,  $3.5 million at
December  31,  1999,  $5.7  million at December  31,  1998,  and $7.1 million at
December  31,  1997.  Credit  card  loans as a  percentage  of total  net  loans
outstanding  were 0.8% at June 30,  2000,  1.5% at December  31,  1999,  3.1% at
December 31, 1998 and 4.5% at December 31, 1997. The rate  currently  charged by
Humboldt Bank on its credit card loans ranges from 13.9% to 19.8%,  and Humboldt
Bank is permitted to change the interest  rate on 30 days notice.  Processing of
bills and  payments  is  contracted  to an outside  service.  At June 30,  2000,
Humboldt  Bank had a  commitment  to fund an aggregate of $8.7 million of credit
card loans, which represented the aggregate credit limit on credit cards.

     Consumer Loans

     The consumer loans originated by Humboldt Bancorp include  automobile loans
and  miscellaneous  other consumer loans,  including  unsecured loans.  Consumer
loans as a percentage of total net loans outstanding were 0.6% at June 30, 2000,
0.9% at December  31,  1999,  1.1% at December 31, 1998 and 1.6% at December 31,
1997.  Humboldt  Bancorp has recently  centralized its consumer loan process and
plans to continue to expand this type of loan within its market area.

     Loan Servicing

     Humboldt  Bancorp sells the majority of the mortgages and some of the Small
Business Administration loans it originates to institutional investors. However,
it retains the  servicing on these loans in order to generate  ongoing  revenues
and  to  retain  local  customer  relationships.  Humboldt  Bancorp's  servicing
portfolio in which it has sold  ownership  but retains the  servicing was $172.5
million,  $163.7 million and $144.5 million at June 30, 2000, December 31, 1999,
and December 31, 1998, respectively.

     Loan servicing  includes (i)  collecting and remitting loan payments,  (ii)
accounting  for principal and interest,  (iii) holding  escrow and impound funds
for payment of taxes and insurance,  (iv) making  inspections as required of the
mortgage  premises,  (v)   collecting   amounts   from   delinquent   mortgages,

<PAGE>

(vi)  supervising  foreclosures in the event of unremedied  defaults,  and (vii)
generally administering the loans for investors to whom they have been sold.

     Humboldt  Bancorp's fees for servicing  mortgage loans range generally from
 .250% to .375% per annum on the declining  principal  balances of the loans. The
average  service fee collected by Humboldt  Bancorp was .250% for the six months
ended June 30, 2000, and .250% for the year ended  December 31, 1999.  Servicing
fees are  collected  and  retained by Humboldt  Bancorp out of monthly  mortgage
payments.  Humboldt  Bancorp's  servicing  portfolio  can be  reduced  by normal
amortization and prepayment or liquidation of outstanding  loans.  Approximately
90% of the loans  serviced  by Humboldt  Bancorp  have  outstanding  balances of
greater than $100,000 and approximately 10% are adjustable rate mortgages.

     Humboldt  Bancorp  accounts  for  revenue  from  the  sale of  loans  where
servicing is retained in  conformity  with the  requirements  of  Statements  of
Financial  Accounting  Standards No. 125. Accounting for Transfers and Servicing
of Financial Assets and Extinguishment of Liabilities.  Humboldt Bancorp records
an asset representing the right to service loans for others when it sells a loan
and retains the servicing  rights.  The total cost of  originating or purchasing
the loans is allocated between the loan and the servicing rights, based on their
relative fair values.  Fair value is estimated by discounting  estimated  future
cash flows from the  servicing  assets  using  discount  rates that  approximate
current market rates and using current  expected future  prepayment  rates.  The
servicing  rights  are  amortized  in  proportion  to,  and over the  period of,
estimated net servicing income, assuming prepayments.

     In general, the value of Humboldt Bancorp's loan servicing portfolio may be
adversely  affected  as mortgage  interest  rates  decline and loan  prepayments
increase. This would also decrease income generated from Humboldt Bancorp's loan
servicing   portfolio.   This  negative  effect  on  Humboldt  Bancorp's  income
attributable  to  existing  servicing  may  be  offset  somewhat  by a  rise  in
origination and servicing income  attributable to new loan  originations,  which
historically have increased in periods of low mortgage interest rates.

        The following  table sets forth the dollar amount of Humboldt  Bancorp's
mortgage loan servicing portfolio. Although Humboldt Bancorp intends to continue
to increase its servicing portfolio,  increases will depend on market conditions
and the availability of capital.

</TABLE>

     Humboldt  Bancorp  also  services  a  portfolio  of  SBA  loans,  which  is
anticipated  to  increase  during 2000 as a result of an increase in selling and
marketing  efforts.  As of June 30, 2000,  SBA Loans  originated and serviced by
Humboldt Bank were $5.6 million and as of December 31, 1999, were $4.1 million.

     For the most part, the Small Business  Administration loans are tied to the
prime rate,  and as a result there is less risk of  prepayment  due to declining
rates as compared with fixed rate real estate loans.

     Loans  shown  above with  maturities  greater  than one year  include  $5.8
million of floating interest rate loans and $35.8 million of fixed rate loans.

     Humboldt  Bancorp's  renewal policy is that all maturing loans are reviewed
on a  case-by-case  basis,  new  financial  statements  are  requested  from the
borrower and an in-depth  credit  analysis is performed after which the loan may
be extended, renewed,  restructured or demand made for payment in full depending
upon the circumstances.

Loan Losses and Recoveries

     Humboldt  Bancorp  maintains  an  allowance  for loan and lease losses at a
level that management of Humboldt Bancorp considers adequate for losses that can
be reasonably anticipated.

     The Issuing Bankcard (Credit Card)  Department's  allowance for losses also
constitutes  a portion of Humboldt  Bancorp's  allowance.  The Issuing  Bankcard
(Credit Card)  Department was established in 1996. The Issuing  Bankcard (Credit
Card)  Department's  allowance at June 30, 2000, and December 31, 1999, 1998 and
1997, was $168,000 or 2.7%, $186,000 or 5.8%, $330,000 or 10.8%, and $278,000 or
11.7% of the total  allowance.  The increase in Issuing  Bankcard  (Credit Card)
Department's  allowance from 1997 to 1998, both as to amount and as a percentage
of the total  allowance,  is attributable to the Issuing  Bankcard (Credit Card)
Department's  increase in the number of credit card accounts.  Since early 1997,
Humboldt Bank has focused on its customer base for issuing Humboldt  Bank credit

<PAGE>80

cards.  Accordingly,  the allowance for losses for the Issuing  Bankcard (Credit
Card)  Department at June 30, 2000, has decreased from the allowance at December
31, 1999 and 1998.

     The adequacy of the  allowance for loan and lease losses is measured in the
context of several key ratios and factors  discussed  below.  The  allowance  is
increased  by a charge to operating  expenses and is reduced by net  charge-offs
which are loans  actually  removed  from the  consolidated  balance  sheet after
netting out  recoveries on previously  charged-off  assets.  Humboldt  Bancorp's
policy is to  charge-off  loans when,  in  management's  opinion,  the loan or a
portion thereof is deemed uncollectible,  although concerted efforts are made to
maximize recovery.  Humboldt  Bancorp's  historical net loan and lease losses or
recoveries stem from Humboldt Bancorp's  underwriting and collection  practices,
and the quality of the loan portfolio.

     During the first six months of 2000, loan charge-offs net of recoveries was
$452,000,  a 66.2% increase in loan  charge-offs  net of recoveries  compared to
$272,000  during the six months ended June 30, 1999. This increase is the result
of  recoveries  in 1999  and not an  increase  in  charge-offs,  which  actually
decreased  in the first six  months of 2000.  Charge-offs  recorded  for the six
months ended June 30, 2000, were consistent with Humboldt  Bancorp's  historical
experience in view of the growth of the loan portfolio.  Management  expects its
current loan  underwriting,  oversight and  collection  policies to promote high
quality loans and to limit loan losses. These policies include aggressive action
to limit credit losses.  As part of these policies,  Humboldt  Bancorp has hired
additional  staff and  engaged  consultants  to  support  credit  administration
functions.  Therefore,  management  expects net  charge-offs  as a percentage of
average  outstanding loans for the year 2000 will be comparable to that of prior
years.

     For the years ending  December 31, 1999,  1998,  1997,  1996 and 1995, loan
charge-offs net of recoveries were $747,000, $1.4 million,  $548,000,  $255,000,
and $255,000, respectively. These amounts represented 0.4%, 0.8%, 0.4%, 0.2% and
0.3%,  respectively,  of average  loans  outstanding.  The  decrease  in 1999 is
attributable to reduced lease and credit card  charge-offs and increased  credit
card recoveries. The increase from 1997 to 1998 is attributable to credit cards,
lease and real estate.  The increase from 1996 to 1997 is attributable to credit
cards.

     The  following  table  summarizes  the  changes in the reserve for loan and
lease losses for the periods shown:

</TABLE>

     The adequacy of the  allowance for loan and lease losses is measured in the
context  of  several  key ratios  and  factors  including:  (1) the ratio of the
allowance to total outstanding loans, (2) the ratio of total nonperforming loans
to total loans,  and (3) the ratio of net  charge-offs  (recoveries)  to average
loans outstanding.  Additional factors considered in establishing an appropriate
allowance  include  a  careful  assessment  of the  financial  condition  of the
borrower,  a realistic  determination  of the value and  adequacy of  underlying
collateral, the condition of the local economy and the condition of the specific
industry  of the  borrower,  comprehensive  analysis of the levels and trends of
loan categories,  and a review of delinquent and classified loans.  Management's
evaluation  is based on a system  whereby  each loan is  "graded" at the time of
origination,  extension or renewal.  Each grade is assessed a risk factor, which
is calculated to assess the adequacy of the allowance for loan losses.  Further,
management considers other factors including changes in the nature and volume of
the loan portfolio,  overall portfolio quality,  loan concentrations,  trends in
the  level of  delinquent  and  classified  loans,  specific  problem  loans and
commitments, and current and anticipated economic conditions.

     Since 1995,  Humboldt  Bancorp's  ratio of the allowance for loan and lease
losses to total  loans and  leases  has ranged  from 1.4% to 1.6%.  The  amounts
provided  by these  ratios  have  been  sufficient  to fund  Humboldt  Bancorp's
charge-offs,  which have not been historically  significant,  and to provide for
potential  losses as the loan  portfolio  has grown.  From 1995 through June 30,
2000,  nonperforming  loans to total  loans have  ranged from a low of 0.3% to a
high of 1.5%. For the five years ended December 31, 1999, net charge-offs ranged
from .2% to .8% of average loans.

     On a  monthly  basis,  management  considers  the  factors  that  follow in
establishing Humboldt Bancorp's Allowance for Loan and Lease Losses. The results
are reported to the board of directors on a quarterly basis.

     o    Management  considers whether there have been any significant  changes
          in Humboldt Bancorp's policies and procedures,  including underwriting
          standards and collections, charge-offs and recovery practices.

     o    Management keeps abreast of the local economic and business conditions
          through the board of directors and various organizations.

     o    Management  considers any major changes regarding the lending officers
          and staff.

     o    Humboldt  Bancorp  obtains  quarterly  outside credit reviews for loan
          write-ups and grade changes.

     o    The Loan Review/Compliance  Department reviews a sampling of loans not
          covered  by the  quarterly  outside  review  and  reports to the Chief
          Credit Officer on a monthly basis.

<PAGE>82

     o    Management   prepares   concentration   reports  in  which  loans  are
          segregated to better manage the portfolios.

     o    On a limited  basis,  Humboldt  Bancorp  will extend the maturity of a
          loan if it is awaiting  current customer  financial  statements or for
          valid  reasons.  Renewals and  extensions are not granted for the sole
          purpose of keeping a loan current.

     o    On  a  regular  basis,   management  compares  Humboldt  Bancorp  loan
          portfolios to its peer group in various categories.

     The following table represents the allocation of the allowance for loan and
lease losses as of December 31, 1999,  1998, 1997, 1996 and 1995, and as of June
30, 2000, respectively.

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

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

Non-Performing Assets

     Humboldt  Bancorp's  policy is to recognize  interest  income on an accrual
basis unless the full  collectibility  of principal  and interest is  uncertain.
Loans  that are  delinquent  90 days or more,  unless  well  secured  and in the
process of  collection,  are placed on  nonaccrual  status on a cash basis,  and
previously  accrued  but  uncollected   interest  is  reversed  against  income.
Thereafter, income is recognized only as it is collected in cash. Collectibility
is determined by considering  the  borrower's  financial  condition,  cash flow,
quality of  management,  the existence of collateral or guarantees and the state
of the local economy.

     The  increase  in  non-performing  assets  at June 30,  2000,  compared  to
December 31, 1999,  is due to  increases  in all  categories  as a result of the
acquisition of Capitol Thrift and Loan.

     The table  below  shows the gross  interest  income  that  would  have been
recorded  at June 30,  2000,  and  December  31,  1999,  if these loans had been
current  in  accordance  with  their  original  terms  and had been  outstanding
throughout  the period or if new for part of the period since  origination;  and
the amount of interest  that was  included  in net income for the period.  There
were no restructured loans 90 days past due at December 31, 1999, or at June 30,
2000.

Potential Problem Loans

     At June 30,  2000  and  December  31,  1999,  there  were no loans or other
interest bearing assets  classified for regulatory  purposes as loss,  doubtful,
substandard or special  mention that: (i) represented or resulted from trends or
uncertainties  which  management  anticipates  could have a  material  impact on
future operating results,  liquidity or capital  resources,  or (ii) represented
material  credits or assets about which  management had  information  that would
cause  serious  doubt as to the  ability  of the  borrower  to  comply  with the
repayment terms.

</TABLE>


     Total deposits  increased from the year ended December 31, 1999, to the six
months ended June 30, 2000, by $125.5 million, or 33.1%, and from the year ended
December 31, 1998,  to the year ended  December 31, 1999, by $94.7  million,  or
33.4%.  The primary reason for this increase during the first six months of 2000
is to the  acquisition  of Capitol Thrift and Loan, and during 1999 the purchase
of two  CalFed  branches,  with  deposits  totaling  $72.2  million.  Management
attributes  the  remaining  increase to  Humboldt  Bancorp's  ongoing  marketing
efforts.  Changes  occurred  in  all  deposit  categories:  non-interest-bearing
deposits increased by 15.8%, interest-bearing demand deposits decreased by 4.4%,
savings accounts increased by 44.3%, and time deposits increased by 56.1%.

     At December 31, 1998,  total deposits were $284.0  million,  an increase of
$28.8  million or 11.3% from total  deposits of $255.2  million at December  31,
1997.  Deposit growth in 1998 was due primarily to internal  growth and not as a
result of acquisitions.

     Non-interest-bearing  demand deposits continued to be a significant portion
of Humboldt  Bancorp's  deposit  base. To the extent  Humboldt  Bancorp can fund
operations with these  deposits,  net interest  spread,  which is the difference
between interest income and interest  expense,  will improve.  At June 30, 2000,
non-interest bearing demand deposits accounted for 25.4% of total deposits, down
from   29.2%  as  of   December   31,   1999.   In   general,   the   number  of
non-interest-bearing  demand accounts has been primarily from  acquisitions  and
our Merchant  Bankcard  operations.  Merchant reserves are a source of funds and
are held in the event the  merchant's  customer  returns a purchased item and is
charged-back  with the return.  See  "Business  of  Humboldt  Bancorp - Merchant
Bankcard."

     Interest-bearing  deposits  consist  of  money  market,  savings,  and time
certificate accounts.  Interest-bearing account balances tend to grow or decline
as Humboldt  Bancorp adjusts its pricing and product  strategies based on market
conditions,  including  competing  deposit  products.  At June 30,  2000,  total
interest-bearing  deposit  accounts were $376.1  million,  an increase of $108.0
million,  or 40.3%,  from  December  31,  1999.  At  December  31,  1999,  total
interest-bearing  accounts were $268.1 million, an increase of $81.0 million, or
43.3%, from December 31, 1998.  Interest-bearing  demand accounts increased $2.4
million, or 4.8%, from December 31, 1997 to 1998.

<PAGE>85

     At June 30,  2000,  time  certificates  of  deposit  in excess of  $100,000
totaled $90.2 million, or 17.9% of total outstanding deposits, compared to $68.1
million,  or 18.0%, of total  outstanding  deposits at December 31, 1999,  $46.5
million, or 16.4% of total outstanding  deposits at December 31, 1998, and $40.6
million, or 15.9%, of total outstanding  deposits at December 31, 1997. Humboldt
Bancorp has never had brokered deposits.  All public-entity time certificates of
deposit are from local  government  agencies  located in  Humboldt,  Trinity and
Mendocino Counties.

     The majority of  certificates  of deposit in  denominations  of $100,000 or
more in the  past  have  tended  to  mature  in less  than  one  year.  However,
management can give no assurance that this trend will continue in the future.

     The following  table sets forth,  by time  remaining to maturity,  all time
certificates of deposit accounts outstanding at June 30, 2000.

Shareholders' Equity

     Shareholders' equity increased $10.1 million or 29.6% during the six months
ended June 30, 2000.  Shareholders'  equity at June 30, 2000,  was $44.3 million
compared to $34.1  million at  December  31,  1999.  This is an increase of $6.3
million or 22.7% compared with $27.8 million at December 31, 1998,  which was an
increase of $4.2 million or 17.8%  compared  with the $23.6  million at December
31, 1997.

     The increase in the six months ended June 30, 2000, reflects net income and
comprehensive  income of $2.6 million,  $0.1 million in exercised stock options,
and $7.4  million net of  expenses  through  the  issuance of 640,000  shares of
common stock in an offering.

Asset-Liability Management and Interest Rate Sensitivity

     The  operating  income  and net  income  of  Humboldt  Bancorp  depend to a
substantial  extent on "rate  differentials,"  i.e., the difference  between the
income  Humboldt  Bancorp  receives  from loans,  securities  and other  earning
assets,  and the  interest  expense it pays on deposits  and other  liabilities.
Interest income and interest expense are affected by general economic conditions
and by competition in the marketplace.  Humboldt  Bancorp's interest and pricing
strategies are driven by its  asset-liability  management  analysis and by local
market conditions.

     Humboldt  Bancorp seeks to manage its assets and  liabilities to generate a
stable  level of earnings in response to changing  interest  rates and to manage
its  interest  rate  risk.   Humboldt  Bancorp  further  strives  to  serve  its
communities   and   customers   through   deployment   of  its  resources  on  a
corporate-wide  basis so that  qualified  loan  demands  may be funded  wherever
necessary in its branch  banking  system.  Asset/liability  management  involves
managing the  relationship  between  interest rate sensitive assets and interest
rate sensitive liabilities.

     The interest rate sensitivity of Humboldt Bancorp is measured over time and
is based on Humboldt  Bancorp's  ability to reprice its assets and  liabilities.
The difference between the amount of assets and liabilities repriced at the same
time is referred to as the "gap." This gap represents the risk, or  opportunity,
in repricing.  In addition to the volumes of assets and  liabilities  repricing,
two other factors create interest rate risk; how much each rate type will change
by (e.g. money market deposit account rates change less than prime) and how soon
it will reprice.  Humboldt Bancorp is somewhat asset sensitive and its near term
performance could be enhanced by rising rates and negatively affected by falling
rates due mainly to the significant amount of earning assets tied to prime.

     Interest  Rate Risk.  The table  below  shows the  potential  change in NIM
(before  taxes) if rates  change as of June 30, 2000.  NIM is the "net  interest
margin" which is the spread or difference  between  interest-earning  assets and
interest-paying  liabilities.  Humboldt Bancorp's NIM tends to increase if rates
rise,  and tends to decline if rates fall.  The cause of this exposure is due to
Humboldt  Bancorp's  concentration  of short-term and rate sensitive loans as of
June 30, 2000.

     Economic Risk.  Humboldt  Bancorp also measures the potential change in the
net present value of Humboldt  Bancorp's net existing  assets and liabilities if
rates  change (the  "economic  value of equity" or "EVE").  The table below also
shows the EVE. The EVE is  determined  by valuing  Humboldt  Bancorp  assets and
liabilities as of June 30, 2000,  using a present value cash flow calculation as
if Humboldt Bancorp is liquidated.  The EVE declines when rates increase because
there are more fixed rate assets than liabilities.  However,  Humboldt Bancorp's
NIM earnings  would also  increase as rates  increased  (from the interest  rate
risk) and this benefit would offset the decline in EVE.

     Although the gap  position is negative  during the next year as of June 30,
2000,  management  believes that Humboldt  Bancorp is somewhat  asset  sensitive
based on Humboldt  Bancorp's interest rate simulation model and has a reasonable
interest rate risk. The net interest margin should increase  slightly when rates
increase and shrink somewhat when rates fall. This is because this interest rate
risk is driven by concentration  of rate sensitive  variable rate and short-term
commercial  loans,  one of Humboldt  Bancorp's  major business  lines.  Humboldt
Bancorp does have a significant  amount of fixed rate loans to offset the impact
from  repricing of short-term  loans.  However,  there can be no assurance  that
fluctuations  in  interest  rates  will not have a  material  adverse  impact on
Humboldt Bancorp.

     Historically,  Humboldt  Bancorp's  asset rates  change more  quickly  than
deposit rates, and management feels Humboldt  Bancorp's asset yields will change
more than cost of funds when rates change.

Liquidity

     Humboldt  Bancorp's   liquidity  is  primarily  a  reflection  of  Humboldt
Bancorp's  ability to acquire funds to meet loan demand and deposit  withdrawals
and to service other  liabilities as they come due. Humboldt Bancorp has adopted
policies to  maintain a  relatively  liquid  position to enable it to respond to
changes in the financial  environment and ensure  sufficient funds are available
to meet those needs.  Generally,  Humboldt  Bancorp's major sources of liquidity
are customer deposits, sales and maturities of investment securities, the use of
federal funds markets, and net cash provided by operating activities.  Scheduled
loan repayments are a relatively  stable source of funds,  while deposit inflows
and unscheduled loan prepayments,  which are influenced by general interest rate
levels,  interest rates available on other  investments,  competition,  economic
conditions  and other  factors,  are not.  Liquid asset  balances  include cash,
amounts   due  from  other   banks,   federal   funds   sold,   and   securities
available-for-sale.  To augment liquidity,  Humboldt Bancorp has a Federal Funds
borrowing arrangement with two correspondent banks totaling $11.0 million.

     Additionally,  Humboldt  Bancorp is a member of the Federal Home Loan Bank,
and through its membership has the ability to pledge  qualifying  collateral for
short term (up to six  months)  and  long-term  (up to five  years)  borrowings.
Management may use this facility to fund loan advances by pledging single-family
residential   mortgages  and/or  commercial  real  estate  loans  as  qualifying
collateral.

(1)  Liquid  assets  include  cash  and due  from  banks,  federal  funds  sold,
     interest-bearing deposits and market value of available-for-sale securities
     less book value of pledged securities.

(2)  Less pledged public deposits.

     The  liquidity   ratios  reflect   merchant   reserves  held  primarily  in
non-interest  bearing accounts to fund  charge-backs to Humboldt Bank's Merchant
Bankcard  Department's  merchants and the pledging of  investments  for selected
deposits and current VISA and MasterCard pledging requirements.

     The decrease in liquidity at June 30, 2000,  compared to December 31, 1999,
is mainly  attributable  to the  acquisition of Capitol Thrift and Loan in April
2000. The increase during 1999 is primarily  attributable  to deposits  acquired
from the CalFed  branch  purchase  acquisitions.  The  decrease in  liquidity at
December 31, 1998,  compared to December 31, 1997, is mainly attributable to the
pledging of  investments  for selected  deposits and current Visa and MasterCard
pledging requirements.

     The analysis of liquidity also includes a review of the changes that appear
in the  consolidated  statements of cash flows for the six months ended June 30,
2000.  The statement of cash flows includes  operating,  investing and financing
categories.  Operating  activities include net income of $2.8 million,  which is
adjusted for non-cash items and increases or decreases in cash due to changes in
certain assets and liabilities.  Investing  activities consist primarily of both
proceeds  from and purchases of  investments,  the impact of net growth in loans
and the acquisition of Capitol Thrift and Loan. Financing activities present the
cash flows  associated  with  deposit  accounts,  changes in borrowed  funds and
common stock transactions.

     Part  of  Humboldt   Bancorp's  normal  lending  activity  involves  making
commitments to extend credit.  One risk associated with the loan  commitments is
the demand on Humboldt  Bancorp's  liquidity  that would result if a significant
portion  of the  commitments  were  unexpectedly  funded at one  time.  Humboldt
Bancorp assesses the likelihood of projected  funding  requirements by reviewing
historical  patterns,  current and forecasted economic conditions and individual
client  funding  needs.  At June 30, 2000 and December 31, 1999,  1998 and 1997,
Humboldt  Bancorp had $90.1  million , $75.5  million,  $59.7  million and $47.2
million, respectively, in undisbursed commitments. Further, management maintains
unpledged U.S.  Government  securities  that are available to secure  additional
borrowings in the form of reverse  repurchase  agreements.  At June 30, 2000, no
U.S.  Government  Treasuries  or Agencies  at market  value were  available  for
reverse repurchase  agreements.  However,  Humboldt Bancorp had U.S.  Government
Agency CMOs at market value of approximately $40.0 million which were unpledged.
Management  believes  that this  provides  Humboldt  Bancorp with the  necessary
liquid  assets  to  satisfy  funding  requirements  in  the  unlikely  event  of
substantially higher than projected customer funding requirements.

Trust Preferred Securities

     During March 2000,  Humboldt  Bancorp formed a Delaware  business trust for
the purpose of issuing $5,310,000 of 10.875% junior subordinated debt securities
commonly referred to as trust preferred  securities.  Trust preferred securities
are a hybrid form of a security  which is  considered  debt,  with interest paid
deductible  for income tax purposes,  but is considered  Tier 1 capital for bank
regulatory purposes. The trust preferred securities were issued to institutional
investors.  The junior  subordinated debt securities  underlying trust preferred
securities  are due in the  year  2030,  and  interest  is  paid  semi-annually.
Beginning  in March  2010 and  thereafter,  we may  redeem  the trust  preferred
securities  based on a  declining  premium  of the  stated  value  of the  trust
preferred securities.  The trust preferred securities are guaranteed by Humboldt
Bancorp.  Proceeds from the trust preferred  securities were used to enhance the
capital structure of Humboldt Bank.

Common Stock Offering

     On March 29, 2000,  Humboldt Bancorp completed a public offering of 640,000
shares of its common stock at $12.50 per share, providing gross proceeds of $8.0
million before offering  expenses of approximately  $519,000.  Proceeds from the
offering were used to enhance the capital structure of Humboldt Bancorp.

Humboldt Bank Plaza

     On June 30,  1998,  Humboldt  Bank  purchased  from an  unaffiliated  party
approximately  29  acres of  property  located  at 2500  Sixth  Street,  Eureka,
California  95501.  The property was purchased as a site for the future Humboldt
Bank Plaza at a cost of approximately $2.9 million.

     Humboldt  Bank is working with an architect and a  construction  company to
renovate the building and the parking lot so that all of Humboldt  Bancorp's and
Humboldt Bank's  administrative  offices and departments  will be located at the
facility.  Further, 20,090 square feet of the Plaza has been renovated at a cost
of $1.2 million and has been leased to the District  Attorney's  Family  Support
Division, a Humboldt County agency.  During the initial year of the lease to the
agency, monthly lease income will be $27,122.

     Humboldt  Bancorp is internally  financing the cost of the  acquisition and
the  renovation.  Based on the final  budget  approved,  the  estimated  cost to
renovate the building to house the  administrative  offices and  departments  is
approximately $3.9 million. Humboldt Bancorp believes it will save approximately
$188,000  per year in lease  expenses  and become more  efficient by housing all
administrative offices in one building. In addition, Humboldt Bancorp expects to
sell its current property at 6th & G Streets, Eureka, California.

Capital Resources

     The Federal  Reserve Board and the Federal  Deposit  Insurance  Corporation
have  established  minimum  requirements  for capital  adequacy for bank holding
companies and nonmember banks. The requirements  address both risk-based capital
and leveraged  capital.  The  regulatory  agencies may establish  higher minimum
requirements  if, for example,  a corporation  has previously  received  special
attention or has a high susceptibility to interest rate risk.

     In connection  with the formation of Capitol Valley Bank, and in connection
with the acquisition of Capitol Thrift and Loan,  Humboldt Bank,  Capitol Valley
Bank and  Capitol  Thrift and Loan are  required to  maintain  certain  leverage
ratios. See "Business of Humboldt Bancorp - Capital Adequacy Guidelines."

Effects of Inflation

     Assets and liabilities of financial  institutions are principally  monetary
in nature.  Accordingly,  interest rates,  which generally move with the rate of
inflation,  have a  potentially  significant  effect on Humboldt  Bancorp's  net
interest income.  Humboldt Bancorp attempts to limit inflation's impact on rates
and net income margins through a continuing asset/liability management program.

Impact of Recent Accounting Pronouncements

     In June 1998, the Financial  Accounting  Standards  Board  ("FASB")  issued
Statement of Financial  Accounting  Standards ("SFAS") No. 133,  "Accounting for
Derivative  Instruments  and Hedging  Activities."  This  statement  establishes
accounting and reporting  standards for derivative  instruments  and for hedging
activities.  SFAS No. 137, issued June 1999, defers the required  effective date
of SFAS No. 133 to all fiscal  quarters of fiscal years beginning after June 15,
2000.

     In June 2000,  the FASB  issued SFAS No. 138,  "Accounting  for  Derivative
Instruments  and Certain  Hedging  Activities."  SFAS No. 138 is an amendment to
SFAS No. 133 that is intended to add  comprehensive  guidance on accounting  for
derivatives  and hedging  activities.  The effective date for an entity that has
not adopted SFAS No. 133 before June 15, 2000, is  concurrent  with the adoption
of SFAS No. 133 or no later than January 1, 2001.  The adoption of SFAS Nos. 133
and 138 are not expected to have a material  impact on the financial  statements
of Humboldt Bancorp.

     In  April  2000,  the  FASB  issued  FASB   Interpretation  No.  (FIN)  44,
"Accounting  for  Certain   Transactions   involving  Stock   Compensation:   an
Interpretation  of APB Opinion No. 25." This seeks to interpret the  application
of APB 25,  especially in relation to modifications to the terms of stock awards
and the scope of APB 25. When FIN 44 affects awards and modifications made after
December 15, 1998, but before July 1, 2000, the effect of applying FIN 44 should
only be recognized  on a prospective  basis.  No  additional  compensation  cost
measured on the initial  application of FIN 44 that is  attributable  to periods
prior to July 1, 2000,  should be  recognized  and,  therefore,  no  adjustments
should  be made to  financial  statements  for  periods  prior to July 1,  2000.
Adoption of FIN 44 is not  expected to have a material  impact on the  financial
statements of Humboldt Bancorp.

                          BUSINESS OF HUMBOLDT BANCORP

Introduction

     Humboldt   Bancorp  is  a   multi-bank   holding   company  with  two  bank
subsidiaries,  Humboldt Bank and Capitol Valley Bank,  and a thrift  subsidiary,
Capitol  Thrift and Loan. In  addition, Humboldt Bancorp  owns a 50% interest in

<PAGE>91

Bancorp  Financial  Services,  a  leasing  corporation.  Reference  to  Humboldt
Bancorp,  Humboldt Bank, Capitol Valley Bank and Capitol Thrift and Loan in this
section is reference to just Humboldt  Bancorp,  Humboldt  Bank,  Capitol Valley
Bank and Capitol Thrift and Loan, respectively.

     Humboldt Bancorp was incorporated under the laws of the state of California
on January 23, 1995. Humboldt Bancorp initially was organized for the purpose of
becoming the holding  company for Humboldt Bank. On January 2, 1996, the plan of
reorganization  was  effected and shares of Humboldt  Bancorp  common stock were
issued to the  shareholders of Humboldt Bank in exchange for their Humboldt Bank
common stock. Humboldt Bank was incorporated as a California state-licensed bank
on March 13,  1989,  and began its  operations  in the  Eureka/Humboldt  area of
California  on  September  13, 1989.  Capitol  Valley Bank was  incorporated  on
December 17, 1998, and began its operations as a California  state-licensed bank
in  Roseville,  California  on  March  3,  1999.  Capitol  Thrift  and Loan is a
California industrial loan corporation that was acquired on April 7, 2000.

     In addition to its main branch located in Eureka, California, Humboldt Bank
has nine branches located in Humboldt,  Trinity and Mendocino counties.  Capitol
Valley Bank has one main branch  office  located in  Roseville,  California,  20
miles  from  downtown  Sacramento.  Capitol  Thrift  and Loan has nine  branches
located in Northern,  Central and Southern  California and focuses  primarily on
consumer  mortgage  and  commercial  real  estate  lending.   Bancorp  Financial
Services,  a California  corporation,  is jointly owned by Humboldt  Bancorp and
Tehama Bancorp and makes automobile loans to consumers and commercial  equipment
leases of less than $100,000 to small  businesses.  Bancorp  Financial  Services
markets its automobile  products primarily in California but its equipment lease
products are marketed nationally.

     As of June 30, 2000,  Humboldt  Bancorp had total assets of $575.3 million,
total deposits of $504.1  million,  and  shareholders'  equity of $44.3 million.
Humboldt  Bancorp's  net income for the six months ended June 30, 2000,  and the
year ended  December 31, 1999 was $2.8 million and $4.6  million,  respectively,
which was Humboldt  Bancorp's ninth consecutive year of increasingly  higher net
income. For the six months ended June 30, 2000 and year ended December 31, 1999,
Humboldt Bancorp's return on average assets was 1.2% and 1.3%, respectively, and
return on average equity was 14.3% and 15.1%, respectively. Since the year ended
December 31, 1995,  Humboldt Bancorp has increased annual earnings by an average
of 20.3% per year and  maintained  return on average assets at 1.2 %. During the
same period,  Humboldt  Bancorp has achieved a return on average  equity greater
than 14.5% in each year while maintaining high asset quality.

     From its  origins  as a  one-branch  bank in Eureka,  California,  Humboldt
Bancorp has grown primarily  through acquiring  branches,  opening new branches,
creating Capitol Valley Bank,  acquiring  Capitol Thrift and Loan, and expansion
of new business lines.  Humboldt Bank opened its first office in 1989 in Eureka,
California,  and  acquired  its  next  branch  in 1991 in  Fortuna,  California.
Humboldt  Bank then acquired  five of its branches  from U.S.  Bank:  Arcata and
McKinleyville in 1993 and Loleta, Weaverville and Willow Creek in 1995. In 1997,
Humboldt Bancorp acquired its Garberville  branch from First Nationwide Bank. On
August 27, 1999,  Humboldt  Bank  completed the  acquisition  of two branches of
CalFed located in Eureka and Ukiah.  Management believes the branch acquisitions
have strengthened  Humboldt Bank's market position by increasing our presence in
our primary region of Humboldt and Trinity  counties.  Humboldt Bancorp plans to
open two new branches in Eureka,  Henderson Center and Eureka High School in the
last quarter of 2000.

     In order to strengthen its market  position in Capitol Valley Bank's market
area of Roseville,  California, in September 1999, Humboldt Bancorp acquired the
stock and services of the key executives of Silverado Merger Corporation,  which
was Silverado Bank, a bank in organization in Roseville,  California.  Silverado
was in the  process of raising  the  necessary  capital to open as a  commercial
banking institution.

     Management of Humboldt Bancorp has historically  searched for and developed
non-traditional  business lines for the company.  An example of this is Humboldt
Bancorp's 50% joint  venture,  Bancorp  Financial  Services,  formed in 1996. In
addition to making  automobile loans and commercial  equipment  leases,  Bancorp
Financial  Services  acquires  leases and contracts,  which are then packaged as
asset-backed securities for placement in the public securities  market.  Another

<PAGE>92

example is Humboldt  Bank's  merchant  bankcard  services  business line.  These
services involve  collecting funds for, and crediting the accounts of, merchants
for sales of merchandise and services to credit card customers. This department,
including ATM activities,  has grown significantly since 1993, is now staffed by
110 employees,  and had total revenue of $10.5 million for the six-month  period
ended June 30, 2000.

     A further  example is the  acquisition  in April 2000 of Capitol Thrift and
Loan, an industrial  loan  corporation  with branch  locations in Napa,  Covina,
Fresno,  Lancaster,  Lodi,  Riverside,  Roseville,  Sacramento  and  San  Diego,
California.  Capitol Thrift and Loan focuses  primarily on consumer mortgage and
commercial real estate lending.

Lending Activities

     Humboldt  Bancorp  concentrates  its  lending  activities  in real  estate,
commercial,  lease  financing,  credit  card and  consumer  loans,  made  almost
exclusively to  individuals  and  businesses  primarily in Northern  California.
Humboldt  Bancorp has no foreign loans.  The net loan and lease  portfolio as of
June 30, 2000, and December 31, 1999, totaled $370.3 million and $225.1 million,
respectively, which represented 73.5% and 59.5%, respectively, of total deposits
and 64.4% and  53.1%,  respectively,  of total  assets.  Humboldt  Bancorp  also
generates fee income by servicing mortgage loans. See "Loan Servicing" below.

     Real Estate Loans and Real Estate Banking Operations

     Real Estate - Construction

     Humboldt Bancorp makes loans to finance the construction of residential and
commercial  properties and to finance land acquisition and development.  At June
30,  2000,  and  December  31,  1999,  Humboldt  Bancorp  had  outstanding  real
estate-secured   construction   loans   totaling   $29.2  and   $22.1   million,
respectively, representing 7.9% and 9.8%, respectively of Humboldt Bancorp's net
loan  portfolio.  The large  increase is a result of increased  loan activity at
Capitol Valley Bank.

     Humboldt   Bancorp's   owner-occupied   single-family   construction  loans
typically have a maturity of up to nine months and are secured by deeds of trust
and usually do not exceed 80% of the appraised value of the home to be built.

     Loans to  developers  for the  purpose  of  acquiring  unimproved  land and
developing such land into one-to-four improved residential lots typically have a
maturity  of 12 to 24  months,  have a  floating  rate tied to the  prime  rate,
usually do not exceed 75% of the appraised value, are secured by a first deed of
trust and  require  the  borrower  or its  principals  to  personally  guarantee
repayment  of the loan.  To also  reduce  the  risks  inherent  in  construction
lending,   Humboldt  Bancorp  limits  the  number  of  properties  that  can  be
constructed on a  "speculative"  or unsold basis by a builder at any one time to
two to four houses.

     Commercial   construction  loans  are  underwritten  using  the  actual  or
estimated  cash flow the secured real  property  would provide to an investor in
the event of a default by the borrower.  A debt  coverage  ratio of 1.25:1 and a
maximum loan to value of 70% are required in most cases.

     Real Estate - Owner-Occupied, Single-Family Residential

     Humboldt Bancorp also originates owner-occupied, single-family, residential
real estate  loans in its market  area.  At June 30, 2000 and December 31, 1999,
Humboldt Bancorp had outstanding owner-occupied, single-family, residential real
estate loans totaling $59.2 and $45.2 million,  respectively.  Humboldt  Bancorp
originates  fixed-rate mortgage loans and adjustable-rate  residential  mortgage
loans.  Fixed-rate mortgages are at competitive rates and adjustable-rate  loans
currently  offered by Humboldt  Bancorp have  interest  rates which adjust every
one, three or five years from the closing date of the loan or on an annual basis
commencing  after an  initial fixed-rate  period of one,  three  or  five  years

<PAGE>93

in  accordance  with a  designated  index,  plus a stipulated  margin.  Humboldt
Bancorp originates residential mortgage loans with loan-to-value ratios of up to
95%. On any mortgage loan  exceeding an 80%  loan-to-value  ratio at the time of
origination, however, Humboldt Bancorp requires private mortgage insurance in an
amount  intended to reduce Humboldt  Bancorp's  exposure to 80% of the appraised
value of the  underlying  collateral.  Also, at June 30, 2000,  and December 31,
1999, Humboldt Bancorp had approximately $17.4 and $15.7 million,  respectively,
in home equity line of credit loans,  representing  approximately 4.6% and 6.9%,
respectively,  of its gross loan portfolio. Humboldt Bancorp's home equity lines
of credit have adjustable  interest rates tied to the prime interest rate plus a
margin.

     Generally,  Humboldt  Bancorp  sells  its  owner-occupied,   single-family,
residential fixed-rate loans to institutional investors in the secondary market,
but retains the  servicing of such loans.  There were,  however,  no real estate
loans pending sale at June 30, 2000.

     Real Estate - Commercial and Agricultural

     In order to enhance the yield on and  decrease the average term to maturity
of its assets, Humboldt Bancorp originates permanent loans secured by commercial
real estate.  Humboldt Bancorp's  commercial real estate loan portfolio includes
loans secured by small apartment buildings, strip shopping centers, small office
buildings,  farms  and  other  business  properties,  generally  located  within
Humboldt  Bancorp's primary market area. Real estate commercial and agricultural
loans are secured by both  commercial and  single-family  property.  At June 30,
2000 and December 31, 1999, Humboldt Bancorp had outstanding real estate secured
commercial and  agricultural  loans  totaling  $205.4 million and $99.1 million,
respectively.  Real Estate secured by commercial and real estate loans increased
primarily due to the acquisition of Capitol Thrift and Loan.

     Business Loans

     Humboldt  Bancorp's  commercial  loans  consist  of:  (i) loans  secured by
commercial  real estate,  and (ii) business  loans which are not secured by real
estate or, if secured by real  estate,  the  principal  source of  repayment  is
expected to be business  income.  For a discussion of Humboldt  Bancorp's  loans
secured by commercial  real estate lending see " -- Real Estate - Commercial and
Agricultural." Business loans include revolving lines of credit, working capital
loans, equipment financing,  letters of credit and inventory financing.  At June
30, 2000 and at December 31, 1999 and 1998,  Humboldt Bancorp had business loans
totaling $43.6 million,  $39.3 million,  and $34.0 million  representing  11.8%,
17.5% and 18.3%, respectively, of Humboldt Bancorp's net loan portfolio.

     Typically,  business loans are floating rate  obligations  and are made for
terms of five  years  or  less,  depending  on the  purpose  of the loan and the
collateral.  No single business  customer  accounted for more than 3.0% of total
gross loans at June 30, 2000.

     Lease Financing Loans

     Humboldt  Bancorp makes lease  financing loans to finance credit card swipe
machines and other small ticket leases.  The dollar amount of each lease usually
ranges from under $2,000 to $5,000 and the term is  approximately  three to five
years.  At June 30, 2000 and  December 31, 1999 and 1998,  Humboldt  Bancorp had
outstanding  lease  financing  loans  totaling  $14.7,  $17.2 and $9.9  million,
respectively,  representing  4.0%,  7.6% and  5.3%,  respectively,  of  Humboldt
Bancorp's net loan portfolio.

     Credit Card and Related Service

     Humboldt Bank offers credit card accounts  through its  participation  as a
principal  member  of Visa.  Management  believes  that  providing  credit  card
services to its customers helps Humboldt Bank remain  competitive by offering an
additional  service.  Currently  Humboldt Bank does not actively  solicit credit
card  business  beyond its customer  base and market area.  At June 30, 2000 and
December 31, 1999 and 1998, credit card loans totaled $3.1 million, $3.5 million

<PAGE>94

and $5.7 million, or 0.8%, 1.5% and 3.1%, respectively of Humboldt Bancorp's net
loan portfolio.

     Consumer Loans

     The consumer loans originated by Humboldt Bancorp include  automobile loans
and  miscellaneous  other consumer loans,  including  unsecured loans.  Consumer
lending  affords  Humboldt  Bancorp the  opportunity  to earn yields higher than
those obtainable on  single-family  residential  lending.  At June 30, 2000, and
December 31, 1999 and 1998,  consumer  loans totaled $2.3 million,  $1.9 million
and $2.1 million,  or 0.6%, 0.9% and 1.1%,  respectively,  of Humboldt Bancorp's
net loan portfolio.

     Other Loans

     At June 30,  2000 and  December  31,  1998 and 1999,  Humboldt  Bancorp had
outstanding  other loans  totaling $3.7 million,  $1.2 million and $2.1 million.
These loans  consist  mainly of  overdrafts  of less than 30 days'  duration and
state and political loans.

     Loan Servicing

     Humboldt  Bancorp sells the majority of its mortgage  loans and most of the
Small  Business   Administration  loans  that  it  originates  to  institutional
investors. However, it retains the servicing on these loans in order to generate
ongoing revenues.  Humboldt Bancorp's servicing portfolio,  in which it has sold
ownership but retains the  servicing,  was $172.5  million,  $163.7  million and
$144.5 million at June 30, 2000, and December 31, 1999 and 1998, respectively.

Merchant Bankcard

     In 1993,  Humboldt Bank established a merchant draft  processing  operation
("Merchant Bankcard"). Since that time, the operation has grown steadily both in
volume and scope of activities.  In general,  Merchant Bankcard services involve
collecting  funds for, and  crediting  the accounts of,  merchants  for sales of
merchandise  and  services  to credit and debit  card  customers.  The  Merchant
Bankcard Department specializes in providing processing for first time merchants
and small-to  medium-sized  merchants in the retail,  telephone,  mail order and
Internet commerce industries.

     While these merchants vary in size, a typical merchant  customer  generates
approximately  $40,000  in annual  credit  card  charge  volume.  Humboldt  Bank
believes  that there is a market for  providing  Merchant  Bankcard  services to
these  merchants,  who are often  overlooked by larger banks. For the six months
ended June 30, 2000,  no one merchant  accounted  for more than 2.2% of Merchant
Bankcard's  total  gross  processing  volume.  At June 30,  2000,  the  Merchant
Bankcard  Department  provided  processing  services  to  approximately   67,720
merchants.

     The  transaction  processing  industry  provides  merchants with credit and
debit card processing  services.  The industry has grown rapidly in recent years
as a result of wider merchant acceptance and rapid technological advances within
the bankcard industry.

     Humboldt Bank markets its Merchant  Bankcard  services through  independent
service and marketing  organizations  ("ISOs").  In most cases, the ISOs solicit
merchant  accounts  and  perform  the service  and  collection  function,  while
Humboldt Bank provides the accounting and credit function.  For these functions,
Humboldt Bank receives an average  processing fee of approximately  0.15%. As of
June 30, 2000,  the three ISOs  engaged by Humboldt  Bank,  as described  above,
represented  60,645 merchant  accounts.  Further,  those three ISOs  represented
$225.0 million of total Merchant  Bankcard gross  processing  volume for the six
months ended June 30, 2000.  These three  contracts  expire in 2000,  2002,  and
2004.  During the fourth quarter of 1999, two additional  ISOs signed  contracts
for this service with Humboldt Bank.

<PAGE>95

     In 1997,  Humboldt  Bank  began an  additional  unit  within  the  Merchant
Bankcard  Department where all servicing  aspects of the  relationship  with the
merchant are performed by Humboldt Bank,  although Humboldt Bank still relies on
independent  sales  organizations  for solicitation of merchants.  Humboldt Bank
categorizes these types of accounts as proprietary accounts ("Proprietary"). For
these additional services,  Humboldt Bank is able to retain more income from the
service and  processing  fees paid than when an ISO is  involved.  For  example,
Humboldt Bank receives a service fee of approximately 4% of the gross processing
volume. For the six months ended June 30, 2000, Proprietary accounts represented
$203.5  million of total  Merchant  Bankcard  gross  volume  and 7,075  merchant
accounts at period end.  The  Proprietary  accounts  segment of Humboldt  Bank's
merchant processing portfolio is growing much more rapidly than the ISO segment.
For  example,  for the six months  ended June 30,  2000,  net  revenues  for the
Proprietary  account  segment have grown 139.0% relative to the same time period
in 1999,  while net revenues for the ISO segment have decreased 7.5% relative to
the same time period in 1999.

     Humboldt  Bancorp  intends to  continue to expand the  Proprietary  account
segment of its  business.  The rapid  acceptance  of the Internet as a method to
transact commerce has led to an increase in the number of smaller Internet-based
merchants.  Humboldt  Bank believes its  processing  services are well suited to
these lower volume  merchants.  Further,  Humboldt Bank has entered into several
key  relationships  with web site  providers and gateway  services that cater to
business  services for merchants for the purpose of advertising  Humboldt Bank's
merchant  bankcard  services.  In addition,  Humboldt  accepts  applications for
merchant    processing   services   at   its   Merchant   Bankcard   web   site,
www.merchant.humboldtbank.com.

     Many of the merchants  processing through the Merchant Bankcard  Department
accept  consumers'  credit card numbers over the telephone.  There are no signed
drafts and the entire process is handled  electronically.  Since  consumers find
these transactions easier to dispute than transactions  involving signed drafts,
the charge-back  rates for services  provided over the telephone and through the
Internet  are  generally  higher.  Further,  because most of the  merchants  are
located outside the Humboldt-Eureka, California area, they require more Humboldt
Bank  personnel to follow and monitor  their  accounts.  Humboldt Bank views its
risk management and fraud avoidance  practices as integral to its operations and
overall  success  because of Humboldt  Bank's  potential  liability for merchant
fraud,  charge backs and other losses.  While the first time and small to medium
sized  merchants may be potentially  lucrative to Humboldt Bank,  these accounts
are  perceived  high risk  because  of lack of  business  experience  and higher
monitoring  costs.  For ISO  accounts,  risk is mitigated by requiring  merchant
reserves  and by ISO  reserves and  guarantees.  Reserves are demand  deposit or
"checking"  account  balances  with minimum  required  balances  established  by
withholding a percentage of process volume. For the Proprietary account segment,
risk management and fraud control occur initially at the application  stage when
merchant  applications  are  reviewed  against  certain  criteria  to  determine
acceptance  or denial.  Furthermore,  Humboldt  Bank  addresses  these  risks by
actively  monitoring  all  merchants on a daily basis,  employing an  aggressive
fraud control team,  requiring personal  guarantees for nearly all merchants and
holding  reserve  deposits for certain  merchants.  These deposits which totaled
$56.8 million were comprised of $49.7 million in non-interest  bearing  deposits
and $7.1 million in interest-bearing deposits at June 30, 2000.

     In the event a consumer is dissatisfied with the merchandise or service, in
general,  a merchant  must accept a  charge-back  for a period of 120 days.  The
merchant's  checking account is debited with the charge-back if sufficient funds
exist;  otherwise,  the  merchant's  reserve funds are debited.  If a merchant's
reserves  are  insufficient  to fund  the  charge-back  and an ISO is  involved,
Humboldt Bank looks to the  applicable and available  guarantee,  if any, of the
ISO. If the  merchant's  reserve is exhausted  and either (i) an ISO is involved
but no  guarantee  is  applicable  or  available,  or (ii)  no ISO is  involved,
Humboldt Bank uses its internal reserves to fund the charge-back.

     Merchant bankcard  processing  services are highly regulated by credit card
associations  such as VISA. In order to participate in the credit card programs,
Humboldt  Bank  must  comply  with  the  credit  card  association's  rules  and
regulations,  which may change from time to time. In November 1999, VISA adopted
rule changes that  required  staged-in  compliance  by March 31, 2001. To become
compliant,  Humboldt Bank would have had to restrict  processing  volume because
its overall chargeback percentage was in excess of what the new rules would have

<PAGE>97

allowed.  As a result of these  regulations,  Humboldt  Bank  merchant  bankcard
income would have been reduced.  In October 2000,  VISA adopted a revised set of
rules  that are less  restrictive  than the  November  1999 rules and with which
Humboldt Bank is in full compliance.  Humboldt Bank expects to continue to be in
compliance  with  the  October  2000  regulations  going  forward  and  does not
anticipate  any  reduction  of  merchant  bankcard  income as a result of VISA's
adoption of new rules.

ATM Funding

     In 1996,  Humboldt Bank began its automated  teller machine ("ATM") funding
activities by sponsoring  several non-bank companies that place and service ATMs
in various  public places such as  restaurants,  stores,  and gas stations.  ATM
networks  such as Star,  Plus and  Cirrus  require  a  placement  company  to be
sponsored by a chartered  financial  institution.  Humboldt Bank sponsors  these
companies and provides cash for their ATMs.  Humboldt Bank contracts with bonded
money carriers and correspondent  vault centers throughout the nation to provide
a ready amount of cash when these placement companies so require.  Humboldt Bank
earns a fee for each sponsored transaction and a fee for the cash advanced.

     For the six months  ended June 30, 2000,  and for the years ended  December
31, 1999 and December 31, 1998, ATM funding was $16.8 million, $11.5 million and
$13.9 million,  respectively.  Losses related to the ATM funding  activities for
the six months  ended June 30, 2000,  and for the years ended  December 31, 1999
and December 31, 1998, were $644, $0, and $3,340, respectively.

Capitol Valley Bank

     In March 1999, Humboldt Bancorp contributed capital, totaling $4.5 million,
to form Capitol Valley Bank and an additional  infusion of capital in the amount
of $1.2  million  was made in July  2000.  Capitol  Valley  Bank is  located  in
Roseville,  California,  and opened for business March 3, 1999. Humboldt Bancorp
believes  that  the   Sacramento-Roseville,   California  market  represents  an
attractive    location   to   do   business   for   a   community    bank.   The
Sacramento-Roseville   region's   infrastructure   contains  a  major   airport,
deep-water  port,  transcontinental  railroad and an interstate  freeway system.
Roseville is located  approximately  20 miles northeast of downtown  Sacramento.
The city of  Roseville  is an important  link along the  Interstate  80 corridor
linking Sacramento and Auburn,  California and Reno, Nevada. Capitol Valley Bank
will focus primarily on products and services for individuals, professionals and
small to middle-size businesses.

     In September 1999,  Humboldt  Bancorp entered into an agreement to acquire,
for 49,502 shares of Humboldt  Bancorp  common stock and warrants to purchase up
to 99,000 shares of Humboldt  Bancorp  common stock at $10.91 per share,  all of
the  outstanding  shares of Silverado  Merger  Corporation,  which was Silverado
Bank, a bank in  organization,  which had yet to raise the necessary  capital to
open as a commercial banking institution. In the event Capitol Valley Bank fails
to achieve certain business objectives such as developing new business accounts,
Humboldt  Bancorp has the right to repurchase  the 49,502 shares of common stock
for $.91 each,  and the  warrants to  purchase  up to 99,000  shares of Humboldt
Bancorp  common stock for $10.91 per share  cannot be  exercised.  Further,  the
number  of  shares  issued  to  the  former  shareholders  of  Silverado  Merger
Corporation  are subject to adjustment  in the event  Humboldt  Bancorp  assumes
certain obligations of Silverado Merger Corporation.  As a result of the payment
of certain  obligations of Silverado  Merger  Corporation  by Humboldt  Bancorp,
Humboldt  Bancorp has reduced the number of shares to be issued by 6,963 shares.
As  part  of  the  acquisition,  Capitol  Valley  Bank  hired  Silverado  Merger
Corporation's  president and entered into  non-competition  agreements  with the
shareholders of Silverado Merger Corporation prohibiting them from participating
in any  financial  institution  within 30 miles of  Capitol  Valley  Bank  until
December 31,  2002.  In addition,  Capitol  Valley  Bank's board was expanded to
include  three  new  directors,  consisting  of some of the prior  directors  of
Silverado Merger  Corporation.  Finally,  as part of the acquisition  agreement,
some shareholders and supporters of Silverado Merger Corporation  purchased $1.6
million  of  Humboldt  Bancorp's  restricted  common  stock at $12.00  per share
pursuant to a private placement.

<PAGE>98

     Silverado Merger Corporation had no operations. Therefore, Silverado Merger
Corporation's  financial  statements are immaterial.  Humboldt  Bancorp acquired
Silverado  Merger  Corporation to expand  Capitol Valley Bank's  presence in the
Sacramento-Roseville,  California area through business  associates and contacts
of the former directors and organizers of Silverado Merger Corporation.

     As of June 30, 2000, Capitol Valley Bank had total assets of $56.0 million,
total loans of $29.5 million, and total deposits of $52.4 million.

Bancorp Financial Services

     During 1996, Humboldt Bank entered into a joint venture with Tehama Bank to
organize and share equally in a subsidiary  leasing company,  Bancorp  Financial
Services.  Bancorp Financial Services was organized as a California  corporation
on November 25, 1996,  and Humboldt Bank and Tehama Bank each  contributed  $2.0
million towards its  capitalization as of January 2, 1997.  Subsequently  during
1998,  Humboldt Bank and Tehama Bank each contributed their interests in Bancorp
Financial Services to their respective  holding companies,  Humboldt Bancorp and
Tehama Bancorp.  In March 1999, both Humboldt Bancorp and Tehama Bancorp made an
infusion of capital in Bancorp  Financial  Services of  $999,750  each.  Bancorp
Financial  Services makes  consumer  automobile  loans and commercial  equipment
leases of generally less than $100,000 to small businesses.

     In addition to making leases and loans, Bancorp Financial Services buys and
services  commercial  equipment  lease  contracts  throughout  the United States
directly from lessors, brokers, finance companies, banks and thrifts nationwide.
Bancorp Financial Services also buys and services consumer automobile  contracts
primarily  in Northern  California.  While it  maintains  its own  portfolio  of
contracts,  the  majority  of  acquired  leases  are  sold  to its  wholly-owned
subsidiary,  BFS Funding Corporation,  which packages the leases as asset-backed
securities  for  placement in the public  market on a  non-recourse  and partial
recourse basis.  Bancorp Financial Services retains the servicing and management
of all leases it acquires regardless of their subsequent sale. Likewise, Bancorp
Financial   Services  acquires  consumer   automobile   contracts  from  dealers
throughout  Northern  California and similarly  repackages and sells the payment
streams to institutional  investors in the financial marketplace while retaining
the servicing. In addition to service fees, Bancorp Financial Services generates
income through spreads on its lease portfolio,  loan portfolio,  gains on sales,
and ongoing fees and charges.

     Previously, Humboldt Bank purchased leases from Bancorp Financial Services.
In order to avoid any related  party  investments,  it is not  anticipated  that
Humboldt Bank will acquire leases from Bancorp Financial Services in the future.
In addition,  Humboldt Bank has in the past extended credit to Bancorp Financial
Services. See "Certain Relationships and Related Transactions."

     The Bancorp Financial Services board of directors consists of seven members
including  Bancorp  Financial  Services'  Chief  Executive  Officer,   Kevin  D.
Cochrane,  and two three-member  groups each  representing  Humboldt Bancorp and
Tehama  Bancorp.  Humboldt  Bancorp  has elected  Theodore  S.  Mason,  Lawrence
Francesconi  and Gary L. Evans to the board of  directors  of Bancorp  Financial
Services.

     Humboldt Bancorp accounts for its investment in Bancorp Financial  Services
using the equity  method.  For the six months ended June 30, 2000, and the years
ended  December  31,  1999 and 1998,  Humboldt  Bancorp  recognized  revenue  of
$286,000,  $450,000 and $259,000,  respectively.  Assuming  consummation  of the
merger,  Humboldt  Bancorp  will  account  for Bancorp  Financial  Services on a
consolidated basis.

     The Federal Reserve Board, FDIC and other financial institution  regulatory
agencies  have  proposed  to amend their  capital  adequacy  standards  for bank
holding companies and other financial  institutions  concerning the treatment of
residual  interests.  Residual  interests  are defined as those on balance sheet
assets that represent  interests in transferred  financial  assets retained by a
seller after transfer of the financial  assets.  For example,  Bancorp Financial
Services makes leases and loans which are then packaged and sold as asset-backed
securities  for  placement in the public  market on a  non-recourse  and partial
recourse  basis. If  the proposed  regulations  are  adopted, Bancorp  Financial

<PAGE>99

Services  would be required to retain  risk-based  capital in an amount equal to
the amount of the  residual  interest  that is retained  on the  balance  sheet.
Humboldt Bancorp is currently exploring its options including raising additional
capital for Bancorp Financial  Services or a sale of or a sale of an interest in
Bancorp Financial Services.

Capitol Thrift and Loan

     On April 7, 2000,  we acquired  Capitol  Thrift and Loan for  approximately
$16.5 million  consisting of $11.9 million in cash and the balance consisting of
a  $4.6  million  promissory  note  subject  to  adjustment.  The  $4.6  million
promissory  note  is due  January  30,  2002,  and  up to  $2.0  million  of the
promissory note may be exchanged for common stock. We funded the cash portion of
the  acquisition  through  the raising of capital  through the  issuance of $8.0
million in gross  proceeds of common  stock and  approximately  $5.3  million in
gross proceeds of trust preferred securities.

     Capitol  Thrift and Loan is a  California  corporation  licensed  under the
California  Industrial  Loan Law.  Capitol  Thrift  and Loan  conducts a general
consumer and commercial  finance business from eight branches located throughout
the State of California. At the time of the acquisition, Capitol Thrift and Loan
operated ten branches. Two branches were subsequently consolidated.

     Capitol Thrift and Loan's primary source of revenue is providing commercial
and   single-family,   residential  real  estate  loans  to  customers  who  are
predominantly small and middle-market businesses and individuals. Capitol Thrift
and Loan does not provide  general  commercial  banking  services such as demand
checking  accounts,  lines of  credit,  safe  deposit  boxes and wire  transfer.
Capitol  Thrift  and  Loan  funds  its  lending  activities  by  issuing  thrift
certificates and investment certificates.

     Capitol  Thrift and Loan has its head office located at 1424 Second Street,
Napa,  California  94559.  Capitol Thrift and Loan's  deposits are insured up to
$100,000 by the Federal  Deposit  Insurance  Corporation.  As of June 30,  2000,
Capitol  Thrift and Loan had total assets of $123.0  million,  total deposits of
$104.5  million  and net income of $38,000  for the six  months  June 30,  2000.
Subsequent to April 7, 2000,  Humboldt Bancorp  accounted for Capitol Thrift and
Loan on a consolidated basis.

     In 1996 and 1997,  Capitol Thrift and Loan  experienced an increase in loss
on real property held for sale (RPHFS) and expenses related thereto.  A majority
of the losses  related to loans  made prior to June 1992,  at which time  credit
underwriting  policies were  strengthened.  As a result of these  increases,  in
August 1998, Capitol Thrift and Loan entered into an agreement with the FDIC and
the California Department of Financial Institutions pursuant to which management
and the Capitol Thrift and Loan board of directors agreed to reduce the level of
classified  assets as outlined in the  agreement,  develop and  implement a plan
with specific  strategies  for reducing  RPHFS,  classified  and  non-performing
loans,  and revise the  methodology  for calculating the allowance for losses on
loans.  In  addition,  Capitol  Thrift and Loan is required  to maintain  Tier 1
capital of 8% or more of Capitol Thrift and Loan's adjusted total assets.  As of
June 30, 2000 Capitol Thrift and Loan's Tier 1 capital was 9.5%.  Capitol Thrift
and Loan's  management  believes that Capitol  Thrift and Loan has complied with
the provisions of the agreement.

     Further,  as  a  condition  of  the  California   Department  of  Financial
Institution's  consent to Humboldt  Bancorp  acquisition  of Capitol  Thrift and
Loan,  Capitol  Thrift and Loan is  required  to  maintain  a ratio of  tangible
shareholders' equity to tangible assets of not less than 8%. Humboldt Bank shall
maintain a ratio of tangible shareholders' equity to tangible assets of not less
than 7%. As of June 30,  2000,  the  tangible  shareholders  equity to  tangible
assets ratio was 9.01% for Capitol Thrift and Loan and 7.3% for Humboldt Bank.

Acquisition of California Federal Branches

     On August 27, 1999, Humboldt Bank completed the acquisition of two branches
located at 959 Myrtle  Avenue,  Eureka,  CA 95501,  and 607 South State  Street,
Ukiah,  CA 95482,  from CalFed.  Under  the  terms of  the  purchase  agreement,

<PAGE>100

Humboldt Bank acquired all of the fixed assets  relating to CalFed's  Eureka and
Ukiah branch offices.  Humboldt Bank primarily  acquired the two CalFed branches
for access to their deposits.  The purchase price for the two branches was equal
to  approximately  3.25% of the aggregate  deposits  acquired by Humboldt  Bank.
Total deposits  acquired by Humboldt Bank were  approximately  $72.2 million and
loans acquired were approximately $0.1 million.

Proposed Investment in a Mortgage Company

     Humboldt  Bancorp and Tehama  Bancorp  each  propose to invest  $375,000 in
17.5%  cumulative  convertible  preferred  Series  A stock  of  Central  Pacific
Mortgage Company. The convertible preferred Series A of Central Pacific Mortgage
is  convertible  at the option of  Humboldt  Bancorp  into as much as 35% of the
outstanding  shares of the voting  stock of Central  Pacific  Mortgage.  If both
Humboldt Bancorp and Tehama Bancorp convert their  convertible  preferred Series
A, they would  collectively  control as much as 70% of the outstanding shares of
voting stock of Central Pacific Mortgage.

     Central Pacific  Mortgage is a mortgage  company  headquartered  in Folsom,
California.  Central Pacific Mortgage Company  originates,  packages,  and sells
mortgage loans through a system of net branches.  Mortgage loans sold by Central
Pacific Mortgage Company are sold on a servicing  release basis. As of September
1, 2000, Central Pacific Mortgage had 93 branch offices in the United States.

     The  investment  by both  Humboldt  Bancorp  and Tehama  Bancorp in Central
Pacific  Mortgage  is  subject  to  regulatory  approval  and  entering  into  a
definitive agreement with Central Pacific Mortgage Company.

Human Resources

     At June 30,  2000,  Humboldt  Bancorp  employed  a total  of 406  full-time
equivalent employees, consisting of 174 salaried persons and 232 hourly persons.
None of Humboldt Bancorp's employees are represented by a collective  bargaining
group. Management considers its relations with its employees to be excellent.

Competition

     Humboldt  Bancorp's  primary market area consists of Humboldt,  Trinity and
Mendocino counties and nearby communities of adjacent counties. Humboldt Bancorp
has recently  entered into Placer County with the opening of Capitol Valley Bank
in Roseville, California and into Northern, Central and Southern California with
the acquisition of Capitol Thrift and Loan.

     Humboldt Bancorp actively competes for all types of deposits and loans with
other banks and financial  institutions  located in its service area,  including
credit unions,  which are able to offset more  favorable  savings rates and loan
rates due primarily to favorable tax treatment.  In California generally,  major
banks and local  regional banks dominate the  commercial  banking  industry.  By
virtue of their larger  capital  bases,  such  institutions  have  substantially
greater  lending  limits  than  those  of  Humboldt  Bancorp,  as  well  as more
locations,  more products and services,  greater  economies of scale and greater
ability  to make  investments  in  technology  for  the  delivery  of  financial
services.

     An  independent  bank's  principal  competitors  for deposits and loans are
other banks,  particularly major banks,  savings and loan  associations,  credit
unions,  thrift and loans, mortgage brokerage companies and insurance companies.
Increased  deregulation  of financial  institutions  has increased  competition.
Other  institutions,  such  as  mutual  funds,  brokerage  houses,  credit  card
companies and even retail  establishments have offered new investment  vehicles,
such as  money-market  funds,  that also  compete with banks.  The  direction of
federal  legislation in recent years favors competition  between different types
of  financial  institutions  and  encourages  new  entrants  into the  financial
services market. It is anticipated that this trend will continue.

<PAGE>101

     Humboldt Bancorp's strategy for meeting  competition has been to maintain a
sound capital base and liquidity position,  employ experienced  management,  and
concentrate  on particular  segments of the market  particularly  businesses and
professionals, by offering customers a degree of personal attention that, in the
opinion of management,  is not generally  available  through Humboldt  Bancorp's
larger   competitors.   Humboldt  Bancorp  relies  upon  specialized   services,
responsive handling of customer needs, local promotional activity,  and personal
contacts by its officers,  directors and staff, compared with large multi-branch
banks that  compete  primarily on interest  rates and location of branches.  The
acquisition  of  Capitol  Thrift  and Loan  increased  Humboldt  Bancorp's  loan
portfolio and the  continuation  of Capitol  Thrift and Loan's  industrial  loan
charter will provide favorable lending terms so as to assist Humboldt Bancorp to
compete  with  institutions  for more  loans.  No  assurance  can be given  that
Humboldt Bancorp will be able to compete  successfully for more loans.  Also, no
assurance can be given that, because of customer loyalty, available products and
services or other  reasons,  customers in Humboldt  Bancorp's  branches will not
withdraw their business and establish banking relationships with competitors.

     Historically, insurance companies, brokerage firms, credit unions and other
non-bank competitors have less regulation than banks and can be more flexible in
the products and services they offer. The Financial  Services  Modernization Act
of 1999  eliminates  most of the separation  between banks,  brokerage firms and
insurance companies by permitting securities firms and insurers to buy banks and
by permitting banks to underwrite securities and insurance.  Generally speaking,
the Act is likely to increase  competition  for community banks such as Humboldt
Bank,  Capitol  Valley  Bank and  Capitol  Thrift  and Loan,  but may also cause
consolidations  and mergers  with larger  competitors.  The  Financial  Services
Modernization Act may also increase cross-border consolidations and mergers.

Properties

     As of June 30, 2000, Humboldt Bank had nine branch offices,  Capitol Valley
Bank had one main branch, Capitol Thrift and Loan had nine branches, and Bancorp
Financial  Services  had one main  office.  In  addition,  Humboldt  Bancorp  is
consolidating its operations at one administration office.

     Rental expense for all leases of premises for the six months ended June 30,
2000, was $340,000,  and for the years ended  December 31, 1999,  1998 and 1997,
was  $401,000,  $269,000  and  $128,000,  respectively.  Rental  income from all
properties  owned and leased for the six months ended June 30, 2000, and for the
years ended December 31, 1999, 1998 and 1997, was $164,000,  $302,000,  $177,000
and $65,000, respectively.

Legal Proceedings

     On  December  7,  1998,  the case of  Freeman,  et al. v.  Citibank  (South
Dakota), N.A., et al., Civil Action No. CV-98-RRA-3029-S  ("Freeman"), was filed
in the United States  District  Court,  Northern  District of Alabama,  Northern
Division. This case is a purported class action brought on behalf of Mr. Freeman
and others similarly situated (VISA credit cardholders issued by Citibank (South
Dakota),  hereinafter  "Citibank"),  against  Citibank  and  VISA  International
(hereinafter  "VISA") to: (i) enjoin the collection of debts charged to Citibank
VISA cards for gambling at Internet casino  websites,  (ii) have Internet casino
gambling declared unlawful and (iii) recover all payments  including  principal,
interest and penalties  received by Citibank and VISA related to such debts. Mr.
Freeman is alleging that Citibank and VISA were  facilitating,  participating in
and  profiting  from  gambling by allowing Mr.  Freeman to use his Citibank VISA
card to purchase  "e-cash" at a website owned and operated by a provider of such
"virtual"  commodity  (hereinafter the "Merchant  Provider"),  which he accessed
from an on-line  casino  operation.  Mr.  Freeman  proceeded to play the game of
blackjack  with his e-cash and lost $30.  The action  alleges  violation  of the
federal  Wire  Act  and  the  federal   Racketeering   Influenced   and  Corrupt
Organizations  Act ("RICO").  Mr. Freeman is seeking treble damages  pursuant to
RICO, punitive damages and attorney's fees, in addition to compensatory  damages
and declaratory  relief.  Citibank has pending a motion to compel arbitration in
the case and the  plaintiff  has moved to  consolidate  this  action with others
which have been filed  against VISA across the country.  To date neither  motion
has been heard by the court.

<PAGE>102

     Humboldt  Bank is not a defendant in the Freeman  case.  However,  Humboldt
Bank provides merchant processing for the Merchant Provider used by Mr. Freeman,
and on April 21, 1999, Citibank sent a letter to Humboldt Bank seeking indemnity
for the Freeman action pursuant to VISA regulations.  Humboldt Bank and Citibank
have  had  preliminary  discussions  regarding  this  matter,  but at this  time
Humboldt Bank has neither  acknowledged  nor disputed the  applicability  of the
VISA  regulation  cited by Citibank.  The Freeman  action is in its  preliminary
stages and the outcome at this time cannot be determined. A similar lawsuit in a
United States  District Court in Wisconsin (not involving  Humboldt Bank insofar
as is known) was recently  dismissed;  however,  that decision is not binding on
the  Freeman  court.  Until the Freeman  action is  ultimately  determined,  any
potential  action against  Humboldt Bank by Citibank would be premature.  In the
event it is ultimately  determined  that Humboldt Bank is obligated to indemnify
Citibank,  Humboldt  Bank  intends to seek  indemnity  against both the Merchant
Provider  and the company  which,  through its  independent  marketing  efforts,
presented the Merchant Provider's  application for merchant services to Humboldt
Bank.

     On May 17, 2000, the case of Lawrence Bradley v. Visa International Service
Association and Travelers Bank USA Corp.  (Civil Action No. C 00-01777 SBA), was
filed in the United States District Court, Northern District of California. This
case is a purported  class  action  brought on behalf of Mr.  Bradley and others
similarly  situated  (holders of VISA credit  cards  issued by  Travelers  Bank,
hereinafter   "Travelers"  (although  Humboldt  Bank  believes  plaintiff  means
Citibank)),  against Travelers and VISA International  (hereinafter  "Visa") to:
(i) enjoin the collection of debts charged to Traveler's Visa cards for gambling
at  Internet  casino  websites,  (ii) have  Internet  casino  gambling  declared
unlawful,  and (iii) recover all  payments,  including  principal,  interest and
penalties,  received by Travelers and Visa related to such debts. Mr. Bradley is
alleging  that  Travelers  and  Visa  were  facilitating,  participating  in and
profiting  from gambling by allowing Mr.  Bradley to use his Travelers Visa card
to  purchase  "e-cash"  at a  website  owned and  operated  by  Cryptologic  and
Intersafe  Global,  which he accessed from seven online casino  operations.  Mr.
Bradley  proceeded to participate in certain games with his e-cash and allegedly
lost in the aggregate  $7,048.  The action alleges violation of the federal Wire
Act and the  federal  Racketeering  Influenced  and  Corrupt  Organizations  Act
("RICO").  Mr.  Bradley is seeking  treble  damages  pursuant to RICO,  punitive
damages and attorney's fees, in addition to compensatory damages and declaratory
relief.

     Humboldt Bank provided merchant  processing for Cryptologic's and Intersafe
Global's credit card operations,  and on July 3, 2000, Citibank sent a letter to
Humboldt  Bank  seeking  indemnity  for  the  Bradley  action  pursuant  to Visa
regulations.  Humboldt  Bank  and  Citibank  have  had  preliminary  discussions
regarding  this  matter,  but Humboldt  Bank has not yet  formally  responded to
Citibank's  letter.  The Bradley action is in its  preliminary  stages,  and the
outcome at this time cannot be determined. The Bradley action is very similar to
the Freeman case. In the event it is ultimately determined that Humboldt Bank is
obligated to indemnify Citibank, Humboldt Bank intends to seek indemnity against
Cryptologic,  Intersafe Global and  creditcards.com,  the company which, through
its  independent  marketing  efforts,   presented  Cryptologic's  and  Intersafe
Global's application for merchant services to Humboldt Bank.

     On June 23,  2000,  Humboldt  Bank was served  with two  lawsuits  entitled
Christopher Bradford, et. al. v. Leasecomm  Corporation,  et. al. , Commonwealth
of  Massachusetts,  Middlesex,  ss.  (Superior  Court  Civil No. 00- 2756),  and
Frances M. Okougbo, et. al. v. Leasecomm Corporation,  et. al. , Commonwealth of
Massachusetts,  Middlesex,  ss.  (Superior Court Civil No.  00-2757).  These are
purported  class  action  lawsuits  in which  plaintiffs  allege  that they were
charged excessive fees by defendants for entering into non cancellable equipment
leases and merchant  agreements in connection  with  establishing  a business in
which revenues may be received  through credit cards  payments.  In the Bradford
and  Okougbo  lawsuits,  plaintiffs  are  alleging,  among  other  things,  that
CardService International,  and creditcards.com used deceptive practices to sign
plaintiffs to merchant agreements  establishing  merchant accounts with Humboldt
Bank  and  were  charged   excessive   fees.   CardService   International   and
creditcards.com are independent service and marketing  organizations that market
Humboldt  Bank's  merchant  services.  In the  Bradford  and  Okougbo  lawsuits,
plaintiffs  are  also  alleging  that  Humboldt  Bank  was  either  an  agent of
CardService International and creditcards.com,  or CardService International and
creditcards.com  were agents of Humboldt  Bank, and that Humboldt Bank should be
jointly and  severally  liable for any damages.  Plaintiffs  in the Bradford and
Okougbo  lawsuits are seeking,  among other things, a refund of all monies paid,

<PAGE>103

including costs and interest,  and attorney's fees and multiple  damages.  These
cases are in their  initial  stages,  and Humboldt  Bank has an  indemnification
agreement with CardService  International.  Further, Humboldt Bancorp is seeking
indemnification from creditcards.com.

     We are also involved in other litigation, the outcome of which, we believe,
will not have a material effect on our operations or financial condition.

                 SUPERVISION AND REGULATION OF HUMBOLDT BANCORP

     Humboldt Bancorp and our subsidiaries,  Humboldt Bank,  Capitol Valley Bank
and Capitol  Thrift & Loan  Association  are  extensively  regulated  under both
federal and state laws and regulations. These laws and regulations are primarily
intended to protect  depositors,  not  shareholders.  The following  information
describes  statutory or  regulatory  provisions  affecting  us;  however,  it is
qualified  in  its  entirety  by  reference  to  the  particular  statutory  and
regulatory provisions at issue.

     We are a registered  bank holding  company  under the Bank Holding  Company
Act,  regulated,  supervised  and  examined by the Federal  Reserve  Bank of San
Francisco.  We must file with the  Federal  Reserve  Bank an annual  report  and
additional  reports  as the  Federal  Reserve  Board  may  require.  We are also
periodically  examined by the Federal  Reserve Board.  Humboldt Bank and Capitol
Valley Bank,  as  California  state-licensed  banks,  and Capitol  Thrift & Loan
Association, an Industrial Loan Company licensed under the California Industrial
Loans Laws, are also regulated,  supervised,  and  periodically  examined by the
California  Department  of  Financial   Institutions  and  the  Federal  Deposit
Insurance Corporation ("FDIC").

     The regulations of the Federal Reserve Board,  the FDIC, and the California
Department of Financial  Institutions govern most aspects of Humboldt Bancorp's,
Humboldt Bank's,  Capitol Valley Bank's and Capitol Thrift & Loan  Association's
businesses  and  operations,  including,  but not  limited  to, the scope of its
business,  investments,  reserves against deposits, the nature and amount of any
collateral for loans,  the time of availability of deposited funds, the issuance
of securities,  the payment of dividends,  bank  expansion and bank  activities,
including real estate  development and insurance  activities,  and the making of
periodic  reports.  Various consumer laws and regulations also apply to Humboldt
Bank,  Capitol  Valley Bank and Capitol Thrift & Loan  Association.  The Federal
Reserve Board, the FDIC, and the California Department of Financial Institutions
have broad enforcement powers over depository institutions,  including the power
to prohibit a bank from engaging in business  practices  which are considered to
be unsafe or unsound,  to impose  substantial fines and other civil and criminal
penalties,  to terminate  deposit  insurance,  and to appoint a  conservator  or
receiver under a variety of  circumstances.  The Federal  Reserve Board also has
broad  enforcement  powers over bank holding  companies,  including the power to
impose substantial fines and other civil and criminal penalties.

Regulation of Bank Holding Companies

     Our activities are subject to extensive  regulation by the Federal  Reserve
Board.  The Bank Holding Company Act requires us to obtain the prior approval of
the Federal Reserve Board before (i) directly or indirectly  acquiring ownership
or control of any voting  shares of another  bank or bank  holding  company  if,
after such  acquisition,  we would own or control  more than 5% of the shares of
the other bank or bank holding  company  (unless the acquiring  company  already
owns or controls a majority of such shares); (ii) acquiring all or substantially
all of the assets of another bank or bank holding  company;  or (iii) merging or
consolidating with another bank holding company.  The Federal Reserve Board will
not  approve  any  acquisition,  merger  or  consolidation  that  would  have  a
substantially  anticompetitive result, unless the anticompetitive effects of the
proposed  transaction  are clearly  outweighed by a greater  public  interest in
meeting the  convenience  and needs of the  community to be served.  The Federal
Reserve Board also considers capital adequacy and other financial and managerial
factors in its review of acquisitions and mergers.

<PAGE>104

     With certain  exceptions,  the Bank Holding  Company Act also  prohibits us
from acquiring or retaining direct or indirect ownership or control of more than
5% of the  voting  shares  of any  company  that is not a bank  or bank  holding
company,  or from engaging directly or indirectly in activities other than those
of  banking,  managing or  controlling  banks,  or  providing  services  for its
subsidiaries.  The principal  exceptions to these  prohibitions  involve certain
non-bank  activities  that, by statute or by Federal Reserve Board regulation or
order, have been determined to be activities  closely related to the business of
banking or of managing or controlling banks.

Federal Deposit Insurance

     The FDIC  insures  deposits of  federally  insured  banks,  savings  banks,
savings  associations and thrifts and safeguards the safety and soundness of the
banking industry.  Two separate  insurance funds are maintained and administered
by the FDIC. In general,  bank deposits are insured  through the Bank  Insurance
Fund.

     Deposits  in  savings   associations   are  insured   through  the  Savings
Association Insurance Fund ("SAIF"). A SAIF member may merge with a bank as long
as the bank  continues  to pay the SAIF  insurance  assessments  on the deposits
acquired.  Humboldt Bank continues to pay SAIF insurance assessments on deposits
acquired from CalFed and HomeFed branch  acquisitions.  The Economic  Growth and
Regulatory  Paperwork  Reduction Act as part of the Omnibus  Appropriations Bill
provided  for the  recapitalization  of SAIF  requiring  a one time  assessment,
payable on November  30,  1996,  of  approximately  65 basis  points per $100 of
deposits of SAIF insured  deposits and for years 1997 through  1999,  payment of
interest on Financing  Corporation  ("FICO")  bonds that were issued to help pay
for the clean up of the savings and loan industry.  Banks paid approximately 1.3
cents per $100 of deposits for this special  assessment  from 1997 through 1999,
and from the Year  2000,  banks  will pay  approximately  2.4  cents per $100 of
deposits until the FICO bonds mature in 2017 through 2019.

     Deposits in Humboldt Bank,  Capitol Valley Bank and Capitol Thrift and Loan
are insured to a maximum of $100,000 per  depositor  by the FDIC.  The banks and
thrifts are required to pay quarterly deposit  insurance premium  assessments to
the FDIC. In general  terms,  each  institution is assessed  insurance  premiums
according to how much risk to the  insurance  fund the  institution  represents.
Well-capitalized  institutions with few supervisory  concerns are assessed lower
premiums than other  institutions.  Currently,  insurance fund assessments range
from  zero  for   well-capitalized   institutions   to  0.27%  of  deposits  for
institutions  that are not  (with a  statutory  minimum  of  $2,000  paid by all
institutions).  Through June 30, 2000, the assessment for Humboldt Bank, Capitol
Valley  Bank and  Capitol  Thrift  and Loan was  $36,000,  $2,000  and  $12,000,
respectively.

     The FDIC may  terminate  the deposit  insurance  of any insured  depository
institution  if the FDIC  determines  that the  institution  has  engaged  or is
engaging in unsafe or unsound practices, is in an unsafe or unsound condition to
continue operations or has violated any applicable law, regulation, order or any
condition  imposed in writing  by, or pursuant to written  agreement  with,  the
FDIC. The FDIC may also suspend deposit insurance temporarily during the hearing
process for a permanent  termination  of  insurance  if the  institution  has no
tangible capital.

Capital Adequacy Guidelines

     The Federal  Reserve Board and the FDIC employ similar  risk-based  capital
guidelines in their  examination  and  regulation of bank holding  companies and
financial institutions. If capital falls below the minimum levels established by
the  guidelines,  the bank holding  company,  bank or savings bank may be denied
approval to acquire or establish  additional banks or non-bank  businesses or to
open new facilities.  Failure to satisfy  applicable  capital  guidelines  could
subject a banking  institution  to a variety of  enforcement  actions by federal
regulatory  authorities,  including the termination of deposit  insurance by the
FDIC.

     In the  calculation of risk-based  capital,  assets and  off-balance  sheet
items are assigned to broad risk  categories.  Off-balance  sheet items are also
taken into account in the calculation of risk-based capital,  with each class of
off-balance sheet item being converted to a balance sheet equivalent. From these

<PAGE>105

computations,  the total of risk-weighted assets is derived.  Risk-based capital
ratios therefore state capital as a percentage of total risk-weighted assets and
off-balance sheet items. The ratios established by guideline are minimums only.

     Current  risk-based  capital  guidelines require all bank holding companies
and banks to maintain a minimum risk-based total capital ratio equal to 8% and a
Tier 1 capital ratio of 4%. Intangibles other than readily  marketable  mortgage
servicing  rights are generally  deducted from capital.  Tier 1 capital includes
common shareholders' equity, qualifying perpetual preferred stock (within limits
and  subject to  certain  conditions,  particularly  if the  preferred  stock is
cumulative  preferred  stock),  and  minority  interests  in equity  accounts of
consolidated  subsidiaries,  less intangibles.  Tier 2 capital includes: (i) the
allowance  for  loan  losses  up to  1.25%  of  risk-weighted  assets;  (ii) any
qualifying  perpetual  preferred stock exceeding the amount includable in Tier 1
capital;  (iii) hybrid capital  instruments;  (iv) perpetual debt; (v) mandatory
convertible   securities  and  (vi)  subordinated  debt  and  intermediate  term
preferred stock of up to 50% of Tier 1 capital. Total capital is the sum of Tier
1 and Tier 2 capital,  less reciprocal  holdings of other banking  organizations
and  capital  instruments.  At  December  31,  1998 and 1999 and June 30,  2000,
Humboldt   Bancorp's  general  loan  loss  reserve  was  1.4%,  1.2%  and  1.4%,
respectively, of risk-weighted assets.

     Humboldt  Bancorp's  Tier 1  risk-based  capital  ratio at June  30,  2000,
December  31,  1999,  and  December  31,  1998,  was 10.58%,  10.90% and 11.75%,
respectively.

     The FDIC has added a market risk component to the capital  requirements  of
nonmember banks. The market risk component could require  additional capital for
general  or  specific  market  risk of  trading  portfolios  of debt and  equity
securities  and  other  investments  or  assets.  The  FDIC's  evaluation  of an
institution's  capital  adequacy  takes account of a variety of factors as well,
including interest rate risks to which the institution is subject, the level and
quality  of  an   institution's   earnings,   loan  and   investment   portfolio
characteristics  and risks,  risks  arising  from the conduct of  nontraditional
activities and other factors. Accordingly, the FDIC's final supervisory judgment
concerning an institution's capital adequacy could differ significantly from the
conclusions  that might be drawn  from the  absolute  level of an  institution's
risk-based  capital ratios.  Therefore,  institutions  generally are expected to
maintain  risk-based  capital  ratios that exceed the minimum  ratios  discussed
above.  This is particularly  true for  institutions  contemplating  significant
expansion plans and institutions  that are subject to high or inordinate  levels
of  risk.  Moreover,   although  the  FDIC  does  not  impose  explicit  capital
requirements  on holding  companies  of  institutions  regulated  by the Federal
Reserve  Bank,  the FDIC can take account of the degree of leverage and risks at
the holding  company level.  If the FDIC determines that the holding company (or
another  affiliate  of the  institution  regulated by the FDIC) has an excessive
degree of leverage or is subject to inordinate  risks,  the FDIC may require the
subsidiary  institution(s) to maintain additional capital or the FDIC may impose
limitations  on the  subsidiary  institution's  ability  to  support  its weaker
affiliates or holding company.  Humboldt  Bancorp's  risk-based capital ratio at
June 30, 2000,  December 31, 1999, and at December 31, 1998, was 11.83%,  12.07%
and 13.00%, respectively.

     The  Federal  Reserve  Board and the FDIC have also  established  a minimum
leverage  ratio  of 3%.  However,  for  bank  holding  companies  and  financial
institutions  seeking to expand and for all but the most highly  rated banks and
bank  holding  companies,  the  Federal  Reserve  Board  and the FDIC  expect an
additional  cushion  of at least 100 to 200 basis  points.  The  leverage  ratio
represents  Tier 1 capital as a percentage  of total assets,  less  intangibles.
Humboldt  Bancorp's  leverage ratio at June 30, 2000, and December 31, 1999, and
December 31, 1998, was 8.55%, 7.50% and 8.12%,  respectively.  At June 30, 2000,
December  31,  1999,  and  at  December  31,  1998,  Humboldt  Bancorp  and  its
subsidiaries were in compliance with all regulatory capital requirements.

     In order to resolve the problems of  undercapitalized  institutions  and to
prevent a recurrence  of the banking  crisis of the 1980s and early  1990s,  the
Federal Deposit  Insurance  Corporation  Improvement  Act of 1991  established a
system known as "prompt  corrective  action." Under the prompt corrective action
provisions and implementing  regulations,  every  institution is classified into
one of five  categories,  depending on (i) its total  risk-based  capital ratio,
Tier 1 risk-based  capital ratio and leverage ratio and (ii) certain  subjective
factors.  The categories  are:  "well  capitalized,"  "adequately  capitalized,"
"undercapitalized,"    "significantly    undercapitalized"    and    "critically

<PAGE>106

undercapitalized."  A financial  institution's  operations can be  significantly
affected  by  its  capital  classification.   Financial  institution  regulatory
agencies  generally  are required to appoint a receiver or  conservator  shortly
after an institution enters the category of weakest capitalization.  The Federal
Deposit  Insurance  Corporation  Improvement  Act of 1991  also  authorizes  the
regulatory  agencies to reclassify an institution from one category into a lower
category if the institution is in an unsafe or unsound  condition or engaging in
an unsafe or unsound  practice.  Undercapitalized  institutions  are required to
take certain  specified  actions in order to increase their capital or otherwise
decrease the risks to the federal deposit insurance funds.

        The following  table  illustrates the capital  guidelines  applicable to
Humboldt Bank, Capitol Valley Bank and Capitol Thrift and Loan, as well as their
total risk-based capital ratios, Tier 1 capital ratios and leverage ratios as of
June 30, 2000.

</TABLE>

     In connection with Humboldt Bancorp's  organization of Capitol Valley Bank,
Humboldt Bank has  committed to the FDIC that it will remain "well  capitalized"
and that it will  maintain  minimum Tier 1 leverage  capital  ratios of at least
6.5% for the initial 12 months of operation of Capitol Valley Bank, 6.8% for the
next 12 months,  and 7.2% for the third  12-month  period.  During the first six
months of 2000,  Humboldt  Bancorp  contributed  approximately  $1.2  million to
Capitol Valley Bank and is expected to contribute an additional  $0.5 million in
the last quarter of 2000.

     In addition,  as a condition of Humboldt  Bancorp's  acquisition of Capitol
Thrift and Loan,  Humboldt Bancorp  represented to the California  Department of
Financial  Institutions  that Capitol  Thrift and Loan will  maintain a leverage
ratio of not less than 8% and Humboldt  Bank will  maintain a leverage  ratio of
not less than 7%.

Limits on Dividends and Other Payments

     We have never paid cash dividends,  but have declared stock dividends.  Our
ability to obtain funds for the payment of cash dividends, if any, and for other
cash  requirements  is dependent on the amount of dividends that may be declared
by Humboldt  Bancorp  subsidiaries.  California bank law provides that dividends
may be paid from the lesser of  retained  earnings or net income of the bank for
its last three years.  Further,  a  California-chartered  bank may not declare a
dividend  without  the  approval  of  the  California  Department  of  Financial
Institutions if the total of dividends and distributions  declared in a calendar
year exceeds the greater of the bank's  retained  earnings or net income for its
last fiscal year or its current fiscal year.  State-chartered  banks' ability to
pay  dividends may be affected by capital  adequacy  guidelines of their primary
federal  bank  regulatory  agency as well.  See "Capital  Adequacy  Guidelines."
Moreover,  regulatory  authorities  are  authorized  to prohibit  banks and bank
holding companies from paying dividends if payment of dividends would constitute
an unsafe and unsound banking practice.

     The Federal  Reserve  Board's policy  statement  governing  payment of cash
dividends  provides that we should not pay cash dividends on common stock unless
(i)  our net income for  the past year is  sufficient to fully fund the proposed

<PAGE>107

dividends and (ii) our prospective rate of earnings retention is consistent with
our capital needs, asset quality and overall financial condition.

Community Reinvestment Act

     Under the Community  Reinvestment Act of 1977 and implementing  regulations
of  the  banking  agencies,  a  financial   institution  has  a  continuing  and
affirmative  obligation  (consistent  with safe and sound operation) to meet the
credit  needs  of its  entire  community,  including  low-  and  moderate-income
neighborhoods.  The CRA does not  establish  specific  lending  requirements  or
programs  for  financial  institutions,  nor  does  it  limit  an  institution's
discretion  to develop the types of products and services  that the  institution
believes are best suited to its particular community. The CRA requires that bank
regulatory  agencies  conduct  regular  CRA  examinations  and  provide  written
evaluations  of  institutions'  CRA  performance.  The CRA also requires that an
institution's CRA performance rating be made public.

     The most recent CRA examinations of Humboldt Bank, concluded July 27, 1999,
of Capitol Valley Bank,  concluded  August 10, 2000, of Capitol Thrift and Loan,
concluded October 14, 1998, each resulted in a satisfactory rating. Although CRA
examinations  occur on a regular basis,  CRA  performance  evaluations  are used
principally  in  the  evaluation  of  regulatory  applications  submitted  by an
institution.   CRA   performance   evaluations   are  considered  in  evaluating
applications  for such things as mergers,  acquisitions and applications to open
branches.

     The  Financial  Services  Modernization  Act of  1999  revises  the  CRA by
reducing the frequency of examinations  for smaller banks,  those with assets of
less than $250 million,  and by requiring  disclosure by community  groups as to
the amount of funds received from lenders and the manner those community  groups
used those funds.  These revisions are not expected to significantly  impact the
application of CRA to Humboldt Bancorp.

State Regulation

     As  California-chartered  institutions,  Humboldt Bank, Capitol Valley Bank
and Capitol Thrift and Loan are subject to regular examination by the California
Department  of Financial  Institutions.  State  regulation  affects the internal
organization of Humboldt Bank,  Capitol Valley Bank and Capitol Thrift and Loan,
as well as their savings and thrift deposits,  mortgage lending,  investment and
other activities.  State regulation may contain  limitations on an institution's
activities that are in addition to limitations  imposed under federal law. State
regulation  also contains many  provisions that are consistent with federal law,
such as provisions of California  law limiting  loans by either of Humboldt Bank
or Capitol  Valley Bank to any one borrower to 15.0% of  unimpaired  capital and
surplus,  plus 10.0% of unimpaired  capital and surplus if the additional amount
is fully  secured  by  certain  forms of  "readily  marketable  collateral"  and
limiting  loans at Capitol  Thrift  and Loan to 20% of  unimproved  capital  and
surplus.

     The   California   Department  of  Financial   Institutions   may  initiate
supervisory  measures or formal enforcement actions, and if the grounds provided
by law exist,  the California  Department of Financial  Institutions may place a
California-chartered  financial  institution in conservatorship or receivership.
Whenever the  Commissioner of Financial  Institutions  considers it necessary or
appropriate,  he may also  examine  the  affairs of any  holding  company or any
affiliate of a California-chartered financial institution.

     California Industrial Loan Law

     Capitol  Thrift and Loan is an industrial  loan company  licensed under the
California  Industrial  Loan Law and is regulated,  supervised and  periodically
examined by the California  Department of Financial  Institutions (CDFI) and the
FDIC.

     Industrial loan companies may issue investment certificates and securities,
subject to certain qualifications and approvals.  The total amount of investment
certificates issued and outstanding at any time by an industrial loan company is
subject  to  limitations  based on the  amount  of its  unimpaired  capital  and

<PAGE>108


surplus.  Real estate holdings are limited to the purchase and construction of a
building to carry on business,  property  taken to satisfy a debt,  and property
acquired through foreclosure. An industrial loan company may invest funds in any
investments that are permissible for commercial banks.

     California law authorizes  industrial loan companies to make closed-end and
open-end loans,  with limits or restrictions on aggregate loans to one borrower,
loan-to-value   ratios,   maximum  loan  charges  and  loan  terms,  loan  fees,
advertising, foreclosure procedures and other loan features. California law also
authorizes  insurance premium finance  agencies,  and sets forth regulations for
insurance premium finance loans.

     On  September  30,  2000,  California  adopted  a new law that  transformed
deposit  taking   industrial  loan  companies  into  industrial   banks,  a  new
classification of banks.  Industrial banks now are regulated as banks subject to
California  banking law, and are no longer  subject to any of the laws governing
industrial loans companies;  however, industrial banks are still prohibited from
accepting demand deposits.

Recent Legislation

     Financial  Services  Modernization  Legislation.   On  November  12,  1999,
President  Clinton  signed  into law the  Gramm-Leach-Bliley  Act of 1999,  also
referred to as Financial  Services  Modernization  Act. The  Financial  Services
Modernization Act repeals the two affiliation  provisions of the  Glass-Steagall
Act:  Section 20, which  restricted the  affiliation  of Federal  Reserve member
banks with firms "engaged principally" in specified securities  activities;  and
Section 32, which restricts officer,  director or employee  interlocks between a
member  bank  and  any  company  or  person  "primarily  engaged"  in  specified
securities  activities.  In addition,  the Financial Services  Modernization Act
also contains  provisions  that expressly  preempt any state law restricting the
establishment of financial  affiliations,  primarily  related to insurance.  The
general  effect of the law is to establish a  comprehensive  framework to permit
affiliations among commercial banks, insurance companies,  securities firms, and
other  financial  services  providers  by  revising  and  expanding  the BHC Act
framework  to permit a  holding  company  system  to  engage in a full  range of
financial  activities through a new entity known as a Financial Holding Company.
"Financial activities" is broadly defined to include not only banking, insurance
and securities  activities,  but also merchant banking and additional activities
that the Federal  Reserve  Board,  in  consultation  with the  Secretary  of the
Treasury,  determines to be financial in nature,  incidental  to such  financial
activities or  complementary  activities that do not pose a substantial  risk to
the safety and soundness of  depository  institutions  or the  financial  system
generally. Generally, the Financial Services Modernization Act:

     o    Repeals  historical  restrictions  on, and eliminates many federal and
          state law barriers to,  affiliations  among banks,  securities  firms,
          insurance companies, and other financial services providers;

     o    Provides a uniform  framework  for the  functional  regulation  of the
          activities of banks, savings institutions and their holding companies;

     o    Broadens  the  activities  that may be  conducted  by national  banks,
          banking  subsidiaries  of bank holding  companies and their  financial
          subsidiaries;

     o    Provides an enhanced  framework for protecting the privacy of consumer
          information;

     o    Adopts  a  number  of  provisions   related  to  the   capitalization,
          membership,  corporate  governance,  and other  measures  designed  to
          modernize the Federal Home Loan Bank system;

     o    Modifies  the  laws  governing  the  implementation  of the  Community
          Reinvestment Act, sometimes referred to as CRA; and

<PAGE>109

     o    Addresses a variety of other  legal and  regulatory  issues  affecting
          both  day-to-day  operations  and  long-term  activities  of financial
          institutions.

     In order for a company to take  advantage of the ability to affiliate  with
other financial services providers, it must become a "Financial Holding Company"
as permitted  under an  amendment to the BHC Act. To become a Financial  Holding
Company,  a company would file a  declaration  with the Federal  Reserve  Board,
electing to engage in activities permissible for Financial Holding Companies and
certifying  that the  company is  eligible  to do so because  all of its insured
depository  institution  subsidiaries are well-capitalized and well-managed.  In
addition,  the Federal  Reserve Board must also determine that each of a holding
company's   insured   depository   institution   subsidiaries  has  at  least  a
"satisfactory" CRA rating.

                         MANAGEMENT OF HUMBOLDT BANCORP

     The board of directors of Humboldt  Bancorp  consists of 12 directors.  Not
all of the directors of Humboldt Bancorp then in office immediately prior to the
completion  of the  merger  will  continue  to serve as  directors  of  Humboldt
Bancorp.  Assuming  consummation of the merger,  there will be a total of eleven
directors  including  four  directors  selected by Tehama  Bancorp,  and Messrs.
Mason, Angell,  Evans,  Francesconi,  Janssen,  Winzler and Weborg from Humboldt
Bancorp's existing board.

Board of Directors

     Subject to the terms of the merger agreement, each of the current directors
has been elected to serve for the ensuing year and until his or her successor is
elected and qualified at the annual stockholder  meeting of Humboldt Bancorp for
the year  2001.  As of June 30,  2000,  the  directors,  their  ages,  and their

Compensation of Directors

     Directors of Humboldt Bancorp who are also employees of Humboldt Bancorp or
its  subsidiaries  do not  receive  compensation  for their  service on Humboldt
Bancorp's  board of directors.  During 1998, for the period January through May,
non-employee  directors  of  Humboldt  Bancorp  received a fee of $400 per board
meeting attended and $200 per board meeting not attended; Loan Committee members
received $150 per meeting  attended;  and all other committee  members  received
$100 per meeting attended.  Since June 1998,  non-employee directors of Humboldt
Bancorp have received a fee of $700 per board meeting  attended,  $200 per board
meeting not  attended,  $450 per special board  meeting  attended,  and $200 per
meeting for all committee meetings attended.

     After the merger,  the  directors of Humboldt  Bancorp will receive fees in
amounts  which  are  substantially  similar  to  those  presently  paid  to  the
directors.

Limitation of Liability and Indemnification

     The Articles of  Incorporation  and Bylaws of Humboldt  Bancorp provide for
indemnification of agents including  directors,  officers and employees,  to the
maximum  extent  allowed by  California  law,  including the use of an indemnity
agreement.  The  Articles  further  provide  for  the  elimination  of  director
liability for monetary  damages to the maximum extent allowed by California law.
The   indemnification   law  of  the  state  of  California   generally   allows
indemnification,  in matters not involving the right of the  corporation,  to an
agent of the corporation if that person acted in good faith and in a manner that
person  reasonably believed to be in the best interests of the corporation,  and

<PAGE>111

in the case of a criminal matter, had no reasonable cause to believe the conduct
of that person was unlawful.  California law, with respect to matters  involving
the  right  of  a  corporation,  allows  indemnification  of  an  agent  of  the
corporation,  if the agent acted in good faith, in a manner that person believed
to be in the best interests of the  corporation and its  shareholders;  provided
that there will be no indemnification for:

     o    amounts  paid in settling or otherwise  disposing of a pending  action
          without court approval;

     o    expenses  incurred in  defending a pending  action which is settled or
          otherwise disposed of without court approval;

     o    matters  in which the  agent  will be  determined  to be liable to the
          corporation  unless and only to the extent that the court in which the
          proceeding is or was pending will determine that the agent is entitled
          to be indemnified; or

     o    other matters specified in the California General Corporation Law.

     Humboldt  Bancorp's Articles and Bylaws provide that Humboldt Bancorp will,
to the  maximum  extent  permitted  by law,  have  the  power to  indemnify  its
directors,  officers and employees.  Humboldt Bancorp's Bylaws also provide that
Humboldt Bancorp will have the power to purchase and maintain insurance covering
its directors, officers and employees against any liability asserted against any
of them and incurred by any of them,  whether or not Humboldt Bancorp would have
the power to  indemnify  them for those  liabilities  under  the  provisions  of
applicable law or the provisions of Humboldt Bancorp's Bylaws.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors,  officers or persons controlling Humboldt
Bancorp,  Humboldt  Bancorp  has been  informed  that in the opinion of the SEC,
indemnification  is against public policy as expressed in the Securities Act and
is therefore unenforceable.

     Employment Contracts

     Humboldt Bank entered into an employment agreement with Mr. Mason on May 1,

effective  July 15, 1999,  and has been  extended to January 1, 2002.  Under the
terms of the  agreement,  Mr.  Mason is  entitled  to  receive a base  salary of
$125,000 per year and an incentive  bonus based on a percentage  ranging from 4%
to 2.5% of Humboldt  Bancorp's  pre-tax net profits as provided by an  Incentive
Bonus Plan.  During his term of  employment,  Mr.  Mason may be  reimbursed  for
travel, meals, entertainment expenses, service to charitable organizations,  and
membership in selected committees and other  organizations.  In addition,  he is
eligible for typical  employee  benefits  including paid  vacation,  sick leave,
medical insurance, and the use of an automobile owned by Humboldt Bank.

     Humboldt Bank entered into an employment agreement with Mr. Smyth on August
19,  1989,  whereby Mr.  Smyth  agreed to serve as Humboldt  Bank's  Senior Vice
President and Chief Financial Officer.  Mr. Smyth's employment agreement was for
an initial  three  years to be  automatically  renewed for  successive  one-year
terms. Mr. Smyth's current annual salary is $85,000 per annum. In addition,  Mr.
Smyth is entitled to a percentage of Humboldt  Bank's  pre-tax  profits  ranging
from 2% to .5%.

Mr.  Barkley's  current  annual  salary is $85,000 per annum.  In addition,  Mr.
Barkley is  entitled  to a  percentage  of Humboldt  Bancorp's  pre-tax  profits
ranging from 2% to .5%.

Benefit Plans

     Retirement  Plan:  Humboldt Bancorp has a defined  contribution  retirement
plan,  for which  Humboldt  Bank and Capitol  Valley Bank signed on as sponsors,
covering  substantially  all of Humboldt  Bancorp  and its banking  subsidiaries
employees.  Management  is in the  process  of  adopting  the plan as a Humboldt
Bancorp Plan. Bank  contributions  to the plan are made at the discretion of the
boards of directors of the subsidiary banks in amounts not to exceed the maximum
amounts  deductible  under the profit sharing plan rules of the Internal Revenue
Service. Employees may elect to have a portion of their compensation contributed
to the plan in  conformity  with  the  requirements  of  Section  401(k)  of the
Internal  Revenue Code.  Bank  contributions  to the plans were $223,000  during
1999, $188,000 during 1998, and $134,000 during 1997.

     Director Fee Plan:  Humboldt Bancorp has adopted the Humboldt Bank Director
Fee Plan (the "Fee  Plan").  The Fee Plan  permits  each  director  of  Humboldt
Bancorp  to elect to receive  his/her  director's  fees in the form of  Humboldt
Bancorp common stock,  cash, or a combination  of Humboldt  Bancorp common stock
and cash,  and to elect to defer the receipt of any of the  foregoing  until the
end of his/her term as a Bank  director.  If deferral is elected,  the amount of
the  director's  fees will be credited to an account on behalf of the  director.
However,  this crediting will  constitute a mere promise on the part of Humboldt
Bank and Humboldt  Bancorp to  pay/distribute  on this  account.  The account is
otherwise unsecured and unfunded, and subject to the general claims of creditors
of Humboldt Bank and Humboldt Bancorp. The Fee Plan provides for the issuance of
up to 40,000 shares of Humboldt  Bancorp  common  stock.  The amount of director
fees deferred in 1999 was $85,000, in 1998 was $57,000, and in 1997 was $43,000.
At December  31, 1998 and 1999,  the  liability  for amounts due under this plan
totaled  $108,000 and  $194,000,  or  approximately  4,758 and 18,940  shares of
stock, respectively.

     Employee Stock Bonus Plan:  Humboldt Bank has an Employee Stock Bonus Plan,
which is funded annually at the sole  discretion of the board of directors.  The
plan is  currently  sponsored  by  Humboldt  Bank only.  Funds are  invested  in
Humboldt Bancorp common stock, when available, which is purchased at the current
market  price on  behalf of all  employees  except  the  executive  officers  of
Humboldt Bancorp.  The compensation cost recognized for 1999, 1998, and 1997 was
$20,000 each year.  In addition,  in 1999,  $100,000  was  transferred  from the
profit sharing plan discussed above under "Benefit Plans -- Retirement Plan."

     Post-Employment Benefit Plans and Life Insurance Policies: Humboldt Bancorp
has  entered  into  Officer   Salary   Continuation   Agreements   and  Deferred
Compensation  Agreements  with key executive  officers and certain  employees of
Humboldt  Bancorp,  Humboldt  Bank and  Capitol  Valley  Bank.  The  Officer and
Employee  Salary  Continuation  Agreements  provide for payments in the event of
retirement,  death,  disability or change in control. The Deferred  Compensation
Agreements  allow the  employees to defer a portion of current  compensation  in
exchange  for  Humboldt  Bancorp's  commitment  to  pay a  deferred  benefit  at
retirement. Deferred compensation is vested as to the amounts deferred. If death
occurs prior to or during  retirement,  Humboldt Bancorp will pay the employee's
beneficiary or estate the benefits set forth in the agreement.  Both the Officer
Salary  Continuation  Agreements  and the Deferred  Compensation  Agreements are
unfunded  although,  as discussed  below,  Humboldt  Bancorp has purchased  life
insurance policies in connection with their implementation.

     The Officer Salary Continuation Agreements provide that upon retirement, or
death prior to retirement,  the following executive officers will be entitled to
the following benefits: Theodore S. Mason - $100,000 per year for 15 years; Alan
J. Smyth - $40,000 per year for 10 years;  Ronald V.  Barkley - $40,000 per year
for 10 years;  Paul A.  Ziegler - $142,000  for 15 years;  Kenneth J.  Musante -
$78,542 per year for 15 years; John E. Dalby -$128,165 per year for 15 years and
Richard L. Whitsell - $74,102 per year for 15 years. In the event of disability,
these employees will be entitled to the following  amounts payable over the same
period unless  otherwise  noted:  Theodore S. Mason - $472,202,  Alan J. Smyth -
$252,237,  Ronald V. Barkley - $252,237,  Paul A. Ziegler - $40,694,  Kenneth J.
Musante - $146,665,  John E. Dalby - $39,151, and Richard L. Whitsell - $123,724

<PAGE>114

in a lump sum or as otherwise agreed.  Salary continuation  benefits may also be
paid if  termination  is without cause or due to a change in control of Humboldt
Bancorp.

     In the event of a change of  control,  the  officers  named  below  will be
entitled to full vesting of their benefits under the Officer Salary Continuation
Agreements, and if an executive officer in connection with the change of control
is terminated  without cause, he shall be entitled to the fully vested payments.
The fully vested payments are as follows:  Theodore S. Mason - $472,202, Alan J.
Smyth -  $252,237,  Ronald V.  Barkley -  $252,237,  Paul A.  Ziegler - $40,694,
Kenneth J. Musante - $158,398, John E. Dalby - $39,151 and Richard L. Whitsell -
$123,724.

     Humboldt  Bancorp has purchased  single premium life insurance  policies in
connection with the  implementation  of these salary  continuation  and deferred
compensation   plans.  The  policies  provide  protection  against  the  adverse
financial  effects  from  their  death and  provide  income  to offset  expenses
associated  with the  plans.  The  specified  employees  are  insured  under the
policies,  but Humboldt Bancorp is the owner and  beneficiary.  At June 30, 2000
and  December  31, 1999 and 1998,  the cash  surrender  value of these  policies
totaled approximately $8,461,000, $5,157,000 and $4,943,000, respectively.

     At June 30, 2000 and December 31, 1999 and 1998,  liabilities  recorded for
the  estimated  present  value  of  future  salary   continuation  and  deferred
compensation   benefits  totaled   approximately   $2,970,000,   $2,716,000  and
$2,038,000,  respectively.  In the  event  of  death  or  under  other  selected
circumstances,  Humboldt Bancorp is contingently  liable to make future payments
greater   than  the   amounts   recorded  as   liabilities.   Based  on  present
circumstances,  Humboldt  Bancorp  does  not  consider  it  probable  that  this
contingent liability will be incurred or that in the event of death, a liability
would be material after consideration of life insurance benefits.

     Stock  Option  Plan:  Humboldt  Bancorp has a stock option plan under which
incentive and non-statutory stock options, as defined under the Internal Revenue
Code, may be granted.  Options  representing  456,255 shares of the Bancorp's no
par value common  stock may be granted  under the plan by the board of directors
to directors,  officers and key,  full-time  employees at an exercise  price not
less than the fair market value of the shares on the date of grant. In addition,
at  December  31,  1999  and  June  30,  2000,   671,762  and  612,163  options,
respectively,  were  outstanding that were granted by Humboldt Bank prior to the
formation of the Bancorp. Options may have an exercise period of not longer than
ten years,  and the options are subject to a graded vesting  schedule of 33% per
year for incentive stock options. Non-statutory stock options vest immediately.

     The Stock Option Plan contains an antidilution  provision in the event of a
private or public offering of Humboldt  Bancorp common stock.  Under the current
antidilution  provision,  participants  will be  granted  additional  options to
purchase  shares of Humboldt  Bancorp common stock based on the number of shares
issued in the public offering.  Additional  options will be granted to a current
employee,  officer or director who hold options so as to maintain an  optionee's
proportionate  interest in Humboldt  Bancorp by reason of his or her unexercised
portions of options as before the  issuance.  However,  the total number may not
exceed that available for grant under the Humboldt Bancorp Stock Option Plan and
the former Humboldt Bank Stock Option Plan.  Directors of Humboldt  Bancorp have
agreed to waive the antidilution provision of the stock option plan representing
approximately 42% of the outstanding options under the stock option plans.

     The exercise  price for such  additional  options  shall be the fair market
value of the Humboldt Bancorp common stock on the date of the additional  grant,
except that in the case of an incentive  stock option,  the exercise price shall
be 110% if the  optionee  is an employee  owning  more than 10% of the  combined
voting power of all classes of stock of Humboldt Bancorp.

     The  following  tables set forth the number of options  granted to Humboldt
Bancorp's executive officers during 1999 and the number and value of unexercised
options held by these executive officers as of December 31, 1999.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     During  2000,  we had a $3.8  million  line of credit  extended  to Bancorp
Financial Services,  in which we own a 50% interest.  The line of credit expired
May 2, 2000,  and was not  renewed.  It had borne an interest  rate of the prime
rate published in the Wall Street  Journal plus 0.25% per annum.  During each of
the years ended December 31, 1999 and 1998, the maximum amount outstanding under
the line of credit was $3.0  million.  Further,  during  each of the years ended
December  31, 1999 and 1998,  Humboldt  Bank  purchased  $2.0  million in leases
generated by Bancorp  Financial  Services;  however,  none were  purchased  from
Bancorp Financial Services during the six-month period ending June 30, 2000.

     Some of Humboldt  Bancorp's  directors  and  executive  officers  and their
immediate  families,  as well as the companies in which they may have interests,
have had loans with Humboldt Bank in the ordinary course of the Bank's business.
In  addition,  Humboldt  Bank  expects to have  loans with these  persons in the
future.  In management's  opinion,  all these loans and commitments to lend were
made in the ordinary course of business, were made in compliance with applicable
laws on substantially the same terms,  including  interest rates and collateral,
as those  prevailing for comparable  transactions  with other persons of similar
creditworthiness and, in the opinion of management,  did not involve more than a
normal  risk of  collectibility  or  present  other  unfavorable  features.  The
outstanding balance under extensions of credit by Humboldt Bank to directors and
executive  officers of Humboldt  Bancorp and Humboldt  Bank and to the companies
that these directors and executive officers may have an interest was $4,865,000,
$6,451,000, and $6,218,000 as of December 31, 1999, 1998 and 1997, respectively.

     We have, and in the future will, enter into transactions with our directors
or companies in which they may have an interest.  During the year ended December
31, 1999, 1998 and 1997, no transaction exceeded $60,000, except that we engaged
the services of Dalianes  Worldwide Travel Service,  which was formerly owned by
Marguerite Dalianes, one of our directors. Fees paid by us to Dalianes Worldwide
Travel  Service  for the year ended  December  31,  1999 and 1998,  amounted  to
$77,000 and $73,000, respectively.

                 DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATION

     The following  management's  discussion and analysis of financial condition
and results of operation contains forward-looking  statements that involve risks
and uncertainties.  Tehama Bancorp's actual results could differ materially from
those anticipated in these forward-looking statements as a result of the factors
described in the section entitled "Risk Factors" and elsewhere in this document.

Business Organization

     Tehama Bank,  chartered as Tehama  County Bank in Red Bluff,  California in
1984, was created by local business people with  $2,500,000 in initial  capital.
Tehama  Bancorp,  Tehama Bank's parent holding  company was created in 1997 with
Tehama Bank as its only  subsidiary.  The Red Bluff Branch remains Tehama Bank's
main office and largest of six branch locations. Tehama Bank has branches in Los
Molinos  (Tehama  County),  Chico  (Butte  County),  Willows  and Orland  (Glenn
County),  and Redding (Shasta  County).  Branch support services are provided by
centralized  operations  and loan  centers  located in the Tehama Bank  Business
Center in Red Bluff,  adjacent to Tehama Bank and Tehama Bancorp  administrative
offices.

     Throughout  its  history,  Tehama  Bank has engaged in basic  consumer  and
commercial banking, offering a diverse range of banking products and services to
individuals,  businesses and the professional community.  Tehama Bank's Merchant
Card Processing  Department  processes  third-party credit card transactions for
selected merchants under contract to a third party. In 1996, Tehama Bank entered
into a joint venture  agreement with Humboldt Bank to organize Bancorp Financial
Services.  Bancorp  Financial  Services  makes  consumer  automobile  loans  and
commercial equipment leases of generally less than $100,000 to small businesses.
During  1999,  Tehama Bank  installed a wide area  computer  network to link its
branches and operating  departments,  which provides enhanced  communication and
customer  service.  Tehama  Bank also has a website at  "tehamabank.com",  which
offers extensive product information,  rate charts,  interactive  calculators to
assist  customers  with their savings plans and loan payment  calculations,  and
on-line banking, which enables customers to view their account information,  pay
bills, and transfer funds between accounts.  Late in the fourth quarter of 1998,
Tehama Bank expanded its Manufactured Housing lending activities by establishing
a dedicated department to meet the needs of this segment of its business. At the
same time,  Tehama Bank also  established an ATM Services  department to furnish
cash to automated  teller machines (ATMs) owned by third parties  throughout the
United States.

Overview

     For the six months ended June 30,  2000,  net income was $1.4  million,  an
increase of 56.3% over net income of $.9  million for the six months  ended June
30, 1999. Diluted earnings per share were $.72 and $.47 for the six months ended
June 30,  2000 and June 30,  1999,  respectively.  Annualized  return on average
assets was 1.25% for the six months ended June 30, 2000, compared with 0.89% for
the comparable six months in 1999. For the first six months of 2000,  annualized
return on average  equity was  14.32%,  compared  with  10.23% for the first six
months of 1999. The increase in earnings for the six months ended June 30, 2000,
can be attributed to growth in earning  assets,  increases in service charges on
deposit accounts,  growth in ATM cash servicing  income,  and a reduction in the
provision for loan and lease losses.

     Net  income  for the year  ended  December  31,  1999,  was  $2.2  million,
representing  an increase of $.2  million,  or 10.0%,  over the $2.0 million for
1998,  which was an increase of $.7  million,  or 53.8%,  over the net income of
$1.3 million for the year ended December 31, 1997.  Shareholders' equity totaled
$18.6 million on December 31, 1999, compared to $17.7 million in 1998, and $15.9
million at December 31, 1997. Diluted earnings per share for 1999, 1998 and 1997
were $1.20, $1.06 and $.71, respectively.

<PAGE>119

     For the year 1999, net interest income increased $.7 million (8.5%) to $8.9
million from $8.2  million in 1998.  The interest  income  component  was up $.2
million  (1.4%) to $14.0  million from $13.8  million,  due to an $11.9  million
(7.0%) increase in average  earning assets.  The yield on average earning assets
decreased  by 44 basis  points in 1999,  to 7.70%,  from 8.14% in 1998.  Average
loans increased $9.4 million,  however,  the yield decreased by 69 basis points,
to 8.56% from 9.25%,  resulting in  substantially  the same  interest  income on
loans of $11.2  million  in 1999 and in 1998.  Investment  income on  securities
increased $1.0 million  (66.7%) to $2.5 million from $1.5 million in 1998 due to
an increase in average  securities  of $16.7 million and an increase of 13 basis
points in yield,  to 5.66% in 1999 from  5.53% in 1998.  Average  fed funds sold
decreased by $14.2 million and the yield  decreased by 43 basis points to 4.79%.
Interest expense on deposits decreased by $.5 million (9.8%) to $5.1 million.

     Non-interest income for 1999 increased $.9 million (32.1%) to $3.7 million.
Third-party ATM servicing  fees, a service started at the end of 1998,  provided
$.5 million of the increase.  Loan packaging fees from the manufactured  housing
division  provided  $.3  million  and income  from  Bancorp  Financial  Services
provided $.1 million.  Merchant  processing  fees  decreased $.2 million to $1.1
million.

     Non-interest expense increased $1.2 million in 1999 (16.9%) to $8.3 million
from $7.1 million in 1998.  This increase was  attributed to increases in salary
and related benefits expenses of $.5 million (13.2%),  occupancy expenses of $.1
million  (14.0%),  and all other  non-interest  expenses of $.6 million (24.4%).
These  increases  were the result of opening of a branch in Redding in September
1998,  installation  of a Wide Area Network  connecting  all  branches,  support
departments,  and  administration,  start-up  costs for lending  and  speciality
departments,  relocation  of the Red Bluff branch and loan  center,  and overall
general expansion.

     Assets of Tehama  Bancorp were $211.8  million at December 31, 1999,  which
was an increase of $12.0  million,  or 6.0% from the $199.8  million at year end
1998, which was an increase of $30.1 million,  or 17.7%, over the $169.7 million
at December 31, 1997.  Net loans at year end 1999 were $143.0,  up $24.0 million
(20.2%) from $119.0 at year end 1998,  which was an increase of $.3 million,  or
0.3%,  from $118.7 million at December 31, 1997.  Nonperforming  loans were $1.4
million at the end of 1999  compared  to $.9 million at the end of 1998 and $1.2
million at the end of 1997.  Deposits grew $8.0 million (4.4%) to $188.5 million
at December 31,  1999,  from $180.5  million at December 31, 1998,  which was an
increase of $27.8  million,  or 18.2%,  over the $152.7  million at December 31,
1997.

     For the six months ended June 30, 2000, Tehama Bancorp realized a return on
average  assets of 1.25%,  compared to 1.11% for 1999,  1.10% for 1998 and 0.80%
for 1997.  For the six months ended June 30,  2000,  Tehama  Bancorp  realized a
return on average  shareholders' equity of 14.32%,  compared to 12.52% for 1999,
11.91% for 1998, and 8.39% for 1997.

     Tehama  Bancorp  ended 1999 with a Tier 1 capital  ratio of 12.6%,  a total
risk-based  capital  ratio of 13.9%,  and  leverage  ratio of 9.4%.  For the six
months ended June 30, 2000,  Tehama Bancorp had a Tier 1 capital ratio of 11.7%,
a total risk based capital ratio of 12.9% and a leverage ratio of 9.2%.

Net Interest Income / Net Income

     Net interest  income  represents  the excess of interest and fees earned on
interest-earning  assets  (loans,  securities  and federal  funds sold) over the
interest  paid on  deposits  and  borrowed  funds.  Net  interest  margin is net
interest income expressed as a percentage of average earning assets.

     Net  interest  income for 1999  totaled $8.9 million and was up $.7 million
(8.5%) over the prior year. The interest income  component was up $.2 million to
$14.0  million.  Most of the  increase  was  attributable  to growth in  average
earning assets,  primarily in commercial loans,  which increased $9.4 million in
1999 over 1998.  Average  outstanding  loan balances of $130.6  million for 1999
reflected a 7.8%  increase over 1998  balances.  This  increase  contributed  an
additional  $.9  million to  interest  income.  This  increase  was offset by an

<PAGE>120

average 69 basis point  decrease  in loan yields that caused a reduction  of $.9
million in interest income.  Competitive pressures on loan pricing and increases
in the  outstanding  volume of indirect auto loans have generally  lower yields.
Average  balances on the investment  portfolio grew $16.7 million  (62.1%) which
added $.9 million to interest  income.  The average yield received on securities
was up 13 basis points and added $.1 million to interest income. Interest income
on Federal funds sold  decreased $.7 million as the average  balances were $14.2
million (64.5%) lower.

     Interest  expense  decreased  $.5  million  (8.9%) in 1999 over  1998.  The
average balances of interest bearing liabilities increased $10.9 million (8.5%).
The  higher  balances  were due  largely  to growth in  interest-bearing  demand
deposit  accounts.  Interest  expense  attributable to the higher volume was $.3
million.  Lower rates paid on all interest bearing liabilities and the increased
proportion of lower rate demand  deposits more than offset the higher expense by
$.8 million.  Net interest  margin for 1999 was 4.89% versus 4.84% in 1998.  Net
interest income for 1999 totaled $8.9 million and was up 8.5% ($.7 million) over
1997.

     Average earning assets were $170.1 million in 1998 for an increase of $18.1
million over 1997. In 1998,  interest income  increased by $1.3 million to $13.9
million. The average yield received on all interest earning assets fell 16 basis
points to 8.14%.  Interest  expense  increased  $.4 million  (7.7%) in 1998 over
1997. Average interest bearing liabilities  increased $12.2 million in 1998. Net
interest margin for 1998 and 1997 was 4.84% and 4.86%, respectively.

     The first of the following two tables presents,  for the periods indicated,
Tehama Bancorp's  interest income from average earning assets,  interest expense
on average  interest-bearing  liabilities,  and Tehama  Bancorp's  net  interest
income and net  interest  margins.  The second  table  presents a summary of the
effect of the changes in volumes and rates for each major  component  of earning
assets and  interest-bearing  liabilities and their contribution to net interest
income. It shows the portion attributable to changes in average rates versus the
portion  attributable to changes in average  volumes for the periods  indicated.
Changes in interest  income and expense  resulting from combined rate and volume
changes have been allocated to volume changes.

Non-interest Income and Expense

     Non-interest Income

     Tehama  Bancorp   receives  a  significant   portion  of  its  income  from
non-interest  sources related both to activities  conducted by Tehama Bank (loan
originations, servicing and depositor service charges), as well as from Merchant
Bankcard   processing  fees,  ATM  servicing  fees,   income  from  the  leasing
subsidiary,  and loan packaging  fees.  The following  table presents the dollar
amount of Tehama Bancorp's  non-interest income for the years ended December 31,
1997, 1998 and 1999, respectively.

</TABLE>


     Non-interest income increased  $220,000,  or 13.1% for the six month period
ended June 30,  2000,  compared  to the six  months  ended  June 30,  1999.  The
increase  was  primarily  the  result of  increased  service  charges on deposit
accounts and growth in revenues from the ATM cash servicing department.

     Non-interest  income  increased  $939,000 or 33.5% in 1999 to $3.7 million.
The  increase  was  primarily  the result of an  increase  of $452,000 in income
resulting  from Tehama  Bank's entry into the business of servicing  third party
ATM machines and $261,000 in loan packaging fees on manufactured  housing loans.
Additional  non-interest  income  categories  reflecting  an  increase  in  1999
included:  depositor service charges, up $66,000 primarily as a result of growth

<PAGE>123

in Tehama Bancorp's deposit base; income from Tehama Bancorp's 50% investment in
Bancorp  Financial  Services,  up  $143,000 as a result of  increased  volume of
leasing activity;  and gains on the sale of real estate  mortgages,  up $74,000.
All other non-interest income decreased by $56,000 from 1998.

     Non-interest  income  categories with decreased  income in 1999 were led by
gain on sale of loans with a decline of  $252,000  and a decrease of $263,000 in
income  generated  by the Merchant  Bankcard  department.  In 1991,  Tehama Bank
contracted with  CardService  International,  Inc. (CSI) for the solicitation on
behalf of Tehama Bank of merchants  who accept credit cards as payment for goods
and services. As a result, Tehama Bank has obtained electronic credit card draft
processing  relationships  with  approximately  27,000 merchants on a nationwide
basis.  Tehama Bank also entered into an  agreement  with First Data  Resources,
Inc. (FDRI) for the processing of merchant credit card transactions.  Because of
increased  competition for this business among community banks,  Tehama Bank and
CSI  renegotiated  their contract in March of 1999 for an additional five years.
Among other things,  the contract  provided for a declining  level of fee income
over the life of the contract,  a provision  whereby the Bank reimburses CSI for
50% of the  earnings  on all  funds  held  by  Tehama  Bank  for  CSI,  and  the
elimination of  reimbursement  by CSI of personnel costs incurred by the bank in
providing  merchant  card  services  to CSI.  Fee income to Tehama Bank from CSI
totaled $.4 million for the six months ended June 30, 2000, $1.1 million for the
twelve months ended December 31, 1999,  $1.3 million for the twelve months ended
December 31, 1998,  and $1.3  million for the twelve  months ended  December 31,
1997.  Fee income  under the  revised  contract  is  expected  to decline to $.9
million in 2000, $.7 million in 2001, and $.6 million in 2002, and 2003.

     For the  year  ended  December  31,  1998,  non-interest  income  increased
$610,000  or 27.8% to $2.8  million  from  $2.2  million  in 1997.  The  overall
increase in  non-interest  income was primarily  the result of increased  income
from  Bancorp  Financial  Services,  up  $266,000,  service  charges  on deposit
accounts, up $163,000, and gains on sale of loans up $59,000.

     Non-interest Expense

     Non-interest  expense  reflects the costs of products,  services,  systems,
facilities and personnel for Tehama Bancorp.  Non-interest expense increased $.2
million,  or 6.1%,  to $4.2  million  for the six months  ended  June 30,  2000,
compared to $4.0 million in the corresponding period of 1999.

     The following table presents Tehama Bancorp's  non-interest expense for the
six months ended June 30, 1999 and 2000,  and the years ended December 31, 1997,
1998 and 1999, respectively.

     Salaries and Related Benefits

     Salary and related benefits expense remained essentially  unchanged at $2.1
million for the six month periods ended June 30, 2000 and June 30, 1999. At June
30, 2000,  the full time  equivalent  (FTE) staff was 107 versus 116 at December
31, 1999.

     Salary and related  benefits  expense  increased  $500,000  (13.2%) to $4.3
million in 1999 from $3.8 million in 1998. At the end of 1999, the FTE staff was
116  versus  105 at the end of 1998.  Salaries  and  employee  related  benefits
expense for 1998 was $3.8  million,  an increase of 35.5% over the $2.8  million
incurred  in  1997.  Increases  in  salary  expense  during  these  periods  are
attributable to the hiring of additional branch, administrative,  unique lending
and other specialty  department personnel due to the significant growth recorded
by Tehama Bank during those years. In 1998, the FTE staff increased 14 positions
from the end of  1997.  Statement  of  Financial  Accounting  Standards  No.  91
requires  Tehama  Bank to defer  loan  origination  costs  (salary  and  related
benefits)  associated with the origination of loans,  which results in recording
salary  expense at an amount less than that  actually  paid by Tehama Bank.  The
capitalized  costs amounted to $603,000 in 1999,  $154,000 in 1998, and $259,000
in 1997.

     Occupancy and Furniture and Equipment

     Premise and fixed asset related  occupancy  expenses,  including  equipment
expenses,  were  $581,000 for the six months  ended June 30,  2000,  compared to
$487,000 for the  equivalent  period in 1999, an increase of 19.3%.  Premise and
fixed asset related occupancy expenses,  including equipment expenses, were $1.1
million in 1999.  This was an increase of $132,000  (14.0%) over 1998. For 1998,
occupancy expenses increased $114,000 or 13.7% to $946,000 over 1997.  Increases
during  these  periods are  attributable  to the opening of a branch in Redding,
California,  installation of a Wide Area Network, start-up costs associated with
unique lending and other  specialty  departments and relocation of the Red Bluff
branch and loan center.

     Other Expenses

     All other  non-interest  expenses  increased  $169,000,  or 12.3%,  to $1.5
million for the six months ended June 30, 2000,  compared to $1.4 million in the
corresponding  period of 1999.  The  increase  was  primarily  due to  increased
advertising expenses,  other professional services and costs associated with the
merchant card services operation.

     All other non-interest  expenses increased $600,000 (24.4%) to $2.9 million
in 1999 from $2.3 million in 1998. Increases in all other non-interest  expenses
primarily  consisted of increases in professional  services  expenses of $63,000
(26.6%),  primarily  due to  additional  legal  expenses  related to  collection
efforts in certain credit relationships,  implementation of a stock option plan,
and  implementation  of a  shareholder  rights  plan.  In  addition,  there were
increases in stationery and supplies  expenses of $60,000 (42.0%),  increases in
telephone  expenses  of $69,000  (56.6%),  increases  in all other  expenses  of
$375,000  (20.6%),  all of which increased  primarily due to the addition of the
Redding  branch,  start-up  costs  associated  with unique lending and specialty
departments,  relocation  of the Red Bluff branch and loan  center,  and overall
general expansion during 1999. All other  non-interest  expenses were relatively
unchanged in 1998  compared to 1997,  decreasing  only $7,000 (0.3%) during that
period.

Provision for Taxes

     The  effective  tax rate on income was 28.7% for the six months  ended June
30, 2000, compared to 27.3% for the comparable period in 1999. The effective tax
rate on income was 26.5%, 29.8%, and 32.0% in 1999, 1998 and 1997, respectively.
The primary factor reducing the effective tax rate of Tehama Bancorp in 1999 was
due to  permanent  differences  in tax  accounting  from  obligations  of  state
political  subdivisions  and for income  from  Tehama  Bancorp's  investment  in
Bancorp Financial Services.

Balance Sheet Analysis

Loans and Leases

     Tehama Bank  concentrates  its lending  activities in four principal areas:
installment  loans (including  indirect auto loans);  real estate mortgage loans
(including  construction);  commercial  real estate loans and  commercial  loans
(including  agricultural  loans).  At  June  30,  2000,  these  four  categories
accounted  for  approximately  31%,  26%,  20%,  and 20% of Tehama  Bank's  loan
portfolio,   respectively.   At  December  31,  1999,   these   categories  were
approximately   30%,  31%,  16%,  and  19%  of  Tehama  Bank's  loan  portfolio,
respectively,  as compared to 26%, 39%,  10%, and 19% at December 31, 1998.  The
increase in commercial  real estate loans  reflects  Tehama  Bank's  emphasis on
commercial  and  business-related  loans,  while  growth  in  installment  loans
occurred as a result of continued  growth in the indirect  auto loan  portfolio.
The following  table  summarizes the composition of the loan and lease portfolio
as of December 31, 1995, 1996, 1997, 1998, and 1999, and June 30, 2000.

     The majority of Tehama  Bank's loans are direct loans made to  individuals,
local  businesses  and  agri-businesses.  Direct loans are originated at each of
Tehama Bank's branch  offices and by various loan  specialists  who cover Tehama
Bank's  entire  service  area.  Tehama  Bank  also  purchases  installment  loan
contracts  for the  purchase of new and used  automobiles  from area  automobile
dealers and originates loans for the purchase of manufactured  homes for sale to
third parties.  Tehama Bank relies substantially on local promotional  activity,
and personal contacts by bank officers,  directors and employees to compete with
other  financial  institutions.  Tehama  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.  Commercial  loans  are  diversified  as to  industries  and types of
business, with no material industry or specific borrower  concentrations.  These
loans are generally  made to small and mid-size  businesses  and  professionals.
Commercial  loans  consist  of  credit  lines  for  operating  needs,  loans for
equipment purchases,  working capital, and various other business loan products.
Most of these loans have floating  rates with the majority tied to Tehama Bank's
reference  rate,  which is set based on the  prime  rate  established  by Tehama
Bank's  primary  correspondent  bank.  The primary  source of  repayment on most
commercial  loans is cash flow from primary business  operations.  Collateral in
the  form  of  real  estate,  cash  deposits,  accounts  receivable,  inventory,
equipment or other financial instruments is often obtained as a secondary source
of repayment.  Leases are secured by equipment  and,  while sold to Tehama Bank,
are  serviced  by  Tehama  Bancorp's  jointly  owned  leasing  company,  Bancorp
Financial  Services.  Interest  recorded on these  leases is reflected in Tehama
Bank's interest income category.

     Installment  loans  include a range of  traditional  consumer loan products
offered by Tehama  Bancorp such as personal lines of credit and loans to finance
purchases of autos, boats, recreational vehicles, mobile homes and various other
consumer items. The construction  loans are generally composed of commitments to
customers  within  Tehama  Bancorp's  service  area  for  construction  of  both
commercial  properties  and  single-family  residences.  Other real estate loans
consist  primarily of loans to Tehama Bank's  depositors  secured by first trust
deeds  on  commercial  and  residential  properties  typically  with  short-term
maturities and original loan to value ratios not exceeding 75%. Average loans in
1999 were $130.6 million  representing  an increase of $9.4 million or 7.7% over
1998.  Average loans of $121.2 million in 1998  represented an increase of $12.1
million or 11.1% from $109.1 million in 1997.

Risk Elements

     Tehama Bancorp assesses and manages credit risk on an ongoing basis through
stringent credit review and approval policies, extensive internal monitoring and
established formal lending policies. Additionally, Tehama Bancorp contracts with
an outside loan review consultant to periodically  grade new loans and to review
the existing  loan  portfolio.  Management  believes its ability to identify and
assess risk and return  characteristics  of Tehama  Bancorp's  loan portfolio is
critical for profitability and growth.  Management  emphasizes credit quality in
the loan approval process,  active credit administration and regular monitoring.
With this in mind,  management has designed and implemented a comprehensive loan
review and grading system that  functions to continually  assess the credit risk
inherent in the loan portfolio.  Ultimately, credit quality may be influenced by
underlying trends in the economic and business cycles.

     Tehama  Bancorp's  business is  concentrated in Tehama,  Shasta,  Glenn and
Butte  counties  in  California   whose  economy  is  highly  dependent  on  the
agricultural,  timber and tourism industries.  As a result, Tehama Bancorp lends
money to individuals and companies dependent upon these industries.

     Tehama  Bancorp  monitors  the  effects of current  and  expected  economic
conditions  and  other  factors  on  the   collectibility  of  loans.  When,  in
management's  judgment,  these loans are impaired,  an appropriate provision for
losses is recorded.  In extending  credit and  commitments to borrowers,  Tehama
Bancorp  generally  requires  collateral  and/or  guarantees  as  security.  The
repayment of such loans is expected to come from cash flow or from proceeds from
the sale of selected assets of the borrowers.  Tehama Bancorp's  requirement for
collateral and/or guarantees is determined on a case-by-case basis in connection
with  management's   evaluation  of  the   credit-worthiness  of  the  borrower.
Collateral held varies but may include accounts receivable, inventory, property,
plant and  equipment,  income-producing  properties,  residences  and other real
property.  Tehama  Bancorp  secures its collateral by perfecting its interest in
business or personal  assets,  obtaining deeds of trust, or outright  possession
among other means.

     Management  believes that its lending policies and  underwriting  standards
will tend to  minimize  losses in an  economic  downturn,  however,  there is no
assurance that  losses will not  occur under such circumstances.  Tehama  Bank's

<PAGE>128

loan policies and underwriting  standards  include,  but are not limited to, the
following: 1) maintaining a thorough understanding of Tehama Bank's service area
and  limiting  investments  outside  of this  area,  2)  maintaining  a thorough
understanding of borrowers'  knowledge and capacity in their field of expertise,
3) basing real estate  construction  loan approval not only on salability of the
project,  but also on the borrowers' capacity to support the project financially
in the event it does not sell within the original  projected time period, and 4)
maintaining  conforming  and prudent loan to value and loan to cost ratios based
on independent  outside appraisals and ongoing inspection and analysis by Tehama
Bank's lending officers. In addition,  Tehama Bank strives to diversify the risk
inherent in the portfolio by avoiding concentrations to individual borrowers and
on any one project.

Nonaccrual, Past Due and Restructured Loans

     Tehama Bancorp's  current policy is to cease accruing  interest when a loan
becomes  90-days past due as to principal  or  interest;  when the full,  timely
collection of interest or principal becomes uncertain;  or when a portion of the
principal  balance has been charged off,  unless the loan is well secured and in
the  process of  collection.  When a loan is placed on  nonaccrual  status,  the
accrued  and  uncollected  interest  receivable  is  reversed  and  the  loan is
accounted for on the cash or cost recovery method  thereafter,  until qualifying
for return to  accrual  status.  Generally,  a loan may be  returned  to accrual
status when all delinquent  interest and principal  become current in accordance
with the terms of the loan  agreement  or when the loan is both well secured and
in process of collection.  The following table sets forth  nonaccrual  loans and
loans past due 90 days or more as of December 31,  1995,  1996,  1997,  1998 and
1999, and as of June 30, 2000, respectively:

     At June 30, 2000,  the  recorded  investment  in loans that are  considered
impaired  was  $213,000.  Such  impaired  loans  had a  valuation  allowance  of
$106,000.  At December  31,  1999,  the  recorded  investment  in loans that are
considered impaired was $259,000.  Such impaired loans had a valuation allowance
of $78,000.  The recorded investment in impaired loans at December 31, 1998, was
$1.4 million and the related allowance for loan and lease losses for these loans
was $459,000.  Tehama  Bancorp  recognized no interest  income on impaired loans
during  these  periods.  There  were no  troubled  debt  restructurings  or loan
concentrations  in excess of 10% of total  loans not  otherwise  disclosed  as a
category  of loans as of  December  31,  1999.  Management  is not  aware of any
potential  problem loans,  which were accruing and current at December 31, 1999,
where  serious doubt exists as to the ability of the borrower to comply with the
present repayment terms.

Other Real Estate Owned

     Other real estate owned was $168,000, $36,000, $50,000 and $339,000 at June
30, 2000, and December 31, 1999, 1998 and 1997, respectively.

Allowance for Loan and Lease Loss Activity

     The  provision  for loan  and  lease  losses  is  based  upon  management's
evaluation  of the  adequacy  of the  existing  allowance  for loans and  leases
outstanding.  The  allowance is increased by  provisions  charged to expense and
reduced  by  loan  charge-offs  net  of  recoveries.  Management  determines  an
appropriate  provision based upon the interaction of three primary factors:  (1)
the loan and lease portfolio growth in the period,  (2) a comprehensive  grading
and  review  formula  for total  loans and  leases  outstanding,  and (3) actual
previous  charge-offs.  The  allowance  for loan and lease  losses  totaled $2.4
million or 1.48% of total  loans and leases at June 30,  2000,  compared to $2.1
million or 1.48% of total loans and leases at December 31, 1999, $2.1 million or
1.70% at December 31, 1998,  and $1.7 million or 1.40% at December 31, 1997. The
decrease in the allowance as a percentage of total loans since 1998 is primarily
due to the increase in loan balances in a generally strong economic environment.
It is the policy of  management  to maintain  the  allowance  for loan and lease
losses at a level adequate for losses inherent in the loan  portfolio.  Based on
information  currently  available to analyze  credit loss  potential,  including
economic factors,  overall credit quality,  historical delinquency and a history
of actual  charge-offs,  management  believes that the credit loss provision and
allowance is prudent and adequate.  However, no prediction of the ultimate level
of loans charged off in future years can be made with any certainty.

     The following table presents the activity within the allowance for loan and
lease losses for the years ended December 31, 1995,  1996,  1997, 1998 and 1999,
and  for  the  six  month  periods  ended  June  30,  1999  and  June  30,  2000

     The following  table  represents  the  allocation of the allowance for loan
losses as of December 31, 1995,  1996,  1997, 1998, and 1999, and as of June 30,
2000,  respectively.  The table sets forth the  allocation  of the allowance for
loan and lease  losses  by loan or lease  type as of the  dates  specified.  The
allocation of  individual  categories of loans  includes  amounts  applicable to
specifically  identified as well as unidentified losses inherent in that segment
of the loan portfolio and will necessarily change whenever management determines
that the risk characteristics of the loan portfolio have changed.

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

     Investment securities

     Tehama  Bancorp  maintains  a  securities   portfolio  consisting  of  U.S.
Treasury,  U.S.  Government  agencies  and  corporations,  state  and  political
subdivisions,  asset-backed and other securities. An independent custodian holds
investment  securities in safekeeping.  The provisions of Statement of Financial
Accounting  Standards  No.  115  require,   among  other  things,  that  certain
investments in debt and equity  securities be classified under three categories:
securities     held-to-maturity;     trading    securities;    and    securities
available-for-sale. Securities classified as held-to-maturity are to be reported
at  amortized  cost;  securities  classified  as  trading  securities  are to be
reported at fair value with unrealized  gains and losses included in operations;
and securities classified as available-for-sale are to be reported at fair value
with  unrealized  gains and losses  excluded  from  earnings  and  reported as a
separate  component of shareholders'  equity, net of tax. If a security is sold,
any gain or loss is recorded as a charge to earnings  and the equity  adjustment
is reversed.  At December 31, 1999, Tehama Bank held $26.8 million in securities
classified as available-for-sale,  compared with $34.3 million at year-end 1998.
At December 31, 1999,  unrealized gains of $1,000 and unrealized  losses of $1.4
million,  net of tax  benefits of  $561,000,  related to these  securities,  was
reflected  in   shareholders'   equity,   compared  with  $46,000  and  $81,000,
respectively,  for year-end 1998, net of tax benefits of $14,000. Tehama Bancorp
had $11.7 million of amortized cost in securities classified as held-to-maturity
securities at December 31, 1999, compared with $12.9 million at year-end 1998.

     The  following  table sets forth the maturity  distribution  and  estimated
market value of securities available-for-sale and the weighted-average yields of
these securities as of June 30, 2000, and December 31, 1999:

Deposits

     Deposits  represent  Tehama Bank's primary source of funds for  investment.
Deposits are primarily core deposits in that they are demand,  savings, and time
deposits  generated  from local  businesses and  individuals.  These sources are
considered to be relatively more stable, long-term deposit relationships thereby
enhancing  steady  growth of the deposit  base  without  major  fluctuations  in
overall deposit balances. Tehama Bank normally experiences a seasonal decline in
deposits  in the first  quarter of each year.  In order to assist in meeting its
funding needs, Tehama Bank maintains an unsecured  borrowing  arrangement with a
correspondent  bank in the amount of $7.5  million.  During  1998,  Tehama  Bank
applied  for,  and was accepted as a member of the Federal Home Loan Bank of San
Francisco  (the  "FHLB").  At June 30, 2000,  Tehama Bank held stock in the FHLB
which would allow Tehama Bank to borrow up to 25% of Tehama  Bank's total assets
using various loans or securities as  collateral.  The following  table presents
the composition of the deposit mix at December 31, 1997, 1998 and 1999, and June
30, 2000, respectively.

Off-Balance Sheet Items

     Tehama Bank has certain ongoing  commitments under operating leases.  These
commitments do not significantly  impact operating results.  Tehama Bank has not
entered into any contracts for financial derivative instruments such as futures,
swaps,  options etc. As of December 31, 1999,  commitments to extend credit were
the only financial  instruments  with  off-balance  sheet risk. Loan commitments
increased to $27.1 million from $17.8 million at December 31, 1998,  and standby
letters of credit  increased to $285,000 from $144,000 at December 31, 1998. The
commitments  represent  18.9% of total  loans at year end 1999  versus  14.7% in
1998.

Liquidity

     Liquidity management refers to Tehama Bancorp's ability to provide funds on
an ongoing basis to meet  fluctuations  in deposit  levels as well as the credit
needs and requirements of its clients. Both assets and liabilities contribute to
Tehama  Bancorp's  liquidity  position.   Short-term   borrowing   arrangements,
short-term  investments  and  securities,  and  loan  repayments  contribute  to
liquidity,  along  with  deposit  increases,  while  loan  funding  and  deposit
withdrawals decrease liquidity. Tehama Bank assesses the likelihood of projected
funding  requirements  by reviewing  historical  funding  patterns,  current and
forecasted economic conditions and individual client funding needs.  Commitments
to fund loans and  outstanding  standby letters of credit at June 30, 2000, were
approximately  $34.5 million and at December 31, 1999, were approximately  $27.4
million.  Such loans relate  primarily  to  revolving  lines of credit and other
commercial  loans,  and to real  estate  construction  loans.  Tehama  Bancorp's
sources of liquidity  consist of overnight  funds sold to  correspondent  banks,
unpledged  marketable  investments,  a  Federal  funds  line  of  credit  with a
correspondent  bank,  a line of credit  with the  Federal  Home Loan Bank of San
Francisco backed by a pledge of marketable investments, and loans held for sale.
Additional  liquidity can be obtained  through new  borrowings  from the Federal
Home Loan Bank of San  Francisco  secured by a pledge of  eligible  real  estate
loans or sales of  eligible  real  estate  loans or the  guaranteed  portion  of
government guaranteed loans in the secondary market,  promotional  activities to
attract new deposit  accounts  within Tehama  Bank's  market  areas,  increasing
interest-bearing  deposit  accounts by offering  higher rates of  interest,  and
raising  deposits,  primarily time certificates  deposit,  outside Tehama Bank's
market  area  through  use of  brokered  certificates  of  deposit or the use of
national certificate of deposit quotation services. Tehama Bank has not obtained
brokered  certificates  of deposit in the past and does not  currently  have any
brokered certificates of deposits on it books.

     A common  measurement  of  liquidity  for  banks  is the  ratio of loans to
deposits.  Tehama Bank's  target range for this ratio is 70-80%.  The lower this
ratio,  the higher Tehama Bank's  liquidity,  but at the cost of fewer assets in
the loan category,  which is the highest yielding earning asset.  This ratio for
Tehama Bank was 80.0% as of June 30, 2000,  compared to 77.0% as of December 31,
1999,  67.1% as of  December  31,  1998,  and  77.8% as of  December  31,  1997.
Management  monitors  the  likelihood  of  projected  funding   requirements  by
reviewing   historical  funding  patterns,   current  and  forecasted   economic
conditions, pending new loan fundings and individual customer needs.

     The principal cash requirements of Tehama Bancorp are for expenses incurred
in the support of  administration  and operations of Tehama Bank. For nonbanking
functions,  Tehama  Bancorp is dependent  upon the payment of cash  dividends by
Tehama Bank to service its  commitments.  Tehama  Bancorp  expects that the cash
dividends  paid by Tehama Bank to Tehama Bancorp will be sufficient to meet this
payment schedule.

Capital Resources

     Tehama  Bancorp  and Tehama  Bank are  subject to various  minimum  capital
requirements  as  defined by  regulation.  The  current  and  projected  capital
position  of Tehama  Bancorp  and the  impact  of  capital  plans and  long-term
strategies  are  reviewed  regularly by  management.  Tehama  Bancorp's  capital
position  represents  the  level  of  capital  available  to  support  continued
operations  and  expansion.   Tehama  Bancorp's   primary  capital  resource  is
shareholders'  equity,  which increased  $927,000 or 5.2% from the previous year
end, and in 1998  increased  $1.8 million or 11.3% from  December 31, 1997.  The
ratio of total risk-based capital to risk-adjusted  assets was 12.9% at June 30,
2000,  compared to 13.9% at December 31, 1999,  14.9% at December 31, 1998,  and
13.9% at December 31, 1997. Tier 1 risk-based  capital to  risk-adjusted  assets
was 11.7% at June 30, 2000,  compared to 12.6% at December  31,  1999,  13.6% at
December 31, 1998 and 12.7% at December 31, 1997.

     Federal regulation imposes upon all FDIC-insured  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 aid in
making the definition of bank capital uniform internationally. Under the Federal
Reserve Board's risk-based capital guidelines, Tehama Bancorp (on a consolidated
basis) and Tehama Bank under FDIC  guidelines  are  required  to maintain  total

<PAGE>134

risk-based  capital  equal to at least 8% of  risk-weighted  assets.  Assets and
off-balance sheet items are categorized by the guidelines according to risk, and
certain assets considered to present less risk than others permit maintenance of
capital at less than the 8% ratio.  The  guidelines  establish two categories of
qualifying capital: Tier 1 capital comprising core capital elements,  and Tier 2
comprising supplementary capital requirements. At least one-half of the required
capital must be  maintained  in the form of Tier 1 capital.  For Tehama Bank and
Tehama Bancorp,  Tier l capital  includes only common  stockholders'  equity and
retained  earnings,  but  qualifying  perpetual  preferred  stock  would also be
included  without  limit if Tehama  Bancorp  or Tehama  Bank were to issue  such
stock. Tier 2 capital includes, among other items, certain types of intermediate
term and perpetual  preferred  stock,  mandatory  convertible  debt  securities,
subordinated  debt and a  limited  amount  of the  allowance  for loan and lease
losses.

     The guidelines also require all insured  institutions to maintain a minimum
leverage  ratio of 3% Tier 1 capital  to total  average  assets  (the  "leverage
ratio").   The  Federal  Reserve  Board   emphasizes  that  the  leverage  ratio
constitutes a minimum  requirement for the most well-run banking  organizations.
All other  banking  organizations  are  required to maintain a minimum  leverage
ratio  ranging  generally  from 4% to 5%.  Tehama  Bancorp's  and Tehama  Bank's
required minimum leverage ratio is 4%.

     Federal  regulations  require that insured banks with significant  "trading
activity"  adjust their  risk-based  capital  calculations  in order to maintain
adequate  capital  against such market risk  exposures as changes in the general
level of interest  rates,  equity prices,  foreign  exchange rates and commodity
prices. Tehama Bank currently has no trading assets or liabilities. However, the
Uniform Financial Institutions Rating System (the "CAMELS" system) applicable to
Tehama  Bank has  included  for all bank  regulatory  examinations  since 1997 a
rating for sensitivity to market risk.  Ratings in this category are intended to
reflect the degree to which changes in interest rates,  foreign  exchange rates,
commodity prices or equity prices may adversely affect an institution's earnings
and capital.

     Prompt Corrective Action Regulations (the "PCA 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.  Tehama Bank has been  classified as a  well-capitalized  bank
since adoption of the PCA Regulations.

     The Board of Governors  and other federal  banking  agencies have adopted a
revised minimum leverage ratio for bank holding companies as a supplement to the
risk-weighted capital guidelines. The old rule established a 3% minimum leverage
standard for well-run banking  organizations  (bank holding companies and banks)
with diversified risk profiles. Banking organizations which did not exhibit such
characteristics  or had  greater  risk due to  significant  growth,  among other
factors, were required to maintain a minimum leverage ratio 1% to 2% higher. The
old rule did not take into account the implementation of the market risk capital
measure set forth in the federal regulatory agency capital adequacy  guidelines.
The revised  leverage  ratio  establishes  a minimum  Tier 1 ratio of 3% (Tier 1
capital to total assets) for the highest  rated bank holding  companies or those
that have implemented the risk-based capital market risk measure. All other bank
holding  companies  must  maintain a minimum Tier 1 leverage  ratio of 4% higher
leverage   capital  ratios  required  for  bank  holding   companies  that  have
significant financial and/or operational weaknesses, a high risk profile, or are
undergoing  or  anticipating  rapid  growth.  The old rule remains in effect for
banks, however, the federal regulatory agencies are currently continuing work on
a revised  leverage rule for banks.  The risk-based  capital ratios decreased in
1999 as the growth in total  assets  outpaced  the  increase in equity.  Capital
increased  by $2.2  million  from  income,  $602,000  from the exercise of stock
options,  and related tax benefit, and decreased $237,000 from the retirement of
common stock  through a common stock  repurchase  program and $854,000  from the
payment of a cash  dividend.  Capital  ratios are reviewed on a regular basis to

<PAGE>135

ensure that capital exceeds the prescribed  regulatory  minimums and is adequate
to  meet  Tehama  Bancorp's  future  needs.  All  ratios  are in  excess  of the
regulatory definition of "well capitalized."

Disclosure of Fair Value

     Statement of Financial  Accounting  Standards No. 107,  "Disclosures  about
Fair Value of Financial  Investments,"  requires the disclosure of fair value of
most  financial  instruments,  whether  recognized  or  not  recognized  in  the
financial  statements.  The intent of  presenting  the fair values of  financial
instruments  is to depict the market's  assessment  of the present  value of net
future cash flows  discounted  to reflect  both current  interest  rates and the
market's  assessment  of the risk  that  the  cash  flows  will  not  occur.  In
determining  fair values,  Tehama  Bancorp  used the  carrying  amount for cash,
short-term investments,  accrued interest receivable,  short-term borrowings and
accrued interest  payable as all of these  instruments are short term in nature.
Securities are reflected at quoted market values. Loans and deposits have a long
term time  horizon  which  requires  more  complex  calculations  for fair value
determination.  Loans are grouped into  homogeneous  categories  and broken down
between fixed and variable rate  instruments.  Loans with a variable rate, which
reprice immediately,  are valued at carrying value. The fair value of fixed rate
instruments  is estimated  by  discounting  the future cash flows using  current
rates. Credit risk and repricing risk factors are included in the current rates.
Fair value for nonaccrual loans is reported at carrying value and is included in
the net loan total.  Since the allowance  for loan and lease losses  exceeds any
potential adjustment for nonaccrual  valuation,  no further valuation adjustment
has been made.  Demand  deposits,  savings and certain money market accounts are
short term in nature so the carrying  value equals the fair value.  For deposits
that extend over a period in excess of four months,  the fair value is estimated
by discounting  the future cash payments using the rates  currently  offered for
deposits  of similar  remaining  maturities.  At 1999 year end,  the fair values
calculated  on Tehama  Bank's  assets are .84% below the carrying  values versus
1.46% above the carrying  values at year end 1998.  The change in the calculated
fair value  percentage  relates to the securities and loan categories and is the
result of changes in interest rates in 1999.

Inflation

     The impact of inflation on a financial  institution  differs  significantly
from that  exerted on  manufacturing  or other  commercial  concerns,  primarily
because its assets and liabilities are largely monetary.  In general,  inflation
primarily affects Tehama Bancorp indirectly through its effect on the ability of
its  customers  to repay loans,  or its impact on market rates of interest,  and
thus the ability of Tehama Bank to attract loan customers. Inflation affects the
growth of total assets by increasing the level of loan demand,  and  potentially
adversely  affects  Tehama  Bancorp's  capital  adequacy  because loan growth in
inflationary  periods may increase more rapidly than capital.  Interest rates in
particular are significantly  affected by inflation,  but neither the timing nor
the magnitude of the changes coincides with changes in the Consumer Price Index,
which  is  one of  the  indicators  used  to  measure  the  rate  of  inflation.
Adjustments in interest rates may be delayed because of the possible  imposition
of  regulatory  constraints.  In  addition  to its  effects on  interest  rates,
inflation  directly  affects  Tehama  Bancorp  by  increasing  Tehama  Bancorp's
operating expenses.  In management's opinion, the effect of inflation during the
three-year  period ended December 31, 1999,  has not been  significant to Tehama
Bancorp's financial position or results of operations.

Asset/Liability Management

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

     Generally, asset/liability management is a comprehensive integrated process
for  overall  financial   management.   The  major  purpose  of  asset/liability
management  is  to ensure  that  Tehama  Bank's  primary  financial  objectives,

<PAGE>136

profitability,  capital  adequacy,  risk tolerance,  and liquidity are achieved.
Through asset/liability  management,  Tehama Bank develops a methodology,  which
can be used to optimize the critical  risk/return  tradeoff that the institution
faces in pricing,  maturity  selection,  funds  allocation,  and other decisions
every day.  Correct asset  liability  management  enables Tehama Bank to achieve
earnings which are adequate and consistent,  thereby enabling the achievement of
profitability  and risk  objectives.  The primary  capital  objective is capital
preservation,  which is achieved by controlling interest rate and credit-related
risk exposure, and by the retention of earnings. Tehama Bank will also strive to
ensure  that each  dollar of  capital  is  optimally  leveraged.  Tehama  Bank's
asset/liability management program consists of four major disciplines:  interest
rate risk management, net interest margin/spread management, capital management,
and liquidity  management.  The formal integration of these  inter-related areas
into an effective asset/liability  management program that includes a process of
planning,  organizing,  and controlling all of Tehama Bank's financial resources
will  enable  Tehama  Bank to achieve a planned  net  interest  margin over time
within  acceptable  risk levels.  Tehama  Bancorp's  asset/liability  management
policy is designed  to ensure  that  Tehama Bank is managed to provide  adequate
liquidity, maintain adequate capital, and, provide a satisfactory and consistent
level of profits, within suitable interest rate risk constraints.

     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 under changing interest environments.


                           BUSINESS OF TEHAMA BANCORP

General

     Tehama  Bancorp was organized as a California  corporation  in January 1997
for the purpose of reorganizing  Tehama Bank as the  wholly-owned  subsidiary of
Tehama Bancorp. This transaction was approved by the shareholders of Tehama Bank
at the 1997 Annual  Meeting of Tehama  Bank,  and was made  effective  as of the
close of business June 30, 1997.  Tehama Bancorp is registered with the Board of
Governors of the Federal Reserve System (the "Federal  Reserve Board") as a bank
holding  company  under the Bank Holding  Company Act of 1956,  as amended,  and
reports  annually to and is examined by the Federal  Reserve  Board.  The common
stock  of  Tehama  Bancorp  is  registered  with  the  Securities  and  Exchange
Commission (the "SEC") pursuant to section 12(g) of the Securities  Exchange Act
of 1934, as amended (the  "Exchange  Act"),  and Tehama  Bancorp files  periodic
reports and proxy  materials  with the SEC pursuant to sections 13 and 14 of the
Exchange Act.

     Tehama Bank is Tehama Bancorp's only  consolidated  subsidiary.  Aside from
engaging  indirectly  in the  business  conducted  by  Tehama  Bank,  which  was
incorporated  March 15, 1984,  and  commenced  banking  operations on August 30,
1984,  Tehama Bancorp engages in leasing  activities  through Bancorp  Financial
Services, of which it is the owner of a one-half interest.

Offices

     The headquarters of Tehama Bank and Tehama Bancorp are located at 239 South
Main Street, Red Bluff, California. The main office of Tehama Bank is located at
333 Main Street, Red Bluff,  California,  and branch offices are located at 7843
Highway 99E, in the unincorporated  community of Los Molinos,  Tehama County; at

<PAGE>137

     Tehama Bank's main office in Red Bluff and its Chico,  Orland,  Willows and
Redding offices all maintain the same lobby hours (9:00 A.M.  through 5:00 P.M.,
Monday through  Thursday,  and 9:00 A.M.  through 6:00 P.M. on Fridays).  Tehama
Bank's Los Molinos office  maintains lobby hours of 9:00 A.M. through 4:00 P.M.,
Monday  through  Thursday,  and 9:00 A.M.  through 5:00 P.M. on Friday.  The Red

transactions  during the hours of 8:00 A.M.  through 5:30 P.M.,  Monday  through
Thursday,  and 8:00 A.M.  through  6:00  P.M.  on  Friday.  The  Redding  office
maintains  a  drive-up  window  for  transactions  during the hours of 8:00 A.M.
through 5:00 P.M., Monday through  Thursday,  and 8:00 A.M. through 6:00 P.M. on
Friday.  Additionally,  ATMs are  available  at the Red  Bluff,  Chico,  Orland,
Willows  and  Redding  offices.  The Los  Molinos  office does not have either a
drive-up window or an ATM.

Services

     Tehama Bank  conducts a commercial  banking  business  including  accepting
demand,  savings  and time  deposits,  issuing  letters  of  credit,  and making
commercial,  real estate,  and consumer loans. It also offers  installment  note
collection, issues cashier's checks, sells traveler's checks, acts as a licensed
merchant bankcard sales clearer,  and provides the following:  24-hour automated
teller service,  bank-by-mail and night depository services, safe deposit boxes,
and other  customary  banking  services.  Most of Tehama  Bank's  customers  are
individuals and small  businesses.  Tehama Bank serves as a merchant  processor,
under contract with a third party,  for processing  credit card  transactions of
selected merchants. Tehama Bank also provides cash and cash services to selected
privately-owned ATMs.

     Tehama  Bank  is a  member  bank of the  Federal  Reserve  System,  and the
accounts  of its  depositors  are  insured  by the  FDIC to the  maximum  amount
provided  by law.  Tehama Bank does not offer  trust  services or  international
banking services and does not plan to do so in the near future.

Leasing Activities

     During 1996, Tehama Bank entered into a joint venture with Humboldt Bank to
organize and share equally in a subsidiary  leasing company.  Bancorp  Financial
Services was  organized as a California  corporation  on November 25, 1996,  and
Tehama Bank and Humboldt each contributed $2 million towards its  capitalization
as of January 2, 1997.  Effective  April 1, 1998  Tehama  Bank  transferred  its
interest in Bancorp  Financial  Services to Tehama Bancorp.  Tehama Bank extends
credit to Bancorp  Financial  Services and purchases (on a  non-recourse  basis)
leases  originated  by  Bancorp  Financial  Services,  both of  which  types  of
transactions  provide additional  funding for its operations.  Bancorp Financial
Services'  offices are located at 2540 Venture Oaks, in Sacramento,  California.
Bancorp Financial  Services engages in equipment leasing in the so-called "small
ticket" segment of the industry,  which generally includes leases of $100,000 or
less.  Bancorp Financial  Services' business plan is to acquire such leases from
independent  lessors or brokers through  brokerage or discount,  to service them
and, at predetermined intervals, package and resell them to investors. Income to
Tehama Bancorp is generated  through  spreads on its lease  portfolio,  gains on
sales,  and ongoing  fees and  charges.  Bancorp  Financial  Services'  board of
directors includes Chief Executive Officer Kevin D. Cochrane, three members from
the  Humboldt  Bancorp  board of  directors  and three  members  from the Tehama
Bancorp board of directors.

Lending Activities

     As of the close of  business  on  December  31,  1999,  Tehama  Bank's loan
portfolio  consisted  of $68.1  million in real  estate  loans  (including  $9.0
million in real estate  construction  loans and $23.7 million in commercial real
estate  loans),  $33.8 million in commercial  loans  (including  $6.2 million in
commercial  leases),  and $43.2 million in installment  loans to individuals for
household,  family and other personal  expenditures.  Comparable segments of the
loan portfolio as of December 31, 1998, were carried at values of $59.3 million,
$31.4 million, and $31.9 million,  respectively. As of December 31, 1997, Tehama
Bank's portfolio consisted of $62.3 million in real estate loans (including $8.9
million in real estate  construction  loans),  $17.9 million in commercial loans

<PAGE>138

(including $2.4 million in commercial leases),  and $42.0 million in installment
loans to individuals for household, family and other personal expenditures.

     As of December 31, 1999, 1998 and 1997, Tehama Bank had outstanding  credit
commitments  (including standby letters of credit) of $27.4 million, $18 million
and $17.5,  respectively.  Tehama Bank expects 40% of its commitments to lend as
of December 31, 1999, will not be exercised within the year 2000.

     At December 31, 1999, Tehama Bank's loan limit to individual  customers for
unsecured  loans was $2.5 million and the limit for  unsecured and secured loans
combined was $4.3  million.  For  customers  desiring  loans in excess of Tehama
Bank's lending limits,  Tehama Bank may loan on a participation  basis, with its
correspondent  banks  taking the  amount of the loan in excess of Tehama  Bank's
lending limits.  In other cases,  Tehama Bank may refer such borrowers to larger
banks or other lending institutions.  No material portion of Tehama Bank's loans
is concentrated within a single industry or group of related industries.

Deposits

     Approximately  48% of Tehama Bank's  deposits are attracted from and around
the city of Red Bluff. A material portion of Tehama Bank's deposits has not been
obtained from a single  person or a few persons,  the loss of any one or more of
which would have a  materially  adverse  effect on the  business of Tehama Bank.
Furthermore,  (1) the extent to which the business of Tehama Bank is seasonal is
insignificant;  (2) the importance of, and risks  attendant to, foreign  sources
and applications of Tehama Bank's funds is negligible; and (3) Tehama Bank as of
December  31,  1999,  held  $70,203 in United  States  agency  deposits and $1.9
million in local agency deposits.

Employees

     At September  30, 2000,  Tehama Bank employed 120 persons,  including  four
executive  officers  and a total of 47 other  officers.  None of  Tehama  Bank's
employees  is  presently  represented  by a union or covered  under a collective
bargaining  agreement.  Management  of Tehama Bank  believes  that its  employee
relations are excellent.

Competition

     Tehama Bank's primary service areas include Tehama, Butte, Glenn and Shasta
counties, and contain a total of 88 competitive banking offices, of which 37 are
offices of major chain banking  systems and 51 are offices of other  independent
banks.  On June 30,  1999,  amounts  reported  by  state  and  federal  agencies
indicated that these banking  offices held  approximately  $3.1 billion in total
deposits,  averaging  approximately  $35.2 million per office. The service areas
also contain the offices of 11 savings and loan associations, with approximately
$694 million in total deposits as of June 30, 1999.

     The banking business in California generally,  and in Tehama Bank's primary
service areas specifically, is highly competitive with respect to both loans and
deposits and 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  Tehama  Bank  are  their  ability  to  finance  wide  ranging
advertising  campaigns  and to allocate  their  investment  assets to regions of
highest  yield and  demand.  Such banks  offer  certain  services  such as trust
services and international banking which are not offered directly by Tehama Bank
(but are offered indirectly through  correspondent  institutions) and, by virtue
of their greater total  capitalization  (legal  lending  limits to an individual
customer are limited to a percentage of a bank's total capital  accounts),  such
banks have  substantially  higher  lending  limits than does Tehama Bank.  Other
entities,  both  governmental and private,  seeking to raise capital through the
issuance and sale of debt or equity  securities,  also provide  competition  for
Tehama Bank in the acquisition of deposits.

     Commercial  banks also compete  with other types of financial  institutions
(savings  associations  and credit unions) and with other markets for funds. For
instance,   yields  on  corporate  and  government  debt  securities  and  other
commercial  paper  affect the  ability of  commercial  banks to attract and hold

<PAGE>139

deposits.  Commercial  banks also compete for available  funds with money market
instruments.  In periods of high  interest  rates,  such money market funds have
provided  substantial  competition to banks for deposits,  and it is anticipated
they may continue to do so in the future.

     In order to  compete  with  other  financial  institutions  in its  primary
service areas,  Tehama Bank relies  principally upon (a) direct personal contact
by officers,  directors,  employees and shareholders,  (b) extended lobby hours,
and (c) specialized  promotions.  Tehama Bank focuses its promotional activities
on the advantages of dealing with an independent bank.

Properties

     Tehama Bank leases its Orland and Redding branch offices, and owns the land
and  buildings in which its Chico,  Los Molinos and Willows  branch  offices are
located. Tehama Bank leases from a director of Tehama Bank the building in which
its Red Bluff  branch  office is located,  leases the  building in which its Red
Bluff  administrative  headquarters is located and,  subject to the ground lease
described below, owns the building (adjacent to its  administrative  offices and
operations center) in which its loan servicing operations are conducted.  Tehama
Bank's  total  rentals  for  premises  and  equipment  for fiscal year 1999 were
approximately  $202,933  and its  minimum  future  commitments  under  operating
leases, as of December 31, 1999, totaled $1.3 million.

     Tehama Bank  acquired the right to purchase its former head office in which
its loan servicing operations are now conducted,  by assignment in 1988 from two
of Tehama Bank's directors,  Orville Jacobs and John Koeberer.  The building,  a
two-story commercial building with approximately 7,700 square feet of space, was
acquired  for a price  of  $25,000.  The  assignment  contains  a right of first
refusal in favor of Messrs.  Jacobs and Koeberer  whereby they have the right to
repurchase the building from Tehama Bank in the event that Tehama Bank elects to
sell,  vacate  or  sublet  the  building  to a  party  other  than  a  financial
institution. This right of first refusal has a term concurrent with the terms of
the  underlying  ground lease.  The ground lease provides for an initial term of
eight (8) years that  terminated on December 31, 1988.  It further  provides for
four (4) additional  options to extend the term of the ground lease for a period
of eight (8) years each, or a total of 32 years. The base rent is to be adjusted
during each  extension  term in accordance  with the fair market rental value of
the land as of the  commencement  of the applicable  extension term. The current
lease term, at a monthly rental of $2,310, expires December 31, 2004.

     Tehama Bank's administrative  offices are leased for an initial term of ten
years,  and the lease further  provides for one additional  option to extend the
term of the lease for a period of five  years.  The  current  lease  term,  at a
monthly rental of $2,860, expires March 15, 2004.

     Tehama Bank's operations center is leased on a month-to-month basis, with a
60 day notice of termination requirement, for a monthly rental of $500.

     Tehama  Bank  acquired  the  Willows  office at a combined  value (land and
building) of  approximately  $340,000 in connection with its 1997 acquisition of
deposits and assets of Wells Fargo Bank branches  located in Willows and Orland,
California.  The building area is  approximately  6,400 square feet.  The Orland
office is a leased  facility also  acquired in  connection  with the Wells Fargo
Bank  transaction.  Tehama Bank  assumed  existing  leases on the  building  and
adjacent  parking  lot with the  second of three  five-year  options  commencing
August 1, 1997.  Monthly  payments on the building and lot leases are $2,210 and
$350, respectively.

     Tehama Bank during 1999 moved its branch in Red Bluff to a building  which,
with an adjacent  parking area,  Tehama Bank leases from director  Harry Dudley.
The lease provides for an initial term of five years,  and further  provides for
four  additional  options  to extend  the term of the lease for a period of five
years each, or a total of 20 years.  The current lease term, at a monthly rental
of $2,900 for the building and $575 for the parking lot, expires August 1, 2004.
The base  monthly  rents are to be increased  by 2% for each  successive  twelve
month  period of the leases  beginning in year two and  continuing  through year
ten,  encompassing the  initial period  and the first extension  option  period.

<PAGE>140

Monthly lease payments in years eleven  through  twenty-five,  encompassing  the
second through fourth extension option periods shall be negotiated each time the
lease is extended.

     The Redding  office is  currently  leased for an initial term of ten years,
and further provides for two additional  options to extend the term of the lease
for a period of five years  each,  or a total of ten years.  The  current  lease
term, at a monthly rental of $7,454, expires July 15, 2008.

Legal Proceedings

        There are no material  pending legal  proceedings,  other than ordinary,
routine litigation incidental to Tehama Bancorp's and Tehama Bank's business, to
which  Tehama  Bancorp  or  Tehama  Bank is a party  or of  which  any of  their
properties are subject.

                  SUPERVISION AND REGULATION OF TEHAMA BANCORP

     Tehama Bancorp and Tehama Bank are extensively regulated under both federal
and state laws and regulations,  just as Humboldt Bancorp and its  subsidiaries.
For a general  description of these laws and  regulations,  see "Supervision and
Regulation of Humboldt Bancorp." Below are the results of specific  applications
of those laws to Tehama Bancorp and Tehama Bank.

Deposit Insurance Assessments

     Tehama Bank's deposit insurance  assessment rate is at the lower end of the
range  (from $0 to  $0.27  per $100 of  deposits)  imposed  by the FDIC in 1995.
Tehama Bank does not anticipate that its deposit  insurance  assessment for 2000
will differ materially from its assessment for 1999 ($18,236).

Capital Requirements

     As  of  December  31,  1999,  Tehama  Bancorp's  and  Tehama  Bank's  total
risk-based capital ratios were approximately 13.9% and 12.0%, and their leverage
ratios were  approximately  9.4% and 7.9%,  respectively.  Tehama  Bancorp's and
Tehama Bank's  required  minimum  leverage  ratio is 4%. It is not expected that
compliance  with  the  risk-based   capital   guidelines  or  minimum   leverage
requirements  will have a  materially  adverse  effect on the business of Tehama
Bancorp or Tehama Bank in the  reasonably  foreseeable  future.  Nor does Tehama
Bank  expect  that its  sensitivity  to market  risk will  adversely  affect its
overall CAMELS rating.

     Tehama Bank has been classified as a  well-capitalized  bank since adoption
of the Prompt Corrective Action Regulations.

Community Reinvestment Act

     Community  Reinvestment  Act ("CRA")  regulations  effective  as of July 1,
1995,  evaluate Tehama Bank's lending to low and moderate income individuals and
businesses  across  a  four-point  scale  from   "outstanding"  to  "substantial
noncompliance,"  and are a factor in regulatory review of applications to merge,
establish  new branches or form bank holding  companies.  In addition,  any bank
rated in "substantial  noncompliance" with the CRA regulations may be subject to
enforcement proceedings.  Tehama Bank has a current rating of "satisfactory" CRA
compliance.

Safety and Soundness Standards

     Federal  bank  regulations  establish  for insured  financial  institutions
safety and soundness  standards for (1) internal controls,  information  systems
and internal audit systems; (2) loan documentation; (3) credit underwriting; (4)
interest rate exposure;  (5) asset growth; (6) compensation,  fees and benefits;

<PAGE>141

and (7) excessive  compensation.  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.  Agencies may elect to initiate enforcement action
in  certain  cases  where  failure  to meet one or more of the  standards  could
threaten the safe and sound  operation of the  institution.  Tehama Bank has not
been and  does not  expect  to be  required  to  submit a safety  and  soundness
compliance  plan  because of a failure  to meet any of the safety and  soundness
standards.

The Financial Services Modernization Act of 1999

     Tehama Bancorp and Tehama Bank have not  determined  whether or when either
of them may seek to acquire  and  exercise  new powers or  activities  under the
Financial  Services   Modernization  Act  of  1999,  and  the  extent  to  which
competition will change among financial institutions affected by the Act has not
yet become apparent.

     The  following  is a  brief  account  of the  business  experience  of each

Stock Option Plans

     The Tehama  Bancorp 1994 Stock Option Plan (the "1994 Plan") was terminated
for the purpose of granting new options on May 14, 1999,  the effective  date of
the 1999 Stock Option Plan (the "1999  Plan")  approved by the  shareholders  of
Tehama  Bancorp at the 1999 Annual Meeting of  Shareholders.  Options for 79,437
shares of Common Stock of Tehama Bancorp remain outstanding under the 1994 Plan.

     Under the 1999 Plan,  nonstatutory  (sometimes also called "non-qualified")
options to purchase  shares of Tehama  Bancorp's  Common Stock may be granted to
employees,  directors and consultants of Tehama Bancorp,  and incentive  options
may be  granted  to  employees.  The 1999 Plan is  administered  by the board of
directors,  which selects the  individuals to whom options will be granted,  the
type of option to be granted,  the exercise price of each option,  the number of
shares covered by such option and the other terms and conditions of each option,
including  the vesting  schedule.  By terms of the 1999 Plan,  each  director of
Tehama  Bancorp  was  granted   automatically  on  May  17,  1999,  a  five-year
non-statutory option for 5,000 shares of Common Stock,  exercisable at the price
of $11.875 per share and vesting in increments of 1,000 shares  immediately  and
on the first through the fourth anniversaries of the grant date.

     The  exercise  price of each  option  granted  pursuant  to the  1999  Plan
ordinarily  may not be less than one hundred  percent  (100%) of the fair market
value of the stock subject to the option on the date the option is granted,  and
no option may have a term exceeding ten years. All options (except for automatic
option grants to directors of Tehama  Bancorp)  terminate  upon  termination  of
employment,  but may be  exercised  (to the extent  vested) for varying  periods
after termination of employment.  During an optionee's lifetime,  the optionee's
incentive  options  may  be  exercised  only  by  him  or  her  and  may  not be
transferred. An optionee's nonstatutory options also are not transferable during
the optionee's lifetime,  except to the extent otherwise permitted in the option
agreement. The exercise price of shares issued pursuant to exercise of an option
under the  1999 Plan may always be  paid in cash and, in addition,  may be paid,

<PAGE>145

in the  discretion  of the board with (1) Company  shares  already  owned by the
optionee, valued at their fair market value, (2) the proceeds of a resale of the
shares by an  authorized  securities  broker or (3) the proceeds of a loan (by a
securities  broker or lender approved by Tehama Bancorp)  secured by a pledge of
the shares acquired by the exercise.

     The board has  authority  to delegate its  administrative  powers to one or
more  committees  of the board.  A total of  562,947  shares  are  reserved  for
issuance under the 1999 Plan, of which 460,905 are reserved for options  granted
and outstanding under the 1999 Plan. As of the date of this document,  there are
approximately  125  persons  who are  officers or  employees  of Tehama  Bancorp
eligible to receive  option grants under the 1999 Plan;  no current  director is
eligible to receive a further  grant in addition to the option  granted in 1999.
The board may amend,  suspend or terminate the 1999 Plan at any time and for any
reason.

     If  Tehama  Bancorp  at any  time  succeeds  to  the  business  of  another
corporation through merger or consolidation, or through the acquisition of stock
or assets of such  corporation,  options  may be granted  under the 1999 Plan in
substitution of options previously granted by such other corporation to purchase
shares  of  its  stock,  which  options  are  outstanding  at  the  date  of the
succession.

     The shares  reserved for the 1999 Plan,  and  outstanding  options  granted
under the 1999 Plan,  are subject to  adjustment of their number or price in the
event  of  a  subdivision  of  the  outstanding  shares  of  Tehama  Bancorp,  a
declaration  of a dividend  payable in such  shares or in a form other than such
shares  in an amount  that has a  material  effect  on the value of  outstanding
shares,   a  combination  or   consolidation   of  the  outstanding   shares,  a
recapitalization,  a spinoff or a similar  occurrence.  In the event that Tehama
Bancorp is a party to a merger or other reorganization, outstanding options will
be subject to the agreement of merger or  reorganization,  which may provide (by
way of example) for the assumption of outstanding options under the 1999 Plan by
the  surviving  corporation  or its  parent,  for their  continuation  by Tehama
Bancorp (if Tehama  Bancorp is the surviving  corporation),  or for payment of a
cash  settlement  per share of the option  equal to the  difference  between the
amount to be paid for one share of Tehama  Bancorp under such  agreement and the
exercise  price per share of the option,  in all cases  without  the  optionees'
consent.  Any  cancellation  of options may not occur until after optionees have
been  notified  of  the  merger  or  reorganization   and  have  had  reasonable
opportunity to exercise their exercisable options.

        The following table sets forth,  with respect to the executive  officers
named in the Summary Compensation Table,  information concerning options granted

Salary Continuation Agreements

     In order to  provide  long-term  incentive  to  selected  senior  executive
officers, the Bank in 1993 entered into Executive Salary Continuation Agreements
(each an "SCA") with three former and one current  senior  executive  officer of
Tehama  Bancorp,  Chief  Executive  Officer  William P.  Ellison.  An  agreement
amending the SCA with Mr.  Ellison also was entered into  effective in 1998, and
SCAs were  entered  into  subsequently  with other  officers of Tehama  Bancorp,
including Senior Vice Presidents W. Steven Gilman and Wayne N. Shaffer.

     Benefits payable under the SCAs are intended by Tehama Bancorp to be funded
by  single-premium  life  insurance  policies which were purchased in connection
with  entering  into the  SCAs and of which  Tehama  Bancorp  is the  owner  and
beneficiary.  The total amount of such  premiums  paid by the Bank in connection
with all SCAs entered into is $3,015,000.  Notwithstanding the existence of such
policies of  insurance,  however,  the SCAs create no rights or interests in the
property or assets of Tehama  Bancorp,  the sole  obligation  of Tehama  Bancorp
under the SCAs is an unfunded and unsecured  promise to pay money in the future,
and the status of any person who may assert a claim  pursuant  to an SCA is that
of an unsecured general creditor of Tehama Bancorp.

     Generally,  each SCA provides the named executive  officer with a specified
annual money benefit (the "Annual  Benefit")  payable to the executive or to his
named  beneficiary or surviving spouse or estate, in that order, for a period of
up to  fifteen  years  following  the  executive's  retirement  upon or  after a
specified  retirement age. If the executive  should die or become disabled prior
to such  specified  retirement  age, a  percentage  of the Annual  Benefit (on a
sliding  upward scale  depending  upon the number of years which elapse  between
execution of the SCA and the  executive's  early death or  disability)  would be
payable.

     No Annual  Benefit is payable if the  executive's  employment is terminated
for cause or the executive  voluntarily  terminates his  employment  with Tehama
Bancorp prior to his specified  retirement  age, but the full Annual  Benefit is
payable if the  executive's  employment  with Tehama  Bancorp is  terminated  by
Tehama Bancorp without cause or in connection with a change in control of Tehama
Bancorp. The amount of the Annual Benefit also is subject to reduction if in any
year it exceeds the  compensation  expense which (with respect to the payment of
such Annual Benefit)  Tehama Bancorp may deduct under the Internal  Revenue Code
or if any portion of the Annual Benefit not waived by the executive  constitutes
an "excess parachute" payment under the Code.

     Subject to such  contingencies,  the following table sets forth information
regarding  benefits payable under the SCAs which are currently in effect between
Tehama  Bancorp and the  executive  officers  named in the Summary  Compensation
Table.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Indebtedness of Management

     Tehama  Bancorp  has  had  and  expects  to  have  in the  future,  banking
transactions in the ordinary  course of its business with  directors,  principal
officers,  their respective  associates and members of their immediate families.
All loans and  commitments  to lend extended to such persons  during 1999 by the
Bank were made in accordance with Bank policy on  substantially  the same terms,
including  interest rates and  collateral,  as those  prevailing at the time for
comparable transactions with other persons and, in the opinion of Tehama Bancorp
and the Bank,  did not involve  more than the normal risk of  collectibility  or
present other unfavorable features.

Transactions with Management

     During 1999,  Tehama Bank placed radio  advertising  in the gross amount of
$2,924 with  agencies  employed by stations  owned and operated by director Gary
Katz,  and paid  brokerage  commissions  in the total  amount of  $14,369  to an
insurance  agency owned in part by director Gary Napier for insurance  purchased
through the agency.  In addition,  lease payments in the gross amount of $10,425
were paid to director Harry Dudley to rent Tehama Bank's relocated branch in Red
Bluff.  No other business  transactions of any kind existed or were entered into
between Tehama Bancorp and its directors and their affiliates.

                          INDEPENDENT AUDITOR'S REPORT



Board of Directors
Humboldt Bancorp and Subsidiaries
Eureka, California


We have audited the accompanying consolidated balance sheets of Humboldt Bancorp
(Bancorp)  and  Subsidiaries  as of December 31, 1998 and 1999,  and the related
consolidated statements of operations,  changes in stockholders' equity and cash
flows for each of the three years in the period ended  December 31, 1999.  These
financial  statements are the  responsibility of the Bancorp's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  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 financial  statements  referred to above present fairly, in
all material respects,  the consolidated  financial position of Humboldt Bancorp
and Subsidiaries at December 31, 1998 and 1999, and the consolidated  results of
their operations and their  consolidated  cash flows for each of the three years
in the period ended  December 31, 1999, in conformity  with  generally  accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                          December 1997, 1998 and 1999


NOTE A--SIGNIFICANT ACCOUNTING POLICIES

Business:  Humboldt Bancorp (Bancorp), formed in 1995, is a bank holding company
whose  principal  activity is the ownership and  management of its  wholly-owned
subsidiaries,   Humboldt  Bank  and  Capitol  Valley  Bank.  Humboldt  Bank  was
incorporated  on March 13, 1989 and opened for business on  September  13, 1989.
Capitol  Valley  Bank was  incorporated  on  December  17,  1998 and  opened for
business on March 3, 1999.  Bancorp and the Banks operate under California state
charters and are subject to regulation,  supervision and regular  examination by
the Federal Reserve Bank,  Department of Financial  Institutions and the Federal
Deposit  Insurance  Corporation.  The  regulations of these agencies govern most
aspects of the  Banks'  business.  The  accounting  and  reporting  policies  of
Humboldt Bancorp and  Subsidiaries  conform with generally  accepted  accounting
principles and general practices within the banking industry.

Principles of Consolidation:  The consolidated  financial statements include the
accounts of  the Bancorp  and its wholly-owned  subsidiaries,  Humboldt Bank and
Capitol Valley Bank. All material  intercompany  accounts and transactions  have
been eliminated.

Nature of  Operations:  Bancorp is locally  owned and  operated  and its primary
service  area  is  the   communities   of  Northern   California.   Through  its
subsidiaries,  Bancorp's  business is primarily focused on servicing the banking
needs of individuals living and working in the Bancorp primary service areas and
local  businesses,  including  retail,  professional  and  real  estate  related
enterprises in those service areas.  Bancorp offers a broad range of services to
individuals  and businesses  with an emphasis upon  efficiency and  personalized
attention.  Bancorp provides a full line of consumer  services,  and also offers
specialized  services  to  small  businesses,   middle  market  companies,   and
professional  firms, such as courier services and appointment  banking.  Bancorp
offers personal and business checking and savings accounts (including individual
interest-bearing   negotiable  orders  of  withdrawal  ("NOW")  accounts  and/or
accounts combining checking and savings accounts with automatic transfers),  IRA
and Keogh  accounts,  time  certificates of deposit and direct deposit of social
security,  pension  and  payroll  checks.  It also makes  available  commercial,
construction, accounts receivable, inventory, automobile, home improvement, real
estate, office equipment,  leasehold improvement, lease receivable financing and
other consumer loans (including  overdraft  protection lines of credit),  drafts
and  standby  letters of credit,  credit  card  activities  to both  individuals
(including both secured and unsecured credit cards) and merchants and travelers'
checks (issued by an independent entity).

Use of Estimates:  The  preparation of financial  statements in conformity  with
generally accepted  accounting  principles 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. Actual results could differ from those estimates.

Investment Securities:  Securities are classified as held-to-maturity if Bancorp
has both the intent  and  ability to hold  those  debt  securities  to  maturity
regardless  of  changes  in market  conditions,  liquidity  needs or  changes in
general economic  conditions.  These securities are carried at cost adjusted for
amortization  of premium and  accretion  of  discount,  computed by the interest
method over their contractual lives.

Securities are classified as available-for-sale if Bancorp intends to hold those
debt  securities  for an  indefinite  period  of time,  but not  necessarily  to
maturity. Any decision to sell a security classified as available-for-sale would
be based on various factors,  including significant movements in interest rates,
changes in the maturity mix of Bancorp assets and liabilities,  liquidity needs,
regulatory  capital   considerations  and  other  similar  factors.   Securities
available-for-sale are carried at fair value. Unrealized holding gains or losses
are  reported as increases or  decreases  in  stockholders'  equity,  net of the
related deferred tax effect.  Realized gains or losses,  determined on the basis
of the cost of specific securities sold, are included in earnings.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

                          December 1997, 1998 and 1999


NOTE A--SIGNIFICANT ACCOUNTING POLICIES (Continued)

The Bancorp's investments in mortgage-backed  securities represent participating
interests in pools of long-term first mortgage loans  originated and serviced by
issuers of the  securities.  Mortgage-backed  securities  are  carried at unpaid
principal  balances,  adjusted for unamortized  premiums and unearned discounts.
Premiums and discounts are amortized  using methods  approximating  the interest
method  over  the  remaining  period  to  contractual  maturity,   adjusted  for
anticipated prepayments.

Loans and Leases Held for Sale:  Bancorp sells  mortgage  loans,  the guaranteed
portion  of  Small  Business  Administration  (SBA)-guaranteed  loans  and  loan
participations  (with  servicing  retained)  for  cash  proceeds  equal  to  the
principal  amount of loans,  participation  or leases  with  yield  rates to the
investor  based upon the current  market rate. In accordance  with  Statement of
Financial  Standards  (SFAS) No. 125,  Accounting for Transfers and Servicing of
Financial  Assets and  Extinguishment  of Liabilities,  Bancorp records an asset
representing  the right to  service  loans for  others  when it sells a loan and
retains the servicing  rights.  The total cost of  originating or purchasing the
loans is allocated  between the loan and the  servicing  rights,  based on their
relative fair values.  Fair value is estimated by discounting  estimated  future
cash flows from the  servicing  assets  using  discount  rates that  approximate
current market rates and using current  expected future  prepayment  rates.  The
servicing  rights  are  amortized  in  proportion  to,  and over the  period of,
estimated net servicing income, assuming prepayments.

SFAS No. 125 also required the assessment of all  capitalized  servicing  rights
for  impairment  based on current  fair value of those  rights.  For purposes of
evaluating and measuring  impairment,  Bancorp stratifies servicing rights based
on the type and interest rates of the underlying  loans.  Impairment is measured
as the  amount by which the  servicing  rights for a stratum  exceed  their fair
value.

A premium  over the  adjusted  carrying  value is received  upon the sale of the
guaranteed  portion  of an SBA  loan.  Bancorp's  investment  in an SBA  loan is
allocated among the sold and retained portions of the loan based on the relative
fair  value  of each  portion  at the  time of loan  origination,  adjusted  for
payments and other  activities.  Because the portion  retained does not carry an
SBA guarantee,  part of the gain  recognized on the sold portion of the loan may
be deferred and  amortized  as a yield  enhancement  on the retained  portion in
order to obtain a market equivalent yield.

Loans  and  leases  held for sale are  recorded  at the  lower of cost or market
determined on an aggregate basis.

Loan and Leases:  Loans and leases are stated at the amount of unpaid principal,
less the  allowance  for losses,  net deferred  loan fees and costs and unearned
income.  Interest  on loans is  accrued  and  credited  to  income  based on the
principal amount outstanding. Unearned income on installment loans is recognized
as  income  over the term of the  loans  using a method  that  approximates  the
interest method.

Bancorp's leasing operations consist principally of the leasing of point-of-sale
terminals, printers for credit card vouchers and related equipment. Bancorp also
has  purchased  small  equipment  leases  from  Bancorp  Financial  Services,  a
subsidiary of the Bancorp.  All of Bancorp's leases are classified and accounted
for as direct financing leases.  Under the direct financing method of accounting
for leases, the total net rentals  receivable under the lease contracts,  net of
unearned income,  are recorded as a net investment in direct  financing  leases,
and the  unearned  income  is  recognized  each  month as it is  earned so as to
produce a constant periodic rate of return on the unrecovered investment.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

                          December 1997, 1998 and 1999


NOTE A--SIGNIFICANT ACCOUNTING POLICIES (Continued)

Loan origination fees and certain direct  origination and acquisition  costs are
capitalized  and recognized as an adjustment of the yield on the related loan or
lease.  Amortization  is  discontinued  when  the loan or  lease  is  placed  on
nonaccrual status.

Credit card origination costs are deferred and netted against the related credit
card fee, if any, and the net amount amortized on a straight-line basis over the
initial  privilege  period.  Fees  received  and  marketing  costs  incurred  in
connection with  unsuccessful  efforts to create credit card  relationships  are
recorded as revenue and expense when the refundable period expired. Amounts paid
to third-party  direct marketing  specialists  related to successful  efforts to
create credit card  relationships  are deferred and netted against  related fees
and all other  amounts are recorded as expenses in the period the services  were
performed.  Annual  service fees are deferred and amortized over the credit card
privilege period.

Allowance  for Loan and Lease  Losses:  The  allowance is  maintained at a level
which,  in the opinion of  management,  is adequate  to absorb  probable  losses
inherent in the loan,  including credit card receivables,  and lease portfolios.
Management  determines  the  adequacy  of the  allowance  based upon  reviews of
individual loans, recent loss experience,  current economic conditions, the risk
characteristics  of the  various  categories  of  loans  and  leases  and  other
pertinent factors. The allowance is based on estimates,  and ultimate losses may
vary from the current  estimates.  These  estimates  are  evaluated on a regular
basis and, as adjustments become necessary, they are reported in earnings in the
periods in which they become known.  Loans and leases deemed  uncollectible  are
charged to the allowance.  Credit card  receivables are charged to the allowance
when they  become 120 days past due.  Provisions  for losses and  recoveries  on
loans and leases previously charged off are added to the allowance.

Commercial  loans are  considered  impaired,  based on current  information  and
events,  if it is probable  that Bancorp will be unable to collect the scheduled
payments of principal or interest when due according to the contractual terms of
the loan agreement.  Allowances on impaired loans are  established  based on the
present value of expected  future cash flows  discounted at the loans  effective
interest  rate or for  collateral-dependent  loans,  on the  fair  value  of the
collateral. Cash receipts on impaired loans are used to reduce principal.

Income  Recognition  on Impaired  and  Nonaccrual  Loans and  Leases:  Loans and
leases,  including  impaired  loans and leases,  are classified as nonaccrual if
collection  of principal or interest is considered  doubtful,  generally if they
are past due as to maturity or payment of  principal or interest for a period of
more than 90 days,  unless  such loans and leases  are  well-secured  and in the
process  of  collection.  If a loan or lease or a portion  of a loan or lease is
classified  as  doubtful  or is  partially  charged  off,  the  loan or lease is
classified as nonaccrual. Loans that are on a current payment status or past due
less than 90 days may also be  classified  as nonaccrual if repayment in full of
principal and/or interest is in doubt.

Loans and leases  may be  returned  to accrual  status  when all  principal  and
interest amounts contractually due (including arrearages) are reasonably assured
of  repayment  within an  acceptable  period of time,  and there is a  sustained
period  of  repayment  performance  by the  borrower,  in  accordance  with  the
contractual terms of interest and principal.

While a loan or lease is classified as nonaccrual and the future  collectibility
of the recorded  balance is doubtful,  collections of interest and principal are
generally  applied as a  reduction  to  principal  outstanding.  When the future
collectibility  of the  recorded  balance is  expected,  interest  income may be
recognized on a cash basis.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

                          December 1997, 1998 and 1999


NOTE A--SIGNIFICANT ACCOUNTING POLICIES (Continued)

In the case where a  nonaccrual  loan or lease had been  partially  charged off,
recognition of interest on a cash basis is limited to that which would have been
recognized  on the  recorded  balance at the  contractual  interest  rate.  Cash
interest  receipts in excess of that amount are  recorded as  recoveries  to the
allowance  for loan and lease  losses  until prior  charge- offs have been fully
recovered.

Premises  and  Equipment:  Premises  and  equipment  are  stated  at cost,  less
accumulated  depreciation.  The  provision for  depreciation  is computed by the
straight-line  method over the estimated useful lives of the related assets. The
useful lives of buildings and improvements are estimated to be fifteen to thirty
years. The useful lives of furniture,  fixture and equipment are estimated to be
three to ten years.  Leasehold  improvements  are amortized over the life of the
related lease, or the life of the asset,  whichever is shorter.  When assets are
sold or otherwise disposed of, the cost and related accumulated depreciation and
amortization  are removed from the accounts,  and any resulting  gain or loss is
recognized  in income for the  period.  The cost of  maintenance  and repairs is
charged to expense as incurred.

Foreclosed Real Estate: Foreclosed real estate includes both formally foreclosed
property  and  in-substance   foreclosed   property.   In-substance   foreclosed
properties are those properties for which Bancorp has taken physical possession,
regardless of whether formal  foreclosure  proceedings  have taken place. At the
time of  foreclosure,  foreclosed  real  estate is  recorded at the lower of the
carrying  amount or fair value less cost to sell,  which becomes the  property's
new  basis.  Any  write-downs  based  on the  asset's  fair  value  at  date  of
acquisition  are charged to the  allowance for loan losses.  After  foreclosure,
valuations  are  periodically  performed  by  management  and the real estate is
carried at the lower of their new cost basis or fair value minus estimated costs
to sell. Revenue and expenses from operations and subsequent  adjustments to the
carrying amount of the property are included in income (loss) on foreclosed real
estate.

Intangible   Assets:   The  premiums   paid  to  acquire  the  deposits  of  the
McKinleyville, Arcata, Weaverville, Willow Creek, Loleta, Garberville, Ukiah and
Eureka (Burre Center) branches were allocated to core deposit  intangibles based
on the results of valuation studies performed to determine the fair value of the
deposit base acquired.  Core deposit  intangibles  are being  amortized over the
estimated remaining life of the related deposits of 8 to 10 years.

Investment in Leasing Company:  Humboldt Bank, along with another bank, formed a
California  corporation,  Bancorp  Financial  Services,  Inc. for the purpose of
operating  an  equipment  leasing  company.   In  January  1997,  Humboldt  Bank
contributed  capital totaling $2,000,000 for a 50% interest in this corporation.
The  investment  is accounted  for using the equity  method.  During 1998,  this
investment was transferred to the Bancorp.

Investments in Limited Partnerships: Bancorp owns approximately 99% interests in
two limited  partnerships  that own and  operate  affordable  housing  projects.
Investment in these projects  serves as an element of Bancorp's  compliance with
the Community  Reinvestment Act and Bancorp receives tax benefits in the form of
deductions for operating losses and tax credits.  The tax credits may be used to
reduce taxes currently payable or may be carried back one year or forward twenty
years to recapture or reduce taxes. Bancorp uses the equity method of accounting
for the  partnerships'  operating  results and tax  credits are  recorded in the
years they became available to reduce income taxes.

Income Taxes:  Provisions for income taxes are based on amounts  reported in the
statements of operations (after exclusion of non-taxable income such as interest
on state and  municipal  loans and  securities)  and include  deferred  taxes on
temporary  differences  in the  recognition  of income and  expense  for tax and
financial statement purposes.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

                          December 1997, 1998 and 1999


NOTE A--SIGNIFICANT ACCOUNTING POLICIES (Continued)

Deferred taxes are computed using the asset and liability  method.  Deferred tax
assets  and  liabilities   are  recognized  for  the  future  tax   consequences
attributable to differences  between the financial statement carrying amounts of
assets and liabilities and their  respective tax bases.  Deferred tax assets and
liabilities  are measured  using enacted tax rates  expected to apply to taxable
income in the years in which  those  temporary  differences  are  expected to be
recovered  or settled.  The effect on deferred tax assets and  liabilities  of a
change in tax rates is  recognized  in income in the period  that  includes  the
enactment  date.  Deferred tax assets are recognized  for  deductible  temporary
differences  and tax credit  carryforwards,  and then a valuation  allowance  is
established  to reduce that  deferred  tax asset if it is "more likely than not"
that the related tax benefits will not be realized.

Advertising:  Advertising costs are charged to operations in the year incurred.

Net Income Per Share: Net income per share is computed by dividing net income by
the weighted  average  number of common  shares  outstanding  during the period,
after giving  retroactive  effect to stock dividends and splits.  Net income per
share---assuming  dilution  is computed  similar to net income per share  except
that the  denominator  is increased to include the number of  additional  common
shares that would have been outstanding if the dilutive  potential common shares
had been issued.  Included in the  denominator  is the dilutive  effect of stock
options computed under the treasury method.

Off-Balance-Sheet  Financial  Instruments:  In the  ordinary  course of business
Bancorp has entered into off-balance- sheet financial instruments  consisting of
commitments to extend credit,  commitments  under credit card  arrangements  and
standby  letters of credit.  Such  financial  instruments  are  recorded  in the
financial statements when they become payable.

Cash and Cash  Equivalents:  For the purpose of presentation in the Statement of
Cash Flows,  cash and cash  equivalents are defined as those amounts included in
the balance sheet caption "Cash and due from banks."

Unaudited  Interim  Financial Data: The interim  financial  statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information.  Accordingly,  they do not include all of the information
and footnotes required by generally accepted accounting  principles for complete
financial  statements.  In the opinion of management all adjustments,  including
normal  recurring  accruals  necessary  for  fair  presentation  of  results  of
operations for the interim periods included herein,  have been made. The results
of  operations  for the six months  ended  June 30,  2000,  are not  necessarily
indicative of results to be anticipated for the year ending December 31, 2000.

Recently  Issued  Accounting  Standards:  In June 1998,  Statement  of Financial
Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities"  (Statement  No. 133),  was issued.  Statement  No. 133  establishes
accounting and reporting standards for derivative instruments, including certain
derivative instruments embedded in other contracts,  by requiring that an entity
recognize  those items as assets or  liabilities  in the  statement of financial
position and measure them at fair value.  Statement  No. 137,  issued June 1999,
defers the effective date of Statement No. 133 to all fiscal  quarters of fiscal
years beginning after June 15, 2000. The Bancorp does not expect the adoption of
this Statement to have a material impact on its financial position or results of
operations.

NOTE D--LOANS AND LEASES, NET (Continued)

At December 31, 1998, the recorded  investment in loans for which impairment had
been  recognized in accordance with Statement No. 114 totaled  $338,000,  with a
corresponding  valuation  allowance  of  $126,000.  At December  31,  1999,  the
recorded  investment in loans for which  impairment had been recognized  totaled
$849,000,  with a corresponding  valuation allowance of $114,000.  For the years
ended  December 31, 1997,  1998 and 1999,  the average  recorded  investment  in
impaired loans was approximately $156,000, $515,000 and $892,000,  respectively.
In 1997 and  1999,  Bancorp  recognized  $5,000  and  $3,000,  respectively,  of
interest  on  impaired  loans  (during  the  portion  of the year that they were
impaired),  all of which was  recognized  on the cash  basis.  In 1998,  Bancorp
recognized $41,000 of interest on impaired loans (during the portion of the year
that they were  impaired),  of which  $21,000 was related to impaired  loans for
which interest was recognized on the cash basis.

In addition,  at December 31, 1997 and 1998,  Bancorp had other nonaccrual loans
of  approximately  $97,000  and  $246,000  for  which  impairment  had not  been
recognized.  If  interest  on these loans had been  recognized  at the  original
interest  rates,  interest income would have increased  approximately  $5,000 in
1997,  $16,000 in 1998 and $1,000 in 1999.  Bancorp has no  commitments  to loan
additional funds to the borrowers of impaired or nonaccrual loans.

NOTE M--INCOME TAXES (Continued)

Amounts  presented for the tax effects of temporary  differences  are based upon
estimates and  assumptions and could vary from amounts  ultimately  reflected on
Bancorp's  tax returns.  Accordingly,  the variances  from amounts  reported for
prior  years are  primarily  the  result of  adjustments  to  conform to the tax
returns as filed. A valuation  allowance has been established to reduce deferred
tax assets to the amount that is more likely than not to be realized.

Income taxes  (payable)  receivable were $(141,000) and $398,000 at December 31,
1998 and 1999,  respectively.  The income tax expense  (benefit)  related to net
investment  securities  gains was  $42,000 and  $(97,000)  during 1997 and 1999,
respectively. There were no net investment gains during 1998.

of common  stock at $13.52 per share and $14.32  per share,  respectively,  were
outstanding  at December  31, 1999 but were not included in the  computation  of
diluted EPS because the  options'  exercise  price was greater  than the average

NOTE O--BENEFIT PLANS

Retirement  Plan:  Humboldt  Bank has a  defined  contribution  retirement  plan
covering  substantially  all  of  the  Bank's  and  Bancorp's  employees.   Bank
contributions  to the plan are made at the  discretion of the Board of Directors
in an amount  not to exceed  the  maximum  amount  deductible  under the  profit
sharing plan rules of the Internal Revenue Service.  Employees may elect to have
a portion of their  compensation  contributed to the plan in conformity with the
requirements  of Section  401(k) of the  Internal  Revenue  Code.  Salaries  and
employee  benefits expense  includes Bank  contributions to the plan of $134,000
during 1997, $189,000 during 1998 and $223,000 during 1999.

Director Fee Plan:  The Bancorp has adopted the Humboldt  Bank Director Fee Plan
(the "Fee Plan"). The Fee Plan permits each Bancorp director to elect to receive
his/her  director's  fees in the  form  of  Bancorp  common  stock,  cash,  or a
combination  of Bancorp common stock and cash, and to elect to defer the receipt
of any of the foregoing until the end of his/her term as a Bancorp director.  If
deferral is elected,  the amount of the director's  fees shall be credited to an
account on behalf of the director,  however,  such crediting shall  constitute a
mere promise on the part of the Bancorp to pay/distribute  on this account.  The
account is otherwise  unsecured,  unfunded and subject to the general  claims of
creditors of Humboldt  Bank and Bancorp.  The Fee Plan provides for the issuance
of up to 40,000 shares of Bancorp common stock. The amount of such fees deferred
in 1997, 1998 and 1999 totaled $43,000,  $58,000 and $86,000,  respectively.  At
December  31,  1998 and 1999,  the  liability  for  amounts  due under this plan
totaled $110,000 and $196,000,  respectively, or approximately 13,079 and 20,083
shares of stock.

Employee Stock Bonus Plan:  Humboldt Bank has an Employee Stock Bonus Plan which
is funded annually at the sole  discretion of the Board of Directors.  Funds are
invested in Bancorp  stock,  when  available,  and is  purchased  at the current
market price on behalf of all  employees  except the  executive  officers of the
Bancorp.  The compensation  cost recognized for 1997, 1998 and 1999 was $20,000,
$20,000 and $20,000,  respectively.  In addition,  $100,000 was transferred from
the profit sharing plan into this Plan.


NOTE P--STOCK OPTION PLAN

The Bancorp has a  stock-based  compensation  plan  consisting  of a fixed stock
option plan which is described below. The Bancorp applies Accounting  Principles
Board Opinion No. 25 and related  Interpretations  in  accounting  for its plan.
Accordingly, no compensation cost has been recognized for its stock option plan.
Had compensation  cost for the Bancorp's stock option plan been determined based
on the fair value at the grant dates for awards under this plan  consistent with
the method of SFAS No. 123,  the  Bancorp's  net income and net income per share
would have been adjusted to the pro forma amounts  indicated  below  (dollars in
thousands):

NOTE P--STOCK OPTION PLAN (Continued)

The Bancorp has a stock option plan under which incentive and nonstatutory stock
options,  as defined under the Internal  Revenue Code,  may be granted.  Options
representing  456,255  shares of the  Bancorp's no par value common stock may be
granted under the plan by the Board of Directors to directors, officers and key,
full-time  employees at an exercise price not less than the fair market value of
the shares on the date of grant.  In addition,  671,762  options are outstanding
that were  granted by  Humboldt  Bank  prior to the  formation  of the  Bancorp.

are subject to a graded  vesting  schedule of 33% per year for  incentive  stock
options. Nonstatutory stock options vest immediately.

salary  continuation and deferred  compensation plans for certain key employees.
The policies provide  protection  against the adverse financial effects from the
death of a key employee and provide income to offset  expenses  associated  with
the plans.  The specified  employees  are insured  under the  policies,  but the
Bancorp is the owner and  beneficiary.  At December 31, 1998 and 1999,  the cash
surrender  value  of  these  policies  totaled   approximately   $4,943,000  and
$5,157,000, respectively.

The plans are  unfunded and provide for Bancorp to pay the  employees  specified
amounts for specified  periods after retirement and allow the employees to defer
a portion of current  compensation  in exchange for the Bancorp's  commitment to
pay a  deferred  benefit  at  retirement.  If death  occurs  prior to or  during
retirement,  Bancorp will pay the employee's  beneficiary or estate the benefits
set forth in the plans.

At December 31, 1998 and 1999,  liabilities  recorded for the estimated  present
value of future salary continuation and deferred  compensation  benefits totaled
approximately  $2,038,000  and  $2,716,000,  respectively.  Salary  continuation
benefits  may be paid if  termination  is  without  cause or due to a change  in
control of Bancorp.  Otherwise no benefits are paid upon  termination.  Deferred
compensation  is vested  as to the  amounts  deferred.  In the event of death or
under certain other circumstances, Bancorp is contingently liable to make future
payments  greater  than the amounts  recorded as  liabilities.  Based on present
circumstances,  Bancorp  does not  consider it probable  that such a  contingent
liability will be incurred or that in the event of death, such a liability would
be material after consideration of life insurance benefits.

Lease  Commitments:  Bancorp  leases eight sites under  noncancelable  operating
leases  expiring in May 2000,  September  2000,  October  2000,  November  2000,
February 2006,  September  2007,  October 2008 and June 2009. The lease expiring
May 2000 includes an option to renew for two additional  five-year  terms,  with
the monthly  rental being  adjusted to the fair market rental  value.  The lease
expiring  November 2000 includes an option to extend the lease for an additional
term of one year.  The lease  expiring in February 2006 requires  adjustments to
the base rent after two years for changing  price indices with a maximum  annual
increase  of five  percent and  includes an option to renew for two  consecutive
five-year  terms.  The  lease  expiring  September  2007  is  renewable  for two
consecutive five-year periods and requires adjustment every September 1 based on
changing  price  indices  but not less  than 2% nor more  than  10%.  The  lease
expiring  October  2008  requires  annual  adjustments  to the base  rent  every
November 3 of the greater of 2% or the percentage increase in the Consumer Price
Index  and  includes  an  option  to  extend  the term of the  lease  for  three
consecutive  five-year  terms.  The lease expiring June 2009 requires  scheduled
adjustments to the base rent every two years and includes an option to renew for
two consecutive five-year terms.

As of December 31, 1999,  future  minimum  lease  payments  under  noncancelable
operating leases are as follows (dollars in thousands):

NOTE R--COMMITMENTS AND CONTINGENT LIABILITIES (Continued)

Rent  expense for the years  ended  December  31,  1997,  1998 and 1999  totaled
$128,000, $269,000 and $401,000, respectively. Sublease rental income was $4,000
in 1997.

Financial   Instruments  with   Off-Balance-Sheet   Risk:   Bancorp's  financial
statements do not reflect various  commitments and contingent  liabilities which
arise in the normal  course of  business  and which  involve  elements of credit
risk,  interest rate risk and liquidity risk.  These  commitments and contingent
liabilities  are  commitments to extend  credit,  credit card  arrangements  and
standby  letters of credit.  A summary of Bancorp's  commitments  and contingent
liabilities at December 31, is as follows (dollar in thousands):

                                                  Contractual Amounts
                                                1998                1999
                                                ----                ----
Commitments to extend credit                 $  42,200            $ 62,256
Credit card arrangements                        12,299               9,256
Standby letters of credit                        5,240               3,951

Commitments to extend credit,  credit card  arrangements  and standby letters of
credit all include  exposure to some credit loss in the event of  nonperformance
of the customer. Bancorp's credit policies and procedures for credit commitments
and financial  guarantees are the same as those for extension of credit that are
recorded on the balance  sheet.  Because these  instruments  have fixed maturity
dates,  and because many of them expire  without  being drawn upon,  they do not
generally present any significant liquidity risk to Bancorp.

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. Bancorp evaluates each customer's credit worthiness on
a case-by-case basis. The amount of collateral obtained,  if deemed necessary by
Bancorp 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,   certificates  of  deposits  and
income-producing   commercial  properties.   At  December  31,  1998  and  1999,
approximately  $1,300,000 and $157,000,  respectively,  of Bancorp's undisbursed
credit card commitments were secured by deposit accounts.

Standby  letters  of credit  are  conditional  commitments  issued by Bancorp to
guarantee the performance of a customer to a third party.  Those  guarantees are
primarily  issued to support  public and  private  borrowing  arrangements.  All
letters of credit are short-term  guarantees  with no guarantees  extending more
than two  years.  The  credit  risk  involved  in  issuing  letters of credit is
essentially  the same as that  involved in extending  facilities  to  customers.
Bancorp  holds  assigned  deposit   accounts  as  collateral   supporting  those
commitments for which collateral is deemed  necessary.  The extent of collateral
held for those  commitments  at  December  31, 1998 and 1999 varies from zero to
100%; the average amount  collateralized is approximately 92% in 1998 and 83% in
1999. None of these letters of credit were utilized during 1998 or 1999.

Bancorp has not incurred any losses on its commitments in 1997, 1998 or 1999.

NOTE R--COMMITMENTS AND CONTINGENT LIABILITIES (Continued)

Merchant  Credit  and  Debit  Card  Sales  Processing:   Bancorp  processes  the
settlement of credit and debit card sales for merchants  located  throughout the
continental United States,  Alaska, Hawaii and Puerto Rico. The process involves
collecting funds from the card issuing bank and crediting the merchant  accounts
in  exchange  for a  merchant  discount  and  other  processing  fees.  The more
significant  areas of risk associated  with this process  includes the risk that
funds due from the card issuing  bank will be  uncollectible,  that  significant
fines may be assessed for  violations  of VISA or  MasterCard  rules or that the
merchant  will  be  unable  to  absorb  chargebacks,  deliver  products  due  to
insolvency  or may  commit  fraud.  To protect  Bancorp  from  losses,  merchant
deposits of  $46,969,000  at December 31, 1998 and  $54,153,000  at December 31,
1999 have been  established by  withholding a percentage of merchant  processing
volume. Bancorp has incurred approximately $18,000 and $127,000 in losses during
1998 and 1999, respectively.  No losses were incurred in 1997. Bancorp processed
approximately  $2.2  billion and $2.9 billion of credit and debit card sales for
merchants  during 1998 and 1999,  respectively.  Bancorp  markets  its  merchant
bankcard services through five independent  service and marketing  organizations
(ISO's).  Those five ISO's represent $2.8 billion of Bancorp's  credit and debit
card sales  during  1999.  In  addition,  the  merchant  bankcard  services  are
regulated  by VISA.  At this time  Bancorp  does not  believe it is in  complete
compliance with the VISA  requirements and is seeking a waiver. If the waiver is
not  obtained,   Bancorp  would  need  to  restructure  its  merchant   bankcard
operations, which would adversely affect Bancorp's revenues for these services.

Legal Proceedings: Bancorp is a party to claims and legal proceedings arising in
the ordinary  course of business.  After taking into  consideration  information
furnished  by legal  counsel to the Bancorp as to the current  status of various
claims and proceedings to which Bancorp is a party, management is of the opinion
that the ultimate aggregate liability represented thereby, if any, will not have
a material adverse effect on the financial  position or results of operations of
the Bancorp.


NOTE S--CONCENTRATIONS OF CREDIT RISK

Most of Bancorp's  business  activity is with customers located within the State
of California,  primarily in Northern  California except for the merchant credit
card debit card sales processing as discussed in Note R. The economy of Humboldt
Bank's primary service area is heavily  dependent on the area's major industries
which are timber, commercial fishing,  agriculture and tourism. General economic
conditions or natural disasters  affecting the primary service area or its major
industries could affect the ability of customers to repay loans and the value of
real property used as collateral.

In  addition  to the  types  of  loans  as set  forth  in  Note D,  Bancorp  has
concentrations in out-of-area  participation loans, motel loans, commercial real
estate and construction  loans. The distribution of commitments to extend credit
approximates  the distribution of loans  outstanding.  Standby letters of credit
were granted primarily to commercial borrowers.  Bancorp, as a matter of policy,
does not extend credit to any single borrower or group of related borrowers on a
secured basis in excess of 25% of its unimpaired capital  (shareholders'  equity
plus the  allowance  for loan and lease  losses)  and on an  unsecured  basis in
excess of 15% of its unimpaired capital.

Bancorp places its cash investments primarily in financial instruments backed by
the U.S.  Government and its agencies or by high quality financial  institutions
or  corporations.  At  December  31,  1998 and 1999,  approximately  9% and 63%,
respectively, of Bancorp's net worth was invested in federal funds sold to a New
York bank. In addition,  at December 31, 1999, Bancorp had deposits in federally
insured banks in excess of federally insured limits by $4,196,000.

NOTE T--REGULATORY MATTERS

Generally, the primary source of cash for the Bancorp will be dividends received
from its  subsidiaries.  Banking  regulations limit the amount of cash dividends
that may be paid  without  prior  approval of Humboldt  Bank and Capitol  Valley
Bank's regulatory  agency.  Cash dividends are limited to the lesser of retained
earnings,  if any, or net income for the last three years,  net of the amount of
any other distributions made to shareholders during such periods. As of December
31, 1999, $6,217,000 was available for cash dividend  distributions for Humboldt
Bank without prior approval.  Capitol Valley Bank could not declare dividends at
December 31, 1999 without prior approval from the regulatory agency.

Bancorp  and  its  subsidiaries  are  subject  to  various   regulatory  capital
requirements  administered  by the  federal  banking  agencies.  Failure to meet
minium  capital  requirements  can  initiate  certain  mandatory---and  possible
additional discretionary---actions by regulators that, if undertaken, could have
a direct material effect on the Bancorp's  financial  statements.  Under capital
adequacy  guidelines and the regulatory  framework for prompt corrective action,
the Bancorp and its  subsidiaries  must meet specific  capital  guidelines  that
involve  quantitative  measures  of  their  assets,  liabilities,   and  certain
off-balance-sheet  items as calculated  under regulatory  accounting  practices.
These  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  Bancorp to maintain  minimum amounts and ratios (set forth in the table
below) of total and Tier I capital  (as  defined  in the  regulations)  to risk-
weighted  assets (as  defined),  and of Tier I capital  (as  defined) to average
assets (as defined).  Management believes, as of December 31, 1999, that Bancorp
meets all capital adequacy requirements to which it is subject.

As of December 31, 1999, the most recent  notification  from the Federal Deposit
Insurance  Corporation  (FDIC)  categorized the Bancorp and its  subsidiaries as
well capitalized under the regulatory framework for prompt corrective action. To
be  categorized  as  well  capitalized   Bancorp  must  maintain  minimum  total
risk-based, Tier I risk-based, Tier I leverage ratios as set forth in the table.
There are no  conditions  or events  since  that  notification  that  management
believes  have  changed  the  institution's   category.   The  Bancorp  and  its
subsidiaries' actual capital amounts and ratios are also presented in the table.

NOTE V--BANCORP ACQUISITION OF SILVERADO MERGER CORPORATION

In September 1999,  Bancorp acquired all of the outstanding  shares of Silverado
Merger  Corporation  for 49,502  shares of Bancorp  restricted  common stock and
warrants to purchase up to 99,000  shares of Bancorp stock for $10.91 per share.
Bancorp has the right to  repurchase  the 49,502 shares of common stock for $.91
each,  and the  warrants  to purchase  up to 99,000  shares of common  stock for
$10.91 per share cannot become  exercisable,  in the event  Capitol  Valley Bank
fails to achieve  certain  business  objectives by December 31, 2001.  Until the
contingencies  related to the issuance of the restricted  stock and warrants are
resolved,  the amount  recorded  for this  transaction  will be a  liability  of
$45,002  and the stock and  warrants  issued  will not be  included in per share
information.  The fair  value as of the  merger  date of the stock and  warrants
issued to the Silverado Merger  Corporation  stockholders will be recorded as an
additional  cost of the  acquisition if all the  requirements of the acquisition
agreement are achieved. Otherwise, the 49,502 shares of restricted stock will be
repurchased  for $.91 per share and the  warrants  will  expire.  As part of the
acquisition  agreement,  some  shareholders  and supporters of Silverado  Merger
Corporation  purchased $1.6 million of Bancorp restricted common stock at $12.00
per share pursuant to a private placement.  Silverado has no operations, and all
of its obligations and liabilities  were  extinguished  prior to consummation of
the  merger.  Therefore,  Silverado's  financial  statements  at the time of the
merger were immaterial.


NOTE W--FAIR VALUES OF FINANCIAL INSTRUMENTS

Statement of Financial  Accounting  Standards  No. 107,  Disclosures  about Fair
Value of Financial  Instruments,  requires  disclosure of fair value information
about financial instruments,  whether or not recognized in the balance sheet. In
cases where quoted  market  prices are not  available,  fair values are based on
estimates using present value or other valuation  techniques.  Those  techniques
are significantly  affected by the assumptions used, including the discount rate
and  estimates  of future cash flows.  In that  regard,  the derived  fair value
estimates cannot be  substantiated by comparison to independent  markets and, in
many cases,  could not be realized in immediate  settlement of the  instruments.
Statement No. 107 excludes  certain  financial  instruments and all nonfinancial
instruments from its disclosure  requirements.  Accordingly,  the aggregate fair
value amounts presented do not represent the underling value of the Bancorp as a
whole.

</TABLE>


The carrying  amounts in the  preceding  table are included in the balance sheet
under the applicable captions.

The following methods and assumptions were used by the Bancorp in estimating its
fair value disclosures for financial instruments:

Cash and due from  banks,  interest-bearing  deposits in other banks and federal
funds sold: The carrying amount is a reasonable estimate of fair value.

Investment securities: Fair values for investment securities are based on quoted
market prices, where available. If quoted market prices are not available,  fair
values are based on quoted market prices of comparable instruments. The carrying
amount of accrued interest receivable approximates its fair value.

Loans and leases  held for sale:  Fair values for loans and leases held for sale
are based on quoted  market  prices or dealer  quotes.  If a quoted price is not
available,  fair value is estimated using quoted market prices for similar loans
or leases.

Loans and lease financing receivables, net: For variable-rate loans that reprice
frequently  and  fixed  rate  loans  that  mature  in the near  future,  with no
significant  change in credit risk,  fair values are based on carrying  amounts.
The fair values for other fixed rate loans are estimated  using  discounted cash
flow analysis,  based on interest rates  currently  being offered for loans with
similar terms to borrowers of similar credit quality.  Bancorp's lease portfolio
has  relatively  high fixed  rates that  usually do not  fluctuate  with  market
changes and, therefore, the carrying amount is a reasonable estimate of the fair
value. Loan and lease fair value estimates  include  judgments  regarding future
expected  loss  experience  and risk  characteristics  and are  adjusted for the
allowance for loan and lease  losses.  The carrying  amount of accrued  interest
receivable approximates its fair value.

NOTE W--FAIR VALUES OF FINANCIAL INSTRUMENTS (Continued)

Cash surrender value of life insurance:  The carrying  amount  approximates  its
fair value.

Deposits:   The  fair  values   disclosed  for  demand  deposits  (for  example,
interest-bearing  checking  accounts and passbook  accounts) are, by definition,
equal to the amount  payable  on demand at the  reporting  date (that is,  their
carrying  amounts).  The fair values for  certificates  of deposit are estimated
using a discounted cash flow  calculation  that applies interest rates currently
being offered on certificates to a schedule of aggregated contractual maturities
on  such  time  deposits.  The  carrying  amount  of  accrued  interest  payable
approximates fair value.

Long-term debt: The fair value of long-term debt is estimated using a discounted
cash flow  calculation  that applies  interest rates  currently being offered on
similar debt instruments.

Off-balance  sheet  instruments:   Off-balance  sheet  commitments   consist  of
commitments to extend credit,  credit card  arrangements  and standby letters of
credit. The contract or notional amounts of Bancorp's financial instruments with
off-balance-sheet  risk are  disclosed in Note R.  Estimating  the fair value of
these   financial   instruments  is  not  considered   practicable  due  to  the
immateriality  of the amounts of fees  collected,  which are used as a basis for
calculating the fair value, on such instruments.


NOTE X--SUBSEQUENT EVENTS

Bancorp has entered into a merger  agreement with Global  Bancorp,  a California
bank holding company that owns Capitol Thrift and Loan Association, a California
industrial loan company with 10 branches located  throughout  California.  Under
the merger  agreement,  Capitol Thrift will become a wholly-owned  subsidiary of
Bancorp.  The  acquisition  is subject to conditions  including  approval by the
shareholders of Global  Bancorp,  regulatory  approval,  and the completion of a
stock  offering.  The estimated  purchase  price of Global Bancorp will be $16.5
million,  $11.8  million of which will be in cash and $4.7 million of which will
be a contingent payment in the form of a promissory note due on January 30, 2002
bearing  interest at 8%, that is contingent on future events and can be adjusted
upward or downward  based on  criteria  set forth in the merger  agreement.  The
merger will be  accounted  for as a purchase.  If either party fails to complete
the acquisition for certain specified  reasons, a termination fee of $250,000 to
$350,000 could be imposed.

In February  2000,  Bancorp  filed a  registration  statement  for the sale of a
minimum of 320,000 shares of common stock at $12.50 per share.  Bancorp  intends
to use the  proceeds  to  assist in the  purchase  of  Global  Bancorp.  Bancorp
incurred  $238,000 of costs  related to the stock  offering  as of December  31,
1999.  These costs are  recorded as an other asset and are expected to be netted
against the proceeds raised upon successful completion of the stock offering. In
addition,  Bancorp  intends to acquire  additional  capital of $5 million by the
issuance of subordinated debentures at an estimated rate of 10.875% per annum.

In 1998,  Bancorp purchased a building and land for approximately  $2.9 million.
Bancorp intends to renovate the property so that all of Bancorp's administrative
offices and  departments  will be centrally  located.  The estimated cost of the
renovation is $3.3 to $3.9  million.  At December 31, 1999,  approximately  $1.1
million  in costs  have been  incurred  for design  work.  Upon its  completion,
Bancorp has an agreement to lease a portion of the facility to a local agency in
exchange for approximately $27,000 per month.

NOTE X--SUBSEQUENT EVENTS (Continued)

On January 11, 2000,  Bancorp's Board of Directors declared a 10% stock dividend
on outstanding common stock to be distributed on February 7, 2000, to holders of
record on January  28,  2000.  As a result of the  dividend,  472,879  shares of
common  stock will be  distributed  and  fractional  shares will be purchased at
$12.727 per share. All per share data and computations  have been  retroactively
adjusted to reflect the stock dividend.


NOTE Y--OPERATING SEGMENTS

Reportable  operating  segments  are  generally  defined  as  components  of  an
enterprise  for  which  discrete  financial  information  is  available,   whose
operating results are regularly reviewed by the  organization's  decision makers
and  whose  revenue  from  external  customers  is 10  percent  or more of total
revenue.  The Bancorp has two reportable segments under this definition,  retail
banking  and  credit  card  operations.  The  retail  banking  segment  provides
traditional banking services such as checking,  savings, IRA and Keogh accounts,
time  certificates  of deposit,  loans,  and lease  financings.  The credit card
segment  processes  the  settlement of credit and debit card sales for merchants
and issues and maintains credit card accounts for its customers.  The accounting
policies  of the  segments  are the same as those  described  in the  summary of
significant  accounting  policies.   Each  segment  receives  an  allocation  of
administrative  expenses.  The Bancorp evaluates  performance based on profit or
loss from operations before income taxes. The Bancorp's  reportable segments are
strategic business units that provide different services that are carried out by
separate  departments.  Included  in the retail  banking  segment  are all other
operations of the Bancorp,  which include an investment in an equipment  leasing
company.

The following table includes  segment  profit,  including  certain  revenues and
expenses, and segment assets (in thousands) of and for the year ended:

June 30, 2000 are not necessarily indicative of the results that may be expected
for the year ended December 31, 2000.

     Tehama Bancorp was incorporated on January 15, 1997 and consumated a merger
with Tehama Bank on June 30, 1997. The consolidated financial statements include
the accounts of the Company and its wholly owned  subsidiary  Tehama Bank, and a
50% interest in Bancorp  Financial  Services,  Inc.  All  material  intercompany
accounts and transactions have been eliminated in consolidation.

Note B  Comprehensive Income

     As  of  January  1,  1998,  the  Company  adopted  Statement  of  Financial
Accounting  Standards No. 130, Reporting  Comprehensive  Income (SFAS 130). This
statement  establishes  standards for the reporting and display of comprehensive
income  and  its  components  in the  financial  statements.  For  the  Company,
comprehensive income includes net income reported on the statement of income and
changes  in the fair value of its  available-for-sale  investments  reported  as
other comprehensive income.

Note C  Earnings per Share

     Basic earnings per share is computed by dividing net income by the weighted
average common shares  outstanding  for the period.  Diluted  earnings per share
reflects the potential  dilution that could occur if options or other  contracts
to issue common stock were  exercised and converted  into common stock.  Diluted
earnings per share is computed by dividing net income by the weighted average of
common shares outstanding including common stock equivalents of options.

Note E  Segment Information

     Operating  segments are  components of an enterprise  about which  separate
financial  information  is  available  that is  evaluated  regularly  by  senior
management. Generally, financial information is reported on the basis that it is
used  internally  for  evaluating  segment  performance  and in deciding  how to
allocate resources to segments.

     The Company has four reportable  segments:  Retail and Commercial  Banking,
Merchant  Card  Processing,  ATM Cash  Services,  and  Bancorp.  The  Retail and
Commercial  Banking  segment  offers a  diverse  range of  traditional  loan and
deposit  products and services to individuals and businesses.  The Merchant Card
Processing  segment is responsible for the processing of third-party credit card
transactions.  The ATM Cash Services  segment is responsible for servicing third
party ATM machines.  The Bancorp  segment  represents the activity at the Bank's
holding company,  which primarily  consists of the Company's share of net income
from its joint venture in a leasing company Bancorp Financial Services.

     The  accounting  policies of the segments  are the same as those  described
Note A.

                          INDEPENDENT AUDITOR'S REPORT



The Board of Directors
   and Shareholders
Tehama Bancorp and Subsidiary

     We have  audited  the  accompanying  consolidated  balance  sheet of Tehama
Bancorp  and  subsidiary  as of  December  31,  1998 and 1999,  and the  related
consolidated  statements  of income,  changes in  shareholders'  equity and cash
flows for each of the three years in the period ended  December 31, 1999.  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  generally  accepted  auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion,  the consolidated  financial  statements  referred to above
present fairly, in all material respects, the consolidated financial position of
Tehama  Bancorp  and  subsidiary  as of  December  31,  1998 and  1999,  and the
consolidated  results of their  operations  and their cash flows for each of the
three years in the period ended December 31, 1999, in conformity  with generally
accepted accounting principles.

                          TEHAMA BANCORP AND SUBSIDIARY

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     General

     Tehama  Bancorp (the  "Company") was  incorporated  on January 15, 1997 and
     subsequently  obtained  approval of the Board of  Governors  of the Federal
     Reserve System to be a bank holding company.  On June 30, 1997, Tehama Bank
     (the  "Bank")  consummated  a merger with Tehama  Bancorp that was effected
     through the exchange of one share of the Company's  stock for each share of
     the Bank's stock.  The Bank is engaged in consumer and commercial  banking,
     offering  products and services to  individuals  and  businesses in a four-
     county region.

     The  accounting  and reporting  policies of the Company and its  subsidiary
     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 1999.

     Principles of Consolidation

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

     The Company's fifty percent investment in Bancorp Financial Services, Inc.,
     a leasing  company,  is accounted  for by the equity  method.  Although the
     Company owns fifty percent of the outstanding stock of the leasing company,
     it does not have the ability to  significantly  influence the financial and
     operating policies of Bancorp Financial Services, Inc.

     Investment Securities

     Investments are classified into one of the following categories:

     o    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.

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

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

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

     Loans Held for Sale

     Loans held for sale consist of mortgage  loans and are carried at the lower
     of cost or market  value.  Market  value is  determined  using the specific
     identification  method as of the balance sheet date.  Unrealized losses and
     realized  gains and losses are  determined  on the specific  identification
     method and are reflected in  non-interest  income or other  expense.  Loans
     held for sale are  included on the  consolidated  balance  sheet in accrued
     interest receivable and other assets.

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

     Loans

     Loans are  stated  at  principal  balances  outstanding,  except  for loans
     transferred  from  loans  held for sale  which are  carried at the lower of
     principal  balance or market  value at the date of  transfer  adjusted  for
     accretion of discounts.  Interest is accrued  daily based upon  outstanding
     loan  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.

     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 balances of deferred fees and
     costs and unearned loan discounts are reported as components of net loans.

     Transfers and Servicing of Loans

     Servicing  rights  acquired  through 1) a purchase or 2) the origination of
     loans which are sold or  securitized  with  servicing  rights  retained are
     recognized  as  separate  assets  or  liabilities.   Servicing   assets  or
     liabilities  are  recorded  at  the  difference   between  the  contractual
     servicing  fees and adequate  compensation  for  performing  the servicing,
     subsequently  amortized in proportion to and over the period of the related
     net  servicing  income or expense.  Servicing  assets and  liabilities  are
     periodically  evaluated for  impairment.  Servicing  assets and liabilities
     were not material for the years ended December 31, 1998 and 1999.

     Servicing  rights on loans  serviced  for others  with  unpaid  balances of
     $14,630,000  were sold in  December  1999.  Loans with  unpaid  balances of
     approximately  $19,509,000 and $2,698,000 were being serviced for others at
     December 31, 1998 and 1999, respectively. A gain of $85,500 is reflected in
     non-interest income.

     Allowance for Loan and Lease Losses

     The allowance for loan and lease losses is maintained to provide for losses
     related to impaired  loans and leases and other losses that can be expected
     to occur  in the  normal  course  of  business.  The  determination  of the
     allowance  is  based  on   estimates   made  by   management,   to  include
     consideration   of  the   character  of  the  loan  and  lease   portfolio,
     specifically identified problem loans and leases, potential losses inherent
     in the  portfolio  taken as a whole and economic  conditions  in the Bank's
     service area.  These estimates are  particularly  susceptible to changes in
     the  economic   environment  and  market   conditions.   The  allowance  is
     established  through a provision for loan and lease losses which is charged
     to expense.

     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,  net of
     estimated  selling  costs,  is charged  against the  allowance for loan and
     lease  losses.  A  valuation  allowance  for losses on other real estate is
     maintained to provide for temporary declines in value.  Subsequent gains or
     losses on sales or  writedowns  resulting  from  permanent  impairment  are
     recorded in other  income or expense as  incurred.  On the  balance  sheet,
     other real  estate is  included in accrued  interest  receivable  and other
     assets.

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

     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 lives of furniture,  fixtures and equipment are
     estimated to be three to ten years.  Leasehold  improvements  are amortized
     over the life of the related lease, or the life of the asset,  whichever is
     shorter.  When  assets  are sold or  otherwise  disposed  of,  the cost and
     related  accumulated  depreciation  and  amortization  are removed from the
     accounts,  and any  resulting  gain or loss is recognized in income for the
     period.  The cost of  maintenance  and  repairs  is  charged  to expense as
     incurred.

     Income Taxes

     Deferred tax assets and liabilities are recognized for the tax consequences
     of temporary  differences  between the financial statement and tax basis of
     existing  assets and  liabilities.  On the balance sheet,  net deferred tax
     assets are included in accrued interest receivable and other assets.

     The  Company  files  its  income  taxes on a  consolidated  basis  with its
     subsidiary. The allocation of income taxes to the subsidiary represents its
     proportionate share of the consolidated provision for income taxes.

     Cash and Cash Equivalents

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

     Earnings Per Share

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

     Merchant Bank Card Processing

     The Bank serves as a merchant processor, under contract with a third party,
     for processing credit card transactions of selected  merchants.  Processing
     fees are recorded as non-interest  income and were based upon a contractual
     percentage of valid credit card  transactions  processed each month through
     February 1999.  Beginning in March 1999, the Bank earns a flat fee based on
     minimum  processing  levels.  Prior to 1999,  selected  direct costs of the
     Bank's merchant card processing  personnel were reimbursed by the program's
     marketing agent. The credit card processing  equipment and related software
     are assets of the third  party and are not  reflected  in the  consolidated
     financial statements.

     Automated Teller Machine Cash Services

     The  Bank  supplies  cash  to  selected  privately-owned  automated  teller
     machines  (ATM's).  Fees are recorded as  non-interest  income based upon a
     contractual percentage of the cash supplied each month.

     Use of Estimates

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

     Stock-Based Compensation

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

     New Financial Accounting Standard

     In June 1998,  the Financial  Accounting  Standards  Board issued SFAS 133,
     Accounting  for  Derivative  Instruments  and Hedging  Activity,  which was
     subsequently  amended by SFAS 137 to delay the effective date to all fiscal
     quarters of fiscal  years  beginning  after June 15, 2000.  This  Statement
     establishes accounting and reporting standards for derivative  instruments,
     including certain derivative  instruments embedded in other contracts,  and
     for hedging activities. It requires that entities recognize all derivatives
     as either  assets or  liabilities  in the balance  sheet and measure  those
     instruments at fair value. Management does not believe that the adoption of
     SFAS 133 will have a  significant  impact  on its  financial  position  and
     results of operations when implemented.

8.   SHORT-TERM BORROWING ARRANGEMENTS

     The Bank has a $7,500,000  unsecured borrowing  arrangement with one of its
     correspondent  banks.  There  were no  borrowings  outstanding  under  this
     arrangement  at December  31,  1998.  At December  31,  1999,  the Bank had
     outstanding  borrowings of $2,100,000 under this arrangement at an interest
     rate of 5.75%.  Interest expense was $9,642 and $15,842 for the years ended
     December 31, 1998 and 1999, respectively.

     At December 31, 1999, the Bank could also borrow up to twenty-five  percent
     of its total assets from the Federal Home Loan Bank,  secured by investment
     securities with amortized costs totaling  $17,483,000 and estimated  market
     values  totaling   $16,421,000.   There  were  no  borrowings   under  this
     arrangement at December 31, 1998 or 1999.

9.   COMMITMENTS AND CONTINGENCIES

     Leases

     The Bank leases  premises  and  equipment  under  non-cancelable  operating
     leases.  These leases expire on various dates through 2008 and have various
     renewal options ranging from five to ten years.

     Future minimum lease payments are as follows:

          Year Ending

     Rental  expense for premises and  equipment  included in occupancy  expense
     totaled approximately  $111,000,  $156,000 and $203,000 for the years ended
     December 31, 1997, 1998 and 1999, respectively.

     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 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. Management uses
     the same credit policies in making  commitments and letters of credit as it
     does for loans included on the balance sheet.

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

                                                    December 31,
                                                1998           1999
                                            ------------   ------------

     Commitments to extend credit           $ 17,847,000   $ 27,109,000
     Letters of credit                      $    140,000   $    285,000

9.   COMMITMENTS AND CONTINGENCIES (Continued)

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

     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. Management evaluates
     each customer's  creditworthiness  on a case-by-case  basis.  The amount of
     collateral obtained, if deemed necessary upon extension of credit, is based
     on management's credit evaluation of the borrower.  Collateral held varies,
     but may include  real estate,  accounts  receivable,  deposit  accounts and
     personal property.

     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, 1999, commercial loan commitments  represent  approximately
     69% of total  commitments  and are  generally  unsecured.  Real estate loan
     commitments represent 18% of total commitments and are generally secured by
     property with a  loan-to-value  ratio not to exceed 80%.  Unsecured  credit
     cards and consumer  lines of credit  represent  the  remaining 13% of total
     commitments.  In  addition,  the  majority of the Bank's  commitments  have
     variable interest rates.

     The Bank's financial  instruments  also include  commitments to sell loans.
     Commitments to sell loans are  agreements to sell to another  party,  loans
     originated by the Bank. The Bank only sells loans to third parties  without
     recourse.  As long as the Bank has fulfilled its  obligations  as stated in
     the sales  commitment on such loans, the Bank is not exposed to credit loss
     if the borrower fails to perform according to the promissory note.

     Significant Concentrations of Credit Risk

     The Bank grants real estate mortgage, real estate construction,  commercial
     and installment  loans to customers  throughout  Tehama,  Butte,  Glenn and
     Shasta counties.

     Although the Bank has a diversified loan portfolio,  a substantial  portion
     of its  portfolio is secured by  commercial  and  residential  real estate.
     Additionally,  automobiles,  trucks  and  recreational  vehicles  secure  a
     substantial portion of the Bank's installment loans. However,  personal and
     business  income  represents the primary source of repayment for a majority
     of these loans.

     Merchant Bank Card Processing

     The Bank has a merchant transaction  servicing agreement for the processing
     of credit card  transactions  with First Data Resources,  Inc. (FDRI).  The
     Bank is contingently liable for undetected fraud on third-party credit card
     transactions  processed under its agreement with FDRI. However, the Bank is
     reimbursed  on a  monthly  basis by the  marketing  agent  of the  program,
     CardService  International,  Inc. (CSI), for losses incurred.  The Bank has
     not  incurred  any  losses to date for  transactions  processed  under this
     program.

     Data Processing

     The Bank has also entered into a data  processing  service  agreement  with
     Bank Processing, Inc. Under this agreement, the Bank's minimum payments are
     as follows:

          Year Ending

9.   COMMITMENTS AND CONTINGENCIES (Continued)

     Correspondent Banking Agreements

     The Bank maintains funds on deposit with other federally  insured financial
     institutions under  correspondent  banking  agreements.  Uninsured deposits
     totaled $10,239,315 at December 31, 1999.

     Contingencies

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

10.  SHAREHOLDERS' EQUITY

     Dividends

     On March 16,  2000,  the Board of Directors  declared a 10% stock  dividend
     payable  May 15,  2000 to  shareholders  of record on April 10,  2000.  The
     dividend  resulted  in a charge  to  retained  earnings  in the  amount  of
     $2,223,728,  which was based on the  estimated  fair value of the Company's
     common  stock.  In  connection  with the 10% stock  dividend,  the  Company
     increased  the number of stock  options under its stock option plans by 10%
     and reduced the exercise  prices  accordingly.  All  references to weighted
     average shares outstanding,  per share amounts, option shares, and exercise
     prices included in the accompanying  consolidated  financial statements and
     notes reflect the 10% stock dividend and its retroactive effect.

     Upon declaration by the Board of Directors of the Company, all shareholders
     of record will be entitled to receive dividends. The Company's only present
     source of income with which to pay  dividends is  dividends  from the Bank.
     The California  Financial Code restricts the total cash dividend payment of
     any  state  bank at any  time to the  lesser  of (1)  the  Bank's  retained
     earnings or (2) the Bank's net income for its last three fiscal years, less
     distributions  made to shareholders  during the same three-year  period. At
     December 31, 1999, the Bank had $3,243,078 in retained  earnings  available
     for dividend payments to the Company.

     diluted earnings per share computations is as follows:

     The  following  options  were not  included in the  computation  of diluted
     earnings  per share  because  their  exercise  prices were greater than the
     average market prices of the common shares during the same periods: options
     to purchase  37,829 shares of common stock at prices ranging from $15.28 to
     $15.91 outstanding during the second and third quarters of 1998; options to
     purchase  57,508  shares of common  stock at prices  ranging from $12.73 to
     $15.91  outstanding  during the fourth quarter of 1998; options to purchase
     36,850  shares of  common  stock at prices  ranging  from  $12.05 to $15.28
     outstanding  during the first quarter of 1999;  options to purchase  57,844
     shares of common stock at prices ranging from $11.15 to $15.28  outstanding
     during the second quarter of 1999;  and options to purchase  151,894 shares
     of common stock at prices ranging from $10.80 to $15.28  outstanding during
     the third and fourth quarters of 1999.

     Stock Options

     In 1994 and 1999, the Board of Directors established stock option plans for
     which 553,442 shares of common stock are reserved for issuance to employees
     and directors  under  incentive and  nonstatutory  agreements.  The Company
     assumed all obligations  under the 1994 plan as of July 1, 1997 and options
     to purchase  shares of the  Company's  common  stock were  substituted  for
     options to purchase  shares of common stock of the Bank.  The plans require
     that the  option  price may not be less than the fair  market  value of the
     stock at the date the option is granted, and that the stock must be paid in
     full at the time the option is exercised. Options granted generally vest at
     twenty  percent  each year.  The  options  under the plans  expire on dates
     determined by the Board of Directors, but not later than ten years from the
     date of grant.  Outstanding  options  under  the 1994 Plan are  exercisable
     until their expiration date;  however, no new options will be granted under
     this plan.

     The Company has adopted the  disclosure-only  provisions  of  Statement  of
     Financial   Accounting   Standards  No.  123,  Accounting  for  Stock-Based
     Compensation.  Accordingly, no compensation expense has been recognized for
     its stock option plans. Had compensation  cost been determined based on the
     fair value at grant date for  awards in 1999 and 1998  consistent  with the
     provisions  of SFAS No. 123,  the  Company's  net earnings and earnings per
     share would have been reduced to the pro forma amounts indicated below. Pro
     forma  compensation  expense is recognized in the years the options  become
     vested.

10.  SHAREHOLDERS' EQUITY (Continued)

     Common Stock Repurchase Program

     During 1997,  the Board of Directors  authorized  the  repurchase  of up to
     $500,000 of the Company's common stock.  Repurchases will generally be made
     at market prices.  Shares were  purchased for $260,559 and $236,647  during
     the years ended December 31, 1998 and 1999, respectively.

     Regulatory Capital

     The  Company  and the  Bank  are  subject  to  certain  regulatory  capital
     requirements  administered by the Board of Governors of the Federal Reserve
     System  (FRB).  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 Company and 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 Company and the Bank meet all their  capital
     adequacy requirements as of December 31, 1999.

     In  addition,  the most recent  notification  from the  Federal  Depository
     Insurance Corporation (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  below.  There are no
     conditions or events since that notification that management  believes have
     changed the Bank's category.

12.  EMPLOYEE BENEFIT PLANS

     Employee Stock Ownership Plan

     In 1987, the Bank adopted an employee stock  ownership  plan.  This plan is
     designed to invest primarily in securities of the Company, purchased on the
     open  market.  The  Company's  contributions  to the  plan  are at the sole
     discretion  of the  Board of  Directors.  Contributions  are  limited  on a
     participant-by-participant  basis to the lesser of  $30,000 or  twenty-five
     percent  of the  participant's  compensation  for the plan  year.  Employee
     contributions are not permitted. The Company made contributions of $29,875,
     $39,403 and $38,332 for the years ended  December 31, 1997,  1998 and 1999,
     respectively.

     Profit Sharing Plan

     During 1992,  the Bank adopted the Tehama Bank 401(k) Profit  Sharing Plan.
     The plan is available to all employees of the Bank. The Bank's contribution
     to the plan is  discretionary  and is allocated at  twenty-five  percent of
     each  participant's  annual  contribution.  Aggregate  contributions to the
     profit  sharing  plan  totaled  $30,795,  $38,868 and $54,632 for the years
     ended December 31, 1997, 1998 and 1999, respectively.

     Salary Continuation Plans

     The Bank has salary  continuation  plans for key  executives.  Under  these
     plans, the Bank is obligated to provide the executives, or their designated
     beneficiaries,  with annual benefits for fifteen years after  retirement or
     death. These benefits are substantially equivalent to those available under
     insurance policies purchased by the Bank on the lives of the executives. In
     addition,  the estimated present value of these future benefits are accrued
     over the  period  from the  effective  date of the plans  until each of the
     executive's  expected  retirement date. The expense  recognized under these
     plans  for the  years  ended  December  31,  1997,  1998 and  1999  totaled
     $136,293, $114,620 and $163,207, respectively.

     Under these  plans,  the Bank  invested in single  premium  life  insurance
     policies with cash surrender  values totaling  $2,946,792 and $3,477,561 at
     December  31,  1998 and 1999,  respectively.  On the  consolidated  balance
     sheet,  the cash surrender value of life insurance  policies is included in
     accrued interest receivable and other assets.

13.  RELATED PARTY TRANSACTIONS

     During the  normal  course of  business,  the  Company  and Bank enter into
     transactions  with related  parties,  including  Directors and  affiliates.
     These  transactions are on  substantially  the same terms and conditions as
     those  prevailing for comparable  transactions  with unrelated  parties and
     include  borrowings  from the Bank, the purchase of casualty  insurance and
     advertising  through Directors and the leasing of the Red Bluff branch from
     a Director.

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

     During  1997  and  1998,  the  Bank  purchased  a  total  of  approximately
     $8,802,000  in leases from  Bancorp  Financial  Services,  Inc. at the same
     price  offered  to  other  lease  purchasers.  Leases  were  evaluated  for
     creditworthiness   in  accordance  with  the  Bank's  normal   underwriting
     procedures.  At December 31, 1998 and 1999, the remaining balances on these
     leases  totaled  $8,427,000  and  $5,050,000,  respectively.  There were no
     leases purchased during 1999.

14.  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 (loss)
     are presented in the Statement of Changes in Shareholders' Equity.

     For the  years  ended  December  31,  1997,  1998 and  1999,  the Bank held
     securities  classified as available-for- sale which had unrealized (losses)
     gains as follows:

15.  DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

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

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

     The following  methods and assumptions  were used by management to estimate
     the fair value of its financial instruments at December 31, 1998 and 1999:

     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,  fair  values are based on  carrying  values.  Fair
     values of loans held for sale are estimated  using quoted market prices for
     similar loans.  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.

     Life insurance  policies:  The fair values of life  insurance  policies are
     based on current cash  surrender  values at each reporting date as provided
     by the insurers.

     Deposits: The fair values for demand deposits are, by definition,  equal to
     the amount payable on demand at each  reporting  date  represented by their
     carrying  amount.  Fair values for fixed-rate  certificates  of deposit are
     estimated  using a discounted cash flow analysis 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.

     Short-term borrowings: Short-term borrowings were originated near year end.
     The carrying amount is estimated to be fair value.

     Treasury tax and loan  agreement:  For the Treasury Tax and Loan Agreement,
     which is included in accrued interest payable and other  liabilities on the
     consolidated  balance  sheet,  the carrying  amount is estimated to be fair
     value.

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

17.  SEGMENT INFORMATION

     Operating  segments are  components of an enterprise  about which  separate
     financial  information is available  that is evaluated  regularly by senior
     management.  Generally, financial information is reported on the basis that
     it is used  internally for evaluating  segment  performance and in deciding
     how to allocate resources to segments.

     The Company has two reportable segments:  Retail and Commercial Banking and
     Merchant Card Processing.  The Retail and Commercial Banking segment offers
     a diverse range of  traditional  loan and deposit  products and services to
     individuals  and  businesses.  The  Merchant  Card  Processing  segment  is
     responsible  for the  processing of third-party  credit card  transactions.
     Results of operations from segments below the  quantitative  thresholds are
     attributable  to two  operating  segments of the  Company.  Those  segments
     include ATM Cash Services and Bancorp, the Bank's holding company.  Neither
     of  those  segments  has ever met any of the  quantitative  thresholds  for
     determining reportable segments.

     The accounting  policies of the segments are the same as those described in
     the Summary of Significant Accounting Policies.

     The following table includes selected  financial  information for the years
     ended December 31, 1997, 1998 and 1999 for each business segment:

Tehama Bank shall total 16 directors  with 14 existing  directors of Tehama Bank
and two persons to be selected by Humboldt.

     Section 2.10 Management of Humboldt and Tehama Bank following the Effective

               ARTICLE 3. REPRESENTATIONS AND WARRANTIES OF TEHAMA

     Tehama represents and warrants to Humboldt as follows:

     Section 3.1  Organization;  Corporate  Power;  Etc.  Tehama is a California
corporation duly organized, validly existing and in good standing under the laws
of the State of California and has all requisite  corporate  power and authority
to own, lease and operate its properties and assets and to carry on its business
substantially as it is being conducted on the date of this Agreement.  Tehama is
a bank holding company registered under the BHCA. Each of Tehama's  Subsidiaries
has all requisite  corporate  power and authority to own,  lease and operate its
properties and to carry on its business  substantially  as it is being conducted
on the date of this  Agreement,  except  where the failure to have such power or
authority would not have a Material Adverse Effect on Tehama taken as a whole or
the  ability  of Tehama to  consummate  the  transactions  contemplated  by this
Agreement.  Tehama has all requisite corporate power and authority to enter into
this Agreement  and,  subject to obtaining all requisite  Regulatory  Approvals,

<PAGE>A-11

Tehama will have the  requisite  corporate  power and  authority  to perform its
respective  obligations  hereunder  with  respect  to  the  consummation  of the
transactions contemplated hereby. Tehama is the sole shareholder of Tehama Bank.
Tehama Bank is a California  state-chartered banking institution duly organized,
validly  existing and in good standing under the laws of the State of California
and has all requisite  corporate  power and authority to own,  lease and operate
its  properties and assets and to carry on its business  substantially  as it is
being conducted on the date of this Agreement.  Tehama Bank is authorized by the
CDFI to  conduct  a general  banking  business.  Tehama  Bank is a member of the
Federal  Reserve  System.  Tehama Bank's deposits are insured by the FDIC in the
manner  and to the full  extent  provided  by law.  Tehama  Bank  maintains  and
operates  branch offices only in the State of  California.  Neither the scope of
business or Tehama, or any Subsidiary of Tehama,  including Tehama Bank, nor the
location of any of their respective  properties,  requires that Tehama or any of
its respective  Subsidiaries be licensed or qualified to conduct business in any
jurisdiction  other  than the state of  California,  where the  failure to be so
licensed or qualified would,  individually or in the aggregate,  have a Material
Adverse Effect on Tehama taken as a whole.

     Section 3.2  Licenses and  Permits.  Except as  disclosed on Schedule  3.2,
Tehama  and  its  Subsidiaries   have  all  material   licenses,   certificates,
franchises,  rights and  permits  that are  necessary  for the  conduct of their
respective  businesses,  and such licenses are in full force and effect,  except
for any failure to be in full force and effect that would not,  individually  or
in the aggregate,  have a Material Adverse Effect on Tehama or on the ability of
Tehama to  consummate  the  transactions  contemplated  by this  Agreement.  The
properties,  assets,  operations  and  businesses  of  Tehama,  and those of its
Subsidiaries, including Tehama Bank, are and have been maintained and conducted,
in  all  material  respects,   in  compliance  with  all  applicable   licenses,
certificates, franchises, rights and permits.

     Section 3.3 Subsidiaries. Other than as set forth on Schedule 3.3, there is
no corporation, partnership, joint venture or other entity in which Tehama owns,
directly or  indirectly  (except as pledgee  pursuant to loans or stock or other
interest held as the result of or in lieu of  foreclosure  pursuant to pledge or
other security arrangement) any equity or other voting interest or position.

     Section 3.4 Authorization of Agreement; No Conflicts.

        3.4.1  The  execution  and  delivery  of  this  Agreement and the Merger
Agreement  by Tehama,  and the  consummation  of the  transactions  contemplated
hereby and thereby,  have been duly authorized by all necessary corporate action
on the part of Tehama,  subject  only to the  approval  of this  Agreement,  the
Merger  Agreement and the Merger by Tehama's  shareholders.  This  Agreement has
been duly  executed and delivered by Tehama and  constitutes a legal,  valid and
binding obligation of Tehama,  enforceable in accordance with its terms,  except
as  the  enforceability  thereof  may  be  limited  by  bankruptcy,  insolvency,
moratorium or other similar laws affecting the rights of creditors generally and
by general equitable principles.  The Merger Agreement,  upon the receipt of all
Requisite  Regulatory  Approvals and the due execution and filing of such Merger
Agreement  in  accordance  with  the  applicable  provisions  of the  California
Corporations  Code,  will  constitute a legal,  valid and binding  obligation of
Tehama,  enforceable in accordance with its terms,  except as the enforceability
thereof may be limited by  bankruptcy,  insolvency,  moratorium or other similar
laws  affecting  the rights of  creditors  generally  and by  general  equitable
principles.

        3.4.2  Except as disclosed on Schedule 3.4, the  execution  and delivery
of this  Agreement  and  the  Merger  Agreement,  and  the  consummation  of the
transactions contemplated hereby and thereby, do not and will not conflict with,
or result in any  violation of or default or loss of a material  benefit  under,

<PAGE>A-12

any provision of the Articles of  Incorporation  or Bylaws of Tehama,  or except
for the necessity of obtaining Requisite Regulatory Approvals,  and the approval
of  the  shareholders  of  Tehama,  any  material  mortgage,  indenture,  lease,
agreement  or  other  material  instrument  or any  permit,  concession,  grant,
franchise,  license,  judgment,  order, decree, statute, law, ordinance, rule or
regulation  applicable to Tehama or any of its assets or properties,  other than
any such conflict, violation, default or loss which (i) will not have a Material
Adverse Effect on Tehama, or on Humboldt immediately  following  consummation of
the Merger;  or (ii) will be cured or waived  prior to the  Effective  Time.  No
material  consent,   approval,  order  or  authorization  of,  or  registration,
declaration  or filing with, any  Governmental  Entity is required in connection
with the  execution  and delivery of this  Agreement or the Merger  Agreement by
Tehama or the performance by Tehama of its obligations hereunder and thereunder,
except for (a)  filings  required  in order to obtain the  Requisite  Regulatory
Approvals;  (b) the  filing  and  approval  of the  Merger  Agreement  with  the
Secretary of the State of California; and (c) Tax Filings.

     Section 3.5  Capital  Structure.  The  authorized  capital  stock of Tehama
consists of 4,000,0000 shares of Tehama Common Stock, no par value per share and
2,000,000  shares of preferred  stock. On the date of this Agreement,  1,896,140
shares of Tehama  Common Stock were  outstanding,  no shares of preferred  stock
were  outstanding  and 241,627  shares of Tehama  Common Stock were reserved for
issuance  pursuant to  outstanding  Tehama Stock  Options under the Tehama Stock
Option Plans. All outstanding  shares of Tehama Common Stock are validly issued,
fully paid and  nonassessable  and do not possess any preemptive rights and were
not issued in violation of any  preemptive  rights or any similar  rights of any
Person.  Except for the Tehama Stock Options and Tehama's  obligations under the
Shareholder  Protection  Rights  Plan,  both  described  on Schedule 3.5 to this
Agreement,  Tehama  does not have  outstanding  any  options,  warrants,  calls,
rights,  commitments,  securities or agreements of any character to which Tehama
is a party or by which it is bound obligating Tehama to issue,  deliver or sell,
or cause to be issued,  delivered or sold, additional shares of capital stock of
Tehama or  obligating  Tehama to grant,  extend or enter  into any such  option,
warrant, call, right, commitment or agreement.

     Section 3.6 Tehama Filings.

        3.6.1 Since January 1, 1997, Tehama and its Subsidiaries  have filed all
reports, registrations and statements,  together with any amendments required to
be made with  respect  thereto,  that  were  required  to be filed  with (a) the
Federal  Reserve Board or any Federal  Reserve Bank; (b) the CDFI; (c) the FDIC;
(d) the SEC; (e) the California  Department of  Corporations;  and (f) any other
applicable  federal,  state or local governmental or regulatory  authority.  All
such  reports,  registrations  and  filings,  and all  reports  sent to Tehama's
shareholders  during the  three-year  period ended December 31, 1999 (whether or
not filed with any Regulatory  Authority),  are collectively  referred to as the
"Tehama  Filings." Except to the extent  prohibited by law, copies of the Tehama
Filings have been made available to Humboldt.  As of their respective  filing or
mailing dates,  each of the past Tehama Filings (a) was true and complete in all
material respects (or was amended so as to be so promptly following discovery of
any  discrepancy);  and (b)  complied in all material  respects  with all of the
statutes,  rules and regulations  enforced or promulgated by the governmental or
regulatory  authority  with  which it was filed (or was  amended  so as to be so
promptly following  discovery of any such  noncompliance) and none contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated  therein or necessary to make the statements  therein,  in light of
the  circumstances  under  which  they were  made,  not  misleading.  The Tehama
Financial  Statements,  together with the financial  statements contained in the
Tehama  Filings,  have been  prepared in  accordance  with GAAP,  or  applicable
regulatory  accounting  principles,  applied on a  consistent  basis  during the
periods  involved  (except as may be indicated in the notes  thereto) and fairly

<PAGE>A-13

adjustments  normal in nature and amount) the financial position of Tehama as of
the dates thereof and the results of its  operations,  cash flows and changes in
shareholders' equity for the periods then ended.

        3.6.2 Tehama, or Tehama Bank, as the case may be, has filed each report,
schedule and  amendments  to each of the foregoing  since January 1, 1997,  that
Tehama or Tehama Bank was required to file with the Federal  Reserve Board,  the
SEC,  the FDIC,  the  California  Department  of  Corporations  or the CDFI (the
"Tehama  Documents"),  all of which have been made available to Humboldt.  As of
their respective  dates, the Tehama Documents  complied in all material respects
with the  applicable  requirements  of the BHCA,  the Exchange  Act, the Federal
Deposit Insurance Act and the California Financial Code, as the case may be, and
the rules and regulations of the Federal  Reserve Board,  the FDIC, the SEC, the
California Department of Corporations and the CDFI thereunder applicable to such
Tehama  Documents,  and  none  of the  Tehama  Documents  contained  any  untrue
statement of a material  fact or omitted to state a material fact required to be
stated  therein or necessary  to make the  statements  therein,  in light of the
circumstances  under  which  they  were  made,  not  misleading.  The  financial
statements  of Tehama  included  in the Tehama  Filings  comply in all  material
respects  with  applicable  regulatory  accounting  requirements  and  with  the
published rules and regulations of the Federal Reserve Board,  the FDIC, the SEC
or the CDFI (as  applicable)  with respect  thereto,  and have been  prepared in
accordance with GAAP, or applicable regulatory accounting principles, applied on
a consistent  basis during the periods  involved  (except as may be indicated in
the notes thereto or, in the case of the unaudited  statements,  as permitted by
regulations  of the  Federal  Reserve  Board,  the FDIC or the CDFI) and  fairly
present  (subject,  in  the  case  of the  unaudited  statements,  to  recurring
adjustments  normal in nature and amount) the financial position of Tehama as of
the dates thereof and the consolidated  results of its operations and cash flows
or changes in financial position for the periods then ended.

     Section 3.7 Accuracy of Information Supplied.

        3.7.1  No representation or  warranty of Tehama  contained herein or any
statement, schedule, exhibit or certificate given or to be given by or on behalf
of Tehama or any of its  Subsidiaries,  including  Tehama  Bank,  to Humboldt in
connection  herewith and none of the  information  supplied or to be supplied by
Tehama or its Subsidiaries,  including Tehama Bank, to Humboldt hereunder to the
best of Tehama's  Knowledge  contains or will  contain any untrue  statement  of
material fact or omit to state any material  fact required to be stated  therein
or  necessary  in  order  to  make  the  statements  therein,  in  light  of the
circumstances under which they are made, not misleading.

        3.7.2  None of the  information  supplied  or to be  supplied  by Tehama
or relating to Tehama and approved by Tehama  which is included or  incorporated
by reference in (i) the Registration  Statement on Form S-4 to be filed with the
SEC by Humboldt in  connection  with the  issuance of shares of Humboldt  Common
Stock in the Merger  (including the Joint Proxy Statement of Humboldt and Tehama
and the Prospectus of Humboldt ("Joint Proxy Statement/Prospectus") constituting
a part thereof, the "Registration Statement") will, at the time the Registration
Statement  becomes  effective  under the  Securities  Act,  contain  any  untrue
statement  of a material  fact or omit to state a material  fact  required to be
stated  therein or necessary  to make the  statements  therein,  in light of the
circumstances  under which they were made, not misleading;  (ii) the Joint Proxy
Statement/Prospectus  and any amendment or supplement thereto will, at all times
from the date of  mailing  to  shareholders  of Tehama  through  the date of the
meeting of  shareholders  of Tehama to be held in  connection  with the  Merger,
contain any untrue statement of a material fact or omit to state a material fact
required to be stated  therein or necessary to make the statements  therein,  in

<PAGE>A-14

light of the circumstances under which they were made, not misleading; and (iii)
the   applications  and  forms  to  be  filed  with  securities  or  "blue  sky"
authorities,   self  regulatory  authorities,  or  any  Governmental  Entity  in
connection with the Merger,  the issuance of any shares of Humboldt Common Stock
in connection with the Merger,  or any Requisite  Regulatory  Approvals will, at
the  time  filed  or at the time  they  become  effective,  contain  any  untrue
statement of a material  fact or omit to state any material  fact required to be
stated  therein or necessary  to make the  statements  therein,  in light of the
circumstances  under  which  they were made,  not  misleading.  The Joint  Proxy
Statement/Prospectus  (except  for such  portions  thereof  that  relate only to
Humboldt and its  Subsidiaries)  will comply in all material  respects  with the
provisions of the Exchange Act and the rules and regulations thereunder.

        3.7.3  Tehama  has  delivered  or  will  deliver  to Humboldt copies of:
(a) the audited  balance sheets of Tehama Bank as of December 31, 1999, 1998 and
1997, and the related statements of income,  changes in shareholders' equity and
cash  flows for the years  then ended and the  related  notes to such  financial
statements,  all as audited by Perry-Smith LLP,  independent  public accountants
(the "Tehama Financial Statements"), and Tehama will hereafter until the Closing
Date deliver to Humboldt copies of additional financial statements of Tehama and
its Subsidiaries as provided in Sections 5.1.1(iii) and 6.1.11(iii).  The Tehama
Financial  Statements have been prepared (and all of said  additional  financial
statements will be prepared) in accordance  with GAAP, or applicable  regulatory
accounting  principles applied on a consistent basis during the periods involved
(except  as may  be  indicated  in  the  notes  thereto)  consistently  followed
throughout  the  periods  covered by such  statements,  and present  (and,  when
prepared,  will  present)  fairly  the  financial  position  of  Tehama  and its
Subsidiaries,  including  Tehama Bank, as of the respective  dates indicated and
the results of operations, cash flows and changes in shareholders' equity at the
respective  dates  and for the  respective  periods  covered  by such  financial
statements  (subject,  in the case of the  unaudited  statements,  to  recurring
adjustments normal in nature and amount).  In addition,  Tehama has delivered or
made available to Humboldt  copies of all management or other letters  delivered
to Tehama or Tehama Bank by its  independent  accountants in connection with any
of the Tehama  Financial  Statements or by such  accountants  or any  consultant
regarding the internal controls or internal compliance procedures and systems of
Tehama or Tehama  Bank issued at any time since  January 1, 1997,  and will make
available for inspection by Humboldt or its  representatives,  at such times and
places as Humboldt may reasonably  request,  reports and working papers produced
or developed by such accountants or consultants.

     Section  3.8  Compliance  with  Applicable  Laws.  Except as  disclosed  on
Schedule  3.8, to the best of Tehama's  Knowledge the  respective  businesses of
Tehama and its  Subsidiaries  are not being  conducted  in violation of any law,
ordinance or regulation,  except for  violations  which  individually  or in the
aggregate would not have a Material Adverse Effect on Tehama,  or Humboldt at or
following  the  Effective  Time.  Except as set forth in  Schedule  3.8,  to the
Knowledge of Tehama no investigation  or review by any Governmental  Entity with
respect  to  Tehama  or  Tehama  Bank  is  pending  or  threatened,  nor has any
Governmental  Entity  indicated to Tehama or Tehama Bank an intention to conduct
the same.

     Section  3.9  Litigation.  Except  as set  forth in  Schedule  3.9,  to the
Knowledge  of Tehama there is no suit,  action or  proceeding  or  investigation
pending or  threatened  against or affecting  Tehama or any of its  Subsidiaries
which, if adversely  determined,  would have a Material Adverse Effect on Tehama
or its  Subsidiaries;  nor is there any judgment,  decree,  injunction,  rule or
order of any Governmental Entity or arbitrator outstanding against Tehama or any
of its Subsidiaries  that has, or which,  insofar as reasonably can be foreseen,
in the future  would  have,  any such  Material  Adverse  Effect.  Schedule  3.9
contains a true,  correct and complete  list,  including  identification  of the
applicable  insurance  policy  covering such  litigation,   if any,  subject  to

<PAGE>A-15

reservation of rights,  if any, the applicable  deductible and the amount of any
reserve  therefor,  of all  pending  litigation  in which  Tehama  or any of its
Subsidiaries  is a named  party of which  Tehama  has  Knowledge,  and except as
disclosed  on Schedule  3.9,  all of the  litigation  shown on such  Schedule is
adequately covered by insurance in force, except for applicable deductibles,  or
has been  adequately  reserved for in accordance  with Tehama's  prior  business
practices.

Schedule 3.11 contains a list of all policies of insurance and bonds carried and
owned by Tehama or any Subsidiary.  None of Tehama or any of its Subsidiaries is
in  default  under  any such  policy  of  insurance  or bond such that it can be
canceled and all material current claims outstanding  thereunder have been filed
in timely fashion.  Tehama and its Subsidiaries have filed claims with, or given
notice of claim to, their  insurers or bonding  companies in timely fashion with
respect to all material matters and occurrences for which they believe they have
coverage.

its  respective  Subsidiaries  has  good  and  marketable  title  to or a  valid
leasehold  interest in all properties and assets (other than real property which

mortgages,  covenants,  conditions,  restrictions,  easements,  liens,  security
interests, charges, claims, assessments and encumbrances, except for: (a) rights
of lessors,  lessees or sublessees in such matters as are reflected in a written
lease;  (b) encumbrances as set forth in the Tehama  Financial  Statements;  (c)
current Taxes  (including  assessments  collected  with Taxes) not yet due which

interfere  with present use, or the ability of Tehama or its  Subsidiary to sell
or otherwise  dispose of the property subject thereto or affected  thereby;  and
(e) other matters as described in Schedule 3.12.  Materially all such properties

description  of all  real  property  owned or  leased  by  Tehama  or any of its
Subsidiaries, including Other Real Estate Owned ("OREO"). Each of Tehama and its
respective  Subsidiaries  has good and marketable  title to the real  properties
that it owns, as described in such  Schedule,  free and clear of all  mortgages,

<PAGE>A-16

best of Tehama's  Knowledge,  the activities of Tehama and its Subsidiaries with
respect to all real property owned or leased by them for use in connection  with
their  operations  are in all material  respects  permitted  and  authorized  by
applicable zoning laws,  ordinances and regulations and all laws and regulations
of any Governmental Entity. Except as set forth in Schedule 3.13, Tehama and its
Subsidiaries  enjoy quiet possession under all material leases to which they are
the  lessees  and all of such  leases  are valid and in full  force and  effect,
except as the enforceability  thereof may be limited by bankruptcy,  insolvency,
moratorium or other similar laws affecting the rights of creditors generally and
by general  equitable  principles.  Materially all buildings and improvements on
real properties owned or leased by Tehama or any of its Subsidiaries are in good
condition  and  repair,  and  do  not  require  more  than  normal  and  routine
maintenance, to keep them in such condition, normal wear and tear excepted.

purposes)  which  were  required  to be filed by or in respect of Tehama and its
Subsidiaries,  or any of their properties,  income and/or operations on or prior

accurately reflected the material facts regarding the income, business,  assets,

authorities  (as, for example,  under law) or to other Persons (as, for example,
under Tax  allocation  agreements),  with  respect  to all  taxable  periods  or
portions of periods  ending on or before the Closing Date,  all  applicable  tax

authority  arising out of any examination of any of the Returns of Tehama or any
Subsidiaries filed for fiscal years ended on or after December 31, 1995, through

any material deficiency will be assessed.

sufficient  accruals for the payment of all Taxes for the periods covered by the
Tehama Financial Statements and all periods prior thereto.

        3.14.8  IRC  Section  382  Applicability.  None  of Tehama or any of its
Subsidiaries,  including any party joining in any  consolidated  return to which
Tehama is a member,  underwent an  "ownership  change" as defined in IRC Section
382(g)  within the  "testing  period"  (as  defined in IRC  Section  382) ending
immediately  before  the  Effective  Time,  and  not  taking  into  account  any
transactions contemplated by this Agreement.

        3.14.9  Disclosure  Information.  Within  45  days  of  the date of this
Agreement,  Tehama will deliver to Humboldt  Schedule  3.14.9  setting forth the
following  information  with  respect  to  Tehama  and  as of  the  most  recent
practicable  date (as well as on an estimated  pro forma basis as of the Closing
giving effect to the consummation of the transactions  contemplated hereby): (a)
Tehama's  basis in its assets;  (b) the amount of any net  operating  loss,  net
capital loss, unused  investment or other credit,  unused foreign tax, or excess
charitable  contribution allocable to Tehama; and (c) the amount of any deferred
gain or loss  allocable to Tehama and arising out of any  deferred  intercompany
transactions.

        Section 3.15  Performance of  Obligations.  Tehama and its  Subsidiaries
have performed all material obligations required to be performed by them to date
and none of Tehama or any of its Subsidiaries is in material default under or in
breach of any term or provision of any covenant,  contract,  lease, indenture or
any other agreement,  written or oral, to which any is a party, is subject or is
otherwise  bound,  and no event has occurred that,  with the giving of notice or
the passage of time or both,  would  constitute such a default or breach,  where
such  default  or breach or failure  to  perform  would have a Material  Adverse
Effect on Tehama or its  Subsidiaries.  To  Tehama's  Knowledge,  and  except as
disclosed on Schedule  3.15 or in the portion of Schedule  3.16 that  identifies
90-day past due or classified or nonaccrual  loans, no party with whom Tehama or
any of its Subsidiaries  has an agreement that is of material  importance to the
businesses of Tehama or its Subsidiaries is in default thereunder.

        Section  3.16  Loans and  Investments.  Except as set forth on  Schedule
3.16, all loans, leases and other extensions of credit, and guaranties, security
agreements or other agreements supporting any loans or extensions of credit, and
investments  of Tehama or its  Subsidiaries,  including  Tehama  Bank,  are, and
constitute,  in all material respects,  the legal, valid and binding obligations
of the parties  thereto and are  enforceable  against such parties in accordance
with  their  terms, except  as  the  enforceability thereof  may  be  limited by

<PAGE>A-18

applicable  law and  otherwise by  bankruptcy,  insolvency,  moratorium or other
similar  laws  affecting  the  rights  of  creditors  generally  and by  general
equitable principles. Except as described on Schedule 3.16, as of July 31, 2000,
no loans or investments held by Tehama or any Subsidiary,  including Tehama Bank
are: (i) more than ninety days past due with respect to any scheduled payment of
principal or interest,  other than loans on a nonaccrual status; (ii) classified
as "loss," "doubtful,"  "substandard" or "specially mentioned" by Tehama Bank or
any banking  regulators;  or (iii) on a  nonaccrual  status in  accordance  with
Tehama Bank's loan review procedures. Except as set forth on Schedule 3.16, none
of such assets (other than loans) are subject to any restrictions,  contractual,
statutory  or other,  that would  materially  impair  the  ability of the entity
holding such investment to dispose freely of any such assets at any time, except
restrictions  on the public  distribution  or transfer  of any such  investments
under the Securities Act and the regulations thereunder or state securities laws
and pledges or security interests given in connection with government  deposits.
All loans, leases or other extensions of credit  outstanding,  or commitments to
make any loans,  leases or other  extensions  of credit made by Tehama or Tehama
Bank to any  Affiliates of Tehama or Tehama Bank are disclosed on Schedule 3.16.
For  outstanding  loans or  extensions  of credit where the  original  principal
amounts are in excess of $50,000 and which by their terms are either  secured by
collateral  or  supported  by a guaranty  or similar  obligation,  the  security
interests  have  been  duly  perfected  in all  material  respects  and have the
priority they purport to have in all material respects,  other than by operation
of law, and, in the case of each guaranty or similar  obligation,  each has been
duly executed and delivered to Tehama or any Subsidiary,  including Tehama Bank,
and to Tehama's Knowledge, is still in full force and effect.

     Section  3.17 Brokers and  Finders.  Except as set forth on Schedule  3.17,
none of Tehama or any of its  Subsidiaries  is a party to or obligated under any
agreement with any broker or finder  relating to the  transactions  contemplated
hereby, and neither the execution of this Agreement,  the Merger Agreement,  nor
the consummation of the transactions provided for herein or therein, will result
in any  liability to any broker or finder.  Tehama  agrees to indemnify and hold
harmless  Humboldt and its  affiliates,  and to defend with counsel  selected by
Humboldt and reasonably  satisfactory to Tehama, from and against any liability,
cost or expense, including attorneys' fees, incurred in connection with a breach
of this Section 3.17.

     Section 3.18 Material Contracts. Schedule 3.18 to this Agreement contains a
complete and accurate  written list of all material  agreements,  obligations or
understandings,  written and oral, to which Tehama or any  Subsidiary is a party
as of the date of this  Agreement,  except  for loans and  other  extensions  of
credit made by Tehama or Tehama Bank in the ordinary  course of its business and
those items specifically disclosed in the Tehama Financial Statements.

     Section 3.19 Absence of Material Adverse Effect. Since January 1, 2000, the
respective  businesses of Tehama and its  Subsidiaries,  including  Tehama Bank,
have  been  conducted  only  in the  ordinary  course,  in the  same  manner  as
theretofore conducted,  and no event or circumstance has occurred or is expected
to occur which to Tehama's  Knowledge has had or which, with the passage of time
or otherwise,  could reasonably be expected to have a Material Adverse Effect on
Tehama.

     Section 3.20 Undisclosed Liabilities. Except as disclosed on Schedule 3.20,
none  of  Tehama  or any of its  Subsidiaries  to  Tehama's  Knowledge  has  any
liabilities or obligations,  either accrued,  contingent or otherwise,  that are
material to Tehama and its Subsidiaries and that have not been: (a) reflected or
disclosed in the Tehama  Financial  Statements;  or (b) incurred  subsequent  to
December 31, 1999, in the ordinary  course of business.  Tehama has no Knowledge
of any basis for the assertion against Tehama,  or any of its  Subsidiaries,  of
any  liability, obligation  or claim  (including without  limitation that of any

<PAGE>A-19

Governmental Entity) that will have or cause, or could reasonably be expected to
have or cause, a Material  Adverse Effect on Tehama that is not fully and fairly
reflected and disclosed in the Tehama Financial Statements or on Schedule 3.20.

profit-  sharing,  pension or retirement  benefits or social security  benefits,
whether  arising by operation  of law, by contract or by past custom,  have been
properly  accrued  for the  periods  covered  thereby  on the  Tehama  Financial

unfair  labor  practice  complaints,  strikes,  slowdowns,  stoppages  or  other
controversies  pending or, to the  Knowledge of Tehama,  attempts to unionize or
controversies  threatened  between  Tehama or any Subsidiary or Affiliate and or
relating to, any of their  employees that are likely to have a Material  Adverse
Effect on Tehama and its  Subsidiaries,  taken as a whole. None of Tehama or any
Subsidiary is a party to any collective bargaining agreement with respect to any
of their employees and, except as set forth on Schedule  3.21.1,  none of Tehama
or any Subsidiary is a party to a written employment  contract with any of their
respective  employees  and  there  are no  understandings  with  respect  to the
employment of any officer or employee of Tehama or any Subsidiary  which are not

paid or provided for in accordance with plan  documents.  Except as set forth on
Schedule 3.21.1, no director, officer or employee of Tehama or any Subsidiary is
entitled  to receive  any payment of any amount  under any  existing  agreement,
severance  plan or other  benefit  plan as a result of the  consummation  of any
transaction  contemplated by this Agreement or the Merger Agreement. To Tehama's
Knowledge,  Tehama  and its  Subsidiaries  have  materially  complied  with  all
applicable  federal and state  statutes and  regulations  which govern  workers'
compensation,  equal employment  opportunity and equal pay,  including,  but not

its  Subsidiaries  maintains,   administers  or  otherwise  contributes  to  any
"employee  benefit plan," as defined in Section 3(3) of ERISA,  which is subject
to any  provisions of ERISA and covers any employee,  whether active or retired,
of Tehama or any of its Subsidiaries  (any such plan being herein referred to as
an  "Employee  Plan").  True and  complete  copies of each such  Employee  Plan,
including  amendments thereto,  have been previously delivered or made available
to Humboldt, together with (i) all agreements regarding plan assets with respect
to such Employee Plans,  (ii) a true and complete copy of the annual reports for
the most  recent  three  years  (Form  5500  Series  including,  if  applicable,

most recent summary plan  description of each such Employee Plan,  together with
any  modifications  thereto,  and  (v) a  copy  of  the  most  recent  favorable

employer  plan" as covered in Section  412(c) of the IRC,  and none of Tehama or
any of its  Subsidiaries  has been obligated to make a contribution  to any such
multiemployer or multiple  employer plan within the past five years. None of the
Employee  Plans of  Tehama or any of its  Subsidiaries  is, or for the last five
years has  been,  subject  to Title IV of ERISA.  Each  Employee  Plan  which is
intended to be qualified  under  Section  401(a) of the IRC is so qualified  and
each trust  maintained  pursuant thereto is exempt from income tax under Section
501(a) of the IRC, and none of Tehama or any of its Subsidiaries is aware of any
fact which has  occurred  which  would cause the loss of such  qualification  or
exemption.

        3.21.4 Except as disclosed in Schedule 3.21.4,  none of Tehama or any of
its  Subsidiaries  maintains (other than base salary and base wages) any form of
current or deferred compensation, bonus, stock option, stock appreciation right,
severance pay, salary continuation,  retirement or incentive plan or arrangement
for the benefit of any director, officer or employee, whether active or retired,
of  Tehama  or any of its  Subsidiaries  or for any  class  or  classes  of such
directors,  officers or employees.  Except as disclosed in Schedule 3.21.4, none
of Tehama or any of its  Subsidiaries  maintains any group or individual  health
insurance,  welfare  or  similar  plan or  arrangement  for the  benefit  of any
director,  officer or  employee  of Tehama or any of its  Subsidiaries,  whether
active or retired,  or for any class or classes of such  directors,  officers or
employees. Any such plan or arrangement described in this Section 3.21.4, copies
of which have been  delivered or made  available  to  Humboldt,  shall be herein
referred to as a "Benefit Arrangement."

        3.21.5  All  Employee Plans and  Benefit  Arrangements  are operated  in
material  compliance with the  requirements  prescribed by any and all statutes,
governmental or court orders, or governmental rules or regulations  currently in
effect, including but not limited to ERISA and the IRC, applicable to such plans
or arrangements,  and plan documents relating to any such plans or arrangements,
materially  comply with or will be amended to materially  comply with applicable
legal requirements.  None of Tehama or any of its Subsidiaries, nor any Employee
Plan, nor any trusts created thereunder, nor any trustee,  administrator nor any
other fiduciary thereof,  has engaged in a "prohibited  transaction," as defined
in Section 406 of ERISA and Section 4975 of the IRC, that could  subject  Tehama
or any of its  Subsidiaries or Humboldt to liability under Section 409 or 502(i)
of ERISA or Section 4975 of the IRC or that would adversely affect the qualified
status of such plans;  each "plan official" within the meaning of Section 412 of

<PAGE>A-21

ERISA of each  Employee  Plan is bonded to the extent  required by such  Section
412; with respect to each Employee Plan, to Tehama's  Knowledge,  no employee of
Tehama or any Subsidiary, nor any fiduciary of any Employee Plan, has engaged in
any breach of  fiduciary  duty as defined in Part 4 of  Subtitle B of Title I of
ERISA which could  subject  Tehama or any of its  Subsidiaries  to  liability if
Tehama or any such  Subsidiary  is obligated to  indemnify  such Person  against
liability.  Except as disclosed in Schedule 3.21.5,  Tehama and its Subsidiaries
have not  failed to make any  material  contribution  or pay any  amount due and
owing  as  required  by  law or  the  terms  of any  Employee  Plan  or  Benefit
Arrangement.

        3.21.6  Except  as  set  forth on Schedule  3.21.6,  no Employee Plan or
Benefit  Arrangement  has any  material  liability  of any  nature,  accrued  or
contingent, including, without limitation, liabilities for federal, state, local
or foreign taxes, interest or penalty other than liability for claims arising in
the course of the administration of each such Employee Plan. Except as set forth
on Schedule  3.21.6,  to Tehama's  Knowledge  there is no pending or  threatened
legal action,  proceeding or investigation against any Employee Plan which could
result in material  liability to such Employee  Plan,  other than routine claims
for  benefits,  and there is no basis for any such legal  action,  proceeding or
investigation.

        3.21.7  Each  Benefit  Arrangement which is a group  health plan (within
the meaning of such term under IRC Section 4980B(g)(2))  materially complies and
has  materially  complied  with the  requirements  of Section 601 through 608 of
ERISA or Section 4980B of the IRC governing  continuation  coverage requirements
for employee-provided group health plans.

        3.21.8 Except as disclosed in Schedule 3.21.8,  none of Tehama or any of
its Subsidiaries  maintains any Employee Plan or Benefit Arrangement pursuant to
which any benefit or other  payment will be required to be made by Tehama or any
of its  Subsidiaries  or  Affiliates or pursuant to which any other benefit will
accrue or vest in any director,  officer or employee of Tehama or any Subsidiary
or  Affiliate  thereof,  in either case as a result of the  consummation  of the
transactions contemplated by this Agreement or the Merger Agreement.

     Section  3.22  Powers  of  Attorney.   No  power  of  attorney  or  similar
authorization  given by Tehama or any Subsidiary  thereof is presently in effect
or  outstanding  other than powers of attorney  given in the ordinary  course of
business with respect to routine matters.

     Section 3.23 Hazardous Materials. Except as set forth on Schedule 3.23:

        3.23.1 Except  for  ordinary and necessary  quantities of cleaning, pest
control and office supplies,  and other small quantities of Hazardous Substances
that are used in the ordinary course of the respective  businesses of Tehama and
its  Subsidiaries  and in  compliance  with  applicable  Environmental  Laws, or
ordinary rubbish,  debris and nonhazardous solid waste stored in garbage cans or
bins for regular  disposal  off-site,  or petroleum  contained in and de minimus
quantities  discharged from motor vehicles in their ordinary operation on any of
the Tehama  Properties (as defined below),  Tehama and its Subsidiaries have not
engaged in the generation, use, manufacture, treatment, transportation,  storage
(in tanks or otherwise),  or the disposal, of Hazardous Substances other than as
permitted by and only in compliance with applicable law. To Tehama's  Knowledge,
no  material  amount of  Hazardous  Substances  have been  released,  emitted or
disposed of, or otherwise  deposited,  on, in or from any real property which is
now or has been previously owned since January 1, 1997, or which is currently or
during the past three  years was leased,  by Tehama or any of its  Subsidiaries,
including  OREO  (collectively,   the  "Tehama  Properties"),   or  to  Tehama's
Knowledge, on or in any real property in which Tehama or any of its Subsidiaries

underlying  obligation  in  excess  of  $25,000  ("Tehama  Collateralizing  Real
Estate"),  except for (i) matters  disclosed on Schedule 3.23; (ii) ordinary and
necessary  quantities  of cleaning,  pest control and office  supplies  used and
stored in compliance with applicable  Environmental  Laws, or ordinary  rubbish,
debris and  nonhazardous  solid waste stored in garbage cans or bins for regular
disposal  off-site,  or  petroleum  contained  in,  and  de  minimus  quantities
discharged  from,  motor  vehicles in their  ordinary  operation  on such Tehama
Properties;  and (iii) such  releases,  emissions,  disposals or deposits  which
constituted  a  violation  of an  Environmental  Law but did not have a Material
Adverse  Effect on the  Tehama  Property  involved  and would not  result in the
incurrence  or  imposition of any  liability,  expense,  penalty or fine against
Tehama or any of its  Subsidiaries  in excess of $25,000  individually or in the
aggregate.  To Tehama's Knowledge, no activity has been undertaken on any of the
Tehama  Properties  since  January l, 1997,  and to the  Knowledge  of Tehama no
activities   have  been  or  are  being   undertaken   on  any  of  the   Tehama
Collateralizing Real Estate, that would cause or contribute to:

                (a) any of the Tehama Properties or Tehama Collateralizing  Real
Estate becoming a treatment,  storage or disposal facility within the meaning of
RCRA or any similar state law or local ordinance;

                (b) a release or threatened  release of any Hazardous Substances
under circumstances which would violate any Environmental Laws; or

                (c) the  discharge  of  Hazardous   Substances  into  any  soil,

any waters,  that would require a permit or any other approval under the Federal
Water  Pollution  Control Act, 33 U.S.C.  ss.1251 et seq., the Clean Air Act, as
amended, 42 U.S.C. ss.7401 et seq., or any similar federal or state law or local
ordinance;  the cumulative  effect of which would have a material adverse effect
on the Tehama Property or Tehama Collateralizing Real Estate involved.

        3.23.2 To  Tehama's Knowledge, there  are not, and  never have been, any
underground  storage tanks  located in or under any of the Tehama  Properties or
the Tehama Collateralizing Real Estate.

        3.23.3  None  of Tehama  or any of  its  Subsidiaries  has  received any
written notice of, and to Tehama's Knowledge none has received any verbal notice
of,  any   pending  or   threatened   claims,   investigations,   administrative
proceedings, litigation, regulatory hearings or requests or demands for remedial
or  responsive  actions or for  compensation,  with respect to any of the Tehama
Properties or Tehama Collateralizing Real Estate, alleging noncompliance with or

any federal, state or local agency.

        3.23.4  "Hazardous  Substances"  shall  mean  any  hazardous,  toxic  or

Subsidiaries  has all requisite  corporate power and authority to own, lease and
operate its properties and to carry on its business substantially as it is being

power or authority would not have a Material Adverse Effect on Humboldt taken as
a whole or the ability of Humboldt to consummate the  transactions  contemplated
by this Agreement.  Humboldt has all requisite  corporate power and authority to
enter into this  Agreement  and,  subject to obtaining all Requisite  Regulatory
Approvals,  Humboldt  will have the requisite  corporate  power and authority to

of  business of Humboldt  or any  Subsidiary,  nor the  location of any of their
respective  properties,   requires  that  Humboldt  or  any  of  its  respective
Subsidiaries  be licensed to conduct  business  in any  jurisdiction  other than
those  jurisdictions in which they are licensed or qualified to do business as a
foreign  corporation,  where the failure to be so licensed or  qualified  would,

Humboldt  and  its  Subsidiaries  have  all  material  licenses,   certificates,
franchises,  rights and  permits  that are  necessary  for the  conduct of their
respective  businesses,  and such licenses are in full force and effect,  except
for any failure to be in full force and effect that would not,  individually  or
in the aggregate,  have a Material  Adverse Effect on Humboldt taken as a whole,
or on the ability of Humboldt to consummate  the  transactions  contemplated  by
this Agreement.  The properties,  assets,  operations and businesses of Humboldt
and those of its  Subsidiaries,  are and have been maintained and conducted,  in
all material respects, in compliance with all applicable licenses, certificates,

cause to be issued,  delivered or sold,  additional  shares of capital  stock of
Humboldt or obligating  Humboldt to grant, extend or enter into any such option,
warrant,  call,  right,  commitment or agreement.  Humboldt also has outstanding

discovery of any such  noncompliance) and none contained any untrue statement of
a  material  fact or  omitted to state a  material  fact  required  to be stated
therein  or  necessary  to  make  the  statements   therein,  in  light  of  the
circumstances under which they were made, not misleading. The Humboldt Financial
Statements,  together  with the financial  statements  contained in the Humboldt
Filings,  have been prepared in accordance  with GAAP, or applicable  regulatory
accounting principles,  applied on a consistent basis during the period involved

in the case of the  unaudited  statements,  to recurring  adjustments  normal in
nature and amount)  the  consolidated  financial  position of Humboldt as of the
dates thereof and the

Filings comply in all material respects with applicable accounting  requirements
and have been  prepared  in  accordance  with  GAAP,  or  applicable  regulatory
accounting principles, applied on a consistent basis during the periods involved
(except  as may be  indicated  in  the  notes  thereto,  or in the  case  of the
unaudited  statements,  as permitted by regulations of the Federal Reserve Bank,
the  FDIC,  or the  CDFI),  and  fairly  present  (subject,  in the  case of the
unaudited statements,  to recurring adjustments normal in nature and amount) the

and regulations thereunder.

        4.7.3  Humboldt  has  delivered  or  will  deliver  to Tehama copies of:
(a) the audited  balance sheets of Humboldt and its  Subsidiaries as of December

shareholders'  equity and cash  flows for the years  then ended and the  related
notes  to  such  financial  statements,  all as  audited  by  Richardson  & Co.,

additional  financial  statements of Humboldt as provided in Section 5.1.1(iii).
The Humboldt Financial Statements have been prepared (and all of said additional
financial  statements  will be prepared) in accordance  with GAAP, or applicable
regulatory  accounting  principles,  applied on a  consistent  basis  during the
periods involved (except as may be indicated in the notes thereto)  consistently

Schedule 4.8, to the best of Humboldt's Knowledge,  the respective businesses of
Humboldt and its  Subsidiaries  are not being conducted in violation of any law,
ordinance or regulation,  except for  violations  which  individually  or in the
aggregate  would  not  have a  Material  Adverse  Effect  on  Humboldt  and  its
Subsidiaries,  taken as a whole. No  investigation or review by any Governmental
Entity with  respect to Humboldt is pending or, to the  Knowledge  of  Humboldt,
threatened,  nor has any Governmental  Entity indicated to Humboldt an intention
to conduct  the same,  other than those the  outcome of which,  as far as can be
reasonably foreseen, will not have a Material Adverse Effect on Humboldt and its
Subsidiaries, taken as a whole.

     Section 4.9  Litigation.  Except as disclosed on Schedule 4.9,  there is no
suit,  action or  proceeding  or  investigation  pending or, to the Knowledge of
Humboldt,  threatened  against or affecting  Humboldt or any of its Subsidiaries
which, if adversely determined, would have a Material Adverse Effect on Humboldt
and its  Subsidiaries,  taken as a whole;  nor is there  any  judgment,  decree,
injunction,  rule or order of any Governmental Entity or arbitrator  outstanding
against  Humboldt  or any of its  Subsidiaries  that has,  or which,  insofar as
reasonably can be foreseen,  in the future would have, any such Material Adverse
Effect.  Schedule 4.9  contains a true,  correct and  complete  list,  including

any, subject to reservation of rights, if any, the applicable deductible and the
amount of any reserve therefor,  of all pending  litigation in which Humboldt or
any of its  Subsidiaries  is a named party of which Humboldt has Knowledge,  and
except  as  disclosed on Schedule  4.9, all  of  the  litigation  shown  on such

<PAGE>A-28

deductibles,  or has been adequately  reserved for in accordance with Humboldt's
prior business practices.

assets.  Schedule  4.11  contains a list of all policies of insurance  and bonds
carried and owned by Humboldt or any Subsidiary.  None of Humboldt or any of its
Subsidiaries  is in default under any such policy of insurance or bond such that
it can be canceled and all material current claims thereunder have been filed in
timely  fashion.  Humboldt and its  Subsidiaries  have filed claims  outstanding
with, or given notice of claim to, their insurers or bonding companies in timely
fashion  with  respect to all material  matters and  occurrences  for which they
believe they have coverage.

     Section 4.12 Title to Assets other than Real Property. Each of Humboldt and
its  respective  Subsidiaries  has  good  and  marketable  title  to or a  valid

mortgages,  covenants,  conditions,  restrictions,  easements,  liens,  security
interests, charges, claims, assessments and encumbrances, except for: (a) rights
of lessors,  lessees or sublessees in such matters as are reflected in a written
lease; (b) encumbrances as set forth in the Humboldt Financial  Statements;  (c)
current Taxes  (including  assessments  collected  with Taxes) not yet due which
have been fully reserved for; (d) encumbrances, if any, that are not substantial
in character,  amount or extent and do not detract materially from the value, or
interfere with present use, or the ability of Humboldt or its Subsidiary to sell
or otherwise  dispose of the property subject thereto or affected  thereby;  and
(e) other matters as described in Schedule 4.12.  Materially all such properties
and assets are,  and require  only  routine  maintenance  to keep them,  in good
working condition, normal wear and tear excepted.

     Section 4.13 Real  Property.  Schedule 4.13 is an accurate list and general
description  of all real  property  owned or  leased by  Humboldt  or any of its
Subsidiaries,  including OREO. Each of Humboldt and its respective  Subsidiaries
has good and marketable  title to the real properties that it owns, as described
in such  Schedule,  free and  clear  of all  mortgages,  covenants,  conditions,
restrictions, easements, liens, security interests, charges, claims, assessments
and  encumbrances,  except for (a) rights of lessors,  lessees or  sublessees in
such matters as are reflected in a written lease;  (b) current Taxes  (including
assessments collected with Taxes) not yet due and payable; (c) encumbrances,  if
any,  that  are not  substantial  in  character,  amount  or  extent  and do not

of Humboldt to dispose,  of Humboldt's  interest in the property subject thereto
or affected  thereby;  and (d) other  matters as  described  in  Schedule  4.13.
Humboldt and its Subsidiaries  have valid leasehold  interests in the leaseholds
they  respectively  hold,  free and  clear  of all  mortgages,  liens,  security

of lessors,  co-lessees  or  sublessees  in such  matters as are  reflected in a
written lease; (b) title exceptions affecting the fee estate of the lessor under
such leases; and (c) other matters as described in Schedule 4.13. To the best of
Humboldt's  Knowledge,  the  activities  of Humboldt and its  Subsidiaries  with
respect to all real property owned or leased by them for use in connection  with
their  operations  are in all material  respects  permitted  and  authorized  by
applicable zoning laws,  ordinances and regulations and all laws and regulations

<PAGE>A-29

of any Governmental  Entity.  Except as set forth in Schedule 4.13, Humboldt and
its Subsidiaries  enjoy quiet possession under all material leases to which they
are the  lessees  and all of such leases are valid and in full force and effect,
except as the enforceability  thereof may be limited by bankruptcy,  insolvency,
moratorium or other similar laws affecting the rights of creditors generally and
by general  equitable  principles.  Materially all buildings and improvements on
real properties  owned or leased by Humboldt or any of its  Subsidiaries  are in
good  condition  and  repair,  and do not  require  more than normal and routine
maintenance, to keep them in such condition, normal wear and tear excepted.

     Section 4.14 Performance of Obligations. Humboldt and its Subsidiaries have
performed all material  obligations required to be performed by them to date and
none of Humboldt or any of its  Subsidiaries is in material  default under or in
breach of any term or provision of any covenant,  contract,  lease, indenture or
any other agreement,  written or oral, to which any is a party, is subject or is
otherwise  bound,  and no event has occurred that,  with the giving of notice or
the passage of time or both,  would  constitute such a default or breach,  where
such  default  or breach or failure  to  perform  would have a Material  Adverse
Effect  on  Humboldt  and its  Subsidiaries,  taken  as a whole.  To  Humboldt's
Knowledge, and except as disclosed on Schedule 4.14, no party with whom Humboldt
or any of its  Subsidiaries  has an agreement that is of material  importance to
the business of Humboldt and its  Subsidiaries,  taken as a whole, is in default
thereunder.

     Section  4.15 Brokers and  Finders.  Except as set forth on Schedule  4.15,
none of Humboldt or any of its Subsidiaries is a party to or obligated under any
agreement with any broker or finder  relating to the  transactions  contemplated
hereby,  and neither the execution of the Agreement,  the Merger Agreement,  nor
the  consummation  of the  transactions  provided for herein and  therein,  will
result in any  liability to any broker or finder.  Humboldt  agrees to indemnify
and  hold  harmless  Tehama  and its  affiliates,  and to  defend  with  counsel
reasonably  satisfactory  to Tehama,  from and  against any  liability,  cost or
expense, including attorneys' fees, incurred in connection with a breach of this
Section 4.15.

     Section 4.16 Absence of Material Adverse Effect. Since January 1, 2000, the
respective  businesses of Humboldt and its Subsidiaries have been conducted only
in the  ordinary  course,  in  substantially  the  same  manner  as  theretofore
conducted,  and no event or  circumstance  has  occurred or is expected to occur
which to  Humboldt's  Knowledge  has had or which,  with the  passage of time or
otherwise,  could  reasonably be expected to have a Material  Adverse  Effect on
Humboldt and its Subsidiaries, taken as a whole.

     Section 4.17 Undisclosed Liabilities. Except as disclosed on Schedule 4.17,

been: (a) reflected or disclosed in the Humboldt  Financial  Statements;  or (b)
incurred  subsequent to December 31, 1999,  in the ordinary  course of business.
Humboldt has no Knowledge of any basis for the assertion against Humboldt or any
of its Subsidiaries,  of any liability,  obligation or claim (including  without
limitation  that of any  Governmental  Entity) that will have or cause, or could
reasonably be expected to have or cause,  a Material  Adverse Effect on Humboldt
and its  Subsidiaries,  taken as a whole,  that is not fairly  reflected  in the
Humboldt Financial Statements or on Schedule 4.17.

Subsidiaries,  including OREO (collectively,  the "Humboldt Properties"),  or to
Humboldt's Knowledge, on or in any real property in which Humboldt or any of its
Subsidiaries now holds any security interest, mortgage or other lien or interest
with an underlying  obligation in excess of $25,000  ("Humboldt  Collateralizing
Real Estate"),  except for (i) matters disclosed on Schedule 4.19; (ii) ordinary
and necessary quantities of cleaning,  pest control and office supplies used and
stored in compliance with applicable  Environmental  Laws, or ordinary  rubbish,
debris and  nonhazardous  solid waste stored in garbage cans or bins for regular
disposal  off-site,  or  petroleum  contained  in,  and  de  minimus  quantities
discharged  from,  motor vehicles in their  ordinary  operation on such Humboldt
Properties;  and (iii) such  releases,  emissions,  disposals or deposits  which
constituted  a  violation  of an  Environmental  Law but did not have a Material
Adverse  Effect on the  Humboldt  Property  involved and would not result in the
incurrence  or  imposition of any  liability,  expense,  penalty or fine against
Humboldt or any of its Subsidiaries in excess of $25,000  individually or in the
aggregate.  To Humboldt's  Knowledge,  no activity has been undertaken on any of
the Humboldt  Properties since January l, 1997, and to the Knowledge of Humboldt
no  activities  have  been  or are  being  undertaken  on  any  of the  Humboldt
Collateralizing Real Estate, that would cause or contribute to:

                (a)  any  of the Humboldt Properties or Humboldt Collateralizing
Real  Estate  becoming a  treatment,  storage or  disposal  facility  within the
meaning of RCRA or any similar state law or local ordinance;

                (b)  a release or threatened release of any Hazardous Substances
under circumstances which would violate any Environmental Laws; or

<PAGE>A-32

                (c)  the  discharge  of  Hazardous  Substances  into  any  soil,
subsurface  water or ground water or into the air, or the dredging or filling of
any waters,  that would require a permit or any other approval under the Federal
Water  Pollution  Control Act, 33 U.S.C.  ss.1251 et seq., the Clean Air Act, as
amended, 42 U.S.C. ss.7401 et seq., or any similar federal or state law or local
ordinance;  the cumulative  effect of which would have a material adverse effect
on the Humboldt Property or Humboldt Collateralizing Real Estate involved.

        4.19.2 To  Humboldt's  Knowledge,  there  are not,  and never have been,
any underground storage tanks located in or under any of the Humboldt Properties
or the Humboldt Collateralizing Real Estate.

        4.19.3 None  of  Humboldt or  any of its  Subsidiaries  has received any
written  notice of, and to  Humboldt's  Knowledge  none has  received any verbal
notice of, any  pending or  threatened  claims,  investigations,  administrative
proceedings, litigation, regulatory hearings or requests or demands for remedial
or responsive  actions or for compensation,  with respect to any of the Humboldt
Properties or Humboldt  Collateralizing Real Estate, alleging noncompliance with
or violation of any  Environmental Law or seeking relief under any Environmental
Law and none of the Humboldt Properties or Humboldt  Collateralizing Real Estate
is  listed on the  United  States  Environmental  Protection  Agency's  National
Priorities List of Hazardous Waste Sites, or, to Humboldt's Knowledge, any other
list, schedule,  log, inventory or record of hazardous waste sites maintained by
any federal, state or local agency.

     Section 4.20 Employees.

        4.20.1  Except  as set  forth in Schedule  4.20.1, there are no material
controversies  pending or threatened between Humboldt or any of its Subsidiaries
and any of their employees.

        4.20.2 Except  as  disclosed  in  the Humboldt  Financial  Statements at
December 31, 1999,  or in Schedule  4.20.2,  all material  sums due for employee
compensation  and benefits have been duly and  adequately  paid or provided for,
and all deferred compensation obligations are fully funded. Neither Humboldt nor
Humboldt Bank,  Capitol Valley Bank and Capitol Thrift & Loan, is a party to any
collective  bargaining  agreement  with  respect to any of its  employees or any
labor organization to which its employees or any of them belong.

        4.20.3  To  Humboldt's  Knowledge,  no  governmental agency  or claimant
or representative of such claimant has alleged a material  violation of ERISA by
Humboldt,  the  liability of which,  if adversely  determined  would result in a
material adverse change in the capital or earnings of Humboldt.

     Section  4.21  Powers  of  Attorney.   No  power  of  attorney  or  similar
authorization given by Humboldt or any Subsidiary thereof is presently in effect
or  outstanding  other than powers of attorney  given in the ordinary  course of
business with respect to routine matters.

     Section 4.22 Loans and  Investments.  Except as set forth on Schedule 4.22,
all loans,  leases and other  extensions  of credit,  and  guaranties,  security
agreements or other agreements supporting any loans or extensions of credit, and
investments  of  Humboldt  or its  Subsidiaries,  are,  and  constitute,  in all
material  respects,  the legal,  valid and  binding  obligations  of the parties
thereto and are enforceable against such parties in accordance with their terms,
except as the  enforceability  thereof  may be  limited  by  applicable  law and
otherwise by bankruptcy,  insolvency, moratorium or other similar laws affecting

<PAGE>A-33

the rights of creditors generally and by general equitable principles. Except as
described on Schedule 4.22, as of July 31, 2000, no loans or investments held by
Humboldt or any Subsidiary, are: (i) more than ninety days past due with respect
to any  scheduled  payment  of  principal  or  interest,  other  than loans on a
nonaccrual  status;  (ii)  classified as "loss,"  "doubtful,"  "substandard"  or
"specially mentioned" by Humboldt Bank, Capitol Valley Bank and Capitol Thrift &
Loan, or any banking  regulators;  or (iii) on a nonaccrual status in accordance
with Humboldt  Bank's,  Capitol Valley Bank's and Capitol Thrift & Loan's,  loan
review  procedures.  Except as set forth on Schedule  4.22,  none of such assets
(other than loans) are subject to any  restrictions,  contractual,  statutory or
other,  that would  materially  impair the  ability of the entity  holding  such
investment to dispose freely of any such assets at any time, except restrictions
on the  public  distribution  or  transfer  of any such  investments  under  the
Securities  Act and the  regulations  thereunder  or state  securities  laws and
pledges or security interests given in connection with government deposits.  All
loans, leases or other extensions of credit outstanding,  or commitments to make
any loans,  leases or other  extensions  of credit  made by Humboldt or Humboldt
Bank,  Capitol  Valley  Bank and Capitol  Thrift & Loan,  to any  Affiliates  of
Humboldt or Humboldt  Bank,  Capitol  Valley Bank and Capitol Thrift & Loan, are
disclosed on Schedule 4.22. For outstanding  loans or extensions of credit where
the  original  principal  amounts are in excess of  $100,000  and which by their
terms are either  secured by  collateral  or  supported by a guaranty or similar
obligation,  the  security  interests  have been duly  perfected in all material
respects  and have the priority  they purport to have in all material  respects,
other than by  operation  of law,  and, in the case of each  guaranty or similar
obligation,  each has been  duly  executed  and  delivered  to  Humboldt  or any
Subsidiary, and to Humboldt's Knowledge, is still in full force and effect.

     Section 4.23 Material Contracts. Schedule 4.23 to this Agreement contains a
complete and accurate  written list of all material  agreements,  obligations or
understandings, written and oral, to which Humboldt or any Subsidiary is a party
as of the date of this  Agreement,  except  for loans and  other  extensions  of
credit made by  Humboldt  or its  Subsidiaries,  in the  ordinary  course of its
business  and those  items  specifically  disclosed  in the  Humboldt  Financial
Statements.

     Section 4.24 Effective Date of Representations,  Warranties,  Covenants and
Agreements.  Each representation,  warranty,  covenant and agreement of Humboldt
set  forth in this  Agreement  shall be  deemed to be made on and as of the date
hereof and as of the Effective Time.

                        ARTICLE 5. ADDITIONAL AGREEMENTS

     Section 5.1 Access to Information, Due Diligence, etc.

        5.1.1 Upon  reasonable  notice,  each party shall permit the other party
and its  accountants,  counsel and other  representatives  reasonable  access to
their officers, employees, properties, books, contracts, commitments and records
and from the date  hereof  through  the  Effective  Time,  and shall  furnish or
provide  access  to each  other  as soon as  practicable,  (i) a copy of each of
Tehama's  Filings or  Humboldt's  Filings  filed  subsequent to the date of this
Agreement  promptly  after such  document  has been  filed with the  appropriate
Governmental Entity,  provided,  however, that copies of any Returns relating to
Taxes of Tehama or any of its  Subsidiaries  shall be  furnished  to Humboldt at
least 15 Business  Days prior to the proposed  date of filing  thereof and shall
not be filed without the prior reasonable  approval of Humboldt,  which approval
shall not be unreasonably  withheld or delayed; (ii) unless otherwise prohibited
by law, a copy of each report, schedule and other documents filed or received by
it during such period with any  Regulatory  Authority  or the  Internal  Revenue
Service, as to documents other than related to employees or  customers and other

<PAGE>A-34

other  than  those  distributed  to  banks  generally;   (iii)  as  promptly  as
practicable  following the end of each calendar  month after the date hereof,  a
balance  sheet of Tehama or Humboldt  as of the end of such month;  and (iv) all
other  information  concerning  its  business,   properties,  assets,  financial
condition, results of operations, liabilities, personnel and otherwise as Tehama
or Humboldt may reasonably request.

        5.1.2 Until the  Effective  Time, a  representative of Humboldt shall be
entitled  and shall be invited to attend  meetings of the Board of  Directors of
Tehama or Tehama Bank and of the Loan and Audit  Committees of Tehama and Tehama
Bank, and at least five (5) days' prior written  notice of the dates,  times and
places of such  meetings  shall be given to Humboldt  except that in the case of
special meetings Humboldt shall receive the same number of days' prior notice as
Tehama's  directors  receive for such  meetings;  provided,  however,  that such
representative  shall  excuse  himself or herself  from any  portion of any such
meetings  that (i) relate to approval of, or the  exercise of any rights  under,
this  Agreement  by  Tehama,  (ii)  involve  discussions  between  such Board of
Directors or such Loan or Audit  Committee and legal counsel for Tehama that are
entitled to be protected  from  disclosure  under an  attorney-client  privilege
which would be lost due to the presence of such  representative of Humboldt,  or
(iii) constitute the Executive Session of any Board of Directors meeting.

        5.1.3 Until  the  Effective  Time,  a representative  of Tehama shall be
entitled  and shall be invited to attend  meetings of the Boards of Directors of
Humboldt and Humboldt Bank, and of the Loan and Audit Committees of Humboldt and
Humboldt  Bank,  at least five (5) days'  prior to written  notice of the dates,
times and places of such  meetings  shall be given to Tehama  except that in the
case of special  meetings  Tehama  shall  receive the same number of days' prior
notice as Humboldt's  directors  receive for such meetings;  provided,  however,
that such representative shall excuse himself or herself from any portion of any
such  meetings  that (i) relate to  approval  of, or the  exercise of any rights
under, this Agreement by Humboldt,  (ii) involve discussions between such Boards
of Directors  or such Loan or Audit  Committees  and legal  counsel for Humboldt
that are  entitled to be  protected  from  disclosure  under an  attorney-client
privilege  which  would be lost due to the  presence of such  representative  of
Tehama,  or (iii)  constitute  the  Executive  Session of any Board of Directors
meeting.

        5.1.4  Humboldt  and  Tehama  each agrees to keep  confidential  and not
divulge to any other party or Person  (other than to the  employees,  attorneys,
accountants and consultants of each who have a need to receive such  information
and other than as may be  required  by law) any  information  received  from the
other,  unless and until such documents and other information  otherwise becomes
publicly available or unless the disclosure of such information is authorized by
each party.  In the event of termination  of this Agreement for any reason,  the
parties shall  promptly  return,  or at the election of the other party destroy,
all nonpublic  documents obtained from the other and any copies or notes of such
documents  (except as  otherwise  required by law) and,  upon the request of the
other party, confirm such destruction to the other in writing.

     Section 5.2 Shareholder Approval.

        5.2.1 Tehama  and  Humboldt  each shall   promptly call a meeting of its
respective  shareholders to be held at the earliest  practicable  date after the
date on which the initial  Registration  Statement is filed with the SEC, but in
no event  later than  December  31,  2000,  for the  purpose of  approving  this
Agreement  and  authorizing  the Merger  Agreement  and the Merger.  Each of the
respective  Boards of Directors will  recommend to the  respective  shareholders
approval of this  Agreement,  the Merger  Agreement  and the  Merger;  provided,
however, that  Tehama's Board  of Directors or Humboldt's Board of Directors may

<PAGE>A-35

withdraw its  recommendation  if such Board of Directors  believes in good faith
(based on a written  opinion  of a  financial  advisor  that is  experienced  in
evaluating  the  fairness  of  Acquisition  Proposals)  that a  Tehama  Superior
Proposal or Humboldt Superior Proposal,  as applicable  (defined below) has been
made and shall have determined in good faith,  after consultation with and based
on written  advice of its outside  legal  counsel,  that the  withdrawal of such
recommendation  is  necessary  for such Board of  Directors  to comply  with its
fiduciary duties under applicable law.

        5.2.2 If the Merger is  approved by vote of the shareholders of Humboldt
and Tehama, then, within ten (10) days thereafter Humboldt and Tehama shall send
a Dissenting Shareholder Notice to each recordholder of any Dissenting Shares.

     Section 5.3 Taking of Necessary Action.

        5.3.1 Subject to the terms and conditions of this Agreement, each of the
parties hereto agrees,  subject to applicable  laws and the fiduciary  duties of
Tehama's  or  Humboldt's  Boards of  Directors,  as  advised in writing by their
respective  counsel,  to use all reasonable efforts promptly to take or cause to
be taken all action and promptly to do or cause to be done all things necessary,
proper or advisable under applicable laws and regulations to consummate and make
effective  the  transactions  contemplated  by this  Agreement  and  the  Merger
Agreement,  including,  without  limitation,  the delivery of any certificate or
other  document  reasonably  requested by counsel to a party to this  Agreement.
Without  limiting the foregoing,  Humboldt and Tehama will use their  reasonable
efforts  to  obtain  all  consents  of third  parties  and  Government  Entities
necessary or, in the reasonable  opinion of Humboldt or Tehama advisable for the
consummation  of  the  transactions  contemplated  by  this  Agreement.  Without
limiting the foregoing, Humboldt shall take all actions necessary to execute and
file the Merger  Agreement and to effect all  transactions  contemplated by this
Agreement and Tehama shall take all actions necessary to effect all transactions
contemplated  by this  Agreement and the Merger  Agreement.  In case at any time
after the Effective  Time any further  action is necessary or desirable to carry
out the  purposes  of this  Agreement,  the  Merger  Agreement,  or to vest  the
Surviving  Corporation  with  full  title  to all  properties,  assets,  rights,
approvals, immunities and franchises of Tehama, the proper officers or directors
of Humboldt or Tehama, as the case may be, shall take all such necessary action.
Notwithstanding  the foregoing,  nothing in this Agreement shall be construed to
require  Tehama to take any action (or omit to take any action) which may affect
the Conversion Rate,  except as may be specifically  provided for or required by
this Agreement.

        5.3.2 The obligations  of Tehama or Humboldt  contained in Section 6.2.5
of this  Agreement  shall  continue  to be in full force and effect  despite any
Default thereof by reason of receipt of a Tehama  Superior  Proposal or Humboldt
Superior Proposal,  as applicable (defined below) and any Default thereof by the
defaulting  party  shall  entitle  either  Tehama or  Humboldt  to such legal or
equitable   remedies  as  may  be  provided   in  this   Agreement   or  by  law
notwithstanding  that any  action  or  inaction  of the  Board of  Directors  or
officers  of the  defaulting  party  which is  required  to enable such party to
fulfill  such  obligations  may be  excused  based on the  continuing  fiduciary
obligations of such party's Board of Directors and officers to its shareholders.
Notwithstanding  the foregoing,  however,  in the event of a termination of this
Agreement by Humboldt or Tehama and the actual payment of the liquidated damages
to the other party as provided  for in Section  8.5 of this  Agreement,  neither
Humboldt,  Tehama or their  respective  directors  or  officers  shall  have any
obligations  or  liabilities  of any kind under this  Agreement by reason of any
such Default,  and Humboldt or Tehama shall have no further  obligations  of any
kind under this Agreement.

<PAGE>A-36

        5.3.3  Tehama  shall  use  its  best  efforts  to  cause  each director,
executive officer and other Person who is an "Affiliate" of Tehama (for purposes
of Rule 145 under the  Securities  Act) to deliver to  Humboldt,  on the date of
this Agreement,  a written  agreement in the form attached hereto as Exhibit 5.3
(the "Affiliate Agreements").

     Section 5.4 Registration Statement and Applications.

        5.4.1 Humboldt  and  Tehama will cooperate and jointly  prepare and file
as  promptly  as  practicable  the  Registration   Statement,   the  statements,
applications,  correspondence  or  forms  to be  filed  with  appropriate  State
securities law regulatory  authorities,  and the statements,  correspondence  or
applications  to be  filed to  obtain  the  Requisite  Regulatory  Approvals  to
consummate the transactions contemplated by this Agreement. Each of Humboldt and
Tehama shall use all reasonable  efforts to have the S-4 Registration  Statement
declared  effective  under the Securities  Act as promptly as practicable  after
such filing,  and thereafter  mail the Joint Proxy  Statement/Prospectus  to the
shareholders  of  Tehama.  Each  party  will  furnish  all  financial  or  other
information,    including   accountant   comfort   letters   relating   thereto,
certificates,   consents  and  opinions  of  counsel   concerning   it  and  its
Subsidiaries received by such party.

        5.4.2 Each  party shall provide to the other at the request of the other
party:  (i)  immediately  prior to the filing  thereof,  copies of all  material
statements,  applications,  correspondence  or  forms  to be  filed  with  state
securities law regulatory authorities,  the SEC and other appropriate regulatory
authorities  to obtain the  Requisite  Regulatory  Approvals to  consummate  the
transactions contemplated by this Agreement; provided, however, that no approval
need be obtained from any party to which such  materials are provided;  and (ii)
promptly after delivery to, or receipt from,  such  regulatory  authorities  all
written  communications,  letters,  reports or other  documents  relating to the
transactions contemplated by this Agreement.

     Section 5.5 Expenses.

        5.5.1  Whether  or not the Merger is consummated, all costs and expenses
incurred in connection  with this  Agreement and the  transactions  contemplated
hereby  shall  be paid by the  party  incurring  the  same,  including,  without
limitation,  all costs  associated  with any resales of Humboldt Common Stock by
Affiliates  of Tehama;  provided,  however,  that Humboldt will file on a timely
basis at its own expense the reports  required by Rule 144(c) of the  Securities
Act.

        5.5.2 Tehama  and Humboldt  shall  use their best efforts to ensure that
their attorneys,  accountants,  financial advisors, investment bankers and other
consultants  engaged by them in connection with the transaction  contemplated by
this  Agreement  submit full and final  bills on or before the Closing  Date and
that all such expenses are paid or properly accrued prior to the Closing Date.

     Section 5.6 Notification of Certain Events.

        5.6.1 Tehama shall provide to Humboldt, as soon as  practicable, written
notice (sent via facsimile and overnight  mail or courier) of the  occurrence or
failure to occur of any of the events,  circumstances or conditions that are the
subject of Sections 6.1 and 6.2, which notice shall provide reasonable detail as
to the subject matter thereof.

<PAGE>A-37

        5.6.2 Humboldt shall provide to Tehama,  as soon as practicable, written
notice (sent via facsimile and overnight  mail or courier) of the  occurrence or
failure to occur of any of the events,  circumstances or conditions that are the
subject of Section 6.3 and 6.4, which notice shall provide  reasonable detail as
to the subject matter thereof.

        5.6.3  Each  party  shall  promptly  advise the others in writing of any
change or event which could  reasonably  be expected to have a Material  Adverse
Effect on the business,  properties,  assets,  financial  condition,  results of
operations,  liabilities  or  personnel  of  such  party  or on its  ability  to
consummate  the  transactions  contemplated  by  this  Agreement  or the  Merger
Agreement.

        5.6.4 Tehama and Humboldt shall  immediately notify the other in writing
in the event that such party  becomes aware that the  Registration  Statement or
Joint Proxy  Statement/Prospectus at any time contains any untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary in order to make the statement therein,  in light of the circumstances
under which they were made, not misleading or that the Registration Statement or
the Joint  Proxy  Statement/Prospectus  otherwise  is required to be amended and
supplemented,   which  notice  shall   specify,   in  reasonable   detail,   the
circumstances  thereof.  Humboldt  shall  promptly  amend  and  supplement  such
materials and disseminate the new or modified  information so as to fully comply
with the Securities  Act. If the amendment or supplement so required  relates to
information   concerning  Tehama,  the  out-of-pocket   costs  and  expenses  of
preparing,  filing and disseminating such amendment or supplement shall be borne
by Tehama.

     Section  5.7  Closing  Schedules.  Tehama has  delivered  to Humboldt on or
before the date of this Agreement all of the Schedules to this  Agreement  which
Tehama is required to deliver to Humboldt  hereunder  (the "Tehama  Schedules").
Humboldt has delivered to Tehama on or before the date of this  Agreement all of
the Schedules to this Agreement  which Humboldt is required to deliver to Tehama
hereunder ( the "Humboldt  Schedules").  Immediately  prior to the Closing Date,
Tehama shall have prepared updates of the Tehama Schedules  provided for in this
Agreement and shall deliver to Humboldt revised schedules containing the updated
information (or a certificate signed by Tehama's Chief Executive Officer stating
that there have been no changes on the applicable schedules); and Humboldt shall
have prepared updates of the Humboldt  Schedules  provided for in this Agreement
and shall deliver to Tehama revised Schedules containing updated information (or
a certificate  signed by Humboldt's  Chief Executive  Officer stating that there
has been no change on the applicable  schedules).  Such updated  schedules shall
sometimes be referred to collectively,  as the "Closing  Schedules." The Closing
Schedules  shall be dated as of the day  prior  to the  Closing  Date and  shall
contain  information  as of the  day  prior  to the  Closing  Date or as of such
earlier date as is practicable under the circumstances. In the event the Closing
Schedules  disclose an event,  occurrence or circumstance  that has had or could
reasonably be expected to have a Material  Adverse Effect on Tehama,  on the one
hand, or on Humboldt,  on the other hand, or on consummation of the transactions
contemplated  by this  Agreement,  that  was  not  disclosed  in the  previously
delivered  Schedules  hereto,  the party delivering such Closing  Schedules (the
"Affected  Party") shall so notify the other party in the letter of  transmittal
for such  Closing  Schedules,  the  Closing  Date shall be delayed for seven (7)
Business Days and such other party shall be entitled to terminate this Agreement
within five (5)  Business  Days after  receiving  such  Closing  Schedules  that
disclose  such  event,  occurrence  or  circumstance.  In the  event of any such
termination, the terminating party shall have no liability for such termination.
The Affected Party shall have no liability to the  terminating  party in such an
event  unless (i) as a result of the  existence  of such  event,  occurrence  or
circumstance so disclosed in the Closing Schedules any of the representations or
warranties of the Affected  Party  contained in this Agreement are found to have
been untrue in any material  respect as of the date of this  Agreement,  or (ii)

<PAGE>A-38

the event,  occurrence or circumstance could have been prevented in the exercise
of reasonable  diligence by any officers or directors of the Affected  Party, in
either of which  cases the  Affected  Party  shall be liable to the  terminating
party for Liquidated Damages as provided in Section 8.5 hereof.

     Section  5.8  Additional  Accruals/Appraisals.  Immediately  prior  to  the
Closing Date, at Humboldt's request, Tehama and/or Tehama Bank shall, consistent
with GAAP and applicable banking regulations, establish such additional accruals
and reserves as may be necessary to conform Tehama's or Tehama Bank's accounting
and credit and OREO loss  reserve  practices  and methods to those of  Humboldt,
provided,  however,  that no accrual or  reserve  made by Tehama or Tehama  Bank
pursuant to this Section 5.8, or any litigation or regulatory proceeding arising
out of any such accrual or reserve, or any other effect on Tehama or Tehama Bank
resulting from Tehama's or Tehama Bank's compliance with this Section 5.8, shall
constitute  or be deemed to be a breach,  violation of or failure to satisfy any
representation,  warranty,  covenant,  condition  or  other  provision  of  this
Agreement or otherwise be  considered  in  determining  whether any such breach,
violation or failure to satisfy shall have occurred.

                         ARTICLE 6. CONDUCT OF BUSINESS

     Section 6.1 Affirmative Conduct of Tehama.  During the period from the date
of execution of this Agreement through the Effective Time, Tehama shall carry on
its business,  and shall cause each of its respective  Subsidiaries  to carry on
its  business,  in the  ordinary  course in  substantially  the  manner in which
heretofore  conducted,  subject to changes in law  applicable to all  California
state-chartered  banks or all member  banks  insured by the FDIC and  directives
from regulators,  and use all commercially reasonable efforts to preserve intact
its  business  organization,  keep  available  the  services of its officers and
employees,  (other than  terminations  in the ordinary  course of business)  and
preserve its  relationships  with  customers,  depositors,  suppliers and others
having business  dealings with it; and, to these ends, shall fulfill each of the
following:

        6.1.1 Use its commercially reasonable efforts, or cooperate with others,
to  expeditiously  bring about the  satisfaction of the conditions  specified in
Article 7 which are within its ability to influence or control;

        6.1.2  Advise Humboldt promptly in writing of any change that would have
a Material Adverse Effect on its capital structure, financial condition, assets,
results of  operations,  business or prospects or of any matter which would make
the  representations  and  warranties set forth in Article 3 hereof not true and
correct in any material  respect as of the  effective  date of the  Registration
Statement and at the Effective Time;

        6.1.3   Keep  in  full  force  and  effect  all of its existing material
permits and licenses and those of its Subsidiaries;

        6.1.4  Use  its  commercially   reasonable efforts to maintain insurance
or bonding  coverage on all material  properties for which it is responsible and
on its  business  operations,  and  carry not less  than the same  coverage  for
fidelity,  public  liability,  personal injury,  property damage and other risks
equal to that  which is in effect as of the date of this  Agreement;  and notify
Humboldt in writing  promptly of any facts or  circumstances  which could affect
its ability,  or that of any of its Subsidiaries,  to maintain such insurance or
bonding coverage;

<PAGE>A-39

        6.1.5 Perform  its  contractual  obligations and not breach or come into
default on any of such obligations,  and not amend,  modify,  or, except as they
may be  terminated  in  accordance  with their  terms,  terminate  any  material
contract,  agreement,  understanding,  commitment,  or offer, whether written or
oral,  (collectively referred to as an "Understanding") or materially default in
the performance of any of its  obligations  under any  Understanding  where such

acquisition  of the  assets of  Humboldt  other than in the  ordinary  course of
business;  or (d)  acquisition in excess of ten percent (10%) of the outstanding
capital  stock  of  Humboldt  other  than as  contemplated  by  this  Agreement.
Notwithstanding the foregoing, nothing contained in this Agreement shall prevent
Humboldt or its Board of Directors from (i) furnishing nonpublic information to,
or entering  into  discussions  or  negotiations  with,  any Person or entity in
connection with an unsolicited  bona fide written  Acquisition  Proposal by such
Person or entity,  or recommending an unsolicited bona fide written  Acquisition
Proposal to the shareholders of Humboldt, if and only to the extent that (A) the
Board of Directors of Humboldt has  determined and believes in good faith (after
consultation  with and the  concurrence  of its  financial  advisor)  that  such
Acquisition Proposal would, if consummated,  result in a transaction  materially
more favorable,  from a financial point of view, to Humboldt's shareholders than
the  transaction  contemplated  by  this  Agreement  (any  such  more  favorable
Acquisition Proposal being referred to in this Agreement as a "Humboldt Superior
Proposal") and Humboldt's Board of Directors has determined in good faith, after
consultation  with and based on written  advice from its outside legal  counsel,
that such action is necessary for Humboldt to comply with its  fiduciary  duties
to shareholders under applicable law, and (B) prior to furnishing such nonpublic
information to, or entering into  discussions or negotiations  with, such Person
or entity,  Humboldt's Board of Directors received from such Person or entity an
executed confidentiality  agreement,  with terms no more favorable to such party
than  those  contained  in the  Confidentiality  Agreement  between  Tehama  and
Humboldt,  or (ii) complying with Rule 14e-2  promulgated under the Exchange Act
with regard to an Acquisition Proposal, if such Rule is applicable thereto;

        6.4.13  Take   or   cause   to   be   taken   any   action  which  would
disqualify the Merger as a "reorganization" within the meaning of Section 368(a)
of the IRC as a tax-free reorganization;

<PAGE>A-49

        6.4.14  Take or  cause  to be  taken into OREO  any  commercial property
without an environmental report reporting no adverse environmental  condition on
such  property,  with a copy of such report  delivered to Tehama prior to taking
such property into OREO; or

        6.4.15  Take or cause to be  taken  any  action  which  would disqualify
the Merger from being accounted for on a "pooling of interest" basis; or

        6.4.16  Make  any new  elections  with  respect  to Taxes or any changes
in current  elections  with  respect  to Taxes  affecting  the  assets  owned by
Humboldt  or its  Subsidiaries.  Tehama  shall be  deemed to have  consented  in
writing to any election  Humboldt or its  Subsidiaries  shall desire to make if:
(i) the electing  Person  shall have  notified  the Chief  Executive  Officer of
Tehama in writing of its desire to make such election,  including in such notice
a reasonably complete summary of the election it desires to make and the reasons
it desires to make such election at least 20 Business Days prior to the due date
(including  extensions thereof) for filing such election;  and (ii) Tehama shall
not have  responded in writing to such notice by the fifth Business Day prior to
the due date (including extensions thereof) for filing such election.

        6.4.17   Humboldt  agrees  to  file  a  registration  statement  for  or
otherwise register with the Securities and Exchange Commission the stock options
of Tehama  outstanding  at the Closing and the related  common stock of Humboldt
promptly after the Closing.

reorganization within the meaning of Section 368(b) of the IRC;

of consummating such transactions; and

Tehama  Common Stock shall have  exercised  dissenters'  rights.  Dissenters  of

dissenters' rights.

Material  Adverse  Event shall have been caused in whole or in material  part by
any action or inaction within the control of Tehama or any of its  Subsidiaries,
or any of their  directors or executive  officers (it being  understood that any
breach or Default or Tehama Material  Adverse Event that occurred after the date
of this Agreement and was outside of the control of Tehama and its Subsidiaries,
and the  directors and executive  officers  thereof,  such as, by way of example

Fairness  Opinion;  or a  termination  of this  Agreement by Tehama  pursuant to
Section 8.1.4 (breach of representations  and warranties of Humboldt) or Section
8.1.6 (Default), or Section 8.1.9 (disclosure in Closing Schedules of a Humboldt
Material Adverse Event),  where such breach of  representation  or warranty,  or
such Default or Humboldt  Material Adverse Event shall have been caused in whole
or in material part by any action or inaction  within the control of Humboldt or
any of its  Subsidiaries,  or any of their  directors or executive  officers (it
being understood that any action or inaction outside of the control of Humboldt,
its Subsidiaries and their directors and executive officers,  such as, by way of
example only, the filing of a lawsuit  against  Humboldt,  shall not come within
this Section 8.5.3),  then, Humboldt shall pay to Tehama the sum of Five Hundred
Thousand Dollars ($500,000), in cash; provided,  however, that if an Acquisition
Event occurs  involving  Humboldt within one hundred eighty (180) days following
any  termination by Tehama to which this Section 8.5.3  applies,  Humboldt shall
pay to Tehama an additional Two Hundred Fifty Thousand Dollars ($250,000).

        8.5.4  The  parties have  determined  that  the occurrence of any of the
events or circumstances set forth in Sections 8.5.1, 8.5.2 and 8.5.3 would cause
a  substantial  damage  and loss and lost  business  opportunities  to the party
terminating   this   Agreement  as  a  result  thereof  and  that  the  payments
contemplated  by Sections  8.5.1,  8.5.2 and 8.5.3 above provide  reasonable and

<PAGE>A-56

fair compensation for such damage, loss and lost business  opportunities and are
not intended to be and do not constitute a penalty or forfeiture.  Such payments
will be made within 10 Business Days  following a  termination  of the Agreement
that gives rise to the payment of such liquidated  damages  pursuant to Sections
8.5.1,  8.5.2 or 8.5.3,  as applicable.  Upon the making and receipt of payments
due under this Section 8.5,  neither  party,  nor any  Affiliates  of any party,
shall have any further  obligation or liability of any kind under this Agreement
to the other party, except pursuant to Section 5.1.4, 5.5 and 9.5.

        8.5.5  In the  event  of the  termination of this  Agreement by Humboldt
or Tehama for any reason  other than as specified  in Sections  8.5.1,  8.5.2 or
8.5.3 above, none of the parties hereto, nor any Affiliates of any such parties,
shall have any further  obligation  or liability of any kind to the other party,
except pursuant to Sections 5.1.4, 5.5 and 9.5.

[Effective Date]

Members of the Board of Directors
Tehama Bancorp
239 S. Main Street
Red Bluff, CA 96080-0890

Members of the Board:


You have requested our opinion as investment bankers as to the fairness,  from a
financial point of view, to the shareholders of Tehama Bancorp ("Tehama") of the
Conversion  Ratio as  defined  in Section  2.1(a) of the  Agreement  and Plan of
Reorganization dated as of September 20, 2000 (the "Agreement"), in the proposed
merger  (the  "Merger")  of Humboldt  Bancorp  ("Humboldt")  and Tehama.  On the
Effective Time (as such term is defined in the Agreement),  each share of Tehama
Common  Stock  will be  converted  into the  right to  receive  1.775  shares of
Humboldt Common Stock subject to adjustment as defined in the Agreement.

In arriving at our opinion,  we have reviewed and analyzed,  among other things,
the following: (i) the Agreement;  (ii) certain publicly available financial and
other data with respect to Humboldt and Tehama, including consolidated financial
statements for recent years and interim periods to June 30, 2000;  (iii) certain
other publicly available financial and other information concerning Humboldt and
Tehama and the trading  markets for the publicly  traded  securities of Humboldt
and Tehama; (iv) publicly available information  concerning other banks and bank
holding  companies,  the trading markets for their securities and the nature and
terms of certain other merger  transactions we believed relevant to our inquiry;
and (v)  evaluations  and  analyses  prepared  and  presented  to the  Board  of
Directors of Tehama or a committee  thereof in  connection  with the Merger.  We
have held discussions with senior  management of Humboldt and Tehama  concerning
the companies' past and current operations, financial condition and prospects.

We have reviewed with the senior  management of Tehama earnings  projections for
Tehama as a stand-alone entity, assuming the Merger does not occur. We have also
reviewed with the management of Humboldt earnings  projections for Humboldt as a
stand-alone  entity,  assuming  the  Merger  does not occur.  Certain  financial
projections  for  the  combined   companies  and  for  Tehama  and  Humboldt  as
stand-alone entities were derived by us based partially upon the projections and
information  described above, as well as our own assessment of general economic,
market and financial conditions.

In conducting our review and in arriving at our opinion, we have relied upon and
assumed the accuracy and  completeness  of the financial  and other  information
provided to us or publicly available, and we have not assumed any responsibility
for  independent  verification  of the same. We have relied on advice of counsel
and independent accountants as to all legal and financial reporting matters with
respect to Humboldt,  Tehama, the Merger and the Agreement.  We have relied upon
the managements of Tehama and Humboldt as to the reasonableness of the financial
and operating  forecasts,  projections and projected operating cost savings (and
the  assumptions  and bases  therefor)  provided to us, and we have assumed that
such  forecasts,  projections  and projected  operating cost savings reflect the
best currently available estimates and judgments of the applicable  managements.

We have also assumed,  without assuming any  responsibility  for the independent
verification of same,  that the aggregate  allowances for loan losses for Tehama
and Humboldt are adequate to cover such losses. We have not made or obtained any
evaluations  or  appraisals  of the property of Tehama or Humboldt,  nor have we
examined any individual loan credit files. For purposes of this opinion, we have
assumed  that the  Merger  will  have  the tax,  accounting  and  legal  effects
(including,  without  limitation,  that the Merger  will be  accounted  for as a
pooling of  interests)  described  in the  Agreement.  Our opinion as  expressed
herein is  limited  to the  fairness,  from a  financial  point of view,  to the
holders of the Common Stock of Tehama of the Conversion  Ratio in the Merger and
does not address  Tehama's  underlying  business  decision  to proceed  with the
Merger.

We  have  considered  such  financial  and  other  factors  as  we  have  deemed
appropriate under the circumstances,  including among others the following:  (i)
the  historical  and current  financial  position and results of  operations  of
Tehama and Humboldt,  including interest income,  interest expense, net interest
income,  net interest margin,  provision for loan losses,  non-interest  income,
non-interest expense,  earnings,  dividends,  internal capital generation,  book
value,  intangible  assets,  return on assets,  return on shareholders'  equity,
capitalization,  the amount and type of non-performing  assets,  loan losses and
the reserve for loan losses,  all as set forth in the financial  statements  for
Tehama and for Humboldt; (ii) the assets and liabilities of Tehama and Humboldt,
including  the  loan,  investment  and  mortgage  portfolios,   deposits,  other
liabilities,  historical and current  liability sources and costs and liquidity;
and (iii) the nature and terms of certain  other merger  transactions  involving
banks and bank holding companies. We have also taken into account our assessment
of general economic, market and financial conditions and our experience in other
transactions,  as  well  as our  experience  in  securities  valuation  and  our
knowledge of the banking industry  generally.  Our opinion is necessarily  based
upon  conditions  as they exist and can be  evaluated on the date hereof and the
information made available to us through the date hereof.

It is  understood  that  this  letter  is for the  information  of the  Board of
Directors of Tehama.  This letter does not  constitute a  recommendation  to the
Board of Directors or to any  shareholder of Tehama with respect to any approval
of the Merger.  This  opinion is not to be quoted or referred to, in whole or in
part, in any registration  statement,  prospectus or proxy statement,  or in any
other document used in connection  with the offering or sale of securities,  nor
shall this  letter be used for any other  purposes,  without  our prior  written
consent, which consent is hereby granted.

Based upon and subject to the  foregoing,  we are of the  opinion as  investment
bankers that, as of the date hereof, the Conversion Ratio in the Merger is fair,
from a financial point of view, to the holders of the Common Stock of Tehama.


Very truly yours,

                                  [APPENDIX C]


August 17, 2000



Board of Directors
Humboldt Bancorp
701 Fifth Street
Eureka, CA  95501

Ladies & Gentlemen:

You have asked D.A. Davidson & Co.  ("Davidson") to provide this written opinion
as to the fairness to the holders of the  outstanding  shares of common stock of
Humboldt Bancorp, Eureka,  California,  ("Humboldt"),  from a financial point of
view, of the merger  consideration  (as  described  below) to be received by the
shareholders  of Tehama  Bancorp,  Red  Bluff,  California,  ("Tehama"),  in the
proposed  merger of Humboldt  and Tehama (the  "Merger")  as of the date of this
letter.

We understand  that Humboldt and Tehama will enter into an Agreement and Plan of
Merger  (the  "Agreement").  Pursuant to the  Agreement,  Tehama will merge into
Humboldt,  which will be the surviving  corporation.  One hundred percent of the
outstanding  common  stock  shares of Tehama  will be  converted  into shares of
common stock of Humboldt;  each outstanding share of Tehama common stock will be
exchanged for 1.775 shares of Humboldt  common stock, as more fully described in
the  Agreement,  and  subject to certain  adjustments  if the  Humboldt  Average
Trading Price is less than $9.84375.

Davidson,  as  part  of its  investment  banking  business,  is  engaged  in the
valuation of banking and other  businesses  and their  securities  in connection
with mergers and acquisitions,  negotiated underwritings,  competitive biddings,
secondary  distributions of listed and unlisted  securities,  private placements
and valuations for estate, corporate and other purposes. We make a market in the
common  stock of Humboldt  but do not publish a research  recommendation  on the
stock. We do not make a market in nor publish a research  recommendation  on the
stock of Tehama.  Davidson  will receive a fee for providing our opinion to you.
We have acted as financial  advisor to both  Humboldt  and Tehama in  connection
with both companies'  consideration of an investment in Central Pacific Mortgage
Company,  and we have acted as Humboldt's  financial advisor in connection with,
and have participated in certain negotiations leading to, the Agreement.

In connection with our opinion, we have, among other things:

1.   Evaluated  financial  and  operating  information  relating to Humboldt and
     Tehama including  without  limitation,  financial reports of both companies
     filed  with the SEC and other  regulatory  agencies  for the  fiscal  years
     ending December 31, 1998 and 1999 and for the periods ending March 31, 2000
     and June 30, 2000, and other internal operating reports and analyses, asset
     quality evaluations and related information;

2.   Reviewed the financial terms and conditions of the August 15, 2000 draft of
     the Agreement;

3.   Conducted   conversations  with   representatives  of  management  of  both
     companies regarding recent and projected financial  performance and certain
     other information regarding both companies furnished to us by them;

4.   Compared the financial  performance of both companies with those of certain
     other  companies  in the banking  industry in  California  and Oregon,  the
     western United States and the United States  generally,  which we deemed to
     be relevant;

5.   Considered  the  financial  terms,  to the extent  publicly  available,  of
     selected  business  combinations of companies in the banking industry which
     are deemed to be comparable, in whole or in part, to the Merger;

6.   Compared  the relative  contributions  of assets,  liabilities,  income and
     expenses to the  resulting  company in the merger to those of certain other
     companies  in the banking  industry in  California  and Oregon,  which have
     recently engaged in a merger transaction, which we deemed to be relevant;

7.   Made  inquiries  regarding  and  discussed the Merger and the Agreement and
     other related matters with Humboldt's counsel; and

8.   Performed such other analyses and examinations, as we deemed appropriate.

We have assumed and relied upon, without independent verification,  the accuracy
and  completeness  of the  information  provided to us by both companies for the
purpose of this opinion.  Additionally,  where appropriate,  we have relied upon
publicly  available  information  that we believe to be  reliable,  accurate and
complete; however, we cannot guarantee the reliability, accuracy or completeness
of  any  such  publicly  available   information.   We  have  also  assumed  the
reasonableness  of and relied upon the estimates and judgments of each company's
management  as  to  the  resulting   company's  future  business  and  financial
prospects. Our analysis and review is based upon there being no material changes
in either company's assets, financial condition, results of operation,  business
or prospects since the respective dates of their last financial  statements made
available to us. We have relied on advice of Humboldt's  counsel and independent
accountants as to all legal and financial  reporting matters with respect to the
Merger. We assume that the Merger will be completed in a manner that complies in
all respects with the  applicable  provisions of the  Securities Act of 1933, as
amended (the  "Securities  Act"),  the  Securities  Exchange Act of 1934 and all
other applicable federal and state statutes, rules and regulations.

We have not made an  independent  evaluation  of the  assets or  liabilities  of
Humboldt or Tehama, nor has either company furnished us with such appraisals. We
are not  experts  in the  evaluation  of loan  portfolios  for the  purposes  of
assessing  the  adequacy  of the  allowance  for loan and lease  losses and have
assumed that such  allowances  for each of the companies  are, in the aggregate,
adequate to cover such losses.

Our opinion is necessarily  based upon economic,  market and other conditions as
in effect on, and the  information  made  available to us as of August 17, 2000.
Events occurring after August 17, 2000 could  materially  affect the assumptions
used in preparing this opinion.

The preparation of an opinion  involves  various  determinations  as to the most
appropriate  and relevant  methods of financial  analysis and the application of
those methods to the particular circumstances. Consequently, this opinion is not
readily susceptible to partial analysis of summary  description.  Moreover,  the
evaluation of fairness, from a financial point of view, of the Exchange Ratio is
to some extent subjective, based on our experience and judgment, and not merely,
the  result  of  mathematical  analysis  of  financial  data.  Accordingly,  not
withstanding the separate factors summarized above, we believe that our analyses
must be considered as a whole and that selecting portions of our analysis and of
the factors  considered  by us,  without  considering  all analyses and factors,
could  create  an  incomplete  view of the  evaluation  process  underlying  our
opinion.

Our  opinion is  limited to the  fairness  of the merger  consideration,  from a
financial point of view, to the holders of Humboldt common stock. This letter is
intended for the benefit and sole use of the Humboldt Board of Directors and may
not be used for any purpose and is not a  recommendation  to any Humboldt common
stock holder as to how such holder  should vote with respect to the merger.  Our
opinion does not address the  underlying  business  decision to proceed with the
merger.  This opinion may not be used or referred to by  Humboldt,  or quoted or
disclosed to any person in any manner,  without  prior  written  consent,  which
consent  is hereby  given to the  inclusion  of this  opinion  in a joint  proxy
statement/prospectus  filed  with the  Securities  and  Exchange  Commission  in
connection with the Merger. In furnishing this opinion,  we do not admit that we
are experts  within the meaning of the term  "experts" as used in the Securities
Act and the rules and regulations promulgated  thereunder,  nor do we admit that
this opinion  constitutes a report or valuation within the meaning of Section 11
of the Securities Act.

We are not expressing an opinion  regarding the price at which  Humboldt's stock
may trade at any future time after the date of this letter.

Based upon the foregoing and other such matters we have deemed  relevant,  it is
our opinion, as of August 17, 2000 that the merger  consideration  including the
exchange ratio of 1.775 which will be used to exchange Tehama common shares into
shares of Humboldt  common stock as specified in the  Agreement is fair,  from a
financial point of view, to the common stock holders of Humboldt.

Very truly yours,

D.A. Davidson & Co.

                                   Appendix D
                       California General Corporation Law
                         Chapter 13. Dissenters' Rights


SECTION 1300. RIGHT TO REQUIRE  PURCHASE -- "DISSENTING  SHARES" AND "DISSENTING
SHAREHOLDER" DEFINED.

     (a)  If  the  approval  of  the  outstanding  shares  (Section  152)  of  a
corporation is required for a reorganization  under  subdivisions (a) and (b) or
subdivision  (e) or (f) of Section 1201,  each  shareholder  of the  corporation
entitled  to  vote on the  transaction  and  each  shareholder  of a  subsidiary
corporation in a short-form merger may, by complying with this chapter,  require
the  corporation in which the  shareholder  holds shares to purchase for cash at
their fair market value the shares owned by the shareholder which are dissenting
shares as defined in subdivision  (b). The fair market value shall be determined
as of the day  before  the  first  announcement  of the  terms  of the  proposed
reorganization or short-form merger,  excluding any appreciation or depreciation
in consequence of the proposed action, but adjusted for any stock split, reverse
stock split or share dividend which becomes effective thereafter.

     (b) As used in this  chapter,  "dissenting  shares" means shares which come
within all of the following descriptions:

        (1) Which were not immediately prior to the reorganization or short-form
merger either (A) listed on any national  securities  exchange  certified by the
Commissioner  of  Corporations  under  subdivision  (o) of Section  25100 or (B)
listed on the list of OTC margin  stocks issued by the Board of Governors of the
Federal  Reserve  System,  and the notice of meeting of shareholders to act upon
the  reorganization  summarizes  this section and Sections 1301,  1302, 1303 and
1304; provided,  however,  that this provision does not apply to any shares with
respect  to which  there  exists  any  restriction  on  transfer  imposed by the
corporation  or by any law or  regulation;  and  provided,  further,  that  this
provision does not apply to any class of shares described in subparagraph (A) or
(B) if demands for  payment  are filed with  respect to 5 percent or more of the
outstanding shares of that class.

        (2)  Which  were  outstanding  on  the  date  for  the  determination of
shareholders  entitled to vote on the  reorganization  and (A) were not voted in
favor of the  reorganization  or, (B) if described in subparagraph (A) or (B) of
paragraph  (1) (without  regard to the provisos in that  paragraph),  were voted
against the  reorganization,  or which were held of record on the effective date
of a short-form  merger;  provided,  however,  that subparagraph (A) rather than
subparagraph  (B) of this  paragraph  applies  in any case  where  the  approval
required by Section 1201 is sought by written consent rather than at a meeting.

        (3)  Which  the dissenting shareholder has demanded that the corporation
purchase at their fair market  value,  in  accordance  with Section 1301.

        (4)  Which the dissenting shareholder has submitted for endorsement, in
accordance with Section 1302.

     (c)  As  used  in  this  chapter,   "dissenting   shareholder"   means  the
recordholder of dissenting shares and includes a transferee of record.

SECTION 1301. DEMAND FOR PURCHASE.

     (a) If, in the case of a reorganization,  any shareholders of a corporation
have a right under Section 1300,  subject to compliance  with paragraphs (3) and
(4) of  subdivision  (b) thereof,  to require the  corporation to purchase their
shares for cash, such  corporation  shall mail to each such shareholder a notice
of the approval of the  reorganization  by its outstanding  shares (Section 152)
within  10  days  after  the  date of such  approval,  accompanied  by a copy of
Sections  1300,  1302,  1303,  1304 and this  section,  a statement of the price
determined  by the  corporation  to  represent  the  fair  market  value  of the
dissenting  shares,  and a brief  description of the procedure to be followed if
the shareholder desires to exercise the shareholder's right under such sections.
The statement of price  constitutes  an offer by the  corporation to purchase at
the price stated any dissenting  shares as defined in subdivision (b) of Section
1300, unless they lose their status as dissenting shares under Section 1309.

     (b) Any  shareholder who has a right to require the corporation to purchase
the shareholder's shares for cash under Section 1300, subject to compliance with
paragraphs  (3)  and  (4) of  subdivision  (b)  thereof,  and  who  desires  the
corporation  to  purchase  such  shares  shall  make  written  demand  upon  the
corporation  for the purchase of such shares and payment to the  shareholder  in
cash of their fair market  value.  The demand is not  effective  for any purpose
unless it is received by the  corporation  or any transfer  agent thereof (1) in
the  case  of  shares  described  in  clause  (i) or (ii)  of  paragraph  (1) of
subdivision  (b) of  Section  1300  (without  regard  to the  provisos  in  that
paragraph),  not later than the date of the  shareholders'  meeting to vote upon
the  reorganization,  or (2) in any other case  within 30 days after the date on
which  the  notice  of  the  approval  by the  outstanding  shares  pursuant  to
subdivision  (a) or the notice  pursuant to subdivision  (i) of Section 1110 was
mailed to the shareholder.

     (c) The demand  shall  state the  number  and class of the  shares  held of
record by the  shareholder  which the  shareholder  demands that the corporation
purchase and shall contain a statement of what such shareholder claims to be the
fair market value of those shares as of the day before the  announcement  of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.

SECTION 1302. ENDORSEMENT OF SHARES.

     Within  30 days  after  the date on which  notice  of the  approval  by the
outstanding shares or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the  shareholder,  the shareholder  shall submit to the corporation at
its principal office or at the office of any transfer agent thereof,  (a) if the
shares are certificated securities,  the shareholder's certificates representing
any shares which the shareholder  demands that the corporation  purchase,  to be
stamped or endorsed with a statement that the shares are dissenting shares or to
be exchanged for certificates of appropriate denomination so stamped or endorsed
or (b) if the shares are uncertificated securities, written notice of the number
of shares which the  shareholder  demands that the  corporation  purchase.  Upon
subsequent  transfers of the dissenting  shares on the books of the corporation,
the  new  certificates,   initial  transaction  statement,   and  other  written
statements  issued therefor shall bear a like statement,  together with the name
of the original dissenting holder of the shares.

<PAGE>D-3

SECTION 1303. AGREED PRICE -- TIME FOR PAYMENT.

     (a) If the  corporation  and the  shareholder  agree  that the  shares  are
dissenting  shares  and  agree  upon the  price of the  shares,  the  dissenting
shareholder  is entitled to the agreed price with interest  thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the fair
market value of any dissenting shares as between the corporation and the holders
thereof shall be filed with the secretary of the corporation.

     (b) Subject to the  provisions of Section 1306,  payment of the fair market
value of dissenting shares shall be made within 30 days after the amount thereof
has been agreed or within 30 days after any statutory or contractual  conditions
to the  reorganization  are  satisfied,  whichever is later,  and in the case of
certificated  securities,  subject to  surrender of the  certificates  therefor,
unless provided otherwise by agreement.

SECTION 1304. DISSENTER'S ACTION TO ENFORCE PAYMENT.

     (a) If the corporation denies that the shares are dissenting shares, or the
corporation and the shareholder  fail to agree upon the fair market value of the
shares,  then the  shareholder  demanding  purchase of such shares as dissenting
shares or any interested corporation,  within six months after the date on which
notice  of the  approval  by the  outstanding  shares  (Section  152) or  notice
pursuant to subdivision (i) of Section 1110 was mailed to the  shareholder,  but
not thereafter,  may file a complaint in the superior court of the proper county
praying the court to determine  whether the shares are dissenting  shares or the
fair  market  value of the  dissenting  shares or both or may  intervene  in any
action pending on such a complaint.

     (b) Two or more dissenting shareholders may join as plaintiffs or be joined
as  defendants  in  any  such  action  and  two  or  more  such  actions  may be
consolidated.

     (c) On the trial of the action,  the court shall  determine the issues.  If
the status of the shares as dissenting shares is in issue, the court shall first
determine that issue.  If the fair market value of the  dissenting  shares is in
issue,  the  court  shall  determine,  or shall  appoint  one or more  impartial
appraisers to determine, the fair market value of the shares.

SECTION 1305. APPRAISERS' REPORT -- PAYMENT -- COSTS.

     (a) If the court  appoints an appraiser or  appraisers,  they shall proceed
forthwith to determine the fair market value per share. Within the time fixed by
the court,  the appraisers,  or a majority of them, shall make and file a report
in the office of the clerk of the court.  Thereupon, on the motion of any party,
the report shall be submitted to the court and  considered  on such  evidence as
the court  considers  relevant.  If the court finds the report  reasonable,  the
court may confirm it.

     (b) If a  majority  of the  appraisers  appointed  fail to make  and file a
report within 10 days from the date of their  appointment or within such further
time as may be allowed by the court or the report is not confirmed by the court,
the court shall determine the fair market value of the dissenting shares.

     (c) Subject to the  provisions of Section 1306,  judgment shall be rendered
against the  corporation for payment of an amount equal to the fair market value
of each dissenting share multiplied by the number of dissenting shares which any
dissenting  shareholder  who  is a  party, or who has intervened, is entitled to

<PAGE>D-4

require the  corporation  to purchase,  with interest  thereon at the legal rate
from the date on which judgment was entered.

     (d)  Any  such  judgment  shall  be  payable   forthwith  with  respect  to
uncertificated  securities  and, with respect to certificated  securities,  only
upon the endorsement and delivery to the corporation of the certificates for the
shares described in the judgment. Any party may appeal from the judgment.

     (e) The  costs of the  action,  including  reasonable  compensation  to the
appraisers  to be fixed by the court,  shall be assessed or  apportioned  as the
court considers  equitable,  but, if the appraisal  exceeds the price offered by
the  corporation,  the  corporation  shall  pay  the  costs  (including  in  the
discretion of the court  attorneys'  fees, fees of expert witnesses and interest
at the legal rate on judgments  from the date of compliance  with Sections 1300,
1301 and 1302 if the value  awarded by the court for the shares is more than 125
percent of the price offered by the corporation under subdivision (a) of Section
1301).

SECTION 1306. DISSENTING SHAREHOLDER'S STATUS AS CREDITOR.

     To the extent that the  provisions  of Chapter 5 prevent the payment to any
holders of  dissenting  shares of their fair  market  value,  they shall  become
creditors of the  corporation  for the amount thereof  together with interest at
the legal rate on judgments  until the date of payment,  but  subordinate to all
other  creditors  in any  liquidation  proceeding,  such debt to be payable when
permissible under the provisions of Chapter 5.

SECTION 1307. DIVIDENDS PAID AS CREDIT AGAINST PAYMENT.

     Cash  dividends  declared and paid by the  corporation  upon the dissenting
shares  after the date of  approval  of the  reorganization  by the  outstanding
shares  (Section  152) and prior to payment  for the  shares by the  corporation
shall  be  credited  against  the  total  amount  to be paid by the  corporation
therefor.

SECTION 1308. CONTINUING RIGHTS AND PRIVILEGES OF DISSENTING SHAREHOLDERS.

     Except as expressly  limited in this chapter,  holders of dissenting shares
continue to have all the rights and privileges  incident to their shares,  until
the fair market value of their shares is agreed upon or determined. A dissenting
shareholder  may not  withdraw  a demand  for  payment  unless  the  corporation
consents thereto.

SECTION 1309. TERMINATION OF DISSENTING SHAREHOLDER STATUS.

     Dissenting  shares lose their status as  dissenting  shares and the holders
thereof cease to be dissenting  shareholders and cease to be entitled to require
the  corporation  to  purchase  their  shares upon the  happening  of any of the
following:

     (a) The corporation  abandons the  reorganization.  Upon abandonment of the
reorganization,   the  corporation   shall  pay  on  demand  to  any  dissenting
shareholder  who has initiated  proceedings in good faith under this chapter all
necessary expenses incurred in such proceedings and reasonable attorneys' fees.

     (b) The shares are transferred prior to their submission for endorsement in
accordance  with Section 1302 or are  surrendered  for conversion into shares of
another class in accordance with the articles.

<PAGE>D-5

     (c) The dissenting  shareholder  and the  corporation do not agree upon the
status of the  shares as  dissenting  shares or upon the  purchase  price of the
shares,  and neither  files a complaint  or  intervenes  in a pending  action as
provided in Section  1304,  within six months  after the date on which notice of
the approval by the outstanding  shares or notice pursuant to subdivision (i) of
Section 1110 was mailed to the shareholder.

     (d) The  dissenting  shareholder,  with  the  consent  of the  corporation,
withdraws the shareholder's demand for purchase of the dissenting shares.

SECTION 1310. SUSPENSION OF PROCEEDINGS FOR PAYMENT PENDING LITIGATION.

     If litigation is  instituted to test the  sufficiency  or regularity of the
votes of the shareholders in authorizing a reorganization, any proceedings under
Section  1304 and 1305 shall be  suspended  until  final  determination  of such
litigation.

SECTION 1311. EXEMPT SHARES.

     This  chapter,  except  Section  1312,  does not apply to classes of shares
whose  terms and  provisions  specifically  set  forth the  amount to be paid in
respect to such shares in the event of a reorganization or merger.

SECTION 1312. ATTACKING VALIDITY OF REORGANIZATION OR MERGER.

     (a) No shareholder  of a corporation  who has a right under this chapter to
demand  payment of cash for the shares  held by the  shareholder  shall have any
right at law or in  equity to  attack  the  validity  of the  reorganization  or
short-form  merger, or to have the reorganization or short-form merger set aside
or rescinded,  except in an action to test whether the number of shares required
to authorize  or approve the  reorganization  have been  legally  voted in favor
thereof;  but any  holder  of  shares  of a class  whose  terms  and  provisions
specifically  set forth the amount to be paid in respect to them in the event of
a reorganization  or short-form merger is entitled to payment in accordance with
those terms and provisions or, if the principal terms of the  reorganization are
approved  pursuant to subdivision (b) of Section 1202, is entitled to payment in
accordance with the terms and provisions of the approved reorganization.

     (b) If one of the  parties  to a  reorganization  or  short-form  merger is
directly or indirectly  controlled  by, or under common  control  with,  another
party to the  reorganization  or short-form  merger,  subdivision  (a) shall not
apply to any shareholder of such party who has not demanded  payment of cash for
such  shareholder's  shares  pursuant to this  chapter;  but if the  shareholder
institutes any action to attack the validity of the reorganization or short-form
merger  or to  have  the  reorganization  or  short-form  merger  set  aside  or
rescinded, the shareholder shall not thereafter have any right to demand payment
of cash for the shareholder's  shares pursuant to this chapter. The court in any
action attacking the validity of the  reorganization  or short-form merger or to
have the  reorganization  or short-form  merger set aside or rescinded shall not
restrain  or enjoin the  consummation  of the  transaction  except upon 10 days'
prior  notice to the  corporation  and upon a  determination  by the court  that
clearly no other remedy shall adequately protect the complaining  shareholder or
the class of shareholders of which such shareholder is a member.

     (c) If one of the  parties  to a  reorganization  or  short-form  merger is
directly or indirectly  controlled  by, or under common  control  with,  another
party  to the  reorganization or  short-form merger, in any action to attack the

<PAGE>D-6

validity  of  the   reorganization   or   short-form   merger  or  to  have  the
reorganization  or short-form  merger set aside or  rescinded,  (1) a party to a
reorganization  or  short-form  merger  which  controls  another  party  to  the
reorganization  or  short-form  merger shall have the burden of proving that the
transaction  is just and  reasonable as to the  shareholders  of the  controlled
party,  and (2) a person who controls  two or more  parties to a  reorganization
shall have the burden of proving that the  transaction is just and reasonable as
to the shareholders of any party so controlled.

                                     PART II


ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Articles of  Incorporation  and Bylaws of Humboldt  Bancorp provide for
indemnification  of agents  including  directors,  officers and employees to the
maximum  extent  allowed by  California  law  including  the use of an indemnity
agreement.  Humboldt  Bancorp's  Articles further provide for the elimination of
director  liability  for  monetary  damages  to the  maximum  extent  allowed by
California  law. The  indemnification  law of the State of California  generally
allows indemnification in matters not involving the right of the corporation, to
an agent of the  corporation  if such person acted in good faith and in a manner
such person reasonably  believed to be in the best interests of the corporation,
and in the case of a criminal  matter,  had no  reasonable  cause to believe the
conduct of such person was  unlawful.  California  law,  with respect to matters
involving the right of a corporation,  allows indemnification of an agent of the
corporation,  if such  person  acted  in good  faith,  in a manner  such  person
believed to be in the best interests of the  corporation  and its  shareholders;
provided that there will be no indemnification for: (i) amounts paid in settling
or otherwise disposing of a pending action without court approval; (ii) expenses
incurred in defending a pending action which is settled or otherwise disposed of
without  court  approval;  (iii)  matters  in which such  person  will have been
adjudged to be liable to the corporation  unless and only to the extent that the
court in which the  proceeding is or was pending will determine that such person
is entitled to be indemnified; or (iv) other matters specified in the California
General Corporation Law.

     Humboldt Bancorp's Bylaws provide that Humboldt Bancorp will to the maximum
extent permitted by law have the power to indemnify its directors,  officers and
employees.  Humboldt  Bancorp's  Bylaws also provide that Humboldt  Bancorp will
have the power to  purchase  and  maintain  insurance  covering  its  directors,
officers and employees  against any liability  asserted  against any of them and
incurred by any of them, whether or not Humboldt Bancorp would have the power to
indemnify them against such liability  under the provisions of applicable law or
the provisions of Humboldt  Bancorp's  Bylaws.  Certain  directors and executive
officers   of   Humboldt   Bancorp's   subsidiary,   Humboldt   Bank,   have  an
indemnification  agreement  with  Humboldt Bank that provides that Humboldt Bank
will  indemnify  such person to the full  extent  authorized  by the  applicable
provisions of California law, subject to federal banking law.

ITEM 22.  UNDERTAKINGS

     The undersigned Registrant hereby undertakes:

     To file,  during  any  period in which  offers or sales are being  made,  a
post-effective amendment to this Registration Statement:

     (a)  to  include  any  prospectus  required  by  Section  10(a)(3)  of  the
Securities Act of 1933;

     (b) to  reflect in the  prospectus  any facts or events  arising  after the
effective date of the Registration  Statement (or the most recent post-effective
amendment  thereof)  which,  individually  or  in  the  aggregate,  represent  a
fundamental  change in the information set forth in the Registration  Statement;
Notwithstanding the foregoing,  any increase or decrease in volume of securities
offered (if the total dollar value of  securities  offered would not exceed that
which  was  registered)  and any  deviation  from  the  low or  high  end of the
estimated  maximum  offering  range may be reflected  in the form of  prospectus
filed with the  Commission  pursuant  to Rule 424(b) if, in the  aggregate,  the
changes in volume and price  represent  no more that a 20% change in the maximum
aggregate  offering price set forth in the Calculation of Registration Fee table
in the effective registration statement;

     (c) to  include  any  material  information  with  respect  to the  plan of
distribution  not  previously  disclosed  in the  Registration  Statement or any
material change to such information in the Registration Statement;

     provided,  however,  that paragraphs (1)(i) and (1)(ii) do not apply if the
Registration Statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a  post-effective  amendment by those  paragraphs  is
contained in periodic reports filed by the Registrant  pursuant to Section 13 or
Section 15(d) of the Securities  Exchange Act of 1934 that are  incorporated  by
reference in the Registration Statement.

     That, for the purpose of determining any liability under the Securities Act
of  1933,  each  such  post-effective  amendment  will  be  deemed  to  be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities  at that time will be deemed to be the initial bona
fide offering thereof.

<PAGE>II-4

     To remove from  registration by means of a post-effective  amendment any of
the securities  being  registered  which remain unsold at the termination of the
offering.

     The undersigned  Registrant hereby undertakes as follows: that prior to any
public  reoffering  of the  securities  registered  hereunder  through  use of a
prospectus with is part of the  registration  statement,  by any person or party
who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer
undertakes that such reoffering  prospectus will contain the information  called
for by the applicable  registration  form with respect to reofferings by persons
who may be deemed underwriters, in addition to the information called for by the
other items of the applicable form.

     The Registrant undertakes that every prospectus: (i) that is filed pursuant
to the  paragraph  immediately  preceding,  or (ii)  that  purports  to meet the
requirements  of Section  10(a)(3) of the Act and is used in connection  with an
offering  of  securities  subject  to Rule  415,  will be  filed as a part of an
amendment  to the  registration  statement  and  will  not be  used  until  such
amendment is  effective,  and that,  for purposes of  determining  any liability
under the Securities  Act of 1933,  each such  post-effective  amendment will be
deemed to be a new  registration  statement  relating to the securities  offered
therein,  and the offering of such  securities at that time will be deemed to be
the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors,  officers and controlling  persons of the
Registrant pursuant to the foregoing  provisions,  or otherwise,  the Registrant
has been advised that in the opinion of the Securities  and Exchange  Commission
such  indemnification  is against  public policy as expressed in the Act and is,
therefore,  unenforceable. In the event that a claim for indemnification against
such liabilities  (other than the payment by the Registrant of expenses incurred
or paid by a director,  officer or  controlling  person of the Registrant in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.

     The  undersigned  registrant  hereby  undertakes  to  supply  by means of a
post-effective  amendment  all  information  concerning a  transaction,  and the
company  being  acquired  involved  therein,  that  was not the  subject  of and
included in the registration statement when it became effective.
