Item 5.  Other Events

On November  14,  1997,  SierraWest  Bancorp  ("SWB") and  California  Community
Bancshares  Corporation  ("CCBC")  issued a joint press release  announcing that
they  have  signed a  definitive  agreement  under  which SWB will  acquire  the
outstanding  common stock of CCBC in a transaction  valued at approximately  $39
million, based on the closing price of SWB stock on November 13, 1997. CCBC, the
parent of Continental  Pacific Bank, is headquartered in Vacaville,  California.
Continental  Pacific Bank operates  eight  banking  offices in Solano and Contra
Costa counties in California. CCBC had total assets of $192 million at September
30, 1997. The merger, which is scheduled to close during the first half of 1998,
is subject to the  approval  of CCBC's and SWB's  shareholders  and  federal and
state regulators, as well as certain other terms and conditions.

Under the terms of the proposed  transaction,  shareholders of CCBC will receive
shares of SWB common stock at an exchange  ratio to be  determined  by a formula
prior to the  effective  date of the  transaction,  based on the  average of the
closing prices of SWB common stock during a defined 20-day period.  For example,
if the average price during the 20-day period were $28.75,  the closing price of
SWB stock on November 13, 1997,  each share of CCBC stock would be exchanged for
approximately 0.9957 shares of SWB common stock. This transaction is expected to
be accounted for under the pooling of interests accounting method.

Continental  Pacific  Bank  ("CPB"),  a  California  state  banking  corporation
(collectively "CCBC").

WITNESSETH:

         A. The Boards of Directors of Sierra and CCBC deem it advisable  and in
the best interests of Sierra,  CCBC and their  shareholders that Sierra and CCBC

to be filed with the California Secretary of State and the Delaware Secretary of
State ("Agreement and Plan of Merger") and the Bank Merger Agreement attached as
Exhibit B is intended to be filed with the California Secretary of State when it
has been approved by the  Department of Financial  Institutions  of the State of
California ("Bank Merger Agreement"), (collectively the "Merger Agreements").

         C. The  Merger is  intended  to  qualify  as a tax free  reorganization
within the meaning of the provisions of Section 368 of the Internal Revenue Code
of 1986, as amended (the "IRC") and to qualify as a "pooling of interests".

         D. Pursuant to the Merger, each Bancshares shareholder will receive, in

         NOW,  THEREFORE,  in  consideration  of the  premises  and  the  mutual

mixed) and choses in action,  as they exist as of the Effective Date,  including
appointments,  designations  and nominations and all other rights and interests,
shall  pass  and be  transferred  to  and  vest  in  Bancorp  as  the  Surviving
Corporation  by virtue of the Merger on the  Effective  Date  without  any deed,

and the  corporate  existence  of Bancorp  as the  Surviving  Corporation  shall
continue unaffected and unimpaired by the merger; and the Surviving  Corporation

shall be  subject  to all of their  duties  and  liabilities  of every  kind and
description.  The Surviving  Corporation shall be responsible and liable for all
the liabilities and obligations of each of Bancorp and Bancshares; and any claim
existing or action or proceeding pending by or against Bancorp or Bancshares may
be prosecuted as if the Merger had not taken place, or the Surviving Corporation
may be substituted  in its place.  Neither the rights of creditors nor any liens
upon the property of Sierra,  Bancorp or Bancshares  shall be impaired by reason
of the Merger. The articles of incorporation of Bancorp shall be the articles of
incorporation  of the Surviving  Corporation  and the bylaws of Bancorp shall be
the bylaws of the Surviving  Bank. On the Effective  Date,  Bancorp shall assume
the operations of, as successor to,  Bancshares.  Subject to Section 1.4, on the
Effective  Date the board of directors  of Bancorp will  continue to serve until
successors  are  duly  elected  and  qualified.   Sierra  Bank  shall  remain  a
wholly-owned subsidiary of Bancorp.

         1.4  Board  Composition  After  the  Merger.  As  soon  as  practicable
following the Effective  Date,  the Boards of Directors of Bancorp and of Sierra
Bank shall appoint two existing  directors of  Bancshares,  Mr. Bernard E. Moore
and Mr.  Walter D.  Sunderman,  to the Boards of Directors of Bancorp and Sierra
Bank.  In the event Mr. Moore  and/or Mr.  Sunderman  (each a "CCBC  Appointee")
resigns or chooses not to serve as a director  of Bancorp  and/or  Sierra  Bank,
such CCBC  Appointee  shall  recommend his successor from those persons who were
directors  of  CCBC  on the  Effective  Date  (a  "Successor  Director")  to the
Nominating  Committee  of the Bancorp  Board of  Directors.  Assuming  that such
recommended  Successor  Director  meets the then existing  written  criteria for
selection  of  board  nominees,  the  recommended  Successor  Director  will  be
appointed to the Boards of  Directors of Bancorp and Sierra Bank.  If because of
death, disability,  or otherwise,  either Mr. Moore or Sunderman is incapable of
selecting his successor,  then the remaining CCBC Appointee  shall recommend the
Successor Director for the CCBC Appointee who is so incapacitated.  In the event
that any Successor  Director resigns,  chooses not to serve, or otherwise cannot
serve, then Bancorp shall have no further obligation to offer any other existing
director a position on  Bancorp's or Sierra  Bank's  Boards of  Directors.  Once
appointed to the Boards,  subject to the written performance criteria applicable
to all Bancorp directors, the nominating committee of Bancorp shall nominate and
recommend for approval such CCBC Appointee (or a Successor Director thereof) for
one year terms at the annual  meetings of Bancorp  for the years 1998,  1999 and
2000;  provided,  however,  if  any  such  director  is  not  re-elected  by the
shareholders  of  Bancorp,  then  Bancorp  shall have no further  obligation  to
further  nominate or appoint such director to the Boards of Directors of Bancorp
or Sierra Bank and shall have no further  obligation to offer any other existing
director a position on Bancorp's or Sierra Bank's  Boards of  Directors.  In the
event of a change of control of Bancorp  occurs in which the  acquirer  elects a
majority of the Board of Directors,  then the  requirements  of this Section 1.4
shall cease.

Section 2.  CONVERSION AND CANCELLATION OF SHARES.

         2.1  Exchange Amount; Conversion of Shares of Bancshares Common Stock.

          (a) For  purposes  of  this  Agreement,  capitalized  terms  have  the
              following meanings:

CCBC Shares                       Issued and outstanding shares of Bancshares 
                                  $0.10 par value common stock ("CCBC Shares")
                                  as of the Effective Date.

                                  or  subsidiary,  sale or  purchase of a
                                  substantial portion of any entity's assets, or
                                  tender offer or other means of  acquisition of
                                  substantially  all  the  outstanding   capital
                                  stock of any entity.

Exchange Ratio                    The  number  of  Sierra  Shares  to  be
                                  received  in  exchange  for  each  CCBC  Share
                                  pursuant  to  the  calculation  set  forth  in
                                  Section 2.1(b) below.

Market Value                      The average of the closing prices of the
                                  Sierra  Shares  as  reported  in  the  western
                                  edition of the Wall Street  Journal for the 20
                                  trading days preceding the Determination Date.
                                  For purpose of  determining  the average,  the
                                  divisor  shall be only  those  days on which a
                                  trade occurs.

Determination Date                The fifth business day preceding the Effective
                                  Date.

         (b) On the  Effective  Date,  by virtue of the Merger and  without  any
action on the part of the holders of CCBC Shares,  each  outstanding  CCBC Share
(other than any shares as to which dissenters' rights have been perfected) shall
be converted into the right to receive shares of the common stock, no par value,
of Bancorp  ("Sierra  common  stock" or "Sierra  Shares")  equal to the Exchange
Ratio as follows:

                  (i)  If the  Market  Value is between  $22.76 and  $25.24,
                       inclusive,  the Exchange Ratio shall be determined by
                       dividing $26.40 by the Market Value.

                  (ii) If the  Market  Value is between  $25.25 and  $26.25,
                       inclusive, the Exchange Ratio shall be 1.0476.

                  (iii)If the  Market  Value  is  between  $26.26  and  28.24,
                       inclusive,  the  Exchange  Ratio shall be 1.0476  minus
                       .000238  for each  $0.01 by which the  Market  Value is
                       greater than $26.25.

                  (iv) If the Market Value is $28.25, the Exchange Ratio shall
                       be 1.000.

                  (v)  Subject to the  limitations  set forth in Section  2.1(c)
                       below,  if the Market Value is between $28.26 and $29.25,
                       inclusive,  the  Exchange  Ratio shall be  determined  by
                       dividing  (A) $28.25  plus 75% of the amount by which the
                       Market Value exceeds $28.25 by (B) the Market Value.

                  (vi) Subject to the  limitations  set forth in Section  2.1(c)
                       below,  if the Market Value is between $29.26 and $30.25,
                       inclusive,  the  Exchange  Ratio shall be  determined  by
                       dividing  (A) $29.00  plus 50% of the amount by which the
                       Market Value exceeds $29.25 by (B) the Market Value.

                  (vii)Subject to the  limitations  set forth in Section  2.1(c)
                       below, if the Market Value exceeds  $30.26,  the Exchange
                       Ratio shall be determined by dividing (A) $29.50 plus 25%
                       of the amount by which the Market Value exceeds $30.25 by
                       (B) the Market Value.

                  (viii)Subject to the  limitations  set forth in Section 2.1(d)
                       below,  if the  Market  Value  is  $22.75  or  less,  the
                       Exchange Ratio shall be 1.1579.

         (c) In the event that Sierra  enters into a Business  Combination  with
any  other  entity in which  Sierra  shall not be the  continuing  or  surviving
corporation or entity of such Business  Combination  prior to the  Determination
Date,  then,  in the event that the Market Value  exceeds  $28.25,  the Exchange
Ratio shall be 1.000.

         (d) In the event that the Market Value is less than  $21.59,  then CCBC
has the right to terminate this Agreement pursuant to the terms of Section 11(h)
hereof.  If CCBC  notifies  Sierra that it intends to terminate  this  Agreement
pursuant to the  provisions of Section  11(h),  then Sierra shall have the right
but not the  obligation to elect to issue an additional  number of Sierra Shares
so that the Exchange  Ratio shall be equal to the quotient  obtained by dividing
$25.00 by the Market Value. If Sierra chooses not to exercise its right to issue
such additional Sierra Shares, then CCBC may proceed to terminate this Agreement
pursuant to Section 11(h).

         (e) On the Effective Date each  outstanding  Bancshares  debenture,  as
defined in Section  4.4,  shall be by virtue of the Merger,  assumed by Bancorp,
provided,  however,  the conversion of such  Bancshares  debentures  into Sierra
Shares shall be adjusted to reflect the Exchange Ratio on the Effective Date.

         (f) All  references in this Agreement to Sierra Shares or Sierra common
stock shall be deemed to include the corresponding  rights to purchase shares of
Sierra  common  stock,  including  common stock  equivalent  preferred  stock of
Bancorp,  pursuant to that Rights Agreement dated as of January 16, 1996 between
American  Stock  Transfer  and Trust  Company  and Sierra  Tahoe  Bancorp.  Each
certificate  representing  Sierra Shares will bear a notation  incorporating the
Rights Agreement by reference.

         2.2 Fractional Shares.  Notwithstanding  any other provision hereof, no
fractional  shares of Sierra  common  stock  shall be issued to  holders of CCBC
Shares.  In lieu thereof,  each such holder entitled to a fraction of a share of
Sierra common stock shall receive,  at the time of surrender of the  certificate
or certificates  representing such holder's CCBC Shares, an amount in cash equal
to the Market Value per share of the common stock of Sierra,  multiplied  by the
fraction of a share of Sierra common stock to which such holder  otherwise would
be  entitled.  No such holder  shall be entitled to  dividends,  voting  rights,
interest on the value of, or any other rights in respect of a fractional share.

         2.3  Surrender of CCBC Shares.

         (a) Prior to the Effective Date, Sierra shall appoint any bank or trust
company  mutually  acceptable to Bancshares  and Sierra,  as exchange agent (the
"Exchange  Agent") for the purpose of exchanging  certificates  representing the
CCBC Shares at and after the Effective  Date,  Sierra shall issue and deliver to
the Exchange Agent  certificates  representing  the Sierra  Shares,  as shall be
required to be delivered to holders of CCBC Shares. As soon as practicable after
the Effective  Date,  each holder of CCBC Shares  converted  pursuant to Section
2.1, upon surrender to the Exchange Agent of one or more  certificates  for such
CCBC  Shares  for  cancellation,  will be  entitled  to  receive  a  certificate
representing  the number of Sierra Shares  determined in accordance with Section
2.1 and a payment in cash with respect to fractional shares, if any,  determined
in accordance with Section 2.2.

         (b) No dividends or other  distributions of any kind which are declared
payable to  stockholders of record of the Sierra Shares after the Effective Date
will be paid to persons entitled to receive such  certificates for Sierra Shares
until such persons surrender their certificates  representing CCBC Shares.  Upon
surrender of such certificate representing CCBC Shares, the holder thereof shall
be paid, without interest,  any dividends or other distributions with respect to
the Sierra  Shares as to which the record date and payment  date  occurred on or
after the Effective Date and on or before the date of surrender.

         (c) If any  certificate  for  Sierra  Shares  is to be issued in a name
other than that in which the certificate for CCBC Shares surrendered in exchange
therefor is registered, it shall be a condition of such exchange that the person
requesting  such exchange  shall pay to the Exchange  Agent any transfer  costs,
taxes or other expenses  required by reason of the issuance of certificates  for
such Sierra Shares in a name other than the registered holder of the certificate
surrendered,  or such persons shall establish to the  satisfaction of Sierra and
the Exchange  Agent that such costs,  taxes or other  expenses have been paid or
are not applicable.

         (d) All dividends or distributions, and any cash to be paid pursuant to
Section 2.2 in lieu of  fractional  shares,  if held by the  Exchange  Agent for
payment or delivery to the holders of  unsurrendered  certificates  representing
CCBC Shares and unclaimed at the end of one year from the Effective Date,  shall
(together with any interest  earned thereon) at such time be paid or redelivered
by the Exchange Agent to Sierra, and after such time any holder of a certificate
representing  CCBC  Shares  who  has not  surrendered  such  certificate  to the
Exchange Agent shall, subject to applicable law, look as a general creditor only
to Sierra for payment or delivery of such dividends or distributions or cash, as
the case may be.

         2.4 No Further  Transfers of CCBC Shares.  At the Effective  Date,  the
stock  transfer  books of  Bancshares  shall be closed and no  transfer  of CCBC
Shares theretofore outstanding shall thereafter be made.

         2.5  Adjustments.  If,  between  the  date  of this  Agreement  and the
Effective  Date,  the  outstanding  Sierra Shares shall have been changed into a
different   number   of  shares   or  a   different   class  by  reason  of  any
reclassification, recapitalization, split up, combination, exchange of shares or
readjustment,  or a stock dividend  thereon shall be declared with a record date
within such period,  the number of Sierra  Shares to be issued and  delivered in
the Merger in exchange for each outstanding CCBC Share shall be  correspondingly
adjusted.

         2.6  Treatment of Stock Options.

         (a) On the Effective Date, the obligations under any stock option plans
of CCBC shall be assumed by Sierra.  On the Effective Date,  options to purchase
CCBC Shares  issued  pursuant to CCBC's stock  option plans shall be  converted,
without any action on the part of the holders thereof,  into options to acquire,
upon  payment of the  adjusted  exercise  price  (which shall equal the exercise
price per share for the options immediately prior to the Merger,  divided by the
Exchange  Ratio),  the number of shares of Sierra shares the option holder would
have  received  pursuant to the Merger if he or she had exercised all his or her
options immediately prior thereto.

         (b) Such stock option plan as shall be applicable to CCBC stock options
shall be  deemed to be  amended  to the  effect  that a  non-officer  Director's
service  does not  terminate as long as he or she remains a Director or advisory
Director of Sierra on and after the Effective  Date.  Sierra  covenants  that it
will,  for purposes of the CCBC stock option plan, at or  immediately  following
the Effective Date, offer each current  non-officer  Director of CCBC a position
as advisory Director of Sierra for a period of not less than 2 years.

         (c) Subject to the mutual intent of the parties that the Merger will be
accounted  for under the  pooling-of-interests  method,  Sierra  and CCBC  shall
otherwise  amend  their   respective   option  plans  and  obtain  any  required
shareholder  approvals  of such  option  plan  amendments  and shall  amend,  as
necessary,  any and all option  agreements  (including  obtaining  any  required
participant  consents)  prior to the Effective Date to make them consistent with
this Section 2.6.

         2.7  Personnel Matters.

         (a)  Employment At Effective  Date. On the Effective  Date,  except for
employees with contracts  that will be assumed by Sierra,  CCBC employees  shall
become employees at will of Sierra.  Prior to the Effective Date, CCBC may, with
the consent of Sierra,  make additional special bonus payments not to exceed six
months  salary to retain  employees  who are deemed  necessary  to complete  the
Merger and the Bank Merger. In the even that CCBC terminates  employees prior to
the  Effective  Date,  it shall  abide by all  internal  policies  and all legal
requirements  for  termination  of  employment.  From the date of this agreement
through  the  Effective  Date,  CCBC  shall  consult  with the  human  resources
representative of Sierra,  who shall be designated in writing to CCBC by Sierra,
and keep that  representative  advised as to all matters  related to employment.
From the day of the Effective Date or any time  thereafter,  former employees of
CCBC who are employed by Sierra  following the Effective  Date may be terminated
by Sierra, with or without cause, for any reason not prohibited by law.

         (b) Retirement Benefits.  Employees of Sierra formerly employed by CCBC
on the Effective Date shall be eligible for  participation  in the Sierra 401(k)
plan and employee stock option plan at the earliest  normal entry date following
the Effective  Date as allowed by applicable  law and the provisions of Sierra's
benefit plans, so long as such employees then meet the eligibility  requirements
for  participation  in the Sierra  plan.  The former  employees  of CCBC who are
employed by Sierra Bank will be credited  for years of prior  service  with CCBC
for vesting  (non-forfeitability) of accrued benefits in the Sierra plans to the
fullest extent such credit for such prior service is permitted by Sierra's plans
and by the laws,  rules and regulations of the Internal  Revenue Service and the
Employee Income Security Act of 1974, as amended.

         (c)  Other Benefit Plans.

                  (i) After the Effective  Date, any or all CCBC welfare benefit
plans shall be terminated by Sierra.  Sierra Bank employees formerly employed by
CCBC immediately prior to the Effective Date shall be eligible for participation
in any  existing  Sierra  plan,  so long as such  employee  would  otherwise  be
eligible to participate in such plan.

                  (ii)Employees of Sierra Bank formerly  employed by CCBC on the
Effective  Date  will  receive  credit  for  length  of  service  with  CCBC for
determination  of eligibility or  participation in the Sierra (A) health service
plans, or (B) long-term disability, voluntary accident and life insurance plans.

         (d)  Other Benefits.

                  (i)  Employees  of  Sierra  formerly  employed  by CCBC on the
Effective  Date will retain  vacation  benefits  accrued  with CCBC prior to the
Effective Date,  subject to Sierra's  maximum accrual and carryover  limitations
for such  benefits;  and will  also  retain  the  amount of sick  leave  benefit
eligibility  on CCBC's  records  prior to the  Effective  Date,  to be available
subject to Sierra's  policy for sick leave  benefits;  provided,  however,  such
employees  shall not be entitled to payment for carry-over  CCBC sick leave upon
termination of employment as is provided under Sierra's sick leave policy,  and,
provided further, CCBC shall have accrued the cost of such benefits on the books
of CCBC on or before the Determination  Date.  Following the Effective Date, all
employees  shall be subject to the  standard  policies  of Sierra for accrual of
such benefits.

                  (ii)Employees of Sierra Bank formerly  employed by CCBC on the
Effective  Date will be  subject  to the  severance  policies  in effect for all
Sierra employees.

         3.1  Mutual Covenants.

         (a)  Government  Approvals.  Each  party will use its  reasonable  best
efforts in good faith to take or cause to be taken as  promptly  as  practicable

provided in the Merger Agreements and this Agreement as promptly as practicable.
The  approvals  referred  to in  clauses  (i)-(iv)  of this  Section  3.1(a) are
hereinafter referred to as the "Government  Approvals." Each party shall respond

obtaining  the  Government  Approvals  promptly  and in all cases within 10 days
after receipt of such request.

         (b)   Notification  of  Breach  of   Representations,   Warranties  and
Covenants. Each party shall promptly give written notice to the other party upon
becoming  aware of the  occurrence or impending or threatened  occurrence of any
event  which  would  cause  or  constitute  a  material  breach  of  any  of the
representations,  warranties or covenants of that party contained or referred to
in the Merger  Agreements or this  Agreement and shall use its  reasonable  best
efforts to prevent the same or remedy the same promptly.

         (c)  Financial Statements.

                  (i) Each  party has  delivered  or shall  deliver to the other
party  promptly  after they become  available true and correct copies of audited
financial  statements  as of  such  date  and  covering  such  period  as may be
necessary to satisfy the minimum  requirements  of the  Securities  and Exchange
Commission ("SEC") and other governmental  authorities having approval authority
over the Merger and Bank Merger.  The  financial  statements  for such year ends
have been or shall be audited by their respective  independent  certified public
accounting  firms  which  have been  engaged  in the past and  include  or shall
include an unqualified  opinion of each such accounting firm, to the effect that
such  financial   statements   have  been  prepared  in  accordance   with  GAAP
consistently  applied  and  present  fairly,  in  all  material  respects,   the
consolidated  financial  position,  results of operations  and cash flows of the
respective parties at the dates indicated and for the periods then ending.

                  (ii) Each  party  shall  provide to the other  party  promptly

interim  quarterly  financial  statements)  since  December 31, 1994,  all proxy
statements  and other  written  material  furnished  to its  shareholders  since
December 31, 1994,  and all other  material  reports,  including  year-end  call

the  Effective  Date.  As of its date,  each of the  documents  described in the
preceding  sentence  complied or shall comply in all material  respects with all
legal and regulatory requirements applicable thereto.

written  statement for general  circulation  relating to this  Agreement  unless
previously  provided to the other party for review and approval  (which approval
will not be unreasonably withheld or delayed) and shall cooperate with the other
party in the development and  distribution of all news releases and other public
information  disclosures  with  respect to the Bank  Merger,  the  Merger,  this
Agreement or the Agreement and Plan of Merger or Bank Merger Agreement; provided
that  either  party  may,  without  the  consent  of the other  party,  make any
disclosure  with regard to this  Agreement  that it  determines,  upon advice of
counsel, is required under any applicable law or regulation.

         (e) Access to Properties, Books and Records; Confidentiality.  Prior to
the Effective  Date, each party shall (except as may be prohibited by applicable
law)  give  the  other   party  and  its   officers,   employees,   agents   and
representatives  full access,  during normal  business hours and upon reasonable
notice,  to all of its  properties,  books,  contracts,  records and  facilities
including, but not limited to, the corporate, financial and operational records,
papers,  reports,  instructions,   procedures,  tax  returns  and  filings,  tax
settlement letters,  material contracts or commitments,  regulatory examinations
and  correspondences.  Each party shall also use its reasonable  best efforts to
cause its independent  accounting firm to make available to the other party, its
accountants,  counsel and other agents,  to the extent  reasonably  requested in
connection with such review, such firm's work papers and documentation  relating
to its work papers and its audits of the books and  records of each party.  Each
party shall make available to the other  originals or copies,  at the responding
party's  election,  of such  documents  and records as the other may  reasonably
request.  The availability or actual delivery of such  information  about either

party contained in this Agreement,  the Bank Merger  Agreement and the Agreement

request. Each party shall use its reasonable best efforts to cause its officers,
directors,  employees, auditors and attorneys to cooperate with the other in its
reasonable  requests  for  information  except  that  no  information  which  is
reasonably  determined to be the subject of the attorney client  privilege shall
be required to be  disclosed.  Each party shall treat as  confidential  all such
information  in the  same  manner  as each  party  treats  similar  confidential
information of its own, and if this  Agreement is  terminated,  each party shall
continue  to treat  all  such  information  as  confidential  and to  cause  its
employees  to keep all such  information  confidential  and  shall  return  such
documents  therefore  delivered  by the  other  party as the other  party  shall
request, and shall use such information,  or cause it to be used, solely for the
purposes of evaluating  and  completing the  transactions  contemplated  hereby;
provided  that each  party  may  disclose  any such  information  to the  extent
required  by federal  or state  securities  laws or  otherwise  required  by any
governmental   agency  or  authority,   or  by  generally  accepted   accounting
principles. The foregoing confidentiality obligations shall not apply in respect
of any information publicly available or to any information  previously known to
the party in question, the use of which is not otherwise restricted.

any further  action is  necessary or desirable to carry out the purposes of this
Agreement or to vest the Surviving  Corporation and the Surviving Bank with full
title to all properties, assets, rights, approvals, immunities and franchises of
any of the parties to the Merger and the Bank  Merger,  the proper  officers and
directors of each party to this Agreement  shall take all such necessary  action
as may be reasonably  requested by, and at the sole expense of, Sierra.  Pending
the Effective Date, Sierra and CCBC shall consult with one another and cooperate

commitments  to be  entered  into by CCBC;  coordination  regarding  third-party
service  agreements  with a view to  providing  common  products and services as
expeditiously as practicable  following the Effective Date; making  arrangements
for  employee  training  prior to the  Effective  Date;  and  taking  action  to
facilitate an orderly conversion of data processing operations to occur promptly

delay or impede the Merger.

         (g) Advice of Changes.  Sierra and CCBC shall promptly advise the other
party of any change or event having, or that would be reasonably likely to have,
a  material  adverse  effect  on it or  which  it  believes  would  or  would be
reasonably  likely  to cause  or  constitute  a  material  breach  of any of its
representations, warranties or covenants contained herein.

         (h) Legal Conditions to Merger. Each of Sierra and CCBC shall use their
reasonable  best  efforts  (a) to  take,  or  cause  to be  taken,  all  actions
necessary,  proper, or advisable to comply promptly with all legal  requirements
which may be imposed on such party with  respect to the Merger  and,  subject to
the respective  conditions  set forth in Sections 7 and 8 hereof,  to consummate
the  transactions  contemplated  by this  Agreement  and (b) to  obtain  (and to
cooperate with the other party to obtain) any consent,  authorization,  order or
approval of, or any  exemption by, any  governmental  entity and any other third
party which is required to be obtained by CCBC or Sierra in connection  with the

with GAAP and RAP.  CCBC may either  accept and  implement  Sierra's  grading or
other  assessments   (including   accounting  treatment  and  loss  recognition)
concerning loans or OREO, or, if it does not agree with Sierra's  conclusions as
set forth in the report, refer the matter for resolution by the independent loan
and appraisal experts agreed to in writing by the parties (the "Independent Loan
Reviewer"  or  "Independent  Appraiser")  who shall  immediately  review  and/or
appraise said loan(s) or OREO utilizing CCBC's regular loan/OREO review criteria
consistent  with GAAP and RAP. The parties  agree that if the  Independent  Loan
Reviewer believes it necessary to retain an Independent Appraiser (or if such an
Appraiser is required by the  penultimate  sentence  below),  the  selection and
supervision  thereof of said Appraiser  shall be at the discretion and under the
control of the Independent Loan Reviewer.  CCBC agrees to recognize on its books
and records all loan  losses and record all OREO at their net  realizable  value
(and  record  related  OREO  expenses)  based  on  the  review/appraisal  by the
Independent   Loan  Reviewer  or   Independent   Appraiser  no  later  than  the
Determination  Date.  Sierra and CCBC agree to accept the  determinations of the
Independent Loan Reviewer and Independent  Appraiser.  With respect to any OREO,
based on all known  information  available from time to time, if it appears that
the then current  independent  appraisals may not be accurate or upon request of
and at the expense of Sierra,  CCBC shall immediately obtain updated independent
appraisals  by an  Independent  Appraiser  (utilizing  CCBC's  regular  criteria
consistent  with  GAAP and RAP) and  provide  copies of all such  appraisals  to
Sierra.  Any new or additional  writedowns  or OREO  expenses  shall be recorded
immediately upon receiving any updated independent  appraisal.  The costs of the
neutral loan reviewer shall be shared equally by the parties.

execution of this Agreement and as a condition  thereto,  Bancshares  shall have
executed  and  delivered  a stock  option  agreement  (the  "CCBC  Stock  Option
Agreement")  which  grants to Sierra  an  option to  acquire  up to 19.9% of the
issued  and  outstanding  CCBC  Shares  including  unconverted   debentures  and
unexercised  options to acquire  CCBC  Shares  (including  the CCBC Shares to be
granted  pursuant to the CCBC Stock  Option  Agreement  upon the  occurrence  of
certain circumstances, substantially in the form of Exhibit C hereto.

         (k)  Pre-Closing  Adjustments.  On or before the Effective  Date,  CCBC
shall,  in a  manner  mutually  satisfactory  to  the  parties,  establish  such
additional accruals and reserves consistent with GAAP and RAP as may be directed
by  Sierra;  provided,  however,  that CCBC shall not be  required  to take such
action (a) more than five days prior to the  Effective  Date,  (b) unless Sierra
agrees in writing  that all  conditions  to closing  set forth in Section 7 have
been  satisfied  or waived,  and (c) unless  CCBC shall have  received a written
waiver by Sierra of its rights to terminate  this  Agreement,  and no accrual or
reserve  made by CCBC  pursuant  to this  Section  3.2(k) or any  litigation  or
regulatory  proceeding  arising  out of  any  such  accrual  or  reserve,  shall
constitute  or be deemed to be a breach,  violation of or failure to satisfy any
representation,  warranty,  covenant,  condition  or  other  provisions  of this
Agreement or otherwise be  considered  in  determining  whether any such breach,
violation or failure to satisfy shall have occurred.

statement/prospectus  which CCBC shall assist with by providing such information
and documents as may be required in an expeditious  and timely  manner.  Bancorp
shall hold its  shareholder  meeting as soon as possible but no later than March
31, 1998 unless  prevented  from doing so by the  regulatory  authorities  or by
delays in obtaining or conditions imposed by the Government  Approvals.  Subject

                      (H) file in a timely manner (taking into account any
extensions duly obtained) all reports,  tax returns and other documents required
to be filed with federal, state, local and other authorities;

                      (I) not sell, lease, pledge, assign, encumber or otherwise
dispose of any of its assets except for adequate value, without recourse and
consistent with its customary practice; and

                      (J) not  make,  renegotiate,  renew,  increase,  extend or
purchase  any loans,  advances or loan  commitments,  in each case to any of its
officers,  directors or any  affiliated or related  persons of such directors or
officers  except in the Ordinary Course  consistent  with its  established  loan
procedures and in compliance with FRB Regulation O.

                  (ii)It is understood and agreed by the parties hereto that any
consent  sought of CCBC or required by Sierra  pursuant to any provision of this
Agreement  shall be deemed to be given following five (5) business days advanced
notice by Sierra to CCBC,  which notice shall include such  information  as CCBC
shall  reasonably  request or unless the comments of CCBC have been addressed by
Sierra.

         (c)  Dividends.  At or  after  the date  hereof  and at or prior to the
Effective Date, except for stock dividends for which adjustments are provided in
Section 2.5 or with the prior written  consent of CCBC or as otherwise  provided
in this Agreement,  Sierra shall not declare, set aside or pay any cash dividend
or other  distribution  in  respect  of its  common  stock  other  than,  in the
discretion  of the board of directors of Sierra,  regular cash  dividends not to
exceed $0.50 per share on an annual basis.

         (d)  Indemnification; Insurance.

              (i) In the event of any threatened or actual claim,  action, suit,
proceeding  or  investigation,   whether  civil,   criminal  or  administrative,
including,  without  limitation,  any such claim,  action,  suit,  proceeding or
investigation  in which any person who is now,  or has been at any time prior to
the date of this  Agreement,  or who  becomes  prior to the  Effective  Time,  a
director or officer of CCBC ("Indemnified  Parties") is, or is threatened to be,
made a party  based in whole or in part on, or  arising  in whole or in part out
of, or  pertaining  to (i) the fact that he is or was a  director  or officer of
CCBC  or any  predecessor  or (ii)  this  Agreement  or any of the  transactions
contemplated hereby, whether in any case asserted or arising before or after the
Effective Date, the parties hereto agree to cooperate and use their best efforts
to defend  against and respond  thereto.  It is understood and agreed that after
the Effective  Date,  Sierra shall  indemnify and hold  harmless,  as and to the
fullest extent permitted by law, each such Indemnified Party against any losses,
claims, damages,  liabilities,  costs, expenses (including reasonable attorney's
fees and  expenses  in advance  of the final  disposition  of any  claim,  suit,
proceeding or  investigation  to each  Indemnified  Party to the fullest  extent
permitted by law upon receipt of any  undertaking  required by applicable  law),
judgments,  fines and amounts paid in  settlement  in  connection  with any such
threatened or actual claim, action, suit, proceeding or investigation and in the
event of any such  threatened  or actual claim,  action,  suit,  proceeding,  or
investigation  (whether asserted or arising before or after the Effective Date),
the Indemnified Parties may retain counsel reasonably satisfactory to them after
consultation  with  Sierra;  provided,  however,  that (1) Sierra shall have the
right to assume the defense thereof and upon such assumption Sierra shall not be
liable to any  Indemnified  Party for any legal expenses of other counsel or any
other expenses subsequently incurred by any Indemnified Party in connection with
the defense thereof,  except that if Sierra elects not to assume such defense or
counsel for the Indemnified  Parties reasonably advises the Indemnified  Parties
that there are issues which raise  conflicts of interest  between Sierra and the
Indemnified  Parties,  the  Indemnified  Parties may retain  counsel  reasonably
satisfactory to them after  consultation  with Sierra,  and Sierra shall pay the
reasonable  fees and expenses of such counsel for the Indemnified  Parties,  (2)
Sierra shall be obligated pursuant to this paragraph to pay for only one firm of
counsel for all  Indemnified  Parties,  unless an  Indemnified  Party shall have
reasonably  concluded;  based  on the  advice  of  counsel,  that in order to be
adequately  represented,  separate  counsel is  necessary  for such  Indemnified
Party,  in which  case,  Sierra  shall  be  obligated  to pay for such  separate
counsel,  (3) Sierra shall not be liable for any settlement effected without its
prior written  consent (which consent shall not be unreasonably  withheld),  and
(4) Sierra shall have no obligation  hereunder to any Indemnified Party when and
if a court  of  competent  jurisdiction  shall  ultimately  determine,  and such
determination shall have become final and nonappealable, that indemnification of
such  Indemnified  Party in the  manner  contemplated  hereby is  prohibited  by
applicable law. Any  Indemnified  Party wishing to claim  Indemnification  under
this Section 3.3(d), upon learning of any such claim, action,  suit,  proceeding
or investigation,  shall notify Sierra thereof,  provided that the failure to so
notify shall not affect the  obligations  of Sierra  under this  Section  3.3(d)
except to the  extent  such  failure  to notify  materially  prejudices  Sierra.
Sierra's obligations under this Section 3.3(d) continue in full force and effect
for a period of four (4) years from the Effective Date; provided,  however, that
all rights to indemnification in respect of any claim ("Claim") asserted or made
within such period shall continue until the final  disposition of such Claim and
provided further that Sierra shall have the right of setoff against any payments
required to be made by Sierra to an  Indemnified  Party pursuant to this Section
3.3(d) to the  extent  that such  Indemnified  Party  shall  have  received  the
indemnification  to which such  Indemnified  Party is  entitled  from an insurer
under a directors' and officers'  liability  insurance policy maintained by CCBC
or Sierra.

              (ii)Sierra,  from and after the Effective  Date,  will directly or
indirectly  cause the persons who served as  directors or officers of CCBC on or
before the  Effective  Date to be covered by Sierra's  existing  directors'  and
officers'  liability  insurance  policy  (provided  that  Sierra may  substitute
therefor policies of at least the same coverage and amounts containing terms and
conditions which are not less  advantageous  than such policy) or so-called tail
coverage obtained in connection with CCBC's  directors' and officers'  liability
insurance  policies in effect as of the  Effective  Date;  provided  that Sierra
shall not be obligated to make annual premium payments for such insurance to the
extent such  premiums  exceed 150% of the premiums paid as of the date hereof by
CCBC for such  insurance.  Subject to the  preceding  sentence,  such  insurance
coverage, shall commence on the Effective Date and will be provided for a period
of no less than three  years  after the  Effective  Date.  From the date  hereof
through the Effective Date and subject to the foregoing, CCBC shall use its best
efforts to arrange for tail  coverage  related to its then  current  policies of
directors'  and officers'  liability  insurance and following the Effective Date
Sierra  shall  exercise  those  rights which it may have to in order to commence
such coverage.

              (iii) In the event Sierra or any of its  successors or assigns (A)
consolidates  with  or  merges  into  any  other  person  and  shall  not be the
continuing or surviving  corporation or entity of such  consolidation or merger,
or (B)  transfers  or conveys all or  substantially  all of its  properties  and
assets to any  person,  then,  and in each such case,  to the extent  necessary,
proper  provision  shall be made so that the  successors  and  assigns of Sierra
assume the obligations set forth in this section. The provisions of this Section
3.3(d) are intended to be for the benefit of, and shall be enforceable  by, each
Indemnified Party and his or her heirs and representatives.

Section 4.  REPRESENTATIONS AND WARRANTIES OF CCBC.

         CCBC  represents  and warrants to Sierra  that,  except as set forth in
writing corresponding in number with the applicable section:

         4.1 Corporate Status and Power to Enter Into Agreements. (i) Bancshares
is a corporation duly  incorporated,  validly existing under Delaware law and in
good  standing  under the laws of the states of Delaware  and  California,  (ii)
subject to the  Government  Approvals and to the approval of this  Agreement and
the transactions contemplated hereby by the shareholders of Bancshares, CCBC has
all  necessary  corporate  power to enter into this  Agreement,  the Bank Merger
Agreement and the Agreement and Plan of Merger and to carry out all of the terms
and  provisions  hereof  and  thereof to be  carried  out by it,  (iii) CPB is a
California  banking  corporation  duly licensed by the Commissioner to engage in
the business of commercial  banking in  California  at its  principal  office in
Vacaville,  California and at its branch offices and (iv) neither Bancshares nor
CPB is subject to any order of the FRB, the FDIC, the  Commissioner or any other
regulatory  authority having jurisdiction over its business or any of its assets
or properties. Neither the scope of the business of CCBC nor the location of its
properties  requires it to be licensed to do business in any jurisdiction  other
than the State of  California.  CPB's  deposits  are  insured by the FDIC to the
maximum extent permitted by applicable law and regulation.

         4.2 Articles,  Bylaws, Books and Records. The copies of the Certificate
of Incorporation  of Bancshares,  Articles of Incorporation of CPB and Bylaws of
CCBC heretofore  delivered to Sierra are complete and accurate copies thereof as
in effect on the date hereof.  The minute books of CCBC made available to Sierra
contain a  complete  and  accurate  record of all  meetings  of CCBC's  Board of
Directors (and  committees  thereof) and  shareholders.  The corporate books and
records  (including  financial  statements)  of CCBC fairly reflect the material
transactions  to which CCBC is a party or by which its properties are subject or
bound, and such books and records have been properly kept and maintained.

         4.3 Compliance  With Laws,  Regulations  and Decrees.  CCBC (i) has the
corporate  power to own or lease its  properties  and to conduct its business as
currently conducted,  (ii) has complied with, and is not in default of any laws,
regulations,  ordinances,  orders or decrees  applicable  to the  conduct of its
business and the ownership of its  properties,  including but not limited to all
federal  and state laws  (including  but not limited to the Bank  Secrecy  Act),
rules and regulations relating to the offer, sale or issuance of securities, and
the  operation  of a  commercial  bank other than  where such  noncompliance  or
default is not likely to result in a material  limitation  on the conduct of its
business or is not likely to otherwise  have a material  adverse  effect on CCBC
taken as a whole,  (iii) has not failed to file with the proper federal,  state,
local or other  authorities any material report or other document required to be
filed,  and  (iv)  has  all  approvals,   authorizations,   consents,  licenses,
clearances and orders of, and has currently  effective all  registrations  with,
all governmental and regulatory  authorities which are necessary to the business
and operations of CCBC as now being conducted.

         4.4  Capitalization.  As of October 31, 1997,  the  authorized  capital
stock of Bancshares consists of 4,000,000 CCBC Shares, $0.10 par value, of which
1,096,331 are duly authorized,  validly issued, fully paid and nonassessable and
currently  outstanding,  1,000,000  shares of  preferred  stock none of which is
outstanding.  Said  stock has been  issued  in  compliance  with all  applicable
securities laws. As of October 31, 1997,  there were  outstanding  $2,503,000 of
Bancshares debentures  ("Bancshares  Debentures")  convertible into 196,314 CCBC
Shares. There are currently outstanding options to purchase 129,036 CCBC Shares,
at a weighted average exercise price of $10.82 per share, issued pursuant to its
1990 and 1993 Stock Option Plan.  Said options were issued and, upon issuance in
accordance  with the  terms of the  outstanding  options  said  shares  shall be
issued, in compliance with all applicable securities laws. Otherwise,  there are
no outstanding  (i) options,  agreements,  calls or commitments of any character
which would  obligate  Bancshares to issue,  sell,  pledge,  assign or otherwise
encumber or dispose of, or to purchase,  redeem or otherwise acquire, any Sierra
common stock or any other equity  security of  Bancshares,  or (ii)  warrants or
options relating to, rights to acquire, or debt or equity securities convertible
into,  shares  of  Bancshares  common  stock or any  other  equity  security  of
Bancshares. The outstanding common stock of Bancshares has been duly and validly
registered  with  the SEC  pursuant  to the 1934  Act,  to the  extent  required
thereunder

         4.5 Equity Interest in Any Entity. Except as collateral for outstanding
loans held in its loan  portfolio  and its ownership of CPB and its wholly owned
subsidiary,  CCBC does not own,  directly or indirectly,  any equity interest in
any bank, corporation or other entity.

         4.6 Financial Statements, Regulatory Reports. No financial statement or
other document to be provided to Sierra by CCBC under this Agreement,  as of the
date of such document,  contained,  or as to documents to be delivered after the
date hereof,  will contain,  any untrue statement of a material fact, or, at the
date thereof,  omitted or will omit to state a material fact  necessary in order
to make the statements  contained therein,  in light of the circumstances  under
which such statements were or will be made, not misleading;  provided,  however,
that information as of a later date shall be deemed to modify  information as of
any earlier date. CCBC has filed all material  documents and reports required to
be filed by it with the SEC, the FRB, the FDIC, the  Commissioner  and any other
governmental  authority  having  jurisdiction  over its  business  or any of its
assets or properties. All such reports conform in all material respects with the
requirements   promulgated  by  such  regulatory  agencies.  All  compliance  or
corrective  action  relating to CCBC required by  governmental  authorities  and
regulatory  agencies having jurisdiction over either Bancshares or CPB have been
taken, including compliance with any of the FRB, the FDIC or the Commissioner in
their most recent Reports of Examination.  CCBC's composite CAMELS rating in its
most  recent  Reports  of  Examination  is a "1" or a "2" and its CRA  rating is
"outstanding"  or  "satisfactory'  and CCBC has not been  notified  formally  or
informally that such ratings may be changed by any bank regulatory agency having
authority  over  CCBC.  CCBC has not  received  any  notification,  formally  or
informally,  from  any  agency  or  department  of any  federal,  state or local
government or any  regulatory  agency or the staff thereof (i) asserting that it
is not in compliance with any of the statutes,  regulations or ordinances  which
such government or regulatory  authority enforces,  where such non-compliance or
default  is likely to result in a  material  limitation  on the  conduct  of its
business or is not likely to otherwise  have a material  adverse  effect on CCBC
taken as a whole, or (ii) threatening to revoke any license,  franchise,  permit
or governmental authorization.  CCBC has paid all assessments made or imposed by
any  governmental  agency.  CCBC has  delivered  to Sierra  copies of all annual
management letters and opinions, and has made available to Sierra for inspection
all reviews, correspondence and other documents in the files of CCBC prepared by
its  independent  accounting firm delivered to CCBC since December 31, 1996. The
financial  records of CCBC have been, and are being and shall be,  maintained in
all material  respects in accordance  with all  applicable  legal and accounting
requirements  sufficient to insure that all transactions  reflected therein are,
in all material  respects,  executed in accordance with management's  general or
specific  authorization  and  recorded in  conformity  with  generally  accepted
accounting principles at the time in effect. The data processing equipment, data
transmission  equipment,  related peripheral equipment and software used by CCBC
in the operation of its business to generate and retrieve its financial  records
are adequate for the current needs of CCBC.

         4.7  Tax Returns.

                  (i) CCBC has timely filed (taking into account any  extensions
duly  obtained)  all  federal,  state,  county,  local and  foreign  tax returns
required to be filed by it, including,  without  limitation,  estimated tax, use
tax,  excise tax, real  property and personal  property tax reports and returns,
employer's  withholding tax returns,  other  withholding tax returns and Federal
Unemployment Tax Returns, and all other reports or other information required or
requested to be filed by it, and each such return,  report or other  information
was, when filed,  complete and accurate in all material respects.  CCBC has paid
all taxes,  fees and other  governmental  charges,  including  any  interest and
penalties  thereon,  shown on such  returns as due,  except those that are being
contested in good faith,  which contested  matters have been disclosed to Sierra
and are disclosed on Schedule 4.7 hereto. CCBC has not been requested to give or
has given any currently  effective  waivers  extending  the statutory  period of
limitation  applicable  to any tax  return  required  to be  filed by it for any
period.  Other than as  disclosed  in  writing  to  Sierra,  there are no claims
pending against CCBC for any alleged deficiency in the payment of any taxes, and
no  officer  of CCBC  responsible  for  tax  matters  knows  of any  pending  or
threatened audits,  investigations or claims for unpaid taxes or relating to any
liability  in respect of any taxes.  As to such tax claims,  CCBC has accrued on
its books an amount  that is believed  to be  sufficient  to pay all such taxes,
including  interest  and  penalties  that may be due,  and has reduced  tangible
shareholders' equity by such amount. There has been no event, including a change
in ownership,  that would result in a  reappraisal  and  establishment  of a new
base-year   full  value  for  purposes  of  Article  XIII.A  of  the  California
Constitution,  of any  real  property  owned  in  whole or in part by CCBC or to
CCBC's knowledge, of any real property leased by CCBC.

                  (ii)CCBC has  delivered to Sierra copies of all its income and
franchise  tax returns  with  respect to taxes  payable to the United  States of
America and the State of California for the fiscal years ended December 31, 1995
and 1996.

                  (iii) No consent has been filed  relating to CCBC  pursuant to
Section 341(f) of the IRC.

         4.8 Material Adverse Change.  Except as heretofore disclosed in writing
by CCBC to Sierra,  since  December  31,  1996,  there has been (i) no  material
adverse change in the business, assets, licenses, permits,  franchises,  results
of  operations  or financial  condition of CCBC  (whether or not in the Ordinary
Course), (ii) no change in any of the assets, licenses, permits or franchises of
CCBC that has had or can  reasonably  be  expected  to have a  material  adverse
effect  on any of the  items  listed  in  clause  (i)  above,  (iii) no  damage,
destruction,  or other casualty loss (whether or not covered by insurance)  that
has had or can  reasonably be expected to have a material  adverse effect on any
of the items listed in clause (i) above,  (iv) no  amendment,  modification,  or
termination of any existing,  or entering into of any new, contract,  agreement,
plan,  lease,  license,  permit or franchise  that is material to the  business,
financial  condition,  assets,  liabilities or operations of CCBC, except in the
Ordinary  Course;  and (v) no  disposition  by CCBC of one or more assets  that,
individually or in the aggregate,  are material to CCBC,  except sales of assets
in the Ordinary Course.

         4.9 No  Undisclosed  Liabilities.  Except as  previously  disclosed and
except  for items for  which  reserves  have been  established  or  accrued  and
recorded in the audited balance sheets of CCBC as of December 31, 1996, CCBC has
not incurred or  discharged,  and is not legally  obligated  with respect to any
indebtedness,  liability (including, without limitation, a liability arising out
of an  indemnification,  guarantee,  hold  harmless or similar  arrangement)  or
obligation (accrued or contingent,  whether due or to become due, and whether or
not  subordinated  to the claims of its general  creditors),  which would have a
material  effect on the  capital or  earnings  of CCBC other than as a result of
operations  in the  Ordinary  Course after such date.  No agreement  pursuant to
which any loans or other  assets have been or will be sold by CCBC  entitled the
buyer of such  loans or other  assets,  unless  there is  material  breach  of a
representation  or covenant by the seller, to cause CCBC to repurchase such loan
or other asset or the buyer to pursue any other form of recourse  against  CCBC.
CCBC has not knowingly made and shall not make any representation or covenant in
any such  agreement  that  contained or shall contain any untrue  statement of a
material  fact or omitted or shall omit to state a material  fact  necessary  in
order to make the statements  contained  therein,  in light of the circumstances
under which such  representations  and/or  covenants were made or shall be made,
not misleading.  Other than regular quarterly dividends, no cash, stock or other
dividend or any other  distribution  with  respect to the stock of CCBC has been
declared,  set  aside or paid,  nor have any  shares  of the  stock of CCBC been
purchased, redeemed or otherwise acquired, directly or indirectly, by CCBC since
December 31, 1996.

         4.10  Properties and Leases.

         (a) CCBC has good and marketable title, free and clear of all liens and
encumbrances and the right of possession, subject to existing leaseholds, to all
real properties and good title, free and clear of all liens and encumbrances, to
all other property and assets,  tangible and  intangible,  reflected in the CCBC
balance  sheet as of December  31, 1996  (except  property  held as lessee under
leases  disclosed  in  writing  prior to the date  hereof  and  except  personal
property sold or otherwise  disposed of since December 31, 1996, in the Ordinary
Course),  except (i) liens for taxes or assessments  not  delinquent,  (ii) such
other liens and  encumbrances  and  imperfections  of title as do not materially
affect the value of such  property as reflected in the CCBC balance  sheet as of
December  31, 1996,  or as currently  shown on the books and records of CCBC and
which do not  interfere  with or impair its present  and  continued  use,  (iii)
exceptions  disclosed in title reports and preliminary title reports,  copies of
which have been provided to Sierra.  All tangible  properties of CCBC conform in
all material  respects with all applicable  ordinances,  regulations  and zoning
laws.  All tangible  properties of CCBC are in a good state of  maintenance  and
repair and are adequate for the current business of CCBC. No properties of CCBC,
and,  to CCBC's  knowledge,  no  properties  in which it holds a  collateral  or
contingent  interest  or  purchase  option,  are the  subject of any  pending or
threatened  investigation,  claim or proceeding  relating to the use, storage or
disposal on such property of or  contamination  of such property by any toxic or
hazardous waste material or substance.  To CCBC's knowledge,  CCBC does not own,
possess or have a collateral  or contingent  interest or purchase  option in any
properties or other assets which  contain or have located  within or thereon any
hazardous  or toxic waste  material  or  substance  unless the  location of such
hazardous or toxic waste material or other substance or its use thereon conforms
in all  material  respect  with  all  federal,  state  and  local  laws,  rules,
regulations or other  provisions  regulating the discharge of materials into the
environment.  As to any  asset  not  owned  or  leased  by  CCBC,  CCBC  has not
controlled,  directed or participated in the operation or management of any such
asset or any facilities or enterprise conducted thereon, such that it has become
an owner or operator of such asset under applicable environmental laws.

         (b) All  properties  held by CCBC  under  leases  are  held by it under
valid,  binding and enforceable leases, with such exceptions as are not material
and do not interfere  with the conduct of the business of CCBC,  and CCBC enjoys
quiet and peaceful possession of such leased property. CCBC is not in default in
any respect  under any material  lease,  agreement or  obligation  regarding its
properties to which it is a party or by which it is bound.

         (c) Except as disclosed to Sierra in writing,  all of CCBC's rights and
obligations under the leases referred to in Section (b) above do not require the
consent of any other party to the  transactions  contemplated  by this Agreement
and the Merger  Agreements.  Where  required,  CCBC shall  obtain,  prior to the
Effective Date, the consent of all parties to any such transaction.

         4.11 Material  Contracts.  Except as previously  disclosed to Sierra in
writing and excluding  loans,  lines of credit,  loan  commitments or letters of
credit to which CCBC is a party, CCBC is not a party to or bound by any contract
or other agreement made in the Ordinary Course which involves  aggregate  future
payments by or to CCBC of more than $25,000 and which is made for a fixed period
expiring more than one year from the date hereof,  and CCBC is not a party to or
bound by any agreement not made in the Ordinary  Course which is to be performed
at or after the date hereof.  Each of the contracts and agreements  disclosed to
Sierra  pursuant to this Section is a legal and binding  obligation  (subject to
applicable  bankruptcy,  insolvency and similar laws affecting creditors' rights
generally and subject, as to enforceability,  to equitable principles of general
applicability),  and no material breach or default (and no condition which, with
notice or passage of time, or both,  could become a material  breach or default)
exists with respect thereto.

         4.12 Loans.  CCBC has  disclosed to Sierra in writing prior to the date
hereof,  and will promptly  inform  Sierra of the amounts of all loans,  leases,
other extensions of credit or commitments,  or other interest-bearing  assets of
CCBC,  that have been  classified  as of the date  hereof  or  hereafter  by any
internal  bank examiner or any bank  regulatory  agency or the  Commissioner  as
"Other Loans Specially Mentioned," "Special Mention," "Substandard," "Doubtful,"
"Loss," or words of similar import in the case of loans (or that would have been
so  classified,  in the case of other  interest-bearing  assets,  had they  been
loans).  CCBC has  furnished  and will  continue  to furnish to Sierra  true and
accurate  information  concerning  the loan  portfolio of CCBC,  and no material
information with respect to the loan portfolio has been or will be withheld from
Sierra.  All  loans  and  investments  of CCBC  are  legal,  valid  and  binding
obligations  enforceable in accordance with its terms and are not subject to any
setoffs, counterclaims or disputes (subject to applicable bankruptcy, insolvency
and similar laws  affecting  creditors'  rights  generally  and  subject,  as to
enforceability,  to equitable  principles of general  applicability),  except as
disclosed to Sierra in writing or reserved  for in the balance  sheet of CCBC as
of September  30, 1997,  and were duly  authorized  under and made in compliance
with applicable  federal and state laws and regulations.  CCBC does not have any
extensions of credit,  investments,  guarantees,  indemnification  agreements or
commitments  for the same  (including  without  limitation  commitments to issue
letters of credit, to create acceptances,  or to repurchase securities,  federal
funds or other assets)  other than those  documented on the books and records of
CCBC.

         4.13  Restrictions on Investments.  Except for pledges to secure public
and trust deposits and repurchase agreements in the Ordinary Course, none of the
investments  reflected in the CCBC  unaudited  balance sheet as of September 30,
1997,  and none of the  investments  made by CCBC since  September  30, 1997, is
subject to any restriction,  whether contractual or statutory,  which materially
impairs the  ability of CCBC to freely  dispose of such  investment  at any time
except  as  restricted  by any  applicable  banking,  securities  or  government
regulations.

         4.14  Employment Contracts and Benefits.

         (a) CCBC shall  deliver to Sierra an accurate  list  setting  forth all
bonus,  incentive  compensation,   profit-sharing,  pension,  retirement,  stock
purchase,  stock  option,  deferred  compensation,  severance,  hospitalization,
medical, dental, vision, group insurance,  death benefits,  disability and other
fringe benefit plans,  trust  agreements,  arrangements  and commitments of CCBC
(including  but  not  limited  to  such  plans,  agreements,   arrangements  and
commitments  applicable to former employees or retired  employees,  or for which
such  persons are  eligible),  if any,  together  with copies of all such plans,
agreements,  arrangements  and  commitments  that  are  documented,  any and all
contracts of employment and has made available to Sierra any Board of Directors'
minutes (or committee minutes) authorizing, approving or guaranteeing such plans
and contracts.

         (b) All contributions,  premiums or other payments due from CCBC to (or
under) any plan  listed in  subsection  (a) have been  fully paid or  adequately
provided for through periodic  accruals or otherwise on its unaudited  financial
statements  for the  period  ended  September  30,  1997.  Except as  previously
discussed,  all accruals thereon  (including,  where  appropriate,  proportional
accruals  for  partial  periods)  have been made in  accordance  with  generally
accepted accounting principles consistently applied on a reasonable basis.

         (c) To CCBC's actual knowledge without  conducting due diligence,  each
plan listed in subsection (a) complies with all material requirements of (i) the
Age  Discrimination  in Employment Act of 1967, as amended,  and the regulations
thereunder  and (ii) Title VII of the Civil Rights Act of 1964, as amended,  and
the regulations thereunder.

         (d) To CCBC's actual knowledge without  conducting due diligence,  each
plan listed in  subsection  (a) complied with all material  requirements  of the
health care continuation  coverage provisions of the Consolidated Omnibus Budget
Reconciliation Act of 1985 and the regulations thereunder.

         (f) CCBC has  heretofore  disclosed  in  writing to Sierra the names of
each director, officer and employee of CCBC.

         4.15 Compliance with ERISA.  CCBC has not, since its inception,  either
maintained or  contributed  to an employee  pension  benefit plan, as defined in
Section  3(2)  of  ERISA,   including   multi-employer  plans,  other  than  the
Continental  Pacific  Bank  Profit  Sharing  Plan (the  "CCBC  Plan")  which was
originally  adopted by CCBC on November  1, 1988 and amended and  restated as of
January 1, 1996,  and a true and  accurate  copy of which has been  provided  to
Sierra.  With respect to the CCBC Plan and its related trust (the "CCBC Trust"),
as of  the  Effective  Date  to  CCBC's  actual  knowledge  based  upon  written
communication from the California Bankers  Association ("CBA") and any agents of
the CBA responsible  for oversight of the CCBC Plan and the CCBC Trust,  (i) the
CCBC Plan will in all material respects be (and currently is) in compliance with
all the applicable requirements of Section 401(a) of the IRC, and the CCBC Trust
will be exempt from income tax under  Section  501(a) of the IRC;  (ii) the CCBC
Plan is a  adaptation  of a prototype  document  which has  received a favorable
opinion  letter from the IRS, the qualified  status of the CCBC Plan as adopted,
under Section 401(a) of the IRC will be determined  upon the filing with the IRS
of a request for a favorable determination to be made before September 26, 1991,
or such  other  date  prescribed  by the  IRS,  and the IRS has not  raised  any
question on audit or otherwise with respect to the qualified  status of the CCBC
Plan or the CCBC Trust prior to the  Effective  Date;  (iii) CCBC shall not have
amended the CCBC Plan or administered  the CCBC Plan in such a manner that would
preclude the issuance of a favorable  Determination  Letter to the CCBC Plan and
Trust; (iv) no contributions  have exceeded the limitations set forth in Section
415 of the IRC; (v) all required and necessary filings with the IRS,  Department
of Labor and any other  governmental  agencies with respect to the CCBC Plan and
CCBC Trust for all periods  ending at or prior to the  Effective  Date will have
been  made on a  timely  basis by CCBC and the  plan  administrator;  (vi)  with
respect to  participation  of CCBC employees in the CCBC Plan,  there shall have
been no material violation of Parts 1 and 4 of Subtitle B of Title I of ERISA or
of Section  4975 of the IRC;  and (vii) with  respect to  participation  of CCBC
employees in the CCBC Plan, there shall have been no action,  claim or demand of
any kind known to CCBC  brought  or  threatened  by any  potential  claimant  or
representative of such claimant under the CCBC Plan or CCBC Trust where CCBC may
be either (A) liable directly on such action,  claim or demand, or (B) obligated
to indemnify any person, group of persons or entity with respect to such action,
claim or demand,  unless  such  action,  claim or demand is covered by  adequate
reserves reflected in CCBC's September 30, 1997 unaudited  financial  statements
or an  insurer of CCBC has  agreed to defend  against  and pay the amount of any
resulting liability without reservation.

         4.16  Collective  Bargaining  and  Employment  Agreements.   Except  as
provided in this Agreement or as previously disclosed to Sierra in writing, CCBC
does  not  have  any  union  or  collective  bargaining  or  written  employment
agreements,  contracts or other  agreements with any labor  organization or with
any member of  management,  or any  management  or  consultation  agreement  not
terminable at will by CCBC and no such contract or agreement has been  requested
by, or is under  discussion by  management  with,  any group of  employees,  any
member of management or any other  person.  There are no material  controversies
pending  between  CCBC  and any  current  or  former  employees,  and to  CCBC's
knowledge,  there are no efforts presently being made by any labor union seeking
to organize any of such employees.

         4.17  Compensation  of Officers  and  Employees.  Except as  previously
disclosed to Sierra in writing,  (i) no officer or employee of CCBC is receiving
aggregate  direct  remuneration at a rate exceeding  $60,000 per annum, and (ii)
the  consummation of the transactions  contemplated by this Agreement,  the Bank
Merger  Agreement and the Agreement and Plan of Merger will not (either alone or
upon the  occurrence of any  additional or further acts or events) result in any
payment (whether of severance pay or otherwise) becoming due from CCBC or Sierra
to any employee of CCBC.

         4.18 Legal Actions and Proceedings.  Except as previously  disclosed to
Sierra in writing, CCBC is not a party to, or so far as either of them is aware,
threatened with, and to CCBC's knowledge,  there is no reasonable basis for, any
legal  action  or other  proceeding  or  investigation  before  any  court,  any
arbitrator of any kind or any government  agency, and CCBC is not subject to any
potential  adverse  claim,  the  outcome of which  could  involve the payment or
receipt  by CCBC of any amount in excess of  $50,000,  unless an insurer of CCBC
has  agreed to defend  against  and pay the  amount of any  resulting  liability
without reservation, or, if any such legal action, proceeding,  investigation or
claim will not  involve the  payment by CCBC of a monetary  amount,  which could
materially adversely affect CCBC or its business or property or the transactions
contemplated  hereby.  CCBC has no knowledge of any pending or threatened claims
or charges under the Community  Reinvestment  Act,  before the Equal  Employment
Opportunity  Commission,  the  California  Department of Fair Housing & Economic
Development,  the California  Unemployment Appeals Board, or any human relations
commission. There is no labor dispute, strike, slow-down or stoppage pending or,
to CCBC's knowledge, threatened against CCBC.

         4.19  Execution and Delivery of the Agreements.

         (a) The  execution  and  delivery  of this  Agreement  have  been  duly
authorized  by the  Boards of  Directors  of CCBC  and,  when the  Merger,  this
Agreement,  the Bank Merger  Agreement and the Agreement and Plan of Merger have
been or will  be duly  approved  by the  affirmative  vote of the  holders  of a
majority of the  outstanding  shares of Bancshares  common stock at a meeting of
shareholders  duly called and held,  the Merger,  this  Agreement and the Merger
Agreements will be duly and validly authorized by all necessary corporate action
on the part of CCBC.

         (b) This  Agreement  has been duly  executed and  delivered by CCBC and
(assuming due execution and delivery by Sierra) constitutes, and the Bank Merger
Agreement and the  Agreement  and Plan of Merger upon  execution and delivery by
CCBC (and assuming due execution and delivery by Sierra) will constitute,  legal
and  binding  obligations  of  CCBC in  accordance  with  its  terms  except  as
enforcement may be limited by general  principles of equity whether applied in a
court of law or a court of equity and by bankruptcy, insolvency and similar laws
affecting creditor's rights and remedies generally.

         (c) The  execution  and  delivery by CCBC of this  Agreement,  the Bank
Merger  Agreement and the Agreement and Plan of Merger and the  consummation  of
the  transactions  herein  and  therein  contemplated  (i)  do not  violate  any
provision of the  Certificate of  Incorporation  of Bancshares,  the Articles of
Incorporation of CPB or Bylaws of CCBC or, to CCBC's knowledge, any provision of
federal  or state  law or any  governmental  rule or  regulation  (assuming  (A)
receipt of the  Government  Approvals,  (B) receipt of the requisite  Bancshares
shareholder  approval,  (C) due  registration  of the  Sierra  Shares  under the
Securities  Act of 1933,  as amended  ("1933 Act"),  (D) receipt of  appropriate
permits or approvals under state securities or "blue sky" laws, and (E) accuracy
of the  representations  of  Sierra  set  forth  herein),  and  (ii)  to  CCBC's
knowledge,  do not  require  any  consent of any person  except as  contemplated
herein,  conflict with or result in a breach of, or accelerate  the  performance
required by any of the terms of, any material debt instrument,  lease,  license,
covenant,  agreement or understanding to which CCBC is a party or by which it is
bound or any order, ruling, decree,  judgment,  arbitration award or stipulation
to which CCBC is subject,  or  constitute a default  thereunder or result in the
creation of any lien, claim, security interest, encumbrance, charge, restriction
or right of any third party of any kind whatsoever upon any of the properties or
assets of CCBC.

         4.20  Retention  of Broker or  Consultant.  Other  than Van  Kasper and
Company, no broker, agent, finder,  consultant or other party (other than legal,
compliance,  loan auditors and accounting advisors) has been retained by CCBC or
is entitled to be paid based upon any agreements, arrangements or understandings
made by CCBC in connection  with any of the  transactions  contemplated  by this
Agreement  or the  Merger  Agreements.  Van Kasper and  Company  will  render an
opinion  regarding  the  fairness of the Merger from a financial  point of view.
CCBC shall provide Sierra with a true and accurate copy of its agreement(s) with
such firm.  Except as  previously  disclosed,  all costs related to such opinion
shall be paid or accrued prior to the Effective Date.

         4.21 Insurance.  CCBC is and continuously since its inception has been,
insured with reputable  insurers  against all risks normally  insured against by
California  commercial  banks,  and  all of the  insurance  policies  and  bonds
maintained  by CCBC  are in  full  force  and  effect,  CCBC  is not in  default
thereunder and all material claims  thereunder have been filed in due and timely
fashion. In the best judgment of the management of CCBC, such insurance coverage
is adequate for CCBC.  Except as  disclosed to Sierra in writing,  there has not
been any damage to, destruction of, or loss of any assets of CCBC not covered by
insurance  that could  materially and adversely  affect the business,  financial
condition, properties, assets or results of operations of CCBC.

         4.22 Loan Loss  Reserves.  To the knowledge of CCBC's  management,  the
allowance  for loan  losses as of the  Effective  Date will be  adequate  in all
material  respects under the  requirements  of all applicable  state and federal
laws and  regulations to provide for possible loan losses on outstanding  loans,
net of recoveries.

         4.23 Transactions With Affiliates.  Except as may arise in the Ordinary
Course,  CCBC has not extended  credit,  committed  itself to extend credit,  or
transferred any asset to or assumed or guaranteed any liability of the employees
or directors of CCBC,  or any spouse or child of any of them, or to any of their
"affiliates"  or  "associates"  as such terms are  defined in Rule 405 under the
1933 Act. CCBC has not entered into any other transactions with the employees or
directors  of CCBC or any  spouse  or  child  of any of  them,  or any of  their
affiliates  or  associates,  except as disclosed in writing to Sierra.  Any such
transactions have been on terms no less favorable to CCBC than those which would
prevail in an arms-length transaction with an independent third party.

         4.24  Information in Sierra  Registration  Statement.  The  information
pertaining  to CCBC  which has been or will be  furnished  to  Sierra  for or on
behalf of CCBC for inclusion in the Sierra Registration  Statement and the Joint
Proxy  Materials,  or in the  applications  to be filed to obtain the Government
Approvals  ("Applications"),  does not and will not contain any untrue statement
of any material fact or omit or will 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 are made, not misleading; provided, however, that
information  of a later  date  shall be deemed to  modify  information  as of an
earlier  date.  All  financial  statements  of CCBC  included in the Joint Proxy
Materials will present fairly the financial  condition and results of operations
of CCBC  at the  dates  and  for the  periods  covered  by  such  statements  in
accordance with generally accepted accounting  principles  consistently  applied
throughout the periods  covered by such  statements.  CCBC shall promptly advise
Sierra in writing if prior to the Effective Date CCBC shall obtain  knowledge of
any facts  that  would  make it  necessary  to amend or  supplement  the  Sierra
Registration Statement, the Joint Proxy Materials or the Applications,  in order
to make the statements therein not misleading or to comply with applicable law.

         4.25 Pooling of  Interests.  CCBC knows of no reason  relating to it or
any of its  subsidiaries  which would  reasonably  cause it to believe  that the
Merger  will not  qualify as a pooling of  interests  for  financial  accounting
purposes.

         4.26 Derivatives Contracts; Structured Notes; Etc. Except as previously
disclosed,  CCBC is not a party to nor has it agreed to enter  into an  exchange
traded or  over-the-counter  equity,  interest rate,  foreign  exchange or other
swap, forward,  future,  option, cap, floor or collar or any other contract that
is not included on the balance  sheet and is a derivatives  contract  (including
various combinations  thereof) (each, a "Derivatives  Contract") nor does it own
securities that (1) are referred to generically as "structured notes," high risk
mortgage  derivatives,"  "capped  floating rate notes" or "capped  floating rate
mortgage  derivatives" or (2) are likely to have changes in value as a result of
interest or exchange rate changes that  significantly  exceed normal  changes in
value  attributable  to  interest  or exchange  rate  changes,  except for those
Derivatives Contracts and other instruments legally purchased or entered into in
the  ordinary  course  of  business,  consistent  with  safe and  sound  banking
practices and  regulatory  guidelines,  and  previously  disclosed in writing to
Sierra. All of such Derivatives  Contracts or other instruments are legal, valid
and binding  obligations  of CCBC  enforceable  in  accordance  with their terms
(except as  enforcement  may be limited by general  principles of equity whether
applied in a court of law or a court of equity and by bankruptcy, insolvency and
similar laws affecting  creditors'  rights and remedies  generally),  and are in
full force and effect.  CCBC has duly performed in all material  respects all of
their  material  obligations  thereunder to the extent that such  obligations to
perform  have  accrued;  and,  to  CCBC's  knowledge,  there  are  no  breaches,
violations  or  defaults  or  allegations  or  assertions  of such by any  party
thereunder  which would have or would  reasonably be expected to have a Material
Adverse Effect.

         4.27 Accuracy of Representations  and Warranties.  No representation or
warranty  by  CCBC,  and no  statement  by CCBC in any  certificate,  agreement,
schedule  or other  document  furnished  in  connection  with  the  transactions
contemplated  by this  Agreement  or the  Merger  Agreements,  contains  or will
contain any untrue  statement of a material  fact or omits or will omit to state
any material fact necessary to make such  representation,  warranty or statement
not misleading to Sierra; provided, however, that information as of a later date
shall be deemed to modify information as of an earlier date.

Section 5.  REPRESENTATIONS AND WARRANTIES OF SIERRA.

         Sierra  represents  and  warrants to CCBC that,  except as set forth in
writing corresponding in number to the appropriate section:

         5.1 Corporate Status and Power to Enter Into Agreements. (i) Bancorp is
a corporation  duly  incorporated,  validly  existing and in good standing under
California  law, and is a registered  bank holding  company under the BHCA, (ii)
subject to the  approval of this  Agreement  and the  transactions  contemplated
hereby by the Commissioner, the FDIC and, unless waived, the FRB, Sierra has all
necessary corporate power to enter into this Agreement and the Merger Agreements
and to carry  out all of the terms  and  provisions  hereof  and  thereof  to be
carried out by it, (iii) Sierra Bank is a California  banking  corporation  duly
licensed by the Commissioner to engage in the commercial banking business as now
conducted by it, and (iv) neither Sierra nor any of its  subsidiaries is subject
to any order of the FRB,  the FDIC,  the  Commissioner  or any other  regulatory
authority  having  jurisdiction  over  its  business  or any of  its  assets  or
properties.  Neither the scope of the business of Sierra nor the location of its
properties  requires it to be licensed to do business in any jurisdictions other
than states of California and Nevada.  Sierra Bank's deposits are insured by the
FDIC to the maximum extent permitted by applicable law and regulation.

         5.2 Articles,  Bylaws, Books and Records. The copies of the Articles of
Incorporation  and Bylaws of Sierra  made  available  to CCBC are  complete  and
accurate  copies  thereof as in effect on the date  hereof.  The minute books of
Sierra contain a complete and accurate record of all meetings of Sierra's Boards
of Directors (and committees thereof) and shareholders.  The corporate books and
records (including  financial  statements) of Sierra fairly reflect the material
transactions  to which Sierra is a party or by which its  properties are subject
or bound, and such books and records have been properly kept and maintained.

         5.3 Compliance With Laws,  Regulations and Decrees.  Sierra (i) has the
corporate  power to own or lease its  properties  and to conduct its business as
currently conducted,  (ii) has complied with, and is not in default of any laws,
regulations,  ordinances,  orders or decrees  applicable  to the  conduct of its
business and the ownership of its  properties,  including but not limited to all
federal  and state laws  (including  but not limited to the Bank  Secrecy  Act),
rules and regulations relating to the offer, sale or issuance of securities, and
the  operation  of a commercial  bank,  other than where such  noncompliance  or
default is not likely to result in a material  limitation  on the conduct of the
business of Sierra or is not likely to otherwise have a material  adverse effect
on  Sierra  taken as a whole,  (iii)  has not  failed  to file  with the  proper
federal, state, local or other authorities any material report or other document
required to be to filed, and (iv) has all approvals,  authorizations,  consents,
licenses,   clearances   and  orders  of,  and  has   currently   effective  all
registrations  with,  all  governmental  and  regulatory  authorities  which are
necessary to the business and operations of Sierra as now being conducted.

         5.4  Capitalization.  As of October 31, 1997,  the  authorized  capital
stock of Sierra  consists of 10,000,000  shares of Sierra  common stock,  no par
value, of which 4,088,659 are duly  authorized,  validly issued,  fully paid and
nonassessable  and currently  outstanding,  9,800,000  shares of preferred stock
none of which is outstanding, 200,000 shares of series A preferred stock none of
which are issued or  outstanding.  Said stock has been issued in compliance with
all  applicable  securities  laws.  There are currently  outstanding  options to
purchase  345,383 shares of Sierra common stock, at a weighted  average exercise
price of $11.56 per share,  issued  pursuant  to its 1988 and 1996 Stock  Option
Plan.  Said options were issued and, upon issuance in accordance  with the terms
of the outstanding  options said shares shall be issued,  in compliance with all
applicable  securities  laws.  Sierra has adopted a Board of Directors  Deferred
Compensation  and Stock Award Plan under which the members of Sierra's  Board of
Directors  can  elect to  defer  earned  director  compensation  and  take  such
compensation  upon retirement from the Board either in the form of Sierra Shares
or in cash. Otherwise, there are no outstanding (i) options,  agreements,  calls
or commitments  of any character  which would  obligate  Sierra to issue,  sell,
pledge,  assign or otherwise  encumber or dispose of, or to purchase,  redeem or
otherwise  acquire,  any Sierra  common  stock or any other  equity  security of
Sierra,  or (ii) warrants or options relating to, rights to acquire,  or debt or
equity  securities  convertible into, shares of Sierra common stock or any other
equity security of Sierra.  The outstanding common stock of Sierra has been duly
and  validly  registered  with the SEC  pursuant  to the 1934 Act, to the extent
required thereunder.

         5.5 Financial Statements, Regulatory Reports. No financial statement or
other document to be provided to CCBC by Sierra under this Agreement,  as of the
date of such document,  contained,  or as to documents to be delivered after the
date hereof,  will contain,  any untrue statement of a material fact, or, at the
date thereof,  omitted or will omit to state a material fact  necessary in order
to make the statements  contained therein,  in light of the circumstances  under
which such statements were or will be made, not misleading;  provided,  however,
that information as of a later date shall be deemed to modify  information as of
any earlier date.  Sierra has filed all material  documents and reports required
to be filed by it with the  FDIC,  the  Commissioner,  the FRB,  the SEC and any
other governmental authority having jurisdiction over its business or any of its
assets or properties. All such reports conform in all material respects with the
requirements   promulgated  by  such  regulatory  agencies.  All  compliance  or
corrective  action relating to Sierra  required by governmental  authorities and
regulatory  agencies having jurisdiction over either Bancorp or Sierra Bank have
been  taken,  including  compliance  with  any  of  the  FRB,  the  FDIC  or the
Commissioner  in their most recent Reports of  Examination.  Sierra's  composite
CAMELS rating in its most recent  Reports of  Examination  is a "1" or a "2" and
its CRA  rating is  "outstanding"  or  "satisfactory'  and  Sierra  has not been
notified  formally or  informally  that such  ratings may be changed by any bank
regulatory  agency  having  authority  over Sierra.  Sierra has not received any
notification,  formally  or  informally,  from any agency or  department  of any
federal, state or local government or any regulatory agency or the staff thereof
(i) asserting that it is not in compliance with any of the statutes, regulations
or ordinances which such government or regulatory  authority  enforces,  or (ii)
threatening   to  revoke  any  license,   franchise,   permit  or   governmental
authorization of Sierra.  Sierra has paid all assessments made or imposed by any
governmental  agency.  Sierra  has  delivered  to  CCBC  copies  of  all  annual
management  letters and opinions,  and has made available to CCBC for inspection
all reviews,  correspondence and other documents in the files of Sierra prepared
by Deloitte & Touche or any other certified public accountant  engaged by Sierra
and delivered to Sierra since December 31, 1996. The financial records of Sierra
have  been,  are being and  shall be  maintained  in all  material  respects  in
accordance with all applicable legal and accounting  requirements  sufficient to
insure that all transactions  reflected  therein are, in all material  respects,
executed in accordance with management's  general or specific  authorization and
recorded in conformity with generally accepted accounting principles at the time
in effect. The data processing equipment,  data transmission equipment,  related
peripheral  equipment  and  software  used by  Sierra  in the  operation  of its
business to generate  and retrieve  its  financial  records are adequate for the
current needs of Sierra.

         5.6  Tax Returns.

         (a) Sierra has  timely  filed all  federal,  state,  county,  local and
foreign tax returns required to be filed by it, including,  without  limitation,
estimated  tax, use tax,  excise tax,  real  property and personal  property tax
reports and returns,  employer's  withholding tax returns, other withholding tax
returns and Federal  Unemployment  Tax Returns,  and all other  reports or other
information  required or  requested  to be filed by each of them,  and each such
return,  report or other  information was, when filed,  complete and accurate in
all material  respects.  Sierra has paid all taxes, fees and other  governmental
charges,  including  any interest and penalties  thereon,  when they have become
due,  except  those that are being  contested  in good  faith,  which  contested
matters have been disclosed to CCBC.  Except as set forth below,  neither Sierra
nor  any of its  subsidiaries  has  been  requested  to give  or has  given  any
currently  effective  waivers  extending  the  statutory  period  of  limitation
applicable  to any tax  return  required  to be filed by  either of them for any
period. Except as set forth below, there are no claims pending against Sierra or
any of its subsidiaries for any alleged  deficiency in the payment of any taxes,
and Sierra does not know of any pending or threatened audits,  investigations or
claims for unpaid taxes or relating to any liability in respect of any taxes.

         (b) No consent has been filed  relating  to Sierra  pursuant to Section
341(f) of the IRC.

         5.7 Material Adverse Change.  Except as heretofore disclosed in writing
by Sierra to CCBC,  since September 30, 1997, there has been no material adverse
change in the  business,  assets,  licenses,  permits,  franchises,  results  of
operations  or  financial  condition  of Sierra  (whether or not in the Ordinary
Course).

         5.8 Legal Actions and  Proceedings.  Except as previously  disclosed to
CCBC in writing, Sierra is not a party to, or so far as either of them is aware,
threatened  with, and to Sierra's  knowledge,  there is no reasonable basis for,
any legal action or other  proceeding  or  investigation  before any court,  any
arbitrator of any kind or any  government  agency,  and Sierra is not subject to
any potential  adverse claim,  the outcome of which could involve the payment or
receipt  by Sierra of any  amount in excess of  $200,000,  unless an  insurer of
Sierra  has  agreed  to  defend  against  and pay the  amount  of any  resulting
liability  without  reservation,  or,  if any  such  legal  action,  proceeding,
investigation  or claim  will not  involve  the  payment by Sierra of a monetary
amount,  which  could  materially  adversely  affect  Sierra or its  business or
property or the transactions contemplated hereby. Sierra has no knowledge of any
pending or threatened  claims or charges under the Community  Reinvestment  Act,
before the Equal Employment Opportunity Commission, the California Department of
Fair Housing & Economic Development,  the California Unemployment Appeals Board,
or any human relations commission.  There is no labor dispute, strike, slow-down
or stoppage pending or, to the knowledge of Sierra, threatened against Sierra.

         5.9  Execution and Delivery of the Agreement.

         (a) The  execution  and  delivery  of this  Agreement  have  been  duly
authorized  by the Boards of  Directors  of Sierra and,  when the  Merger,  this
Agreement,  the Bank Merger  Agreement and the Agreement and Plan of Merger have
been or will  be duly  approved  by the  affirmative  vote of the  holders  of a
majority  of the  outstanding  shares of  Bancorp  common  stock at a meeting of
shareholders  duly called and held,  the Merger,  this  Agreement and the Merger
Agreements will be duly and validly authorized by all necessary corporate action
on the part of Sierra.

         (b) This  Agreement  has been duly executed and delivered by Sierra and
(assuming  due  execution  and  delivery  by CCBC)  constitutes,  and the Merger
Agreements,  upon  execution  and delivery by Sierra (and assuming due execution
and delivery by CCBC) will constitute,  legal and binding  obligations of Sierra
in accordance with its terms.

         (c) The  execution  and  delivery by Sierra of this  Agreement  and the
Merger  Agreements and the consummation of the  transactions  herein and therein
contemplated  (i) do not violate any provision of the Articles of  Incorporation
or Bylaws of Sierra or, to Sierra's knowledge, any provision of federal or state
law  or any  governmental  rule  or  regulation  (assuming  (A)  receipt  of the
Government  Approvals,  (B) due registration of the Sierra Shares under the 1933
Act, (C) receipt of appropriate  permits or approvals under state  securities or
"blue sky"  laws,  and (D)  accuracy  of the  representations  of CCBC set forth
herein),  and (ii) to  Sierra's  knowledge,  do not  require  any consent of any
person  under,  conflict  with or  result  in a breach  of,  or  accelerate  the
performance  required  by any of the terms of,  any  material  debt  instrument,
lease, license, covenant,  agreement or understanding to which Sierra is a party
or by which it is bound or any  order,  ruling,  decree,  judgment,  arbitration
award or  stipulation  to which  Sierra  is  subject,  or  constitute  a default
thereunder  or result in the  creation of any lien,  claim,  security  interest,
encumbrance,  charge,  restriction  or  right  of any  third  party  of any kind
whatsoever upon any of the properties or assets of Sierra.

         5.10 No  Undisclosed  Liabilities.  Except for items for which reserves
have been established in the audited balance sheets of Sierra as of December 31,
1996,  Sierra has not incurred or discharged,  and is not legally obligated with
respect  to  any  indebtedness,  liability  (including,  without  limitation,  a
liability arising out of an indemnification, guarantee, hold harmless or similar
arrangement) or obligation (accrued or contingent, whether due or to become due,
and whether or not subordinated to the claims of its general  creditors),  which
would have a material  effect on the capital or earnings of Sierra other than as
a result of  operations  in the Ordinary  Course  after such date.  No agreement
pursuant to which any loans or other  assets have been or will be sold by Sierra
entitled  the buyer of such  loans or other  assets,  unless  there is  material
breach  of a  representation  or  covenant  by the  seller,  to cause  Sierra to
repurchase  such loan or other  asset or the buyer to pursue  any other  form of
recourse  against  Sierra.  Sierra has not knowingly made and shall not make any
representation or covenant in any such agreement that contained or shall contain
any  untrue  statement  of a  material  fact or omitted or shall omit to state a
material fact necessary in order to make the statements  contained  therein,  in
light of the  circumstances  under which such  representations  and/or covenants
were made or shall be made, not  misleading.  Other than regular  quarterly cash
dividends by Sierra, no cash, stock or other dividend or any other  distribution
with respect to the stock of Sierra has been  declared,  set aside or paid,  nor
have any shares of the stock of Sierra been  purchased,  redeemed  or  otherwise
acquired, directly or indirectly, by Sierra since December 31, 1996.

         5.11 No Material  Environmental  Liabilities.  To  Sierra's  knowledge,
Sierra does not own,  possess or have a  collateral  or  contingent  interest or
purchase  option in any properties or other assets which contain or have located
within or thereon any hazardous or toxic waste material or substance  unless the
location of such hazardous or toxic waste material or other substance or its use
thereon conforms in all material respect with all federal, state and local laws,
rules,  regulations  or other  provisions  regulating the discharge of materials
into the  environment  the  liability  of  remediation  for which  would cause a
material adverse change in the capital or earnings of Sierra.

         5.12 No Material  Liabilities  Under ERISA. No  governmental  agency or
claimant or representative of such claimant have alleged a material violation of
ERISA by Sierra the liability for which, if adversely  determined,  would result
in a material adverse change in the capital or earnings of Sierra.

         5.13  Retention  of  Broker  or  Consultant.   Other  than  NationsBanc
Montgomery Securities, Inc., no broker, agent, finder, consultant or other party
(other than legal,  compliance,  loan auditors and accounting advisors) has been
retained  by  Sierra  or is  entitled  to be paid  based  upon  any  agreements,
arrangements  or  understandings  made by Sierra in  connection  with any of the
transactions   contemplated   by  this  Agreement  or  the  Merger   Agreements.
NationsBanc  Montgomery  Securities,  Inc. will render an opinion  regarding the
fairness of the Merger from a financial point of view.

         5.14 Loan Loss Reserves.  To the knowledge of Sierra's management,  the
allowance for loan losses in the Sierra balance sheet dated  September 30, 1997,
and as of the Effective  Date are and will be adequate in all material  respects
under the  requirements of all applicable state and federal laws and regulations
to provide for possible loan losses on  outstanding  loans,  net of  recoveries,
including  compliance with the comments of the FDIC in its most recent Report of
Examination.

         5.15  Information in Sierra  Registration  Statement.  The  information
pertaining  to Sierra  which has been or will be  furnished  for or on behalf of
Sierra for  inclusion  in the Sierra  Registration  Statement or the Joint Proxy
Materials,  or in the  Applications,  does not and will not  contain  any untrue
statement of any material  fact or omit or will 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 are made, not misleading;  provided,
however,  that information of a later date shall be deemed to modify information
as of an earlier date. All financial  statements of Sierra included in the Joint
Proxy  Materials  will present  fairly the  financial  condition  and results of
operations of Sierra at the dates and for the periods covered by such statements
in accordance with generally accepted accounting principles consistently applied
throughout the periods covered by such statements.  Sierra shall promptly advise
CCBC in writing if prior to the Effective Date Sierra shall obtain  knowledge of
any  facts  that  would  make it  necessary  to amend  the  Sierra  Registration
Statement,  the Joint Proxy Materials or any  Application,  or to supplement the
prospectus,  in order to make the statements therein not misleading or to comply
with applicable law.

         (a) Pooling of Interests.  Sierra knows of no reason  relating to it or
any of its  subsidiaries  which would  reasonably  cause it to believe  that the
Merger  will not  qualify as a pooling of  interests  for  financial  accounting
purposes.

         5.16  Equity   Interest  in  Any  Entity.   Except  as  collateral  for
outstanding  loans held in its loan  portfolio and its ownership of Sierra Bank,
Bancorp does not own,  directly or indirectly,  any equity interest in any bank,
corporation or other entity.

         5.17 Loans.  Sierra has  disclosed to CCBC in writing prior to the date
hereof, and will promptly inform CCBC of the amounts of all loans, leases, other
extensions of credit or commitments, or other interest-bearing assets of Sierra,
that have been  classified  as of the date hereof or  hereafter  by any internal
bank examiner or any bank regulatory  agency or the Commissioner as "Other Loans
Specially Mentioned," "Special Mention,"  "Substandard,"  "Doubtful," "Loss," or
words of  similar  import  in the case of loans  (or  that  would  have  been so
classified,  in the case of other interest-bearing assets, had they been loans).
Sierra has  furnished  and will  continue  to furnish to CCBC true and  accurate
information concerning the loan portfolio of Sierra, and no material information
with respect to the loan  portfolio has been or will be withheld from CCBC.  All
loans and  investments  of Sierra  are  legal,  valid  and  binding  obligations
enforceable  in  accordance  with its terms and are not subject to any  setoffs,
counterclaims  or disputes  (subject to applicable  bankruptcy,  insolvency  and
similar  laws  affecting   creditors'  rights  generally  and  subject,   as  to
enforceability,  to equitable  principles of general  applicability),  except as
disclosed to CCBC in writing or reserved  for in the balance  sheet of Sierra as
of September  30, 1997,  and were duly  authorized  under and made in compliance
with applicable federal and state laws and regulations. Sierra does not have any
extensions of credit,  investments,  guarantees,  indemnification  agreements or
commitments  for the same  (including  without  limitation  commitments to issue
letters of credit, to create acceptances,  or to repurchase securities,  federal
funds or other assets)  other than those  documented on the books and records of
Sierra.

         5.18 Derivatives Contracts; Structured Notes; Etc. Except as previously
disclosed,  Sierra is not a party to nor has it agreed to enter into an exchange
traded or  over-the-counter  equity,  interest rate,  foreign  exchange or other
swap, forward,  future,  option, cap, floor or collar or any other contract that
is not included on the balance  sheet and is a derivatives  contract  (including
various combinations  thereof) (each, a "Derivatives  Contract") nor does it own
securities that (1) are referred to generically as "structured notes," high risk
mortgage  derivatives,"  "capped  floating rate notes" or "capped  floating rate
mortgage  derivatives" or (2) are likely to have changes in value as a result of
interest or exchange rate changes that  significantly  exceed normal  changes in
value  attributable  to  interest  or exchange  rate  changes,  except for those
Derivatives Contracts and other instruments legally purchased or entered into in
the  ordinary  course  of  business,  consistent  with  safe and  sound  banking
practices and  regulatory  guidelines,  and  previously  disclosed in writing to
CCBC. All of such Derivatives  Contracts or other  instruments are legal,  valid
and binding  obligations of Sierra  enforceable  in accordance  with their terms
(except as  enforcement  may be limited by general  principles of equity whether
applied in a court of law or a court of equity and by bankruptcy, insolvency and
similar laws affecting  creditors'  rights and remedies  generally),  and are in
full force and effect. Sierra has duly performed in all material respects all of
their  material  obligations  thereunder to the extent that such  obligations to
perform  have  accrued;  and,  to  Sierra's  knowledge,  there are no  breaches,
violations  or  defaults  or  allegations  or  assertions  of such by any  party
thereunder  which would have or would  reasonably be expected to have a Material
Adverse Effect.

         5.19 Accuracy of Representations  and Warranties.  No representation or
warranty by Sierra,  and no statement by Sierra in any  certificate,  agreement,
schedule  or other  document  furnished  in  connection  with  the  transactions
contemplated  by this  Agreement  or the  Merger  Agreements,  contains  or will
contain any untrue  statement of a material  fact or omits or will omit to state
any material fact necessary to make such  representation,  warranty or statement
not misleading to CCBC; provided,  however,  that information as of a later date
shall be deemed to modify information as of an earlier date.

Section 6.  SECURITIES ACT OF 1933; SECURITIES EXCHANGE ACT OF 1934.

         6.1  Preparation  and Filing of  Registration  Statement.  Sierra shall
promptly  prepare  and  file  with  the  SEC a  registration  statement  on  the
appropriate form (the "Sierra Registration Statement") under and pursuant to the
provisions of the 1933 Act for the purpose of  registering  the Sierra Shares to
be issued in the Acquisition. Sierra and CCBC shall promptly prepare joint proxy
materials  (the "Joint  Proxy  Materials")  for the purpose of  submitting  this
Agreement,  the  Bank  Merger  and  the  Agreement  and  Plan of  Merger  to the
respective  shareholders of Sierra and CCBC for approval.  Sierra and CCBC shall
cooperate  in all  reasonable  respects  with regard to the  preparation  of the
Sierra  Registration  Statement and the Joint Proxy  Materials.  The Joint Proxy
Materials  in  definitive  form are  expected to serve as the  prospectus  to be
included  in the  Sierra  Registration  Statement.  Sierra  and CCBC  shall each
provide  promptly to the other such  information  concerning  its  business  and
financial  condition and affairs as may be required or appropriate for inclusion
in the Sierra  Registration  Statement or the Joint Proxy  Materials,  and shall
cause its  counsel  and  auditors  to  cooperate  with the  other's  counsel and
auditors in the preparation of the Sierra  Registration  Statement and the Joint
Proxy Materials.

         6.2  Effectiveness  of  Registration  Statement  and Listing of Shares.
Sierra  and CCBC  shall use their  commercially  reasonable  efforts to have the
Sierra Registration Statement and any amendments or supplements thereto declared
effective under the 1933 Act as soon as  practicable,  and thereafter CCBC shall
distribute the Proxy Materials to holders of its common stock in accordance with
applicable laws. Sierra shall use commercially  reasonable  efforts to cause the
Sierra  Shares  issued to effect the Merger to be  approved  for  listing on the
Nasdaq  National Market System when such Sierra Shares are issued to Bancshares'
shareholders.

         6.3 Sales and Resales of Common Stock.  Sierra shall not be required to
maintain the effectiveness of the Sierra Registration  Statement for the purpose
of sale or resale of the Sierra Shares by any person.

         6.4  Rule 145 and  Related  Matters.  At  Sierra's  option,  securities
representing  Sierra Shares issued to  "affiliates",  as that term is defined in
the 1933 Act, of CCBC (as  determined  by counsel to Sierra and CCBC) under Rule
145 of the  Rules and  Regulations  under the 1933 Act  pursuant  to the  Merger
Agreements  will be subject to stop transfer  orders and will bear a restrictive
legend in substantially the following form:

                  "The  Securities  Represented  by this  Certificate  Have been
                  Issued in a Transaction  to Which Rule 145  Promulgated  under
                  the Securities  Act of 1933, as Amended,  Applies and May Only
                  Be  Sold or  Otherwise  Transferred  in  Compliance  with  the
                  Requirements   of  Rule  145  or  Pursuant  to  an   Effective
                  Registration  Statement  under  Said  Act or in a  Transaction
                  Which,  in the Opinion of Counsel  Satisfactory to the Issuer,
                  satisfies an Exemption from Such Registration."

Should any opinion of counsel  described in the foregoing  legend  indicate that
the legend and any stop transfer order then in effect with respect to the shares
may be removed,  Sierra will upon request substitute  unlegended  securities and
remove any stop transfer orders.

Section 7.  CONDITIONS TO THE OBLIGATIONS OF SIERRA.

         The  obligations  of Sierra  under this  Agreement  are, at its option,
subject  to  fulfillment  at or  prior  to the  Effective  Date  of  each of the
following conditions; provided, however, that any one or more of such conditions
may be waived by the Board of Directors of Sierra at any time at or prior to the
Effective Date:

         7.1 Representations and Warranties.  The representations and warranties
of CCBC in Section 4 hereof shall be true and correct in all  material  respects
on  and  as of  the  Effective  Date,  with  the  same  effect  as  though  such
representations and warranties had been made on and as of such date except as to
any representation or warranty which specifically relates to an earlier date.

         7.2  Compliance  and  Performance  Under  Agreement.  CCBC  shall  have
performed and complied in all material respects with all terms of this Agreement
and the Merger Agreements  required to be performed or complied with by it at or
prior to the Effective Date.

         7.3 Material  Adverse Change.  No materially  adverse change shall have
occurred  since  September  30, 1997, in the  business,  financial  condition or
results  of  operations  of CCBC and CCBC  shall not be a party to or, so far as
CCBC is aware,  threatened  with, and to CCBC's knowledge there is no reasonable
basis for, any legal action or other proceeding before any court, any arbitrator
of any kind or any Government  agency if, in the reasonable  judgment of Sierra,
such legal action or proceeding could  materially  adversely affect CCBC, or its
business, financial condition or results of operations.

         7.4 Approval of Agreement.  The Merger,  this  Agreement and the Merger
Agreements  shall have been duly approved by the affirmative vote of the holders
of a majority of the outstanding shares of Sierra Shares and CCBC Shares.

         7.5 Officer's  Certificate.  Sierra shall have received a  certificate,
dated the Effective Date, signed on behalf of CCBC by the respective  Presidents
and Chief  Financial  Officers  of  Bancshares  and CPB to the  effect  that the
conditions in Sections 7.1-7.4 have been satisfied.

         7.6  Opinion  of  Counsel.  CCBC shall have  delivered  to Sierra  such
documents as may  reasonably  be requested by Sierra to evidence  compliance  by
CCBC with the provisions of this Agreement and the Merger Agreements,  including
an opinion of its counsel in a form substantially as set forth on Exhibit 7.6.

         7.7 Absence of Legal Impediment.  On the Effective Date, there shall be
an absence of: (a) any suit,  action or  proceeding,  or order  against  CCBC or
Sierra  with  respect  to  any  part  of  this  Agreement,  or  the  Merger,  or
challenging,  enjoining,  or otherwise  affecting the consummation of the Merger
which,  in the opinion of counsel for Sierra,  materially  affects the Merger or
the consummation of this Agreement;  or (b) any pending or threatened  action or
proceeding  by  the  United  States  Department  of  Justice  or  other  federal
governmental agency seeking to enjoin,  prohibit or otherwise impede the Merger;
or (c) a banking  moratorium  or other  suspension  of  payment  by banks in the
United States or any general  limitation on extension of credit by lending banks
in the United States.

         7.8 Effectiveness of Registration  Statement.  The Sierra  Registration
Statement and any amendments or supplements  thereto shall have become effective
under  the  1933  Act.  No  stop  order  suspending  the  effectiveness  of such
Registration  Statement  shall be in effect and no proceedings  for such purpose
shall  have  been  initiated  or  threatened  by or  before  the SEC.  All state
securities  and "blue sky"  permits or  approvals  required  to  consummate  the
transactions contemplated by this Agreement and the Merger Agreements shall have
been received.

         7.9 Government Approvals.  All Government Approvals shall be in effect,
and all conditions or requirements prescribed by law or by any such Governmental
Approval  shall  have been  satisfied;  provided,  however,  that no  Government
Approval  shall  be  deemed  to have  been  received  if it  shall  require  the
divestiture  or  cessation  of any  of  the  present  businesses  or  operations
conducted by either of the parties hereto or shall impose any other condition or
requirement, which Sierra in its reasonable judgment shall deem to be materially
burdensome  (in which case Sierra shall promptly  notify CCBC).  For purposes of
this  Agreement no condition  shall be deemed to be  "materially  burdensome" if
such condition does not materially  differ from conditions  regularly imposed by
the FRB, the Commissioner,  or FDIC in orders approving transactions of the type
contemplated by this Agreement and compliance with such condition would not:

         (a)  require the taking of any action  inconsistent  with the manner in
which Sierra or CCBC has conducted its business previously;

         (b)  have a  material  adverse  effect  upon  the  business,  financial
condition or results of operations of Sierra or CCBC; or

         (c) preclude  satisfaction  of any of the conditions to consummation of
the transactions contemplated by this Agreement.

         7.10 Tax  Opinion.  Sierra and CCBC shall have  received  an opinion of
counsel or accountants  satisfactory to both parties, subject to assumptions and
exceptions normally included,  in form and substance reasonably  satisfactory to
both parties,  substantially to the effect that under federal income tax law and
California income and franchise tax law:

         (a) The Merger will qualify as a "reorganization" within the meaning of
Internal Revenue Code Section 368(a)(1)(A);

         (b) Except for any cash received in lieu of any  fractional  share,  no
gain or loss will be  recognized  by holders of CCBC Shares who  receive  Sierra
Shares in exchange for the CCBC Shares which they hold;

         (c) The  holding  period of Sierra  Shares  exchanged  for CCBC  Shares
(including any fractional  share prior to its conversion into cash) will include
the holding period of the CCBC Shares for which they are exchanged, assuming the
shares of CCBC Shares are capital  assets in the hands of the holder  thereof at
the Effective Date;

         (d) The basis of the Sierra Shares received in the exchange will be the
same as the basis of the CCBC  Shares  for which  they are  exchanged,  less any
basis attributable to fractional shares for which cash is received;

         (e) No  gain  or  loss  will  be  recognized  by  Bancshares  or CPB in
connection with the Merger or the Bank Merger;

         (f) Any cash received by a shareholder  of CCBC in lieu of a fractional
share  will,  to the extent  such share was a capital  asset in the hands of the
CCBC  shareholder,  result  in  recognition  of  capital  gain  or  loss by such
shareholder  measured by the difference  between the cash received and the basis
of such fractional share;

         (g) Provided the options to buy Sierra  Shares are not actively  traded
on an established  market,  no gain or loss will be recognized by the holders of
nonqualified  options to buy CCBC Shares upon the  conversion  of those  options
into  nonqualified  options  to buy  Sierra  Shares  under  the same  terms  and
conditions as in effect immediately prior to the proposed transaction;

         (h) No gain or loss will be  recognized  by the  holders  of  incentive
stock  options to buy CCBC  Shares upon the  conversion  of those  options  into
incentive stock options to buy Sierra Shares under the same terms and conditions
as in effect immediately prior to the proposed transaction;

         (i) A CCBC  shareholder  who dissents to the  transaction  and receives
cash in  exchange  for the  shareholder's  CCBC Shares will be treated as having
received a distribution in redemption of the shareholder's CCBC Shares,  subject
to the provisions and  limitations  of Section 302.  Where,  as a result of such
distribution,  the  shareholder  owns no Sierra  Shares,  either  directly or by
reason of Section 318, and provided the CCBC Shares were capital  assets in such
shareholder's  hands,  the redemption  will result in the recognition of capital
gain or loss by such shareholder  measured by the difference  between the amount
of cash received and the adjusted basis of the CCBC Shares surrendered; and

         (j) No gain or loss will be recognized  (and no amount will be included
in  income)  by a holder of CCBC  convertible  debentures  (whether  or not such
holder also holds CCBC Shares) upon the assumption of such debentures by Sierra.

         7.11 Unaudited Financials.  Not later than the Determination Date, CCBC
shall  have  furnished  Sierra a copy of its most  recently  prepared  unaudited
consolidated  financial  statements for the period beginning January 1, 1997 and
ending the month end immediately  preceding the Determination Date,  including a
balance sheet and statement of income of CCBC for that period.

         7.12 Rule 145 Undertaking.  Each director,  executive officer and other
person who is an "affiliate" (for purposes of Rule 145 under the Securities Act)
of CCBC shall have delivered to Sierra, as soon as practicable after the date of
this  Agreement,  and  prior to the date of the  shareholder  meeting  called by
Bancshares  to  approve  this  Agreement,  a written  agreement,  in the form of
Exhibit 7.12 hereto,  providing that such person will not sell, pledge, transfer
or otherwise  dispose of any Sierra Shares to be received by such "affiliate" in
the  Merger,  except  in  compliance  with  the  applicable  provisions  of  the
Securities Act and the rules and  regulations  thereunder.  Notwithstanding  any
other  provision of this  Agreement,  no certificate  for Sierra Shares shall be
delivered in exchange for CCBC Shares held by any such "affiliate" who shall not
have executed and delivered such an agreement.

         7.13 Closing  Documents.  Sierra shall have received such  certificates
and other closing documents as counsel for Sierra shall reasonably request.

         7.14 Consents. CCBC shall have received, or Sierra shall have satisfied
itself that CCBC will receive,  all consents of other parties to and required by
material mortgages, notes, leases, franchises,  agreements, licenses and permits
applicable to CCBC, in each case in form and substance  reasonably  satisfactory
to Sierra, and no such consent or license or permit shall have been withdrawn or
suspended.

         7.15 Shareholder  Agreements.  All directors of CCBC shall have entered
into a  shareholder's  agreement  in the form  attached  hereto as Exhibit  7.15
contemporaneously   with  the   execution  of  this   Agreement  by  which  such
shareholders  agree  to  vote  their  shares  and any  shares  over  which  such
shareholders  have voting authority in favor of the Merger and further agreeing,
to the extent  permitted by law and the bylaws of CCBC,  to vote in favor of the
Merger by consent solicitation.

         7.16 Noncompetition  Agreements. All existing non-employee directors of
CCBC shall have  entered  into a written  agreement  not to engage in a business
competitive  to that of Sierra or CCBC in Solano,  Sacramento  and Contra  Costa
Counties  for a period  of three  years  from the  closing  of the  Acquisition.
Restricted  activities  shall include  participation  in organizing or any stock
ownership in a new bank,  acquisition of equity securities of any competing bank
that has operations within the aforementioned counties with less than $5 billion
of assets or acting as a director of any competing  institution within such area
for such period; provided that this provision shall not preclude the acquisition
of such  securities if the securities so acquired do not exceed in the aggregate
the lesser of $50,000 in market  value at the time of  acquisition  or 1% of the
outstanding equities of the competing bank.

         7.17  Fairness  Opinion.  The Board of Directors of Bancorp  shall have
received an opinion of its financial advisor to the effect that the terms of the
Merger  are  fair,   from  a  financial  point  of  view,  to  Bancorp  and  its
shareholders.

         7.18 Pooling of Interests.  Prior to the Effective  Date,  Sierra shall
have  received a written  opinion  from  Deloitte & Touche  that the Merger will
qualify  for  pooling  of  interests   accounting   treatment.   In  making  its
determination that the Merger will qualify for such treatment, Deloitte & Touche
shall be entitled  to assume  that cash will be paid with  respect to all shares
held of record by any holder of dissenting shares.

         7.19  Resignations.  Sierra shall have received  resignations of all of
the directors of CCBC,  which  resignations  shall be effective on the Effective
Date.

Section 8.  CONDITIONS TO THE OBLIGATIONS OF CCBC.

         The  obligations  of CCBC  under this  Agreement  are,  at its  option,
subject  to the  fulfillment  at or prior to the  Effective  Date of each of the

may be waived by the Board of Directors of Bancshares at any time at or prior to
the Effective Date:

of Sierra in Section 5 hereof shall be true and correct in all material respects

representations and warranties had been made on and as of such date except as to
any representation or warranty which specifically related to an earlier date.

         8.2  Compliance  and  Performance  Under  Agreement.  Sierra shall have
performed  and complied in all material  respects  with all of the terms of this
Agreement and the Merger Agreements required to be performed or complied with by
them at or prior to the Effective Date.

         8.3 Material  Adverse Change.  No materially  adverse change shall have
occurred since September 30, 1997, in the business, financial condition, results
of operations or properties of Sierra and its subsidiaries taken as a whole, and
Sierra  shall  not be  engaged  in,  or a party to or so far as Sierra is aware,
threatened with, and to Sierra's knowledge no grounds shall exist for, any legal
action or other  proceeding  before any court, any arbitrator of any kind or any
government  agency if, in the reasonable  judgment of CCBC, such legal action or
proceeding could materially  adversely affect Sierra or its business,  financial
condition, results of operations or assets.

         8.4 Approval of Agreement.  The Merger,  this  Agreement and the Merger
Agreements  shall have been duly approved by the affirmative vote of the holders
of a majority of the outstanding Sierra Shares and CCBC Shares.

         8.5  Officer's  Certificate.  CCBC shall have  received a  certificate,
dated  the  Effective  Date,  signed  on  behalf  of  Sierra  by the  respective
Presidents and Chief Financial  Officers of Bancorp and Sierra Bank,  certifying
to the fulfillment of the conditions stated in Sections 8.1-8.4 hereof.

         8.6  Opinion  of  Counsel.  Sierra  shall have  delivered  to CCBC such
documents  as may  reasonably  be requested  by CCBC to evidence  compliance  by
Sierra  with  the  provisions  of  this  Agreement  and the  Merger  Agreements,

one or more of the  Governmental  Approvals or if Sierra shall be  contesting in
good  faith  any  litigation   which  seeks  to  prevent   consummation  of  the

determines at any time during the two  business-day  period  commencing  one day
after the Determination Date, if the Market Value is less than $21.59; provided,
however,  if CCBC  elects to exercise  its  termination  right  pursuant to this
Section 11(h), it shall give prompt written notice to Sierra (provided that such
notice  of  election  to  terminate  may be  withdrawn  at any time  within  the
aforementioned  two  business-day  period),  in  which  case,  within  such  two
business-day period,  commencing on the day after receipt of such notice, Sierra
shall have the option of  adjusting  the  Exchange  Ratio to a number equal to a
quotient  (rounded to the nearest ten  thousandth),  the  numerator  of which is
$25.00 and the  denominator  of which is the Market  Value.  If Sierra  makes an
election  contemplated by the preceding  sentence,  it shall give prompt written
notice to CCBC of such  election and the revised  Exchange  Ratio,  whereupon no
termination  shall have  occurred  pursuant to this  Section and this  Agreement
shall  remain in effect in  accordance  with its terms  (except as the  Exchange
Ratio shall have been so  modified),  and any  references  in this  Agreement to
shall have been so modified),  and any references in this Agreement to "Exchange
Ratio" shall  thereafter  be deemed to refer to the  Exchange  Ratio as adjusted
pursuant to this Section.

         11.3 Notice of Termination.  The power of termination  hereunder may be

the other party.

         11.4  Breach of  Obligations.  If there has been a  material  breach by

to  terminate  this  Agreement  upon written  notice to the other party.  In any
event,  the  nondefaulting  party shall have no  obligation  to  consummate  any
transaction  or take any further  steps  toward such  consummation  contemplated
hereunder until such breach is cured.

         11.5  Termination and Expenses.

         (a) If this  Agreement is  terminated  for any reason,  the Bank Merger
Agreement and the Agreement  and Plan of Merger shall  automatically  terminate.
Termination of this Agreement  shall not terminate or affect the  obligations of
the  parties  to pay  expenses  as  provided  in  Section  10, to  maintain  the
confidentiality of the other party's information  pursuant to Section 3.1(f), or
the provisions of this Section 11.5 or of Sections 12.1-12.7.

         (b) If this  Agreement  is  terminated  pursuant to Section  11.2(d) or

amount  indicated  shall be  deemed  consideration  or  liquidated  damages  for
expenses  incurred  and the  lost  opportunity  cost  for  time  devoted  to the
transactions contemplated by this Agreement, provided, however, each party shall
remain liable for expenses as set forth in Section 10.

                          AGREEMENT AND PLAN OF MERGER



         THIS AGREEMENT AND PLAN OF MERGER, dated as of ____________, 19__ (this
"Merger  Agreement"),  is  made  and  entered  into  by and  between  California
Community Bancshares Corporation, a Delaware corporation ("Seller") and
SierraWest Bancorp, a California corporation ("Buyer").

                             W I T N E S S E T H:

         A. The Boards of Directors of Buyer and Seller have approved,  and deem
it advisable  and in the best  interests of Buyer,  Seller and their  respective
shareholders, that Buyer and Seller consummate the business transaction provided
for herein in which Seller would merge with and into Buyer (the "Merger").

         B. Buyer and Seller have entered into an Plan of Acquisition and Merger
dated as of ______________,  19__ (the "Plan"),  providing,  among other things,
for the execution and filing of this Merger  Agreement and the  consummation  of
the Merger.

         NOW, THEREFORE,  in consideration of the promises and mutual agreements
contained in this Merger Agreement,  the parties to this Merger Agreement hereby
agree that  Seller  shall be merged with and into Buyer in  accordance  with the
provisions of the laws of the State of California and the State of Delaware upon
the terms and subject to the conditions set forth as follows:

Section 1.  The Merger.

         1.1 Effective  Time. On  _____________,  1998, upon the filing with the
California  Secretary  of State of a duly  executed  counterpart  of this Merger
Agreement  with the  officers'  certificates  prescribed  by Section 1103 of the
California  General  Corporation Law attached  thereto,  the Merger shall become
effective. The effective time of the Merger on the Effective Date shall be 12:01
a.m., Pacific Standard Time.

         1.2 Effect of the Merger. On the Effective Date, Seller shall be merged
with and into Buyer and the separate corporate  existence of Seller shall cease.
Buyer shall be the surviving  corporation  (the "Surviving  Corporation") in the
Merger. It shall thereupon  succeed,  without other transfer,  to all rights and
properties of, and shall be subject to all the debts and  liabilities of, Seller
and the separate  existence of Buyer as a California  corporation,  with all its
purposes,  objects,  rights,  powers,  privileges and franchises  shall continue
unaffected and unimpaired by the Merger.

Section 2.  Corporate Governance Matters.

         2.1 From and after the Effective Date and until  thereafter  amended as
provided  by law:  (a) the  Articles  of  Incorporation  of Buyer  as in  effect
immediately prior to the Effective Date shall be and continue to be the Articles
of Incorporation of the Surviving Corporation; and (b) the Bylaws of Buyer as in
effect  immediately  prior to the Effective Date shall be and continue to be the
Bylaws of the Surviving Corporation.

         2.2  Subject  to the  provisions  of Section  1.4 of the Plan,  (a) the
directors  of the  Surviving  Corporation  shall  be those  persons  who are the
directors of Buyer immediately prior to the Effective Date; and (b) the officers
of the  Surviving  Corporation  shall be those  persons who are the  officers of
Buyer at the Effective Date.

Section 3.  Conversion of Shares.

         3.1 Conversion of Seller Shares. As of the Effective Date, by virtue of
the Merger and without any action on the part of the holder of the common  stock
of  Seller,  [par value  $.10 per  share] (a  "Seller  Share" or "Seller  Common
Stock"):

         (a) Each issued and  outstanding  Seller Share  (other than  fractional
shares,  or any shares as to which dissenters'  rights have been perfected,  but
including  any  shares  issued  pursuant  to the  Rights  Agreement),  shall  be
converted  into ______ shares of the common stock,  without par value,  of Buyer
("Buyer Common Stock" or a "Buyer Share").

         (b) From and after the  Effective  Date,  the  holders of  certificates
formerly  representing Seller Shares shall cease to have any rights with respect
thereto  other than any  dissenters'  rights  they have  perfected  pursuant  to
Section 262 of the General Corporation Law of the State of Delaware.

         (c) On the  Effective  Date,  all shares of Seller Common Stock held in
the treasury of Seller or owned  beneficially  by any subsidiary of Seller other
than in a fiduciary capacity or in connection with a debt previously  contracted
and all shares of Seller  Common Stock owned by Buyer or owned  beneficially  by
any subsidiary of Buyer other than in a fiduciary capacity or in connection with
a debt  previously  contracted  shall be  canceled  and no cash,  stock or other
property shall be delivered in exchange therefor.

         3.2 Fractional Shares.  Notwithstanding  any other provision hereof, no
fractional  shares of Buyer  Common  Stock  shall be issued to holders of Seller
Shares.  In lieu thereof,  each such holder entitled to a fraction of a share of
Buyer Common Stock shall receive, at the time of surrender of the certificate or
certificates  representing  such holder's Seller Shares, an amount in cash equal
to the market value per share of the Common Stock of Buyer, calculated by taking
the average of the closing  price quoted on the Nasdaq,  as reported in The Wall
Street Journal,  for each of the twenty  consecutive  trading days prior to five
trading days prior to the Effective  Date,  rounded to 4 decimal places (whether
or not there were any trades in Buyer Common Stock on such days),  multiplied by
the  fraction of a share of Buyer  Common  Stock to which such holder  otherwise
would be entitled. No such holder shall be entitled to dividends, voting rights,
interest on the value of, or any other rights in respect of, a fractional share.

         3.3  Surrender of Seller Shares.

         (a)   Prior   to   the    Effective    Date,    Buyer   shall   appoint
____________________________,  or its  successor,  or any  other  bank or  trust
company  mutually  acceptable  to Seller  and  Buyer,  as  exchange  agent  (the
"Exchange  Agent") for the purpose of exchanging  certificates  representing the
Buyer Common Stock,  and at and after the Effective Date,  Buyer shall issue and
deliver to the Exchange Agent certificates  representing the Buyer Common Stock,
as shall be required to be  delivered  to holders of Seller  Shares  pursuant to
Section 3.1 of this Merger Agreement. As soon as practicable after the Effective
Date,  each holder of Seller  Shares  converted  pursuant to Section  3.1,  upon
surrender  to the  Exchange  Agent of one or more  certificates  for such Seller
Shares for cancellation,  along with duly executed  transmittal  materials to be
mailed  after the  Effective  Date by the  Exchange  Agent,  will be entitled to
receive a  certificate  representing  the number of shares of Buyer Common Stock
determined in accordance  with Section 3.1 and a payment in cash with respect to
fractional  shares,  if any,  determined  in  accordance  with Section 3.2. Each
certificate  representing Buyer Common Stock will bear a notation  incorporating
the Rights  Agreement (as that term is defined in Section 2.1(f) of the Plan) by
reference and certificates representing the Buyer Common Stock will evidence and
entitle the holders thereof to certain rights as set forth in and subject to the
terms of the  Rights  Agreement  ("Rights").  Certificates  issued for the Buyer
common Stock shall be deemed to be certificates for said Rights.

         (b) No dividends or other  distributions of any kind which are declared
payable to  shareholders of record of the Buyer Common Stock after the Effective
Date will be paid to persons  entitled to receive  such  certificates  for Buyer
Common Stock until such persons surrender their certificates representing Seller
Shares.  Upon surrender of such  certificates  representing  Seller Shares,  the
holder  thereof  shall  be  paid,  without  interest,  any  dividends  or  other
distributions with respect to the Buyer Common Stock as to which the record date
and payment date  occurred on or after the  Effective  Date and on or before the
date of surrender.

         (c) If any  certificate  for a Buyer  Share is to be  issued  in a name
other  than that in which the  certificate  for a Seller  Share  surrendered  in
exchange  therefor is registered,  it shall be a condition of such exchange that
the person requesting such exchange shall pay to the Exchange Agent any transfer
costs,   taxes  or  other  expenses  required  by  reason  of  the  issuance  of
certificates for such Buyer Share in a name other than the registered  holder of
the certificate surrendered, or such persons shall establish to the satisfaction
of Buyer and the Exchange  Agent that such costs,  taxes or other  expenses have
been paid or are not applicable.

         (d) All dividends or distributions, and any cash to be paid pursuant to
Section 3.2 in lieu of  fractional  shares,  if held by the  Exchange  Agent for
payment or delivery to the holders of  unsurrendered  certificates  representing
Seller  Shares and  unclaimed  at the end of one year from the  Effective  Date,
shall  (together  with any  interest  earned  thereon)  at such  time be paid or
redelivered by the Exchange Agent to Buyer,  and after such time any holder of a
certificate representing a Seller Share who has not surrendered such certificate
to the  Exchange  Agent  shall,  subject to  applicable  law,  look as a general
creditor   only  to  Buyer  for  payment  or  delivery  of  such   dividends  or
distributions  or cash,  as the case may be.  Buyer  shall  not be liable to any
holder  of a share of  Seller  Common  Stock for such  share  (or  dividends  or
distributions  with respect thereto)  delivered to a public official pursuant to
any applicable abandoned property, escheat or similar law.

         (e) Upon the Effective  Date,  the stock transfer books of Seller shall
be closed and no transfer of Seller  Common  Stock shall  thereafter  be made or
recognized.

         (f) In the  event  that  prior to the  Effective  Date the  outstanding
shares of Buyer Common Stock or Seller  Common Stock shall have been  increased,
decreased or changed into or exchanged for a different  number or kind of shares
or securities by recapitalization, reclassification, stock dividend, stock split
or other like changes in Buyer's or Seller's  capitalization,  or a distribution
shall be made on Buyer  Common  Stock or  Seller  Common  Stock in any  security
convertible  into  Buyer  Common  Stock or  Seller  Common  Stock,  respectively
(provided  that no such action shall be taken by Seller  without  Buyer's  prior
written consent pursuant to Section 3.2(e) of the Plan), then an appropriate and
proportionate adjustment shall be made in the number and kind of shares of Buyer
Common Stock to be thereafter delivered pursuant to this Merger Agreement.

         3.4 All shares of Buyer  Common  Stock  shall  remain  outstanding  and

                                    EXHIBIT C
























<PAGE>








                             STOCK OPTION AGREEMENT

         This  AGREEMENT is dated as of November 13,  1997,  between  SierraWest
Bancorp ("Sierra"), a California corporation, and California Community
Bancshares, a California corporation ("CCBC").

                                W I T N E S S E T H:

         WHEREAS,  the Boards of Directors  of Sierra and CCBC have  approved an
Plan of  Acquisition  and  Merger  ("Plan")  dated as of the date  hereof  which
contemplates  the  acquisition  by Sierra of CCBC by means of the merger of CCBC
with and into Sierra, with Sierra as the entity surviving the merger;

         WHEREAS,  as a condition to Sierra's  entry into the Plan and to induce
such  entry,  CCBC has agreed to grant to Sierra the option set forth  herein to
purchase shares of CCBC's  authorized but unissued common stock,  par value $.10
per share ("Common Stock");

         Unless otherwise  provided in this Agreement,  capitalized  terms shall
have the meanings ascribed to such terms in the Plan.

         NOW, THEREFORE, in consideration of the premises herein contained,  the
parties agree as follows:

         1.  Grant of  Option.  Subject  to the terms and  conditions  set forth
herein,  CCBC hereby grants to Sierra an option (the "Option") to purchase up to
282,914 shares of Common Stock (the "Option Shares"), at a per share price equal
to the  average  of the bid and ask prices  for CCBC  Common  Stock for the five
trading  days  preceding  the  execution  of the Plan  (the  "Exercise  Price");
provided,  however,  that in the event CCBC issues or agrees to issue any shares
of Common  Stock to an  Acquiring  Person  (as that term is defined in Section 6
herein) at a price less than the Exercise  Price,  the  Exercise  Price shall be
equal to such lesser price.

         2.   Exercise of Option.

                  (a) Sierra may  exercise the Option,  in whole or in part,  in
accordance  with and to the extent  permitted by  applicable  law at any time or
from time to time but only upon or after the  occurrence of a Purchase Event (as
that term is defined in Paragraph (b) below of this  section);  provided that to
the extent the Option shall not have been  exercised,  it shall terminate and be
of no further force and effect upon the earliest to occur (such  earliest  date,
the  "Expiration  Date") of (i) the  termination of the Plan pursuant to Section
11.2 (a) and (g) thereof;  (ii) the date of termination pursuant to Section 11.2
(b),  (c),  (d),  (e) or (h) thereof if such date is prior to a Purchase  Event;
(iii) the effective time of the  acquisition  of CCBC by Sierra  pursuant to the
Plan, or (iv) twelve months following the occurrence of the earliest to occur of
(A) the date-of any  termination  of the Plan other than as  described in (i) or
(ii)  above  or  (B)  the  date  of  first   occurrence  of  a  Purchase  Event.
Notwithstanding  the foregoing,  CCBC shall not be obligated to issue the Option
Shares  upon  exercise  of  the  Option  (i)  in the  absence  of  any  required
governmental  or regulatory  waiver,  consent or approval  necessary for CCBC to
issue such Option Shares or for Sierra or any  transferee to exercise the Option
or prior to the expiration or termination of any waiting period required by law,
or (ii) so long as any injunction or other order, decree or ruling issued by any
federal or state court of competent  jurisdiction  is in effect which  prohibits
the sale or delivery of the Option Shares.

                  (b) As used herein,  a "Purchase  Event"  shall have  occurred
when: (i) CCBC or any subsidiary of CCBC,  (without the prior written consent of
Sierra)  enters into an agreement  with any person  (other than Sierra or any of
its subsidiaries)  pursuant to which such person would: (x) merge or consolidate
with, or enter into any similar transaction with CCBC or any subsidiary of CCBC,
(y) purchase,  lease or otherwise acquire all or substantially all of the assets
of CCBC or (z) purchase or otherwise  acquire (by merger,  consolidation,  share
exchange or any similar transaction)  securities representing 10 percent or more
of the voting shares of CCBC (the transactions  referred to in subparagraph (x),
(y) and (z) are referred to as an "Acquisition Transaction"); (ii) any person or
group  of  persons   acting  in  concert  (other  than  Sierra  or  any  of  its
subsidiaries)  acquires  the  beneficial  ownership  or  the  right  to  acquire
beneficial  ownership of  securities  representing  24.99 percent or more of the
voting  shares of CCBC (the term  "beneficial  ownership"  for  purposes of this
Agreement  shall have the meaning set forth in Section  13(d) of the  Securities
Exchange  Act of 1934,  as amended (the  "Exchange  Act"),  and the  regulations
promulgated  thereunder);  (iii) the  shareholders  of CCBC fail to approve  the
business  combination  between CCBC and Sierra  contemplated  by the Plan at any
meeting  of such  shareholders  which  has been  held for  that  purpose  or any
adjournment or postponement  thereof,  the failure of such a shareholder meeting
to occur prior to termination of the Plan, or the withdrawal or modification (in
a manner adverse to Sierra) of the  recommendation  of CCBC's Board of Directors
of the Merger and Plan that the  shareholders of CCBC approve the Merger and the
Plan, in each case, after there shall have been a public  announcement  that any
person (other than Sierra or any of its  subsidiaries),  shall have (A) made, or
publicly  disclosed an intention to make, a proposal to engage in an Acquisition
Transaction,  (B)  commenced  a tender  offer,  as  defined  herein,  or filed a
registration  statement  under  the  Securities  Act of 1933,  as  amended  (the
"Securities  Act"), with respect to an exchange offer, as defined herein, or (C)
filed an application  (or given a notice),  whether in draft or final form, with
the  Department  of Financial  Institutions  of the State of California or other
federal or state bank regulatory authority, which application or notice has been
accepted for processing,  for approval to engage in an Acquisition  Transaction;
(iv)  any  person  (other  than  Sierra  or  other  than  in  connection  with a
transaction which Sierra has given its prior written consent),  shall have filed
an application or notice with the  Department of Financial  Institutions  of the
State of California or other federal or state bank regulatory  authority,  which
application or notice has been accepted for  processing,  for approval to engage
in an Acquisition  Transaction,  exchange offer or tender offer;  (v) CCBC shall
have  willfully  breached  any covenant or  obligation  contained in the Plan in
anticipation of engaging in a Purchase  Event,  and following such breach Sierra
would be entitled to terminate the Plan (whether immediately or after the giving
of notice or passage of time or both); or (vi) a public  announcement by CCBC of
the  authorization,  recommendation  or  endorsement  by CCBC of an  Acquisition
Transaction,  exchange offer or tender offer or a public announcement by CCBC of
an intention to  authorize,  recommend or announce an  Acquisition  Transaction,
exchange  offer or tender offer.  If a Purchase  Event has occurred,  the Option
shall  continue to be  exercisable  until its  termination  in  accordance  with
Section 2(a) hereof.  CCBC shall notify Sierra promptly in writing upon learning
of the occurrence of a Purchase  Event,  it being  understood that the giving of
such notice by CCBC shall not be a condition  to the right of Sierra to transfer
or exercise the Option. As used in this Agreement,  "person" shall have the same
meaning  set  forth in the Plan.  As used in this  paragraph  "tender  offer" or
"exchange  offer" shall mean,  respectively,  the  commencement (as such term is
defined in Rule 14d-2  promulgated  under the Exchange Act) by any person (other
than Sierra or any  subsidiary of Sierra) of, or the filing by any person (other
than Sierra or any subsidiary of Sierra) of a registration  statement  under the
Securities Act with respect to, a tender offer or exchange offer,  respectively,
to purchase  shares of CCBC Stock such that,  upon  consummation  of such offer,
such  person  would own or control  10  percent or more of the  then-outstanding
shares of CCBC Stock.

                  (c) In the event a Purchase Event occurs,  Sierra may elect to
exercise the Option.  If Sierra wishes to exercise the Option,  it shall send to
CCBC a written  notice  (the date of which  shall be  referred  to herein as the
"Notice  Date")  which  specifies  (i) the total  number of Option  Shares to be
purchased,  and (ii) a place and date not  earlier  than two  business  days nor
later  than  ten  business  days  from the  Notice  Date  for the  closing  (the
"Closing")  of such purchase (the "Closing  Date");  provided  however,  that if
prior notification to or approval of the Department of Financial Institutions of
the State of California or any other regulatory agency is required in connection
with such  purchase,  the Holder,  as defined  below,  shall  promptly  file the
required notice or application for approval,  shall promptly notify CCBC of such
filing,  and shall  expeditiously  process  the same and the period of time that
otherwise would run pursuant to this sentence shall run instead from the date on
which any required  notification periods have expired or been terminated or such
approvals  have been obtained and any requisite  waiting period or periods shall
have  passed.  Any exercise of the Option shall be deemed to occur on the Notice
Date relating thereto, subject to receipt of any required regulatory approvals.

         3. Payment and Delivery of Certificates; Sierra Representation.

                  (a) If  Sierra  elects to  exercise  the  Option,  then at the
Closing,  Sierra shall pay to CCBC the aggregate  purchase  price for the Option
Shares purchased pursuant to the exercise of the Option in immediately available
funds by a wire transfer to a bank designated by CCBC.

                  (b) At such Closing,  simultaneously  with the delivery of the
purchase  price for the Option Shares as provided in Paragraph (a) hereof,  CCBC
shall deliver to Sierra a certificate or certificates, registered in the name of
Sierra or its designee,  representing  the number of Option Shares  purchased by
Sierra.  Such  certificates may be endorsed with any legend required pursuant to
any permit or exemption  granted by the Department of Financial  Institutions of
the State of California or any other regulatory agency, as well as the following
legend:

                  THE TRANSFER OF THE SHARES  REPRESENTED BY THIS CERTIFICATE IS
SUBJECT TO CERTAIN  PROVISIONS  OF AN AGREEMENT  BETWEEN THE  REGISTERED  HOLDER
HEREOF AND THE ISSUER,  A COPY OF WHICH  AGREEMENT  IS ON FILE AT THE  PRINCIPAL
OFFICE OF THE ISSUER.  A COPY OF SUCH  AGREEMENT  WILL BE PROVIDED TO THE HOLDER
HEREOF WITHOUT CHARGE UPON RECEIPT BY THE ISSUER OF A REQUEST THEREFOR.

Any such legend shall be removed by delivery of a substitute certificate without
such legend if Sierra  shall have  delivered  to CCBC an opinion of counsel,  in
form and substance  satisfactory  to CCBC,  that such legend is not required for
purposes of assuring compliance with applicable  securities or other law or with
this Agreement.

                  (c)  Except  as  otherwise  provided  herein,   Sierra  hereby
represents and warrants to CCBC that the Option is being,  and any Option Shares
issued  upon  exercise  of the Option  will be,  acquired  by Sierra for its own
account  and not with a view to any  distribution  thereof,  and Sierra will not
sell any Option  Shares  purchased  pursuant to exercise of the Option except in
compliance with applicable securities and other laws.

         4.  Representations.  CCBC hereby  represents and warrants to Sierra as
follows:

                  (a) CCBC has all  requisite  corporate  power and authority to
enter  into  and  perform  all of its  obligations  under  this  Agreement.  The
execution,   delivery  and   performance  of  this  Agreement  and  all  of  the
transactions  contemplated  hereby have been duly  authorized  by all  necessary
corporate  action on the part of CCBC. This Agreement has been duly executed and
delivered  by CCBC  and  constitutes  a valid  and  binding  agreement  of CCBC,
enforceable   against  CCBC  in  accordance  with  its  terms,   except  as  the
enforceability  hereof may be limited by bankruptcy,  insolvency,  moratorium or
other similar laws  affecting the rights of creditors  generally or by equitable
principles, whether such enforcement is sought in law or equity.

                  (b) The execution  and delivery by CCBC of this  Agreement and
the  consummation of the  transactions  herein  contemplated do not and will not
violate or conflict with CCBC's  Certificate  of  Incorporation  or Bylaws,  any
statute,  regulation,  judgment, order, writ, decree or injunction applicable to
CCBC (other than as may be effected by Sierra's  ownership  of CCBC Common Stock
exceeding  certain  limits set forth by statute or regulation) or its properties
or assets and do not and will not violate, conflict with, result in a breach of,
constitute  a default  (or an event which with due notice  and/or  lapse of time
would  constitute a default) under,  result in a termination of,  accelerate the
performance required by, or result in the creation of any lien, pledge, security
interest,  charge or other  encumbrance  upon any of the properties or assets of
CCBC under the terms,  conditions  or provisions  of any note,  bond,  mortgage,
indenture,  deed of trust, or loan agreement or other  agreement,  instrument or
obligation to which CCBC is a party,  or by which CCBC or any Of its  properties
or assets may be bound or affected.

                  (c) CCBC has taken all necessary corporate action to authorize
and  reserve  and to permit it to issue,  and at all times from the date  hereof
through the  termination  of this Agreement in accordance  with its terms,  will
have reserved for issuance upon the exercise of the Option a number of shares of
Common Stock  sufficient  to satisfy the exercise of the Option in full,  all of
which Common Stock,  upon issuance  pursuant  hereto,  shall be duly authorized,
validly issued,  fully paid and  nonassessable,  and shall be delivered free and
clear of all claims,  liens,  encumbrances,  security  interests and  preemptive
rights.

         5.   Adjustment Upon Changes in Capitalization.

                  (a) In the event of any stock dividend, stock split, split-up,
recapitalization,  reclassification,  combination, exchange of shares or similar
transaction or event with respect to Common Stock, the type and number of shares
or securities  subject to the Option and the Exercise Price  therefor,  shall be
adjusted  appropriately,  and proper  provision  shall be made in the agreements
governing such  transaction  so that Sierra shall receive,  upon exercise of the
Option,  the number and class of shares or other  securities  or  property  that
Sierra  would have  received  in respect of Common  Stock if the Option had been
exercised  immediately  prior to such  event,  or the record  date  thereof,  as
applicable.  If any  shares of Common  Stock are  issued  after the date of this
Agreement  (other than pursuant to an event  described in the first  sentence of
this Section  5(a)),  the number of shares of Common Stock subject to the Option
shall be adjusted so that, after such issuance,  it, together with any shares of
Common Stock previously issued to Sierra pursuant hereto, equals 19.9 percent of
the number of shares of Common Stock then issued and outstanding, without giving
effect to any shares subject to or issued pursuant to this Option.

                  (b) In the event that  CCBC,  shall,  prior to the  Expiration
Date, enter into an agreement: (i) to consolidate with or merge into any person,
other than Sierra or one of its subsidiaries, and shall not be the continuing or
surviving  corporation  of such  consolidation  or  merger,  (ii) to permit  any
person,  other than  Sierra or one of its  subsidiaries,  to merge into CCBC and
CCBC shall be the continuing or surviving  corporation,  but, in connection with
such merger,  the then outstanding  shares of Common Stock shall be changed into
or exchanged  for stock or other  securities of CCBC or any other person or cash
or any other  property or the  outstanding  shares of Common  Stock  immediately
prior to such merger shall after such merger  represent  less than 50 percent of
the outstanding shares and share equivalents of the merged company;  or (iii) to
sell or otherwise transfer all or substantially all of its assets to any person,
other than Sierra or one of its  subsidiaries,  then, and in each such case, the
agreement  governing such transaction  shall make proper  provisions so that the
Option shall,  upon the  consummation of any such transaction and upon the terms
and conditions set forth herein,  be converted into, or exchanged for, an option
(the  "Substitute  Option"),  at the  election  of  Sierra,  of  either  (x) the
Succeeding  Corporation  (as defined  below),  (y) any person that  controls the
Succeeding Corporation, or (z) in the case of a merger described in clause (ii),
CCBC (in each case,  such person  being  referred to as the  "Substitute  Option
Issuer.")

                  (c) The  Substitute  Option  shall  have the same terms as the
Option,  provided, that, if the terms of the Substitute Option cannot, for legal
reasons,  be the same as the Option,  such terms shall be as similar as possible
and in no event less advantageous to Sierra.  The Substitute Option Issuer shall
also enter into an agreement  with the  then-holder or holders of the Substitute
Option in substantially the form as this Agreement, which shall be applicable to
the Substitute Option.

                  (d) The Substitute Option shall be exercisable for such number
of shares of the Substitute Common Stock (as hereinafter defined) as is equal to
the Assigned Value (as hereinafter  defined)  multiplied by the number of shares
of Common Stock for which the Option was theretofore exercisable, divided by the
Average Price (as  hereinafter  defined).  The exercise  price of the Substitute
Option per share of the Substitute Common Stock (the "Substitute  Option Price")
shall then be equal to the Exercise Price  multiplied by a fraction in which the
numerator  is the number of shares of the Common  Stock for which the Option was
theretofore  exercisable  and the  denominator is the number of shares for which
the Substitute Option is exercisable.

                  (e) The following terms have the meanings indicated:

                  (i) "Succeeding  Corporation" shall mean (x) the continuing or
surviving  corporation  of a  consolidation  or merger  with CCBC (if other than
CCBC), (y) CCBC in a merger in which CCBC is the continuing or surviving person,
and (z) the  transferee  of all or any  substantial  part of CCBC assets (or the
assets of its subsidiaries).

                  (ii)"Substitute  Common  Stock"  shall mean the  common  stock
issued by the Substitute Option Issuer upon exercise of the Substitute Option.

                  (iii) "Assigned Value" shall mean the highest of (x) the price
per share of Common Stock at which a tender offer or exchange offer therefor has
been made by any person  (other than Sierra or its  subsidiaries)  (y) the price
per share of Common Stock to be paid by any person  (other than Sierra or any of
its  subsidiaries)  pursuant  to an  agreement  with CCBC,  and (z) the  highest
closing  sales price per share of Common Stock as quoted on the Nasdaq  National
Market  (or if Common  Stock is not quoted on the Nasdaq  National  Market,  the
highest bid price per share on any day as quoted on the principal trading market
or  securities  exchange  on which  such  shares  are  traded as  reported  by a
recognized  source  chosen by Sierra)  within the six-month  period  immediately
preceding the  agreement  referred to in (y);  provided,  that in the event of a
sale of less than all of CCBC's  assets,  the Assigned Value shall be the sum of
the price paid in such sale for such assets and the current  market value of the
remaining  assets of CCBC as  determined by a nationally  recognized  investment
banking firm selected by Sierra and  reasonably  acceptable to CCBC,  divided by
the number of shares of Common Stock  outstanding  at the time of such sale.  In
the event that an exchange  offer is made for Common  Stock or an  agreement  is
entered into for a merger or consolidation  involving  consideration  other than
cash, the value of the  securities or other property  issuable or deliverable in
exchange for the Common  Stock shall be  determined  by a nationally  recognized
investment  banking firm mutually selected by Sierra and CCBC (or if applicable,
the Succeeding Corporation),  provided that if a mutual selection cannot be made
as to such investment banking firm, it shall be selected by Sierra.

                  (iv)"Average  Price" shall mean the average closing price of a
share of the Substitute Common Stock for the one year immediately  preceding the
consolidation,  merger  or sale in  question,  but in no event  higher  than the
closing price of the shares of the Substitute  Common Stock on the day preceding
such  consolidation,  merger or sale, provided that if CCBC is the issuer of the
Substitute  Option,  the Average Price shall be computed with respect to a share
of common stock issued by CCBC,  the person  merging into CCBC or by any company
which controls or is controlled by such merging person, as Sierra may elect.

                  (f) In no event pursuant to any of foregoing  paragraphs shall
the Substitute Option be exercisable for more than 19.9 percent of the aggregate
of the shares of the Substitute  Common Stock  outstanding  immediately prior to
exercise of the Substitute Option. In the event that the Substitute Option would
be  exercisable  for more than 19.9  percent of the  aggregate  of the shares of
Substitute  Common Stock but for this clause (f), the  Substitute  Option Issuer
shall make a cash  payment to Sierra equal to the excess of (i) the value of the
Substitute  Option  without  giving effect to the  limitation in this clause (f)
over  (ii)  the  value of the  Substitute  Option  after  giving  effect  to the
limitation in this clause (f). This difference in value shall be determined by a
nationally  recognized  investment  banking  firm  selected  by  Sierra  and the
Substitute Option Issuer.

                  (g) CCBC shall not enter  into any  transaction  described  in
subsection  (b) of this  Section 5 unless  the  Succeeding  Corporation  and any
person  that  controls  the  Succeeding  Corporation  assume in writing  all the
obligations  of CCBC  hereunder and take all other actions that may be necessary
so that the  provisions  of this  Agreement,  including  but not limited to this
Section 5, are given full force and effect (including,  without limitation,  any
action that may be necessary so that the shares of  Substitute  Common Stock are
in no way  distinguishable  from or have lesser economic value than other shares
of common stock issued by the Substitute Option Issuer).

         6. Purchase of Option Shares and Options by CCBC.

                  (a) From and after the first date a  transaction  specified in
Section 5(b) herein is  consummated  (the  "Repurchase  Event"),  and subject to
applicable regulatory  restrictions,  Sierra or a holder or former holder of any
Options (a  "Holder")  who has  exercised  the Options in whole or in part shall
have the right to require CCBC to purchase some or all of the Option Shares at a
purchase price per share (the "Purchase  Price") equal to the highest of (i) 100
percent of the Exercise Price,  (ii) the highest price paid or agreed to be paid
for shares of Common Stock by an Acquiring  Person (as defined in Paragraph  (b)
of this Section) in any tender offer,  exchange  offer or other  transaction  or
series of related  transactions  involving the acquisition of 10 percent or more
of the outstanding shares of Common Stock during the one-year period immediately
preceding  the Purchase  Date (as defined in Paragraph  (d) of this Section) and
(iii) in the event of a sale of all or substantially  all of CCBC's assets,  (x)
the sum of the price paid in such sale for such  assets and the  current  market
value of the remaining  assets of CCBC as determined by a recognized  investment
banking  firm  jointly  selected  by such  Holder and CCBC,  each acting in good
faith,  divided  by (y) the number of shares of Common  Stock then  outstanding;
provided, however, that the amount calculated pursuant to clauses (ii) and (iii)
of this Section 6(a) shall not exceed $2.0 million. In the event that any of the
consideration paid or agreed to be paid by an Acquiring Person for any shares of
Common  Stock  or for any of  CCBC's  assets  consists  in  whole  or in part of
securities,  the  value of such  securities  for  purposes  of  determining  the
Purchase  Price shall be determined  (i) if there is an existing  public trading
market therefor,  by the average of the last sales prices for such securities on
the ten trading  days  ending  three  trading  days prior to the payment of such
consideration  (if such  consideration  has  been  paid) or prior to the date of
determination (if such consideration has not yet been paid) and (ii) if there is
no  existing  public  trading  market  for  such  securities,  by  a  recognized
investment  banking firm jointly selected by the Holder and CCBC, each acting in
good faith.  The Holder's  right to require CCBC to purchase  some or all of the
Option  Shares  under  this  Section  shall  expire on the day which is one year
following the  Repurchase  Event;  provided,  that if CCBC is  prohibited  under
applicable  regulations  from  purchasing  Common Stock as to which a Holder has
given notice hereunder, then the Holder's right to require CCBC to purchase such
shares  shall expire on the date which is one year  following  the date on which
CCBC no longer is prohibited from purchasing such shares: provided further, that
CCBC shall use its best  efforts to obtain any consent or approval  and make any
filing  required for CCBC to  consummate  as quickly as possible the purchase of
the Common Stock contemplated hereunder.

                  (b) For purposes of this Agreement,  "Acquiring  Person" shall
mean a person or group (as such terms are  defined in the  Exchange  Act and the
rules and  regulations  thereunder)  other than Sierra or a subsidiary of Sierra
who on or after the date of this Agreement  engages in a transaction which gives
rise to a Purchase Event.

                  (c) Subject to applicable  regulatory  restrictions,  from and
after a  Repurchase  Event or after  Sierra  receives  official  notice  that an
approval of the Department of Financial Institutions of the State of California,
or any other regulatory  authority,  required for the exercise of the Option and
purchase of the Option Shares will not be issued or granted, a Holder shall have
the right to require  CCBC to purchase  some or all of the Options  held by such
Holder at a price equal to the Purchase  Price minus the  Exercise  Price on the
Purchase Date (as defined in Paragraph  (d) of this  Section)  multiplied by the
number of shares of Common Stock that may be purchased on the Purchase Date upon
the exercise of the Options elected to be purchased; provided, however, that the
amount  calculated  pursuant to this Section 6(c) shall not exceed $2.0 million.
Notwithstanding  the  termination  date of the Options,  the  Holder's  right to
require CCBC to purchase  some or all of the Options  under this  Section  shall
expire on the day which is one year  following the Repurchase  Event;  provided,
that if CCBC is prohibited  under  applicable  regulations  from  purchasing the
Options  as to which an Holder has given  notice  hereunder,  then the  Holder's
right to require CCBC to purchase  such Options shall expire on the day which is
one  year  following  the  date on  which  CCBC no  longer  is  prohibited  from
purchasing such Options;  provided further, that CCBC shall use its best efforts
to obtain any  consent or  approval  and make any  filing  required  for CCBC to
consummate  as quickly as possible  the  purchase  of the  Options  contemplated
hereunder.

                  (d) A  Holder  may  exercise  its  right  to  require  CCBC to
purchase the Common Stock or Options  (collectively,  "Securities")  pursuant to
this Section by surrendering  for such purpose to CCBC, at its principal  office
or at such other office or agency  maintained by CCBC for that  purpose,  within
the period specified above, the certificates or other  instruments  representing
the  Securities to be purchased  accompanied by a written notice stating that it
elects to require CCBC to purchase all or a specified number of such Securities.
Within  five  business  days  after  the  surrender  of  such   certificates  or
instruments and the receipt of such notice relating thereto, to the extent it is
legally  permitted to do so, CCBC shall  deliver or cause to be delivered to the
Securities  Holder  (i) a bank  cashier's  or  certified  check  payable  to the
Securities Holder in an amount equal to the applicable  purchase price therefor,
and (ii) if less than the full number of Securities evidenced by the surrendered
instruments are being purchased, a new certificate or instrument, for the number
of Securities  evidenced by such surrendered  certificates or other  instruments
less the number of Securities purchased.  Such purchases shall be deemed to have
been made at the close of  business  on the date  (the  "Purchase  Date") of the
receipt  of such  notice  and of such  surrender  of the  certificates  or other
instruments  representing  the  Securities to be purchased and the rights of the
Securities Holder, except for the right to receive the applicable purchase price
therefor in accordance herewith, shall cease on the Purchase Date.

         7. Demand Registration Rights. As promptly as practicable upon Sierra's
request  after a Purchase  Event,  CCBC agrees to prepare and file not more than
two registration  statements,  prospectuses or permit or exemption  applications
("Registration  Event") as appropriate,  under federal and any applicable  state
securities  laws, with respect to any proposed sale of any warrants,  options or
other  securities  representing  any of Sierra's  rights under this Agreement or
proposed  dispositions  by Sierra of any or all of the  Option  Shares,  if such
registrations or filings are required by law or regulation,  and to use its best
efforts to cause any such  registration  statements  or  prospectuses  to become
effective,  or to have any permit or  exemption  granted,  as  expeditiously  as
possible  and  to  keep  such  registration  statement,  prospectus,  permit  or
exemption  effective  for a period  of not less  than  180 days  unless,  in the
written opinion of counsel to CCBC, addressed to Sierra and satisfactory in form
and  substance  to  Sierra  and  its  counsel,  registration  (or  filing  of  a
prospectus, or grant of a permit or exemption) is not required for such proposed
transactions.  All fees,  expenses and charges of any kind or nature  whatsoever
incurred in  connection  with any  registration  of, or the  preparation  of any
registration  statement,  prospectus or permit or exemption application relating
to, the Options or the Option  Shares  pursuant to this Section 7 shall be borne
and paid by CCBC;  provided,  however,  that in no event shall this Section 7 be
construed to require CCBC to bear the expense of any change of control notice or
similar  regulatory  filing made by any  purchaser or acquiror of Option  Shares
issued to Sierra pursuant to this Agreement.  In the event Sierra  exercises its
registration  rights  under  this  Section  7, CCBC shall  provide  Sierra,  its
affiliates, each of their respective officers and directors and any underwriters
used by Sierra, with indemnifications,  representations and warranties and shall
cause  its  attorneys  and  accountants  to  deliver  to  Sierra  and  any  such
underwriters   attorneys'  opinions  and  "comfort  letters",   all  of  a  type
customarily  provided  or  delivered  in  connection  with  public  underwritten
offerings  of  securities.  In the event CCBC effects a  registration  of Common
Stock for its own account or for any other  shareholder  of CCBC, it shall allow
Sierra to participate in such registration.  Notwithstanding the foregoing, CCBC
shall  have the right to delay (a  "Delay  Right")  a  Registration  Event for a
period of up to thirty (30) days, in the event it receives a request from Sierra
to  effect  a  Registration  Event,  if  CCBC  (i)  is  involved  in a  material
transaction,  or (ii)  determines,  in the good faith exercise of its reasonable
business judgment, that such registration and offering could adversely effect or
interfere  with  bona fide  material  financing  plans of CCBC or would  require
disclosure of information,  the premature  disclosure of which could  materially
adversely affect CCBC or any transaction under active consideration by CCBC. For
purposes  of this  Agreement,  the  term  "material  transaction"  shall  mean a
transaction which, if CCBC were subject to the reporting  requirements under the
Exchange Act,  would require CCBC to file a current  report on Form 8-K with the
Securities Exchange Commission.  CCBC shall have the right to exercise two Delay
Rights in any eighteen (18) month period.

         8.   Listing.

         If Common Stock or any other securities to be acquired upon exercise of
the Option are then authorized for quotation or trading or listing on the Nasdaq
National Market or any other securities  exchange or automated quotation system,
CCBC,  or any successor  thereto,  upon the request of the holder of the Option,
will  promptly  file an  application,  if required,  to authorize for listing or
trading  or  quotation  the  shares of Common  Stock or other  securities  to be
acquired upon exercise of the Option on the Nasdaq  National Market or any other
securities  exchange or automated quotation system and will use its best efforts
to obtain  approval,  if  required,  of such  listing  or  quotation  as soon as
possible.

         9.   Total Profit.

         Notwithstanding  any other provision of this Agreement to the contrary,
in no event shall Sierra  purchase under the terms of this Agreement that number
of Option Shares which have a Spread Value,  as defined below, in excess of $2.0
million.  In the event the Spread  Value  exceeds  $2.0  million,  the number of
Option  Shares which Sierra is entitled to purchase at the Closing Date shall be
reduced  to the  extent  required  such that the  Spread  Value  following  such
reduction is equal to or less than $2.0 million.  "Spread  Value" shall mean the
difference  between (i) the product of (1) the sum of the total number of Option
Shares  Sierra (x) intends to purchase at a Closing  pursuant to the exercise of
the Option and (y)  previously  purchased  pursuant to the prior exercise of the
Option,  and (2) the closing  price of CCBC Common Stock as quoted on the Nasdaq
National Market on the last trading day immediately  preceding the Closing Date,
and (ii) the product of (1) the total number of Option Shares Sierra (x) intends
to purchase at the Closing  Date  pursuant to the exercise of the Option and (y)
previously  purchased  pursuant to the prior  exercise of the Option and (2) the
applicable Option Price of such Option Shares.

         10.  Miscellaneous.

         (a) Expenses.  Each of the parties  hereto shall bear and pay all costs
and expenses incurred by it or on its behalf in connection with the transactions
contemplated  hereunder,  including  fees  and  expenses  of its  own  financial
consultants, investment bankers, accountants and counsel.

         (b) Entire Agreement.  Except as otherwise  expressly  provided herein,
this Agreement contains the entire agreement between the parties with respect to
the transactions contemplated hereunder and supersedes all prior arrangements or
understandings  with respect thereto,  written or oral. The terms and conditions
of this Agreement  shall inure to the benefit of and be binding upon the parties
hereto and their respective  successors and assigns.  Nothing in this Agreement,
expressed  or implied,  is  intended  to confer  upon any party,  other than the
parties  hereto,  and their  respective  successors  and  assigns,  any  rights,
remedies,  obligations  or  liabilities  under or by reason  of this  Agreement,
except as expressly provided herein.

         (c) Assignment.  At any time after a Purchase Event occurs,  Sierra may
sell,  assign or otherwise  transfer its rights and  obligations  hereunder,  in
whole or in part,  by issuing  Options or  otherwise,  to any person or group of
persons,  subject to applicable law, rule or regulation.  In order to effectuate
the  foregoing,  Sierra (or any direct or  indirect  assignee or  transferee  of
Sierra)  shall be entitled to surrender  this  Agreement to CCBC in exchange for
two or  more  Agreements  entitling  the  holders  thereof  to  purchase  in the
aggregate  the same  number  of shares  of  Common  Stock as may be  purchasable
hereunder.

         (d) Notices.  All notices or other communications which are required or
permitted  hereunder shall be in writing and sufficient if delivered  personally
or by confirmed  facsimile  transmission or sent by registered or certified mail

not performed in accordance with its terms or conditions or otherwise  breached.
It is accordingly  agreed that the parties shall be entitled to an injunction or

__________, 1997

SierraWest Bancorp

P.O. Box 61000
Truckee, CA 96160

                 SierraWest Bancorp-California Community Bancshares Corporation

Ladies and Gentlemen:

         We  have  acted  as  counsel  for   California   Community   Bancshares
Corporation  ("Bancshares"),   a  Delaware  corporation,  and  its  wholly-owned
subsidiary,  Continental Pacific Bank ("CPB"), a California banking corporation,
with respect to the merger (the "Merger") of Bancshares  and SierraWest  Bancorp
("Bancorp"), a California corporation, and with respect to the merger (the "Bank
Merger") of CPB and Bancorp's  wholly-owned  subsidiary SierraWest Bank ("Sierra
Bank"), a California  banking  corporation,  pursuant to the Plan of Acquisition
and Merger dated as of November __, 1997 (the "Agreement")  between  Bancshares,
CPB, Bancorp and Sierra Bank, and Exhibit A (the "Merger Agreement") and Exhibit
B (the  "Bank  Merger  Agreement")  thereto.  This  opinion is  rendered  to you
pursuant to Section 7.6 of the Agreement.  Unless otherwise defined herein,  all
capitalized  terms in this opinion  shall have the meanings  assigned to them in
the Agreement.

         In rendering the opinions hereinafter  expressed,  we have examined and
relied  upon such  documents  and  instruments  as we have  deemed  appropriate,
including the following:

         A.   The Agreement and the exhibits thereto;

         B.  Resolutions  of the boards of directors of Bancshares  and CPB with
respect to the Merger and the Bank Merger;

         C. Certificate of Incorporation of Bancshares certified by the Delaware
Secretary of State as of a recent date;

         D.  Articles  of  Incorporation  of CPB  certified  by  the  California
Secretary of State as of a recent date;

         E.   Bylaws, minute book and stock ledger of Bancshares;

         F.   Bylaws, minute book and stock ledger of CPB;

         G.  Certificate  of  Status  from  the  Delaware   Secretary  of  State
indicating  that  Bancshares is in good standing in Delaware as of a recent date
(the "Bancshares Status Certificate").

         H.  Certificate  of  Status  from  the  California  Secretary  of State
indicating  that CPB is in good  standing in California as of a recent date (the
"CPB Status Certificate");

         I. Registration  Statement on Form S-4 of Bancorp and the related Proxy
Statements  of  Bancshares  and Bancorp  with respect to the Merger and the Bank
Merger (the "Proxy Materials");

         J.   Proceedings of the meeting of shareholders of Bancshares held on
_____________; and,

         K. Officers'  certificates  of Bancshares and CPB as to certain factual
matters.

         We have  obtained,  and have  assumed  and  relied  upon the  accuracy,
genuineness and  completeness  of, such  certificates and assurances from public
officials as we have deemed  necessary or appropriate to enable us to render our
opinion.

         In conducting our examination,  we have assumed, without investigation,
the  genuineness  of  all  signatures  (other  than  that  of  Bancshares),  the
correctness  of all documents  submitted to us as originals,  the  conformity to
original documents of all documents  submitted to us as certified or photostatic
copies and the authenticity of the originals of such copies; the accuracy of the
representations  as to factual  matters  made by Bancorp and  Bancshares  in the
Agreement;  the accuracy of representations and statements as to factual matters
made by officers and  employees of  Bancshares;  that the Agreement is the valid
and binding  obligation of Bancorp and Sierra Bank; that Bancorp and Sierra Bank
will enforce the Agreement in a  commercially  reasonable  manner;  and that the
Agreement contains the entire agreement of the parties.

         Our opinions in paragraphs 4 and 5 below are subject to :

                           (i) the  effect of  bankruptcy,  insolvency,
reorganization,  arrangement,  moratorium, and other similar laws now or here-
after in effect relating to or affecting the rights of creditors generally;

                           (ii)  limitations  imposed by California law, federal
law, or equitable principles upon any of the remedies,  covenants,  or other  
provisions of the Agreement and upon the availability of injunctive  relief or 
other equitable  remedies,  including, without  limitation,  the effect of  
California  and  federal  court  decisions, invoking  statutes  or  principles
of  equity,  which  have held  that  certain covenants and provisions of 
agreements are  unenforceable  where: (A) the breach of such covenants or 
provisions imposes  restrictions or burdens upon one party, and it cannot be  
demonstrated  that the  enforcement  of such  restrictions  or burdens is 
reasonably  necessary for the protection of the other party, or (B) a party's  
enforcement  of such  covenants or provisions  under the  circumstances would 
violate such party's implied covenants of good faith and fair dealing, and

                           (iii)  the power of  federal  and state  courts  to
refuse to  enforce  (or to stay the enforcement  of) any  provision  of the  
Agreement  which  purports to waive the rights of Bancshares to assert the 
claims or defenses available to Bancshares by statute, common law, or equity.

         Whenever a statement herein with respect to the existence or absence of
facts is qualified by the phrases "we are not aware" or "to our  knowledge,"  it
is  intended  to  indicate  that,  during  the course of our  representation  of
Bancshares and CPB, no information  that would give us current actual  knowledge
of the inaccuracy of such statement has come to the attention of those attorneys
in  this  firm  who  have  rendered  legal  services  in  connection   with  the
representation  described in the  introductory  paragraph of this opinion letter
and such statement is based solely upon (i) an inquiry of attorneys  within this
firm who have rendered such services;  (ii) receipt of a certificate executed by
an officer of Bancshares or CPB covering  such  matters;  and (iii)  opinions of
other counsel engaged by Bancshares or CPB regarding any litigation matters with
respect to which we do not  represent  Bancshares or CPB.  However,  we have not
undertaken  any  independent  investigation  to  determine  the accuracy of such
statement,  and any limited  inquiry  undertaken by us during the preparation of
this  opinion  letter  should  not be  regarded  as  such an  investigation;  no
inference as to our knowledge of any matters bearing on the accuracy of any such
statement should be drawn from the fact of our  representation  of Bancshares or
CPB.

         Based upon and subject to the foregoing, we are of the opinion that:

         1.  Bancshares is a Delaware  corporation  duly  incorporated,  validly
existing  and in good  standing  under the laws of the State of Delaware and has
the  corporate  power to own all of its  property and assets and to carry on its
business as it is now being  conducted.  Bancshares is a registered bank holding
company under the Bank Holding Company Act of 1956.

         2. CPB is a California banking  corporation duly incorporated,  validly
existing and in good standing  under the laws of the State of California and has
the  corporate  power to own all of its  property and assets and to carry on its
business as it is now being conducted. CPB is duly licensed as a commercial bank
by the  California  Department of Financial  Institutions,  and its deposits are
insured  by  the  Federal  Deposit  Insurance  Corporation  in  accordance  with
applicable laws and regulations.

         3. Bancshares and CPB have the corporate power and corporate  authority
to enter into and perform their respective obligations under the Agreement,  the
Merger  Agreement and the Bank Merger  Agreement.  The execution and delivery by
Bancshares and CPB of the  Agreement,  the execution by Bancshares of the Merger
Agreement and the execution by CPB of the Bank Merger Agreement did not, and the
consummation  by  Bancshares  and CPB of the  transactions  contemplated  by the
Agreement,  the Merger Agreement and the Bank Merger Agreement will not, violate
any provision of Bancshares' or CPB's  certificate or articles of  incorporation
or bylaws,  any provision of federal or California  law applicable to Bancshares
or CPB, or any  governmental  regulation  applicable  to  Bancshares  or CPB, or
constitute a material  default under, or result in the breach or acceleration of
any obligation or the creation of any material lien under any material agreement
to which Bancshares or CPB is bound and of which we have knowledge  (except that
we  express  no  opinion  relating  to the  effect  of the  Agreement  under any
financial test or ratio contained in any mortgage, lease, agreement, instrument,
judgment,  decree,  order,  arbitration award, writ, or injunction applicable to
Bancshares or CPB).

         4. The Agreement and the Merger  Agreement  have been duly  authorized,
executed and  delivered by  Bancshares,  and each of them is a valid and binding
agreement of Bancshares.

         5.  The  Agreement  and  the  Bank  Merger  Agerement  have  been  duly
authorized,  executed  and  delivered  by CPB,  and each of them is a valid  and
binding agreement of CPB.

         6. All  California  state and  federal  regulatory  approvals  that are
required to be obtained by Bancshares and CPB in connection  with the Merger and
the Bank Merger have been obtained.

         7. To our  knowledge,  neither  Bancshares  nor CPB is a party to,  nor
threatened with, any legal action or other  proceeding or  investigation  before
any court,  any arbitrator of any kind or any government  agency that challenges
or  questions  the  authority  or ability of  Bancshares  or CPB to perform  its
obligations  under  the  Agreement,  the  Merger  Agreement  or the Bank  Merger
Agreement or to carry out the Merger or the Bank Merger,  or where the amount in
controversy  exceeds  $50,000 and which has not been  disclosed by Bancshares to
Bancorp.

         8. The authorized  capital stock of Bancshares  consists of ___________
shares of no par value common  stock.  To our knowledge and before giving effect
to the issuance of shares in connection with the Merger:

              (a) _________ shares of common stock are duly authorized,  validly
issued and outstanding, fully paid and nonassessable;

              (b) there are no  outstanding  (i) options,  agreements,  calls or
commitments  of any character  that would  obligate  Bancshares to issue,  sell,
pledge,  assign or otherwise  encumber or dispose of, or to purchase,  redeem or
otherwise  acquire,  any Bancshares common stock or any other equity security of
Bancshares,  or (ii) warrants or options  relating to, rights to acquire or debt
or equity securities  convertible into, shares of Bancshares common stock or any
other equity security of Bancshares; and.

              (c) the  outstanding  common  stock  of  Bancshares  has not  been
registered  with the Securities and Exchange  Commission or the FDIC pursuant to
the 1934 Act.

         In  connection  with the  preparation  of the  Registration  Statement,
including the related Proxy  Materials,  we have  performed  legal  services for
Bancshares  and  participated  in  conferences  with  directors,   officers  and
employees of Bancshares and  representatives of the independent  accountants for
Bancshares. At such conferences,  the contents of the Proxy Materials related to
Bancshares and related  matters were discussed and,  although we are not passing
upon, and do not assume any  responsibility  for, the accuracy,  completeness or
fairness of the  statements  related to  Bancshares  and  contained in the Proxy
Materials,  on the basis of the  foregoing,  we are not aware of any facts  that
would  lead us to  believe  that the  Proxy  Materials  as of the  date  thereof
contained any statement in respect to Bancshares which, at the time and in light
of the  circumstances  under  which it was made,  was false or  misleading  with
respect to any material fact or omitted to state any material fact  necessary in
order to make the  statements  therein  not false or  misleading.  In making the
foregoing  statement,  we  express  no  belief  with  respect  to the  financial
statements  and other  financial  and  statistical  data  included  in the Proxy
Materials  or with  respect  to  statements  in, or  omissions  from,  the Proxy
Materials made in reliance upon, or in conformity with, information furnished by
Bancshares for use in connection with the Proxy Materials.

         We are  members  of the bar of the State of  California.  Our  opinions
below are limited to the effect of (i) the laws of the State of  California  and
(ii) the federal  laws of the United  States of  America;  we express no opinion
with respect to the laws of any other jurisdiction.

         This  opinion  is  rendered  solely  for  the  benefit  of  Bancorp  in
connection with the Merger and the Bank Merger and may not be relied upon by any
other party or for any other  purpose.  Neither the  original  nor any copies of
this  opinion may be furnished  to any other  person  without our prior  written
consent.

                                                       Very truly yours,



                                                       Lillick & Charles, LLP

SierraWest Bancorp

P.O. Box 61000
Truckee, CA  96160

Ladies and Gentlemen:

     The   undersigned  is  a  director  of  California   Community   Bancshares
Corporation  ("Bancshares")  and an owner of common stock of  Bancshares  ("CCBC
Shares").

     Bancshares  and  its  wholly-owned  subsidiary,  Continental  Pacific  Bank
("CPB"),  have entered into a Plan of Acquisition and Merger ("Agreement") dated
today's  date  with  SierraWest   Bancorp   ("Bancorp")  and  its   wholly-owned
subsidiary, SierraWest Bank ("Sierra Bank"), related to the Merger of Bancshares
into Bancorp and the merger of CPB into Sierra  Bank.  In  consideration  of the
premises and the representations,  warranties, agreements and conditions in this
letter  and in the  Agreement  and in order to induce  Bancorp  to  execute  the
Agreement, the undersigned agrees and undertakes, as follows:

     The  undersigned  will  vote,  in  person or by proxy,  at any  meeting  of
shareholders  of  Bancshares  (or any  action by  written  consent  in lieu of a
meeting) to approve the Agreement and the transactions contemplated thereby (the
"Shareholders' Meeting"), all of the CCBC Shares as to which the undersigned has
sole or shared voting power (the "Shares") as of the record date  established to
determine shareholders who have the right to vote at the Shareholders' Meeting.

     The  undersigned  agrees  that,  from and after the date of this letter and
through  the  date  of the  Shareholders'  Meeting  (and  any  postponements  or
adjournments  thereof),  the  shareholder  will not sell,  assign,  transfer  or
otherwise take any action that will alter or affect in any way the right to vote
the Shares,  except (i) with the prior written consent of Bancorp (ii) to change
such right from that of a shared right of the  shareholder to vote the Shares to
a sole right of the shareholder to vote the Shares.

     The  undersigned  represents and warrants that the  undersigned has sole or
shared  voting power over ________  Shares  covered by the terms of this letter;
and there are no proxies, voting trusts or other agreements or understandings to
which the undersigned or the  undersigned's  spouse, if any, is a party or bound
or that  requires  that any of the Shares be voted in any specific  manner other
than as provided in this letter.

     The  undersigned  is currently  determined to be an affiliate of Bancshares
for purposes of Rule 145 promulgated by the Securities and Exchange  Commission.
The following  undertaking is given  pursuant to and in compliance  with Section
7.12 of the  Agreement.  The Merger  will  result in the  issuance of new common
stock of Bancorp.

     The undersigned  understands that Bancorp and Bancshares are relying on the
performance of the covenants contained herein to insure that any sales of shares
owned by the  undersigned  are not deemed to be acting as an  underwriter  in an
unregistered public offering in violation of federal securities laws.

     The undersigned  hereby further agrees not to sell,  transfer or dispose of
any shares of Bancorp acquired in the Merger, or to attempt to do so, whether or
not  deemed to be an  affiliate  of  Bancorp,  unless  such  sale,  transfer  or
disposition is made:

     (i)pursuant to a then-current, effective registration statement under the 
Securities Act of 1933, or

     (ii)in a transaction  which, in the opinion of counsel  satisfactory to the
issuer, is not required to be registered under the Securities Act of 1933.

     The undersigned  understands  that Bancorp shares issued to the undersigned
will bear a restrictive  legend to this effect.  The  undersigned has no present
intention of selling, and has made no arrangements to sell, Bancorp shares to be
issued to the undersigned in connection with the Merger.

     The  undersigned  and  Bancorp  each  acknowledge  that,  in  view  of  the
uniqueness of the obligations of the  undersigned in this letter,  Bancorp would
not have an  adequate  remedy at law for  money  damages  in the event  that the
promises in this letter have not been  performed  according  to its terms,  and,
therefore,  the  undersigned  agrees that Bancorp  shall be entitled to specific
enforcement  of the terms hereof in addition to any other remedy to which it may
be entitled at law or in equity.

     This letter shall  terminate  automatically  without  further action at the
earlier of the  Effective  Date under the  Agreement or the  termination  of the
Agreement in accordance with its terms.

     This Agreement may be executed in one or more  counterparts,  each of which
shall be deemed to be an original  instruments,  but all of which together shall
constitute one and the same instrument.

     IN WITNESS  WHEREOF,  the undersigned has executed this Agreement as of the
date first above written.

                           Very truly yours,

     I,  ____________________,  hereby  confirm that I have read and  understand
this letter and agree that it shall bind my interest in the Shares, if any.

California Community Bancshares Corporation
141 Parker Street
Vacaville, California 95688-3985

                      SierraWest Bancorp - Bancshares Bank

Ladies and Gentlemen:

         We  have  acted  as  counsel  for  SierraWest  Bancorp  ("Bancorp"),  a
California  corporation,  and  SierraWest  Bank  ("Sierra  Bank"),  a California
banking corporation with respect to the acquisition and merger (the "Merger") of
California  Community  Bancshares  Corporation   ("Bancshares"),   a  California
corporation,  with and into  Bancorp  and with  respect to the merger (the "Bank
Merger") of Continental Pacific Bank ("CPB"), a California banking  corporation,
with and into Sierra Bank,  pursuant to the Plan of Acquisition and Merger dated
as of November __, 1997 (the "Agreement") and Exhibit A (the "Merger Agreement")
and Exhibit B (the "Bank Merger Agreement") thereto. This opinion is rendered to
you pursuant to Section 8.6 of the Agreement.  Unless otherwise  defined herein,
all capitalized terms in this opinion shall have the meaning assigned to them in
the Agreement.

         In rendering the opinions hereinafter  expressed,  we have examined and
relied  upon such  documents  and  instruments  as we have  deemed  appropriate,
including the following:

         A.   The Agreement and the exhibits thereto;

         B.  Resolutions  of the board of  directors  of Bancorp and Sierra Bank
with respect to the Merger and the Bank Merger;

         C. Articles of  Incorporation  of Bancorp  certified by the  California
Secretary of State as of a recent date;

         D. Articles of Incorporation of Sierra Bank certified by the California
Secretary of State as of a recent date;

         E.   Bylaws, minute book and stock ledger of Bancorp;

         F.   Bylaws and minute book of Sierra Bank;

         G.  Certificate  of  Status  from  the  California  Secretary  of State
indicating  that Bancorp is in good  standing in  California as of a recent date
(the "Bancorp Status Certificate");

         H. Certificate of Status from the California  Secretary indicating that
Sierra Bank is in good  standing in  California as of a recent date (the "Sierra
Bank Status Certificate");

         I. Registration  Statement on Form S-4 of Bancorp and the related Proxy
Statements  of  Bancshares  and Bancorp  with respect to the Merger and the Bank
Merger (the "Proxy Materials");

         J.   Proceedings of the meeting of shareholders of Bancorp held on 
______________, 19__; and

         K.  Officers'  certificates  of Bancorp  and Sierra  Bank as to certain
factual matters.

         We have  obtained,  and have  assumed  and  relied  upon the  accuracy,
genuineness and  completeness  of, such  certificates and assurances from public
officials as we have deemed  necessary or appropriate to enable us to render our
opinion.

         In conducting our examination,  we have assumed, without investigation,
the genuineness of all signatures (other than that of Bancorp and Sierra Bank to
the Agreement and to the Merger  Agreement),  the  correctness  of all documents
submitted  to us as  originals,  the  conformity  to original  documents  of all
documents   submitted  to  us  as  certified  or  photostatic   copies  and  the
authenticity   of  the   originals   of  such   copies;   the  accuracy  of  the
representations as to factual matters made by Bancorp,  Sierra Bank,  Bancshares
and CPB in the Agreement;  the accuracy of representations  and statements as to
factual  matters made by officers and employees of Bancshares  and CPB; that the
Agreement  is the valid and  binding  obligation  of  Bancshares  and CPB;  that
Bancshares  and CPB will  enforce the  Agreement  in a  commercially  reasonable
manner; and that the Agreement contains the entire agreement of the parties.

         Our opinions in  paragraphs 4 and 5 below are subject to :

                           (i) the  effect of  bankruptcy,  insolvency,  
reorganization,  arrangement,  moratorium, and other similar laws now or here-
after in effect relating to or affecting the rights of creditors generally;

                           (ii)  limitations  imposed by California law, federal
law, or equitable principles upon any of the remedies,  covenants,  or other  
provisions of the Agreement and upon the availability of injunctive  relief or 
other equitable  remedies,  including, without  limitation,  the effect of  
California  and  federal  court  decisions, invoking  statutes  or  principles 
of  equity,  which  have held  that  certain covenants and provisions of 
agreements are  unenforceable  where: (A) the breach of such covenants or 
provisions imposes  restrictions or burdens upon one party, and it cannot be  
demonstrated  that the  enforcement  of such  restrictions  or burdens is 
reasonably  necessary for the protection of the other party, or (B) a party's  
enforcement  of such  covenants or provisions  under the  circumstances would 
violate such party's implied covenants of good faith and fair dealing, and

                           (iii)  the power of  federal  and state  courts  to
refuse to  enforce  (or to stay the enforcement  of) any  provision  of the  
Agreement  which  purports to waive the rights of Bancorp and Sierra Bank to 
assert the claims or defenses  available to Bancorp and Sierra Bank by statute,
common law, or equity.

         Whenever a statement herein with respect to the existence or absence of
facts is qualified by the phrases "we are not aware" or "to our  knowledge,"  it
is intended to indicate that, during the course of our representation of Bancorp
and Sierra Bank, no information  that would give us current actual  knowledge of
the inaccuracy of such statement has come to the attention of those attorneys in
this firm who have rendered legal services in connection with the representation
described  in the  introductory  paragraph  of  this  opinion  letter  and  such
statement is based solely upon (i) an inquiry of attorneys  within this firm who
have rendered such services;  (ii) receipt of one or more certificates  executed
by officers of Bancorp or Sierra Bank covering such matters;  and (iii) opinions
of other  counsel  engaged by Bancorp or Sierra Bank  regarding  any  litigation
matters  with  respect  to which we do not  represent  Bancorp  or Sierra  Bank.
However,  we have not undertaken any independent  investigation to determine the
accuracy of such statement,  and any limited inquiry undertaken by us during the
preparation   of  this  opinion  letter  should  not  be  regarded  as  such  an
investigation;  no inference as to our  knowledge of any matters  bearing on the
accuracy  of  any  such  statement   should  be  drawn  from  the  fact  of  our
representation of Bancorp or Sierra Bank.

         Based upon and subject to the foregoing, we are of the opinion that:

         1. Bancorp is a corporation duly incorporated,  validly existing and in
good standing  under the laws of the State of  California  and has the corporate
power to own all of its  property  and assets and to carry on its business as it
is now being  conducted.  Bancorp is a registered bank holding company under the
Bank Holding Company Act of 1956.

         2. Sierra Bank is a California  banking  corporation duly incorporated,
validly  existing and in good standing under the laws of the State of California
and has the  corporate  power to own all of its property and assets and to carry
on its business as it is now being conducted.  Sierra Bank is duly licensed as a
commercial bank by the California Department of Financial Institutions,  and its
deposits are insured by the Federal Deposit Insurance  Corporation in accordance
with applicable laws and regulations.

         3.  Bancorp  and Sierra  Bank have the  corporate  power and  corporate
authority  to enter into and  perform  their  respective  obligations  under the
Agreement, the Merger Agreement and the Bank Merger Agreement. The execution and
delivery by Bancorp and Sierra Bank of the Agreement, the execution and delivery
by Bancorp of the Merger  Agreement and the execution by Sierra Bank of the Bank
Merger Agreement did not, and the consummation by Bancorp and Sierra Bank of the
transactions  contemplated by the Agreement,  the Merger  Agreement and the Bank
Merger  Agreement will not,  violate any provision of Bancorp's or Sierra Bank's
articles of incorporation or bylaws, any provision of federal or California law,
or any  governmental  regulation  applicable  to  Bancorp  or  Sierra  Bank,  or
constitute a material  default under, or result in the breach or acceleration of
any obligation or the creation of any material lien under any material agreement
to which either  Bancorp or Sierra Bank is bound and of which we have  knowledge
(except that we express no opinion relating to the effect of the Agreement under
any  financial  test or  ratio  contained  in any  mortgage,  lease,  agreement,
instrument,  judgment,  decree,  order,  arbitration  award, writ, or injunction
applicable to Bancorp or Sierra Bank).

         4. The Agreement and the Merger  Agreement  have been duly  authorized,
executed  and  delivered  by  Bancorp,  and each of them is a valid and  binding
agreement of Bancorp.

         5.  The  Agreement  and  the  Bank  Merger  Agreement  have  been  duly
authorized,  executed and delivered by Sierra Bank,  and each of them is a valid
and binding agreement of Sierra Bank.

         6. All  California  state and  federal  regulatory  approvals  that are
required to be obtained by Bancorp and Sierra Bank in connection with the Merger
and the Bank Merger have been obtained.

         7. To our knowledge, neither Bancorp nor Sierra Bank is a party to, nor
threatened with, any legal action or other  proceeding or  investigation  before
any court,  any arbitrator of any kind or any government  agency that challenges
or questions  the  authority or ability of Bancorp or Sierra Bank to perform its
obligations  under  the  Agreement,  the  Merger  Agreement  or the Bank  Merger
Agreement or to carry out the Merger or the Bank Merger,  or where the amount in
controversy  exceeds  $200,000  and which has not been  disclosed  by Bancorp to
Bancshares.

         8. As of October 31,  1997,  the  authorized  capital  stock of Bancorp
consists of [9,800,000] shares of preferred stock,  [200,000] shares of series A
preferred  stock and  [10,000,000]  shares of common stock. To our knowledge and
before giving effect to the issuance of shares in connection with the Merger:

         (a)  [3,324,764]  shares of Bancorp  common stock are duly  authorized,
validly issued and outstanding, fully paid and nonassessable;

         (b) there are  currently  outstanding  options  to  purchase  [371,355]
shares of common stock issued pursuant to the 1996 Stock Option Plan;

             SIERRAWEST BANCORP AND CALIFORNIA COMMUNITY BANCSHARES
                  CORPORATION SIGN DIFINITIVE MERGER AGREEMENT

                 Transaction Valued at Approximately $39 Million

TRUCKEE,  Calif. and Vacaville,  Calif.(November 14, 1997) -- SierraWest Bancorp
(Nasdaq:  SWBS) and California Community Bancshares Corp.  (Nasdaq:CCBC) jointly
announced  today  that they  have  signed a  definitive  agreement  under  which
SierraWest  will acquire the  outstanding  common stock of California  Community
Bancshares  in a  transaction  valued at  approximately  $39  million,  based on
yesterday's closing price of SierraWest stock.

         The Boards of Directors of both companies have unanimously approved the
merger agreement.  The merger,  which is expected to close during the first half
of 1998, is subject to the approval of each company's shareholders and state and
federal regulatory agencies, as well as certain other terms and conditions.

         Under the terms of the proposed transaction, shareholders of California
Community  Bancshares  will  receive  shares of  SierraWest  common  stock at an
exchange  ratio to be determined by a formula prior to the effective date of the
transaction,  based on the average of the closing  prices of  SierraWest  common
stock during a defined 20-day period.  For example,  if the average price during
that  20-day  period  were  $28.75,  the closing  price of  SierraWest  stock on
November 13, 1997, each share of California  Community Bancshares stock would be
exchanged for approximately 0.9957 shares of SierraWest.  The merger is expected
to be accounted for under the pooling of interests method of accounting.

         "We are  very  pleased  with the  opportunity  to  expand  SierraWest's
community banking franchise into Solano and Contra Costa counties," said William
T. Fike,  president and chief executive officer of SierraWest.  "During the past
three years,  we have extended our  franchise as far as  Sacramento  through new
branch openings,  the July 1997 acquisition of Mercantile Bank and the hiring of
experienced lending officers to serve the Sacramento region. Continental Pacific
Bank will  strengthen our franchise along the Interstate 80 corridor by adding a
strong  business  banking   franchise  staffed  by  senior  lending  and  branch
personnel.  We  strongly  believe  that  this  merger,  which  creates a banking
franchise with more than $750 million in assets,  opens up new opportunities for
our combined  operations and will provide  benefits to SierraWest's  current and
new shareholders."

         Walter O.  Sunderman,  president and chief  executive  officer of CCBC,
said,  "We are excited about joining with  SierraWest to build  together a great
California  banking  franchise  and  about  owning  one of  the  best-performing
California bank stocks.  The banking industry in California is changing rapidly,
largely  due  to  consolidation.  We  concluded  that  merging  with  SierraWest
presented  an  outstanding  opportunity  for  our  shareholders,  employees  and
customers throughout Solano and Contra Costa counties. SierraWest is a community
bank that  shares our  philosophy  of  providing  customers  with  personalized,
professional service."

         California  Community  Bancshares has also granted SierraWest an option
to  purchase  up to 19.9%  of the  outsanding  shares  of  California  Community
Bancshares if certain events and conditions (as defined in the option agreement)
occur, including a third party merger proposal or tender offer.

         California  Community  Bancshares,  the parent  company of  Continental
Pacific Bank, is headquartered  in Vacaville,  California and had assets of $192
million at September 30, 1997.  Continental  Pacific Bank operates eight banking
offices in Solano and Contra Costa counties in California.

         SierraWest   Bancorp  is  the  holding   company  for  SierraWest  Bank
headquarted  in Truckee,  California  with  branches in  Sacramento,  the Sierra
foothills and Lake Tahoe regions of California and northern  Nevada.  SierraWest
had assets of $575 million at September  30, 1997.  The Company is a significant
originator under the U.S.  Government's  SBA loan program,  with recent SBA loan
offices opened in Portland, Oregon and in Chattanooga, Tennessee.
