                            PART I

ITEM 1.     BUSINESS.

(A)  GENERAL.

    Certain statements in this Annual Report on Form 10-K include forward-
looking information within the meaning of Section 27A of the Securities Act of
1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as
amended, and are subject to the "safe harbor" created by those sections.  These
forward-looking statements involve certain risks and uncertainties that could
cause actual results to differ materially from those in the forward-looking
statements.  Such risks and uncertainties include, but are not limited to, the
following factors: competitive pressure in the banking industry increases
significantly; changes in the interest rate environment reduce margins; general
economic conditions, either nationally or regionally, are less favorable than
expected, resulting in, among other things, a deterioration in credit quality
and an increase in the provision for possible loan losses; changes in the
regulatory environment; changes in business conditions, particularly in Napa
County and the wine industry; volatility of rate sensitive deposits; operational
risks including data processing system failures or fraud; asset/liability
matching risks and liquidity risks; and changes in the securities markets.  See
also "Certain Additional Business Risks" included herein in Item 1 and other
risk factors discussed elsewhere in this Report.

    Napa National Bancorp (the "Company") was incorporated in 1981 in the State
of California and is headquartered in Napa, California.  The Company is a bank
holding company.  Its subsidiary, Napa National Bank (the "Bank"), was organized
as a national banking association in 1982.  At December 31, 1996, the Company
had consolidated assets of $113,827,000 and shareholders' equity of $7,971,000.
The Bank is a full service commercial bank with three offices serving the Napa
Valley area in Northern California.  The Company itself does not engage in any
business activities other than the ownership of the Bank and the ownership of
Napa National Leasing Corporation, an inactive subsidiary authorized to engage
in the leasing of equipment and other personal property (the "Leasing Company").
W. Clarke Swanson, Jr., Chairman of the Board and CEO, beneficially owns
approximately 70% of the outstanding shares of Common Stock of the Company.  The
Company is registered under the Bank Holding Company Act of 1956, as amended.

    The Bank provides a wide range of commercial banking services to
individuals, professionals and small- and medium-sized businesses in the Napa
Valley area.  The services provided include those typically offered by
commercial banks, such as: checking, interest checking, savings, and time
deposit accounts, commercial, construction, personal, home improvement,
mortgage, automobile and other installment and term loans, travelers' checks,
night depository facilities, wire transfers, merchant card services, courier
service and automated teller machines.

    The Bank does not provide international banking or trust services but has
arranged for its correspondent banks to offer these and other services to its
customers on an as needed basis.

                                                                               3
<PAGE>
 
    Individuals, small businesses and professionals, manufacturers,
distributors, retailers, wineries, vineyard owners, real estate developers and
the Bank's shareholders currently form the core of the Bank's customer and
deposit base. In order to attract these customers, the Bank offers extensive
personalized contact, specialized services and banking convenience, including
Saturday banking hours.


EXISTING LOCATIONS

    In addition to the Bank's head offices at 901 Main Street in Downtown Napa,
the Bank has two branch offices, one in St. Helena and one in North Napa.  All
three facilities offer full service to the Bank's customers.  See "Item 2. -
Properties" herein.


DEPOSITS

    Most of the Bank's deposits are obtained from individuals, professional
firms and small- to medium-sized businesses from the Bank's service area. As of
December 31, 1996, the Bank had a total of 9,580 accounts representing 6,292
demand accounts with an average balance of approximately $8,664 each, 2,106
savings accounts with an average balance of approximately $5,708 each, and 1,182
other time accounts with an average balance of approximately $30,489 each.


OTHER BORROWINGS

    At December 31, 1996 and 1995, the Bank had no borrowed funds.


LENDING ACTIVITIES

    The Bank concentrates its lending activities in four areas:  commercial
loans, short-term real estate and construction loans, mortgage loans, and loans
to individuals or households, automobile and other personal expenditures.  At
December 31, 1996, these four loan categories accounted for approximately 66%,
11%, 6% and 17%, respectively, of the Bank's loan portfolio.  Within these
categories, $10,933,000, or 14%, of the loan portfolio, relates to the winery
and vineyard segment of the agricultural industry with commitments to lend an
additional $4,670,000.

    Under federal regulations applicable to national banks, at December 31,
1996, in general, the Bank cannot make loans to one borrower in excess of
$1,390,000. For borrowers desiring loans in excess of the Bank's lending limit,
the Bank may make such loans on a participation basis with other banks, without
recourse to the Bank.  In other cases, the Bank may refer such borrowers to
larger banks or lending institutions.  The interest rates charged for the
various loans made by the Bank vary with the degree of risk, size and maturity
of the loans involved and are generally affected by competition, governmental
regulation and current money market rates.

    The Bank's construction and mortgage loans are not concentrated in any one
category and include loans to individuals, partnerships and corporations. As of
December 31, 1996, the Bank had gross loans outstanding of $79,695,000 and
undisbursed loan commitments of $21,351,000.

                                                                               4
<PAGE>
 
COMMITMENTS AND LINES OF CREDIT

    The Bank makes contractual commitments to extend credit.  Such commitments
are usually made in the form of revolving lines of credit or term loans with one
or more takedowns.  Such commitments typically mature within one to three years.
The Bank also extends standby letters of credit which support the obligations of
Bank customers to third parties.  At December 31, 1996, the Bank had $20,467,000
in commitments to extend credit and $865,000 in standby letters of credit.


CORRESPONDENT BANKS

    At December 31, 1996, the Bank had correspondent relationships with Wells
Fargo Bank, Bank of America National Trust and Savings Association, and Union
Bank of California.  These relationships are a result of the Bank's efforts to
obtain a wide range of services for the Bank and its customers and, as a net
seller of federal funds (overnight interbank loans), to minimize the risk of
undue concentration of its resources with a few entities.  The Bank does not
currently serve, nor does it have plans to serve, as a correspondent to other
banks.


EMPLOYEES

    At December 31, 1996, the Bank employed 75 employees, including 26 officers
and 12 part-time employees.  At December 31, 1996, the Company employed one
employee.

     This subsidiary was inactive during 1996.

RATE AND VOLUME ANALYSIS

    The following tables set forth, for the periods indicated, a summary of the
changes in average interest bearing asset and liability balances (volume) and
changes in average interest rates (rate). Where significant, the change in
interest due to both volume and rate has been allocated to the change due to
volume and rate in proportion to the relationship of absolute dollar amounts in
each. Insignificant changes have been allocated solely to the change due to
volume.

    The Company had Federal Reserve and Federal Home Loan Bank Stock totalling
$554,000 and $197,000, at December 31, 1996 and 1995, respectively.

    Yields on securities have been calculated by dividing interest income,
adjusted for amortization of any premium and accretion of any discount, by the
book value of the related securities.  The Company's Federal Reserve and Federal
Home Loan Bank Stocks have no maturity and a weighted average yield of 6.0%.
All of the Company's U.S. Treasury securities have a maturity of less than
twelve months and a weighted average yield of 5.4%.

LOAN PORTFOLIO

    The Company's primary service area is Napa County and the Carneros growing
region of Sonoma County.  The Company's portfolio of loans consists of real
estate mortgage and construction loans, commercial and consumer loans.

    At December 31, 1996, the Company's real estate construction portfolio
totaled $8,706,000.  Real estate loans consisted of single family residences to
developers and owner-builders with a history of successfully developing projects
in the Company's market area.  The loan-to-value ratio on each real estate
construction loan required by the Company depends upon the amount of the loan,
the nature of the property, whether the property is residential or commercial
and whether or not it is owner occupied.  For construction loans, the Company's
policy is to require that the loan-to-value ratio generally be no more than 70%
when the loan is initially made and that the borrower generally has no less than
a 50% equity interest in the land.  Substantially all of the real estate
construction portfolio is secured by real estate located within the Company's
service area.

                                                                              11
<PAGE>
 
    Conventional real estate loans totaled $4,918,000 at December 31, 1996. The
loan-to-value ratio required by the Company on conventional real estate loans
depends upon the nature of the property and whether or not it is owner-occupied.
For owner-occupied conventional real estate loans, the Company usually requires
that the loan-to-value ratio be no more than 80% except when private mortgage
insurance is required, whereupon the Company may allow the loan-to-value ratio
to rise generally to no more than 85% when the loan is initially made.
Generally, non-owner-occupied conventional real estate loans must have loan-to-
value ratios not exceeding 70% when the loan is made.  The entire real estate
mortgage portfolio is generally secured by first or second deeds of trust.
Substantially all of the secured property is located within the Company's
service area.

    At December 31, 1996, commercial loans totaled $52,789,000.  Commercial
lending is primarily to professionals and companies with sales up to $10
million.  The Company's lending relationships generally involve companies with
sales of no more than $30 million.  Substantially all of the commercial loan
portfolio is secured, some of which may include real estate collateral. Such
loans are not intended as permanent financing of real estate but are made for
commercial purposes and are secured by commercial real estate.  The Company
evaluates such loans based upon the borrower's ability to service the debt
through its business operations and does not rely primarily on the value of the
real estate collateral for repayment.  The remaining portfolio is secured by
accounts receivables, inventory, equipment, stock and deposits held by the
Company.

    Total consumer loans, including personal lines of credit, were $13,282,000
at December 31, 1996.  Included in consumer loans to individuals are home equity
lines of credit, totaling $9,066,000, which are secured primarily by second
trust deeds on single family residences.  The Company requires a debt-to-value
ratio of not higher than 75% for most home equity loans when the loan is
initially made.  The remaining portfolio is collateralized by automobiles,
computers and other equipment, and deposits held by the Company.  Over 70% of
the Company's consumer portfolio is secured.

    The Company had standby letters of credit outstanding of $865,000 and
$646,000 at December 31, 1996 and December 31, 1995, respectively.  In addition,
the Company had commitments to fund real estate construction loans, commercial
loans and consumer loans of $2,684,000, $17,670,000 and $997,000, respectively,
at December 31, 1996.

    The Company did not have any loans related to lease financing activities in
the loan portfolio at December 31, 1996.

                                                                              12

    In recent years, California commercial real estate markets in general have
experienced some difficulties.  While these developments have not, in the
judgment of management, had a material adverse impact on the Bank's business,
there can be no assurance that further softening of the California real estate
market will not occur, nor can any assurance be given as to the effect of any
such developments on the Bank's business.  Further increases in interest rates
could adversely impact real estate values or the ability of borrower to satisfy
the material terms of such loans.

    During the beginning of 1997, the Napa Valley was subjected to severe
weather conditions that resulted in some areas of the Valley flooding from high
rain fall levels.  Most of the flooding resulted in areas near the Napa River on
dormant fields.  Management believes that this flooding did not have a direct or
material impact on the collateral underlying portions of the existing loan
portfolio.


LOAN CONCENTRATIONS

    At December 31, 1996, approximately $55,680,000, or 70% of the loan
portfolio was secured by commercial or residential real estate. Concentrations
of the Bank's lending activity in the real estate sector could have the effect
of intensifying the impact on the Bank if there are any adverse changes in the
real estate market in the Bank's lending area.

    The Bank is located in the Napa Valley and a significant amount of its loans
are related to winery and vineyard operations.  Loans related to winery and
vineyard operations constituted approximately $10,933,000, or 14% of total loans
at December 31, 1996, as compared to $6,913,000, or 9% of total loans, at
December 31, 1995.  A downturn in the wine industry in the Napa Valley or a
disruption in wine production, which may result from extreme weather conditions,
plant diseases or other natural causes, competition, changes in governmental
regulatory or tax policies, or changes in consumer preferences, could have a
significant adverse impact on the Company's results of operations and financial
condition.

                                                                              13

     Total Nonperforming Assets     $3,480     $1,447
 
</TABLE>

    Management analyzes each loan on a case by case basis to determine when, in
management's opinion, interest should no longer be accrued.  This occurs when
management determines the ultimate collectibility of principal or interest to be
unlikely or when loans become 90 days or more past due, unless they are well
secured and in the process of collection or unless other circumstances exist
which justify the treatment of the loan as fully collectible.  When a loan is
placed on nonaccrual status, unpaid interest is reversed and charged against
current income.

    Interest income on nonaccrual loans at December 31, 1996 which would have
been recognized during the year if the loans had been current in accordance with
their original terms totaled $188,000 versus $291,000 for the same period in
1995.

    As of December 31, 1996 and 1995, other real estate owned totaled $328,000
and $0, respectively.  It is the Company's policy to write foreclosed property
down to the lower of fair market value less estimated selling costs or cost at
the time it is reclassified into other real estate owned.  Miscellaneous
expenses relating to the property are charged to other noninterest expenses as
incurred.

    As of the date of this filing, there were no other loans, other than those
included in the table above, where known information concerning possible credit
problems of borrowers caused management to have serious doubts as to the ability
of the borrower to comply with the present loan repayment terms such that they
may become nonperforming loans. See "Nonperforming Assets" herein.

    At December 31, 1996, pursuant to SFAS 114, the Company's total recorded
investment in nonaccrual loans was $3,152,000, of which there was a related
allowance for credit losses of $204,000.

     The average recorded investment in nonaccrual loans during 1996 was
$2,123,000.  Related interest income recognized on impaired loans during the
year ended December 31, 1996, under the cash-basis method of accounting was
approximately $44,000.

                                                                              14

SUMMARY OF LOAN LOSS EXPERIENCE

    Inherent in the lending function is the fact that loan losses will be
experienced and that the risk of loss will vary with the type of loan being made
and the credit-worthiness of the borrower over the term of the loan. The Company
has an allowance for loan losses which is maintained at a level estimated to be
adequate to provide for losses that can be reasonably anticipated based upon
specific loan conditions as determined by management, historical loan loss
experience, the amount of past due and nonperforming loans, comments of third-
party loan review consultants, prevailing economic conditions and other factors.
While these factors are essentially judgmental and may not be reduced to a
mathematical formula, it is management's view that the $1,405,000 allowance,
which constitutes 1.76% of total loans at December 31, 1996, was adequate as an
allowance against foreseeable losses from the loan portfolio.  The allowance was
$1,325,000, or 1.77%, of the total loan portfolio at December 31, 1995.  The
allowance is increased by charges to the provision for loan losses and reduced
by net charge-offs.  The continuing evaluation of the loan portfolio and
assessment of current economic conditions will dictate future allowance levels.

    An analysis of the allowance for loan losses for the years ending December
31, 1996 and 1995 follows:

    The table set forth below shows a breakdown of the portfolio of loans at the
dates indicated and the amount of the allowance that has been allocated as of
those dates to each of the loan categories.  Management believes that any
breakdown or allocation of the allowance for possible loan losses into loan
categories lends an appearance of exactness which does not exist, in that the
reserve is ultimately utilized as a single unallocated allowance available for
all loans.

THE EFFECT OF GOVERNMENT POLICY ON BANKING

     The earnings and growth of the Bank are affected not only by local market
area factors and general economic conditions, but also by government monetary
and fiscal policies.  For example, the Board of Governors of the Federal Reserve
System ("FRB") influences the supply of money through its open market operations
in U.S. Government securities and adjustments to the discount rates applicable
to borrowings by depository institutions and others.  Such actions influence the
growth of loans, investments and deposits and also affect interest rates charged
on loans and paid on deposits.  The nature and impact of future changes in such
policies on the business and earnings of the Bank cannot be predicted.
Additionally, state and federal tax policies can impact banking organizations.
Effective January 1, 1997, applicable California bank and corporation tax rates
were reduced by 5% in order to keep California competitive with other western
states.

     As a consequence of the extensive regulation of commercial banking
activities in the United States, the business of the Company is particularly
susceptible to being affected by the enactment of federal and state legislation
which may have the effect of increasing or decreasing the cost of doing
business, modifying permissible activities or enhancing the competitive position
of other financial institutions.  Any change in applicable laws or regulations
may have a material adverse effect on the business and prospects of the Company.
In response to various business failures in the savings and loan industry and in
the banking industry, in December 1991, Congress enacted, and the President
signed into law, the Federal Deposit Insurance Corporation Improvement Act of
1991 ("FDICIA"). FDICIA substantially revised the bank regulatory framework and
deposit insurance funding provisions of the Federal Deposit Insurance Act and
made revisions to several other federal banking statutes.

     Implementation of the various provisions of FDICIA is subject to the
adoption of regulations by the various regulatory agencies, the manner in which
the regulatory agencies implement those regulations and certain phase-in
periods.


REGULATION AND SUPERVISION OF BANK HOLDING COMPANIES

     The Company is a bank holding company subject to the Bank Holding Company
Act of 1956, as amended ("BHCA").  The Company reports to, registers with, and
may be examined by, the FRB.  The FRB also has the authority to examine the
Company's subsidiaries.  The costs of any examination by the FRB are payable by
the Company.

     The FRB has significant supervisory and regulatory authority over the
Company and its affiliates.  The FRB requires the Company to maintain certain
levels of capital.  See "Capital Standards."  The FRB also has the authority to
take enforcement action against any bank holding company that commits any unsafe
or unsound practice, or violates certain laws, regulations or conditions imposed
in writing by the FRB.  See "Prompt Corrective Action and Other Enforcement
Mechanisms."

                                                                              18
<PAGE>
 
     Under the BHCA, a company generally must obtain the prior approval of the
FRB before it exercises a controlling influence over a bank, or acquires
directly or indirectly, more than 5% of the voting shares or substantially all
of the assets of any bank or bank holding company.  Thus, the Company is
required to obtain the prior approval of the FRB before it acquires, merges or
consolidates with any bank or bank holding company; any company seeking to
acquire, merge or consolidate with the Company also would be required to obtain
the approval of the FRB.

     The Company is generally prohibited under the BHCA from acquiring ownership
or control of more than 5% of the voting shares of any company that is not a
bank or bank holding company and from engaging directly or indirectly in
activities other than banking, managing banks, or providing services to
affiliates of the holding company.  A bank holding company, with the approval of
the FRB, may engage, or acquire the voting shares of companies engaged, in
activities that the FRB has determined to be so closely related to banking or
managing or controlling banks as to be a proper incident thereto.  A bank
holding company must demonstrate that the benefits to the public of the proposed
activity will outweigh the possible adverse effects associated with such
activity.

     Pursuant to the Riegle-Neal Interstate Banking and Branching Efficiency Act
of 1994 (the "Interstate Banking and Branching Act"), a bank holding company
became able to acquire banks in states other than its home state beginning
September 29, 1995 without regard to the permissibility of such acquisitions
under state law, but subject to any state requirement that the bank has been
organized and operating for a minimum period of time, not to exceed five years,
and the requirement that the bank holding company, prior to or following the
proposed acquisition, controls no more than 10% of the total amount of deposits
of insured depository institutions in the United States and no more than 30% of
such deposits in that state (or such lesser or greater amount set by state law).

     The Interstate Banking and Branching Act also authorizes banks to merge
across states lines, therefore creating interstate branches, beginning June 1,
1997.  Under such legislation, each state has the opportunity to "opt out" of
this provision, thereby prohibiting interstate branching in such states, or to
"opt in" at an earlier time, thereby allowing interstate branching within that
state prior to June 1, 1997. Furthermore, pursuant to such act, a bank is now
able to open new branches in a state in which it does not already have banking
operations, if the laws of such state permit such de novo branching.  California
enacted legislation to "opt in" to the Interstate Banking and Branching Act
provisions regarding interstate branching, allowing a state bank chartered in a
state other than California to acquire by merger or purchase, at any time after
effectiveness of the Caldera, Weggeland, and Killea California Interstate
Banking and Branching Act of 1995 ("IBBA"), a California bank or industrial loan
company which is at least five (5) years old and thereby establish one or more
California branch offices.  However, the IBBA prohibits a state bank chartered
in a state other than California from entering California by purchasing a
California branch office of a California bank or industrial loan company without
purchasing the entire entity or by establishing a de novo California branch
office.  See the section entitled "Recently Enacted Legislation" for additional
information.

     Proposals to change the laws and regulations governing the banking industry
are frequently introduced in Congress, in the state legislatures and before the
various bank regulatory agencies.

                                                                              19
<PAGE>
 
     The FRB generally prohibits a bank holding company from declaring or paying
a cash dividend which would impose undue pressure on the capital of subsidiary
banks or would be funded only through borrowing or other arrangements that might
adversely affect a bank holding company's financial position.  The FRB's policy
is that a bank holding company should not continue its existing rate of cash
dividends on its common stock unless its net income is sufficient to fully fund
each dividend and its prospective rate of earnings retention appears consistent
with its capital needs, asset quality and overall financial condition.

     Transactions between the Company and the Bank are subject to a number of
other restrictions.  FRB policies forbid the payment by bank subsidiaries of
management fees which are unreasonable in amount or exceed the fair market value
of the services rendered (or, if no market exists, actual costs plus a
reasonable profit).  Subject to certain limitations, depository institution
subsidiaries of bank holding companies may extend credit to, invest in the
securities of, purchase assets from, or issue a guarantee, acceptance, or letter
of credit on behalf of, an affiliate, provided that the aggregate of such
transactions with affiliates may not exceed 10% of the capital stock and surplus
of the institution, and the aggregate of such transactions with all affiliates
may not exceed 20% of the capital stock and surplus of such institution.  The
Company may only borrow from depository institution subsidiaries if the loan is
secured by marketable obligations with a value of a designated amount in excess
of the loan. Further, the Company may not sell a low-quality asset to a
depository institution subsidiary.

     Generally, a bank holding company and its subsidiaries are prohibited from
engaging in tie-in arrangements in connection with the extension of credit, sale
or lease of property or furnishing of services unless the FRB permits an
exception to the tying prohibitions pursuant to exemption authority available to
it under applicable law.  The FRB, however, has adopted a rule, effective
September 2, 1994, amending the anti-tying provisions to permit a bank or bank
holding company to offer a lower price on a loan, deposit or trust service
(traditional bank product), or on securities brokerage services, on the
condition that the customer obtain a traditional bank product from an affiliate.
Additionally, as of January 23, 1995, a bank holding company, or a nonbank
subsidiary, may offer lower prices on any of its products or services on the
condition that the customer obtain another product or service from such company
or any of its nonbank affiliates, provided that all products offered in the
package arrangement are separately available for purchase.

     The Company is a bank holding company within the meaning of Section 3700 of
the California Financial Code.  As such the Company and the Bank are subject to
examination by, and may be required to file reports with, the California
Superintendent of Banks (the "Superintendent").  Regulations have not yet been
proposed or adopted, and no other steps have been taken, to implement the
Superintendent's power under this statute.

                                                                              20

BANK REGULATION AND SUPERVISION

     As a national bank, the Bank is regulated, supervised and regularly
examined by the Office of the Comptroller of the Currency ("OCC").  Deposit
accounts at the Bank are insured by Bank Insurance Fund ("BIF"), as administered
by the Federal Deposit Insurance Corporation ("FDIC"), to the maximum amount
permitted by law.  The Bank is also subject to applicable provisions of
California law, insofar as such provisions are not in conflict with or preempted
by federal banking law.  The Bank is a member of the Federal Reserve System, and
is also subject to certain regulations of the FRB dealing primarily with check
clearing activities, establishment of banking reserves, Truth-in-Lending
(Regulation Z), Truth-in-Savings (Regulation DD), and Equal Credit Opportunity
(Regulation B).

     By comparison, California state-chartered banks are regulated by the
California Superintendent of Banks (the "Superintendent").  Pursuant to AB 3351,
which was adopted by the California legislature during 1996, all of the
California state regulatory authorities for state-chartered depository
institutions will be consolidated under a new state agency, the Department of
Financial Institutions ("DFI") effective July 1, 1997.  The newly created DFI
combines the State Banking Department and the Department of Savings and Loan
while regulatory oversight over industrial loan companies and credit unions will
be shifted from the Department of Corporations to the DFI.  During 1996 the
California Interstate Banking and Branching Cleanup Act was enacted, which
revised the Superintendent's assessment methodology for state-chartered banks in
order to provide a better basis of comparison to the method used by the OCC.
Under the new methodology, the average assessment for state banks will be
approximately 39% of the OCC's annual charges for national bank supervision.

     During 1996, the OCC adopted a regulation to revise and streamline its
procedures with respect to corporate activities of national banks, to be
effective December 31, 1996.  These revised standards allow the OCC to approve,
on a case-by-case basis, the entry of bank operating subsidiaries into a
business incidental to banking, including activities in which the parent bank is
not permitted to engage.  Such a standard allows a national bank to conduct an
activity approved for a bank holding company through a bank operating subsidiary
such as acting as an investment or financial advisor, leasing personal property
and providing financial advice to customers.  In general, these new standards
will be available to well-capitalized or adequately capitalized national banks.


CAPITAL STANDARDS

     The OCC and other federal banking agencies have risk-based capital adequacy
guidelines intended to provide a measure of capital adequacy that reflects the
degree of risk associated with a banking organization's operations for both
transactions reported on the balance sheet as assets and transactions, such as
letters of credit and recourse arrangements, which are recorded as off balance
sheet items.  Under these guidelines, nominal dollar amounts of assets and
credit equivalent amounts of off balance sheet items are multiplied by one of
several risk adjustment percentages, which range from 0% for assets with low
credit risk, such as certain U.S. government securities, to 100% for assets with
relatively higher credit risk, such as business loans.

                                                                              21

     In determining the capital level the Bank is required to maintain, the OCC
does not, in all respects, follow generally accepted accounting principles
("GAAP") and has special rules which have the effect of reducing the amount of
capital it will recognize for purposes of determining the capital adequacy of
the Bank.  These rules are called Regulatory Accounting Principles ("RAP").  In
December 1993, the federal banking agencies issued an interagency policy
statement on the allowance for loan and lease losses which, among other things,
establishes certain benchmark ratios of loan loss reserves to classified assets.
Future changes in OCC regulations or practices could further reduce the amount
of capital recognized for purposes of capital adequacy.  Such a change could
affect the ability of the Company to grow and could restrict the amount of
profits, if any, available for the payment of dividends.

     A banking organization's risk-based capital ratios are obtained by dividing
its qualifying capital by its total risk-adjusted assets and off balance sheet
items.  The regulators measure risk-adjusted assets and off balance sheet items
against both total qualifying capital (the sum of Tier 1 capital and limited
amounts of Tier 2 capital) and Tier 1 capital.  Tier 1 capital consists of
common stock, retained earnings, noncumulative perpetual preferred stock, other
types of qualifying preferred stock and minority interests in certain
subsidiaries, less most other intangible assets and other adjustments.  Net
unrealized losses on available-for-sale equity securities with readily
determinable fair value must be deducted in determining Tier 1 capital.
Additionally as of April 1, 1995, for Tier 1 capital purposes, deferred tax
assets that can only be realized if an institution earns sufficient taxable
income in the future will be limited to the amount that the institution is
expected to realize within one year, or ten percent of Tier 1 capital, whichever
is less.  Tier 2 capital may consist of a limited amount of the allowance for
possible loan and lease losses, term preferred stock and other types of
preferred stock not qualifying as Tier 1 capital, term subordinated debt and
certain other instruments with some characteristics of equity.  The inclusion of
elements of Tier 2 capital are subject to certain other requirements and
limitations of the federal banking agencies.  Since December 31, 1992, the
federal banking agencies have required a minimum ratio of qualifying total
capital to risk-adjusted assets and off balance sheet items of 8%, and a minimum
ratio of Tier 1 capital to adjusted average risk-adjusted assets and off balance
sheet items of 4%.

     In addition to the risked-based guidelines, federal banking regulators
require banking organizations to maintain a minimum amount of Tier 1 capital to
adjusted average total assets, referred to as the leverage capital ratio. For a
banking organization rated in the highest of the five categories used by
regulators to rate banking organizations, the minimum leverage ratio of Tier 1
capital to total assets must be 3%.  It is improbable, however, that an
institution with a 3% leverage ratio would receive the highest rating by the
regulators since a strong capital position is a significant part of the
regulators' rating.  For all banking organizations not rated in the highest
category, the minimum leverage ratio must be at least 100 to 200 basis points
above the 3% minimum.  Thus, the effective minimum leverage ratio, for all
practical purposes, must be at least 4% or 5%.  In addition to these uniform
risk-based capital guidelines and leverage ratios that apply across the
industry, the regulators have the discretion to set individual minimum capital
requirements for specific institutions at rates significantly above the minimum
guidelines and ratios.

                                                                              22

</TABLE>

     Banking agencies have recently adopted final regulations which mandate that
regulators take into consideration concentrations of credit risk and risks from
non-traditional activities, as well as an institution's ability to manage those
risks, when determining the adequacy of an institution's capital. This
evaluation will be made as a part of the institution's regular safety and
soundness examination. Banking agencies also have recently adopted final
regulations requiring regulators to consider interest rate risk (when the
interest rate sensitivity of an institution's assets does not match the
sensitivity of its liabilities or its off-balance-sheet position) in evaluation
of a bank's capital adequacy. This final rule does not codify a measurement
framework for assessing the level of a bank's interest rate risk exposure. The
information and exposure estimates collected through a new proposed supervisory
measurement process, described in the banking agencies' joint policy statement
on interest rate risk, would be one quantitative factor used to determine the
adequacy of an individual bank's capital for interest rate risk. The focus of
that proposed process is on a bank's economic value exposure. Other quantitative
factors include the bank's historical financial performance and its earnings
exposure to interest rate movements. Examiners also will consider qualitative
factors, including the adequacy of the bank's internal interest rate risk
management. The banking agencies intend for this case-by-case approach for
assessing a bank's capital adequacy for interest rate risk to be a transitional
arrangement.

     The second step will consist of a proposed rule that would establish an
explicit minimum capital charge for interest rate risk, based on the level of a
bank's measured interest rate risk exposure. The banking agencies intend to
implement this second step at some future date, after the banking agencies and
the banking industry have gained more experience with the proposed supervisory
measurement and assessment process.

                                                                              23

PROMPT CORRECTIVE ACTION AND OTHER ENFORCEMENT MECHANISMS

      FDICIA requires each federal banking agency to take prompt corrective
action to resolve the problems of insured depository institutions, including but
not limited to those that fall below one or more prescribed minimum capital
ratios. The law required each federal banking agency to promulgate regulations
defining the following five categories in which an insured depository
institution will be placed, based on the level of its capital ratios: well
capitalized, adequately capitalized, undercapitalized, significantly
undercapitalized and critically undercapitalized.

      In September 1992, the federal banking agencies issued uniform final
regulations implementing the prompt corrective action provisions of FDICIA. An
insured depository institution generally will be classified in the following
categories based on capital measures indicated below:

    "WELL CAPITALIZED"                    "ADEQUATELY CAPITALIZED"
    ------------------                    ------------------------
    Total risk-based capital of 10%;      Total risk-based capital of 8%;  
    Tier 1 risk-based capital of 6%; and  Tier 1 risk-based capital of 4%; and
    Leverage ratio of 5%.                 Leverage ratio of 4%.
 
    "UNDERCAPITALIZED"                    "SIGNIFICANTLY UNDERCAPITALIZED"
    ------------------                    --------------------------------  
    Total risk-based capital less than    Total risk-based capital less than 6%;
     8%;                                  Tier 1 risk-based capital less than 
    Tier 1 risk-based capital less than   3%; or
     4%; or                               Leverage ratio less than 3%.
    Leverage ratio less than 4%.
 
    "CRITICALLY UNDERCAPITALIZED"
    -----------------------------
    Tangible equity to total assets
     less than 2%.

    An institution that, based upon its capital levels, is classified as "well
capitalized," "adequately capitalized" or "undercapitalized" may be treated as
though it were in the next lower capital category if the appropriate federal
banking agency, after notice and opportunity for hearing, determines that an
unsafe or unsound condition or an unsafe or unsound practice warrants such
treatment. At each successive lower capital category, an insured depository
institution is subject to more restrictions. The federal banking agencies,
however, may not treat an institution as "critically undercapitalized" unless
its capital ratio actually warrants such treatment.

     If an insured depository institution is undercapitalized, it will be
closely monitored by the appropriate federal banking agency. Undercapitalized
institutions must submit an acceptable capital restoration plan with a guarantee
of performance issued by the holding company. Further restrictions and sanctions
are required to be imposed on insured depository institutions that are
critically undercapitalized. The most important additional measure is that the
appropriate federal banking agency is required to either appoint a receiver for
the institution within 90 days, or obtain the concurrence of the FDIC in another
form of action.

                                                                              24
<PAGE>
 
    In addition to measures taken under the prompt corrective action provisions,
commercial banking organizations may be subject to potential enforcement actions
by the federal regulators for unsafe or unsound practices in conducting their
businesses or for violations of any law, rule, regulation or any condition
imposed in writing by the agency or any written agreement with the agency.
Enforcement actions may include the imposition of a conservator or receiver, the
issuance of a cease-and-desist order that can be judicially enforced, the
termination of insurance of deposits (in the case of a depository institution),
the imposition of civil money penalties, the issuance of directives to increase
capital, the issuance of formal and informal agreements, the issuance of removal
and prohibition orders against institution-affiliated parties and the
enforcement of such actions through injunctions or restraining orders based upon
a judicial determination that the agency would be harmed if such equitable
relief was not granted. Additionally, a holding company's inability to serve as
a source of strength to its subsidiary banking organizations could serve as an
additional basis for a regulatory action against the holding company.


SAFETY AND SOUNDNESS STANDARDS

     FDICIA also implemented certain specific restrictions on transactions and
required federal banking regulators to adopt overall safety and soundness
standards for depository institutions related to internal control, loan
underwriting and documentation and asset growth. Among other things, FDICIA
limits the interest rates paid on deposits by undercapitalized institutions,
restricts the use of brokered deposits, limits the aggregate extensions of
credit by a depository institution to an executive officer, director, principal
shareholder or related interest, and reduces deposit insurance coverage for
deposits offered by undercapitalized institutions for deposits by certain
employee benefits accounts.

     In addition to the statutory limitations, FDICIA originally required the
federal banking agencies to prescribe, by regulation, standards for all insured
depository institutions for such things as classified loans and asset growth. In
1994 FDICIA was amended to (a) authorize the agencies to establish safety and
soundness standards by regulation or by guideline for all insured depository
institutions; (b) give the agencies greater flexibility in prescribing asset
quality and earnings standards and (c) eliminate the requirement that such
standards apply to depository institution holding companies.

     On July 10, 1995 the federal banking agencies published Interagency
Guidelines Establishing Standards for Safety and Soundness. By adopting the
standards as guidelines, the agencies retained the authority to require an
institution to submit to an acceptable compliance plan as well as the
flexibility to pursue other more appropriate or effective courses of action
given the specific circumstances and severity of an institution's noncompliance
with one or more standards.

                                                                              25
<PAGE>
 
RESTRICTIONS ON DIVIDENDS AND OTHER DISTRIBUTIONS

     The power of the board of directors of an insured depository institution to
declare a cash dividend or other distribution with respect to capital is subject
to statutory and regulatory restrictions which limit the amount available for
such distribution depending upon the earnings, financial condition and cash
needs of the institution, as well as general business conditions. FDICIA
prohibits insured depository institutions from paying management fees to any
controlling persons or, with certain limited exceptions, making capital
distributions, including dividends, if, after such transaction, the institution
would be undercapitalized.

     Regulators also have authority to prohibit a depository institution from
engaging in business practices which are considered to be unsafe or unsound,
possibly including payment of dividends or other payments under certain
circumstances even if such payments are not expressly prohibited by statute.

     The payment of dividends by a national bank is further restricted by
additional provisions of federal law, which prohibit a national bank from
declaring a dividend on its shares of common stock unless its surplus fund
exceeds the amount of its common capital (total outstanding common shares times
the par value per share). Additionally, if losses have at any time been
sustained equal to or exceeding a bank's undivided profits then on hand, no
dividend shall be paid. Moreover, even if a bank's surplus exceeded its common
capital and its undivided profits exceed its losses, the approval of the OCC is
required for the payment of dividends if the total of all dividends declared by
a national bank in any calendar year would exceed the total of its net profits
of that year combined with its retained net profits of the two preceding years,
less any required transfers to surplus or a fund for the retirement of any
preferred stock. A national bank must consider other business factors in
determining the payment of dividends. The payment of dividends by the Bank is
governed by the Bank's ability to maintain minimum required capital levels and
an adequate allowance for loan losses. Regulators also have authority to
prohibit a depository institution from engaging in business practices which are
considered to be unsafe or unsound, possibly including payment of dividends or
other payments under certain circumstances even if such payment are not
expressly prohibited by statute.

PREMIUMS FOR DEPOSIT INSURANCE AND ASSESSMENTS FOR EXAMINATIONS

     FDICIA established several mechanisms to increase funds to protect deposits
insured by the Bank Insurance Fund ("BIF") administered by the FDIC. The FDIC
also administers the Savings Association Insurance Fund ("SAIF"), which insures
deposits in thrift institutions. The FDIC is authorized to borrow up to $30
billion from the United States Treasury; up to 90% of the fair market value of
assets of institutions acquired by the FDIC as receiver from the Federal
Financing Bank; and from depository institutions that are members of the BIF.
Any borrowings not repaid by asset sales are to be repaid through insurance
premiums assessed to member institutions. Such premiums must be sufficient to
repay any borrowed funds within 15 years and provide insurance fund reserves of
$1.25 for each $100 of insured deposits. FDICIA also provides authority for
special assessments against insured deposits. No assurance can be given at this
time as to what the future level of premiums will be.

                                                                              26
<PAGE>
 
     As required by FDICIA, the FDIC adopted a transitional risk-based
assessment system for deposit insurance premiums which became effective January
1, 1993. On November 14, 1995 the Board of Directors of the FDIC adopted a
resolution to reduce to a range of 0 to 27 basis points the assessment rates
applicable to deposits assessable by the BIF for the semiannual assessment
period beginning January 1, 1996. The new assessment schedule would retain the
risk based characteristics of the current system. On November 26, 1996 the FDIC
decided to continue in effect the current BIF assessment rate schedule.

     The FDIC may make limited adjustments to the above rate schedule not to
exceed an increase or decrease of 5 basis points without public notice and
comment rulemaking. The amount of an adjustment adopted by the Board is to be
determined by the following considerations: (a) the amount of assessment revenue
necessary to maintain the reserve ratio at the designated reserve ratio and (b)
the assessment schedule that would generate such amount of assessment revenue
considering the risk profile of BIF members. In determining the relevant amount
of assessment revenue, the Board is to consider BIF's expected operating
expenses, case resolution expenditures and income, the effect of assessments on
BIF members' earnings and capital, and any other factors the Board may deem
appropriate.

     In 1996 Congress enacted the Deposit Insurance Funds Act ("Funds Act") in
order to raise the level of SAIF reserves, and to reduce the possibility that
bonds issued by the Financing Corporation ("FICO") would go into default. The
FICO was a special purpose government corporation that issued $8.2 billion in
bonds to recapitalize the Federal Savings and Loan Insurance Corporation.
Interest on the FICO bonds was paid from the proceeds of assessment made on the
deposits of SAIF members. Because of the almost $800 million needed to pay for
the annual interest on the FICO bonds, the payments of SAIF members were not
increasing the SAIF reserve to a sufficient level to allow the FDIC to reduce
assessment rates (as had been done for BIF deposits), and SAIF members were
employing certain strategies to either exit the system or transfer deposits to
BIF coverage.

     Pursuant to the Funds Act, the FDIC imposed a special one-time assessment
on all institutions that held SAIF assessable deposits as of March 31, 1995 of
an estimated 65.7 cents per $100 of SAIF assessable deposits. Certain discounts
and exemptions from the assessment were available. For example, BIF-member banks
that had acquired SAIF-insured deposits from thrifts were generally entitled to
a 20% discount on the special assessment if the bank satisfied certain statutory
thresholds (the bank's acquired SAIF deposits, as adjusted, must be less than
half of its total domestic deposits). Furthermore, beginning January 1, 1997,
all FDIC-insured institutions will be assessed to cover the interest payments
due on FICO bonds. For calendar years 1997 through 1999, BIF members will pay
one-fifth the rate SAIF members will pay, and beginning in 2000 both types of
institutions will pay the same rate. BIF members will be required to pay a FICO
assessment of approximately 1.3 basis points for the first semiannual FICO
assessment in 1997.

                                                                              27
<PAGE>
 
      The Funds Act also authorized the FDIC to rebate assessments paid by BIF
members if the BIF has reserves exceeding its designated reserve ratio of 1.25
percent of total estimated insured deposits. The adjusted BIF balance was
$25.888 billion on June 30, 1996, a reserve ratio of 1.30 percent. The FDIC has
expressed its view that the long-term needs of the BIF are a factor in setting
the effective average BIF assessment rate, and that the FDIC is uncertain
whether the current favorable conditions represent a long-term trend.


COMMUNITY REINVESTMENT ACT AND FAIR LENDING DEVELOPMENTS

     The Bank is subject to certain fair lending requirements and reporting
obligations involving home mortgage lending operations and Community
Reinvestment Act ("CRA") activities. The CRA generally requires the federal
banking agencies to evaluate the record of a financial institution in meeting
the credit needs of their local communities, including low and moderate income
neighborhoods. In addition to substantive penalties and corrective measures that
may be required for a violation of certain fair lending laws, the federal
banking agencies may take compliance with such laws and CRA into account when
regulating and supervising other activities.

     On March 8, 1994, the federal Interagency Task Force on Fair Lending issued
a policy statement on discrimination in lending. The policy statement describes
the three methods that federal agencies will use to prove discrimination: overt
evidence of discrimination, evidence of disparate treatment, and evidence of
disparate impact.

     In 1996, new compliance and examination guidelines for the CRA were
promulgated by each of the federal banking regulatory agencies, fully replacing
the prior rules and regulatory expectations with new ones ostensibly more
performance based than before to be fully phased in as of July 1, 1997. The
guidelines provide for streamlined examinations of smaller institutions.


RECENTLY ENACTED LEGISLATION

     On September 29, 1995 the IBBA became effective. The IBBA implemented the
federal Interstate Banking and Branching Act. The main features of this
legislation are (a) out-of-state banks that wish to establish a California
branch office to conduct core banking business must first acquire an existing 5
year old California bank or industrial loan company by merger or purchase; (b)
California state-chartered banks will be empowered to conduct various authorized
branch-like activities on an agency basis through affiliated and unaffiliated
insured depository institutions in California and other states and (c) the
Superintendent will be authorized to approve an interstate acquisition or merger
which would result in a deposit concentration exceeding 30% if the
Superintendent finds that the transaction is consistent with public convenience
and advantage. The legislation also contains extensive provisions governing
intrastate and interstate (a) intra-industry sales, mergers and conversions
between banks and between industrial loan companies and (b) inter-industry
transactions involving banks, savings associations and industrial loan
companies.

                                                                              28
<PAGE>
 
     During 1996, new federal legislation amended the Comprehensive
Environmental Response, Compensation, and Liability Act ("CERCLA") and the
underground storage tank provisions of the Resource Conversation and Recovery
Act ("RCRA") to provide lenders and fiduciaries with greater protections from
environmental liability. The definition of "owner or operator" under CERCLA has
been amended to exclude a lender who: (i) holds indicia of ownership in a
property primarily to protect its security interest, but does not participate in
the property's management or (i) forecloses on a property, or, after
foreclosure, sells, re-leases (in the case of a lease finance transaction), or
liquidates the property, maintains business activities, winds up operations,
undertakes a response under CERCLA, or takes measures to preserve, protect or
prepare property prior to sale or disposition, so long as the lender did not
participate in the property's management prior to sale. In order to preserve
these protections, a lender who forecloses on property must seek to sell, re-
lease, or otherwise divest itself of the property at the earliest practicable,
commercially reasonable time, and on reasonable terms. "Participation in
management" is defined as actual participation in the management or operational
affairs of the facility, not merely having the capacity to influence or the
unexercised right to control operations. Similar changes have been made in RCRA.

     The California legislature adopted a similar bill to provide that, subject
to numerous exceptions, a lender acting in the capacity of a lender shall not be
liable under any state or local statute, regulation or ordinance, other than the
California Hazardous Waste Control Law, to undertake a cleanup, pay damages,
penalties or fines, or forfeit property as a result of the release of hazardous
materials at or from the property. Under this bill a lender which had not
participated in the management of the property prior to foreclosure may take
actions similar to those set forth in the CERCLA and RCRA amendments without
losing its immunity from liability. To preserve that immunity, after
foreclosure, the lender must take commercially reasonable steps to divest itself
of the property in a reasonably expeditious manner.


PENDING LEGISLATION

     There are a number of pending legislative proposals to reform the Glass-
Steagall Act to allow affiliations between banks and other firms engaged in
"financial activities," including insurance companies and securities firms.
Glass-Steagall reform will likely be affected by a bank insurance powers case
decided during 1996 by the U.S. Supreme Court, which gives national banks
greater opportunities to sell traditional insurance products, such as life,
automobile, and property and casualty policies. In a similar recent case, the
Court upheld an OCC determination that national banks may sell annuities.

     Certain other pending legislative proposals include bills to free
withdrawals from individual retirement accounts from penalties for first-time
home purchases and other purposes and eliminate most Community Reinvestment Act
reporting requirements.

     While the effect of such proposed legislation and regulatory reform on the
business of financial institutions cannot be accurately predicted at this time,
it seems likely that a significant amount of consolidating in the banking
industry will continue to occur throughout the remainder of the decade.

                                                                              29

COMPETITION

    In the past, an independent bank's principal competitors for deposits and
loans have been other banks (particularly major banks), savings and loan
associations and credit unions. To a lesser extent, competition was also
provided by thrift and loans, mortgage brokerage companies and insurance
companies. Other institutions, such as brokerage houses, mutual fund companies,
credit card companies, and even retail establishments have offered new
investment vehicles which also compete with banks for deposit business. The
direction of federal legislation in recent years seems to favor competition
between different types of financial institutions and to foster new entrants
into the financial services market, and it is anticipated that this trend will
continue.

    The enactment of the Interstate Banking and Branching Act in 1994 as well
as the California Interstate Banking and Branching Act of 1995 will likely
increase competition within California. Regulatory reform, as well as other
changes in federal and California law will also affect competition. While the
impact of these changes, and of other proposed changes, cannot be predicted with
certainty, it is clear that the business of banking in California will remain
highly competitive.

CERTAIN ADDITIONAL BUSINESS RISKS

    The Company's business, financial condition and operating results can be
impacted by a number of factors, including but not limited to those set forth
below, any one of which could cause the Company's actual results to vary
materially from recent results or from the Company's anticipated future results.

    Shares of Company Common Stock eligible for future sale could have a
dilutive effect on the market for Company Common Stock and could adversely
affect the market price.  The Articles of Incorporation of the Company authorize
the issuance of 20,000,000 shares of common stock, and 1,000,000 shares of
preferred stock of which approximately 754,500 shares of common stock and no
shares of preferred stock were outstanding at December 31, 1996. As of December
31, 1996, outstanding options to purchase Common Stock were 164,800, and Common
Stock available for grants under the Company's stock option plans was 85,200
shares.

    The loan portfolio of the Company is dependent on real estate.  At December
31, 1996, real estate served as the principal source of collateral with respect
to approximately 70% of the Company's loan portfolio.  A worsening of current
economic conditions or rising interest rates could have an adverse effect on the
demand for new loans, the ability of borrowers to repay outstanding loans, the
value of real estate and other collateral securing loans and the value of the
available-for-sale investment portfolio, as well as the Company's financial
condition and results of operations in general and the market value for Company
Common Stock.  Acts of nature, including earthquakes and floods, which may cause
uninsured damage and other loss of value to real estate that secures these
loans, may also negatively impact the Company's financial condition.

                                                                              30

    The Company is subject to certain operations risk, including, but not
limited to, data processing system failures and errors and customer or employee
fraud.  The Company maintains a system of internal controls to mitigate against
such occurrences and maintains insurance coverage for such risks, but should
such an event occur that is not prevented or detected by the Company's internal
controls, uninsured or in excess of applicable insurance limits, it could have a
significant adverse impact on the Company's business, financial condition or
results of operations.


ITEM 2.  PROPERTIES.

    The Bank maintains its main offices on leased premises at 901 Main Street in
the Downtown part of Napa, California.  The Company opened this banking facility
in 1995. This property is a two story building with an adjacent paved ground
level parking lot.  The parking lot is approximately 10,860 square feet.  The
lease term runs from December 1, 1994 to November 30, 1999, with three five (5)
year renewal options.  The lease provides for inflationary increases in the
monthly rental amount during the renewal periods and also contains options to
purchase the facility at an agreed upon market value during certain defined
periods.  The base rent is $9,900.00 per month.  The base rent is subject to an
annual adjustment based on the Consumer Price Index beginning on the first day
of January of every year of the first option renewal term beginning in the year
2001.  The adjusted rental will not exceed an 8% increase over the adjusted
rental of the preceding year nor will the adjusted rental be less than the
original base rent.  Rent paid for the Downtown Napa Office was approximately
$119,000 during 1996. In addition, the Bank pays utilities, insurance and
maintenance relating to the branch.

    The Company purchased its Claremont branch building for $558,000 in cash,
including fees, on September 6, 1989.  The building, comprised of approximately
5,000 square feet, was remodeled so that it could be put into service as a full
service banking branch.  The cost of the remodeling, security systems and
necessary furniture and equipment was approximately $600,000.  This Office was
remodeled again in 1995 in order to accommodate the Bank's Electronic Data
Processing and Customer Service Departments.  The cost of this remodel was
approximately $50,000.

    The Company leases the Bank's approximately 2,400 square foot branch office
located at 1015 Adams Street in downtown St. Helena, California.  The lease term
ends in 1998, with two options to extend the term of the lease for five years
each.  Rent paid for the St. Helena office was approximately $61,000 during
1996.  In addition, the Bank pays utilities, insurance and maintenance relating
to the branch.


ITEM 3.  LEGAL PROCEEDINGS.

    As of December 31, 1996, neither the Company, the Bank nor the Leasing
Company was a party to, nor was any of their property the subject of, any
material pending legal proceedings, nor are any such proceedings known to be
contemplated by governmental authorities.  At the same date, the Bank was
involved as plaintiff in ordinary routine litigation incidental to its business.

                                                                              31

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

    No matter was submitted to a vote of security holders during the fourth
quarter of the fiscal year covered by this report through the solicitation of
proxies or otherwise.

                                                                              32

ITEM 5.  MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.

    The Company's Common Stock is not listed on any exchange or the National
Association of Securities Dealers' Automated Quotation System; however, there
has been limited trading in the Company's Common Stock which the company does
not believe necessarily represents an established public trading market.  To the
Company's knowledge, no broker-dealers handle transactions of the Company's
common stock.  The following table sets forth, for the fiscal quarters
indicated, the range of high and low sales prices, not including broker's
commissions, based upon known information as reported by management.  These
figures may not include private transactions.  Other than to this extent, there
is no established public trading market in the Company's Common Stock.

    Because the Company's Common Stock is not listed on any exchange, accurate
trading volumes are difficult to ascertain. All known trades for 1996 involved
purchases by the Company's Employee Stock Ownership Trust ("ESOT"). The ESOT
purchased 19,855 shares in 1996. The ESOT did not purchase any shares of common
stock in 1995.

    As of February 28, 1997, the outstanding shares of the Company's Common
Stock were held of record by 353 shareholders.  The last known trade of the
Company's Common Stock occurred on December 11, 1996, for 100 shares.  Price per
share was $14.50.

                                                                              33
<PAGE>
 
    During the third quarter of 1996, the Company's ESOT sent out a tender offer
to purchase up to 20,000 shares of the Company's Common Stock.  The price of the
offer was set at $14.50 per share.  From this offer, the ESOT purchased 19,354
shares of the Company's outstanding Common Stock.

     During the first quarter of 1996, the Company declared and paid a cash
dividend of twelve and a half cents ($0.125) per share on outstanding stock. The
first quarter dividend was based on 1995 earnings and amounted to $94,000.
During the beginning of the second quarter of 1996, the Company declared a
second cash dividend of twelve and a half cents ($0.125) per share.  This cash
dividend was based on the first quarter earnings of 1996 and was also $94,000.
During the third quarter of 1996, the Bank paid a $100,000 cash dividend to the
Company.  This dividend allowed the Company to declare and pay another cash
dividend of twelve and a half cents ($0.125) per share for a total of $94,000.
In the fourth quarter of 1996, the Bank paid another $100,000 cash dividend to
the Company, allowing it to again declared and issue a twelve and a half cents
($0.125) per share dividend.  This fourth quarter dividend was based on third
quarter earnings and was paid to shareholders on January 3, 1997.  Total
dividends paid by the Bank to the Company and from the Company to its
shareholders for 1996 amounted to $200,000 and $378,000 respectively.

                                                                              34

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

    The following analysis of the Company's financial condition for the years
ended December 31, 1996 and 1995 and results of operation for each of the three
years in the period ended December 31, 1996, should be read in conjunction with
the Consolidated Financial Statements, related Notes thereto and other
information presented elsewhere herein.  Since the Company is a bank holding
company whose principal asset is, and is expected to be, the capital stock of
the Bank, the following relates principally to the financial condition and
results of operations of the Bank.

    The consolidated financial statements of the Company are prepared in
conformity with generally accepted accounting principles and prevailing
practices within the banking industry.  All material intercompany transactions
and accounts have been eliminated.  The preparation of financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
Average balances, including such balances used in calculating certain financial
ratios, are comprised of average daily balances.  All dollar amounts are
rounded, except earnings per share data.

    Certain statements in this Annual Report on Form 10-K include forward-
looking information within the meaning of Section 27A of the Securities Act of
1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as
amended, and are subject to the "safe harbor" created by those sections.  These
forward-looking statements involve certain risks and uncertainties that could
cause actual results to differ materially from those in the forward-looking
statements.  Such risks and uncertainties include, but are not limited to, the
following factors: competitive pressure in the banking industry increases
significantly; changes in the interest rate environment reduce margins; general
economic conditions, either nationally or regionally, are less favorable than
expected, resulting in, among other things, a deterioration in credit quality
and an increase in the provision for possible loan losses; changes in the
regulatory environment; changes in business conditions, particularly in Napa
County and the wine industry; volatility of rate sensitive deposits; operational
risks including data processing system failures or fraud; asset/liability
matching risks and liquidity risks; and changes in the securities markets.  See
also "Certain Additional Business Risks" included in Item 1 herein and other
risk factors discussed elsewhere in this Report.


SUMMARY OF FINANCIAL RESULTS

    The Company recorded net income of $902,000, or $1.00 per share for the year
ended December 31, 1996 compared to $1,101,000 or $1.25 per share, and $777,000
or $1.03 per share, for the year ended December 31, 1995 and 1994, respectively.

                                                                              36
<PAGE>
 
    Net income declined in 1996 over 1995 by $199,000, or 18%.  The primary
reasons for this decline were due to an increase in the provision for loan
losses of $227,000, or 70%, and increases in noninterest expenses of $690,000,
or 16%.  These increases were partially offset by an increase in net interest
income of $561,000, or 10%, and decreases in taxes of $151,000, or 20%.

    The primary reasons for the improvement in operating results in 1995 as
compared to 1994 are as follows:  Net interest income increased by $1,230,000 or
27%.  This growth was partially offset by an increase in the provision for loan
losses of $174,000 or 116%.  Total noninterest income increased by $173,000 or
28%.  These improvements were also offset by an increase in total noninterest
expense of $693,000 or 19%.

    Management is not aware of any trends, events or uncertainties that would
have a material impact on the Company's liquidity, capital resources, or results
of operations other than the early payoff of a purchased loan in January 1997
that resulted in a write off of $104,000 in unamortized premium.  The loan was
for commercial property in the Bank's service area that totalled approximately
$1,752,000 at the time of payoff.


NET INTEREST INCOME

    The Company's primary source of income is the difference between interest
income and fees derived from earning assets and interest paid on liabilities
incurred for the funding of those assets.  This difference is referred to as
"net interest income."  Net interest income expressed as a percentage of average
total earning assets is referred to as the "net interest margin" or "margin."

    For the period ended December 31, 1996, net interest income increased by
$561,000, or 10%, over the same period of 1995.  This number is a component of
total interest income and total interest expense.  The $11,085,000 increase in
average earning assets in 1996 compared to 1995 contributed significantly to
this increase in net interest income.  Even though average earning assets
increased significantly in 1996 over 1995, net interest income did not increase
as dramatically due to a decline in the Bank's net interest margin from 6.98%
for 1995 compared to 6.75% for 1996.

    Net interest income increased in 1995 by $1,230,000, or 27%, over 1994.
Total interest income increased in 1995 by $2,206,000, or 35%, over 1994.  This
increase was offset by an increase in total interest expense of $976,000, or
59%.  These results can be attributed to a number of factors, such as an
increase in the net interest margin from 6.25% in 1994 to 6.98% in 1995 (based
on period end earning assets).  This rise in net interest margin was aided by
increases in the prime interest rate during late 1994 and early 1995.
Additionally, average earning assets increased by $10,056,000 or 14%, in 1995
over 1994 totals.

    As of December 31, 1996, total average earning assets were $94,205,000, an
increase of $11,085,000, or 13%, from the 1995 level of $83,120,000.

                                                                              37
<PAGE>
 
PROVISION FOR LOAN LOSSES

    The provision for loan losses is based upon management's assessment of the
amount that is necessary to maintain the allowance for loan losses at an
adequate level.  As further described in the "Allowance for Loan Losses" herein,
management takes many factors into consideration when determining the provision
including loan portfolio growth.

     The provision for loan losses was $550,000 at December 31, 1996 compared to
$323,000 for 1995.  This represents an increase of $227,000, or 70%, over the
prior year.  The increase in the provision was due to increases in both average
loans and outstanding loan balances in 1996 over 1995 totals, projected loan
growth, increases in non-performing loans, and management's ongoing assessment
of the adequacy of the allowance for loan losses (See "Loans and Nonaccrual
Loans" herein).

    During 1995, the provision for loan losses was $323,000 as compared to
$149,000 for 1994.  As of December 31, 1995, total net loans were $73,374,000
compared to $62,103,000 for the same period in 1994.  This was an increase of
$11,271,000, or 18% over the prior year.


NONINTEREST INCOME

    Noninterest income consists primarily of service charges on deposit
accounts, fees charged for other banking deposit and loan services, and merchant
card processing income.  Noninterest income remained relatively flat between
1996 and 1995, showing only a $6,000, or 1%, growth over the prior year.
Service charges generated from deposit accounts continued to show growth due to
both increases in the number of outstanding accounts and a continued emphasis on
assessing service charges and other related fees. Additionally, the Bank's
merchant card processing program continued to show gains in 1996 over earnings
in 1995

    Noninterest income increased in 1995 by $173,000, or 28%, over 1994 totals,
primarily due to growth in deposit accounts and the related increase in service
charge income, and a more aggressive policy of assessing service charges and
other related fees.  Additionally, the Bank's merchant card processing program
was enhanced and expanded in early 1995 and showed a significant increase in
earnings during 1995 over 1994 totals.


NONINTEREST EXPENSE

    Total noninterest expense was $5,099,000 in 1996, representing an increase
of $690,000, or 16%, over the 1995 total of $4,409,000.  Total noninterest
expense in 1995 was $693,000, or 19%, above 1994's total of $3,716,000.

    Net salaries and employee benefit expense was $2,722,000 in 1996, an
increase of $461,000, or 20%, over 1995's total of $2,261,000.  During 1996, the
Bank grew by approximately five full time equivalent employees, two of which
were senior officers. Additionally, salaries increased due to average bank-wide
raises of approximately four percent which took place in March 1996.  The
Company did not accrue for incentive payouts in 1996 nor does it have plans on
paying any bonuses for performance in said year.

                                                                              38
<PAGE>
 
    Salaries and employee benefits were $2,261,000 in 1995, an increase of
$297,000, or 15%, over 1994.  This increase can be primarily attributed to an
addition of approximately five full time equivalent employees during 1995.
These staff increases were necessary to maintain an adequate service level given
the overall growth within the company.  Additionally, salaries also increased as
a result of average bank-wide raises of five percent which took place in March
1995.

    Occupancy and furniture, fixtures and equipment expenses increased in 1996
by $107,000, or 14% over 1995 totals.  This increase was due primarily to the
Bank's branch/headquarters tenant improvements (see discussion below) and
upgrades in electronic media throughout the Company.

    During April 1995, the Bank closed its original banking office located at
1500 Third Street, Napa, California and re-opened at 901 Main Street, Napa,
California.  At the end of June, the Bank relocated it primary lending services
and headquarters into the completed facility.  After relocation of the lending
and administration staff from its previous location at 3263 Claremont Way, Napa,
California, this facility began remodeling to accommodate the Bank's customer
service and EDP departments.  The remodeling of the Claremont facility was
completed in July and these two departments were immediately relocated.  With
the completion of this move, the Bank was able to vacate the leased space which
previously housed the Customer Service Center.  At the end of the third quarter
of 1995, the Bank had consolidated back into three locations, all offering full
banking services.  Occupancy and furniture, fixtures and equipment expenses for
the twelve months ending December 31, 1995 increased by $164,000 or 27%, over
the same period of 1994. These increases in costs were attributed primarily to
the Bank's new branch/headquarters tenant improvements, and the costs of
supporting its other locations.

    Professional fees increased in 1996 by $32,000, or 8%, over 1995 totals.
This increase was due primarily to the additional use of outside consultants for
both loan related legal reviews and audits and managerial issues.

    In 1995, professional and director fees increased by $241,000, or 137%, over
1994. This additional expense is primarily due to increases in consulting, legal
and director fees. Beginning in January 1995, the Company approved a new
director compensation plan which resulted in an increase of $63,000 over the
prior year. Consulting fees increased in 1995 by $34,000, due to the outsourcing
of a number of loan related reviews, audits and other similar procedures. The
Company incurred additional legal expenses of $52,000 in 1995 over the same
period of 1994.

    The competition for deposits and loans in the Company's service area
warranted increased marketing and business development expenditures during 1996.
Early in 1996, the Company hired an employee whose primary focus was marketing
and sales support.  This was done as a strategic move to enhance the Company's
overall marketing materials and focus both within the branches and in the
Company's service area.  This focus resulted in an increase of $46,000, or 37%,
in marketing expenses between 1996 and 1995.

                                                                              39
<PAGE>
 
    The Company decreased its marketing and business development costs by
$11,000, or 8%, during 1995 over the same period of 1994.  This decrease was
primarily due to the high profile marketing efforts incurred during the first
quarter of 1995.  Given the growth in loans and deposits resulting from these
marketing efforts, management curtailed the Bank's marketing costs greatly
during the remaining three quarters of 1995.

    Regulatory fees and related expenses decreased in 1996 by $70,000, or 34%,
over the same period of 1995.  The decrease was primarily due to changes in the
annual Federal Deposit Insurance Corporation assessments that occurred in the
latter half of 1995.  This same change also contributed to the drop in expense
in 1995 over 1994 totals.

    Stationery and supply expense for 1996 was $21,000, or 22%, higher than
1995.  This increase was due to general growth in the Company and the enhanced
marketing oriented materials used within the branches.  In 1995, stationery and
supply expense was $95,000, or 42%, higher than 1994.  The increase in 1995 was
due to significant one time expenses related to the numerous facility moves and
relocations which incurred during 1995.

    Data processing expenses have shown a steady increase during the three years
presented and have been in keeping with the overall growth of the Company.
Additionally, the $16,000, or 15%, growth in 1996 over 1995 was also due to
enhancements and upgrades made to the Company's personal computers.

    Other noninterest expense increased by $77,000, or 19%, in 1996 over 1995
totals.  The increase was due primarily to increase in miscellaneous loan
expenses and staff training and development.  The increase between 1995 and 1994
was in keeping with the general growth of the Company.


INCOME TAXES

    Income tax expense was 41% and 42% of pre-tax income for the years ending
December 31, 1996 and 1995, respectively.


EARNING ASSETS

    Total earning assets consist of investment securities, loans, federal funds
sold and interest bearing deposits held in other institutions. Total earning
assets increased from $95,267,000 at December 31, 1995 to $102,680,000 at
December 31, 1996, an increase of $7,413,000, or 8%.


LOANS AND NONACCRUAL LOANS

    Total loans, excluding the allowance for loan losses (see Notes 1 and 4 to
the Consolidated Financial Statements included herein at Item 14, for further
discussion of the allowance for loan losses), increased from $74,699,000 at
December 31, 1995 to $79,695,000 at December 31, 1996.  The increase of
$4,996,000 represents a 7% increase in outstanding loans during 1996.  The Bank
experienced increases in all of its loan categories except for a slight decline
in personal line of credit loans during the year under review.  Management
attributes these increases to more seasoned staff, both loan and deposit
officers, which assisted with new loan generation and changes taking place in
the Company's service area.

                                                                              40

    General economic and credit risks are inherent in the lending function and
within particular types of lending categories.  The Bank primarily makes four
types of loans:  Real estate construction, real estate mortgage, commercial and
consumer loans.  As discussed in "Item 1. Business - Loan Portfolio" herein, the
Bank generally takes a collateralized position, with reasonable loan to value
ratios on its loans (over 90% of the Bank's loan portfolio is collateralized).
The primary source of collateral is real estate located within the Company's
service area.  An inherent risk in taking real estate as collateral is the
possibility of declines in real estate market values.

    The Company's service area is Napa Valley, which is located approximately
fifty miles northeast of the San Francisco Bay Area.  Napa Valley is a very
unique, and rather isolated area that has been able to sustain higher than
average real estate market values.  Approximately four years ago, given the
economic trends and possibility of declining market values, the Company took a
more conservative approach on its collateral base and began lowering its loan to
value ratios on new loans.  Even though the Company's loan portfolio is heavily
secured by California real estate, management does not presently foresee any
material impact on the Company's operations, given the low loan to value ratios.

    As of December 31, 1996, nonperforming loans were $3,152,000, an increase of
$1,705,000, or 118%, over the December 31, 1995 balance of $1,447,000.
Nonperforming loans at December 31, 1996 represent 4.0% of total average loans
compared to 2.1% of total average loans for year end 1995.  The growth in
nonperforming loans between 1996 and 1995 is primarily due to a rise in
bankruptcies in 1996 compared to 1995, and to the general growth in outstanding
loan balances.  The increase in nonperforming loans, in management's opinion,
does not represent a material trend.

    As discussed in "Item 1 - Business, Loan Portfolio", in early 1997, the
Company's service area was subjected to severe weather conditions that resulted
in some flooding.  Management believes that this flooding will not have a direct
or material impact on either its existing loan portfolio or future growth.

                                                                              41
<PAGE>
 
    On January 1, 1995, the Company adopted SFAS No. 114, "Accounting by
Creditors for Impairment of a Loan" and SFAS No. 118, "Accounting by Creditors
for Impairment of a Loan - Income Recognition and Disclosure". These statements
address the accounting and reporting by creditors for impairment of certain
loans. A loan is impaired when, based upon current information and events, it is
probable that a creditor will be unable to collect all amounts due according to
the contractual terms of the loan agreement. These statements are applicable to
all loans, uncollateralized as well as collateralized, except large groups of
smaller-balance homogeneous loans that are collectively evaluated for impairment
such as credit cards, residential mortgage and consumer installment loans, loans
that are measured at fair value or at the lower of cost or fair value and
leases. Impairment is measured based on the present value of expected future
cash flows discounted at the loan's effective interest rate, except that as a
practical expedient, the Company measures impairment based on a loan's
observable market price or the fair value of the collateral if the loan is
collateral dependent. Loans are measured for impairment as part of the Company's
normal internal asset review process.

    Interest income is recognized on impaired loans in a manner similar to that
of all loans.  It is the Company's policy to place loans that are delinquent 90
days or more as to principal or interest on a nonaccrual of interest basis
unless secured and in the process of collection, and to reverse from current
income accrued but uncollected interest.  Cash payments subsequently received on
nonaccrual loans are recognized as income only where the future collection of
principal is considered by management to be probable.

    At December 31, 1996, the Company's total recorded investment in impaired
loans was $3,152,000, of which there is a related allowance for credit losses of
$204,000.

    The average recorded investment in the impaired loans during 1996 was
$2,123,000: the related amount of interest income recognized during the period
that such loans were impaired recognized under the cash basis method of
accounting was $44,000.

    Loans currently classified as special mention, substandard, doubtful or loss
(See Item 1, "Business" herein) do not, in management's view, represent or
result from trends or uncertainties which may have a material adverse effect on
the entire loan portfolio, liquidity or capital resources.


ALLOWANCE FOR LOAN LOSSES

    Inherent in the lending function is the fact that loan losses will be
experienced and that the risk of loss will vary with the type of loan being made
and the credit - worthiness of the borrower over the term of the loan. The
Company maintains an allowance for possible loan losses at a level estimated to
be adequate to provide for losses that can be reasonably anticipated based upon
specific loan conditions as determined by management, and based upon
management's assessment of historical loan loss experience, prevailing economic
conditions and other factors including growth of the loan portfolio.  While
these factors are essentially judgmental and may not be reduced to a
mathematical formula, it is management's view that the $1,405,000 allowance,
approximately 1.76% of total loans outstanding at December 31, 1996, was
adequate as an allowance against foreseeable losses in the portfolio at that
time.  The allowance was 1.77% of the loan portfolio at 

                                                                              42
<PAGE>
 
December 31, 1995. The allowance is increased by charges to the provision for
loan losses and reduced by net charge-offs.


OTHER REAL ESTATE OWNED

    At December 31, 1996 and December 31, 1995, total other real estate owned
was $328,000 and $0, respectively, which at December 31, 1996 consisted of two
separate properties.


DEPOSITS

    Deposits totaled $105,417,000 at December 31, 1996, an increase of
$8,665,000, or 9%, from the December 31, 1995 balance of $96,752,000.  In 1996,
noninterest bearing transaction accounts grew by $6,660,000, or 35%, savings
accounts decreased by $340,000, or 3%, and interest bearing transaction accounts
grew $1,257,000, or 4%, over 1995 totals.  Time certificates of deposit of
$100,000 or more increased by $1,293,000, or 14%, and other time deposits
decreased by $205,000, or 1%, during 1996.  The overall growth in deposit
accounts in 1996 was primarily due to a comprehensive marketing effort on the
part of the Bank's staff and management, the introduction of new and enhanced
deposit products and increases in deposit officers.

    Non-interest bearing demand deposits were 24% of total deposits at December
31, 1996, as compared to 20% at December 31, 1995.  Time certificates of deposit
were 36% of total deposits at December 31, 1996, and 39% for the same period of
1995.


NEW ACCOUNTING PRONOUNCEMENTS

    Effective January 1, 1996, the Company adopted SFAS No. 123, "Accounting for
Stock-Based Compensation", which establishes financial and reporting standards
for stock-based compensation plans.  The Company elected to continue accounting
for stock-based employee compensation plans in accordance with APB Opinion No.
25, "Accounting for Stock Issued to Employees" and related interpretations, as
SFAS 123 permits, and to follow the pro forma net income, pro forma earnings per
share and stock-based compensation plan disclosure requirements set forth in
SFAS 123.

    In March 1995, the Financial Accounting Standards Board issued SFAS No. 121,
Accounting for Impairment of Long-Lived Assets and for Long-Lived Assets to Be
Disposed Of.  SFAS No. 121 is effective for fiscal years beginning after
December 15, 1995.  This Statement requires that long-lived assets and certain
identifiable intangibles to be held and used by an entity, be reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable.  The financial statement
impact of adopting SFAS No. 121 has not been material.

                                                                              43

ASSET-LIABILITY MANAGEMENT

    Asset-liability management is a process whereby the Bank, through its Asset
and Liability Committee, monitors the maturities and repricing opportunities of
the various components of the balance sheet and initiates strategies designed to
maximize the net interest margin, while minimizing vulnerability to large
fluctuations in interest rates.  The Bank is currently moving towards a policy
of maintaining a relative balance of asset and liability maturities within
similar time frames, while permitting a moderate amount of short-term interest
rate risk based on current interest rate projections, customers' credit demands
and deposit preferences.

    At December 31, 1996, the Company's assets repricing in one year exceeded
its liabilities repricing in one year by $21,612,000, or 19%, of total assets.
This compares to $15,348,000, or 15% of total assets in 1995. The excess of
assets repricing over liabilities repricing means that if interest rates
decline, the Company's return on assets would be expected to decline more
quickly than its cost of funds, thereby reducing the Company's net interest
margin.  However, as interest rates increase, the Company's return on assets
would be expected to increase more quickly than its cost of funds.

    The following table represents the interest rate sensitivity profile of the
Company's consolidated assets, liabilities and shareholders' equity as of
December 31, 1996.  Assets, liabilities and shareholders' equity are classified
by the earliest possible repricing opportunity or maturity date, whichever first
occurs.  Assumptions used in constructing the table include the following:  The
loans that are in the "Interest Rate Sensitivity Over One Year But Within 5
Years" and "Nonrate Sensitive or Over 5 Years" columns are all fixed-rate loans
and therefore mature in those time frames.  The Bank's certificates of deposits
are substantially all fixed-rate, therefore they are in the columns which
represent the time frames in which they mature.  All other interest-bearing
accounts reprice overnight and are therefore in the "Interest Rate Sensitivity
0-90 Days" column.  Included in noninterest bearing liabilities is $25,728,000
in demand deposit accounts.

                                                                              44

LIQUIDITY

    Liquidity refers to the Company's ability to maintain cash flow adequate to
fund operations and meet obligations and other commitments on a timely basis.
Management strives to maintain a level of liquidity sufficient to meet customer
requirements for loan funding and deposit withdrawals. Liquidity requirements
are evaluated by taking into consideration factors such as deposit
concentrations, seasonality and maturities, loan demand, capital expenditures,
and prevailing and anticipated economic conditions. As shown in the Consolidated
Statements of Cash Flows ("Statement") for the years ended December 31, 1996,
1995 and 1994, the Company's usual and primary source of funds has been customer
deposits and cash flow generated from operating activities.  While the usual and
primary sources are expected to continue to provide significant amounts of funds
in the future, their mix, as well as those from other sources, will depend on
future economic and other market conditions.

    In 1996, the Statement shows that operations and financing activities were
sources of net cash inflows ($510,000 and $8,287,000, respectively) for the
year.  These sources were significant enough to increase the overall ending cash
and cash equivalents from $21,886,000 at December 31, 1995 to $24,479,000 at
December 31, 1996, an increase of $2,593,000.

    In 1995, the Statement shows that operations and financing activities were
also sources of net cash inflows ($1,000,000 and $17,374,000, respectively) for
the year.  These sources increased ending cash and cash equivalents by
$5,667,000, taking the total from $16,219,000 at December 31, 1994 to
$21,886,000 at the end of 1995.

    In 1994, the Statement shows that operations and financing activities were
sources of net cash inflow ($1,247,000 and $7,915,000 respectively) for the
year.  These sources were the primary reason for the small decrease in ending
cash and cash equivalents from $17,284,000 at December 31, 1993 to $16,219,000
at the end of 1994.

    Liquidity is measure by various ratios, the most common being the liquidity
ratio of cash less reserves, time deposits with other financial institutions,
federal funds sold, and unpledged investment securities compared to total
deposits.  This ratio was 26% at both December 31, 1996 and December 31, 1995.

    Parent Company liquidity is maintained by cash flows stemming primarily
from dividends from the bank.  The amount of dividends from the Bank is subject
to certain regulatory restrictions as discussed in Note 12 of the Notes to
Consolidated Financial Statements.  The Parent Company financial statements are
presented in Note 16 of the Notes to Consolidated Financial Statements.

CAPITAL ADEQUACY

    The Federal Reserve Bank and the Comptroller of the Currency have specified
guidelines for the purpose of evaluating the capital adequacy of bank holding
companies and banks.  The table below summarizes the current requirements for
1996 and the Company's and the Bank's compliance therewith.

currently exceed the regulatory requirements for a "well capitalized"
institution.  Management anticipates that both the Company and the Bank will
continue to exceed the regulatory minimums in the foreseeable future. Therefore,
the Company and the Bank have adequate capital in order to expand in the future,
either through loan generation or other means of expansion.

    As of the date of this report, management is not aware of any trends, events
or uncertainties that will have, or are reasonable likely to have a material
effect on the Company's liquidity, capital resources, or results of operations.
Additionally, the Company is subject to no current recommendations by any
regulatory authorities which, if implemented, would have such an effect.


EFFECTS OF INFLATION

    The impact of inflation on a financial institution differs significantly
from that exerted on an industrial concern, primarily because its assets and
liabilities consist largely of monetary items.  The most direct effect of
inflation is higher interest rates.  However, the Bank's earnings are affected
by the spread between the yield on earning assets and rates paid on interest-
bearing liabilities rather than the absolute level of interest rates.
Additionally, there may be some upward pressure on the Company's operating
expenses, such as adjustments in staff expense and occupancy expense, based upon
consumer price indices.  In the opinion of management, inflation has not had a
material effect on the consolidated results of operations for the last three
years.

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

    In September 1996, the Company retained Ernst & Young LLP to be the
Company's auditors for the current year ending December 31, 1996.  The Company's
prior auditing firm was Deloitte & Touche LLP.  Deloitte & Touche LLP had
audited the Company's financial statements for the years ended December 31, 1988
through December 31, 1995.  Deloitte & Touche LLP were dismissed in September
1996.  The Company had no disagreements with Deloitte & Touche LLP on any matter
of accounting principles or practices, financial statement disclosure, or
auditing scope of procedures.  The accountant's reports on financial statements
for the past eight years did not contain an adverse opinion or a disclaimer of
opinion, nor were they qualified or modified as to uncertainty, audit scope, or
accounting principles. Registrant hereby incorporates by reference herein its
report on Form 8-K filed on September 26, 1996 and amended on October 23, 1996.

                         Report of Independent Auditors

To the Shareholders and Board of Directors of
 Napa National Bancorp

We have audited the accompanying consolidated balance sheet of Napa National
Bancorp and subsidiaries as of December 31, 1996, and the related consolidated
statements of income, changes in shareholders' equity and cash flows for the
year then ended.  These financial statements are the responsibility of the Napa
National Bancorp's management.  Our responsibility is to express an opinion on
these financial statements based on our audit.  The financial statements of Napa
National Bancorp for the years ended December 31, 1995 and 1994, were audited by
other auditors whose report dated March 22, 1996, expressed an unqualified
opinion on those statements.

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

In our opinion, the 1996 consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Napa National Bancorp and subsidiaries at December 31, 1996, and the
consolidated results of their operations and their cash flows for the year then
ended in conformity with generally accepted accounting principles.

To the Shareholders and

statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain

misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also 
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement 
presentation.  We believe that our audits provide a reasonable basis for our 
opinion.

In our opinion, such consolidated financial statements present fairly, in all 
material respects, the financial position of Napa National Bancorp and

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

Napa National Bancorp is a bank holding company whose primary investment is Napa
National Bank (the "Bank").  Napa National Bancorp's only other investment is in
a wholly owned inactive leasing subsidiary.  The Bank is a full service
community commercial bank with three offices in the Napa Valley area in Northern
California.  The Bank's primary source of revenue is from providing loans to
customers, who are predominantly individuals, professionals and small to medium
sized businesses.

PRINCIPLES OF CONSOLIDATION AND USE OF ESTIMATES IN PREPARATION OF FINANCIAL
STATEMENTS

The consolidated financial statements of Napa National Bancorp and subsidiaries
(the "Company") are prepared in conformity with generally accepted accounting
principles and prevailing practices within the banking industry.  All material
intercompany transactions and accounts have been eliminated.  The preparation of
financial statements in conformity with generally accepted accounting principles
requires management to make estimates and assumptions that affect the reported
amounts.  These estimates are based on information available as of the date of
the financial statements.  Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS

Cash and cash equivalents include cash on hand, amounts due from banks, and
federal funds sold.  Generally, federal funds sold are sold for one business
day.

INVESTMENT SECURITIES

Held-to-maturity securities are those securities which management has the
ability and intent to hold to maturity.  These securities are stated at cost,
adjusted for amortization of premiums and accretions of discounts to maturity
using methods approximating the interest method.  All of the Bank's investment
securities are classified as held-to-maturity.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

LOANS

Loans are stated at the principal amount outstanding and net of any deferred
loan origination fees or costs. Interest income on loans is accrued daily on a
simple interest basis.  The Bank places an asset on nonaccrual status when any
installment of principal or interest is 90 days past due, unless well secured
and in the process of collection, or when management determines that ultimate
collection of principal or interest on a loan is unlikely.  When a loan is
placed on nonaccrual, all previously accrued but uncollected interest is
reversed.  Cash payments subsequently received on nonaccrual loans are
recognized as income only where the collection of principal is considered by
management as probable.  Interest accruals are resumed on such loans only when
they are brought fully current with respect to interest and principal and when,
in the judgment of management, the loans are estimated to be fully collectible
as to both principal and interest.

ALLOWANCE FOR LOAN LOSSES

The allowance for loan losses is a reserve established through a provision for
loan losses which is charged to expense.  Losses are charged against the
allowance when management believes that the collectibility of the principal is
unlikely.  The allowance is maintained at an amount that management believes
will be adequate to absorb losses inherent in existing loans and commitments to
extend credit, based on evaluations of their collectibility and the Bank's prior
loss experience.  The evaluations take into consideration such factors as
changes in the nature and volume of the portfolio, overall portfolio quality,
loan concentrations, specific problem loans, and current economic conditions
that may affect the borrowers' ability to repay.

Effective January 1, 1995, the Company adopted Statement of Financial Accounting
Standards No. 114 (SFAS 114), "Accounting by Creditors for Impairment of a
Loan," as amended.  Under SFAS 114, a loan is impaired when it is "probable"
that a creditor will be unable to collect all amounts due according to the
contractual terms of the loan agreement.  SFAS 114 excludes large groups of
smaller balance homogeneous loans that are collectively evaluated for
impairment.  The Company has defined one to four  family loans and consumer
loans as homogeneous loans.  All homogeneous loans that are 90 days or more
delinquent or are in foreclosure are automatically placed on nonperforming
status. The adoption of SFAS 114 did not have a material effect on the Company's
financial condition or results of operations

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

PREMISES AND EQUIPMENT

Premises and equipment are carried at cost less accumulated depreciation and
amortization.  Depreciation and amortization expenses are computed using the
straight-line method over the shorter of estimated useful lives of the related
assets (which are generally three to twenty years) or the lease terms.
Maintenance and repair costs are expensed as incurred, whereas expenditures that
improve or extend the service lives of assets are capitalized.

OTHER REAL ESTATE OWNED

Other real estate owned ("OREO"), which is recorded in other assets, includes
properties acquired through foreclosure or in full or partial satisfaction of
the related loan.  OREO also includes loans where the Bank has obtained physical
possession of the related collateral.  OREO is carried at the lower of fair
value, net of estimated selling and disposal costs, or cost.  Fair value
adjustments are made at the time that real estate is acquired through
foreclosure or when full or partial satisfaction of the related loan is
received.  These fair value adjustments are treated as loan losses.

INCOME TAXES

The Company accounts for income taxes under the asset and liability method.
Deferred taxes arise from the effect of temporary differences between the tax
bases of assets and liabilities and their reported amounts in the financial
statements, and from the effect of operating loss carryforwards on taxes payable
in future years based on currently enacted tax law.  Deferred tax assets are
reduced by a valuation allowance if, based on available evidence, it is more
likely than not that some or all of the deferred tax assets will not be
realized.

STOCK-BASED COMPENSATION

Effective January 1, 1996, the Company adopted Statement of Financial Accounting
Standards No. 123 (SFAS 123), "Accounting for Stock-Based Compensation," which
establishes financial accounting and reporting standards for stock-based
compensation plans.  The Company elected to continue accounting for stock-based
employee compensation plans in accordance with Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued To Employees" and related
interpretations, as SFAS 123 permits, and to follow the pro forma net income,
pro forma earnings per share and stock-based compensation plan disclosure
requirements set forth in SFAS 123.

NET INCOME PER COMMON SHARE

Net income per common share is computed by dividing net income by the weighted
average number of common shares and dilutive stock options outstanding during
the year.

RECLASSIFICATION

Certain amounts in prior periods have been reclassified to conform to the 1996
presentation.

2. CASH AND DUE FROM BANKS

The Bank is required to maintain reserves with the Federal Reserve Bank.  The
average reserves required for 1996 and 1995 were $952 and $703, respectively.

4. LOANS AND ALLOWANCE FOR LOAN LOSSES

Loans are presented net of unearned income of $374 and $296 at December 31, 1996
and 1995, respectively. Nonaccrual loans past due 90 days or more as of December
31, 1996 and 1995, were approximately $3,152 and $1,447 respectively.  The
effect on interest income, had these loans been performing in accordance with
contractual terms as of December 31, 1996 and 1995, would have been an increase
of approximately $188 and $291, respectively.

At December 31, 1996, the Company had approximately $3,152 of loans considered
to be impaired in accordance with SFAS  114.  These loans were evaluated for
impairment primarily using the collateral method and required an allowance for
credit losses measured in accordance with SFAS  114 of $204 .  Average impaired
loans during the year ended December 31, 1995 amounted to approximately $2,123.
Related interest income recognized on impaired loans during the year ended
December 31, 1996 was approximately $44.

The activity in the allowance for loan losses for the years ended December 31,
1996, 1995 and 1994 is summarized as follows (in thousands):

At December 31, 1996 and 1995, the Bank was servicing loans for the Federal Home
Loan Mortgage Corporation with unpaid principal balances of $23,020 and $22,508,
respectively.  Servicing loans for others generally consists of collecting
mortgage payments, maintaining escrow accounts, disbursing payments to investors
and conducting foreclosures proceedings.  Loan servicing income is recorded on
the accrual basis and includes servicing fees from investors and certain charges
collected from borrowers, such as late payment fees.  Income from loan servicing
amounted to $62, $51 and $60 for the years ended December 31, 1996, 1995 and
1994, respectively.

7. INCOME TAXES (CONTINUED)

Deferred tax assets are recognized to the extent that their realization is more
likely than not.  As of December 31, 1996, 1995 and 1994, the Bank was unable to
conclude that the realization of the Company's deferred tax asset was more
likely than not.  Accordingly, a valuation allowance has been reflected at
December 31, 1996, 1995 and 1994 to reduce the Bank's deferred tax assets to the
amount likely to be realized.

The difference between the statutory federal income tax rate and the Company's
effective tax rate, expressed as a percentage of income before income taxes, is
as follows:

8. TRANSACTIONS WITH RELATED PARTIES

The Company has had, and expects to have in the future, banking transactions,
primarily loans, in the ordinary course of business with directors, executive
officers and their associates.  In accordance with Company policy, loans to
related parties are granted on the same terms, including interest rates and
collateral, as those prevailing at the same time for comparable transactions
with others, and do not involve more than the normal risk of collectibility.
Loans to related parties for the years ended December 31, 1996 and 1995, are as
follows:

8. TRANSACTIONS WITH RELATED PARTIES (CONTINUED)

The Company also had commitments to extend credit to related parties of $337 at
December 31, 1996.  Other activity in the table above represents loans to
directors or officers who left the Company during the year and are, therefore,
not considered related parties for purposes of this disclosure.  At December 31,
1996 and 1995, an affiliated company of a member of the Board of Directors had
$779 and $445 (0.7% and 0.5% of total deposits), respectively, deposited with
the Company.  These deposits were on the same terms as those prevailing at the
same time for comparable transactions with others.

9. FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

In the normal course of business, the Company is party to financial instruments
with off-balance sheet risk to meet the financing needs of its customers.  These
financial instruments include commitments to extend credit and standby letters
of credit.  The instruments involve, to varying degrees elements of credit and
interest rate risk in excess of the amount recognized in the consolidated
balance sheet.  The contract or notional amounts of those instruments reflect
the extent of involvement the Company has in particular classes of financial
instruments.

The Company's exposure to credit loss in the event of nonperformance by the
other party to the financial instrument for commitments to extend credit and
standby letters of credit written is represented by the contractual  amount of
these instruments.

At December 31, 1996, financial instruments whose contract amounts represent
credit risk were as follows:

9. FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK (CONTINUED)

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

Standby letters of credit are conditional commitments issued by the Company to
guarantee the performance of a customer to a third party.  The credit risk
involved in issuing standby letters of credit is essentially the same as that
involved in extending loans to customer.  At December 31, 1996, all standby
letters of credit were secured by normal business assets in accordance with the
Company's standard lending practices.

10. CONCENTRATION OF CREDIT RISK

The Company grants residential, commercial, construction, agricultural and
consumer loans to customers principally located in Napa County, California.
Although the Company has a diversified loan portfolio, a substantial portion of
its debtors' ability to honor their contracts is dependent on the economic
conditions of the wine industry.  At December 31, 1996, the Company's loans to
companies in the wine industry were $10,933 with commitments to lend an
additional $4,670.  The Company requires that loan customers meet the collateral
requirements described in Note 9 for commitments to extend credit.

As of December 31, 1996 and 1995, the Company's real estate loans were
collateralized primarily with real estate located in the Napa Valley area.  As
such, the ultimate collectibility of a substantial portion of the Company's loan
portfolio is influenced by the overall condition of the Northern California real
estate market.

11. COMMITMENTS AND CONTINGENCIES

The Company and the Bank lease a portion of their banking and office facilities
under noncancelable operating leases.  Total minimum future rental payments

Rental expense was $194, $201 and $155 for the years ended December 31, 1996,
1995 and 1994, respectively.

The Company is involved in various legal actions arising from normal business
activities.  Management believes that the ultimate resolution of these actions
will not have a material effect on the consolidated financial statements.

12. RESTRICTIONS ON RETAINED EARNINGS

Under the U.S. National Bank Act and other federal laws, the Bank is subject to
prohibitions on the payment of  dividends in certain circumstances and to
restrictions on the amount that it can pay without prior approval of the Office
of the Comptroller of the Currency.  Without the Comptroller's approval,
dividends for a given year cannot exceed the Bank's retained net income for that
year and retained net profits from the preceding two years.  In addition,
dividends may not be paid in excess of the Bank's undivided profits, subject to
other applicable provisions of law.  Based upon these restrictions, the Bank
could have declared dividends for 1996 of $2,609 without prior regulatory
approval.

13. REGULATORY MATTERS

Napa National Bancorp and the Bank are subject to various regulatory capital
requirements administered by the federal banking agencies.  Failure to meet
minimum capital requirements can initiate certain mandatory--and possibly
additional discretionary--actions by regulators that, if undertaken, could have
a direct material effect on the their financial statements.  Under capital
adequacy guidelines and the regulatory framework for prompt corrective action,
Napa National Bancorp and the Bank must meet specific capital guidelines that
involve quantitative measures of the thier assets, liabilities, and certain off-
balance-sheet items as calculated under regulatory accounting practices.
Capital amounts and classification are also subject to qualitative judgments by
the regulators about components, risk weightings, and other factors.

Quantitative measures established by regulation to ensure capital adequacy
require that minimum amounts and ratios (set forth in the table below) of total
and Tier I capital (as defined in the regulations) to risk-weighted assets (as
defined), and of Tier I capital (as defined) to average assets (as defined) be
maintained.  Management believes, as of December 31, 1996, that Napa National
Bancorp and the Bank meet all capital adequacy requirements.

As of December 31, 1996, the most recent notification from the Office of the
Comptroller of the Currency categorized both Napa National Bancorp and the Bank
as well capitalized under the regulatory framework for prompt corrective action.
To be categorized as well capitalized minimum total risk-based, Tier I risk-
based, and Tier I leverage ratios as set forth in the table below must be
maintained.  There are no conditions or events since that notification that
management believes have changed the institution's category.

14. STOCK OPTION PLAN AND STOCK OWNERSHIP PLAN

The Company has a stock option plan that provides for issuance of incentive
stock options (ISO) to certain officers and nonstatutory stock options to
certain members of the Company's Board of Directors to purchase up to 250,000
shares of common stock. Each option entitles the holder to purchase one share of
common stock. Outstanding options that expire at various dates through 2006 have
been granted at a price of $8.00 to $15.35. This price approximates the market
value of the stock at the dates the options were granted. The right to exercise
options vests either immediately or at various rates in each year of future
service. There were 85,200 options available for grant at December 31, 1996.
Option information is summarized below:

14. STOCK OPTION PLAN AND STOCK OWNERSHIP PLAN (CONTINUED)

The table below reflects the Company's net income and net income per common
share (under the Treasury Stock method), if compensation cost for the Company's
stock plan had been determined based on the fair value at the grant date for
awards under their plan.  Since pro forma compensation cost relates to all
periods over which the awards vest, the initial impact on pro forma net income
may not be representative of compensation cost in subsequent years.
<TABLE>
<CAPTION>
 
                                          1996    1995

Net income applicable to common stock     $ 866   $1,070
Net income per common share               $0.97   $ 1.20
</TABLE>

Fair values of the options were estimated at the date of grant using the Black-
Scholes option pricing model, which includes the following assumptions used for
the stock options awarded during 1996 and 1995, respectively:  risk-free
weighted average interest rates of 6.52 percent and 5.77 percent; dividend yield
of .16 percent and 0 percent; expected volatility of 5.6 percent and 1.9
percent; and expected option life for both 1996 and 1995 grants of 8.5 years.

The weighted average grant date fair values of the options granted during 1996
and 1995 were $6.57 and $7.76 per share, respectively.  The exercise price of
each option approximates the market price of the Company's common stock on the
date of grant.  Expiration dates range from September 16, 1998 to December 16,
2006 for options outstanding at December 31, 1996.

The Company also has an Employee Stock Ownership Trust (the "ESOT"), in which
all employees of the Company are eligible to participate.  The ESOT is a
defined-contribution plan which invests in the common stock of the Company.  A
portion of these contributions is matched by the Company.  The Company's
matching contributions to the ESOT were $74, $60 and $23 for the years ended
December 31, 1996, 1995 and 1994, respectively.

15. FAIR VALUE OF FINANCIAL INSTRUMENTS

The estimated fair values of financial instruments amounts have been determined
by using available market information and appropriate valuation methodologies.
However, these estimated fair values are subjective in nature and involve
uncertainties and matters of significant judgment and therefore cannot be
determined with precision.  Changes in the market assumptions or estimation
techniques could significantly affect the fair value estimates.  Because of the
limitations, the aggregate fair value amounts presented below are not
necessarily indicative of the amounts that could be realized in a current market
exchange.

The carrying amounts and the estimated fair values of the Company financial
instruments at December 31, 1996 are as follows:

</TABLE>

(a) Cash and cash equivalents:  The carrying amount is a reasonable estimate of
    fair value.

(b) Interest-bearing time deposits - other financial institutions:  The carrying
    value is a reasonable estimate of fair value.

(c) Securities held to maturity:  Fair values of investment securities are based
    on quoted market prices or dealer quotes.  If a quoted market price was not
    available, fair value was estimated using quoted market prices for similar
    securities.

(d) Loans - net:  Fair values for certain commercial construction, revolving
    consumer credit and other loans were estimated by discounting the future
    cash flows using current rates at which similar loans would be made to
    borrowers with similar credit ratings and maturities.  Certain adjustable
    rate loans and leases have been valued at their carrying values, since the
    interest rate adjustment characteristics of the loan or lease effectively
    adjust the interest rate to maintain a market rate of return.

15. FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)

(e) Deposits:  The fair value of noninterest-bearing, adjustable rate deposits
    and deposits without fixed maturity dates is the amount payable upon demand
    at the reporting date.  The fair value of fixed-rate interest-bearing
    deposits with fixed maturity dates was estimated by discounting the cash
    flows using rates currently offered for deposits of similar remaining
    maturities.

(f) Off-balance-sheet instruments:  The fair value of commitments to extend
    credit is estimated using fees currently charged to enter into similar
    agreements, taking into account the remaining terms of the agreements and
    the present creditworthiness of the counterparties.  The fair values of
    standby and commercial letters of credit are based on fees currently charged
    for similar agreements or on the estimated cost to terminate them or
    otherwise settle the obligations with the counterparties, reduced by the
    remaining net deferred income associated with such obligations.

                    (a)  This corporation is authorized to issue two classes of

          of such series then outstanding) the number of shares of any series
          subsequent to the issue of shares of that series.

        the secretary, assistant secretary or any transfer agent of the
        corporation, shall be prima facie evidence of the giving of the
        notice.

        of votes greater than the number of the shareholder's shares)
        unless such candidate's or candidates' names have been placed
        in nomination prior to the voting and the shareholder has given
        notice at the meeting prior to the voting of the shareholder's
        intention to cumulate the shareholder's votes. If any one (1)

        are elected.

        present in person or by proxy, signs a written waiver of notice or a
        consent to the holding of the meeting, or an approval of the minutes
        thereof. All such waivers, consents and approvals shall be filed with
        the corporate records or made part of the minutes of the meeting.

        of such meeting, except when the person objects, at the beginning of the
        meeting, to the transaction of any business because the meeting is not
        lawfully called or convened and except that attendance at a meeting is
        not a waiver of any right to object to the consideration of matters
        required by law or these by-laws to be included in the notice but which
        was not so included, if such objection is expressly made at the meeting;
        provided, however, that any person making such objection at the
        beginning of the meeting or to the consideration of matters required to
        be but not included in the notice may orally withdraw such objection at
        the meeting or thereafter waive such objection by signing a written
        waiver thereof or a consent to the holding of 

                                      -5-

        the meeting or the consideration of the matter or an approval of 
        the minutes of the meeting. Neither the business to be transacted
        at, nor the purpose of, any annual or special meeting of
        shareholders needs to be specified in any written waiver of
        notice, except that the general nature of a proposal to amend
        the articles of incorporation of the corporation and the
        proposals specified in subparagraphs (A) through (E) of
        subsection 1.10(c)(i) shall be so stated.

        without a meeting, and without prior notice except as
        hereinafter set forth, if a consent in writing, setting forth
        the action so taken, is signed by the holders of outstanding
        shares having not less than the minimum number of votes that
        would be necessary to authorize or take such action at a
        meeting to which all shares entitled to vote thereon were
        present and voted.

                  (c) Unless the consents of all shareholders entitled
        to vote have been solicited in writing:

                  (i) Notice of any shareholder approval without a
        meeting, by less than unanimous written consent, of (A) a
        contract or other transaction between the corporation and one
        or more of its directors or any corporation, firm or
        association in which one or more of its directors has a
        material financial interest or is also a director, (B)
        indemnification of an agent of the corporation as authorized by
        the articles of incorporation of the corporation, (C) a
        reorganization of the corporation as defined in section 181 of
        the California General Corporation Law, (D) an election to wind
        up and dissolve the corporation, or (E) the distribution of
        shares, obligations or securities of any other corporation or
        assets other than money which is not in accordance with the
        liquidation rights of preferred shares if the corporation is in
        the process of winding up, shall be given at least ten (10)
        days before the consummation of the action authorized by such
        approval; and

                  (ii) Prompt notice shall be given of the taking of
        any other corporate action, including the filling of a vacancy
        on the board of directors, approved by shareholders without a
        meeting, by less than unanimous written consent, to those
        shareholders entitled to vote who have not consented in
        writing. Such notices shall be given in the manner and shall be
        deemed to have been given as provided in Section 1.4 herein.

                  (d) Any shareholder giving a written consent, or the
        shareholder's proxyholders, or a transferee of the shares or a
        personal representative of the shareholder or their respective
        proxyholders, may revoke the consent by a writing received by
        the corporation prior to the time that written consents of the
        number of shares required to authorize the proposed action have
        been filed with the secretary of the corporation, but may not
        do so thereafter. Such revocation is effective upon its receipt
        by the secretary of the corporation.

                  Section 1.11 Proxies.
                               ------- 

                  (a) Every person entitled to vote shares or execute
        consents may authorize another person or persons to act by
        proxy with respect to such vote or consent. Any proxy
        purporting to be executed in accordance with the provisions of
        this Section 1.11 shall be presumptively valid.

                                      -6-
<PAGE>
 
                  (b) No proxy shall be valid after the expiration of
        eleven (11) months from the date thereof unless otherwise
        provided in the proxy. Every proxy continues in full force and
        effect until revoked by the person executing it prior to the
        vote pursuant thereto, except as otherwise provided in this
        Section 1.11. Such revocation may be effected by a writing
        delivered to the corporation stating that the proxy is revoked
        or by a subsequent proxy executed by, or by attendance at a
        meeting and voting in person by, the person executing the
        proxy. The dates contained on the forms of proxy presumptively
        determine the order of execution, regardless of the postmark
        dates on the envelopes in which they are mailed.

                  (c) A proxy is not revoked by the death or incapacity
        of the maker unless, before the vote is counted, written notice
        of such death or incapacity is received by the corporation.

                  (d) Except when other provision shall have been made
        by written agreement between the parties, the recordholder of
        shares that such person holds as pledgee or otherwise as
        security or which belong to another shall issue to the pledgor
        or the owner of such shares, upon demand therefor and payment
        of necessary expenses thereof, a proxy to vote or take other
        action thereon.

                  (e) A proxy which states that it is irrevocable is
        irrevocable for the period specified therein (notwithstanding
        Section 1.11(b)) when it is held by any of the following or a
        nominee of any of the following:

                  (i)  A pledgee;

                  (ii) A person who has purchased or agreed to purchase
        or holds an option to purchase the shares of a person who has
        sold a portion of such person's shares in the corporation to
        the maker of the proxy;

                  (iii) A creditor or creditors of the corporation or
        the shareholder who extended or continued credit to the
        corporation or the shareholder in consideration of the proxy if
        the proxy states that it was given in consideration of such
        extension or continuation of credit and the name of the person
        extending or continuing credit;

                  (iv) A person who has contracted to perform services
        as an employee of the corporation, if a proxy is required by
        the contract of employment and if the proxy states that it was
        given in consideration of such contract of employment, the name
        of the employee and the period of employment contracted for; or

                  (v) A person designated by or under an agreement
        under section 706 of the California General Corporation Law.

                  Notwithstanding the period of irrevocability
        specified, the proxy becomes revocable when the pledge is
        redeemed, the option or agreement to purchase is terminated,
        the seller no longer owns any shares of the corporation or
        dies, the debt of the corporation or the shareholder is paid,
        the period of employment provided for in the contract of
        employment has terminated or the agreement under section 706 of
        the California General Corporation Law has terminated. In
        addition to the foregoing subdivisions (i) through (v), a proxy
        may be made irrevocable (notwithstanding Section 1.11(b) above)
        if it is given to secure the performance of a duty or to
        protect a title, either legal or equitable, until the happening
        of events which, by its terms, discharge the obligations
        secured by it.

                  (f) A proxy may be revoked, notwithstanding a
        provision making it irrevocable, by a purchaser of shares
        without knowledge of the existence of the provision, unless the
        existence of the proxy and its irrevocability appears on the
        certificate representing such shares.

                  Section 1.12 Inspectors of Election.
                               ---------------------- 

                  (a) In advance of any meeting of shareholders, the
        board of directors may appoint any persons as inspectors of
        election to act at such meeting or any adjournment thereof. If
        inspectors of election are not so appointed, or if any person
        so appointed fails to appear or refuses to act, the chairperson
        of any such meeting may, and on the request of any shareholder
        or his or her proxy shall, make such appointment at the.
        meeting. The number of inspectors shall be either one (1) or
        three (3). If appointed at a meeting on the request of one (1)
        or more shareholders or proxies, the majority of shares
        represented in person or by proxy shall determine whether one
        (1) or three (3) inspectors are to be appointed.

                  (b) The inspectors of election shall determine the
        number of shares outstanding and the voting power of each, the
        shares represented at the meeting, the existence of a quorum
        and the authenticity, validity and effect of proxies, receive
        votes, ballots or consents, hear and determine all challenges
        and questions in any way arising in connection with the right
        to vote, count and tabulate all votes and consents, determine
        when the polls shall close, determine the result and do such
        acts as may be proper to conduct the election or vote with
        fairness to all shareholders.

                  (c) The inspectors of election shall perform their
        duties impartially, in good faith, to the best of their ability
        and as expeditiously as is practical. If there are three (3)
        inspectors of election, the decision, act or certificate of a
        majority is effective in all respects as the decision, act or
        certificate of all. Any report or certificate made by the
        inspectors of election is prima facie evidence of the facts
        stated therein.

                  Section 2.1 Powers. Subject to the California General
                              ------                                   
        Corporation Law and any limitations in the articles of
        incorporation of this corporation relating to action requiring
        shareholder authorization or approval, the business and affairs
        of the corporation shall be managed and all corporate powers
        shall be exercised by or under the direction of the board of
        directors.

                  Section 2.2 Number and Qualification of Directors.
                              ------------------------------------- 
        The number of directors of the corporation shall not be less
        than eight (8) nor more than fifteen (15) until changed by a
        by-law amending this Section 2.2 duly adopted by the vote or
        written consent of holders of a majority of the outstanding
        shares entitled to vote. The exact number of directors shall be
        fixed from time to time, within the limits specified in this
        Section 2.2, by a by-law or amendment thereof or by a
        resolution duly adopted by a vote of a majority of the shares
        entitled to vote represented at a duly held meeting at which a
        quorum is present, by the written consent of the holders of a
        majority of the outstanding shares entitled to vote, or by
        resolution of the board of directors.

                  Section 2.3 Election and Term of Office. The
                              ---------------------------     
        directors shall be elected at each annual meeting of
        shareholders, but if any such annual meeting is not held or the
        directors are not elected at any annual meeting, the directors
        may be elected at any special meeting of shareholders held for
        that purpose or by written consent in accordance with Section
        1.10. Each director, including a director elected to fill a
        vacancy, shall hold office until the expiration of the term for
        which elected and until his or her successor has been elected
        and qualified, subject to the California General Corporation
        Law and the provisions of these by-laws with respect to
        vacancies on the board.

                  Section 2.4 Resignation and Removal of Directors. Any
                              ------------------------------------     
        director may resign effective upon giving written notice to the
        chairperson of the board, the president, the secretary, or the
        board of directors of the corporation, unless the notice
        specifies a later time for the effectiveness of such
        resignation. If the resignation is effective at a 

                                      -8-
<PAGE>
 
        future time, a successor may be elected to take office when the
        resignation becomes effective. The board of directors may declare vacant
        the office of a director who has been declared of unsound mind by an
        order of court or convicted of a felony. Any or all of the directors may
        be removed without cause if such removal is approved by the affirmative
        vote of a majority of the outstanding shares entitled to vote; provided
        that no director may be removed (unless the entire board is removed)
        when the votes cast against removal (or, if such action is taken by
        written consent, the shares held by persons not consenting in writing to
        such removal) would be sufficient to elect such director if voted
        cumulatively at an election at which the same total number of votes were
        cast (or, if such action is taken by written consent, all shares
        entitled to vote were voted) and the entire number of directors
        authorized at the time of the director's most recent election were then
        being elected. No reduction of the authorized number of directors shall
        have the effect of removing any director prior to the expiration of his
        or her term of office.

                  Section 2.5 Vacancies. A vacancy or vacancies on the
                              ---------                               
        board of directors shall exist on the death, resignation or
        removal of any director, or if the board declares vacant the
        office of a director if he or she is declared of unsound mind
        by an order of court or is convicted of a felony, or if the
        authorized number of directors is increased, or if the
        shareholders fail to elect the full authorized number of
        directors to be voted for at any shareholders' meeting at which
        an election of directors is held. Vacancies on the board of
        directors (except vacancies created by the removal of a
        director) may be filled by a majority of the directors then in
        office, whether or not less than a quorum, or by a sole
        remaining director. The shareholders may elect a director at
        any time to fill any vacancy not filled by the directors or
        which occurs by reason of the removal of a director. Any such
        election by written consent of shareholders shall require the
        consent of a majority of the outstanding shares entitled to
        vote. If the resignation of a director states that it is to be
        effective at a future time, a successor may be elected to take
        office when the resignation becomes effective.

                  Section 2.6 Place of Meetings. Regular and special
                              -----------------                     
        meetings of the board of directors may be he[d at any place
        within the State of California which has been designated in the
        notice of the meeting, or, if not stated in the notice or there
        is no notice, designated by resolution or by written consent of
        all of the members of the board 3f directors. If the place of a
        regular or special meeting is not designated in the notice or
        fixed by a resolution of the board or consented to in writing
        by all members of the board of directors, it shall be held at
        the corporation's principal administrative office.

                  Section 2.7 Organizational and Regular Meetings.
                              ----------------------------------- 
        Immediately following each annual shareholders' meeting, the
        board of directors shall hold an organizational meeting to
        elect officers and transact other business. Such meeting shall
        be held at the same place as the annual meeting or such other
        place as shall be fixed by the board of directors. The regular
        meetings of the board of directors shall be held at such times
        and places as are fixed by the board. Call and notice of
        regular meetings of the board of directors shall not be
        required and is hereby dispensed with.

                  Section 2.8 Special Meetings. Special meetings of the
                              ----------------                         
        board of directors for any purpose or purposes may be called at
        any time by the chairperson of the board, the chief executive
        officer, the president, any vice president, the secretary or
        any two directors. Notice of the time and place of special
        meetings shall be delivered personally to each director or by
        telephone or telegraph or sent to the director by mail. In case
        notice is given by mail or telegram, it shall be sent, charges
        prepaid, addressed to the director at his or her address
        appearing on the corporate records or if it is not on these
        records or is not readily ascertainable, at the place where the
        meetings of the directors are regularly held. If notice is
        delivered personally or given by telephone or telegraph, it
        shall be given or delivered to the telegraph office at least
        twenty-four (24) hours before the meeting. If notice is mailed
        it shall be deposited in the United States mail at least four
        (4) days before the meeting. Such mailing, telegraphing or
        delivery, personally or by telephone, as provided in this
        Section 2.9, shall be due, legal and personal notice to such
        director. A notice or waiver of notice need not specify the
        purpose of any regular or special meeting of the board of
        directors.

                              ------                              
        number of directors shall constitute a quorum of the board of
        directors for the transaction of business. Every act or
        decision done or made by a majority of the directors present at
        a meeting duly held at which a quorum is present is the act of
        the board of directors, subject to the provisions of section
        310 and subdivision (e) of section 317 of the California
        General Corporation Law. A meeting at which a quorum is
        initially present may continue to transact business
        notwithstanding the withdrawal of directors, provided that any
        action taken is approved by at least a majority of the required
        quorum for such meeting.

                  Section 2.10 Waiver of Notice or Consent. The
                               ---------------------------     
        transactions of any meeting of the board of directors, however
        called and noticed or wherever held, shall be as valid as
        though had at a meeting duly held after regular call and
        notice, if a quorum is present and if, either before or after
        the meeting, each of the directors not present or who though
        present has prior to the meeting or at its commencement
        protested the lack of proper notice to him or her, signs a
        written waiver of notice, or a consent to holding the meeting,
        or an approval of the minutes of the meeting. All such waivers,
        consents and approvals shall be filed with the corporate
        records or made a part of the minutes of the meeting. A notice
        or waiver of notice need not specify the purpose of any regular
        or special meeting of the board of directors. Notice of a
        meeting need not be given to any director who signs a waiver of
        notice, whether before or after the meeting, or who attends the
        meeting without protesting, prior to or at its commencement,
        the lack of notice to such director.

                  Section 2.11 Adjournment. A majority of the directors
                               -----------                             
        present, whether or not a quorum is present, may adjourn any
        meeting to another time and place. If the meeting is not
        adjourned for more than 24 hours, notice of the adjournment to
        another time or place shall be given prior to the time of the
        adjourned meeting to the directors who were not present at the
        time of the adjournment.

                  Section 2.12 Meeting by Conference Telephone. Members
                               -------------------------------         
        of the board of directors may participate in a meeting through
        use of conference telephone or similar communications
        equipment, as long as all members participating in such meeting
        can hear one another. Participation by directors in a meeting
        in the manner provided in this Section 2.13 constitutes
        presence in person at such meeting.

                  Section 2.13 Action Without a Meeting. Any action
                               ------------------------            
        required or permitted to be taken by the board of directors may
        be taken without a meeting, if all members of the board of
        directors shall individually or collectively consent in writing
        to such action. Such written consent or consents shall be filed
        with the minutes of the proceedings of the board of directors.
        Such action by written consent shall have the same force and
        effect as a unanimous vote of such directors.

                  Section 2.14 Fees and Compensation. Directors and
                               ---------------------               
        members of the committees may receive such compensation, if
        any, for their services, and such reimbursement for expenses,
        as may be fixed or determined by resolution of the board of
        directors.

                  Section 2.15 Committees. The board of directors may,
                               ----------                             
        by resolution adopted by a majority of the authorized number of
        directors, designate one (1) or more committees, each
        consisting of two (2) or more directors, to serve at the
        pleasure of the board of directors. The board of directors may
        designate one (1) or more directors as alternate members of any
        committee, who may replace any absent member at any meeting of
        the committee. The board of directors may delegate to any such

                 Section 2.16 Indemnification of Agents. The board of directors
                              -------------------------                        
       may authorize the Corporation to indemnify an agent, as defined in
       section 317 of the California Corporations Code, to the fullest extent
       permitted by law, including, but not limited to, the California General
       Corporation Law.

                 (a)    Indemnification of Directors and Officers. Each person
                        -----------------------------------------             
       who was or is a party or is threatened to be made a party to or is
       involved in any threatened, pending or completed action, suit or
       proceeding, formal or informal, whether brought in the name of the
       corporation or otherwise and whether of a civil, criminal, administrative
       or investigative nature (hereinafter a 'proceeding'), by reason of the
       fact that he or she, or a person of whom he or she is the legal
       representative, is or was a director or officer of the corporation or is
       or was serving at the request of the corporation as a director, officer,
       employee or agent of another corporation or of a partnership, joint
       venture, trust or other enterprise, including service with respect to
       employee benefit plans, whether the basis of such proceeding is an
       alleged action or inaction in an official capacity or in any other
       capacity while serving as a director or officer, shall, subject to the
       terms of any agreement between the corporation and such person, be
       indemnified and held harmless by the corporation to the fullest extent
       permissible under California law and the corporation's Articles of
       Incorporation, against all costs, charges, expenses, liabilities and
       losses (including attorneys' fees, judgments, fines, ERISA excise tax or
       penalties and amounts paid or to be paid in settlement) reasonably
       incurred or suffered by such person in connection therewith, and such
       indemnification shall continue as to a person who has ceased to be a
       director or officer and shall inure to the benefit of his or her heirs,
       executors and administrators; provided, however, that (a) the corporation
       shall indemnify any such person seeking indemnification in connection
       with a proceeding (or part thereof) initiated by such person only if such
       proceeding (or part thereof) was authorized by the board of directors of
       the corporation, and (b) the corporation shall indemnify such person
       seeking indemnification in connection with a proceeding (or part thereof)
       other than a proceeding by or in the name of the corporation to procure a
       judgment in its favor only if any settlement of such a proceeding is
       approved in writing by the corporation, and (c) no such person shall be
       indemnified (i) except to the extent that the aggregate of losses to be
       indemnified exceeds the amount of such losses for which the director or
       officer is paid pursuant to any directors' and officers' liability
       insurance policy maintained by the corporation; (ii) on the account of
       any suit in which judgment is rendered against such person for an
       accounting of profits made from the purchase or sale by such person of
       securities of the corporation pursuant to the provisions of Section 16(b)
       of the Securities Exchange Act of 1934 and amendments thereto or similar
       provisions of any federal, state or local statutory law; (iii) if a court
       of competent jurisdiction finally determines that any indemnification
       hereunder is unlawful; (iv) for any acts or omissions or transactions
       from which a director may not be relieved of liability as set forth in
       the exception to paragraph 10 of Section 204(a) of the General
       Corporation Law of the State of California ('GCL'); and (v) as to
       circumstances in which indemnity is expressly prohibited by Section 317
       of the GCL. The right to indemnification conferred in this Section 2.16
       shall be a contract right and shall include the right to be paid by the
       corporation expenses incurred in defending any proceeding in advance of
       its final disposition; provided, however, that if

                                      -11-
<PAGE>
 
       the GCL requires the payment of such expenses incurred by a
       director or officer in his or her capacity as a director or officer (and
       not in any other capacity in which service was or is rendered by such
       person while a director or officer, including, without limitation,
       service to an employee benefit plan) in advance of the final disposition
       of a proceeding, such advances shall be made only upon delivery to the
       corporation of an undertaking, by or on behalf of such director or
       officer, to repay all amounts to the corporation if it shall be
       ultimately determined that such person is not entitled to be indemnified.

                  (b) Indemnification of Employees and Agents. A person
                      ---------------------------------------          
        who was or is a party or is threatened to be made a party to or
        is involved in any proceedings by reason of the fact that he or
        she is or was an employee or agent of the corporation or is or
        was serving at the request of the corporation as an employee or
        agent of another enterprise, including service with respect to
        employee benefit plans, whether the basis of such proceeding is
        an alleged action or inaction in an official capacity or in any
        other capacity while serving as an employee or agent, may,
        subject to the terms of any agreement between the corporation
        and such person, be indemnified and held harmless by the
        corporation to the fullest extent permitted by California law
        and the corporation's Articles of Incorporation, against all
        costs, charges, expenses, liabilities and losses (including
        attorneys' fees, judgments, fines, ERISA excise taxes or
        penalties and amounts paid or to be paid in settlement),
        reasonably incurred or suffered by such person in connection
        therewith. The immediately preceding sentence is not intended
        to be and shall not be considered to confer a contract right on
        any employee or agent (other than directors and officers) of
        the corporation.

                  (c) Action to Enforce Rights Under this Section. If a
                      -------------------------------------------      
        claim under this Section 2.16 is not paid in full by the
        corporation within 30 days after a written claim has been
        received by the corporation, the claimant may at any time
        thereafter bring suit against the corporation to recover the
        unpaid amount of the claim and, if successful in whole or in
        part, the claimant shall also be entitled to be paid the
        expense of prosecuting such claim. Neither the failure of the
        corporation (including its board of directors, independent
        legal counsel, or its shareholders) to have made a
        determination prior to the commencement of such action that
        indemnification of the claimant is permissible in the
        circumstances because he or she has met the applicable standard
        of conduct, if any, nor an actual determination by the
        corporation (including it board of directors, independent..
        legal counsel, or its shareholders) that the claimant has not
        met the applicable standard of conduct, shall be a defense to
        the action or create a presumption for the purpose of an action
        that the claimant has not met the applicable standard of
        conduct.

                  (d) Entitlement to Expenses. Notwithstanding any
                      -----------------------                     
        other provision of this Section 2.16, to the extent that a
        director, officer or agent has been successful on the merits or
        otherwise (including the dismissal of an action without
        prejudice or the settlement of a proceeding or action without
        admission of liability) in defense of any proceeding referred
        to in this Section 2.16 or in defense of any claim, issue or
        matter therein, he or she shall be indemnified against expenses
        (including attorneys' fees) actually and reasonably incurred in
        connection therewith.

                  (e) Non-Exclusivity. The right to indemnification
                      ---------------                              
        provided by this Section 2.16 shall not be exclusive of nor
        limit any other right which any person may have or hereafter
        acquire under any statute, bylaw, agreement, vote of
        shareholders or disinterested directors or otherwise.

                  (f) Insurance. The corporation may maintain
                      ---------                              
        insurance, to the extent reasonably available, at its expense,
        to protect itself and any director, officer, employee or agent
        of the corporation or another corporation, partnership, joint
        venture, trust or other enterprise, including employee benefit
        plans, against any expense, liability or loss, whether or not
        the corporation would have the power to indemnify such person
        against such expense, liability or loss under the law. The
        corporation may create a trust fund, grant a security interest
        or use other means (including, without limitation, a letter of
        credit) to ensure the payment of such sums as may become
        necessary to effect indemnification as provided herein.

                                      -12-
<PAGE>
 
                  (g) Expenses as a Witness. To the extent that any
                      ---------------------                        
        director, officer, employee or agent of the corporation is by
        reason of such position, or a position with another entity at
        the request of the corporation, a witness in any action, suit
        or proceeding, he or she shall be indemnified against all costs
        and expenses actually and reasonably incurred by him or her on
        his or her behalf in connection therewith.

                  (h) Indemnity Agreements. The corporation may,
                      --------------------                      
        without shareholder approval, enter into agreements with any
        director, officer, employee or agent of the corporation or any
        person who serves at the request of the corporation as a
        director, officer, trustee, partner, employee or agent of
        another corporation or a partnership, joint venture, trust or
        other enterprise, including employee benefit plans, providing
        for indemnification to the fullest extent permissible under the
        law and the corporation's Articles of Incorporation.

                  (i) Severability. Each and every paragraph, sentence,
                      ------------                                     
        term and provision of this Section 2.16 is separate and
        distinct so that if any paragraph, sentence, term or provision
        hereof shall be held to be invalid or unenforceable for any
        reason, such invalidity or unenforceability shall not affect
        the validity or unenforceability of any other paragraph,
        sentence, term or provision hereof. To the extent required, any
        paragraph, sentence, term or provision of this Section 2.16 may
        be modified by a court of competent jurisdiction to preserve
        its validity and to provide the claimant with, subject to the
        limitations set forth in this Section 2.16 and any agreement
        between the corporation and claimant, the broadest possible
        indemnification permitted under applicable law.

                  (j) Entities Merged with this Corporation. No
                      -------------------------------------    
        provision of this Section 2.16 shall be applicable and unless
        otherwise required by California law indemnification shall not
        be permitted in respect of any acts, omissions or transactions
        of any person while serving as a director, officer, employee or
        agent of any corporation which shall have been or shall
        hereafter be merged into or otherwise combined with this
        corporation, or of another enterprise in respect of which such
        person was serving as a director, officer, employee or agent at
        the request of any such other corporation, or of any enterprise
        controlling, controlled by or under common control with any
        such other corporation, unless specifically approved by a
        majority vote of the board of directors of this corporation.

                  (k) Repeals. Any repeal or modification of this
                      -------                                    
        Section 2.16 (however effected) shall not adversely affect any
        right of indemnification of a director, officer, employee or
        agent existing at the time of such repeal or modification with
        respect to any act, omission or transaction occurring prior to
        such repeal or modification.

        officer may only act in one (1) capacity when joint execution
        or action by two (2) officers is required.

                             1992 STOCK OPTION PLAN
                             ----------------------


     ARTICLE 1.  INTRODUCTION.
     ----------  ------------ 

     The Plan was adopted by the Board on June 30, 1992, subject to approval by
the Company's shareholders at the 1992 annual meeting of shareholders. The
purpose of the Plan is to promote the long-term success of the Company and the
creation of shareholder value by (a) encouraging Non-Employee Directors and Key
Employees to focus on critical long-range objectives, (b) encouraging the
attraction and retention of Non-Employee Directors and Key Employees with
exceptional qualifications and (c) linking Non-Employee Directors and Key
Employees directly to shareholder interests through increased stock ownership.
The Plan seeks to achieve this purpose by providing for awards in the form of
Options, which may constitute incentive stock options or nonstatutory stock
options.

     The Plan shall be governed by, and construed in accordance with, the laws
of the State of California.

     ARTICLE 2.  ADMINISTRATION.
     ----------  --------------

     2.1  The Committee.  The Plan shall be administered by the Committee
          -------------                                                  
appointed by the Board.

     2.2  Committee Responsibilities.  The Committee shall select the Non-
          --------------------------                                     
Employee Directors and Key Employees who are to receive Options under the Plan,
determine the number, vesting requirements and other conditions of such Options,
interpret the Plan, and make all other decisions relating to the operation of
the Plan.  The Committee may adopt such rules or guidelines as it deems
appropriate to implement the Plan.  The Committee's determinations under the
Plan shall be final and binding on all persons.

     ARTICLE 3.  LIMITATION ON AWARDS.
     ----------  -------------------- 

     3.1  Basic Limitation.  The aggregate number of Common Shares subject to
          ----------------                                                   
Options awarded under the Plan shall be 67,550; increased by any shares
attributable to options that are forfeited, lapse, or terminate for any reason
before being exercised under the Napa National Bancorp 1982 Stock Option Plan.
In no event will the number of Common Shares subject to Options awarded under
the Plan that are attributable to options that were forfeited, lapsed or
terminated for any other reason before being exercised under the Napa National
Bancorp 1982 Stock Option Plan exceed 158,800.

     3.2  Additional Shares.  If any Options are forfeited, lapse, or terminate
          -----------------                                                    
for any other reason before being exercised,

                                      -1-
<PAGE>
 
then the Common Shares subject to such Options shall again become available for
the purposes of the Plan. The limitation of this Article 3 shall be subject to
adjustment pursuant to Article 7.

     ARTICLE 4.  ELIGIBILITY.
     ----------  ----------- 

     4.1  General Rule.  Only Non-Employee Directors and Key Employees shall be
          ------------                                                         
eligible for designation as Optionees by the Committee.  In addition, only Key
Employees shall be eligible for the grant of ISOs.

     4.2  Non-Employee Directors.  Any other provision of the Plan
          ----------------------                                  
notwithstanding, the participation of Non-Employee Directors in the Plan shall
be subject to the following restrictions:

         (a) Non-Employee Directors shall receive no grants other than the NSOs
     described in this Section 4.2.

         (b) Each Non-Employee Director who first joins the Board after July 14,
     1992, shall receive an NSO covering 10,000 Common Shares on the first
     business day after his or her initial election or appointment to the Board.
     (The number of Common Shares included in an NSO granted under this
     Subsection (b) shall be subject to adjustment under Article 7.)

         (c) NSOs granted under Subsection (b) above shall become exercisable
     immediately.

         (d) The Exercise Price under all NSOs granted to a Non-Employee
     Director under this Section 4.2 shall be equal to 100 percent of the Fair
     Market Value of a Common Share on the date of grant, payable in cash or in
     one of the forms described in Sections 6.2 or 6.3.

         (e) All NSOs granted to a Non-Employee Director under this Section 4.2
     shall terminate on the earliest of (i) the 10th anniversary of the date of
     grant, (ii) the date of the termination of such Non-Employee Director's
     service for any reason other than death or total and permanent disability
     or (iii) the date 30 days after the termination of such Non-Employee
     Director's service because of death or total and permanent disability.

     4.3  Ten-Percent Shareholders.  A Key Employee who owns more than 10
          ------------------------                                       
percent of the total combined voting power of all classes of outstanding stock
of the Company or any of its Subsidiaries shall not be eligible for the grant of
an ISO unless (a) the Exercise Price under such ISO is at least 110 percent of
the Fair Market Value of a Common Share on the date of grant and (b) such ISO by
its terms is not exercisable after the expiration of five years from the date of
grant.

                                      -2-
<PAGE>
 
     4.4  Attribution Rules.  For purposes of Section 4.3, in determining stock
          -----------------                                                    
ownership, a Key Employee shall be deemed to own the stock owned (directly or
indirectly) by or for his or her brothers, sisters, spouse, ancestors and lineal
descendants. Stock owned (directly or indirectly) by or for a corporation,
partnership, estate or trust shall be deemed to be owned proportionately by or
for its shareholders, partners or beneficiaries.  Stock with respect to which
the Key Employee holds an option shall not be counted.

     4.5  Outstanding Stock.  For purposes of Section 4.3, "outstanding stock"
          -----------------                                                   
shall include all stock actually issued and outstanding immediately after the
grant of the ISO to the Key Employee.  "Outstanding stock" shall not include
shares authorized for issuance under outstanding options held by the Key
Employee or by any other person.

     ARTICLE 5.  TERMS OF OPTIONS.
     ----------  ---------------- 

     5.1  Stock Option Agreement.  Each grant of an Option under the Plan shall
          ----------------------                                               
be evidenced by a Stock Option Agreement between the Optionee and the Company.
Such Option shall be subject to all applicable terms and conditions of the Plan
and may be subject to any other terms and conditions which are not inconsistent
with the Plan and which the Committee deems appropriate for inclusion in a Stock
Option Agreement.  The provisions of the various Stock Option Agreements entered
into under the Plan need not be identical.  If the Optionee is a Key Employee,
the Committee may designate all or any part of the Option as an ISO.

     5.2  Options Nontransferable.  No Option or interest therein may be
          -----------------------                                       
transferred, assigned, pledged or hypothecated by the Optionee during his or her
lifetime, whether by operation of law or otherwise, or be made subject to
execution, attachment or similar process.

     5.3  Number of Shares; Tax Status.  Each Stock Option Agreement shall
          ----------------------------                                    
specify the number of Shares subject to the Option and shall provide for the
adjustment of such number in accordance with Article 7.  The Stock Option
Agreement shall also specify whether the Option is an ISO or an NSO.

     5.4  Exercise Price.  Each Stock Option Agreement shall specify the
          --------------                                                
Exercise Price.  The Exercise Price under an ISO shall not be less than 100
percent of the Fair Market Value of a Common Share on the date of grant, except
as otherwise provided in Section 4.3.  The Exercise Price under an NSO shall not
be less than 100 percent of the Fair Market Value of a Common Share on the date
of grant.  Subject to the preceding two sentences, the Exercise Price under any
Option shall be determined by the Committee.  The Exercise Price shall be
payable in accordance with Article 6.

                                      -3-
<PAGE>
 
     5.5  Exercisability and Term.  Each Stock Option Agreement shall specify
          -----------------------                                            
the date when all or any installment of the Option is to become exercisable and
shall provide for immediate exercisability of the entire Option in the event of
a Change in Control with respect to the Company.  The Stock Option Agreement
shall also specify the term of the Option.  The term of an Option shall in no
event exceed 10 years from the date of grant, and Section 4.3 may require a
shorter term for an ISO.  Subject to this Section 5.5, the Committee shall
determine when all or any part of an Option is to become exercisable and when
such Option is to expire.  A Stock Option Agreement may provide for accelerated
exercisability upon the Optionee's death, disability or retirement or other
events and may provide for expiration prior to the end of its term in the event
of the termination of the Optionee's service.

     5.6  Modification, Extension and Assumption of Options. Within the
          -------------------------------------------------            
limitations of the Plan, the Committee may modify, extend or assume outstanding
options or may accept the cancellation of outstanding options (whether granted
by the Company or by another issuer) in return for the grant of new options for
the same or a different number of shares and at the same or a different exercise
price.  The foregoing notwithstanding, no modification of an Option shall,
without the consent of the Optionee, alter or impair his or her rights or
obligations under such Option.

     ARTICLE 6.  PAYMENT FOR OPTION SHARES.
     ----------  ------------------------- 

     6.1  General Rule.  The entire Exercise Price of Common Shares issued upon
          ------------                                                         
exercise of Options shall be payable in cash at the time when such Common Shares
are purchased, except as follows:

         (a) In the case of an ISO granted under the Plan, payment shall be made
    only pursuant to the express provisions of the applicable Stock Option
    Agreement. However, the Committee may specify in the Stock Option Agreement
    that payment may be made pursuant to Section 6.2, 6.3 or 6.4.

         (b) In the case of an NSO, the Committee may at any time accept payment
    pursuant to Section 6.2, 6.3 or 6.4.

     6.2  Surrender of Stock.  To the extent that this Section 6.2 is
          ------------------                                         
applicable, payment for all or any part of the Exercise Price may be made with
Common Shares which have already been owned by the Optionee for more than six
months and which are surrendered to the Company.  Such Common Shares shall be
valued at their Fair Market Value on the date when the new Common Shares are
purchased under the Plan.

     6.3  Exercise/Sale.  To the extent that this Section 6.3 is applicable,
          -------------                                                     
payment may be made by the delivery (on a form

                                      -4-
<PAGE>
 
prescribed by the Company) of an irrevocable direction to a securities broker
approved by the Company to sell Common Shares and to deliver all or part of the
sales proceeds to the Company in payment of all or part of the Exercise Price
and any withholding taxes.

     6.4  Other Forms of Payment.  To the extent that this Section 6.4 is
          ----------------------                                         
applicable, payment may be made in any other form approved by the Committee,
consistent with applicable laws, regulations and rules.

     ARTICLE 7.  PROTECTION AGAINST DILUTION.
     ----------  --------------------------- 

     7.1  General.  In the event of a subdivision of the outstanding Common
          -------                                                          
Shares, a declaration of a dividend payable in Common Shares, a declaration of a
dividend payable in a form other than Common Shares in an amount that has a
material effect on the price of Common Shares, a combination or consolidation of
the outstanding Common Shares (by reclassification or otherwise) into a lesser
number of Common Shares, a recapitalization, a spinoff or a similar occurrence,
the Committee may make appropriate adjustments in one or more of (a) the number
of' Options available for future awards under Article 3, (b) the number of
Options included in awards to Non-Employee Directors under Section 4.2, (c) the
number of Common Shares covered by each outstanding Option or (d) the Exercise
Price under each outstanding Option.

     7.2  Reorganizations.  In the event that the Company is a party to a merger
          ---------------                                                       
or other reorganization, outstanding Options shall be subject to the agreement
of merger or reorganization. Such agreement shall provide for the assumption or
substitution of outstanding Options by the surviving corporation or its parent,
for their continuation by the Company (if the Company is a surviving
corporation), for accelerated vesting or for settlement in cash.

may be, shall be determined by the Stock Option Committee of the Board of

            5. The number of shares of Common Stock covered hereby and the price

Stock issuable upon the exercise of this option the number and kind of shares
of stock or other securities into which each outstanding share of Common Stock
shall be so changed or for which each share shall be exchanged, or to which
each such share shall be entitled, as the case may be. In addition, the
Committee shall make appropriate adjustments in the number and kind of shares
as to which this option, or portion thereof then unexercised, shall be
exercisable so that the Optionee' 5 proportionate interest in the securities of
the Company by reason of the Optionee' 5 rights hereunder shall be maintained
as before the occurrence of such event.? Such adjustment shall be made without
change in the total price as to the unexercised portion of this -option and
with a corresponding adjustment in the Option Price.

           In the event of a sale, dissolution or liquidation of the Company or
a merger or consolidation in which the Company is not the surviving or resulting
corporation (unless the Company's obligations hereunder are assumed by the
surviving or resulting corporation), options granted hereunder may be terminated
by the Committee; provided, however, that immediately prior to such sale,
                  --------- ------- 
dissolution, or liquidation, or merger or consolidation in which the Company is
not the surviving or resulting corporation, the Company shall notify the
Optionee as soon as practicable and, thereafter, this option may be exercised in
whole or in part to the extent of any unexercised portion of this option,
regardless of the vesting provisions of Section 3 of this Agreement; and,
provided, further, that such right of exercise shall be conditioned upon the
- --------- -------
execution of a final plan of dissolution or liquidation or a definitive
agreement of merger or consolidation.

          In the event of an offer by any person or entity to all shareholders
of the Company to purchase any or all shares of Common Stock (or shares of stock
or other securities which are substituted for such shares or to which such
shares are adjusted as provided in this Section 5), the option granted hereunder
may be exercised upon the commencement of such offer to the extent of any
unexercised or unvested portion of such option.

          To the extent that the foregoing adjustments relate to stock or
securities of the Company, such adjustments shall be made by the Committee,
whose determination in that respect shall be final, binding and conclusive. No
fractional shares shall be issued or delivered.

          The grant of the option granted hereunder shall not affect in any way
the right or power of the Company to make

                                       4

 adjustments, reclassifications, reorganizations or changes of its capital or
 business structure or to merge or to consolidate or to dissolve, liquidate or
 sell, or transfer all or any part of its business or assets.

          6. No partial exercise of this option will be permitted for fewer than
__________ shares of Common Stock.

          7. The Company shall have the right to cancel this option at any time
before it otherwise would have expired by its terms and to grant to the Optionee
in substitution therefor a new option stating an Option Price which is lower
(but not higher) than the Option Price stated in Section 2 of this Agreement and
which, in any case, shall be no less than the Fair Market Value of the shares
subject hereto on the date the new option is granted. The substituted option
shall not be exercisable after the expiration of ten (10) years [five (5) years
if the Optionee is a more-than-1O% shareholder] from the date of grant of this
option.

          8. If the Optionee's status as an officer or employee of the Bank is
terminated due to total or partial disability within the meaning of Section
22(e)(3) of the Code (as determined by the Committee), this option may be
exercised for a period of twelve (12) months after the date of such disability,
provided the actual date of exercise is in no event after the expiration of the
term of this option.

          If the Optionee' 5 status as an officer or employee of the Bank is
terminated by death, the executors or administrators of the Optionee' 5 estate,
or any person or persons who have acquired this option directly from the
Optionee by the Optionee' 5 will or the applicable laws of descent and
distribution, shall have the right to exercise this option, for a period of
twelve (12) months, commencing with the death of the Optionee, provided the
actual date of exercise is in no event after the expiration of the term of this
option.

          If the Optionee's status as an officer or employee of the Bank is
terminated for any of the reasons set forth in the paragraph captioned "CAUSE"
under subsection 5(c)(3) of the Plan, this option shall expire at the time
notice or advice of such termination is dispatched by the Company pursuant to
the Plan and, notwithstanding anything else herein to the contrary, neither the
Optionee nor the Optionee' 5 estate shall be entitled to exercise this option
with respect to any shares whatsoever after such termination.

          If the Optionee's status as an officer or employee of the Bank is
terminated for any reason other than those 

                                       5
<PAGE>
specified in this Section 8, this option may be exercised within three (3)
months following such termination to the extent this option was exercisable on
the date of such termination, provided the date of exercise is in no event after
the expiration of the term of this option.

          9. This option shall be exercisable during the Optionee's lifetime
only by the Optionee and shall be transferable by the Optionee only by will or
the laws of descent and distribution.

          10. Except as otherwise provided herein, the option herein granted and
the rights and privileges conferred hereby shall not be transferred, assigned,
pledged or hypothecated in any way (whether by operation of law or otherwise)
and shall not be subject to sale under execution attachment or similar process
upon the rights and privileges conferred hereby. Upon any attempt to transfer,
assign, pledge or otherwise dispose of said option, or of any right or privilege
conferred hereby, contrary to the provisions hereof 1 or upon any attempted sale
under any execution, attachment or similar process upon the rights and
privileges conferred hereby, said option and the rights and privileges conferred
hereby shall immediately become null and void.

          11. This option may be exercised by delivering to the Secretary of the
Company payment in full at the Option Price for the number of shares of Common
Stock being purchased. The Option Price may be paid by delivering, at the
discretion of the Committee, (a) cash, a certified check, an official bank check
or the equivalent thereof acceptable to the Company; (b) shares of Common Stock
with a Fair Market Value as of the date of exercise equal to the Option Price,
or (c) shares of Common Stock, with a Fair Market Value as of the date of
exercise less than the full amount of the Option Price plus cash, a certified
check, an official bank check or the equivalent thereof acceptable to the
Company equal to the remaining amount of the Option Price, in each case together
with a written notice identifying this option or the part thereof being.
exercised and specifying the number of shares of Common Stock for which payment
is being tendered. The Company shall deliver to the Optionee, which delivery
shall be not less than fifteen (15) days and not more than thirty (30) days
after the giving of such notice, without transfer or issue tax to the Optionee
(or other person entitled to exercise this option), at the principal office of
the Company, or such other place as shall be mutually acceptable, a certificate
or certificates for such shares of Common Stock dated the date that this option
was validly exercised; provided, however, that the time of such delivery
                       --------- -------
may be postponed by the Company for such period as may be required for it with
reasonable 

                                       6
<PAGE>
diligence to comply with any requirements of law. If the Option Price
is satisfied in whole or in part by delivery of shares of Common Stock, separate
stock certificates shall be issued, one or more for the number of shares of
stock received equal to the number of shares of Common Stock delivered and one
or more for the remainder of the shares received upon the exercise.

           12. Neither the Optionee nor any person claiming under or through him
shall be or have any of the rights of a shareholder of the Company in respect of
any of the shares issuable upon the exercise of this option until the date of
issuance of a stock certificate for such shares by the Company. The Optionee
shall not be entitled to the privileges of stock ownership as to any shares not
actually issued and delivered to the Optionee.

           13. Any notice to be given to the Company under the terms of this
Agreement shall be addressed to Napa National Bankcorp, in care of its
Secretary, at 1500 Third Street, P.O. Box 479, Napa, California 94559-0479, or
at such other address as the Company may hereafter designate in writing. Any
notice to be given to the Optionee shall be addressed to the Optionee at the
address set forth beneath his or her signature hereto, or at any such other
address as the Optionee may hereafter designate in writing. Any such notice
shall be deemed to have been duly given if and when enclosed in a properly
sealed envelope, addressed as aforesaid, registered and deposited, postage and
registry fee prepaid, in a post office or branch post office regularly
maintained by the United States government.

           14. Subject to the limitations on transferability contained herein,
this Agreement shall be binding upon and inure to the benefit of the heirs,
legal representatives, successors and assigns of the parties hereto.

           15. The option granted hereby is subject to the requirement that if
at any time the Board of Directors or the Committee shall determine in its
discretion that the listing or qualification of the shares of Common Stock
subject to such option on any securities exchange or under any applicable law,
or the consent or approval of any government regulatory body, is necessary or
desirable as a condition of, or in connection with, the issuance of shares under
this option, such option may not be exercised in whole or in part unless such
listing, qualification, consent or approval shall have been effected or obtained
free of any condition not acceptable to the Board of Directors or the Committee.

                                 7            

<PAGE>
          16. Unless the Optionee is required to give the notice required by
Section 17 hereof, the Optionee shall give the Company notice of any sale or
other disposition of any shares issued pursuant to the exercise of this option
not more than five (5) days after such sale or other disposition.

          The exercise of this option shall be conditioned upon the registration
of the Plan with the Securities and Exchange Commission and qualification of the
Plan with the Commissioner of Corporations of the State of California unless in
the opinion of counsel to the Company such registration and qualification is not
necessary. Further, unless the shares of Common Stock to be issued upon exercise
of this option have been effectively registered under the Securities Act of 1933
and qualified under the California Corporate Securities Law of 1968, as each is
now in force or hereafter amended, the Company shall be under no obligation to
issue any shares of Common Stock covered by this option unless the person who'
exercises such option, in whole or in part, shall give a written representation
and undertaking to the Company which is satisfactory in form and scope to
counsel to the Company and upon which, in the opinion of such counsel, the
Company may reasonably rely, that he or she is acquiring the shares of Common
Stock issued to him or her pursuant to such exercise of this option for his or
her own account as an investment and not with a view to, or for sale in
connection with, the distribution of any such shares of Common Stock, and that
he or she will make no transfer of the same except in compliance with any rules
and regulations in force at the time of such transfer under the Securities Act
of 1933, the California Corporate Securities Law of 1968, or any other
applicable law, and that if shares of Common Stock are issued without such
registration or qualification, a legend to this effect shall be endorsed upon
the securities so issued.

          17. Section 16 hereof notwithstanding, in the event the Optionee sells
or otherwise disposes of any of the shares that may be acquired hereunder within
two (2) years of the date hereof or within one (1) year of the date such shares
are acquired hereunder, the Optionee agrees to notify the Company in writing
within ten (10) days of the date of such sale or other disposition of the number
of shares sold or disposed of, the nature of the transaction, and the amount
received (if any) upon such sale or other disposition. The Optionee understands
that such a sale or other disposition may result in imposition of withholding
taxes, and agrees to remit to the Company on request any amounts requested to
satisfy any withholding tax liability.

          18. The Optionee agrees to notify in writing the Corporate Secretary
of the Company of his or her intention, if 

                                       8
<PAGE>
any, to terminate his or her employment within ten (10) days after said 
intention is formed.

           19. Subject to any employment contract with the Optionee, the terms
of employment of the Optionee shall be determined from time to time by the Bank
and the Bank shall have the right, which is hereby expressly reserved, to
terminate the employee or change the terms of the employment at any time for any
reason whatsoever, with or without good cause.

           20. Whenever shares of Common Stock are to be issued to the Optionee
in satisfaction of the rights conferred hereby, the Company shall have the right
to require the Optionee to remit to the Company an amount sufficient to satisfy
federal, state and local withholding tax requirements prior to the delivery of
any certificate or certificates for such shares. Whenever the Optionee is
required to pay to the Company an amount required to be withheld under
applicable federal and state income tax laws in connection with receipt of
shares of Common Stock upon exercise of this option, the Committee may, in its
absolute discretion, permit the Optionee to satisfy such obligation, in whole or
in part, by electing to have the Company withhold shares of Common Stock having
a value equal to the amount required to be withheld or by delivering to the
Company already-owned shares to satisfy the withholding requirement. The amount
of the withholding requirement shall include any amount agreed to be withheld at
the time the election is made, not in excess of the maximum federal and state
income tax rates applicable to the Optionee on the date that the amount of tax
to be withheld is to be determined (the "Tax Date"). The value of the shares to
be withheld or delivered will be based on their Fair Market Value on the Tax
Date. Such elections will be subject to the following restrictions: (1) the
election must be made on or before the Tax Date; (2) the election will be
irrevocable; and (3) the election will be subject to the disapproval of the
Committee. Each election by an optionee whose transactions in shares of Common
Stock are subject to Section 16(b) of the Securities Exchange Act of 1934 will
be subject to the following additional restrictions: (1) the election may not be
made within six (6) months of the grant of this option (except that this
limitation will not apply in the event death or disability of the optionee
occurs prior to the expiration of the six-month period), and (2) the election
must be made either at least six (6) months before the Tax Date or within a ten
(10) day period beginning on the third day following the release of the Company'
5 quarterly or annual summary statement of earnings.

           21. The Committee shall have the power to interpret the Plan and this
Agreement and to adopt such rules for the administration, interpretation and
application of the Plan as are consistent therewith and to interpret or revoke
any such rules. All actions taken and all interpretations and determinations
made by the committee in good faith shall be final and binding upon Optionee,
the Company and all other interested persons. No member of the Board of
Directors or of the Committee shall be personally liable for any action,
determination or interpretation made in good faith with respect to the Plan or
this Agreement.

           22.  In the event that any provisiuon of this Agreemetn shall be 
invalid or unenforceable, such provision shall be severable from, and such 
invalidity or unenforceability shall not be construed to have any effect on, the
remaining provisions of this agreement.

           IN WITNESS HEREOF, the parties hereto have executed this Agreement, 
in duplicate, the day and year first above written.

                                   ----------

           consideration, the receipt and adequacy of which are hereby
           acknowledged, the parties hereto hereby agree as follows:

                (a) This option may be exercised immediately to the extent of

<PAGE>
 
                  (g) After the expiration of ________ (___) months from the
             date of grant, this option may be exercised to the extent of an
             additional _____________________ percent (___) of the shares of
             Common Stock covered hereby.

                  (h) After the expiration of ________ (___) months from the
             date of grant, this option may be exercised to the extent of an
             additional _____________________ percent (_______%) of the shares
             of Common Stock covered hereby.

                  (i) After the expiration of _______ (___) months from the date
             of grant, this option may be exercised to the extent of an
             additional _____________________ percent (_____%) of the shares of
             Common Stock covered hereby.

                  (j) After the expiration of _______ (___) months from the date
             of grant, this option may be exercised to the extent of an
             additional _____________________ percent (_____%) of the shares of

                  (k) After the expiration of ________ (___) months from the

             additional _____________________ percent (______%) of the shares of
             Common Stock covered hereby.

             Notwithstanding any other provision of this Agreement, this
option is not exercisable after the expiration of ten (10) years and one (1)
month from the date of grant.

             4. For the purposes of this Agreement, "Fair Market Value," when
used in reference to the date of grant of this option or the date of any
surrender of Common Stock in payment for the purchase of shares pursuant to the
exercise of this option or in satisfaction of any withholding tax requirements,
as the case may be, shall be determined by the Stock Option Committee of the
Board of Directors of the Company (the "Committee") in accordance with any
reasonable valuation method, including the valuation methods set forth in
Section 20.2031-2 of the regulations promulgated under the Code.

             5. The number of shares of Common Stock covered hereby and the
price per share thereof shall be proportionately adjusted for any increase or
decrease in the number of issued and outstanding shares of Common Stock
resulting from a subdivision or consolidation of shares or the

                                       3
<PAGE>
 
payment of a stock dividend, or any other increase or decrease in the number of
issued and outstanding shares of Common Stock effected without receipt of
consideration by the Company. If the shares of Common Stock are changed into or
exchanged for a different number or kind of shares of stock or securities of the
Company or another corporation (whether by reason of reorganization, merger,
consolidation, recapitalization, reclassification, split-up, combination of
shares, or otherwise), the Optionee shall receive in substitution for each share
of Common Stock issuable upon the exercise of this option the number and kind of
shares of stock or other securities into which each outstanding share of Common
Stock shall be so changed or for which each share shall be exchanged, or to
which each such share shall be entitled, as the case may be. In addition, the
Committee shall make appropriate adjustments in the number and kind of shares as
to which this option, or portion thereof then unexercised, shall be exercisable
so that the Optionee's proportionate interest in the securities of the Company
by reason of the Optionee' 5 rights hereunder shall be maintained as before the
occurrence of such event. Such adjustment shall be made without change in the
total price as to the unexercised portion of this option and with a
corresponding adjustment in the Option Price.

           In the event of a sale, dissolution or liquidation of the Company or
a merger or consolidation in which the Company is not the surviving or resulting
corporation (unless the Company's obligations hereunder are assumed by the
surviving or resulting corporation), options granted hereunder may be terminated
by the Committee; provided, however, that immediately prior to such
                  --------- -------
sale,-dissolution, or liquidation, or merger or consolidation in which the
Company is not the surviving or resulting corporation, the Company shall notify
the Optionee as soon as practicable and, thereafter, this option may be
exercised in whole or in part to the extent of any unexercised portion of this
option, regardless of the vesting provisions of Section 3 of this Agreement;
and, provided, further, that such right of exercise shall be conditioned
     --------  ------- 
upon the execution of a final plan of dissolution or liquidation or a
definitive agreement of merger or consolidation.

           In the event of an offer by any person or entity to all shareholders
of the Company to purchase any or all shares of Common Stock (or shares of stock
or other securities which are substituted for such shares or to which such
shares are adjusted as provided in this Section 5), the option granted hereunder
may be exercised upon the commencement of such offer to the extent of any
unexercised or unvested portion of such option.

                                       4
<PAGE>
 
            To the extent that the foregoing adjustments relate to stock or
 securities of the Company, such adjustments shall be made by the Committee,
 whose determination in that respect shall be final, binding and conclusive. No
 fractional shares shall be issued or delivered.

            The grant of the option granted hereunder shall not affect in any
 way the right or power of the Company to make adjustments, reclassifications,
 reorganizations or changes of its capital or business structure or to merge or
 to consolidate or to dissolve, liquidate or sell, or transfer all or any part
 of its business or assets.

             6. No partial exercise of this option will be permitted for fewer
 than ___________ shares of Common Stock.

             7. Unless the Optionee is a nonemployee director of the Company,
 the Company shall have the right to cancel this option at any time before it
 otherwise would have expired by its terms and to grant to the Optionee in
 substitution therefor a new option stating an Option Price which is lower (but
 not higher) than the Option Price stated in Section 2 of this Agreement and
 which, in any case, shall be no less than the Fair Market Value of the shares
 subject hereto on the date the new option is granted. The substituted option
 shall not be exercisable after the expiration of ten (10) years and one (1)
 month from the date of grant of this option.

              8. If the Optionee's status as a nonemployee director of the
 Company or an officer or employee of the Bank is terminated due to total or
 partial disability within the meaning of Section 22(e)(3) of the Code (as
 determined by the Committee), this option may be exercised for a period of
 twelve (12) months after the date of such disability, provided the actual date
 of exercise is in no event after the expiration of the term of this option.

              If the Optionee's status as a nonemployee director of the Company
 or an officer or employee of the Bank is terminated by death, the executors or
 administrators of the Optionee's estate, or any person or persons who have
 acquired this option directly from the Optionee by the Optionee's will or the
 applicable laws of descent and distribution, shall have the right to exercise
 this option, for a period of twelve (12) months, commencing with the death of
 the Optionee, provided the actual date of exercise is in no event after the
 expiration of the term of this option.

              If the Optionee's status as a nonemployee director of the Company
 or an officer or employee of the Bank is terminated for any of the reasons set
 forth in the paragraph
                                       5
<PAGE>
 
 captioned "CAUSE" under subsection 5(c)(3) of the Plan, this option shall
 expire at the time notice or advice of such termination is dispatched by the
 Company pursuant to the Plan and, notwithstanding anything else herein to the
 contrary, neither the Optionee nor the Optionee' 5 estate shall be entitled to
 exercise this option with respect to any shares whatsoever after such
 termination.

           If the Optionee's status as a nonemployee director of the Company or
 an officer or employee of the Bank is terminated for any reason other than
 those specified in this Section 8, this option may be exercised within three
 (3) months following such termination to the extent this option was exercisable
 on the date of such termination, provided the date of exercise is in no event
 after the expiration of the term of this option.

           Notwithstanding the foregoing provisions of this Section 8, if the
 status of the Optionee as a nonemployee director is terminated because it is
 determined that the Optionee is, or in the view of a Federal bank regulatory
 agency would be, precluded from continuing service as a member of the Board of
 Directors of the Company by virtue of a concurrent relationship of the Optionee
 with an organization primarily engaged in the issue, underwriting or
 distribution of securities and if that Optionee shall, as an independent
 advisor or consultant, provide without other remuneration advice, services or
 other assistance to the Company or the Bank of at least the same quality or
 quantity as the Optionee rendered as a director, then this option shall remain
 in full force until the earlier of (i) expiration according to the terms of
 this option, (ii) termination because of death, disability or cause as
 described above and in accordance with those paragraphs applicable to such
 reasons for termination, or (iii) a determination made by the Board of
 Directors of the Company in its sole discretion that the Optionee's assistance
 to the Company or Bank has ceased to be of at least the same quality or
 quantity as the Optionee rendered while a director. In the event that this
 option is terminated pursuant to such a Board of Directors' determination, the
 Optionee may within three (3) months of that determination exercise this option
 to the extent this option was exercisable by the Optionee on the date of such
 determination.

           9. This option shall be exercisable during the Optionee's lifetime
 only by the Optionee and shall be transferable by the Optionee only by will or
 the laws of descent and distribution.

           10. Except as otherwise provided herein, the option herein granted
 and the rights and privileges conferred hereby

                                       6
<PAGE>
 
shall not be transferred, assigned, pledged or hypothecated in any way (whether
by operation of law or otherwise) and shall not be subject to sale under
execution attachment or similar process upon the rights and privileges conferred
hereby. Upon any attempt to transfer, assign, pledge or otherwise dispose of
said option, or of any right or privilege conferred hereby, contrary to the
provisions hereof, or upon any attempted sale under any execution, attachment or
similar process upon the rights and privileges conferred hereby, said option and
the rights and privileges conferred hereby shall immediately become null and
void.

           11. This option may be exercised by delivering to the Secretary of
the Company payment in full at the Option Price for the number of shares of
Common Stock being purchased. The Option Price may be paid by delivering, at the
discretion of the Committee, (a) cash, a certified check, an official bank check
or the equivalent thereof acceptable to the Company; (b) shares of Common Stock
with a Fair Market Value as of the date of exercise equal to the Option Price,
or (c) shares of Common Stock, with a Fair Market Value as of the date of
exercise less than the full amount of the Option Price plus cash, a certified
check, an official bank check or the equivalent thereof acceptable to the
Company equal to the remaining amount of the Option Price, in each case together
with a written notice identifying this option or the part thereof being
exercised and specifying the number of shares of Common Stock for which payment
is being tendered. The Company shall deliver to the Optionee, which delivery
shall be not less than fifteen (15) days and not more than thirty (30) days
after the giving of such notice, without transfer or issue tax to the Optionee
(or other person entitled to exercise this option), at the principal office of
the Company, or such other place as shall be mutually acceptable, a certificate
or certificates for such shares of Common Stock dated the date that this option
was validly exercised; provided, however, that the time of such delivery
                       --------- -------
may be postponed by the Company for such period as may be required for it with
reasonable diligence to comply with any requirements of law. If the Option Price
is satisfied in whole or in part by delivery of shares of Common Stock, separate
stock certificates shall be issued, one or more for the number of shares of
stock received equal to the number of shares of Common Stock delivered and one
or more for the remainder of the shares received upon the exercise.

           12. Neither the Optionee nor any person claiming under or through him
shall be or have any of the rights of a shareholder of the Company in respect of
any of the shares issuable upon the exercise of this option until the date of
issuance of a stock certificate for such shares by the

                                       7
<PAGE>
 
Company. The Optionee shall not be entitled to the privileges of stock
ownership as to any shares not actually issued and delivered to the Optionee.

           13. Any notice to be given to the Company under the terms of this
Agreement shall be addressed to Napa National Bankcorp, in care of its
Secretary, at 1500 Third Street, P.O. Box 479, Napa, California 94559-0479, or
at such other address as the Company may hereafter designate in writing. Any
notice to be given to the Optionee Shall be addressed to the Optionee at the
address set forth beneath his or her signature hereto, or at any such other
address as the Optionee may hereafter designate in writing. Any such notice
shall be deemed to have been duly given if and when enclosed in a properly
sealed envelope, addressed as aforesaid, registered and deposited, postage and
registry fee prepaid, in a post office or branch post office regularly
maintained by the United States government.

           14. Subject to the limitations on transferability contained herein,
this Agreement shall be binding upon and inure to the benefit of the heirs,
legal representatives, successors and assigns of the parties hereto.

           15. The option granted hereby is subject to the requirement that if
at any time the Board of Directors or the Committee shall determine in its
discretion that the listing or qualification of the shares of Common Stock
subject to such option on any securities exchange or under any applicable law,
or the consent or approval of any government regulatory body, is necessary or
desirable as a condition of, or in connection with, the issuance of shares under
this option, such option may not be exercised in whole or in part unless such
listing, qualification, consent or approval shall have been effected or obtained
free of any condition not acceptable to the Board of Directors or the Committee.

           16. Unless the Optionee is required to give the notice required by
Section 17 hereof, the Optionee shall give the Company notice of any sale or
other disposition of any shares issued pursuant to the exercise of this option
not more than five (5) days after such sale or other disposition.

           The exercise of this option shall be conditioned upon the
registration of the Plan with the Securities and Exchange Commission and
qualification of the Plan with the Commissioner of Corporations of the State of
California unless in the opinion of counsel to the Company such registration and
qualification is not necessary. Further, unless the shares of Common Stock to be
issued upon exercise of this option have been effectively registered under the
Securities Act of 1933

                                       8
<PAGE>
 
and qualified under the California Corporate Securities Law of 1968, as each is
now in force or hereafter amended, the Company shall be under no obligation to
issue any shares of Common Stock covered by this option unless the person who
exercises such option, in whole or in part, shall give a written representation
and undertaking to the Company which is satisfactory in form and scope to
counsel to the Company and upon which, in the opinion of such counsel, the
Company may reasonably rely, that he or she is acquiring the shares of Common
Stock issued to him or her pursuant to such exercise of this option for his or
her own account as an investment and not with a view to, or for sale in
connection with, the distribution of any such shares of Common Stock, and that
he or she will make no transfer of the same except in compliance with any rules
and regulations in force at the time of such transfer under the Securities Act
of 1933, the California Corporate Securities Law of 1968, or any other
applicable law, and that if shares of Common Stock are issued without such
registration or qualification, a legend to this effect shall be endorsed upon
the securities so issued.

           17. Section 16 hereof notwithstanding, in the event the Optionee
sells or otherwise disposes of any of the shares that may be acquired hereunder
within two (2) years of the date hereof or within one (1) year of the date such
shares are acquired hereunder, the Optionee agrees to notify the Company in
writing within ten (10) days of the date of such sale or other disposition of
the number of shares sold or disposed of, the nature of the transaction, and the
amount received (if any) upon such sale or other disposition. The Optionee
understands that such a sale or other disposition may result in imposition of
withholding taxes, and agrees to remit to the Company on request any amounts
requested to satisfy any withholding tax liability.

           18. The Optionee agrees to notify in writing the Corporate Secretary
of the Company of his or her intention, if any, to terminate his or her
employment within ten (10) days after said intention is formed.

           19. Subject to any employment contract with the Optionee, the terms
of employment of the Optionee shall be determined from time to time by the Bank
and the Bank shall have the right, which is hereby expressly reserved, to
terminate the employee or change the terms of the employment at any time for any
reason whatsoever, with or without good cause.

           20. Whenever shares of Common Stock are to be issued to the Optionee
in satisfaction of the rights conferred hereby, the Company shall have the right
to require the

                                       9
<PAGE>
 
Optionee to remit to the Company an amount sufficient to satisfy federal, state
and local withholding tax requirements prior to the delivery of any certificate
or certificates for such shares. Whenever the Optionee is required to pay to the
Company an amount required to be withheld under applicable federal and state
income tax laws in connection with receipt of shares of Common Stock upon
exercise of this option, the Committee may, in its absolute discretion, permit
the Optionee to satisfy such obligation, in whole or in part, by electing to
have the Company withhold shares of Common Stock having a value equal to the
amount required to be withheld or by delivering to the Company already-owned
shares to satisfy the withholding requirement. The amount of the withholding
requirement shall include any amount agreed to be withheld at the time the
election is made, not in excess of the maximum federal and state income tax.
rates applicable to the Optionee on the date that the amount of tax to be
withheld is to be determined (the "Tax Date"). The value of the shares to be
withheld or delivered will be based on their Fair Market Value on the Tax Date.
Such elections will be subject to the following restrictions: (1) the election
must be made on or before the Tax Date; (2) the election will be irrevocable;
and (3) the election will be subject to the disapproval of the Committee. Each
election by an optionee whose transactions in shares of Common Stock are subject
to Section 16(b) of the Securities Exchange Act of 1934 will be subject to the
following additional restrictions: (1) the election may not be made within six
(6) months of the grant of this option (except that this limitation will not
apply in the event death or disability of the optionee occurs prior to the
expiration of the six-month period), and (2) the election must be made either at
least six (6) months before the Tax Date or within a ten (10) day period
beginning on the third day following the release of the Company's quarterly or
annual summary statement of earnings.

           21. The Committee shall have the power to interpret the Plan and this
Agreement and to adopt such rules for the administration, interpretation and
application of the Plan as are consistent therewith and to interpret or revoke
any such rules. All actions taken and all interpretations and determinations
made by the Committee in good faith shall be final and binding upon Optionee,
the Company and all other interested persons. No member of the Board of
Directors or of the Committee shall be personally liable for any action,
determination or interpretation made in good faith with respect to the Plan or
this Agreement.

           22. In the event that any provision of this Agreement shall be
invalid or unenforceable, such provision shall be severable from, and such
invalidity or

                                       10
<PAGE>
 
 unenforceability shall not be construed to have any effect on, the remaining
 provisions of this Agreement.

           IN WITNESS HEREOF, the parties hereto have executed this Agreement,
 in duplicate, the day and year first above written.
