                                DECEMBER 9, 1996
    
 
Dear Shareholder:
 
   
    You are cordially invited to attend a Special Meeting of Shareholders (the
"Special Meeting") of Ventura County National Bancorp ("Ventura") on Tuesday,
January 14, 1997, at 5:30 p.m., which will be held at Ventura's offices at 500
Esplanade Drive, Oxnard, California.
    
 
    At the Special Meeting, you will be asked to consider and vote upon a
proposal to approve the Agreement and Plan of Merger (the "Merger Agreement")
pursuant to which Ventura would be merged into City National Corporation ("City
National"). The enclosed Proxy Statement/Prospectus more fully describes the
proposed merger, including information about Ventura and City National.
 
    Under the terms of the Merger Agreement, and subject to certain allocation
procedures designed to ensure that 55% of the outstanding common stock, no par
value, of Ventura ("Ventura Stock") is converted into common stock, $1.00 par
value, of City National ("City National Stock") and 45% of the outstanding
Ventura Stock is converted into cash, each outstanding share of Ventura Stock
would be converted into, at the election of the holder, cash, City National
Stock, or a combination of the two. Holders receiving cash will receive $5.03
for each share of Ventura Stock held by them. Holders receiving City National
Stock will receive for each share of Ventura Stock held by them, that fraction
of a share of City National Stock (the "Exchange Ratio") determined by dividing
$5.03 by the average closing price per share of City National Stock for the 20
consecutive trading days ending on the third trading day immediately prior to
consummation of the Merger (the "Final City National Stock Price"); provided, in
the event the Final City National Stock Price is more than $19.10, the Exchange
Ratio will be based upon a Final City National Stock Price of $19.10 and,
accordingly, will be fixed at .2634, and in the event the Final City National
Stock Price is less than $15.65, the Exchange Ratio will be based upon a Final
City National Stock Price of $15.65, and, accordingly, will be fixed at .3214.
 
    The Board of Directors of Ventura has carefully considered the terms and
conditions of the Merger Agreement and the proposed merger with City National.
THE BOARD OF DIRECTORS BELIEVES THE PROPOSED MERGER IS IN THE BEST INTERESTS OF
VENTURA COUNTY NATIONAL BANCORP AND ITS SHAREHOLDERS AND UNANIMOUSLY RECOMMENDS
THAT YOU VOTE FOR ITS APPROVAL.
 
    We urge you to read carefully the enclosed Notice of Special Meeting and
Proxy Statement/Prospectus which more fully describe the terms of the Merger
Agreement and the proposed merger.
 
   
    It is important that your shares be represented at the Special Meeting,
whether or not you plan to attend in person. Therefore, you should complete,
sign and date the enclosed proxy card and return it as soon as possible in the
enclosed postage-paid envelope so that your shares will be represented at the
Special Meeting. If you attend the Special Meeting, you may vote in person if
you wish, even if you have previously returned a proxy card.
    
 
   
    If you have any questions regarding the Special Meeting or the proposed
merger, you are encouraged to call Georgeson & Company, Inc., which is acting as
proxy solicitor and information agent for this transaction, toll-free at (800)
223-2064.
    
 
    We look forward to seeing you at this important Special Meeting.

                           CITY NATIONAL CORPORATION
 
                                  COMMON STOCK
 
                          (PAR VALUE $1.00 PER SHARE)
                             ---------------------
 
   
    This Proxy Statement/Prospectus is being furnished to the holders of common
stock, no par value ("Ventura Stock") of Ventura County National Bancorp, a
California corporation ("Ventura"), in connection with the solicitation of
proxies by the Board of Directors of Ventura for use at the special meeting of
Ventura's shareholders to be held at Ventura's offices at 500 Esplanade Drive,
Oxnard, California, on Tuesday, January 14, 1997, at 5:30 p.m., Pacific Standard
Time, and at any adjournments or postponements thereof (the "Special Meeting").
    
 
    At the Special Meeting, the shareholders of record of Ventura Stock as of
the close of business on November 25, 1996 will consider and vote upon a
proposal to approve that certain Agreement and Plan of Merger, dated as of
September 15, 1996 (the "Merger Agreement"), by and between City National
Corporation, a Delaware corporation ("City National"), and Ventura pursuant to
which Ventura will merge with and into City National (the "Merger"). See "THE
SPECIAL MEETING." Upon consummation of the Merger, each outstanding share of
Ventura Stock (except for shares held by Ventura shareholders properly
exercising dissenters' rights and shares held by CNC or VCNB) will be converted
into the right to receive either (1) $5.03 in cash; (2) shares of common stock
of City National, par value $1.00 per share ("City National Stock") calculated
as described in this Proxy Statement/Prospectus; or (3) a combination of cash
and City National Stock calculated as described in this Proxy
Statement/Prospectus, and holders of Ventura Stock will be given the opportunity
to indicate the form of consideration they prefer. See "THE
MERGER--Consideration Payable Upon Consummation of the Merger." Pursuant to the
Merger Agreement, 55% of the aggregate number of issued and outstanding shares
of Ventura Stock (the "Stock Amount") as of the Effective Time (as hereinafter
defined) will be converted into shares of City National Stock. In the event that
holders of Ventura Stock elect, in the aggregate, to convert more or less than
the Stock Amount into shares of City National Stock, certain holders of Ventura
Stock will receive a prorated number of shares of City National Stock and a
prorated amount of cash such that a number of shares of Ventura Stock
approximately equal to the Stock Amount is converted into shares of City
National Stock. The fraction of a share of City National Stock into which each
share of Ventura Stock for which an effective Stock Election or Combination
Election (each as hereinafter defined) is made will be converted in the Merger
cannot be determined until the Election Deadline. See "THE MERGER." The Merger
Agreement is included as Appendix A to this Proxy Statement/Prospectus. Subject
to regulatory approval, the shareholder approval being sought at the Special
Meeting and satisfaction or waiver of the other conditions described herein, the
Merger currently is expected to be consummated during the first quarter of 1997.
 
    This Proxy Statement/Prospectus also constitutes a prospectus of City
National in respect of up to 1,743,787 shares of City National Stock to be
issued upon consummation of the Merger pursuant to the Merger Agreement.
 
   
    The outstanding shares of City National Stock are listed on the New York
Stock Exchange ("NYSE"). The last reported sale price of City National Stock on
the NYSE Composite Transactions Tape on December 3, 1996 was $20.625 per share.

accompanying proxy card are first being mailed to shareholders of Ventura on or
about December 9, 1996.

<PAGE>
               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
 
   
    Certain matters discussed in this Proxy Statement/Prospectus and the
documents incorporated herein by reference may constitute forward-looking
statements within the meaning of the Private Litigation Reform Act of 1995 and
as such may involve known and unknown risks, uncertainties, and other factors
which may cause the actual results, performance, or achievements of City
National and/or Ventura to be materially different from any future results,
performance, or achievements expressed or implied by such forward-looking
statements. Specifically, City National and Ventura caution readers that the
following important factors could affect City National's and/or Ventura's
respective businesses and cause actual results to differ materially from those
expressed in any forward-looking statement made by, or on behalf of, City
National or Ventura in this Proxy Statement/Prospectus:
    
 
   
        (1) Economic Conditions.  City National's and Ventura's respective
    results are strongly influenced by general economic conditions in their
    respective market areas. Accordingly, a deterioration in these conditions
    could have a material adverse impact on the quality of City National's or
    Ventura's loan portfolio and the demand for their products and services. In
    particular, changes in economic conditions in the real estate and, with
    respect to City National only, entertainment industries may affect their
    performance.
    
 
   
        (2) Interest Rates.  City National and Ventura anticipate that interest
    rate levels will remain generally constant in 1997, but if interest rates
    vary substantially from present levels, City National's and/or Ventura's
    results may differ materially from the results currently anticipated.
    
 
   
        (3) Government Regulation and Monetary Policy.  All forward-looking
    statements presume a continuation of the existing regulatory environment and
    United States government monetary policies. The banking industry is subject
    to extensive federal and state regulations, and significant new laws or
    changes in, or repeals of, existing laws may cause results to differ
    materially. Further, federal monetary policy, particularly as implemented
    through the Federal Reserve System, significantly affects credit conditions
    for City National and Ventura, primarily through open market operations in
    United States government securities, the discount rate for member bank
    borrowings and bank reserve requirements, and a material change in these
    conditions would be likely to have a material impact on City National's
    and/or Ventura's results.
    
 
   
        (4) Competition.  City National and Ventura compete with numerous other
    domestic and foreign financial institutions and non-depository financial
    intermediaries. Results of City National and/or Ventura may differ if
    circumstances affecting the nature or level of competition change, such as
    the merger of competing financial institutions or the acquisition of
    California institutions by out-of-state companies.
    
 
   
        (5) Credit Quality.  A significant source of risk arises from the
    possibility that losses will be sustained because borrowers, guarantors and
    related parties may fail to perform in accordance with the terms of their
    loans. City National and Ventura have adopted underwriting and credit
    monitoring procedures and credit policies, including the establishment and
    review of the allowance for credit losses, that their respective managements
    believe are appropriate to minimize this risk by assessing the likelihood of
    nonperformance, tracking loan performance and diversifying City National's
    and Ventura's respective credit portfolios, but such policies and procedures
    may not prevent unexpected losses that could materially adversely affect
    City National's and/or Ventura's results.
    
 
   
        (6) Other Risks.  From time to time, City National and Ventura detail
    other risks with respect to their respective businesses and/or their
    financial results in their respective filings with the Securities and
    Exchange Commission (the "SEC") and the Office of the Comptroller of the
    Currency (the "OCC") respectively.
    
 
   
    While management of City National and Ventura believe that their respective
assumptions regarding these and other factors on which forward-looking
statements are based are reasonable, such assumptions are necessarily
speculative in nature, and actual outcomes can be expected to differ to some
degree.
    
 
                                       2

Consequently, there can be no assurance that the results described in such
forward-looking statements will, in fact, be achieved.
    
 
                             AVAILABLE INFORMATION

EFFECT OF THE MERGER
 
    Pursuant to the Merger Agreement, at the Effective Time (see "THE

Merger." For information on how Ventura shareholders will be able to
 
                                       10
<PAGE>
exchange certificates representing shares of Ventura Stock for new certificates
representing shares of City National Stock (and cash in lieu of fractional
shares), and/or cash to be issued to them, see "THE MERGER--Surrender of Ventura
Stock Certificates."
 
    Immediately following the Merger, City National may cause Ventura Bank and
Frontier Bank to merge with and into City National Bank, a wholly owned
subsidiary of City National. See "THE MERGER--Bank Mergers."
 
CONSIDERATION PAYABLE UPON CONSUMMATION OF THE MERGER
 
    In the aggregate, 55% of the shares of Ventura Stock issued and outstanding
immediately prior to the Effective Time (other than "Dissenting Shares" and
"Cancelled Shares" (each as defined below)) will be converted into the right to
receive City National Stock and 45% of such shares of Ventura Stock will be
converted into the right to receive cash. Holders of Ventura Stock will have the
opportunity to indicate their preference for receiving a different proportion of
cash and City National Stock in the Merger, and may indicate a preference for
receiving all cash or all City National Stock. Such elections will be honored to
the extent possible, provided that the Merger consideration in the aggregate
will remain 55% City National Stock and 45% cash. As used in this Proxy
Statement/Prospectus, (i) "Dissenting Shares" means shares which have not been
voted in favor of approval of the Merger Agreement and with respect to which
dissenters' rights have been perfected in accordance with California law and
(ii) "Cancelled Shares" means shares of Ventura Stock that may be owned by
Ventura (or any of its wholly owned subsidiaries) as treasury stock or owned by
City National (or any of its wholly owned subsidiaries) other than shares held
in a fiduciary capacity or in satisfaction of a debt previously contracted.
 
    Each such share of Ventura Stock will, by virtue of the Merger, be converted
into the right to receive either: (i) a fraction of a share of City National
Stock equal to the quotient (such quotient, the "Exchange Ratio") of (a) $5.03,
divided by (b) the average of the daily closing prices of a share of City
National Stock on the NYSE as reported in the WALL STREET JOURNAL for the twenty
consecutive trading days ending on the third trading day immediately prior to
the Effective Time (such average, the "Final City National Stock Price");
provided, however, that if the Final City National Stock Price is more than
$19.10, the Exchange Ratio will be based upon a Final City National Stock Price
of $19.10 and, accordingly, will be fixed at 0.2634, and if the Final City
National Stock Price is less than $15.65, the Exchange Ratio will be based upon
a Final City National Stock Price of $15.65 and, accordingly, will be fixed at
0.3214; (ii) cash in the amount of $5.03; or (iii) a combination of City
National Stock (at the rate of the Exchange Ratio for a whole share of Ventura
Stock) and cash (at the rate of $5.03 for a whole share of Ventura Stock).
 
    In the event that holders of Ventura Stock elect, in the aggregate, to
convert more or less than the Stock Amount into shares of City National Stock,
certain holders of Ventura Stock will receive a prorated number of shares of
City National Stock and a prorated amount of cash such that a number of shares
of Ventura Stock approximately equal to the Stock Amount is converted into
shares of City National Stock. The fraction of a share of City National Stock
into which each share of Ventura Stock for which an effective "Stock Election"
or "Combination Election" (each as hereinafter defined) is made will be
converted in the Merger cannot be determined until the Effective Time.
 
    See "THE MERGER--Consideration Payable Upon Consummation of the Merger."

OPINION OF FINANCIAL ADVISOR
 
   
    Sandler O'Neill & Partners, L.P. ("Sandler O'Neill") has served as financial
advisor to Ventura in connection with the Merger, and has delivered a written
opinion to the Ventura Board of Directors that, as of September 15, 1996, the
aggregate consideration to be paid to Ventura's shareholders as a result of the
Merger is fair from a financial point of view. Sandler O'Neill also delivered to
the Ventura Board of Directors on December 4, 1996 a written confirmation of the
September 15, 1996 written opinion. For additional information, see "THE
MERGER--Opinion of Financial Advisor to Ventura." The opinion of Sandler O'Neill
dated December 4, 1996, is attached as Appendix E to this Proxy
Statement/Prospectus. Shareholders are urged to read such opinion in its
entirety for descriptions of the procedures followed, matters considered and
limitations on the reviews undertaken, in connection therewith.
    
 
EFFECTIVE TIME
 
   
    The Merger will become effective when certain filings are made with the
Secretary of State of the State of Delaware. Such filings will be made on the
first Friday (unless such date is a holiday, in which case it will be the
preceding business day) that is both (a) after satisfaction of each of the
conditions set forth in Article VII of the Merger Agreement (see "THE MERGER --
Conditions to Consummation of the Merger") and (b) no less than four business
days after the occurrence of the Election Deadline (as hereinafter defined). The
parties anticipate that they may waive the four business day waiting period.
    
 
    If the Merger is approved by the shareholders of Ventura, subject to certain
conditions described herein, the Effective Time is currently expected to occur
in the first quarter of 1997.
 
CONDITIONS; REGULATORY APPROVALS
 
    Consummation of the Merger is subject to various conditions, including (i)
receipt of the shareholder approval solicited hereby, (ii) receipt of the
necessary regulatory approvals, (iii) that at the close of business on the last
day of the month preceding the Effective Time, the Book Value Per Share (as
defined in Section 7.2(e) of the Merger Agreement) of Ventura shall be not less
than $3.12; (iv) that at the close of business on the last day of the month
preceding the Effective Time, total deposits of Ventura and its subsidiaries
shall be not less than 85% of the average of total deposits for Ventura and its
subsidiaries for the six month period ending on the last day of the same month
in the preceding year; (v) receipt of certain opinions of counsel regarding,
among other matters, certain tax aspects of the Merger and (vi) satisfaction of
other closing conditions.
 
   
    The Merger is subject to approval by the Board of Governors of the Federal
Reserve System, which approval was received by City National on December 3,
1996.
    
 
    See "THE MERGER--Conditions to Consummation of the Merger," "--Regulatory
Approvals," and "--Conduct of Business Pending the Merger."
 
CONDUCT OF BUSINESS PENDING MERGER
 
    VENTURA.  The Merger Agreement contains certain restrictions on the conduct
of Ventura's business prior to the Effective Date. Certain purposes of these
restrictions are (1) to ensure that Ventura is in substantially the same
condition at the Effective Time as it was in on September 15, 1996, the date of
the
 
                                       12
<PAGE>
Merger Agreement, (ii) to ensure that the Effective Time is not unnecessarily
delayed and (iii) to preserve the status of the Merger as a reorganization
within the meaning of Section 368(c) of the Internal Revenue Code of 1986, as
amended (the "Code").
 
    CITY NATIONAL.  The Merger Agreement also contains certain restrictions on
the conduct of City National's business prior to the Effective Time. Certain
purposes of these restrictions are to ensure (i) that City National does not
impair the value of City National Stock and (ii) that the Effective Date is not
unnecessarily delayed.
 
    See "THE MERGER--Conduct of Business Pending the Merger."
 
TERMINATION OF THE MERGER AGREEMENT
 
    The Merger Agreement may be terminated at any time prior to the Effective
Time, either before or after its approval by the shareholders of Ventura, (i) by
the mutual agreement of Ventura and City National, (ii) by Ventura if the Final
City National Stock Price is less than $13.90 or (iii) by either City National
or Ventura under certain specified circumstances, including the failure of the
Merger to be effective by May 31, 1997, unless such failure is due to the breach
of any covenant or obligation contained in the Merger Agreement by the party
seeking to terminate. See "THE MERGER--Amendment and Termination."
 
    Following the Special Meeting, in the event the Final City National Stock
Price is less than $13.90 the Ventura Board of Directors will have the
discretion, without the necessity of a further vote of the Ventura shareholders,
to determine whether or not to proceed with the Merger. In exercising such
discretion, the
Ventura Board of Directors anticipates that it would review current information
and consider a variety of factors including those which it considered in making
its initial decision to enter into the Merger Agreement. Based thereon, the
Board of Directors may determine not to exercise Ventura's right to terminate
the Merger Agreement. See "THE MERGER--Background of and Reasons for the
Merger."
 
BANK MERGER
 
    After the Effective Time, City National expects to cause Ventura Bank and/or
Frontier Bank to merge with and into City National Bank, with City National Bank
as the surviving corporation (the "Bank Merger") subject to receipt of necessary
regulatory approvals. There can be no assurance that such approvals will be
obtained or that the Bank Merger will be consummated. Upon consummation of the
Bank Merger, the directors and officers of City National Bank immediately prior
to the Bank Merger will be the directors and officers, respectively, of the
surviving corporation. See "THE MERGER--Bank Mergers."
 
RIVERSIDE MERGER
 
    City National and City National Bank are also parties to an Agreement and
Plan of Merger with Riverside National Bank ("Riverside"), dated as of October
15, 1996 (the "Riverside Agreement"), which contemplates the merger of Riverside
and City National Bank, and the issuance of City National Stock and/or cash to
shareholders of Riverside. Subject to the satisfaction of a number of
conditions, including regulatory and Riverside shareholder approval, the
Riverside Merger and the Merger are expected to be consummated within several
weeks of each other. While it is currently expected that the Merger is likely to
be consummated prior to the Riverside Merger, there is a possibility that the
Riverside Merger will be the first of the two transactions to close. As of
September 30, 1996, Riverside had total assets of $248.4 million and total
deposits of $219.4 million.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
   
    As of the Record Date, the directors and executive officers of Ventura
(including the executive officers of Ventura Bank and Frontier Bank)
beneficially owned 1,308,730 shares of Ventura Stock (not
    
 
                                       13
<PAGE>
   
including shares such persons may acquire through the exercise of vested stock
options), which will be converted into the right to receive cash or City
National Stock or both at the Effective Time in the same manner as will the
shares of Ventura Stock held by all other Ventura shareholders. In addition,
directors and executive officers of Ventura (including the executive officers of
Ventura Bank and Frontier Bank) held as of such date options to purchase 196,116
shares of Ventura Stock, which will be exercised or canceled in exchange for
certain cash payments in connection with the Merger. Immediately after the
Effective Time, former directors and executive officers of Ventura as a group
will own less than 1% of the outstanding shares of City National Stock.
    
 
    Pursuant to the terms of certain agreements for executive officers of
Ventura certain executive officers of Ventura are entitled to receive severance
payments in the event of termination of employment, as well as salary and
benefit continuation payments in the event of a termination of employment as a
result of a change in control, such as the Merger, which severance and
continuation payments aggregate approximately $1,300,000.
 
    City National has requested each of Richard Cupp, Kathleen Kellogg, Carl
Raggio and Simone Lagomarsino to remain employees of City National (or one of
its subsidiaries) for a period of up to six months following the Effective Time.
City National and the four executive officers of Ventura are currently engaged
in discussions to determine whether they can reach mutually satisfactory terms
for any such employment relationship.
 
    The Merger Agreement provides that all rights to indemnification now
existing in favor of the directors and officers of Ventura, Ventura Bank and
Frontier Bank in effect as of the date of the Merger Agreement will survive the
Merger and will continue in full force and effect. City National also agreed
that following the consummation of the Merger, to the fullest extent permitted
by Delaware law, the City National Certificate of Incorporation (the "City
National Certificate") and the City National Bylaws, it would indemnify, defend
and hold harmless individuals who were directors or officers of Ventura, Ventura
Bank or Frontier Bank for any claim or loss arising out of their actions while a
director or officer and shall pay the expenses, including attorneys' fees, of
such individual in advance of the final resolution of any claim, provided such
individual first executes an undertaking acceptable to City National to return
such advances in the event it is finally concluded that such indemnification is
not allowed under applicable law.
 
    See "THE MERGER--Interests of Certain Persons in the Merger."
 
CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
    It is intended that the Merger will be treated as a tax-deferred
reorganization within the meaning of Section 368(a) of the Code and accordingly,
for federal income tax purposes, (i) no gain or loss will be recognized by
either Ventura or City National as a result of the Merger and (ii) in general,
holders of Ventura Stock will not recognize gain or loss to the extent that they
receive City National Stock in exchange for Ventura Stock, except to the extent
of any cash received in lieu of fractional shares. Ventura has received an
opinion from Manatt, Phelps & Phillips, LLP, special counsel to Ventura ("Tax
Counsel"), confirming the tax treatment of the Merger. Consummation of the
Merger is conditioned upon receipt by Ventura of an updated opinion from Tax
Counsel confirming the tax treatment of the Merger. See "THE MERGER--Certain
Federal Income Tax Considerations" and "--Conditions to Consummation of the
Merger."
 
ACCOUNTING TREATMENT
 
    The Merger will be accounted for by City National under the purchase method
of accounting. See "THE MERGER--Accounting Treatment."
 
SHAREHOLDERS' AGREEMENT
 
    Each of the directors of Ventura have agreed, pursuant to a Shareholders'
Agreement, to vote all shares of Ventura Stock owned or acquired by them, in
favor of the Merger and the Merger Agreement and the other matters contemplated
by the Merger Agreement.
 
                                       14
<PAGE>
    In addition, the directors have agreed to vote their shares of Ventura Stock
against any action that would constitute a breach by Ventura of the Merger
Agreement or that could interfere with or delay the contemplated economic
benefits to City National of the Merger or the Stock Option Agreement and
against extraordinary corporate transactions, changes in the majority of the
board of Ventura or other material changes.
 
    See "CERTAIN RELATED AGREEMENTS--Shareholders' Agreement."
 
OPTION AGREEMENT
 
   
    Concurrently with the execution and delivery of the Merger Agreement, and as
a condition and inducement thereto, City National and Ventura entered into a
Stock Option Agreement, pursuant to which Ventura granted City National an
option to purchase up to 1,836,516 shares of the outstanding Ventura Stock (or
such other number of shares of Ventura Stock as shall represent 19.9% of the
then outstanding Ventura Stock) at a price per share of $3.93. The consummation
of a purchase or a repurchase pursuant to the Stock Option Agreement may be
subject to, among other things, obtaining any required regulatory approvals. See
"CERTAIN RELATED AGREEMENTS--Option Agreement."
    
 
DISSENTERS' RIGHTS
 
    In the event that holders of five percent (5%) or more of Ventura Stock vote
against the Merger and make a written demand upon Ventura for the purchase of
dissenting shares in accordance with the provisions of Chapter 13 of the
California General Corporation Law ("California Code"), such holders will be
entitled to receive an amount equal to the fair market value of their shares as
of September 13, 1996, the last trading day before the public announcement of
the Merger. See "DISSENTER'S RIGHTS-- Rights of Dissenting Shareholders."
 
CERTAIN DIFFERENCES IN SHAREHOLDERS' RIGHTS
 
    Ventura shareholders' rights are currently governed by California law, the
Ventura Articles of Incorporation (the "Ventura Articles") and the Ventura
By-laws. Upon consummation of the Merger, shareholders of Ventura Stock
receiving City National Stock will become stockholders of City National and
their rights as such will be governed by Delaware law, the City National
Certificate and the City National By-laws. See "COMPARISON OF RIGHTS OF HOLDERS
OF CITY NATIONAL STOCK AND VENTURA STOCK."
 
MARKETS AND MARKET PRICES
 
   
    The City National Stock is listed on the NYSE under the symbol "CYN" and the
Ventura Stock is quoted in the Nasdaq National Market System under the symbol
"VCNB." The closing price per share of City National Stock, as reported on the

SELECTED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION
 
   
    The following tables present selected pro forma condensed combined financial
data as of September 30, 1996 and for the year ended December 31, 1995 and for
the nine months ended September 30, 1996 as if the Merger and the Riverside
Merger had been effective on January 1, 1995 and January 1, 1996, respectively,
after giving effect to the purchase accounting and other merger-related
adjustments described in the respective Notes to Pro Forma Condensed Combined
Financial Statement. See "PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION."
The Low Range, Medium Range and High Range selected pro forma condensed combined
financial data, respectively, reflect the Ventura Merger being completed at an
assumed Final City National Stock Price equal to $13.90 per share, $17.475 per
share, and $19.10 per share with respect to the Merger and $13.50 per share,
$17.475 per share and $19.50 per share with respect to the Riverside Merger.
Actual results within each of the Low, Medium and High Ranges will vary from
those presented if the Final City National Stock Price is other than those
assumed in the tables. See "THE MERGER--Consideration Payable Upon Consummation
of the Merger". The selected pro forma condensed combined financial information
tables are intended for illustrative purposes only and are not necessarily
indicative of the future financial positions or future results of operations of
City National after (i) the Merger or (ii) the Merger and the Riverside Merger
or of the financial position or results of operations that would have actually
occurred had (a) the Merger or (b) the Merger and the Riverside Merger been in
effect as of the dates or the periods presented.

    The following unaudited financial information reflects certain comparative
per share data relating to net income, cash dividends, and book value per common
share (1) on a historical basis for City National and Ventura, (2) on a pro
forma combined basis per share of City National Stock giving effect to the
Merger, (3) on a pro forma combined basis per share of City National Stock
giving effect to both the Merger and the Riverside Merger and (4) on an
equivalent pro forma basis per share of Ventura Stock giving effect to the
Merger and the Riverside Merger. The pro forma combined information and the
Ventura pro forma equivalent information give effect to the Merger and the
Riverside Merger on a purchase accounting basis and reflect the Low Range,
Medium Range and High Range assumed for the Final City National Stock Price as
discussed in the Pro Forma Condensed Combined Financial Information. There can
be no assurance as to what the market price of the City National Stock will be
if and when the Merger and the Riverside Merger are consummated. See
"INTRODUCTION--Markets and Market Prices." For a description of purchase
accounting with respect to the Merger, see "THE MERGER-- Accounting Treatment
and "PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION." The information shown
below is for information purposes only and should be read in conjunction with
the historical consolidated financial statements of Ventura and City National,
including the respective notes thereto, which, in the case of Ventura, appear as
an Appendix to this Proxy Statement/Prospectus, and in the case of City
National, are incorporated by reference in this Proxy Statement/Prospectus, and
the unaudited pro forma financial statements, including the notes thereto,
included in this Proxy Statement/ Prospectus. Results of Ventura and City
National for the nine months ended September 30, 1996 are not necessarily
indicative of the results which may be expected for any other interim period or
for the year as a whole. The pro forma financial data are not necessarily
indicative of results that actually would have occurred had the Merger and/or
the Riverside Merger been consummated on the date indicated or that may be
obtained in the future. See "INCORPORATION OF CERTAIN INFORMATION BY REFERENCE."

Ratio is determined by dividing $5.03 by the Final City National Stock Price,
provided in the event the Final City National Stock Price is more than $19.10,
the Exchange Ratio will be based upon a Final City National Stock Price of
$19.10 and, accordingly, will be fixed at .2634 (the "High Range") and in the
event the Final City National Stock Price is less than $15.65, the Exchange
Ratio will be based upon a Final City National Stock Price of $15.65 and,
accordingly, will be fixed at .3214. Ventura has the right to terminate the
Merger if the Final City National Stock Price is less than $13.90 (the "Low
Range"). The exchange ratio based on the average of the closing City National
Stock prices on the twenty business days ending three business days before
September 30, 1996 was .2878 (the "Medium Range"). Pursuant to the Merger
Agreement, 55% of the aggregate number of issued and outstanding shares of
Ventura Stock as of the Effective Time will be converted into shares of City
National Stock.
 
    The Low Range Pro Forma Condensed Combined Financial Statements reflect the
purchase being completed at a Final City National Stock Price of $13.90 and an
Exchange Ratio of .3214. If the Final City National Stock Price was below $13.90
per share, Ventura would have the right to terminate the Merger Agreement,
without payment of consideration. Accordingly, this Low Range scenario reflects
the lowest consideration received by those Ventura shareholders who receive City
National Stock and the lowest purchase price payable prior to Ventura having a
unilateral right to terminate the Merger Agreement. However, if the Ventura
Board of Directors does not exercise its right to terminate the Merger Agreement
in the event that the Final City National Stock Price Falls below $13.90 per
share, the purchase price payable to the Ventura shareholders will be lower. See
"THE MERGER--Amendment and Termination."
 
    The Medium Range Pro Forma Condensed Combined Financial Statements reflect
the purchase being completed at a Final City National Stock Price of $17.475 and
an Exchange Ratio of .2878.
 
    At a Final City National Stock Price above $19.10, the consideration
received by Ventura shareholders who receive City National Stock and the
purchase price would continue to increase. The High Range Pro Forma Condensed
Combined Financial Statements reflect the purchase being completed at a Final
City National Stock Price of $19.10 and an Exchange Ratio of .2634 which results
in the lowest purchase price payable within the High Range.
 
    Under the Riverside Agreement, Riverside shareholders receiving City
National Stock will receive for each share of Riverside Stock held by them, that
fraction of a share (or number of shares) of City National Stock (the "Riverside
Exchange Ratio") determined by dividing $18.00 by the Final City National Stock
Price for Riverside, provided in the event the Final City National Stock Price
for Riverside is between $19.50 and $22.50, the Riverside Exchange Ratio will be
based upon a Final City National Stock Price for Riverside of $19.50 and,
accordingly, will be fixed at .9231 (the "Riverside High Range"). In the event
the Final City National Stock Price is above $22.50, the Riverside Exchange
Ratio is determined by dividing $20.77 by the Final City National Stock Price.
In the event the Final City National Stock Price for Riverside is less than
$16.00, the Riverside Exchange Ratio will be based upon a Final City National
Stock Price of $16.00 and, accordingly, will be fixed at 1.125. Riverside has
the right to terminate the Riverside

Merger if the Final City National Stock Price for Riverside is less than $13.50
and the number obtained by dividing the Final City National Stock Price for
Riverside by $17.75 is more than 15% less than the number obtained by dividing
the average closing price of the banks and bank holding companies included in
the Standards & Poor's Bank Index for the twenty consecutive business days
ending three days prior to the Riverside closing by the Index Price on October
10, 1996 (the "Riverside Low Range"). The Riverside Exchange Ratio based on the
average of the closing City National Stock prices on the twenty business days
ending three business days before September 30, 1996 was 1.03 (the "Riverside
Medium Range"). Pursuant to the Riverside Agreement, not less than 48% of the
aggregate number of issued and outstanding shares of Riverside common stock as
of the effective time for the Riverside Merger will be converted into shares of
City National Stock.
 
    The Low Range Pro Forma Condensed Combined Financial Statements reflect the
purchase being completed at a Final City National Stock Price of $13.50 and a
Riverside Exchange Ratio of 1.125. If the Final City National Stock Price for
Riverside was below $13.50 per share and the Standard & Poor's Bank Index had
declined by more than 15% from its level on October 10, 1996, Riverside would
have the right to terminate the Riverside Agreement, without consideration.
Accordingly, this Low Range scenario reflects the lowest consideration received
by those Riverside shareholders who receive City National Stock and the lowest
purchase price payable prior to Riverside having a unilateral right to terminate
the Riverside Agreement.
 
    The Medium Range Pro Forma Condensed Combined Financial Statements reflect
the purchase being completed at a Final City National Stock Price of $17.475 and
a Riverside Exchange Ratio of 1.03.
 
    At a Final City National Stock Price above $19.50, the consideration
received by Riverside shareholders who receive City National Stock and the
purchase price continue to increase to a maximum $22.50, above which the
purchase price is fixed. The High Range Pro Forma Condensed Combined Financial
Statements reflect the purchase being completed at a Final City National Stock
Price of $19.50 a share and a Riverside Exchange Ratio of .9231 which results in
the lowest purchase price payable in the High Range.
 
    Actual results within each of the Low, Medium and High Ranges for Ventura
and for Riverside will vary from those presented if the Final City National
Stock Price is other than those described above.
 
    The sets of unaudited pro forma combined financial statements and
accompanying notes reflect the application of the purchase method of accounting.
Under this method of accounting, the purchase price will be allocated to the
assets acquired and liabilities assumed based on their estimated fair values at
the closing. As described in the accompanying notes, estimates of the fair
values of Ventura's and Riverside's assets and liabilities have been combined
with the recorded values of the assets and liabilities of City National.
However, changes to the adjustments included in the unaudited pro forma combined
financial statements are expected as evaluations of assets and liabilities are
completed and as additional information becomes available. See "THE
MERGER--Accounting Treatment." In addition, the results of operations of Ventura
and Riverside subsequent to September 30, 1996 will affect the allocation of the
purchase price. Accordingly, the final pro forma combined amounts will differ
from those set forth in the unaudited pro forma combined financial statements.
 
    The sets of unaudited pro forma condensed combined financial statements are
intended for informational purposes only and are not necessarily indicative of
the future financial position or future results of operations of the combined
company, or of the financial position or results of operations of the combined
company that would have actually occurred had the Merger and the Riverside
Merger been in effect as of the date or for the periods presented. The unaudited
pro forma condensed combined financial statements of City National, Ventura and
Riverside should be read in conjunction with the historical and other pro forma
information, including the respective notes thereto, which in the case of City
National, are incorporated by reference in this Proxy Statement/Prospectus, and
in the case of Ventura, are attached to this Proxy Statement/Prospectus.

VENTURA
 
    BALANCE SHEET
 
    Assuming a Final City National Stock Price of $13.90, the total
consideration value paid to existing Ventura shareholders is $43,505,000, with
total cash consideration of $20,889,000 and the balance in City National Stock.
 
    The cash payment of $20,889,000 will be paid from Federal funds sold. The
number of shares to be tendered will be contingent upon the Final City National
Stock Price which is the average of the City National Stock closing price in the
twenty business day period ending three business days before the Effective Time.
For the purpose of the Low Range Pro Forma Financial Statements, the stock
portion of the total consideration value is satisfied by the issuance of
1,631,374 shares of City National Stock held as treasury stock and recorded as a
credit to shareholders' equity of $1,321,000 and to treasury shares of
$21,354,000 based on the weighted average cost of the treasury shares.
 
   
    The purchase price of $44,747,000 which includes expenses of $600,000
directly attributable to the acquisition and a $582,000 payment to cash out
existing unexercised stock options is allocated to the assets acquired and the
liabilities assumed based on their estimated fair values at September 30, 1996
in accordance with Accounting Principles Board Opinion No. 16, "Business
Combinations," as amended ("APB No. 16"). The table below reflects the
adjustment of certain assets and liabilities to estimated fair value and the
resultant goodwill. Total goodwill of approximately $8,232,000 is expected to be
amortized over ten years. Total core deposit intangibles of $14,400,000 is
expected to be amortized over seven years.

STATEMENT OF INCOME
 
   
    (a) Decrease in interest on Federal funds sold is due to the utilization of
Federal funds sold to fund the cash portion of the purchase price. The loss in
interest income is estimated to be $871,000 and $1,260,000 for the nine-month
and 12-month periods beginning January 1, 1996 and January 1, 1995,
respectively.

    (b) Non-interest expense includes the amortization of core deposit
intangibles and goodwill for the nine months beginning January 1, 1996 of
$1,543,000 and $617,000, respectively and for the 12-month period beginning
January 1, 1995 of $2,046,000 and $823,000, respectively.

tax attributes of Ventura will carry over to City National including all assets
and liabilities and are recorded at amounts previously reflected, adjusted for
purchase price allocations.
    
 
    (d) The pro forma combined net income per common share data are based on (i)
combined historical income of Ventura and City National assuming the Merger is
accounted for as a purchase and (ii) pro forma combined equivalent of the
Ventura Stock converted (as adjusted for an exchange ratio of .3214 of a share
of City National Stock for each share of Ventura Stock) and City National Common
Stock as of September 30, 1996 and December 31, 1995.
 
RIVERSIDE
 
    BALANCE SHEET
 
   
    Assuming a Final City National Stock Price for Riverside of $13.50, the
total consideration value paid to existing Riverside shareholders is
$36,202,000, with total cash consideration of $20,351,000 and the balance in
City National Stock.
    
 
   
    The cash payment of $20,351,000 will be paid from Federal funds sold. The
number of shares to be tendered will be contingent upon the Final City National
Stock Price for Riverside which is the average of the City National Stock
closing price in the twenty day period ending three business days before the
effective time of the Riverside Merger. For the purpose of the Low Range Pro
Forma Financial Statements, the stock portion of the total consideration value
is comprised of the issuance of the remaining 579,826 shares of City National
Stock held as treasury stock as of September 30, 1996 and the purchase of an
additional 594,284 shares of City National Stock on the open market for issuance
to Riverside shareholders. The issuance of the treasury stock is recorded as a
credit to shareholders' equity of $238,000 and a credit to treasury stock of
$7,590,000 based on the weighted average cost of the treasury shares. The
purchase of additional treasury shares is assumed to be at $13.50, the lowest
purchase price payable prior to Riverside having an unilateral right to
terminate the Riverside Agreement, and is assumed to be funded from liquidation
of Federal funds sold.
    
 
   
    The purchase price of $38,268,000 which includes expenses of $400,000
directly attributable to the acquisition and a $1,666,000 payment to cash out
existing unexercised stock options is allocated to the assets acquired and the
liabilities assumed based on their estimated fair values at September 30, 1996
in accordance with APB No. 16. The table below reflects the adjustment of
certain assets and liabilities to estimated fair value and the resultant
goodwill. Total goodwill of approximately $8,941,000 is expected to be amortized
over ten years. Total core deposit intangibles of approximately $12,300,000 is
expected to be amortized over seven years.

VENTURA
 
    BALANCE SHEET
 
    Assuming a Final City National Stock price of $17.475, the total
consideration value paid to Ventura shareholders is $46,420,000, with total cash
consideration of $20,889,000 and the balance in City National Stock.
 
    The cash payment of $20,889,000 will be paid from Federal funds sold. The
number of shares to be tendered will be contingent upon the Final City National
Stock Price which is the average of the City National Stock closing price in the
twenty business day period ending three business days before the Effective Time.
For the purpose of the Medium Range Pro Forma Financial Statements, the stock
portion of the total consideration value is satisfied by the issuance of
1,461,001 shares of City National Stock held as treasury stock and recorded as a
credit to shareholders' equity of $6,407,000 and to treasury shares of
$19,124,000 based on the weighted average cost of the treasury shares.
 
   
    The purchase price of $47,602,000 which includes expenses of $600,000
directly attributable to the acquisition and a $582,000 payment to cash out
existing unexercised stock options is allocated to the assets acquired and the
liabilities assumed based on their estimated fair values at September 30, 1996
in accordance with APB No. 16. The table below reflects the adjustment of
certain assets and liabilities to estimated fair value and the resultant
goodwill. Total goodwill of approximately $11,087,000 is expected to be
amortized over ten years. Total core deposit intangibles of $14,400,000 is
expected to be amortized over seven years.

VENTURA
 
    BALANCE SHEET
 
    Assuming a Final City National Stock price of $19.10, the total
consideration value paid to existing Ventura shareholders is $46,420,000, with
total cash consideration of $20,889,000 and the balance in City National Stock.
 
    The cash payment of $20,889,000 will be paid from Federal funds sold. The
number of shares to be tendered will be contingent upon the Final City National
Stock Price which is the average of the City National Stock closing price in the
twenty business day period ending three business days before the Effective Time.
For the purpose of the High Range Pro Forma Financial Statements, the stock
portion of the total consideration value is satisfied by the issuance of
1,336,702 shares of City National Stock held as treasury stock and recorded as a
credit to shareholders' equity of $8,034,000 and to treasury shares of
$17,497,000 based on the weighted average cost of the treasury shares.
 
   
    The purchase price of $47,602,000 which includes expenses of $600,000
directly attributable to the acquisition and a $582,000 payment to cash out
existing unexercised stock options is allocated to the assets acquired and the
liabilities assumed based on their estimated fair values at September 30, 1996
in accordance with APB No. 16. The table below reflects the adjustment of
certain assets and liabilities to estimated fair value and the resultant
goodwill. Total goodwill of approximately $11,087,000 is expected to be
amortized over ten years. Total core deposit intangibles of $14,400,000 is
expected to be amortized over seven years.

immediately prior to the Effective Time and an additional $4,400,000 liability
incurred in connection with the termination of contracts and leases and existing
severance contracts. Included in the total adjustment to Other Liabilities is a
$2,319,000 reduction in income taxes currently payable to reflect the tax
benefit related to the $4,400,000 liability incurred, the $500,000 in fixed
asset writeoffs and the $582,000 payment made immediately prior to the Effective
Time to cash out unexercised stock options held by Ventura's employees and
directors.
 
STATEMENT OF INCOME
 
   
    (a) Decrease in interest on Federal funds sold is due to the utilization of
Federal funds sold to fund the cash portion of the purchase price. The loss in
interest income is estimated to be $871,000 and $1,260,000 for the nine-month
and 12-month periods beginning January 1, 1996 and January 1, 1995,
respectively.
    
 
                                       40
<PAGE>
   
    (b) Non-interest expense includes the amortization of core deposit
intangibles and goodwill for the nine months beginning January 1, 1996 of
$1,543,000 and $832,000 respectively and for the 12-month period beginning
January 1, 1995 of $2,046,000 and $1,109,000 respectively.
    
 
   
    (c) Additional income tax expense is computed using a 42.3% tax rate. The
tax attributes of Ventura will carry over to City National including all assets
and liabilities and are recorded at amounts previously reflected, adjusted for
purchase price allocations.
    
 
    (d) The pro forma combined net income per common share data are based on (i)
combined historical income of Ventura and City National assuming the Merger is
accounted for as a purchase and (ii) pro forma combined equivalent of the
Ventura Stock converted (as adjusted for an exchange ratio of .2634 of a share
of City National Stock for each share of Ventura Stock) and City National Stock
as of September 30, 1996 and December 31, 1995.
 
RIVERSIDE
 
    BALANCE SHEET
 
   
    Assuming a Final City National Stock Price for Riverside of $19.50, the
total consideration value paid to existing Riverside shareholders is
$39,137,000, with total cash consideration of $20,351,000 and the balance in
City National Stock.
    
 
   
    The cash payment of $20,351,000 will be paid from Federal funds sold. The
number of shares to be tendered will be contingent upon the Final City National
Stock Price for Riverside which is the average of the City National Stock
closing price in the twenty day period ending three business days before the
effective time of the Riverside Merger. For the purpose of the High Range Pro
Forma Financial Statements, the stock portion of the total consideration value
is comprised of the issuance of the remaining 874,498 shares of City National
Stock held as treasury stock as of September 30, 1996 and the purchase of an
additional 88,874 shares of City National Stock on the open market for issuance
to Riverside shareholders. The issuance of the treasury stock is recorded as a
credit to shareholders' equity of $5,606,000 and a credit to treasury stock of
$11,447,000 based on the weighted average cost of the treasury shares. The
purchase of additional treasury shares is assumed to be at $19.50, and is
assumed to be funded from liquidation of Federal funds sold.
    
 
   
    The purchase price of $41,203,000 which includes expenses of $400,000
directly attributable to the acquisition and a $1,666,000 payment to cash out
existing unexercised stock options is allocated to the assets acquired and the
liabilities assumed based on their estimated fair values at September 30, 1996
in accordance with APB No. 16. The table below reflects the adjustment of
certain assets and liabilities to estimated fair value and the resultant
goodwill. Total goodwill of approximately $11,876,000 is expected to be
amortized over ten years. Total core deposit intangibles of approximately
$12,300,000 is expected to be amortized over seven years.

STATEMENT OF INCOME
 
   
    (a) Decrease in interest on Federal funds sold is due to the utilization of
Federal funds sold to fund the cash portion of the purchase price. The loss in
interest income is estimated to be $921,000 and $1,332,000 for the nine-month
and 12-month periods beginning January 1, 1996 and January 1, 1995,
respectively.
    
 
   
    (b) Non-interest expense includes the amortization of core deposit
intangibles and goodwill for the nine months beginning January 1, 1996 of
$1,318,000 and $891,000, respectively and for the 12-month period beginning
January 1, 1995 of $1,758,000 and $1,188,000, respectively.
    
 
   
    (c) Additional income tax expense is computed using a 42.3% tax rate. The
tax attributes of Riverside will carry over to City National including all
assets and liabilities and are recorded at amounts previously reflected,
adjusted for purchase price allocations.

proposal to approve the Merger Agreement pursuant to which Ventura will merge
with and into City National and the Merger. Upon consummation of the Merger,
each outstanding share of Ventura Stock (other than Dissenting Common Stock and

to receive, at the election of the holder thereof either: (1) shares of City
National Stock calculated as described herein; (2) $5.03 in cash; or (3) a
combination of City National Stock and cash, calculated as described herein. See
"THE SPECIAL MEETING" and "THE MERGER--Consideration Payable Upon Consummation
of the Merger." The City National Board of Directors has approved the issuance
of the shares of City National Stock to be issued upon consummation of the
Merger. Approval of the shareholders of City National is not required for the
issuance of the shares of City National Stock.
 
    This Proxy Statement/Prospectus also constitutes a prospectus of City
National in respect of the shares of City National Stock to be issued in
connection with the Merger.
 
PARTIES TO THE MERGER
 
   
    CITY NATIONAL. City National, a Delaware corporation, is a bank holding
company which conducts a commercial banking business through its wholly owned
subsidiary, City National Bank, which is a national banking association. City
National Bank, which was founded in 1953, conducts business in Southern
California and operates 21 banking offices in Los Angeles County, one in Orange

reference into this Proxy Statement/Prospectus. See "INCORPORATION OF CERTAIN
DOCUMENTS BY REFERENCE."
 
    VENTURA. Ventura is a registered bank holding company conducting business
through its two subsidiary banks, Ventura Bank and Frontier Bank. As of
September 30, 1996, Ventura had total consolidated assets of $271.7 million,
total consolidated deposits of $237.9 million and total consolidated

    The principal executive offices of Ventura are located at 500 Esplanade

RIVERSIDE MERGER
 
    City National and City National Bank are also parties to the Riverside
Agreement, which contemplates the merger of Riverside with and into City
National Bank (the "Riverside Merger"). City National Bank will be the surviving
national bank in the Riverside Merger. The directors and officers of City
National Bank immediately prior to the Riverside Merger will be the directors
and officers, respectively, of the surviving national bank following the
Riverside Merger.
 
    As a result of the Riverside Merger, holders of Riverside common stock will
receive City National Stock and/or cash. The precise amount of City National
Stock to be received by Riverside shareholders depends on the Riverside Exchange
Ratio, calculated in accordance with the Riverside Agreement. However, the total
amount of City National Stock to be issued to Riverside shareholders in the
aggregate will be no less than 48%, and no greater than 60%, of the total
consideration paid in the Riverside Merger, as calculated pursuant to the
Riverside Agreement. See "PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION."
 
    The consummation of the Riverside Merger is subject to a number of
conditions, including regulatory approval and the approval of Riverside's
shareholders. Subject to the satisfaction of such conditions, the Riverside
Merger and the Merger are expected to be consummated within several weeks of
each other. While it is currently expected that the Merger is likely to be
consummated prior to the Riverside Merger, there is a possibility that the
Riverside Merger will be the first of the two transactions to close.

issued in connection with the Merger will be listed on the NYSE.
 
                              THE SPECIAL MEETING
 
RECORD DATE
 
   
    The Ventura Board of Directors has fixed the close of business on November
25, 1996 as the Record Date for the determination of shareholders entitled to
notice of, and to vote at, the Special Meeting. Accordingly, only holders of
record of shares of Ventura Stock on the Record Date will be entitled to vote at
the Special Meeting. As of the Record Date, there were 9,294,743 shares of
Ventura Stock outstanding held by approximately 916 shareholders of record.
    
 
PROXIES
 
    When a proxy card is returned, properly signed and dated, the shares
represented thereby will be voted in accordance with the instructions on the
proxy card. If a shareholder does not attend the Special Meeting and if a
shareholder does not return the signed proxy card, such holder's shares will not
be voted and this will have the effect of a vote "AGAINST" the approval of the
Merger Agreement and the Merger. Shareholders are urged to mark the box on the
proxy card to indicate how their shares are to be voted. If a shareholder
returns a signed proxy card but does not indicate how the shares represented by
the proxy card are to be voted, such shares will be voted "FOR" approval of the
Merger Agreement and the Merger. The proxy card also confers discretionary
authority on the proxyholder to vote the shares represented thereby on any other
matter that is properly presented for action at the Special Meeting. A
shareholder who has given a proxy may revoke it at any time prior to its
exercise at the Special Meeting by delivering an instrument of revocation to the
Secretary of Ventura, by duly executing and submitting a proxy card bearing a
later date, or by appearing at the Special Meeting and voting in person.
However, the mere presence at the Special Meeting of the shareholder who has
given a proxy will not revoke such proxy. In addition, brokers who hold shares
of Ventura Stock as nominees will not have discretionary authority to vote such
shares in connection with the proposal to approve the principal terms of the
Merger Agreement in the absence of instructions from the beneficial owners.
 
    Proxies will be solicited through the use of the mails. In addition, certain
directors, officers and employees of Ventura may solicit proxies (for no
additional compensation) by personal interview, telephone, telegram or similar
means of communication. Ventura has retained the services of Georgeson &
Company, Inc. to assist in soliciting proxies for stockholders and brokers,
banks and other institutions, nominees and fiduciaries for a fee estimated at
$6,000.
 
QUORUM
 
    The presence, either in person or by properly executed proxies, of the
holders of a majority of the outstanding shares of Ventura Stock is necessary to
constitute a quorum at the Special Meeting. Abstentions will be counted for
purposes of establishing a quorum and broker non-votes will not be counted for
purposes of establishing a quorum.
 
                                       45
<PAGE>
VOTE REQUIRED
 
    Ventura shareholders are entitled to one vote at the Special Meeting for
each share of Ventura Stock held of record by them on the Record Date. The
proposal concerning the approval of the principal terms of the Merger Agreement
and the Merger requires the affirmative vote of the holders of a majority of the
outstanding shares of Ventura Stock. Abstentions and broker non-votes will have
the same effect as a vote "AGAINST" the proposal, except for purposes of
entitlement to dissenters' rights. See "DISSENTERS' RIGHTS".
 
   
    As of the Record Date, directors, executive officers and affiliates of such
directors and executive officers of Ventura beneficially owned an aggregate of
1,308,730 shares of Ventura Stock (not including shares issuable upon exercise
of stock options) or approximately 14.1% of the shares outstanding as of the
Record Date. All of Ventura's directors have agreed to vote their approximately
1,291,686 shares (approximately 13.9%) in favor of the Merger Agreement and the
Merger. See "CERTAIN RELATED AGREEMENTS--Shareholders' Agreement."
    
 
   
    As of the Record Date, City National beneficially owned 12,800 shares of
Ventura Stock.
    
 
SHAREHOLDINGS OF CERTAIN BENEFICIAL OWNERS AND VENTURA'S MANAGEMENT
 
    Management of Ventura knows of no person, other than Basswood Partners,
L.P., Matthew Lindenbaum and Bennett Lindenbaum, who owns, beneficially or of
record, either individually or as a group, 5 percent or more of the outstanding
shares of Ventura Stock. The following table sets forth, as of the Record Date,
the number and percentage of shares of outstanding Ventura Stock beneficially
owned, directly or indirectly, by each of Ventura's directors and executive
officers, principal shareholders, and by the directors and officers of Ventura
as a group. In general, beneficial ownership includes shares over which the
director, principal shareholder or officer has sole or shared voting or
investment power and shares which such person has the right to acquire within 60
days of the Record Date.
 
    Unless otherwise indicated, the persons listed below have sole voting and
investment powers of the shares beneficially owned.

                                   THE MERGER
 
    The following information, insofar as it relates to matters contained in the
Merger Agreement, is qualified in its entirety by reference to the Merger
Agreement, which is incorporated herein by reference and attached hereto as
Appendix A. Ventura shareholders are urged to read the Merger Agreement
carefully.
 
BACKGROUND OF AND REASONS FOR THE MERGER
 
    During the 1990s, Ventura experienced significant declines in earnings and
increases in nonperforming assets which resulted in Ventura and its subsidiary
banks becoming subject to supervisory agreements with their respective federal
regulators. In response, in September 1993, new management brought in by the
Ventura Board of Directors developed and began to implement a plan to address
the major concerns confronting Ventura Bank and Frontier Bank and restore core
profitability, consisting of (1) improving management, (2) reducing
nonperforming and classified assets, (3) improving asset quality, (4) reducing
other expenses, (5) improving liquidity and (6) increasing capital ratios.
 
    In connection with those efforts, from 1993 through 1996, the Board of
Directors and executive officers of Ventura met at various times to consider
strategic alternatives available to Ventura and to implement a program to
improve the earnings of Ventura and enhance the value of the shareholders'
investment in Ventura. In 1994, Ventura retained Sandler O'Neill to act as
financial advisor with respect to capital augmentation, acquisition and
disposition strategies. The Ventura Board of Directors considered, among other
things, the sale of either or both subsidiary banks, as well as Ventura as a
whole. During the period from May 1994 through April 1995, Ventura was
approached by several banking institutions concerning a possible acquisition of
Ventura as a whole and Ventura Bank or Frontier Bank separately. In July 1994,
Ventura entered into a letter of intent with another financial institution for
the acquisition of Frontier Bank which was subsequently terminated. Except for
the letter of intent with respect to Frontier Bank, no understandings or
agreements were reached with any other institutions.
 
    In late 1994, the Ventura Board of Directors determined that the interests
of the Ventura shareholders would be best served by a plan focusing on
continuing to build Ventura's core business of generating and maintaining
profitable banking relationships with small and medium sized businesses,
professional firms and individuals in its market areas. In that regard, in May
1995, Ventura undertook a rights offering to shareholders and standby purchasers
in which $6.5 million in gross proceeds was raised.
 
    Subsequent to the rights offering, the Ventura Board of Directors continued
to review the strategic alternatives available to Ventura, which included the
acquisition by Ventura of other banking institutions. In February 1996, Ventura
entered into an engagement letter with Sandler O'Neill to act as its financial
advisor with respect to strategic planning and merger and acquisition
strategies. On March 13, 1996, Frank P. Pekny, City National's Executive Vice
President and Treasurer/Chief Financial Officer contacted
 
                                       47
<PAGE>
Richard S. Cupp, Ventura's Chief Executive Officer regarding the potential
acquisition of Ventura. Thereafter, Sandler O'Neill and Ventura's management and
Capital Committee identified a number of potential acquisition partners,
including City National. Each of the prospective institutions was asked to sign
a confidentiality agreement. The institutions contacted were all
California-based financial institutions.
 
    On April 30, 1996, the Capital Committee met to discuss the contacts with
the potential acquisition partners, City National's indication of interest in
Ventura and the alternatives available to Ventura. The Committee authorized
Sandler O'Neill to proceed with discussions with City National. During May and
June 1996, representatives of Sandler O'Neill met with representatives of City
National to discuss a possible combination of Ventura and City National.
Pursuant to the confidentiality agreement, during the period between June 1996
and August 1996, Ventura provided City National with documentation and
information for due diligence purposes.
 
    On July 9, 1996, James Hussey, Ventura's Chairman. and Mr. Cupp, met with
Mr. Pekny and Heng W. Chen, City National Bank's Senior Vice
President-Finance/Controller, along with Thomas Killian of Sandler O'Neill to
discuss a pro forma analysis of the companies. Mr. Pekny and Mr. Chen informed
City National's senior management of the results of these meetings and on July
12, City National authorized Mr. Pekny to proceed with discussions. Between July
12, 1996 and July 25, 1996, discussions continued. At that time, it was
determined that City National would complete its due diligence review before
moving forward with further discussions. During August 1996, City National
continued its off-site due diligence review of Ventura, Ventura Bank and
Frontier Bank. On August 24, 1996, Mr. Cupp and Mr. Pekny met to discuss pricing
issues. On August 28, 1996, Messrs. Hussey, Cupp, Pekny, Chen and Killian met to
further discuss the proposal, and reached preliminary agreement on a number of
issues. On August 30 and 31, 1996, City National conducted on-site diligence
reviews and discussions with management of Ventura Bank and Frontier Bank.
 
    On September 4 and 5, 1996, representatives of Sandler O'Neill conducted a
due diligence review of City National, including discussions with management.
From September 8 to 15, 1996, representatives of Ventura and City National met
and had numerous telephone conversations to negotiate the final terms of the
Merger Agreement, the Option Agreement and the Shareholders' Agreement. See
"CERTAIN RELATED AGREEMENTS--Shareholders' Agreement" and "CERTAIN RELATED
AGREEMENTS--Option Agreement" below.
 
    On September 15, 1996, the Board of Directors of Ventura met to consider the
proposal submitted by City National. Following presentations from management of
Ventura and Ventura's financial and legal advisors, the Board of Directors of
Ventura approved the terms of City National's proposal and the Merger pursuant
to the Merger Agreement. The Merger Agreement, Option Agreement and
Shareholders' Agreement were executed on September 15, 1996.
 
    In evaluating the proposed Merger with City National, the Board of Directors
of Ventura considered a variety of factors, reviewed information relating to
City National and Ventura and received reports from and presentations by its
officers, financial advisors and legal counsel. Among the factors considered by
the Board of Directors were the fact that the value of the consideration to be
paid in the Merger represents a premium over the current market price of Ventura
Stock; the value and form of the consideration to be paid in the Merger compared
with prices paid in acquisitions of the other banks and bank holding companies;
the book value and earnings per share of Ventura; the results of operations and
prospects of Ventura and City National; alternatives to an acquisition of
Ventura, including the advisability of continuing to operate Ventura as an
independent entity; the opinion of Sandler O'Neill, confirmed in a letter to the
Board of Directors, that the consideration to be received in the Merger is fair
from a financial point of view to shareholders of Ventura (see "Opinion of
Financial Advisor to Ventura," below); the tax consequences of the transaction
to shareholders of Ventura; and the value of City National Stock as an
investment, including the fact that it pays a dividend and offers the Ventura
shareholders the opportunity to participate in the future performance of a
larger financial institution than Ventura. The Ventura Board
 
                                       48
<PAGE>
concluded, in light of these factors and other factors it considered
appropriate, that the Merger is in the best interests of Ventura and its
shareholders.

THE VENTURA BOARD OF DIRECTORS HAS UNANIMOUSLY CONCLUDED THAT THE MERGER IS IN

VENTURA HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT, THE MERGER AND THE

OPINION OF FINANCIAL ADVISOR TO VENTURA
 
    The following information was provided by Sandler O'Neill.
 
    Pursuant to a letter agreement dated as of February 9, 1996, (the "Sandler
O'Neill Agreement"), Ventura retained Sandler O'Neill as an independent
financial advisor in connection with strategic planning and merger and
acquisition transactions. Sandler O'Neill is a nationally recognized investment
banking firm whose principal business specialty is banks and savings
institutions and is regularly engaged in the valuation of such businesses and
their securities in connection with mergers and acquisitions and other corporate
transactions.
 
   
    Pursuant to the terms of the Sandler O'Neill Agreement, Sandler O'Neill
acted as financial advisor to Ventura in connection with the Merger. In
connection therewith, at the September 15, 1996 meeting at which Ventura's Board
approved and adopted the Merger Agreement, Sandler O'Neill delivered a written
opinion to Ventura's Board that, as of such date, the consideration to be
received by the holders of shares of Ventura Common Stock pursuant to the Merger
Agreement was fair, from a financial point of view, to such shareholders. THE
SEPTEMBER 15, 1996 WRITTEN OPINION WAS CONFIRMED ON DECEMBER 4, 1996 (AS
CONFIRMED, THE "FAIRNESS OPINION"). THE FULL TEXT OF THE FAIRNESS OPINION, WHICH
SETS FORTH THE PROCEDURES FOLLOWED, ASSUMPTIONS MADE, MATTERS CONSIDERED AND
QUALIFICATIONS AND LIMITATIONS ON THE REVIEW UNDERTAKEN, IS ATTACHED AS APPENDIX
E TO THIS PROXY STATEMENT AND IS INCORPORATED HEREIN BY REFERENCE. THE
DESCRIPTION OF SUCH OPINION SET FORTH HEREIN IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO APPENDIX E. HOLDERS OF VENTURA STOCK ARE URGED TO READ THE FAIRNESS
OPINION IN ITS ENTIRETY IN CONNECTION WITH THEIR CONSIDERATION OF THE PROPOSED
MERGER. SANDLER O'NEILL'S FAIRNESS OPINION SHOULD NOT BE CONSTRUED BY THE
HOLDERS OF SHARES OF VENTURA STOCK AS A RECOMMENDATION AS TO HOW THEY SHOULD
VOTE AT THE SPECIAL MEETING.
    
 
    In connection with rendering the Fairness Opinion, Sandler O'Neill performed
a variety of financial analyses. The following is a summary of such analyses,
but does not purport to be a complete description of Sandler O'Neill's analysis.
The preparation of a fairness opinion is a complex process involving subjective
judgements and is not necessarily susceptible to a partial analysis or summary
description. Sandler O'Neill believes that its analyses must be considered as a
whole and that selecting portions of such analyses and the factors considered
therein, without considering all factors and analyses, could create an
incomplete view of the analyses and processes underlying the Fairness Opinion.
In performing its analyses, Sandler O'Neill made numerous assumptions with
respect to industry performance, business and economic conditions and various
other matters, many of which cannot be predicted and are beyond the control of
Ventura, City National and Sandler O'Neill. Any estimates contained in Sandler
O'Neill's analyses are not necessarily indicative of future results or values,
which may be significantly more or less favorable than such estimates. Estimates
on the values of companies do not purport to be appraisals or necessarily
reflect the prices at which companies or their securities may actually be sold.
Because such estimates are inherently subject to uncertainty, none of Ventura,
City National nor Sandler O'Neill assumes responsibility for their accuracy.

    STOCK TRADING HISTORY. Sandler O'Neill examined the history of the trading
prices and the volume of Ventura Stock and City National Stock, and the
relationship between the movements in the prices of the Ventura Stock and City
National Stock, respectively, to movements in certain stock indices, including
the Standard & Poor's 500 Index, the Nasdaq Banking Index and a composite group
of publicly traded commercial banks in geographic proximity and of similar asset
size.
    
 
    ANALYSIS OF SELECTED PUBLICLY TRADED COMPANIES. In preparing its
presentation, Sandler O'Neill used publicly available information to compare
selected financial and market trading information, including book value,

    ANALYSIS OF SELECTED MERGER TRANSACTIONS. Sandler O'Neill reviewed 7
transactions announced from January 1, 1996 to September 6, 1996 involving
California commercial banks as targets with transaction values over $15 million
and less than $100 million ("1996 California Transactions"), 14 transactions
announced from January 1, 1995 to September 6, 1996 involving California
commercial banks as targets with transaction values over $15 million, and less
than $100 million ("1995-96 California Transactions"), and 19 transactions
announced from January 1, 1996 to September 6, 1996 involving commercial banks
nationwide as targets with equity/assets of 10% or greater ("Highly Capitalized
Transactions"). Sandler O'Neill reviewed the ratios of price to earnings, price
to book value, price to tangible book value, price to deposits, price to assets,
and deposit premium paid in each such transaction and computed high, low, mean,
and median ratios and premiums for the respective groups of transactions. Based
upon the median multiples for 1996 California Transactions, Sandler O'Neill
derived an imputed range of values per share of Ventura Stock of $3.29 to $4.93.
Based upon the median multiples for 1995-96 California Transactions, Sandler
O'Neill derived an imputed range of values per share of Ventura Stock of $2.63
to $4.78. Based upon the median multiples for Highly Capitalized Transactions,
Sandler O'Neill derived an imputed range of values per share of Ventura Stock of
$2.45 to $6.74.
 
    DISCOUNTED DIVIDEND STREAM AND TERMINAL VALUE ANALYSIS. Sandler O'Neill also
performed an analysis which estimated the future stream of after-tax dividend
flows of Ventura through 2000 under various circumstances, assuming Ventura
performed in accordance with the earnings forecasts of its management and
certain variations thereof (including variation with respect to the growth rate
of assets, net interest spread, non-interest income, non-interest expense and
dividend payout ratio). To approximate the terminal value of Ventura Stock at
the end of the five-year period, Sandler O'Neill applied price to earnings
multiples ranging from 8x to 17x and applied multiples of book value ranging
from 120.0% to 210.0%. The dividend income streams and terminal values were then
discounted to present values using different discount rates (ranging from 9.0%
to 14.0%) chosen to reflect different assumptions regarding required rates of
return of holders of prospective buyers of Ventura Stock. This analysis,
assuming the current dividend payout ratio, indicated an imputed range of values
per share of Ventura Stock between $3.04 and $7.89 when applying the price to
earnings multiples, and an imputed range of values per share of Ventura Stock
between $3.51 and $7.51 when applying multiples of book value. In connection
with its analysis, Sandler O'Neill extensively used sensitivity analyses to
illustrate the effects changes in the underlying assumptions would have on the
resulting present value, and discussed these changes with Ventura's Board of
Directors.
 
                                       52
<PAGE>
    In addition, Sandler O'Neill performed an analysis which estimated the
future stream of after-tax dividend flows of City National on a pro-forma basis,
assuming consummation of the Merger (the "Combined Company") through 2001 under
various circumstances, assuming (i) the operations of the Combined Company
attributable to Ventura performed in accordance with the earnings forecasts of
Ventura's management and certain variations thereof, as described in the
previous paragraph; (ii) the operations of the Combined Company attributable to
City National performed in accordance with certain publicly available earnings
forecasts prepared by financial analysts and certain variations thereof
(including variation with respect to the growth rate of assets, net interest
spread, non-interest income, non-interest expense and dividend payout ratio);
and (iii) the Combined Company realized cost savings equal to 40% of Ventura's
projected non-interest expenses. To approximate the terminal value of the
Combined Company's common stock at the end of the five-year period, Sandler
O'Neill applied price to earnings multiples ranging from 13.5x to 16.2x, and
applied multiples of book value ranging from 210% to 220.0%. The dividend income
streams and terminal values were then discounted to present value using a
discount rate of 13.5%. This analysis, assuming the current dividend payout
ratio, indicated an imputed range of values of the shares of City National Stock
to be received in the Merger of approximately $15.37 to $21.16 when applying the
price to earnings multiples, and an imputed range of values of the shares of
City National Stock to be issued in the Merger of approximately $16.00 to $21.30
when applying multiples of book value. In connection with its analysis, Sandler
O'Neill extensively used sensitivity analyses to illustrate the effects changes
in the underlying assumptions would have on the resulting present value, and
discussed these changes with Ventura's Board of Directors.
 
   
    In connection with rendering the Fairness Opinion, Sandler O'Neill confirmed
the appropriateness of its reliance on the analysis used to render its September
15, 1996 opinion by performing procedures to update certain of such analyses and
by reviewing the assumptions on which such analyses were based and the factors
considered in connection therewith. Sandler O'Neill also reviewed, among other
things: (i) the Merger Agreement and exhibits thereto; (ii) the Stock Option
Agreement dated as of September 15, 1996 by and between City National and
Ventura; (iii) a draft of this Proxy Statement/Prospectus; (iv) the audited
consolidated financial statements and management's discussion and analysis of
the condition and results of operations of each of City National, Ventura and
Riverside for the three years ended December 31, 1995; (v) the unaudited
consolidated financial statements and management's discussion and analysis of
the financial condition and results of operations of each of City National,
Ventura and Riverside for the interim periods ended March 31, 1996, June 30,
1996 and September 30, 1996; (vi) certain financial analyses and forecasts of
Ventura prepared by and/or reviewed with management of Ventura and the views of
senior management of Ventura regarding Ventura's past and current business
operations, results thereof, financial condition and future prospects; (vii)
certain financial analyses and forecasts of City National prepared by and/or
reviewed with management of City National and the views of senior management of
City National regarding City National's past and current business operations,
results thereof, financial condition and future prospects; (viii) the pro forma
impact of the Merger and City National's acquisition of Riverside on City
National; (ix) the historical reported price and trading activity for City
National Stock and Ventura Stock, including a comparison of certain financial
and stock market information for City National and Ventura with similar
information for certain other companies the securities of which are publicly
traded; (x) the financial terms of recent business combinations in the banking
industry; (xi) the current market environment generally and the banking
environment in particular; and (xii) such other information, financial studies,
analyses and investigations and financial, economic and market criteria as
Sandler O'Neill considered relevant, including the intended tax deferred nature
of the Merger, the potential benefits of the cash or stock election to the
holders of the shares and Ventura's recent history of inconsistent profitability
and uncertain level of future profitability.
    
 
   
    In performing its review, Sandler O'Neill assumed and relied upon, without
independent verification, the accuracy and completeness of all the financial
information, analyses and other information reviewed by and discussed with
Sandler O'Neill (relying, where relevant, on the analyses and estimates of City
National and Ventura), and Sandler O'Neill did not make an independent
evaluation or appraisal of specific assets,
    
 
                                       53
<PAGE>
   
the collateral securing assets or the liabilities of City National, Ventura or
Riverside or any of their subsidiaries, or the collectibility of any such
assets. With respect to the financial projections reviewed with each company's
management, Sandler O'Neill assumed that they have been reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
respective managements of the respective future financial performances of City
National and Ventura and that such performances will be achieved. Sandler
O'Neill also assumed the following: (i) that there has been no material change
in City National's or Ventura's assets, financial condition, results of
operations, business or prospects since the date of the last financial
statements noted above and (ii) that City National will remain as a going
concern for all periods relevant to Sandler O'Neill's analyses and that the
conditions precedent in the Merger Agreement are not waived.
    
 
    Under the Sandler O'Neill Agreement, Ventura will pay Sandler O'Neill a
transaction fee in connection with the Merger, a substantial portion of which is
contingent upon the consummation of the Merger. Under the terms of the Sandler
O'Neill Agreement, Ventura will pay Sandler O'Neill a transaction fee equal to
1.0% of the aggregate purchase price paid in the transaction, or approximately
$470,000, of which 25% was paid on the date of execution of the Merger Agreement
and 75% is payable on the day of closing of the transaction. Ventura has also
paid Sandler O'Neill a fee of $50,000 for rendering the Fairness Opinion.
Ventura has also agreed to reimburse Sandler O'Neill for its reasonable
out-of-pocket expenses incurred in connection with its engagement and to
indemnify Sandler O'Neill and its affiliates and their respective partners,
directors, officers, employees, agents, and controlling persons against certain
expenses and liabilities, including liabilities under securities laws.
Principals of Sandler O'Neill owned approximately 525,000 shares of Ventura
Stock as of the Record Date.
 
EFFECT OF THE MERGER
 
    THE MERGER.  At the Effective Time, Ventura will merge with and into City
National. City National will be the surviving corporation. At the Effective
Time, the City National Certificate and the City National By-laws as in effect
immediately prior thereto will be the Certificate of Incorporation and By-laws
of the surviving corporation. In addition, the directors and officers of City
National immediately prior to the Effective Time will continue as the directors
and officers of the surviving corporation.
 
    THE BANK MERGERS.  City National intends to cause Ventura Bank and Frontier
Bank to merge with and into City National Bank immediately following the Merger.
 
CONSIDERATION PAYABLE UPON CONSUMMATION OF THE MERGER
 
    CONVERSION OF VENTURA STOCK.  In the aggregate, 55% of the shares of Ventura
Stock issued and outstanding immediately prior to the Effective Time (other than
Dissenting Shares and Cancelled Shares) will be converted into the right to
receive City National Stock and 45% of such shares of Ventura Stock will be
converted into the right to receive cash. Holders of Ventura Stock will have the
opportunity to indicate their preference for receiving a different proportion of
cash and City National Stock in the Merger, and may indicate a preference for
receiving all cash or all City National Stock. Such Elections will be honored to
the extent possible; provided, that in the aggregate 55% of Ventura shares will
receive City National Stock and 45% of Ventura shares will receive cash.
 
    Each such share of Ventura Stock will, by virtue of the Merger, be converted
into the right to receive either:
 
        (1) a fraction of a share of City National Stock equal to the quotient
    (such quotient, the "Exchange Ratio") of (A) $5.03, divided by (B) the
    average of the daily closing prices of a share of City National Stock on the
    NYSE as reported in the WALL STREET JOURNAL for the twenty consecutive
    trading days ending on the third trading day immediately prior to the
    Effective Time (such average, the "Final City National Stock Price");
    provided, however, that if the Final City National Stock Price is more than
    $19.10, the Exchange Ratio will be based upon a Final City National Stock
    Price of
 
                                       54
<PAGE>
    $19.10 and, accordingly, will be fixed at 0.2634, and if the Final City
    National Stock Price is less than $15.65, the Exchange Ratio will be based
    upon a Final City National Stock Price of $15.65 and, accordingly, will be
    fixed at 0.3214;
 
        (2) cash in the amount of $5.03; or
 
        (3) a combination of City National Stock (at the rate of the Exchange
    Ratio for a whole share of Ventura Stock) and cash (at the rate of $5.03 for
    a whole share of Ventura Stock).
 
    At the Effective Time, Cancelled Shares, shall be cancelled, retired and
shall cease to exist, and no exchange or payment shall be made with respect to
such Cancelled Shares.
 
   
    ELECTION AND PRORATION PROCEDURE.  A form of transmittal letter ("Letter of
Transmittal") is being mailed with this Proxy Statement/Prospectus to each
holder of record of Ventura Stock as of five business days prior to the date of
this Proxy Statement/Prospectus. Each Letter of Transmittal will permit the
holder to elect (an "Election") to receive either (1) City National Stock with
respect to all of such holder's Ventura Stock (a "Stock Election"), or (2) cash
with respect to all of such holder's Ventura Stock (a "Cash Election"), or (3) a
combination of shares of City National Stock and cash in the proportions
specified on the Letter of Transmittal (a "Combination Election").
    
 
    Any Ventura Stock (other than Dissenting Shares) with respect to which IBJ
Schroder Bank & Trust Company (the "Exchange Agent") does not receive an
effective, properly completed Letter of Transmittal prior to the Election
Deadline (as hereinafter defined) will be deemed to be "Undesignated Shares."
 
   
    An Election will be properly made and effective only if the Exchange Agent
actually receives a properly completed Letter of Transmittal by 5:00 P.M. on or
before January 15, 1997, unless extended to a later date by the mutual agreement
of the parties (the "Election Deadline"). A Letter of Transmittal will be deemed
properly completed only if an Election is indicated for each share of Ventura
Stock covered by such Letter of Transmittal and if accompanied by one or more
certificates (or customary affidavits and indemnity regarding the loss or
destruction of such certificates or the guaranteed delivery of such
certificates, each as set forth in the Letter of Transmittal) representing all
shares of Ventura Stock covered by such Letter of Transmittal, together with
duly executed transmittal materials included in or required by the Letter of
Transmittal.
    
 
    An Election may be revoked or changed at any time prior to the Election
Deadline. In the event an Election is revoked prior to the Election Deadline,
the related shares of Ventura Stock will automatically become Undesignated
Shares unless and until a new Election is properly made with respect to such
shares on or before the Election Deadline.
 
    In the event that the aggregate number of shares of Ventura Stock as to
which Stock Elections and Combination Elections for Ventura Stock have been
effectively made exceeds the Stock Amount, then (1) all Undesignated Shares and
Dissenting Shares will be deemed to have made Cash Elections and (2) each holder
of Ventura Stock who made an effective Stock Election or Combination Election
for City National Stock will be entitled to a prorated number of shares of City
National Stock and a prorated amount of cash such that approximately the Stock
Amount is converted into shares of City National Stock.
 
    Correspondingly, in the event that the aggregate number of shares of Ventura
Stock as to which Stock Elections and Combination Elections for Ventura Stock
have effectively been made is less than the Stock Amount, then the Exchange
Agent will select by lot such number of holders of Undesignated Shares to
receive City National Stock as will be necessary so that the number of shares
for which a Stock Election and Combination Election for City National Stock has
been made or is deemed to have been made with respect to such Undesignated
Shares will be approximately equal to the Stock Amount. In the event that all
Undesignated Shares plus all shares as to which Stock Elections and Combination
Elections for Ventura Stock have been made are less than the Stock Amount, then
each holder of Ventura Stock who made an effective Cash Election or Combination
Election for cash will be entitled to a prorated amount of cash and
 
                                       55
<PAGE>
a prorated number of shares of City National Stock such that approximately the
Stock Amount is converted into shares of City National Stock.
 
   
    BECAUSE OF THE PRORATION PROCEDURE DESCRIBED ABOVE, HOLDERS OF VENTURA STOCK
ARE UNLIKELY TO RECEIVE THE PRECISE PROPORTION OF CITY NATIONAL STOCK AND/OR
CASH INDICATED BY SUCH HOLDER'S ELECTION.
    
 
    For a more complete discussion of the foregoing proration procedure see
Section 2.3 of the Merger Agreement.
 
    For a discussion of the rights of dissenting shareholders of Ventura, see
"DISSENTERS' RIGHTS."
 
    NO FRACTIONAL SHARES. Notwithstanding the foregoing, each holder of shares
of Ventura Stock exchanged pursuant to the Merger who would otherwise have been
entitled to receive a fraction of a share of City National Stock (after taking
into account all certificates delivered by such holder) shall receive, in lieu
thereof, cash (without interest) in an amount equal to such fractional part of a
share of City National Stock multiplied by the Final City National Stock Price.
No holder will be entitled to dividends, voting rights or any other rights as a
stockholder in respect of any fractional share of City National Stock.
 
EFFECTIVE TIME
 
    The Effective Time of the Merger will be the date the certificate of merger
is filed in accordance with Sections 251 and 252 of the Delaware General
Corporation Law (the "Delaware Code"). On or about the Effective Time, (1) an
executed counterpart of such certificate of merger or (2) a copy of the Merger
Agreement, with an officer's certificate conforming to Section 1103 of the
California Code of each of City National and Ventura, and in either case, a tax
clearance certificate from the California Franchise Tax Board with respect to
Ventura, will be filed with the Secretary of State of the State of California.
 
   
    If the Merger is approved by the shareholders of Ventura, subject to the
satisfaction or waiver of certain conditions described herein, the Effective
Time currently is expected to occur during the first quarter of 1997.
    
 
SURRENDER OF VENTURA STOCK CERTIFICATES
 
    As soon as practicable following the Effective Time, and after the proration
procedures described above are completed, each holder of Ventura Stock who
submits (or submitted) a properly completed Letter of Transmittal will be issued
a certificate or certificates representing the number of shares of City National
Stock to which such holder is entitled, if any (and, if applicable, a check for
the amount to be paid in lieu of fractional shares of City National Stock),
and/or an amount of cash to which such holder is entitled, if any. Holders of
Ventura Stock who did not submit a Letter of Transmittal prior to the Election
Deadline must nevertheless submit a properly completed Letter of Transmittal
(other than the section pertaining to the Election) and the certificate or
certificates representing Ventura Stock to the Exchange Agent in order to
receive the Merger consideration payable in respect of such shares.
 
    After the Effective Time, there will be no transfers on Ventura's stock
transfer books of shares of Ventura Stock issued and outstanding immediately
prior to the Effective Time. If certificates representing shares of Ventura
Stock are presented for transfer after the Effective Time, together with
documents sufficient to evidence and effect such transfer, they will be
cancelled and exchanged for the shares of City National Stock and/or cash, if
any, deliverable in respect thereof.
 
    No dividend or other distribution declared or made with respect to City
National Stock with a record date after the Effective Time will be paid to the
holder of any unsurrendered certificate of Ventura Stock until the holder duly
surrenders such certificate. Following the surrender of any such certificate,
there will be paid to the holder, without interest, (1) the amount of any cash
payable with respect to a fractional share of City National Stock to which such
holder is entitled and the amount of dividends or other distributions with a
record date after the Effective Time theretofore paid with respect to such whole
shares
 
                                       56
<PAGE>
of City National Stock and (2) at the appropriate payment date, the amount of
dividends or other distributions with (A) a record date after the Effective Time
but prior to surrender and (B) a payment date subsequent to surrender payable
with respect to such shares of City National Stock.
 
    None of City National, Ventura, the Exchange Agent or any other person will
be liable to any former holder of Ventura Stock for any shares of City National
Stock (or dividends or distributions with respect thereto) or cash delivered to
a public official pursuant to applicable unclaimed property, abandoned property,
escheat or similar laws.
 
    If a certificate for Ventura Stock has been lost, stolen or destroyed, the
Exchange Agent will issue the consideration properly payable in accordance with
the Merger Agreement upon receipt of appropriate evidence as to such loss, theft
or destruction, appropriate evidence as to the ownership of such certificate by
the claimant, and appropriate and customary indemnification.
 
    Any shares as to which dissenters' rights have been perfected will be
purchased in accordance with the procedures described under "DISSENTERS' RIGHTS"
and in Appendix B to this Proxy Statement/ Prospectus.

REGULATORY APPROVALS
 
   
    THE MERGER.  Receipt of the Regulatory Approvals is a condition to each
party's obligations to effect the Merger. See "Conditions to Consummation of the
Merger" above, and "Amendment and Termination" below. On December 3, 1996, City
National received the approval of the Board of Governors of the Federal Reserve
System required in order to consummate the Merger.
    
 
   
    THE BANK MERGERS.  The Bank Mergers are subject to the prior approvals of
the OCC. The Bank Merger Act prohibits the OCC from approving a Bank Merger (1)
if it would result in a monopoly or be in furtherance of any combination or
conspiracy to monopolize or to attempt to monopolize the business of banking in
any part of the United States, or (2) if its effect in any section of the
country may be substantially to lessen competition or tend to create a monopoly,
or if it would in any other manner be a restraint of trade, unless the OCC finds
that the anticompetitive effects of the Bank Merger are clearly outweighed by
the public interest and the probable effect of the transaction in meeting the
convenience and needs of the communities to be served. Under the Bank Merger Act
and applicable regulations, a Bank Merger may not be consummated until the 15th
day following the date of receipt of OCC approval, during which time the United
States Department of Justice may challenge a Bank Merger on antitrust grounds.
In addition, the Bank Merger Act requires that the OCC take into consideration,
among other factors, the financial and managerial resources and future prospects
of the institutions and the convenience and needs of the communities to be
served. The OCC has the authority to deny an application if it concludes that
the combined organization would have an inadequate capital position or if the
requirements of the Community Reinvestment Act are not satisfied.
    
 
    An application for the requisite approvals of the Bank Mergers by the OCC
has been submitted. No assurances can be given, however, that such approvals
will be received or that the Bank Mergers will be consummated.
 
CONDUCT OF BUSINESS PENDING THE MERGER
 
    VENTURA.  The Merger Agreement contains certain restrictions on the conduct
of Ventura's business pending consummation of the Merger.
 
    In particular, prior to the Effective Time, the Merger Agreement requires
each of Ventura, Ventura Bank and Frontier Bank to (1) conduct business in the
usual, regular and ordinary course, consistent with past practice; (2) use
commercially reasonable efforts to maintain and preserve intact its business
organization, employees and advantageous business relationships, and to continue
to develop such customer relationships and to retain the services of its key
employees; (3) maintain properties; (4) use commercially reasonable efforts to
maintain insurance coverage; (5) perform, in all material respects, its
obligations under material contracts, leases and documents relating to or
affecting its assets, properties and business except as it may in good faith
reasonably dispute; (6) charge off all loans, receivables and other assets, or
portions thereof, deemed uncollectible in accordance with generally accepted
accounting principles ("GAAP"), regulatory accounting principles ("RAP"),
applicable law or regulations, or classified as "loss" or as directed by its
regulators; (7) substantially comply with all federal and state laws and rules,
regulations or orders; and (8) take no action which would reasonably be expected
to adversely affect or delay the parties' ability to obtain any Regulatory
Approvals, or other approvals required for the Merger or to perform its
covenants or agreements under the Merger Agreement on a timely basis.
 
    Without the prior written consent of City National, Ventura, Ventura Bank
and Frontier Bank may not take certain specified actions, including, but not
limited to, the following: (1) borrow money or guaranty the obligations of any
other person (except for ordinary course banking transactions or certain
short-term borrowings); (2) enter into transactions or make adjustments
involving its stock (other than upon the exercise of options outstanding under
the Option Plan or the payment to the option holder of the spread between $5.03
and the exercise price of any such option); or declare or pay dividends; (3)
transfer
 
                                       59
<PAGE>
or encumber assets with a book value of $250,000 or more; (4) sell OREO or
similarly held properties for less than 80% of book value; (5) make material
investments or acquisitions; (6) enter into, renew, amend or terminate any
material contract (other than deposit and loan agreements or in the ordinary
course of business with respect to certain specified contracts); (7) alter its
method of establishing interest rates for deposits; (8) increase compensation or
benefits of directors, employees, former employees or retirees; agree to or
amend any pension, retirement, retention, "golden parachute" or other severance
(other than in accordance with the Merger Agreement), deferred compensation,
profit sharing or welfare benefit plan or agreement or employment agreement,
other than annual salary and bonus increases made in the ordinary course of
business not exceeding 2% in the aggregate or 6% for any employee; or
voluntarily accelerate the vesting of any employee benefits, except for the
acceleration of the vesting of options granted pursuant to the Option Plan; (9)
settle claims involving material monetary damages (except to the extent fully
reserved against on its books and records) or under terms containing material
obligations; (10) sell securities and certain SBA loans or purchase securities
other than U. S. treasury or agency securities maturing within three years; (11)
amend its charter documents; (12) change or introduce new services, products, or
campaigns or open or close any branch or facility; (13) renew, extend or
materially alter any loan or forbearance agreement for a period of greater than
six months, or make any loan or forbearance agreement, which would result in
total obligations outstanding exceeding specified levels; and (14) reallocate or
reduce any material accrual or reserve.
 
    CITY NATIONAL.  City National has agreed not to (1) take any action which
would reasonably be expected to delay or adversely affect the ability of City
National, Ventura, Ventura Bank or Frontier Bank to obtain any necessary
approvals, consents or waivers of any governmental authority required for the
transactions contemplated by the Merger Agreement or to perform its covenants or
agreements on a timely basis under the Merger Agreement; (2) amend the City
National Certificate in any respect that materially and adversely affects the
rights and privileges attendant to the City National Stock; or (3) agree to, or
make any commitment to, do any of the foregoing.
 
NO SOLICITATION
 
    Ventura has agreed in the Merger Agreement that it will not authorize or
permit any of its officers, directors, employees or agents to directly or
indirectly solicit, initiate or encourage any inquiries relating to, or the
making of any proposal which constitutes a "Takeover Proposal" (as defined
below), or recommend or endorse any Takeover Proposal, or participate in any
discussions or negotiations, or provide third parties with any nonpublic
information, relating to any such inquiry or proposal or otherwise facilitate
any effort or attempt to make or implement a Takeover Proposal, except if
Ventura's Board of Directors, after having consulted with and considered the
advice of counsel, has reasonably determined in good faith that the failure to
do so would cause the members of its Board of Directors to breach their
fiduciary duties under applicable laws. Ventura has agreed to cease and cause to
be terminated any activities, discussions or negotiations conducted prior to the
date of the Merger Agreement with any parties other than City National with
respect to any of the foregoing. Ventura has also agreed to immediately advise
City National following the receipt by it of any Takeover Proposal and the
details thereof, and advise City National of any developments with respect to
such Takeover Proposal immediately upon the occurrence thereof.
 
    "Takeover Proposal" means, with respect to any person, any tender or
exchange offer, proposal for a merger, consolidation or other business
combination involving Ventura or any of its subsidiaries or any proposal or
offer to acquire in any manner a substantial equity interest in, or a
substantial portion of the assets of, Ventura or any of its subsidiaries other
than the transactions contemplated or permitted by the Merger Agreement.
 
                                       60
<PAGE>
AMENDMENT AND TERMINATION
 
    AMENDMENT.  Subject to compliance with applicable law, prior to the
Effective Time, the Merger Agreement may be amended or modified by the parties
thereto, except that, after the vote by the shareholders of Ventura, any
amendment which reduces the amount or changes the form of the consideration to
be delivered to the Ventura shareholders in the Merger will not be valid without
approval of the shareholders of Ventura.
 
    TERMINATION.  The Merger Agreement may be terminated at any time prior to
the Effective Time, either before or after its approval by the shareholders of
Ventura, (1) by mutual agreement; (2) by either party in the event of an uncured
material breach by the other party of any representation, warranty, covenant or
agreement contained in the Merger Agreement; (3) by either party if any
Regulatory Approval has been denied or any governmental authority or court shall
have issued a final, non-appealable order enjoining or otherwise prohibiting
consummation of the Merger; (4) by either party in the event that the Merger is
not consummated by May 31, 1997; (5) by either party if the required vote of the
shareholders of Ventura approving the Merger Agreement is not obtained at a duly
held meeting of shareholders; (6) by City National if the Board of Directors of
Ventura shall have withdrawn, modified or changed in a manner adverse to City
National its approval or recommendation of the Merger Agreement and the Merger;
(7) by Ventura, if the Final City National Stock Price is less than $13.90; (8)
by City National, if (A) Ventura shall have provided information to or
participated in discussions with a third party relating to a Takeover Proposal,
or facilitated or recommended a Takeover Proposal and shall have continued
discussions with any third party concerning such Takeover Proposal for more than
10 business days after the date of receipt of such Takeover Proposal; or (B) a
Takeover Proposal that is publicly disclosed shall have been commenced, publicly
proposed or communicated to Ventura which contains a proposal as to price
(without regard to the specificity of such price proposal) and Ventura shall not
have rejected such proposal within 10 business days of its receipt or the date
its existence first becomes publicly disclosed, if earlier; or (9) by Ventura if
a Takeover Proposal exists and the Board of Directors of Ventura, after having
consulted with and considered the advice of outside legal counsel, reasonably
determine in good faith that such action is necessary in the exercise of its
fiduciary duties under applicable law.
 
   
    As discussed above, if the Final City National Stock Price is less than
$13.90, the Ventura Board of Directors may, in its discretion, terminate the
Merger Agreement. On December 3, 1996, the closing price for the City National
Stock was $20.625. In making any such determination, the Ventura Board of
Directors anticipates that it would review current information relating to City
National and Ventura, receive presentations from its officers, financial advisor
and legal counsel and consider a variety of factors including those which it
considered in making its initial decision to enter into the Merger Agreement.
See "THE MERGER--Background of and Reasons for the Merger." If the Merger
Agreement is approved by a majority of the outstanding shares of Ventura Stock,
the Board of Directors of Ventura will have the power and authority, without the
necessity of a further vote of the Ventura shareholders, to determine whether or
not to proceed with the Merger as provided in the Merger Agreement. As such, the
Board of Directors may determine not to exercise a right to terminate the Merger
Agreement if the Final City Stock Price is less than $13.90.
    
 
BANK MERGERS
 
    Following the Bank Mergers, the articles of association and by-laws of City
National Bank as in effect immediately prior thereto will be the articles of
association and by-laws of the surviving corporation. In addition, the directors
and officers of City National Bank immediately prior to the Bank Mergers will be
the directors and officers, respectively, of the surviving corporation. The Bank
Mergers are subject to certain regulatory approvals. See "Regulatory Approvals,"
above.

INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
   
    As of the Record Date, the directors and executive officers of Ventura
(including the executive officers of Ventura Bank and Frontier Bank)
beneficially owned 1,308,730 shares of Ventura Stock (not including shares such
persons may acquire through the exercise of vested stock options) which will be
converted into the right to receive cash or City National Stock or both at the
Effective Time in the same manner as will the shares of Ventura Stock held by
all other Ventura shareholders. In addition, directors and executive officers of
Ventura (including the executive officers of Ventura Bank and Frontier Bank)
held as of such date options to purchase 196,116 shares of Ventura Stock, which
will be exercised or canceled in exchange for certain cash payments in
connection with the Merger. Immediately after the Effective Time, former
directors and executive officers of Ventura as a group will own less than 1% of
the outstanding shares of City National Stock.
    
 
    Pursuant to the terms of an employment agreement and a benefit and salary
continuation agreement entered into with Richard Cupp (President and Chief
Executive Officer of Ventura and Ventura Bank) in July 1993 and the terms of
employment agreements entered into with Kathleen Kellogg (President and Chief
Executive Officer of Frontier Bank) in December 1994, Carl Raggio (Executive
Vice President/Chief Credit Officer of Ventura Bank) in October, 1994 and Simone
Lagomarsino (Senior Vice President/Chief Financial Officer of Ventura, Ventura
Bank and Frontier Bank) in March 1995 (collectively, the "Employment
Agreements"), upon termination of employment upon a change of control of Ventura
(as defined in such agreements), such as the Merger pursuant to the Merger
Agreement, the person whose employment has been so terminated shall be entitled
to receive a lump sum payment in an amount equal to, for Mr. Cupp, severance
payment in an amount equal to 9 months' salary and salary and benefit
continuation payment equal to three years' salary, subject to golden parachute
limitations, or $726,913 in the aggregate; for Ms. Kellogg, severance payment in
an amount equal to 9 months' salary and salary and benefit continuation payment
equal to one year's salary, or $259,525 in the aggregate; for Mr. Raggio,
severance payment in an amount equal to 6 months' salary and bonus and benefit
and salary continuation payment equal to 6 months' salary, or approximately
$163,786 in the aggregate; and for Ms. Lagomarsino, severance payment in an
amount equal to 6 months' salary and benefit and salary continuation payment
equal to 6 months' salary, or $128,150 in the aggregate.
 
    City National has requested each of Richard Cupp, Kathleen Kellogg, Carl
Raggio and Simone Lagomarsino to remain employees of City National (or one of
its subsidiaries) for a period of up to six months following the Effective Time.
City National and the four executive officers of Ventura are currently engaged
in discussions to determine whether they can reach mutually satisfactory terms
for any such employment relationship.
 
    Ventura, Ventura Bank and Frontier Bank have entered into indemnification
agreements with each of the directors and executive officers of Ventura, Ventura
Bank and Frontier Bank. The agreements provide that Ventura, Ventura Bank and
Frontier Bank will indemnify the indemnitee against expenses, judgment, fines,
settlements and other amounts actually and reasonably incurred by the indemnitee
in connection with any threatened or pending proceeding, including any
proceeding brought by or in the right of Ventura, Ventura Bank or Frontier Bank,
by reason of the fact that the indemnitee is or was a director or officer of
such company. The agreements further provide that expenses incurred by the
indemnitee will be paid by Ventura, Ventura Bank or Frontier Bank in advance,
subject to indemnitee's obligation to reimburse the company in the event it is
ultimately determined that the indemnitee is not entitled to indemnification
under the provisions of the agreement.
 
    The Merger Agreement provides that all rights to indemnification now
existing in favor of the directors and officers of Ventura, Ventura Bank and
Frontier Bank as provided in their respective articles of incorporation,
articles of association, bylaws and indemnification agreements in effect as of
the date of the Merger Agreement will survive the Merger and shall continue in
full force and effect. City National further agreed that following the
consummation of the Merger, to the greatest extent permitted by Delaware law and
the organizational documents or Bylaws of City National it would indemnify,
defend and
 
                                       62
<PAGE>
hold harmless individuals who were directors and officers of Ventura, Ventura
Bank and Frontier Bank for any claim or loss arising out of their actions while
a director or officer, and shall pay the expenses, including attorneys fees, of
such individual in advance of the final resolution of any claim, provided such
individual shall first execute an undertaking acceptable to City National to
return such advances in the event it is finally concluded such indemnification
is not allowed under applicable law.
 
EFFECT ON VENTURA EMPLOYEE BENEFIT PLANS
 
    All employees of Ventura or its subsidiaries who become employees of City
National shall be entitled to participate in stock plans, bonus plans and all
other benefit plans of City National on the same basis as other similarly
situated City National employees. Each such Ventura employee will be credited
for eligibility, participation, vesting and accrual purposes with such
employee's respective years of service with Ventura or a subsidiary (or other
prior service credited by Ventura) as though they had been City National
employees, provided, however, that no more than 1,080 hours of sick leave may be
carried over into City National's sick leave program. See also "THE
MERGER--Interests of Certain Persons in the Transaction."
 
    401(K)/EMPLOYEE STOCK OWNERSHIP PLAN.  Ventura adopted the Ventura County
National Bancorp 401(k)/Employee Stock Ownership Plan (the "401(k)/ESOP" or the
"Plan") effective October 1, 1987. The 401(k)/ESOP was amended and restated,
effective October 1, 1989 to conform to certain changes in the Internal Revenue
Code, subsequently amended to incorporate the annual compensation limit, and
further amended and restated, effective January 1, 1989, to incorporate all
prior changes to the 401(k)/ESOP.
 
    The purpose of the 401(k)/ESOP is to provide employees with an ownership
interest in Ventura and to provide supplemental income upon retirement. All
employees of Ventura and its subsidiaries (including Ventura Bank and Frontier
Bank) are eligible to participate in the 401(k)/ESOP upon the attainment of age
21 and the completion of ninety days of service for purposes of making elective
deferrals to the 401(k) portion of the 401(k)/ESOP, and one year of service
(during which employees complete at least 1,000 hours of service) for purposes
of eligibility to receive an allocation of employer matching and/or
discretionary contributions. Directors of Ventura and its subsidiaries and
employees who do not complete at least 1,000 hours of service in a plan year are
not eligible to participate.
 
    The 401(k)/ESOP consists of two programs: the Employee Stock Ownership Plan
("ESOP"), funded in its entirety by contributions from Ventura and its
subsidiaries, and the 401(k) Plan, under which participating employees may make
voluntary pre-tax elective deferrals (not to exceed 12% of the employee annual
compensation) for which matching contributions may be made by Ventura and its
subsidiaries as determined by the Board of Directors. It is intended that the
trust created by the 401(k)/ESOP (the "Trust") will invest the ESOP
contributions and matching contributions under the 401(k) Plan principally in
shares of Ventura Stock. Elective deferrals under the 401(k) Plan are invested
by the trustee for the Trust among investment options (which may include shares
of Ventura Stock) as specified by the participating employees. All Trust assets
are held for the exclusive benefit of participating employees in the
401(k)/ESOP. Contributions by Ventura and its subsidiaries are at the discretion
of their respective Boards of Directors.
 
    Employer contributions to the 401(k)/ESOP are allocated among participating
employees in proportion to their compensation for the plan year. Participating
employees are 100% vested in all voluntary contributions by the employee under
the 401(k) Plan and become vested in contributions and matching contributions
made by Ventura and its subsidiaries under the ESOP and 401(k) portions of the
Plan to the extent of 20% thereof for each year of service, with 100% vesting
after five years of service. The Internal Revenue Service most recently
determined that the 401(k)/ESOP is a "qualified plan" and that the Trust is
exempt from income taxation under the Code by letter dated July 27, 1995.
 
   
    As of the Record Date, the 401(k)/ESOP held 294,919 shares of Ventura Stock,
all of which shares had been allocated to participating employees.
    
 
                                       63
<PAGE>
   
    Each participating employee in the 401(k)/ESOP may instruct the Trustee of
the Plan as to the manner in which the shares of Ventura Stock allocated to his
or her account will be voted at the Meeting. The Trustee will be bound by any
such instructions unless following such instructions would cause the Trustee to
breach one or more of its fiduciary duties to the Plan and the participating
employees as provided in Section 404(a) of ERISA. All allocated shares for which
no voting instructions are received by the Trustee will be voted by the Trustee
on the proposal to approve the principal terms of the Merger Agreement and any
other proposal properly brought before the shareholders at the Meeting in the
same proportion as the aggregate of all participant instructions received by the
Trustee with respect to each such proposal unless doing so would cause the
Trustee to breach one or more of its fiduciary duties to the Plan and the
participating employees as set forth in Section 404(a) of ERISA.
    
 
   
    If the Merger is approved, the participating employees will elect whether
shares held by the 401(k)/ ESOP will be converted into cash, City National
Stock, or a combination of the two. See "THE MERGER--Consideration Payable Upon
Consummation of the Merger" above.
    
 
    Subject to consummation of the Merger, all participating employees will
become 100% vested in their benefits under such Plan, regardless of their length
of employment with Ventura or its subsidiaries. Ventura, Ventura Bank, Frontier
Bank and City National will determine whether to terminate the entire Plan or
only the ESOP portion of the Plan or to merge all or only the 401(K) portion of
the Plan into the City National Corporation Profit Sharing Plan (the "City
National Plan"). If the Plan is merged into the City National Plan, all assets
of the Plan will be transferred into the City National Plan and future
distributions to participating employees will be made in accordance with the
City National Plan.
 
STOCK OPTIONS
 
   
    Ventura currently maintains the Ventura County National Bancorp 1991 Stock
Option Plan (the "Option Plan"). As of the Record Date, options were outstanding
under the Option Plan to acquire 208,616 shares of Ventura Stock at an average
exercise price of $3.365 per share, and of such amount, directors as a group
hold options to acquire in the aggregate 116,116 shares of Ventura Stock, at an
average exercise price of $3.3859 per share.
    
 
   
    Immediately prior to the Effective Time of the Merger, Ventura will pay each
holder of an unexercised option an amount in cash (subject to applicable
withholding tax) equal to the difference between $5.03 and the optionee's
exercise price per share, multiplied by the number of shares subject to option,
or approximately $347,348 in the aggregate for all options outstanding as of the
Record Date. At the Effective Time of the Merger, the Ventura Option Plan will
be terminated and options not exercised or cancelled will be terminated.
    
 
CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
    The following discussion summarizes certain of the material federal income
tax consequences of the Merger. It is intended to provide only a general summary
and does not include a complete analysis of all the potential federal income tax
consequences or consequences that may vary with or are contingent upon
individual circumstances, such as the taxpayer's being subject to certain
special provisions of the Code. This discussion does not address any aspects of
state, local, or foreign tax laws or any federal tax laws other than those
pertaining to income tax.
 
    Neither Ventura nor City National has requested a ruling from the Service
with respect to any of the matters discussed in this summary. Due to the
Service's so-called "comfort rulings" policy concerning corporate
reorganizations, it is unlikely that the Service would be willing to issue a
ruling regarding the Merger.
 
    Manatt, Phelps & Phillips, LLP as Tax Counsel, has advised Ventura that, in
its opinion, the legal issues discussed in this federal income tax summary are
correct in all material respects. However, the
 
                                       64
<PAGE>
summary is not an opinion of Tax Counsel or tax advice and does not in any way
constitute an assurance that the federal income tax consequences discussed
herein will be accepted by the Service or the courts.
 
    It is a condition to the obligations of Ventura to consummate the Merger
that Ventura receive an opinion from its Tax Counsel concluding that the Merger
will qualify as a tax-deferred reorganization within the meaning of Section
368(a) of the Code. The tax consequences discussed below are based on the
assumption that the Merger does so qualify. Ventura has received such an opinion
from its Tax Counsel, subject to confirmation at the Effective Time. The
discussion herein is based on the assumption that Tax Counsel will give its
confirming opinion at the Effective Time that the Merger will constitute a
tax-deferred reorganization within the meaning of Section 368(a) of the Code.
 
    The following summary and the opinion of Tax Counsel are based on certain
assumptions regarding the factual circumstances that will exist at the Effective
Time of the Merger and on certain representations made by Ventura, a 5%
shareholder of Ventura, and City National with respect to the Merger, including
representations regarding actions of City National and certain Ventura
shareholders following the Merger. If any of these factual assumptions or
representations are inaccurate, the tax consequences of the Merger could differ
from those described in this summary and the opinion of Tax Counsel.
 
    The treatment of the Merger as a tax-deferred reorganization will depend
upon, among other things, whether the shareholders of Ventura maintain a
sufficient continuity of stock ownership interest in City National after the
Merger. The Service takes the position for purposes of issuing advance rulings
under Section 368(a)(1)(A) of the Code that the shareholders of the acquired
corporation (i.e., Ventura) must maintain a continuing equity ownership interest
in the acquiring corporation (i.e., City National) equal to at least 50% of the
value of their equity ownership interest in the acquired corporation. The case
law standard is less stringent than the Service's announced advance rulings
standard. The Service's advance rulings standard is not a legal test. Tax
Counsel's opinion relies on the continuity standard under the decided cases
rather than the Service's advance rulings standard. It is anticipated that the
Merger will satisfy both the advance rulings standard and the case law
continuity requirement, but it is possible that sales, exchanges or other
dispositions of City National Stock undertaken by the Ventura shareholders could
disqualify the Merger as a tax-deferred reorganization within the meaning of
Section 368(a) of the Code. In that case, the Merger would constitute a fully
taxable transaction for Ventura and its shareholders. As a result of the Merger,
City National would inherit Ventura's tax liability (if any) resulting from the
Merger.
 
    Subject to the assumptions discussed above, the federal income tax
consequences of the Merger to a shareholder of Ventura will depend on whether
the shareholder receives cash, shares of City National Stock, or both in
exchange for his or her shares of Ventura Stock. This will depend, in part, on
certain elections available to the shareholders. If a shareholder of Ventura
receives cash in exchange for all shares of Ventura Stock actually owned by him
or her, the federal income tax consequences will also depend on whether any
shares of Ventura Stock constructively owned by that shareholder (pursuant to
the constructive ownership rules of Section 318 of the Code) are exchanged for
cash or for shares of City National Stock. If a shareholder of Ventura receives
both cash and shares of City National Stock in exchange for Ventura Stock
actually owned by that shareholder, the federal income tax consequences may also
depend both upon whether he or she already owns any shares of City National
Stock and whether any such stock may be attributed to him or her pursuant to the
constructive ownership rules of Section 318 of the Code. Therefore, a
shareholder of Ventura must take into account the consideration received in
exchange for shares of Ventura Stock actually owned by him or her (including
shares of Ventura Stock owned by him or her that are held on his or her behalf
by brokerage firms, banks or other agents) and may also be required to take into
account (1) the consideration received by certain individuals and entities whose
stock ownership is attributed to that shareholder (as described in "Constructive
Ownership" below) in exchange for their shares of Ventura Stock and (2) any
shares of City National Stock from whatever source of which the shareholder is
the actual owner or constructive owner (as described in "Constructive Ownership"
below).
 
                                       65
<PAGE>
    RECEIPT OF CITY NATIONAL STOCK FOR ALL VENTURA STOCK ACTUALLY OWNED.  A
shareholder of Ventura who receives shares of City National Stock in exchange
for all the shares of Ventura Stock actually owned by that shareholder (without
regard to any cash received in lieu of a fractional share of City National
Stock) will recognize no gain or loss as a result of the Merger (except with
respect to any cash received in lieu of a fractional share). The basis of the
City National Stock received by that shareholder (including any fractional
interests) will be the same as the basis of the shares of the Ventura Stock
exchanged therefor, and the holding period of those shares of City National
Stock will include the holding period of the Ventura Stock surrendered in the
exchange, provided the latter shares were held by the shareholder as a capital
asset. The foregoing result will obtain regardless of whether the shareholder is
treated as owning other shares under the constructive ownership rules described
in "Constructive Ownership" below.
 
    RECEIPT OF CASH FOR ALL VENTURA STOCK ACTUALLY OWNED.  If cash is received
for all shares of Ventura Stock actually owned by a shareholder of Ventura and
either: (1) that shareholder is not treated as owning any additional shares of
Ventura Stock pursuant to the constructive ownership rules of Section 318 of the
Code; or (2) none of the shares of Ventura Stock treated as owned by that
shareholder, pursuant to the constructive ownership rules of Section 318 of the
Code, is exchanged for shares of City National Stock in the Merger, that
shareholder will recognize gain or loss in an amount equal to the difference
between the cash received by the shareholder and the basis for the shares of
Ventura Stock exchanged. That gain or loss will be capital gain or loss if the
shares of Ventura Stock are held as a capital asset at the time of the Merger.
 
    However, if a shareholder of Ventura receives cash for all of the Ventura
Stock actually owned by the shareholder, but some or all of the shares of
Ventura Stock treated as constructively owned by that shareholder (pursuant to
Section 318 of the Code) are exchanged for shares of City National Stock in the
Merger, that shareholder will recognize gain or loss with respect to the Ventura
Stock actually owned by him or her in the manner described in the preceding
paragraph only if the receipt of cash by that shareholder does not have the
effect of a distribution of a dividend under Section 302 of the Code. See
"Impact of Section 302 of the Code" below. If none of the three tests of Section
302 of the Code for sale or exchange treatment (as described below) is
satisfied, a shareholder of Ventura described in this paragraph will be treated
as having received a dividend to the extent of the lesser of the cash received
or the amount of that shareholder's ratable share of Ventura's earnings and
profits (both current and accumulated) through the date of the Merger.
 
    RECEIPT OF BOTH SHARES OF CITY NATIONAL STOCK AND CASH FOR VENTURA STOCK
ACTUALLY OWNED.  A shareholder of Ventura who, in the Merger, receives both
shares of City National Stock and cash (other than cash received in lieu of a
fractional share of City National Stock) in exchange for all of the shares of
Ventura Stock actually owned by that shareholder, will not be permitted to
recognize any loss as a result of the Merger, but will be required to recognize
gain (if any) equal to the lesser of: (1) the amount of cash so received (other
than cash received in lieu of a fractional share of City National Stock); and
(2) the gain realized (i.e., the amount by which the sum of the amount of cash
so received and the market price on the date of the Merger of the shares of City
National Stock received, including any fractional interest, exceeds that
shareholder's basis for the shares of Ventura Stock surrendered). The
characterization of any such gain will depend upon whether the receipt of cash
by that shareholder has the effect of a distribution of a dividend under Section
302 of the Code with respect to City National Stock. See "Impact of Section 302
of the Code" below. In general, Section 302 of the Code sets forth three tests
for determining the character of the gain. Provided that any one of the three
tests for sale or exchange treatment is satisfied, the gain so recognized will
be capital gain if that shareholder's shares of Ventura Stock, and hence City
National Stock, are held as a capital asset at the time of the Merger. If none
of the three sale or exchange tests is satisfied, the entire amount of gain
required to be recognized by that shareholder will be treated as a dividend to
the extent of the shareholder's ratable share of the accumulated earnings and
profits of Ventura (or, possibly, the accumulated earnings and profits of City
National) and any remaining amount of recognized gain will be characterized in
accordance with the preceding sentence. The tax basis of the
 
                                       66
<PAGE>
shares of City National Stock received by such a shareholder will be the same as
the basis of the shares of Ventura Stock surrendered in exchange therefor,
increased by the amount recognized as either dividend income or capital gain,
and decreased by the amount of cash received, other than cash received in lieu
of a fractional share of City National Stock, and by any basis allocable to such
a fractional share of City National Stock. The holding period of the shares of
City National Stock received by that shareholder in the Merger will include the
holding period of the shares of Ventura Stock exchanged therefor, provided the
shares of Ventura Stock are held as a capital asset at the time of the Merger.
 
    IMPACT OF SECTION 302 OF THE CODE.  As described in the preceding section
and below, the manner in which Section 302 of the Code is applied depends upon
whether a Ventura shareholder receives only cash or both cash and shares of City
National Stock in exchange for the shares of Ventura Stock actually owned by
that shareholder. The receipt of cash by a shareholder of Ventura who receives
only cash will be considered to be in connection with a sale or exchange and not
to have the effect of a distribution of a dividend under Section 302 only if,
after giving effect to the constructive ownership rules of Section 318 of the
Code and, if applicable, the exception thereto provided in Section 302(c)(2) of
the Code, the receipt of that cash is: (1) "not essentially equivalent to a
dividend," (2) a "substantially disproportionate redemption" with respect to
that shareholder, or (3) a "complete termination of the shareholder's interest"
in all the shares of Ventura Stock actually and constructively owned by that
shareholder.
 
    The determination whether any of the three tests of Section 302 for sale or
exchange treatment is satisfied is made by treating the exchange as if all the
shares of Ventura Stock actually and constructively owned by the shareholder had
been exchanged solely for shares of City National Stock, and the shares of City
National Stock that were not in fact received had then been redeemed by City
National for cash (the "hypothetical redemption of City National Stock"). The
rules of Section 302 will then be applied by comparing a shareholder's
hypothetical stock ownership in City National before the hypothetical redemption
of City National Stock with that shareholder's stock ownership in City National
after the Merger.
 
    Whether the receipt of cash by a shareholder of Ventura will be "not
essentially equivalent to a dividend" depends on the facts and circumstances of
the individual shareholder of Ventura. The receipt of cash by a Ventura
shareholder in exchange for the shares of Ventura Stock actually owned by that
shareholder should not be taxable as a dividend if the shareholder's relative
stock interest in City National is minimal, the shareholder exercises no control
over City National's affairs, and the hypothetical redemption of City National
shares described above causes the shareholder to undergo some reduction in
equity interest in City National (taking into account the hypothetical
redemption of City National Stock) in relation to all City National shareholders
taken as a group. It is not clear what constitutes a "minimal" stock interest
for this purpose, nor how much reduction in relative equity interest is
required. Because of the uncertainty in this area, shareholders are strongly
urged to consult their own tax advisors as to whether their receipt of cash
qualifies for capital gain treatment under this test.
 
    Whether the receipt of cash by a shareholder of Ventura will constitute a
"substantially disproportionate redemption" within the meaning of Section 302 of
the Code is determined by the application of certain numerical tests. If cash is
received for shares of Ventura Stock actually owned by a shareholder, those
numerical tests are applied as follows: First, immediately, after the exchange,
the shareholder must own, both actually and constructively, less than 50% of the
total combined voting power of all classes of City National Stock entitled to
vote. Second, the ratio that the voting stock of City National owned, both
actually and constructively, by the shareholder immediately after the exchange
bears to all the voting stock of City National outstanding at that time must be
less than 80% of the ratio that the voting stock of City National owned, both
actually and constructively, by the shareholder immediately before the
hypothetical redemption of City National Stock described above bears to all the
voting stock of City National outstanding at that time. In making the
calculations required to determine whether the hypothetical redemption of City
National Stock is "substantially disproportionate" the constructive ownership
rules described below apply. See "Constructive Ownership" below.
 
                                       67
<PAGE>
    The receipt of cash by a shareholder of Ventura will be a "complete
termination of interest" only if the shareholder receives cash for all of the
shares of Ventura Stock actually and constructively owned by that shareholder at
the time of the Merger. For these purposes, the attribution rules of Section 318
of the Code will apply as described below. However, Section 302(c)(2) provides
that, for the purpose of determining whether there is a "complete termination of
interest," the family attribution rules of Section 318(a)(1) of the Code
(described in "Constructive Ownership" below) will not apply if certain
conditions are met. If those conditions are met, a Ventura shareholder will not
be deemed to own shares of Ventura Stock owned or deemed to be owned by family
members for the purpose of determining whether there is a complete termination
of that shareholder's interest.
 
    The Agreement and Plan of Merger permits Ventura shareholders to make
certain elections regarding their preferred mix of cash and City National Stock
to be received in the Merger. In planning which election to make, shareholders
of Ventura should take into account the rules regarding Section 302 of the Code
described above. The factors determining whether a particular shareholder will
obtain sale or exchange treatment (as opposed to dividend treatment) with
respect to any cash received must be analyzed on a shareholder-by-shareholder
basis. In addition, the relative benefits of receiving sale or exchange
treatment (as opposed to dividend treatment) with respect to any cash received
must be determined and weighed on a shareholder-by-shareholder basis. In
planning for such an election, each shareholder should consult with his or her
own tax advisor.
 
    CONSTRUCTIVE OWNERSHIP.  Under Section 318 of the Code, a shareholder of
Ventura will be deemed to own Ventura Stock that is owned or deemed to be owned
by certain members of his family and other related parties including, for
example, certain entities in which the shareholder has a direct or indirect
interest (including partnerships, estates, trusts and corporations) as well as
shares of Ventura Stock that the shareholder (or a related person) has the right
to acquire upon exercise of an option or conversion right held by the
shareholder (or a related person). Similarly, a shareholder of City National,
including a former shareholder of Ventura after the Merger, will be deemed to
own City National Stock that is owned or deemed to be owned as described in the
preceding sentence, including any City National Stock received in exchange for
Ventura Stock as a result of the Merger. Because application of these
constructive ownership rules could affect the application of Section 302 to a
shareholder of Ventura, each shareholder should consult his or her own tax
advisor with respect to the application of the constructive ownership rules to
his or her particular circumstances prior to making an election pursuant to the
terms of the Merger.
 
    FRACTIONAL SHARES.  Any shareholder of Ventura who receives cash in lieu of
a fractional share of City National Stock will be treated as if that shareholder
received the fractional share of City National Stock in the Merger, which
fractional share was then redeemed by City National.
 
    OTHER CONSIDERATIONS APPLICABLE TO SHAREHOLDERS OF VENTURA.  Shareholders of
Ventura will be required to provide their social security numbers or their
taxpayer identification numbers or, in some circumstances, certain other
information to the Exchange Agent in order to avoid the "backup withholding"
requirements that might otherwise apply under the Code.
 
    SHARES ISSUED IN CONNECTION WITH STOCK OPTIONS OR THE PERFORMANCE OF
SERVICES.  The preceding discussion of federal income tax consequences may not
be applicable to a shareholder of Ventura who acquires shares of Ventura Stock:
(1) pursuant to the exercise of any incentive stock option that was granted less
than two years prior to the date of the Merger; (2) pursuant to the exercise of
an incentive stock option that was exercised less than one year prior to the
date of Merger; or (3) in connection with the performance of services where the
shares of Ventura Stock continue to be subject to a "substantial risk of
forfeiture" (or are substantially non-vested), as of the date of the Merger.
Such a shareholder of Ventura may be treated as having received compensation
(taxable as ordinary income) as a result of the Merger. Accordingly, any such
shareholder should consult his or her own tax advisor with respect to the
federal income tax consequences of the Merger.
 
                                       68
<PAGE>
    The foregoing discussion of the expected federal income tax consequences of
the Merger is based on current authorities. There is no assurance that
legislative or administrative changes or court decisions may not be forthcoming
that would significantly change these expected consequences. Any such changes
may or may not be retroactive with respect to transactions prior to the date of
those changes.
 
    THE SUMMARY FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR
GENERAL INFORMATION ONLY. IT DOES NOT CONSTITUTE TAX ADVICE OR AN OPINION OF TAX
COUNSEL. EACH SHAREHOLDER SHOULD CONSULT HIS OR HER OWN TAX ADVISOR AS TO THE
SPECIFIC TAX CONSEQUENCES OF THE MERGER APPLICABLE TO HIM OR HER, INCLUDING THE
APPLICATION AND EFFECT OF FEDERAL, STATE, LOCAL AND OTHER TAX LAWS.
 
ACCOUNTING TREATMENT
 
    The Merger will be accounted for by City National under the purchase method
of accounting in accordance with Accounting Principles Board Opinion No. 16,
"Business Combinations," as amended. Under this method of accounting, the
purchase price will be allocated to assets acquired and liabilities assumed
based on their estimated fair values at the Closing. Income of the combined
company will not include income (or loss) of Ventura prior to the Closing. See
"PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION."
 
EXPENSES
 
    The Merger Agreement provides that each party will pay its own expenses in
connection with the Merger Agreement; provided, however, that the costs and
expenses of printing and mailing the Proxy Statement/Prospectus will be borne by
City National, unless the Merger does not occur (other than due to a termination
of the Merger Agreement arising out of a material breach of the Merger Agreement
by City National or Ventura), in which event such costs and expenses will be
borne equally by City National and Ventura. All filing and other fees paid to
the SEC in connection with the Merger will be borne by City National.
 
                           CERTAIN RELATED AGREEMENTS
 
SHAREHOLDERS' AGREEMENT
 
   
    In connection with the Merger Agreement, each of the directors of Ventura,
together holding an aggregate of 1,291,686 shares of Ventura Stock (or
approximately 13% of the shares of Ventura Stock outstanding on the Record
Date), have entered into a Shareholders' Agreement with City National dated as
of September 15, 1996 (the "Shareholders' Agreement"). Pursuant to the
Shareholders' Agreement, such persons have agreed to vote or cause to be voted
all shares of Ventura Stock owned or acquired by them, in favor of the Merger
and the Merger Agreement and the other matters contemplated by the Merger
Agreement. In addition, such persons have agreed to vote or cause to be voted
all of the shares of Ventura Stock (1) against any action or agreement that
would result in a breach in any material respect of any covenant, representation
or warranty or any other obligation or agreement of Ventura under the Merger
Agreement or the Option Agreement, dated as of September 15, 1996, between City
National and Ventura (the "Option Agreement"); and (2) except with the prior
written consent of City National, against the following actions (other than the
Merger and the transactions contemplated by the Merger Agreement): (A) any
extraordinary corporate transactions, such as a merger, consolidation or other
business combination involving Ventura or its subsidiaries; (B) any sale, lease
or transfer of a material amount of the assets of Ventura or its subsidiaries;
(C) any change in the majority of the board of Ventura (D) any material change
in the present capitalization of Ventura; (E) any amendment of the Ventura
Articles (as hereinafter defined); (F) any other material change in Ventura's
corporate structure or business; or (G) any other action which is intended, or
could reasonably be expected, to impede, interfere with, delay,
    
 
                                       69
<PAGE>
postpone, discourage or materially adversely affect the contemplated economic
benefits to City National of the Merger or the transactions contemplated by the
Merger Agreement or the Option Agreement. Such persons also have agreed not to
enter into any agreement or understanding with any person or entity to vote or
give instructions after the date that the Shareholders' Agreement terminates in
any manner inconsistent with such persons' obligation to vote in accordance with
the above-referenced guidelines.
 
    Such persons also have agreed not to (1) sell, transfer, assign or otherwise
dispose of any of their shares of Ventura Stock without the prior written
consent of City National, other than shares of Ventura Stock sold or surrendered
to pay the exercise price of any stock options or to pay taxes or satisfy
Ventura's withholding obligations with respect to any taxes resulting from such
exercise or (2) pledge, mortgage or encumber such shares of Ventura Stock.
 
    In addition, such persons also have agreed (1) that they will not directly
or indirectly solicit any inquiries or proposals from any person relating to any
proposal or transaction for the disposition of the business or assets of Ventura
or any of its subsidiaries, or the acquisition of voting securities of Ventura
or any subsidiary of Ventura or any business combination between Ventura and any
person other than City National and (2) to use their best efforts to maintain
such persons' (including their affiliates') banking relationship with Ventura
Bank and/or Frontier after the Merger and after the occurrence of a Bank Merger,
with City National Bank, for a period of at least three years in a manner
consistent with past practice.
 
    Pursuant to the Shareholders' Agreement, City National has agreed to
establish a Ventura County Board of Advisors, or similar advisory and community
liaison group, in order that Ventura Bank and, following the Bank Merger, City
National Bank, will be able to continue visibility in Ventura County and to
provide service to the community. City National's current intention is that one
or more former directors of Ventura will serve initially on such board of
advisors, and each director has agreed to give due consideration to a request by
City National that he or she serve on such body.
 
OPTION AGREEMENT
 
    GENERAL.  Concurrently with the execution and delivery of the Merger
Agreement, and as a condition and inducement thereto, City National and Ventura
entered into the Option Agreement, pursuant to which Ventura granted City
National an option to purchase up to 1,836,516 shares of the outstanding Ventura
Stock (or such other number of shares of Ventura Stock as represent 19.9% of the
then outstanding Ventura Stock) at a price per share of $3.93. The consummation
of a purchase or a repurchase (as described below) pursuant to the Stock Option
Agreement may be subject to, among other things obtaining any required
regulatory approvals.
 
    The following is a summary of certain provisions of the Option Agreement
which is attached hereto as Annex D to this Proxy Statement/Prospectus and is
incorporated herein by reference. The following summary is qualified in its
entirety by reference to the Option Agreement.
 
    EXERCISE OF THE OPTION.  The option is exercisable only upon the occurrence
of certain specified events (each an "Exercise Event") inconsistent with the
consummation of the Merger pursuant to the Merger Agreement. These include, but
are not limited to:
 
        (1) a merger or consolidation of Ventura or its subsidiaries or a
    disposition of 50% or more of their consolidated assets;
 
        (2) the issuance, sale or disposition of securities representing 20% or
    more of the voting power of Ventura or its subsidiaries;
 
        (3) the acquisition by any person or group of beneficial ownership of,
    or the right to acquire beneficial ownership of, 20% or more of the
    outstanding shares of Ventura Stock;
 
                                       70
<PAGE>
        (4) the public authorization, recommendation or endorsement by Ventura
    of, or the entering into by Ventura of an agreement to effect, any of the
    above-listed transactions; or
 
        (5) the termination by Ventura of the Merger Agreement pursuant to the
    exercise of the Ventura Board of Directors' fiduciary duties.
 
If the Merger Agreement is terminated in a manner that does not immediately
render the option exercisable, the option may thereafter become exercisable upon
the occurrence of an Exercise Event, provided the option has not expired.
 
    EXPIRATION.  The right to exercise the option expires under various
circumstances, including, but not limited to (1) termination of the Merger
Agreement by mutual consent, (2) termination of the Merger Agreement by Ventura
if the Final City National Stock Price is less than $13.90, or (3), provided an
Exercise Event or certain preliminary acquisition events have not occurred,
termination of the Merger Agreement due to a material breach thereof, the
failure to obtain Regulatory Approval or shareholder approval or the failure to
consummate the Merger by May 31, 1997, or termination by City National due to a
withdrawal of the endorsement of the Merger Agreement by the Ventura Board. The
option also expires eighteen months following the date it first becomes
exercisable or following any termination of the Merger Agreement other than
pursuant to the provisions summarized in the previous sentence.
 
    LIMITATION ON SPREAD VALUE.  City National may not realize Spread Value (as
described below) in excess of $2,000,000 upon the exercise of the option. In the
event the Spread Value exceeds $2,000,000 the number of shares of Ventura Stock
which City National is entitled to purchase will be reduced to the extent
required such that the Spread Value following such reduction is equal to or less
than $2,000,000.
 
    "Spread Value" is precisely defined in the Option Agreement, but is intended
to approximate the excess of the market value of Ventura Stock (based on Nasdaq
closing prices of Ventura Stock just prior to the date of exercise) over the
option exercise price of $3.93 per share of Ventura Stock.
 
    ADJUSTMENT OF NUMBER OF SHARES.  The number and type of securities subject
to the options and the purchase price of the shares of Ventura Stock are subject
to adjustment upon any change in the Ventura Stock by reason of dividend, stock
split, recapitalization, combination, exchange of shares or other similar
transactions or events such that City National will receive (upon exercise of
the option) the same number and class of securities as if the option had been
exercised immediately prior to the occurrence of such transaction or event. The
number of shares of Ventura Stock subject to the option will also be adjusted in
the event Ventura issues additional shares of Ventura Stock, such that the
number of shares of Ventura Stock subject to the option represents 19.9% of
Ventura's Stock then outstanding.
 
    SUBSTITUTE OPTION.  In the event of certain mergers or consolidations
involving Ventura or its subsidiaries or the sale or transfer of substantially
all of Ventura's assets, City National has the right to cause the option to
convert into or be exchanged for a substitute option. This substitute option
would be subject to exercise by City National and repurchase by the issuer at
the request of City National, at prices, and subject to conditions, specified in
the Option Agreement.
 
    REPURCHASE AT THE OPTION OF CITY NATIONAL.  During the 12 month period
following specified "Repurchase Events," City National has the right to require
Ventura to repurchase the option and, to the extent permitted by the California
Code, all shares of Ventura Stock purchased by City National pursuant to a
previous exercise of the option. A "Repurchase Event" under the Option Agreement
includes: (i) the acquisition by any person or group of beneficial ownership, or
the right to acquire beneficial ownership, of 50% or more of the
then-outstanding shares of Ventura Stock, (ii) the consummation of a transaction
causing a substitute option to be issued, or (iii) following an Exercise Event,
the receipt by City National of notice that regulatory approval required for the
exercise of the option and purchase of the option shares will not be issued or
granted.
 
                                       71
<PAGE>
    Any repurchase will be at a price specified in the Option Agreement as the
"Repurchase Consideration." Generally, the Repurchase Consideration equals the
sum of (1) the option price paid by City National upon exercises of the option,
(2) the excess of the Applicable Price over $3.93, multiplied by the number of
shares of Ventura Stock with respect to which the option has not been exercised
or with respect to which the option has been exercised but City National still
has beneficial ownership of the shares of Ventura Stock, multiplied by the
number of all of such shares. The portion of the Repurchase Consideration in
excess of the exercise price paid by City National is limited to $2,000,000.
 
    Under the Option Agreement, the "Applicable Price" generally refers to the
highest price per share of Ventura Stock (1) paid by another party in certain
Repurchase Events, (2) received by Ventura shareholders in any transaction which
caused a substitute option to be issued, or (3) in the market during a specified
period prior to City National's exercise of its repurchase right. In the event
of a sale of less than all of Ventura's assets, "Applicable Price" is defined
with respect to market value of Ventura's remaining assets.
 
    REGISTRATION RIGHTS.  City National has certain rights to require
registration of any shares of Ventura Stock purchased pursuant to the Option
Agreement under the securities laws if necessary to enable City National to sell
such shares.
 
    EFFECT OF OPTION AGREEMENT.  The Option Agreement is intended to increase
the likelihood that the Merger will be consummated on the terms set forth in the
Merger Agreement. Consequently, certain aspects of the Option Agreement may have
the effect of discouraging persons who might now or prior to the Effective Time
be interested in acquiring all of or a significant interest in Ventura from
considering or proposing such an acquisition, even if such persons were prepared
to offer higher consideration per share for Ventura Stock then the consideration
set forth in the Merger Agreement.
 
RESALE OF CITY NATIONAL STOCK
 
   
    The shares of City National Stock issued pursuant to the Merger Agreement
will be freely transferable under the Securities Act except for shares issued to
any shareholder who may be deemed to be an "affiliate" of Ventura for purposes
of Rule 145 under the Securities Act as of the date of the Special Meeting.
Affiliates may not sell their shares of City National Stock acquired in
connection with the Merger except pursuant to an effective registration
statement under the Securities Act covering such shares or in compliance with
Rule 145 under the Securities Act or another applicable exemption from the
registration requirements of the Securities Act. Persons who may be deemed to be
affiliates of Ventura generally include individuals or entities that control,
are controlled by or are under common control with Ventura and may include
certain officers and directors of Ventura as well as principal shareholders of
Ventura.
    
 
    Certain persons who Ventura believes to be affiliates of Ventura have
entered into an agreement providing that such persons will not sell, assign,
transfer or otherwise dispose of, or offer to sell, transfer or otherwise
dispose of the City National Stock to be received by such persons in the Merger
except (1) in compliance with the applicable provisions of the Securities Act
and the rules and regulations thereunder or (2) in a transaction that, in the
opinion of independent counsel reasonably satisfactory to City National, is
exempt from registration under the Act.
 
                          DESCRIPTION OF CAPITAL STOCK
 
    The following summary does not purport to be complete and is subject in all
respects to the applicable provisions of the Delaware Code and the City National
Certificate of Incorporation. For a fuller discussion of certain rights
associated with the City National Stock, see "Comparison of Rights of Holders of
City National Stock and Ventura Stock."
 
                                       72

COMMON STOCK
 
    City National has 75,000,000 authorized shares of Common Stock, of which
approximately 43,826,808 were issued and outstanding as of November 8, 1996 and
an additional 3,833,498 shares were subject to stock options. City National
Stock is traded on the NYSE under the symbol "CYN."
 
   
    The holders of City National Stock are entitled to one vote per share on all
matters requiring stockholder action. The City National Certificate does not
permit cumulative voting for directors. The holders of City National Stock have
no preemptive or other subscription rights and there are no redemption, sinking
fund or conversion privileges applicable thereto. The holders of City National
Stock are entitled to receive dividends as and when declared by the Board of
Directors out of funds legally available therefor, subject to any restrictions
by its regulators. Upon liquidation, dissolution or winding up of City National,
holders of City National Stock are entitled to share ratably in all assets
remaining after payment of liabilities. All outstanding shares of City National
Stock are fully paid and nonassessable.
    
 
    The registrar and transfer agent for City National Stock is Continental
Stock Transfer Trust Company.
 
PREFERRED STOCK
 
   
    City National has 5,000,000 authorized shares of preferred stock, of which
none were issued and outstanding as of November 5, 1996. The City National
Certificate provides that the terms, rights and preferences of any preferred
stock issued in the future, including dividend rates, conversion prices, voting
rights, redemption prices, maturity dates, liquidation preference and similar
matters, are to be determined by City National's Board of Directors at the time
such issuance is approved. Management does not presently know whether any shares
of preferred stock will actually be issued or, if issued, what the terms, rights
and preferences thereof will be. Under Delaware law, however, the holders of
such preferred stock will not have any preemptive rights with respect to the
future issuance of shares of common or preferred stock, unless the City National
Certificate is amended to provide for such rights. Depending on the terms,
rights and preferences thereof, the issuance of any shares of preferred stock
may have the effect of diluting the percentage of stock ownership and voting
rights of other shareholders of City National.
    
 
SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW
 
   
    Section 203 ("Section 203") of the Delaware Code prevents a Delaware
corporation from engaging in a "Business Combination" (defined to include a
variety of transactions, including mergers, as set forth below) with an
"Interested Stockholder" (generally defined as a person with 15% or more of a
corporation's outstanding voting stock) for three years following the date such
person became an Interested Stockholder unless: (1) before such person became an
Interested Stockholder, the board of directors of the corporation approved
either the Business Combination or the transaction in which the Interested
Stockholder became an Interested Stockholder; (2) upon consummation of the
transaction which resulted in the Interested Stockholder becoming an Interested
Stockholder, the Interested Stockholder owned at least 85% of the voting stock
of the corporation outstanding at the time the transaction commenced (excluding
stock held by directors who are also officers and employee stock ownership plans
in which employee participants do not have the right to determine confidentially
whether shares held subject to the plan will be tendered in a tender or exchange
offer); or (3) following the date on which such person became an Interested
Stockholder, the Business Combination is (x) approved by the board of directors
of the corporation and (y) authorized at a meeting of stockholders by the
affirmative vote of at least 66 2/3% of the outstanding voting stock of the
corporation not owned by the Interested Stockholder.
    
 
    Under Section 203, the restrictions described above apply to City National
unless, among other things, (1) by the affirmative vote of a majority of shares
entitled to vote, it adopts an amendment to its certificate of incorporation or
bylaws expressly electing not to be governed by Section 203 (such an amendment
would not be effective until 12 months after its adoption and would not apply to
any Business Combination between City National and any person who became an
Interest Stockholder on or prior to such adoption);
 
                                       73
<PAGE>
or (2) no class of City National's voting stock is (x) listed on a national
securities exchange, (y) authorized for quotation on an inter-dealer quotation
system of a registered national securities association or (z) held of record by
more than 2,000 stockholders (unless any of the foregoing results from action
taken, directly or indirectly, by an Interested Stockholder or from a
transaction in which a person becomes an Interested Stockholder).
 
    A Business Combination is defined in Section 203 as (1) a merger or
consolidation; (2) any sale, lease, exchange, mortgage, pledge, transfer or
other disposition of assets having an aggregate market value equal to 10% or
more of the aggregate market value of either all assets of the corporation
determined on a consolidated basis or all the outstanding stock of a
corporation; (3) any transaction which results in the issuance or transfer by
the corporation, or by certain subsidiaries thereof, of any of its stock to the
Interested Stockholder, except pursuant to (a) the exercise, exchange or
conversion of securities exercisable for, exchangeable for or convertible into
stock of the corporation of any subsidiary which were outstanding prior to the
time the stockholder became an Interested Stockholder or (b) a transaction which
effects a pro rata distribution to all stockholders of the corporation; (4) any
transaction involving the corporation or certain subsidiaries thereof which has
the effect of increasing the proportionate share of the stock of any class or
series, or securities convertible into the stock of any class or series, of the
corporation or any such subsidiary which is owned directly or indirectly by the
Interested Stockholder (except as a result of immaterial changes due to
fractional share adjustment); or (5) any receipt by the Interested Stockholder
of the benefit (except proportionately as a stockholder of such corporation) of
any loans, advances, guarantees, pledges or other financial benefits provided by
or through the corporation.
 
CHARTER AND BYLAW PROVISIONS
 
    Nominations for the election of directors of City National may be made by
the Board of Directors or by any stockholder entitled to vote for the election
of directors. Stockholders intending to nominate a director candidate for
election must deliver written notice thereof to the Secretary of City National
not later than 60 days in advance of such meeting. Such notice must set forth
certain information concerning such stockholder and the stockholder's
nominee(s).
 
    The City National Certificate provides that the City National Board of
Directors consists of three classes. The directors in each class serve on the
City National Board of Directors for approximately three years each.
Notwithstanding the foregoing, the directors who currently serve in class one
will serve through the 1997 City National shareholders' meeting, the directors
who currently serve in class two will serve through the 1998 City National
shareholders' meeting and the directors who currently serve in class three will
serve through the 1999 City National shareholders' meeting.
 
    The annual meeting of stockholders is required to be held each year on the
third Tuesday in April or at such other date designated by the Board of
Directors. Under City National's Bylaws, a special meeting of stockholders may
be called only by the President of City National or by a majority of the Board
of Directors.
 
   
    The City National Certificate requires the approval of the holders of at
least 70% of the outstanding Common Stock of City National for certain "Business
Combinations" between City National or any subsidiary and a "Restricted Person"
or its affiliates. Such business combinations include the sale or other
disposition of all, substantially all, or any substantial part of the assets or
business of City National or its subsidiaries; the purchase or other acquisition
of all, substantially all, or any substantial part of the assets or business of
another person; a merger or consolidation; any reclassification of securities or
recapitalization designed to decrease the holders of any class of City
National's voting securities if, immediately thereafter, a Restricted Person
will be the owner of more than 35% of any such class; and the issuance of voting
securities, or rights, warrants or options to acquire any such securities of
City National or a subsidiary, to a Restricted Person. The foregoing stockholder
approval is not required for any business combination approved by the Board of
Directors (1) at a time when such other party was not a restricted
    
 
                                       74
<PAGE>
Person or (2) in advance by the affirmative votes of at least the number of
directors that is one less than the entire authorized number of directors of
City National, at a meeting called for such purpose. A "Restricted Person" is
any entity or group which, during any period of 12 consecutive months, directly
or indirectly acquired more than 5% of the shares of any class of voting
security of City National, except if the transaction in which such securities
were acquired was approved in advance by 66 2/3% of the Board of Directors. A
party ceases to be a Restricted Person at the end of 24 months following the
most recent month in which such securities were acquired which, together with
all other securities acquired in the immediately preceding 11 months, aggregated
more than 5% of the outstanding voting securities.
 
    Under Delaware law, a certificate of incorporation can be amended by a
majority of shares entitled to vote thereon, except as the certificate of
incorporation otherwise provides or if the amendment relates to a provision
requiring a greater vote. The foregoing provision contained in the Certificate
of Incorporation of City National with respect to the requirements for a 70%
stockholder vote in certain business combinations can be repealed or amended
only with the approval of the holders of 70% of the outstanding City National
Stock at a meeting called for such purpose, excluding City National Stock owned
or controlled by a "Restricted Person" or its affiliates.
 
    The foregoing provisions of the City National Certificate, the Bylaws and
Section 203 of the Delaware Code have certain anti-takeover effects. The
provisions help ensure that the Board of Directors, if confronted by a surprise
proposal from a third party, will have sufficient time to review the proposal
and alternatives to the proposal. In addition, the provisions help to insure
that the holders of City National's stock are fairly treated in a multi-step
acquisition.
 
    The provisions are intended to encourage persons seeking to acquire control
of City National to initiate such an acquisition through arms-length
negotiations with City National's Board of Directors. The provisions may have
the effect of discouraging a third party from making a tender offer or otherwise
attempting to attain control of City National, even through such an attempt
might be beneficial to City National and its stockholders.
 
LIMITATION ON DIRECTOR'S LIABILITY
 
   
    City National has entered into indemnification agreements with certain
officers and directors of City National which provide that City National agrees
to indemnify and hold harmless such officer or director to the fullest extent
permissible under its Certificate of Incorporation, Bylaws and applicable law.
The indemnification agreements provide that rights granted thereunder cannot be
eliminated or lessened by amendment to the City National Certificate or Bylaws.
    
 
   
    In addition, the City National Certificates and City National Bank's
articles of association provide that, to the fullest extent permitted by the
Delaware Code and, in the case of City National Bank, except as prohibited by
rules of the OCC, a director of City National or City National Bank shall not be
liable to City National or City National Bank or their respective stockholders
for monetary damages for breach of fiduciary duty as a director. The Delaware
Code currently provides that a director may be relieved of liability for a
breach of fiduciary duty (including acts constituting gross negligence), except
under certain circumstances, including breach of the director's duty of loyalty
to a corporation or its stockholders, acts or omissions not in good faith or
involving intentional misconduct or a knowing violation of law, unlawful payment
of a dividend or unlawful stock purchase or redemption or any transaction from
which the director derived an improper personal benefit.
    
 
                               DISSENTERS' RIGHTS
 
RIGHTS OF DISSENTING SHAREHOLDERS
 
    Because Ventura Stock is traded on Nasdaq and listed on the list of OTC
margin stocks issued by the Board of Governors of the Federal Reserve System,
dissenters' rights will be available to the shareholders
 
                                       75
<PAGE>
of Ventura only if the holders of five percent (5%) or more of Ventura Stock
make a written demand upon Ventura for the purchase of dissenting shares in
accordance with Chapter 13 ("Chapter 13") of the California Code. If this
condition is satisfied and the Merger is consummated, shareholders of Ventura
who dissent from the Merger by complying with the procedures set forth in
Chapter 13 would be entitled to receive an amount equal to the fair market value
of their shares as of September 13, 1996, the last trading day before the public
announcement of the Merger. The high, low and closing sales prices for Ventura
Stock on September 13, 1996 were $3.75, $3.50 and $3.625, respectively. A copy
of Chapter 13 of the California Code is attached hereto as Appendix B and should
be read for more complete information concerning dissenters' rights, THE
REQUIRED PROCEDURE SET FORTH IN CHAPTER 13 OF THE CALIFORNIA CODE MUST BE
FOLLOWED EXACTLY OR ANY DISSENTERS' RIGHTS MAY BE LOST. The information set
forth below is a general summary of dissenters' rights as they apply to Ventura
shareholders and is qualified in its entirety by reference to Appendix B.
 
    In order to be entitled to exercise dissenters' rights, a shareholder of
Ventura must vote "AGAINST" the Merger. Thus, any shareholder who wishes to
dissent and executes and returns a proxy in the accompanying form must specify
that his or her shares are to be voted "AGAINST" the Merger. If the shareholder
returns a proxy without voting instructions or with instructions to vote "FOR"
the Merger, his or her shares will automatically be voted in favor of the Merger
and the shareholder will lose any dissenters' rights. In addition, if the
shareholder abstains from voting his or her shares, the shareholder will lose
his or her dissenters' rights.
 
    Furthermore, in order to preserve his or her dissenters' rights, a
shareholder must make a written demand upon Ventura for the purchase of
dissenting shares and payment to such shareholder of their fair market value,
specifying the number of shares held of record by such shareholder and a
statement of what the shareholder claims to be the fair market value of those
shares as of September 13, 1996. Such demand must be addressed to Ventura County
National Bancorp, 500 Esplanade Drive, Oxnard, California 93030; Attention:
Simone Lagomarsino, and must be received by Ventura not later than the date of
the Meeting. A vote "Against" the Merger does not constitute such written
demand.
 
    If the holders of five percent (5%) or more of the outstanding shares of
Ventura Stock have submitted a written demand for Ventura to purchase their
shares, these demands are received by Ventura on or before the date of the
Meeting and the Merger is approved by the shareholders, Ventura will have ten
days after such approval to send to those shareholders who have voted against
the approval of the Merger written notice of such approval accompanied by a copy
of Chapter 13 of the California Code, a statement of the price determined by
Ventura to represent the fair market value of the dissenting shares as of
September 13, 1996, and a brief description of the procedure to be followed if a
shareholder desires to exercise dissenters' rights. Within 30 days after the
date on which the notice of the approval of the Merger is mailed, the dissenting
shareholder must surrender to Ventura at the office designated in the notice of
approval, the certificates representing the dissenting shares to be stamped or
endorsed with a statement that they are dissenting shares or to be exchanged for
certificates of appropriate denomination so stamped or endorsed. Any shares of
Ventura Stock that are transferred prior to their submission for endorsement
lose their status as dissenting shares.
 
    If Ventura and the dissenting shareholder agree that the surrendered shares
are dissenting shares and agree upon the price of the shares, the dissenting
shareholder will be entitled to the agreed price with interest thereon at the
legal rate on judgments from the date of the agreement. Payment of the fair
market value of the dissenting shares shall be made within 30 days after the
amount thereof has been agreed upon or 30 days after any statutory or
contractual conditions to the Merger have been satisfied, whichever is later,
subject to the surrender of the certificates therefor, unless provided otherwise
by agreement.
 
    If Ventura denies that the shares surrendered are dissenting shares, or
Ventura and the dissenting shareholder fail to agree upon a fair market value of
such shares of Ventura Stock, then the dissenting shareholder of Ventura must,
within six months after the notice of approval is mailed, file a complaint in
 
                                       76
<PAGE>
the Superior Court of the proper county requesting the court to make such
determinations or intervene in any pending action brought by any other
dissenting shareholder. If the complaint is not filed or intervention in a
pending action is not made within the specified six-month period, the
dissenters' rights are lost. If the fair market value of the dissenting shares
is at issue, the court will determine, or will appoint one or more impartial
appraisers to determine, such fair market value.
 
    A dissenting shareholder may not withdraw his or her dissent or demand for
payment unless Ventura consents to such withdrawal.
 
   
    In the event a person who makes a timely written demand for purchase and
votes against the Merger subsequently submits a Letter of Transmittal before the
Election Deadline, he or she will be deemed to have waived his or her
dissenters' rights, and his or her shares will be converted into City National
Stock or cash or both in accordance with the instructions given in the Effective
Election Statement.
    
 
FEDERAL INCOME TAX TREATMENT OF DISSENTERS
 
    Any shareholder of Ventura who effectively dissents from the Merger (see
"Rights of Dissenting Shareholders," above) and who receives cash for his or her
shares will recognize a gain (or loss) for federal income tax purposes equal to
the amount by which the cash received for those shares exceeds (or is less than)
the shareholder's tax basis for the shares. The amount of that gain (or loss),
if any, will be treated as ordinary income (or loss) or long-term or short-term
capital gain (or loss) depending on the length of time the shares are held by
the dissenter, whether the shares are held as a capital asset, and whether the
dissenter is deemed to own shares of Ventura Stock pursuant to the attribution
rules of Section 318 of the Code. In certain circumstances, a dissenter can be
deemed for tax purposes to own shares that are actually owned by a non-dissenter
that is related to the dissenter, with the possible result that the cash
received in the exercise of the dissenter's rights could be treated as a
dividend received pursuant to a corporate distribution rather than an amount
received pursuant to a sale or exchange of Ventura Stock. See "THE MERGER --
Certain Federal Income Tax Consequences."
 
    COMPARISON OF RIGHTS OF HOLDERS OF CITY NATIONAL STOCK AND VENTURA STOCK
 
    City National is incorporated under the laws of the State of Delaware and
Ventura is incorporated under the laws of the State of California. Shareholders
whose rights as shareholders are currently governed by California law and the
Ventura Articles and Ventura Bylaws, will, in the event that such shareholders
receive City National Stock as full or partial consideration in the Merger,
become shareholders of City National, and their rights as such will be governed
by Delaware law and the City National Certificate and City National By-laws.
Certain differences between the rights of holders of shares of City National
Stock and shares of Ventura Stock are summarized below.
 
    The following summary does not purport to be a complete statement of the
rights of shareholders under the applicable California laws and the Ventura
Articles and Ventura Bylaws as compared with the rights of City National
shareholders under the applicable Delaware laws, the City National Certificate
and City National By-laws or a complete description of the specific provisions
referred to herein. The identification of specific differences is not meant to
indicate that other equally or more significant differences do not exist. The
summary is qualified in its entirety by reference to the Delaware Code and the
California Code and the governing corporate instruments of City National and
Ventura, to which such shareholders are referred.
 
CERTAIN VOTING RIGHTS
 
    California law generally requires approval of any reorganization (which
includes a merger, certain exchange reorganizations and certain sale-of-asset
reorganizations) or sale of all or substantially all of the assets of a
corporation by the affirmative vote of the holders of a majority (unless the
articles of
 
                                       77
<PAGE>
incorporation require a higher percentage) of the outstanding shares of each
class of capital stock of the corporation entitled to vote thereon. The Ventura
Articles do not require a higher percentage.
 
    Under Delaware law, any merger, consolidation or sale of all or
substantially all of the assets of a corporation requires the approval of the
holders of a majority (unless the certificate of incorporation requires a higher
percentage) of the outstanding shares of such corporation entitled to vote
thereon. The City National Certificate does not require a higher percentage
except with respect to certain "business combinations" with restricted persons
as more particularly described below.
 
    In general, under California law, no approval of a reorganization is
required by the holders of the outstanding shares in the case of any corporation
if such corporation, or its shareholders immediately before such reorganization,
or both, own, immediately after such reorganization, equity securities (other
than warrants or rights) of the surviving or acquiring corporation, or the
parent of either of the constituent corporations, possessing more than
five-sixths of the voting power of such surviving or acquiring corporation or
such parent.
 
    Delaware law provides that (unless required by the certificate of
incorporation) no authorization by stockholders of a surviving or acquiring
corporation is necessary for a merger if (1) the merger does not amend the
certificate of incorporation of the corporation, (2) each share of stock of the
corporation outstanding prior to the merger remains identical after the merger,
and (3) either no shares of common stock of the surviving corporation and no
shares, securities or obligations convertible into such shares are to be issued
or delivered under the plan of merger or the authorized unissued shares or the
treasury shares of common stock of the corporation to be issued or delivered
under the merger plus shares issuable upon conversion of any other shares,
securities or obligations to be issued or delivered under the merger do not
exceed 20% of the shares of common stock of the corporation outstanding prior to
the merger. The City National Certificate does not require stockholder
authorization for mergers of the type described in the preceding sentence.
 
    Notwithstanding the foregoing, the City National Certificate requires the
approval of the holders of at least 70% of the outstanding shares of City
National Stock for certain "business combinations" between City National or any
subsidiary and a Restricted Person (as hereinafter defined) or its affiliates.
Such business combinations include the sale or other disposition of all,
substantially all, or any substantial part of the assets or business of City
National or its subsidiaries; the purchase or other acquisition of all,
substantially all, or any substantial part of the assets or business of another
person; a merger or consolidation; any reclassification of securities or
recapitalization designed to decrease the holders of any class of City
National's voting securities if, immediately thereafter, a Restricted Person
will be the owner of more than 35% of any such class; and the issuance of voting
securities or rights, warrants or options to acquire any such securities of City
National or a subsidiary to a Restricted Person. The foregoing stockholder
approval is not required for any business combination approved by the Board of
Directors (1) at a time when such other party was not a Restricted Person or (2)
in advance by the affirmative votes of at least the number of directors that is
one less than the entire authorized number of directors of City National, at a
meeting called for such purpose. A "Restricted Person" is any entity or group
which, during any period of 12 consecutive months, directly or indirectly
acquired more than 5% of the shares of any class of voting security of City
National, except if the transaction in which such securities were acquired was
approved in advance by 66 2/3% of the board of directors. A party ceases to be a
Restricted Person at the end of 24 months following the most recent month in
which such securities were acquired which, together with all other securities
acquired in the immediately preceding 11 months, aggregated more than 5% of the
outstanding voting securities.
 
    Under California law, a parent corporation may, without shareholder
approval, merge into itself a subsidiary of which it owns at least 90% of the
outstanding shares of each class of stock.
 
    Similarly, Delaware law permits a merger of a 90% owned subsidiary
corporation into its parent without shareholder approval so long as the
resolution of the Board of Directors of the parent providing
 
                                       78
<PAGE>
for the merger states the terms and conditions of the merger, including the
consideration to be given by the parent in exchange for the subsidiary shares
not owned by the parent.
 
DIVIDENDS
 
    Generally, a California corporation may pay dividends out of retained
earnings or if, after giving effect thereto, (1) the sum of the assets
(excluding goodwill and certain other assets) of the corporation is at least
equal to 1 1/4 times its liabilities (excluding certain deferred credits) and
(2) the current assets of such corporation are at least equal to (A) its current
liabilities or (B) if the average of the earnings of such corporation before
taxes and interest expense for the two preceding fiscal years was less than the
average of the interest expense of such corporation for such fiscal years, 1 1/4
times its current liabilities. In addition, the ability of a California
corporation to pay dividends is restricted by certain limitations for the
benefit of certain preference shares.
 
    Under Delaware law, a corporation may pay dividends out of surplus or, in
the event that no surplus exists, out of its net profits for the fiscal year in
which the dividend is declared or its net profits for the preceding fiscal year,
subject to certain limitations for the benefit of certain preference shares. The
City National Bylaws provide that the Board of Directors may, in accordance with
applicable law, declare dividends.
 
ELECTION OF DIRECTORS; BOARD OF DIRECTORS
 
    Under California law (unless a listed corporation's articles of
incorporation or bylaws provide otherwise), any shareholder of a corporation is
entitled to cumulate his or her votes for the election of directors provided
that at least one shareholder has given notice at the meeting prior to the
voting of such shareholder's intention to cumulate his or her votes. Cumulative
votes may only be cast for candidates who have been nominated before the voting.
The Ventura Bylaws state that provided that Ventura is a "listed corporation"
within the meaning of Section 301.5 of the California Code, Ventura shall not
have cumulative voting. Ventura is a "listed corporation" within the meaning of
Section 301.5 of the California Code and, accordingly, Ventura does not have
cumulative voting.
 
    Delaware law permits cumulative voting in the election of directors of a
corporation if the certificate of incorporation of such corporation provides for
cumulative voting. The City National Certificate does not provide for cumulative
voting.
 
    Under California law, Ventura, as a listed corporation, is permitted to
provide in its articles of incorporation or bylaws for classification of its
Board of Directors into up to three classes. Pursuant to the Ventura Bylaws, the
Ventura Board of Directors consists of three classes of directors. The directors
in each class serve three year terms.
 
    Under Delaware law, City National is permitted to provide in its certificate
of incorporation or in an initial bylaw for classification of its Board of
Directors into up to three classes. The City National Certificate provides that
the City National Board of Directors consists of three classes. The directors in
each class serve on the City National Board of Directors for approximately three
years each. Notwithstanding the foregoing, the directors who currently serve in
class one will serve through the 1997 City National shareholders' meeting, the
directors who currently serve in class two will serve through the 1998 City
National shareholders' meeting and the directors who currently serve in class
three will serve through the 1999 City National shareholders' meeting.
 
REMOVAL OF DIRECTORS; FILLING VACANCIES ON THE BOARD OF DIRECTORS
 
    Under California law the holders of at least 10% of the number of
outstanding shares of any class of stock may initiate a court action to remove
any director for cause. In addition, any or all of the directors of a California
corporation may be removed without cause by the affirmative vote of a majority
of the outstanding shares entitled to vote. However, no director may be removed
(unless the entire board is
 
                                       79
<PAGE>
removed) when the votes cast against removal would be sufficient to elect the
director if voted cumulatively at an election at which the same total number of
votes were cast and the entire number of the directors authorized at the time of
the director's most recent election were then being elected.
 
    Under Delaware law, any or all directors of a corporation may be removed,
with or without cause, by the holders of a majority of the shares entitled to
vote at an election of directors. However, in the case of a corporation whose
board is classified, shareholders may remove directors only for cause, and in
the case of a corporation having cumulative voting, if less than the entire
board is to be removed, no director may be removed without cause if the votes
cast against his removal would be sufficient to elect him if then cumulatively
voted at an election of the entire board of directors, or, if there are classes
of directors, at an election of the class of directors of which he or she is a
part.
 
    Under California law (unless otherwise provided in the articles of
incorporation or bylaws and except for a vacancy created by the removal of a
director), vacancies on the board of directors may be filled by approval of the
board. In addition, any vacancy not filled by the directors may be filled by the
vote of the majority of shares entitled to vote. Neither the Ventura Articles
nor the Ventura Bylaws provide otherwise. Under Delaware law (unless otherwise
provided in the articles of incorporation or bylaws), vacancies and
newly-created directorships resulting from any increase in the authorized number
of directors may be filled by a majority of the directors in office. Neither the
City National Certificate nor the City National Bylaws provides otherwise.
 
SPECIAL MEETINGS OF SHAREHOLDERS; SHAREHOLDER ACTION BY WRITTEN CONSENT
 
    Under California law, a special meeting of shareholders may be called by the
board of directors, the chairman of the board, the president or the holders of
shares entitled to cast not less than 10% of the votes at the meeting or such
additional persons as may be provided in the articles of incorporation or
bylaws. Neither the Ventura Articles nor the Ventura Bylaws permit any other
person to call a special meeting.
 
    Under Delaware law, a special meeting of shareholders may be called by the
board of directors or such other persons as may be authorized by the certificate
of incorporation or by-laws. The City National Bylaws provide that a special
meeting may be called by the president and shall be called by the president or
secretary at the written request of a majority of the board of directors.
 
    Under California law (unless otherwise provided in the articles) and the
Ventura Bylaws, any action which may be taken at a meeting of shareholders may
also be taken by the written consent of the holders of at least the same
proportion of outstanding shares as would be necessary to take such action at a
meeting at which all shares entitled to vote were present and voted, except that
the election of directors by written consent generally requires the unanimous
consent of all shares entitled to vote for the election of directors. The
Ventura Articles do not provide otherwise.
 
    Under Delaware law (unless otherwise provided in the certificate of
incorporation), any action which is required to be taken or may be taken at a
meeting of stockholders, may be taken by a written consent signed by the holders
of outstanding stock having not less than the minimum number of votes that would
be necessary to authorize or take such action at a meeting. The City National
Certificate provides that such action may be taken by the written consent of the
holders of not less than a majority of the stock entitled to vote upon such
action if a meeting were held.
 
AMENDMENT OF BYLAWS
 
    Under California law, bylaws may be adopted, amended or repealed either by
the vote of a majority of the outstanding shares entitled to vote thereon or
(subject to any restrictions in the articles of incorporation or bylaws) by the
approval of the board of directors, except that amendments to the bylaws
specifying or changing a fixed number of directors or the maximum or minimum
number or changing from a fixed to
 
                                       80
<PAGE>
a variable board or vice versa may only be adopted by approval of the
affirmative vote of a majority of the outstanding shares entitled to vote.
 
   
    Under Delaware law, the power to adopt, amend or repeal by-laws is vested in
the stockholders entitled to vote unless the certificate of incorporation
confers the power to adopt, amend or repeal by-laws upon the directors as well.
The City National Certificate provides that the City National Bylaws may be
made, altered, amended or repealed by the Board of Directors.
    
 
AMENDMENT OF CHARTER
 
   
    Under California and Delaware law, amendments to the charter of a
corporation generally require approval by vote of the Board of Directors and the
holders of a majority of outstanding shares entitled to vote thereon and, where
their rights are affected, by the holders of a majority of the outstanding
shares of a class, whether or not such class is entitled to vote thereon by the
provision of the charter.
    
 
DISSENTERS' RIGHTS
 
    Under California law, in the event of a merger of a corporation for which
the approval of outstanding shares is required, dissenting shareholders of such
corporation who follow prescribed statutory procedures are entitled to receive
payment of the fair market value of their shares. For a more complete
description of such rights, see "DISSENTERS' RIGHTS."
 
    Under Delaware law, appraisal rights are generally available for the shares
of any class or series of stock of a corporation in a merger or consolidation;
provided that no appraisal rights are available for the shares of any class or
series of stock which, at the record date for the meeting held to approve such
transaction, were either (1) listed on a national securities exchange or (2)
held of record by more than 2,000 stockholders. Further, no appraisal rights are
available to stockholders of the surviving corporation if their vote is not
required in connection with the merger. Notwithstanding the foregoing provisos,
appraisal rights are available if stockholders receive in the merger or
consolidation consideration other than: (1) shares of stock of the corporation
surviving or resulting from such merger or consolidation; (2) shares of stock of
any other corporation which at the effective date of the merger or consolidation
is either listed on a national securities exchange or held of record by more
than 2,000 stockholders; (3) cash in lieu of fractional shares; or (4) any
combination of the foregoing.
 
CERTAIN BUSINESS COMBINATIONS AND REORGANIZATIONS
 
   
    Generally, Delaware law would prevent an Interested Stockholder (as defined
in the Delaware Code) from engaging in a Business Combination (as defined in
Section 203 of the Delaware Code) with a corporation for three years following
the date such person became an Interested Stockholder unless: (1) before such
person became an Interested Stockholder, the Board of Directors of such
corporation approved either the business combination or the transaction in which
the Interested Stockholder became an Interested Stockholder; (2) upon
consummation of the transaction which resulted in the Interested Stockholder
becoming an Interested Stockholder, the Interested Stockholder owned at least
85% of the voting stock of such corporation outstanding at the time the
transaction commenced (excluding stock held by (A) directors who are also
officers and (B) employee stock ownership plans in which employee participants
do not have the right to determine confidentially whether shares held subject to
the plan will be tendered in a tender or exchange offer), or (3) at or
subsequent to such time, the Business Combination is (x) approved by the Board
of Directors of such corporation and (y) authorized at a meeting of stockholders
by the affirmative vote of the holders of at least 66 2/3% of the outstanding
voting stock of such corporation not owned by the Interested Stockholder.
    
 
    Under California law, if a tender offer or written proposal to acquire a
corporation by a reorganization or certain sales of assets is made to a
corporation's shareholders by an Interested Party (as hereinafter defined) (each
an "Interested Party Proposal"), (1) an affirmative opinion in writing as to the
fairness of
 
                                       81
<PAGE>
   
the consideration to the shareholders of such corporation must be delivered to
shareholders of such corporation (or, in the event that no shareholder approval
is required for the consummation of the transaction, to the corporation's Board
of Directors) and (2) such shareholders must be (a) informed of certain later
tender offers or written proposals for a reorganization or sale of assets made
by other persons and (b) afforded a reasonable opportunity to withdraw any vote,
consent or proxy previously given or shares previously tendered in connection
with the Interested Party Proposal. For the purposes of this paragraph,
"Interested Party" shall mean a person who is a party to the transaction and (x)
directly or indirectly controls the corporation that is the subject of the
tender offer or proposal; (y) is, or is directly or indirectly controlled by, an
officer or director of the subject corporation; or (z) is an entity in which a
material financial interest (as defined in Section 310 of the California Code)
is held by any director or executive officer of the subject corporation.
    
 
    In addition, in connection with any merger transaction, California law
generally requires that, unless all shareholders of a class or series consent
(and except with respect to fractional shares), each share of such class or
series must be treated equally with respect to any distribution of cash,
property, rights or securities. California law also provides generally that if a
corporation that is party to a merger, or its parent, owns more than 50% but
less than 90% of the voting power of the other corporation that is party to such
merger, the nonredeemable shares of common stock of the controlled corporation
may be converted only into nonredeemable shares of the surviving corporation or
a parent party unless all of the shareholders of the class consent.
 
                        VALIDITY OF CITY NATIONAL STOCK
 
   
    Certain legal matters concerning the City National Stock will be passed upon
for City National by Richard H. Sheehan, Jr. Senior Vice President and General
Counsel of City National. As of November 30, 1996, Mr. Sheehan owned
beneficially, directly or indirectly, 2,000 shares of City National Stock and
owned options exercisable for 5,375 shares of such stock.

                                   APPENDIX A
                          AGREEMENT AND PLAN OF MERGER
    
 
    THIS AGREEMENT AND PLAN OF MERGER, dated as of the 15th day of September,
1996 (the "AGREEMENT"), by and between City National Corporation ("CNC"), a
Delaware corporation, and Ventura County National Bancorp, a California
corporation ("VCNB"), is entered into with reference to the following:
 
        A. CNC and VCNB are bank holding companies registered under the Bank
    Holding Company Act of 1956, as amended (the "BHCA") and subject to
    regulation and supervision by the Board of Governors of the Federal Reserve
    System (the "BOARD OF GOVERNORS");
 
        B.  The Boards of Directors of CNC and VCNB have determined that it is
    in the best interests of their respective companies and shareholders to
    consummate the business combination transaction provided for in this
    Agreement;
 
        C.  The parties hereto desire to effect a business combination through a
    merger (the "MERGER"), which will be structured so that VCNB will be merged
    into CNC and that CNC will be the surviving corporation in the Merger;
 
        D. As a condition and inducement to CNC's willingness to enter into this
    Agreement, VCNB and CNC are entering into, immediately after the execution
    and delivery hereof, a Stock Option Agreement (the "STOCK OPTION AGREEMENT")
    dated as of the date hereof, pursuant to which VCNB shall grant to CNC an
    option to purchase shares of the common stock, no par value, of VCNB (the
    "VCNB COMMON STOCK");
 
        E.  The Merger requires certain shareholder and regulatory approvals and
    may be effected only after the necessary approvals have been obtained;
 
        F.  For federal income tax purposes, it is intended that the Merger
    shall qualify as a "reorganization" within the meaning of Section 368 of the
    Internal Revenue Code of 1986, as amended (the "CODE");
 
        G. The parties desire to make certain representations, warranties and
    agreements in connection with the Merger and also to prescribe certain
    conditions to the Merger; and
 
        H. Subject to any specific provisions of this Agreement, it is the
    intent of the parties that CNC by reason of this Agreement shall not (until
    consummation of the Merger) control, and shall not be deemed to control VCNB
    or any of its subsidiaries, directly or indirectly, and shall not exercise
    or be deemed to exercise, directly or indirectly, a controlling influence
    over the management or policies of the VCNB or any of its subsidiaries;
 
NOW, THEREFORE, in consideration of the promises and the mutual agreements
contained herein, the parties hereto agree as follows:
 
                                   ARTICLE I
                      THE MERGER AND RELATED TRANSACTIONS
 
    SECTION 1.1  STRUCTURE OF THE MERGER.  At the effective time of the Merger,

Law ("DGCL") and shall continue its corporate existence under the laws of the
State of Delaware. The name of the Surviving Corporation shall be "City National
Corporation". Upon consummation of the Merger, the separate corporate existence
of VCNB shall cease.
 
                                      A-1
<PAGE>
    SECTION 1.2  CLOSING.  The closing of the Merger (the "CLOSING") will take

occurrence of the Election Deadline (as defined in Section 2.3).
 
    SECTION 1.3  EFFECTIVE TIME.  The Merger shall become effective as set forth

with the Secretary of State of the State of Delaware on the date of Closing. The
term "EFFECTIVE TIME" shall be the date and time when the Merger becomes
effective, as set forth in the Certificate of Merger.
 
    SECTION 1.4  EFFECTS OF THE MERGER.
 
    (a) At the Effective Time, (i) VCNB shall be merged with and into CNC and
the separate existence of VCNB shall cease, (ii) the Certificate of

    (b) At and after the Effective Time, the Merger will have the effects set

    SECTION 1.5  THE BANK MERGER.  After the Merger, and at CNC's discretion,
Ventura County National Bank ("VENTURA BANK") and/or Frontier Bank, N.A.
("FRONTIER") (collectively, the "BANKS") shall be merged with or into City
National Bank ("CNB"), a wholly-owned subsidiary of CNC, pursuant to the Bank
Merger Act and other applicable federal and state laws and regulations (the
"BANK MERGERS").
 
    SECTION 1.6  CALIFORNIA REQUIREMENTS.  CNC and VCNB shall each execute,
deliver and/or certify each and every document, certificate or other instrument
required under the California General Corporation Law (the "CGCL") to be filed
with the Secretary of State of the State of California in order for the
effectiveness of the Merger to be recognized in California. CNC shall file such
items no later than three Business Days following the Effective Time.
 
                                   ARTICLE II
                      EFFECT OF THE MERGER ON THE CAPITAL

to the Effective Time shall remain an issued and outstanding share of common
stock of the Surviving Corporation, and shall not be affected by the Merger;
 
    (b) COMMON STOCK OF VCNB. Each share of common stock, no par value per share
of VCNB ("VCNB Common Stock") issued and outstanding immediately prior to the
Effective Time, shall be converted into the right to receive CNC Common Stock or
cash as provided in Section 2.2(a);
 
    (c) DISSENTING COMMON STOCK. Each share of VCNB Common Stock that is a
"dissenting share" within the meaning of Chapter 13 of the CGCL ("DISSENTING
COMMON STOCK") shall not be converted into or represent a right to receive CNC
Common Stock or cash hereunder unless and until such shares have lost their
status as dissenting shares under Chapter 13 of the CGCL, at which time such
shares shall either be converted into cash or CNC Common Stock pursuant to
Section 2.6.

    (d) CANCELLATION OF CERTAIN SHARES. Any shares of VCNB Common Stock held by
CNC (or any of its wholly owned Subsidiaries) or VCNB (or any of its wholly
owned Subsidiaries), other than those held in a fiduciary capacity or as a
result of debts previously contracted, shall be canceled and retired at the
Effective Time and no consideration shall be issued in exchange therefor.
 
    SECTION 2.2  CONVERSION OF VCNB COMMON STOCK.
 
    (a) Subject to the other provisions of this Article II, each share of VCNB
Common Stock issued and outstanding immediately prior to the Effective Time
(other than Dissenting Common Stock and Common Stock described in Section
2.1(d)) shall, by virtue of the Merger, be converted into the right to receive,
at the election of the holder thereof as provided in Section 2.3, either:
 
        (i) a fraction of a share of CNC Common Stock equal to the quotient
    (such quotient, the "EXCHANGE RATIO") of (i) $5.03, divided by (ii) the
    average of the daily closing prices of a share of CNC Common Stock on the
    New York Stock Exchange as reported in the WALL STREET JOURNAL for the
    twenty consecutive trading days ending on the third trading day immediately
    prior to the Effective Time (such average, the "FINAL CNC STOCK PRICE");
    provided, in the event that the Final CNC Stock Price shall be more than
    $19.10, the Exchange Ratio shall be 0.2634, and in the event that the Final
    CNC Stock Price shall be less than $15.65, the Exchange Ratio shall be
    0.3214; or
 
        (ii) cash in the amount of $5.03 (such amount, the "PER SHARE CASH
    CONSIDERATION"); or
 
       (iii) a combination of CNC Common Stock and cash in the amounts as set
    forth in Subsections 2.2(a)(i) and (a)(ii) above.
 
    (b) At the Effective Time, the stock transfer books of VCNB shall be closed
as to holders of VCNB Common Stock immediately prior to the Effective Time and
no transfer of VCNB Common Stock by any such holder shall thereafter be made or
recognized. If, after the Effective Time, certificates are properly presented in
accordance with Article III of this Agreement to the Exchange Agent (as defined
in Section 2.3), such certificates shall be canceled and exchanged for
certificates representing the number of whole shares of CNC Common Stock, if
any, and/or a check representing the amount of cash, if any, into which the VCNB
Common Stock represented thereby was converted in the Merger, plus any payment
for a fractional share of CNC Common Stock.
 
    SECTION 2.3  ELECTION AND PRORATION PROCEDURES.
 
    (a) ELECTION FORMS AND TYPES OF ELECTIONS. An election form and other
appropriate and customary transmittal materials (which shall specify that
delivery shall be effected, and risk of loss and title to the certificates
theretofore representing shares of Common Stock shall pass, only upon proper
delivery of such certificates to an exchange agent selected by CNC and
reasonably acceptable to VCNB (the "EXCHANGE AGENT")) in such form as CNC and
VCNB shall mutually agree ("ELECTION FORM") shall be mailed no less than
thirty-five days prior to the anticipated Effective Time or on such other date
as VCNB and CNC shall mutually agree ("MAILING DATE") to each holder of record
of VCNB Common Stock as of five Business Days prior to the Mailing Date
("ELECTION FORM RECORD DATE"). CNC shall make available one or more Election
Forms as may be reasonably requested by all persons who become holders (or
beneficial owners) of VCNB Common Stock after the Election Form Record Date and
prior to the Election Deadline (as defined herein), and VCNB shall provide to
the Exchange Agent all information reasonably necessary for it to perform its
obligations as specified herein. Each Election Form shall permit the holder (or
the Beneficial Owner through appropriate and customary documentation and
instructions) to elect (an "ELECTION") to receive either (i) CNC Common Stock (a
"STOCK ELECTION") with respect to all of such holder's VCNB Common Stock, or
(ii) cash (a "CASH ELECTION") with respect to all of such holder's VCNB Common
Stock, or (iii) a specified number of shares of VCNB Common Stock to receive CNC
Common Stock (a "COMBINATION STOCK ELECTION") and a specified number of shares
of VCNB Common Stock to receive cash (a "COMBINATION CASH ELECTION"). Any VCNB
Common Stock (other than Dissenting Common Stock) with respect to which the
holder (or the Beneficial Owner, as the case may be) shall not
 
                                      A-3
<PAGE>
have submitted to the Exchange Agent, an effective, properly completed Election
Form received prior to the Election Deadline shall be deemed to be "UNDESIGNATED
SHARES" hereunder.
 
    (b) PROPER AND TIMELY ELECTION.  Any Election shall have been properly made
and effective only if the Exchange Agent shall have actually received a properly
completed Election Form by 5:00 P.M. on the later of the 30th day following the
Mailing Date or the 31st day following the mailing of any notice required by
1301 of the CGCL (or such other time and date as CNC and VCNB may mutually
agree) (the "ELECTION DEADLINE"). An Election Form shall be deemed properly
completed only if an Election is indicated for each share of VCNB Common Stock
covered by such Election Form and if accompanied by one or more certificates (or
customary affidavits and indemnification regarding the loss or destruction of
such certificates or the guaranteed delivery of such certificates) representing
all shares of VCNB Common Stock covered by such Election Form, together with
duly executed transmittal materials included in or required by the Election
Form. Any Election Form may be revoked or changed by the person submitting such
Election Form at or prior to the Election Deadline. In the event an Election
Form is revoked prior to the Election Deadline, the shares of VCNB Common Stock
represented by such Election Form shall automatically become Undesignated Shares
unless and until a new Election is properly made with respect to such shares on
or before the Election Deadline, and CNC shall cause the certificates
representing such shares of VCNB Common Stock to be promptly returned without
charge to the person submitting the revoked Election Form upon written request
to that effect from the holder who submitted such Election Form. Subject to the
terms of this Agreement and of the Election Form, the Exchange Agent shall have
reasonable discretion to determine whether any election, revocation or change
has been properly or timely made and to disregard immaterial defects in the
Election Forms, and any decisions of CNC and VCNB required by the Exchange Agent
and made in good faith in determining such matters shall be binding and
conclusive. Neither CNC nor the Exchange Agent shall be under any obligation to
notify any person of any defect in an Election Form.
 
    (c) PRORATION.  As promptly as practicable but not later than ten calendar
days after the Effective Time, CNC shall cause the Exchange Agent to effect the
allocation among the holders of VCNB Common Stock of rights to receive CNC
Common Stock or cash in the Merger in accordance with the Election Forms as
follows:
 
        (i) if the aggregate number of shares of VCNB Common Stock as to which
    Stock Elections and Combination Stock Elections shall have effectively been
    made exceeds, and is not approximately equal to, 55% of the issued and
    outstanding shares of VCNB Common Stock as of the Effective Time (the "STOCK
    AMOUNT"), then:
 
           (A) All Undesignated Shares and Dissenting Common Stock shall be
       deemed to have made Cash Elections; and
 
           (B) A stock proration factor (the "STOCK PRORATION FACTOR") shall be
       determined by dividing the Stock Amount by the total number of shares of
       VCNB Common Stock with respect to which effective Stock Elections and
       Combination Stock Elections were made. Each holder of VCNB Common Stock
       who made an effective Stock Election or Combination Stock Election shall
       be entitled to:
 
           (I) the number of shares of CNC Common Stock equal to the product of
               (x) the Exchange Ratio, multiplied by (y) the number of shares of
               VCNB Common Stock covered by such Stock Election or Combination
               Stock Election, multiplied by (z) the Stock Proration Factor; and
 
           (II) cash in an amount equal to the product of (x) the Per Share Cash
               Consideration, multiplied by (y) the number of shares of VCNB
               Common Stock covered by such Stock Election or Combination Stock
               Election, multiplied by (z) one minus the Stock Proration Factor.
 
                                      A-4
<PAGE>
        (ii) if the aggregate number of shares of VCNB Common Stock as to which
    Stock Elections and Combination Stock Elections shall have effectively been
    made shall be less than, and not approximately equal to, the Stock Amount,
    then:
 
           (A) the Exchange Agent shall select by lot such number of holders of
       Undesignated Shares to receive CNC Common Stock as shall be necessary so
       that the number of shares for which a Stock Election and Combination
       Stock Election has been made or is deemed to be made shall be
       approximately equal to the Stock Amount. If all the Undesignated Shares
       plus all shares as to which Stock Elections and Combination Stock
       Elections have been made together are less than, and not approximately
       equal to, the Stock Amount, then:
 
           (B) a cash proration factor (the "CASH PRORATION FACTOR") shall be
       determined by dividing the Stock Amount (less the (i) shares for which an
       effective Stock Election and Combination Stock Election has been made,
       and (ii) all the Undesignated Shares) by the sum of the total number of
       shares of VCNB Common Stock with respect to which effective Cash
       Elections and Combination Cash Elections were made. Each holder of VCNB
       Common Stock who made an effective Cash Election or Combination Cash
       Election shall be entitled to:
 
           (I) cash equal to the product of (x) the Per Share Cash
               Consideration, multiplied by (y) the number of shares of VCNB
               Common Stock covered by such Cash Election or Combination Cash
               Election, multiplied by (z) one minus the Cash Proration Factor;
               and
 
           (II) the number of shares of CNC Common Stock equal to the product of
               (x) the Exchange Ratio, multiplied by (y) the number of shares of
               VCNB Common Stock covered by such Cash Election or Combination
               Cash Election, multiplied by (z) the Cash Proration Factor.
 
    (d) CALCULATIONS.  The calculations required by Section 2.2(a)(i) shall be
prepared by CNC prior to the Effective Time and shall be set forth in a
certificate executed by the Chief Financial Officer of CNC and furnished to VCNB
two Business Days prior to the Effective Time showing the manner of calculation
in reasonable detail. Any calculation of a portion of a share of CNC Common
Stock shall be rounded to the nearest ten-thousandth of a share, and any cash
payment shall be rounded to the nearest cent. For purposes of this Section 2.3,
the shares of VCNB Common Stock for which CNC Common Stock is to be issued as
consideration in the Merger shall be deemed to be "approximately equal" to the
Stock Amount if such number is within 25,000 shares (of VCNB Common Stock) of
the Stock Amount.
 
    (e) NO FRACTIONAL SHARES.  Notwithstanding any other provisions of this
Agreement, each holder of shares of VCNB Common Stock exchanged pursuant to the
Merger who would otherwise have been entitled to receive a fraction of a share
of CNC Common Stock (after taking into account all certificates delivered by
such holder) shall receive, in lieu thereof, cash (without interest) in an
amount equal to such fractional part of a share of CNC Common Stock multiplied
by the Final CNC Stock Price (as defined in Section 2.2). No holder will be
entitled to dividends, voting rights or any other rights as a stockholder in
respect of any fractional share of CNC Common Stock.
 
    SECTION 2.4  STOCK OPTIONS.  Prior to the Effective Time, VCNB shall take
appropriate action such that each option granted pursuant to the 1991 Stock
Option Plan (the "OPTION PLAN") by VCNB to purchase shares of the VCNB Common
Stock that is outstanding and unexercised immediately prior to the Effective
Time shall be cancelled by VCNB in consideration of the payment by VCNB to each
holder of such options of an aggregate amount in cash equal to the positive
difference, if any, between (a) the Per Share Cash Consideration times the
number of shares of VCNB Common Stock as to which such holder has options, and
(b) the aggregate exercise price of such options. At the Effective Time, each
option to purchase a share of Common Stock pursuant to the Option Plan shall
terminate and be of no further force or effect, and any rights thereunder to
purchase shares of VCNB Common Stock or CNC Common Stock shall also terminate
and be of no further force or effect.
 
                                      A-5
<PAGE>
    SECTION 2.5  ADJUSTMENTS FOR DILUTION AND OTHER MATTERS.  If prior to the
Effective Time, (a) VCNB shall declare a stock dividend or distribution on the
VCNB Common Stock, or subdivide, split up, reclassify or combine the VCNB Common
Stock, or declare a dividend, or make a distribution, on the VCNB Common Stock,
in any security convertible into Common Stock (provided that no such action may
be taken by VCNB without CNC's prior written consent as provided in Section 4.2
(b)), or (b) the outstanding shares of CNC Common Stock shall have been
increased, decreased, changed into or exchanged for a different number or kind
of shares or securities, in each case as a result of a reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock
split or other similar change in CNC's capitalization, then an appropriate
adjustment or adjustments will be made to the Exchange Ratio (including the
Final CNC Stock Price and the Final CNC Stock Prices below and above which the
Exchange Ratio is a specified amount pursuant to Section 2.2).
 
    SECTION 2.6  CONVERSION OF DISSENTING COMMON STOCK.
 
    (a) VCNB shall give CNC prompt notice upon receipt by VCNB of any written
demands for appraisal rights, withdrawal of such demands, and any other
documents received or instruments served pursuant to Chapter 13 of the CGCL and
shall give CNC the opportunity to direct all negotiations and proceedings with
respect to such demands. VCNB shall not voluntarily make any payment with
respect to any demands for appraisal rights and shall not, except with the prior
written consent of CNC, settle or offer to settle such demands. Each holder of
Common Stock who becomes entitled, pursuant to provisions of said Chapter 13 of
the CGCL, to payment for his or her shares of Dissenting Common Stock under the
provisions of said Chapter shall receive payment therefor from CNC and such
shares of Common Stock shall be canceled.
 
    (b) If prior to the Election Deadline any shareholder of VCNB shall fail to
perfect, or shall effectively withdraw or lose, his or her rights under Chapter
13 of the CGCL, the Dissenting Common Stock of such holder shall be treated for
purposes of this Article II as any other shares of outstanding Common Stock. If,
after the Election Deadline, any holder of Common Stock shall fail to perfect,
or shall effectively withdraw or lose, his or her right to appraisal of and
payment for his or her Dissenting Common Stock under Chapter 13 of the CGCL,
each share of Dissenting Common Stock of such holder shall be converted into the
right to receive the Per Share Cash Consideration pursuant to this Article II.
 
                                  ARTICLE III
                               EXCHANGE OF SHARES
 
    SECTION 3.1  EXCHANGE PROCEDURES.
 
    (a) EXCHANGE AGENT.  No later than the Effective Time, CNC shall deposit
with the Exchange Agent the number of shares of CNC Common Stock issuable in the
Merger and the amount of cash payable in the Merger. The Exchange Agent shall
not be entitled to vote or exercise any rights of ownership with respect to CNC
Common Stock held by it from time to time hereunder, except that it shall
receive and hold all dividends or other distributions paid or distributed with
respect to such shares for the account of the persons entitled thereto.
 
    (b) EXCHANGE OF CERTIFICATES AND CASH.  After completion of the allocation
procedure set forth in Section 2.3, each holder of a certificate formerly
representing VCNB Common Stock (other than Dissenting Common Stock) who
surrenders or has surrendered such certificate (or customary affidavits and
indemnification regarding the loss or destruction of such certificate), together
with duly executed transmittal materials included in or required by the Election
Form, to the Exchange Agent shall, upon acceptance thereof, be entitled to a
certificate representing CNC Common Stock and/or cash into which the shares of
Common Stock shall have been converted pursuant hereto, as well as cash in lieu
of any fractional shares of CNC Common Stock to which such holder would
otherwise be entitled. The Exchange Agent shall accept such VCNB certificate
upon compliance with such reasonable and customary terms and
 
                                      A-6
<PAGE>
conditions as the Exchange Agent may impose to effect an orderly exchange
thereof in accordance with normal practices. Until surrendered as contemplated
by this Section 3.1, each certificate representing VCNB Common Stock shall be
deemed from and after the Effective Time to evidence only the right to receive
cash and/or CNC Common Stock, as the case may be, upon such surrender. CNC shall
not be obligated to deliver the consideration to which any former holder of
Common Stock is entitled as a result of the Merger until such holder surrenders
his certificate or certificates representing shares of VCNB Common Stock for
exchange as provided in this Article III. If any certificate for shares of CNC
Common Stock, or any check representing cash and/or declared but unpaid
dividends, is to be issued in a name other than that in which a certificate
surrendered for exchange is issued, the certificate so surrendered shall be
properly endorsed and otherwise in proper form for transfer and the person
requesting such exchange shall affix any requisite stock transfer tax stamps to
the certificate surrendered or provide funds for their purchase or establish to
the satisfaction of the Exchange Agent that such taxes are not payable.
 
    (c) AFFILIATES.  Certificates surrendered for exchange by any person
constituting an "affiliate" of VCNB for purposes of Rule 144(a) under the
Securities Act of 1933, as amended (the "SECURITIES ACT"), shall not be
exchanged for certificates representing whole shares of CNC Common Stock until
CNC has received a written agreement from such person as provided in Section
6.17.
 
    SECTION 3.2  VOTING AND DIVIDENDS.  Former shareholders of record of VCNB
shall be entitled to vote after the Effective Time at any meeting of CNC
stockholders the number of whole shares of CNC Common Stock into which their
respective shares of Common Stock are converted, regardless of whether such
holders have exchanged their certificates representing Common Stock for
certificates representing CNC Common Stock in accordance with the provisions of
this Agreement. Until surrendered for exchange in accordance with the provisions
of Section 3.1 of this Agreement, each certificate theretofore representing
shares of Common Stock (other than shares to be canceled pursuant to Section
2.1(d) of this Agreement) shall from and after the Effective Time represent for
all purposes only the right to receive shares of CNC Common Stock, cash in lieu
of fractional shares and/or cash, as set forth in this Agreement. No dividends
or other distributions declared or made after the Effective Time with respect to
CNC Common Stock with a record date after the Effective Time shall be paid to
the holder of any unsurrendered certificate of Common Stock with respect to the
shares of CNC Common Stock represented thereby, until the holder of such
certificate of Common Stock shall surrender such certificate. Subject to the
effect of applicable laws, following surrender of any such certificates of
Common Stock for which shares of CNC Common Stock are to be issued, there shall
be paid to the holder of the certificates, without interest, (i) the amount of
any cash payable with respect to a fractional share of CNC Common Stock to which
such holder is entitled pursuant to Section 2.1(e) and the amount of dividends
or other distributions with a record date after the Effective Time theretofore
paid with respect to such whole shares of CNC Common Stock, and (ii) at the
appropriate payment date, the amount of dividends or other distributions with a
record date after the Effective Time but prior to surrender and a payment date
subsequent to surrender payable with respect to such whole shares of CNC Common
Stock.
 
    SECTION 3.3  NO LIABILITY.  Neither CNC, VCNB nor the Exchange Agent shall
be liable to any holder of shares of Common Stock for any shares of CNC Common
Stock (or dividends or distributions with respect thereto) or cash delivered to
a public official pursuant to any applicable abandoned property, escheat or
similar law.
 
    SECTION 3.4  WITHHOLDING RIGHTS.  CNC or the Exchange Agent shall be
entitled to deduct and withhold from the consideration otherwise payable
pursuant to this Agreement to any holder of shares of Common Stock such amounts
as CNC or the Exchange Agent is required to deduct and withhold with respect to
the making of such payment under the Code, or any provision of state, local or
foreign tax law. To the extent that amounts are so withheld by CNC or the
Exchange Agent, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of the shares of Common Stock in
respect of which such deduction and withholding was made by CNC or the Exchange
Agent.

comply with and perform all material obligations and duties imposed upon it by

VCNB or one or both of the Banks to obtain any necessary approvals, consents or
waivers of any Governmental Authority or other parties required for the Merger
or to perform its covenants or agreements under this Agreement on a timely
basis.
 
    SECTION 4.2  FORBEARANCE BY VCNB AND ITS SUBSIDIARIES.  Except as expressly
provided in this Agreement or as set forth on the Disclosure Schedule, during

Option Plan, issue VCNB Common Stock pursuant to exercise of an option granted
pursuant to the Option Plan, and receive or redeem shares of VCNB Common Stock
pursuant to the exercise of such an option;
 
    (c) sell, transfer, mortgage, encumber or otherwise dispose of any of its
properties or assets with a book value of $250,000 or more, or cancel, release

information, relating to any such inquiry or proposal or otherwise facilitate
any effort or attempt to make or implement a Takeover Proposal, PROVIDED,
HOWEVER, that VCNB may, and may authorize and permit its officers, directors,
employees or agents to, provide third parties with nonpublic information,
otherwise facilitate any effort or attempt by any third party to make or
implement a Takeover Proposal, recommend or endorse any Takeover Proposal with
or by any third party, and participate in discussions and negotiations with any
third party relating to any Takeover Proposal, if its Board of Directors, after
having consulted with and considered the advice of counsel, has reasonably
determined in good faith that the failure to do so would cause the members of
its Board of Directors to breach their fiduciary duties under applicable laws.
VCNB will immediately cease and cause to be terminated any activities,
discussions or negotiations conducted prior to the date of this Agreement with
any parties other than CNC with respect to any of the foregoing. VCNB shall

Takeover Proposal immediately upon the occurrence thereof. As used in this
Agreement, "Takeover Proposal" shall mean, with respect to any person, any
tender or exchange offer, proposal for a merger, consolidation or other business

<PAGE>
the time VCNB or one or both of the Banks shall have requested such consent in
writing, unless during such three-day period CNC shall have promptly requested
further information in writing reasonably necessary to allow the decision to be
made, in which case such consent, unless earlier given or denied, shall be
deemed to have been given two Business Days after the time such reasonably
requested information has been furnished; provided, however, with respect to any
consent requested pursuant to Section 4.2(p), CNC shall give or deny such
request by the end of the business day following the business day on which such
request was made by VCNB.
 
    SECTION 4.4  CONDUCT BY CNC PRIOR TO THE EFFECTIVE TIME.  Except as
expressly provided in this Agreement, during the period from the date of this
Agreement to the Effective Time, CNC shall (a) not take any action which would
reasonably be expected to adversely affect or delay the ability of CNC, VCNB or
one or both of the Banks to obtain any necessary approvals, consents or waivers
of any Governmental Authority required for the transactions contemplated by this
Agreement or to perform its covenants or agreements on a timely basis under this
Agreement, (b) amend its Certificate of Incorporation in any respect that

    (a) RECITALS TRUE.  The information set forth in the recitals of this
Agreement with respect to VCNB and each Bank is true and correct.
 
    (b) CAPITAL STOCK.  VCNB is authorized to issue 20,000,000 shares of Common
Stock, no par value, and is not authorized to issue any other class or series of
capital stock, or any other securities giving the holder thereof the right to

hereof, 9,228,723 shares of Common Stock are issued (of which none were held as
treasury stock and treated as issued but not outstanding), and 636,000 shares
are reserved for issuance under the Option Plan. No shares are reserved for

outstanding shares of capital stock of VCNB are duly authorized, validly issued
and outstanding, fully paid and, nonassessable, and are subject to no preemptive
rights.
 
    (c) AUTHORITY.  Each of VCNB and the Banks has the power and authority, and
is duly qualified in all jurisdictions where such qualification is required
(except for such qualifications the absence of which, individually or in the
aggregate, would not have a Material Adverse Effect on VCNB or either of the
Banks), to carry on its business as it is now being conducted and to own all of
its material properties and assets. VCNB and each of the Banks has all federal,
state, local and foreign governmental authorizations necessary for it to own or
lease its properties and assets and to carry on its business as it is now being
conducted, except for such powers and authorizations the absence of which,
either individually or in the aggregate, would not have a Material Adverse
Effect on the VCNB or either of the Banks.
 
    (d) SUBSIDIARIES.  VCNB has no Subsidiaries, other than the Banks, each of
which is a wholly-owned subsidiary of VCNB. VCNB does not own, directly or
indirectly, any equity portion or voting interest in any corporation,
partnership or other entity, except as received in satisfaction of a debt
previously contracted in good faith.
 
    (e) APPROVALS.  The execution by VCNB of this Agreement has been authorized
by all necessary corporate action, including, but not limited to, a vote by its
board of directors (which approval includes a resolution recommending that this
Agreement and the Merger be approved by the stockholders of VCNB) subject to
adoption of this Agreement by the affirmative vote of the holders of a majority
of the
 
                                      A-11
<PAGE>
outstanding shares of VCNB as required under the CGCL. Subject to shareholder
approval and to receipt of required approvals, consents or waivers of
Governmental Authorities referred to in Section 7.1 (b), this Agreement is a
valid and binding agreement of VCNB, enforceable against it in accordance with
its terms, subject to bankruptcy, insolvency, fraudulent transfer,
reorganization, moratorium and similar laws of general applicability relating to
or affecting creditors' rights, general equitable principles, and the rights of
the FDIC.
 
    (f) NO VIOLATIONS.  The execution, delivery and performance of this
Agreement by VCNB does not, and the consummation of the Merger will not,
constitute (i) a breach or violation of, or a default under any applicable law,
rule or regulation or any material judgment, decree, order, governmental permit
or license, or material indenture, agreement or instrument of VCNB, or to which
it (or any of its respective properties) is subject, which breach, violation or
default would have a Material Adverse Effect on VCNB or would materially hinder
or delay the Merger, or (ii) a breach or violation of, or a default under, its
Articles of Incorporation or Bylaws; and the consummation of the Merger will not
require any approval, consent or waiver under any such law, any rule,
regulation, judgment, decree, order, governmental permit or license or the
approval, consent or waiver of any other party to any such agreement, indenture
or instrument, other than (A) the shareholder approval referred to in Section
7.1(a), (B) the required approvals, consents and waivers of Governmental
Authorities referred to in Section 7.1(b), (C) the approvals, consents or
waivers as are required under the federal and state securities or Blue Sky laws,
(D) any other material approvals or consents or waivers of third parties as set
forth in the Disclosure Schedule, and (E) any other approvals, consents or
waivers the absence of which, individually or in the aggregate, would not result
in a Material Adverse Effect on VCNB or would not materially hinder or delay the
Merger.
 
    (g) COMMUNITY REINVESTMENT ACT.  Each of the Banks received a rating of
"satisfactory" in its most recent examination or interim review with respect to
the Community Reinvestment Act. VCNB has not been advised of any supervisory
concerns regarding any Bank's compliance with the Community Reinvestment Act.
 
   
    (h) REPORTS.  VCNB and each of the Banks have timely filed all material
reports, registrations and statements, together with any amendments required to
be made with respect thereto, that it was required to file since January 1, 1991
with (i) the Board of Governors, (ii) the Office of the Comptroller of the
Currency (the "OCC"), (iii) any state regulatory authority, (iv) the Securities
and Exchange Commission (the "SEC"), (v) the Federal Deposit Insurance
Corporation (the "FDIC") and (vi) any self-regulatory organization (collectively
"GOVERNMENTAL AUTHORITIES") and have paid all fees and assessments due and
payable in connection therewith. Except for normal examinations conducted by a

any proceeding or, to the best knowledge of VCNB, investigation, into the
business or operations of VCNB or either of the Banks since January 1, 1991 and
(ii) neither VCNB nor either of the Banks is a party to any cease and desist
order, written agreement, memorandum of understanding or any similar regulatory
action or order with any Federal or state governmental authorities, nor a
recipient of any extraordinary supervisory letter from, nor has it adopted any
board resolution at the request of, any of its regulators, nor been advised that
any such issuance or request is contemplated. Except as set forth in the
Disclosure Schedule, there is no material unresolved violation, criticism or
exception by any Governmental Authority with respect to any report or statement
relating to any examinations of VCNB by any Governmental Authority with respect
to any report or statement relating to any examinations of VCNB or either of the
Banks. The deposits of Frontier and Ventura Bank are insured by the FDIC in
accordance with the Federal Deposit Insurance Act, up to applicable limits.

    (i) FINANCIAL STATEMENTS.  As of their respective dates, none of VCNB's
Annual Report on Form 10-K for the fiscal year ended December 31, 1995 (the
"1995 10-K") or Quarterly Report on Form 10-Q for the quarters ended March 31,
1996 and June 30, 1996, nor any other document filed subsequent to December 31,
1995 under Section 13(a), 13(d), 14 or 15(d) of the Securities Exchange Act of
1934, as amended (the "EXCHANGE ACT"), each in the form (including exhibits)
filed with the SEC (collectively, the "VCNB REPORTS"), contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary to make the statements made therein, in light of the
circumstances under which they were made, not misleading. Each of the balance
sheets or statements of condition contained or incorporated by reference in the
VCNB Reports (including any related notes and schedules) fairly present the
financial position of the entity or entities to which it relates as of its date
and each of the statements of operations and retained earnings and of cash flows
or equivalent statements contained or incorporated by reference in the VCNB
Reports (including any related notes and schedules) fairly present the results
of operations, retained earnings and cash flows, as the case may be, of the
entity or entities to which it relates for the periods set forth therein
(subject, in the case of unaudited interim statements, to normal year-end audit
adjustments that are not material in amount or effect), in each case in
accordance with the published rules and regulations of the SEC and generally
accepted accounting principles ("GAAP") consistently applied and applicable to
bank holding companies during the periods involved, except as may be noted
therein. The books and records of VCNB and its Subsidiaries have been, and are
being, maintained in all material respects in accordance with GAAP and RAP and
other applicable legal and accounting requirements and reflect only actual
transactions.
    
 
    (j) ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as set forth in the June

the business, assets, financial condition or results of operations of VCNB and
its Subsidiaries that, individually or in the aggregate, have had a Material
Adverse Effect on VCNB and its Subsidiaries; (ii) any amendments to the Articles
of Incorporation or Bylaws of VCNB; (iii) any declarations, setting aside or
payment of any dividend or any other distribution in respect of the capital

timely filed all Tax Returns required to have been filed prior to the Effective
Time (taking into account valid extensions), and all such returns and reports
are correct and complete in all material respects. VCNB has delivered or made
available to CNC true and complete copies of all such Tax Returns for 1992, 1993
and 1994 and, when available, will deliver to CNC true and complete copies of
such Tax Returns for 1995. The Disclosure Schedule sets forth those California

statute of limitations for the assessment of Taxes has not run. All Taxes
(including, but not limited to, any interest, penalty or addition thereto) due,
or required to be withheld and paid over as of the date hereof as shown on such
returns have been paid. To VCNB's knowledge, VCNB has not requested any
extension of time within which to file a return or report that has not since
been timely filed. No deficiency in any Taxes, assessments or governmental
charges have been proposed, asserted or assessed against VCNB that has not been
settled and paid. Except as set forth in the Disclosure Schedule, no waiver of
time to assess any Taxes is in effect and no request for such waiver is pending.
The Disclosure Schedule identifies the amount and expiration dates for all net
operating loss carryforwards and gross timing differences of VCNB as of December
31, 1995. VCNB has not undergone an ownership change within the meaning of
Section 382 of the Code. To VCNB's knowledge, VCNB has no liability for Taxes,
including employment taxes, of any person under Treasury Regulation Section
1.1502-6, as a transferee or successor, or otherwise. Except as set forth in the
Disclosure Schedule, VCNB has not made, nor is it obligated to make, nor is it a
party to any agreement that could reasonably be expected to obligate it to make,

a dealer within the meaning of Code Section 475 and the applicable Treasury
Regulations.

    (l) ABSENCE OF CLAIMS; LITIGATION.  No legal, administrative, arbitration or
other proceedings, claims, actions or governmental or regulatory investigations
of any nature are pending or to its knowledge, threatened against VCNB or either
of the Banks which are reasonably likely, individually or in the aggregate, to
have a Material Adverse Effect on VCNB or to materially hinder or delay
consummation of the Merger. Neither VCNB nor either of the Banks is in default
with respect to any material judgment, order, writ, injunction, decree,
regulatory restriction or award of any court, arbitrator or governmental agency,
authority or instrumentality. The Disclosure Schedule contains a complete
listing of litigation pending or, to VCNB's knowledge, threatened against VCNB

litigation matters in the aggregate.
 
    (m) REGULATORY ACTIONS.  As of the date hereof and to VCNB's actual

violation, criticism, or exception by any governmental authority with respect to
any examinations of VCNB or either of the Banks has been resolved or is in the
process of resolution.
 
    (n) CERTAIN AGREEMENTS.  Neither VCNB nor either of the Banks is a party to
an oral or written (i) consultant agreement, not terminable on 90 days' or less
notice and involving the payment of more than $50,000 per annum, (ii) agreement
with any executive officer or other key employee, the benefits of which are

employment or compensation guarantee extending for a period longer than six
months, or (iv) agreement or plan, any of the benefits of which will be

occurrence of the Merger or the value of any of the benefits of which will be
calculated on the basis of the Merger. CNC has been provided with a complete and
accurate listing of the names and current annual salary rates of all persons

any, holding tax or other powers of attorney for the VCNB and each of its
Subsidiaries.
 
    (o) LABOR MATTERS.  Neither VCNB nor any of its Subsidiaries, is party to,
or is bound by, any collective bargaining agreement, contract, or other
agreement or understanding with a labor organization, nor is any of them the
subject of any proceeding asserting that it has committed an unfair labor
practice or seeking to compel it to bargain with any labor organization as to
wages and conditions of employment, nor is there any strike or labor dispute
involving VCNB or any of its Subsidiaries. VCNB considers its employee relations
and those of each of its Subsidiaries to be satisfactory.
 
    (p) EMPLOYEE BENEFIT PLANS.  A list of all Employee Plans (as hereinafter

<PAGE>
    Except as set forth in the Disclosure Schedule:
 
        (i) the written terms of each of the Employee Plans and, if controlled

    administered in substantial compliance with the applicable requirements of
    the Employee Retirement Income Security Act of 1974, as amended ("ERISA")
    and the Code;

    as to the tax qualification of such Employee Plan, and to the knowledge of
    VCNB such favorable determination has not been modified, revoked or limited
    by failure to satisfy any condition thereof or by a subsequent amendment to,
    or failure to amend, such Employee Plan;
 
        (iii) to VCNB's knowledge, neither VCNB nor any of its Subsidiaries, nor
    any other "disqualified person" or "party in interest" (as defined in Code
    Section 4975 and Section 3(14) of ERISA, respectively) with respect to an
    Employee Plan has engaged in any "prohibited transaction" (as defined in
    Code Section 4975 or Sections 406 or 407 of ERISA) that could reasonably be
    expected to subject VCNB or any of its Subsidiaries to any material tax,
    penalty or liability under Code Section 4975 or Title I of ERISA;
 
        (iv) no Employee Plan is a Multiple Employer Plan within the meaning of
    Code Section 413 or a Multiemployer Plan within the meaning of Section 3(37)
    of ERISA;
 
        (v) neither VCNB nor any of its Subsidiaries has incurred, or has any
    knowledge of, any pending material tax, penalty or liability under Code
    Section 4972 with respect to any Employee Plan;
 
        (vi) continuation health care coverage requirements and notice
    requirements under Code Section 4980B and Sections 601 through 608 of ERISA

    For purposes hereof, the term "Employee Plan" means any "employee benefit
plan" (as defined in Section3(3) of ERISA) as well as any other material written
or formal plan or contract involving direct or indirect compensation under which

and directors and their related interests (all as defined under Federal Reserve
Board Regulation "O"), all of which have been made in compliance with Regulation
O, which listing is true, correct and complete in all material respects. Neither

business, and none of them has received any notice of conflicts with respect

    (s) KNOWLEDGE AS TO CONDITIONS.  VCNB and each of its Subsidiaries knows of

    violation of any applicable Environmental Law. To the knowledge of VCNB,
    none of VCNB or its Subsidiaries has any material liability for remedial
    action with respect to a violation of an Environmental Law, nor has it
    received any written requests for information relating to any material
    violations of any Environmental Law from any governmental authority with
    respect to the condition, use, or operation of any of its properties nor has
    any of them received any notice from any governmental authority or any
    written notice from any other person with respect to any material violation
    of or material liability for any remedial action under any Environmental
    Law.

performed by it to date, and is not in default under, or in breach of, any term
or provision of any material contract, lease, indenture or any other material
agreement to which it is a party, is subject or is otherwise bound and no event

respect to any material claims is being disputed.
 
    (z) LISTING OF LOANS.  Copies, in writing, have been made available to CNC
of the detailed listing of all loans and notes receivable of VCNB and each of
its Subsidiaries as of June 30, 1996, including participations, with the

the date hereof. The term "trusts" as used in this Subsection 5.1(bb) includes
(i) any and all common law or other trusts between an individual, corporation or

    (cc)   CONTINGENT LIABILITIES.  VCNB has no actual knowledge of any facts,
other than those reflected in the financial statements included in the VCNB
Reports or the contracts, litigation and other matters listed in the Disclosure
Schedules, that indicate the existence of a contingent liability of VCNB or any

adverse impact on VCNB.
 
    (dd)   STATEMENTS TRUE AND CORRECT.  None of the information supplied or to

agency or regulatory authority in connection with the transactions contemplated
hereby will, in the case of the Proxy Statement/Prospectus, when it is first

    (ee)   TIMELINESS AND COMPLIANCE OF REPORTS AND FILINGS.  VCNB agrees that
through the Effective Time of the Merger, each of its reports, and other filings
required to be filed with any applicable Governmental Authority will be filed on
a timely basis and will comply in all material respects with all of the
applicable statutes, rules and regulations enforced or promulgated by the
Governmental Authority with which it will be filed and none will contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein, in light of the
circumstances under which they will be made, not misleading. Any financial
statement contained in any such report, or other filing that is intended to
present the financial position of VCNB and/or any of its Subsidiaries will
fairly present the financial position of such entities or entity and will be
prepared in accordance with generally accepted accounting principles or

Notwithstanding anything to the contrary set forth in this Section 5(ee), VCNB
makes no representation or warranty with respect to any information supplied by
CNC or CNB or any of CNC's Reports.

2,211,200 shares are held as treasury stock. All outstanding shares of CNC

<PAGE>
    (c) AUTHORITY.  CNC has the power and authority, and is duly qualified in
all jurisdictions where such qualification is required (except for such
qualifications the absence of which, individually or in the aggregate, would not
have a Material Adverse Effect on CNC), to carry on its business as it is now
being conducted and to own all of its material properties and assets. CNC has
all federal, state, local and foreign governmental authorizations necessary for
it to own or lease its properties and assets and to carry on its business as it
is now being conducted, except for such powers and authorizations the absence of
which, either individually or in the aggregate, would not have a Material
Adverse Effect on CNC.
 
    (d) APPROVALS.  The execution by CNC of this Agreement has been authorized
by all necessary corporate actions of CNC, including, but not limited to, a vote
by its board of directors. No vote, consent or approval of the shareholder of
CNC or the shareholders of CNC is required to authorize this Agreement or the
consummation of the Merger. Subject to receipt of the required approvals,
consents or waivers of Governmental Authorities referred to in Section 7.1(b),
this Agreement is a valid and binding agreement of CNC enforceable against CNC
in accordance with its terms, subject to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and similar laws of general applicability
relating to or affecting creditor's rights, general equity principles, and the
rights of the FDIC.
 
    (e) NO VIOLATIONS.  The execution, delivery and performance of this
Agreement by CNC does not, and consummation of the Merger will not, constitute
(i) a breach or violation of, or a default under, any applicable law, rule or
regulation or any material judgment, decree, order, governmental permit or
license, or material indenture, agreement or instrument of CNC, or to which CNC
(or its property) is subject, which breach, violation or default would have a
Material Adverse Effect on CNC or would materially hinder or delay the Merger or
(ii) a breach or violation of, or a default under, the Certificate of
Incorporation or Bylaws of CNC; and the consummation of the Merger will not
require any approval, consent or waiver under any such law, rule, regulation,
judgment, decree, order, governmental permit or license or the approval, consent
or waiver of any other party to any such agreement, indenture or instrument,
other than (1) the required approvals, consents and waivers of Governmental
Authorities referred to in Section 7.1 (b); and (2) any other approvals,
consents or waivers, the absence of which, individually or in the aggregate,
would not result in a Material Adverse Effect on CNC or would not materially
hinder or delay the Merger.
 
    (f) FINANCIAL STATEMENTS.  As of their respective dates, none of CNC's
Annual Report on Form 10-K for the fiscal year ended December 31, 1995 or
Quarterly Report on Form 10-Q for the quarters ended March 31, 1996 and June 30,
1996, nor any other document filed subsequent to December 31, 1993 under Section
13(a), 13(d), 14 or 15(d) of the Exchange Act, each in the form (including
exhibits) filed with the SEC (collectively, the "CNC REPORTS"), contained or
will contain any untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements
made therein, in light of the circumstances under which they were made, not
misleading. Each of the balance sheets or statements of condition contained or
incorporated by reference in the CNC Reports (including any related notes and
schedules) fairly present the financial position of the entity or entities to
which it relates as of its date and each of the statements of operations and
retained earnings and of cash flows or equivalent statements contained or
incorporated by reference in the CNC Reports (including any related notes and
schedules) fairly present the results of operations, retained earnings and cash
flows, as the case may be, of the entity or entities to which it relates for the
periods set forth therein (subject, in the case of unaudited interim statements,
to normal year-end audit adjustments that are not Material in amount or effect),
in each case in accordance with the published rules and regulations of the SEC
and GAAP consistently applied and applicable to bank holding companies during
the periods involved, except as may be noted therein. The books and records of
CNC have been, and are being maintained in all material respects in accordance
with GAAP and RAP and other applicable legal and accounting requirements and
reflect only actual transactions.
 
    (g) ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as set forth in CNC's
Quarterly Report on Form 10-Q for the quarter ended June 30, 1996, since
December 31, 1995, there have not been any
 
                                      A-20
<PAGE>
changes in the business, assets, financial condition or results of operations of
CNC and its Subsidiaries that, individually or in the aggregate, have had a
Material Adverse Effect on CNC.
 
    (h) ABSENCE OF CLAIMS.  No litigation, proceeding or controversy before any
court or governmental agency or authority is pending against CNC or its
Subsidiaries which is reasonably likely, individually or in the aggregate, to
have a Material Adverse Effect on CNC or to materially hinder or delay
consummation of the Merger, and, to its knowledge, no such litigation,
proceeding, controversy, claim or action has been threatened.
 
    (i) REGULATORY ACTIONS.  Neither CNC nor CNB is a party to any cease and
desist order, written agreement, memorandum of understanding or any similar
regulatory action or order with any Federal or state governmental authorities,
nor a recipient of any extraordinary supervisory letter from, nor has it adopted
any board resolution at the request of any of its regulators, nor been advised
that any such issuance or request is contemplated. As of the date hereof, and to
CNC's actual knowledge, CNC is not the subject of a referral to either the
United States Department of Justice or the Department of Housing and Urban
Development for alleged violations of the Fair Lending Acts. Each material
violation, criticism, or exception by any governmental authority with respect to
any examinations of CNC has been resolved or is in the process of resolution.
 
    (j) KNOWLEDGE AS TO CONDITIONS.  CNC knows of no reason why the approvals,
consents and waivers of Governmental Authorities referred to in Section 7.1(b)
should not be obtained without the imposition of any condition of the type
referred to in the provisos thereto.
 
    (k) COMPLIANCE WITH LAWS.  CNC and its Subsidiaries are not in material
violation in any respect of any material Federal, state or local laws, rules,
regulations or orders applicable to them or by which their properties may be
bound, except such violations as would not have a Material Adverse Effect on
CNC. Without limiting the scope of the previous sentence, neither CNC nor CNB is
in material violation of Regulations B, D, E, Z or DD adopted by the FRB, the
Fair Lending Acts, or those provisions of the United States Code providing
penalties for the laundering of monetary instruments (18 U.S.C. Section1956) or
engaging in monetary transactions in property derived from specified unlawful
activity (18 U.S.C. Section1957).

its most recent examination or interim review with respect to the Community
Reinvestment Act. CNC has not been advised of any supervisory concerns regarding
CNB' compliance with the Community Reinvestment Act.
 
    (n) STATEMENTS TRUE AND CORRECT.  None of the information supplied or to be
supplied by CNC for inclusion in the S-4 (as defined in Section 6.1(a)) or the
Proxy Statement/Prospectus, or incorporated by reference therein, or any other
document to be filed with any governmental agency or regulatory authority in
connection with the transactions contemplated hereby will, in the case of the
Proxy Statement/ Prospectus (or incorporated by reference therein), when it is
first mailed to the shareholders of VCNB, contain any untrue statement of a
material fact or omit to state any material fact necessary in order to make the
statements made therein, in light of the circumstances under which such
statements are made, not misleading or, in the case of the S-4, when it becomes
effective, be false or misleading with respect to any material fact, or omit to

all material respects with all of the applicable statutes, rules and regulations
enforced or promulgated by the Governmental Authority with which it will be
filed and none will contain any untrue statement of a material fact or omit to

statements therein, in light of the circumstances under which they will be made,

Subsidiaries, will be prepared in accordance with generally accepted accounting
principles or applicable banking regulations consistently applied during the
periods involved. Notwithstanding anything to the contrary set forth in this
Section 5.2(o), CNC makes no representation or warranty with respect to any
information supplied by VCNB or VCNB's Subsidiaries (or any of the VCNB
Reports).
 
    (p) TAX REPRESENTATION.  It is the present intention of CNC to continue at
least one significant historic business line of each of VCNB, Ventura Bank and
Frontier, or to use at least a significant portion of each of VCNB's, Ventura
Bank's and Frontier's historic business assets in a business, in each case
within the remaining of Treasury Regulation Section 1.368-1(d).

statement on Form S-4, including the definitive proxy statement and prospectus
(the "Proxy Statement/Prospectus") to be mailed to the VCNB Shareholders to vote
upon the Merger (the "S-4"). CNC shall use all reasonable efforts to have the
S-4 declared effective under the Securities Act as promptly as practicable after
such filing, and VCNB shall thereafter mail the Proxy Statement/Prospectus to
its shareholders. CNC shall also use all reasonable efforts to obtain all
necessary state securities law or "Blue Sky" permits and approvals required to
carry out the transactions contemplated by this Agreement, and obtain the
approval for listing on the New York Stock Exchange of the shares of CNC Common
Stock to be issued to holders of Common Stock in the Merger. VCNB shall furnish
all information concerning VCNB and the holders of VCNB Common Stock as may be
reasonably requested in connection with any such action.
 
    (b) The parties hereto shall cooperate with each other and use reasonable
best efforts to promptly prepare and file all necessary documentation, to effect
all applications, notices, petitions and filings, to obtain as promptly as
practicable all permits, consents, approvals and authorizations of all third
parties and Governmental Authorities which are necessary or advisable to
consummate the transactions contemplated by this Agreement (including, without
limitation, the Merger and Bank Mergers), and to comply with the terms and
conditions of all such permits, consents, approval and authorizations to review
in advance, and to the extent practicable each will consult the other on, in
each case subject to applicable laws relating to the exchange of information,
all the information relating to VCNB or CNC, as the case may be, and any of
their respective Subsidiaries which appear in any filing made with, or written
materials submitted to, any third party or any Governmental Authority in
connection with the transactions contemplated by this Agreement. In exercising
the foregoing right, each of the parties hereto shall act reasonably and as
promptly as practicable. The parties hereto agree that they will consult with
each other with respect to the obtaining of all permits, consents, approvals and

advisable to consummate the transactions contemplated by this Agreement and each
party will keep the other apprised of the status of matters relating to
completion of the transactions contemplated herein.

stockholders and such other matters as may be reasonably necessary or advisable
in connection with the Proxy Statement/Prospectus the S-4 or any other
statement, filing, notice or application made by or on behalf of CNC, VCNB or
any of their respective Subsidiaries to any Governmental Authority in connection
with the transactions contemplated by this Agreement.
 
    (d) CNC and VCNB shall promptly advise each other upon receiving any
communication from any Governmental Authority whose consent or approval is
required for consummation of the transactions contemplated by this Agreement
which causes such party to believe that there is a reasonable likelihood that
the approval of any Governmental Authority required pursuant to Section 7.1(b)
will not be obtained or that the receipt of any such approval will be materially
delayed beyond March 31, 1997.
 
    SECTION 6.2  STOCKHOLDERS' APPROVALS.  VCNB shall duly call, give notice of,
convene and hold a meeting of its shareholders to be held as soon as practicable
following the date hereof for the purpose of obtaining the requisite shareholder
approvals required in connection with this Agreement and the Merger. Subject to
the provisions of the next sentence, VCNB shall, through its Board of Directors,
recommend to its stockholders approval of such matters. VCNB's Board of
Directors may fail to make such recommendation, or withdraw, modify or change
any such recommendation in a manner adverse to CNC if such Board of Directors,
after having consulted with and considered the advice of counsel, has reasonably
determined in good faith that the making of such recommendation, or the failure
to withdraw, modify or change its recommendation, would constitute a breach of
the fiduciary duties of the members of such Board of Directors under applicable
law.
 
    SECTION 6.3  LEGAL CONDITIONS TO MERGER.
 
    (a) Each of CNC and VCNB shall, and shall cause each of its Subsidiaries to,

conditions of any such consent, authorization, order or approval.
 
    (b) Each of CNC and VCNB agrees to use reasonable best efforts to take, or
cause to be taken, all actions, and to do, or cause to be done, all things
necessary, proper or advisable to consummate and make effective, as soon as
practicable after the date of this Agreement, the transactions contemplated

representatives (including, without limitation, directors, officers, and
employees, and their affiliates, and counsel, accountants and other
professionals retained) such reasonable access during normal business hours
throughout the period prior to the Effective Time to the books, records
(including, without limitation, Tax Returns and work papers of independent

<PAGE>
copies of such documents or such information with respect to its businesses and
affairs as CNC may reasonably request and that VCNB and its Subsidiaries may
provide without violation of applicable law or regulation or jeopardy to any
attorney-client or similar privilege to which the Bank may be entitled as
against third parties other than CNC. Without limiting the foregoing, VCNB shall
promptly provide CNC (i) monthly unaudited balance sheets and operating

interview or similar meetings held in connection with any regulatory
examinations of VCNB and its Subsidiaries and, with respect to the examination
findings and results, as VCNB can provide without violation of law. Without
limiting the generality of the foregoing, CNC shall have the right to (i)

CNC shall (i) make its Chief Financial Officer and Controller available to
discuss with VCNB and its representatives CNC's ongoing diligence and review of
VCNB's operations and (ii) shall provide VCNB with written information which is
(a) similar to the written information that VCNB reviewed in connection with
this Agreement, and (b) related to CNC's and its Subsidiaries' business
condition, operations and prospects.
 
    (c) CUSTOMER CALLS. Prior to the Effective Time, representatives of CNC will
be permitted to conduct joint calls upon customers of the Banks, if accompanied
by representatives of the Banks, on a schedule to be agreed upon between the
parties; provided, however, that in the event that either party terminates this
Agreement in accordance with the terms hereof, CNC shall not, for a period of
one (1) year from the date of the termination of this Agreement contact any
customer of the Banks contacted pursuant to this Section 6.4(c).
 
    (d) CONFIDENTIALITY. Neither party shall, and each shall cause its
representatives not to, use any information obtained pursuant to this Section
6.4 for any purpose unrelated to the consummation of the transactions
contemplated by this Agreement. Subject to the requirements of law, each party
shall keep confidential, and shall cause its representatives to keep
confidential, all information, documents and trade secrets obtained pursuant to
this Section 6.4 unless such information (i) becomes or has become available to
such party from other sources not known by such party to be bound by a
confidentiality obligation, (ii) is disclosed with the prior written approval of
the party to which such information pertains or (iii) is or becomes readily
ascertainable from published information or trade sources. In the event that
this Agreement is terminated or the Merger shall otherwise fail to be
consummated, each party shall promptly cause all copies of documents or extracts
thereof containing information and data as to another party hereto to be
returned to the party that furnished the same.
 
    SECTION 6.5  EMPLOYEE BENEFITS.
 
    (a) All employees of VCNB continuing in the employ of CNC shall be entitled
to participate in stock plans, bonus plans and all other benefit plans of CNC on
the same basis as other similarly situated employees of CNC. Each of these
employees will be credited for eligibility, participation, vesting and accrual
purposes (provided that no more than 1,080 hours of sick leave may be carried
over into CNC's sick leave program), with such employee's respective years of
past service with VCNB (or other prior service so credited by VCNB) as though
they had been employees of CNC.
 
    (b) VCNB and each of its Subsidiaries has furnished to CNC its severance
policies applicable to its employees (other than as set forth in the Disclosure
Schedule) and a schedule indicating the amount that would be due as a severance
payment to each such employee if he or she is not offered continued
 
                                      A-24
<PAGE>
employment in an equivalent or substantially similar position by CNC following
the Effective Time. To the extent CNC fails to offer an employee identified on
such schedule continued employment in an equivalent or substantially similar
position following the Effective Time, CNC shall be responsible for paying the
severance payments due such employee as set forth on such schedule.
 
    (c) Provided such agreement is listed on the Disclosure Schedule and a
complete copy of such agreement has been provided to CNC prior to the date
hereof, CNC hereby agrees to honor, in accordance with their terms, any existing
individual employment, severance, deferred compensation and similar agreements
between VCNB or any of its Subsidiaries and any current or former officer,
director, employee or consultant of VCNB or such Subsidiary; provided, however
at the close of business on the last day of the month preceding the Effective
Time, VCNB and its Subsidiaries shall have paid or accrued at least $510,000 for
severance benefits payable to employees of VCNB and its subsidiaries pursuant to
this Section 6.5(c). In the event that payments or accruals made pursuant to
this Section exceed $510,000, such excess shall not be included in determining
Book Value Per Share of VCNB pursuant to Section 7.2(e). Notwithstanding any
other provision of this Agreement, no employee shall receive duplicative
benefits by reason of this Section.
 
    (d) VCNB shall pay or accrue, up to $100,000 in retention bonuses or other
similar incentives for employees of VCNB or one of the Banks, the selection of
such employees and the amounts of such payments to be mutually acceptable to the
parties. In the event that payments or accruals are made pursuant to this
Section, such amount shall not be included in determining Book Value Per Share
of VCNB pursuant to Section 7.2(e).
 
    SECTION 6.6  CERTAIN FILINGS, CONSENTS AND ARRANGEMENTS.  CNC, VCNB and each
of their respective Subsidiaries shall (a) promptly make any filings and
applications required to be filed in order to obtain all approvals, consents and
waivers of the Board of Governors, the OCC, the FDIC and any other Governmental
Authorities or government entities necessary or appropriate for the consummation
of the transactions contemplated hereby, (b) cooperate with one another (i) in
promptly determining what filings are required to be made or approvals, consents
or waivers are required to be obtained under any relevant Federal, state or
foreign law or regulation, (ii) in providing the other a reasonable opportunity
to review and comment upon the publicly available portions of such filings, and
(iii) in promptly making any such filings, furnishing information required in
connection therewith and seeking timely to obtain any such approvals, consents
or waivers and (c) deliver to the other copies of publicly available portions of
all such filings and applications promptly after they are filed.
 
    SECTION 6.7  ADDITIONAL AGREEMENTS; PARTIES.  Subject to the terms and
conditions herein provided, each of the parties hereto agrees to use all
commercially reasonable efforts to take promptly, or cause to be taken promptly,
all actions and to do promptly or cause to be done promptly, all things
necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by this Agreement as
promptly as practicable, including using commercially reasonable efforts to
obtain all necessary actions or nonactions, extensions, waivers, consents and
approvals from all applicable Governmental Authorities, affecting all necessary
registrations, applications and filings and obtaining any required contractual
consents (including consent to assignment of leases where required) and
regulatory approvals.
 
    SECTION 6.8  PUBLICITY.  The initial press release announcing this Agreement
shall be a joint press release and thereafter CNC and VCNB shall consult with
each other in issuing any press releases or otherwise making public statements
with respect to the transactions contemplated hereby and in making any filings
with any governmental authority or with any national securities exchange with
respect thereto. If any party hereto, on the advice of counsel, determines that
a disclosure is required by law, it may make such disclosure without the consent
of the other parties, but only after affording the other parties a reasonable
opportunity to review and comment upon the disclosure.
 
                                      A-25
<PAGE>
    SECTION 6.9  NOTIFICATION OF CERTAIN MATTERS.  VCNB shall give CNC, and CNC
shall give VCNB, prompt notice of: (a) any material change in its business,
operations, or prospects, (b) any complaints, investigations or hearings (or
communications indicating that same may be contemplated) of any governmental
agency or Governmental Authority, (c) the institution or the threat of material
litigation, or (d) any event or condition that constitutes a breach of this
Agreement, or that might be reasonably expected to cause its representations or
warranties set forth herein not to be true and correct in all material respects
as of the Effective Time.
 
    SECTION 6.10  PRE-CLOSING ADJUSTMENTS.  At or before the Closing, VCNB shall
make, and shall cause its Subsidiaries to make, and the Subsidiaries shall make,
such accounting entries or adjustments, including charge-offs of loans, as CNC
shall direct in order to implement its plans for the Subsidiaries following the
Closing or to reflect expenses and costs related to the Bank Merger; PROVIDED,
HOWEVER, that (a) VCNB and its Subsidiaries shall not be required to take such
actions more than one day prior to the Effective Time or prior to the time CNC
agrees in writing that all of the conditions to its obligation to close as set
forth in Section 7.2 have been satisfied or waived, and (b) based upon
consultation with counsel and accountants for VCNB and its Subsidiaries, no such
adjustment shall (i) require any filing with any governmental agency or
authority, (ii) violate any law, rule or regulation applicable to VCNB or its
Subsidiaries, or (iii) otherwise materially disadvantage VCNB or its
Subsidiaries if the Acquisition were not consummated; PROVIDED that in any
event, no accrual or reserve made by VCNB or its Subsidiaries pursuant to this
Section 6.10, or any litigation or regulatory proceeding arising out of any such
accrual or reserve, shall constitute or be deemed to be a breach, violation of
or failure to satisfy any representation, warranty, covenant, condition or other
provision of this Agreement or otherwise be considered in determining whether
any such breach, violation or failure to satisfy shall have occurred. The
recording of such adjustments shall not be deemed to imply any misstatement of
previously furnished financial statements or information, shall not be construed
as concurrence of VCNB's or its Subsidiaries' management with any such
adjustments, and shall not affect the Exchange Ratio or the Per Share Cash
Consideration.
 
    SECTION 6.11  DIRECTOR RESIGNATIONS.  VCNB and its Subsidiaries shall use
reasonable efforts to cause to be delivered to CNC at the Closing, the
resignations of the members of the Board of Directors of VCNB and its
Subsidiaries.
 
    SECTION 6.12  HUMAN RESOURCES ISSUES.  VCNB and each of its Subsidiaries
agree to cooperate with CNC with respect to any formal meetings or interviews
with one or more employees called or arranged by it and held for the purpose of
discussing the transactions contemplated by this Agreement or their effect on
such employees, with CNC given the opportunity to participate in such meetings
or interviews. This section is not intended to apply to casual conversations
about the transaction or informal meetings initiated by employees, or to
prohibit discussion in general, but rather to allow CNC a role in the formal
presentation of the transaction to employees, and an opportunity to participate
in the significant, formal meetings at which the transaction is explained and
discussed.
 
    SECTION 6.13  ASSISTANCE WITH THIRD-PARTY AGREEMENTS.
 
    (a) VCNB and its Subsidiaries shall cooperate with and use all reasonable
efforts to assist CNC in (a) gaining access to all of their third-party vendors,
landlords of all of their leased properties and other parties to material
agreements, promptly after the date of this Agreement, (b) obtaining the
cooperation of such third parties in a smooth transition in accordance with
CNC's timetable at or after the Effective Time.
 
    (b) Without limiting Section 6.13(a), VCNB and its Subsidiaries shall use
all reasonable efforts to provide data processing and other processing support,
including support from outside contractors, to assist CNC in performing all
tasks reasonably required to result in a successful conversion of their data and
other files and records to CNC's production environment, when requested by CNC
and sufficient to ensure that a successful conversion can occur at such time as
CNC requests at or after the Effective Time. Among other things, VCNB and its
Subsidiaries shall:
 
                                      A-26
<PAGE>
        (i) cooperate with CNC to establish a mutually agreeable project plan to
    effectuate the conversion;
 
        (ii) use their commercially reasonable efforts to have VCNB's and its
    Subsidiaries' outside contractors continue to support both the conversion
    effort and its needs until the conversion can be established;
 
        (iii) provide, or use its commercially reasonable efforts to obtain from
    any outside contractors, all data or other files and layouts requested by
    CNC for use in planning the conversion, as soon as possible;
 
        (iv) provide reasonable access to personnel at corporate headquarters,
    data and other processing centers, all branches and, with the consent of
    outside contractors, at outside contractors, to enable the conversion effort
    to be completed on schedule; and
 
        (v) to the extent reasonably practicable, give notice of termination,
    conditioned upon the completion of the transactions contemplated hereby, of
    the contracts of outside data and other processing contractors or other
    third-party vendors when directed to do so by CNC.
 
    Notwithstanding the foregoing, neither VCNB nor the Banks shall be required
to give any notice of termination required by this Section 6.13 (x) more than
thirty days prior to the Effective Time and (y) unless CNC states in writing
that, to the best of its knowledge, all conditions to Closing set forth in
Article VII have been or will be satisfied or waived; provided, however, that
VCNB and the Banks shall take action as directed by CNC at any time (1) to
terminate any contract other than that described in clause (2) hereof, if CNC
indemnifies VCNB and the Banks for the incremental costs of obtaining a
replacement contract in the event that the Merger is not consummated other than
due to breaches of this Agreement by VCNB; and (2) to terminate any of the
Bank's outside data processing contracts (the "DP CONTRACTS") if (A) CNC
provides an undertaking to VCNB and the Banks in form and substance reasonably
satisfactory to VCNB and the Banks to the effect that CNC shall, in the event
that the Merger is not consummated, indemnify VCNB and the Banks against all
losses, claims, damages or liabilities resulting from such action, and (B) CNC
agrees to compensate VCNB or the Banks for arrangements through a third-party
provider reasonably acceptable to VCNB providing service levels reasonably
comparable to those provided under the DP Contracts under terms no more
burdensome and at a price no higher to VCNB and the Banks than is provided in
the DP Contracts for their respective needs in the event such contracts are
terminated and the Merger is not consummated, other than as a result of a
failure to consummate the Merger due to breaches of this Agreement by VCNB and
further provided, that CNC's obligations under the foregoing proviso are limited
to payments for one year in an aggregate amount not greater than 150% of that
paid by VCNB or the Banks pursuant to the DP Contracts for the last twelve
months for which such DP Contracts were in effect.
 
    (c) CNC agrees that all actions taken pursuant to this Section 6.13 shall be
taken in a manner intended to minimize disruption to the customary business
activities of VCNB and its Subsidiaries.
 
    SECTION 6.14  NOTICES AND COMMUNICATIONS.  VCNB and its Subsidiaries shall,

(12 U.S.C 2101, et seq.), with respect to all employees of VCNB and its
Subsidiaries covered by such act who are to be terminated by CNC within sixty
days following the effective time, including the issuance of notices to such
employees.
 
    SECTION 6.15  INSURANCE POLICIES ASSIGNMENT.  VCNB and its Subsidiaries
agree to make commercially reasonable efforts to obtain consent to partial or
complete assignments of any of their insurance
 
                                      A-27
<PAGE>
policies if requested to do so by CNC, to the extent necessary to maintain the
benefits to CNC of such policies as they apply to VCNB and its Subsidiaries.

of any material unfiled insurance claims of which they have knowledge and for
which they believe coverage exists.
 
    SECTION 6.16  ADDITIONAL AGREEMENTS; OFFICERS AND DIRECTORS.  In case at any
time after the Effective Time any further action is necessary or desirable to
carry out the purposes of this Agreement or to vest CNB with full title to all
properties, assets, rights, approvals, immunities and franchises of either CNC
or VCNB, the proper officers and directors of each party to this Agreement shall
take all necessary or appropriate action.
 
    SECTION 6.17  AFFILIATES AND FIVE PERCENT SHAREHOLDERS.
 
    (a) At least 40 days prior to the Effective Time, VCNB shall deliver to CNC
a letter identifying all persons who are, at the time this Agreement is
submitted for approval to the stockholders of VCNB, "affiliates" of VCNB for
purposes of Rule 145 under the Securities Act. VCNB shall use commercially
reasonable efforts to cause each such affiliate to deliver to CNC prior to the
Effective Time a written "Affiliates" agreement, in customary form, providing
that such person shall dispose of the CNC Common Stock to be received by such
person in the Merger only in accordance with applicable law.
 
    (b) Prior to the Effective Time, VCNB shall use commercially reasonable
efforts to cause each person or group of persons who holds more than five
percent (5%) of VCNB's Common Stock (regardless of whether such person is an
"affiliate") to deliver to the law firm delivering the opinion pursuant to
Section 7.3(d) a letter stating that such stockholder(s) have no present
intention to dispose of the CNC Common Stock he or she or they will receive in
the Merger, and committing that he, she or they will not dispose of such CNC
Common Stock in such a manner as to cause a violation of the "continuity of
shareholder interest" requirements of Treasury Regulation 1.368-1.
 
    SECTION 6.18  COOPERATION.  VCNB shall and shall cause the Banks to
cooperate with CNC and CNB in all reasonable respects in accomplishing the Bank

directors, officers, employees and agents of VCNB and its Subsidiaries as
provided in their respective articles of incorporation, bylaws, indemnification
agreements or otherwise in effect as of the date hereof with respect to matters
occurring prior to the Effective Time, shall survive the Merger and Bank Mergers
and shall continue in full force and effect. CNC further agrees that, following
consummation of the Merger and Bank Mergers: to the greatest extent permitted by
Delaware law, and the organizational documents or bylaws of CNC as in effect of
the date hereof, it shall indemnify, defend and hold harmless individuals who
were officers and directors of VCNB and its Subsidiaries as of the date hereof
or immediately prior to the Effective Time for any claim or loss arising out of
their actions while a director or officer, including any acts relating to this
Agreement, and shall pay the expenses, including attorneys' fees, of such
individual in advance of the final resolution of any claim, provided such
individuals shall first execute an undertaking acceptable to the Bank to return
such advances in the event it has finally concluded such indemnification is not
allowed under applicable law.

Stock in favor of the Merger at the shareholders' meeting held for that purpose,
granting a proxy for such shares to CNC, and to certain representations
concerning the ownership of VCNB Common Stock and the CNC Common Stock to be
received in the Merger, within five (5) days after the date of this Agreement.

                       CALIFORNIA GENERAL CORPORATION LAW
                         DISSENTERS' RIGHTS--CHAPTER 13
 
SECTION 1300.    RIGHT TO REQUIRE PURCHASE--"DISSENTING SHARES" AND "DISSENTING
                 SHAREHOLDER" DEFINED.
 
    (a) If the approval of the outstanding shares (Section 152) of a corporation
is required for a reorganization under subdivisions (a) and (b) or subdivision
(e) or (f) of Section 1201, each shareholder of the corporation entitled to vote
on the transaction and each shareholder of a subsidiary corporation in a
short-form merger may, by complying with this chapter, require the corporation
in which the shareholder holds shares to purchase for cash at their fair market
value the shares owned by the shareholder which are dissenting shares as defined
in subdivision (b). The fair market value shall be determined as of the day
before the first announcement of the terms of the proposed reorganization or
short-form merger, excluding any appreciation or depreciation in consequence of
the proposed action, but adjusted for any stock split, reverse stock split, or
share dividend which becomes effective thereafter.
 
    (b) As used in this chapter, "dissenting shares" means shares which come
within all of the following descriptions:
 
(1) Which were not immediately prior to the reorganization or short-form merger
    either (A) listed on any national securities exchange certified by the
    Commissioner of Corporations under subdivision (o) of Section 25100 or (B)
    listed on the list of OTC margin stocks issued by the Board of Governors of
    the Federal Reserve System, and the notice of meeting of shareholders to act
    upon the reorganization summarizes this section and Sections 1301, 1302,
    1303 and 1304; provided, however, that this provision does not apply to any
    shares with respect to which there exists any restriction on transfer
    imposed by the corporation or by any law or regulation; and provided,
    further, that this provision does not apply to any class of shares described
    in subparagraph (A) or (B) if demands for payment are filed with respect to
    5 percent or more of the outstanding shares of that class.
 
(2) Which were outstanding on the date for the determination of shareholders
    entitled to vote on the reorganization and (A) were not voted in favor of
    the reorganization or, (B) if described in subparagraph (A) or (B) of
    paragraph (1) (without regard to the provisos in that paragraph), were voted
    against the reorganization, or which were held of record on the effective
    date of a short-form merger; provided, however, that subparagraph (A) rather
    than subparagraph (B) of this paragraph applies in any case where the
    approval required by Section 201 is sought by written consent rather than a
    meeting.
 
(3) Which the dissenting shareholder has demanded that the corporation purchase
    at their fair market value, in accordance with Section 301.
 
(4) Which the dissenting shareholder has submitted the endorsement, in
    accordance with Section 1302.
 
(c) As used in this chapter, "dissenting shareholder" means the recordholder of
    dissenting shares and includes a transferee of record.
 
SECTION 1301.    DEMAND FOR PURCHASE
 
    (a) If, in the case of a reorganization, any shareholders of a corporation
have a right under Section 1300, subject to compliance with paragraphs (3) and
(4) of subdivision (b) thereof, to require the corporation to purchase their
shares for cash, such corporation shall mail to each such shareholder a notice
of the approval of the reorganization by its outstanding shares (Section 152)
within 10 days after the date of such approval, accompanied by a copy of
Sections 1300, 1302, 1303, 1304 and this section, a statement of the price
determined by the corporation to represent the fair market value of the
dissenting shares, and a
 
                                      B-1
<PAGE>
brief description of the procedure to be followed if the shareholder desires to
exercise the shareholder's rights under such sections. The statement of price
constitutes an offer by the corporation to purchase at the price stated any
dissenting shares as defined in subsection (b) of Section 1300, unless they lose
their status as dissenting shares under Section 1309.
 
    (b) Any shareholder who has a right to require the corporation to purchase
the shareholder's shares for cash under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon
the reorganization, or (2) in any other case within 30 days after the date on
which the notice of the approval by the outstanding shares pursuant to
subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder.
 
    (c) The demand shall state the number and class of the shares held of record
by the shareholder which the shareholder demands that the corporation purchase
and shall contain a statement of what such shareholder claims to be the fair
market value of those shares as of the day before the announcement of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.
 
SECTION 1302.    ENDORSEMENT OF SHARES
 
    Within 30 days after the date on which notice of the approval by the
outstanding shares or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder, the shareholder shall submit to the corporation at
its principal office or at the office of any transfer agent thereof, (a) if the
shares are certificated securities, the shareholder's certificates representing
any shares which the shareholder demands that the corporation purchase, to be
stamped or endorsed with a statement that the shares are dissenting shares or to
be exchanged for certificates of appropriate denomination so stamped or endorsed
or (b) if the shares are uncertificated securities, written notice of the number
of shares which the shareholder demands that the corporation purchase. Upon
subsequent transfers of the dissenting shares on the books of the corporation,
the new certificates, initial transaction statement, and other written
statements issued therefor shall bear a like statement, together with the name
of the original dissenting holder of the shares.
 
SECTION 1303.    AGREED PRICE--TIME FOR PAYMENT
 
    (a) If the corporation and the shareholder agree that the shares are
dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the fair
market value of any dissenting shares as between the corporation and the holders
thereof shall be filed with he secretary of the corporation.
 
    (b) Subject to the provisions of Section 1306, payment of the fair market
value of dissenting shares shall be made within 30 days after the amount thereof
has been agreed or within 30 days after the amount thereof has been agreed or
within 30 days after any statutory or contractual conditions to the
reorganization are satisfied, whichever is later, and in the case of
certificated securities, subject to surrender of the certificates therefor,
unless provided otherwise by agreement.
 
SECTION 1304.    DISSENTERS' ACTION TO ENFORCE PAYMENT
 
    (a) If the corporation denies that the shares are dissenting shares, or the
corporation and the shareholder fail to agree upon the fair market value of the
shares, then the shareholder demanding
 
                                      B-2
<PAGE>
purchase of such shares as dissenting shares or any interested corporation,
within six months after the date on which notice of the approval by the
outstanding shares (Section 152) or notice pursuant to subdivision (i) of
Section 1110 was mailed to the shareholder, but not thereafter, may file a
complaint in the superior court of the proper county praying the court to
determine whether the shares are dissenting shares or the fair market value of
the dissenting shares or both or may intervene in any action pending on such a
complaint.
 
    (b) Two or more dissenting shareholders may join as plaintiffs or be joined
as defendants in any such action and two or more such actions may be
consolidated.
 
    (c) On the trial of the action, the court shall determine the issues. If the
status of the shares as dissenting shares is in issue, the court shall first
determine that issue. If the fair market value of the dissenting shares is in
issue, the court shall determined, or shall appoint one or more impartial
appraisers to determine, the fair market value of the shares.
 
SECTION 1305.    APPRAISERS' REPORT--PAYMENT--COSTS
 
    (a) If the court appoints an appraiser or appraisers, they shall proceed
forthwith to determine the fair market value per share. Within the time fixed by
the court, the appraisers, or a majority of them, shall make and file a report
in the office of the clerk of the court. Thereupon, on the motion of any party,
the report shall be submitted to the court and considered on such evidence as
the court considers relevant. If the court finds the report reasonable, the
court may confirm it.
 
    (b) If a majority of the appraisers appointed fail to make and file a report
within 10 days from the date of their appointment or within such further time as
may be allowed by the court or the report is not confirmed by the court, the
court shall determine the fair market value of the dissenting shares.
 
    (c) Subject to the provisions of Section 1306, judgment shall be rendered
against the corporation for payment of an amount equal to the fair market value
of each dissenting share multiplied by the number of dissenting shares which any
dissenting shareholder who is a party, or who has intervened, is entitled to
require the corporation to purchase, with interest thereon at the legal rate
from the date on which judgment was entered.
 
    (d) Any such judgment shall be payable forthwith with respect to
uncertificated securities and, with respect to certificated securities, only
upon the endorsement and delivery to the corporation of the certificates for the
shares described in the judgment. Any party may appeal from the judgment.
 
    (e) The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interest
at the legal rate on judgments from the date of compliance with Sections 1300,
1301 and 1302 if the value awarded by the court for the shares is more than 125
percent of the price offered by the corporation under subdivision (a) of Section
1301).
 
SECTION 1306.    DISSENTING SHAREHOLDER'S STATUS AS CREDITOR
 
    To the extent that the provisions of Chapter 5 prevent the payment to any
holders of dissenting shares of their fair market value, they shall become
creditors of the corporation for the amount thereof together with interest at
the legal rate on judgments until the date of payment, but subordinate to all
other creditors in any liquidation proceeding, such debt to be payable when
permissible under the provisions of Chapter 5.
 
SECTION 1307.    DIVIDENDS PAID AS CREDIT AGAINST PAYMENT.
 
    Cash dividends declared and paid by the corporation upon the dissenting
shares after the date of approval of the reorganization by the outstanding
shares (Section 152) and prior to payment for the shares by the corporation
shall be credited against he total amount to be paid by the corporation
therefor.

<PAGE>
SECTION 1308.    CONTINUING RIGHTS AND PRIVILEGES OF DISSENTING SHAREHOLDERS.
 
    Except as expressly limited in this chapter, holders of dissenting shares
continue to have all the rights and privileges incident to their shares, until
the fair market value of their shares is agreed upon or determined. A dissenting
shareholder may not withdraw a demand for payment unless the corporation
consents thereto.
 
SECTION 1309.    TERMINATION OF DISSENTING SHAREHOLDER STATUS.
 
    Dissenting shares lose their status as dissenting shares and the holders
thereof cease to be dissenting shareholders and cease to be entitled to require
the corporation to purchase their shares upon the happening of any of the
following:
 
    (a) The corporation abandons the reorganization. Upon abandonment of the
reorganization, the corporation shall pay on demand to any dissenting
shareholder who has initiated proceedings in good faith under this chapter all
necessary expenses incurred in such proceedings and reasonable attorneys' fees.
 
    (b) The shares are transferred prior to their submission for endorsement in
accordance with Section 1302 or are surrendered for conversion into shares of
another class in accordance with the articles.
 
    (c) The dissenting shareholder and the corporation do not agree upon the
status of the shares as dissenting shares or upon the purchase price of the
shares, and neither files a complaint or intervenes in a pending action as
provided in Section 1304, within six months after the date on which notice of
the approval by the outstanding shares or notice pursuant to subdivision (i) of
Section 1110 was mailed to the shareholder.
 
    (d) The dissenting shareholder, with the consent of the corporation,
withdraws the shareholder's demand for purchase of the dissenting shares.
 
SECTION 1310.    SUSPENSION OF PROCEEDINGS FOR PAYMENT OF PENDING LITIGATION.
 
    If litigation is instituted to test the sufficiency or regularity of the
votes of the shareholders in authorizing a reorganization, any proceedings under
Section 1304 and 1305 shall be suspended until final determination of such
litigation.
 
SECTION 1311.    EXEMPT SHARES.
 
    This chapter, except Section 1312, does not apply to classes of shares whose
terms and provisions specifically set forth the amount to be paid in respect to
such shares in the event of a reorganization or merger.
 
SECTION 1312.    ATTACKING VALIDITY OF REORGANIZATION OR MERGER.
 
    (a) No shareholder of a corporation who has a right under this chapter to
demand payment of cash for the shares held by the shareholder shall have any
right at law or in equity to attack the validity of the reorganization or
short-form merger, or to have the reorganization or short-form merger set aside
or rescinded, except in an action to test whether the number of shares required
to authorize or approve the reorganization have been legally voted in favor
thereof; but any holder of shares of a class whose terms and provisions
specifically set forth the amount to be paid in respect to them in the event of
a reorganization or short-form merger is entitled to payment in accordance with
those terms and provisions or, if the principal terms of the reorganization are
approved pursuant to subdivision (b) of Section 1202, is entitled to payment in
accordance with the terms and provisions of the approved reorganization.
 
                                      B-4
<PAGE>
    (b) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash for
such shareholder's shares pursuant to this chapter; but if the shareholder
institutes any action to attack the validity of the reorganization or short-form
merger or to have the reorganization or short-form merger set aside or
rescinded, the shareholder shall not thereafter have any right to demand payment
of cash for the shareholder's shares pursuant to this chapter. The court in any
action attacking the validity of the reorganization or short-form merger or to
have the reorganization or short-form merger set aside or rescinded shall not
restrain or enjoin the consummation of transaction except upon 10 days' prior
notice to the corporation and upon a determination by the court that clearly no
other remedy will adequately protect the complaining shareholder or the class of
shareholders of which such shareholder is a member.
 
    (c) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, in any action to attack the
validity of the reorganization or short-form merger or to have the
reorganization or short-form merger set aside or rescinded, (1) a party to a
reorganization or short-form merger which controls another party to the
reorganization or short-form merger shall have the burden of proving that the
transaction is just and reasonable as to the shareholders of the controlled
party, and (2) a person who controls two or more parties to a reorganization
shall have the burden of proving that the transaction is just and reasonable as
to the shareholders of any party so controlled.

    Re: Certain Federal Income Tax Consequence of the Merger of Ventura County
       National Bancorp with and into City National Corporation
 
    Ladies and Gentlemen:
 
    In accordance with your request, we provide the following analysis and
opinions relating to certain federal income tax consequences of the transaction
(the "Merger") whereby Ventura County National Bancorp ("Ventura") will merge
with and into City National Corporation ("City National") pursuant to that
certain Agreement and Plan of Merger dated as of September 15, 1996 (the
"Agreement"). Terms used herein have the same meaning as in the Agreement.
 
    In the Merger, Ventura shall be merged with and into City National by a
statutory merger in accordance with the Delaware General Corporation Law and the
California General Corporation Law. The separate existence of Ventura shall
cease and City National shall be the surviving entity. City National shall
succeed, without other transfer, to all the rights and property of Ventura and
shall be subject to all the debts and liabilities of Ventura in the same manner
as if City National had itself incurred them.
 
    Subject to the provisions of the Agreement, each share of Ventura Stock
which shall be outstanding immediately prior to the Merger shall automatically
be converted to shares of City National Stock, cash, or a mixture of City
National Stock and cash pursuant to certain shareholder elections permitted
under the Agreement. Each share of Ventura Stock which shall be outstanding
immediately prior to the Merger (other than shares which are dissenting shares
within the meaning of the California General Corporation Law) shall, without any
action on the part of the holder thereof, cease to be outstanding and be
converted into and exchanged for the right to receive shares of City National
Stock, cash, or a mixture of City National Stock and cash, in a ratio specified
in the Agreement. Dissenting shares shall not be converted into the right to
receive shares of City National Stock, but shall be entitled to such rights as
are granted under the California General Corporation Law. No fractional shares
of City National Stock shall be issued in the Merger, but instead fractional
shares shall be converted to cash under a formula in the Agreement.
 
    The Agreement also refers to possible mergers of Ventura's wholly-owned
subsidiaries Ventura County National Bank and/or Frontier Bank, N.A., with or
into City National's wholly-owned subsidiary City National Bank at some time or
times after the Merger ("Bank Mergers"). These transactions are said to be
undertaken at City National's discretion. The Agreement does not specify the
timing, conditions, form, or any other facets of these potential
subsidiary-level transactions. This letter addresses solely the Merger and
assumes that, if one or more Bank Mergers occur, such Bank Mergers will not have
the effect of disqualifying the Merger as a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code").
 
                                      C-1
<PAGE>
    Our analysis and the opinions set forth herein are based upon the facts as
set forth in that certain Agreement referred to above, including the exhibits
thereto. Our opinions are also based on certain representations in the Agreement
and the Shareholders' Agreement, certain written representations to us from
Ventura and City National in letters of even date herewith, and certain written
representations to us in letters from the person who is a Ventura shareholder
holding at least 5% of Ventura's issued and outstanding stock. The facts
contained in the above-referenced documents are incorporated herein by reference
as the operative facts underlying the tax opinions set forth herein. One of our
key assumptions for purposes of this letter is that the facts set forth in those
documents are accurate on the date of this analysis and remain accurate to the
date of the closing of the Merger and are otherwise true, complete, and correct.
Any change or inaccuracy in such facts may adversely affect our opinions.
 
    We have acted as special counsel to Ventura in connection with the Merger
and are rendering these opinions to Ventura at its request. In rendering these
opinions, we have examined such documents, laws, regulations and other legal
matters as we have considered necessary or appropriate for purposes of the
opinions expressed herein. We have not made any independent investigation in
rendering these opinions other than as described herein.
 
    Our opinions are based upon the Code as of the date hereof and currently
applicable Treasury Regulations promulgated under the Code (including proposed
Treasury Regulations), published administrative positions of the Internal
Revenue Service in revenue rulings and revenue procedures, and judicial
decisions. Such legal authorities are all subject to change, either
prospectively or retroactively. No assurance can be provided as to the effect of
any such change upon our opinions.
 
    The opinions set forth herein have no binding effect on the Internal Revenue
Service or the courts. No assurance can be given that, if contested, a court
would agree with the opinions set forth herein. The opinions set forth herein
represent rather our best legal judgment as to the likely outcome of the issues
addressed herein if such issues were litigated.
 
    In the case of a transaction as complex as the Merger, many federal, state
and local income and other tax consequences arise. We have been asked only to
address the issues specifically set forth below. No opinion is expressed
regarding any other issues.
 
    This letter is being issued solely for the benefit of Ventura and for the
benefit of the Ventura shareholders as of the date of the Merger. It may not be
relied upon by any other person without our prior written consent.
 
    Subject to the foregoing, it is our opinion that the Merger qualifies as a
reorganization within the meaning of Section 368(a) of the Code, and that
Ventura and City National are parties to the reorganization within the meaning
of Section 368(b) of the Code.
 
    We hereby consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to a Registration Statement on Form S-4 to be
filed in connection with the Merger.
 
        Very truly yours,
 
        /s/ MANATT, PHELPS & PHILLIPS, LLP

                                   APPENDIX D
                             STOCK OPTION AGREEMENT
 
    THIS STOCK OPTION AGREEMENT, dated as of September 15, 1996 (the
"AGREEMENT"), is made and entered into by and between City National Corporation,
a Delaware corporation ("CNC"), and Ventura County National Bancorp, a
California corporation ("VCNB").
 
    WHEREAS, CNC and VCNB are concurrently herewith entering into an Agreement
and Plan of Merger with respect to a business combination of CNC and VCNB (the
"MERGER AGREEMENT"); and
 
    WHEREAS, as a condition to its willingness to enter into the Merger
Agreement, CNC has requested that VCNB agree, and in order to induce CNC to
enter into the Merger Agreement, VCNB has agreed, to grant an option to CNC to
purchase certain shares of common stock, no par value, of VCNB (the "VCNB COMMON
STOCK");
 
    NOW, THEREFORE, in consideration of the foregoing, and the representations,
warranties, covenants and agreements set forth herein and in the Merger
Agreement, and intending to be legally bound, the parties hereto agree as
follows:
 
    1.  GRANT OF OPTION.  VCNB hereby grants to CNC an irrevocable option (the
"OPTION") to purchase, subject to the terms hereof, up to 1,836,516 fully paid
and nonassessable shares (the "OPTION SHARES") of VCNB Common Stock, exercisable
as set forth herein by payment of the Option Price, as defined in Section 4
hereof. The number of shares of VCNB Common Stock that may be received upon the
exercise of the Option and the Option Price are subject to adjustment as set
forth herein.
 
    2.  EXERCISE OF OPTION.
 
    (a) CNC may, subject to the provisions of this Section 2 and subject to the
conditions of exercise contained in Section 3 hereof, exercise the Option, in
whole or in part, at any time following the occurrence of an Exercise Event, but
prior to the Expiration Date (as defined in Section 3 hereof).
 
    (b) Notwithstanding any other provision of this Agreement to the contrary,
in no event shall CNC purchase under the terms of this Agreement that number of
Option Shares which have a Spread Value in excess of $2,000,000. In the event
the Spread Value exceeds $2,000,000 the number of Option Shares which CNC is
entitled to purchase at the Closing Date shall be reduced to the extent required
such that the Spread Value following such reduction is equal to or less than
$2,000,000.
 
    3.  CONDITIONS OF EXERCISE; EXPIRATION.
 
    (a) It shall be a condition to CNC's exercise of the Option that, at the
time of such exercise (i) CNC is not in breach in any material respect of any
covenant or obligation set forth in the Merger Agreement and (ii) there is not
in effect any preliminary or permanent injunction or other order by any court of
competent jurisdiction which prevents or restrains the issuance and delivery of
the Option Shares.
 
    (b) The right to exercise any part of the Option not previously exercised
shall expire, terminate and be of no further force and effect upon the earliest
to occur of (such earliest date, the "EXPIRATION DATE") (i) the Effective Time
of the Merger, (ii) the date the Merger Agreement is terminated pursuant to
Sections 8.1(a) or (g); (iii) the date the Merger Agreement is terminated by
VCNB or CNC pursuant to Sections 8.1(b), (c), (d), (e) or (f) if such date is
prior to the occurrence of an Exercise Event or Preliminary Acquisition
Transaction; or (iv) 18 months following the earliest to occur of (A) the date
of any termination of the Merger Agreement other than as described in clauses
(ii) and (iii) of this sentence or (B) the date of the first occurrence of an
Exercise Event.
 
    4.  MANNER OF EXERCISE.
 
    (a) In the event that CNC wishes to exercise the Option, in whole or in
part, CNC shall send a written notice (the date of which being herein referred
to as the "NOTICE DATE") to VCNB, specifying the
 
                                      D-1
<PAGE>
number of Option Shares to be purchased and a place and date not earlier than
two nor later than ten business days following any such Notice Date for the
closing of such purchase (the "CLOSING"); provided that if prior notification to
or approval of the Federal Reserve Board, the Office of the Comptroller of the
Currency (the "OCC") or any other regulatory agency is required in connection
with such purchase, each party shall cooperate with the other in the filing of
the required notice or application for approval and shall expeditiously process
the same and use its reasonable best efforts, in good faith, to obtain any
required approval; and the period of time that otherwise would run pursuant to
this sentence shall run instead from the date on which any required notification
periods have expired or been terminated or such approvals have been obtained and
any requisite waiting period or periods shall have passed.
 
    (b) At any Closing, CNC will make payment to VCNB for the Option Shares so
purchased at such date by delivery of immediately available funds to VCNB of
$3.93 per Option Share (the "OPTION PRICE"). If the Option is exercised in part
only, CNC shall also deliver this Agreement to VCNB at the Closing in exchange
for a new agreement duly authorized and executed by VCNB identical to this
Agreement evidencing the right to purchase the remaining balance of the Option
Shares.
 
    (c) Upon payment of the Option Price, VCNB will immediately deliver to CNC a
certificate or certificates representing such Option Shares registered in the
name of CNC or its assignee or designee.
 
    (d) Certificates for Option Shares delivered at a Closing hereunder may be
endorsed with a restrictive legend that shall read substantially as follows:
 
       "The transfer of the shares represented by this certificate is
       subject to certain provisions of an agreement between the
       registered holder hereof and the issuer and to resale restrictions
       arising under the Securities Act of 1933, as amended. A copy of
       such agreement is on file at the principal office of the issuer
       and will be provided to the holder hereof without charge upon
       receipt by Issuer of a written request therefor."
 
    It is understood and agreed that: (i) the reference to the resale
restrictions of the Securities Act of 1933, as amended (the "SECURITIES ACT"),
in the above legend shall be removed by delivery of substitute certificate(s)
without such reference if CNC shall have delivered to VCNB a copy of a letter
from the staff of the Securities and Exchange Commission ("SEC"), or an opinion
of counsel, in form and substance reasonably satisfactory to VCNB, to the effect
that such legend is not required for purposes of the Securities Act; (ii) the
reference to the provisions of this Agreement in the above legend shall be
removed by delivery of substitute certificate(s) without such reference if the
shares have been sold or transferred in compliance with the provisions of this
Agreement and under circumstances that do not require the retention of such
reference; and (iii) the legend shall be removed in its entirety if the
conditions in the preceding clauses (i) and (ii) are both satisfied. In
addition, such certificates shall bear any other legend as may be required by
law.
 
    5.  REGISTRATION OF SHARES.
 
    (a) In the event that the Option has become exercisable in accordance with
Section 2 hereof, then, as promptly as practicable upon CNC's request, but, in
any event, within six months from the date of CNC's request, VCNB agrees to
prepare and file a registration statement ("REGISTRATION EVENT") under the
Securities Act, and any applicable state securities laws, with respect to any
proposed disposition by CNC of any or all of the Option Shares and to use its
best efforts to cause such registration statement to become effective as
expeditiously as possible and to keep such registration effective for a period
of not less than ninety days, unless, in the written opinion of counsel to VCNB,
addressed to CNC and which shall be satisfactory in form and substance to CNC
and its counsel, registration is not required for such proposed disposition of
the Option Shares. Notwithstanding the foregoing, VCNB shall have the right to
delay (the "DELAY RIGHT") a Registration Event for a period of up to sixty (60)
days in the event it receives a request from CNC to effect a Registration Event
if VCNB (i) is involved in a material transaction, or (ii) determines, in the
good faith exercise of its reasonable business judgment, that such registration
and offering could adversely effect or interfere with BONA FIDE material
financing plans of VCNB or would
 
                                      D-2
<PAGE>
require disclosure of information, the premature disclosure of which could
materially adversely affect VCNB or any transaction under active consideration
by VCNB. For purposes of this Agreement, the term "material transaction" shall
mean a transaction which would require VCNB to file a current report on Form 8-K
with the SEC. VCNB shall have the right to exercise two (2) Delay Rights in any
twelve (12) month period. All fees, expenses and charges of any kind or nature
whatsoever incurred in connection with the registration of the Option Shares
pursuant to this Section 5 shall be borne and paid by VCNB. VCNB shall indemnify
and hold harmless CNC, its affiliates and its officers, directors, attorneys and
agents from and against any and all losses, claims, damages, liabilities and
expenses (including, without limitation, all out-of-pocket expenses,
investigation expenses, expenses incurred with respect to any judgment and fees,
charges and disbursements of counsel and accountants) arising out of or based
upon any statements contained in, or omissions or alleged omissions from, each
registration statement (and related prospectus) required to be filed pursuant to
this Section 5.
 
    (b) CNC shall be limited to the benefit of two effective demand
registrations as described in Section 5(a) to be requested during the three (3)
years following the date of the first Exercise Event, but shall have an
unlimited number of so-called "piggyback" registration rights. VCNB agrees to
enter into a Registration Rights agreement with CNC containing customary terms,
including appropriate indemnities, which shall only allow underwriters the
ability to cut back the number of shares CNC seeks to have registered on pro
rata basis.
 
    6.  REPRESENTATIONS AND WARRANTIES OF VCNB.  VCNB hereby represents and
warrants to, and agrees with, CNC as follows:
 
    (a)  AUTHORITY RELATIVE TO THIS AGREEMENT.  VCNB has full corporate power
and authority to execute and deliver this Agreement and to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement
and the consummation of the transactions contemplated hereby have been duly and
validly authorized by the Board of Directors of VCNB and no other corporate
proceedings on the part of VCNB are necessary to authorize this Agreement or to
consummate the transactions so contemplated. This Agreement has been duly and
validly executed and delivered by VCNB and, assuming that this Agreement has
been duly and validly authorized, executed and delivered by CNC, this Agreement
constitutes a valid and binding agreement of VCNB, enforceable against VCNB in
accordance with its terms.
 
    (b)  OPTION SHARES.  VCNB has taken all necessary corporate action to
authorize and reserve and to permit it to issue, and at all times from the date
hereof through the Expiration Date will have reserved for issuance upon exercise
of the Option, 1,836,516 shares of Common Stock, each of which, upon delivery
pursuant hereto, shall be duly authorized, validly issued, fully paid and
nonassessable, and shall be delivered free and clear of all claims, liens,
encumbrances and security interests and not be subject to any preemptive rights.
VCNB will take all necessary corporate action to authorize and reserve for
issuance upon exercise of the Option such additional shares as may be required
pursuant to Section 9 hereof. VCNB will not take, and will refrain from taking,
any action which could have the effect of preventing or disabling VCNB from (i)
delivery of the Option Shares to CNC upon exercise of the Option or (ii) from
otherwise performing its obligations under this Agreement.
 
    (c)  CONFLICTING INSTRUMENTS; CONSENTS.  Neither the execution and delivery
of this Agreement nor the consummation of the transactions contemplated hereby
will violate or result in any violation of or be in conflict with or constitute
a default under any term of the Articles of Incorporation or Bylaws of VCNB, or
of any material agreement, instrument, judgment, decree, order, statute, rule or
governmental regulation applicable to VCNB. No consent or approval by any
governmental authority, other than compliance with applicable federal and state
securities and banking laws, and regulations of the Federal Reserve Board and
the OCC, is required of VCNB in connection with the execution and delivery by
VCNB of this Agreement or the consummation by VCNB of the transactions
contemplated hereby.
 
                                      D-3
<PAGE>
    (d)  NOTICE.  VCNB shall give notice to CNC promptly, but in any event
within 10 days of VCNB's first obtaining knowledge of any Exercise Event or
Repurchase Event.
 
    7.  REPRESENTATIONS AND WARRANTIES OF CNC.  CNC hereby represents and
warrants to VCNB as follows:
 
    (a)  AUTHORITY RELATIVE TO THIS AGREEMENT.  CNC has full corporate power and
authority to execute and deliver this Agreement and to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement
and the consummation of the transactions contemplated hereby have been duly and
validly authorized by the Board of Directors of CNC and no other corporate
proceedings on the part of CNC are necessary to authorize this Agreement or to
consummate the transactions so contemplated. This Agreement has been duly and
validly executed and delivered by CNC and, assuming this Agreement has been duly
and validly authorized, executed and delivered by VCNB, this Agreement
constitutes a valid and binding agreement of CNC, enforceable against CNC in
accordance with its terms.
 
    (b)  NO DISTRIBUTION.  CNC will acquire the Option Shares issued upon
exercise of the Option for its own account, without a view toward the
distribution thereof, and will not sell such Option Shares unless such sale is
registered under the Securities Act or unless an exemption from such
registration is available.
 
    8.  NOTIFICATION OF RECORD DATE; POSTPONEMENT OF MEETING.  At any time
during the period that this Option may become exercisable by CNC, VCNB shall
give CNC thirty business days' prior written notice of any record date, for
determining the holders of record of VCNB Common Stock entitled to vote on any
matter, to receive any dividend or distribution, or to receive any other benefit
or right, or for any other purpose that a record date is taken or declared with
respect to the VCNB Common Stock. In the event that CNC, in accordance with this
Agreement, elects to exercise the Option granted hereunder by delivery of the
notice required pursuant to Section 4 after the record date set by VCNB for any
shareholders' meeting, then VCNB shall, upon request by CNC, cancel the
scheduled meeting and its related record date and reschedule it for a later
date; provided, however, that the record date for such rescheduled meeting shall
be a date that is not fewer than ten nor more than thirty business days after
the cancellation of the originally scheduled shareholders' meeting.
 
    9.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION, ETC.
 
    (a) In the event of any dividend, stock split, split-up, recapitalization,
reclassification, combination, exchange of shares or similar transaction or
event with respect to the VCNB Common Stock, the type and number of shares or
securities subject to the Option, and the Option Price therefor, shall be
adjusted appropriately, and proper provision shall be made in the agreements
governing such transaction so that CNC shall receive, upon exercise of the
Option, the number and class of shares or other securities or property that CNC
would have received in respect of VCNB Common Stock if the Option had been
exercised immediately prior to such event, or the record date therefor, as
applicable. If any shares of VCNB Common Stock are issued after the date of this
Agreement (other than pursuant to an event described in the first sentence of
this Section 9(a)), the number of shares of VCNB Common Stock subject to the
Option shall be adjusted so that, after such issuance, it, together with any
shares of VCNB Common Stock previously issued to CNC pursuant hereto, equals
19.9% of the number of shares of VCNB Common Stock then issued and outstanding,
without giving effect to any shares subject to or issued pursuant to this
Option.
 
    (b) In the event that VCNB shall, prior to the Expiration Date, enter in an
agreement: (i) to consolidate with or merge into any person, other than CNC or
one of its Subsidiaries, and shall not be the continuing or surviving
corporation of such consolidation or merger, (ii) to permit any person, other
than CNC or one of its Subsidiaries, to merge into VCNB and VCNB shall be the
continuing or surviving corporation, but, in connection with such merger, the
then outstanding shares of VCNB Common Stock shall be changed into or exchanged
for stock or other securities of VCNB or any other person or cash or any other
property or the outstanding shares of VCNB Common Stock immediately prior to
such merger shall after such merger represent less than 50% of the outstanding
shares and share equivalents of the
 
                                      D-4
<PAGE>
merged company; or (iii) to sell or otherwise transfer all or substantially all
of its assets to any person, other than CNC or one of its Subsidiaries, then,
and in each such case, the agreement governing such transaction shall make
proper provisions so that the Option shall, upon the consummation of any such
transaction and upon the terms and conditions set forth herein, be converted
into, or exchanged for, an option (the "SUBSTITUTE OPTION"), at the election of
CNC, of either (x) the Acquiring Corporation (as defined below), (y) any person
that controls the Acquiring Corporation, or (z) in the case of a merger
described in clause (ii), VCNB (in each case, such person being referred to as
the "SUBSTITUTE OPTION ISSUER").
 
    (c) The Substitute Option shall have the same terms as the Option, PROVIDED
that, if the terms of the Substitute Option cannot, for legal reasons, be the
same as the Option, such terms shall be as similar as possible and in no event
less advantageous to CNC. The Substitute Option Issuer shall also enter into an
agreement with the then-holder or holders of the Substitute Option in
substantially the same form as this Agreement, which shall be applicable to the
Substitute Option.
 
    (d) The Substitute Option shall be exercisable for such number of shares of
the Substitute Common Stock (as hereinafter defined) as is equal to the Assigned
Value (as hereinafter defined) multiplied by the number of shares of the VCNB
Common Stock for which the Option was theretofore exercisable, divided by the
Average Price (as hereinafter defined). The exercise price of the Substitute
Option per share of the Substitute Common Stock (the "SUBSTITUTE OPTION PRICE")
shall then be equal to the Option Price multiplied by a fraction in which the
numerator is the number of shares of the VCNB Common Stock for which the Option
was theretofore exercisable and the denominator is the number of shares for
which the Substitute Option is exercisable.
 
    (e) The following terms have the meanings indicated:
 
         (i)  "ACQUIRING CORPORATION" shall mean (x) the continuing or surviving
    corporation of a consolidation or merger with VCNB (if other than VCNB), (y)
    VCNB in a merger in which VCNB is the continuing or surviving person, and
    (z) the transferee of all or any substantial part of the VCNB's assets (or
    the assets of its Subsidiaries).
 
         (ii)  "SUBSTITUTE COMMON STOCK" shall mean the common stock issued by
    the Substitute Option Issuer upon exercise of the Substitute Option.
 
        (iii)  "ASSIGNED VALUE" shall mean the highest of (x) the price per
    share of the VCNB Common Stock at which a Tender Offer or Exchange Offer
    therefor has been made by any person (other than CNC or its Subsidiaries),
    (y) the price per share of the VCNB Common Stock to be paid by any person
    (other than CNC or its Subsidiaries) pursuant to an agreement with VCNB, and
    (z) the highest closing sales price per share of VCNB Common Stock quoted on
    the Nasdaq National Market (or if VCNB Common Stock is not quoted on the
    Nasdaq National Market, the highest bid price per share on any day as quoted
    on the principal trading market or securities exchange on which such shares
    are traded as reported by a recognized source chosen by CNC) within the
    six-month period immediately preceding the agreement; PROVIDED, that in the
    event of a sale of less than all of VCNB's assets, the Assigned Value shall
    be the sum of the price paid in such sale for such assets and the current
    market value of the remaining assets of VCNB as determined by a nationally
    recognized investment banking firm selected by CNC and reasonably acceptable
    to VCNB, divided by the number of shares of the VCNB Common Stock
    outstanding at the time of such sale. In the event that an Exchange Offer is
    made for the VCNB Common Stock or an agreement is entered into for a merger
    or consolidation involving consideration other than cash, the value of the
    securities or other property issuable or deliverable in exchange for the
    VCNB Common Stock shall be determined by a nationally recognized investment
    banking firm mutually selected by CNC and VCNB (or if applicable, Acquiring
    Corporation), provided that if a mutual selection cannot be made as to such
    investment banking firm, it shall be selected by CNC.
 
                                      D-5
<PAGE>
        (iv)  "AVERAGE PRICE" shall mean the average closing price of a share of
    the Substitute Common Stock for the one year immediately preceding the
    consolidation, merger or sale in question, but in no event higher than the
    closing price of the shares of the Substitute Common Stock on the day
    preceding such consolidation, merger or sale, PROVIDED that if VCNB is the
    issuer of the Substitute Option, the Average Price shall be computed with
    respect to a share of common stock issued by VCNB, the person merging into
    VCNB or by any company which controls or is controlled by such merging
    person, as CNC may elect.
 
    (f) In no event pursuant to any of the foregoing paragraphs shall the
Substitute Option be exercisable for more than 19.9% of the aggregate of the
shares of the Substitute Common Stock outstanding prior to exercise of the
Substitute Option. In the event that the Substitute Option would be exercisable
for more than 19.9% of the aggregate of the shares of Substitute Common Stock
but for this clause (f), the Substitute Option Issuer shall make a cash payment
to CNC equal to the excess of (i) the value of the Substitute Option without
giving effect to the limitation in this clause (f) over (ii) the value of the
Substitute Option after giving effect to the limitation in this clause (f). This
difference in value shall be determined by a nationally recognized investment
banking firm selected by CNC.
 
    (g) VCNB shall not enter into any transaction described in subsection (b) of
this Section 9 unless the Acquiring Corporation and any person that controls the
Acquiring Corporation assume in writing all the obligations of VCNB hereunder
and take all other actions that may be necessary so that the provisions of this
Section 9 are given full force and effect (including, without limitation, any
action that may be necessary so that the shares of Substitute Common Stock are
in no way distinguishable from or have lesser economic value than other shares
of common stock issued by the Substitute Option Issuer).
 
    10.  REPURCHASE AT THE OPTION OF CNC.
 
    (a) At the written request of CNC at any time commencing upon the first
occurrence of a Repurchase Event (as defined in Section 10(d)), VCNB shall
repurchase from CNC the Option and, to the extent permitted by the California
General Corporation Law, all shares of VCNB Common Stock purchased by CNC
pursuant hereto with respect to which CNC then has Beneficial Ownership. The
date on which CNC exercises its rights under this Section 10 is referred to as
the "REQUEST DATE", and the Request Date must be no later than 12 months after
the first occurrence of a Repurchase Event. Such repurchase shall be at an
aggregate price (the "REPURCHASE CONSIDERATION") equal to the sum of:
 
        (i) the aggregate Option Price paid by CNC for any shares of VCNB Common
    Stock acquired pursuant to the Option with respect to which CNC then has
    Beneficial Ownership;
 
        (ii) the excess, if any, of (x) the Applicable Price (as defined below)
    for each share of VCNB Common Stock over (y) the Option Price (subject to
    adjustment pursuant to Section 9), multiplied by the number of shares of
    VCNB Common Stock with respect to which the Option has not been exercised;
    and
 
       (iii) the excess, if any, of the Applicable Price over the Option Price
    (subject to adjustment pursuant to Section 9) paid (or, in the case of
    Option Shares with respect to which the Option has been exercised but the
    Closing Date has not occurred, payable) by CNC for each share of VCNB Common
    Stock with respect to which the Option has been exercised and with respect
    to which CNC then has Beneficial Ownership, multiplied by the number of such
    shares; provided, that the amount calculated pursuant to clause (ii) and
    (iii) of this Section 10(a) shall not exceed $2,000,000.
 
    (b) If CNC exercises its rights under this Section 10, VCNB shall, within
ten business days after the Request Date, pay the Repurchase Consideration to
CNC in immediately available funds, and contemporaneously with such payment CNC
shall surrender to VCNB the Option and the certificates evidencing the shares of
VCNB Common Stock purchased thereunder with respect to which CNC then has
Beneficial Ownership, and CNC shall warrant that it has sole record and
Beneficial Ownership of such shares and that the same are then free and clear of
all liens, claims, charges and encumbrances of any kind whatsoever.
Notwithstanding the foregoing, to the extent that prior notification to or
approval of the
 
                                      D-6
<PAGE>
Federal Reserve Board, the OCC or other regulatory authority is required in
connection with the payment of all or any portion of the Repurchase
Consideration, CNC shall have the ongoing option to revoke its request for
repurchase pursuant to this Section 10, in whole or in part, or to require that
VCNB deliver from time to time that portion of the Repurchase Consideration that
it is not then so prohibited from paying and promptly file the required notice
or application for approval and expeditiously process the same (and each party
shall cooperate with the other in the filing of any such notice or applicable
and the obtaining of any such approval). If the Federal Reserve Board, the OCC
or any other regulatory authority disapproves of any part of VCNB's proposed
repurchase pursuant to this Section 10, VCNB shall promptly give notice of such
fact to CNC. If the Federal Reserve Board, the OCC or other regulatory agency
prohibits the repurchase in part but not in whole, then CNC shall have the right
(i) to revoke the repurchase request or (ii) to the extent permitted by the
Federal Reserve Board, the OCC or other regulatory agency, determine whether the
repurchase should apply to the Option and/or Option Shares and to what extent to
each, and CNC shall thereupon have the right to exercise the Option as to the
number of Option Shares for which the Option was exercisable at the Request Date
less the sum of the number of shares covered by the Option in respect of which
payment has been made pursuant to Section 10(a)(ii) and the number of shares
covered by the portion of the Option (if any) that has previously been
repurchased. CNC shall notify VCNB of its determination under the preceding
sentence within five business days of receipt of notice of disapproval of the
repurchase.
 
    Notwithstanding anything herein to the contrary, all of CNC's rights with
respect to any unexercised Options under this Section 10 shall terminate on the
Expiration Date.
 
    (c) For purposes of this Agreement, the "Applicable Price" means the highest
of (i) the highest price per share of VCNB Common Stock paid for any such share
by the person or groups described in Section 10(d)(i), (ii) the price per share
of VCNB Common Stock received by holders of VCNB Common Stock in connection with
any merger or other business combination transaction described in Section
9(b)(i), 9(b)(ii) or 9(b)(iii), or (iii) the highest closing sales price per
share of VCNB Common Stock quoted on the Nasdaq National Market (or if VCNB
Common Stock is not quoted on the Nasdaq National Market, the highest bid price
per share as quoted on the principal trading market or securities exchange on
which such shares are traded as reported by a recognized source chosen by CNC)
during the 60 business days preceding the Request Date; PROVIDED, HOWEVER, that
in the event of a sale of less than all of VCNB's assets, the Applicable Price
shall be the sum of the price paid in such sale for such assets and the current
market value of the remaining assets of VCNB as determined by an independent
national recognized investment banking firm selected by CNC and reasonably
acceptable to VCNB (which determination shall be conclusive for all purposes of
this Agreement), divided by the number of shares of the VCNB Common Stock
outstanding at the time of such sale. If the consideration to be offered, paid
or received pursuant to either of the foregoing clauses (i) or (ii) shall be
other than in cash, the value of such consideration shall be determined in good
faith by an independent nationally recognized investment banking firm selected
by CNC and reasonably acceptable to VCNB, which determination shall be
conclusive for all purposes of this Agreement.
 
    (d) As used herein, "REPURCHASE EVENT" shall occur if (i) any person (other
than CNC or any subsidiary of CNC) shall have acquired Beneficial Ownership, or
the right to acquire Beneficial Ownership, or any "group" (as such term is
defined under the Exchange Act) shall have been formed which Beneficially Owns
or has the right to acquire Beneficial Ownership, of 50% or more of the then-
outstanding shares of VCNB Common Stock, (ii) any of the transactions described
in Section 9(b)(i), 9(b)(ii) or 9(b)(iii) shall be consummated, or (iii)
following an Exercise Event, CNC receives official notice that an approval of
the Federal Reserve Board or any other regulatory authority required for the
exercise of the Option and purchase of the Option Shares will not be issued or
granted.

Board of Directors

Directors:
 
   
    You have requested our opinion as to the fairness, from a financial point of
view, to the holders of the outstanding shares of common stock, no par value
(the "Shares"), of Ventura County National Bancorp ("Company") of the
consideration to be paid to them for the Shares (the "Consideration") pursuant
to the Agreement and Plan of Merger, dated as September 15, 1996, by and between
City National Corporation ("CNC") and the Company (the "Agreement").
    
 
   
    Under the terms of the Agreement, the Company will be merged with and into
CNC (the "Merger") and each Share issued and outstanding immediately prior to
the Merger will be converted into the right to receive, at the election of the
holder thereof, either: (a) cash in the amount of $5.03 per Share (the "Cash
Amount"); or (b) a fraction of a share of CNC common stock, par value $1.00 per
share ("CNC Common Stock"), equal to the quotient (such quotient, the "Exchange
Ratio") of $5.03 divided by the average daily closing price of CNC Common Stock
for the 20 consecutive trading days immediately preceding the third day prior to
the effective time of the Merger (the "CNC Final Stock Price"), subject to a
minimum Exchange Ratio of .2634 and a maximum Exchange Ratio of .3214 (the
"Stock Amount"). Holders of Shares will be permitted to elect to receive either
the Cash Amount, the Stock Amount or a combination thereof. Such elections will
be subject to proration as necessary to ensure that 55% of the Shares are
converted into CNC Common Stock. The Company may terminate the Agreement if the
CNC Final Stock Price is less than $13.90 per share. The Merger is intended to
qualify as a tax-free reorganization within the meaning of Section 368 of the
Internal Revenue Code.
    
 
   
    Sandler O'Neill & Partners, L.P., as part of its investment banking
business, is regularly engaged in the valuation of financial institutions and
their securities in connection with mergers and acquisitions and other corporate
transactions.
    
 
   
    In connection with this opinion, we have reviewed, among other things: (i)
the Agreement and exhibits thereto; (ii) the Stock Option Agreement dated as of
September 15, 1996 by and between the Company and CNC; (iii) a draft of the
Proxy Statement-Prospectus to be mailed to the Company's shareholders in
connection with the Merger; (iv) the audited consolidated financial statements
and management's discussion and analysis of the financial condition and results
of operations of each of the Company, CNC and Riverside National Bank
("Riverside") for the three years ended December 31, 1995; (v) the unaudited
consolidated financial statements and management's discussion and analysis of
the financial condition and results of operations for the interim periods ending
March 31, June 30, and September 30, 1996 of each of the Company, CNC and
Riverside; (vi) financial analyses and forecasts for each of the Company and CNC
prepared by and/or reviewed with the respective managements of the Company and
CNC; (vii) the views of senior management of each of the Company and CNC of the
past and current business operations, results thereof, financial condition and
future prospects of their respective companies; (viii) the dividend payment
practices and policies of CNC; (ix) the reported price and

trading activity for the Company's common stock and CNC's Common Stock,
including a comparison of certain financial and stock market information for the
Company and CNC with similar information for certain other companies the
securities of which are publicly traded; (x) the financial terms of recent
business combinations in the banking industry; (xi) the pro forma impact of the
Merger and CNC's pending acquisition of Riverside on CNC, (xii) the current
market environment generally and the banking environment in particular, and
(xiii) such other information, financial studies, analyses and investigations
and financial, economic and market criteria as we considered relevant, including
the intended tax deferred nature of the Merger, the potential benefits of the
cash or stock election to the holders of the Shares and Ventura's recent history
of inconsistent profitability and uncertain future profitability.
    
 
   
    In performing our review, we have assumed and relied upon, without
independent verification, the accuracy and completeness of all of the financial
information, analyses and other information reviewed by and discussed with us,
and we did not make any independent evaluation or appraisal of specific assets,
the collateral securing assets or the liabilities of the Company, CNC or
Riverside or any of their subsidiaries, or the collectibility of any such assets
(relying, where relevant, on the analyses and estimates of the Company and CNC).
With respect to the financial projections reviewed with management, we have
assumed that they have been reasonably prepared on bases reflecting the best
currently available estimates and judgments of the respective managements of the
respective future financial performances of each of the Company and CNC, and
that such performances will be achieved. We have also assumed that there has
been no material change in the Company's or CNC's assets, financial condition,
results of operations, business or prospects since the date of the last
financial statements made available to us. We have further assumed that the
Company will remain as a going concern for all periods relevant to our analysis,
and that the conditions precedent to the Company's obligations under the
Agreement are not waived.
    
 
   
    Our opinion is necessarily based on economic, market and other conditions as
in effect on, and the information made available to us as of, the date hereof.
Events occurring after the date hereof could materially affect the assumptions
used in preparing this opinion. We have not undertaken to reaffirm or revise
this opinion or otherwise comment upon any events occurring after the date
hereof.
    
 
    We have acted as the Company's financial advisor in connection with the
Merger and will receive a fee for our services, a significant portion of which
is contingent upon the consummation of the Merger. We have also received a fee
for rendering this opinion. We have also provided general financial advisory
services for the Company and have received fees for such services.
 
    In the ordinary course of our business, we may actively trade the equity
securities of both the Company and CNC for our own account and for the accounts
of our customers and, accordingly, may at any time hold a long or short position
in such securities.
 
   
    It is understood that this opinion is not to be quoted or referred to, in
whole or in part, in a registration statement, prospectus or proxy statement, or
in any other document used in connection with the offering or sale of
securities, no shall this letter be quoted or referred to in any other document
or for any other purposes, without Sandler O'Neill's prior written consent.
    
 
    Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the Consideration to be paid by CNC to the holders of the Shares
pursuant to the Agreement is fair, from a financial point of view, to such
holders.
 
   
                                          Very truly yours,

ITEM 1.  BUSINESS
 
GENERAL
 
    The Company is a registered bank holding company conducting business through
its two subsidiary banks, Ventura County National Bank ("Ventura") and Frontier
Bank, N.A. ("Frontier"). (Ventura and Frontier are sometimes collectively
referred to herein as the "Banks"). At December 31, 1995, the Company had total
consolidated assets of $267.8 million, total consolidated deposits of $236.1
million and total consolidated shareholders' equity of $29.5 million. The
principal executive offices of the Company are located at 500 Esplanade Drive,
Oxnard, California 93030, and its telephone number at that address is (805)
981-2600.
 
    The Banks are both national banking associations operating in Southern
California. Ventura conducts its banking operations through four branch offices
located in Ventura County, California, approximately 60 miles northwest of
downtown Los Angeles. Ventura's headquarters are located in Oxnard, California,
and its branch offices are located in Oxnard, Ventura, Camarillo and Westlake
Village. Frontier is based in La Palma in northwestern Orange County and has a
branch office in Wilmington in southern Los Angeles County. The Banks provide
commercial banking services to small to medium sized businesses, professional
firms and individuals in their market areas.
 
COMPETITION
 
    In an environment of heightened regulatory scrutiny with respect to insured
depository institutions such as Ventura and Frontier and expanded bank-like
services provided by limited service financial institutions and by nonbank
financial service providers, banking and bank related services continue to be an
industry of rapid change and intense competition, thereby creating a highly
competitive environment for the Company. Large moneycenter banks, super-regional
banks, regional banks, multinational banks and mutual funds are the Company's
primary competitors. Higher lending limits, wide-reaching advertising campaigns,
and access to international money markets allows these organizations greater
flexibility in meeting the needs of their customers. The Company competes for
deposits and loans with these organizations as well as with local banks, savings
and loans, savings banks, credit unions, thrift associations, and mortgage and
finance companies. The Company believes its marketing niche to be small and
medium-sized businesses with revenues less than $25 million. In order to compete
with the other financial institutions in its service areas, the Company
principally relies upon local promotional activities, personal relationships
established by officers, directors and employees with its customers, and
specialized services tailored to meet its customers' needs. In those instances
where the Company is unable to accommodate all of a customer's needs because of
regulatory restrictions, the Company will arrange for those services to be
provided by its correspondent banks or other companies with whom it has a
relationship.
 
    Bank of America, N.T. & S.A. and First Interstate Bank of California are the
dominant competitors in both Ventura and Frontier's market areas. First
Interstate Bank of California and Wells Fargo & Company have received regulatory
approval for a merger and the resulting institution will likely be a dominant
competitor in the market areas of both Banks. As of most recent data available,
Ventura had approximately 5% of total bank deposits in Ventura County, while
Frontier's share of total bank deposits in Orange County was 0.17% and Los
Angeles County was 0.8%.
 
EFFECT OF GOVERNMENTAL POLICIES AND RECENT LEGISLATION
 
    Banking is a business that depends on rate differentials. In general, the
difference between the interest rate paid by the Banks on their deposits and
their other borrowings and the interest rate received by the Banks on loans
extended to their customers and securities held in the Banks' portfolios
comprise the major portion of the Company's earnings. These rates are highly
sensitive to many factors that are beyond
 
                                      F-3
<PAGE>
the control of the Banks. Accordingly, the earnings and growth of the Company
are subject to the influence of domestic and foreign economic conditions,
including inflation, recession and unemployment.
 
    The commercial banking business is not only affected by general economic
conditions but is also influenced by the monetary and fiscal policies of the
federal government and the policies of regulatory agencies, particularly the
Board of Governors of the Federal Reserve System (the Federal Reserve Board").
The Federal Reserve Board implements national monetary policies (with objectives
such as curbing inflation and combating recession) by its open-market operations
in United States Government securities, by adjusting the required level of
reserves for financial institutions subject to its reserve requirements and by
varying the discount rates applicable to borrowings by depository institutions.
The actions of the Federal Reserve Board in these areas influence the growth of
bank loans, investments and deposits and also affect interest rates charged on
loans and paid on deposits. The nature and impact of any future changes in
monetary policies cannot be predicted.
 
    From time to time, legislation is enacted which has the effect of increasing
the cost of doing business, limiting or expanding permissible activities or
affecting the competitive balance between banks and other financial
institutions. Proposals to change the laws and regulations governing the
operations and taxation of banks, bank holding companies and other financial
institutions are frequently made in Congress, in the California legislature and
before various bank regulatory and other professional agencies. The Financial
Services Modernization Act recently proposed in the House of Representatives
would generally permit banks to expand activities further into the areas of
securities and insurance, and would reduce the regulatory and paperwork burden
that currently affects banks. Additionally, the proposed legislation would force
the conversion of savings and loan holding companies into bank holding
companies, although unitary savings and loan holding companies authorized to
engage in activities as of January 1, 1995 would be exempted. Similar
legislation has also been proposed in the Senate. In addition, legislation was
recently introduced in Congress that would merge the deposit insurance funds
applicable to commercial banks and savings associations and impose a one-time
assessment on savings associations to recapitalize the deposit insurance fund
applicable to savings associations. The likelihood of any major legislative
changes and the impact such changes might have on the Company are impossible to
predict. See "Item 1. Business-- Supervision and Regulation."
 
SUPERVISION AND REGULATION
 
    Bank holding companies and banks are extensively regulated under both
federal and state law. Set forth below is a summary description of certain laws
which relate to the regulation of the Company and the Banks. The description
does not purport to be complete and is qualified in its entirety by reference to
the applicable laws and regulations.
 
    THE COMPANY
 
    The Company, as a registered bank holding company, is subject to regulation
under the Bank Holding Company Act of 1956, as amended (the "BHC Act"). The
Company is required to file with the Federal Reserve Board quarterly and annual
reports and such additional information as the Federal Reserve Board may require
pursuant to the BHC Act. The Federal Reserve Board may conduct examinations of
the Company and its subsidiaries.
 
    The Federal Reserve Board may require that the Company terminate an activity
or terminate control of or liquidate or divest certain subsidiaries or
affiliates when the Federal Reserve Board believes the activity or the control
of the subsidiary or affiliate constitutes a significant risk to the financial
safety, soundness or stability of any of its banking subsidiaries. The Federal
Reserve Board also has the authority to regulate provisions of certain bank
holding company debt, including authority to impose interest ceilings and
reserve requirements on such debt. Under certain circumstances, the Company must
file written notice and obtain approval from the Federal Reserve Board prior to
purchasing or redeeming its equity securities.
 
                                      F-4
<PAGE>
    Under the BHC Act and regulations adopted by the Federal Reserve Board, a
bank holding company and its nonbanking subsidiaries are prohibited from
requiring certain tie-in arrangements in connection with any extension of
credit, lease or sale of property or furnishing of services. Further, the
Company is required by the Federal Reserve Board to maintain certain levels of
capital. See "Item 1. Business-- Supervision and Regulation--Capital Standards."
 
    The Company is required to obtain the prior approval of the Federal Reserve
Board for the acquisition of more than 5% of the outstanding shares of any class
of voting securities or substantially all of the assets of any bank or bank
holding company. Prior approval of the Federal Reserve Board is also required
for the merger or consolidation of the Company and another bank holding company.
 
    The Company is prohibited by the BHC Act, except in certain statutorily
prescribed instances, from acquiring direct or indirect ownership or control of
more than 5% of the outstanding voting shares of any company that is not a bank
or bank holding company and from engaging directly or indirectly in activities
other than those of banking, managing or controlling banks or furnishing
services to its subsidiaries. However, the Company, subject to the prior
approval of the Federal Reserve Board, may engage in any, or acquire shares of
companies engaged in, activities that are deemed by the Federal Reserve Board to
be so closely related to banking or managing or controlling banks as to be a
proper incident thereto. In making any such determination, the Federal Reserve
Board is required to consider whether the performance of such activities by the
Company or an affiliate can reasonably be expected to produce benefits to the
public, such as greater convenience, increased competition or gains in
efficiency, that outweigh possible adverse effects, such as undue concentration
of resources, decreased or unfair competition, conflicts of interest or unsound
banking practices. The Federal Reserve Board is also empowered to differentiate
between activities commenced DE NOVO and activities commenced by acquisition, in
whole or in part, of a going concern.
 
    Under Federal Reserve Board regulations, a bank holding company is required
to serve as a source of financial and managerial strength to its subsidiary
banks and may not conduct its operations in an unsafe or unsound manner. In
addition, it is the Federal Reserve Board's policy that in serving as a source
of strength to its subsidiary banks, a bank holding company should stand ready
to use available resources to provide adequate capital funds to its subsidiary
banks during periods of financial stress or adversity and should maintain the
financial flexibility and capital-raising capacity to obtain additional
resources for assisting its subsidiary banks. A bank holding company's failure
to meet its obligations to serve as a source of strength to its subsidiary banks
will generally be considered by the Federal Reserve Board to be an unsafe and
unsound banking practice or a violation of the Federal Reserve Board's
regulations or both. This doctrine has become known as the "source of strength"
doctrine. Although the United States Court of Appeals for the Fifth Circuit
found the Federal Reserve Board's source of strength doctrine invalid in 1990,
stating that the Federal Reserve Board had no authority to assert the doctrine
under the BHC Act, the decision, which is not binding on federal courts outside
the Fifth Circuit, was recently reversed by the United States Supreme Court on
procedural grounds. The validity of the source of strength doctrine is likely to
continue to be the subject of litigation until definitively resolved by the
courts or by Congress.
 
    The Company is also a bank holding company within the meaning of Section
3700 of the California Financial Code. As such, the Company and its subsidiaries
are subject to examination by, and may be required to file reports with, the
California State Banking Department. Regulations have not been adopted to
implement the powers of the California Superintendent of Banks under this
statute.
 
    Finally, the Company is subject to the periodic reporting requirements of
the Securities Exchange Act of 1934, as amended, including but not limited to,
filing annual, quarterly and other current reports with the Securities and
Exchange Commission.

    THE BANKS
 
    The Banks, as national banking associations, are subject to primary
supervision, examination and regulation by the Office of the Comptroller of the
Currency (the "OCC"). If, as a result of an examination of either Bank, the OCC
should determine that the financial condition, capital resources, asset quality,
earnings prospects, management, liquidity or other aspects of the Bank's
operations are unsatisfactory or that the Bank or its management is violating or
has violated any law or regulation, various remedies are available to the OCC.
Such remedies include the power to enjoin "unsafe or unsound practices," to
require affirmative action to correct any conditions resulting from any
violation or practice, to issue an administrative order that can be judicially
enforced, to direct an increase in capital, to restrict the growth of the Bank,
to assess civil monetary penalties, and to remove officers and directors. The
FDIC has similar enforcement authority, in addition to its authority to
terminate a Bank's deposit insurance in the absence of action by the OCC and
upon a finding that a Bank is in an unsafe or unsound condition, is engaging in
unsafe or unsound activities, or that its conduct poses a risk to the deposit
insurance fund or may prejudice the interest of its depositors.
 
    The deposits of the Banks are insured by the FDIC in the manner and to the
extent provided by law. For this protection, each Bank pays a semi-annual
statutory assessment and is subject to certain of the rules and regulations of
the FDIC. See "Item 1. Business--Supervision and Regulation--Premiums for
Deposit Insurance." The Banks are also subject to certain regulations of the
Federal Reserve Board and applicable provisions of California law, insofar as
they do not conflict with or are not preempted by federal banking law.
 
    Various other requirements and restrictions under the laws of the United
States and the State of California affect the operations of the Banks. Federal
and California statutes and regulations relate to many aspects of the Banks'
operations, including reserves against deposits, interest rates payable on
deposits, loans, investments, mergers and acquisitions, borrowings, dividends,
locations of branch offices, capital requirements and disclosure obligations to
depositors and borrowers. Further, the Banks are required to maintain certain
levels of capital. See "Item 1. Business--Supervision and Regulation--Capital
Standards."
 
    The OCC's statement of policy on risk-based capital requires that banks
maintain a ratio of qualifying total capital to risk-weighted assets of not less
than 8.00% (at least 4.00% of which must be in the form of Tier 1 capital). The
regulations set forth minimum requirements, and OCC has reserved the power to
require that banks maintain higher capital ratios. Among other powers, the OCC's
regulations provide that capital requirements may be enforced by the issuance of
a directive. The OCC's capital adequacy regulations also require that banks
maintain a minimum leverage ratio of 3.00% Tier 1 capital to total assets for
the most highly rated banks. This ratio is only a minimum. Institutions
experiencing or anticipating significant growth or those with other than minimum
risk profiles are expected to maintain a leverage ratio of at least 100 to 200
basis points above the minimum level. In addition, higher leverage ratios are
required to be considered well-capitalized or adequately capitalized under the
prompt corrective action provisions of the FDIC Improvement Act. For a more
complete description of the OCC's risk-based capital regulations, see
"Supervision and Regulation--Capital Standards" and "Supervision and
Regulation--Prompt Corrective Action and Other Enforcement Mechanisms."
 
    RESTRICTIONS ON TRANSFERS OF FUNDS TO THE COMPANY BY THE BANKS
 
    Federal Reserve Board policy prohibits a bank holding company from declaring
or paying a cash dividend which would impose undue pressure on the capital of
subsidiary banks or would be funded only through borrowings or other
arrangements that might adversely affect the holding company's financial
position. The policy further declares that a bank holding company should not
continue its existing rate of cash dividends on its common stock unless its net
income is sufficient to fully fund each dividend and its prospective rate of
earnings retention appears consistent with its capital needs, asset quality and
overall
 
                                      F-6
<PAGE>
financial condition. Other Federal Reserve Board policies forbid the payment by
bank subsidiaries to their parent companies of management fees which are
unreasonable in amount or exceed the fair market value of the services rendered
(or, if no market exists, actual cost plus a reasonable profit).
 
    The Company is a legal entity separate and distinct from the Banks. The
Company's ability to pay cash dividends is limited by state law. At present,
substantially all of the Company's revenues, including funds available for the
payment of dividends and other operating expenses, are earnings on investment of
cash at the parent Company. In the future, the Company's ability to pay cash
dividends will depend primarily on dividends paid by the Banks.
 
    There are statutory and regulatory limitations on the amount of dividends
which may be paid to the Company by the Banks. The prior approval of the
Comptroller is required if the total of all dividends declared by a national
bank in any calendar year exceeds the bank's net profits (as defined) for that
year combined with its retained net profits (as defined) for the preceding two
years, less any transfers to surplus. Under the prompt corrective action rules
of the Federal Deposit Insurance Corporation Improvement Act, no depository
institution, such as the Banks, may issue a dividend or pay a management fee if
it would cause the institution to become undercapitalized. Additionally, a bank
holding company controlling a significantly undercapitalized institution may not
make any capital distributions without the prior approval of the Federal Reserve
Board. Other supervisory actions may be taken against institutions that are
significantly undercapitalized, as well as undercapitalized institutions that
fail to submit an acceptable capital restoration plan as required by law or that
fail in any material respect to implement an accepted plan. See "Supervision and
Regulation--Prompt Corrective Action and Other Enforcement Mechanisms."
 
    The OCC has authority to prohibit the Banks from engaging in activities
that, in the OCC's opinion, constitute unsafe or unsound practices in conducting
its business. It is possible, depending upon the financial condition of the Bank
in question and other factors, that the OCC could assert that the payment of
dividends or other payments might, under some circumstances, be such an unsafe
or unsound practice. Further, the OCC and the Federal Reserve Board have
established guidelines with respect to the maintenance of appropriate levels of
capital by banks or bank holding companies under their jurisdiction. Compliance
with the standards set forth in such guidelines and the restrictions that are or
may be imposed under the prompt corrective action provisions of federal law
could limit the amount of dividends which the Banks or the Company may pay. See
"Item 1. Business--Supervision and Regulation--Prompt Corrective Regulatory
Action and Other Enforcement Mechanisms" and "--Capital Standards" for a
discussion of these additional restrictions on capital distributions.
 
    Frontier is currently prohibited by the terms of its Consent Order with the
OCC from paying any dividends without the prior consent of the OCC. See
"Supervision and Regulation--Potential and Existing Enforcement Actions." At
December 31, 1995, Ventura had $4.8 million in retained net profits available
for the payment of cash dividends.
 
    The Banks are subject to certain restrictions imposed by federal law on any
extensions of credit to, or the issuance of a guarantee or letter of credit on
behalf of, the Company or other affiliates, the purchase of or investments in
stock or other securities thereof, the taking of such securities as collateral
for loans and the purchase of assets of the Company or other affiliates. Such
restrictions prevent the Company and such other affiliates from borrowing from
the Banks unless the loans are secured by marketable obligations of designated
amounts. Further, such secured loans and investments by the Banks to or in the
Company or to or in any other affiliate is limited to 10% of each Banks' capital
and surplus (as defined by federal regulations) and such secured loans and
investments are limited, in the aggregate, to 20% of each Banks' capital and
surplus (as defined by federal regulations). Additional restrictions on
transactions with affiliates may be imposed on the Banks under the prompt
corrective action provisions of federal law. See "Item 1. Business--Supervision
and Regulation--Prompt Corrective Action and Other Enforcement Mechanisms."

    CAPITAL STANDARDS
 
    The Federal Reserve Board and the OCC have adopted risk-based minimum
capital guidelines intended to provide a measure of capital 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. Treasury securities, to 100% for assets with
relatively high credit risk, such as business loans.
 
    A banking organization's risk-based capital ratios are obtained by dividing
its qualifying capital by its total risk adjusted assets. The regulators measure
risk-adjusted assets, which includes 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 primarily of common stock,
retained earnings, noncumulative perpetual preferred stock (cumulative perpetual
preferred stock for bank holding companies) and minority interests in certain
subsidiaries, less most intangible assets. Tier 2 capital may consist of a
limited amount of the allowance for possible loan and lease losses, cumulative
preferred stock, long term preferred stock, eligible term subordinated debt and
certain other instruments with some characteristics of equity. The inclusion of
elements of Tier 2 capital is subject to certain other requirements and
limitations of the federal banking agencies. The federal banking agencies
require a minimum ratio of qualifying total capital to risk-adjusted assets of
8% and a minimum ratio of Tier 1 capital to risk-adjusted assets of 4%.
 
    In addition to the risk-based guidelines, federal banking regulators require
banking organizations to maintain a minimum amount of Tier 1 capital to total
assets, referred to as the leverage 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 is
3%. 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, or
4% to 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.
 
    In August 1995, the federal banking agencies adopted final regulations
specifying that the agencies will include, in their evaluations of a bank's
capital adequacy, an assessment of the exposure to declines in the economic
value of the bank's capital due to changes in interest rates. The final
regulations, however, do not include a measurement framework for assessing the
level of a bank's exposure to interest rate risk, which is the subject of a
proposed policy statement issued by the federal banking agencies concurrently
with the final regulations. The proposal would measure interest rate risk in
relation to the effect of a 200 basis point change in market interest rates on
the economic value of a bank. Banks with high levels of measured exposure or
weak management systems generally will be required to hold additional capital
for interest rate risk. The specific amount of capital that may be needed would
be determined on a case-by-case basis by the examiner and the appropriate
federal banking agency. Because this proposal has only recently been issued, the
Company currently is unable to predict the impact of the proposal on the Banks
if the policy statement is adopted as proposed.
 
    In January 1995, the federal banking agencies issued a final rule relating
to capital standards and the risks arising from the concentration of credit and
nontraditional activities. Institutions which have significant amounts of their
assets concentrated in high risk loans or nontraditional banking activities and
who fail to adequately manage these risks, will be required to set aside capital
in excess of the regulatory minimums. The federal banking agencies have not
imposed any quantitative assessment for determining when these risks are
significant, but have identified these issues as important factors they will
review in assessing an individual bank's capital adequacy.
 
                                      F-8
<PAGE>
    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.
The benchmark set forth by such policy statement is the sum of (a) assets
classified loss; (b) 50 percent of assets classified doubtful; (c) 15 percent of
assets classified substandard; and (d) estimated credit losses on other assets
over the upcoming 12 months.
 
    Federally supervised banks and savings associations are currently required
to report deferred tax assets in accordance with SFAS No. 109. The federal
banking agencies recently issued final rules, effective April 1, 1995, which
limit the amount of deferred tax assets that are allowable in computing an
institution's regulatory capital. The standard has been in effect on an interim
basis since March 1993. Deferred tax assets that can be realized for taxes paid
in prior carryback years and from future reversals of existing taxable temporary
differences are generally not limited. Deferred tax assets that can only be
realized through future taxable earnings are limited for regulatory capital
purposes to the lesser of (i) the amount that can be realized within one year of
the quarter-end report date, or (ii) 10% of Tier 1 Capital. The amount of any
deferred tax in excess of this limit would be excluded from Tier 1 Capital and
total assets for regulatory capital calculations.
 
    Future changes in 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 Banks to grow and could restrict the amount of
profits, if any, available for the payment of dividends.

    PROMPT CORRECTIVE ACTION AND OTHER ENFORCEMENT MECHANISMS
 
    Federal law 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.
 
                                      F-9

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

institution receives the highest rating from
its primary regulator)
 
"Critically undercapitalized"
- ---------------------------------------------
Tangible equity to total assets less than 2%.
</TABLE>
 
    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.
 
    The law prohibits insured depository institutions from paying management
fees to any controlling persons or, with certain limited exceptions, making
capital distributions if after such transaction the institution would be
undercapitalized. If an insured depository institution is undercapitalized, it
will be closely monitored by the appropriate federal banking agency, subject to
asset growth restrictions and required to obtain prior regulatory approval for
acquisitions, branching and engaging in new lines of business. Any
undercapitalized depository institution must submit an acceptable capital
restoration plan to the appropriate federal banking agency 45 days after
becoming undercapitalized. The appropriate federal banking agency cannot accept
a capital plan unless, among other things, it determines that the plan (i)
specifies the steps the institution will take to become adequately capitalized,
(ii) is based on realistic assumptions and (iii) is likely to succeed in
restoring the depository institution's capital. In addition, each company
controlling an undercapitalized depository institution must guarantee that the
institution will comply with the capital plan until the depository institution
has been adequately capitalized on an average basis during each of four
consecutive calendar quarters and must otherwise provide adequate assurances of
performance. The aggregate liability of such guarantee is limited to the lesser
of (a) an amount equal to 5% of the depository institution's total assets at the
time the institution became undercapitalized or (b) the amount which is
necessary to bring the institution into compliance with all capital standards
applicable to such institution as of the time the institution fails to comply
with its capital restoration plan. Finally, the appropriate federal banking
agency may impose any of the additional restrictions or sanctions that it may
impose on significantly undercapitalized institutions if it determines that such
action will further the purpose of the prompt corrective action provisions.
 
                                      F-10
<PAGE>
    An insured depository institution that is significantly undercapitalized, or
is undercapitalized and fails to submit, or in a material respect to implement,
an acceptable capital restoration plan, is subject to additional restrictions
and sanctions. These include, among other things: (i) a forced sale of voting
shares to raise capital or, if grounds exist for appointment of a receiver or
conservator, a forced merger; (ii) restrictions on transactions with affiliates;
(iii) further limitations on interest rates paid on deposits; (iv) further
restrictions on growth or required shrinkage; (v) modification or termination of
specified activities; (vi) replacement of directors or senior executive
officers; (vii) prohibitions on the receipt of deposits from correspondent
institutions; (viii) restrictions on capital distributions by the holding
companies of such institutions; (ix) required divestiture of subsidiaries by the
institution; or (x) other restrictions as determined by the appropriate federal
banking agency. Although the appropriate federal banking agency has discretion
to determine which of the foregoing restrictions or sanctions it will seek to
impose, it is required to force a sale of voting shares or merger, impose
restrictions on affiliate transactions and impose restrictions on rates paid on
deposits unless it determines that such actions would not further the purpose of
the prompt corrective action provisions. In addition, without the prior written
approval of the appropriate federal banking agency, a significantly
undercapitalized institution may not pay any bonus to its senior executive
officers or provide compensation to any of them at a rate that exceeds such
officer's average rate of base compensation during the 12 calendar months
preceding the month in which the institution became undercapitalized.
 
    Further restrictions and sanctions are required to be imposed on insured
depository institutions that are critically undercapitalized. For example, a
critically undercapitalized institution generally would be prohibited from
engaging in any material transaction other than in the ordinary course of
business without prior regulatory approval and could not, with certain
exceptions, make any payment of principal or interest on its subordinated debt
beginning 60 days after becoming critically undercapitalized. Most importantly,
however, except under limited circumstances, the appropriate federal banking
agency, not later than 90 days after an insured depository institution becomes
critically undercapitalized, is required to appoint a conservator or receiver
for the institution. The board of directors of an insured depository institution
would not be liable to the institution's shareholders or creditors for
consenting in good faith to the appointment of a receiver or conservator or to
an acquisition or merger as required by the regulator.
 
    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.
 
    SAFETY AND SOUNDNESS STANDARDS
 
    In July 1995, the federal banking agencies adopted final guidelines
establishing standards for safety and soundness, as required by FDICIA. The
guidelines set forth operational and managerial standards relating to internal
controls, information systems and internal audit systems, loan documentation,
credit underwriting, interest rate exposure, asset growth and compensation, fees
and benefits. Guidelines for asset quality and earnings standards will be
adopted in the future. The guidelines establish the safety and soundness
standards that the agencies will use to identify and address problems at insured
depository institutions before capital becomes impaired. If an institution fails
to comply with a safety and soundness standard, the appropriate federal banking
agency may require the institution to submit a compliance plan. Failure to
submit a compliance plan or to implement an accepted plan may result in
enforcement action.
 
                                      F-11
<PAGE>
    In December 1992, the federal banking agencies issued final regulations
prescribing uniform guidelines for real estate lending. The regulations, which
became effective on March 19, 1993, require insured depository institutions to
adopt written policies establishing standards, consistent with such guidelines,
for extensions of credit secured by real estate. The policies must address loan
portfolio management, underwriting standards and loan to value limits that do
not exceed the supervisory limits prescribed by the regulations.
 
    Appraisals for "real estate related financial transactions" must be
conducted by either state certified or state licensed appraisers for
transactions in excess of certain amounts. State certified appraisers are
required for all transactions with a transaction value of $1,000,000 or more;
for all nonresidential transactions valued at $250,000 or more; and for
"complex" 1-4 family residential properties of $250,000 or more. A state
licensed appraiser is required for all other appraisals. However, appraisals
performed in connection with "federally related transactions" must now comply
with the agencies' appraisal standards. Federally related transactions include
the sale, lease, purchase, investment in, or exchange of, real property or
interests in real property, the financing or refinancing of real property, and
the use of real property or interests in real property as security for a loan or
investment, including mortgage-backed securities.
 
    PREMIUMS FOR DEPOSIT INSURANCE
 
    Federal law has established several mechanisms to increase funds to protect
deposits insured by the Bank Insurance Fund ("BIF") administered by the FDIC.
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. The result of these provisions is that the assessment rate on
deposits of BIF members could increase in the future. The FDIC also has
authority to impose special assessments against insured deposits.
 
    The FDIC implemented a final risk-based assessment system, as required by
FDICIA, effective January 1, 1994, under which an institution's premium
assessment is based on the probability that the deposit insurance fund will
incur a loss with respect to the institution, the likely amount of any such
loss, and the revenue needs of the deposit insurance fund. As long as BIF's
reserve ratio is less than a specified "designated reserve ratio," 1.25%, the
total amount raised from BIF members by the risk-based assessment system may not
be less than the amount that would be raised if the assessment rate for all BIF
members were .023% of deposits. On August 8, 1995, the FDIC announced that the
designated reserve ratio had been achieved and, accordingly, issued final
regulations adopting an assessment rate schedule for BIF members of 4 to 31
basis points effective on June 1, 1995. On November 14, 1995, the FDIC further
reduced deposit insurance premiums to a range of 0 to 27 basis points effective
for the semi-annual period beginning January 1, 1996.
 
    Under the risk-based assessment system, a BIF member institution such as the
Banks is categorized into one of three capital categories (well capitalized,
adequately capitalized, and undercapitalized) and one of three categories based
on supervisory evaluations by its primary federal regulator (in the Bank's case,
the FDIC). The three supervisory categories are: financially sound with only a
few minor weaknesses (Group A), demonstrates weaknesses that could result in
significant deterioration (Group B), and poses a substantial probability of loss
(Group C). The capital ratios used by the FDIC to define well-capitalized,
adequately capitalized and undercapitalized are the same in the FDIC's prompt
corrective action regulations. The BIF assessment rates are summarized below;
assessment figures are expressed in terms of cents per $100 in deposits.

* Subject to a statutory minimum assessment of $1,000 per semi-annual period
  (which also applies to all other assessment risk classifications).
 
    A number of proposals have recently been introduced in Congress to address
the disparity in bank and thrift deposit insurance premiums. On September 19,
1995, legislation was introduced and referred to the House Banking Committee
that would, among other things: (i) impose a requirement on all SAIF member
institutions to fully recapitalize the SAIF by paying a one-time special
assessment of approximately 85 basis points on all assessable deposits as of
March 31, 1995, which assessment would be due as of January 1, 1996; (ii) spread
the responsibility for FICO interest payments across all FDIC-insured
institutions on a pro-rata basis, subject to certain exceptions; (iii) require
that deposit insurance premium assessment rates applicable to SAIF member
institutions be no less than deposit insurance premium assessment rates
applicable to BIF member institutions; (iv) provide for a merger of the BIF and
the SAIF as of January 1, 1998; (v) require savings associations to convert to
state or national bank charters by January 1, 1998; (vi) require savings
associations to divest any activities not permissible for commercial banks
within five years; (vii) eliminate the bad-debt reserve deduction for savings
associations, although savings associations would not be required to recapture
into income their accumulated bad-debt reserves; (viii) provide for the
conversion of savings and loan holding companies into bank holding companies as
of January 1, 1998, although unitary savings and loan holding companies
authorized to engage in activities as of September 13, 1995 would have such
authority grandfathered (subject to certain limitations); and (ix) abolish the
OTS and transfer the OTS' regulatory authority to the other federal banking
agencies. The legislation would also provide that any savings association that
would become undercapitalized under the prompt corrective action regulations as
a result of the special deposit premium assessment could be exempted from
payment of the assessment, provided that the institution would continue to be
subject to the payment of semiannual assessments under the current rate schedule
following the recapitalization of the SAIF. The legislation was considered and
passed by the House Banking Committee's Subcommittee on Financial Institutions
on September 27, 1995, and has not yet been acted on by the full House Banking
Committee.
 
    On September 20, 1995, similar legislation was introduced in the Senate,
although the Senate bill does not include a comprehensive approach for merging
the savings association and commercial bank charters. The Senate bill remains
pending before the Senate Banking Committee.
 
                                      F-13
<PAGE>
    The future of both these bills is linked with that of pending budget
reconciliation legislation since some of the major features of the bills are
included in the Seven-Year Balanced Budget Reconciliation Act. The budget bill,
which was passed by both the House and Senate on November 17, 1995 and vetoed by
the President on December 6, 1995, would: (i) recapitalize the SAIF through a
special assessment of between 70 and 80 basis points on deposits held by
institutions as of March 31, 1995; (ii) provide an exemption to this rule for
weak institutions, and a 20% reduction in the SAIF-assessable deposits of
so-called "Oakar banks;" (iii) expand the assessment base for FICO payments to
include all FDIC-insured institutions; (iv) merge the BIF and SAIF on January 1,
1998, only if no insured depository institution is a savings association on that
date; (v) establish a special reserve for the SAIF on January 1, 1998; and (vi)
prohibit the FDIC from setting semiannual assessments in excess of the amount
needed to maintain the reserve ratio of any fund at the designated reserve
ratio. The bill does not include a provision to merge the charters of savings
associations and commercial banks.
 
    In light of ongoing debate over the content and fate of the budget bill, the
different proposals currently under consideration and the uncertainty of the
Congressional budget and legislative processes in general, management cannot
predict whether any or all of the proposed legislation will be passed, or in
what form. Accordingly, the effect of any such legislation on the Banks cannot
be determined.
 
    INTERSTATE BANKING AND BRANCHING
 
    In September 1994, the Riegle-Neal Interstate Banking and Branching
Efficiency Act of 1994 (the "Interstate Act") became law. Under the Interstate
Act, beginning one year after the date of enactment, a bank holding company that
is adequately capitalized and managed may obtain approval under the BHC Act to
acquire an existing bank located in another state without regard to state law. A
bank holding company would not be permitted to make such an acquisition if, upon
consummation, it would control (a) more than 10% of the total amount of deposits
of insured depository institutions in the United States or (b) 30% or more of
the deposits in the state in which the bank is located. A state may limit the
percentage of total deposits that may be held in that state by any one bank or
bank holding company if application of such limitation does not discriminate
against out-of-state banks. An out-of-state bank holding company may not acquire
a state bank in existence for less than a minimum length of time that may be
prescribed by state law except that a state may not impose more than a five year
existence requirement.
 
    The Interstate Act also permits, beginning June 1, 1997, mergers of insured
banks located in different states and conversion of the branches of the acquired
bank into branches of the resulting bank. Each state may permit such
combinations earlier than June 1, 1997, and may adopt legislation to prohibit
interstate mergers after that date in that state or in other states by that
state's banks. The same concentration limits discussed in the preceding
paragraph apply. The Interstate Act also permits a national or state bank to
establish branches in a state other than its home state if permitted by the laws
of that state, subject to the same requirements and conditions as for a merger
transaction.
 
    In October 1995, California adopted "opt in" legislation under the
Interstate Act that permits out-of-state banks to acquire California banks that
satisfy a five-year minimum age requirement (subject to exceptions for
supervisory transactions) by means of merger or purchases of assets, although
entry through acquisition of individual branches of California institutions and
de novo branching into California are not permitted. The Interstate Act and the
California branching statute will likely increase competition from out-of-state
banks in the markets in which the Company operates, although it is difficult to
assess the impact that such increased competition may have on the Company's
operations.
 
    COMMUNITY REINVESTMENT ACT AND FAIR LENDING DEVELOPMENTS
 
    The Banks are subject to certain fair lending requirements and reporting
obligations involving home mortgage lending operations and Community
Reinvestment Act ("CRA") activities. The CRA generally
 
                                      F-14
<PAGE>
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 substantial 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. The OCC has rated
Ventura "satisfactory" and Frontier "needs to improve" in complying with their
respective CRA obligations.
 
    In May 1995, the federal banking agencies issued final regulations which
change the manner in which they measure a bank's compliance with its CRA
obligations. The final regulations adopt a performance-based evaluation system
which bases CRA ratings on an institution's actual lending service and
investment performance rather than the extent to which the institution conducts
needs assessments, documents community outreach or complies with other
procedural requirements. In March 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.
 
    POTENTIAL AND EXISTING ENFORCEMENT ACTIONS
 
    Commercial banking organizations, such as the Banks, and their
institution-affiliated parties, which include the Company, are subject to
potential enforcement actions by the Federal Reserve Board, the FDIC and the OCC
for any 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 the Banks), 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 imposition of restrictions and
sanctions under the prompt corrective action provisions of the FDIC Improvement
Act. 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.
 
    Following supervisory examinations of Ventura conducted as of June 30, 1992
and Frontier as of July 30, 1992, Ventura entered into a Formal Agreement with
the OCC on March 19, 1993 and Frontier entered into a Consent Order with the OCC
on March 29, 1993. The Consent Order replaced the 1992 MOU previously entered
into between the OCC and Frontier. Based upon an examination of Ventura
completed during the fourth quarter of 1995, the OCC terminated Ventura's Formal
Agreement as of November 30, 1995.
 
    The significant requirements of Frontier's Consent Order include conducting
a program to evaluate and improve board supervision and management, developing a
program designed to improve the lending staff and loan administration, obtaining
current credit information on any loans lacking such information, reviewing and
revising loan policies, establishing an independent loan review program
including periodic reports to the Board, developing and implementing a program
to collect or strengthen criticized assets, reviewing and maintaining an
adequate loan loss reserve, developing a new long range strategic plan and
annual budget, developing a three-year capital plan, developing and revising
liquidity and funds management policy, correcting violations of law cited by the
OCC and obtaining approval from the OCC to declare or pay a dividend. In
addition, the Consent Order requires that Frontier maintain as of May 31, 1993
and beyond a Tier 1 risk based capital ratio of 9.50% and a leverage capital
ratio of 7.00%. At December 31, 1995, Frontier's Tier 1 risk based capital ratio
was 13.78% and its leverage capital ratio was 9.80%. The Consent Order also
requires Frontier to retain a new president and to continue to develop a program
of asset diversification.
 
                                      F-15
<PAGE>
    The Company entered into the MOU with the Federal Reserve Bank of San
Francisco (the "Reserve Bank") acting under delegated authority from the Federal
Reserve Board on March 19, 1994. The significant requirements of the MOU include
submitting a program to improve the financial condition of the Banks, evaluate
and improve board supervision and management, exit the commercial paper market,
comply with Federal Reserve Board policy regarding management or service fees
assessed by the Company and paid by the Banks and implement steps to improve the
effectiveness of the audit and credit review functions. The MOU further
restricts the Company from declaring or paying a dividend, incurring any debt,
adding or replacing a director or senior executive or repurchasing Company stock
without notice to and nondisapproval of the Reserve Bank. The MOU also requires
the Company's Board of Directors to establish a committee to monitor compliance
with the MOU and ensure that quarterly written progress reports detailing the
form and manner of all actions taken to attain compliance with the MOU are
submitted.
 
    Management believes Frontier and the Company are in full compliance with all
of the items required under the Consent Order and MOU, respectively.

(1) Includes $2.24 million of SBA loans held for sale at December 31, 1995.
 
    NONPERFORMING ASSETS:  Nonperforming loans are those on which the borrower
fails to perform under the original terms of the obligation. The Company's
nonperforming loans fall within three categories: loans past due 90 days and
still accruing, loans on nonaccrual status and restructured loans. The coverage
ratio, or the ratio of loan loss reserves to nonperforming loans, was 121.62%
and 103.98%, at December 31, 1995, and 1994, respectively. Loans past due 90
days or more and still accruing totaled $101 thousand and $331 thousand at
December 31, 1995, and 1994, respectively. Total nonperforming loans as a
percent of total loans outstanding were 2.81% and 4.73% at December 31, 1995 and
1994, respectively. The decrease in nonaccrual loans was primarily attributable
to the collection of the same and the overall improvement in the credit quality
of the loan portfolio.
 
    Loans are automatically placed on nonaccrual status when principal or
interest payments are past due greater than 90 days. If a loan is an SBA
guaranteed loan and a deferral period has been negotiated or if the loan is in
the process of imminent collection in the normal course of business, the Company
may remove the loan from nonaccrual status and continue to accrue interest.
Loans are placed on nonaccrual status earlier, if there is doubt as to the
collectibility of any amounts due according to the contractual terms of the loan
agreement. At December 31, 1995, loans totaling $4.3 million were on nonaccrual
status, compared to $7.6 million at December 31, 1994.
 
    As of December 31, 1995, the Company had $3.643 million in restructured
loans, of which $3.326 million were performing in accordance with their
restructured terms for a specified period of time, typically at least six
months. The remaining balance is included within loans on nonaccrual status. As
of December 31, 1994, the Company had $1.968 million in restructured loans, of
which $1.966 million were performing in accordance with their restructured
terms.
 
    ALLOCATION FOR ALLOWANCE FOR LOAN LOSSES:  Over the five year period ended
December 31, 1995, the allocation of the allowance for loan losses for
commercial, financial and agricultural loans increased steadily to correspond
with increases in the total volume of loans and the level of loan losses in this
category. The Company's current practice is to make specific allocations to
large loans and unspecified
 
                                      F-18
<PAGE>
allocations to each loan category based on management's risk assessment. While
management has allocated reserves to various portfolio categories, the reserve
is general in nature and is available for the loan portfolio The following table
sets forth the allocation of the allowance for loan losses by loan category as
of the dates indicated.

    POTENTIAL PROBLEM LOANS:  The level of nonperforming assets will depend to a
great extent on the future economic environment. Currently, management of the
Company has identified $9.3 million in potential problem loans at December 31,
1995, in addition to its nonperforming assets, performing restructured loans and
accruing loans 90 days or more past due, as to which it has serious doubts as to
the ability of the borrowers to comply with the present repayment terms and
which may become nonperforming assets, based on known information about possible
credit problems of the borrower.
 
    FOREGONE INTEREST INCOME:  If nonaccrual, past due and restructured loans
had been current and performing according to original terms, gross interest
income for the years ended December 31, 1995, 1994, 1993, 1992 and 1991 would
have increased by $1.3 million, $1.6 million, $2.2 million, $728 thousand and
$429 thousand, respectively. The following summarizes foregone interest income
for 1995:

DEPOSITS
 
    The Company competes for deposits principally by providing quality customer
service at the Banks' branch offices. In order to stabilize its funding sources,
the Company has taken action to reduce title and escrow demand deposits and
institutional certificates of deposits as a percentage of total deposits. The
Banks are prohibited from purchasing brokered deposits by virtue of their
regulatory agreements with the OCC. See "Supervision and Regulation".

ITEM 2:  PROPERTIES
 
    Since October 1987, Company headquarters have been located at 500 Esplanade
Drive in Oxnard, California. The Company and Ventura's main offices share 31,097
square feet of leased space. The lease which expires in 2002, requires the
Company to pay for any allocated property tax or utility cost increases and to
adjust the monthly rent annually, based on consumer price index changes. The
Company does not have an option to renew this lease. The Company subleased 9,335
square feet of office space in December 1994, from which the Company anticipates
annual cost savings of approximately $134,000.
 
    Ventura leases a 3,100 square foot building at 4730 Telephone Road in
Ventura for its Ventura branch office under a lease expiring November 1996.
Ventura does not have an option to renew this lease. The Company anticipates
that it will attempt to negotiate a renewal of this lease or look for another
suitable location in the third quarter of 1996.
 
    Ventura also leases 6,640 square feet at 502 Las Posas Road, Camarillo and
4,000 square feet at 2655 Townsgate Road in Westlake Village for its Camarillo
and Westlake Village branch offices, respectively. The Camarillo lease expires
in June of 1997, with one ten year and two five year options to renew. The
Westlake Village lease expires in 2005, with one five year option to renew.
Ventura pays its pro rata share of utilities, taxes, common area maintenance and
insurance on all branch locations. In addition to annual adjustments tied to the
consumer price index, Ventura pays $12,000 annually on the Westlake Village
property in lieu of an option to construct an additional 7,000 square foot
building.
 
    Ventura's Central Operations is housed in 8,105 square feet at 2125 Knoll
Drive in Ventura. The lease expires on March 31, 2000. The lease provides for
annual adjustments of the rent. The Company has the option of terminating the
lease without penalty during the final year.
 
                                      F-21
<PAGE>
    Frontier's main office occupies 17,588 square feet at One Centerpointe Drive
in La Palma, California and Frontier has subsequently subleased an additional
8,559 square feet. Frontier leased an additional 1,668 square feet at One
Centerpointe Drive in La Palma under an amendment to the original lease. The
lease for the main office expires in December 2006 and the lease for the
additional space expires in July 1998. Frontier does not have an option to renew
these leases.
 
    Frontier purchased a 9,007 square foot building located at 131 West Anaheim
Street in Wilmington for its South Bay branch office during June of 1995.
Frontier purchased the building and lot from the FDIC as a receiver for Maritime
Bank for $265,000 cash. Frontier terminated the month to month lease on its
previous Wilmington branch location and began operating at the current branch
location in September 1995.
 
    The Company believes its present facilities are adequate for its present
needs and anticipated future growth. The Company believes that, if necessary, it
could secure suitable alternative facilities on similar terms without adversely
affecting operations.
 
ITEM 3:  LEGAL PROCEEDINGS
 
    There are no material legal proceedings pending other than ordinary routine
litigation incidental to the business of the Company to which the Company or its
subsidiaries is a party or of which any of their property is a subject, except
as described below.
 
SHARON TILLIS, KAREN TILLIS, ET AL V. BANKAMERICA CORPORATION, ET AL.
 
    On January 26 1993, plaintiffs filed a class action lawsuit in Los Angeles
County Superior Court, Case No. BC 073448, against Wilshire Computer College
("WCC"), its proprietor Peter Chung, Bank of America, N.T. & S.A. ("Bank of
America") and the California Student Aid Commission ("CSAC"). The Complaint was
subsequently amended to add Ventura, Marine Midland Bank, N.A. ("Marine
Midland") and Educational Funding Services, Inc. ("EFSI"). (Bank of America,
Marine Midland, EFSI and Ventura are collectively referred to as the "Bank
Defendants"). This action arises out of loans made to students of WCC, which
plaintiffs contend were made to induce them to enroll at WCC. VCNB appears to
have made $4.2 million in loans to students at WCC who are sought to be included
in the class. CSAC and the Bank Defendants filed a joint demurrer and motion to
strike portions of the First Amended Complaint, which was sustained on November
17, 1993, eliminating several theories of liability against the Bank Defendants.
 
    Plaintiffs filed a Second Amended Complaint, alleging the following seven
causes of action against the Bank Defendants: (1) violations of Business and
Professions Code (S)17500 regarding allegations of untrue or misleading
statements to prospective students to induce them to enroll at WCC; (2)
violations of the Unruh Act, Civil Code (S)1801 regarding allegations that the
student loan agreements constituted retail installment sales contracts; (3)
violations of Business and Professions Code (S)17200 regarding allegations that
defendants engaged in unfair business practices, including unfair advertising,
acting without permits and making false representations to students and
agencies; (4) fraud, misrepresentation and negligent misrepresentation regarding
allegations that employees and representatives of WCC made misrepresentations to
students to induce them to enroll at the WCC; (5) breach of contract, breach of
the implied covenant of good faith based on the contracts entered into between
plaintiffs and Bank Defendants; (6) rescission and restitution based on the
contracts entered into between plaintiffs and Bank Defendants; and (7) secondary
theories of liability based on causes (1), (3) and (4) regarding allegations of
agency, joint venture, aiding and abetting and close connection.
 
    CSAC and the Bank Defendants filed a joint demurrer to all causes of action
in the Second Amended Complaint which was sustained without leave to amend as to
the Bank Defendants and with leave to amend as to CSAC. Plaintiffs did not amend
their Second Amended Complaint, however, and the court issued an Order and
Judgment of Dismissal of all defendants on October 12, 1994. Notice of Entry of
Judgment in this matter was served on October 25, 1994.
 
                                      F-22
<PAGE>
    On December 7, 1994, plaintiffs filed a Notice of Appeal with the Court of
Appeal of the State of California and briefs on appeal have been filed. Oral
arguments are scheduled for December 1996. Bank of America reached a settlement
with plaintiffs and plaintiffs and the other Bank Defendants have engaged in
settlement negotiations but, to date, no settlement has been reached. Based upon
the advice of counsel, should the appellate court find reason to reverse the
demurrer, management is currently unable to estimate the likelihood of an
unfavorable outcome or the amount or range of potential loss.

    Parent has never paid a cash dividend on the Common Stock and there can be
no assurance that Parent will generate earnings in the future which would permit
the declaration of dividends. Parent is prohibited by the terms of the MOU from
declaring or paying a dividend without fifteen days prior notice to the Reserve
Bank, which may prohibit the payment of dividends.
 
    In addition, the source of any such dividends is likely to be dividends from
Ventura or Frontier. Frontier is also limited in the amount of dividends which
it may distribute according to the terms of the Consent Order. Pursuant to the
Consent Order, the Board of Directors may declare or pay dividends only: (i)
when Frontier is in compliance with 12 U.S.C. sections 56, 60, and 1831o(d)(1);
(ii) when Frontier is in compliance with the capital program developed pursuant
to the Consent Order; (iii) when such dividend payment is consistent with the
capital levels specified in paragraph (1) of the Consent Order; and (iv) with
prior written approval of the District Administrator of the OCC, pursuant to the
Consent Order. See "Supervision and Regulation--Restrictions on Transfers of
Funds to Parent by the Banks." Furthermore, it is anticipated that for the
foreseeable future any earnings which may be generated will be retained for the
purpose of increasing the Company's capital and reserves in order to facilitate
growth.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    The following presents management's discussion and analysis of the
consolidated financial condition and operating results of the Company as of and
for the years ended December 31, 1995, 1994, and 1993. The discussion should be
read in conjunction with the Company's audited Consolidated Financial Statements
and Notes.
 
OVERVIEW
 
    The Company had net income of $3.8 million or $0.48 per share for the year
ended December 31, 1995, compared to a net loss of $262 thousand or $0.04 per
share for the year ended December 31, 1994. The significant improvement over
1994 was a result of a decrease in the provision for loan losses, reduced
noninterest expenses and the release of the valuation reserve previously held
against deferred tax assets, offset by lower net interest income and noninterest
income. The net loss incurred in 1994 was partially offset by gains on the sale
of mortgage servicing rights and the merchant card portfolio totaling $1.4
million and $174 thousand, respectively. The decrease in the provision for loan
losses was a result of decreases in gross loans and classified loan balances of
$10.2 million and $15.3 million, respectively, from 1994 to 1995. The decrease
in noninterest expense results from lower holding costs and reduced fair value
adjustments on the sale of Real Estate Owned ("REO") properties, lower legal and
consulting fees, reduced appraisal fees and mortgage servicing expenses, and
lower FDIC/Comptroller assessments. Current year net income includes the release
of the valuation reserve previously held against the deferred tax assets, which
resulted in a net tax benefit of $2.4 million.
 
    Total assets increased 3.9% from December 31, 1994, to December 31, 1995, as
a result of increased capital from the common stock rights offering completed
during the second quarter of 1995 and funding from the Company's profitability.
 
    The Company had a net loss of $262 thousand for the year ended December 31,
1994, compared to a net loss of $12.1 million for the year ended December 31,
1993. The improvement over 1993 was due to a significant decrease in the
provision for loan losses, reduced noninterest expense and improved net interest
income in 1994.
 
    Total assets decreased 24.3% from December 31, 1993, to December 31, 1994.
During 1994, the balance sheet was reduced for liquidity purposes, as well as to
achieve compliance with the capital requirements of the Banks' regulatory
agreements.
 
FINANCIAL CONDITION
 
    Total assets at December 31, 1995, increased $10.0 million, or 3.9% to
$267.8 million, from $257.8 million at December 31, 1994. Most of the increase
is in cash and overnight Federal funds investments offset by lower year end
balances for investment securities and loans. The Company raised gross proceeds
of $6.5 million in capital during 1995 through the common stock rights offering.
Net loans and leases decreased $7.3 million or 4.6% from year end 1994,
primarily due to the planned payoff of loans and the reduction in classified
loans. The reduction in classified loans is due to loan payoffs and from
transfers to OREO of $4.4 million, of which $4.1 million were subsequently sold
prior to year end.
 
    Total assets decreased $83.0 million from $340.6 million at December 31,
1993, to $257.8 million at December 31, 1994. This decrease resulted from
management's efforts to reduce the loan to deposit ratio, increase capital
ratios and improve liquidity by tightening underwriting criteria, selling
nonperforming loans at a discount and marketing loan participations.
Additionally, to reduce volatility in the Banks' deposit bases, the Company
allowed significant runoff of title and escrow demand deposits and institutional
certificates of deposit during 1994.

    CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents consist of cash on hand, deposits at correspondent
banks and interest-bearing amounts due from banks. The Company maintains
balances at correspondent banks adequate to cover daily inclearings and other
charges. In accordance with Federal regulations, average reserve balances of
$1.7 million were maintained in the form of deposits with the Federal Reserve
Bank for the year ended December 31, 1995.
 
    Cash and cash equivalents increased $8.5 million from $11.4 million at year
end 1994 to $19.9 million at December 31, 1995. Most of the increase resulted
from the increase in the compensating balance requirements with correspondent
banks due to volume increases. Cash and cash equivalents decreased $4.5 million
from $15.9 million at December 31, 1993 to $11.4 million at December 31, 1994.
 
    FEDERAL FUNDS SOLD
 
    The Company invests or sells its excess cash balances in overnight Federal
funds. federal funds sold at December 31, 1995, were $47.5 million as compared
to $27.0 million at December 31, 1994. During 1995, the yield curve inverted;
overnight federal funds yields were the equivalent of US Treasury securities
with 5 or 7 year maturities. Management decided to maintain high levels of
overnight federal funds investments to increase net interest income and margins
during this yield curve inversion.
 
    Federal funds sold at December 31, 1994, increased $9.0 million from $18.0
million at December 31, 1993, due to improvements in the Company's liquidity
during 1994.
 
    INVESTMENT SECURITIES
 
    Investment securities at December 31, 1995, were $36.6 million and did not
include any securities classified at held-to-maturity. In November 1995, the
Financial Accounting Standards Board ("FASB") issued a "Guide to Implementation
of Statement 115 on Accounting for Certain Investments in Debt and Equity
Securities: Questions and Answers" (the "Guide"). The Guide allowed for a one
time reassessment of the classification of all securities and, in connection
with such reassessment, permitted the reclassification of securities from the
held-to-maturity classification to the available-for-sale classification as of a
single date no later than December 31, 1995, without calling into question
management's intent to hold to maturity the remaining securities classified as
held-to-maturity. On December 21, 1995, the Company transferred its entire
portfolio of held-to-maturity securities with an amortized cost of $20.2 million
to the available-for-sale classification to allow for greater flexibility in the
Company's investment portfolio. The transfer resulted in an unrealized gain of
$186 thousand, net of the unamortized portion of unrealized loss recorded when
certain securities were transferred from the available-for-sale to
held-to-maturity classification during 1994. The unrealized gain will remain as
a separate component of shareholders' equity until the securities are sold or
mature.
 
    Investment securities consist of U.S. Government, U.S. Government Agency and
mortgage-backed securities. Mortgage-backed securities consisted entirely of
Federal Home Loan Mortgage Corporation pass through certificates at December 31,
1995. The Company did not have structured notes, CMOs or other derivative
products in the portfolios at December 31, 1995 or 1994.
 
    Investment securities decreased $14.0 million to $36.6 million at December
31, 1995, from $50.6 million at December 31, 1994. Available-for-sale securities
were sold at a slight net gain during 1995. The proceeds from sales were
reinvested in overnight federal funds to take advantage of the inverted yield
curve. At December 31, 1995, the average life of the mortgage-backed securities
was approximately 3 years; the average maturities of mortgage-backed securities
was approximately 9 years.
 
    The net unrealized loss on available-for-sale securities decreased $563
thousand to $615 thousand from $1.2 million at December 31, 1995, and 1994,
respectively. In accordance with SFAS No. 115, the net unrealized gain or loss
from increases or decreases in the fair value of available-for-sale securities
is
 
                                      F-31
<PAGE>
reported as a separate component of shareholders' equity, net of related income
tax effects. The decrease in the unrealized loss from 1994, was due to an
increase in the fair values of the available-for-sale securities and a net gain
of $186 thousand upon transfer from the held-to-maturity portfolio.
 
    On December 31, 1993, the Company adopted SFAS No. 115, "Accounting for
Certain Investments in Debt and Equity Securities." In connection with the
adoption of SFAS No. 115, the Company classified all of its investment
securities as available for sale and recorded unrealized loss of $122 thousand,
net of tax effect. During 1994, the Company purchased securities which were
classified as either available-for-sale or held-to-maturity at the time of
purchase, based on management's intent and ability to hold certain investments
to maturity. The Company transferred mortgage backed securities with unrealized
losses of $472 thousand from available-for-sale to held-to-maturity during 1994
due to a change in intent to hold the securities to maturity. Certain of these
securities were transferred back to the available-for-sale portfolio during 1995
in accordance with the one-time reclassification of held-to-maturity securities
permitted by the Guide.
 
    As of December 31, 1994, approximately $18.8 million of securities were
classified at their amortized cost as held-to-maturity. Most of this balance was
comprised of mortgage-backed securities that were transferred from the
available-for-sale portfolio. Unrealized losses of $433 thousand previously
recorded for these securities were included in shareholders' equity at December
31, 1994.
 
    At December 31, 1994, the average life of mortgage-backed securities was
approximately 3.5 years; the average maturities of mortgage-backed securities
was approximately 10 years.
 
    LOANS
 
    The Company engages in loans to small to medium-sized businesses in its
service areas. The Company also originates and sells Small Business
Administration ("SBA") loans. The interest rates charged for the loans made by
the Company vary with the degree of risk, the size and maturity of the loan,
whether the loan has a fixed or variable rate, the borrowers' depository
relationship with the Company, and prevailing market interest rates. The Company
is primarily a commercial lender, and most of its loans are floating rate loans
tied to prime.
 
    The balance of loans outstanding at year end decreased for the second
straight year from $167.9 million to $157.8 million at December 31, 1995, and
1994, respectively. Approximately $3.3 million of the decrease was due to the
repayment of nonaccrual loans, which decreased to $4.3 million, down from $7.6
million at December 31, 1995, and 1994, respectively. A discussion of the
activity in the Company's loan portfolios follows.
 
    COMMERCIAL, FINANCIAL, AND AGRICULTURAL
 
    This category includes secured commercial loans, SBA loans, asset based
loans, loans to developers, unsecured commercial loans, and medium-term real
estate loans. Commercial, financial and agricultural loans increased slightly to
$142.4 million from $138.2 million at December 31, 1995, and 1994, respectively.
 
    COMMERCIAL LOANS
 
    This category constitutes the core of the Company's business. Included in
this category are commercial loans made to medium-sized businesses which include
revolving lines of credit, term loans for working capital or short-term
commercial needs, and medium-term commercial real estate loans. Management will
generally require the borrower to pledge certain of the borrower's assets to
support the credits with terms limited to one year or less. Medium-term
commercial real estate loans are those credits made for the financing of a
commercial or industrial building where the property has income derived from
tenants ("investment properties") or used by the owner for business purposes
("owner-user properties").
 
                                      F-32
<PAGE>
    Commercial loans decreased $18.8 million to $112.3 million as of December
31, 1995. Most of this decrease was in medium-term commercial real estate loans,
particularly those loans secured by investment properties, that was partially
offset by increased balances for non-real estate secured commercial loans. To
the extent that medium-term commercial real estate loans are made, they are
generally limited to owner-user properties or for companies that also have other
banking relationships with the Company. Management believes these medium-term
commercial real estate loans have less risk as the Company has a broader
knowledge and better control over the overall borrowing relationship.
 
    As of December 31, 1994, commercial loans decreased $59.2 million to $167.9
million from $227.1 million as of December 31, 1993. The Company sold
approximately $25 million of loans in a bulk sale during May 1994. Another
decrease of approximately $10 million was due to loan workouts and collections,
and finally, management believes that additional prepayments of approximately $7
million were a result of the market conditions at that time.
 
    SBA LOANS
 
    Through its SBA Division, Frontier offers loans for equipment, working
capital, debt repayment and construction, and acquisition of owner-user
commercial real estate. Frontier originates loans under both the 7(a) and 504
loan programs, with a particular emphasis on the 7(a) program. Frontier has been
authorized by the SBA to make 7(a) loans since 1983. Frontier has been
designated as a PLP lender in the 7(a) program by the SBA. This designation,
which has been granted to fewer than 1% of all SBA lenders nationwide, allows
Frontier to directly approve the guaranty request on behalf of SBA, and requires
Frontier send to SBA only a streamlined informational loan file. The guaranteed
portions of SBA 7(a) loans are normally sold by Frontier to secondary market
investors at a premium. Frontier continues to service the whole loan, and is
required by the SBA to maintain a minimum 1% servicing spread on the sold
portion.
 
    The guaranteed portion of SBA loans originated for sale is reported at the
lower of cost or fair value in the consolidated balance sheets. SBA loans
acquired for investment are reported at amortized cost in the consolidated
balance sheets.
 
    SBA loans increased $17.3 million from $12.8 million to $30.1 million at
December 31, 1995, and 1994, respectively. Most of this increase resulted from
the purchase of approximately $11 million of SBA loans by Ventura. The rest of
the increase was due to the Frontier SBA loan program.
 
    REAL ESTATE--MORTGAGE LOANS
 
    Included in this category are loans for single family residences (conforming
loans) and home equity loans. The Company sold its residential mortgage
origination operations in 1994, and no longer originates residential mortgages
for the acquisition of homes, unless it is for the sole purpose of accommodating
an existing business borrower. The $4.1 million decrease in mortgage loans
during 1995 was due to the programmed reduction in mortgage loans and reduced
mortgage activity after the Company sold its mortgage operations in 1994. From
December 31, 1993 to December 31, 1994, mortgage loans decreased $31.2 million,
which reflects the 1994 sale.
 
    REAL ESTATE--CONSTRUCTION LOANS
 
    Ventura provides real estate construction loans for custom residential and
residential tract development projects, as well as commercial developments.
Management has implemented a policy to maintain real estate construction loans
at 10% to 15% of the total portfolio. Real estate construction loans decreased
from $7.7 million at December 31, 1994, to $1.5 million at December 31, 1995.
The decreases in real estate construction loans reflects the absence of demand
for new construction in the Banks' service areas during the past two years.
 
                                      F-33
<PAGE>
    INSTALLMENT LOANS
 
    Installment loans consist mainly of fully amortizing credits for the
purchase of capital goods and consumer purchases. Installment loans decreased
$2.9 million from $9.9 million at December 31, 1994, to $7.0 million at December
31, 1995. The decrease in installment loans principally resulted from the sale
of the Company's merchant credit card operations in 1994.
 
ASSET QUALITY
 
    LOAN LOSS RESERVES AND NONPERFORMING LOANS
 
    The Company maintains a loan loss reserve which it considers adequate to
cover the risk of losses in the loan and lease portfolio. The charge to expense
is based on management's evaluation of the quality of the loan and lease
portfolio, the level of classified loans and leases, total outstanding loans and
leases, losses previously charged against the reserve, and current and
anticipated economic conditions. Management also considers certain elements in
the portfolio and the grading systems used to measure the quality of the
portfolio. These factors include industry concentrations and collateral
concentrations. In response to the recession in Southern California and the
decline in real estate values, the Company assessed the value of collateral for
loans, particularly those secured by real estate. If during this process a
shortfall ensued, the Company then recorded a charge-off or provided a specific
reserve to reflect the current market value of the loan. The Company expanded
the Loan Administration and Special Assets Departments to improve overall asset
quality through problem loan management and risk and collateral value
identification. In addition, regulatory agencies, as an integral part of their
examination process, periodically review the adequacy of the Company's loan loss
reserve. Such agencies may require the Company to recognize additions to the
loan loss reserve based upon their judgment of the information available to them
at the time of their examination.
 
    The following table sets forth nonaccrual loans, loans which were delinquent
for 90 days or more but still accruing, loan that are accounted for as "troubled
debt restructurings" ("TDRs"), real estate owned ("REO") and potential problem
loans at the dates indicated.

(1) Does not include loans which have been restructured and which were
    previously on nonaccrual status but have been performing in accordance with
    their restructured terms for some minimum period of time, typically at least
    six months. At December 31, 1995 and 1994, the Company had such loans in the
    amounts of $3.3 million and $2.0 million, respectively.
 
    PREMISES AND EQUIPMENT, NET
 
    Fixed assets, net of depreciation, increased from $1.9 million at December
31, 1994 to $2.4 million at December 31, 1995, due to the purchase of the
Wilmington branch and related building improvements that were made to the
facility, net of an inventory adjustment of $115 thousand. Fixed assets, net of
 
                                      F-34
<PAGE>
depreciation, increased from $1.7 million at December 31, 1993 to $1.9 million
at December 31, 1994. The fluctuations since 1993 have resulted from accumulated
depreciation charges and the acceleration of depreciation related to data
processing equipment and leaseholds, offset by the purchase of and capitalized
costs related to the Wilmington branch during 1995.
 
    OTHER ASSETS
 
    Other assets increased $2.6 million to $9.0 million at December 31, 1995.
Most of the increase resulted from the reversal of valuation reserves against
the Company's deferred tax assets. Other assets decreased from $8.7 million to
$6.4 million at December 31, 1993, and 1994, respectively. This reduction was
primarily a result of the reduction in tax assets.
 
    REO
 
    At December 31, 1995, the Company had $2.7 million in REO comprised of eight
commercial properties with carrying values totaling $2.0 million and three
parcels of land zoned for residential purposes valued at $679 thousand. The
Company sold $4.2 million of REO during 1995 and incurred REO valuation
adjustments and property maintenance expenses of $525 thousand. At December 31,
1994, the Company had $2.3 million in REO comprised of three commercial
properties with carrying values totaling $2.2 million, one single family
residence valued at $100 thousand and land zoned for residential purposes of $50
thousand. The Company sold $4.8 million of REO during 1994 and incurred REO
valuation adjustments and property maintenance expenses of $641 thousand; these
net expenses were reported as noninterest expense in the consolidated statements
of operations. REO is carried at the lower of cost or current fair market value
less estimated selling costs in the consolidated balance sheets as a component
of other assets. As of December 31, 1995, all REO properties held at December
31, 1994, with the exception of one residential lot, had been sold. Loans to
facilitate the sale of REO during 1995 totaled $2.2 million. These loans were
made in accordance with the Company's credit policies and under similar terms
extended to credit-worthy borrowers. There were no loans to facilitate the sale
of REO during 1994.
 
    DEPOSITS
 
    Total deposits remained relatively constant at $236.1 million and $236.3
million as of December 31, 1995, and 1994, respectively. The year end
composition of deposits changed slightly from December 31, 1994.
Interest-bearing demand and savings account balances decreased $3.5 million to
$77.1 million from $80.6 million at December 31, 1995. Time certificates of
deposit increased $2.4 million to $90.9 million from $88.5 million at December
31, 1994. The increase in year end balances resulted from a special promotion by
Ventura in December 1995.
 
    NOTES PAYABLE AND OTHER LIABILITIES
 
    The Company repaid $125 thousand of notes payable during 1995 from the
proceeds raised through the common stock rights offering during the second
quarter of 1995. The Company did not purchase federal funds during 1995, as
compared to average federal funds purchased in 1994 of $44 thousand.
 
    SHAREHOLDERS' EQUITY
 
    The Company completed a rights offering to shareholders for which gross
proceeds of $6.5 million were wired to the Parent in June 1995. A total of
2,888,888 common shares were issued in connection with this transaction and the
net proceeds amounted to $5.5 million. A substantial portion of the proceeds
from the offering were paid to Ventura for reimbursement of $3.3 million in
connection with interest paid to the Parent on deposits of funds generated by
commercial paper sales. Shareholders' equity totaled $29.5 million at December
31, 1995, an increase of 54.6% from $19.1 million at December 31, 1994.

    million, and $19.3 million at December 31, 1994, and 1993, respectively. The
    amount of interest foregone on loans that were on nonaccrual status were
    approximately $1.3 million, $1.6 million, and $2.2 million for the years
    ended December 31, 1995, 1994, and 1993, respectively. Interest income on
    loans includes amortization of net loan fees of approximately $139 thousand,
    $237 thousand, and $77 thousand for the years ended December 31, 1995, 1994,
    and 1993, respectively.

    The Company's primary source of revenue is net interest income, which is the
difference between the interest and fees earned on loans and investments and the
interest paid on deposits and other funds. The Company's net interest income is
affected by changes in the amount and mix of interest on interest-earning assets
and interest-bearing liabilities and by changes in yields earned on
interest-earning assets and rates paid on interest-bearing liabilities. The
table below sets forth, for the periods indicated, a summary of the changes in
interest income and interest expense resulting from changes in average interest
rates (rate) and changes in average asset and liability balances (volume). The
change in interest due to both rate and volume has been allocated to change due
to rate and volume in proportion to the relationship of absolute dollar amounts
in each. Nonaccrual loans are included in average loan balances.

</TABLE>
 
    Net interest income decreased by $1.4 million, or 9.0%, to $14.4 million
during 1995 compared to 1994, primarily due to a significant decrease in average
interest earning assets. This decrease reflects overall balance sheet shrinkage
to improve liquidity, as well as to achieve compliance with the capital
requirements of the Banks' regulatory agreements. The decrease is partially
offset by a higher net interest margin during 1995, due to changes in interest
bearing liabilities, the reduction in nonperforming assets and higher market
interest rates.
 
    Interest income decreased $1.3 million to $20.8 million for the year ended
December 31, 1995. The decrease in interest income was primarily attributable to
a significant decrease in interest earning assets, principally loans. However,
the net interest margin increased 0.47% and yields on average earning assets
increased 0.88%. The increased yields resulted in part from the overall increase
in market rates during 1995, together with changes in the Company's asset mix,
and the reduction in nonperforming assets.
 
                                      F-37
<PAGE>
    Average interest earning assets were $234.9 million during 1995, a 15.4%
decrease from average earning assets of $277.6 million for 1994. The Company
reduced average interest earning assets to fund a planned reduction of volatile
deposits, particularly title and escrow demand deposits, and institutional
certificates of deposit. Average interest earning assets as a percent of total
average assets decreased from 94.0% to 92.41% for the years ended December 31,
1995, and 1994, respectively.
 
    Average balances for loans, the largest and highest yielding component of
earning assets, decreased 24.6% during 1995. Loan yields increased by 1.40%
reflecting a decrease in nonaccrual loans, and higher yields on new loans and
repricing loans.
 
    Average investment securities increased $5.6 million to $43.3 million for
the year ended December 31, 1995, and average yields increased 0.22% largely
because of the yield curve inversion noted during 1995.
 
    Average balances for federal funds sold and average yields increased $4.8
million and 1.43% to $31.3 million and 5.80% for the year ended December 31,
1995. Management noted the inversion of the yield curve at midyear and was able
to maintain relatively high balances invested in federal funds sold through the
remainder of 1995.
 
    Interest expense increased $100 thousand to $6.4 million from $6.3 million
for the years ended December 31, 1995, and 1994, respectively. The increase in
interest expense was primarily attributable to an increase in the Company's
average cost of funds on interest-bearing deposits to 3.85% during 1995 from
3.17% due primarily to rising market interest rates.
 
    The increase in the cost of funds was offset by a 16.4% decrease in average
interest bearing deposits from $197.4 million to $164.9 million for the years
ended December 31, 1995, and 1994, respectively. Average deposits decreased from
$272.9 million to $227.9 million for the years ended December 31, 1995, and
1994, respectively, a decrease of 16.5%. During 1995, within the TCD category,
approximately $12.3 million or 55% of the institutional TCDs were replaced by
local market area customer TCDs.
 
    Average deposits were $227.9 million, $272.9 million, and $333.5 million,
for the years ended December 31, 1995, 1994, and 1993, respectively. The 18.2%
and 16.5% decreases in average deposits from 1993 to 1994 and from 1994 to 1995,
respectively, were due to the planned run-off of title and escrow demand
deposits, and institutional and brokered certificates of deposit designed to
improve the Banks' core deposit bases and reduce potentially volatile
liabilities, offset by increases in December 1995 that resulted from marketing
programs designed to improve the public's perception of the Banks, enhance
business development, generate core deposit growth and a renewed expansion of
total banking relationships.
 
    Average interest-bearing deposits decreased 16.4% to $164.9 million from
$197.4 million for the years ended December 31, 1995, and 1994. Average balances
for interest -bearing demand and savings accounts decreased $5.2 million and
$6.9 million to $52.9 million and $27.7 million for the year ended December 31,
1995, from the run-off of escrow and title company accounts. Rates on these
deposits remained relatively constant for the year ended December 31, 1995.
Average balances for time certificates of deposits decreased $20.4 million to
$84.3 million from $104.7 million for the years ended December 31, 1995, and
1994, respectively. This decrease which accounts for the largest percentage of
the overall decrease on average deposits consists principally of institutional
time certificates of deposit that the Company successfully reduced during 1995.
Rates on average time deposits, which comprised 37.0% of average total deposits
for 1995, increased 37.6% to 5.12% from 3.72% for the years ended December 31,
1995, and 1994, respectively. This increase was primarily a result of the higher
market rates.

    PROVISION FOR LOAN LOSSES
 
    For the years ended December 31, 1995, and 1994, the provision for loan
losses was $410 thousand and $3.8 million, respectively. Net loan charge-offs
were $3.3 million and $9.9 million, or 2.05% and 4.66% of average loans and
leases, respectively. Of the 1994 charge-offs, $5.0 million are attributable to
the bulk loan sale which occurred in May 1994. The reduction of loan loss
provision from 1994 to 1995 is due to the continuing improvement in the
Company's credit quality.
 
    The following table summarizes the Company's loan loss reserves and loan
loss experience for the years indicated:

    NONINTEREST INCOME
 
    Noninterest income decreased $1.8 million, or 44.7%, for the year ended
December 31, 1995. However, noninterest income for the year ended December 31,
1994, included one-time gains for the sales
 
                                      F-39
<PAGE>
of the Company's mortgage servicing rights and merchant credit card operations
of $1.4 million and $174 thousand, respectively. As adjusted for these one-time
gains, noninterest income decreased $200 thousand for the year ended December
31, 1995. This adjusted net decrease is partially offset by increased gains on
the sale of SBA loans of $400 thousand realized during 1995. Service charges on
deposit accounts decreased by $250 thousand or 20.5% during 1995 primarily as a
result of the 16.5% reduction in average deposits. Loan fees, which are
comprised of late charges and other service fees related to the Company's credit
products, decreased $347 thousand to $123 thousand for the year ended December
31, 1995, from the sale of the mortgage servicing rights. The sale of the
merchant credit card operations in 1994 resulted in a $42 thousand reduction in
fee income during 1995, which is reported with miscellaneous fee income. The
reduction in mortgage servicing and merchant credit card activity led to a
corresponding decrease in noninterest expenses.
 
    Noninterest income in the future is anticipated to be lower due to the
discontinuance of mortgage activities. Combined net mortgage servicing fees and
gains on sale of mortgage loans included in total noninterest income were $589
thousand and $1.7 million for the years ended December 31, 1994, and 1993,
respectively; no fee income from mortgage servicing was reported for the year
ended December 31, 1995.

</TABLE>
 
    Noninterest expense decreased $1.1 million or 7.1%, in 1995, due primarily
to decreases in REO expenses, occupancy and equipment expenses, professional
services and FDIC/OCC assessments, partially offset by increases in salaries and
employee benefit expenses. Total noninterest expense expressed as a percentage
of net interest income plus other income, commonly referred to as the efficiency
ratio, was 89.53% and 80.71% for the years ended December 31, 1995, and 1994,
respectively.
 
    Salary and employee benefit expense increased by $438 thousand, or 6.8%,
during 1995, primarily as a result of increases in ESOP expenses and a decrease
in loan origination costs. ESOP expenses in 1995 totaled $547 thousand due to
compensation expense recorded for contributions made. As a result, the Trustee
of the ESOP paid off the loan to the Company and all of the shares previously
held in the suspense account, which totalled 185,840 shares as of December 31,
1994, were released to the eligible plan participants. Therefore, as of December
31, 1995, there is no longer any requirement for the Company to contribute to
the ESOP, and there is no longer any loan outstanding between the Company and
the ESOP. No ESOP contributions were made in 1994. The Company also adopted
Statement of Position ("SOP") 93-6 in 1994 which provided for future ESOP
contributions to be expensed at fair market value of the
 
                                      F-40
<PAGE>
Common Stock at the time of the contribution, rather than the historical cost of
$9.00 per share. The expense recorded is based on the average market value of
the stock during the year. Deferred loan origination costs decreased as a result
of decreases in the number of loan originations from 1994 to 1995, which is
evidenced by lower average loan balances during the respective years, and a
decrease in the origination cost recorded per loan as a result of a cost
analysis performed during 1995. In accordance with Statement of Financial
Accounting Standards ("SFAS") No. 91, the Company defers loan origination costs
and amortizes them into loan interest income over the life of each loan. These
deferred costs were $142 thousand and $207 thousand as of December 31, 1995, and
1994, respectively. These increases during 1995 are offset by decreases in
salary expenses and other employee benefits due to staff reductions, as total
full time equivalent employees declined from 141 at December 31, 1994, to 127 at
December 31, 1995.
 
    Occupancy expense decreased $368 thousand, or 17.6%, during 1995, as a
result of a decrease in amortization on leasehold improvements, lower rent
expenses and an increase in sublease income, offset by an inventory adjustment
to premises and equipment. During 1994 and 1995, the Company sublet or
terminated leases for office space formerly housing its commercial lending
department, mortgage origination department and administrative personnel, along
with the Wilmington branch location. The Company also negotiated a favorable
renewal of the lease for its Central Operations office, and allowed the lease
for one of its properties to expire during 1995. Equipment expense decreased
$160 thousand, or 19.3%, during 1995, primarily due to a significant decrease in
depreciation expense due to the decline in fixed asset additions during 1995 and
in computer maintenance expenses associated with outsourcing of the data
processing operations in 1994.
 
    Professional services expense decreased $310 thousand, or 16.1%, during
1995, as a result of a decrease in the legal fees related to the settlement and
collection of problem loans, as evidenced by the Company's significant reduction
in nonperforming and classified assets, and the reversal of legal fees incurred
during 1995 that were related to and offset against a legal settlement. FDIC/OCC
assessments decreased $298 thousand or 29.9%, during 1995, primarily due to a
reduction in the semi-annual BIF insurance assessment percentage and a decrease
in average deposits from 1994 to 1995, as the premium is determined as a
percentage of FDIC adjusted deposit balances.
 
    REO expense declined $472 thousand during 1995. REO expense resulting from
fair value adjustments to the REO properties was $263 thousand for the year
ended December 31, 1995, rather than $959 thousand for the year ended December
31, 1994. The reduction in fair value adjustments reflects a stabilization in
the market for distressed properties. When a property is taken into REO, if the
fair value of the property is less than the Company's recorded loans plus
estimated selling costs, a writedown is taken immediately and charged to the
loan loss reserve. Subsequent reductions in fair value based on appraisals are
charged to noninterest expense as writedowns. In addition, REO maintenance
expenses were $263 thousand as compared to $193 thousand for the years ended
December 31, 1995, and 1994, respectively. This increase resulted primarily from
a change in the composition of REO properties held during 1995 towards
commercial rental properties. These writedowns and expenses were partially
offset by gains on sale of REO of $358 thousand and $511 thousand for the years
ended December 31, 1995, and 1994, respectively.
 
    INCOME TAXES
 
    The Company recorded an income tax benefit of $2.4 million for the year
ended December 31, 1995, resulting primarily from the reversal of valuation
allowances that had been established against deferred tax assets in prior years
to fully offset net deferred tax assets. In assessing the realizability of
deferred tax assets, management considers whether it is more likely than not
that some portion or all of the deferred tax assets will not be realized. The
ultimate realization of deferred tax assets is dependent upon the generation of
future taxable income. Management considers projected future taxable income and
tax planning strategies in making this assessment. The necessity for the
valuation allowance was reassessed during 1995 and the valuation allowance was
reversed, resulting in income recognition.
 
                                      F-41
<PAGE>
    Income tax expense of $285 thousand was recorded for the year ended December
31, 1994, reflecting the charge taken to increase the tax valuation allowance in
accordance with the provisions of SFAS No. 109 and to reflect the filing of the
Company's 1993 tax returns. The Company had current tax assets of $1.5 million
at December 31, 1995, representing the remaining benefit from the 1994 and 1995
net operating loss carrybacks to 1992 and other refundable taxes. In addition,
the Company had a net deferred tax asset of $1.4 million, which resulted
primarily from timing differences in the deduction of bad debts between the
financial statements and the tax return.
 
1994 COMPARED WITH 1993
 
    NET INTEREST INCOME AND NET INTEREST MARGIN
 
    Net interest income decreased by $1.0 million, or 6.2%, to $15.9 million for
the year ended December 31, 1994, compared to $16.9 million for the year ended
December 31, 1993, primarily due to a significant decrease in average interest
earning assets. These decreases reflect overall balance sheet shrinkage,
beginning in 1993, to improve liquidity as well as to achieve compliance with
the capital requirements of the Banks' regulatory agreements.
 
    Interest income for 1994 decreased $3.8 million, or 14.6%, compared to $22.1
million in 1993, while interest expense decreased $2.7 million, or 30.4%, for
the same period to $6.3 million. The decrease in interest income during 1994 was
primarily attributable to a significant decrease in interest earning assets,
primarily loans. The decrease in interest income was slightly offset by an
increase in the yield on interest earning assets to 7.97% for 1994 versus a
7.37% yield on interest earning assets for 1993, which reflects increases in
market interest rates beginning in 1994 and a change in the mix of assets due to
the declining asset base.
 
    Average interest earning assets were $277.6 million during 1994, a 21.1%
decrease from the average balance of $351.7 million for 1993. The Company
reduced average interest earning assets to fund a planned reduction of volatile
deposits, particularly title and escrow deposits and institutional certificates
of deposit. Average interest earning assets as a percent of total average assets
increased from 92.3% for 1993 to 94.0% for 1994. Loans, the largest and highest
yielding component of earning assets, decreased 26.8% during 1994.
 
    The decrease in interest expense during 1994 was primarily attributable to a
19.8% decrease in average interest bearing deposits from $246.1 million for 1993
to $197.4 million for 1995. In addition, the decrease in interest expense was
affected by a change in the mix of interest-bearing liabilities. Average
noninterest-bearing deposits as a percent of total average deposits increased
from 26.2% for 1993 to 27.7% for 1994. Average deposits decreased from $333.5
million for 1993 to $272.9 million for 1994, a decrease of 18.2%. Average
certificates of deposit greater than $100 thousand decreased from 16.27% of
average total deposits for 1993 to 12.34% of average total deposits for 1994. As
a result of the shift in the mix of liabilities, the average cost of funds
declined to 3.17% during 1994 compared to a 3.41% cost of funds for 1993,
despite increases in market interest rates.
 
    Net interest margin increased to 5.68% from 4.81% for the years ended
December 31, 1994 and 1993, respectively. Most of the increase resulted from the
reduction in non-performing assets and higher market interest rates, which was
partially offset by a decrease in average earning assets, primarily loans.
 
    NONINTEREST INCOME
 
    Noninterest income decreased $756 thousand, or 15.7%, during 1994, primarily
due to a lower level of mortgage activity. Loan fees decreased 60.6% from $1.2
million in 1993 to $470 thousand in 1994, reflecting a significant decrease in
income resulting from mortgage loan originations and servicing during the year.
Net mortgage servicing fees were $317 thousand in 1994, compared with $618
thousand in 1993, a decrease of 48.7%. The Company sold its mortgage servicing
rights for a net gain of $1.4 million in
 
                                      F-42
<PAGE>
May 1994, which was offset by a write-off of $320 thousand. The Company also
sold its mortgage origination unit in June 1994 in return for residual income on
future loan originations by the acquirer. However, due to significant reductions
in mortgage origination activity subsequent to the sale, the acquirer closed the
mortgage origination unit, and no residual income will be generated. Noninterest
income increased in 1994, due to the gain on sale of mortgage servicing and a
gain of $174 thousand on the sale of the merchant credit card operation in March
1994. These increases were offset by a 21.0% decrease in gains on the sale of
SBA loans during 1994. The decreases in gains on sale of SBA loans were due
primarily to reduced volume of sales and the deferral of income recognition due
to the timing of such sales. Service charges on deposit accounts decreased
during 1994 as a result of customers maintaining higher average balances to
offset service charge assessments and lower deposit levels.
 
    Miscellaneous fee income decreased 40.0% from $590 thousand in 1993 to $354
thousand in 1994 due to the elimination of the merchant card portfolio during
1994 and certain other recordkeeping services for customers during 1993 and
1994. Miscellaneous fees include merchant card income, cash management service
charges, safe deposit box rentals, charges for items such as money orders,
cashiers' checks and ATM transactions, and reflect usage and transaction volume.
Merchant card income represented 13.0% and 24.9% of total miscellaneous fees
during 1994 and 1993, respectively.
 
    Noninterest income in the future is anticipated to be lower due to the
discontinuance of mortgage activities. Combined net mortgage servicing fees and
gains on sale of mortgage loans included in total noninterest income were $589
thousand and $1.7 million in 1994 and 1993, respectively.
 
    PROVISION FOR LOAN LOSSES AND NONPERFORMING LOANS
 
    In 1994 and 1993, the provision for loan losses was $3.8 million and $16.2
million, respectively. Net loan charge-offs in 1994 and 1993 were $9.9 million
and $5.8 million, respectively, or 4.66% and 1.99% of average loans and leases,
respectively. Of the 1994 charge-offs, $5.0 million are attributable to the bulk
loan sale which occurred in May 1994. The reduction of loan loss provision from
1993 to 1994 is due to a significant decline in the migration of loans to
nonaccrual status or REO during 1994.
 
    At December 31, 1994, the loan loss reserve decreased to $8.3 million
compared to $14.3 million at December 31, 1993. The ratio of the loan loss
reserves to outstanding loans and leases at December 31, 1994, and 1993 was
4.92% and 5.35%, respectively.
 
    The coverage ratio, or the ratio of loan loss reserves to nonperforming
loans, was 103.98% and 72.15%, at December 31, 1994 and 1993, respectively.
Loans past due 90 days or more and still accruing totaled $331 thousand and $552
thousand at December 31, 1994, and 1993, respectively.
 
    At December 31, 1994, loans totaling $7.6 million were on nonaccrual status,
compared with $18.9 million at December 31, 1993. As of December 31, 1994, the
Company had restructured loans in the amount of $2 thousand, compared to $348
thousand at December 31, 1993.
 
    Total nonperforming loans as a percent of total loans outstanding were 4.73%
and 7.41% at December 31, 1994 and 1993, respectively.
 
    NONINTEREST EXPENSE
 
    Noninterest expense decreased $4.8 million, or 22.8%, in 1994, due primarily
to a decrease in REO expense, the write-off of goodwill during 1993, and
decreased salaries and employee benefits, occupancy and equipment expenses.
Total noninterest expense expressed as a percentage of net interest income plus
other income, commonly referred to as the efficiency ratio, was 80.71% for 1994
and 95.89% for 1993.
 
    REO expense declined $1.1 million during 1994. The Company incurred
writedowns on REO of $1.4 million during 1993 due to declining market values on
properties that were principally raw land and
 
                                      F-43
<PAGE>
commercial real estate. REO writedowns in 1994 totaled $959 thousand. These
writedowns were partially offset by gains on sale of REO of $1 thousand in 1993
and $511 thousand in 1994.
 
    Salary and employee benefit expense decreased by $659 thousand, or 9.3%,
during 1994 primarily as a result of staff reductions. Total full time
equivalent employees declined from 199 at December 31, 1993 to 141 at December
31, 1994. The decrease in employee benefits expense during 1994 reflected
reduced employee health benefits and the savings of $635 thousand compensation
expense related to the ESOP, which was partially offset by $49 thousand in
401(k) matching contributions. These salary and employee benefit expense
reductions were partially offset by decreased deferred loan origination costs.
These deferred costs were $457 thousand and $207 thousand as of December 31,
1994, and 1993, respectively.
 
    Occupancy expense decreased $491 thousand, or 19.0%, during 1994, as a
result of a decrease in amortization expense related to leased space and an
increase in income from subleases. During 1993 and 1994, the Company sublet or
terminated leases for office space formerly housing its commercial lending
department, mortgage origination department and administrative personnel.
Equipment expense decreased $411 thousand, or 33.1%, during 1994, primarily due
to a significant decrease in depreciation expense. The Company outsourced its
data processing in May 1994 with monthly cost savings of approximately $52
thousand. The Company outsourced its courier service in September 1993,
resulting in monthly reductions of approximately $8 thousand.
 
    INCOME TAXES
 
    The Company recorded income tax expense of $285 thousand in 1994. The charge
of $285 thousand was taken to increase the tax valuation allowance in accordance
with the provisions of SFAS No. 109 and to reflect the filing of the Company's
1993 tax returns. The Company recorded an income tax benefit of $3.2 million in
1993, reflecting available carryback to tax years 1990 through 1992. The Company
had a tax asset of $794 thousand at December 31, 1994, representing the
remaining benefit from the 1994 net operating loss carryback to 1992 and other
refundable taxes. In addition, the Company had a net deferred tax asset of $3.1
million which was fully offset by a tax valuation allowance.
 
INFLATION
 
    The assets and liabilities of the Company, except for fixed assets, are
virtually all monetary items. Since the Company maintains a small portion of its
total assets in fixed assets, 0.9% at December 31, 1995, and 0.7% at December
31, 1994, respectively, the potential for inflated earnings resulting from
understated depreciation charges is minimal. High inflation rates could impact
other expense items, such as salaries and occupancy expense.
 
LIQUIDITY AND ASSET/LIABILITY MANAGEMENT
 
    Liquidity management for banks requires that funds be available to pay all
deposit withdrawals and maturing financial obligations and meet credit funding
requirements promptly and fully in accordance with their terms. Over a very
short time frame, for most banks, including the Banks, maturing assets provide
only a limited portion of the funds required to pay maturing liabilities. The
balance of the funds required is provided by liquid assets and the acquisition
of additional liabilities, making liability management integral to liquidity
management in the short term.
 
    The Banks maintain levels of liquidity that they consider adequate to meet
their current needs. The Banks' principal sources of cash include incoming
deposits, the repayment of loans and conversion of investment securities. When
cash requirements increase faster than cash is generated, either through
increased loan demand or withdrawal of deposited funds, the Banks can arrange
for the sale of loan participations and liquidate investments and access their
federal funds lines of credit with correspondent banks or other lines of credit
with federal agencies. Ventura and Frontier have credit lines, for $8 million
and $3 million, respectively, with an unaffiliated financial institution which
enable them to borrow federal
 
                                      F-44
<PAGE>
funds on an unsecured basis. In addition, the Banks have available lines of
credit with the Federal Home Loan Bank of San Francisco equal to 15% of
Ventura's assets and 10% of Frontier's assets which enable them to borrow funds
on a secured basis. At December 31, 1995, the Banks were not obligated to any
entity in connection with their federal funds lines of credit.
 
    Management of the Company has set a minimum liquidity level of 20% as a
target. The Company's average liquid assets (cash and cash equivalents, federal
funds sold, interest bearing deposits with other financial institutions and
investment securities available for sale, less securities pledged as collateral
and outgoing cash letters) as a percentage of average assets of the Company
during 1995, 1994, and 1993 was 23.3%, 18.6% and 13.6%, respectively. Average
liquidity for 1995, 1994, and 1993, expressed as a percent of average
liabilities, was 25.7%, 20.0%, and 16.6%, respectively. From 1993 to 1995, the
Company underwent significant balance sheet restructuring, as evidenced by the
substantial reductions in assets, loans, and deposits, which accounts for the
improved liquidity. The loan to deposit ratios for the Company at December 31,
1995, 1994, and 1993 were 64.5%, 67.6% and 79.6%, respectively.
 
    Although the Banks do not currently purchase brokered deposits, in the past,
both Ventura and Frontier have, to a certain degree, funded growth in their
assets through demand deposits of title and escrow companies and by the issuance
of certificates of deposit to persons, including other financial institutions,
not otherwise having banking relationships with the Banks. Such liabilities are
potentially unstable sources of deposits because they are generally attracted to
the financial institution based primarily upon the interest rate paid by the
institution and the general financial condition of the institution and may be
withdrawn on relatively short notice. Furthermore, the proceeds of such
liabilities are generally invested in relatively low yielding short term
investment securities rather than higher yielding loans. In order to stabilize
its funding sources, the Company has taken action to reduce title and escrow
deposits and institutional deposits as a percentage of total deposits. Demand
deposits owned by title and escrow companies represented 0.1%, 1.2% and 11.3% of
total deposits at December 31, 1995, 1994, and 1993, respectively. Certificates
of deposit held by other financial institutions represented 4.2%, 9.4%, and
11.4% of total deposits at December 31, 1995, 1994, and 1993, respectively, and
brokered CDs represented 1.3% of total deposits at December 31, 1993; the
Company did not have any brokered CDs at December 31, 1995, or 1994.
 
    Although liability management is the key to liquidity management in the
short-term, long-term planning of both assets and liabilities is necessary to
manage net yields. To the extent maturities of assets and liabilities do not
match in a changing rate environment, net yields may be affected.
 
    Parent is a legal entity, separate and distinct from its subsidiaries, and
it must separately meet its liquidity needs. Aside from raising capital on its
own behalf or borrowing from outside sources, Parent may receive additional
funds through dividends paid by, and fees from services provided to its
subsidiaries. Future cash dividends paid to Parent by its subsidiaries will
depend on each subsidiary's future profitability, capital requirements,
restrictions imposed by regulatory agreements and other factors. See "Market
Price of Common Stock and Dividends" and "Risk Factors--Dividend Restrictions."
In addition, the Formal Agreement required the Parent to reimburse Ventura for
$3.3 million in connection with interest paid to Parent on deposits of funds
generated by commercial paper sales. The reimbursement was made during 1995. See
"Risk Factors--Regulatory Agreements and Capital Requirements."
 
    During 1995, Parent paid off notes payable in the amount of $125 thousand
with proceeds from the rights offering and had no notes payable outstanding as
of December 31, 1995. Parent has sufficient cash available to meet its
obligations during 1996.
 
RATE SENSITIVE ASSETS/RATE SENSITIVE LIABILITIES
 
    The objective of asset/liability management is to provide stable growth in
net interest income while minimizing the impact on earnings due to changes in
interest rates. To reduce exposures to interest rate fluctuations, the Company
attempts to match its interest sensitive assets with its interest sensitive
liabilities,
 
                                      F-45
<PAGE>
and maintain the maturity and repricing of these assets and liabilities at
appropriate levels. Rate sensitive assets and liabilities are those instruments
on which interest rates can be adjusted within a short period of time. In recent
years, assets and liabilities have become more interest rate sensitive as a
result of deregulation and increased volatility in interest rates.
 
    One method the Company uses to monitor interest rate sensitivity is by
attempting to match rate sensitive assets to rate sensitive liabilities over
several time periods by using what is called GAP analysis. Set forth in the
table below is the interest rate sensitivity or GAP position of the Company at
December 31, 1995.

    At December 31, 1995, the Company had net repriceable assets (a "positive"
gap) as measured at one year of 9.7% of total assets. The net repriceable assets
over a five-year time horizon totaled approximately $56 million or 20.9% of
total assets. A positive gap implies that the Company is asset sensitive, and
therefore subject to a decline in net interest income as interest rates decline.
In a relatively stable interest rate environment that follows a rise in interest
rates, variable rate liabilities will continue to reprice upward while variable
rate assets, particularly those indexed to prime rate, remain relatively
constant, thereby narrowing net interest margin. As interest rates decline,
variable rate assets reprice at lower rates immediately, while the variable rate
liabilities reprice gradually, resulting in a narrowing of the net interest
margin. The 1995 and 1994 results reflect the situation in which the net
interest margin grew as rates increased, whereas, the 1993 results reflect the
opposite situation, with declines in the net interest margin as rates declined.
 
    To measure the earnings impact due to asset sensitivity, the Company has
purchased software to simulate the effect of interest rate changes on the
balance sheet. The Asset/Liability Committees
 
                                      F-46
<PAGE>
("ALCO") of the Banks analyze data produced by this software monthly to
determine the most appropriate manner to counter interest rate risk. Based on
the recommendations from ALCO, the Banks have implemented strategies to counter
the impact of changing interest rates, including the establishment of interest
rate floors on 37% of the variable rate loans at December 31, 1995, to mitigate
the effect on the net interest margin if rates decline, and also by investing in
fixed rate investment securities and increased percentages of fixed rate loans
in the portfolio. Management believes that these strategies are effective in
minimizing the impact on earnings from changes in interest rates. However, no
assurances can be given that this strategy will be successful if market rates
decline below the floors and customers attempt to refinance such loans.
 
CAPITAL RESOURCES
 
    The FDIC Improvement Act requires that for banks to be considered "well
capitalized", they must maintain a leverage ratio of 5.0%, a Tier 1 capital
ratio of 6.0% and a risk-based capital ratio of 10.0% and not be under a written
agreement or capital directive. Banks will be considered "adequately
capitalized" if they maintain a leverage ratio of 4.0%, a Tier 1 risk-based
capital ratio of 4.0%, and a total risk-based capital ratio of 8.0%. The Consent
Order requires Frontier to maintain capital ratios at levels substantially
higher than the levels generally applicable to other national banks. Frontier is
required to maintain a Tier 1 risk-based capital ratio of 9.50% and a leverage
capital ratio of 7.00%. See "Supervision and Regulation-- Potential and Existing
Enforcement Actions". Tier 1 capital consists primarily of common stock,
retained earnings and perpetual preferred stock, less goodwill and other
ineligible items. Tier 2 capital is comprised of limited life preferred stock,
subordinated debt and loan loss reserves limited to 1.25% of total risk weighted
assets. Total risk-based capital is Tier 1 plus Tier 2 capital; however, at
least 50% of total capital must be comprised of Tier 1 capital. The capital
standards specify that assets, including certain off-balance items be assigned
risk weights based on credit and liquidity risk which range from 0% risk weight
for cash to 100% risk weight for commercial loans and certain other assets. The
leverage ratio is Tier 1 capital to adjusted average assets. The Tier 1 capital
ratio is Tier 1 capital to risk weighted assets. The total risk-based capital
ratio is Tier 1 plus Tier 2 capital to risk weighted assets. The following sets
forth the capital ratios for the Company and the Banks at December 31, 1995, and
1994.

(1) In accordance with recent guidance from the Federal Financial Institutions
    Examination Council, regulatory capital includes $548 thousand, which
    represents a $792 thousand cumulative effect adjustment to reduce the
    balance of SBA loans, a portion of which was offset by income recognized
    through amortization and gains on the sales of SBA loans during the 90 day
    recourse period pursuant to generally accepted accounting principles. This
    amount is not reflected in the accompanying financial statements prepared in
    accordance with generally accepted accounting principles.

NEW ACCOUNTING PRONOUNCEMENTS
 
    On January 1, 1995, the Company adopted SFAS No. 114, "Accounting by
Creditors for Impairment of a Loan", as amended by SFAS No. 118, "Accounting by
Creditors for Impairment of a Loan--Income Recognition and Disclosures." This
statement amends SFAS No. 5, "Accounting for Contingencies" and SFAS No. 15,
"Accounting by Debtors and Creditors for Troubled Debt Restructurings." This
statement prescribes that a loan is impaired when it is probable that the
creditor will be unable to collect all contractual principal and interest
payments under the terms of the loan agreement. This statement generally
requires impaired loans to be measured based on the present value of expected
future cash flows discounted at the loan's effective interest rate, or as an
expedient, at the loan's observable market price or the fair value of the
collateral if the loan is collateral dependent. Creditors may select the
measurement method on a loan by loan basis, except that collateral dependent
loans must be measured at the fair value of the collateral if foreclosure is
probable. The statement also prescribes measuring impairment of a restructured
loan by discounting the total expected future cash flows at the loan's effective
rate of interest in the original loan agreement. The effect of initially
adopting this statement is reported as part of the provision for credit losses.
The adoption of SFAS No. 114 and SFAS No. 118 did not have a material impact on
the results of operations or the financial position of the Company taken as a
whole.
 
    The Company adopted SFAS No. 115, "Accounting for Certain Investments in
Debt and Equity Securities" as of December 31, 1993. SFAS No. 115 addresses
accounting and reporting for investments in equity securities that have readily
determinable fair values and for all investments in debt securities. Those
investments are to be classified in three categories and accounted for as
follows: (1) debt securities for which the Company has the positive intent and
ability to hold to maturity are classified as held-to-maturity securities and
reported at amortized cost; (2) debt and equity securities that are bought and
held principally for the purpose of selling in the near term are classified as
trading securities and reported at fair value, with unrealized gains and losses
included in earnings; and (3) debt and equity securities not classified as
either held-to-maturity securities or trading securities are classified as
available-for-sale securities and reported at fair value, with unrealized gains
and losses excluded from earnings and reported in a separate component of
shareholders' equity. Accreted discounts and amortized premiums on investment
securities are included as interest income, and unrealized gains or losses
relating to holding or selling securities are calculated using the specific
identification method.
 
    The Financial Accounting Standards Board ("FASB") has issued Statement of
Financial Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based
Compensation", which encourages companies to account for stock compensation
awards based on their fair value at the date the awards are granted. This
Statement does not require the application of the fair value method and allows
the continuance of current accounting method, which requires accounting for
stock compensation awards based on their intrinsic value as of the grant date.
However, SFAS No. 123 requires proforma disclosure of net income and, if
presented, earnings per share, as if the fair value based method of accounting
defined in this Statement had been applied. The accounting and disclosure
requirements of this statement are effective for financial statements for fiscal
years beginning after December 15, 1995, though earlier adoption is encouraged.
The Company has elected not to adopt the fair value provisions of this
statement.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1. ORGANIZATION AND BASIS OF PRESENTATION
 
    Ventura County National Bank, a national banking organization (VCNB), was
organized on February 17, 1982, and commenced business on October 25, 1982.
Ventura County National Bancorp (separately "Ventura," and with its subsidiaries
on a consolidated basis, the "Company") was organized and incorporated on
February 22, 1984, for the purpose of becoming a bank holding company by
acquiring all of the outstanding common stock of VCNB. Accordingly, on September
12, 1984, all of the shareholders of VCNB exchanged their common stock for an
equal number of shares of the Company's common stock.
 
    During 1989, the Company acquired all of the outstanding shares of Frontier
Group, Incorporated, the parent holding company of Frontier Bank, N. A., in
exchange for cash. The acquisition was accounted for as a purchase.
 
    The consolidated financial statements include the accounts of the Company
and its subsidiaries. All significant intercompany balances and transactions
have been eliminated in consolidation.
 
    The Company's primary operations are related to traditional banking
activities, including the acceptance of deposits and the lending of cash and
investing of money. The Company's customers consist of small to medium-sized
businesses and individuals located primarily in Ventura, Santa Barbara, Orange,
and Los Angeles counties. The Company also originates and sells Small Business
Administration ("SBA") loans through its normal operations.
 
    VCNB conducts its banking operations through four branch offices located in
Ventura County, California, approximately 60 miles northwest of downtown Los
Angeles. VCNB's four branch offices are positioned in Ventura, Camarillo,
Oxnard, and Westlake Village. Frontier is based in La Palma in northwestern
Orange County and has a branch office in Wilmington in southern Los Angeles
County. Ventura's headquarters are located in Oxnard, California.
 
NOTE 2. ACCOUNTING POLICIES
 
    The Company and its subsidiaries follow generally accepted accounting
principles and reporting practices applicable to the banking industry. The
preparation of financial statements in conformity with generally accepted
accounting principles requires the use of management's estimates that affect the
reported amounts of assets and liabilities and the reported amounts of revenues
and expenses during the reporting period. Actual results could differ from those
estimates. The following is a summary of the significant accounting and
reporting policies used in preparing the consolidated financial statements.
 
CASH AND CASH EQUIVALENTS
 
    For purposes of reporting cash flows, cash and cash equivalents include cash
on hand and amounts due from banks.
 
INVESTMENT SECURITIES
 
    In May 1993, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 115, "Accounting for
Certain Investments in Debt and Equity Securities". The Company adopted the
provisions of the new standard in its financial statements as of December 31,
1993. Investments are classified in three categories and accounted for as
follows: 1) debt securities for which the Company has the positive intent and
ability to hold to maturity are classified as held-to-maturity securities and
reported at amortized cost; 2) debt and equity securities that are bought

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 2. ACCOUNTING POLICIES (CONTINUED)
and held principally for the purpose of selling in the near term are classified
as trading securities and reported at fair value, with unrealized gains and
losses included in earnings; and 3) debt and equity securities not classified as
either held-to-maturity securities or trading securities are classified as
available-for-sale securities and reported at fair value in the Consolidated
Balance Sheets, with unrealized gains and losses excluded from earnings and
reported in a separate component of shareholders' equity, net of tax.
 
    Consistent with the provisions of SFAS No. 115, the Company classified its
investment securities as available for sale upon adoption at December 31, 1993,
and recorded an unrealized loss of $122,000, net of tax effect. No portion of
such unrealized loss was previously recognized in operating results prior to the
adoption of SFAS No. 115. Prior to the adoption of SFAS No. 115, all investment
securities were stated at amotized cost, with the exception of investments in
mutual funds, which were deemed equity investments, with adjustments to lower of
cost 26 or market being recorded as a component of equity. During 1994 and 1995,
the Company purchased securities which were classified as either
available-for-sale or held-to-maturity categories at the time of purchase, based
on management's intent and ability to hold certain securities to maturity.
 
    Ventura had no trading securities at December 31, 1994, or 1995.
Mortgage-backed securities consist entirely of Federal Home Loan Mortgage
Corporation (FHLMC) securities; there are no structured notes, CMOs, or other
derivative products in the investment portfolio.
 
    Accreted discounts and amortized premiums on all investment securities are
included in interest income, along with dividend and interest income. Unrealized
and realized gains or losses relating to holding or selling securities are
calculated using the specific identification method.
 
INTEREST AND FEES ON LOANS
 
    Interest on loans is accrued and credited to operations based on the
principal amount outstanding, except that accruals are normally discontinued
whenever payment of principal or interest is in doubt. When a loan is classified
as nonaccrual, all previously accrued interest is reversed. Loan origination
fees and initial direct costs of loan origination are deferred and amortized
over the life of the loan as an adjustment of yield throughout the life of the
related loan. Such fees and costs related to loans held for sale are deferred
and recognized in income as a component of gain or loss on sale of loans when
the related loans are sold.
 
SBA LOANS AND SERVICING INCOME
 
    The portion of loans guaranteed by the SBA, which are originated and are
intended for sale in the secondary market, is carried at the lower of cost or
estimated market value. Funding for SBA programs depends on annual
appropriations by the U.S. Congress, and accordingly, the sale of loans under
this program is dependent on the continuation of such programs.
 
    Gains on sale of the guaranteed portion of SBA loans are recognized to the
extent sales proceeds less amounts necessary to provide required yield
enhancement to the Company for retaining the unguaranteed portion of the loan
exceed the carrying value of the guaranteed portion sold. Gains or losses are
determined using the specific identification method for loans sold and are
recorded as noninterest income as of the date of sale.

NOTE 2. ACCOUNTING POLICIES (CONTINUED)
    The Company sells SBA loans and retains servicing. At the time of the sale,
an evaluation is made of the contractual servicing fee, which is represented by
the differential between the contractual interest rate of the loan and the
interest rate payable to the investor. The present value of the amount by which
the contractual servicing fee exceeds a normal servicing fee, or the Company's
cost of servicing such loans plus a normal profit, whichever is greater, after
evaluation of estimated prepayments on such loans, is considered to be an
adjustment of the sales proceeds, which in turn increases the gain recognized at
the time of the sale. Such gains are only recognized to the extent they do not
exceed the amount deferred as yield enhancement on the unguaranteed portion of
the SBA loan sold. The resultant amount of deferred loan sales proceeds is
amortized using a method which approximates a level yield over the estimated
remaining lives of such loans. The contractual servicing fee is recognized as
income over the lives of the related loans, net of the estimated normal
amortization of the deferred loan sales proceeds. Loan servicing costs are
charged to expense as incurred. When actual loan repayment experience differs
from original estimates, amortization is adjusted accordingly through
operations.
 
LOAN LOSS RESERVE
 
    The loan loss reserve is maintained at a level believed adequate by
management to absorb potential losses on the loan and lease portfolios.
Management's determination of that adequacy is based on an evaluation of the
portfolio, past loan loss experience, current economic conditions, volume,
growth, composition of the portfolio and other relevant factors. In addition,
regulatory authorities have recently required many California financial
institutions to substantially increase their loan loss reserve in recognition of
the inherent risk in the existing economic environment. Management also
considers this factor in calculating the loan loss reserve.
 
    The reserve is increased by provisions for loan losses charged against
income. Loans and leases are charged against the loan loss reserve when
management determines that collectibility of the principal is unlikely.
Recoveries on loans previously charged off are credited to the reserve. Although
management believes the level of the loan loss reserve as of December 31, 1995,
is adequate to absorb losses inherent in the loan portfolio, additional declines
in the local economy may result in increasing losses that cannot be reasonably
predicted at this time.
 
   
    On January 1, 1995, the Company adopted SFAS No. 114, "Accounting by
Creditors for Impairment of a Loan", as amended by SFAS No. 118, "Accounting by
Creditors for Impairment of a Loan - Income Recognition and Disclosures." This
statement amends SFAS No. 5, "Accounting for Contingencies" and SFAS No. 15,
"Accounting by Debtors and Creditors for Troubled Debt Restructurings." This
statement prescribes that a loan is impaired when it is probable that the
creditor will be unable to collect all contractual principal and interest
payments under the terms of the loan agreement. This statement generally
requires impaired loans to be measured based on the present value of expected
future cash flows discounted at the loan's effective interest rate, or as an
expedient, at the loan's observable market price or the fair value of the
collateral if the loan is collateral dependent. Creditors may select the
measurement method on a loan by loan basis, except that collateral dependent
loans must be measured at the fair value of the collateral if foreclosure is
probable. The statement also prescribes measuring impairment of a restructured
loan by discounting the total expected future cash flows at the loan's effective
rate of interest in the original loan agreement. The effect of initially
adopting this statement is reported as part of the provision for credit losses.
The adoption of SFAS No. 114 and SFAS No. 118 did not have a material impact on
the results of operations or the financial position of the Company taken as a
whole.

NOTE 2. ACCOUNTING POLICIES (CONTINUED)
PREMISES AND EQUIPMENT
 
    Premises and equipment are stated at cost, less accumulated depreciation and
amortization computed on a straight-line basis over the estimated useful lives
of the assets or terms of the leases. Net gains and losses on retirement of
disposal of premises are included in net gains on sales of assets.
 
REAL ESTATE OWNED
 
    Real estate acquired through foreclosure or deed-in-lieu-of foreclosure, is
carried at the lower of cost or fair value less estimated costs to sell. At the
time of acquisition, any excess of cost over fair value is charged to the loan
loss reserve. Gains realized on sales and operating income are included in
noninterest income; losses realized on sale, holding expenses and subsequent
declines in fair value are included in noninterest expense, respectively, in the
consolidated statements of operations.
 
INTANGIBLE ASSETS AND DEFERRED LOAN SERVICING FEES
 
    For the year ended December 31, 1993, and for the first half 1994, the cost
of acquired loan servicing rights was capitalized and amortized over the
estimated remaining term of the underlying loan pertfolio. During May, 1994, the
Company sold its mortgage loan servicing department and the related capitalized
loan servicing rights were written off.
 
INCOME TAXES
 
    Deferred tax assets or liabilities shown on the balance sheet are adjusted
to reflect differences between the tax bases of assets and liabilities and their
reported amounts in the financial statements. The adjustments to deferred tax
assets and liabilities plus income taxes currently payable or refundable
represents the income tax provision for the year.
 
    The parent files consolidated U.S. federal and California state income tax
returns.
 
INCOME (LOSS) PER SHARE
 
    Income (loss) per share is computed by dividing net income or (loss) by the
weighted-average number of common shares outstanding and the additional dilutive
effect of stock options outstanding during the period. The dilutive effect of
stock options is computed using the average market price of the Company's common
stock for the period. Shares of Common Stock held by the Trustee of the Employee
Stock Ownership Plan, in suspense as collateral for a loan, are not accounted
for as common stock equivalents until such time as they are released to
participants.
 
    The weighted average number of shares used to compute income per share were
7,833,058, 6,333,835, and 5,635,941 for the years ended December 31, 1995, 1994,
and 1993, respectively. Fully diluted income per share has not been reported for
1995, as the additional dilutive effect of outstanding stock options was
immaterial. Fully diluted per share amounts are not reported in loss years as
such amounts are antidilutive.
 
CURRENT ACCOUNTING PRONOUNCEMENTS
 
    FASB has issued Statement of Financial Accounting Standards ("SFAS") No.
123, "Accounting for Stock-Based Compensation", which encourages companies to
account for stock compensation awards based on their fair value at the date the
awards are granted. This statement does not require the

application of the fair value method and allows the continuance of current
accounting method, which requires accounting for stock compensation awards based
on their intrinsic value as of the grant date. However, SFAS No. 123 requires
proforma disclosure of net income and, if presented, earnings per share, as if
the fair value based method of accounting defined in this Statement had been
applied. The accounting and disclosure requirements of this statement are
effective for financial statements for fiscal years beginning after December 15,
1995, although earlier adoption is encouraged. The Company has elected not to
adopt the fair value provisions of this statement.
 
RECLASSIFICATIONS
 
    Certain reclassifications have been made to prior years' amounts to conform
to current year presentation.
 
NOTE 3. RESTRICTIONS ON CASH AND DUE FROM BANK ACCOUNTS
 
    The Company is required to maintain cash reserve balances on transaction
accounts and non-personal time deposits with the Federal Reserve Bank. These
reserve requirements can be offset by cash balances held at the Company. The
average amount of these reserve balances for the year ended December 31, 1995,
was $1,714,000.
 
NOTE 4. INVESTMENT SECURITIES
 
    As a result of a temporary decline in the market value of
securities-available-for-sale, the Company recorded unrealized losses totaling
$615,000 and $1,178,000, which are included in shareholders' equity on the
consolidated balance sheets at December 31, 1995, and 1994, respectively. The
decline in the market value of the portfolio reflects the current interest rate
environment; such decline is deemed temporary in nature. Several mortgage-backed
securities with a market value of $16,724,000 and an amortized cost of
$17,196,000, at the time of transfer, were transferred from the
available-for-sale to the held-to-maturity category. Previously recorded
unrealized losses with a balance of $297,000 and $433,000 at December 31, 1995,
and 1994, respectively, are included in shareholders' equity and are being
amortized over the securities' remaining lives.
 
    In November 1995, the Financial Accounting Standards Board ("FASB") issued a
"Guide to Implementation of Statement 115 on Accounting for Certain Investments
in Debt and Equity Securities: Questions and Answers" (the "Guide"). The Guide
allows for a one time reassessment of the classification of all securities and,
in connection with such reassessment, permits the reclassification of securities
from the held-to-maturity classification to the available-for-sale
classification as of a single date no later than December 31, 1995, without
calling into question management's intent to hold to maturity the remaining
securities classified as held-to-maturity. In December 1995, the Company
transferred its entire portfolio of held-to-maturity securities with an
amortized cost of $20,213,000 to the available-for-sale classification to allow
for greater flexibility in the Company's investment portfolio. The transfer
resulted in an unrealized gain of $186,000, net of the unamortized portion of
unrealized loss recorded when certain securities were transferred from the
available-for-sale to held-to-maturity classification during 1994. This gain is
included in the unrealized gains/losses on available-for-sale securities in a
separate component of shareholders' equity.

    Included in the loan portfolio are loans on which the Company has ceased the
accrual of interest or renegotiated the terms to provide for a reduction or
deferral of interest. At December 31, 1995, and 1994, such loans amounted to
approximately $4,341,000 and $7,614,000, respectively. Interest foregone on
nonaccrual loans in 1995, 1994 and 1993 totaled $1,254,000, $1,609,000 and
$2,214,000, respectively.
 
    LOAN LOSS RESERVE
 
    At December 31, 1995, the Company had classified $1,942,000 of its loans as
impaired with a specific reserve of $349,000 and $2,399,000 of its loans
impaired with no specific loss reserve determined in accordance with SFAS No.

the Company discontinues recognition of interest income and applies the full
amount of all payments received, whether principal or interest, to the principal
balance of the loan.

NOTE 11. COMMON STOCK AND STOCK OPTIONS
 
    Under a stock option plan approved by the Board of Directors in 1982,
options have been granted to key personnel for a term of ten years exerciseable
at 25% annually at the fair market value at the date of grant. During 1991, the
Company's Board of Directors adopted the Ventura County National Bancorp 1991
Stock Option Plan (1991 Plan). The 1991 Plan provides that incentive stock
options be granted to full-time salaried officers and management level employees
of the Company or its subsidiaries for a term of 10 years exerciseable at 20%
annually at the fair market value at the date of the grant. The 1991 Plan also
provides that nonqualified stock options be granted to directors, key full-time
salaried officers and management level employees of the Company or its
subsidiaries for a term of 10 years, exerciseable at 25% annually at the fair
market value at the date of grant.

    In October 1989, the Company established an Employee Stock Ownership Plan
("ESOP"), for which all full-time employees who have completed one year of
service at the Plan year end and all part-time employees who work at least 1,000
hours per year and have completed one year of service at the Plan year end are
eligible. The ESOP was funded by a $4,000,000 loan to the Company from an
independent third party. These debt proceeds were lent to the ESOP which used
the proceeds to acquire 444,444 newly issued shares of the Company's common
stock. The Company raised $1,555,000 from a private placement of 719,580 shares
of common stock and issued $125,000 in notes payable during 1993 and used the
proceeds to retire the remaining principal on the ESOP note payable to a third
party. During 1995, there were 185,840 shares allocated to eligible plan
participants.
 
    Effective January 1, 1994, the Company adopted the provisions of Statement
of Position 93-6, "Employers Accounting for Employee Stock Ownership Plans."
This SOP requires the Company to record compensation expense upon release of
shares to employees at the current fair value of shares released. Prior to
adoption of SOP 93-6, the Company recorded compensation expense for allocated
shares based on the historical cost of $9.00 per share. The adoption of SOP 93-6
had no effect on the reported results of operations of the Company in 1994, as
the Company made no contributions to the Plan in 1994 and no shares were
released to participants.
 
    The Company contributed $547,000 during 1995, and settled all required
contributions between the Company and the ESOP. As a result, the Trustee of the
ESOP paid off the loan to the Company and all of

the shares previously held in the suspense account, which totalled 185,840
shares as of December 31, 1994, were released to the eligible plan participants.
 
    During 1995, 1994 and 1993, the Company incurred $547,000, $nil and $635,000
of compensation expense and $nil, $nil and $112,000 of interest expense,
respectively, related to the ESOP and note payable.
 
NOTE 12. 401(K) PLAN
 
    The Company established a 401(k) plan on October 1, 1987, for which all
full-time employees who have completed 90 consecutive days of service, and all
part-time employees who work at least 1,000 hours per year and have completed 90
consecutive days of service are eligible for enrollment. Employees may
contribute a percentage of their salary pursuant to IRS regulatory maximums, and
under the plan, the Company has a discretionary matching provision. For the
years ended December 31, 1995, and 1994, the Company contributed $48,000 and
$49,000, respectively, to the 401(k) plan and reported such as salaries and
benefits expense.
 
NOTE 13. ESTIMATED FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The fair value estimates presented herein are based on pertinent information
available to management as of December 31, 1995. Considerable judgment is
necessarily required to interpret market data to develop the estimates of fair
value. Accordingly, the estimates presented herein are not necessarily
indicative of the amounts the Company could realize in a current market
exchange. Although management is not aware of any factors that would
significantly affect the estimated fair value amounts, such amounts have not
been comprehensively revalued for purposes of these financial statements since
that date and, therefore, current estimates of fair value may differ
significantly from the amounts presented herein.
 
    The following disclosure of estimated fair value of financial instruments is
made in accordance with SFAS No. 107. The estimates have been determined by the
Company using available market information

    DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The following methods and assumptions were used to estimate the fair value
of each class of financial instruments for which it is practicable to estimate
that value:
 
       CASH AND CASH EQUIVALENTS
 
        For cash and cash equivalents, the carrying amount is a reasonable
    estimate of fair value.
 
       INTEREST BEARING DEPOSITS WITH OTHER FINANCIAL INSTITUTIONS
 
        The fair value of fixed-maturity certificates of deposit is estimated by
    discounting the future cash flows using the current market rates for
    deposits with similar remaining maturities.
 
       INVESTMENT SECURITIES
 
        For securities held as investments, fair value equals quoted market
    prices. Estimated fair value for mortgage-backed securities issued by

       NET LOANS AND LEASES
 
        The fair value of loans is estimated by discounting the future cash
    flows using the current rates at which similar loans would be made to
    borrowers with similar credit ratings and for the same remaining maturities.
    During the second quarter of 1994, $14.1 million in nonperforming loans were
    sold in a bulk sale at 67% of book value. As such, management utilized this
    valuation factor in placing a fair

NOTE 13. ESTIMATED FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)
    value on non-performing loans of $7,945,000 at December 31, 1994. It was not
    practicable to reasonably assess the credit adjustment that would be applied
    in the marketplace for nonperforming loans at December 31, 1995. Therefore,
    nonperforming loans of $4,341,000 are excluded from the carrying amount and
    fair value balances at December 31, 1995. Interest rates on such loans
    ranged from 8.5% - 11.75%, maturities ranged from 0 to 20 years, and
    approximately 85% were real estate secured.
 
       DEMAND DEPOSITS, SAVINGS AND TIME DEPOSITS
 
        The fair value of demand deposits, savings accounts, and certain money
    market deposits is the amount payable on demand at the reporting date. The
    fair value of fixed-maturity certificates of deposit is estimated by
    discounting the future cash flows using the rates currently offered for
    deposits of similar remaining maturities.
 
       OTHER BORROWINGS AND NOTES PAYABLE
 
        Rates currently available to the Company for debt with similar terms and
    remaining maturities are used to estimate fair value of existing debt. At
    December 31, 1994, the differential between the note payable's carrying
    value and its discounted value was insignificant.
 
       COMMITMENTS TO EXTEND CREDIT AND STANDBY LETTERS OF CREDIT
 
        The fair value of commitments is estimated using the fees currently
    charged to enter into similar agreements, taking into account the remaining
    terms of the agreements and the present credit-worthiness of the
    counter-parties. The fair value of letters of credit is based on fees
    currently charged for similar agreements or on the estimated cost to
    terminate them or otherwise settle the obligations with the counter-parties
    at the reporting date. Current rates have increased since the commitments
    were made, yet the fee applied to the balance of commitments outstanding
    resulted in values which are insignificant for 1995 and 1994.
 
NOTE 14. COMMITMENTS AND CONTINGENCIES
 
    FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK
 
    The Company is a party to certain financial instruments in the normal course
of business with a degree of off-balance sheet risk. These instruments include
commitments to extend credit, standby, and commercial letters of credit, which
are designed to meet the needs of the banks' customers.
 
    Commitments to extend credit and standby and commercial letters of credit
are evaluated on a case-by-case basis dependent on each customer's
credit-worthiness. The Company has a rating process which is applied to each
customer. The resulting rating establishes varying levels of required credit
approvals and limits of lending. Monitoring procedures include, but are not
limited to, monthly review of customer accounts by a management committee. The
agreements with the customers normally require collateral and provide
restrictive covenants under generally the same conditions as other lending
activities of the Company. Such collateral varies but may include accounts
receivable, inventories, property and equipment, and real property. The policy
of the Company is to limit lending to 75% of the market value of the collateral.
The Company's exposure to credit loss in the event of non-performance by the
party related to

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 14. COMMITMENTS AND CONTINGENCIES (CONTINUED)
these instruments is represented by the contractual amount of these instruments
in the case of commitments to extend credit. As of December 31, 1995, the
Company did not have commitments to borrowers that have additional borrowings
which have been classified as nonperforming loans and/or as potential problem
loans.
 
    The Company conducts business primarily in Southern California and the
ability of the Company's customers to honor their loan agreements is dependent
on the economic health of this service area. Although the Company generally
provides loans and financial instruments to a broad variety of industries and
customers, at December 31, 1995, approximately $49.3 million represented loans,
commitments and letters of credit to individuals and companies in the real
estate industry. Further, a substantial portion of the collateral for
commercial, financial and agricultural loans is real estate.
 
    COMMITMENTS TO EXTEND CREDIT
 
    Commitments to extend credit represent agreements to lend, on demand and
subject to the restrictive covenants, monies to a customer up to a designated
limit. The commitments generally have fixed expiration dates, variable interest
rates, and normally require payment of an annual fee. Since many of the
commitments historically expire without being fully drawn upon and are subject
to regular monitoring and certain restrictions, the total commitment amounts
outstanding do not necessarily represent future cash requirements. Fees
collected for credit commitments and standby letters of credit, are generally
deferred and amortized over the commitment term on a straight-line basis. The
total amount of commitments to extend credit at December 31, 1995 was
$36,304,000, compared with $30,880,000 at December 31, 1994.
 
    STANDBY AND COMMERCIAL LETTERS OF CREDIT
 
    Standby and commercial letters of credit are conditional commitments issued
by the Company to guarantee the performance of their customers to a third party.
Such letters of credit are normally issued to support performance bonds and
private borrowing arrangements, which include guarantees to suppliers outside of
the United States. Standby and commercial letters of credit amounting to
$2,498,000 were outstanding at December 31, 1995, all of which are expected to
expire by December 31, 1996. Standby and commercial letters of credit amounted
to $2,898,000 as of December 31, 1994, all of which expired by December 31,
1995.
 
    LEASE COMMITMENTS
 
    The Company leases office premises and certain equipment under operating
leases which expire at various dates through 2006. Total rental expense, net of
sublease income, for all non-cancelable operating leases amounted to
approximately $1,259,000, $1,528,000 and $1,682,000 for the three years ended
December 31, 1995, 1994 and 1993, respectively. Future minimum commitments under
these leases of

    LITIGATION
 
    In the normal course of business, the Company is subject to various legal
actions. It is the opinion of management, based upon the opinion of legal
counsel, that such litigation will not have a material impact on the financial
position or results of operations of the Company.
 
NOTE 15. RELATED PARTY TRANSACTIONS
 
    The Company and its subsidiaries have granted loans to certain officers and
directors of the Company, and to businesses with which they are associated, in
the ordinary course of business. These loans are made under terms which are
consistent with the Company's normal lending policies. The amounts of these
loans were approximately $6,291,000 and $7,730,000 at December 31, 1995 and
1994, respectively. During 1995, new loans totaling $528,000 were made, and net
repayments of approximately $1,914,000 were received. During 1994, new loans
totaling $4,608,000 were made, and net repayments of approximately $9,653,000
were received. Interest and fees earned on these loans approximated $548,000,
$762,000 and $1,111,000 in 1995, 1994 and 1993, respectively.
 
NOTE 16. RESTRICTIONS ON SUBSIDIARY DIVIDENDS, LOANS, OR ADVANCES
 
    Certain restrictions exist regarding the ability of the subsidiaries to
transfer funds to the Company in the form of cash dividends, loans or advances.
See Note 17 for discussion regarding restrictions placed on Frontier per the
Consent Order. Generally, the approval of the Comptroller of the Currency is
required to pay dividends in excess of earnings retained in the current year
plus retained net profits for the two preceding years. Also, under Federal
Reserve regulation, a bank subsidiary is limited in the amount it may loan to
affiliates, including the Company, unless such loans are collateralized by
specific obligations.
 
    At December 31, 1995 and 1994, the Company had no loans to affiliates.
 
NOTE 17. CAPITAL RESOURCES AND REGULATORY MATTERS
 
    The Company is required by federal regulation to meet certain capital
standards. The risk-based capital standards require a minimum total capital of
8.0% of "risk-adjusted assets," as defined by the standard. At least half of the
required capital must contain Tier 1 capital, which consists primarily of common
stock and retained earnings, less goodwill. Additionally, the capital standards
require the Company to maintain a minimum leverage ratio of Tier 1 capital to
average assets and a Tier 1 capital to

    REGULATORY MATTERS
 
    At periodic intervals, both the Office of the Comptroller of the Currency
and the FDIC routinely examine the bank subsidiaries' financial statements as
part of their legally prescribed oversight of the banking industry. Based on
these examinations, the regulators can direct that the Company's financial
statements be adjusted in accordance with their findings. Ventura entered into a
Formal Agreement ("Formal Agreement") with the OCC on March 19, 1993 while
Frontier entered into a Consent Order ("Consent Order") with the OCC on March
29, 1993. Based upon an examination of Ventura completed during the fourth
quarter of 1995, the OCC terminated Ventura's Formal Agreement as of November
30, 1995.
 
    The significant requirements of the Consent Order include conducting a
program to evaluate and improve board supervision and management, developing a
program designed to improve lending staff and loan administration, obtaining
current credit information on any loans lacking such information, reviewing and
revising loan policy, establishing an independent loan review program,
developing and implementing a program to collect or strengthen criticized
assets, reviewing and maintaining an adequate loan loss reserve, developing a
new long range strategic plan and annual budget, developing a three-year capital
plan, developing and revising liquidity and funds management policy, correcting
violations of law cited by the OCC and obtaining approval from the OCC to
declare or pay a dividend. In addition, the Consent Order requires that Frontier
appoint a full-time President and Chief Executive Officer, maintain, as of May
31, 1993 and beyond, a Tier 1 capital ratio of 9.50% and a leverage ratio of
7.00% and to continue to develop a program of asset diversification. Kathleen L.
Kellogg became President and Chief Executive Officer at Frontier in November
1994. At December 31, 1995, Frontier's Tier 1 capital and leverage ratios were
13.78% and 9.75%, respectively.
 
    The Company entered into a Memorandum of Understanding ("MOU") with the
Federal Reserve Bank of San Francisco (the "Reserve Bank") acting under
delegated authority from the Federal Reserve Board on March 19, 1994. The
significant requirements of the MOU include submitting a program to improve the
financial condition of the Banks, evaluate and improve board supervision and
management, exit the commercial paper market, comply with Federal Reserve Board
policy regarding management or service fees assessed by the Company and paid by
the Banks and implement steps to improve the effectiveness of the audit and
credit review functions. The MOU further restricts the Company from declaring or
paying a dividend, incurring any debt, adding or replacing a director or senior
executive or repurchasing Company stock without notice to and nondisapproval of
the Reserve Bank. The MOU also requires the Company's Board of Directors to
establish a committee to monitor compliance with the MOU

and ensure that quarterly written progress reports detailing the form and manner

    Management believes Frontier and the Company are in full compliance with all
of the items required under the Consent Order and MOU, respectively.

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors
Ventura County National Bancorp:
 
We have audited the accompanying consolidated balance sheets of Ventura County
National Bancorp and subsidiaries as of December 31, 1995 and 1994, and the
related consolidated statements of operations, shareholders' equity and cash
flows for each of the three years in the period ended December 31, 1995. These
financial 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
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of Ventura County National Bancorp and
subsidiaries as of December 31, 1995 and 1994, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1995 in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
        (UNAUDITED, EXCEPT FOR INFORMATION AS OF AND FOR THE YEAR ENDED
                               DECEMBER 31, 1995)
 
NOTE 1--BASIS OF PRESENTATION
 
    The Company's accounting and reporting policies conform to generally
accepted accounting principles
prescribed for bank holding companies and banks, and predominant banking
industry practice. The interim period financial statements are unaudited. It is
the opinion of Company management that all adjustments consisting of normal,
recurring accruals necessary for a fair presentation of the results of
operations have been reflected therein. Results for the period ending September
30, 1996, are not necessarily indicative of results that may be expected for any
other interim periods or for the year as a whole. For further information, refer
to the Consolidated Financial Statements and footnotes included in the Company's
Annual Report for the year ended December 31, 1995.
 
    The Consolidated Financial Statements include the accounts of the Company
and the following subsidiaries: Ventura County National Bank, ("Ventura") and
Frontier Bank, N.A., ("Frontier"), (jointly, "the Banks"), and Ventura County
Management Services Company, Inc., the last company is currently inactive. All
significant intercompany balances and transactions have been eliminated in
consolidation.
 
CASH AND CASH EQUIVALENTS:
 
    For purposes of reporting cash flows, cash and cash equivalents include cash
on hand and amounts due from banks.
 
SECURITIES:
 
    The Company's securities portfolio includes U.S. Treasury and U.S. federal
agency securities. The Company has classified its investment securities as
held-to-maturity or as available-for-sale; the Company has no trading account
assets.
 
    Securities are classified as available-for-sale when the Company intends to
hold the securities for an indefinite period of time but not necessarily to
maturity. Any decision to sell a security classified as available-for-sale would
be based on various factors, including significant movements in interest rates,
changes in the maturity mix of the Company's assets and liabilities, liquidity
demands, regulatory capital considerations and other similar factors. Securities
classified as available-for-sale are reported at their fair values. Unrealized
holding gains and losses on securities available-for-sale are reported, net of
tax, as a separate component of shareholders' equity. Realized gains and losses
from the sales of available-for-sale securities are reported separately in the
statements of operations. The cost basis of available-for-sale securities is
recorded using the specific identification method.
 
    Securities are classified as held-to-maturity when the Company has both the
intent and ability to hold the securities to maturity on a long-term basis.
Securities held-to-maturity are reported at cost, adjusted for amortization of
premiums and accretion of discounts to maturity or, in the case of
mortgage-backed securities, over the estimated life of the securities.
 
SBA LOANS AND SERVICING INCOME:
 
    The portion of loans guaranteed by the SBA, which are originated and are
intended for sale in the secondary market, is carried at the lower of cost or
estimated market value. Funding for SBA programs depends on annual
appropriations by the U.S. Congress, and accordingly, the sale of loans under
this program is dependent on the continuation of such programs.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
        (UNAUDITED, EXCEPT FOR INFORMATION AS OF AND FOR THE YEAR ENDED
                               DECEMBER 31, 1995)
 
NOTE 1--BASIS OF PRESENTATION (CONTINUED)
    Gains on sale of the guaranteed portion of SBA loans are recognized to the
extent sales proceeds less amounts necessary to provide required yield
enhancement to the Company for retaining the unguaranteed portion of the loan
exceed the carrying value of the guaranteed portion sold. Gains or losses are
determined using the specific identification method for loans sold and are
recorded as noninterest income as of the date of sale.
 
    The Company sells SBA loans and retains servicing. At the time of sale, an
evaluation is made of the contractual servicing fee, which is represented by the
differential between the contractual interest rate of the loan and the interest
rate payable to the investor. The present value of the amount by which the
contractual servicing fee exceeds a normal servicing fee, or the Company's cost
of servicing such loans plus a normal profit, whichever is greater, is
determined. The amount necessary to enhance the yield of the unguaranteed
portion of the SBA loan sold is also determined. The amount of the present value
of the contractual servicing fee income less the amount necessary for the yield
enhancement, is recognized as a servicing fee over the life of the related
loans. If the present value of the servicing fee is less than the amount
necessary for the yield enhancement of the unguaranteed portion, then a
liability is created and the difference is amortized over the life of the
related loans. If the present value of the servicing fee is greater than the
amount necessary for fee enhancement, an asset is not created, instead servicing
fee income is recognized over the life of the loan. Loan servicing costs are
charged to expense as incurred.
 
ACCOUNTING FOR STOCK BASED COMPENSATION:
 
    The Financial Accounting Standards Board has issued SFAS No. 123,
"Accounting for Stock-Based Compensation", which encourages companies to account
for stock compensation awards based on their fair value at the date the awards
are granted. This statement does not require the application of the fair value
method and allows the continuance of the current accounting method, which
requires accounting for stock compensation awards based on their intrinsic value
as of the grant date. However, SFAS No. 123 requires proforma disclosure of net
income and, if presented, earnings per share, as if the fair value based method
of accounting defined in this Statement had been applied. The accounting and
disclosure requirements are effective for financial statements for fiscal years
beginning after December 15, 1995. The Company has elected not to adopt the fair
value provisions of this Statement.
 
NOTE 2--INVESTMENT SECURITIES
 
    As a result of a temporary decline in the market value of
securities-available-for-sale, the Company recorded unrealized losses totaling
$755 thousand and $615 thousand, which are included in shareholders' equity on
the consolidated balances sheets, at September 30, 1996 and December 31, 1995,
respectively. The decline in the market value of the portfolio reflects the
current interest rate environment; such decline is deemed temporary in nature.

NOTE 3--LOANS AND LOAN LOSS RESERVES
 
    A certain degree of risk is inherent in the extension of credit. Credit
losses arise primarily from the loan portfolio, but may also be derived from
other credit-related sources, including commitments to extend credit, guarantees
and standby letters of credit. Actual credit losses and other charges, net of
recoveries, are deducted from the allowance for possible loan losses. Other
charges to the allowance primarily include amounts related to loan foreclosures
at the time of transfer to other real estate owned. A provision for

possible loan losses, which is a charge against earnings, is added to the
allowance based on management's assessment of certain factors including, but not
necessarily limited to, estimated losses from loans and other credit
arrangements; general economic conditions; deterioration in pledged collateral;
historical loss experience; and trends in portfolio volume, maturity,
composition, delinquencies, and nonaccruals. While management has attributed
reserves to various portfolio segments, the allowance is general in nature and
is available for the credit portfolio in its entirety.
 
    Loans are classified as impaired loans when based on current information and
events, it is probable that the Company will be unable to collect all amounts
due according to the contractual terms of the loan agreement. The majority of
the Company's impaired loans represent loans placed on nonaccrual status.
Nonaccrual loans are those which are past due 90 days as to either principal or
interest, or earlier when payment in full of principal or interest is not
expected. When a loan is placed on nonaccrual status, interest accrued but not
received is reversed against interest income. Thereafter, interest income is no
longer recognized and the full amount of all payments received, whether
principal or interest, are applied to the principal balance of the loan. A
nonaccrual loan may be restored to an accrual basis when principal and interest
payments are current, and full payment of principal and interest is expected.
 
    Loans are generally carried at the principal amount outstanding, net of
unearned discounts and deferred fees. Purchased loans are generally carried at
the principal amount outstanding, net of any unamortized discounts or premiums.
Interest on loans, other than certain mortgage loans, is calculated using the
simple interest method. Interest income on discounted loans is generally
recognized over the estimated life of the loans based on methods that
approximate the interest method. Net deferred loan origination fees are
amortized to interest income over the contractual lives of the related loans
using methods that approximate the interest method.

    At September 30, 1996, the Company had loans representing $400 thousand
classified as impaired with a specific reserve of $217 thousand and $2.8 million
of its loans impaired with no specific loss reserve determined in accordance
with SFAS No: 114. However, the company has a general reserve in its allowance
for loan loss that management currently believes is sufficient to cover any
potential losses due to impaired loans that do not have specific reserves. The
average recorded investment in impaired loans during the nine months ended
September 30, 1996, was $3.7 million. Loans classified as impaired at September
30, 1996 included $1.5 million of commercial real estate loans, $1.1 million of
commercial loans, $491 thousand of residential loans and $26 thousand of
personal loans. Once a loan has been identified as impaired, the Company
discontinues recognition of interest income and applies the full

amount of all payments received, whether principal or interest, to the principal
balance of the loan until all principal is paid off. Then payments are posted to
interest until all contractual payments have been made. Interest income that
would have been collected during the first nine months of 1996 and 1995 on
nonaccrual loans had they performed in accordance with their original terms was
approximately $139 thousand and $183 thousand, respectively.
 
NOTE 4--COMMITMENTS AND CONTINGENCIES
 
    In the normal course of business, there are various outstanding commitments
to extend credit which are not reflected in the accompanying consolidated
financial statements. The Company does not anticipate losses as a result of
these transactions. Commercial and standby letters of credit totaled
approximately $2.3 million and $2.5 million at September 30, 1996 and December
31, 1995, respectively. In addition, the Banks had unfunded credit commitments
of $51.4 million and $36.3 million at September 30, 1996 and December 31, 1995,
respectively.
 
    The Company uses the same credit policies in making commitments and
conditional obligations as it does in extending loan facilities to customers.
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 customer.
Collateral held varies, but may include accounts receivable, inventory,
property, plant and equipment, and income-producing commercial properties.
 
NOTE 5--COMMON STOCK AND STOCK OPTIONS
 
    During 1991, the Company's Board of Directors and shareholders adopted the
Ventura County National Bancorp 1991 Stock Option Plan (1991 Plan). The 1991
Plan provides that incentive stock options may be granted to full-time salaried
officers and management level employees of the Company or its subsidiaries for a
term of 10 years exercisable at 20% annually at the fair market value at the
date of the grant. The 1991 Plan also provides that nonqualified stock options
may be granted to directors, key full-time salaried officers and management
level employees of the Company or its subsidiaries for a term of 10 years,
exercisable at 20% annually at the fair market value at the date of grant.
 
    The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option-pricing model with the following weighted-average
assumptions used for grants in 1996 and 1995; no dividend yield for either year;
expected volatility of 43 percent; risk-free interest rates of 6.6 percent; and
expected lives of 10 years. The Company applies APB Opinion 25 and related
Interpretations in accounting for its plans. Accordingly, no compensation cost
has been recognized for its fixed stock option plans. Had compensation cost for
the Company's stock option plans been determined based on the fair value at the
grant dates for awards under those plans consistent with the method of FASB

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS
 
    The following discussion represents information about the results of
operations, financial condition, liquidity and capital resources of Ventura
County National Bancorp and its subsidiaries, Ventura County National Bank and
Frontier Bank, N.A. (together, the "Company"). This information should be read
in conjunction with the 1995 audited consolidated financial statements of the
Company and the notes thereto and the accompanying quarterly unaudited
consolidated financial statements and notes thereto.
 
OVERVIEW
 
    The Company reported net income of $22 thousand for the first nine months of
1996 compared to earnings of $1.4 million for the first nine months of 1995. Net
income for three months ended September 30, 1996 and September 30, 1995 was $575
thousand and $650 thousand, respectively. The year to date 1996 results were
negatively impacted by the $2.5 million reserve that the company recorded during
the second quarter pursuant to a jury verdict resulting from a countersuit to a
suit that the company filed against a former officer of the company and the
company's former legal counsel. Also, the company received a pre-trial
settlement of $950 thousand from the former legal counsel. During the third
quarter the company reached a settlement with the former officer who had
previously won the $2.5 million judgment. The company also settled a lawsuit
which was filed during the third quarter by another former officer. The third
quarter impact to net income was minimal because the reserve recorded in the
second quarter was sufficient to cover both settlements and the costs associated
therewith.
 
    On September 15, 1996 the Company entered into a definitive agreement to be
purchased by and merge into City National Corporation headquartered in Beverly
Hills, California. Pursuant the terms of the agreement, Ventura County National
Bancorp shareholders will receive at their election, cash, stock or a
combination thereof valued at $5.03 per share. The aggregate amount of City
National Corporation Stock available to holders who elect to receive City
National stock shall equal approximately 55% of the total consideration paid for
Ventura County National Bancorp. The purchase price of $5.03 represents a
multiple of 1.6 times Ventura County National Bancorp's June 30, 1996 book
value. Subject to shareholder and regulatory approval, the transaction is
anticipated to close in the first quarter of 1997.
 
    Financial results of the Company for the first nine months ending September
30, 1996 show continued improvement. Net interest income increased to $11.1
million from $10.9 million in the nine months of 1996, as compared to the first
nine months of 1995. The net interest margin decreased to 6.12% for the nine
months ended September 30, 1996, compared to 6.21% for the prior year. The
decrease in the net interest margin can be attributed to higher interest rates
paid on time deposits and due to the slightly lower prime rate and fed funds
rate.
 
    Noninterest income was $1.8 million and $1.6 million for the nine months
ended September 30, 1996 and 1995, respectively. The Company benefited from an
additional $142 thousand in service charge fee income in addition to other small
increases in other non interest income . These increases were offset by a loss
of $86 thousand on the sale of investment securities for the period.
 
    Operating expenses increased from $10.6 million for the nine months ended
September 30, 1995 to $13.0 million for the nine months ended September 30,
1996. The increase in operating expense is largely the result of the accrual for
the above mentioned legal action, as well as merger related expense of
approximately $300 thousand. Absent this accrual, noninterest expense was very
little changed from the prior period. Decreases were observed in Occupancy and
FDIC insurance. These decreases were offset by an increase in Professional Fees,
OREO expense and Advertising.
 
    For the three months ending September 30, 1996, net interest income
increased to $3.8 million from $3.6 million. The net interest margin was
unchanged at 6.18% for the three months ended September 30, 1996, compared to
three months ended September 30, 1995. The increase in net interest income is
the
 
                                      G-13
<PAGE>
result of a $12 million increase in average interest-earning assets for
comparative periods ending September 30, 1996 and September 30, 1995.
 
    Noninterest income increased to $643 thousand from $570 thousand for the
three months ended September 30 1996 and 1995, respectively. Operating expenses
were unchanged at $3.6 million for the three months ended September 30, 1996 and
September 30, 1995 respectively.
 
    Total assets increased slightly to $271.7 million at September 30, 1996, as
compared to $267.8 million at year-end 1995. Gross loans increased to $170.4
million at September 30, 1996, from $157.8 million at December 31, 1995.
 
    The OCC recently completed its regular examination of Frontier and
terminated the consent order which Frontier entered into with the OCC on March
29, 1993. The Company remains subject to a Memorandum of Understanding with the
Federal Reserve Bank.

RESULTS OF OPERATIONS
 
    NET INTEREST INCOME AND NET INTEREST MARGIN
 
    Net interest income is the difference between interest earned on assets and
interest paid on liabilities. The net interest margin is net interest income
expressed as a percentage of average interest-earning assets. Interest income
and expense are affected by changes in the volume and mix of average interest
earning-assets and interest-bearing deposits and other liabilities, as well as
fluctuations in interest rates. The following table sets forth certain
information concerning average interest-earning assets and average
interest-bearing liabilities and the yields and rates thereon. The table also
sets forth a summary of the changes in interest income and interest expense
resulting from changes in average interest rates (rate) and
 
                                      G-14
<PAGE>
changes in average asset and liability balances (volume) for the periods
indicated. Average balances are average daily balances. Nonaccrual loans are
included in total average loans outstanding.

(1) Annualized.
 
(2) Includes loans held available for sale $2.0 million and $1.4 million at
    September 30, 1996 and 1995, respectively.
 
(3) Includes loans on nonaccrual status of approximately $2.7 million and $4.5
    million at September 30, 1996 and 1995, respectively. The amounts of
    interest income forgone year to date on loans that were on nonaccrual status
    at September 30, 1996 and 1995 were approximately $139 thousand and $183
    thousand, respectively. Interest income on loans includes amortization of
    net loan (costs) or fees of approximately $108 thousand and $43 thousand for
    the nine months ended September 30, 1996 and 1995, respectively.
 
    Net interest income increased slightly to $11.1 million for the nine months
ended September 30, 1996, from $10.9 million in the first nine months ending
September 30, 1995, despite a slight decrease in the net interest margin from
6.21% at September 30, 1995 to 6.12% at September 30, 1996. Average yields on
interest-earning assets for the first nine months of 1996 decreased by 15 basis
points to 8.77% from 8.92% for the first nine months of 1995. Average funding
costs for the nine months of 1996 increased by 5 basis points to 3.87% from
3.82% for the first nine months of 1995. Interest income increased slightly to
$16.0 million during the first nine months of 1996, compared to $15.6 million
for the same period in 1995. This increase was primarily due to an $9.8 million
increase in interest-earning assets, the majority of which was
 
                                      G-15
<PAGE>
the commercial, financial, agricultural and SBA loan portfolio, securities and
fed funds sold. Total loans increased to $164.7 million on average compared to
$161.0 million on average in 1995. However, the composition of the loan
portfolio changed. Commercial, financial, agricultural and SBA loans increased
while decreases were noted in all of the other loan categories, with the most
significant decrease in the real estate construction portfolio.
 
    The earnings generated from the increased volume in earning assets were
partially offset by the reduction in rates of 15 basis points. The rate
reduction is evidenced in the commercial, financial, agricultural and SBA loan
portfolio which experienced a reduction of 21 basis points. A large portion of
these loans are tied to the prime rate. During the nine month period ending
September 30, 1995, the prime rate was at 9% as compared to a rate of 8.25% for
a majority of the nine month period ending September 30, 1996. Additionally, the
rate on fed funds sold dropped from 5.89% in the first nine months of 1995, to
5.32% during the first nine months of 1996 which also had a negative impact on
interest income. Average yields on total loans decreased 21 basis points from
10.25% in 1995 to 10.04% for nine months ending September 30, 1996. Average
yields on investments increased by 55 basis points as a result of the shift in
the portfolio from U.S. Treasury securities to higher yielding mortgage backed
securities. Average yields on fed funds sold decreased 57 basis points from the
prior year, primarily as a result of the Federal Reserve Bank lowering short
term interest rates.
 
    Interest expense increased from $4.7 million during the first nine months of
1995 compared to $4.8 million during the first nine months of 1996. This
increase was primarily due to the change in the composition of the deposits.
Certificates of deposit, the highest costing deposits increased $5.8 million
from the prior year, while the rate paid increased 24 basis points. During
December, 1995, Ventura had a marketing promotion which raised $8.0 million in
new certificates of deposit at a rate of 6.0%. The strategy was to develop
relationships with these customers. A majority of the 6.0% certificates of
deposit matured in June, 1996 and most of funds remained with the bank at
current market rates. Rates have decreased during the first nine months of 1996
for the NOW accounts, money market accounts and savings accounts. The NOW and
money market rates have decreased 30 basis points from 2.70% to 2.40%, while the
savings rates have decreased 41 basis points from 2.39% to 1.98%. Total NOW and
money market deposits averaged $2.1 million less during the first nine months of
1996 compared to 1995, while average savings accounts decreased by $2.5 million.
Total interest bearing deposits increased slightly, averaging $166.6 during the
first nine months of 1996 compared to $165.4 in 1995; however, non-interest
bearing demand deposits increased $4.8 million on average in the same period.
 
PROVISION FOR LOAN LOSSES
 
    During the first nine months of 1996, due to the Company's improved asset
quality, the Company recorded no provision for loan losses compared to $410
thousand for the nine months ended September 30, 1995. Gross loan charge-offs
totaled $197 thousand for the quarter and $740 thousand for the nine months
ended September 30, 1996, compared to $854 thousand for the quarter and $3.2
million for the nine months ended September 30, 1995. Recoveries totaled $91
thousand for the quarter and $289 thousand for the nine months ended September
30, 1996, compared to $90 thousand for the quarter and $296 thousand for the
nine months ended September 30, 1995. Nonaccrual loans decreased from $4.3
million at year-end 1995 to $2.7 million at September 30, 1996. Management
believes that current reserve levels are adequate. (Please refer to NOTE
3--LOANS.)
 
NONINTEREST INCOME
 
    Noninterest income increased $165 thousand to $1.8 million for the nine
months ending September 30, 1996, from $1.6 million for the nine months ending
September 30, 1995. Most of the increase is the result of increased service
charges and other income which was partially offset by a loss on the sale of
investment securities of $86 thousand. Service charges on deposit accounts
increased $142 thousand for the nine months ended September 30, 1996, as the
Company increased its core deposit base.
 
                                      G-16
<PAGE>
    Noninterest income increased $73 thousand to $643 thousand from $570
thousand for three months ending September 30, 1996 and 1995. Service charges on
deposit accounts increased $59 thousand to $292 thousand for three months ending
September 30, 1996 from $233 thousand for the three months ending September 30,
1995. In addition, gain on sale of SBA loans increased $151 thousand from $110
thousand for three months ending September 30, 1995 to $261 thousand for the
three months ending September 30, 1996. These increases were offset by decreases
in other income and the absence of securities gains for the three months ending
September 30, 1996. Other noninterest income for the three months ending
September 30, 1996 was $(4) thousand as a result of an adjustment on a
previously completed fixed asset conversion.

</TABLE>
 
    The Company reported noninterest expense of $13.0 million for the first nine
months of 1996 as compared to $10.6 million for the first nine months of 1995.
The net increase reflects the accrual for the legal judgment, increased
professional fees, expenses related to other real estate owned and advertising
expenses, which are partially offset by decreases in occupancy, equipment, and
FDIC assessments.
 
    Noninterest expense as a percentage of average interest-earning assets has
increased significantly due to the accrual for legal proceedings posted in the
nine months ended September 30, 1996. The Company's efficiency ratio, which is
noninterest expense divided by the sum of net interest income plus noninterest
income, increased during the period ended September 30, 1996, mainly as a result
of the legal accrual.
 
    The slight increase in salaries for the nine months ended September 30,
1996, compared to the previous year was offset by staff reductions, as the
number of full-time equivalent staff decreased from 128 at September 30, 1995,
to 125 at September 30, 1996.
 
    Occupancy expense decreased $200 thousand, or 15.4%, for the first nine
months of 1996 to $1.1 million from $1.3 million for the first nine months of
1995. Most of the decrease resulted from decreased amortization on leasehold
improvements, lower rent expenses and an increase in sublease income. The
Company sublet or terminated leases for office space formerly housing its
administration and
 
                                      G-17
<PAGE>
Wilmington branch location; the Company also negotiated a favorable renewal of
the lease for its Central Operations office.
 
    Equipment expense decreased $21 thousand primarily due to a significant
decrease in depreciation and in computer maintenance expense associated with the
outsourcing of data processing operations.
 
    Professional fees incurred a significant increase of $309 thousand, or 54%,
due to higher legal and consulting expenses, increased outside audit fees and
increased property management fees. FDIC assessments decreased $330 thousand as
a result of lower premium rates.
 
    Non interest expense for the three months ending September 30, 1996 and
September 30, 1995 were unchanged at $3.6 million. Salary expense increased $219
thousand to $1.9 million for the three months ending September 30,1996 as
compared to $1.7 million for the same period in 1995. Professional expenses
increased to $283 for three months ending September 30,1996 as compared to $180
thousand for the same period in 1995. ORE Expense was $111 thousand and $33
thousand for three months ending September 30, 1996 and 1995, respectively.
These increases were equally offset by decreases in categories such as
occupancy, FDIC insurance and other expenses.

CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents consist of cash on hand and deposits at
correspondent banks. The Company maintains balances at correspondent banks
adequate to cover daily inclearings and other charges. In accordance with
Federal regulations, reserve balances of $2.6 million were maintained in the
form of deposits with the Federal Reserve Bank at September 30, 1996.
 
    Cash and cash equivalents decreased $9.3 million from $19.9 million at year
end 1995 to $10.6 million at September 30, 1996.
 
FEDERAL FUNDS SOLD
 
    The Company invests or sells its excess cash balances in overnight federal
funds. Federal funds sold decreased $19.5 million, as the Company increased its
investment securities portfolio.
 
INVESTMENT SECURITIES
 
    Investment securities increased $20.1 million to $56.7 million from $36.6
million at September 30, 1996 and December 31, 1995 respectively. The source of
the funds was primarily the reduction of fed funds sold. The Company invests
primarily in U.S Treasury, US government agency and mortgage-backed securities.
Mortgage-backed securities consisted of Federal Home Mortgage Loan Corporation
(FHLMC), Federal National Mortgage Association (FNMA) and Government National
Mortgage Association (GNMA)
 
LOANS
 
    The Company makes loans to small to medium-sized businesses in its service
areas. The Company also originates and sells Small Business Administration
("SBA") loans. The interest rates charged for the loans made by the Company vary
with the degree of risk, the size and maturity of the loans, whether the loan
has a fixed or variable rate, the borrowers' depository relationship with the
Company, and prevailing market interest rates. The Company is primarily a
commercial lender, and most of its loans are floating rate loans tied to prime.
 
    The Company may sell these SBA loans for a variety of reasons, including but
not limited to, liquidity needs or market value fluctuations. As of September
30, 1996, the Company had $2.0 million of these SBA loans available for sale
which, if sold at an 8% premium, would result in a gain of $164 thousand pretax
and $96 thousand after-tax income. Therefore, if the Company had sold these
loans, other income would have been higher by approximately $164 thousand.
 
    During the first nine months of 1996, the Company generated $39.7 million in
new loan fundings and purchased a $10.0 million commercial real estate loan
portfolio. The Company experienced significant paydowns/payoffs, particularly on
mini-perm commercial real estate loans, which resulted in a net increase in
loans of $12.6 million, or 8%, during the first nine months of 1996. The Company
sold $5.9 million of SBA loans that were originated during the first nine months
of 1996, as well as $5 million of SBA loans purchased by the Company in 1995.
The Company continues to focus its marketing efforts to small and mid-sized
businesses. The new originations were principally commercial lines of credit and
commercial real estate loans.
 
    The following tables set forth the maturity distribution of the Company's
loan portfolio (excluding nonaccrual loans) at September 30, 1996, based on

ASSET QUALITY
 
NONACCRUAL, PAST DUE AND MODIFIED LOANS
 
    A certain degree of risk is inherent in the extension of credit. Management
has adopted a policy to maintain the allowance for possible loan and lease
losses at a level considered by management to be adequate to absorb estimated
known and inherent risks in the existing portfolio. The charge to expense is
based on management's evaluation of the quality of the loan and lease portfolio,
the level of classified loans and leases, total outstanding loans and leases,
losses previously charged against the reserve, and current and anticipated
economic conditions. Although management believes the level of the loan loss
reserve as of September 30, 1996, is adequate to absorb losses inherent in the
loan portfolio, declines in the local economy may result in increased losses
than cannot be reasonably predicted at this time.
 
    At September 30, 1996, the loan loss reserve was $5.0 million, as compared
to $5.4 million at December 31, 1995. The ratio of the loan loss reserve to
total outstanding loans and leases was 2.90% at September 30, 1996 and 3.42% at
December 31, 1995. The coverage ratio, or the ratio of loan loss reserves to
nonperforming loans was 159.22% at September 30, 1996 and 121.62% at December
31, 1995, respectively. Nonperforming assets consist of nonperforming loans plus
other real estate owned "OREO" and other foreclosed personal property. The
Company's nonperforming loans fall within two categories: loans past due greater
than 90 days and still accruing interest, and loans on nonaccrual status. The
level of the loan loss reserve reflects management's assessment of the inherent
risk associated with the Company's classified assets and ongoing economic
weakness within the Banks' service areas.
 
                                      G-20
<PAGE>
    In determining income from loans, the Company generally adheres to a policy
of not accruing interest on loans on which a default of principal or interest
has existed for a period of 90 days or more. The Company's policy is to assign
nonaccrual status to a loan if either (i) principal or interest payments are
past due in excess of 90 days, unless the loan is both well secured and in the
process of collection; or (ii) the full collection of interest or principal
becomes uncertain, regardless of the length of past due status, or (iii) unless
the loan is a SBA guaranteed loan and a deferral period has been negotiated.
When a loan reaches nonaccrual status, any interest accrued on such a loan is
reversed and charged against current income. Loans past due more than 90 days
and still accruing interest increased to $422 thousand at September 30, 1996,
from $101 thousand at December 31, 1995. The balance at September 30, 1996
consists of one commercial loan. At September 30, 1996 and December 31, 1995,
the Company had nonaccrual loans of $2.7 million and $4.3 million, respectively.
 
    The Company's OREO balances decreased to $2.4 million at September 30, 1996
from $2.7 million at December 31, 1995. Other foreclosed assets were unchanged
from year end at $878 thousand. During the first nine months of 1996, the
company sold nine properties and acquired five new properties. At September 30,
1996 , the company's OREO consisted of five commercial properties with carrying
values totaling $1.7 million and two parcels of land zoned for residential
purposes valued at $679 thousand. OREO is carried at the lower of cost or
current fair market value less estimated selling costs in the consolidated
balance sheets as a component of other assets. During the nine months ended
September 30, 1996 and 1995, the Company incurred property maintenance expense
related to OREO properties of $139 thousand and $173 thousand, rental income
related to OREO properties of $59 thousand and $56 thousand, respectively. For
the nine months ended September 30, 1996 and 1995. the Company had writedowns,
net of gains on sale, of $161 thousand and ($184) thousand, respectively. The
net writedown of ($184) thousand was the result of gain on sale of OREO in the
amount of $289 thousand and writedowns of $105 thousand for the nine month
period ending September 30, 1995. The net impact of the preceding activity for
the nine months ending September 30, 1996 and September 30, 1995 was a net OREO
expense of $241 thousand and ($67) thousand, respectively.
 
    Troubled debt restructured credits (TDRs) are loans on which the borrower
has failed to perform under the original terms of the obligation. As of
September 30, 1996, and December 31, 1995, the Company had $4.0 million and $3.3
million, respectively. All but one TDR for $200 thousand are performing in
accordance with their restructured terms. TDRs are considered performing is
payments are contractually met for some minimum period of time, typically at
least six months.
 
DEPOSITS
 
    Total deposits at September 30, 1996 increased $1.9 million to $237.9
million from $236.1 million at December 31, 1995. Average deposits increased
slightly for nine months ended September 30, 1996 over the average deposits for
the nine months ended September 30, 1995. The increase is due to the Ventura's

demand deposits. This increase was offset by a slight declines in average
NOW/MMDA and savings balances.

LIQUIDITY AND ASSET/LIABILITY MANAGEMENT
 
    Liquidity management for banks requires that funds be available to pay all
deposit withdrawals and maturing financial obligations and meet credit funding
requirements promptly and fully in accordance with their terms. Over a very
short time frame, for most banks, including the Banks, maturing assets provide
only a limited portion of the funds required to pay maturing liabilities. The
balance of the funds required is provided by liquid assets and the acquisition
of additional liabilities, making liability management important to liquidity
management.
 
    The Banks maintain a level of liquidity that they consider adequate to meet
their current needs. The Banks' principal sources of liquidity include incoming
deposits, repayment of loans and conversion of investment securities. When
liquidity requirements increase faster than generated, either through increased
loan demand or withdrawal of deposited funds, the Banks may arrange for the sale
of loans and investments, or access their Federal funds lines of credit with
correspondent banks or lines of credit with federal agencies.
 
    Management of the Company has set a minimum liquidity level of 20% as a
target. The Company's average liquid assets (average cash and cash equivalents,
federal funds sold, interest-bearing deposits with other financial institutions
and investment securities, less pledged securities, and outgoing cash letters)
as a percentage of average assets of the Company at the quarter ended September
30, 1996, was 26.6%, as compared to 27.5% for the corresponding period in 1995.
The average loan to deposit ratios for the Company for the month of September
30, 1996, and December 31, 1995, were 72.98% and 64.5%, respectively.

    The following table sets forth information concerning the Company's rate
sensitive assets and rate sensitive liabilities as of September 30, 1996. Such
assets and liabilities are classified by the earlier of maturity or repricing
date in accordance with their contractual terms.
 
    Certain shortcomings are inherent in the method of analysis presented in the
following table. For example, although certain assets and liabilities may have
similar maturities or periods to repricing, they may react in different degrees
and at different times to changes in market interest rates. Also, loan
prepayments and early withdrawals of certificates of deposit could cause the
interest sensitivities to vary from those which appear in the table.

    At September 30, 1996, the Company's rate sensitive balance sheet was shown
to be in a positive gap position. The gap between assets and liabilities that
reprice within 3 months was $37.4 million or 14.77% of assets. The cumulative
positive gap for 12 months which reflects the total assets less the total
liabilities that re-price during the 12 month period decreases to $1.6 million
or .63% of total assets. After one year, the cumulative positive gap increases.
A positive gap implies that the Company is asset sensitive, therefore subject to
a decline in net interest income as interest rates decline. In a relatively
stable interest rate environment that follows a rise in interest rates, variable
rate liabilities will continue to reprice upward while variable rate assets,
particularly those indexed to prime rate, remain relatively constant, thereby
narrowing the net interest margin. As interest rates decline, variable rate
assets reprice at lower rates immediately, while the variable rate liabilities
reprice gradually, resulting in a narrowing of the net interest margin. The
Banks have established floors on 31.9% of the variable rate loans to mitigate
the effect on the net interest margin if interest rates decline. The Company's
held-to-maturity investment portfolio consists primarily of fixed-rate
mortgage-backed securities with estimated average lives of between 5 to 6 years.

CAPITAL RESOURCES
 
    The Company and its bank subsidiaries are subject to risk-based capital
regulations adopted by the federal banking regulators in January 1990. These
guidelines are used to evaluate capital adequacy, and are based on an
institution's asset risk profile and off balance sheet exposures, such as unused
loan commitments and standby letters of credit. The regulations require that a
portion of total capital be core, or Tier 1, capital consisting of common
stockholders' equity and perpetual preferred stock, less goodwill and certain
other deductions, with the remaining, or Tier 2, capital consisting of other
elements, primarily subordinated debt, mandatory convertible debts, and
grandfathered senior debt, plus the allowance for loan losses, subject to
certain limitations. As of December 1992, the risk-based capital rules were
further supplemented by a leverage ratio, defined as Tier 1 capital divided by
quarterly average assets after certain adjustments. The minimum leverage ratio
is 3 percent for banking organizations that do not anticipate significant growth
and have well-diversified risk, including no undue interest rate exposure,
excellent asset quality, high liquidity, and good earnings. Other banking
organizations not in this category are expected to have ratios of at least 4 to
5 percent, depending on their particular condition and growth plans. Higher
capital ratios can be mandated by the regulators if warranted by the particular
circumstances or risk profile of a banking organization. In the current
regulatory environment, banking companies must stay "well capitalized", as
defined in the banking regulations, in order to receive favorable regulatory
treatment on acquisitions and favorable risk-based deposits insurance
assessments. Management seeks to maintain capital ratios in excess of the
regulatory minimums. As of September 30, 1996, the capital ratios of the Company
and the Banks exceeded the "well capitalized" thresholds prescribed in the
rules, as reported in the following table:

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section 145 of the Delaware Code authorizes City National to indemnify
directors and officers in certain circumstances against liabilities, including
expenses, incurred while acting in such capacities; provided, generally, that
any such indemnified director or officer acted in good faith and in a manner he
or she reasonably believed to be in the best interests of the corporation and,
in the case of a criminal proceeding, had no reasonable cause to believe his or
her conduct was unlawful. The City National By-laws provide for the
indemnification of directors and officers to the maximum extent permitted by the
Delaware Code.
 
    In addition, the City National Certificate provides that City National shall
eliminate the personal liability of its directors to the fullest extent
permitted by the Delaware Code, and City National has entered into
indemnification agreements with certain of its directors providing for
additional indemnification. City National has policies of directors' and
officers' liability insurance which insure directors and officers against the
cost of defense, settlement, or payment of a judgment under certain
circumstances.
 
    Certain Federal Deposit Insurance Corporation ("FDIC") regulations prohibit
City National from indemnifying, or agreeing to indemnify any director, officer
or employee against any civil money penalty or judgment resulting from any
administrative or civil action instituted by a federal banking agency, or any
other liability or legal expense with regard to such actions if they result in
certain types of final orders or settlements. The FDIC regulations allow City
National to make reasonable indemnification payments to such persons during the
course of such actions, provided the board of directors makes certain
determinations and such person or persons agree to reimburse City National for
any indemnification payments that become impermissible as a result of the final
outcome of the action, other than those for which City National is reimbursed by
insurance.

ITEM 22.  UNDERTAKINGS
 
    (a) The undersigned registrant hereby undertakes
 
                                      II-1
<PAGE>
           (1) to file, during any period in which offers or sales are being
       made, a post-effective amendment to this registration statement:
 
               (A) To include any prospectus required by Section 10(a)(3) of the
           Securities Act;
 
               (B) To reflect in the prospectus any facts or events arising
           after the effective date of the registration statement (or the most
           recent post-effective amendment thereof) which, individually or in
           the aggregate, represent a fundamental change in the information set
           forth in the registration statement. Notwithstanding the foregoing,
           any increase or decrease in volume of securities offered (if the
           total dollar value of securities offered would not exceed that which
           was registered) and any deviation from the low or high end of the
           estimated maximum offering range may be reflected in the form of
           prospectus filed with the SEC pursuant to Rule 424(b) if, in the
           aggregate, the changes in volume and price represent no more than a
           20 percent change in the maximum aggregate offering price set forth
           in the "Calculation of Registration Fee" table in the effective
           registration statement.
 
               (C) To include any material information with respect to the plan
           of distribution not previously disclosed in the registration
           statement or any material change to such information in the
           registration statement.
 
           (2) That, for the purpose of determining any liability under the
       Securities Act, each such post-effective amendment shall be deemed to be
       a new registration statement relating to the securities offered therein,
       and the offering of such securities at that time shall be deemed to be
       the initial BONA FIDE offering thereof.
 
           (3) To remove from registration by means of a post-effective
       amendment any of the securities being registered which remain unsold at
       the termination of the offering.
 
    (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange
Act (and, where applicable, each filing of any employee benefit plan's annual
report pursuant to Section 15(d) of the Exchange Act) that is incorporated by
reference in the registration statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial BONA FIDE offering
thereof.
 
    (c) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the SEC such indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrants in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
    (d) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Prospectus pursuant to
Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such
request, and to send the incorporated documents by first-class mail or equally
prompt means. This includes information contained in documents filed subsequent
to the effective date of the registration statement through the date responding
to the request.
 
    (e) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

City National Corporation
400 North Roxbury Drive
Beverly Hills, California 90210
 
To the Board of Directors:
 
    I have acted as counsel to City National Corporation, a Delaware corporation
("CNC"), in connection with the preparation of the Registration Statement on
Form S-4 (the "Registration Statement") filed by CNC with the Securities and
Exchange Commission (the "SEC").
 
   
    The Registration Statement relates to the issuance of up to 1,744,125 shares
(the "Shares") of CNC's common stock, par value $1.00 per share (the "Common
Stock"), as a portion of the consideration for the merger (the "Merger") of
Riverside National Bank, a national banking association ("Riverside") with and
into City National Bank ("CNB"), pursuant to that certain Agreement and Plan of
Merger, dated as of October 15, 1996, by and among CNC, CNB and Riverside (the
"Merger Agreement").
    
 
    I have examined and am familiar with originals or copies of such documents,
corporate records, and other instruments as I have deemed necessary or
appropriate in connection with this opinion, including, without limitation, (1)
the Registration Statement, (2) the Merger Agreement, (3) the Shareholders'
Agreement, dated as of October 15, 1996, by and among CNC and certain
shareholders of Riverside, (4) the Stock Option Agreement, dated as of October
15, 1996, by and between CNC and Riverside, (5) the Restated Certificate of
Incorporation of CNC, (6) the Bylaws of CNC, and (7) resolutions adopted to the
date hereof by the Board of Directors of CNC.
 
    In my examination, I have assumed the legal capacity of all natural persons,
the genuineness of all signatures, the authenticity of all documents submitted
to me as originals, the conformity to original documents of all documents
submitted to me as certified, conformed or photocopied, and the authenticity of
the originals of such latter documents. As to any facts material to the opinions
expressed herein, other than those assumed, I have relied, without independent
verification, upon the documents referred to above, the accuracy of factual
matters contained therein, and oral or written statements and representations of
officers and other representatives of CNC and others, including, without
limitation, public officials.
 
    I am a member of the Bar of the State of California. This opinion is limited
to the laws of the State of California, the General Corporation Law of the State
of Delaware, and the laws of the United States. I do not express any opinion as
to the laws of any other jurisdiction or as to any other laws of the State of
Delaware.
 
   
    I have assumed the due authorization, execution, and delivery by or on
behalf of each of the parties thereto of the securities and documents referred
to above, other than CNC, and that (a) the Merger will occur and be conducted in
accordance with the terms, conditions, covenants and other provisions of the
Merger Agreement as described in the Registration Statement, (b) all applicable
provisions of the Securities Act of 1933, as amended (the "Securities Act"), and
such state "blue sky" or other securities laws as may be applicable have been or
shall duly be complied with; and (c) the Registration Statement, as finally
amended, shall become effective under the Securities Act.
    
 
    Based upon the foregoing, I am of the opinion that the Shares, when issued
to the shareholders of Riverside in accordance with the provisions of the Merger
Agreement, will be legally issued, fully paid, and nonassessable shares of the
Common Stock of CNC.
<PAGE>
    I consent to the filing of this opinion as an exhibit to the Registration
Statement and to the reference to me under the caption "Legal Matters" in the
prospectus forming a part of the Registration Statement. In giving such consent,
I do not admit that I come within the category of persons whose consent is
required under Section 7 of the Securities Act or the rules or regulations of
the SEC promulgated thereunder.
 
                                          Very truly yours,
 
                                          /s/ RICHARD H. SHEEHAN, JR.
