           CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION
    This prospectus includes forward-looking statements. We have based these
forward-looking statements on our current expectations and projections about
future events. These forward-looking statements are subject to risks,
uncertainties and assumptions, including, among other things:
 
    - adverse changes in our loan and lease portfolios and the resulting credit
      risk-related losses and expenses;
 
    - adverse changes in the economy of the Southern California region, our
      primary market, that could further increase credit-related losses and
      expenses;
 
    - adverse changes in the Southern California real estate market that could
      also negatively affect credit risk, as most of our commercial loans are
      made to borrowers concentrated in Southern California and a substantial
      portion of those loans have real estate as primary or secondary
      collateral;
 
    - the consequences of continued bank acquisitions and mergers in our market,
      resulting in fewer but much larger and financially stronger competitors,
      which could increase competition for financial services to our detriment;
 
    - fluctuations in market rates and prices, which could negatively affect our
      net interest margin, asset valuations and expense expectations; and
 
    - changes in regulatory requirements of federal and state agencies
      applicable to bank holding companies and banks such as Eldorado and its
      banking subsidiaries, Eldorado Bank and Antelope Valley Bank.
 
    We undertake no obligation to publicly update or otherwise revise any
forward-looking statements, whether as a result of new information, future
events or otherwise. In light of these risks, uncertainties and assumptions, the
forward-looking events discussed in this prospectus might not occur.

                        ABOUT ELDORADO BANCSHARES, INC.
 
    Eldorado is a bank holding company. Through our two operating subsidiaries,
Eldorado Bank and Antelope Valley Bank, we offer a broad range of commercial
banking products and services to business and retail customers. Our 25 full
service offices are located primarily in Southern California and the Sacramento
area of Northern California. Eldorado Bank also operates eight loan production
offices, four of which are located in California and four of which are located
in other western states. We augment our traditional banking products and
services with specialized products, including Small Business Administration
("SBA") loans, residential mortgage loans originated for resale into the
secondary market, equipment leases to small and medium-sized businesses and
automobile loans. Eldorado's only significant assets are the shares of stock of
Eldorado Bank and Antelope Valley Bank.
 
    Eldorado Bank and Antelope Valley Bank are incorporated under the laws of
the State of California and are licensed by the California Department of
Financial Institutions. Eldorado Bank is a member of the Federal Reserve System.
Antelope Valley Bank is not and therefore is regulated at the federal level by
the Federal Deposit Insurance Corporation ("FDIC"). The deposits of both Banks
are insured up to applicable limits by the FDIC.
 
                           OUR PRODUCTS AND SERVICES
 
    We market our products and services through four divisions:
 
    - COMMUNITY BANKING DIVISION -- focusing primarily on small and medium-sized
      businesses located in our California markets. Products include commercial,
      consumer and real estate loans, and a broad range of deposit products and
      other non-deposit banking services.
 
    - MORTGAGE BANKING DIVISION -- originating residential mortgage loans in
      California, Arizona, Nevada, Oregon and Washington through eight loan
      production offices and a network of wholesale brokers for sale in the
      secondary market.
 
    - EQUIPMENT LEASING DIVISION -- generating equipment leases primarily
      through wholesale brokers located throughout the United States, servicing
      those leases and from time to time selling blocks of leases to other
      institutions.
 
    - AUTOMOBILE LENDING DIVISION -- purchasing loans to finance the acquisition
      of new and used automobiles originated through approximately 60 automobile
      dealers located in Southern California.

<PAGE>
                                  OUR STRATEGY
 
    Our strategic plan has been and continues to be the establishment and
enhancement of an attractive community banking franchise. The key elements of
our plan are to acquire community banks primarily, but not exclusively, in and
around our Southern California base, to improve core profitability and to
maintain a strong balance sheet. Since 1995, we have acquired four community
banks with combined assets of approximately $1 billion. See "Recent
Developments" and "Business -- Prior Acquisitions."
 
        BUILDING AND ENHANCING AN ATTRACTIVE COMMUNITY BANKING FRANCHISE.  We
    are continually engaged in the identification and evaluation of potential
    acquisitions of community banks in California. We focus primarily on
    community banks that have underperformed relative to their peers but have
    strong lending franchises, niche business lines or low cost deposits that
    would complement our existing operations and branch network and also provide
    opportunities for cost savings through branch overlap or back-office
    consolidation. Consistent with this strategy, on January 22, 1999, we
    completed the acquisition of Antelope Valley Bank. See "Recent
    Developments."
 
        IMPROVING CORE PROFITABILITY.  Our strategy to increase profitability is
    based on
 
     - increasing the sources and volume of fee income, including fees derived
       from originating and servicing SBA loans, selling and servicing equipment
       leases, and originating and selling residential mortgage loans,
 
     - expanding and diversifying our base of relatively low cost funds,
 
     - utilizing our asset generation capability to increase the volume of
       commercial loans and leases that we retain in our portfolio, particularly
       SBA loans, equipment leases and commercial loans to our small business
       customers, and
 
     - actively seeking to improve operating efficiencies.
 
        MAINTAINING A STRONG BALANCE SHEET.  We seek to maintain a strong
    balance sheet by managing the risk of credit-related losses and by striving
    to maintain a capital base sufficient to support our strategic plan. We seek
    to improve the asset quality of the banks we acquire by implementing
    underwriting standards in the acquired banks' loan and lease origination
    programs that place greater emphasis on cash flow than collateral coverage
    as the primary source of loan repayment. To maintain a capital base
    sufficient to support our existing businesses and to permit us to continue
    to expand through acquisitions, our objective is to meet the "well
    capitalized" regulatory standards. See "Supervision and Regulation --
    Capital Adequacy Requirements." Giving effect to the offering and the
    expected use of proceeds therefrom, our Tier 1 and Total Risk-Weighted
    Ratios would have been 9.44% and 10.46%, respectively, and our Tier 1
    Leverage Ratio would have been 6.87% at December 31, 1998.
 
                                  OUR HISTORY
 
    Prior to September 1995, Eldorado's predecessor, SDN Bancorp, Inc. ("SDN"),
owned a single bank which had approximately $56 million in assets and which was
categorized as "critically undercapitalized" by federal regulators. In September
1995, SDN was recapitalized by Dartmouth Capital Group, L.P. ("DCG"), a bank
holding company organized by Robert P. Keller, Eldorado's President and Chief
Executive Officer. Following that recapitalization, Mr. Keller assumed control
of SDN, installed new management and began implementing policies to improve
asset quality and operating performance. DCG is controlled by Mr. Keller and a
majority of Eldorado's directors. See "Management" and "Principal and Selling
Shareholders." Upon the completion of the offering, DCG will continue to be
Eldorado's largest shareholder, owning 14.0% of the outstanding common stock,
and DCG and its affiliates will own, in the aggregate, 39.0% of the outstanding
common stock. See "Risk Factors -- Control by directors, executive officers and
principal shareholders."
 
                                       5
<PAGE>
    Since DCG acquired control of Eldorado, the size and scope of our business
and operations have changed substantially as a consequence of our four
acquisitions. With the exception of the recent acquisition of Antelope Valley
Bank, each of our acquisitions has been accounted for using the purchase method
of accounting. Accordingly, the operating results of each such acquired company
are included in our financial statements only from the date of acquisition. As a
result of those acquisitions and the accounting treatment therefor, our
historical operating results prior to June 30, 1997 are of limited relevance in
evaluating our historical financial performance and predicting our future
operating results.
 
                              PURPOSE OF OFFERING
 
    The principal reason for the offering is to create an active trading market
for our common stock. We believe that the existence of such a market will
increase our ability to complete acquisitions on a stock-for-stock basis.
Although we expect to continue to consider cash acquisitions, we believe that
the boards of directors and shareholders of many prospective acquisition
candidates prefer stock acquisitions because the shareholders who receive stock
are allowed to retain an equity interest in the combined company and to defer
recognition of federal income tax. We can provide no assurance, however, that an
active trading market for our common stock will develop after the offering or
that, even if such a market does develop, we will be able to acquire or will
determine that it is in our best interests to acquire businesses in stock-for-
stock transactions.
 
                               RECENT ACQUISITION
 
    On January 22, 1999, we completed the acquisition of Antelope Valley Bank,
headquartered in Lancaster, California. In connection with the acquisition,
Eldorado issued approximately 2.8 million shares of common stock to Antelope's
shareholders. Antelope operates eight full service branches, of which five are
located in Los Angeles County, two in Kern County and one in San Bernardino
County. As of December 31, 1998, Antelope had total assets of $211.7 million. We
believe that Antelope's strong capital position, significant market presence in
the Antelope Valley area of California and niche consumer lending products are
consistent with our strategy of building and enhancing an attractive community
banking franchise. Because of Antelope's strong name recognition in its local
market, we intend to operate Antelope as a separate subsidiary for the
foreseeable future. The acquisition of Antelope was accounted for as a pooling
of interests. See "Recent Developments."
 
    The financial information presented in this prospectus treats the
acquisition of Antelope Valley Bank as if it had been completed prior to the
periods presented herein and should be read in conjunction with our Supplemental
Consolidated Financial Statements and Notes thereto included elsewhere in this
prospectus.
 
                                  OUR ADDRESS
 
    Our principal executive offices are located at 24012 Calle de la Plata,
Suite 340, Laguna Hills, California 92653. Our telephone number is (949)
699-4344. In August 1998, we changed our name from Commerce Security Bancorp,
Inc. to Eldorado Bancshares, Inc.

(1) Some of Eldorado's principal shareholders and directors who are named in
    this prospectus have agreed to purchase directly from Eldorado a total of
    350,000 of the shares of common stock that Eldorado is offering at a price
    of $9.30 per share. The sale of those shares is not being underwritten by
    the underwriters, and Eldorado is not paying any underwriting discount in
    respect of those shares. The sale of the shares of common stock to the
    underwriters is conditioned upon, among other things, the simultaneous
    closing of the sale of the shares to those principal shareholders and
    directors. In addition, Eldorado has granted the underwriters a 30-day
    option to purchase up to an additional 286,400 shares of common stock. See
    "Underwriting."

    (a) an aggregate of 2,241,216 shares of common stock issuable upon

    (b) approximately 1,043,000 shares of common stock to be reserved for
       issuance under our 1997 Stock Option Plan upon completion of the

       shares will be outstanding with an average exercise price of
       approximately $10.72 per share.

                      SUPPLEMENTAL SUMMARY FINANCIAL DATA
 
    The following supplemental summary financial data of Eldorado is derived
from the Supplemental Selected Financial Data appearing elsewhere in this
prospectus, and should be read in conjunction with the Consolidated Financial
Statements and the Supplemental Consolidated Financial Statements of Eldorado
and the Notes thereto and the information set forth under "Capitalization" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations." The supplemental summary financial information presented in the
following table includes financial information of Antelope Valley Bank as if its
acquisition had been completed at the beginning of the earliest period
presented. As described elsewhere in this prospectus, because of the three
acquisitions that Eldorado completed between September 1995 and June 30, 1997,
which were accounted for under the purchase method of accounting, our historical
operating results prior to June 30, 1997 are of limited relevance in evaluating
our historical financial performance and predicting our future operating
results.

                                  RISK FACTORS
 
    INVESTING IN THE COMMON STOCK WILL PROVIDE YOU WITH AN EQUITY OWNERSHIP
INTEREST IN ELDORADO. AS AN ELDORADO SHAREHOLDER, YOU WILL BE SUBJECT TO RISKS
INHERENT IN OUR BUSINESS. THE VALUE OF YOUR INVESTMENT MAY INCREASE OR DECREASE
AND COULD RESULT IN A LOSS. THE COMMON STOCK OFFERED BY THIS PROSPECTUS DOES NOT
CONSTITUTE A DEPOSIT OR OTHER OBLIGATION OF A BANK AND IS NOT INSURED BY THE
FEDERAL DEPOSIT INSURANCE CORPORATION ("FDIC") OR ANY OTHER GOVERNMENTAL AGENCY.
YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING FACTORS AS WELL AS OTHER INFORMATION
CONTAINED IN THIS PROSPECTUS BEFORE DECIDING TO INVEST IN SHARES OF THE COMMON
STOCK.
 
EFFECT OF RECENT ACQUISITIONS--OUR HISTORICAL OPERATING RESULTS MAY BE OF
  LIMITED USE TO YOU IN
  EVALUATING OUR HISTORICAL PERFORMANCE AND PREDICTING OUR FUTURE RESULTS
 
    Since September 1995, when Dartmouth Capital Group, L.P. ("DCG") acquired
control of SDN Bancorp, Inc., Eldorado's predecessor, our operations have
changed substantially. During the past three years, we have acquired four banks
with combined assets of approximately $1 billion. The acquisition of Eldorado
Bancorp in June 1997, itself, nearly doubled our assets. With the exception of
the recent Antelope Valley Bank acquisition, we used the purchase method of
accounting for each of our three other acquisitions. Therefore, the operating
results of each of those acquired companies are included in our financial
statements only from the date of acquisition. Because of our recent acquisitions
and our use of the purchase method of accounting, our historical operating
results before June 30, 1997 are of limited relevance in evaluating our
historical financial performance and predicting our future operating results.
 
RISKS RELATED TO GROWTH STRATEGY--FAILURE TO INTEGRATE ACQUISITIONS SUCCESSFULLY
  COULD HAVE A NEGATIVE EFFECT ON OUR BUSINESS
 
    Since September 1995, we have experienced rapid growth through acquisitions.
An important element of our business strategy continues to involve active and
substantial efforts to acquire or combine with additional financial institutions
that would complement our existing businesses. We can provide no assurance,
however, that we will be able to identify additional suitable acquisition
targets or complete any acquisitions.
 
    If we are able to identify and complete future acquisitions, our ability to
successfully integrate into our operations any acquired businesses, including
our recent acquisition of Antelope Valley Bank, depends on our ability to
 
    - monitor operations,
 
    - control costs,
 
    - maintain positive customer relations,
 
    - maintain regulatory compliance, and
 
    - attract, assimilate and retain additional qualified personnel.
 
    If we fail to achieve any of those objectives in an efficient and timely
manner, we may experience interruptions and dislocations in our business. Any of
these problems could harm our existing operations, including our ability to
retain the customers of the acquired businesses, operate any acquired business
profitably or otherwise implement our growth strategy. In addition, those types
of concerns may cause our federal or state banking regulators to require us to
delay or forgo any proposed acquisition until those problems have been addressed
to their satisfaction.
 
    Another risk associated with our growth strategy includes the possibility
that there exists or could exist liabilities assumed in connection with an
acquisition, including the presence of any liabilities unknown to Eldorado when
it acquired the company, that may adversely affect our business.
 
    Our failure to manage our acquisition strategy effectively could have a
negative effect on our business.
 
                                       10
<PAGE>
WE ARE DEPENDENT UPON THE CONTRIBUTIONS OF OUR KEY MANAGEMENT PERSONNEL
 
    Our future success depends, in large part, upon the continuing contributions
of our key management personnel. Three of our executive officers have been with
Eldorado for less than a year. The loss of services of one or more key employees
could have a material adverse effect on us.
 
    Our future success is also dependent upon our continuing ability to attract
and retain other highly qualified personnel. Competition for such employees
among financial institutions in California is intense. Any inability to attract
and retain additional key personnel could harm our business. We can provide no
assurance that we will be able to retain any of our key officers and employees
or attract and retain qualified personnel in the future.
 
    Mr. Keller, Eldorado's President and Chief Executive Officer, has an
employment agreement which expires on September 30, 2000. The agreement will
automatically extend for another year unless Mr. Keller or Eldorado gives notice
at least one year prior to the expiration date of the agreement. In addition,
Eldorado is the beneficiary of a key-man life insurance policy on Mr. Keller
with a benefit of approximately $1.3 million. Certain members of our senior
management also have employment or severance agreements with us. See
"--Employment contracts, change in control provisions and employee severance
compensation," "Executive Compensation--Keller Agreement" and "Executive
Compensation--Other Executive Employment Agreements."
 
CONCENTRATION OF BUSINESS IN CALIFORNIA--A DOWNTURN IN THE CALIFORNIA ECONOMY OR
  A SIGNIFICANT NATURAL DISASTER IN CALIFORNIA MAY ADVERSELY AFFECT OUR BUSINESS
 
    CALIFORNIA ECONOMY. Substantially all of our business is located in
California, with a particular concentration in Southern California. As a result,
our financial condition and operating results are subject to changes in economic
conditions in that region. In the early to mid-1990s, California experienced a
significant and prolonged downturn in its economy, which adversely affected
financial institutions, including Eldorado and its predecessors. Although the
general economy in California has recovered from that prolonged recession, we
remain subject to changes in economic conditions in that region. We can provide
no assurance that conditions in the California economy will not deteriorate in
the future and that such deterioration will not have a material adverse effect
on us.
 
    Among other factors, the California economy may be adversely affected by
prolonged weakness in one or more of the Asian economies to which California
exports a substantial amount of products and services. For the nine months ended
September 30, 1998, exports to foreign countries totaled $80.0 billion or
approximately 10% of California's Gross State Product, reflecting a 6.1% decline
from $85.2 million for the comparable period in 1997. California, with its
greater dependence on Asian trade and investment, is more at risk from Asia's
economic problems than the rest of the United States. For the first three
quarters of 1998, exports to Asian countries totaled $41.3 billion and
represented 51.6% of California's total exports, reflecting an 18.7% decrease
from $50.8 billion for the same period in 1997. There can be no assurance that
the State's economy will not be adversely affected by prolonged weakness in one
or more of the Asian economies.
 
    CALIFORNIA CLIMATE AND GEOLOGY. A substantial portion of our assets consists
of loans secured by real estate in California. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations." Historically,
California has experienced, on occasion, significant natural disasters,
including earthquakes, brush fires and, recently, certain significant weather
abnormalities, including flooding and coastal errosion, attributable to the
weather phenomena known as "El Nino" and "La Nina." The availability of
insurance for losses from such catastrophes is limited. The occurrence of one or
more of those circumstances could impair the value of the collateral for our
real estate secured loans and have a material adverse effect on us.
 
                                       11
<PAGE>
CONCENTRATION IN SBA LENDING--CHANGES IN SBA REGULATIONS COULD REDUCE OUR SBA
  LOAN ORIGINATIONS AND REVENUES, WHICH ARE SIGNIFICANT
 
    We make a significant percentage of our loans and derive a significant
percentage of our revenue under the loan programs of the U.S. Small Business
Administration (the "SBA"). Our revenue from SBA loan programs constituted
approximately 12.4% of our total interest and noninterest income for the year
ended December 31, 1998.
 
    In recent years, Congress has considered proposals that would substantially
reduce
 
    - the scope of various SBA programs,
 
    - the level of SBA funding, and
 
    - the attractiveness of the programs that the SBA may offer to both
      borrowers and lenders.
 
If Congress enacts any such type of proposal, our SBA loan originations and our
revenues from originating and servicing such loans could be significantly
reduced. See "Supervision and Regulation--Effect of Governmental Policies and
Legislation--Reliance on SBA Programs."
 
RELIANCE ON POTENTIALLY VOLATILE TITLE AND ESCROW DEPOSITS TO FUND SHORT-TERM
  ASSETS
 
    We fund loans and leases primarily through the deposits of our customers and
various lines of credit. Among these deposits are deposits provided by title or
escrow companies. We consider such deposits to be volatile because the deposit
amounts increase and decrease significantly throughout the course of any given
period. Title and escrow deposits tend to increase significantly at the end of a
month, when real estate closings tend to occur. Such deposits are also subject
to seasonal fluctuations, tending to decrease during those seasons when the
volume of residential real estate transactions is lower. Only a limited number
of our customers control such deposits. As a result, the decision by any one
depositor to withdraw its funds could have a significant immediate effect on our
total deposits at any given time.
 
    As a consequence of their potential volatility, we utilize title and escrow
deposits solely to fund short-term assets, including mostly residential
mortgages held for sale, which are generally sold within 30 days after such
mortgage loans are funded. We believe that we have adequate alternative sources
of liquidity, such as borrowings from the Federal Home Loan Bank of San
Francisco and other lines of credit, to offset any significant fluctuations in
or the complete withdrawal of our title and escrow deposits. We can provide no
assurance, however, that any alternative funding sources will be available at a
reasonable cost if and when needed. If we cannot obtain any necessary
replacement funding on reasonable terms, our business could be harmed. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
CHANGES IN INTEREST RATES MAY ADVERSELY AFFECT OUR BUSINESS
 
    CHANGES IN NET INTEREST INCOME. Our profitability is significantly dependent
on our net interest income. Net interest income is the difference between our
interest income on interest-earning assets, such as loans and leases, and our
interest expense on interest-bearing liabilities, such as deposits. Therefore,
any change in general market interest rates, whether as a result of changes in
the monetary policies of the Federal Reserve or otherwise, can have a
significant effect on our net interest income. Our assets and liabilities may
react differently to changes in overall market rates or conditions because there
may be mismatches between the repricing or maturity characteristics of our
assets and liabilities. As a result, changes in interest rates can affect our
net interest income in either a positive or a negative way.
 
    CHANGES IN THE YIELD CURVE. Changes in the difference between short and
long-term interest rates (commonly known as the "yield curve") may also harm our
business. For example, we use short-term deposits and borrowings to fund
mortgage loans held by Eldorado during the mortgage warehouse period (the period
between the origination of such mortgage loans and their sale into the secondary
market). Such short-term deposits and borrowings yield short-term rates. The
mortgage loans, however, generally yield long-term rates. If the difference
between short-term and long-term interest rates shrinks or disappears, we would
earn less interest income during the mortgage warehouse period.
 
                                       12
<PAGE>
    EFFECT OF CHANGING INTEREST RATES ON MORTGAGE ORIGINATION VOLUME. Changes in
interest rates can also have other significant effects on our mortgage banking
business. In periods of rising interest rates (as occurred during 1994),
financial institutions such as Eldorado typically originate fewer mortgage
loans. In that case, our mortgage banking income may decline. In periods of
declining interest rates (as occurred during 1998), mortgage loan originations
typically increase, particularly those due to refinancings of existing
mortgages. Other effects of fluctuations in interest rates include the
following:
 
    - changes in the revenue received by Eldorado from the sale of mortgage
      loans if there is a change in interest rates between the time the interest
      rate on the mortgage loan is set and the time we sell the loan, and
 
    - changes in the revenue received by Eldorado from the sale of mortgage
      servicing rights to third parties. For example, in periods of declining
      interest rates, sales of servicing rights related to higher interest rate
      loans may be less profitable because of the increased risk of prepayment
      than sales of servicing rights related to lower interest rate loans.
 
    HEDGING RISKS. We retain some risk from changing interest rates until we
sell a mortgage loan, because our purchase and sale commitments are based on
estimates of loan closings (which are sensitive to interest rate changes). In
addition, because the instruments we use to lessen or hedge interest rate risk
may not respond to changes in interest rates to the same degree as the mortgage
loan pipeline being hedged, some interest rate risks remain even in a fully
hedged portfolio. For example, during the fiscal quarter ended December 31,
1998, Eldorado incurred a loss of $1.1 million on hedging activities primarily
because of an unexpected change in the correlation between the value of the
mortgage loans in our pipeline and mortgage-backed securities used for hedging.
 
WE OPERATE IN A HIGHLY COMPETITIVE MARKET
 
    There is intense competition in California and elsewhere in the United
States for banking customers. We experience competition for deposits from many
sources, including credit unions, insurance companies and money market and other
mutual funds, as well as other commercial banks and savings institutions. We
compete for loans and leases primarily with other commercial banks, mortgage
companies, commercial finance companies and savings institutions. In addition,
our Automobile Lending Division competes with the financial services affiliates
of the major automobile manufacturers. Recently, certain out-of-state financial
institutions have entered the California market, which has also increased
competition. Many of our competitors have greater financial strength, marketing
capability and name recognition than we do, and operate on a statewide or
nationwide basis. In addition, recent developments in technology and mass
marketing have permitted larger companies to market loans more aggressively to
our small business customers. Such advantages may give our competitors
opportunities to realize greater efficiencies and economies of scale than we
can. We can provide no assurance that we will be able to compete effectively
against such competition.
 
    Federal legislation enacted in August 1998 eased membership limits on credit
unions, which previously were permitted to serve only members that shared a
single, common bond. We expect that such legislation will increase the ability
of credit unions to compete with community banks, such as Eldorado Bank and
Antelope Valley Bank, for both deposits and loans.
 
WE CANNOT BE CERTAIN THAT THE VALUE OF THE GOODWILL RECOGNIZED IN ACQUISITIONS
  WILL BE REALIZED
 
    As of December 31, 1998, we had total assets of approximately $1.4 billion,
of which $67.4 million, or 4.8% of total assets and 56.4% of shareholders'
equity, was goodwill. The goodwill was recognized in our three acquisitions that
were accounted for using the purchase method of accounting. Our ratios of
tangible common equity to assets, 3.0%, and tangible total equity to assets,
3.9%, at that date were substantially below the average ratios for commercial
banks in our peer group.
 
    We can provide no assurance that the value of our goodwill will ever be
realized. We monitor the effect that certain events and circumstances may have
that would indicate that all or a portion of the carrying amount of goodwill may
no longer be recoverable. In such circumstances, an additional charge to
 
                                       13
<PAGE>
earnings would become necessary to reflect the fact that such goodwill is not
recoverable. Although as of the date of this prospectus, we do not consider the
goodwill on our balance sheet to be impaired, we can provide no assurance that
it will remain so. Any future determination requiring the write-off of a
significant portion of unamortized goodwill could adversely affect Eldorado.
 
PRIOR LOSSES AT PREDECESSOR SUBSIDIARY BANKS
 
    Prior to June 30, 1997, we conducted our banking operations through four
separate bank subsidiaries: Commerce Security Bank, Eldorado Bank, Liberty
National Bank and San Dieguito National Bank. Within the relatively recent past,
high levels of nonperforming assets, a reliance on high-cost brokered deposits
and excessive overhead costs, among other factors, adversely affected Commerce
Security, Liberty and San Dieguito. Adverse economic conditions in California,
including declining real estate values during the early to mid-1990s, were
partly to blame for such problems. Liberty incurred net losses of $1.3 million
in 1994 and $1.5 million in 1993; San Dieguito incurred net losses of $1.1
million in 1995, $1.0 million in 1994 and $2.0 million in 1993; and Commerce
Security, which we acquired on September 1, 1996, incurred net losses of
$371,000 for the three months ended March 31, 1997 and $447,000 for the three
months ended December 31, 1996.
 
    As a result of management's efforts, together with an improved California
economy, we believe that substantial progress has been made toward improving our
operating results. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations." We can provide no assurance, however, that
the operating problems experienced by our prior subsidiaries will not adversely
affect Eldorado in the future.
 
SUPERVISION AND REGULATION--OUR BANKS OPERATE IN A HIGHLY REGULATED ENVIRONMENT
 
    Eldorado and the Banks operate in a highly regulated environment and are
subject to supervision and examination by various federal and state regulatory
agencies. As a bank holding company, Eldorado is subject to regulation and
supervision primarily by the Federal Reserve. Eldorado Bank and Antelope Valley
Bank, as California-chartered commercial banks, are subject to supervision and
regulation primarily by the California Department of Financial Institutions (the
"DFI"). As a member of the Federal Reserve System, Eldorado Bank is also
regulated by the Federal Reserve. Antelope Valley Bank is not a member of the
Federal Reserve System and therefore is regulated at the federal level by the
FDIC.
 
    Federal and California laws and regulations govern numerous matters,
including
 
    - adequate capital and financial condition,
 
    - permissible types, amounts and terms of extensions of credit and
      investments,
 
    - permissible non-banking activities, and
 
    - restrictions on dividend payments.
 
    The federal and state regulators have extensive discretion and power to
prevent or remedy unsafe or unsound practices or violations of law by banks and
bank holding companies. Eldorado and the Banks also undergo periodic
examinations by one or more regulatory agencies. Following such examinations, we
may be required, among other things, to change our asset valuations or the
amounts of required loss allowances or to restrict our operations. Such actions
would result from the regulators' judgments based on information available to
them at the time of their examination. The Banks' operations are also subject to
a wide variety of state and federal consumer protection and similar statues and
regulations. Such federal and state regulatory restrictions limit the manner in
which Eldorado and the Banks may conduct business and obtain financing. Those
laws and regulations can and do change significantly from time to time, and any
such change could adversely affect Eldorado. See "Supervision and Regulation."
 
    Federal and state regulators have the power to impose substantial fines and
other civil and criminal penalties under a variety of circumstances. In October
1998, we discovered, on our own initiative, that, during a two-year period
beginning while Eldorado Bank was operated by prior management, one of its
branches failed to file currency transaction reports under the Bank Secrecy Act
with respect to one of its
 
                                       14
<PAGE>
customers that routinely deposits large amounts of currency with Eldorado Bank.
The Bank Secrecy Act authorizes criminal and civil penalties, including fines,
for the failure to file currency transaction reports. We voluntarily reported
such failure to the U.S. Department of Treasury promptly after we became aware
of the matter. We believe the failure to file was inadvertent and therefore
should not result in the imposition of any criminal penalty. As of the date of
this prospectus, we have not received any communication from the Department of
Treasury regarding our report. We do not know at this point what action, if any,
the Department of Treasury will take in this matter.
 
    As a consequence of the poor financial performance of Commerce Security,
Liberty and San Dieguito during the early and mid-1990s and their resulting
weakened financial condition, each was required to enter into a memorandum of
understanding with their respective supervising regulators. Each of those
memoranda was terminated before or at the same time as DCG acquired control of
such bank. Neither Eldorado nor either of the Banks is subject to any memorandum
of understanding or other extraordinary supervisory agreement with any
regulatory authority. Eldorado did make certain commitments to the Federal
Reserve in connection with the acquisition of Eldorado Bancorp, however. Among
other things, those commitments provide that we will not redeem, retire or
repurchase any of our preferred stock, incur any debt or pay any dividend on the
common stock without the prior approval of the Federal Reserve. See "Supervision
and Regulation."
 
NO PRESENT INTENTION TO PAY DIVIDENDS; RESTRICTIONS ON PAYMENT OF DIVIDENDS BY
  THE BANKS TO ELDORADO; PROHIBITION ON DIVIDENDS BY ELDORADO BANK TO ELDORADO
  WITHOUT PRIOR REGULATORY APPROVAL
 
    We have never paid cash dividends on our common stock and do not plan on
paying such dividends in the foreseeable future. Our ability to declare a
dividend on the common stock will depend upon, among other things, future
earnings, operating and financial condition, capital requirements, general
business conditions, and receipt of regulatory approvals, if then required.
 
    Eldorado is a legal entity separate and distinct from Eldorado Bank and
Antelope Valley Bank. Substantially all of our revenue and cash flow, including
funds available for the payments of dividends and other operating expenses, is
dependent upon the payment of dividends to Eldorado from the Banks. Dividends
payable by each of the Banks are restricted under California law to
 
    - the lesser of its retained earnings or its net income for the latest three
      fiscal years, less dividends previously declared during that period, or
 
    - with the approval of the DFI, the greater of its retained earnings, its
      net income for the last fiscal year or its net income for the current
      fiscal year.
 
    In connection with the June 1997 acquisition of Eldorado Bancorp, Eldorado
Bank paid a dividend of $14.0 million, which exceeded its net income for the
latest three fiscal years. As a result, Eldorado Bank currently may not pay a
dividend without the prior approval of the DFI. The DFI may, in its discretion,
approve the payment of a dividend as long as the amount does not exceed the
greater of its retained earnings (approximately $9.0 million as of December 31,
1998), its net income for its last fiscal year (approximately $9.3 million for
the year ended December 31, 1998), and its net income for its current fiscal
year. As of December 31, 1998, the maximum dividend that Antelope Valley Bank
could pay without prior DFI approval was $1.5 million.
 
    In addition to California law, under Federal Reserve regulations, Eldorado
Bank may not pay a dividend without prior Federal Reserve approval if
 
    - it would exceed its undivided profits as reported in its most recent
      Report of Condition and Income (approximately $9.0 million as of December
      31, 1998), or
 
    - the total of all dividends declared in one year exceeds the total of its
      net income for that year plus the retained net income for the preceding
      two calendar years.
 
Under the second of those tests, Eldorado Bank is currently prohibited from
paying a dividend without the prior approval of the Federal Reserve. We can
provide no assurance that the DFI and the Federal Reserve
 
                                       15
<PAGE>
will approve the payment of any dividend by Eldorado Bank to the Company,
regardless of the amount of Eldorado Bank's earnings. See "Supervision and
Regulation."
 
NO ASSURANCES AS TO ADEQUACY OF ALLOWANCE FOR LOAN AND LEASE LOSSES
 
    We believe that our allowance for loan and lease losses is maintained at a
level adequate to absorb any inherent losses in our loan and lease portfolio.
Management's estimates are used to determine the allowance that is considered
adequate to absorb losses inherent in the existing loan and lease portfolio.
Management's estimates are based on historical loan loss experience, specific
problem loans and leases, current economic conditions that may affect the
borrower's ability to pay, volume, growth and composition of the loan portfolio,
value of the collateral and other relevant factors. These estimates are
inherently subjective and their accuracy depends on the outcome of future
events. Ultimate losses may differ from current estimates. Depending on changes
in economic, operating and other conditions, including changes in interest
rates, that are generally beyond our control, our actual loan and lease losses
could increase significantly. As a result, such losses could exceed our current
allowance estimates. We can provide no assurance that our allowance is
sufficient to cover actual loan and lease losses should such losses be realized.
 
    In addition, the Federal Reserve and the DFI, as an integral part of their
respective supervisory functions, periodically review our allowance for loan and
lease losses. Such regulatory agencies may require us to increase our provision
for loan and lease losses or to recognize further loan or lease charge-offs,
based upon judgments different from those of management. Any increase in our
allowance required by the Federal Reserve or the DFI could have a negative
effect on Eldorado. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
YEAR 2000 PREPAREDNESS
 
    The Year 2000 issue is a computer programming concern that may adversely
affect our information technology systems, such as our item and data processing
applications, as well as so-called embedded technology, such as microprocessors
that control various functions, including our security systems and
telecommunication equipment. The phrase "Year 2000 issue" refers to the concern
that certain computer applications will not be able to distinguish dates in the
twentieth and twenty-first centuries. We have developed a plan to identify and
remedy the material Year 2000 issues that directly affect our systems. This plan
also includes procedures to evaluate the preparedness of our key vendors and
significant customers in addressing the Year 2000 issue. We believe that we have
taken reasonable steps to address our internal Year 2000 concerns and to inquire
about the actions that our vendors and customers have taken to identify and
address the Year 2000 issue. We can provide no assurance, however, that the
impact of the Year 2000 problem on Eldorado or on our vendors and customers will
not adversely affect our business. In particular, it will be difficult for us to
implement viable contingency plans for any adverse effect of the Year 2000 issue
on local or national telecommunications systems or on our local electric
utility. Furthermore, Year 2000 problems may turn out to exist in portions of
important computer programs not now suspected, and we can provide no assurance
that Eldorado will not be adversely affected by issues we have yet to identify.
If we fail to adequately address the Year 2000 issue pertaining to our internal
operations or those of our customers and vendors, that failure could adversely
affect our business. See "Management's Discussion and Analysis of Operations and
Financial Condition--Year 2000 Preparedness."
 
    In addition, bank regulatory agencies, as part of their supervisory
function, are assessing and will continue to assess Year 2000 readiness. The
failure of a financial institution, such as Eldorado, to take appropriate steps
to address deficiencies in its Year 2000 project management process may result
in one or more regulatory enforcement actions which could have a material
adverse effect on such institution. These actions may include the imposition of
fines, or result in the delay or denial of regulatory applications which would
have a material adverse effect on our strategic plan to grow by acquisition. See
"--Risks related to growth strategy--Failure to integrate acquisitions
successfully could have a negative effect on our business."

CONTROL BY DIRECTORS, EXECUTIVE OFFICERS AND PRINCIPAL SHAREHOLDERS
 
    Our directors, executive officers and principal shareholders, together with
their affiliates, will beneficially own 58.6% of the shares of the common stock
outstanding at the closing of the offering. Upon completion of the offering and
giving effect to a partial distribution of shares of common stock that DCG will
make to its partners prior to the completion of the offering, DCG will
beneficially own 14.0% of the shares of common stock then outstanding. As a
result, if such shareholders take a common position, they could control the
outcome of corporate actions requiring shareholder approval, including the
election of directors and the approval of significant corporate transactions,
such as a merger or sale of all or substantially all of our assets. We can
provide no assurance that the investment objectives of such shareholders will be
the same as our other shareholders. See "Management" and "Principal and Selling
Shareholders."
 
WE HAVE EMPLOYMENT CONTRACTS WITH SOME EXECUTIVE OFFICERS THAT PROVIDE FOR
  SEVERANCE COMPENSATION IF THERE IS A CHANGE IN CONTROL AND FOR THE AWARD OF
  STOCK COMPENSATION UPON THE ISSUANCE OF COMMON STOCK
 
    We have entered into employment agreements with Mr. Keller and certain other
of our executive officers and severance agreements with certain executive
officers of Eldorado and the Banks. Those agreements provide for severance
payments if their respective employment arrangements are terminated in
connection with a change in control of Eldorado or the Banks. Those provisions
may have the effect of increasing the cost of acquiring Eldorado, thereby
discouraging future attempts to take over Eldorado or reducing the value
available to shareholders in the event of a takeover. See "Executive
Compensation."
 
    Until our Tier 1 Capital (for regulatory purposes) is greater than $125.0
million, we generally are obligated to grant stock compensation to Mr. Keller
whenever we issue additional shares of stock, whether in connection with the
offering, a future acquisition or otherwise, except upon the exercise of stock
options under our 1997 Stock Option Plan (the "Option Plan"). Mr. Keller's
employment agreement provides that he is entitled to receive an award of
restricted stock equal to approximately 3.1% of the shares of common stock or
common stock equivalents issued by us. In addition, until our Tier 1 Capital is
greater than $125.0 million, the number of shares of common stock available for
issuance under the Option Plan will automatically increase by an amount equal to
approximately 6.4% of the additional shares issued by us. Mr. Keller's
employment agreement provides that he is entitled to receive an option to
purchase shares of stock equal to one-half of the increase in the total number
of shares of common stock issuable under the Option Plan. The compensation
expense attributable to the grant of restricted stock to Mr. Keller is recorded
as unearned compensation and is shown as a separate component of shareholders'
equity. Unearned compensation is amortized to expense over a vesting period that
expires in February 2001, when Mr. Keller is age 62. As of December 31, 1998 and
pro forma for the effect of the offering, we had Tier 1 Capital of $85.3
million. See "Executive Compensation."
 
POSSIBLE FUTURE SALES OF SHARES COULD ADVERSELY AFFECT PREVAILING MARKET PRICES
  FOR OUR STOCK
 
    Sales of substantial amounts of common stock in the public market under Rule
144 or Rule 145 of the Securities Act of 1933, as amended (the "Securities
Act"), or otherwise, or the perception that such sales could occur, may
adversely affect prevailing market prices of the common stock. If the prevailing
market prices are affected, those sales could impair our future ability to raise
capital through an offering of our equity securities or to effect acquisitions
using shares of common stock. As of the date of this prospectus, approximately
2,131,000 shares of common stock, or 15.1% of the shares of common stock that
will be outstanding after the offering, are not subject to any resale
restrictions under the Securities Act, and approximately 10,263,000 shares of
common stock, or 72.8% of the shares of common stock that will be outstanding
after the offering, are available for resale under Rule 144 or Rule 145. Subject
to certain contractual restrictions described elsewhere in this prospectus (see
"Shares Eligible for Future Sale"), all of those shares may be sold currently
subject to applicable volume restrictions. In addition, we have entered into
agreements with our principal shareholders and certain other holders of common
stock that
 
                                       17
<PAGE>
may entitle these holders to require that we register the resale of their common
stock under certain circumstances.
 
LIMITED PRIOR MARKET FOR COMMON STOCK AND POSSIBLE VOLATILITY OF STOCK PRICE
 
    Trading in the common stock has been extremely limited prior to the
offering. Eldorado common stock was not quoted on the Nasdaq National Market
until February 1, 1999. Prior to that time, the common stock traded sporadically
on the OTC Bulletin Board. There can be no assurance that an active public
market for the common stock will develop at any time in the future or continue
if such a market develops. If such a public market develops, the market price of
the common stock may be subject to significant fluctuations in response to
numerous factors, including variations in the annual or quarterly financial
results of Eldorado or our competitors, changes by financial research analysts
in their estimates of the earnings of Eldorado or our competitors or the failure
of Eldorado or our competitors to meet such estimates, conditions in the economy
in general or the banking industry in particular, or unfavorable publicity
affecting Eldorado or the industry. In addition, the equity markets have, on
occasion, experienced significant price and volume fluctuations that have
affected the market prices for many companies' securities and have been
unrelated to the operating performance of those companies. Any fluctuation may
adversely affect the prevailing market price of the common stock.
 
REGULATION OF CHANGES IN CONTROL OF ELDORADO
 
    Any individual, acting alone or with others, who is seeking to acquire 10%
or more of the outstanding common stock must comply with the Change in Bank
Control Act, which requires prior notice to the Federal Reserve for any
acquisition. Any entity that wants to acquire 5% or more of the outstanding
common stock, or otherwise to control Eldorado, may need to obtain the prior
approval of the Federal Reserve under the Bank Holding Company Act of 1956, as
amended. As a result, prospective investors in common stock need to be aware of
and to comply with those requirements, to the extent applicable.
 
                                       18
<PAGE>
                                  THE COMPANY
 
    Eldorado is a Delaware corporation and registered bank holding company under
the Bank Holding Company Act of 1956, as amended (the "BHC Act"). Through its
two operating subsidiaries, Eldorado Bank and Antelope Valley Bank, the Company
offers commercial banking products and services to small and medium-sized
businesses and retail customers from 25 full service offices located primarily
in Southern California and the Sacramento area of Northern California. Our
products include commercial, consumer and real estate loans, a broad range of
deposit products and other non-deposit banking services. As of December 31,
1998, Eldorado, on a supplemental consolidated basis for the acquisition of
Antelope Valley Bank, had total assets of $1.4 billion, deposits of $1.2 billion
and shareholders' equity of $119.5 million.
 
    The Company's principal place of business is 24012 Calle de la Plata, Suite
340, Laguna Hills, CA 92653; its telephone number at that address is (949)
699-4344.
 
                                USE OF PROCEEDS
 
    The net proceeds to Eldorado from the offering (after deducting the
estimated underwriting discounts and commissions) are estimated to be
approximately $18.6 million. Eldorado will not receive any proceeds from the
sale of shares of common stock by the selling shareholders. With the net
proceeds from the offering, Eldorado intends to use
 
    - $12.0 million to redeem all of our outstanding 11% Series B Preferred
      Stock with an aggregate liquidation value of $11.7 million, which is held
      by two of our principal shareholders,
 
    - $338,000 to repay indebtedness to DCG, and
 
    - the balance for general corporate purposes including investment in the
      Banks, which will enable the Banks to increase their interest-earning
      assets. See "Certain Transactions."
 
    The Series B Preferred Stock is redeemable, subject to the prior approval of
the Federal Reserve, at our election on the terms disclosed above. Eldorado
received the approval of the Federal Reserve for such redemption on March 24,
1999. See "Capitalization" and "Certain Transactions."
 
    Eldorado is also considering using some of the net proceeds from the
offering to purchase a portion of the 11 3/4% Subordinated Capital Income
Securities, Series A issued by our subsidiary, CSBI Capital Trust I (the
"Capital Securities"), out of the $27.7 million currently outstanding. Eldorado
has had, and expects to continue to have from time to time in the future,
discussions with the holders of the Capital Securities regarding the terms of
such purchase. Eldorado expects that it would be able to negotiate the purchase
of the Capital Securities at a price between 110% to 115% of their liquidation
value, depending on market conditions and other factors. There can be no
assurance, however, that Eldorado will be able to purchase or determine that it
is in its best interests to purchase any or all of the Capital Securities.

                              RECENT DEVELOPMENTS
 
    ANTELOPE ACQUISITION.  On January 22, 1999, Eldorado completed the
acquisition of Antelope Valley Bank (sometimes referred to in this prospectus as
"Antelope"). Headquartered in Lancaster, California (located approximately 50
miles northeast of Los Angeles), Antelope operates eight full service branches.
As of December 31, 1998, Antelope had total assets of $211.7 million and
deposits of $187.7 million. Antelope's total shareholders' equity as of December
31, 1998 was $21.4 million, resulting in a Tier 1 Leverage Ratio of 8.49%, a
Tier 1 Risk-Weighted Ratio of 11.49% and a Total Risk-Weighted Ratio of 12.70%.
Antelope had total gross loans as of December 31, 1998 of $137.4 million, 60.2%
of which were consumer loans, 27.1 % of which were commercial and industrial
loans and 12.7% of which were real estate loans. Antelope's consumer lending
focuses primarily on indirect automobile finance, which constituted
approximately 52.0% of Antelope's total portfolio loans as of December 31, 1998.
Loans to finance the purchase of used automobiles constituted the majority of
Antelope's total automobile loans at December 31, 1998. See "Supplemental
Selected Financial Data" and Eldorado's Supplemental Consolidated Financial
Statements and the Notes related thereto presented elsewhere in this prospectus.
 
    Antelope's branches have a significant market share of the deposit base in
the communities they serve. According to the most recent FDIC report concerning
branch deposits (June 1998), in four of the communities in which it has branches
(Acton, Frazier Park, Lake Los Angeles and Rosamond), Antelope is the only bank
and has a 100% share of the bank deposit market. In Lancaster and Palmdale, the
two largest markets it serves, Antelope has a market share of 24.4% and 15.0%,
respectively. Antelope's Wrightwood location has a 56.8% share of the deposit
market. Antelope's eighth location in Quartz Hill is a new branch that opened
for operation in June 1998. Eldorado intends to operate Antelope as a separate
subsidiary for the foreseeable future because of Antelope's strong name
recognition and customer acceptance in its local market, although Eldorado has
consolidated substantially all of Antelope's administrative functions with those
of Eldorado Bank.
 
    In connection with the Antelope acquisition, Eldorado issued approximately
2,780,000 shares of common stock to Antelope shareholders, based upon a fixed
exchange ratio of 3.625 shares of common stock for each share of Antelope common
stock. The Antelope acquisition was treated for accounting purposes as a pooling
of interests. The Company expects that during the quarter ending March 31, 1999
it will recognize approximately $800,000 of expenses, net of taxes, related to
the Antelope acquisition, including investment banking and professional fees and
severance costs.
 
    NAME CHANGE AND REVERSE STOCK SPLIT.  On August 28, 1998, Eldorado changed
its name from Commerce Security Bancorp, Inc. to Eldorado Bancshares, Inc. and
declared a one-for-two reverse stock split of the common stock effective
September 4, 1998.

    Presented below is a table showing Eldorado's capitalization and regulatory
capital ratios as of December 31, 1998. The column labeled "As Adjusted" gives
effect to the acquisition of Antelope as well as changes to the common stock
that will occur upon completion of the offering (see footnotes (1) and (2)
below). In addition, the column labeled "Pro Forma As Adjusted" gives effect to
(a) the sale by Eldorado of 2,000,000 shares of common stock offered hereby (at
a net offering price of $9.30 per share) and (b) the use of $12.0 million to
redeem all of the outstanding shares of 11% Series B Preferred Stock with an
aggregate liquidation value of $11.7 million.

(2) As reflected in Eldorado's Supplemental Consolidated Financial Statements,
    as of December 31, 1998, the common stock was divided into several classes
    consisting of (i) Special Common Stock, having a liquidation preference of
    $9.62 per share, (ii) voting common stock (designated as "Class B Common
    Stock"), and (iii) non-voting common stock (designated as "Class C Common
    Stock"). The holders of the Special Common Stock and Eldorado have agreed
    that immediately prior to the completion of the offering, the Special Common
    Stock will be converted into voting common stock. At such time, the common
    stock of Eldorado will consist solely of voting common stock (offered
    hereby) and non-voting common stock. The non-voting common stock may be held
    solely by two of Eldorado's principal shareholders, which for regulatory
    reasons under the BHC Act do not wish to own more than 9.9% of the voting
    common stock. Subject to compliance with applicable BHC Act provisions, the
    non-voting common stock may be converted into voting common stock at the
    election of the holder. With the exception of voting rights, voting common
    stock and non-voting common stock are identical in all respects. See
    "Principal and Selling Shareholders," "Certain Transactions" and
    "Description of Capital Stock."

                PRICE RANGE OF COMMON STOCK AND DIVIDEND POLICY
 
    Trading in the common stock has been extremely limited prior to the offering
and cannot be characterized as amounting to an established public trading
market. Eldorado has been quoted on the Nasdaq National Market since February 1,
1999 under the symbol "ELBI." Since that time, the high and low sales prices for
the common stock were $9.75 and $12 per share, respectively. On April 6, 1999,
the last reported sale price of the common stock was $9.75. Prior to its
quotation on the Nasdaq National Market, the common stock was registered with
the National Association of Securities Dealers ("NASD") and was traded only
over-the-counter (NASD/CBNK). See "Risk Factors--Limited prior market for common
stock and possible volatility of stock price." As of April 6, 1999, Eldorado had
approximately 1,185 shareholders of record.
 
    Eldorado has not declared or paid a cash dividend on the common stock and
does not currently plan to declare or pay a cash dividend on the common stock in
the foreseeable future. Dividends may be paid only out of legally available
funds as permitted by statute, subject to the discretion of Eldorado's Board of
Directors. See "Risk Factors--No present intention to pay dividends;
Restrictions on payment of dividends by the Banks to Eldorado; Prohibition on
dividends by Eldorado Bank to Eldorado without prior regulatory approval" and
"Supervision and Regulation--Regulatory Restrictions on Distribution to
Shareholders."
 
    Eldorado is a legal entity separate and distinct from the Banks.
Substantially all of Eldorado's revenues and cash flow, including funds
available for the payments of dividends and other operating expenses, will be
paid by dividends to Eldorado from the Banks. There are statutory and regulatory
limitations on the amount of dividends that may be paid to Eldorado by the
Banks. See "Risk Factors--No present intention to pay dividends; Restrictions on
payment of dividends by the Banks to Eldorado; Prohibition on dividends by
Eldorado Bank to Eldorado without prior regulatory approval" and "Supervision
and Regulation--Regulatory Restrictions on Distribution to Shareholders" for a

                                    BUSINESS
 
OVERVIEW
 
    Through its two operating subsidiaries, Eldorado Bank and Antelope Valley
Bank, the Company offers a broad range of commercial banking products and
services to small and medium-sized businesses and retail customers from 25 full
service offices located primarily in Southern California and the Sacramento area
of Northern California. Eldorado Bank also operates eight loan production
offices, four of which are located in California and four of which are located
in other western states. See "-- Market." Our products include commercial,
consumer and real estate loans, a broad range of deposit products and other
non-deposit banking services. In addition, we augment our traditional banking
products and services with specialized products including
 
    - Small Business Administration ("SBA") loans,
 
    - residential mortgage loans originated through eight loan production
      offices and a regional network of wholesale brokers for resale into the
      secondary market,
 
    - equipment leases to small and medium-sized businesses that are originated
      through a national network of wholesale brokers, and
 
    - loans to finance the acquisition of new and used automobiles that are
      originated through approximately 60 automobile dealers located in Southern
      California.
 
    Eldorado Bank and Antelope Valley Bank are incorporated under the laws of
the State of California and are licensed by the California Department of
Financial Institutions ("DFI"). Eldorado Bank is a member of the Federal Reserve
System. Antelope Valley Bank is not a member, and therefore is regulated at the
federal level by the Federal Deposit Insurance Corporation ("FDIC"). The Banks'
deposits are insured up to applicable limits by the FDIC. See "Supervision and
Regulation."
 
    The financial information presented in this prospectus treats the
acquisition of Antelope Valley Bank as if it had been completed prior to the
periods presented herein and should be read in conjunction with our Supplemental
Consolidated Financial Statements and Notes thereto included elsewhere in this
prospectus.
 
STRATEGIC PLAN
 
    The key elements of our strategic plan have been and continue to be the
establishment and enhancement of an attractive community banking franchise
through the acquisition of community banks primarily, but not exclusively, in
and around our Southern California base, the improvement of core profitability
and the maintenance of a strong balance sheet. Since 1995, we have acquired four
community banks with combined assets of approximately $1 billion. See "Recent
Developments" and "-- Prior Acquisitions."
 
        BUILDING AND ENHANCING AN ATTRACTIVE COMMUNITY BANKING FRANCHISE. We are
    continually engaged in the identification and evaluation of potential
    acquisitions of community banks in California. We focus primarily on
    community banks that have underperformed relative to their peers but have
    strong lending franchises, niche business lines or low cost deposits that
    would complement our existing operations and branch network and also provide
    opportunities for cost savings through branch overlap and back-office
    consolidation. In particular, we seek to acquire and develop both
    traditional and non-traditional community banking businesses that provide
    opportunities for multiple relationships with our customers. As an integral
    part of this strategy, we emphasize building a solid management team through
    a combination of senior officers retained from acquired banks and
    experienced specialists hired to enhance our competency in various areas,
    such as mortgage banking and equipment leasing. Consistent with our
    acquisition strategy, we recently completed the acquisition of Antelope
    Valley Bank. We routinely review suitable strategic acquisition
    opportunities, which if consummated, may
 
                                       23
<PAGE>
    constitute a material acquisition for Eldorado. Discussions at various
    stages with respect to such transactions are ongoing as of the date of this
    prospectus. Such discussions include one or more proposals as to which
    Eldorado is awaiting a response from the board of directors of the potential
    transaction partner. Eldorado believes, however, that as of the date of this
    prospectus it is not probable that we will enter into an agreement with
    respect to any particular transaction. See "Recent Developments."
 
        IMPROVING CORE PROFITABILITY. Our strategy to increase profitability is
    premised on (i) increasing the sources and volume of fee income, including
    fees derived from originating and servicing SBA loans, selling and servicing
    equipment leases, and originating and selling residential mortgage loans,
    (ii) expanding and diversifying our base of relatively low cost funds, (iii)
    utilizing our asset generation capability to increase the volume of
    commercial loans and leases that we retain in our portfolio, particularly
    SBA loans, equipment leases and commercial loans to our small business
    customers, and (iv) actively seeking to improve operating efficiencies.
 
        MAINTAINING A STRONG BALANCE SHEET. We seek to maintain a strong balance
    sheet by managing the risk of credit-related losses and by striving to
    maintain a capital base sufficient to support our strategic plan. We seek to
    improve the asset quality of the banks we acquire by implementing
    underwriting standards in the acquired banks' loan and lease origination
    programs that place greater emphasis on cash flow than collateral coverage
    as the primary source of repayment on its loans. See "-- Underwriting and
    Credit Administration," below. To maintain a capital base sufficient to
    support our existing businesses and to permit us to continue to expand
    through acquisitions, our objective is to meet the "well capitalized"
    regulatory standards. Giving effect to the offering and the expected use of
    proceeds therefrom, at December 31, 1998, we would have been well
    capitalized for regulatory purposes, with Tier 1 and Total Risk-Weighted
    Ratios (as defined herein) of 9.44% and 10.46% and a Tier 1 Leverage Ratio
    (as defined herein) of 6.87%. See "Supervision and Regulation -- Capital
    Adequacy Requirements."
 
    The principal reason for the offering is to create an active trading market
for our common stock. We believe that the existence of such a market will
increase our ability to complete acquisitions on a stock-for-stock basis.
Although we expect to continue to consider cash acquisitions, we believe that
the boards of directors and shareholders of many prospective acquisition
candidates prefer stock acquisitions, because the shareholders who receive stock
are allowed to retain an equity interest in the combined company and to defer
recognition of federal income tax. We can provide no assurance, however, that an
active trading market for our common stock will develop after the offering or
that, even if such a market does develop, we will be able to acquire or will
determine that it is in our best interests to acquire businesses in stock-for-
stock transactions.
 
PRIOR ACQUISITIONS
 
    Prior to September 1995, the Company's predecessor, SDN Bancorp, Inc.
("SDN"), owned a single bank -- San Dieguito National Bank ("San Dieguito") --
which had $56 million in assets. San Dieguito was then categorized as
"critically undercapitalized" by federal regulators. In September 1995, SDN and
San Dieguito were recapitalized by Dartmouth Capital Group, L.P. ("DCG"), a bank
holding company organized by Mr. Keller. Following that recapitalization, Mr.
Keller assumed control of the Company, installed new management and began
implementing policies to improve asset quality and operating performance.
 
    Since September 1995, Eldorado has acquired four banks in California with
combined assets of approximately $1 billion. The following table summarizes
certain data regarding those acquisitions,
 
                                       24

including the asset size of the acquired bank as of the end of the quarter
immediately preceding the acquisition:

</TABLE>
 
    Other than the Antelope transaction, each acquisition was accounted for
using the purchase method of accounting for business combinations. Therefore,
the operating results of those banks are reflected in our financial statements
only from the date of acquisition. Consequently, our historical operating
results prior to June 1997 are of limited relevance in evaluating our historical
financial performance or predicting our future operating results.
 
    Within the relatively recent past, Commerce Security Bank ("CSB"), Liberty
National Bank ("Liberty") and San Dieguito were adversely affected by a variety
of factors, including high levels of nonperforming assets, reliance on high-cost
brokered deposits and excessive overhead costs. The high levels of nonperforming
assets and related overhead costs were partly attributable to adverse economic
conditions, including declining real estate values, that California experienced
during the early to mid-1990s. See "Risk Factors -- Prior losses at predecessor
subsidiary banks." As a consequence of their poor financial performance, each of
Liberty, San Dieguito and CSB was required to enter into a memorandum of
understanding with its supervising regulators. Those memoranda of understanding
were subsequently terminated contemporaneously with or, in Liberty's case, prior
to Mr. Keller's assumption of managerial control. See "Risk Factors --
Supervision and regulation -- Our banks operate in a highly regulated
environment."
 
    Following each acquisition, we implemented various elements of the strategic
plan described above. See "-- Strategic Plan." As a result of those efforts,
together with a favorable economic climate in California, our ratio of
nonperforming assets to total assets improved from 2.8% at December 31, 1996 (on
a pro forma basis giving effect to the acquisition of Eldorado Bancorp) to 0.9%
at December 31, 1998, and our efficiency ratio improved from 80.0% for the
twelve months ended December 31, 1996 to 73.6% for the twelve months ended
December 31, 1998. Additionally, we were able to reduce reliance on high-cost
brokered deposits by utilizing excess liquidity at Eldorado Bank to fund loans
and leases generated by the other subsidiary banks.
 
    Effective June 30, 1997, the Company consolidated into Eldorado Bank the
respective operations of CSB, Liberty and San Dieguito, although Eldorado Bank
continues to operate under the name "Commerce Security Bank" in the Sacramento
area because of another bank's competing claim to the tradename "Eldorado Bank."
See "-- Market."
 
MARKET
 
    Eldorado operates primarily in Southern California and the Sacramento area
of Northern California. Our executive office is located in Laguna Hills, a
residential community in southern Orange County, approximately 50 miles south of
Los Angeles. Eldorado currently operates a total of 24 full-service banking
offices in Southern California, covering a geographic market ranging from the
north coastal area of San Diego County in the south, to Kern County and the
northern border of Los Angeles County in the north, and to San Bernardino and
Riverside Counties in the east. The counties of Orange, Los Angeles, San
Bernardino and Riverside are located in the Los Angeles-Riverside-Orange County
Metropolitan Statistical Area ("MSA"), which is the second most populous MSA in
the United States, with a population of 15.5 million in 1996, according to the
most currently available estimate published by the U.S. Bureau of the Census.
Eldorado also operates a mortgage loan production office in San Diego,
California.
 
                                       25
<PAGE>
    In Northern California, Eldorado operates one full-service banking office,
located in Sacramento, and three mortgage loan production offices located in
Sacramento, Stockton and Walnut Creek. Sacramento, the capital of California, is
located in the Sacramento MSA, which had a population of 1.5 million in 1996,
according to an estimate published by the U.S. Bureau of the Census. Eldorado
also operates one SBA loan production office in Orinda, California, which is
located east of San Francisco.
 
    Outside of California, Eldorado currently has mortgage loan production
offices in Bellevue, Washington; Las Vegas, Nevada; Phoenix, Arizona and
Portland, Oregon.
 
PRODUCTS AND SERVICES
 
    The Company markets its products and services through four divisions:
 
    - COMMUNITY BANKING DIVISION -- focusing primarily on small and medium-sized
      businesses located in the Company's California markets. Products include
      commercial, consumer and real estate loans (with a particular emphasis on
      the origination and servicing of SBA loans), and a broad range of deposit
      products and other non-deposit banking services.
 
    - MORTGAGE BANKING DIVISION -- originating residential mortgage loans in
      California, Arizona, Nevada and Oregon through eight loan production
      offices and a network of wholesale brokers for sale in the secondary
      market.
 
    - EQUIPMENT LEASING DIVISION -- generating equipment leases primarily
      through wholesale brokers located throughout the United States, servicing
      those leases and from time to time selling blocks of leases to other
      institutions.
 
    - AUTOMOBILE LENDING DIVISION -- purchasing loans to finance the purchase of
      new and used automobiles originated by approximately 60 automobile dealers
      located in Southern California.
 
The Company's marketing strategy seeks to exploit cross-selling opportunities by
emphasizing the complementary nature of its products and services, particularly
for small to medium-sized businesses, which the Company defines as businesses
with annual revenue up to $50 million. The Company is also seeking to improve
operating efficiencies among its divisions by establishing lease and mortgage
loan offices in several of the locations previously used exclusively as branches
or loan production offices. In addition, the Company plans to house SBA loan
production officers in several of its established mortgage origination offices.
Each of the Company's divisions is described in more detail below.
 
    COMMUNITY BANKING DIVISION.  The Community Banking Division provides a broad
range of banking products and services to small and medium-sized businesses and
retail customers, including commercial, real estate and consumer loans, checking
and savings products and non-depository services.
 
    At December 31, 1998, management estimates that approximately 80% of the
Company's loans and leases held for investment were loans to businesses. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations." For regulatory and financial reporting purposes, the Company
categorizes commercial loans that are secured in whole or part by real estate as
commercial real estate loans. Consequently, at December 31, 1998, commercial
real estate loans constituted 30.4% of the Company's loans and leases held for
investment. The Company believes such categorization overstates the Company's
emphasis on real estate lending, because, for example, all SBA loans are secured
by real estate and thus categorized as commercial real estate loans. The
following table sets forth the distribution as of December 31, 1998 of the
Company's SBA loans, other commercial real estate loans and commercial loans

    The origination and servicing of SBA loans are important elements of the
Community Banking Division's business. For the year ended December 31, 1998, the
Company originated $51.9 million of SBA loans. Revenue attributable to the
Company's SBA lending activities was $14.4 million for the year ended December
31, 1998, constituting 12.4% of its total interest and noninterest income for
that period. In the Company's experience, the volume of SBA loan originations
generally is less in the first quarter of the year and higher in the fourth
quarter.
 
    The Company originates two types of loans under SBA programs. The majority
of SBA loans that the Company originates are guaranteed by the United States
Government to the extent of 75% to 90% of the principal and interest due on such
loans ("SBA 7(a)" loans). The Company also originates SBA loans in which the
Company takes a first trust deed (a senior security position which is generally
sold by the Company) and another unrelated entity assumes a second trust deed (a
subordinated security position) that is guaranteed by the SBA ("SBA 504" loans).
Generally, the Company sells the government guaranteed portion of the SBA 7(a)
loans to participants in the secondary market and retains servicing
responsibilities and the unguaranteed portion of the loans. The government
guaranteed portion of the SBA 7(a) loans are sold at a premium, a portion of
which is immediately recognized as income. The balance of the premium,
representing estimated servicing fees, is treated as a yield adjustment on the
portion of the SBA 7(a) loan retained by the Company and is capitalized and
recognized as income over the estimated life of the loan. The Company had a
total of $93.7 million of SBA loans in its portfolio at December 31, 1998,
comprised of $69.2 million of the unguaranteed portions of the SBA 7(a) loans
being serviced by the Company and $24.5 million of SBA 504 loans. The total SBA
7(a) loan portfolio serviced by the Company at December 31, 1998 was $250.0
million, all of which had been originated by the Company.
 
    Since 1994, Eldorado Bank has qualified as a "Preferred Lender" under the
SBA's programs, allowing it to originate SBA loans based on its own underwriting
decisions and without prior approval of the SBA. The Company believes that its
status as a Preferred Lender gives it a competitive advantage relative to other
non-Preferred SBA originators by allowing the Company to process such loans on
an expedited basis. For the SBA's fiscal year ended September 30, 1998, the
Company originated $16.2 million, or approximately 60% of its SBA 7(a) loans,
within the SBA district consisting of the counties of Orange, Riverside and San
Bernardino. For that period, the Company produced the 6th greatest dollar volume
of SBA loans in that district by all SBA lenders and the 3rd largest dollar
volume of SBA 7(a) loans produced in that district by SBA originating banks. By
comparison, the leading nonbank and bank SBA lenders headquartered in that
district originated $65.0 million and $29.9 million of SBA 7(a) loans,
respectively, which the Company believes reflects the fragmented and highly
competitive market for SBA loans in Southern
 
                                       27
<PAGE>
California. The Company believes that all of the leading SBA originators in the
Company's principal market are Preferred Lenders.
 
    Historically, the Company has made SBA loans primarily to businesses located
in California through origination from its Southern California branches as well
as from the Company's SBA loan production office located in Orinda, California.
Subject to receipt of SBA approval, which the Company expects will be received,
the Company intends to expand its SBA market area during the next 12 months by
hiring SBA loan originators based in or near Phoenix, Arizona; Portland, Oregon
and Bellevue, Washington. The Company intends to place those originators in the
Company's existing loan production facilities for the Mortgage Banking Division
located in those areas.
 
    With respect to deposit products and related services, the Company believes
the Community Banking Division has a competitive advantage as a result of
certain deposit accounting services that were developed at CSB specifically for
title and escrow companies. As a result of those services, which include
specialized sub-accounting, reconciliation and reporting features, a significant
percentage of the Company's deposit liabilities are obtained from title and
escrow companies (collectively, "Title and Escrow Deposits"). For the year ended
December 31, 1998, Title and Escrow Deposits averaged $187.0 million,
representing 18.2% of the Company's total average deposits for that period.
Actual balances of Title and Escrow Deposits tend to vary widely during a month,
with the highest balances usually occurring at the end of the month when
residential real estate closings are generally scheduled to occur. Title and
Escrow Deposits are also subject to seasonal fluctuations, tending to decrease
during those seasons when the volume of residential real estate transactions is
lower. Title and Escrow Deposits at December 31, 1998 totaled $278.7 million,
constituting 22.8% of the Company's total deposits at that date. One company
controlled Title and Escrow Deposits that represented 15.2% of the Company's
total average deposits for the year ended December 31, 1998 and 20.2% of the
Company's total deposits at December 31, 1998.
 
    The Company considers Title and Escrow Deposits to be volatile because of
the fluctuation in deposit amounts and the concentration of control over those
deposits with a limited number of customers. The Company believes, however, that
its relationships with its principal Title and Escrow Deposit customers and its
specialized deposit services partially mitigate the risk that such customers may
terminate or significantly reduce their deposits with the Company. See "Risk
Factors -- Reliance on potentially volatile title and escrow deposits to fund
short-term assets." As a consequence of that potential volatility, the Company
utilizes Title and Escrow Deposits solely to fund short-term assets, primarily
consisting of residential mortgage loans held for sale, which are generally sold
within 30 days after such mortgage loans are funded. See "-- Products and
Services -- Mortgage Banking Division." If a substantial portion of the Title
and Escrow Deposits were withdrawn suddenly, the Company believes that it has
sufficient alternative sources of liquidity to fund its mortgage pipeline during
a transition period. To reduce its concentration of Title and Escrow Deposits,
since December 31, 1998, the Company has generally limited the balance of Title
and Escrow Deposits that it will permit any one depositor to maintain to
approximately $100 million. See "Risk Factors -- Reliance on potentially
volatile title and escrow deposits to fund short-term assets" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
    The Company's expertise in servicing Title and Escrow Deposits has also
enabled it to attract deposits from homeowners' associations, property managers
and similar customers. The services provided to those customers include (i)
lockbox deposit arrangements, (ii) sub-account reconciliation and reporting,
(iii) electronic payment and remittance processing through the Automated
Clearing House or ACH Network and (iv) electronic balance reporting. Those
specialized payment handling systems also complement the Company's other
traditional cash management products.
 
    Historically, the relationships with Title and Escrow Deposit customers, as
well as the relationships with other deposit customers utilizing the Company's
sub-accounting systems, have been managed by the Company's Sacramento branch.
The Company is actively seeking, however, to cross-sell those services to
customers of its Southern California branches.

    MORTGAGE BANKING DIVISION.  The Company entered the mortgage banking
business upon the acquisition of CSB in September 1996. CSB had been engaged in
the mortgage business since 1988. The Company originates and sells first and
second lien mortgage loans secured by single family residences. As a matter of
normal practice, the Company sells to the secondary market all of the mortgage
loans that it originates. The Mortgage Banking Division's operating results can
be and have been affected materially by changes in interest rates, and in the
levels of new home construction and existing home sales. See "Risk Factors --
Changes in interest rates may adversely affect our business."
 
    The Company originates mortgage loans through two primary sources: (i) the
wholesale market, which represents loans generated through a network of mortgage
brokers approved by the Company, and (ii) the retail market, which represents
loans generated by eight loan production offices staffed with commission-based
loan officers who solicit loans directly from real estate brokers and home
builders and on personal referral. All loans originated from those two sources
are underwritten and closed by the Company. For the year ended December 31,
1998, approximately 88% of the Company's residential mortgage loans were
originated on a wholesale basis, and during that period, the top ten brokers
generated 34.8% of such loans.
 
    The Company originates primarily fixed-rate mortgage loan products under a
variety of programs including (i) conventional fixed-rate mortgage loans under
programs offered by the Federal Home Loan Mortgage Corporation ("Freddie Mac")
or the Federal National Mortgage Association ("Fannie Mae"), (ii) so-called
"nonconforming" mortgage loans that do not meet Freddie Mac or Fannie Mae
criteria, including "jumbo loans" that exceed the maximum principal amount under
those programs, which the Company underwrites to satisfy the individual
guidelines of the private investors to which those loans are sold in the
ordinary course, and (iii) mortgage loans insured by the Federal Housing
Administration ("FHA loans") and mortgage loans guaranteed by the Veterans
Administration ("VA loans"). FHA loans and VA loans are underwritten to enable
them to be pooled as loans offered by the Government National Mortgage
Association ("Ginnie Mae loans"). In addition, beginning in 1998 the Company
extended its range of products to include certain types of subprime loans (which
are sometimes referred to as "B" grade loans). During the three months ended
December 31, 1998, subprime loans constituted less than 1.0% of all mortgage
loans originated by the Company during that period. The Company is evaluating
the extent to which it wants to devote resources to the subprime product. The
Company does not expect that subprime loans will constitute more than 5% of its
total mortgage loan origination volume.
 
    The following table sets forth the volume of mortgages funded by the Company
during the last five consecutive fiscal quarters ended December 31, 1998.

    The Company has historically sold conforming Freddie Mac and Fannie Mae
loans under private sale agreements to conduits such as Countrywide Home Loans.
FHA and VA loans that the Company originates either are sold individually to
private conduits or are bundled and sold as Ginnie Mae loans to private
investors. In addition, since July 1998, the Company has been approved to sell
Ginnie Mae-eligible loans directly to Freddie Mac and Fannie Mae.
 
    The Company also sells the right to service such mortgage loans, which
includes the collection and remittance of principal and interest payments. Such
servicing rights either are sold to the purchaser of the loan or, in the case of
Ginnie Mae loans, from time to time are aggregated and sold in bulk at least
quarterly, which the Company believes increases the value of those servicing
rights. The purchasers of mortgage loans or servicing rights do not have
recourse against the Company for the payment defaults of the borrowers, except
for (i) customary recourse if the borrower fails to make the first payment due
under the loan and (ii) recourse obligations that were incurred in connection
with CSB's bulk sales of servicing for VA loans that were effected prior to the
Company's acquisition of CSB. Such recourse exposure for VA loans expired in
November 1998. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
    The Company relies on various short-term funding sources, including Title
and Escrow Deposits and lines of credit with various financial institution, to
provide liquidity to its Mortgage Banking Division between the time when the
Division originates a mortgage loan and the time when such loan is sold in the
secondary market. See "-- Products and Services -- Community Banking Division"
and "Risk Factors -- Reliance on potentially volatile title and escrow deposits
to fund short-term assets."
 
    "Forward commitments" and "put options" on mortgage-backed securities are
used to reduce or hedge interest rate risk on a portion of loans held for sale
and on certain loans anticipated to fund. Forward commitments to sell and put
options on mortgage-backed securities that hedge anticipated loan funding are
off-balance sheet items and not reflected in the Company's Supplemental
Consolidated Statement of Financial Condition. The aggregate outstanding
"forward commitments" and "put options" at December 31, 1998 were $94.0 million
and $76.0 million. It should be noted, however, that because those instruments
may not respond to changes in interest rates to the same degree as the mortgage
loan pipeline being hedged, some interest rate risks remain even in a fully
hedged portfolio. For example, during the quarter ended December 31, 1998,
Eldorado incurred a loss of $1.1 million on hedging activities primarily because
of an unexpected change in the correlation between the value of the mortgage
loans in its pipeline and mortgage-backed securities used for hedging. See "Risk
Factors -- Changes in interest rates may adversely affect our business."
 
    Although the Mortgage Banking Division historically provided a substantial
amount of CSB's earnings, the Division generated losses during each month of
1996 and during nine out of 12 months of 1997. Since the Company acquired CSB in
September 1996, the Company has undertaken a variety of measures to improve the
Division's operating results, including the renegotiation of the terms under
which the Company sells loans to the secondary market, the packaging of Ginnie
Mae loans, the elimination of certain recourse liability in connection with the
sale of VA loan servicing rights, and the achievement of various operational
efficiencies. In addition, the Company has made several managerial changes at
the Mortgage Banking Division, the most significant of which was the February
1998 hiring of William D. Rast to serve as its Executive Vice President and head
of the Division. Mr. Rast has approximately 21 years of experience in mortgage
banking, including four years as President and Chief Operating Officer of
Hamilton Financial Services Corp., a financial services company that focused
primarily on mortgage lending, and 10 years with First California Mortgage,
where his last position was Senior Vice President responsible for retail and
wholesale production. See "Management." Since joining the Company, Mr. Rast and
his management team have overseen the implementation of several initiatives
designed to improve the Mortgage Banking Division's operations. Among other
things, the Company has (i) enhanced the Mortgage Banking Division's network of
brokers by adding additional brokers with whom Mr. Rast previously had developed
relationships and terminating those brokers who were not reliable sources of
originations,
 
                                       30
<PAGE>
and (ii) actively managed the duration of time between the Company's funding of
a mortgage loan and the time when that loan may be sold into the secondary
market.
 
    The Company believes that those initiatives, combined with a favorable
refinancing market in 1998, have substantially improved the Mortgage Banking
Division's performance. For the year ended December 31, 1998, the Mortgage
Banking Division originated $1.8 billion of mortgage loans as compared to $889.2
million for the year ended December 31, 1997. The Division's pre-tax
profitability -- measured by the Company as revenue less direct expenses and the
cost of funds provided by the Community Banking Division and other sources --
increased by $5.7 million to $3.1 million for the year ended December 31, 1998
from a loss of $2.6 million for the year ended December 31, 1997. The Company
has also used the increase in mortgage origination volume to manage its level of
earning assets by increasing from time to time the duration that it will hold
mortgage loans prior to selling such loans into the secondary market. Although
the Company believes that it has hedged such mortgage loans to substantially
mitigate the interest rate risk associated with the longer holding period, some
interest rate risk remains. See "Risk Factors -- Changes in interest rates may
adversely affect our business."
 
    During the next 12 months, the Mortgage Banking Division intends to continue
to improve its origination capability by, among other things, (i) further
refining its network of wholesale brokers, (ii) more actively cross-selling its
products to the Company's retail customers, and (iii) enhancing the automation
of the application and approval process including the implementation of
electronic application and delivery systems. The Company expects that the
Mortgage Banking Division's cross-selling efforts will focus primarily on
developing relationships with internal and external referral sources in the
Company's Southern California market. Among other things, the Mortgage Banking
Division intends to place mortgage loan officers in the Company's branches.
Beginning in 1998, mortgage loan officers were placed in its branches in
Carlsbad (San Diego County), Huntington Beach (Orange County) and San Bernardino
(San Bernardino County).
 
    EQUIPMENT LEASING DIVISION.  The Company entered the leasing business upon
the acquisition of CSB in September 1996. CSB had been engaged in leasing since
1990, focusing primarily on acquiring leases of equipment to small businesses
with an average lease size of less than $50,000. Currently, the production of
new leases is derived primarily from the wholesale sector through a network of
brokers located throughout the United States, although a majority of the
Equipment Leasing Division's leases are made to borrowers located in the
mid-western and western states. The Company makes no consumer leases and leases
automobiles and other vehicles only to businesses. The Company seeks to limit
the residual risk with respect to the collateral it leases by purchasing leases
that permit the lessee to acquire the equipment for a nominal purchase price at
the end of the lease term or by stipulating that the originating broker will
retain the residual risk. The Banks' largest concentration of leases to a single
borrower (and related interests) at December 31, 1998 amounted to $342,000.
Historically, the Company has generally retained for investment the majority of
leases that it purchases, although in 1997, the Company sold $24.8 million of
leases to other banks while retaining the right to service those leases. The
Company expects to conduct similar sales of leases in the future to avoid an
excess concentration of leases as a percentage of total portfolio loans and
leases. The Company currently expects that its lease portfolio will not
materially exceed 15% of the Company's portfolio loans and leases.

investment. The following table sets forth the collateral concentrations of the
Company's leases at December 31, 1998.

(1) No category of collateral concentration included in Other is in excess of
    2.3%.
 
    Following the CSB acquisition, the Company made a strategic decision to
increase the resources devoted to the Equipment Leasing Division. Among other
things, the Company has centralized the underwriting decisions for leases,
thereby eliminating the salesperson's involvement in the underwriting decision.
In addition, the Company has also increased the aggregate volume and average
size of the Company's leases and diversified the type and location of the
underlying lease collateral, partly as a result of hiring full-time sales
representatives located in or near Boston, Massachusetts; Dallas, Texas and
Carlsbad, California.
 
    The Company believes that those initiatives have substantially improved the
Equipment Leasing Division's performance. For the year ended December 31, 1998,
the Company originated $69.3 million of leases with an average lease size of
$37,700, as compared to $32.2 million of leases with an average lease size of
$24,700 for the year ended December 31, 1997. The Division's pre-tax
profitability -- measured by the Company as revenue (excluding gain on sale of
leases) less direct expenses and the cost of funds provided by the Community
Banking Division and other sources -- increased by $1.0 million to $1.9 million
for the year ended December 31, 1998 from $882,000 for the year ended December
31, 1997.
 
    During the next 12 months, the Equipment Leasing Division intends to
continue to increase its origination volume by focusing on improving the overall
quality of the Company's network of wholesale brokers and by expanding the
number of full-time representatives. In February 1999, the Company hired Ronald
Wagner as Executive Vice President for the Equipment Leasing Division. Mr.
Wagner has approximately 20 years of experience in the leasing business,
including most recently as Senior Vice President in charge of production for
Imperial Business Credit, Inc., a subsidiary of Imperial Credit Industries,
Inc., a publicly traded financial services company. See "Management."
 
    AUTOMOBILE LENDING DIVISION.  In January 1999, the Company expanded its
indirect automobile lending activity with its acquisition of Antelope Valley
Bank. Antelope generates interest-earning assets primarily through the
origination of indirect automobile loans (also known as dealer loans). Dealer
loans are originated by automobile dealers and sold to the Company at a discount
to the note rate. The present value of the difference between the discounted
rate to the Company and the note rate is paid to the dealer and capitalized and
amortized by the Company over the effective life of the loan using a formula
that approximates the interest method. Antelope has been active in the
origination of dealer loans since 1980.
 
    Following the Antelope acquisition, the Company consolidated the dealer loan
programs of Eldorado Bank with the existing structure at Antelope. The Company
generates dealer loans through approximately 60 dealers spread throughout
Southern California with a concentration in north Los Angeles County. Fifteen of
those dealers accounted for approximately 80% of the loans funded by the Company
during the
 
                                       32
<PAGE>
year ended December 31, 1998, with the largest single relationship accounting
for approximately 21.6% of such loans. The average length of the Company's
relationship with such 15 dealers is approximately eight years and ranges from
two to 17 years. Dealer relationships are evaluated by management from time to
time to assess the level and pattern of losses on the dealer loans originated by
a dealer and to examine the current financial information and credit reports of
the dealers themselves.
 
    Each loan received from a dealer is individually underwritten by the Company
using a methodology developed by Antelope, which includes the review of an
applicant's credit report and confirmation of information provided in the
financing application. The average dealer loan amount purchased by the Company
is approximately $13,000, and the majority of such loans were originated to
finance the purchase of used automobiles. The finance market for new automobile
loans is very competitive with the largest competitors being the finance
affiliates of major automobile manufacturers, including Ford Motor Credit,
General Motors Acceptance Corp., and Chrysler Financial. At December 31, 1998,
the Company held $104.0 million of dealer loans, constituting 11.5% of the
Company's gross portfolio loans and leases.
 
    The following table sets forth the volume of dealer loans funded by the
Company during the last five fiscal quarters ended December 31, 1998.

    During the next 12 months, the Automobile Lending Division intends to
continue to increase its origination volume by developing additional dealer
relationships further south into Los Angeles and Orange Counties where,
according to the California Motor Vehicle Dealers Association, there are
approximately 370 automobile dealership franchises.
 
UNDERWRITING AND CREDIT ADMINISTRATION
 
    UNDERWRITING.  Although the Banks accept applications for various types of
commercial and consumer loans at all of their branches, all loans are subject to
centralized underwriting and processing, with the exception of commercial loans
less than $100,000. Residential mortgage loans may also be approved for sale
into the secondary market at one of two loan production offices in Northern
California.
 
    Eldorado Bank generally does not make individual loans larger than $8.0
million, although its applicable legal lending limit is substantially higher
(for secured loans, 25% of Eldorado Bank's equity plus its allowance for loan
and lease losses, or $21.5 million at December 31, 1998). Lending authorities
range from $2,500 to $100,000 for most loan officers and from $250,000 to
$300,000 for regional vice presidents. Authorization limits for such officers
are set by Eldorado Bank's Chief Credit Officer based upon area of
responsibility and prior lending experience and are ratified by the Eldorado
Bank Board of Directors. The
 
                                       33
<PAGE>
head of the Commercial Banking Division has commercial lending authority of
$500,000, while the head of the Community Banking Division has commercial
authority of $250,000 and SBA authority of $1.0 million. Eldorado Bank's Chief
Credit Officer has the authority to approve loans up to $1.0 million. Loans in
excess of $1.0 million but less than $2.0 million must be approved by Eldorado
Bank's Chief Credit Officer and Eldorado Bank's President, and loans in excess
of $2.0 million but less than $4.0 million must also be approved by an Officer
Loan Committee, of which the Chief Credit Officer and Eldorado Bank's President
are members. Loans in excess of $4.0 million but less than $8.0 million must
also be approved by the Loan Committee of Eldorado Bank's Board of Directors,
and loans in excess of $8.0 million must also be approved by the Board of
Directors of Eldorado Bank. As of December 31, 1998, 37 borrowers had total
obligations (including loans to related interests) to Eldorado Bank in excess of
$2.0 million, representing $81.7 million or 15.8% of Eldorado Bank's total
portfolio loans and leases at that date. At December 31, 1998, the Company's
largest concentration of loans to a single borrower (and related interests)
totaled $6.8 million. As of the date of this prospectus, all outstanding loans
in excess of $2.0 million are performing and are secured primarily by real
estate located in Southern California.
 
    Antelope generally does not make individual loans larger than $1.0 million,
although its applicable legal lending limit is substantially higher (for secured
loans, 25% of Antelope's equity plus its allowance for loan and lease losses, or
$5.8 million at December 31, 1998). Lending authorities for senior loan officers
at Antelope range from $2,500 to $100,000. Authorization limits for such
officers are set by Antelope's Chief Credit Officer based upon area of
responsibility and prior lending experience and are ratified by the Antelope
Board of Directors. The Company's President, who also serves as Antelope's
Chairman and Chief Executive Officer, has the authority to approve loans up to
$500,000, and Antelope's President and its Chief Credit Officer each have the
authority to approve loans up to $100,000 individually and jointly up to
$300,000. Loans in excess of $500,000 must be approved by the Antelope Board of
Directors. As of December 31, 1998, Antelope's 10 largest borrowing
relationships had total obligations (including loans to related interests) to
Antelope representing $14.5 million or 10.6% of Antelope's total loans and
leases at that date. At December 31, 1998, Antelope's largest concentration of
loans to a single borrower (and related interests) totaled $3.5 million. As of
the date of this prospectus, all outstanding loans to Antelope's 10 largest
borrowers are performing and are secured primarily by real estate located in
Southern California.
 
    The Company's commercial loans are generally underwritten in the Company's
primary market area on the basis of the borrower's ability to service such debt
from income. As a general practice, the Company takes as collateral a lien on
any available real estate, equipment or other assets and obtains a personal
guaranty. Working capital loans are primarily collateralized by short-term
assets and term loans are primarily collateralized by long-term assets.
 
    In addition to commercial loans secured by real estate, the Company makes
commercial mortgage loans to finance the purchase of owner-occupied real
property, which generally consists of real estate on which structures have
already been completed. The Company's commercial mortgage loans are secured by
first liens on real estate, typically have variable interest rates and
generallly amortize over a 20-year period with balloon payments due at the end
of five years. In underwriting commercial mortgage loans, consideration is given
to the property's operating history, future operating projections, current and
projected occupancy, location and physical condition. The underwriting analysis
also includes credit checks, appraisals and a review of the financial condition
of the borrower.
 
    The Company makes loans to finance the construction of residential
properties, the majority of which are owner-occupied and, to a limited extent,
owner-occupied nonresidential properties. Construction loans generally are
secured by first liens on real estate. The Company conducts periodic
inspections, either directly or through an agent, prior to approval of periodic
draws on these loans. Underwriting guidelines similar to those described above
are also used in the Company's construction lending activities.
 
                                       34
<PAGE>
    Consumer loans made by the Company include home improvement loans,
automobile loans, recreational vehicle loans, boat loans, personal loans
(collateralized and uncollateralized) and deposit account collateralized loans.
The terms of these loans typically range from 12 to 84 months and vary based
upon the nature of collateral and size of loan.
 
    The head of the Equipment Leasing Division has authority to approve leases
up to $150,000 and two other officers have authorization levels of $75,000 and
$50,000, respectively. Leases in excess of $150,000 must also be approved by the
Company's Chief Credit Officer. The Company generally does not make leases in
excess of $150,000, and since the Company's acquisition of CSB, the Company has
not made a lease in excess of $500,000.
 
    Senior officers of the Mortgage Banking Division have authority to approve
funding of residential loans for sale into the secondary market up to $2.0
million. Residential loans in excess of $2.0 million are subject to the same
approval criteria required for commercial loans.
 
    CREDIT ADMINISTRATION AND NONPERFORMING ASSETS.  The Company has several
procedures in place to assist it in maintaining the overall quality of its loan
and lease portfolio, as described below. There can be no assurance, however,
that the Company's loan and lease portfolio will not become subject to
increasing pressures from deteriorating borrower credit due to general economic
conditions.
 
    With the exception of the Equipment Leasing Division, which administers and
collects the leases that it services, the Company has a centralized Credit
Administration Department. The Department is responsible for supervising the
Company's loan review function and its Special Asset Group, which focuses
exclusively on the collection or other resolution of nonaccrual loans and OREO.
The Company's loan review function evaluates additional loans that are potential
problem loans as to risk exposure in determining the adequacy of the allowance
for loan losses. The Company obtains updated appraisals from time to time on
loans secured by real estate, particularly those categorized as nonperforming
loans and potential problem loans. In instances where updated appraisals reflect
reduced collateral values, an evaluation of the borrower's overall financial
condition is made to determine the need, if any, for possible writedowns or
appropriate additions to the allowance for loan losses.
 
    The Company generally places a loan on nonaccrual status and ceases accruing
interest when loan payment performance is deemed unsatisfactory. All loans past
due 90 days, however, are placed on nonaccrual status, unless the loan is both
well-secured and in the process of collection or renewal. Cash payments received
while a loan is classified as nonaccrual are recorded as a reduction of
principal as long as doubt exists as to collection.
 
    The Company is sometimes required to revise a loan's interest rate or
repayment terms in a troubled debt restructuring. A loan is considered a
restructured loan if, as a result of the borrower's financial condition, the
Company has elected to modify it by accepting below market terms either by
granting an interest rate concession or deferring principal or interest payments
or both. In order for a restructured loan to be eligible to be reclassified as a
fully performing loan, the following must be satisfied: (i) the borrower must
generally have been current in meeting the restructured terms for at least six
consecutive month and (ii) the restructured loan must have an interest rate and
other features that are at least equivalent to market terms. Inevitably, not all
restructured loans will be viable as restructured, and it may be necessary for
the Company to make further concessions or to transfer the loan to nonaccrual
status or OREO. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations." The Company records OREO at fair value at the time
of acquisition, less estimated costs of sale.
 
COMPETITION
 
    There is intense competition in California and elsewhere in the United
States in attracting and retaining deposit accounts, and in making loans to
small businesses and other borrowers. The primary factors in the competition for
deposits are interest rates, personalized services, the quality and range of
 
                                       35
<PAGE>
financial services, convenience of office locations and office hours. The
Company competes for deposits primarily with other commercial banks, savings
institutions, credit unions, money market funds and other investment
alternatives. The primary factors in the competition for loans are interest
rates, loan origination fees, the quality and range of lending services and
personalized services. The Company competes for loans, primarily with other
commercial banks, savings institutions, mortgage banking firms, credit unions
and other financial intermediaries. In addition, our Automobile Lending Division
competes with the financial services affiliates of the major automobile
manufacturers. The Company faces competition for deposits and loans throughout
its market areas not only from local institutions but also from out-of-state
financial intermediaries that have opened loan production offices or that
solicit deposits in its market areas. Many of the financial intermediaries
operating in the Company's market areas offer certain services, such as trust
and investment services, that the Company does not offer directly. Additionally,
as a consequence of recent bank acquisitions and mergers in the Company's market
- -- including the mergers of BankAmerica Corporation and Wells Fargo & Company
with NationsBank Corporation and Norwest Corporation, respectively -- many of
the Company's competitors have greater financial and marketing resources and
name recognition than the Company and have statewide or nationwide operations
that may give them opportunities to realize greater efficiencies and economies
of scale than the Company. Moreover, recent developments in technology and mass
marketing have permitted larger institutions to market loans more aggressively
to small business borrowers.
 
    Federal legislation enacted in August 1998 eased membership limits on credit
unions, which previously were permitted to serve only members that shared a
single, common bond. Specifically, the legislation provides that
occupation-based credit unions may serve unrelated companies as long as such
companies have fewer than 3,000 employees. The Company expects that such
legislation will increase the ability of credit unions to compete with community
banks, such as the Banks, for both deposits and loans.
 
    The Company competes principally on the basis of personalized attention and
special services that it provides its customers, principally individuals and
small to medium-sized businesses. Its marketing activity focuses primarily on
promotional activities by and referrals from the Banks' officers, directors and
employees. Most of the Company's offices offer extended weekday banking hours
and some branches offer Saturday banking hours. The Company also operates
drive-up banking facilities at 12 of its branches and provides a variety of
personalized services. In addition, the Company operates 24-hour automatic
teller machines ("ATMs") at 24 of its locations and is a member of Instant
Teller network and Plus System network, which link bank ATMs nationwide.
 
EMPLOYEES
 
    The Company had approximately 662 full-time equivalent employees as of
December 31, 1998, of whom 69 were officers who held titles of Vice President or
above. The Company believes that its employee relations are satisfactory. See,
however, "Risk Factors -- We are dependent on the contributions of our key
management personnel." None of the Company's employees is represented by a union
or covered under a collective bargaining agreement.
 
PROPERTIES
 
    The Company's executive office is located in Laguna Hills, California, where
it leases a site that is physically contiguous to one of Eldorado Bank's
branches. Eldorado Bank is headquartered on a site owned by it in Tustin,
California, and Antelope Valley Bank is headquartered on a site owned by it in
Lancaster, California.
 
    In addition to the Banks' headquarters and the Laguna Hills location, the
Company owns 10 of its branch offices, one of which is subject to a ground
lease, and leases the remaining 12 offices. The Company also leases several
locations for various administrative offices associated with the Mortgage
Banking Division and the Equipment Leasing Division. The Company's aggregate
rental expense under such leases
 
                                       36
<PAGE>
was $2.6 million for the year ended December 31, 1998. For additional
information regarding the Company's lease obligations, see Note 17 to the
Supplemental Consolidated Financial Statements. At December 31, 1998, the net
book value of the property and leasehold improvements of the offices of the
Company amounted to $12.4 million. The Company's properties that are not leased
are owned free and clear of any mortgages. The Company believes that all of its
properties are appropriately maintained and are suitable for their respective
present needs and operations.
 
LEGAL PROCEEDINGS
 
    As of the date of this prospectus, no litigation is pending against the
Company itself. Eldorado Bank is the defendant in an action filed in 1994 by a
former officer of CSB's Stockton, California loan production office, alleging
wrongful termination, breach of contract, defamation and various other causes of
action. A central element of the employee's claim is that CSB terminated him in
retaliation for his reporting of alleged violations of consumer lending laws
committed by another employee of CSB's Stockton office. The Company's position
is that the former employee's claims are without merit and that CSB terminated
him because it reasonably believed he had acted insubordinately by retaliating
against a subordinate who had complained of the former employee's conduct. In
October 1997, a jury awarded the former employee $3.8 million in damages,
including $2.0 million in punitive damages. The trial court subsequently reduced
the award to $2.0 million, including $500,000 in punitive damages, and Eldorado
Bank recorded a purchase accounting adjustment for the CSB acquisition in an
amount equal to the reduced judgment. Both the Company and its former employee
have filed appeals, with the former employee seeking to have the total amount of
the jury's punitive damage award reinstated. Interest accrues on the judgment at
the statutory rate of 10%, and as of December 31, 1998, the judgment, including
interest, was equal to $2.6 million. There can be no assurance, however, that
the Company will not incur additional expense in connection with such matter or
that an adverse outcome in the appeal will not have a material adverse effect on
the Company's results of operations.
 
    The Company is from time to time subject to various legal actions (in
addition to those described above) that are considered to be part of its normal
course of business. Management, after consultation with legal counsel, does not
believe that the ultimate liability, if any, arising from those other actions
will have a material adverse effect on the financial position or results of
operations of the Company.

                      SUPPLEMENTAL SELECTED FINANCIAL DATA
 
    Supplemental selected financial data as of and for the five years ended
December 31, 1998 are derived from, and should be read in conjunction with, the
Company's Supplemental Consolidated Financial Statements appearing elsewhere in
this prospectus, which have been audited by the Company's independent
accountants. The acquisition of Antelope Valley Bank was treated for accounting
purposes as a pooling of interests, and therefore, the financial information
presented in the table below treats the acquisition as if it had been completed
at the beginning of the earliest period presented. The following supplemental
selected financial data should also be read in conjunction with the Supplemental
Consolidated Financial Statements of Eldorado and the Notes thereto, appearing
elsewhere in this prospectus, and the information set forth under
"Capitalization" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations." As described elsewhere in this prospectus,
because of the three acquisitions that the Company completed between September
1995 and June 30, 1997, which were accounted for using the purchase method of
accounting, the Company's historical operating results prior to June 30, 1997
are of limited relevance in evaluating the Company's historical financial
performance and predicting the Company's future operating results.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
                                  INTRODUCTION
 
    On January 22, 1999, the Company completed the acquisition of Antelope
Valley Bank. In connection with the acquisition, the Company issued to the
shareholders of Antelope Valley Bank approximately 2.8 million shares of common
stock. See "Recent Developments." The acquisition was treated for accounting
purposes as a pooling of interests. Accordingly, the financial information
contained in this section treats the acquisition of Antelope Valley Bank as if
it had been completed prior to the periods presented herein, and should be read
in conjunction with the Supplemental Consolidated Financial Statements of the
Company and the Notes thereto included in this prospectus.
 
    Prior to September 1995, the predecessor to the Company, SDN Bancorp, Inc.,
owned a single bank, San Dieguito National Bank ("San Dieguito"), with
approximately $56 million in assets, that was categorized as "critically
undercapitalized" by federal regulators. In September 1995, the Company was
recapitalized by DCG, a limited partnership controlled by Mr. Keller and a
majority of the other directors of the Company. Between September 1995 and June
30, 1998, the Company acquired three banks -- Liberty National Bank ("Liberty"),
Commerce Security Bank ("CSB") and Eldorado Bank -- increasing the Company's
tangible assets by $779 million. The Company completed its largest acquisition
- -- Eldorado Bancorp and its subsidiary bank, Eldorado Bank -- in June 1997,
which increased the Company's assets by approximately $404 million. The Liberty
acquisition was completed as of March 31, 1996, and the CSB acquisition was
completed as of September 1, 1996. See "Business -- Prior Acquisitions." Each of
those acquisitions was accounted for using the purchase method of accounting for
business combinations, and therefore the operating results of those banks are
reflected in the Company's financial statements only from the date of
acquisition. Consequently, the period-to-period comparisons in this section are
significantly affected by the timing of those acquisitions. For historical
financial information concerning the Company, see the Company's Supplemental
Consolidated Financial Statements and Consolidated Financial Statements and the
Notes related thereto.
 
    Within the recent past, CSB, Liberty and San Dieguito were adversely
affected by a variety of factors, including high levels of nonperforming assets,
reliance on high-cost brokered deposits and excessive overhead costs. The high
levels of nonperforming assets and related overhead costs were partly
attributable to adverse economic conditions, including declining real estate
values, that California experienced during the early to mid-1990s. See "Business
- -- Prior Acquisitions."
 
    Effective June 30, 1997, the Company merged San Dieguito, Liberty, CSB and
Eldorado Bank into a single bank, which is known as Eldorado Bank. The Company
owns 100% of Eldorado Bank, which now is one of the Company's two banking
subsidiaries, the other being Antelope Valley Bank.
 
    Contained within this prospectus are various measures of financial
performance that have been calculated excluding the amortization of intangibles.
These measures are identified as "excluding goodwill amortization" and have been
provided to assist the reader in evaluating the core performance of the Company.
This presentation is not defined by Generally Accepted Accounting Principles
("GAAP"), but management believes it to be beneficial to gaining an
understanding of the Company's financial performance in comparison to its peer
group.
 
    Except for the historical information contained herein, the following
discussion contains forward-looking statements that involve risks and
uncertainties. The Company's actual results could differ materially from those
discussed here. Factors that could cause or contribute to such differences
include, but are not specifically limited to, changes in regulatory climate,
shifts in the interest rate environment, changes in economic conditions of
various markets the Company serves, as well as the other risks detailed in this
section and in "Risk Factors" above.

              FOR THE YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996
 
    The Company had net income of $5.4 million for the year ended December 31,
1998, an increase of $504,000 or 10.3%, compared to net income of $4.9 million
for the year ended December 31, 1997. The increase in net income is due to an
increase in net interest income and noninterest income of $11.6 million and $6.8
million, respectively, partially offset by increased provision for loan and
lease losses, noninterest expense and income taxes of $3.0 million, $12.9
million and $2.0 million, respectively. Basic net income per share in 1998 was
$0.35 compared to $0.41 in 1997, while diluted net income per share in 1998 was
$0.33 per share compared to $0.37 in 1997. Excluding the amortization of
goodwill and other intangibles, basic and diluted earnings per share for the
year ended December 31, 1998 were $0.68 and $0.65, respectively, as compared to
$0.69 and $0.62 for the year ended December 31, 1997. The Company's return on
average assets was .45% and its return on average common equity was 3.90% for
the year ended December 31, 1998, as compared to .55% and 4.98%, respectively,
for the year ended December 31, 1997. Excluding the amortization of goodwill and
other intangibles, return on average assets was .78% and return on average
common equity was 7.66% for the year ended December 31, 1998, as compared to
 .88% and 8.42%, respectively, for the year ended December 31, 1997.
 
    The Company had net income of $4.9 million for the year ended December 31,
1997, an increase of $491,000, or 10.0%, compared to net income of $4.4 million
for the year ended December 31, 1996. The increase in net income is due to an
increase in net interest income, noninterest income and tax benefit of $23.0
million and $9.7 million, respectively, partially offset by increased provision
for loan and lease losses, noninterest expense and income taxes of $1.3 million,
$26.5 million and $4.4 million, respectively. Basic net income per share in 1997
was $0.41 per share compared to $0.81 in 1996, while diluted net income per
share in 1997 was $0.37 compared to $0.81 in 1996. Excluding the amortization of
goodwill and other intangibles, basic and diluted earnings per share for the
year ended December 31, 1997 were $0.69 and $0.62, respectively, as compared to

average assets was .55% and its return on average common equity was 4.98% for
the year ended December 31, 1997. For the year ended December 31, 1996, the
Company's return on average assets was 1.16% and its return on average common
equity was 12.47%. Excluding the amortization of goodwill and other intangibles,
return on average assets was .88% and return on average common equity was 8.42%
for the year ended December 31, 1997, as compared to 1.23% and 12.47%,

RESULTS OF OPERATIONS
 
NET INTEREST INCOME AND NET INTEREST MARGIN
 
    Net interest income, the difference between the interest generated from
interest-earning assets and the interest paid for interest-bearing liabilities,
continues to be the Company's primary source of revenue. The Company's net
interest income increased $11.6 million in 1998 due to an increase of $22.2
million in interest income partially offset by increased interest expense of
$10.6 million. Increased interest income was primarily the result of the higher
volume of earning assets that was partially offset by decreased yields on
earning assets. The average yield on interest-earning assets declined to 8.9% in
1998 from 9.2% in 1997. The decrease was due to a reduction in yields on
marketable securities, a decline in the prime lending rate in the fourth quarter
of 1998 and increased price competition for loans throughout the year. Interest
expense increased as a result of the increased volume of interest-bearing
liabilities and an increase in the average cost of interest-bearing liabilities
to 4.4% in 1998 from 4.3% in 1997. The increase in the cost of average
interest-bearing liabilities primarily reflects greater price competition for
deposits, particularly for high balance accounts such as Title and Escrow
Deposits. See "Business--Products and Services-- Community Banking Division." As
a result of those factors, the net yield on earning assets declined to 5.4% in
1998 from 5.9% in 1997.
 
    The Company's net interest income increased $23.0 million in 1997 due to an
increase of $36.7 million in interest income partially offset by increased
interest expense of $13.7 million. Interest income and interest expense
increased primarily due to an increase in interest earning assets and
liabilities acquired in
 
                                       41
<PAGE>
the acquisition of Eldorado Bancorp. Increased interest income was partially
offset by decreased yields on earning assets. The average yield on
interest-earning assets declined to 9.2% in 1997 from 9.4% in 1996. Interest
expense increased because of the increase in interest bearing liabilities and an
increase in the average cost of interest-bearing liabilities from 4.3% in 1997
to 4.1% in 1996. As a result of those factors, the net yield on earning assets
declined to 5.9% in 1997 from 6.1% in 1996
 
    Loan fee income increased $1.4 million to $4.5 million in 1998 from $3.1
million in 1997. Loan fee income increased $1.6 to $3.1 million in 1997 from
$1.5 in 1996. Those increases are primarily attributable to the fees earned on
the sale of SBA loans into the secondary market. See "Business--Products and
Services--Community Banking Division."
 
    The following table presents, for the periods indicated, the distribution of
average assets, liabilities and shareholders' equity, as well as the total
dollar amounts of interest income from average interest-bearing assets and the
resultant yields, and the dollar amounts of interest expense and resultant cost
expressed in both dollars and rates. Nonaccrual loans are included in the
calculation of the average loans while nonaccrued interest thereon is excluded
from the computation of rates earned.

PROVISION FOR LOAN AND LEASE LOSSES
 
    During 1998, the Company charged a total of $5.6 million against operations
to increase its allowance for loan and lease losses, as compared to $2.5 million
in 1997. The increase in the provision for loan and lease losses primarily
resulted from an increase in net charge-offs attributable to the inclusion of a
full year of operations of the former Eldorado Bancorp as compared to a partial
year in 1997. The increase in the provision in 1998 is also attributable to a
94.9% increase in the ratio of net charge-offs to average portfolio loans and
leases to 0.76% for 1998 from 0.39% for 1997. That increase primarily resulted
from the charge-off of two loans having an aggregate principal balance of $2.1
million. Those loans, which were acquired in the CSB and Eldorado Bancorp
acquisitions, were performing in accordance with their terms as of December 31,
1997; however, in early 1998 the Company became aware of a deterioration in the
borrowers' financial condition that, as dictated by the Company's internal
guidelines, necessitated the charge-offs. The increase in the ratio of net
charge-offs to average portfolio loans and leases also reflects an increase in
equipment leases as percentage of total portfolio loans and leases. At December
31, 1998, leases constituted 13.6% of total portfolio loans and leases as
compared to 6.3% at December 31, 1997. See "--Financial Condition--Allowance for
Loan and Lease Losses."
 
    The provision for loan and lease losses for 1997 was $2.5 million compared
to $1.2 million during 1996. The increase is primarily attributable to the
increase in net charge-offs as a result of the acquisition of Eldorado Bancorp
in June 1997. The increase in net charge-offs more than offset a decline in the
ratio of net charge-offs to average portfolio loans and leases to 0.39% for 1997
from 0.48% for 1996.
 
NONINTEREST INCOME
 
    Noninterest income increased by $6.8 million, or 35.3%, to $25.9 million in
1998 from $19.1 million in 1997. The increase was primarily due to income
derived from the Mortgage Banking Division and, to a

<PAGE>
lesser extent, the result of the inclusion of a full year of operations for
Eldorado Bancorp in 1998 as compared to the inclusion of only a partial year in
1997. The gain on sale of mortgage loans increased by $5.1 million, or 74.2%, to
$12.0 million in 1998 from $6.9 million in 1997 as a result of the increase in
mortgage loan originations and sales. See "Business."
 
    Noninterest income increased by $9.7 million, or 50.8%, to $19.1 million in
1997 from $9.4 million in 1996. The increase was primarily due to income derived
from the Mortgage Banking Division, to a lesser extent, to the inclusion of a
partial year of operations for Eldorado Bancorp. The gain on sale of mortgage
loans increased by $5.2 million, or 298.8%, to $6.9 million in 1997 from $1.7
million in 1996 as a result of the increase in mortgage loan originations and
sales.

NONINTEREST EXPENSES
 
    Noninterest expense increased by $12.9 million, or 25.6%, to $63.3 million
in 1998 from $50.4 million in 1997. The increase in expense is largely
attributable to variable expenses incurred related to increased loan origination
volumes in the Mortgage Banking Division and also in part to the expenses
associated with the acquired operations of Eldorado Bancorp for the full year in
1998 compared to only the partial year in 1997. Also included in this increase
is the amortization of goodwill, which for 1998 was $4.0 million compared to
$2.9 million in 1997.
 
    Noninterest expense increased by $26.5 million to $50.4 million in 1997 from
$23.9 million in 1996. The increase in expense is largely attributable to the
expenses associated with the acquired operations of Eldorado Bancorp, which was
acquired in June 1997. Expenses increased in the categories of salaries and
employee benefits by $10.0 million, occupancy and equipment by $3.2 million and
other noninterest expenses by $13.3 million. Included in this increase is a
provision for recourse obligations of $2.0 million only in 1997 and the
amortization of goodwill, which increased by $2.6 million, or 90.7%, to $2.9
million in 1997 from $268,000 in 1996. The increase in noninterest expense in
1998 was partially offset by a decrease in the provision for mortgage recourse
obligations, for which none was made in 1998 or 1996. The recourse obligations
were incurred in connection with CSB's bulk sales of loan servicing rights for
VA Loans, which sales were effected prior to the Company's acquisition of CSB.
 
    The efficiency ratio, which measures the percentage of net revenue that is
paid as noninterest expenses, increased to 73.6% for 1998 from 73.0% in 1997
which was an improvement from 80.0% for 1996. The decrease in the efficiency
ratio since 1996, which indicates increased operating efficiency as a smaller
portion of net revenue is used for the cost of operations, primarily resulted
from cost savings gained in integrating the banks we acquired in 1996 and 1997.
For purposes of this prospectus, the Company's efficiency ratio is defined as
noninterest expense--excluding the amortization of goodwill and other
intangibles, losses and carrying costs of OREO and nonrecurring provisions for
recourse obligations--as a percentage of total revenue less interest expense.
The Company's definition of efficiency ratio may not be comparable to that used
by other banking companies.

</TABLE>
 
    The Company expects that during the quarter ending March 31, 1999 it will
recognize approximately $800,000 of expenses, net of taxes, related to the
Antelope acquisition, including investment banking and professional fees and
severance costs.
 
PROVISION FOR INCOME TAXES
 
    The Company's tax provision increased by $2.0 million, or 49.2%, to $6.0
million in 1998 from $4.0 million in 1997. This increase in taxes resulted from
higher pre-tax earnings in 1998 of $11.4 million compared to $8.9 million in
1997. The Company's effective tax rate for 1998 (52.6%) is higher than the
applicable statutory rate (42.0%) because goodwill amortization is a charge to
earnings for financial statement purposes and is not deductible for federal
income tax purposes.
 
    The Company recorded a tax provision on continuing operations totaling $4.0
million in 1997 compared to a net benefit of $373,000 in 1996. The benefit in
1996 resulted from the release of the valuation allowance which had previously
been provided against the Company's federal and state deferred tax assets. That
valuation allowance had been provided against the Company's net operating loss
carry forwards and other tax attributes. However, the Company's operating
results adequately supported the realizability of the deferred tax assets at
December 31, 1997 and 1996 and therefore the valuation allowance was no longer
required. Of the $2.0 million total allowance which was released in 1996,
approximately $413,000 was utilized to offset tax expense related to 1996
operating income.
 
FINANCIAL CONDITION
 
    Total assets of the Company at December 31, 1998 were $1.4 billion, an
increase of $305.5 million, or 28.0%, compared to total assets of $1.1 billion
at December 31, 1997. The increase in total assets since December 31, 1997 is
primarily due to an increase in earning assets and cash that was funded by an
increase in the Company's deposit liabilities. Total earning assets of the
Company at December 31, 1998 increased $280.2 million, or 31.3%, to $1.2 billion
compared to total earning assets of $894.3 million at December 31, 1997. The
increase in total earnings assets since December 31, 1997 is primarily due to an
increase in mortgage loans held for sale and investment securities. Cash at
December 31, 1998 was $122.5 million, an increase of $23.1 million, or 23.3%,
from $99.4 million at December 31, 1997. The increase in cash is due primarily
to the increased liquidity demands attributable to the increase in deposit
liabilities that increased $288.4 million, or 30.9%, to $1.2 billion at December
31, 1998 from $933.1 million at December 31, 1997.

<PAGE>
LOANS AND LEASES
 
    Total loans and leases of the Company at December 31, 1998 were $881.7
million, an increase of $159.7 million, or 22.1%, from $722.0 million at
December 31, 1997. The increase in mortgage loans held for sale is primarily
responsible for the increase in total loans and leases. Included in total loans
and leases at December 31, 1998 are $248.8 million of mortgage loans held for
sale that increased $152.6 million, or 158.9%, from $96.2 million at December
31, 1997.
 
    Portfolio loans and leases increased by $6.3 million, or 1.0%, to $654.1
million at December 31, 1998, from $647.8 million at December 31, 1997. The
increase in portfolio loans and leases is primarily attributable to an increase
of $48.1 million, or 117.7%, in equipment leases as well as an increase of $14.5
million, or 10.6%, in installment loans to individuals that resulted primarily
from growth in Antelope Valley Bank's automobile lending. The increases in those
lending categories were nearly offset, however, by declines in the volume of
most categories of commercial loans. The Company experienced the greatest
reduction in commercial real estate loans, which decreased by $36.3 million, or
15.4%, to $198.9 million at December 31, 1998, from $235.2 million at December
31, 1997. The decrease in commercial loans is primarily attributable to
competitive pricing pressures, as many borrowers elected to refinance their
loans at lower rates offered by competing lenders.
 
    The following table sets forth the amount of loans and leases outstanding
for the Company at the end of each of the years indicated, according to type of
loan, inclusive of mortgage loans held for sale. The Company has no foreign
loans or energy-related loans as of the dates indicated.

    The Company's impaired loans pursuant to Statement of Financial Accounting
Standards ("SFAS") 118 are loans that are nonaccrual and those that have been
restructured. Loans aggregating $9.8 million at December 31, 1998 were
designated as impaired in accordance with SFAS 114 as amended by SFAS 118. The
Company's impaired loans are all collateral dependent, and as such the method
used to measure the amount of impairment on these loans is to compare the loan
amount to the fair value of collateral. In calculating the allowance for loan
and lease losses that was required under the Company's internal guidelines,
management determined that a minimun of $1.3 million should be included in the
allowance at December 31, 1998 because of the risk to the loan and lease
portfolio represented by impaired loans. At December 31, 1997, loans aggregating
$14.6 million were designated as impaired and management determined that a
minimum of $1.7 million should be included in the allowance because of the risk
to the loan and lease portfolio represented by such impaired loans. For 1998,
additional gross interest income of $1.1 million would have been recorded on
impaired loans, and for 1997 additional gross interest income of $2.1 million
would have been recorded on impaired loans, in each case had the loans been
current. No accrued but unpaid interest income on such loans was in fact
included in the Company's net income during 1998 or 1997.
 
    At December 31, 1998, the Company had OREO properties with an aggregate
carrying value of $1.6 million. During 1998, properties with a total carrying
value of $881,000 were added to OREO, properties with a total carrying value of
$1.7 million were sold and OREO properties were written down by approximately
$353,000. At December 31, 1997, the Company had OREO properties with an
aggregate carrying value of $2.7 million. During 1997, properties with a total
carrying value of $4.2 million were added to OREO, of which $481,000 was
acquired in the acquisition of Eldorado Bancorp and $3.7 million was acquired as
a result of foreclosures. OREO properties with a total carrying value of $5.7
million were sold and properties were written down by approximately $1.1 million
during 1997.

ALLOWANCE FOR LOAN AND LEASE LOSSES
 
    The allowance for loan and lease losses was $9.2 million, or 1.4% of gross
portfolio loans and leases at December 31, 1998, compared to $10.9 million or
1.7% of gross portfolio loans and leases, at December 31, 1997, and $6.5
million, or 1.8% of gross portfolio loans and leases, at December 31, 1996.
 
    The decrease in the allowance for loan and lease losses at December 31, 1998
as compared to December 31, 1997 reflects a reduction in nonperforming loans and
leases. Nonperforming loans and leases totaled $10.9 million, or 1.7% of total
portfolio loans and leases, at December 31, 1998, as compared to $19.4 million,
or 3.0% of total portfolio loans and leases, at December 31, 1997. The decrease
in nonperforming loans and leases in 1998 was primarily the result of the volume
of net loans and leases charged to the allowance for loan and lease losses in
1998. Charged off loans and leases, net of recoveries, totaled $7.3 million for
1998, representing an increase of $5.1 million, or 228.3%, from $2.2 million for
1997. The increase in net charge-offs primarily resulted from the charge-off of
two loans acquired in prior acquisitions and the increase in equipment leases as
a percentage of total portfolio loans and leases, as described elsewhere in this
prospectus. See "--Results of Operations--Provision for Loan and Lease Losses."
The increase in the allowance for loan and lease losses at December 31, 1997 as
compared to December 31, 1996 reflects the acquisition of the $4.1 allowance of
Eldorado Bancorp in June 1997.

</TABLE>
 
    In allocating the Company's allowance for loan and lease losses, management
has considered the credit risk in the various loan categories in its portfolio.
As such, the allocations of the allowance for loan and lease losses are based
upon the average aggregate historical net loan losses experienced by each of its
current or acquired subsidiary banks. While the Company has made a reasonable
effort to allocate the allowance to specific categories of loans, management
believes that any allocation of the allowance for loan and lease losses into
loan categories lends an appearance of exactness which does not exist, in that
the allowance for loan and lease losses is utilized as a single unallocated
allowance available for losses on all types of loans and leases, and actual
losses in loan categories may vary from the amounts allocated to such
categories.

DEPOSITS
 
    Total deposits were $1.2 billion at December 31, 1998, an increase of $288.4
million, or 30.9%, compared to $933.1 million at December 31, 1997. The increase
in total deposits since December 31, 1997 is primarily attributable to an
increase in savings deposits of $199.0 million, or 168.2%. Noninterest-bearing
demand accounts were $313.9 million, or 25.7% of total deposits, at December 31,
1998. Interest-bearing deposits are comprised of interest-bearing demand
accounts, regular savings accounts, money market accounts, time deposits of
under $100,000 and time deposits of $100,000 or more which were $154.9 million,
$317.3 million, $119.8 million, $198.4 million and $117.2 million, respectively,
or 12.7%, 26.0%, 9.8%, 16.3% and 9.6% of total deposits, respectively, at
December 31, 1998. The increase in savings deposits at December 31, 1998
compared to December 31, 1997 is primarily attributable to an increase in Title
and Escrow Deposits. See "Business--Products and Services--Community Banking
Division."

an increase of $3.7 million, or 12.1%, from $30.2 million at December 31, 1997.
The increase in borrowings was primarily due to an increase in Federal funds
purchased that was $5.9 million at December 31, 1998, an increase of $3.9
million, or 187.8%, compared to $2.1 million at December 31, 1997.
 
                               CAPITAL RESOURCES
 
    Current regulatory capital standards generally require banks and holding
companies to maintain a ratio of "core" or "Tier 1" capital (consisting
principally of common equity) to adjusted total assets ("Tier 1 Leverage Ratio")
of at least 3%, a ratio of Tier 1 capital to risk-weighted assets of at least 4%
("Tier 1 Risk-Weighted Ratio"), and a ratio of total capital (which includes
Tier 1 capital plus certain forms of subordinated debt, a portion of the
allowance for loan and lease losses and preferred stock) to risk-weighted assets
("Total Risk-Weighted Ratio") of at least 8%. Risk-weighted assets are
calculated by multiplying the balance in each category of assets according to a
risk factor which ranges from zero for cash assets and certain government
obligations to 100% for some types of loans and adding the products together.
See "Supervision and Regulation--Capital Adequacy Requirements."
 
    The Company and Eldorado Bank were adequately capitalized and Antelope
Valley Bank was well capitalized at December 31, 1998 for federal regulatory
purposes. As of December 31, 1998, the Company and its subsidiary banks had a
Tier 1 Leverage Ratio, Tier 1 Risk-Weighted Ratio, and Total Risk-Weighted Ratio
as follows:

                                   LIQUIDITY
 
    The Company relies on deposits as its principal source of funds and,
therefore, must be in a position to service depositors' needs as they arise.
Management attempts to maintain a loan-to-deposit ratio of not greater than 80%
and a liquidity ratio (liquid assets--including cash and due from banks, Federal
funds sold and investment securities--to total deposits) of approximately 20%.
The average loan-to-deposit ratio was 78.3% in 1998, 75.6% in 1997 and 70.3% in
1996. The average liquidity ratio was 27.9% in 1998, 30.4% in 1997 and 31.7% in
1996. At December 31, 1998, the Company's loan-to-deposit ratio was 73.9% and
the liquidity ratio was 32.3%. While fluctuations in the balances of a few large
depositors cause temporary increases and decreases in liquidity from time to
time, the Company has not experienced difficulty in dealing with such
fluctuations from existing liquidity sources.
 
    Should the level of liquid assets (primary liquidity) not meet the liquidity
needs of the Company, the Company could employ other available sources of liquid
assets (secondary liquidity), including the
 
                                       53
<PAGE>
purchase of Federal funds, sale of securities under agreements to repurchase,
sale of loans, window borrowing from the Federal Reserve Bank and, to a lesser
extent, borrowings from the Federal Home Loan Bank of San Francisco ("FHLB"),
could be employed. The Company has relied primarily upon the purchase of Federal
funds and the sale of securities under agreements to repurchase for secondary
sources of liquidity. At December 31, 1998 the Company had approximately $17
million of unused borrowing capacity for FHLB advances. In order to borrow from
the Federal Reserve, the Company would be required to physically deliver to the
Federal Reserve collateral consisting of marketable Government securities. At
December 31, 1998, the Company has no such collateral at the Federal Reserve. At
December 31, 1998, the Company had unpledged collateral that it could deliver to
the Federal Reserve sufficient to support up to $107 million of window
borrowings.
 
                             YEAR 2000 PREPAREDNESS
 
    The Year 2000 issue is a computer programming concern that may affect many
electronic processing systems. Until relatively recently, in order to minimize
the length of data fields, most computer programs eliminated the first two
digits of the year. This problem could affect computers leaving them unable to
distinguish dates in the twentieth and twenty-first centuries. For example,
date-sensitive calculations that treat "00" as the year 1900, rather than 2000.
Secondly, years that end in "00" are not leap years, except for an anomaly in
the year 2000. This anomaly could result in miscalculations when processing
critical date-sensitive information relating to periods after December 31, 1999.
 
    The Year 2000 issue may adversely affect the Company's information
technology systems, such as its item and data processing applications. The Year
2000 issue also may affect so-called embedded technology, such as
microprocessors that control some of the Company's security systems and
telecommunication equipment.
 
    The Company has determined that certain of its computer software
applications will need to be modified or replaced in order to maintain their
functionality as the year 2000 approaches. In response, a plan has been
developed that provides for the assessment of its material internal systems,
programs and data processing applications as well as those provided to the Banks
by third-party vendors. The Company expects that system conversions and testing
will be completed in all material respects prior to June 30, 1999. Based upon
the Company's evaluation of its Year 2000 preparedness, management does not
expect that the Year 2000 issue as it relates to information systems and
embedded technology that are within the Company's direct control will have a
material adverse effect on the Company's business, financial condition or
results of operations. However, Year 2000 problems may turn out to exist in
portions of computer programs not now suspected, and there can be no assurance
that the Company will not be adversely affected by this problem.
 
    Ultimately, the potential impact of the Year 2000 issue will depend not only
on the corrective measures the Company undertakes, but also on the way in which
the Year 2000 issue is addressed by governmental agencies, businesses and other
entities who provide data to, or receive data from the Banks or whose financial
condition or operational capability is important to the Company such as
significant suppliers or customers. The Company has initiated communications
with significant customers and vendors to evaluate the status of efforts by
those third parties to remediate their own Year 2000 issues; however, it is not
possible, at present, to determine the financial effect on the Company if a
significant customer's and/or vendor's remediation efforts are not completed in
a timely manner. The vendors to which the Community Banking Divisions of
Eldorado Bank and Antelope Valley Bank have outsourced their data and item
processing have received "satisfactory" ratings in 1998 from the Federal
Financial Institutions Examination Council ("FFIEC") (the umbrella organization
of federal bank regulators) with respect to the status of those vendors'
preparedness for the Year 2000 issue.
 
    In addition, because the Company's day-to-day operations are heavily
dependent on its ability to communicate information throughout its network of
branches and loan production offices, the Company
 
                                       54
<PAGE>
would be particularly susceptible to any possible effects that the Year 2000
issue has on local and national communications systems, including without
limitation, telephone and data lines, because of the difficulty in implementing
viable contingency plans. Any interruption or malfunction of such systems could
have a material adverse effect on the Company.
 
    Furthermore, bank regulatory agencies, as part of their supervisory
function, have recently issued guidance under which they are assessing and will
assess Year 2000 readiness. The failure of a financial institution, such as the
Company, to take appropriate steps to address deficiencies in its Year 2000
project management process may result in one or more regulatory enforcement
actions which could have a material adverse effect on such institution. Such
actions may include the imposition of civil money penalties, or result in the
delay or denial of regulatory applications. In the latest joint examination of
the Banks by the Federal Reserve and the DFI, the Banks received "satisfactory"
ratings with respect to their Year 2000 plans and levels of preparedness.
 
    The Company's noninterest expense for 1998 included $397,000 in direct costs
associated with the Year 2000 issue. The Company estimates its total costs
accrued during the year ending December 31, 1999 will be less than $500,000, and
none of those costs are expected to materially affect the Company's results of
operations in any one reporting period. In light of the complexity of the Year
2000 problem and its potential effect on both the Company and third parties that
interact with the Company, however, there can be no assurance that the Company's
costs associated with the Year 2000 issue will be as estimated. The Company does
not intend to obtain insurance against any Year 2000 risks.
 
                            ECONOMIC CONSIDERATIONS
 
CALIFORNIA ECONOMY
 
    The financial condition of the Company has been, and is expected to continue
to be, affected primarily by overall general economic conditions and the real
estate market in California. The commercial banking and automotive lending
activity of the Company concentrates on serving the needs of small and
medium-size businesses, professionals and individuals located primarily in
Southern California. The residential mortgage origination activity is centered
in California and four other surrounding states, and originations of small
equipment leases are done throughout the country with a concentration in
California.
 
    Although the general economy in Southern California has recovered
substantially from the prolonged recession that had adversely affected the
ability of certain borrowers to satisfy their obligations to the Company, the
Company's financial condition and operating results are subject to changes in
economic conditions in that region. Moreover, there can be no assurance that
conditions will not deteriorate in the future and that such deterioration will
not have a material adverse effect on the Company's financial condition or
results of operations.
 
    In 1998, California's Gross State Product ("GSP") approached $1.1 trillion
and is expected to exceed $1.1 trillion in 1999. For the nine months ended
September 30, 1998, exports to foreign countries totaled $80.0 billion or
approximately 10% of the State's GSP, reflecting a 6.1% decline from $85.2
million for the comparable period in 1997. California, with its greater
dependence on Asian trade and investment, is more at risk from Asia's economic
problems than the rest of the United States. For the first three quarters of
1998, exports to Asian countries totaled $41.3 billion and represented 51.6% of
California's total exports reflecting a decrease of 18.7% from $50.8 billion for
the same period in 1997. Despite this significant drop in export to Asian
countries, California's total exports only decreased by 6.1% for the first three
quarters of 1998 compared to 1997 primarily as a result of an increase in
growing exports to Mexico, Canada, Australia and Western Europe. There can be no
assurance that the State's economy will not be adversely affected by prolonged
weakness in one or more of the Asian economies. Weaker Asian demand for products
and services could potentially result in job losses, primarily in the high-tech
manufacturing, engineering, travel and entertainment industries. The Los Angeles
area is among the most vulnerable regions in California with its relatively
heavy concentration of high-tech, engineering and entertainment
 
                                       55
<PAGE>
firms. There can be no assurance that a deterioration of economic conditions in
California as a result of Asia's economic problems will not have a material
adverse effect on the Company's business, financial condition or result of
operations.
 
    In addition, a substantial portion of the Company's assets consist of loans
secured by real estate in Southern California with a lesser concentration in
Northern California. Historically, these areas have experienced on occasion
significant natural disasters, including earthquakes, brush fires and, recently,
certain significant weather abnormalities, including flooding and coastal
erosion, attributable to the weather phenomena known as "El Nino" and "La Nina."
The availability of insurance for losses from such catastrophes is limited. The
occurrence of one or more of those circumstances could impair the value of the
collateral for the Company's real estate secured loans and have a material
adverse effect on the Company.
 
INFLATION
 
    The majority of the Company's assets and liabilities are monetary items held
by the Company, the dollar value of which is not affected by inflation. Only a
small portion of total assets is in premises and equipment. The lower inflation
rate of recent years did not have the positive impact on the Company that was
felt in many other industries. The small fixed asset investment of the Company
minimizes any material misstatement of asset values and depreciation expenses
which may result from fluctuating market values due to inflation. A higher
inflation rate, however, may increase operating expenses or have other adverse
effects on borrowers of the Company, making collection more difficult for the
Company. Rates of interest paid or charged generally rise if the marketplace
believes inflation rates will increase. See "Risk Factors-- Changes in interest
rates may adversely affect our business."
 
                      RECENTLY ISSUED ACCOUNTING STANDARDS
 
    In June 1997 the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") 130, "Reporting
Comprehensive Income." This Statement requires all enterprises to report
comprehensive income as a measure of overall performance. Comprehensive income
is the change to equity (net assets) of a business during a period. For the
Company, this new standard is effective for 1998 and did not have a material
impact on the Company's financial statements.
 
    In June 1997, the FASB issued SFAS 131, "Disclosures About Segments of an
Enterprise and Related Information." This statement will change the way public
companies report information about segments of their business in their annual
financial statements and require them to report selected segment information in
their quarterly reports issued to shareholders. Companies will be required to
disclose segment data based upon how management makes decisions about allocating
resources to segments and measuring performance. For the Company, this new
standard is effective for 1998 and did not have a material impact on the
Company's financial statements.
 
    In February 1998, the FASB issued SFAS 132, "Employer's Disclosures about
Pensions and other Post-Retirement Benefits." This Statement standardizes the
disclosure requirements for pensions and other post-retirement benefits to the
extent practicable. For the Company, this new standard is effective for 1998 and
did not have a material impact on the Company's financial statements.
 
    In June 1998, the FASB issued SFAS 133, "Accounting for Derivative
Instruments and Hedging Activities." This Statement establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts (collectively referred to as
derivatives), and for hedging activities. It requires that an entity recognize
all derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. For the Company, this new
standard is effective in 2000 and is not to be applied retroactively to
financial statements of prior periods. The impact of this Statement, if any, is
yet to be determined.
 
                                       56
<PAGE>
    In October 1998, the FASB issued SFAS 134, "Accounting for Mortgage-Backed
Securities Retained after the Securitization of Mortgage Loans Held for Sale by
a Mortgage Banking Enterprise." This Statement establishes accounting and
reporting standards for securitization of mortgage loans. For the Company, this
new standard is effective in 1999, and the impact of this Statement, if any, is
yet to be determined.
 
           QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
    Market risk is the risk of loss in a financial instrument arising from
adverse changes in market prices and rates, foreign currency exchange rates,
commodity prices and equity prices. The Company's market risk arises primarily
from interest rate risk inherent in its lending and deposit taking activities.
To that end, management actively monitors and manages its interest rate risk
exposure. The Company does not have any market risk sensitive instruments
entered into for trading purposes. The Company seeks to manage its interest rate
sensitivity by matching the repricing opportunities on its earning assets to
those on its funding liabilities. Management uses various asset/liability
strategies to manage the repricing characteristics of its assets and liabilities
to ensure that exposure to interest rate fluctuations is limited within Company
guidelines of acceptable levels of risk-taking. Hedging strategies, including
the terms and pricing of loans and deposits, and managing the deployment of its
securities are used to reduce mismatches in interest rate repricing
opportunities of portfolio assets and their funding sources. It should be noted,
however, that because hedging instruments may not respond to changes in interest
rates to the same degree as the assets or liabilities being hedged, some
interest rate risks remain even in a fully hedged portfolio. For example, during
the quarter ended December 31, 1998, Eldorado incurred a loss of $1.1 million on
hedging activities primarily because of an unexpected change in the correlation
between the value of the mortgage loans in its pipeline and mortgage-backed
securities used for hedging. See "Risk Factors -- Changes in interest rates may
adversely affect our business."
 
    When appropriate, management may utilize off balance sheet instruments such
as interest rate floors, caps and swaps to hedge its interest rate position. A
Board of Directors approved hedging policy statement governs use of these
instruments. As of December 31, 1998, the Company had not utilized any interest
rate swaps or other such financial derivatives to alter its interest rate risk
profile.
 
    One way to measure the impact that future changes in interest rates will
have on net interest income is through a cumulative gap measure. The gap
represents the net position of assets and liabilities subject to repricing in
specified time periods. Generally, a liability sensitive gap position indicates
that there would be a net positive impact on the net interest margin of the
Company for the period measured in a declining interest rate environment since
the Company's liabilities would reprice to lower market rates before its assets
would. A net negative impact would result from an increasing interest rate
environment. Conversely, an asset sensitive gap indicates that there would be a
net positive impact on the net interest margin in a rising interest rate
environment since the Company's assets would reprice to higher market interest
rates before its liabilities would.
 
    The table below sets forth the distribution of repricing opportunities of
the Company's interest-earning assets and interest-bearing liabilities, the
interest rate sensitivity gap (i.e., interest rate sensitive assets less
interest rate sensitive liabilities), cumulative interest-earning assets and
interest-bearing liabilities, the cumulative interest rate sensitivity gap, the
ratio of cumulative interest-earning assets to cumulative interest-bearing
liabilities and the cumulative gap as a percentage of total assets and total
interest-earning assets as of December 31, 1998. The table also sets forth the
time periods during which interest-earning assets and interest-bearing
liabilities will mature or may reprice in accordance with their contractual
terms. The interest rate relationships between the repriceable assets and
repriceable liabilities are not necessarily constant and may be affected by many
factors, including the behavior of customers in response to changes in interest
rates. This table should, therefore, be used only as a guide as to the possible
effect changes in interest rates might have on the net margins of the Company.

    At December 31, 1998, the Company had $705.5 million in assets and $898.8
million in liabilities repricing within one year. This means that $193.3 million
more in interest rate sensitive liabilities than interest rate sensitive assets
will change to the then current rate (changes occur due to the instruments being
at a variable rate or because the maturity of the instrument requires its
replacement at the then current rate). The ratio of interest earning assets to
interest bearing liabilities maturing or repricing within one year at December
31, 1998 is .78 and management tries to maintain this ratio as close to 1.00 as
possible while remaining in a range between .80 and 1.20. Interest expense is
likely to be affected to a greater extent than interest income for any changes
in interest rates within one year from December 31, 1998. If rates were to fall
during this period, interest expense would decline by a greater amount than
interest income and net income would increase. Conversely, if rates were to
rise, the reverse would apply.
 
    Since interest rate changes do not affect all categories of assets and
liabilities equally or simultaneously, a cumulative gap analysis alone cannot be
used to evaluate the Company's interest rate sensitivity
 
                                       58

position. To supplement traditional gap analysis, the Company performs
simulation modeling to estimate the potential effects of changing interest
rates. The process allows the Company to explore the complex relationships
within the gap over time and in various interest rate environments. Based upon
the Company's interest rate shock simulations, net interest income is expected
to decline approximately 5.8% with a 200 basis point instantaneous increase to
interest rates and decline approximately 1.7% with a 200 basis point
instantaneous decrease in rates. Management has a target of minimizing the
decline in net interest income to no more than 10% given a 200 basis point
instantaneous decrease in rates.
 
    The preceding sensitivity analysis does not represent a forecast and should
not be relied upon as being indicative of expected operating results. These
hypothetical estimates are based upon numerous assumptions including: the nature
and timing of interest rate levels including the yield curve shape, prepayments
on loans and securities, changes in deposit levels, pricing decisions on loans
and deposits, reinvestment/ replacement of asset and liability cashflows and
others. While assumptions are developed based upon current economic and local
market conditions, the Company cannot make any assurances as to the predictive
nature of these assumptions including how customer preferences or competitor
influences might change.
 
    Also, as market conditions vary from those assumed in the sensitivity
analysis, actual results will also differ due to prepayment/refinancing levels
likely deviating from those assumed, the varying impact of interest rate change
caps or floors on adjustable rate loans, depositor early withdrawals and product
preference changes, and other internal/external variables. Furthermore, the
sensitivity analysis does not reflect actions that management might take in
responding to or anticipating changes in interest rates.
 
    Management has taken several steps to reduce the positive gap of the Company
by lengthening the maturities in its investment portfolio and originating more
fixed rate assets that mature or reprice in balance with its interest bearing
liabilities. Management will continue to maintain a balance between its interest
earning assets and interest bearing liabilities in order to minimize the impact
on net interest income due to changes in market rates.
 
    The following table sets forth the distribution of the expected maturities
of the Company's interest-earning assets and interest-bearing liabilities as
well as the fair value of these instruments. Expected maturities are based on
contractual payments without effect being given for the estimated effect of
 
                                       59
<PAGE>
prepayments. Savings accounts and interest-bearing transaction accounts, which
have no stated maturity, are included in the one year or less maturity category.

                           SUPERVISION AND REGULATION
 
OVERVIEW
 
    The Company is a registered bank holding company under the BHC Act, and it
is subject to regulation, supervision and periodic examination by the Board of
Governors of the Federal Reserve System (the "Federal Reserve").
 
    As California state-licensed banks, the Banks are subject to regulation,
supervision and periodic examination by the DFI. Eldorado Bank also is subject
to regulation, supervision and periodic examination by the Federal Reserve,
because it is a member of the Federal Reserve System; Antelope Valley Bank is
not, and therefore is subject to regulation, supervision and periodic
examination at the federal level by the FDIC. The Banks' deposits are insured by
the FDIC to the maximum amount permitted by law, which is currently $100,000 per
depositor in most cases. The regulations of the DFI, Federal Reserve and FDIC
govern most aspects of the Banks' business and operations, including but not
limited to, the scope of their business, their investments, their reserves
against deposits, the nature and amount of collateral for certain loans, the
timing of availability of deposited funds, the issuance of securities, the
payment of dividends, bank expansion and bank activities, including real estate
development and insurance activities.
 
    The federal and state banking agencies have broad enforcement powers over
the Company and the Banks, including the power to impose substantial fines and
other civil and criminal penalties, to terminate deposit insurance and to
appoint a conservator or receiver for a bank under a variety of circumstances.
 
LIMITATIONS ON BANK HOLDING COMPANY ACTIVITIES
 
    With certain limited exceptions, the BHC Act requires every bank holding
company to obtain the prior approval of the Federal Reserve before undertaking
any of the following activities: (i) acquiring direct or indirect ownership or
control of any voting shares of another bank or bank holding company if, after
such acquisition, it would own or control more than 5% of any class of voting
shares (unless it already owns or controls the majority of such shares); (ii)
acquiring all or substantially all of the assets of another bank or bank holding
company; or (iii) merging or consolidating with another bank holding company.
The Federal Reserve will not approve any acquisition, merger or consolidation
that would have a substantially anti-competitive result, unless the
anti-competitive effects of the proposed transaction are clearly outweighed in
the public interest by the probable effect of the transaction in meeting the
convenience and needs of the community to be served. The Federal Reserve also
considers financial and managerial factors, as well as compliance with the
Community Reinvestment Act of 1977 (the "CRA"), in reviewing proposed
acquisitions or mergers.
 
    With certain exceptions, the BHC Act also prohibits a bank holding company
from acquiring or retaining direct or indirect ownership or control of voting
securities or assets of any company that is not a bank or bank holding company,
or from engaging directly or indirectly in activities other than those of
banking, managing or controlling banks or providing services for its
subsidiaries. The principal exceptions to those prohibitions involve certain
non-bank activities, which, by statute or by Federal Reserve regulation or
order, have been identified as activities closely related to the business of
banking or of managing or controlling banks. In making that determination, the
Federal Reserve considers whether the performance of such activities by a bank
holding company can be expected to produce benefits to the public such as
greater convenience, increased competition or gains in efficiency, that can be
expected to outweigh the risks of possible adverse effects such as undue
concentration of resources, decreased or unfair competition, conflicts of
interest or unsound banking practices.
 
    Furthermore, under the BHC Act, a bank subsidiary of a bank holding company
is prohibited from engaging in certain tie-in arrangements in connection with
any extension of credit, lease or sale of property or furnishing of services.
For example, in general, the Banks may not condition the extension of credit to
a
 
                                       61
<PAGE>
customer upon the customer obtaining other services from the Company or any of
its other subsidiaries or upon the customer promising not to obtain services
from a competitor.
 
CAPITAL ADEQUACY REQUIREMENTS
 
    The Company and the Banks are subject to regulations governing capital
adequacy, which incorporate both risk-based and leverage capital requirements.
Those risk-based and leverage capital guidelines set total capital requirements
and define capital in terms of "core capital elements," or Tier 1 capital, and
"supplementary capital elements," or Tier 2 capital. The sum of an institution's
Tier 1 capital and its Tier 2 capital is the institution's "qualifying" total
capital for purposes of determining capital adequacy. Banks and bank holding
companies are required to maintain a minimum ratio of qualifying total capital
to risk-weighted assets of 8%, at least one-half of which must be in the form of
Tier 1 capital. In order to determine an asset's risk weight, the asset is
multiplied by the applicable risk weight percentage assigned by the federal
regulators to that asset.
 
    The Federal Reserve and the FDIC have established a minimum leverage ratio
of Tier 1 capital to total assets (the "Tier 1 Leverage Ratio") of 3% for bank
holding companies and banks that have received the highest composite regulatory
rating and for bank holding companies and member banks that have implemented the
Federal Reserve's risk-based capital measure for market risk. All other bank
holding companies and banks are required to maintain a Tier 1 Leverage Ratio of
at least 4%. Banking organizations with supervisory, financial, operational, and
managerial weaknesses, as well as organizations experiencing significant growth,
are expected to maintain capital ratios above the minimum levels. If the Company
or one of the Banks fails to maintain the required capital levels, its primary
federal regulator may issue a capital directive to require an increase in
capital levels.
 
    The Federal Reserve's and the FDIC's risk-based capital standards require
the Company and the Banks to take adequate account of concentrations of credit
and the risks of non-traditional activities. Concentrations of credit refers to
situations where a lender has a relatively large proportion of loans involving
one borrower, industry, location, collateral or loan type. Non-traditional
activities are considered those that have not customarily been part of the
banking business but that start to be conducted as a result of developments in,
for example, technology or financial markets. Institutions with high or
inordinate levels of risk are required to operate with higher minimum capital
ratios. The Federal Reserve and the FDIC also review an institution's management
of concentrations of credit risk for adequacy and consistency with safety and
soundness standards regarding internal controls, credit underwriting or other
operational and managerial areas.
 
    The Federal Reserve's risk-based capital regulations also include standards
for evaluating a member bank's exposure to economic declines based upon interest
rate risk. Interest rate risk is the exposure of a bank's current and future
earnings and equity capital arising from adverse movements in interest rates.
While interest rate risk is inherent in a bank's role as financial intermediary,
it introduces volatility to a bank's earnings and to the economic value of a
bank. The Federal Reserve will consider the institution's historical financial
performance and its earnings exposure to interest rate movements, as well as
qualitative factors such as the adequacy of the institution's internal interest
rate risk management. The Federal Reserve and the other banking agencies have
elected not to pursue a standardized measure and explicit capital charge for
interest rate risk.
 
    In certain circumstances, the federal regulators may determine that the
capital ratios for a bank must be maintained at levels that are higher than the
minimum levels required by guidelines or regulations. In particular, bank
holding companies and banks contemplating significant expansion proposals are
expected to maintain capital levels significantly above the minimum levels
required by the guidelines. Neither the Company nor either of the Banks has been
advised by any bank regulatory agency that it must maintain a specific Tier 1
Leverage Ratio in excess of the minimum levels specified in the capital
guidelines, although in connection with the application to the Federal Reserve
for approval to complete the acquisition of
 
                                       62
<PAGE>
Eldorado Bancorp, the Company was required to have a pro forma Tier 1 Leverage
Ratio of 6.0%, a Total Risk-Weighted Ratio of 10.0% and a Tier 1 Risk-Weighted
Ratio of 6.0% as of the end of the quarter preceding the closing of that
acquisition. In addition, in connection with the acquisition of Eldorado
Bancorp, the Company also agreed not to incur any debt without the prior
approval of the Federal Reserve.
 
REGULATORY RESTRICTIONS ON DISTRIBUTIONS TO SHAREHOLDERS
 
    STOCK REDEMPTIONS.  Bank holding companies, such as the Company, are
required to give the Federal Reserve notice of any purchase or redemption of
their outstanding equity securities if the gross consideration for the purchase
or redemption, when combined with the net consideration paid for all such
purchases or redemptions during the preceding 12 months, is equal to 10% or more
of the bank holding company's consolidated net worth. The Federal Reserve may
disapprove such a purchase or redemption if it determines that the proposal
would constitute an unsafe or unsound practice or would violate any law,
regulation, Federal Reserve order, directive, or any condition imposed by, or
written agreement with, the Federal Reserve. A bank holding company whose
capital ratios exceed the thresholds for "well capitalized" banks on a
consolidated basis is exempt from the foregoing requirement if it (i) will
remain well-capitalized following the purchase or redemption, (ii) is
well-managed and (iii) is not the subject of any unresolved supervisory issues.
In connection with the acquisition of the Eldorado Bancorp, the Company agreed
that it will not redeem, retire or repurchase any of its preferred stock without
the prior approval of the Federal Reserve.
 
    DIVIDENDS.  Federal Reserve policies declare that a bank holding company
should not pay cash dividends on its common stock unless its net income is
sufficient to fund fully each dividend, and its prospective rate of earnings
retention after the payment of such dividend appears consistent with its capital
needs, asset quality and overall financial condition. In connection with the
acquisition of Eldorado Bancorp, the Company agreed that it will not pay
dividends on common stock without the prior approval of the Federal Reserve.
 
    The Company is a legal entity separate and distinct from each of the Banks.
Substantially all of the Company's revenues and cash flow, including funds
available for the payment of dividends and other operating expenses, consists of
dividends paid to the Company by the Banks. There are statutory and regulatory
limitations on the amount of dividends that may be paid to the Company by the
Banks. Dividends payable by each of the Banks are restricted under California
law to the lesser of that Bank's retained earnings, or that Bank's net income
for the latest three fiscal years, less distributions previously declared by
that Bank during that period, or, with the approval of the DFI, to the greater
of the retained earnings of that Bank, the net income of that Bank for its last
fiscal year or the net income of that Bank for its current fiscal year. In
connection with the acquisition of Eldorado Bancorp, Eldorado Bank paid a
dividend of $14 million, which exceeded Eldorado Bank's net income for the
latest three fiscal years. As a result, Eldorado Bank will require the approval
of the DFI with respect to the payment of any dividend and in no event may
Eldorado Bank pay dividends in excess of the greater of Eldorado Bank's retained
earnings, the net income of Eldorado Bank for its last fiscal year and the net
income of Eldorado Bank for its current fiscal year. No such dividend was paid
in connection with the acquisition of Antelope Valley Bank.
 
    The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
generally prohibits depository institutions from making capital distributions
(including payment of dividends), or paying any management fee to its holding
company if the depository institution would thereafter be "undercapitalized" for
regulatory purposes.
 
    In addition, Federal Reserve regulations limit the payment of dividends by
Eldorado Bank as a state member bank. Under Federal Reserve regulations,
dividends may not be paid unless both undivided profits and earnings limitations
have been met. First, no dividend may be paid if it would result in a withdrawal
of
 
                                       63
<PAGE>
capital or exceed the bank's undivided profits as reported in its most recent
Report of Condition and Income, without the prior approval of the Federal
Reserve and two-thirds of the shareholders of each class of stock outstanding.
Second, a state member bank may not pay a dividend without the prior approval of
the Federal Reserve if the total of all dividends declared in one year exceeds
the total of net income for that year, plus its retained net income for the
preceding two calendar years.
 
    The payment of dividends on capital stock by the Company and the Banks may
be limited by other factors, including applicable regulatory capital
requirements and broad enforcement powers of the federal regulatory agencies.
Each of the Federal Reserve, the FDIC and the DFI have broad authority to
prohibit the Company and the Banks from engaging in practices that the banking
agency considers to be unsafe or unsound, including the payment of dividends
under certain circumstances.
 
    The regulations and restrictions on payment of dividends may limit the
Company's ability to obtain funds from the Banks for its cash needs, including
funds for payment of interest and operating expenses and dividends.
 
TRANSACTIONS WITH AFFILIATES
 
    The Banks are subject to restrictions under federal law that limit certain
transactions with the Company, each other and the Company's banking and
non-banking affiliates, including extensions of credit, investments or asset
purchases. Extensions of credit and certain other "covered" transactions by any
member bank with any one affiliate are limited in amount to 10% of such bank's
capital stock and surplus and with its affiliates, in the aggregate, are limited
in amount to 20% of capital stock and surplus and loans and other extensions of
credit must be fully secured in accordance with applicable regulations. Federal
law also provides that covered transactions with affiliates must be made on
substantially the same terms and under substantially the same circumstances as,
and, in the case of credit transactions, following credit underwriting
procedures that are no less stringent than, those prevailing at the time for
comparable transactions involving other non-affiliated companies, or, in the
absence of comparable transactions, on terms and under circumstances, including
credit standards, that in good faith would be offered to, or would apply to,
non-affiliates. The purchase of low quality assets from affiliates is generally
prohibited.
 
CROSS-GUARANTEE AND HOLDING COMPANY LIABILITY
 
    Any FDIC-insured depository institution may be liable for any loss incurred
by the FDIC, or any loss that the FDIC reasonably anticipates incurring, in
connection with (i) the default of any commonly controlled FDIC-insured
depository institution or (ii) any assistance provided by the FDIC to a commonly
controlled FDIC-insured depository institution in danger of default. Any
obligation or liability owed by a subsidiary depository institution to its
parent company is subordinate to the subsidiary institution's cross-guarantee
liability to the FDIC. As of the date of this prospectus, the Banks are the
Company's only insured depository institution subsidiaries.
 
    Federal Reserve policy requires bank holding companies to serve as a source
of financial strength to their subsidiary banks by standing ready to use
available resources to provide adequate capital funds to subsidiary banks during
periods of financial stress or adversity.
 
    In the event of a bank holding company's bankruptcy under Chapter 11 of the
U.S. Bankruptcy Code, the trustee will be deemed to have assumed, and is
required to cure immediately, any deficit under any commitment by the debtor to
any of the federal banking agencies to maintain the capital of an insured
depository institution, and any claim for a subsequent breach of such obligation
will generally have priority over most other unsecured claims.
 
                                       64

PROMPT CORRECTIVE ACTION PROVISIONS
 
    FDICIA amended the Federal Deposit Insurance Act ("FDIA") to establish a
format for closer monitoring of insured depository institutions and to enable
prompt corrective action by regulators when an institution begins to experience
financial difficulty. The general thrust of those provisions is to impose
greater scrutiny and more restrictions on institutions as they have decreasing
levels of capitalization. FDICIA establishes five capital categories: "well
capitalized," "adequately capitalized," "undercapitalized," "significantly
undercapitalized," and "critically undercapitalized." Under the regulations, a
"well capitalized" institution has a ratio of total capital to total
risk-weighted assets ("Total Risk-Weighted Ratio") of at least 10.0%, a ratio of
Tier 1 capital to total risk-weighted assets ("Tier 1 Risk-Weighted Ratio") of
at least 6.0%, a Tier 1 Leverage Ratio of at least 5.0% and is not subject to
any written order, agreement or directive; an "adequately capitalized"
institution has a Total Risk-Weighted Ratio of at least 8.0%, a Tier 1
Risk-Weighted Ratio of at least 4.0% and a Tier 1 Leverage Ratio of at least
4.0% (or 3.0% if the institution has received the highest regulatory rating and
is not experiencing significant growth), but does not otherwise qualify as "well
capitalized." An "undercapitalized" institution fails to meet one of the three
minimum capital requirements for "adequately capitalized" banks. A
"significantly undercapitalized" institution has a Total Risk-Weighted Ratio of
less than 6.0%, a Tier 1 Risk-Weighted Ratio of less than 3.0% and/or a Tier 1
Leverage Ratio of less than 3.0%. A "critically undercapitalized" institution
has a ratio of tangible equity to assets of 2.0% or less. Under certain
circumstances, a "well capitalized," "adequately capitalized" or
"undercapitalized" institution may be required to comply with supervisory
actions as if the institution was in the next lowest capital category.
 
    Undercapitalized depository institutions are subject to restrictions on
borrowing from the Federal Reserve. In addition, undercapitalized depository
institutions are subject to growth and activity limitations and are required to
submit "acceptable" capital restoration plans. The federal banking agencies may
not accept a capital plan without determining, among other things, that the plan
is based on realistic assumptions and is likely to succeed in restoring the
depository institution's capital and may require guarantees from the depository
institution's holding company, if any. If a depository institution fails to
submit an acceptable plan, it is treated as if it is significantly
undercapitalized and ultimately may be placed into conservatorship or
receivership.
 
    Significantly undercapitalized depository institutions may be subject to a
number of additional requirements and restrictions, including orders to sell
sufficient voting stock to become adequately capitalized, more stringent
requirements to reduce total assets, cessation of receipt of deposits from
correspondent banks, prohibitions on dividends to the holding company and
requirements that the holding company divest its bank subsidiary, in certain
instances. Subject to certain exceptions, critically undercapitalized depository
institutions must have a conservator or receiver appointed for them within a
certain period after becoming critically undercapitalized.
 
SAFETY AND SOUNDNESS STANDARDS
 
    The federal banking agencies have issued "safety and soundness" standards
for banks. The standards, which were issued in the form of guidelines rather
than regulations, relate to internal controls, information systems, internal
audit systems, loan underwriting and documentation, compensation, interest rate
exposure, asset growth, compensation, fees and benefits. Examiners assign a
formal supervisory rating to the adequacy of an institution's risk management
processes, including its internal controls. In general, the standards are
designed to assist the federal banking agencies in identifying and addressing
problems at insured depository institutions before capital becomes impaired. If
an institution fails to meet these standards, the appropriate federal banking
agency may require the institution to submit a compliance plan. Failure to
submit an acceptable compliance plan may result in enforcement proceedings.

LIMITATIONS ON BROKERED DEPOSIT TAKING
 
    FDICIA provides that a bank may not accept, renew or roll over brokered
deposits unless (i) it is "well capitalized" or (ii) it is adequately
capitalized and receives a waiver from the FDIC permitting it to accept brokered
deposits. FDIC regulations define brokered deposits to include any deposit
obtained, directly or indirectly, from any person engaged in the business of
placing deposits with, or selling interests in deposits of, an insured
depository institution, as well as any deposit obtained by a depository
institution that is not "well capitalized" for regulatory purposes by offering
rates significantly higher (generally more than 75 basis points) than the
prevailing interest rates offered by depository institutions in such
institution's normal market area. In addition, FDICIA provides that institutions
that are ineligible to accept brokered deposits are ineligible for pass-through
deposit insurance for employee benefit plan deposits.
 
PREMIUMS FOR DEPOSIT INSURANCE
 
    As previously stated, the Banks' deposits are insured by the FDIC to the
maximum amount permitted by law, which is currently $100,000 per depositor in
most cases. FDIC insurance premiums are assessed on a risk-based system, meaning
that the amount of a depositary institution's premium depends on its risk
classification. To arrive at a depository institution's risk-based assessment,
the FDIC places it in one of nine risk categories using a two-step process based
first on capital ratios and then on relevant supervisory information. Each
institution is assigned to one of three capital categories: "well capitalized,"
"adequately capitalized," or "undercapitalized." A well capitalized institution
is one that has a Total Risk-Weighted Ratio of at least 10.0%, a Tier 1
Risk-Weighted Ratio of at least 6.0% and a Tier 1 Leverage Ratio of at least
5.0%. An adequately capitalized institution has at least an Total Risk-Weighted
Ratio of at least 8.0%, a Tier 1 Risk-Weighted Ratio of at least 4.0% and a Tier
1 Leverage Ratio of at least 4.0%. An undercapitalized institution is one that
does not meet either of the above definitions. The FDIC also assigns each
institution to one of three supervisory subgroups based on an evaluation of the
risk posed by the institution (group "A" institutions being perceived to present
the least risk and group "C" institutions being perceived to present the
greatest risk). The FDIC makes this evaluation based on examinations by the
institution's primary federal or state regulator, statistical analyses of
financial statements, and other information relevant to gauging the risk posed
by the institution. Those supervisory evaluations modify premium rates within
each of the three capital groups, resulting in a matrix of nine separate
assessment categories.
 
    In September 1996, legislation was enacted to recapitalize the FDIC's
Savings Association Insurance Fund to provide for the payment of certain future
obligations of the Fund and, ultimately, to merge the Fund and its counterpart,
the Bank Insurance Fund, into a single insurance fund called the Deposit
Insurance Fund. The deposits of Eldorado Bank, Liberty National Bank and San
Dieguito National Bank were insured by the Bank Insurance Fund; the deposits of
Commerce Security Bank were insured by the Savings Association Insurance Fund.
Since the merger of Eldorado Bank, Liberty, San Dieguito and Commerce Security,
the deposits of Eldorado Bank have been insured by the Savings Association
Insurance Fund and the Bank Insurance Fund generally in proportion to the
pre-combination allocation of deposits among those banks.
 
    Under the legislation, each depository institution whose deposits are
insured by the Savings Association Insurance Fund (with limited exceptions) was
required to pay a one-time "special assessment" into Savings Association
Insurance Fund in the amount of approximately $.66 for each $100 of deposits
that the institution had as of a given measurement date. The special assessment
was intended to cause, and has caused, Savings Association Insurance Fund's
assets to reach the targeted "reserve ratio" of 1.25% of insured deposits. As a
consequence, the FDIC has been able to reduce the normal, periodic deposit
insurance premiums charged to Savings Association Insurance Fund-insured
institutions to levels consistent with those charged to Bank Insurance
Fund-insured institutions. For well capitalized and well managed institutions,
those rates can be as low as a statutory minimum of $2,000 per year.
 
                                       66
<PAGE>
    Under the legislation, however, the FDIC is obligated to levy ongoing
special assessments on all insured institutions in order to pay debt service on
certain bonds issued in connection with the resolution of financially troubled
savings associations prior to 1989. Through 1999, institutions insured through
the Savings Association Insurance Fund will pay those special assessments at an
annual rate five times that paid by institutions insured through the Bank
Insurance Fund. While the precise rate will vary from period to period,
initially the rate for institutions insured through the Savings Association
Insurance Fund will be $.064 per $100 of deposits and the rate for institutions
insured through the Bank Insurance Fund will be $.0128 per $100 of deposits.
Beginning in January 2000, the rates paid by institutions insured by each fund
will be equalized. Unlike the one-time special assessment discussed above, it is
expected that those ongoing special assessments will be recorded as expenses
during the period for which they are assessed.
 
    The current deposit assessment matrices for insured depository institutions,
are as follows (in cents per $100 of deposits):

(a) Subject to a statutory minimum annual assessment of $2,000.
 
    For purposes of the assessment of deposit insurance premiums for the
six-month period ending June 30, 1999, Eldorado Bank will be assessed as an
adequately capitalized bank and Antelope Valley Bank will be assessed as a well
capitalized bank. FDIC regulations prohibit disclosure of the "supervisory
subgroup" to which an insured institution is assigned. Eldorado Bank's insurance
assessment paid during the year ended December 31, 1998 was $354,000, and
Antelope's insurance assessment paid during the year ended December 31, 1998 was
$22,000.
 
RESTRICTIONS ON CHANGES OF CONTROL
 
    Subject to certain limited exceptions, no company (as defined in the BHC
Act) or individual can acquire control of a bank holding company, such as the
Company, without the prior approval or non-disapproval, as the case may be, of
the Federal Reserve. Prior approval of the Federal Reserve would be required for
an acquisition of control of the Company by a "company" as defined in the BHC
Act. In general, Federal Reserve regulations provide that "control" means the
power to vote 25% or more of any class of voting stock, the power to control in
any manner the election of a majority of the board of directors
 
                                       67
<PAGE>
or the power to exercise, directly or indirectly, a controlling influence over
management or policies as determined by the Federal Reserve. As part of such
acquisition, the company would be required to register as a bank holding company
(if not already so registered) and have its business activities limited to those
activities that the Federal Reserve determines to be so closely related to
banking as to be a proper incident thereof. See "-- Limitations on Bank Holding
Company Activities." Federal Reserve regulations also provide that there is a
presumption that any company that owns less than 5% of any class of voting
securities of a bank holding company does not have control over that company.
 
    Any individual (or group of individuals acting in concert) who intends to
acquire control of a bank holding company, such as the Company, generally must
give 60 days prior notice to the Federal Reserve under regulations promulgated
pursuant to the Change in Bank Control Act of 1978. Control for the purpose of
those regulations is presumed to exist if, among other things, an individual
owns, controls or has the power to vote 25% or more of a class of voting stock
of the bank or bank holding company, or an individual owns, controls or has the
power to vote 10% or more of a class of voting stock of the bank or bank company
and (i) the company's shares are registered pursuant to Section 12 of the
Exchange Act, or (ii) such person would be the largest shareholder of the
institution. The statute and underlying regulations authorize the Federal
Reserve to disapprove the proposed transaction based on the evaluation of
certain specified factors, including, without limitation, competition,
management and financial condition. The Company's common stock is currently
registered under Section 12 of the Exchange Act.
 
    Under California law, any individual, entity or group that intends to
acquire direct or indirect control of a bank organized under California law must
obtain the prior approval of the Commissioner of Financial Institutions for the
State of California. "Control" for purposes of California law means the power to
vote 25% or more of any class of voting securities or the power to direct or
cause the direction of management and policies in any manner.
 
CONSUMER PROTECTION LAWS AND REGULATIONS
 
    OVERVIEW.  In recent years, the bank regulatory agencies have focused
greater attention on compliance with consumer protection laws and their
implementing regulations. Examination and enforcement have become more intense
in nature, and insured institutions have been advised to monitor carefully
compliance with various consumer protection laws and their implementing
regulations. The Banks are subject to many federal consumer protection statutes
and regulations including, but not limited to, the Community Reinvestment Act,
the Truth in Lending Act, the Fair Housing Act, the Equal Credit Opportunity
Act, the Real Estate Settlement Procedures Act, and the Home Mortgage Disclosure
Act. Due to heightened regulatory concern related to compliance with those acts,
the Banks may incur additional compliance costs or be required to expend
additional funds for investments in their local communities. In addition, the
federal regulators will take into account the compliance record of the Banks in
evaluating the adequacy of their management in connection with applications for
mergers and acquisitions. An adverse compliance rating can result in a material
delay or denial of such an application. As a result of the relatively high
volume of residential mortgage loans and applications processed by Eldorado
Bank's Mortgage Division, Eldorado Bank may have greater exposure to consumer
protection compliance issues than many of its peer group banks. As part of its
ongoing compliance program, Eldorado Bank has outsourced its internal audit of
the Mortgage Division to a consulting firm.
 
    THE COMMUNITY REINVESTMENT ACT.  The Community Reinvestment Act is intended
to encourage insured depository institutions, while operating safely and
soundly, to help meet the credit needs of their communities. The act
specifically directs the federal regulatory agencies, in examining insured
depository institutions, to assess their record of helping to meet the credit
needs of their entire community, including low- and moderate-income
neighborhoods, consistent with safe and sound banking practices. It further
requires the agencies to take a financial institution's record of meeting its
community's credit needs into account when evaluating applications for, among
other things, domestic branches, consummating mergers or acquisitions, or
holding company formations.
 
                                       68
<PAGE>
    The bank regulatory agencies use the assessment factors from the Community
Reinvestment Act to rate financial institutions. The ratings range from a high
of "outstanding" to a low of "substantial noncompliance." Eldorado Bank received
a satisfactory CRA rating in its 1998 examination. Antelope Valley Bank was
examined most recently in 1995 and received a satisfactory CRA rating.
 
    THE EQUAL CREDIT OPPORTUNITY ACT.  The Equal Credit Opportunity Act
prohibits discrimination against an applicant in any credit transaction, whether
for consumer or business purposes, on the basis of race, color, religion,
national origin, sex, marital status, age (except in limited circumstances),
receipt of income from public assistance programs or good faith exercise of any
rights under the Consumer Credit Protection Act. In addition to prohibiting
outright discrimination on any of the impermissible bases listed above, an
effects test has been applied to determine whether a violation of the act has
occurred. This means that if a creditor's actions have had the effect of
discriminating, the creditor may be held liable -- even when there is no intent
to discriminate. In addition to actual damages, the Equal Credit Opportunity Act
permits regulatory agencies to take enforcement actions and provides for
punitive damages of up to $10,000 in individual lawsuits and up to the lesser of
$500,000 or 1.0% of the creditor's net worth in class action suits. Successful
complainants may also be entitled to an award of court costs and attorneys'
fees.
 
    THE FAIR HOUSING ACT.  The Fair Housing Act regulates many of the Banks'
lending practices, including making it unlawful for any lender to discriminate
in its housing-related lending activities against any person because of race,
color, religion, national origin, sex, handicap or familial status. The Fair
Housing Act is broadly written and has been broadly interpreted by the courts. A
number of lending practices have been found to be, or may be considered, illegal
under the Fair Housing Act, including some that are not specifically mentioned
in the act itself. Among those practices that have been found to be, or may be
considered, illegal under the Fair Housing Act are the following: declining a
loan for the purposes of racial discrimination; making excessively low
appraisals of property based on racial considerations; pressuring, discouraging,
or denying applications for credit on a prohibited basis; using excessively
burdensome qualification standards for the purpose or with the effect of denying
housing to minority applicants; imposing on minority loan applicants more
onerous interest rates or other terms, conditions, or requirements; and racial
steering, or deliberately guiding potential purchasers to or away from certain
areas because of race.
 
    The Fair Housing Act allows a person who believes that he or she has been
discriminated against to file a complaint with the Department of Housing and
Urban Development. Aggrieved persons also may initiate a civil action. In
addition, the Fair Housing Act permits the Attorney General of the United States
to commence a civil action if the Attorney General of the United States has
reasonable cause to believe that a person has been discriminated against in
violation of the Fair Housing Act. Penalties for violation of the Fair Housing
Act include actual damages suffered by the aggrieved person and injunctive or
other equitable relief. The courts also may assess civil penalties.
 
    THE TRUTH IN LENDING ACT.  The Truth in Lending Act is designed to ensure
that credit terms are disclosed in a meaningful way so that consumers may
compare credit terms more readily and knowledgeably. As a result of the act, all
creditors must use the same credit terminology and expressions of rates, the
annual percentage rate, the finance charge, the amount financed, the total of
payments and the payment schedule.
 
    Violations of the Truth in Lending Act may result in regulatory sanctions
and in the imposition of both civil and, in the case of willful violations,
criminal penalties. Further, under certain circumstances, the Truth in Lending
Act and Federal Reserve Regulation Z provide a consumer with a right of
rescission, which relieves the consumer of the obligation to pay amounts to the
creditor or to a third party in connection with the offending transaction,
including finance charges, application fee, commitment fees, title search fees
and appraisal fees.
 
                                       69
<PAGE>
    The Truth in Lending Act requirements are complex and even inadvertent
noncompliance could result in civil liability or other penalties. In recent
years, a significant number of individual claims and purported consumer class
action claims have been commenced against a number of financial institutions,
their subsidiaries, and other mortgage lending companies, seeking civil
statutory and actual damages and rescission under the act, as well as remedies
for alleged violations of various state unfair trade practices acts and
restitution for unjust enrichment with respect to mortgage loan transactions.
 
    THE HOME MORTGAGE DISCLOSURE ACT.  The Home Mortgage Disclosure Act grew out
of public concern over credit shortages in certain urban neighborhoods. One
purpose of the Home Mortgage Disclosure Act is to provide public information
that will help show whether financial institutions are serving the housing
credit needs of the neighborhoods and communities in which they are located. The
Home Mortgage Disclosure Act also includes a "fair lending" aspect that requires
the collection and disclosure of data about applicant and borrower
characteristics as a way of identifying possible discriminatory lending patterns
and enforcing anti-discrimination statutes. The Home Mortgage Disclosure Act
requires institutions to report data regarding applications for loans for the
purchase or improvement of one-to-four family and multifamily dwellings, as well
as information concerning originations and purchases of such loans. Federal bank
regulators rely, in part, upon data provided under the Home Mortgage Disclosure
Act to determine whether depository institutions engage in discriminatory
lending practices.
 
    Compliance with the Home Mortgage Disclosure Act and implementing
regulations is enforced by the appropriate federal banking agency, or in some
cases, by the Department of Housing and Urban Development. Administrative
sanctions, including civil money penalties, may be imposed by supervisory
agencies for violations. The Home Mortgage Disclosure Act requires depository
institutions to compile and disclose certain information with respect to
mortgage loans, including the census tract, income level, racial characteristics
and gender of the borrower or potential borrower. That data may have a material
effect on the regulators' assessment of an institution, particularly in
connection with an institution's application to enter into a merger or to
acquire one or more branches.
 
    THE REAL ESTATE SETTLEMENT PROCEDURES ACT.  The Real Estate Settlement
Procedures Act requires lenders to provide borrowers with disclosures regarding
the nature and cost of real estate settlements. It also prohibits certain
abusive practices, such as kickbacks, and places limitations on the amount of
escrow accounts. Violations of the Real Estate Settlement Procedures Act may
result in imposition of penalties, including (1) civil liability equal to three
times the amount of any charge paid for the settlement services or civil
liability of up to $1,000 per claimant, depending on the violation; (2) awards
of court costs and attorneys' fees; and (3) fines of not more than $10,000 or
imprisonment for not more than one year, or both. A significant number of
individual claims and purported consumer class action claims have been commenced
against financial institutions and other mortgage lending companies alleging
violations of the escrow account rules and seeking civil damages, court costs
and attorneys' fees.
 
CERTAIN OTHER ASPECTS OF FEDERAL AND STATE LAW
 
    The Banks are also subject to federal and state statutory and regulatory
provisions covering, among other things, security procedures, currency and
foreign transactions reporting, insider transactions, management interlocks,
loan interest rate limitations, electronic funds transfers, funds availability
and truth-in-savings disclosures.
 
FEDERAL SECURITIES LAWS
 
    The common stock is registered under Section 12(g) of the Exchange Act, and
the Company is obligated to file periodic reports with the Securities and
Exchange Commission pursuant to Section 13(a) of the Exchange Act and is subject
to the other informational requirements of the Exchange Act, including the
obligation to file proxy statements and other information with the Commission.

INTERSTATE BANKING AND BRANCHING
 
    The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 (the
"Interstate Banking Act") regulates at the federal level the interstate
activities of banks and bank holding companies and establishes a framework for
nationwide interstate banking and branching. In order to implement certain
provisions of the Interstate Banking Act, California enacted the Caldera,
Weggeland, and Killea California Interstate Banking and Branching Act of 1995.
 
    The Interstate Banking Act permits a bank that is located in one state and
that does not already have a branch office in a second state to establish a
branch office in the second state, subject to that state's laws, by (i)
acquisition of, or merger with, a bank located in the second state, (ii)
acquisition of a branch office of a bank in the second state or (iii)
establishment of a DE NOVO branch office in the second state. By means of the
Caldera Weggeland Act, the State of California permits out of state banks to
establish California branch offices only by acquisition of, or merger with, a
California bank that has been in existence for at least five years. The Caldera
Weggeland Act expressly prohibits an out-of-state bank that does not already
have a California branch office from (i) purchasing a branch office of a
California bank or (ii) establishing a California branch office on a DE NOVO
basis.
 
    The Interstate Banking Act also permits an adequately capitalized and
adequately managed bank holding company to acquire banks located in any state,
provided that following the acquisition, the acquiror will not control more than
10.0% of deposits held by insured depository institutions nationwide or 30.0% of
deposits held by insured depository institutions in any one state, provided
further that if the state bank supervisor of the state in which the acquiror
will hold in excess of 30.0% of deposits approves the acquisition, the
acquisition will not be prohibited. The Caldera Weggeland Act authorizes the
California Commissioner of Financial Institutions to approve an interstate
acquisition in which the acquiror would control more than 30.0% of deposits held
by insured financial institutions in California if the Commissioner finds that
the transaction is consistent with public convenience and advantage in
California.
 
    The Interstate Banking Act authorizes banks to establish agency
relationships between subsidiaries of a bank holding company. The Caldera
Weggeland Act is more expansive in that it permits California banks, with the
approval of the Commissioner, to establish agency relationships with both
affiliated and unaffiliated FDIC-insured banks and savings associations.
 
    As a result of the Interstate Banking Act and the Caldera Weggeland Act, the
Company and the Banks face competition from out-of-state financial institutions
in addition to competition from in-state institutions. It is not possible to
evaluate, however, what specific effect or, if any, the Interstate Banking Act
and the Caldera Weggeland Act have had or will have on the Company or the
competitive environment in which it operates.
 
EFFECT OF GOVERNMENTAL POLICIES AND LEGISLATION
 
    GENERAL.  Banking is a business that depends on rate differentials. In
general, the difference between the interest rate paid by one of the Banks on
its deposits and its other borrowings and the interest rate received by that
Bank on loans extended to its customers and securities held in its portfolio
comprise the major portion of the Company's earnings. These rates are highly
sensitive to many factors that are beyond the control of the Company.
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
Federal Reserve. The Federal Reserve can and does implement national monetary
policies (with objectives such as curbing inflation and combating recession) by
its open-market operations in United States Government securities, by its
control of the discount rates applicable to
 
                                       71
<PAGE>
borrowings by depository institutions and by adjusting the required level of
reserves for financial institutions subject to its reserve requirements. The
actions of the Federal Reserve in these areas influence the growth of bank
loans, investments and deposits and also affect interest rates charged on loans
and paid on deposits. As demonstrated in the past, the Federal Reserve's
policies regarding interest rates have a significant effect on the operating
results of commercial banks and are expected to continue to do so in the future.
The nature and effect of any future changes in monetary policies is not
predictable.
 
    From time to time, legislation is enacted that 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 frequently are made in Congress, in the California legislature and
before various bank regulatory and other professional agencies. For example,
legislation was introduced in Congress that would repeal the current statutory
restrictions on affiliations between commercial banks and securities firms.
Under the proposed legislation, bank holding companies would be allowed to
control both a commercial bank and a securities affiliate, which could engage in
the full range of investment banking activities, including corporate
underwriting. The likelihood of any major legislative changes and the effect
such changes might have on the Company are impossible to predict.
 
    RELIANCE ON SBA PROGRAMS.  A significant portion of Eldorado Bank business
consists of originating and servicing loans under the programs of the U.S. Small
Business Administration. See "Business -- Products and Services -- Community
Banking Division." Significant cuts in or other adverse changes to Small
Business Administration programs would likely have a material adverse effect on
the Company. See "Risk Factors -- Concentration in SBA lending -- Changes in SBA
regulations could reduce our SBA loan originations and revenues, which are
significant."
 
    In 1995, Congress passed the Small Business Lending Enhancement Act of 1995.
The act reduced the amount of the subsidy to borrowers inherent in the Small
Business Administration's guaranty of loans under its various programs, thus
causing the Small Business Administration to increase the fees it charges for
its guarantee. The actual payments by the Small Business Administration on its
guaranties plus the cost of program administration have historically exceeded
the aggregate guarantee fees collected by the Small Business Administration. At
the same time, however, by reducing the per-loan subsidy by an amount greater
than the reduction in the Small Business Administration's budget, the 1995 act
sought to increase the total number and dollar amount of loans that the Small
Business Adminstration would guarantee. While management has not discerned a
material decrease in the number or quality of borrowers seeking Small Business
Administration loans as a result of the increase in the guarantee fees charged
to borrowers, it is possible that such a decrease will occur over the long term.
In addition, there can be no assurance that the Small Business Administration
will not be discontinued in its entirety in the foreseeable future.

KELLER EMPLOYMENT AGREEMENT
 
    CAPACITY AND TERM.  In July 1996, the Company entered into an employment
agreement with Mr. Keller that was effective retroactive as of October 1, 1995.
The Company has agreed to employ Mr. Keller as the Company's senior most
executive officer, to nominate Mr. Keller to serve as a director of the Company
and to cause Mr. Keller to be elected as a director of each of the Company's
subsidiaries that is a depository institution or otherwise a "significant
subsidiary," as defined under SEC regulations. Mr. Keller's employment agreement
has a three-year term, ending on September 30, 2000, and will be renewed
automatically for successive one-year periods unless either the Company or Mr.
Keller gives the other notice at least one year prior to the end of the term or
any extension thereof.
 
    BASE SALARY.  Mr. Keller's base salary currently is $300,000. Mr. Keller's
base salary under the employment agreement depends upon the Company's
consolidated assets. For purposes of Mr. Keller's employment agreement, the
Company's consolidated assets are calculated as of the end of each of the
Company's fiscal quarters and are equal to the Company's average consolidated
assets for the six month period then ended calculated on a daily basis in
accordance with GAAP ("Average Consolidated Assets"), except that if the
Company's consolidated assets as of the end of a fiscal quarter vary by more
than 20 percent from the Average Consolidated Assets for the two consecutive
quarters ended as of that date, the Company's consolidated assets as of that
date are used for purposes of determining any adjustment to Mr. Keller's salary.
If, subsequent to an increase in Mr. Keller's base salary, the amount of Average
Consolidated Assets as of the end of any fiscal quarter is less than the most
recently applied asset threshold for determining Mr. Keller's salary, Mr.
Keller's base salary will be decreased, effective as of the beginning of the
quarter next following the measurement date, in accordance with the salary
schedule described above. The Company expects that as of March 31, 1999, the
Company's Average Consolidated Assets will exceed $1.2 billion, and Mr. Keller's
base salary will become $350,000. If the Company's Average Consolidated Assets
exceed $1.8 billion, Mr. Keller may request that the Compensation Committee of
the Company's Board of Directors (the "Committee") consider and make a
recommendation to the Company's Board of Directors whether it is appropriate to
increase his annual salary. Mr. Keller's base salary, as so determined, is
hereinafter referred to as his "Base Salary."
 
    RESTRICTED STOCK AWARDS.  Mr. Keller's employment agreement generally
obligates the Company to issue shares of restricted common stock (the
"Restricted Stock") to Mr. Keller whenever, during the term of the agreement,
the Company issues common stock or a Common Stock Equivalent (as defined in the
employment agreement), including shares of common stock issued in the CSB and
Eldorado Bancorp acquisitions. Pursuant to his employment agreement, Mr. Keller
will no longer be eligible to receive additional shares of Restricted Stock at
such time as the Company has Tier 1 capital in excess of $125.0 million. See
"Supervision and Regulation" for a definition of of Tier 1 capital. On a pro
forma basis giving effect to the offering, the Company had Tier 1 capital of
$85.3 million at December 31, 1998. In addition, Mr. Keller will not be entitled
to receive any Restricted Stock as a consequence of the sale of common stock or
a Common Stock Equivalent to DCG or director qualifying shares to any director
of a subsidiary of the Company or the award of employee stock options or the
issuance of common stock upon the exercise thereof.
 
                                       79
<PAGE>
    For so long as he is eligible, the number of shares of Restricted Stock that
will be issued to Mr. Keller will be equal to 3% of the sum of (x) the number of
shares of common stock then to be issued by the Company or, in the case of the
issuance of a Common Stock Equivalent, the number of shares of common stock that
such Common Stock Equivalent may be converted into or exchanged for, and (y) the
number of shares of Restricted Stock to be issued to Mr. Keller at that time. In
connection with the acquisition of Antelope, Mr. Keller received approximately
86,000 shares of Restricted Stock. Upon completion of the offering, Mr. Keller
will receive approximately 61,730 additional shares of Restricted Stock.
 
    Subject only to restrictions on transferability and forfeiture conditions
described below, Mr. Keller will have all the rights of a shareholder with
respect to the Restricted Stock, including, without limitation, the right to
vote the Restricted Stock and to receive any dividend or other distribution with
respect thereto. Prior to the end of Restricted Period (described below), Mr.
Keller may not sell, assign, transfer, pledge, hypothecate or otherwise encumber
or transfer the Restricted Stock, except as permitted by the Compensation
Committee. If Mr. Keller's employment under the employment agreement is
terminated for cause (as defined in the employment agreement) prior to the end
of the Restricted Period, or if Mr. Keller resigns from the Company during the
Restricted Period without the consent of the Board of Directors of the Company,
any Restricted Stock then outstanding will be forfeited to the Company without
any payment to Mr. Keller.
 
    In general, the "Restricted Period" will expire upon the earliest to occur
of the following events: (a) a Change in Control (as defined in Mr. Keller's
employment agreement) of the Company; (b) Mr. Keller's retirement from the
Company after attaining age 62; (c) the effective date of Mr. Keller's
resignation from the Company with the consent of the Board of Directors; (d) the
effective date of the expiration of Mr. Keller's employment agreement pursuant
to notice of non-renewal given by the Company; (e) the effective date of Mr.
Keller's termination of his employment agreement for cause (as defined in the
agreement); (f) the effective date of the termination of Mr. Keller's employment
by the Company due to a "disability" (as defined in the employment agreement);
or (g) Mr. Keller's death. In the case of Restricted Stock that is issued to Mr.
Keller as a consequence of the Company's issuance of a Common Stock Equivalent,
the Restricted Period will terminate on the later of (x) the date on which such
Common Stock Equivalent first becomes convertible into or exchangeable for
shares of common stock and (y) the earliest to occur of the events specified in
the immediately preceding sentence. If any Common Stock Equivalent is redeemed
in whole or in part by the Company prior to the date such Common Stock
Equivalent is convertible into or exchangeable for shares of common stock, upon
such redemption there shall be forfeited to the Company, without any payment to
Mr. Keller, a PRO RATA portion of the shares of Restricted Stock issued as a
consequence of the Company's sale of such Common Stock Equivalent.
 
    STOCK OPTION AWARDS.  As provided in Mr. Keller's employment agreement, the
Company's Board of Directors has adopted the 1997 Stock Option Plan (the "Option
Plan") pursuant to which the Board of Directors or the Committee has granted
stock options to Mr. Keller and others.
 
    Pursuant to Mr. Keller's employment agreement, promptly following the
adoption of the Option Plan, the Company granted to Mr. Keller an option
exercisable for a number of shares of common stock equal to 50.0% of the shares
in the Option Pool (as defined herein). Mr. Keller's employment agreement
further provides that if the Company increases the number of shares in the
Option Pool, the Company will promptly grant to Mr. Keller an option exercisable
for a number of shares of common stock equal to 50.0% of the amount such
increase. See "--1997 Stock Option Plan" for a discussion of the extent to which
the number of shares of common stock in the Options Pool will increase
automatically. In connection with the acquisition of Antelope, Mr. Keller
received an option to purchase approximately 91,400 shares of common stock. Upon
the completion of the offering, the Option Pool will increase by approximately
131,600 shares of common stock, and Mr. Keller will receive an additional option
to purchase an aggregate of approximately 65,800 shares of common stock.
 
                                       80
<PAGE>
    Mr. Keller's employment agreement also specifies that the exercise price,
vesting schedule and other terms of any stock option granted to him under the
Option Plan will be substantially similar to the terms of any other
contemporaneously granted stock option under the Option Plan, except that any
stock option granted to Mr. Keller will (a) not have an exercise price less than
the fair market value of the common stock at the time of grant; (b) to the
extent the stock option has an escalating exercise price or a fixed exercise
price with a premium over the then fair market value of the common stock,
reflect an annual percentage increase of not greater than the then current yield
to maturity of the most recently auctioned 5-year U.S. Treasury Notes; (c) vest
over a period of not more than four years from the date of grant; (d) provide
that if Mr. Keller's employment is terminated by the Company other than for
cause (as defined Mr. Keller's employment agreement), the stock option will
continue to be exercisable until such date as it would have expired if Mr.
Keller had continued to be employed by the Company; and (e) provide that upon a
Change in Control of the Company (as defined in Mr. Keller's employment
agreement), any stock option then outstanding will become fully exercisable. See
"-- 1997 Stock Option Plan" for a discussion of the exercise price and vesting
schedule structure of Mr. Keller's options.
 
    SUPPLEMENTAL RETIREMENT PROGRAM.  Mr. Keller's employment agreement
obligates the Company to provide supplemental retirement benefits through a
nonqualified, unfunded arrangement equal up to 35% of Mr. Keller's average base
salary after seven years of service. The supplemental retirement benefit accrues
and vests annually at the rate of 5% per year. The supplemental retirement
benefit will be paid monthly for ten years commencing upon (a) the later of Mr.
Keller's retirement date or age 65 or (b) Mr. Keller's death, whichever occurs
first. Any retirement benefits remaining unpaid at Mr. Keller's death will be
paid to his designated beneficiary.
 
    BENEFITS UPON TERMINATION.  Mr. Keller's employment agreement provides that
if his employment is terminated by the Company without cause or by him due to a
material change in the nature or scope of his responsibilities or duties, or a
material breach by the Company of the employment agreement, the Company
generally will be obligated to pay Mr. Keller his Base Salary for the remainder
of the term of his employment agreement or 18 months, whichever is greater.
During such period, the Company also would be obligated to continue certain
employee benefits, such as life, health, accident and disability insurance
coverage, which Mr. Keller was receiving immediately preceding his termination.
In addition, upon the events described above, Mr. Keller's supplemental
retirement benefits would become fully vested, and all options granted to Mr.
Keller to purchase common stock will become fully vested and exercisable.
 
    If Mr. Keller's employment is terminated by the Company because Mr. Keller
becomes disabled (as defined in the employment agreement), Mr. Keller will be
entitled to receive not less than 50% of his then Base Salary until age 65. In
addition, all of his options to purchase common stock will immediately become
fully vested and exercisable.
 
    If Mr. Keller's employment agreement expires following a notice of
non-renewal given by the Company, Mr. Keller would be entitled to the
continuance for a period of six months of his Base Salary and the employee
benefits that Mr. Keller was receiving immediately prior to such termination.
 
    Payments to which Mr. Keller would be entitled upon termination will be
reduced by amounts earned by Mr. Keller for services provided to another party
after such termination. Mr. Keller would have no duty, however, to mitigate such
payments by seeking to provide services to another party. Mr. Keller's
employment agreement also provides that under certain circumstances involving a
change in control, the amount of benefits provided under his employment
agreement would be reduced if, after applying the excise tax provisions to the
payments under the Internal Revenue Code of 1986, as amended, the net economic
benefit to Mr. Keller would be increased by effecting such a reduction.
 
    Mr. Keller's employment agreement provides that a "change in control" will
include the authorization of certain business combinations by the Company's
Board of Directors. In general, a business combination involving the Company
will not be deemed to be a change in control if the Company's shareholders own
at least one-third of the resulting entity and at least half of the directors of
the resulting entity are persons
 
                                       81
<PAGE>
who were directors of the Company at the time the parties entered into the
definitive agreement providing for the business combination.
 
OTHER EXECUTIVE EMPLOYMENT AGREEMENTS
 
    The Company also has entered into employment agreements with Catherine C.
Clampitt, Executive Vice President, Richard Korsgaard, Executive Vice President
and William D. Rast, Executive Vice President.
 
    Ms. Clampitt is employed by Eldorado Bank as Executive Vice President
pursuant to a one year employment agreement, renewable annually (the "Clampitt
Agreement"), entered into in July 1997. The Clampitt Agreement establishes a
monthly base salary of approximately $5,000 per month, plus commissions based
upon the volume of SBA 7(a) loan originations and fees generated by the sale of
portions of SBA 504 loans. See "Business -- Products and Services." In the event
Ms. Clampitt either is terminated by Eldorado Bank without cause or terminates
the Clampitt Agreement for good reason (as defined in the Clampitt Agreement)
following a change in control of the Company or Eldorado Bank, she will be
entitled to receive a termination payment in an amount equal to 12 months pay,
inclusive of commissions, for the prior 12 months of her employment. The
Clampitt Agreement may not be terminated by an acquisition or dissolution of
Eldorado Bank or the Company except in the event that proceedings for the
liquidation of the Company or Eldorado Bank are commenced by regulatory
authorities, in which case the Clampitt Agreement, and all rights and benefits
thereunder, would be terminated.
 
    Mr. Korsgaard is employed by Eldorado Bank as Executive Vice President
pursuant to a three-year employment agreement that expires October 19, 2001 (the
"Korsgaard Agreement") and that will be renewed automatically for successive
one-year periods unless either Eldorado Bank or Mr. Korsgaard gives the other
notice at least one year prior to the end of the term or any extension thereof.
The Korsgaard Agreement establishes a minimum base salary of $132,200. In the
event Mr. Korsgaard is terminated by Eldorado Bank or any successor to Eldorado
Bank without cause, he is entitled to receive a termination payment in an amount
equal to the greater of the balance payable under the Korsgaard Agreement or
twelve months of his then current base salary. The Korsgaard Agreement may not
be terminated by an acquisition or dissolution of Eldorado Bank or the Company
except in the event that proceedings for the liquidation of the Company or
Eldorado Bank are commenced by regulatory authorities, in which case the
Korsgaard Agreement, and all rights and benefits thereunder, would be
terminated. A salary continuation program has been established for Mr.
Korsgaard, under which Mr. Korsgaard (or, in the event of his death, his heirs)
will receive $65,000 per year from Eldorado Bank for 15 years commencing upon
his reaching age 65 or his death or disability, whichever first occurs.
 
    Mr. Rast's employment agreement with Eldorado Bank provides for an annual
salary of $175,000 and bonus payments if the Mortgage Banking Division's income
is greater than $2.0 million. The bonus payment will be $50,000 if the
Division's net income is greater than $2.0 million but not greater than $3.0
million, and the bonus will increase by $50,000 for each $1 million by which the
Division's income exceeds $2.0 million up to a maximum bonus of $250,000.
 
    The Company or the Bank has entered into Severance Agreements (each a
"Severance Agreement") with Messrs. Gordon, Rast and Christianssen concerning
the ramifications of a change in control of the Company on the continued
employment of each such officer. As used in the Severance Agreement, the term
"change in control" has the same definition as in the Option Plan. Pursuant to
and as detailed further in each Severance Agreement, if the terms of an
officer's employment are significantly altered to the detriment of that officer
within two years following a change in control, and the officer provides the
requisite notice to Eldorado Bank or alternatively, if Eldorado Bank terminates
the officer without cause within two years following a change in control, then
the officer is entitled to a lump sum payment equal to one year's salary, less
applicable taxes and withholdings. A precondition to such payment is the
execution by the officer of a general release and confidentiality agreement.
 
                                       82
<PAGE>
1997 STOCK OPTION PLAN
 
    GENERAL.  Pursuant to the Option Plan, the Company's Board of Directors or
the Compensation Committee (the "Committee") may grant stock options to Mr.
Keller and other officers of the Company or any of its subsidiaries, as well as
to any director of any subidiary. The Option Plan provides only for the issuance
of so-called "nonqualified" stock options (as compared to incentive stock
options). Upon completion of the offering, approximately 1,043,000 shares of
common stock will be reserved for issuance under the Option Plan, of which
options to purchase approximately 693,490 shares will be outstanding with an
average exercise price of approximately $10.72 per share.
 
    OPTION POOL.  The maximum number of shares as to which options may be
granted is referred to as the "Option Pool." Upon completion of the offering,
the Option Pool will consist of approximately 1,043,000 shares of common stock.
Until such time as the Company has Tier 1 Capital of $125.0 million or more, if
the Company issues any additional common stock or common stock equivalents, the
number of shares in the Option Pool automatically increases such that the number
of shares in the Option Pool will be equal to 6% of the sum of (i) the shares of
common stock (and common stock equivalents) issued and outstanding immediately
following such issuance and (ii) the number of shares in the Option Pool. On a
pro forma basis giving effect to the offering, the Company had Tier 1 Capital of
$85.3 million at December 31, 1998.
 
    EXERCISE PRICE STRUCTURE.  The Option Plan authorizes the Committee to set
the exercise price for each option grant. In the case of option grants to Mr.
Keller, each portion of his award will have a separate, fixed exercise price as
such portion vests over time. The exercise price for each separate tranche will
increase progressively based upon a semi-annual compounding of a "base rate"
using the five-year U. S. Treasury rate in effect at the date of grant. See, for
example, "-- Option Grants in Last Fiscal Year."
 
    VESTING SCHEDULE AND DURATION.  The options granted to date, and any future
grants, unless the Committee otherwise decides, will vest over four years, in
half-year increments, with the first portion vesting on the 18-month anniversary
of the date of grant. The Option Plan provides that unless the Committee
otherwise determines, the options will have a six-year term, expiring on the
sixth anniversary of the date of grant.
 
    ACCELERATION EVENT--EFFECT ON VESTING.
 
    MR. KELLER.  Mr. Keller's options will become fully vested in connection
with a change in control, which is defined in the Option Plan consistent with
the definition of a change in control contained in Mr. Keller's employment
agreement. In addition, Mr. Keller's options become fully-vested if the Company
terminates his employment agreement without cause or if he terminates the
agreement for cause. Mr. Keller's options also become fully-vested if he dies or
becomes permanently disabled.
 
    OTHER OPTION HOLDERS.  For all other option holders, the Option Plan
provides for a "double trigger," unless the Committee otherwise specifies at the
time it awards the option. Under the double trigger approach, the option would
become fully vested if the option holder is actually or constructively
terminated without cause during a two-year period following a change in control.

(1) The potential realizable value of options granted to the named executive
    officers is based upon the market value of the common stock on the date of
    grant as determined by the Compensation Committee of the Company's Board of
    Directors on the various dates of grant.
 
(2) Absent a change in control of the Company, as defined in the Option Plan,
    each tranche of option shares will vest over four years, in half-year
    increments, with the first portion vesting on the 18-month anniversary of
    the date of grant. Upon a change in control, the exercisability of the
    option is accelerated to such date. Following a change in control, the
    exercise price with respect to any option shares exercised prior to their
    original vesting date shall equal the exercise price for those option shares
    that had a scheduled vesting date that was on or next preceding such
    exercise date.
 
OTHER BENEFIT PLANS
 
    The Company's executive officers are also entitled to short-term disability,
life, medical and dental insurance and to participate in the Company's 401(k)
retirement plan.

                              CERTAIN TRANSACTIONS
 
TRANSACTIONS WITH CERTAIN SHAREHOLDERS
 
    DIRECT SALE OF SHARES IN THE OFFERING.  Concurrently with the sale and
purchase of the shares of common stock under the Purchase Agreement among the
Company, the selling shareholders and Keefe, Bruyette & Woods, Inc., as
representative, on behalf of the underwriters, the Company has agreed to sell
and some of the Company's principal shareholders and directors named in this
prospectus have agreed to purchase a total of 350,000 shares of common stock at
a price of $9.30 per share. The sale of those shares is not being underwritten
by the underwriters, and the Company is not paying any underwriting discounts or
commissions in respect of those shares.
 
    LOAN FROM DCG TO THE COMPANY.  On March 27, 1998, DCG loaned to the Company
$540,000, substantially all of which was used by the Company for the redemption
on that date of certain subordinated debentures originally issued by the
Company's predecessor, SDN. The promissory note evidencing the loan (the "DCG
Note") is repayable in eight quarterly installments commencing June 30, 1998 and
bears interest at a fixed rate of 10.5%, which was equal to Eldorado Bank's
prime rate plus 2.0% at the time of the DCG Note. The DCG Note is prepayable at
any time without penalty. The Company intends to repay the DCG Note in full,
using proceeds of the offering, contemporaneously with the closing of the
offering.
 
    REDEMPTION OF SERIES B PREFERRED STOCK.  On June 6, 1997, as part of the
financing for the acquisition of Eldorado Bancorp, the Company issued shares of
11% Series B Preferred Stock, $100 liquidation value per share (the "Series B
Preferred Stock"), having an aggregate liquidation amount of $11,659,300. All of
the outstanding Series B Preferred Stock is currently held by two of the
Company's principal sharehholders (Madison Dearborn and Olympus) in
substantially equal proportions. See "Principal and Selling Shareholders."
 
    The Series B Preferred Stock is redeemable pursuant to its terms at the
Company's option, at a redemption price of 103% of its liquidation amount, plus
accrued and unpaid dividends, or a total of $12,009,079 plus accrued and unpaid
dividends. Using proceeds of the offering, the Company intends to redeem all of
the outstanding Series B Preferred Stock contemporaneously with the closing of
the offering. The redemption of the Series B Preferred Stock is subject to the
prior approval of the Federal Reserve. The Company received the approval of the
Federal Reserve for such redemption on March 24, 1999.
 
    CONVERSION OF SPECIAL COMMON STOCK.  Most of the common stock held by
Madison Dearborn and Olympus prior to the offering is designated as "Special
Common Stock" under the Company's Certificate of Incorporation and is currently
entitled to a liquidation preference of $9.62 per share over the other common
stock. See "Descriptions of Capital Stock." Madison Dearborn and Olympus have
agreed with the Company to convert all of their Special Common Stock into common
stock prior to the closing of the offering.
 
    AMENDMENT OF SHAREHOLDER AGREEMENT.  The Company is a party to a Shareholder
Agreement, dated June 6, 1997 (the "Shareholder Agreement"), among itself,
Madison Dearborn, Olympus, DCG and certain shareholders of the DCG General
Partner. The Shareholder Agreement creates various rights in favor of, and
obligations on, its parties with respect to their direct and indirect
investments in the Company.
 
    Immediately prior to completion of the offering, the parties to the
Shareholder Agreement intend to amend the Shareholder Agreement, eliminating
most of its operative provisions. The material provisions that will remain in
effect will provide as follows: (i) unless and until both Madison Dearborn and
Olympus hold 9.9% or less of the common stock (treating any common stock
equivalents that they hold as fully exercised), DCG may not transfer any common
stock or distribute any common stock to DCG's partners if,
 
                                       90
<PAGE>
as a result of that transfer or distribution, DCG would hold fewer shares of
common stock than either Madison Dearborn or Olympus; (ii) neither Madison
Dearborn nor Olympus will transfer any of its common stock (or warrants
exercisable for common stock) without the prior approval of the Federal Reserve
unless certain exceptions apply (which generally are intended to ensure that the
transferee is not acquiring a substantial ownership interest in the Company
without the approval of the Federal Reserve); and (iii) DCG will not sell any of
its shares of common stock during a limited period before or after certain
registered offerings of the shares of common stock held by Madison Dearborn and
Olympus. See "Description of Capital Stock -- Registration Rights."
 
    NOMINATION OF DIRECTORS UNDER SECURITIES AGREEMENT.  Pursuant to the
agreement providing for the Madison Dearborn and Olympus investments in
connection with the acquisition of Eldorado Bancorp, the Company generally is
obligated to nominate designees of Madison Dearborn and Olympus for election to
the Company's Board of Directors. Nominees of each of Madison Dearborn (Paul R.
Wood) and Olympus (James A Conroy) have been nominated and elected, and
currently serve on the Company's Board of Directors. See "Management" and
"Principal and Selling Shareholders." The Company's obligation will terminate
when the amount of Company securities held by the applicable shareholder falls
below certain pre-designated levels.
 
    FUNDING FOR ELDORADO ACQUISITION.  Approximately $94.8 million of cash was
necessary to pay the cash consideration to holders of Eldorado Bancorp common
stock and stock options and acquisition-related expenses incurred by the
Company.
 
    In conjunction with the financing of the acquisition of Eldorado Bancorp,
certain directors of the Company and other investors in DCG agreed to purchase
up to approximately $14.9 million of common stock at a price of $9.62 per share,
less a 1% commitment fee, to fund a portion of the acquisition. Approximately
$8.5 million of this commitment was invested by such investors with 886,558
shares of common stock issued to them at the $9.62 per share price (less a 1%
commitment fee). Of those shares, the following numbers of shares were purchased
by persons who were then directors of the Company, nominees to become directors
of the Company, or affiliates of the Company: (i) Ernest J. Boch (550,914
shares), Edward A. Fox (25,048 shares), Charles E. Hugel (8,713 shares), Robert
P. Keller (5,957 shares), K. Thomas Kemp (5,730 shares), each of whom was a
director of the Company in December 1996; (ii) Byrne & sons, l.p. (55,897
shares); (iii) Northwood Ventures LLC and Northwood Capital Partners LLC (a
total of 17,820 shares); and (iv) Mitchell A. Johnson (45,841 shares). John B.
Pettway and Henry T. Wilson are directors of the Company and in December 1996
were directors of the DCG General Partner. Mr. Pettway is the Chief Financial
Officer of Byrne & sons, l.p., and Mr. Wilson is a Managing Director of
Northwood Ventures LLC and Northwood Capital Partners LLC. Mr. Johnson became a
director of the Company in 1997 contemporaneously with the closing of the
acquisition. See "Principal and Selling Shareholders."
 
    DCG purchased 506,122 of those shares of common stock for aggregate
consideration, net of a 1% commitment fee, of $4,419,793, of which $4.3 million
initially was made in the form of a loan to the Company in December 1996 to fund
an escrow account that would have been forfeited to Eldorado Bancorp if the
Company were unable to consummate its acquisition financing. Peter H. Paulsen,
then a director of the Company, loaned $200,000 to the Company on the same terms
as DCG. That $4.5 million was converted to shares of common stock upon the
consummation of the acquisition at a purchase price of $8.80 per share less the
1% commitment fee, and the interest on such loan (included in the purchase price
stated above) was converted to common stock at a purchase price of $9.62 per
share less the 1% commitment fee, which was the same price at which the
remaining shares of common stock and the Special Common Stock were sold by the
Company to fund the acquisition.
 
    The Company also sold a total of 2,412,859 shares of Special Common Stock to
DCG, Madison Dearborn and Olympus at a gross purchase price of $9.62 per share,
representing an aggregate payment, net of a 1% commitment fee, of $22,984,570.
Neither Madison Dearborn nor Olympus is an affiliate of the
 
                                       91
<PAGE>
other, and prior to their investment in the Company, neither was an affiliate of
the Company or DCG. The Special Common Stock acquired by DCG, Madison Dearborn
and Olympus had a liquidation preference if, in the case of a liquidation or a
change in control of the Company, the distribution per share of common stock is
less than $9.62. DCG subsequently transferred its shares of Special Common Stock
to Madison Dearborn and Olympus. The Special Common Stock will be converted to
common stock, and the foregoing liquidation preference will be eliminated prior
to the closing of the offering.
 
    CSBI Capital Trust I (the "Trust"), a special purpose trust formed by the
Company, issued a total of 27,657 of its 11 3/4% Subordinated Capital Income
Securities, Series A, $1,000 initial liquidation amount per security (the
"Capital Securities"), to DCG, Madison Dearborn and Olympus for an aggregate
cash payment, net of a 1% commitment fee, of $27,386,368. The Trust in turn
invested the proceeds of the Capital Securities in a Subordinated Debenture
issued by the Company. DCG, Madison Dearborn and Olympus all subsequently sold
their Capital Securities to a group of unrelated third parties.
 
    The Company issued a total of 116,593 shares of Series B Preferred Stock to
DCG, Madison Dearborn and Olympus for an aggregate amount of $11,545,210, net of
a 1% commitment fee. DCG subsequently sold all of its shares of Series B
Preferred Stock to Madison Dearborn and Olympus.
 
    In connection with the purchase of the Series B Preferred Stock, each of
Madison Dearborn, Olympus and DCG purchased a common stock warrant
(collectively, the "Investor Warrants") that entitles the holder to purchase
shares of common stock at an exercise price of $9.62 per share. An aggregate of
2,000,000 shares of common stock are subject to the Investor Warrants; however,
the Investor Warrants must be exercised on a cashless basis. As a result,
assuming a fair market value for the common stock equal to $10.00 per share on
the date of exercise, the Investor Warrants would be exercisable for an
aggregate of approximately 76,000 shares. The Investor Warrants expire on June
6, 2007. The aggregate purchase price of the Investor Warrants was $40,000. DCG
subsequently sold its Investor Warrants to Madison Dearborn and Olympus.
 
    FUNDING FOR CSB ACQUISITION.  As of August 28, 1996, DCG invested
approximately $14.5 million in SDN to fund the Company's acquisition of CSB. In
exchange for that investment, SDN issued 1,832,388 shares of common stock at a
price per share of $7.90.
 
    FUNDING FOR LIBERTY ACQUISITION.  As of March 27, 1996, DCG invested
approximately $13.4 million in SDN to fund SDN's acquisition of Liberty. In
exchange, SDN issued 1,696,202 shares of common stock at a price of $7.90 per
share. In addition, SDN issued a total of 19,850 shares of common stock to
accredited investors contemporaneously with the Liberty acquisition in exchange
for cash or services at a price of $10.37 per share.
 
OTHER MATTERS
 
    Some of the executive officers of the Banks and their immediate families, as
well as the companies with which such directors and executive officers are
associated, are customers of, and have had banking transactions with one or both
of the Banks in the ordinary course of the Banks' business, and the Banks expect
to have such ordinary banking transactions with such persons in the future. In
the Company's opinion, all loans and commitments to lend included in such
transactions were made in compliance with applicable laws on substantially the
same terms, including interest rates and collateral, as those prevailing for
comparable transactions with other persons of similar creditworthiness and did
not involve more than a normal risk of collectibility or present other
unfavorable features. Although the Banks do not have any limits on the aggregate
amount it would be willing to lend to directors and officers as a group, loans
to individual directors and officers must comply with the Bank's lending
policies and statutory lending limits. There were no loans to executive officers
or directors of the Company at December 31, 1998.

                          DESCRIPTION OF CAPITAL STOCK
 
    The following summary of the terms of the common stock and the Preferred
Stock of the Company does not purport to be complete and is subject to, and is
qualified in its entirety by, the provisions of the Company's Certificate of
Incorporation.
 
COMMON STOCK
 
    GENERAL.  As of the closing of the offering, the common stock of the Company
will consist of two classes, each having a par value of $.01 per share: voting
common stock and non-voting common stock. Upon completion of the offering, there
will be 35,000,000 shares of voting common stock authorized and 14,099,001
shares outstanding and 5,000,000 shares of non-voting common stock authorized
and no shares outstanding. All of the shares being offered pursuant to this
prospectus are shares of voting common stock. With the exception of voting
rights, the powers, preferences and rights of each of the classes of common
stock are identical, as summarized below.
 
    DIVIDENDS.  Except as limited by any series of Preferred Stock that may
hereafter be issued, the Company may pay dividends on the voting common stock
and the non-voting common stock as declared from time to time by its Board of
Directors out of funds legally available therefor. With certain exceptions, a
Delaware corporation (such as the Company) may pay dividends only out of (i) its
surplus (as defined under the Delaware General Corporation Law ("DGCL")), or
(ii) if there is no surplus, out of net profits for the fiscal year in which the
dividend is declared and/or the preceding year. The Company's principal source
of cash flow for the payment of dividends will be dividends from the Banks,
which are subject to substantial regulatory restrictions on the payment of
dividends. See "Risk Factors -- No present intention to pay dividends;
Restrictions on payment of dividends by the Banks to Eldorado; Prohibition on
dividends by Eldorado Bank to Eldorado without prior regulatory approval" and
"Supervision and Regulation."
 
    VOTING RIGHTS.  Except as may be provided with respect to any series of
Preferred Stock that may be issued after the date of this prospectus, the
holders of the voting common stock possess exclusive voting rights. The
non-voting common stock is not entitled to vote in any matter, excepting only
amendments to the Company's Certificate of Incorporation adversely affecting the
rights of the non-voting common stock. Each holder of voting common stock is
entitled to one vote for each share held on all matters voted upon by
shareholders. Shareholders are not permitted to cumulate votes in elections of
directors. Action by the holders of voting common stock may be taken by written
consent only if the matter to be voted upon has been approved by the Board of
Directors.
 
    LIQUIDATION.  Subject to any prior rights that may be granted to the holders
of any shares of Preferred Stock that may be outstanding as of the applicable
time, in the event of any liquidation, dissolution or winding up of the Company,
the holders of the common stock would be entitled to receive, after payment of
all debts and liabilities of the Company, all assets of the Company that are
available for distribution. See "-- Effect of Capital Securities on Common
Stock."
 
    CONVERSION.  Non-voting common stock is convertible at any time at the
election of the holder into voting common stock, except that at no time may a
holder of non-voting common stock convert such shares into voting common stock
if such conversion of shares would result in such holder beneficially owning
more that 9.9% of the voting common stock then outstanding.
 
    PROPOSED RECLASSIFICATION.  As reflected in the Company's Supplemental
Consolidated Financial Statements and Consolidated Financial Statements, as of
December 31, 1998, the common stock was divided into several classes consisting
of (i) Special Common Stock, having a liquidation preference of $9.62 per share,
a portion of which consisted of Voting Special Common Stock and a portion of
which consisted of Non-voting Special Common Stock, (ii) voting common stock
(designated as "Class B Common Stock"), and (iii) non-voting common stock
(designated as "Class C Common Stock"). Madison Dearborn and Olympus, as the
holders of the Special Common Stock, and the Company have agreed that
immediately prior to the completion of the offering, the Special Common Stock
will be converted into
 
                                       93
<PAGE>
Class B Common Stock, and the common stock will then be consolidated into two
classes, consisting of the voting common stock offered hereby and non-voting
common stock. See "Certain Transactions" and "Capitalization."
 
PREFERRED STOCK
 
    SERIES B PREFERRED STOCK.  The Company currently has 116,593 shares of
Series B Preferred Stock outstanding, which are held by two of the Company's
principal shareholders. See "Principal and Selling Shareholders." The Company
has agreed to redeem the Series B Preferred Stock upon completion of the
offering. See "Use of Proceeds."
 
    OTHER SERIES OF PREFERRED STOCK.  Upon completion of the offering, there
will be 1,500,000 shares of Preferred Stock authorized, of which no shares will
be outstanding. The Company's Board of Directors has the authority to determine
the powers, rights and preferences of any other series of Preferred Stock issued
by the Company without the approval of the holders of common stock, at the time
of the issuance, which may include, among other things, rights in liquidation,
rights to participating dividends, voting rights and rights to convert to common
stock.
 
    The rights, preferences, privileges, and restrictions or qualifications of
different series of Preferred Stock may differ with respect to dividend rates,
amounts payable on liquidation, voting rights, conversion rights, redemption
provisions, sinking fund provisions, and other matters. The issuance of
Preferred Stock could decrease the amount of earnings and assets available for
distribution to holders of common stock or could adversely affect the rights and
powers, including voting rights, of holders of common stock.
 
    The existence of the Preferred Stock, and the power of the Board of
Directors to set its terms and issue a series of Preferred Stock at any time
without shareholder approval, could have certain anti-takeover effects. These
effects include that of making the Company a less attractive target for a
"hostile" takeover bid, discouraging the making of a merger proposal or
rendering it more difficult either to assume control of the Company through the
acquisition of a large block of common stock or to remove incumbent management,
even if such actions could be beneficial to the shareholders of the Company.
 
DELAWARE TAKEOVER STATUTE
 
    The Company is subject to Section 203 of the DGCL which, with certain
exceptions, prohibits a Delaware corporation from engaging in any of a broad
range of business combinations with any "interested" shareholder for a period of
three years following the date that such shareholder became an interested
shareholder, unless: (i) prior to such date, the Board of Directors of the
corporation approved either the business combination or the transaction that
resulted in the shareholder becoming an interested shareholder, (ii) upon
consummation of the transaction that resulted in the shareholder becoming an
interested shareholder, the interested shareholder owned at least 85% of the
voting stock of the corporation outstanding at the time the transaction
commenced, excluding for purposes of determining the number of shares
outstanding those shares owned (a) by persons who are directors and officers and
(b) by employee stock 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 (iii) on or after such date, the
business combination is approved by the Board of Directors and authorized at an
annual or special meeting of shareholders by the affirmative vote of at least
66 2/3% of the outstanding voting stock that is not owned by the interested
shareholder. An "interested" shareholder is defined as any person that is (a)
the owner of 15% or more of the outstanding voting stock of the corporation or
(b) an affiliate or associate of the corporation and was the owner of 15% or
more of the outstanding voting stock of the corporation at any time within the
three-year period immediately prior to the date on which it is sought to be
determined whether such person is an interested shareholder.
 
REGISTRATION RIGHTS
 
    The Company has agreed to register under the Securities Act, the resale
under certain circumstances, of shares of common stock held by DCG, Madison
Dearborn, Olympus, certain directors and other
 
                                       94
<PAGE>
shareholders. The various registration rights agreements generally obligate the
Company to effect one or more such registrations at the request of DCG, Madison
Dearborn or Olympus or to permit those shareholders and the other beneficiaries
of those agreements to include their shares, subject to certain limitations, in
one or more registrations initiated by the Company. The Company has generally
agreed to bear all fees and expenses incurred by it in connection with any
registration, as well as the fees and expenses of one counsel for the selling
shareholders. The Company has also agreed to indemnify the selling shareholders
against certain liabilities in connection with any registration of the common
stock, including liabilities under the Securities Act.
 
EFFECT OF CAPITAL SECURITIES ON COMMON STOCK
 
    GENERAL.  In connection with the acquisition of Eldorado Bancorp, CSBI
Capital Trust I, a subsidiary of the Company (the "Trust"), issued to third
parties an aggregate principal amount of $27.7 million in 11 3/4% Subordinated
Capital Income Securities, Series A (the "Capital Securities"), which represent
undivided beneficial ownership interests in the assets of the Trust. The sole
asset of the Trust is $27.7 million of 11 3/4% Junior Subordinated Debentures
(the "Subordinated Debentures") issued by the Company to the Trust. The terms of
the Subordinated Debentures and the Capital Securities are materially the same,
and payments to the Trust under the Subordinated Debentures are passed through
the Trust to the holders of the Capital Securities. In addition to its
obligations under the Subordinated Debentures, the Company has also guaranteed
certain payments on the Capital Securities to the extent the Trust has funds
available therefor.
 
    ACCOUNTING AND REGULATORY TREATMENT.  For financial reporting purposes, the
Trust is treated as a subsidiary of the Company, and accordingly, the accounts
of the Trust are included in the Supplemental Consolidated Financial Statements
and the Consolidated Financial Statements of the Company. The Capital Securities
are presented as a liability on supplemental consolidated balance sheet and the
consolidated balance sheet of the Company as a separate line item under the
caption "Subordinated Debentures" and disclosure about the Capital Securities
and the Subordinated Debentures are included in the notes to the consolidated
financial statements. For financial reporting purposes, the Company records
distributions payable on the Capital Securities as an interest expense in its
consolidated statements of income.
 
    Under current Federal Reserve regulations, the Capital Securities are
treated as Tier 1 capital of the Company for regulatory capital purposes. See
"Supervision and Regulation."
 
    LIQUIDATION PREFERENCE RELATIVE TO COMMON STOCK.  In the event of any
liquidation, dissolution or winding up of the Company, the holders of the
Capital Securities are entitled to receive payment prior to the holders of the
common stock.
 
    DISTRIBUTIONS PAYABLE ON CAPITAL SECURITIES.  Interest is payable by the
Company on the Subordinated Debentures (and, in turn, distributions are payable
by the Trust on the Capital Securities) on a quarterly basis at an annual rate
of 11 3/4%. The Company has the right to defer payment of interest on the
Subordinated Debentures for a period not to exceed 20 consecutive quarterly
periods. As a consequence of any such extension, quarterly distributions on the
Capital Securities will be deferred by the Trust for such period. During any
such deferral period, the Company may not, among other things, declare or pay
any dividend or distribution on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of the Company's capital stock,
including, without limitation, the common stock.
 
    REDEMPTION.  The Capital Securities will be redeemed upon the redemption of
the Subordinated Debentures. The Subordinated Debentures are redeemable at the
option of the Company after June 6, 2007 at a redemption premium initially equal
to 105.875% of the liquidation amount of the securities (the principal amount
plus accrued and unpaid interest) and declining over 10 years ratably to 100%
thereof. In addition, upon the occurrence of a Regulatory Capital Event (a
regulatory shift affecting the Company's ability to treat the Capital Securities
as Tier 1 Capital), a Tax Event (a regulatory shift affecting the
 
                                       95
<PAGE>
Company's ability, among other things, to deduct interest payable on the
Subordinated Debentures) or an Investment Company Event (a regulatory shift
whereby the Trust would be required to be treated as an investment company under
the Investment Company Act), the Company would be required to repurchase the
Subordinated Debentures at the greater of their principal amount or the present
value of their principal amount plus scheduled interest payments for their
remaining life and the premium payable pursuant option redemption thereof.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon completion of the offering, the Company will have 14,099,001 shares of
common stock outstanding, and 2,934,707 shares of common stock issuable upon the
exercise of outstanding warrants and options. Of the shares outstanding upon
completion of the offering, a total of approximately 4,999,000 shares, including
the shares sold pursuant to the offering, will be freely tradeable without
restriction under the Securities Act, except for any shares purchased by an
"affiliate" (as that term is defined in Rule 144) of the Company, which shares
will be subject to the resale limitations of Rule 144 of the Securities Act. The
remaining shares outstanding upon the completion of the offering may be resold
publicly only upon registration under the Securities Act or in compliance with
an exemption from the registration requirements of the Securities Act, including
the exemption provided by Rule 144 or Rule 145. In connection with the January
22, 1999 acquisition of Antelope Valley Bank, those individuals who were
directors, executive officers or principal shareholders of Antelope at the time
of the acquisition have agreed not to sell shares of common stock until the date
on which the Company publishes its results of operations for the three months
ending March 31, 1999. Those individuals received an aggregate of approximately
855,000 shares of the Company's common stock in the Antelope acquisition. In
addition, those individuals will be subject to the resale limitations of Rule
145 until January 22, 2000. Beginning June 6, 1999, an additional 673,000 shares
of common stock that were issued in connection with the June 1997 acquisition of
Eldorado Bancorp will become freely tradeable without restriction under the
Securities Act.
 
    Included in the amount of shares of common stock issuable upon the exercise
of outstanding warrants and options are 2,241,216 shares of common stock
purchasable upon the exercise of outstanding warrants, which shares upon
exercise will constitute restricted securities within the meaning of Rule 144
and will be eligible for sale in the open market subject to the applicable
requirements of Rule 144 described below. The warrants will be automatically
exercised if the market value (as defined) is greater than $24.00. In addition,
the warrants will be automatically exercised upon the later of (a) completion of
a "qualified offering" (as defined) or (b) the first business day on which the
market value equals or exceeds $19.24. As defined in the warrants, the "market
value" of the common stock will be equal to the average closing price for the
preceding 30 days on the Nasdaq National Market or, if then applicable, the
principal national securities exchange on which the common stock is traded. A
"qualified offering" is defined in the warrants as a firm-commitment
underwritten public offering pursuant to an effective registration statement
under the Securities Act covering the offer and sale of common stock to the
public at an offering price per share (prior to any underwriting discount or
commission) of at least $19.24 in which either (x) the aggregate offering price
of shares sold by the Company is not less than $25 million, or (y) the aggregate
offering price of all shares sold in the offering, including those sold by the
Company and those sold by other stockholders is not less than $30 million of
which the aggregate offering price of shares sold by the Company is not less
than $20 million. See "Certain Transactions" for a description of other
limitations on the exercise of those warrants. Two of the Company's principal
shareholders (Madison Dearborn and Olympus) are entitled to cause the Company to
register under the Securities Act the resale of up to 2,000,000 shares of common
stock purchasable upon the exercise of two of those warrants. See "Description
of Capital Stock -- Registration Rights."
 
    Upon completion of the offering, there will be 693,491 shares of common
stock issuable upon the exercise of outstanding options under the Company's
Option Plan and 349,502 additional shares of common stock reserved for future
award or grant under such plan. See "Executive Compensation -- 1997 Stock Option
Plan." The Company has filed a registration statement on Form S-8 to register
shares of common stock for issuance under the Option Plan. Common stock issued
pursuant to such registration statement upon exercise of outstanding vested
options granted pursuant to the Option Plan, other than common stock issued to
affiliates of the Company, is available for immediate resale in the open market.
 
    In general, under Rule 144, if a period of at least one year has elapsed
between the later of the date on which restricted securities were acquired from
the Company and the date on which they were acquired
 
                                       97
<PAGE>
from an affiliate, then the holder of such restricted securities (including an
affiliate) is entitled to sell that number of shares within any three-month
period that does not exceed the greater of (i) one percent of the then
outstanding shares of the common stock or (ii) the average weekly reported
volume of trading of the common stock during the four calendar weeks preceding
such sales. Sales under Rule 144 also are subject to certain requirements
pertaining to the manner of such sales, notices of such sales and the
availability of current public information concerning the Company. Any shares
not constituting restricted securities sold by affiliates must be sold in
accordance with the foregoing volume limitations and other requirements but
without regard to the one year holding period. Under Rule 144(k), if a period of
at least two years has elapsed from the later of the date on which restricted
securities were acquired from the Company and the date on which they were
acquired from an affiliate, a holder of such restricted securities who is not an
affiliate at the time of the sale and has not been an affiliate for at least
three months prior to the sale would be entitled to sell the shares immediately
and without regard to the volume limitations and other conditions described
above. As of the date of this prospectus, all of the shares of common stock that
are restricted securities under Rule 144 will have been held for more than one
year. In addition, affiliates of a company acquired by the Company are subject
for one year to the resale limitations of Rule 145, including the volume
limitations of Rule 144 described above as well as certain requirements
pertaining to the manner of sale and the availability of current public
information concerning the Company. See "Risk Factors -- Possible future sale of
shares could adversely affect prevailing market prices for our stock."
 
    The Company, its directors, executive officers and principal shareholders
have agreed that they will not offer, sell, contract to sell, pledge, grant any
option for the sale of, or otherwise dispose or cause the disposition of any
shares of common stock, or securities convertible into or exchangeable or
exercisable for such shares, for a period of 180 days after the date of this
prospectus without the prior written consent of Keefe, Bruyette & Woods, Inc.,
except for (i) in the case of the Company, the grant of options under the Option
Plan or in connection with acquisitions, and (ii) in the case of directors,
executive officers and the Principal Shareholders and certain other
shareholders, the exercise of common stock warrants and management stock options
pursuant to the Option Plan and shares of common stock disposed of as bona fide
gifts or for estate planning purposes, subject in each case to any remaining
portion of the 180-day period applying to shares so issued or transferred. In
evaluating any request for a waiver of the 180-day lock-up period, Keefe,
Bruyette & Woods, Inc. will consider, in accordance with their customary
practice, all relevant facts and circumstances at the time of the request,
including, without limitation, the recent trading market for the common stock,
the size of the request and, with respect to a request by the Company to issue
additional equity securities, the purpose of such an issuance. Such lock-up
arrangement will not apply to shares acquired by any director or principal
shareholder directly from the Company pursuant to the offering, which instead
will be subject to only those restrictions, if any, necessary to comply with
NASD regulations. In addition, there is no restriction on the ability of DCG to
distribute shares of common stock to its general and limited partners; however,
any such shares will be subject to any lock-up agreement executed by such
general or limited partner.
 
    Sales of substantial amounts of common stock by existing shareholders could
have an adverse effect on the prevailing market price of the common stock. No
predictions can be made as to the effect, if any, that market sales of shares by
existing shareholders or the availability of such shares for future sales will
have on the market price of shares of common stock prevailing from time to time.

</TABLE>
 
    Concurrently with the sale and purchase of the shares under the Purchase
Agreement, the Company has agreed to sell, and some of the Company's principal
shareholders and directors named in this prospectus have agreed to purchase, a
total of 350,000 shares of common stock at a price of $9.30 per share. The sale
of those shares is not being underwritten by the underwriters, and the Company
is not paying any underwriting discounts and commissions in respect of those
shares.
 
    The Purchase Agreement provides that the obligations of the underwriters are
subject to certain conditions precedent, including the simultaneous closing of
the sale of shares of common stock to certain of the Company's principal
shareholders and directors, and that the underwriters will purchase all such
shares of the common stock if any of such shares are purchased. The underwriters
are obligated to take and pay for all of the shares of common stock offered
hereby (other than those covered by the over-allotment option described below
and those to be purchased by certain principal shareholders and directors of the
Company) if any are taken.
 
    The Company has been advised by the Representative of the underwriters that
the underwriters propose to offer the shares of common stock purchased from the
Company to the public at the public offering price set forth on the cover page
of this prospectus and to certain dealers at such price less a concession not in
excess of $.42 per share. The underwriters may allow, and such dealers may
re-allow, a concession not in excess of $.10 per share to certain other dealers.
After the initial public offering, the offering price and other selling terms
may be changed by the Representative of the underwriters.
 
    Pursuant to the Purchase Agreement, the Company has granted to the
underwriters an option, exercisable not later than 30 days after the date of
this prospectus, to purchase up to 286,400 additional shares of common stock at
the public offering price, less the underwriting discounts and commissions set
forth on the cover page of this prospectus, solely to cover over-allotments. To
the extent that the underwriters exercise such option, each underwriter will
become obligated, subject to certain conditions, to purchase approximately the
same percentage of such additional shares as the number set forth next to such
underwriter's name in the preceding table bears to the total number of shares in
such table, and the Company will be obligated, pursuant to the option, to sell
such shares to the underwriters.
 
    The Company and each of its directors, executive officers and principal
shareholders have agreed with the Representative not to sell or otherwise
dispose of any shares of common stock, or any securities convertible into or
exercisable or exchangeable for shares of common stock, for a period of 180 days
after the date of this prospectus without the prior written consent of the
Representative, except for: (i) in the case of the Company, the grant of options
or restricted stock under management compensation arrangements or in connection
with acquisitions and (ii) in the case of such holders, the exercise of common
stock
 
                                       99

warrants and management stock options pursuant to the Option Plan and shares of
common stock disposed of as bona fide gifts or for estate planning purposes,
subject, in each case, to any remaining portion of the 180-day period applying
to any shares so issued or transferred. Such lock-up arrangement will not apply
to shares acquired by any director or principal shareholder directly from the
Company pursuant to the offering, which instead will be subject to only those
restrictions, if any, necessary to comply with NASD regulations. In addition,
there is no restriction on the ability of DCG to distribute shares of common
stock to its general and limited partners; however, any such shares will be
subject to any lock-up agreement executed by such general or limited partner.
 
    The Representative has advised the Company that the underwriters do not
intend to confirm sales to any account over which they exercise discretionary
authority.
 
    The Company and the selling shareholders have agreed to indemnify the
underwriters against certain liabilities, including liabilities under the
Securities Act.
 
    Until the distribution of the common stock is completed, rules of the SEC
may limit the ability of the underwriters and certain selling group members to
bid for and purchase the common stock. As an exception to these rules, the
underwriters are permitted to engage in certain transactions that stabilize the
price of the common stock. Such transactions consist of bids or purchases for
the purpose of pegging, fixing or maintaining the price of the common stock.
 
    If the underwriters create a short position in the common stock in
connection with the offering, i.e., if they sell a greater aggregate number of
shares of common stock than is set forth on the cover page of this prospectus,
the underwriters may reduce the short position by purchasing shares of common
stock in the open market. The underwriters may also elect to reduce any short
position by exercising all or part of the over-allotment option described above.
 
    The underwriters may also impose a penalty bid on certain selling group
members. This means that if the underwriters purchase common stock in the open
market to reduce the selling group members' short position or to stabilize the
price of the common stock, they may reclaim the amount of the selling concession
from the selling group members who sold those shares of common stock as part of
the offering.
 
    In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of a security to the extent that it were
to discourage resales of the security.
 
    Neither the Company nor the Representative makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the common stock. In addition, neither
the Company nor the Representative makes any representation that the
underwriters will engage in such transactions or that such transactions, once
commenced, will not be discontinued without notice.
 
    The underwriters and dealers may engage in passive market making
transactions in the shares of common stock in accordance with Rule 103 of
Regulation M promulgated by the SEC. In general, a passive market maker may not
bid for, or purchase, shares of common stock at a price that exceeds the highest
independent bid. In addition, the net daily purchases made by any passive market
maker generally may not exceed 30% of its average daily trading volume in the
common stock during a specified two month prior period, or 200 shares, whichever
is greater. A passive market maker must identify passive market making bids as
such on the Nasdaq electronic inter-dealer reporting system. Passive market
making may stabilize or maintain the market price of the common stock above
independent market levels. Underwriters and dealers are not required to engage
in passive market making and may end passive market making activities at any
time.

    Trading in the common stock has been extremely limited prior to the offering
and cannot be characterized as amounting to an established public trading
market. Eldorado has been quoted on the Nasdaq National Market since February 1,
1999 under the symbol "ELBI." Prior to the offering, there has been no public
market for the common stock. Consequently, the public offering price for the
common stock will be determined by negotiations between the Company and the
Representative of the underwriters. Among the factors to be considered in
determining the public offering price of the common stock will be the prevailing
market for the common stock and general economic conditions, the market
capitalizations, trading histories and stages of development of other traded
companies that the Company and the Representative believe to be comparable to
the Company, the results of operations of the Company in recent periods, the
current financial position of the Company, estimates of the business potential
of the Company and the present state of the Company's development and the
availability for sale in the market of a significant number of shares of common
stock. Additionally, consideration will be given to the general status of the
securities market, the market conditions for new issues of securities and the
demand for securities of comparable companies at the time the offering is made.
 
                                 LEGAL MATTERS
 
    Certain legal matters, including the validity of the common stock, have been
passed upon for the Company by Nutter, McClennen & Fish, LLP, Boston,
Massachusetts, and for the underwriters by Skadden, Arps, Slate, Meagher & Flom
LLP, New York, New York. Michael K. Krebs, the Secretary of the Company, is a
partner of Nutter, McClennen & Fish, LLP.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholders of
Eldorado Bancshares, Inc.
 
We have audited the accompanying supplemental consolidated statement of
condition of Eldorado Bancshares, Inc. (formerly Commerce Security Bancorp,
Inc.) and subsidiaries (the "Company") as of December 31, 1998 and 1997, and the
related supplemental consolidated statements of income, shareholders' equity,
and cash flows for each of the three years in the period ended December 31,
1998. These supplemental consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these supplemental consolidated financial statements based on our
audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatements. 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.
 
The supplemental consolidated financial statements give retroactive effect to
the acquisition of Antelope Valley Bank by Eldorado Bancshares, Inc., which has
been accounted for as a pooling-of-interests as described in Note 1 to the
supplemental consolidated financial statements. Generally accepted accounting
principles proscribe giving effect to a consummated business combination
accounted for by the pooling-of-interests method in financial statements that do
not include the date of consummation. These financial statements do not extend
through the date of consummation. However, they will become the historical
consolidated financial statements of Eldorado Bancshares, Inc. and subsidiaries
after financial statements covering the date of consummation of the business
combination are issued.
 
In our opinion, the supplemental consolidated financial statements referred to
above present fairly, in all material respects, the financial position of
Eldorado Bancshares, Inc. and subsidiaries as of December 31, 1998 and 1997, and
the results of their operations and their cash flows for each of the three years
in the period ended December 31, 1998, in conformity with generally accepted
accounting principles applicable after financial statements are issued for a
period which includes the date of consummation of the business combination.

            NOTES TO SUPPLEMENTAL CONSOLIDATED FINANCIAL STATEMENTS
 
                        DECEMBER 31, 1998, 1997 AND 1996
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
BASIS OF PRESENTATION
 
    Eldorado Bancshares, Inc. (formerly Commerce Security Bancorp, Inc.), a
Delaware corporation and bank holding company, and its wholly-owned subsidiaries
Eldorado Bank, Antelope Valley Bank and CSBI Capital Trust I are included in the
accompanying supplemental consolidated financial statements and are collectively
referred to as the "Company". Eldorado Bank and the Antelope Valley Bank are
collectively referred to as the "Banks." Significant intercompany transactions
and accounts have been eliminated.
 
    Prior to June 1997 and the acquisition of Eldorado Bank, the Company had
three subsidiaries, Commerce Security Bank (CSB), Liberty National Bank (LNB),
and San Dieguito National Bank (SDNB). On June 30, 1997, the Company merged the
then existing three subsidiaries into the newly acquired Eldorado Bank. On
January 22, 1999, the Company completed the acquisition of Antelope Valley Bank.
Following those transactions, the organizational structure consists of the
Company and its two wholly owned banking subsidiaries, Eldorado Bank and
Antelope Valley Bank (sometimes referred to collectively as the "Banks").
 
    The Company has accounted for the Antelope Valley Bank acquisition using the
pooling of interests method of accounting for business combinations. The
Supplemental Consolidated Financial Statements have been prepared as if the
Company had acquired Antelope Valley Bank at the beginning of the earliest
period presented.
 
BUSINESS
 
    The Banks offer a broad range of commercial banking services primarily in
Southern California and in the Sacramento area of Northern California, catering
especially to small business. The Banks offer commercial, real estate, consumer,
Small Business Administration-guaranteed loans as well as checking and savings
deposits, corporate cash management, international banking services, safe
deposit boxes, collection, traveler's checks, notary public and other customary
non-deposit banking services.
 
RISKS AND UNCERTAINTIES
 
    In the normal course of its business, the Company encounters two significant
types of risk: economic and regulatory. Economic risk is comprised of three
components--interest rate risk, credit risk and market risk. The Company is
subject to interest rate risk to the degree that its interest-bearing
liabilities mature and reprice at different speeds, or on a different basis,
than its interest-bearing assets. Credit risk is the risk of default on the
Company's loan portfolio that results from the borrower's inability or
unwillingness to make contractually required payments. Market risk results from
changes in the value of assets and liabilities which may affect, favorably or
unfavorably, the realizability of those assets and liabilities.
 
    The Company is subject to the regulations of various governmental agencies.
These regulations can and do change significantly from period to period. The
Company is also subject to periodic examinations by the regulatory agencies,
which may subject it to changes in asset valuations, in amounts of required loss
allowances and in operating restrictions resulting from the regulators'
judgments based on information available to them at the time of their
examination.

      NOTES TO SUPPLEMENTAL CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                        DECEMBER 31, 1998, 1997 AND 1996
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
RECENTLY ISSUED ACCOUNTING STANDARDS
 
    In June 1997 the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards 130, "Reporting Comprehensive
Income" (SFAS 130). This Statement provides that all enterprises report
comprehensive income as a measure of overall performance. Comprehensive income
is the change to equity (net assets) of a business during a period. The Company
implemented this standard in 1998.
 
    In June 1997 the FASB issued SFAS 131, "Disclosures About Segments of an
Enterprise and Related Information." This statement changed the way public
companies report information about segments of their business in their annual
financial statements and requires them to report selected segment information in
their quarterly reports issued to shareholders. Companies are required to
disclose segment data based upon how management makes decisions about allocating
resources to segments and measuring performance. The company implemented this
standard in 1998.
 
    In February 1998 the FASB issued SFAS 132, "Employer's Disclosures about
Pensions and other Post-Retirement Benefits." This Statement standardizes the
disclosure requirements for pensions and other post-retirement benefits to the
extent practicable. The Company implemented this standard in 1998.
 
    In June 1998 the FASB issued SFAS 133, "Accounting for Derivative
instruments and Hedging Activities." This Statement establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts, (collectively referred to as
derivatives) and for hedging activities. It requires that an entity recognize
all derivatives as either assets or as liabilities in the statement of financial
position and measure those instruments at fair value. For the Company, this new
standard is effective in 2000 and is not to be applied retroactively to
financial statements of prior periods. The impact of this Statement, if any, is
yet to be determined.
 
    In October 1998, the FASB issued SFAS 134, "Accounting for Mortgage-Backed
Securities Retained after the Securitization of Mortgage Loans Held For Sale by
a Mortgage Banking Enterprise." This Statement establishes accounting and
reporting standards for securitization of mortgage loans. For the Company, this
new standard is effective in 1999, and the impact of this Statement, if any, is
yet to be determined.
 
CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents include cash and due from banks and federal funds
sold. Generally, Federal funds sold are sold for one-day periods.
 
INVESTMENT SECURITIES
 
    The Company has classified its investment securities as held-to-maturity and
available-for-sale. No trading portfolio is maintained. Investment securities
are segregated in accordance with management's intention regarding their
retention.
 
    Investment securities classified as held-to-maturity are carried at cost,
adjusted for the amortization of premiums and the accretion of discounts.
Premiums and discounts are amortized and accreted to operations using the
straight line method, which management believes approximates the interest
method. Management has the intent and ability to hold these assets as long-term
investments until their expected

maturities. Under certain circumstances, including the significant deterioration
of the issuer's credit worthiness or a significant change in tax-exempt status
or statutory or regulatory requirements, securities classified as
held-to-maturity may be sold or transferred to another classification.
 
    Investment securities classified as available-for-sale may be held for
indefinite periods of time and may be sold to implement the Company's
asset/liability management strategies and in response to changes in interest
rates and/or prepayment risk and similar factors. These securities are recorded
at estimated fair value. Unrealized gains and losses are reported as other
comprehensive income in the supplemental consolidated statement of shareholders'
equity, net of income taxes.
 
    Gains and losses on investment securities are determined on the specific
identification method and are included in other income.

    Loans held for sale consists of mortgage loans carried at lower of cost or
fair value on an aggregate basis.
 
LOANS AND LEASES
 
    Loans are stated at principal amounts outstanding, net of unearned income,
including discounts and fees. Interest income on discounted loans, such as those
generated by the Automobile Lending Division, is recognized under a method that
approximates interest calculated using the interest method. Net deferred fees
and costs are generally deferred and amortized into interest income over the
contractual life of the related loans as a yield adjustment. Direct financing
leases, which include estimated residual values of leased equipment, are carried
net of unearned income. Income from these leases is recognized on a basis which
produces a level yield on the outstanding net investment in the lease. The
production of new leases comes exclusively from the wholesale sector through a
network of brokers. The Company services these leases and, beginning in 1997,
sells blocks of leases from time to time to other institutions. Leases held for
resale are carried at the lower of cost or estimated fair value on an aggregate
basis. Gains and losses on the sale of leases are recognized upon delivery based
on the difference between selling price and carrying value.
 
NON-ACCRUAL / IMPAIRED LOANS
 
    When payment of principal or interest on a loan is delinquent for 90 days,
or earlier in some cases, the loan is placed on nonaccrual status, unless the
loan is in the process of collection and the underlying collateral fully
supports the carrying value of the loan. When a loan is placed on nonaccrual
status, interest accrued during the period prior to the judgment of
uncollectibility is charged to operations. Generally, any payments received on
nonaccrual loans are applied first to outstanding loan amounts and next to the
recovery of charged-off loan amounts. Any excess is treated as recovery of lost
interest.
 
    SFAS 114 requires that impaired loans be measured based on the present value
of expected future cash flows discounted at the loan's effective interest rate,
the loan's observable market price, or the fair value of the collateral if the
loan is collateral dependent. When the measure of the impaired loan is less than
the recorded balance of the loan, the impairment is recorded through a valuation
allowance included in the allowance for loan and lease losses.

      NOTES TO SUPPLEMENTAL CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                        DECEMBER 31, 1998, 1997 AND 1996
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    The Company considers all loans impaired when it is probable that both
interest and principal will not be collected in accordance with the contractual
terms of the agreement. All loans that are ninety days or more past due, or have
been restructured to provide a reduction in the interest rate or a deferral of
interest or principal are automatically included in this category.
 
ALLOWANCE FOR ESTIMATED LOAN AND LEASE LOSSES
 
    A provision for estimated loan and lease losses is charged to expense when,
in the opinion of management, such losses are inherent in the portfolio. The
allowance is increased by provisions charged to expense, increased for
recoveries of loans previously charged-off, and reduced by charge-offs. Loans
and leases are charged-off when management believes that the collectibility of
the principal is unlikely. Management's estimates are used to determine the
allowance that is considered adequate to absorb losses inherent in the existing
loan and lease portfolio. These estimates are inherently subjective and their
accuracy depends on the outcome of future events. Ultimate losses may differ
from current estimates. Management's estimates are based on historical loan loss
experience, specific problem loans and leases, current economic conditions that
may impact the borrower's ability to pay, volume, growth and composition of the
loan portfolio, value of the collateral and other relevant factors.
 
MORTGAGE BANKING ACTIVITIES
 
    The Company originates and sells residential mortgage loans to a variety of
secondary market investors, including the Federal Home Loan Mortgage Corporation
(FHLMC or Freddie Mac), the Federal National Mortgage Association (FNMA or
Fannie Mae) and others. The Company has an arrangement with the Government
National Mortgage Association (GNMA or Ginnie Mae) whereby loans originated by
the Company are securitized by GNMA and sold to others. Gains and losses on the
sale of mortgage loans are recognized upon delivery based on the difference
between the selling price and the carrying value of the related mortgage loans
sold. Deferred origination fees and expenses are recognized at the time of sale
in the determination of the gain or loss. The Company sells the servicing for
such loans to either the purchaser of the loans or to a third party. The Company
recognizes the gain or loss on servicing sold when all risks and rewards of
ownership have transferred.
 
    Mortgage loans held for sale are stated at the lower of cost or market as
determined by the outstanding commitments from investors or current investor
yield requirements calculated on an aggregate loan basis. Valuation adjustments
are charged against noninterest income.
 
    Forward commitments to sell and put options on mortgage-backed securities
are used to reduce interest rate risk on a portion of loans held for sale and
anticipated loan fundings. The resulting gains and losses on forward commitments
are deferred and included in the carrying values of loans held for sale.
Premiums on put options are capitalized and amortized over the option period.
The Company expects that, in general, gains and losses on forward commitments
and put options deferred against loans held for sale will approximately offset
equivalent amounts of unrecognized gains and losses on the related loans.
Forward commitments to sell and put options on mortgage-backed securities that
hedge anticipated loan fundings are not reflected in the supplemental
consolidated statement of financial condition. Gains and losses on these
instruments are not recognized until the actual sale of the loans held for sale.
In 1996, the Company sold its portfolio of loan servicing and no longer services
mortgage loans for others.

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
SBA LENDING
 
    The Company is qualified as a "Preferred Lender" under the SBA programs,
allowing it to originate SBA loans based on its own underwriting decisions and
without prior approval of the SBA. The Company sells the government guaranteed
portion of the SBA loans at a premium, a portion of which is immediately
recognized as income. The remaining portion of the premium, representing the
estimated normal servicing fee retained by the Company, is capitalized and
recognized as income over the estimated life of the loan.
 
LOAN SERVICING RIGHTS
 
    Loan servicing rights are accounted for under the provisions of SFAS 125,
"Accounting for Transfers and Servicing of Financial Assets and Extinguishments
of Liabilities," which became effective January 1, 1997. SFAS 125 superseded
SFAS 122, "Accounting for Mortgage Servicing Rights," but did not significantly
change the methodology used to account for servicing rights. The servicing
rights currently capitalized, included in other assets, are the result of
servicing rights retained on sold SBA loans and are being amortized in
proportion to and over the period of estimated servicing income. Management
stratifies servicing rights based on origination period and interest rate and
evaluates the recoverability in relation to the impact of actual and anticipated
loan portfolio prepayment, foreclosure, and delinquency experience. The Company
did not have a valuation allowance associated with the servicing rights
portfolio as of December 31, 1998 and 1997.
 
PREMISES AND EQUIPMENT
 
    Premises and equipment are carried at cost less accumulated depreciation and
amortization. Depreciation on furniture, fixtures and equipment is computed
using the straight-line method over the estimated useful lives, which range from
two to fifteen years. Leasehold improvements are amortized using the
straight-line method over the estimated useful lives of the improvements or the
remaining lease term, whichever is shorter. Expenditures for betterments or
major repairs are capitalized and those for ordinary repairs and maintenance are
charged to operations as incurred.
 
REAL ESTATE ACQUIRED THROUGH FORECLOSURE
 
    Real estate acquired in settlement of loans is recorded at the lower of the
unpaid balance of the loan at settlement date or the fair value less estimated
costs to sell. A valuation allowance is established to reflect declines in value
subsequent to foreclosure, if any, below the new basis. Required developmental
costs associated with foreclosed property under construction are capitalized and
considered in determining the fair value of the property. Operating expenses of
such properties, net of related income, and gains and losses on their
disposition are included in other non-interest expenses.
 
INTANGIBLES ARISING FROM ACQUISITIONS
 
    The Company has paid amounts in excess of fair value for three branches of
Wells Fargo Bank and for CSB's, LNB's, and Eldorado's core deposits and tangible
assets. Such amounts are being amortized by systematic charges to income
(primarily for periods from 10 to 25 years) over a period which is no greater
than the estimated remaining life of the assets acquired or not to exceed the
estimated average remaining

life of the existing deposit base assumed. The Company periodically reviews
intangibles to assess recoverability and an impairment is recognized in
operations if a permanent loss of value occurs.
 
FEDERAL AND STATE TAXES
 
    The Company provides for income taxes under the provisions of SFAS 109,
"Accounting for Income Taxes." Under the liability method which is prescribed by
SFAS 109, a deferred tax asset and/or liability is computed for both the
expected future impact of differences between the financial statement and tax
bases of assets and liabilities, and for the expected future tax benefit to be
derived from tax loss and tax credit carryforwards. SFAS 109 also requires the
establishment of a valuation allowance, if necessary, to reflect the likelihood
of the realization of deferred tax assets. The effect of tax rate changes will
be reflected in income in the period such changes are enacted.
 
    Deferred income taxes are provided by applying the statutory tax rates in
effect at the balance sheet date to temporary differences between the book basis
and the tax basis of assets and liabilities. The resulting deferred tax assets
and liabilities are adjusted to reflect changes in tax laws or rates.
 
STOCK-BASED COMPENSATION
 
    On January 1, 1997, the Company adopted SFAS 123, "Accounting for
Stock-Based Compensation", which permits entities to recognize, as expense over
the vesting period, the fair value of all stock- based awards on the date of
grant.
 
    Alternatively, SFAS 123 also allows entities to continue to apply the
provisions of Accounting Principles Board (APB) Opinion 25 and provide pro forma
net income and pro forma earnings per share disclosures for employee stock
option grants as if the fair-value-based method defined in SFAS 123 had been
applied. The Company has elected to continue to apply the provisions of APB
Opinion 25, which requires compensation expense be recorded on the date of grant
only if the current market price of the underlying stock exceeds the exercise
price, and provide the pro forma disclosure provisions of SFAS 123. See Note 13
of the notes to supplemental consolidated financial statements for the pro forma
net income and pro forma earnings per share disclosures.

ESTIMATES
 
    The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets, liabilities and
disclosures in the consolidated financial statements. Actual results could
differ from those estimates.
 
NOTE 2--ACQUISITIONS AND 1996 REORGANIZATION:
 
    A key element of the Company's strategic plan includes building
profitability through acquisitions of community banks principally, but not
exclusively, in and around its Southern California base, including banks that
have underperformed relative to their peers but have strong lending franchises,
niche business lines or low cost deposits that would complement its existing
operations and branch network and also provide opportunities for cost savings
through branch overlap and back-office consolidation. Since September 1995, the
Company has completed four acquisitions, increasing the Company's assets by
approximately $1 billion, including the acquisition, completed on January 22,
1999, of Antelope Valley

Bank, in a transaction accounted for as a pooling of interests. In connection
with the acquisition, the Company issued approximately 2,777,000 shares of
common stock. As of December 31, 1998, Antelope had total assets of $211.7
million.
 
    On June 6, 1997, the Company acquired Eldorado Bancorp ("Eldorado") and its
bank subsidiary, Eldorado Bank, a community bank based in Tustin, California
with approximately $400 million in total assets (collectively with the financing
related thereto, the "Eldorado Acquisition"). Effective June 30, 1997, the
Company consolidated via mergers (collectively, the "Bank Mergers") into
Eldorado Bank the respective operations of its other subsidiaries--LNB, SDNB,
and CSB.
 
    On March 31, 1996, the Company's predecessor, SDN Bancorp, Inc. ("SDN"),
completed its acquisition of LNB (the "Liberty Acquisition") for approximately
$15.1 million in cash. LNB had total assets of approximately $150 million as of
the acquisition date.
 
    As of September 1, 1996, the Company completed the plan of reorganization
(the "1996 Reorganization") contemplated by the Agreement and Plan of
Reorganization dated April 23, 1996 (the "Commerce Agreement") between SDN and
CSB. As part of the 1996 Reorganization, SDN became a subsidiary of the Company,
effective August 31, 1996, in a transaction in which SDN shareholders received
shares of the Company's common stock in exchange for all of the outstanding
shares of SDN common stock. As of September 1, 1996, the Company completed the
acquisition of CSB (the "Commerce Acquisition") in which the Company acquired
all of the outstanding shares of CSB. Pursuant to the Commerce Agreement,
holders of CSB common stock received approximately $14.1 million and a total of
1,543,691 shares of Company common stock. CSB had total assets of approximately
$220 million at September 1, 1996.
 
    Effective June 6, 1997, the Company completed the Eldorado Acquisition. The
Acquisition was effected pursuant to an Agreement and Plan of Merger entered
into between the Company and Eldorado on December 24, 1996 (the "Acquisition
Agreement"). Pursuant to the Acquisition Agreement, the Company acquired 100% of
the outstanding stock of Eldorado for cash consideration of $23.00 per share.
Contemporaneously with the Acquisition, each Eldorado stock option that had not
previously been exercised (collectively, the "Eldorado Options") was canceled in
return for payment by Eldorado of the difference between the $23.00 price per
share and the exercise price thereof. The aggregate consideration paid to
holders of Eldorado common stock and Eldorado Options (net of the tax benefit
arising out of the Eldorado Options) was approximately $90.3 million. Eldorado
had total assets of approximately $400 million at June 6, 1997.
 
    The Liberty, Commerce, and Eldorado Acquisition's were accounted for using
the purchase method of accounting in accordance with APB Opinion 16, "Business
Combinations". Under this method of accounting, the purchase price was allocated
to the assets acquired and deposits and liabilities assumed based on their fair
values as of the acquisition date. The consolidated financial statements include
the operations of LNB, CSB, and Eldorado from the date of acquisition.
Intangibles arising from the transactions totaled approximately $3.8 million in
the Liberty Acquisition, $7.2 million in the Commerce Acquisition and
approximately $50.2 million in the Eldorado Acquisition. Certain preacquistion
contingency reserves were established as of the acquisition dates that are
subject to adjustment during the "allocation period" in accordance with SFAS 38
"Accounting for Preacquisition Contingencies." The fair value of CSB has been
adjusted to reflect the resolution of these contingencies established relating
to certain litigation, writedowns of real estate owned and a settlement with the
principal shareholder of CSB.

NOTE 6--MORTGAGE BANKING ACTIVITIES:
 
    The Bank originates and sells residential mortgage loans to secondary market
investors subject to certain recourse provisions. At December 31, 1998 and 1997,
the Bank had sold loans with recourse with an unpaid principal balance of
$84,194,000 and $86,568,000, respectively. The Bank had recorded a reserve of
$397,000 and $1,076,000, in connection with such sales at December 31, 1998 and
1997, respectively. During 1998 and 1997, the Bank added to this reserve $-0-
and $2,021,000, respectively, and charged off $679,000 and $1,645,000,
respectively to this account related to these repurchase obligations. In
management's opinion, these reserves are adequate to absorb losses inherent in
the outstanding recourse obligations.

NOTE 10--BORROWINGS:
 
MANDATORY CONVERTIBLE DEBENTURES
 
    Contemporaneously with the Bank Mergers on June 30, 1997, the Company
assumed certain obligations of its subsidiary SDN Bancorp. Among these
obligations were mandatory convertible debentures that totaled approximately
$537,000. The debentures were mandatorily convertible at March 30, 1998 into the
Company's common stock, at a rate equal to the lower of: (i) $52.50 per share
(subject to certain anti-dilutive adjustments and the power of the Company's
Board of Directors to reduce the conversion price), or (ii) the then current
fair market value per share of the Company's common stock. At the Company's
option, the debentures were redeemed on March 27, 1998 at 100% of par. The
Company funded the redemption of the debentures by entering into a note payable
with Dartmouth Capital Group, L.P. which matures on March 31, 2000. The note
bears interest at 10.5% annually, with principal and interest payments payable
in quarterly installments. At December 31, 1998, the outstanding principal
balance on the note was $338,000.
 
SUBORDINATED DEBENTURES
 
    In June 1997, CSBI Capital Trust I (the "subsidiary trust"), issued
$27,657,000 of 11 3/4% Trust Originated Preferred Securities (the "preferred
securities"). In connection with the subsidiary trust's issuance of the
preferred securities, the Company issued to the subsidiary trust $27,657,000
principal amount of its 11 3/4% subordinated debentures, due June 6, 2027 (the
"subordinated debentures"). The sole assets of the subsidiary trust are and will
be the subordinated debentures. The Company's obligation under the subordinated
debentures and related agreements, taken together, constitute a firm and
unconditional guarantee by the Company of the subsidiary trust's obligation
under the preferred securities.

NOTE 12--SHAREHOLDERS' EQUITY: (CONTINUED)
COMMERCE ACQUISITION
 
    Prior to August 31, 1996, the Partnership invested approximately $14.5

investment, SDN issued a total of 3,664,776 additional shares of SDN common
stock at a price per share of $3.95 pursuant to a subscription agreement entered
into in March 1996. At the Partnership's direction, SDN issued 1,080,000 of

outstanding prior to the 1996 Reorganization and the Commerce Acquisition.
Holders of CSB common stock were issued 1,527,540 shares of Company common stock

the Company's common stock and cash of approximately $346,000 are held in escrow

legislation that recapitalized the SAIF, passed on September 30, 1996, the stock
and cash escrows were distributed, with approximately $96,000 disbursed in cash
and 16,151 common shares distributed.
 
ELDORADO ACQUISITION.
 
    Approximately $94.8 million of cash was necessary to pay the cash
consideration to holders of Eldorado common stock and Eldorado stock options and
Eldorado Acquisition-related expenses incurred by the Company, of which $14.0
million was funded from Eldorado's excess capital and $80.3 million was raised
through the Company's sale, effective June 6, 1997, of Class B Common Stock,
Special Common Stock, a Junior Subordinated Debenture (and, indirectly, Series A
Capital Securities), Series B Preferred Stock and common stock warrants, as
described below.
 
    CLASS B COMMON STOCK.  In conjunction with the Eldorado Acquisition
financing, the 9,697,430 shares of Company common stock, $.01 par value per
share, outstanding immediately prior to the closing of the Eldorado Acquisition
were redesignated as "Class B Common Stock," and the Company issued 4,248,431
additional shares of Class B Common Stock to various accredited investors for
consideration, net of a 1% commitment fee, of $17,735,115.
 
    DCG, the Company's largest shareholder, purchased 1,012,244 of those shares
of Class B Common Stock for aggregate consideration, net of a 1% commitment fee,
of $4,419,793, of which $4.3 million initially was made in the form of a loan to
the Company in December 1996 to fund an escrow account that would have been
forfeited to Eldorado if the Company were unable to consummate the Acquisition
financing. Peter H. Paulsen, a director of the Company, loaned $200,000 to the
Company on the same terms as DCG. That $4.5 million was converted to shares of
Class B Common Stock upon the consummation of the Acquisition at a purchase
price of $4.40 per share less the 1% commitment fee which was the same price at
which the remaining shares of common stock and the Special Common Stock were
sold by the Company to fund the acquisition.
 
    SPECIAL COMMON STOCK.  The Company sold a total of 4,825,718 shares of
Special Common Stock, $.01 par value per share (the "Special Common"), to DCG,

purchase price of $4.81 per share, representing an aggregate payment, net of a
1% commitment fee, of $22,984,570. Neither MDP nor Olympus is an affiliate of
the other, and prior to their investment in the Company, neither was an
affiliate of the Company or DCG.
 
    The Special Common Stock will be entitled to a liquidation preference over
the Class B Common Stock if, in the case of a liquidation or a change in control
of the Company the distribution per share of Common Stock is less than $4.81.
With the exception of 927,826 shares of Non-Voting Special Common Stock issued
to each of MDP and Olympus, the Special Common Stock will have one vote per
share and will vote as a class with the Class B Common Stock. The Voting Special
Common and the Class B Common Stock are hereinafter sometimes referred to as the
"Voting Common Stock."
 
    SUBORDINATED DEBENTURE AND SERIES A CAPITAL SECURITIES.  CSBI Capital Trust
I (the "Trust"), a special purpose trust formed by the Company, issued a total
of 27,657 shares of 11 3/4% Series A Capital Securities, $1,000 initial
liquidation value per share (the "Series A Securities"), to DCG, MDP and Olympus
for an aggregate cash payment, net of a 1% commitment fee, of $27,386,368. The
Trust in turn invested the proceeds of the Series A Securities in a Junior
Subordinated Debenture issued by the Company.
 
    SERIES B PREFERRED STOCK.  The Company issued a total of 116,593 shares of
11.0% Series B Preferred Stock, $100 liquidation value per share (the "Series B
Preferred"), to DCG, MDP and Olympus for an aggregate amount of $11,545,210, net
of a 1% commitment fee.
 
    COMMON STOCK WARRANTS.  In connection with the purchase of the Series B
Preferred Stock, each of MDP, Olympus and DCG purchased a common stock warrant
(collectively, the "Investor Warrants") that entitles the holder to purchase
shares of Class B Common Stock at an exercise price of $4.81 per share. An
aggregate of 4,000,000 shares of Class B Common Stock are subject to the
Investor Warrants. The Investor Warrants expire on June 6, 2007. The aggregate
purchase price of the Investor Warrants was $40,000.
 
    The Company also issued common stock warrants (collectively, the "Shattan
Warrants") to The Shattan Group, LLC (and certain of its affiliates), which
acted as the Company's placement agent for the sale of securities to MDP and
Olympus. The Shattan Warrants, which were issued as of June 6, 1997 and July 15,
1997, respectively, entitle the holders thereof to purchase an aggregate of
482,433 shares of Class B Common Stock at an exercise price of $4.81 per share
and expire on June 6, 2002 and July 15, 2002, respectively. The aggregate
purchase price of the Shattan Warrants was $4,824.
 
CANCELLATION OF COMMON STOCK
 
    In October 1997, the Company settled litigation that it had brought against
the former majority shareholder of CSB, and certain other directors and officers
of CSB arising out of the Company's acquisition of CSB in September 1996. As
part of that settlement, the Company canceled 424,182 shares of Class B Common
Stock that was recorded as a purchase price adjustment.

split of its common stock.

voting common stock and non-voting common stock.

    The projected benefit obligation was determined using weighted-average
assumed discount rates ranging from 6% to 7% for 1998 and 1997. The benefit
obligation is paid using Company assets upon the executive officers' death or
retirement.
 
RESTRICTED STOCK PLAN
 
    During 1997, the Company's shareholders approved the adoption of a
Restricted Stock Plan, providing for the issuance of common stock to the
Company's current president, subject to restrictions on sale or transfer. The
restrictions on sale or transfer expire over a period of four years which
coincides with the president's retirement. Under this plan 427,556 restricted
shares were issued with a market value of $2,012,000. This amount was recorded
as unearned compensation and is shown as a separate component of shareholders'
equity. Unearned compensation is being amortized to expense over the four-year
vesting period with expense of $503,000, and $503,000 recorded for 1998 and
1997, respectively.
 
    Whenever, during the term of employment of the Company's current president,
the Company issues common stock or a common stock equivalent, the Company's
president will be entitled to receive

additional shares of restricted stock. The number of shares of restricted stock
that will be issued to the Company's president will be equal to 3% of the sum of
(x) the number of shares of common stock then to be issued by the Company or, in
the case of the issuance of a common stock equivalent, the number of shares of
common stock that such common stock equivalent may be converted into or
exchanged for, and (y) the number of shares of restricted stock to be issued to
the Company's president at that time. In connection with the acquisition of
Antelope Valley Bank, the Company's president received approximately 86,000
shares of restricted stock with a market value of $989,000. The amount will be
recorded as unearned compensation during the year ending December 31, 1999 and
will be amortized to expense during the two-year vesting period.
 
STOCK OPTION PLAN
 
    In January 1997, the Company adopted the Option Plan pursuant to which the
Company's Board of Directors or the Compensation Committee (the "Committee") may
grant stock options to directors and certain officers of the Company or any of
its subsidiaries. As of December 31, 1998, there were approximately 728,600
shares of Class B Common Stock subject to the Option Plan. The Option Plan
provides only for the issuance of so-called "nonqualified" stock options (as
compared to incentive stock options). The options granted will vest over four
years, in half-year increments, with the first portion vesting on the 18-month
anniversary of the date of grant. The Option Plan provides that unless the
Committee otherwise determines, the options will have a six-year term, expiring
on the sixth anniversary of the date of grant.
 
    A summary of transactions in the Option Plan for the two years ended
December 31, 1998 follows:

    At December 31, 1998 29,959 shares were exercisable at prices ranging from
$9.64 to $10.52 per share. These shares had a weighted average remaining
contractual life of 4 years and a weighted average exercise price of $9.76.
 
    The maximum number of shares as to which options may be granted under the
Option Plan is sometimes referred to as the "Option Pool." Until such time as
the Company has Tier 1 Capital of $125.0 million or more, if the Company issues
any additional common stock or common stock equivalents, the number of shares in
the Option Pool automatically increases such that the number of shares in the
Option Pool will be equal to 6% of the sum of (i) the shares of common stock
(and common stock equivalents) issued and outstanding immediately following such
issuance and (ii) the number of shares in the Option Pool. As a consequence of
the Company's issuance of common stock in the acquisition of Antelope Valley

Bank, the number of shares in the Option Pool increased by approximately 182,800
to approximately 911,400. On a pro forma basis giving effect to the acquisition
of Antelope Valley Bank, the Company had Tier 1 capital of $79.6 million at
December 31, 1998.
 
    The Company applies APB Opinion 25 in accounting for its Options Plan, and
accordingly, no compensation cost has been recognized for its stock options in
the supplemental consolidated financial statements. Had the Company determined
compensation cost based on the fair value at the grant date for its stock
options under the methodology prescribed under SFAS 123, the Company's net
earnings and earnings per share for 1998 and 1997 would have been reduced to the
pro forma amounts indicated below. The per share weighted-average fair value of
the stock options granted during 1998 and 1997 was $3.36 and $2.46,
respectively. The fair value of each option grant is estimated on the date of
grant using the Black-Scholes option-pricing model with the following
assumptions: expected dividend yield 0.0%, risk-free interest rate of 5.0%, an
expected life of 6 years and expected volatility of 20%.

NOTE 14--CAPITAL ADEQUACY:
 
    The Bank is subject to various regulatory capital requirements established
by the federal banking agencies. Failure to meet minimum capital requirements
can initiate certain mandatory and possibly additional discretionary actions by
regulators that, if undertaken, could have a direct material effect on the
Bank's financial statements. Under capital adequacy guidelines and the
regulatory framework for prompt corrective action, the Banks must meet specific
capital guidelines that involve quantitative measures of the Banks' assets,
liabilities and certain off-balance sheet items as calculated under regulatory
accounting practices. The Banks' capital amounts and classifications are also
subject to qualitative judgment by the regulators about components, risk
weighting, and other factors.
 
    Quantitative measures established by regulation to ensure capital adequacy
require the Banks to maintain minimum amounts and ratios (set forth in the table
below) of total and Tier 1 capital (as defined in the regulations) to
risk-weighted assets (as defined), and of Tier I capital (as defined) to average
assets (as defined). Management believes, as of December 31, 1998, that the
Banks meets all capital adequacy requirements to which they are subject.
 
    As of December 31, 1998, the most recent notification from the Department of
Financial Institutions (DFI) categorized the Eldorado Bank as adequately
capitalized and Antelope Valley Bank as well capitalized under the regulatory
framework for prompt corrective action. To be categorized as adequately

NOTE 15--FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK:
 
    In the ordinary course of business, the Company enters into various types of
transactions which involve financial instruments with off-balance sheet risk.
These financial instruments include commitments to extend credit and sell loans,
standby letters of credit, forward commitments to sell mortgage-backed
securities and put options to sell mortgage-backed securities and are not
reflected in the accompanying consolidated statement of financial condition.
These financial instruments carry various degrees of credit and market risk.
Credit risk is defined as the possibility that a loss may occur from the failure
of another party to perform according to the terms of the contract. Market risk
is the possibility that future changes in market prices will make a financial
instrument less valuable. Management does not anticipate that the settlement of
these financial instruments will have a material adverse effect on the Company's
financial position or results of operations.

    The Company is principally engaged in providing commercial loans and leases
with interest rates that fluctuate with the various market indices and
variable-rate real estate loans. These loans are primarily funded through
short-term demand deposits and certificates of deposit with fixed rates. The
contractual amounts of commitments to extend credit, standby and commercial
letters of credit represent the amount of credit risk. Since many of the
commitments and letters of credit are expected to expire without being drawn,
the contractual amounts do not necessarily represent future cash requirements.
 
    Commitments to extend credit are agreements to lend to a customer as long as
there are no violations of any conditions established in the contract. The
Company evaluates the creditworthiness of each customer. The amount of
collateral obtained, if deemed necessary by the Company upon the extension of
credit, is based upon management's evaluation. Collateral varies, but may
include securities, accounts receivable, inventory, personal property,
equipment, income property, commercial and residential property. Commitments
generally have fixed expiration dates or other terminal clauses and may require
the payment of fees. The Company experiences interest rate risk on commitments
to extend credit which are at fixed rates. There were no fixed rate commitments
at December 31, 1998 or 1997.
 
    Standby letters of credit are written conditional commitments issued by the
Company to guarantee the performance of a customer to a third party, generally
in the production of goods and services or under contractual commitments in the
financial market. The credit risk involved in issuing letters of credit is
essentially the same as that involved in extending loan facilities to customers.
The Company uses the same underwriting policies as if a loan were made.
 
    Eldorado Bank's policy is to hedge a portion of its mortgage loans held for
sale and its commitments to originate mortgage loans against interest rate risk
with forward commitments to sell, or put options on, mortgage-backed securities.
Forward commitments are contracts for delayed delivery of securities in which
Eldorado Bank agrees to make delivery at a specified future date of a specified
security, at a specified price or yield. Put options convey to Eldorado Bank the
right, but not the obligation, to sell the securities at a contractually
specified price. Risks arise from the possible inability of counterparties to
meet the terms of their contracts and from movements in securities' values and
interest rates. Eldorado Bank tries to minimize these risks by dealing with only
primary brokers and maintaining correlation with the asset or commitment being
hedged. Eldorado Bank monitors its exposure through the use of valuation models
provided by a financial advisory service. The unrealized losses on open forward
contracts to sell mortgage-backed securities were $108,000 and $44,000 as of
December 31, 1998 and 1997, respectively. There were no unrealized losses on
open put options to sell mortgage-backed securities as of December 31, 1998 and
1997.

NOTE 15--FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK: (CONTINUED)
 
    Commitments to sell loans are agreements to sell loans originated by
Eldorado Bank to investors. These commitments may be optional or mandatory.
Under an optional commitment, a commitment fee is paid and Eldorado Bank carries
no risk in excess of the loss of such fee in the event that Eldorado Bank is
unable to deliver the loans into the commitment. Mandatory commitments may
entail possible financial risk to Eldorado Bank if it is unable to deliver the
loans in sufficient quantity or at sufficient rates for commitments which are at
a fixed rate. There were commitments of $94,000,000 and $26,000,000 at December
31, 1998 and 1997. At December 31, 1998 the commitments were a combination of
fixed and adjustable rate loans with coupons ranging from 5.5% to 7.00% and with
settlement dates ranging from January 14, 1999 to February 22, 1999. Eldorado
Bank had closed loans at December 31, 1998 of $43,287,000 with which to satisfy
those commitments and a pipeline of unclosed loans of $89,732,000 that, in
management's opinion, will be sufficient to fulfill the balance of the
commitment.

CASH AND FEDERAL FUNDS SOLD
 
    For cash and Federal funds sold the carrying amount is a reasonable estimate
of fair value.
 
INVESTMENT SECURITIES
 
    All investment securities are marketable and have an easily determined
market value. Market quotes are used in determining the fair value.
 
LOANS AND LEASES RECEIVABLE
 
    Loans were broken into fixed and variable rate loans for this analysis. The
credit risk component of the fair value analysis is assumed to be approximated
by the loan and lease loss reserve. A separate analysis is conducted on the
adequacy for the allowance for loan and lease losses and should be a reasonable
proxy for this credit risk component.

NOTE 16--DISCLOSURES ABOUT FAIR VALUES OF FINANCIAL INSTRUMENTS: (CONTINUED)
    Fixed rate commercial and consumer loans are valued using a discounted cash
flow model that assumes a prepayment rate of 10% and a discount rate of prime
plus 50 basis points. These commercial and consumer loans were grouped into
categories and the weighted average maturity and rate were used in computing the
future cash flows. Leases are regularly sold into the secondary market and on
average have sold at a premium of approximately 3%. To determine the fair value
of leases, this potential sale premium was discounted to par to account for the
delinquent leases that would not garner the same sale premium. Fixed rate
residential mortgage loans were valued at par realizing that any premiums
attributable to the performing portfolio would be offset by discounts in the
delinquent portion of the portfolio.
 
    Variable rate loans were broken down by loan type and evaluated based upon
the current weighted average rate of the loans in comparison to current market
conditions. Premiums of up to 2% were applied to those groups of loans that had
higher than market rates while loans at or below market were discounted.
 
MORTGAGE LOANS HELD FOR SALE
 
    Loans held for sale are valued at a premium of 1%. These loans consist of
residential mortgage loans and are largely a fixed rate product. The premium
used approximates the gain that would be recognized on the sale of these loans,
discounted for hedging and sales costs.
 
DEPOSITS
 
    Deposits consist of both non-interest and interest bearing accounts. Each
type of account has been valued differently as described below.
 
    Non-interest bearing demand--Core non-interest bearing deposits are a
premium account for commercial banks and as such have been valued with a factor
of .95. Non-core type accounts such as title company deposits and custodial
accounts have been valued at par due to their temporary and volatile nature.
 
    Interest bearing demand, savings and money market accounts--These accounts
are all priced competitively in the marketplace and are low cost funds for the
Bank. As such, these deposits have also been ascribed as premium accounts and
valued with a factor of .99.
 
    Certificates of deposit--Certificates of deposit accounts ("CD") were marked
to market utilizing current CD rates compared to rates being paid. CDs were
grouped based upon their remaining maturities and the weighted average maturity
and rates were grouped based upon their remaining maturities and the weighted
average maturity and rates were utilized in the analysis. Current rates for CDs
were determined utilizing the Treasury rates for comparable maturities less 25
basis points.
 
    Generally, rates currently being paid are higher than current market rates
which results in these accounts having a lower fair value.
 
BORROWINGS
 
    Federal funds purchased are over-night investments and the carrying value is
a reasonable estimate of fair value. For subordinated debentures, having been
recently priced at the issuance in 1997, the carrying value is a reasonable
estimate of fair value.

    The note payable to related parties has a maturity of 15 months and is

OFF-BALANCE SHEET FINANCIAL INSTRUMENTS
 
    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 counterparties. 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 counterparties at the reporting date. The fair value of commitments to
extend credit and standby letters of credit is not material.
 
    Forward Commitments to Sell Mortgage-Backed Securities--Fair value is based
on quoted prices for financial instruments with identical or similar terms. The
fair value of forward commitments to sell mortgage-backed securities is not
material.
 
    Put Options to Sell Mortgage-Backed Securities--Fair value is derived from
active exchange quotations. The fair value of put options to sell
mortgage-backed securities is not material.
 
NOTE 17--COMMITMENTS AND CONTINGENCIES:
 
LITIGATION
 
    As of December 31, 1998, no litigation was pending against the Company
itself. Eldorado Bank is the defendant in an action filed in 1994 by a former
CSB loan production officer alleging wrongful termination, breach of contract,
defamation and various other causes of action. In October 1997, a jury awarded
the former employee $3.8 million in damages, including $2.0 million in punitive
damages. The trial court subsequently reduced the award to $2.0 million,
including $500,000 in punitive damages. In conjunction with this initial
judgment, the Bank recorded a reserve for the full amount of the judgment. Both
the Company and its former employee have filed appeals, with the former employee
seeking to have the total amount of the jury's punitive damage award reinstated.
Interest accrues on the judgment at the statutory rate of 10% and as of December
31, 1998 the judgment, including interest, was equal to $2.6 million. There can
be no assurance, however, that the Company will not incur additional expense in
connection with such matter or that an adverse outcome in the appeal will not
have a material adverse effect on the Company's results of operations.
 
    The Company is from time to time subject to various legal actions (in
addition to that described above) which are considered to be part of its normal
course of business. Management, after consultation with legal counsel, does not
believe that the ultimate liability, if any, arising from those other actions
will have a materially adverse effect on the financial position or results of
operations of the Company.

    It is expected that in the normal course of business, expiring leases will

    Rent expense under all noncancellable operating lease obligations aggregated
$2,636,000, $2,389,000 and $1,190,000 for the years ended December 31, 1998,
1997 and 1996, respectively.
 
DIVIDEND RESTRICTIONS
 
    Federal Reserve policies declare that a bank holding company may not pay
cash dividends on its common stock unless its net income is sufficient to fund
fully such dividend, and its prospective rate of earnings retention after the
payment of such dividend appears consistent with its capital needs, asset
quality and overall financial condition. In connection with the Eldorado
Acquisition, the Company agreed that it will not pay dividends on common stock
without the prior approval of the Federal Reserve.
 
    The Company is a legal entity separate and distinct from the Banks.
Substantially all of the Company's revenues and cash flow, including funds
available for the payments of dividends and other operating expenses, consists
of dividends paid to the Company by the Banks. There are statutory and
regulatory limitations on the amount of dividends which may be paid to the
Company by the Banks. Dividends payable by each of the Banks is restricted under
California law to the lesser of the Bank's retained earnings, or the Bank's net
income for the latest three fiscal years, less dividends previously declared
during that period, or, with the approval of the DFI, to the greater of the
retained earnings of the Bank, the net income of the Bank for its last fiscal
year or the net income of the Bank for its current fiscal year. In connection
with the Eldorado Acquisition, Eldorado Bank paid a dividend of $14 million,
which exceeded the Bank's net income for the previous three fiscal years. As a
result, Eldorado Bank must obtain the approval of the DFI with respect to the
payment of any dividend up to the greater of Eldorado Bank's retained earnings,
the net income of Eldorado Bank for its last fiscal year and the net income of
the Bank for its current fiscal year. In no event can Eldorado Bank issue a
dividend in excess of such amounts.
 
    Federal Reserve regulations also limit the payment of dividends by a state
member bank such as Eldorado Bank. Under Federal Reserve regulations, dividends
may not be paid unless both undivided profits and earnings limitations have been
met. First, no dividend may be paid if it would result in a withdrawal of
capital or exceed the bank's undivided profits as reported in its most recent
Report of Condition and Income, without the prior approval of the Federal
Reserve and two-thirds of the shareholders of each class of stock outstanding.
Second, a state member bank may not pay a dividend without the prior written
approval of the Federal Reserve if the total of all dividends declared in one
year exceeds the total of net income for that year plus its retained net income
for the preceding two calendar years.

NOTE 17--COMMITMENTS AND CONTINGENCIES: (CONTINUED)
    The payment of dividends on capital stock by the Company and the Banks may
also be limited by other factors, including applicable regulatory capital
requirements and broad enforcement powers of the federal regulatory agencies.
Both the Federal Reserve and the DFI have broad authority to prohibit the
Company and the Banks from engaging in practices which the banking agency
considers to be unsafe or unsound. It is possible, depending upon the financial
condition of the Banks or the Company and other factors, that the applicable
regulator may assert that the payment of dividends or other payments by one or
both of the Banks or the Company is an unsafe or unsound practice and,
therefore, implement corrective action to address such a practice. Among other
things, Federal Reserve 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 and tax sharing payments
which do not reflect the taxes actually due and payable.
 
    The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
generally prohibits a depository institution from making any capital
distribution (including payment of a dividend) or paying any management fee to
its holding company if the depository institution would thereafter be
"undercapitalized" for regulatory purposes. Those regulations and restrictions
may limit the Company's ability to obtain funds from the Banks for its cash
needs, including funds for payment of interest and operating expenses and
dividends.
 
NOTE 18--OPERATING SEGMENTS:
 
    The Company has determined that its reportable segments are the operations
pertaining to mortgage banking ("Mortgage") and the operations pertaining to
commercial and consumer banking ("Commercial and Consumer"). Commercial and
Consumer includes the operations of the Company's equipment leasing division.
The segment labeled "Other" primarily consists of the Company's administrative
function which is responsible for investment and borrowing activities and other
administrative services. The financial results of the Company's operating
segments are presented on an accrual basis. There are no significant differences
among the accounting policies of the segments as compared to the Company's
consolidated financial statements. The Company evaluates the performance of its
segments based on net interest income, non-interest income, net income and total
assets. Funds are allocated as needed from Commercial Banking to Mortgage at a
rate comparable to the prime rate less 2.25%.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholders of
Eldorado Bancshares, Inc.
 
In our opinion, the accompanying consolidated statement of condition and the
related consolidated statements of income, of shareholders' equity and of cash
flows present fairly, in all material respects, the financial position of
Eldorado Bancshares, Inc. (formerly Commerce Security Bancorp, Inc.) and its
subsidiaries (the "Company") at December 31, 1998 and 1997, and the results of
their operations and their cash flows for the years then ended in conformity
with generally accepted accounting principles. 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 of these statements in accordance with generally accepted auditing
standards which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                        DECEMBER 31, 1998, 1997 AND 1996
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
BASIS OF PRESENTATION
 
    Eldorado Bancshares, Inc. (formerly Commerce Security Bancorp, Inc.), a
Delaware corporation and bank holding company, and its wholly-owned subsidiaries
Eldorado Bank and CSBI Capital Trust I are included in the accompanying
consolidated financial statements and are collectively referred to as the
"Company" or the "Bank". Significant intercompany transactions and accounts have
been eliminated.
 
    Prior to June 1997 and the acquisition of Eldorado Bank, the Company had
three subsidiaries, Commerce Security Bank (CSB), Liberty National Bank (LNB),
and San Dieguito National Bank (SDNB). On June 30, 1997, the Company merged the
then existing three subsidiaries into the newly acquired Eldorado Bank.
Following those transactions, the organizational structure consists of Company
and its one wholly owned banking subsidiary, Eldorado Bank.
 
BUSINESS
 
    The Bank offers a broad range of commercial banking services primarily in
Southern California and in the Sacramento area of Northern California, catering
especially to small business. The Bank offers commercial, real estate, consumer,
Small Business Administration-guaranteed loans as well as checking and savings
deposits, corporate cash management, international banking services, safe
deposit boxes, collection, traveler's checks, notary public and other customary
non-deposit banking services.
 
RISKS AND UNCERTAINTIES
 
    In the normal course of its business, the Company encounters two significant
types of risk: economic and regulatory. Economic risk is comprised of three
components--interest rate risk, credit risk and market risk. The Company is
subject to interest rate risk to the degree that its interest-bearing
liabilities mature and reprice at different speeds, or on a different basis,
than its interest-bearing assets. Credit risk is the risk of default on the
Company's loan portfolio that results from the borrower's inability or
unwillingness to make contractually required payments. Market risk results from
changes in the value of assets and liabilities which may affect, favorably or
unfavorably, the realizability of those assets and liabilities.
 
    The Company is subject to the regulations of various governmental agencies.
These regulations can and do change significantly from period to period. The
Company is also subject to periodic examinations by the regulatory agencies,
which may subject it to changes in asset valuations, in amounts of required loss
allowances and in operating restrictions resulting from the regulators'
judgments based on information available to them at the time of their
examination.
 
RECENTLY ISSUED ACCOUNTING STANDARDS
 
    In June 1997 the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards 130, "Reporting Comprehensive
Income" (SFAS 130). This Statement provides that all enterprises report
comprehensive income as a measure of overall performance. Comprehensive income
is the change to equity (net assets) of a business during a period. The
Statement includes the guidelines for the calculations and required
presentations. The Company implemented this standard in 1998.
 
    In June 1997 the FASB issued SFAS 131, "Disclosures About Segments of an
Enterprise and Related Information." This statement changed the way public
companies report information about segments of
 
                                      F-53

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                        DECEMBER 31, 1998, 1997 AND 1996
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
their business in their annual financial statements and requires them to report
selected segment information in their quarterly reports issued to shareholders.
Companies are required to disclose segment data based upon how management makes
decisions about allocating resources to segments and measuring performance. The
Company implemented this standard in 1998.
 
    In February 1998 the FASB issued SFAS 132, "Employer's Disclosures about
Pensions and other Post-Retirement Benefits." This Statement standardizes the
disclosure requirements for pensions and other post-retirement benefits to the
extent practicable. The Company implemented this standard in 1998.
 
    In June 1998 the FASB issued SFAS 133, "Accounting for Derivative
instruments and Hedging Activities." This Statement establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts, (collectively referred to as
derivatives) and for hedging activities. It requires that an entity recognize
all derivatives as either assets or as liabilities in the statement of financial
position and measure those instruments at fair value. For the Company, this new
standard is effective January 1, 2000 and is not to be applied retroactively to
financial statements of prior periods. The impact of this Statement, if any, is
yet to be determined.
 
    In October 1998, the FASB issued SFAS 134, "Accounting for Mortgage-Backed
Securities Retained after the Securitization of Mortgage Loans Held For Sale by
a Mortgage Banking Enterprise." This Statement establishes accounting and
reporting standards for securitization of mortgage loans. For the Company, this
new standard is effective January 1, 1999. The impact of this Statement, if any,
is yet to be determined.
 
CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents include cash and due from banks and federal funds
sold. Generally, federal funds sold are sold for one-day periods.
 
INVESTMENT SECURITIES
 
    The Company has classified its investment securities as held-to-maturity and
available-for-sale. No trading portfolio is maintained. Investment securities
are segregated in accordance with management's intention regarding their
retention.
 
    Investment securities classified as held-to-maturity are carried at cost,
adjusted for the amortization of premiums and the accretion of discounts.
Premiums and discounts are amortized and accreted to operations using the
straight line method, which management believes approximates the interest
method. Management has the intent and ability to hold these assets as long-term
investments until their expected maturities. Under certain circumstances,
including the significant deterioration of the issuer's credit worthiness or a
significant change in tax-exempt status or statutory or regulatory requirements,
securities classified as held-to-maturity may be sold or transferred to another
classification.
 
    Investment securities classified as available-for-sale may be held for
indefinite periods of time and may be sold to implement the Company's
asset/liability management strategies and in response to changes in interest
rates and/or prepayment risk and similar factors. These securities are recorded
at estimated fair value. Unrealized gains and losses are reported as other
comprehensive income in the consolidated statement of shareholders' equity, net
of income taxes.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                        DECEMBER 31, 1998, 1997 AND 1996
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    Gains and losses on investment securities are determined on the specific
identification method and are included in other income.
 
LOANS HELD FOR SALE
 
    Loans held for sale consists of mortgage loans carried at lower of cost or
fair value on an aggregate basis.
 
LOANS AND LEASES
 
    Loans are stated at principal amounts outstanding, net of unearned income,
including discounts and fees. Net deferred fees and costs are generally deferred
and amortized into interest income over the contractual life of the related
loans as a yield adjustment. Direct financing leases, which include estimated
residual values of leased equipment, are carried net of unearned income. Income
from these leases is recognized on a basis which produces a level yield on the
outstanding net investment in the lease. The production of new leases comes
exclusively from the wholesale sector through a network of brokers. The Company
services these leases and, beginning in 1997, sells blocks of leases from time
to time to other institutions. Leases held for resale are carried at the lower
of cost or estimated fair value on an aggregate basis. Gains and losses on the
sale of leases are recognized upon delivery based on the difference between
selling price and carrying value.
 
NON-ACCRUAL / IMPAIRED LOANS
 
    When payment of principal or interest on a loan is delinquent for 90 days,
or earlier in some cases, the loan is placed on nonaccrual status, unless the
loan is in the process of collection and the underlying collateral fully
supports the carrying value of the loan. When a loan is placed on nonaccrual
status, interest accrued during the period prior to the judgment of
uncollectibility is charged to operations. Generally, any payments received on
nonaccrual loans are applied first to outstanding loan amounts and next to the
recovery of charged-off loan amounts. Any excess is treated as recovery of lost
interest.
 
    SFAS 114 requires that impaired loans be measured based on the present value
of expected future cash flows discounted at the loan's effective interest rate,
the loan's observable market price, or the fair value of the collateral if the
loan is collateral dependent. When the measure of the impaired loan is less than
the recorded balance of the loan, the impairment is recorded through a valuation
allowance included in the allowance for loan and lease losses.
 
    The Company considers all loans impaired when it is probable that both
interest and principal will not be collected in accordance with the contractual
terms of the agreement. All loans that are ninety days or more past due, or have
been restructured to provide a reduction in the interest rate or a deferral of
interest or principal are automatically included in this category.
 
ALLOWANCE FOR ESTIMATED LOAN AND LEASE LOSSES
 
    A provision for estimated loan and lease losses is charged to expense when,
in the opinion of management, such losses are inherent in the portfolio. The
allowance is increased by provisions charged to expense, increased for
recoveries of loans previously charged-off, and reduced by charge-offs. Loans
and leases are charged-off when management believes that the collectibility of
the principal is unlikely.

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
Management's estimates are used to determine the allowance that is considered
adequate to absorb losses inherent in the existing loan and lease portfolio.
These estimates are inherently subjective and their accuracy depends on the
outcome of future events. Ultimate losses may differ from current estimates.
Management's estimates are based on historical loan loss experience, specific
problem loans and leases, current economic conditions that may impact the
borrower's ability to pay, volume, growth and composition of the loan portfolio,
value of the collateral and other relevant factors.
 
MORTGAGE BANKING ACTIVITIES
 
    The Company originates and sells residential mortgage loans to a variety of
secondary market investors, including the Federal Home Loan Mortgage Corporation
(FHLMC or Freddie Mac), the Federal National Mortgage Association (FNMA or
Fannie Mae) and others. The Company has an arrangement with the Government
National Mortgage Association (GNMA or Ginnie Mae) whereby loans originated by
the Company are securitized by GNMA and sold to others. Gains and losses on the
sale of mortgage loans are recognized upon delivery based on the difference
between the selling price and the carrying value of the related mortgage loans
sold. Deferred origination fees and expenses are recognized at the time of sale
in the determination of the gain or loss. The Company sells the servicing for
such loans to either the purchaser of the loans or to a third party. The Company
recognizes the gain or loss on servicing sold when all risks and rewards of
ownership have transferred.
 
    Mortgage loans held for sale are stated at the lower of cost or market as
determined by the outstanding commitments from investors or current investor
yield requirements calculated on an aggregate loan basis. Valuation adjustments
are charged against noninterest income.
 
    Forward commitments to sell and put options on mortgage-backed securities
are used to reduce interest rate risk on a portion of loans held for sale and
anticipated loan fundings. The resulting gains and losses on forward commitments
are deferred and included in the carrying values of loans held for sale.
Premiums on put options are capitalized and amortized over the option period.
The Company expects that, in general, gains and losses on forward commitments
and put options deferred against loans held for sale will approximately offset
equivalent amounts of unrecognized gains and losses on the related loans.
Forward commitments to sell and put options on mortgage-backed securities that
hedge anticipated loan fundings are not reflected in the consolidated statement
of financial condition. Gains and losses on these instruments are not recognized
until the actual sale of the loans held for sale. In 1996, the Company sold its
portfolio of loan servicing and no longer services mortgage loans for others.
 
SBA LENDING
 
    The Company is qualified as a "Preferred Lender" under the SBA programs,
allowing it to originate SBA loans based on its own underwriting decisions and
without prior approval of the SBA. The Company sells the government guaranteed
portion of the SBA loans at a premium, a portion of which is immediately
recognized as income. The remaining portion of the premium, representing the
estimated normal servicing fee retained by the Company, is capitalized and
recognized as income over the estimated life of the loan.

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
LOAN SERVICING RIGHTS
 
    Loan servicing rights are accounted for under the provisions of SFAS 125,
"Accounting for Transfers and Servicing of Financial Assets and Extinguishments
of Liabilities," which became effective January 1, 1997. SFAS 125 superseded
SFAS 122, "Accounting for Mortgage Servicing Rights," but did not significantly
change the methodology used to account for servicing rights. The servicing
rights currently capitalized, included in other assets, are the result of
servicing rights retained on sold SBA loans and are being amortized in
proportion to and over the period of estimated servicing income. Management
stratifies servicing rights based on origination period and interest rate and
evaluates the recoverability in relation to the impact of actual and anticipated
loan portfolio prepayment, foreclosure, and delinquency experience. The Company
did not have a valuation allowance associated with the servicing rights
portfolio as of December 31, 1998 and 1997.
 
PREMISES AND EQUIPMENT
 
    Premises and equipment are carried at cost less accumulated depreciation and
amortization. Depreciation on furniture, fixtures and equipment is computed
using the straight-line method over the estimated useful lives, which range from
two to fifteen years. Leasehold improvements are amortized using the
straight-line method over the estimated useful lives of the improvements or the
remaining lease term, whichever is shorter. Expenditures for betterments or
major repairs are capitalized and those for ordinary repairs and maintenance are
charged to operations as incurred.
 
REAL ESTATE ACQUIRED THROUGH FORECLOSURE
 
    Real estate acquired in settlement of loans is recorded at the lower of the
unpaid balance of the loan at settlement date or the fair value less estimated
costs to sell. A valuation allowance is established to reflect declines in value
subsequent to foreclosure, if any, below the new basis. Required developmental
costs associated with foreclosed property under construction are capitalized and
considered in determining the fair value of the property. Operating expenses of
such properties, net of related income, and gains and losses on their
disposition are included in other non-interest expenses.
 
INTANGIBLES ARISING FROM ACQUISITIONS
 
    The Company has paid amounts in excess of fair value for CSB's, LNB's, and
Eldorado's core deposits and tangible assets. Such amounts are being amortized
by systematic charges to income (primarily for periods from 10 to 25 years) over
a period which is no greater than the estimated remaining life of the assets
acquired or not to exceed the estimated average remaining life of the existing
deposit base assumed. The Company periodically reviews intangibles to assess
recoverability and an impairment is recognized in operations if a permanent loss
of value occurs.
 
FEDERAL AND STATE TAXES
 
    The Company provides for income taxes under the provisions of SFAS 109,
"Accounting for Income Taxes." Under the liability method which is prescribed by
SFAS 109, a deferred tax asset and/or liability is computed for both the
expected future impact of differences between the financial statement and tax
bases of assets and liabilities, and for the expected future tax benefit to be
derived from tax loss and tax credit

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
carryforwards. SFAS 109 also requires the establishment of a valuation
allowance, if necessary, to reflect the likelihood of the realization of
deferred tax assets. The effect of tax rate changes will be reflected in income
in the period such changes are enacted.
 
    Deferred income taxes are provided by applying the statutory tax rates in
effect at the balance sheet date to temporary differences between the book basis
and the tax basis of assets and liabilities. The resulting deferred tax assets
and liabilities are adjusted to reflect changes in tax laws or rates.
 
STOCK-BASED COMPENSATION
 
    On January 1, 1997, the Company adopted SFAS 123, "Accounting for
Stock-Based Compensation", which permits entities to recognize, as expense over
the vesting period, the fair value of all stock-based awards on the date of
grant.
 
    Alternatively, SFAS 123 also allows entities to continue to apply the
provisions of Accounting Principles Board (APB) Opinion 25 and provide pro forma
net income and pro forma earnings per share disclosures for employee stock
option grants as if the fair-value-based method defined in SFAS 123 had been
applied. The Company has elected to continue to apply the provisions of APB
Opinion 25, which requires compensation expense be recorded on the date of grant
only if the current market price of the underlying stock exceeds the exercise
price, and provide the pro forma disclosure provisions of SFAS 123. See Note 13
of the Notes to Consolidated Statements for the pro forma net income and pro
forma earnings per share disclosures.

ESTIMATES
 
    The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets, liabilities and
disclosures in the consolidated financial statements. Actual results could
differ from those estimates.
 
NOTE 2--ACQUISITIONS AND 1996 REORGANIZATION:
 
    A key element of the Company's strategic plan includes building
profitability through acquisitions of community banks principally, but not
exclusively, in and around its Southern California base, including banks that
have underperformed relative to their peers but have strong lending franchises,
niche business lines or low cost deposits that would complement our existing
operations and branch network and also provide opportunities for cost savings
through branch overlap and back-office consolidation. From September 1995 to
December 31, 1998, the Company completed three acquisitions, increasing the
Company's assets by over $840 million, including the acquisition, completed on
June 6, 1997, of Eldorado

NOTE 2--ACQUISITIONS AND 1996 REORGANIZATION: (CONTINUED)
Bancorp ("Eldorado") and its bank subsidiary, Eldorado Bank, a community bank
based in Tustin, California with approximately $400 million in total assets
(collectively with the financing related thereto, the "Eldorado Acquisition").
Effective June 30, 1997, the Company consolidated via mergers (collectively, the
"Bank Mergers") into Eldorado Bank the respective operations of its other
subsidiaries--LNB, SDNB, and CSB.
 
    On March 31, 1996, the Company's predecessor, SDN Bancorp, Inc. ("SDN")
completed its acquisition of LNB (the "Liberty Acquisition") for approximately
$15.1 million in cash. LNB had total assets of approximately $150 million as of
the acquisition date.
 
    As of September 1, 1996, the Company completed the plan of reorganization
(the "1996 Reorganization") contemplated by the Agreement and Plan of
Reorganization dated April 23, 1996 (the "Agreement") between SDN and CSB. As
part of the 1996 Reorganization, SDN became a subsidiary of the Company,
effective August 31, 1996, in a transaction in which SDN shareholders received
shares of the Company's common stock in exchange for all of the outstanding
shares of SDN common stock. As of September 1, 1996, the Company completed the
acquisition of CSB (the "Commerce Acquisition") in which the Company acquired
all of the outstanding shares of CSB. Pursuant to the Agreement, holders of CSB
common stock received approximately $14.1 million and a total of 1,543,691
shares of the Company. CSB had total assets of approximately $220 million at
September 1, 1996.
 
    Effective June 6, 1997, the Company completed the Eldorado Acquisition. The
Acquisition was effected pursuant to an Agreement and Plan of Merger entered
into between the Company and Eldorado on December 24, 1996 (the "Acquisition
Agreement"). Pursuant to the Acquisition Agreement, the Company acquired 100% of
the outstanding stock of Eldorado for cash consideration of $23.00 per share.
Contemporaneously with the Acquisition, each Eldorado stock option that had not
previously been exercised (collectively, the "Eldorado Options") was canceled in
return for payment by Eldorado of the difference between the $23.00 price per
share and the exercise price thereof. The aggregate consideration paid to
holders of Eldorado common stock and Eldorado Options (net of the tax benefit
arising out of the Eldorado Options) was approximately $90.3 million. Eldorado
had total assets of approximately $400 million at June 6, 1997.
 
    The Liberty, Commerce, and Eldorado Acquisition's were accounted for using
the purchase method of accounting in accordance with APB Opinion 16, "Business
Combinations". Under this method of accounting, the purchase price was allocated
to the assets acquired and deposits and liabilities assumed based on their fair
values as of the acquisition date. The consolidated financial statements include
the operations of LNB, CSB, and Eldorado from the date of acquisition.
Intangibles arising from the transactions totaled approximately $3.8 million in
the Liberty Acquisition, $7.2 million in the Commerce Acquisition and
approximately $50.2 million in the Eldorado Acquisition. Certain preacquistion
contingency reserves were established as of the acquisition dates that are
subject to adjustment during the "allocation period" in accordance with SFAS 38
"Accounting for Preacquisition Contingencies." The fair value of CSB has been
adjusted to reflect the resolution of these contingencies established relating
to certain litigation, writedowns of real estate owned and a settlement with the
principal shareholder of CSB.

    For purposes of the maturity table, mortgage-backed securities, which are
not due at a single maturity date, have been allocated over maturity groupings
based on the weighted-average contractual maturities of the underlying
collateral. The mortgage-backed securities may mature earlier than their
weighted-average contractual maturities because of principal prepayments.

NOTE 6--MORTGAGE BANKING ACTIVITIES:
 
    The Bank originates and sells residential mortgage loans to secondary market
investors subject to certain recourse provisions. At December 31, 1998 and 1997,
the Bank had sold loans with recourse with an unpaid principal balance of
$84,194,000 and $86,568,000, respectively. The Bank had recorded a reserve of
$397,000 and $1,076,000, in connection with such sales at December 31, 1998 and
1997, respectively. During 1998 and 1997, the Bank added to this reserve $-0-
and $2,021,000, respectively, and charged off $679,000 and $1,645,000,
respectively to this account related to these repurchase obligations. In
management's opinion, these reserves are adequate to absorb losses inherent in
the outstanding recourse obligations.

NOTE 10--BORROWINGS:
 
MANDATORY CONVERTIBLE DEBENTURES
 
    In conjunction with the Bank Mergers on June 30, 1997, the Company assumed
certain obligations of its subsidiary SDN Bancorp. Among these obligations were
mandatory convertible debentures that totaled approximately $537,000. The
debentures were mandatorily convertible at March 30, 1998 into the Company's
common stock, at a rate equal to the lower of: (i) $52.50 per share (subject to
certain anti-dilutive adjustments and the power of the Company's Board of
Directors to reduce the conversion price), or (ii) the then current fair market
value per share of the Company's common stock. At the Company's option, the
debentures were redeemed on March 27, 1998 at 100% of par. The Company funded
the redemption of the debentures by entering into a note payable with Dartmouth
Capital Group, L.P. which matures on March 31, 2000. The note bears interest at
10.5% annually, with principal and interest payments payable in quarterly
installments. At December 31, 1998, the outstanding principal balance on the
note was $338,000.
 
SUBORDINATED DEBENTURES
 
    In June 1997, CSBI Capital Trust I (the "subsidiary trust"), issued
$27,657,000 of 11 3/4% Trust Originated Preferred Securities (the "preferred
securities"). In connection with the subsidiary trust's issuance of the
preferred securities, the Company issued to the subsidiary trust $27,657,000
principal amount of its 11 3/4% subordinated debentures, due June 6, 2027 (the
"subordinated debentures"). The sole assets of the subsidiary trust are and will
be the subordinated debentures. The Company's obligation under the subordinated
debentures and related agreements, taken together, constitute a firm and
unconditional guarantee by the Company of the subsidiary trust's obligation
under the preferred securities.

NOTE 12--SHAREHOLDERS' EQUITY: (CONTINUED)
COMMERCE ACQUISITION
 
    Prior to August 31, 1996, the Partnership invested approximately $14.5

investment, SDN issued a total of 3,664,776 additional shares of SDN common
stock at a price per share of $3.95 pursuant to a subscription agreement entered
into in March 1996. At the Partnership's direction, SDN issued 1,080,000 of

outstanding prior to the 1996 Reorganization and the Commerce Acquisition.
Holders of CSB common stock were issued 1,527,540 shares of Company common stock

the Company's common stock and cash of approximately $346,000 are held in escrow
pending final resolution of the SAIF recapitalization. As a result of
legislation that recapitalized the SAIF, passed on September 30, 1996, the stock
and cash escrows were distributed, with approximately $96,000 disbursed in cash
and 16,151 common shares distributed.
 
ELDORADO ACQUISITION.
 
    Approximately $94.8 million of cash was necessary to pay the cash
consideration to holders of Eldorado common stock and Eldorado stock options and
Eldorado Acquisition-related expenses incurred by the Company, of which $14.0
million was funded from Eldorado's excess capital and $80.3 million was raised
through the Company's sale, effective June 6, 1997, of Class B Common Stock,
Special Common Stock, a Junior Subordinated Debenture (and, indirectly, Series A
Capital Securities), Series B Preferred Stock and common stock warrants, as
described below.
 
    CLASS B COMMON STOCK.  In conjunction with the Eldorado Acquisition
financing, the 9,697,430 shares of Company common stock, $.01 par value per
share, outstanding immediately prior to the closing of the Eldorado Acquisition
were redesignated as "Class B Common Stock," and the Company issued 4,248,431
additional shares of Class B Common Stock to various accredited investors for
consideration, net of a 1% commitment fee, of $17,735,115.
 
    DCG, the Company's largest shareholder, purchased 1,012,244 of those shares
of Class B Common Stock for aggregate consideration, net of a 1% commitment fee,
of $4,419,793, of which $4.3 million initially was made in the form of a loan to
the Company in December 1996 to fund an escrow account that would have been
forfeited to Eldorado if the Company were unable to consummate the Acquisition
financing. Peter H. Paulsen, a director of the Company, loaned $200,000 to the
Company on the same terms as DCG. That $4.5 million was converted to shares of
Class B Common Stock upon the consummation of the Acquisition at a purchase
price of $4.40 per share less the 1% commitment fee, which was the same price at
which the remaining shares of common stock and the Special Common Stock were
sold by the Company to fund the acquisition.
 
    SPECIAL COMMON STOCK.  The Company sold a total of 4,825,718 shares of
Special Common Stock, $.01 par value per share (the "Special Common"), to DCG,

    The Special Common Stock will be entitled to a liquidation preference over
the Class B Common Stock if, in the case of a liquidation or a change in control
of the Company the distribution per share of Common Stock is less than $4.81.
With the exception of 927,826 shares of Non-Voting Special Common Stock issued
to each of MDP and Olympus, the Special Common Stock will have one vote per

Preferred Stock, each of MDP, Olympus and DCG purchased a common stock warrant
(collectively, the "Investor Warrants") that entitles the holder to purchase
shares of Class B Common Stock at an exercise price of $4.81 per share. An
aggregate of 4,000,000 shares of Class B Common Stock are subject to the
Investor Warrants. The Investor Warrants expire on June 6, 2007. The aggregate
purchase price of the Investor Warrants was $40,000.
 
    The Company also issued common stock warrants (collectively, the "Shattan
Warrants") to The Shattan Group, LLC (and certain affiliates), which acted as
the Company's placement agent for the sale of securities to MDP and Olympus. The
Shattan Warrants, which were issued as of June 6, 1997 and July 15, 1997,
respectively, entitle the holders thereof to purchase an aggregate of 482,433
shares of Class B Common Stock at an exercise price of $4.81 per share and
expire on June 6, 2002 and July 15, 2002, respectively. The aggregate purchase

assumed discount rate of 6.00% for the year ended December 31, 1998 and 7.00%
for the year ended December 31, 1997. The benefit obligation is paid using
Company assets upon the executive officers' death or retirement.
 
RESTRICTED STOCK PLAN
 
    During 1997, the Company's shareholders approved the adoption of a
Restricted Stock Plan, providing for the issuance of common stock to the
Company's current president, subject to restrictions on sale or transfer. The
restrictions on sale or transfer expire over a period of four years which
coincides with the president's retirement. Under this plan 213,778 restricted
shares were issued with a market value of $2,012,000. This amount was recorded
as unearned compensation and is shown as a separate component of shareholders'
equity. Unearned compensation is being amortized to expense over the four year
vesting period with expense of $503,000, and $503,000 recorded for 1998 and
1997, respectively.
 
    Whenever, during the term of employment of the Company's current president,
the Company issues common stock or a common stock equivalent, the Company's
president will be entitled to receive additional shares of restricted stock. The
number of shares of restricted stock that will be issued to the Company's
president will be equal to 3% of the sum of (x) the number of shares of common
stock then to be issued by the Company or, in the case of the issuance of a
common stock equivalent, the number of shares of common stock that such common
stock equivalent may be converted into or exchanged for, and (y) the number of
shares of restricted stock to be issued to the Company's president at that time.
 
STOCK OPTION PLAN
 
    In January 1997, the Company adopted the Option Plan pursuant to which the
Company's Board of Directors or the Compensation Committee (the "Committee") may
grant stock options to directors and certain officers of the Company or any of
its subsidiaries. There are currently 728,600 shares of Class B Common Stock
subject to the Option Plan. The Option Plan provides only for the issuance of
so-called

"nonqualified" stock options (as compared to incentive stock options). The
options granted will vest over four years, in half-year increments, with the
first portion vesting on the 18-month anniversary of the date of grant. The
Option Plan provides that unless the Committee otherwise determines, the options
will have a six-year term, expiring on the sixth anniversary of the date of
grant.

    At December 31, 1998 29,959 shares were exercisable at prices ranging from
$9.64 to $10.52 per share. These shares had a weighted average remaining
contractual life of 4 years and a weighted average exercise price of $9.76.
 
    The maximum number of shares as to which options may be granted under the
Option Plan is sometimes referred to as the "Option Pool." Until such time as
the Company has Tier 1 Capital of $125.0 million or more, if the Company issues
any additional common stock or common stock equivalents, the number of shares in
the Option Pool automatically increases such that the number of shares in the
Option Pool will be equal to 6% of the sum of (i) the shares of common stock
(and common stock equivalents) issued and outstanding immediately following such
issuance and (ii) the number of shares in the Option Pool. The Company had Tier
1 capital of $79.6 million at December 31, 1998.
 
    The Company applies APB Opinion 25 in accounting for its Options Plan, and
accordingly, no compensation cost has been recognized for its stock options in
the consolidated financial statements. Had the Company determined compensation
cost based on the fair value at the grant date for its stock options under the
methodology prescribed under SFAS 123, the Company's net earnings and earnings
per share for 1998 and 1997 would have been reduced to the pro forma amounts
indicated below. The per share weighted-average fair value of the stock options
granted during 1998 and 1997 was $3.36 and $2.46, respectively. The fair value
of each option grant is estimated on the date of grant using the Black-Scholes

NOTE 14--CAPITAL ADEQUACY:
 
    The Bank is subject to various regulatory capital requirements established
by the federal banking agencies. Failure to meet minimum capital requirements
can initiate certain mandatory and possibly additional discretionary actions by
regulators that, if undertaken, could have a direct material effect on the
Bank's financial statements. Under capital adequacy guidelines and the
regulatory framework for prompt corrective action, the Bank must meet specific
capital guidelines that involve quantitative measures of the Bank's assets,
liabilities and certain off-balance sheet items as calculated under regulatory
accounting practices. The Bank's capital amounts and classifications are also
subject to qualitative judgment by the regulators about components, risk
weighting, and other factors.
 
    Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum amounts and ratios (set forth in the table
below) of total and Tier 1 capital (as defined in the regulations) to
risk-weighted assets (as defined), and of Tier I capital (as defined) to average
assets (as defined). Management believes, as of December 31, 1998, that the Bank
meets all capital adequacy requirements to which it is subject.
 
    As of December 31, 1998, the most recent notification from the Department of
Financial Institutions (DFI) categorized the Bank as adequately capitalized
under the regulatory framework for prompt corrective action. To be categorized
as adequately capitalized the Bank must maintain minimum total risk-based, Tier
1 risk-based, and Tier 1 leverage ratios as set forth in the table. There are no
conditions or events since that notification that management believes have
changed the Bank's category.

NOTE 15--FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK:
 
    In the ordinary course of business, the Company enters into various types of
transactions which involve financial instruments with off-balance sheet risk.
These financial instruments include commitments to extend credit and sell loans,
standby letters of credit, forward commitments to sell mortgage-backed
securities and put options to sell mortgage-backed securities and are not
reflected in the accompanying consolidated statement of financial condition.
These financial instruments carry various degrees of credit and market risk.
Credit risk is defined as the possibility that a loss may occur from the failure
of another party to perform according to the terms of the contract. Market risk
is the possibility that future changes in market prices will make a financial
instrument less valuable. Management does not anticipate that the settlement of
these financial instruments will have a material adverse effect on the Company's
financial position or results of operations.
 
    The contract or notional amounts of those instruments reflect the extent of
the Company's involvement in particular classes of financial instruments. The
following is a summary of the notional amounts of various off-balance sheet
financial instruments entered into by the Company:

NOTE 15--FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK: (CONTINUED)
funded through short-term demand deposits and certificates of deposit with fixed
rates. The contractual amounts of commitments to extend credit, standby and
commercial letters of credit represent the amount of credit risk. Since many of
the commitments and letters of credit are expected to expire without being
drawn, the contractual amounts do not necessarily represent future cash
requirements.
 
    Commitments to extend credit are agreements to lend to a customer as long as
there are no violations of any conditions established in the contract. The
Company evaluates the creditworthiness of each customer. The amount of
collateral obtained, if deemed necessary by the Company upon the extension of
credit, is based upon management's evaluation. Collateral varies, but may
include securities, accounts receivable, inventory, personal property,
equipment, income property, commercial and residential property. Commitments
generally have fixed expiration dates or other terminal clauses and may require
the payment of fees. The Company experiences interest rate risk on commitments
to extend credit which are at fixed rates. There were no fixed rate commitments
at December 31, 1998 or 1997.
 
    Standby letters of credit are written conditional commitments issued by the
Company to guarantee the performance of a customer to a third party, generally
in the production of goods and services or under contractual commitments in the
financial market. The credit risk involved in issuing letters of credit is
essentially the same as that involved in extending loan facilities to customers.
The Bank uses the same underwriting policies as if a loan were made.
 
    The Bank's policy is to hedge a portion of its loans held for sale and its
commitments to originate loans against interest rate risk with forward
commitments to sell, or put options on, mortgage-backed securities. Forward
commitments are contracts for delayed delivery of securities in which the Bank
agrees to make delivery at a specified future date of a specified security, at a
specified price or yield. Put options convey to the Bank the right, but not the
obligation, to sell the securities at a contractually specified price. Risks
arise from the possible inability of counterparties to meet the terms of their
contracts and from movements in securities' values and interest rates. The Bank
tries to minimize these risks by dealing with only primary brokers and
maintaining correlation with the asset or commitment being hedged. The Bank
monitors its exposure through the use of valuation models provided by a
financial advisory service. The unrealized losses on open forward contracts to
sell mortgage-backed securities were $108,000 and $44,000 as of December 31,
1998 and 1997, respectively. There were no unrealized losses on open put options
to sell mortgage-backed securities as of December 31, 1998 and 1997.
 
    Commitments to sell loans are agreements to sell loans originated by the
Bank to investors. These commitments may be optional or mandatory. Under an
optional commitment, a commitment fee is paid and the Bank carries no risk in
excess of the loss of such fee in the event that the Bank is unable to deliver
the loans into the commitment. Mandatory commitments may entail possible
financial risk to the Bank if it is unable to deliver the loans in sufficient
quantity or at sufficient rates for commitments which are at a fixed rate. There
were commitments of $94,000,000 and $26,000,000 at December 31, 1998 and 1997.
At December 31, 1998 the commitments were a combination of fixed and adjustable
rate loans with coupons ranging from 5.5% to 7.00% and with settlement dates
ranging from January 14, 1999 to February 22, 1999. The Bank had closed loans at
December 31, 1998 of $43,287,000 with which to satisfy those commitments and a
pipeline of unclosed loans of $89,732,000 that, in management's opinion, will be
sufficient to fulfill the balance of the commitment.

CASH AND FEDERAL FUNDS SOLD
 
    For cash and Federal funds sold the carrying amount is a reasonable estimate
of fair value.
 
INVESTMENT SECURITIES
 
    All investment securities are marketable and have an easily determined
market value. Market quotes are used in determining the fair value.
 
LOANS AND LEASES RECEIVABLE
 
    Loans were broken into fixed and variable rate loans for this analysis. The
credit risk component of the fair value analysis is assumed to be approximated
by the loan and lease loss reserve. A separate analysis is conducted on the
adequacy for the allowance for loan and lease losses and should be a reasonable
proxy for this credit risk component.
 
    Fixed rate commercial and consumer loans are valued using a discounted cash
flow model that assumes a prepayment rate of 10% and a discount rate of prime
plus 50 basis points. These commercial and consumer loans were grouped into
categories and the weighted average maturity and rate were used in computing the
future cash flows. Leases are regularly sold into the secondary market and on
average have sold at a premium of approximately 3%. To determine the fair value
of leases, this potential sale premium was discounted to par to account for the
delinquent leases that would not garner the same sale premium. Fixed rate
residential mortgage loans were valued at par realizing that any premiums
attributable to the performing portfolio would be offset by discounts in the
delinquent portion of the portfolio.
 
    Variable rate loans were broken down by loan type and evaluated based upon
the current weighted average rate of the loans in comparison to current market
conditions. Premiums of up to 2% were applied to those groups of loans that had
higher than market rates while loans at or below market were discounted.

NOTE 16--DISCLOSURES ABOUT FAIR VALUES OF FINANCIAL INSTRUMENTS: (CONTINUED)
MORTGAGE LOANS HELD FOR SALE
 
    Loans held for sale are valued at a premium of 1%. These loans consist of
residential mortgage loans and are largely a fixed rate product. The premium
used approximates the gain that would be recognized on the sale of these loans,
discounted for hedging and sales costs.
 
DEPOSITS
 
    Deposits consist of both non-interest and interest bearing accounts. Each
type of account has been valued differently as described below.
 
    Non-interest bearing demand--Core non-interest bearing deposits are a
premium account for commercial banks and as such have been valued with a factor
of .95. Non-core type accounts such as title company deposits and custodial
accounts have been valued at par due to their temporary and volatile nature.
 
    Interest bearing demand, savings and money market accounts--These accounts
are all priced competitively in the marketplace and are low cost funds for the
Bank. As such, these deposits have also been ascribed as premium accounts and
valued with a factor of .99.
 
    Certificates of deposit--Certificates of deposit accounts ("CD") were marked
to market utilizing current CD rates compared to rates being paid. CDs were
grouped based upon their remaining maturities and the weighted average maturity
and rates were grouped based upon their remaining maturities and the weighted
average maturity and rates were utilized in the analysis. Current rates for CDs
were determined utilizing the Treasury rates for comparable maturities less 25
basis points.
 
    Generally, rates currently being paid are higher than current market rates
which results in these accounts having a lower fair value.
 
BORROWINGS
 
    Federal funds purchased are over-night investments and the carrying value is
a reasonable estimate of fair value. For subordinated debentures, having been
recently priced at the issuance in 1997, the carrying value is a reasonable
estimate of fair value.
 
NOTE PAYABLE TO RELATED PARTIES
 
    The note payable to related parties has a maturity of 15 months and is
stated at cost.
 
OFF-BALANCE SHEET FINANCIAL INSTRUMENTS
 
    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 counterparties. 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 counterparties at the reporting date. The fair value of commitments to
extend credit and standby letters of credit is not material.

active exchange quotations. The fair value of put options to sell
mortgage-backed securities is not material.

LITIGATION
 
    As of December 31, 1998, no litigation was pending against the Company
itself. Eldorado Bank is the defendant in an action filed in 1994 by a former
CSB loan production officer alleging wrongful termination, breach of contract,
defamation and various other causes of action. In October 1997, a jury awarded
the former employee $3.8 million in damages, including $2.0 million in punitive
damages. The trial court subsequently reduced the award to $2.0 million,
including $500,000 in punitive damages. In conjunction with this initial
judgment, the Bank recorded a reserve for the full amount of the judgment. Both
the Company and its former employee have filed appeals, with the former employee
seeking to have the total amount of the jury's punitive damage award reinstated.
Interest accrues on the judgment at the statutory rate of 10% and as of December
31, 1998 the judgment, including interest, was equal to $2.6 million. There can
be no assurance, however, that the Company will not incur additional expense in
connection with such matter or that an adverse outcome in the appeal will not
have a material adverse effect on the Company's results of operations.
 
    The Company is from time to time subject to various legal actions (in
addition to that described above) which are considered to be part of its normal
course of business. Management, after consultation with legal counsel, does not
believe that the ultimate liability, if any, arising from those other actions
will have a materially adverse effect on the financial position or results of
operations of the Company.

31, 1998 is as follows:

NOTE 17--COMMITMENTS AND CONTINGENCIES: (CONTINUED)
DIVIDEND RESTRICTIONS
 
    Federal Reserve policies declare that a bank holding company may not pay
cash dividends on its common stock unless its net income is sufficient to fund
fully such dividend, and its prospective rate of earnings retention after the
payment of such dividend appears consistent with its capital needs, asset
quality and overall financial condition. In connection with the Eldorado
Acquisition, the Company agreed that it will not pay dividends on common stock
without the prior approval of the Federal Reserve.
 
    The Company is a legal entity separate and distinct from the Bank.
Substantially all of the Company's revenues and cash flow, including funds
available for the payments of dividends and other operating expenses, consists
of dividends paid to the Company by the Bank. There are statutory and regulatory
limitations on the amount of dividends which may be paid to the Company by the
Bank. Dividends payable by the Bank are restricted under California law to the
lesser of the Bank's retained earnings, or the Bank's net income for the latest
three fiscal years, less dividends previously declared during that period, or,
with the approval of the DFI, to the greater of the retained earnings of the
Bank, the net income of the Bank for its last fiscal year or the net income of
the Bank for its current fiscal year. In connection with the Eldorado
Acquisition, Eldorado Bank paid a dividend of $14 million, which exceeded the
Bank's net income for the previous three fiscal years. As a result, the Bank
must obtain the approval of the DFI with respect to the payment of any dividend
up to the greater of the Bank's retained earnings, the net income of the Bank
for its last fiscal year and the net income of the Bank for its current fiscal
year. In no event can the Bank issue a dividend in excess of such amounts.
 
    Federal Reserve regulations also limit the payment of dividends by a state
member bank. Under Federal Reserve regulations, dividends may not be paid unless
both undivided profits and earnings limitations have been met. First, no
dividend may be paid if it would result in a withdrawal of capital or exceed the
bank's undivided profits as reported in its most recent Report of Condition and
Income, without the prior approval of the Federal Reserve and two-thirds of the
shareholders of each class of stock outstanding. Second, a state member bank may
not pay a dividend without the prior written approval of the Federal Reserve if
the total of all dividends declared in one year exceeds the total of net income
for that year plus its retained net income for the preceding two calendar years.
 
    The payment of dividends on capital stock by the Company and the Bank may
also be limited by other factors, including applicable regulatory capital
requirements and broad enforcement powers of the federal regulatory agencies.
Both the Federal Reserve and the DFI have broad authority to prohibit the
Company and the Bank from engaging in practices which the banking agency
considers to be unsafe or unsound. It is possible, depending upon the financial
condition of the Bank or the Company and other factors, that the applicable
regulator may assert that the payment of dividends or other payments by the Bank
or the Company is an unsafe or unsound practice and, therefore, implement
corrective action to address such a practice. Among other things, Federal
Reserve 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 and tax sharing payments which do not
reflect the taxes actually due and payable.
 
    The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
generally prohibits a depository institution from making any capital
distribution (including payment of a dividend) or paying any management fee to
its holding company if the depository institution would thereafter be
"undercapitalized" for regulatory purposes. Those regulations and restrictions
may limit the Company's

NOTE 18--OPERATING SEGMENTS:
 
    The Company has determined that its reportable segments are the operations
pertaining to mortgage banking ("Mortgage") and the operations pertaining to
commercial and consumer banking ("Commercial and Consumer"). Commercial and
Consumer includes the operations of the Company's equipment leasing division.
The segment labeled "Other" primarily consists of the Company's administrative
function which is responsible for investment and borrowing activities and other
administrative services. The financial results of the Company's operating
segments are presented on an accrual basis. There are no significant differences
among the accounting policies of the segments as compared to the Company's
consolidated financial statements. The Company evaluates the performance of its
segments based on net interest income, non-interest income, net income and total
assets. Funds are allocated as needed from Commercial Banking to Mortgage at a
rate comparable to the prime rate less 2.25%.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                        DECEMBER 31, 1998, 1997 AND 1996
 
NOTE 20--SUBSEQUENT EVENTS:
 
    Effective January 22, 1999, the Company completed the acquisition of
Antelope Valley Bank ("Antelope"). The acquisition of Antelope was effected
pursuant to an Agreement and Plan of Merger entered into between the Company and
Antelope on September 22, 1998 (the "Acquisition Agreement"). At December 31,
1998, Antelope had assets of $211,700,000, deposits of $187,749,000 and
shareholders' equity of $21,393,000. The Company issued 2,777,543 shares of
Class B common stock to complete the merger with Antelope.
 
    The Antelope Acquisition was accounted for using the pooling of interest
method of accounting in accordance with APB Opinion 16, "Business Combinations."
Accordingly, the assets, liabilities and shareholders' equity of Antelope will
be recorded on the books of the Company at their values as reported on the books
of Antelope immediately prior to the consummation of the merger. No goodwill
will be created in the merger with Antelope.
 
    The following table sets forth selected pro forma combined financial
information of the Company and Antelope for the years ended December 31, 1998
and 1997. The pro forma operating data reflects the effect of the Antelope
Acquisition as if it was consummated on January 1, 1997. The pro forma results
are not necessarily indicative of the results that would have occurred had the
acquisition actually occurred as of such date, nor are they necessarily
indicative of the results of future operations.
