Dear Shareholders:

         You are cordially invited to attend a Special Meeting of Shareholders
of Eldorado Bancorp ("Eldorado" or the "Company") to be held at the Sutton Place
Hotel, located at 4500 MacArthur Boulevard, Newport Beach, California, at 10:00
a.m. local time on Wednesday, April 30, 1997.

         At the Special Meeting, you will be asked to consider and vote upon a
proposal to approve the principal terms of the Agreement and Plan of Merger,
dated as of December 24, 1996 (the "Merger Agreement"), by and between Eldorado
and Commerce Security Bancorp, Inc., a Delaware corporation ("CSBI"), pursuant
to which CSBI will acquire Eldorado by means of a cash merger (the "Merger").
Under the terms of the Merger Agreement, each share of Eldorado's common stock,
no par value (the "Common Stock"), outstanding at the time that the Merger
becomes effective (the "Effective Time") (other than certain shares held by CSBI
and shares for which dissenters' rights have been perfected) will be converted
into the right to receive cash in the amount $23.00, without interest.

         The proposed Merger requires certain regulatory approvals and the
approval of the principal terms of the Merger Agreement by the holders of a
majority of the outstanding shares of Common Stock of Eldorado, in addition to
the satisfaction of other conditions. Shareholders who comply with certain
requirements (described in the Proxy Statement under "THE MERGER AGREEMENT AND
THE MERGER -- Dissenters' Rights" and in Appendix D to the Proxy Statement) may
be entitled to dissenters' rights with respect to their shares, but only if
holders of more than five percent of the outstanding shares of Common Stock
exercise such rights. More detailed information about the Merger Agreement and
other matters regarding the Merger and the Special Meeting are included in the
accompanying Proxy Statement. You are urged to carefully review the Proxy
Statement. 

         After careful consideration, your Board of Directors has unanimously
approved the Merger and unanimously recommends that you vote FOR the approval of
the principal terms of the Merger Agreement and the transactions contemplated
thereby.

         It is important that your shares be represented and voted at this
Special Meeting. Whether or not you currently plan to attend the Special
Meeting, please complete, sign, date and return the enclosed proxy card in the
postage-paid envelope as soon as possible. If you hold shares in more than one
name, or if your shares are registered in more than one way, you may receive
more than one copy of the proxy materials. So, please complete, sign, date and
return each of the proxy cards you receive so that all of your shares may be
voted. If you attend the Special Meeting and vote in person, your vote will
supersede your proxy.

         I look forward to seeing you at the Special Meeting.

                                Sincerely,


                                J.  B. Crowell

         1.       To approve the principal terms of an Agreement and Plan of
                  Merger, dated as of December 24, 1996 (the "Merger
                  Agreement"), by and among Eldorado and Commerce Security
                  Bancorp, Inc., a Delaware corporation ("CSBI"), pursuant to
                  which, subject to regulatory approvals and certain other
                  conditions, Eldorado will be acquired by CSBI by means of a
                  merger (the "Merger") of a subsidiary of CSBI with and into
                  Eldorado, with Eldorado continuing as the surviving
                  corporation. If the Merger is approved and consummated, each
                  outstanding share of Eldorado's common stock, no par value
                  (the "Common Stock") (other than certain shares held by CSBI
                  and shares as to which dissenters' rights are perfected) will

         2.       To transact such other business as may properly come before

         Only shareholders of record at the close of business on Monday, March
3, 1997, are entitled to notice of, and to vote at, the Special Meeting or any
adjournments or postponements thereof. Each share of Common Stock will entitle
the holder to one vote at the Special Meeting.

         The affirmative vote of the holders of a majority of the outstanding
shares of Common Stock is necessary to approve the principal terms of the Merger
Agreement. All shareholders, whether or not they expect to attend the meeting in
person, are requested to complete, sign, date and return the enclosed form of
proxy in the accompanying envelope (which requires no additional postage if
mailed in the United States). Your proxy will be revocable by filing with the
Secretary a written revocation or a proxy bearing a later date at any time prior
to the time it is voted, or by attending the Special Meeting and voting in
person. Unless otherwise instructed, each valid proxy returned that is not
revoked will be voted FOR approval of the principal terms of the Merger
Agreement.

                                     By Order of the Board of Directors,



                                     Elaine P. Crouch

THE PARTIES

         Eldorado. Eldorado, a bank holding company registered under the Bank

THE SPECIAL MEETING

         The Special Meeting will be held at the Sutton Place Hotel, located at
4500 MacArthur Boulevard, Newport Beach, California on Wednesday, April 30,
1997, at 10:00 a.m. local time. The purposes of the Special Meeting are to
consider and vote upon a proposal to approve the principal terms of the Merger
Agreement and the Merger, and such other business as may properly come before
the Special Meeting. If the Merger is approved and the Merger is consummated,
each outstanding share of Common Stock (other than certain shares held by CSBI
and shares as to which dissenters' rights are perfected) will be converted into
the right to receive cash in the amount of $23.00, without interest.

SHAREHOLDERS ENTITLED TO VOTE; VOTE REQUIRED

         The Board of Directors has fixed the close of business on March 3, 1997
as the record date (the "Record Date") for determining those shareholders
entitled to notice of, and to vote at, the Special Meeting. As of the Record
Date, there were 3,811,746 shares of Common Stock outstanding, of which 928,832
shares (approximately 23.4%) were beneficially owned

                                       1
<PAGE>   8
by directors and executive officers of Eldorado and their affiliates. The
affirmative vote of the holders of a majority of the outstanding shares of
Common Stock is required for the approval of the Merger Agreement and the
Merger.

REASONS FOR THE MERGER AND RECOMMENDATIONS OF THE BOARD OF DIRECTORS

         The Board of Directors of Eldorado has unanimously approved the Merger
Agreement and determined that the Merger is fair to, and in the best interests
of, Eldorado's shareholders. In making this determination, the Board of
Directors considered a number of factors, including Eldorado's business and
prospects, conditions in its marketplace, the effects of the consolidation of
financial institutions generally, the comparative value of pursuing other
potential merger transactions and the opinion of its financial advisor. THE
BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE ELDORADO SHAREHOLDERS VOTE
"FOR" APPROVAL OF THE MERGER AGREEMENT AND THE MERGER. See "THE MERGER AGREEMENT
AND THE MERGER -- Background and Reasons for the Merger" and " -- Recommendation
of the Board of Directors." 

OPINION OF FINANCIAL ADVISOR

         Alex Sheshunoff & Co. Investment Banking ("Sheshunoff"), Eldorado's
financial advisor, has delivered its written opinion to the Board of Directors
of Eldorado that, as of December 21, 1996, the consideration to be received in
the Merger by the holders of Common Stock is fair, from a financial point of
view, to the shareholders of Eldorado. The full text of the opinion of
Sheshunoff, which sets forth the assumptions made, matters considered and
limitations on the review undertaken by Sheshunoff, is attached as Appendix C to
this Proxy Statement. Eldorado shareholders are urged to read the opinion in its
entirety. See "THE MERGER AGREEMENT AND THE MERGER -- Opinion of Financial
Advisor."

REGULATORY APPROVALS REQUIRED

         The transactions contemplated by the Merger Agreement are subject to
prior approval by the Board of Governors of the Federal Reserve System ("FRB")
and the State of California's Superintendent of Banks. CSBI has informed
Eldorado that CSBI has filed a draft application with the FRB on February 19,
1997, an application with the California Superintendent of Banks on February 27,
1997, and has further informed Eldorado that it intends to submit a final
application seeking approval of the Merger with the FRB in March 1997. If
approved by the FRB, the proposed Merger must be submitted to the U.S.
Department of Justice for a determination as to whether the Merger will have any
anti-competitive effects. There can be no assurance that any of these regulatory
authorities will approve the Merger, or if approved, as to the date of such
approvals. There can also be no assurances that such approvals will not contain
requirements or conditions which will cause such approvals to fail to satisfy
the conditions to the consummation of the Merger. See "THE MERGER AGREEMENT AND
THE MERGER -- Regulatory Approvals Required."

INTERESTS OF CERTAIN PERSONS IN THE MERGER

         Eldorado's directors and executive officers who own Common Stock will
receive the same price per share as all other shareholders, and will become
entitled to receive a cash payment as consideration for the cancellation of
options to purchase Common Stock on the same terms and conditions as all other
optionholders. Although no written agreement has been executed, it is
anticipated that substantially all of the officers and staff of Eldorado Bank
will be retained after the Merger is consummated. See "THE MERGER AGREEMENT AND
THE MERGER -- Interests of Certain Persons in the Merger."

AGREEMENTS WITH CERTAIN SHAREHOLDERS

         On the same day it entered into the Merger Agreement, December 24,
1996, CSBI entered into a Voting Agreement with each of the members of the
Eldorado Board of Directors, as well as one of Eldorado's officers, in their
capacities as shareholders of Eldorado. Each of the persons who executed a
Voting Agreement agreed to vote the number of shares of Common Stock owned by
them in favor of the Merger Agreement and the Merger. The number of shares of

                                       2
<PAGE>   9
Common Stock covered by the Voting Agreements is 766,389, which constitutes
approximately 20.1% of the number of outstanding shares of Common Stock. See
"THE SPECIAL MEETING -- Agreements with Certain Shareholders."

CONDITIONS TO THE MERGER; TERMINATION

         The obligations of the parties to the Merger Agreement to consummate
the Merger are subject to a number of conditions, including the obtaining of all
required regulatory approvals, approval by Eldorado's shareholders, favorable
legal opinions and the absence of material adverse changes in the financial
condition, results of operations and prospects of Eldorado. See "THE MERGER
AGREEMENT AND THE MERGER -- Conditions to the Merger." The Merger Agreement may
be terminated at any time prior to the Effective Time by mutual consent of
Eldorado and CSBI, or by either party unilaterally in the event of a material
breach of the Merger Agreement by the other party or if the Merger is not
consummated prior to August 1, 1997. See "THE MERGER AGREEMENT AND THE MERGER --
Termination of the Merger Agreement."

NO SOLICITATION OF ACQUISITION PROPOSALS

           Under the Merger Agreement, each party has agreed to take certain
actions and to refrain from taking certain other actions prior to the Effective
Time. In addition, Eldorado has agreed not to solicit any proposal from any
third party relating to a sale of all or a substantial interest in Eldorado or
similar transaction, and not to respond to any such proposal from a third party
unless the Board of Directors has determined, in accordance with certain
procedures, that it is legally obligated to so respond. If Eldorado receives an
offer from a third party providing for the sale of all or a substantial interest
in Eldorado or a similar transaction which meets certain conditions, then
Eldorado may terminate the Merger Agreement. In addition, if Eldorado fails to
reaffirm its intent to proceed with the Merger after receipt of such an offer
from a third party, then CSBI may terminate the Merger Agreement. Under either
of the foregoing circumstances, Eldorado will be required to pay a termination
fee, which consists of the payment by Eldorado of a cash fee, and an option to
purchase shares of Common Stock previously issued to CSBI will become
immediately exercisable. Such cash payment and stock option are collectively
referred to as the "Termination Fee." Such termination fee is also triggered if
the Board of Directors fails to give or withdraws its recommendation of approval
of the Merger Agreement and the Merger. See "THE MERGER AGREEMENT AND THE MERGER
- -- Termination of the Merger Agreement" and "-- The Stock Option Agreement." 

SURRENDER OF CERTIFICATES

           If the Merger is approved and becomes effective, Eldorado will mail a
letter of transmittal with instructions to all holders of record of Common Stock
as of the Effective Time for use in surrendering their stock certificates in
exchange for cash as provided in the Merger Agreement. STOCK CERTIFICATES SHOULD
NOT BE SURRENDERED UNTIL THE LETTER OF TRANSMITTAL IS RECEIVED. See "THE MERGER
AGREEMENT AND THE MERGER -- How to Surrender and Receive Payment for Shares."

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         The Merger will generally represent a taxable transaction to Eldorado's
shareholders, who generally will realize taxable gain or loss measured by the
difference between the shareholders' adjusted tax bases for their shares and the
amounts received as a result of the Merger. See "THE MERGER AGREEMENT AND THE
MERGER -- Federal Income Tax Consequences of the Merger."

DISSENTERS' RIGHTS

         Under Chapter 13 of the California General Corporation Law ("Chapter
13"), the full text of which is attached to this Proxy Statement as Appendix D,
holders of record of Common Stock are entitled to dissenters' rights in
connection with the Merger. If the Merger is approved by the shareholders and
consummated, any shareholder, subject to compliance with certain procedures, has
rights as a dissenting shareholder to have its shares purchased at fair market
value. Shareholders wishing to exercise their dissenters' rights must deliver
written demand for the purchase of their shares before the Special Meeting and
vote against the Merger. Under the provisions of Chapter 13, shares of Common
Stock are not eligible to be treated as dissenting shares unless demands for
payment are filed with respect to five percent or more of the outstanding Common
Stock. Any shareholder who institutes legal action to attack the validity of the
Merger or to have the Merger set aside or rescinded may not later exercise
dissenters' rights. The amount of cash to which any shareholder who perfects its
dissenters' rights may become entitled to receive may be more or less than the
amount of cash provided in the Merger Agreement. The required procedures must be
followed exactly or dissenters' rights, if available, may be lost. For a summary
of these rights see "THE MERGER AGREEMENT AND THE MERGER -- Dissenters' Rights."

                               THE SPECIAL MEETING

         This Proxy Statement is being furnished to shareholders of Eldorado in
connection with the solicitation of proxies by the Board of Directors of
Eldorado for use at the Special Meeting. At the Special Meeting, shareholders of
Eldorado will be asked to consider and vote upon a proposal to approve the
principal terms of the Merger Agreement and the Merger.

DATE, PLACE AND TIME

         The Special Meeting will be held at the Sutton Place Hotel, located at
4500 MacArthur Boulevard in the City of Newport Beach, California, on
Wednesday, April 30, 1997, at 10:00 a.m. local time.

RECORD DATE AND VOTING RIGHTS

         The Board of Directors of Eldorado has fixed March 3, 1997, as the
record date (the "Record Date") for the determination of shareholders entitled
to notice of and to vote at the Special Meeting. As of the Record Date, there
were 3,811,746 shares of Common Stock outstanding, held by approximately 910
holders of record. Each holder of record of shares of Common Stock on the Record
Date is entitled to cast one vote per share, in person or by proxy, at the
Special Meeting.

         As of March 3, 1997, directors and executive officers of Eldorado and
their affiliates had the right to vote 928,832 shares, or approximately 23.4% of
the outstanding shares of Common Stock, including an aggregate of 159,369 shares
that the directors, executive officers and their respective affiliates had the
right to acquire within 60 days after March 3, 1996, through the exercise of
stock options. The directors and executive officers of Eldorado have indicated
that they intend to vote their shares of Common Stock "FOR" approval of the
Merger Agreement. See "-- Agreements with Certain Shareholders" and "SECURITY
OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT."

QUORUM AND VOTING OF PROXIES

         The presence, in person or by proxy, of a majority of the outstanding
shares of Common Stock is necessary to constitute a quorum at the Special
Meeting. Shareholders voting or abstaining from voting on any issue will be
counted as present for purposes of constituting a quorum. Under the rules of the
AMEX, brokers who hold shares in street name for customers will not have
authority to vote such shares on the proposal to approve the Merger Agreement
unless they have received written instructions from beneficial owners. Because
the affirmative vote of a majority of the outstanding shares of Common Stock of
Eldorado is required to approve the Merger, shares not voted on the proposal and
abstentions will have the same effect as votes against the proposal.

         All shares which are entitled to vote and are represented at the
Special Meeting by properly executed proxies received prior to or at the Special
Meeting, and not revoked, will be voted at the Special Meeting in accordance
with the instructions indicated on such proxies. IF NO INSTRUCTIONS ARE
INDICATED, SUCH PROXIES WILL BE VOTED FOR APPROVAL OF THE MERGER AGREEMENT AND
THE MERGER. The Board of Directors of Eldorado knows of no matters to be
presented at the Special Meeting other than those described in this Proxy
Statement. If any other matters are properly presented at the Special Meeting
for consideration, including, among other things, consideration of a motion to
adjourn the Special Meeting to another time and/or place (including, without
limitation, for the purpose of soliciting additional proxies), the persons
appointed as proxy will have discretion to vote on such matters in accordance
with their best judgment, except that shares represented by proxies which have
been voted "AGAINST" approval of the Merger Agreement and the Merger will not be
voted in respect of any motion made for adjournment of the Special Meeting for
purposes of soliciting additional votes to approve the Merger Agreement and the
Merger.

         Any proxy given pursuant to this solicitation may be revoked by the
person giving it at any time before it is voted. Proxies may be revoked or
superseded by: (i) filing a written notice of revocation bearing a later date
than the proxy with the Secretary of Eldorado (Elaine P. Crouch) at or before
the taking of the vote at the Special Meeting; (ii) duly executing a later dated
proxy relating to the same shares and delivering it to the Secretary of Eldorado
(Elaine P. Crouch) before the

                                       5
<PAGE>   12
taking of the vote at the Special Meeting; or (iii) attending the Special
Meeting and voting in person (although attendance at the Special Meeting will
not in and of itself constitute a revocation of a proxy).

         All expenses of this solicitation, including the cost of preparing and
mailing this Proxy Statement, will be borne by Eldorado. In addition to
solicitation by use of the mails, proxies may be solicited by directors,
officers and employees of Eldorado in person or by telephone, telegram,
facsimile transmission or other means of communication. Such directors, officers
and employees will not be additionally compensated, but may be reimbursed for
reasonable out-of-pocket expenses in connection with such solicitation.
Arrangements will also be made with custodians, nominees and fiduciaries for
forwarding of proxy solicitation materials to beneficial owners of shares held
of record by such custodians, nominees and fiduciaries, and Eldorado will
reimburse such custodians, nominees and fiduciaries for reasonable expenses
incurred in connection therewith. Eldorado also has retained ChaseMellon
Shareholder Services LLC to assist it in distributing the Proxy Statement to and
soliciting proxies from shareholders. The fee paid by Eldorado for such services
will be approximately $4,000, plus reimbursement of out-of-pocket costs.

SHAREHOLDER VOTE REQUIRED

         Under the California General Corporation Law, the approval of the
Merger requires the affirmative vote of the holders of a majority of the
outstanding shares of Common Stock.

DISSENTERS' RIGHTS

         If the Merger is approved and consummated, dissenters' rights will be
available to holders of Common Stock who exercise such rights in accordance with
Chapter 13 of the California General Corporation Law. THE REQUIRED PROCEDURE SET
FORTH IN CHAPTER 13 MUST BE FOLLOWED EXACTLY OR ANY DISSENTERS' RIGHTS MAY BE
LOST. In order to be entitled to exercise dissenters' rights, a shareholder of
Eldorado must vote "AGAINST" the Merger Agreement. Thus, any shareholder who
wishes to dissent and executes and returns a proxy in the accompanying form must
specify that his or her shares are to be voted "AGAINST" the proposal to approve
the Merger Agreement. Any shareholder who returns a proxy without voting
instructions or with instructions to vote "FOR" or to "ABSTAIN" on the proposal
to approve the Merger Agreement will not be entitled to exercise dissenters'
rights.

         A shareholder of Eldorado electing to exercise dissenters' rights must
also make written demand upon Eldorado for the purchase of dissenting shares and
payment to such shareholder in cash of their fair market value. Such demand must
be received by Eldorado or Eldorado's transfer agent on or prior to the date of
the Special Meeting. The demand should specify the number of shares held of
record by such shareholder which the shareholder demands to be purchased and a
statement of what the shareholder claims to be the fair market value of those
shares as of December 23, 1996. In order for any shareholder to be able exercise
dissenters' rights, holders of five percent or more of the outstanding shares of
Common Stock must have properly and timely made demands for purchase. See "THE
MERGER AGREEMENT AND THE MERGER -- Dissenters' Rights."

                       THE MERGER AGREEMENT AND THE MERGER

         The following description of certain aspects of the Merger Agreement
and the Merger is a summary of the material terms and provisions of the Merger
Agreement, and is qualified in its entirety by reference to the Merger
Agreement, a copy of which is attached to this Proxy Statement as Appendix A and
incorporated herein by reference. ALL SHAREHOLDERS ARE URGED TO CAREFULLY READ
THE MERGER AGREEMENT PRIOR TO VOTING ON THIS PROPOSAL.

GENERAL

         The Merger Agreement provides for the acquisition of Eldorado by CSBI
by means of a cash merger. Upon the consummation of the Merger, each share of
Eldorado Common Stock issued and outstanding immediately prior to the Effective
Time, other than shares for which dissenter's rights are perfected and certain
shares held directly or indirectly by CSBI (which will be canceled), will be
automatically converted into the right to receive $23.00 per share in cash (the
"Merger Consideration"), and the holders of such shares will thereafter cease to
be shareholders of Eldorado and will have no further continuing interest in
Eldorado.

         The completion of the Merger is subject to a number of conditions,
including the approval by the holders of at least a majority of the outstanding
shares of Eldorado Common Stock, the receipt of all necessary consents, waivers,
clearances, approvals and authorizations from regulatory or governmental bodies,
the satisfaction or waiver of certain other conditions, including the absence of
judicial or regulatory actions seeking to restrain or prohibit the Merger, the
receipt of standard officers' certificates, legal opinions and accountant's
letters and the absence of any material adverse change in the condition or
business of Eldorado. See "-- Conditions to the Merger" and "-- Regulatory
Approvals Required."

BACKGROUND AND REASONS FOR THE MERGER

         From the inception of Eldorado, its Board of Directors had maintained a
policy of remaining independent and increasing shareholder value through
improved operating results and strategic acquisitions. Since inception, Eldorado
has achieved its growth in large part as a result of a number of strategic
acquisitions. In recent years, however, the Board of Directors has been aware
that there has been a wave of consolidation in the banking industry on both the
national and regional level and a concurrent increase in the competitiveness of
financial institutions in Eldorado's marketplace. As a result, the Board of
Directors decided that this changing environment in the banking industry
required Eldorado to more aggressively expand its base of operations through
strategic acquisitions of other banks or financial institutions. It was felt
that only pursuing an internal growth strategy would not result in the
objectives desired due to, among other reasons, the expected high cost of such
strategy in the highly-competitive Southern California banking market.
Therefore, in early 1995 the Board of Directors reconstituted the Merger and
Acquisition Committee of the Board of Directors. Under the guidance of the
Merger and Acquisition Committee, in May 1995 Eldorado entered into an agreement
for the purchase of Mariners Bancorp.

         In August 1995, the Board restructured the Merger and Acquisition
Committee in order to more aggressively explore and pursue acquisition
opportunities by which Eldorado could expand its base of operations. The
restructured Merger and Acquisition Committee consisted of five independent
directors. In connection with this new acquisition strategy, Eldorado engaged
the services of a financial advisor to assist Eldorado in the process of
identifying and acquiring one or more banking companies with operations in
Southern California. The restructured Merger and Acquisition Committee analyzed
a number of potential acquisitions; however, Eldorado was not able to consummate
any further acquisitions. Among the reasons why acquisitions were not
consummated was that Eldorado found that certain acquisition candidates would
not provide a "fit" with Eldorado which would be necessary to achieve Eldorado's
acquisition objectives, and certain others had contingent risks which Eldorado
was unwilling to accept. With respect to those few qualified acquisition
candidates which met Eldorado's acquisition profile, Eldorado was unable to
negotiate terms which the Merger and Acquisition Committee felt were in the best
interests of Eldorado and its shareholders, including terms as to the valuation
of such candidates relative to Eldorado.

                                       8
<PAGE>   15
         By mid-1996, the Merger and Acquisition Committee had become concerned
about Eldorado's inability to expand its operations through an acquisition
strategy, especially due to the high premiums being commanded by those banking
institutions which Eldorado needed to pursue in order to effectively implement
such strategy. The Committee believed that the premiums being commanded by
financial institutions, combined with the improvement in the Southern California
economy and concurrent increase in the perceived value of Southern California
banking institutions, merited an inquiry into the value which Eldorado could
command if it were to be sold. Therefore, in June 1996 the full Board of
Directors formed a Shareholder Enhancement Committee to explore the range of
premiums for Eldorado's Common Stock which could be obtained in a sale of
Eldorado and report its findings to the Merger and Acquisition Committee. The
Shareholder Enhancement Committee met several times in June and July of 1996
with respect to the selection of a financial advisor which would be able to
provide guidance to the Board of Directors regarding the valuation of Eldorado
as a potential acquisition target, as well as to assist Eldorado should the
decision be made to pursue a possible sale of Eldorado.

         At about the same time, in June 1996, Eldorado received its first
letter from the Dartmouth Partnership, which currently controls CSBI, indicating
the Dartmouth Partnership's interest in acquiring Eldorado in an all-stock
transaction. The Dartmouth Partnership indicated that it wished to use stock in
a potential acquisition in order to account for such acquisition as a "pooling
of interests" transaction, and that it had no desire at that time to engage in
an all-cash transaction due to the high amount of goodwill which would be
incurred in such a transaction. Eldorado's management, with the approval of the
Shareholder Enhancement Committee, indicated to the Dartmouth Partnership that
it would need to provide additional information prior to any serious
consideration of a transaction between Eldorado and the Dartmouth Partnership.

         In July 1996, the Merger and Acquisition Committee met to discuss a
number of acquisition opportunities which were available to Eldorado. Among the
opportunities considered was a new proposal from the Dartmouth Partnership
whereby Eldorado would merge with a bank controlled by the Dartmouth
Partnership, with Eldorado shareholders retaining a majority ownership interest
in the combined holding company, and with Eldorado's management running the
combined banking entity. After a review of these opportunities, assisted by a
financial advisor retained by Eldorado to conduct analyses on certain of the
target institutions, the Merger and Acquisition Committee concluded, among other
things, that the Dartmouth Partnership proposal would not be in the best
interest of Eldorado, as the proposed relative valuations between the entities
would not be favorable to Eldorado's shareholders. The Merger and Acquisition
Committee also concluded that, because the Shareholder Enhancement Committee was
in the process of selecting a financial advisor to recommend to the Merger and
Acquisition Committee for retention by Eldorado, it would not be in the best
interest of Eldorado to press ahead with any action on potential acquisitions of
other institutions until such time as a financial advisor was retained, as there
was concern that the acquisition by Eldorado of another financial institution
could jeopardize a possible sale of Eldorado. Therefore, the Committee decided
to postpone any decision with respect to any potential acquisition.

         On July 29, 1996, the Shareholder Enhancement Committee recommended to
the Merger and Acquisition Committee, based upon a selection process which
involved presentations from a number of candidates, that Eldorado retain Alex
Sheshunoff & Co. Investment Banking ("Sheshunoff") as a financial advisor for
the purpose of soliciting interest in the possible acquisition of Eldorado and
to manage the process of developing a suitable proposal for such sale. The Board
of Directors subsequently approved the selection of Sheshunoff and Sheshunoff
was retained by Eldorado as its financial advisor on August 1, 1996. In
connection with the solicitation of potential interest in Eldorado, Sheshunoff
prepared an information memorandum on Eldorado and, with Eldorado's consent,
contacted 58 financial institutions in September 1996 to determine the level of
interest in acquiring Eldorado. Of the 58 institutions contacted by Sheshunoff,
18 indicated interest in a potential acquisition of Eldorado and, after signing
confidentiality agreements, each was sent a copy of the information memorandum.
Of the 18 financial institutions which received an information memorandum, four
institutions, including CSBI, submitted preliminary proposals for a potential
acquisition of Eldorado.

         On October 8, 1996, the Merger and Acquisition Committee met with
Eldorado's legal counsel and a representative from Sheshunoff to review the four
preliminary proposals. The preliminary proposals included a proposal from CSBI
in which the aggregate price to be paid in shares of CSBI's stock for Eldorado
was estimated to be approximately $79.2 million (or approximately $21 per
share). However, the stock of CSBI is not traded in a public market and
therefore the value of such shares was not readily ascertainable. Two other
proposals provided for an all-stock transaction (in shares of stock which were
not actively traded, and for which the value was therefore not readily

                                       9
<PAGE>   16
ascertainable) at $21 per share (for an approximate aggregate price of $79.2
million) and an all-cash transaction ranging from $19- $21 per share (for an
approximate aggregate price range of $72.0 million to $79.2 million). The fourth
proposal was for a combined cash and stock transaction, in which the aggregate
price to be paid for Eldorado was between $58 million and $67 million (or an
approximate range of $15 to $18 per share). After extensive discussion of the
relative merits of the four preliminary offers presented, the Merger and
Acquisition Committee determined, based on advice from Sheshunoff, that the
fourth proposal was inadequate and would have to be increased before Eldorado
would permit the institution making such proposal to undertake a due diligence
investigation of Eldorado. The Committee also decided that the other three
bidders would be permitted to conduct due diligence at Eldorado's offices.

         On October 15, 1996, the Merger and Acquisition Committee met again.
The Committee was informed that the bidder whose preliminary proposal was
determined to be inadequate had indicated that it would be unwilling to increase
its preliminary offer, and was dropped from consideration as a potential buyer.
The Merger and Acquisition Committee also discussed concerns among certain
members that the preliminary offers were lower than what the Committee felt was
a fair price for Eldorado. As part of the discussion, the Merger and Acquisition
Committee also discussed alternatives to selling Eldorado, including the
acquisition of another financial institution or a possible stock repurchase
program. It was decided that it would be premature to decide on any alternative
course of action until final bids for Eldorado had been received and evaluated.

         On October 16, 1996, the Board of Directors met, along with Eldorado's
legal counsel and a representative from Sheshunoff, to discuss and review all
options which were available to Eldorado, including each of the three
preliminary proposals to acquire Eldorado. The issue was raised as to what was
the best offer that Eldorado would likely receive in the current market.
Sheshunoff's representative advised the Board that a $24 per share price would
be at the highest end of the range, and that a $24 per share all-cash offer was
extremely optimistic. Subsequent to this meeting, representatives from
Sheshunoff had numerous contacts with each of the three bidders with the
objective of receiving final bids from each. Eldorado subsequently received
final proposals from each of the potential buyers.

         On November 15, 1996, the Executive Committee of the Board of Directors
met, along with Eldorado's legal counsel, in order to discuss the final
proposals from three separate entities which were presented at such meeting by
representatives of Sheshunoff. The final proposals included a bid from CSBI
which provided for either: (i) an all-cash transaction at a price of $22.25 per
share of Eldorado Common Stock (for an approximate aggregate value of $84.2
million); (ii) an all-stock transaction using CSBI's common stock which CSBI
valued at a price of $25.60 per share of Eldorado Common Stock (for an
approximate aggregate value of $97 million) but which value was discounted due
to the illiquid nature of the stock and other factors (as discussed below); or
(iii) a 30% cash, 70% stock transaction which CSBI valued at a price of $22.25
per share of Eldorado Common Stock (for an approximate aggregate value of $84.2
million). The other two proposals included a stock transaction which the bidder
valued at a price of $24 per share of Eldorado Common Stock but which value was
discounted due to the illiquid nature of the stock and other factors (as
discussed below), and a transaction in which the consideration offered by the
bidder was payable in cash or the bidder's stock, in each case at a price lower
than that of the other two offers.

         The Executive Committee then discussed the relative merits of each
proposal. The Committee noted that neither CSBI nor another bidder which offered
to pay consideration solely in its own shares of stock had stock which was
actively traded on either a national exchange or the NASDAQ National Market, and
that Eldorado's Common Stock was currently listed and actively traded on the
American Stock Exchange. Sheshunoff advised the Committee that, in its opinion,
the all-stock offers should be valued at a price lower than the value stated by
the bidders due to the absence of a broad market for the bidders' securities,
the limited duration of the bidders' operating histories, uncertainties created
by substantial recent or pending acquisitions made by these bidders, the
difficulty in ascertaining a market value of stock which was closely held and
not actively traded, and the risks inherent in owning stock in which there is
not an active trading market. In its opinion, Sheshunoff indicated that it
valued CSBI's all-stock offer within a range of $19.80 per share and $22.00 per
share (or an estimated nominal value of $75 million to $83 million), CSBI's 30%
cash, 70% stock offer within a range of $19.30 per share and $20.30 per share
(or an estimated nominal value of $73 million to $77 million) and the offer of
the second highest bidder within a range of $18.50 per share and $22.20 per
share (or an estimated nominal value of $70 million to $84 million).

                                       10
<PAGE>   17
         The Executive Committee further noted that listing upon an exchange or
the NASDAQ National Market typically requires the fulfillment of certain
financial and non-financial conditions and the presence of market makers who are
willing and able to make a continuous and orderly market in a company's
securities, as well as requirements with respect to the nature of a listed
company's public "float" (i.e. the number of shares held by persons not
affiliated with the company). In Sheshunoff's opinion, the timing and nature of
the development of any public market for the bidders' stocks was speculative and
should not be considered in determining the relative values of such offers. For
these reasons, the Executive Committee concluded that it would not be prepared
to accept proposals from these institutions in this price range unless their
proposals were changed to provide for an all-cash transaction. Upon the advice
of Sheshunoff's representative, the Executive Committee decided that: (i)
Sheshunoff would contact the bidder which offered only its stock and inform it
that Eldorado would only consider its offer if the consideration was paid
entirely in cash; (ii) Sheshunoff would contact the institution whose offer was
the lowest of the three offers and indicate that it would need to increase the
price range in order to remain in the bidding process, and (iii) Sheshunoff
would contact CSBI and indicate that CSBI would need to present a higher
all-cash offer in order to remain in the bidding process.

         On November 19, 1996, the Executive Committee of the Board of Directors
met with Eldorado's legal counsel and a representative from Sheshunoff to
discuss the responses from each of the bidders. Sheshunoff indicated that, in
response to the communication from the Committee: (i) the institution which had
offered a nominal value of $24.00 for each share of Eldorado Common Stock, which
Sheshunoff discounted to a relative market value of $70 million to $84 million
or $18.50 per share to $22.20 per share based on the considerations discussed
above, revised its offer to an all-cash offer of $81.4 million or $21.50 per
share, or in the alternative a 50% cash, 50% stock offer with a nominal value of
$84.7 million or $22.38 per share (which was discounted to a relative market
value of $79 million to $83 million or $20.90 per share to $22.00 per share),
(ii) the institution which had the lowest offer slightly increased its offer to
$75.7 million or $20 per share in cash or stock, with the ability to convert the
all-stock offer into cash at their discretion in the future in the event that
the market value of such institution's stock were to rise prior to the closing
of any transaction with Eldorado (which would prevent Eldorado's shareholders
from the realizing the benefit of a rise in the stock price of that institution)
and (iii) CSBI increased its cash offer to $87.1 million or $23.00 for each
share of Common Stock, with Eldorado's payment of regular dividends to be
continued through the completion of any transaction. After discussion, the
Executive Committee recommended to the Board of Directors that the Board
undertake negotiations with CSBI. This recommendation was based upon the fact
that CSBI presented the highest cash offer per share, and that the only
nominally higher offers received were contingent upon the consideration being
paid in stock for which there existed no active trading market, and in one
instance by an institution which was not, in the view of the Executive
Committee, an established, well-seasoned financial institution with an adequate
and realistic business plan for its future operations. In addition, none of the
other entities which had offered stock for Eldorado Common Stock had a history
of paying regular dividends, and in fact one of the bidders explicitly rejected
a proposal which would have provided for continued dividends for Eldorado
shareholders after any merger.

         On November 20, 1996, the Board of Directors met to discuss Eldorado's
options. Present at that meeting was Eldorado's legal counsel as well as
representatives of Sheshunoff. At this meeting, Sheshunoff presented an overview
of the banking market. Sheshunoff indicated that the banking industry was
undergoing a period of consolidation. As a result of these changes, the industry
was becoming intensely competitive, with major institutions competing strictly
through pricing. In order to compete successfully in this type of environment,
it would be likely that Eldorado would have to greatly increase its size, most
likely through a series of acquisitions. Sheshunoff indicated that increased
rate competition in the banking industry would put increasing pressures on
Eldorado's profit margins and would adversely affect its results of operations.
With respect to making one or more acquisitions, Sheshunoff advised the Board
that prices for financial institutions are currently quite high, which would
likely make any acquisition by Eldorado somewhat expensive. With respect to a
stock repurchase program, Sheshunoff indicated that this was normally a
long-term process, and that such a program could interfere with any potential
acquisition by Eldorado of another financial institution. Sheshunoff further
advised the Board that the offer from CSBI was at a high price level as compared
to other bank transactions which had recently occurred in California and that,
in this context, the CSBI transaction was a very attractive transaction for
Eldorado.

         After a discussion of all of the alternatives available to Eldorado,
including a discussion of the relative merits of the competing proposals in
which the recommendations of the Executive Committee were reviewed and ratified,
the Board voted to commence negotiations with CSBI in order to enter into a
definitive agreement based on the offer presented to Eldorado by CSBI. The
Board's decision was based upon a number of factors. In considering whether
Eldorado should

                                       11
<PAGE>   18
remain independent, the Board considered, based in part on Sheshunoff's
analysis, a range of possible values to Eldorado's shareholders that could
possibly be achieved by Eldorado remaining independent. In this regard, the
Board considered the considerable risks inherent in remaining independent that
could affect Eldorado's ability to realize strong earnings in the future,
including, among other reasons, the impact of the volatility of general interest
rates, volatility in the capital markets which could affect Eldorado's stock
price, problems in the California economy, increased competition for deposits
and loans in the Southern California marketplace, and the high price to be paid
for potential acquisitions. The Board also noted the difficulties encountered in
attempting to pursue an acquisition strategy during the previous two years. The
Board decided that the risks of remaining independent were substantial enough so
that the offer from CSBI presented the best opportunity for Eldorado's
shareholders to realize the maximum return on their investment in Eldorado.

         Negotiations with respect to a proposed acquisition of Eldorado were
commenced with CSBI in November 1996. Because CSBI would be raising money from
outside investors to finance the proposed acquisition, CSBI's ability to finance
the transaction was of concern to the Board of Directors. Based on information
provided by CSBI to Sheshunoff, and because of CSBI's financial history and
resources, in Sheshunoff's judgment CSBI would be able to fund the proposed
transaction. The Board of Directors further concluded that one of Eldorado's
goals during negotiations with CSBI would be to ensure that, because CSBI would
be raising funds from outside investors to fund the Merger Consideration,
Eldorado would be compensated in case CSBI was unable to raise such funds. As a
result of these negotiations, a definitive merger agreement was prepared in
which CSBI would deposit the sum of $4.5 million in escrow (the "Deposit"),
which would thereafter be distributed to Eldorado in the event, among other
things, CSBI was unable to raise sufficient funds to pay the entire Merger
Consideration. On February 13, 1997, CSBI notified Eldorado that CSBI had
entered into a funding agreement that, in combination with prior funding
commitments, provided for the funding of the entire amount of the Merger
Consideration.

         The Board of Directors approved the terms and conditions of the Merger
Agreement at a special meeting held on December 21, 1996. In evaluating the
terms of the Merger Agreement, the Board of Directors also considered the
proposed restrictions on solicitation by Eldorado of competing acquisition or
merger proposals and the effect that the Termination Fee (as defined below; see
" Termination of the Merger Agreement" and " The Stock Option Agreement.") might
have on potential unsolicited acquisition or merger proposals from third parties
that might be interested in acquiring Eldorado. In agreeing to the restrictions
on solicitation of competing merger proposals, the Board of Directors was
advised by CSBI that it would not proceed with the Merger if Eldorado insisted
on a provision which would allow Eldorado to solicit other offers. The Board of
Directors was not prepared to jeopardize the proposed Merger in order to
preserve an opportunity to seek other offers that might never materialize. In
agreeing to the Termination Fee, the Board of Directors concluded that it was
unlikely that Eldorado would receive a competing merger proposal that, from a
financial standpoint, would be superior to CSBI's merger proposal, based on the
fact that Sheshunoff had solicited interest from a large number of institutions,
with only four presenting proposals, and the per share cash merger compensation
offered by CSBI was higher than all of the other bids and was in the high end of
the range anticipated by Sheshunoff. Other factors considered by the Board of
Directors in considering whether to enter into the Merger Agreement included the
opinion of Sheshunoff that the Merger Consideration was fair to Eldorado's
shareholders from a financial point of view, the financial and managerial
strength of CSBI, CSBI's ability to finance the Merger and the fact that the
transaction would be taxable to the Company's shareholders as offset by the
opportunity afforded to Eldorado's shareholders to receive consideration
consisting entirely of cash in exchange for their shares of Common Stock. The
Board did not assign any specific or relative weight to the foregoing factors in
its considerations.

         THE BOARD OF DIRECTORS OF ELDORADO HAS CAREFULLY CONSIDERED AND
UNANIMOUSLY APPROVED THE TERMS OF THE MERGER AGREEMENT AND THE MERGER. THE BOARD

OPINION OF FINANCIAL ADVISOR

         Sheshunoff is an investment banking and consulting firm specializing in
the banking industry. Eldorado retained Sheshunoff based upon its
qualifications, expertise and reputation to provide its opinion of fairness of
the Merger Consideration to be received by Eldorado's shareholders in connection
with the Merger. At the December 21, 1996 meeting of the Eldorado Board of
Directors, Sheshunoff rendered its written opinion to the Board of Directors
that, as of such date, the consideration to be received in the Merger Agreement
was fair from a financial point of view to the holders of the Common Stock.

         The full text of Sheshunoff's opinion, which sets forth, among other
things, assumptions made, procedures followed, matters considered, and
limitations on the review undertaken, is attached as Appendix C to this Proxy
Statement. Eldorado's shareholders are urged to read the Sheshunoff opinion
carefully and in its entirety. Sheshunoff's opinion is addressed to Eldorado's
Board of Directors and does not constitute a recommendation to any shareholder
of Eldorado as to how such shareholder should vote at the Special Meeting.

         In connection with rendering its written opinion, Sheshunoff, among
other things: (i) analyzed certain internal financial statements and other
financial and operating data concerning Eldorado prepared by the management of
Eldorado; (ii) analyzed certain publicly available financial statements, both
audited and unaudited, of Eldorado, including those included in Eldorado's
annual reports for each of the years ended December 31, 1993, 1994 and 1995, and
Eldorado's quarterly report for the period ended September 30, 1996; (iii)
analyzed certain internal financial statements and other financial and operating
data concerning Eldorado prepared by the management of Eldorado; (iv) analyzed
certain financial projections of Eldorado prepared by Sheshunoff in coordination
with the management of Eldorado; (v) discussed certain aspects of the past and
current business operations, financial condition and future prospects of
Eldorado with certain members of its management; (vi) reviewed reported market
prices and historical trading activity of Eldorado Common Stock; (vii) reviewed
the financial terms, to the extent publicly available, of certain comparable
precedent transactions; (viii) reviewed the Merger Agreement; (ix) considered
the sufficiency of certain preliminary written commitments received by CSBI with
respect to raising the funds which are necessary to complete the funding of the
Merger (the "Funding Documents"); however, Sheshunoff did not consider
Eldorado's and CSBI's ability to legally enforce such Funding Documents; and (x)
performed such other analyses as Sheshunoff has deemed appropriate.

         In connection with its review, Sheshunoff relied upon and assumed the
accuracy and completeness of all of the foregoing information provided to it or
made publicly available, and Sheshunoff has not assumed any responsibility for
independent verification of such information. With respect to the financial
projections, Sheshunoff assumed that they have been reasonably prepared on the
basis reflecting the best currently available estimates and judgments of the
future financial performance of Eldorado. However, the assumptions used to make
projections of future performance are not certain to become reality. If the
projections do not become reality, actual performance may vary substantially
from the projected results. Sheshunoff has not made any independent evaluation
or appraisal of the assets or liabilities of Eldorado, nor has Sheshunoff been
furnished with any such appraisals, and Sheshunoff has not examined any
individual loan files of Eldorado. Sheshunoff is not an expert in the evaluation
of loan portfolios for the purposes of assessing the adequacy of the allowance
for losses with respect thereto and has assumed that such allowance for Eldorado
is adequate to cover such losses. Sheshunoff's opinion is necessarily based on
economic, market and other conditions as in effect on, and the information made
available to Sheshunoff as of, the date of the opinion.

         In connection with rendering its opinion, Sheshunoff performed a
variety of financial analyses. The preparation of a fairness opinion involves
various determinations as to the most appropriate and relevant methods of
financial analysis and the application of those methods to the particular
circumstances and, therefore, such an opinion is not readily susceptible to
partial analysis or summary description. Moreover, the evaluation of the
fairness, from a financial point of view, of the consideration to be received by
the holders of the Common Stock is to some extent a subjective one based on the
experience and judgment of Sheshunoff and not merely the result of mathematical
analysis of financial data. Accordingly, notwithstanding the separate factors
summarized below, Sheshunoff believes that its analyses must be considered as a
whole and that selecting portions of its analyses and of the factors considered
by it, without considering all analyses and factors, could create an incomplete
view of the evaluation process underlying its opinion. The ranges of valuations
resulting from any particular analysis described below should not be taken to be
Sheshunoff's view of the actual value of Eldorado.

                                       13
<PAGE>   20
         In performing its analyses, Sheshunoff made numerous assumptions with
respect to industry performance, business and economic conditions and other
matters, many of which are beyond the control of Eldorado. The analyses
performed by Sheshunoff are not necessarily indicative of actual values or
future results, which may be significantly more or less favorable than suggested
by such analyses. The analyses do not purport to be appraisals or to reflect the
prices at which a company might actually be sold. In addition, Sheshunoff's
analyses should not be viewed as determinative of the opinion of either the
Board of Directors or the management of Eldorado with respect to the value of
Eldorado.

         The following is a summary of the analyses performed by Sheshunoff in
connection with its opinion delivered to the Board of Directors on December 21,
1996: 
         Analysis of Selected Transactions. Sheshunoff performed an analysis of
premiums paid in selected pending or recently completed acquisitions of banking
organizations in California which sold for cash or a combination of cash and
stock, with comparable characteristics to the proposed Merger. Two sets of
comparable transactions were analyzed to ensure a thorough comparison.

         The first set of guideline transactions specifically consisted of 13
mergers and acquisitions of banking organizations in California for cash from
December 18, 1995 to December 18, 1996 with seller's total assets less than $1
billion and with positive net income for the last twelve months (the "cash
transactions"). The analysis yielded multiples of the cash transactions'
purchase price relative to: (i) book value, ranging from 1.03 times to 1.96
times with an average of 1.58 times and a median of 1.57 times (compared with a
value for the Merger of 1.91 times September 30, 1996 book value); (ii) tangible
book value, ranging from 1.03 times to 1.95 times with an average of 1.56 times
and a median of 1.60 times (compared with a value for the Merger of 2.21 times
September 30, 1996 tangible book value); (iii) last 12 months earnings, ranging
from 10.0 times to 56.2 times with an average of 22.9 times and a median of 17.1
times (compared with a value for the Merger of 16.2 times last 12 months
earnings as of September 30, 1996); (iv) deposits, ranging from 11.6% to 23.6%
with an average of 17.6% and a median of 18.0% (compared to a value for the
Merger of 27.3% of September 30, 1996 deposits); and (v) total assets, ranging
between 10.5% and 20.2% with an average of 15.6% and a median of 15.8% (compared
with a value for the Merger of 23.6% of September 30, 1996 total assets).

         The second set of guideline transactions specifically consisted of 22
mergers and acquisitions of banking organizations in California for a
combination of cash and/or stock (or a combination of cash and stock) from
December 18, 1995 to December 18, 1996 with seller's total assets less than $1
billion and positive net income for the last twelve months (the "mixed
transactions"). The analysis yielded multiples of the mixed transactions'
purchase price relative to: (i) book value, ranging from 1.03 times to 1.96
times with an average of 1.60 times and a median of 1.60 times (compared with a
value for the Merger of 1.91 times September 30, 1996 book value); (ii) tangible
book value, ranging from 1.03 times to 1.99 times with an average of 1.60 times
and a median of 1.63 times (compared to a value for the Merger of 2.21 times
September 30, 1996 tangible book value); (iii) last 12 months earnings, ranging
from 10.0 times to 56.2 times with an average of 23.2 times and a median of 16.8
times (compared with a value for the Merger of 16.2 times last 12 months
earnings as of September 30, 1996); (iv) deposits, ranging from 11.6% to 23.6%
with an average of 17.4% and a median of 18.0% (compared to a value for the
Merger of 27.3% of September 30, 1996 deposits); and (v) total assets, ranging
between 10.5% and 20.2% with an average of 15.4% and a median of 15.5% (compared
with a value for the Merger of 23.6% of September 30, 1996 total assets).

         In addition to the above analysis, Sheshunoff compared Eldorado's
premium to market value as of 3 months, 1 month and 6 days prior to the date of
announcement as compared to the premiums received by the comparable companies.
Eldorado's deal value per share was 125.2%, 108.9% and 110.8% higher than its
market trading price 3 months, 1 month and 6 days before the date of
announcement, respectively. The cash transactions' median premiums were 152.6%,
126.6% and 120.2% above their 3 month, 1 month and 6 day trading prices prior to
the date of announcement, respectively. The mixed transaction's median premiums
were 142.5%, 126.6%, and 118.2% greater than their 3 month, 1 month and 6 day
trading prices prior to the date of announcement, respectively.

         Discounted Cash Flow Analysis. Using a discounted cash flow analysis,
Sheshunoff estimated the present value of the future stream of after-tax cash
flow that Eldorado could produce through the year 2001, under various
circumstances, assuming that Eldorado performed in accordance with the
earnings/return projections of management. Sheshunoff

                                       14
<PAGE>   21
estimated the terminal value for Eldorado at the end of the period by applying
multiples of earnings ranging from 10 times to 16 times and then discounting the
cash flow streams, including dividends paid to the shareholders (assuming all
earnings in excess of that required to maintain a tangible equity to tangible
asset ratio of 7.5% are paid out in dividends) and the receipt of a terminal
value for Eldorado, in each case using discount rates ranging from 14.0% to
18.0% chosen to reflect different assumptions regarding the required rates of
return of Eldorado and the inherent risk surrounding the underlying projections.
This discounted cash flow analysis indicated a range of $17.65 per share to
$26.98 per share. The Merger value of $23.00 per share compares favorably to
this estimate. 

         Sheshunoff also performed a cash flow analysis using an estimated
terminal value for Eldorado at the end of the period by applying multiples of
book value ranging from 1.5 times to 2.5 times and then discounting the cash
flow streams, dividends paid to the shareholders (assuming all earnings in
excess of that required to maintain a tangible equity to tangible asset ratio of
7.5% are paid out in dividends) and terminal value using discount rates ranging
from 14.0% to 18.0% chosen to reflect different assumptions regarding the
required rates of return of Eldorado and the inherent risk surrounding the
underlying projections. This discounted cash flow analysis indicated a range of
$14.29 per share to $21.10 per share. The Merger value of $23.00 per share
compares favorably to this estimate.

         No company or transaction used in the comparable transaction analyses
is identical to Eldorado or the Merger. Accordingly, an analysis of the results
of the foregoing necessarily involves complex considerations and judgments
concerning differences in financial and operating characteristics of Eldorado
and other factors that could affect the public trading value of the companies to
which they are being compared. Mathematical analysis (such as determining the
average or median) is not in itself a meaningful method of using comparable
transaction data or comparable company data.

         As part of its investment banking business, Sheshunoff is regularly
engaged in the valuation of securities in connection with mergers and
acquisitions, private placements, and valuations for estate, corporate and other
purposes. The Board of Directors decided to retain Sheshunoff based on its
experience as a financial advisor in mergers and acquisitions of financial
institutions, and its knowledge of financial institutions.

         In addition, Sheshunoff was engaged by Eldorado on August 1, 1996 to
serve as Eldorado's exclusive financial advisor to undertake the following: (a)
develop, update and review with Eldorado on an on-going basis a list of parties
which might be interested in acquiring Eldorado and contact parties on that list
as approved by Eldorado in its sole discretion; (b) assist in the preparation of
a descriptive memorandum of Eldorado; (c) consult with and advise Eldorado
concerning opportunities for the sale of Eldorado, participate on Eldorado's
behalf in negotiations for such sale and assist and advise Eldorado concerning
the value of any non-monetary considerations relating to a transaction; and (d)
if requested by Eldorado, render an opinion with respect to the fairness, from a
financial point of view, to Eldorado's shareholders of the consideration
received. For these services, Sheshunoff will be paid a professional fee of
$592,261 upon closing of the Merger.

         In addition, Alex Sheshunoff Management Services, which together with
Sheshunoff is owned by Alex Sheshunoff & Co., has provided professional services
to Eldorado and Eldorado Bank in the past, including earnings assessments,
product profitability analysis, management change analysis, profit improvement
analysis, trust analysis and educational programs. For these services, Alex
Sheshunoff Management Services was paid total professional fees of $487,015.

DISSENTERS' RIGHTS

         General. If the Merger is approved and consummated, dissenters' rights
will be available to holders of Eldorado Common Stock who exercise such rights
in accordance with Chapter 13 of the California General Corporation Law
("Chapter 13"). THE REQUIRED PROCEDURE SET FORTH IN CHAPTER 13 MUST BE FOLLOWED
EXACTLY OR ANY DISSENTERS' RIGHTS MAY BE LOST. The information set forth below
is a general summary of dissenters' rights and is qualified in its entirety by
reference to Chapter 13, a copy of which is attached hereto as Appendix D.
Shareholders should read Appendix D in its entirety for more complete
information concerning dissenters' rights.

         Each holder of shares of Eldorado Common Stock which were outstanding
as of the Record Date who follows the procedures set forth in Chapter 13 and who
votes against the proposal to approve the Merger Agreement will be entitled to

                                       15
<PAGE>   22
demand the purchase of such holder's shares of Common Stock for a cash purchase
price equal to the fair market value of such holder's shares, so long as demands
for such payment are properly and timely filed by Eldorado shareholders who own
five percent or more of the outstanding shares of Eldorado Common Stock. The
fair market value of shares of Eldorado Common Stock will be determined as of
December 23, 1996, the day before the public announcement of the Merger
Agreement, excluding any appreciation or depreciation as a consequence of the
proposed Merger, but adjusted for any stock split, reverse stock split or share
dividend which becomes effective thereafter.

         In order to be entitled to exercise dissenters' rights, a shareholder
of Eldorado must vote "AGAINST" the Merger Agreement and the Merger. Thus, any
shareholder who wishes to dissent and executes and returns a proxy in the
accompanying form must specify that such holder's shares are to be voted
"AGAINST" the proposal to approve the Merger Agreement and the Merger. If the
shareholder returns a proxy without voting instructions or with instructions to
vote "FOR" or to "ABSTAIN" on the proposal to approve the Merger Agreement and
the Merger, such holder's shares will not be voted against the Merger Agreement
and the Merger and the shareholder will lose its dissenters' rights.

         A shareholder of Eldorado electing to exercise dissenters' rights must
also make written demand upon Eldorado for the purchase of dissenting shares and
payment to such shareholder in cash of their fair market value. However, no such
demand by a shareholder of Eldorado will be effective for any purpose unless it
is received by Eldorado or Eldorado's transfer agent on or prior to the date of
the Special Meeting. The demand should specify the number of shares held of
record by such shareholder which the shareholder demands to be purchased and a
statement of what the shareholder claims to be the fair market value of those
shares as of December 23, 1996. Such statement of the fair market value of the
shares of Eldorado Common Stock constitutes an offer by the shareholder to sell
the shares at that price. Eldorado's transfer agent is ChaseMellon Shareholder
Services LLC, and its address is 85 Challenger Road, Ridgefield Park, New Jersey
97660.

         If the Merger Agreement is approved by Eldorado's shareholders and
demands for payment have been properly and timely filed by holders of five
percent or more of the outstanding shares of Eldorado Common Stock, Eldorado
will have ten days after such approval to mail a notice of such approval to each
shareholder of Eldorado who voted against the Merger Agreement, together with a
copy of Sections 1300 to 1304 of Chapter 13, a statement of the price determined
by Eldorado to represent the fair market value of the dissenting shares as of
December 23, 1996 and a brief description of the procedure to be followed if the
shareholder desires to exercise dissenters' rights.

         Within 30 days after the date on which notice of the approval of the
Merger Agreement is mailed, the dissenting shareholder must surrender to
Eldorado, at its principal office or at the office of Eldorado's transfer agent,
the certificates representing the dissenting shares to be stamped or endorsed
with a statement that they are dissenting shares or to be exchanged for
certificates of appropriate denomination so stamped or endorsed. Any shares of
Eldorado Common Stock that are transferred prior to their submission for
endorsement lose their status as dissenting shares.

         If Eldorado and the dissenting shareholder agree that the surrendered
shares are dissenting shares and agree upon the price of the shares, the
dissenting shareholder will be entitled to the agreed price with interest
thereon at the legal rate on judgments from the date of such agreement (set by
law in California at 10% per annum), so long as demands for such consideration
are properly filed with respect to five percent or more of the outstanding
shares of Eldorado Common Stock. Subject to the restrictions imposed under the
California General Corporation Law on the ability of Eldorado to purchase its
outstanding shares, payment of the fair market value of the dissenting shares
shall be made within 30 days after the amount thereof has been agreed upon or 30
days after any statutory or contractual conditions to the Merger have been
satisfied, whichever is later, subject to the surrender of the certificates
therefor, unless provided otherwise by agreement.

         If Eldorado denies that the shares surrendered are dissenting shares,
or if Eldorado and the dissenting shareholder fail to agree upon a fair market
value of such shares of Eldorado Common Stock, then the dissenting shareholder
must, within six months after the notice of approval of the Merger Agreement and
the Merger is mailed, file a complaint in the Superior Court of Orange County,
California requesting the court to make such determinations or intervene in any
pending action brought by any other dissenting shareholder. If the complaint is
not filed or intervention in a pending action is not made within the specified
six-month period, the dissenter's rights will be lost. If the fair market value
of the dissenting shares is at issue, the court will determine, or will appoint
one or more impartial appraisers to determine, such fair market value. Any such
determination of the fair market value of any dissenting shares of Eldorado may
be more than, less than or

                                       16
<PAGE>   23
equal to the fair market value of the shares of Eldorado Common Stock as of the
date of the Special Meeting or as of the Effective Time of the Merger.

         No dissenting shareholder who has elected to proceed under Chapter 13
may withdraw his or her dissent or demand for payment unless Eldorado consents
to such withdrawal.

         It is a condition to the obligations of CSBI to consummate the Merger
that holders of no more than 15% of the outstanding shares of Common Stock make
a demand for purchase under Chapter 13.

         ELDORADO SHAREHOLDERS WILL NOT HAVE DISSENTERS' RIGHTS UNLESS DEMANDS
FOR PURCHASE AND PAYMENT ARE RECEIVED BY ELDORADO OR ELDORADO'S TRANSFER AGENT
ON OR PRIOR TO THE DATE OF THE SPECIAL MEETING FROM HOLDERS OF RECORD OF COMMON
STOCK OF FIVE PERCENT OR MORE OF THE OUTSTANDING SHARES OF ELDORADO COMMON STOCK
WHO HAVE VOTED AGAINST THE MERGER.

HOW TO SURRENDER AND RECEIVE PAYMENT FOR SHARES

         Within two days after the Effective Time of the Merger, Eldorado will
provide for the mailing to each holder of record of shares of Eldorado Common
Stock a letter of transmittal and instructions for use in effecting the
surrender of stock certificates which, immediately prior to the Effective Time
represented shares of Common Stock, in exchange for the Merger Consideration.
Upon the proper surrender of such stock certificate(s), together with a properly
completed and duly executed letter of transmittal, the holder of such stock
certificate(s) shall be entitled to receive, in exchange therefor, a check in
the amount equal to the product of $23.00 and the number of shares of Common
Stock represented by such stock certificate(s), and any such stock
certificate(s) so surrendered shall forthwith be canceled. No interest will be
paid or accrued on the Merger Consideration. Those shareholders which will
receive in excess of $1,000,000 of Merger Consideration may, if so desired, make
arrangements in order to obtain payment in same-day funds immediately following
the Effective Time.

         ELDORADO SHAREHOLDERS ARE REQUESTED NOT TO SURRENDER THEIR STOCK
CERTIFICATE(S) FOR EXCHANGE UNTIL THEY HAVE RECEIVED SUCH INSTRUCTIONS AND
LETTER OF TRANSMITTAL AND HAVE COMPLETED THE LETTER OF TRANSMITTAL.

         In the event of a transfer of ownership of any shares of Common Stock
that has not been registered in the transfer records of Eldorado, a check for
the Merger Consideration may be issued to the transferee if the stock
certificate(s) representing such shares of Common Stock is presented accompanied
by documents sufficient, in the reasonable discretion of Eldorado and its
transfer agent, to evidence and effect such transfer and to evidence that all
applicable stock transfer taxes have been paid.

         From and after the Effective Time, there shall be no transfers on the
stock transfer records of Eldorado of any shares of Common Stock that were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, any stock certificate(s) representing such shares is presented, the stock
certificate(s) shall be canceled and exchanged for the Merger Consideration
deliverable in respect thereof in accordance with the procedures set forth in
the Merger Agreement.

         Any portion of the aggregate Merger Consideration that remains
unclaimed by Eldorado shareholders for six months after the Effective Time shall
be repaid to CSBI, upon demand. Any Eldorado shareholders who have not
theretofore complied with the procedures regarding payment for shares in
accordance with the Merger Agreement shall thereafter look only to CSBI for
payment of the Merger Consideration deliverable in respect of each share of
Common Stock such shareholder holds as determined pursuant to the Merger
Agreement, without any interest thereon. Notwithstanding the foregoing, none of
CSBI, Eldorado nor any other person shall be liable to any former holder of
Common Stock for any amount delivered to a public official pursuant to
applicable abandoned property laws.

         In the event any stock certificate(s) shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such stock certificate(s) to be lost, stolen or destroyed and, if required by
Eldorado, the posting

                                       17
<PAGE>   24
by such person of a bond in such amount as Eldorado may direct as indemnity
against any claim that may be made against it with respect to such stock
certificate(s), such person will be issued in exchange for such lost, stolen or
destroyed stock certificate(s), the Merger Consideration deliverable in respect
thereof pursuant to the Merger Agreement.

CANCELLATION OF STOCK OPTIONS

         As of March 14, 1997, Eldorado had outstanding options to purchase
290,193 shares of Common Stock pursuant to Eldorado's stock option plans.
Eldorado has agreed that, prior to the Effective Time, it will make arrangements
for the cancellation of all options then outstanding, whether or not currently
vested, so that as of the Effective Time of the Merger there will be no options
outstanding.

         In consideration for the cancellation of their stock options,
optionholders will be entitled to receive a cash payment in an amount equal to
the difference between $23.00 and the option exercise price per share for each
option outstanding (an "Option Cancellation Payment"). Shares of Common Stock
issued upon the exercise of stock options prior to the Effective Time of the
Merger will be converted into the right to receive cash in accordance with the
terms of the Merger Agreement.

         Under the terms of the Merger Agreement, CSBI may enter into agreements
with Eldorado optionholders on an individual basis under which such
optionholders may forego the Option Cancellation Payment due them in exchange
for an option to purchase CSBI common stock or other consideration. However, no
such agreement may provide that the optionholder would receive a cash payment in
excess of the Option Cancellation Payment otherwise due to the optionholder.

CLOSING DATE

         Unless Eldorado and CSBI shall mutually select another date, the
closing of the transactions contemplated by the Merger Agreement (the "Closing")
shall take place on such date (the "Closing Date") that is five business days
following the expiration of all applicable waiting periods in connection with
approvals of governmental authorities and the receipt of all approvals of all
governmental authorities and after all other conditions to the consummation of
the Merger are satisfied or waived. If the Closing does not occur by August 1,
1997, then either Eldorado or CSBI may terminate the Merger Agreement, unless
the terminating party has caused a delay in the Closing as a result of the
terminating party's breach of any of its representations, warranties, covenants
or agreements contained in the Merger Agreement, or all approvals of
governmental authorities have been received and Eldorado and CSBI are in the
"waiting period" (normally of 15 days) relating to the U.S. Department of
Justice review.

CONDITIONS TO THE MERGER

         The obligations of each party to consummate the Merger are subject to
the conditions that the Merger shall have been approved by the holders of a
majority of Eldorado Common Stock, that no legal or administrative proceedings
shall be pending to restrain or prohibit the Merger and that all required
regulatory approvals shall have been obtained. See " Regulatory Approvals
Required."

         The obligations of CSBI to consummate the Merger are subject to certain
additional conditions, including the accuracy of the representations and
warranties made by Eldorado in the Merger Agreement, the performance by Eldorado
of the agreements and covenants to be performed by it on or prior to the Closing
Date, the receipt of legal opinions and auditors' letters, the receipt of all
third party consents which are necessary to permit the Merger, the absence of
any material adverse change in the financial condition or results of operations
of Eldorado, the absence of any change in the number of outstanding shares of
Common Stock (other than shares issued upon the exercise of stock options
outstanding as of the date of the Merger Agreement), the cancellation of all
stock options, and the requirement that the aggregate number of shares of the
Common Stock affirmatively voting against the Merger or owned by persons who
have given notice that they intend to demand that Eldorado purchase their shares
under Chapter 13 shall not constitute more than 15.0% of all shares of Eldorado
Common Stock outstanding immediately prior to the Closing Date.

         The obligations of Eldorado to consummate the Merger are subject to
certain additional conditions, including the performance by CSBI of the
agreements and covenants to be performed by it on or prior to the Closing Date,
the receipt of

                                       18
<PAGE>   25
legal opinions, the cancellation of all stock options and the receipt by the
Exchange Agent of the aggregate Merger Consideration from CSBI.

CONDUCT PENDING THE MERGER

         Between the date of the Merger Agreement and the Closing Date, Eldorado
has, among other things, agreed to: (i) refrain from negotiations with any other
entity concerning an acquisition proposal; (ii) make available to CSBI all
information regarding Eldorado that CSBI may reasonably request; (iii) use its
best efforts to bring about the specific conditions of the Merger Agreement;
(iv) advise CSBI of any material change in Eldorado's capital structure,
financial condition or business prospects; (v) promptly provide CSBI with
current information about Eldorado; (vi) conduct its business only in the normal
course with certain events or contemplated actions requiring the prior written
consent of CSBI and preserve its present business organization, business
relationships, and retain the services of its officers and key employees; (vii)
refrain from paying any dividend, other than normal scheduled quarterly cash
dividends; (viii) refrain from issuing any additional securities; (ix) refrain
from selling, leasing, assigning or otherwise disposing of any property or
asset, with certain exceptions; (ix) refrain from increasing the compensation or
fringe benefits payable to any officer or employee, subject to certain
exceptions in the usual and ordinary course of business and (x) refrain from
making, amending or renewing, or entering into any commitment to make, amend or
renew, any loan exceeding certain dollar thresholds without the prior consent of
CSBI, subject to certain exceptions.

         Between the date of the Merger Agreement and the Closing Date, CSBI has
agreed, among other things, to: (i) use its best efforts to bring about specific
conditions of the Merger Agreement; (ii) advise Eldorado promptly of any
material adverse change to the capital, financial condition or business
prospects of CSBI; and (iii) provide Eldorado with monthly updates regarding the
status of CSBI's financing of the Merger Consideration.

         Each party has agreed to take all corporate actions required of it and
to prepare and file all applications for regulatory approvals with respect to
the Merger, to cooperate fully with the other party in the preparation of the
other party's applications and to seek all necessary consents from third
parties.

EXPENSES

         Except as provided with respect to termination, each of Eldorado and
CSBI is responsible for its own costs and expenses incurred in connection with
the Merger.

TERMINATION OF THE MERGER AGREEMENT

         The Merger Agreement may be terminated by CSBI under the following
circumstances:

         (a) Eldorado has materially breached any representation or warranty
contained in the Merger Agreement or materially failed to satisfy or comply with
any of its agreements and covenants in the Merger Agreement, and Eldorado has
not successfully corrected the grounds for termination within 10 business days
of the notice of breach or default;

         (b) Eldorado has not reaffirmed its intent to proceed with the Merger
following Eldorado's receipt of a Qualifying Strategic Transaction Proposal, as
defined below, or the Board of Directors fails to recommend approval of the
Merger Agreement and the Merger to Eldorado's shareholders or withdraws its
recommendation of approval prior to the Special Meeting; or

         (c) Eldorado fails to meet all the conditions to CSBI's performance as
specified in the Merger Agreement or, if in the reasonable judgment of CSBI, a
matter occurring after the date of the Merger Agreement but prior to the Closing
Date has had, or could reasonably expected to have, a material adverse effect on
Eldorado or Eldorado's ability to consummate the Merger.

                                       19
<PAGE>   26
         The Merger Agreement may be terminated by Eldorado under the following
circumstances:

         (a) CSBI has failed to satisfy or comply with, in any material respect,
any of its agreements and covenants in the Merger Agreement and has not
successfully corrected the grounds for termination within the period set forth
in the Merger Agreement for curing such breach or failure;

         (b) Eldorado receives a "Qualifying Strategic Transaction Proposal," as
defined below;

         (c) Eldorado's shareholders fail to approve the Merger Agreement and
the Merger, provided that the Board of Directors has given and not withdrawn its
recommendation of approval; or

         (d) CSBI fails to meet all the conditions to Eldorado's performance as
specified in the Merger Agreement.

         The Merger Agreement may be terminated by either party: (a) upon the
denial of any required regulatory approval; or (b) if the Closing has not
occurred by August 1, 1997, provided that a party may not terminate the Merger
Agreement if the reason the Closing has not occurred is due to the breach by
such party of any of its representations, warranties, covenants or agreements
contained in the Merger Agreement, or if by August 1, 1997 all regulatory
approvals have been obtained, and the parties are in the 15-day "waiting period"
pertaining to U.S. Department of Justice review.

         The Merger Agreement may be amended or terminated at any time by the
mutual written agreement of the parties.

         Eldorado has agreed to pay CSBI a termination fee if the Merger
Agreement and the Merger are terminated under certain circumstances (the
"Termination Fee"). In the event that a termination occurs because Eldorado has
received a "Qualifying Strategic Transaction Proposal," as defined below, or in
the event the Merger Agreement and the Merger are terminated by CSBI because the
Board of Directors failed to give its recommendation of approval or withdrew its
recommendation of approval to the shareholders, then Eldorado has agreed to
provide to CSBI the Termination Fee, which consists of (i) a cash payment by
Eldorado of $3,500,000, and (ii) the immediate exercisability of an option
previously issued by Eldorado to CSBI to purchase shares of Eldorado Common
Stock. See " The Stock Option Agreement."

         In the event the Merger Agreement and the Merger are terminated by CSBI
if Eldorado's shareholders have not approved the Merger on or before August 1,
1997, or if the Merger Agreement and the Merger are terminated by Eldorado
because Eldorado's shareholders have failed to approve the Merger, then Eldorado
has agreed to reimburse CSBI for all of its reasonable and documented expenses;
provided, however, that Eldorado's liability for such reimbursement shall not
exceed $400,000 if Eldorado reimburses CSBI for such expenses within 10 business
days after its receipt from CSBI of an invoice for such expenses. The timely
payment by Eldorado of CSBI's expenses shall constitute an exclusive remedy for
CSBI for any potential claims against Eldorado under the Merger Agreement so
long as CSBI does not claim that Eldorado has breached the Merger Agreement at
the time CSBI delivers an invoice for reimbursement of its expenses to Eldorado.
Once CSBI receives and accepts Eldorado's payment, CSBI will be barred from
recovering any damages for any breach by Eldorado of any terms of the Merger
Agreement. In addition, once CSBI receives and accepts the timely payment of the
Termination Fee from Eldorado in accordance with the terms of the Merger
Agreement, CSBI will be barred from recovering any damages for any breach of any
terms of the Merger Agreement from Eldorado.

         In the event that the Merger Agreement and the Merger are terminated by
Eldorado because (i) CSBI has materially breached any representation or warranty
contained in the Merger Agreement or has failed to perform in any material
respect any of its agreements and covenants contained in the Merger Agreement,
(ii) CSBI has failed to provide the entire amount of the Merger Consideration to
the Exchange Agent or if CSBI fails to provide Eldorado with reasonably
satisfactory assurances that CSBI will be able to deliver the entire amount of
the Merger Consideration at the Closing, or (iii) if any of the conditions to
the obligation of Eldorado to consummate the Merger have not occurred as of the
Closing Date, then in each case CSBI has agreed that the Deposit, which is
currently held in escrow (the "Deposit Escrow") will be released to Eldorado. If
Eldorado becomes entitled to the Deposit, and CSBI does not make any objection
to the release of the Deposit from the Deposit Escrow to Eldorado within 10
calendar days of a notice to CSBI that Eldorado has made a demand for receipt of
the Deposit, then Eldorado's receipt of such Deposit shall constitute an
exclusive remedy and Eldorado shall be barred from recovering any damages for
any breach by CSBI of any term of the Merger Agreement.

                                       20
<PAGE>   27
         For purposes of the Merger Agreement, a "Strategic Transaction
Proposal" means any proposal regarding any acquisition or purchase of all or a
significant (i.e., more than 20%) portion of the assets of Eldorado or a
significant equity interest in Eldorado, any merger or other business
combination involving Eldorado, any recapitalization involving Eldorado
resulting in an extraordinary dividend or distribution to Eldorado's
shareholders or a self-tender for or redemption of 35% or more of Eldorado
Common Stock. Although Eldorado is generally prohibited from soliciting or
encouraging, directly or indirectly, any Strategic Transaction Proposals, the
Merger Agreement anticipates the possibility that Eldorado may receive a
"Qualifying Strategic Transaction Proposal." A "Qualifying Strategic Transaction
Proposal" is a Strategic Transaction Proposal in which the Board of Directors
has determined that, because of the fiduciary duties owed by the Board of
Directors to Eldorado's shareholders, Eldorado is required to engage in
discussions or negotiations with the third party which has made the proposal and
otherwise pursue the proposal, including possibly withdrawing the Board of
Director's recommendation of approval of the Merger Agreement and the Merger
and/or terminating the Merger Agreement. The determination by the Board of
Directors that a Strategic Transaction Proposal qualifies as a Qualifying
Strategic Transaction Proposal must be made after consultation with Eldorado's
legal counsel and after receipt of a written opinion of Eldorado's investment
bankers that such proposal is financially more favorable to Eldorado's
shareholders than are the terms of the Merger.

THE STOCK OPTION AGREEMENT

         One condition to the Merger Agreement was that Eldorado enter into a
Stock Option Agreement with CSBI, dated December 24, 1996 (the "Stock Option
Agreement"). The following is a summary of the terms and conditions of the Stock
Option Agreement, and is qualified in its entirety by reference to the Stock
Option Agreement, a copy of which is attached to this Proxy Statement as
Appendix B.

         Pursuant to the Stock Option Agreement, Eldorado has granted to CSBI an
option (the "Option") to purchase up to 468,200 shares of Eldorado Common Stock
(representing approximately 11% of the issued and outstanding shares of Eldorado
Common Stock after taking into account the shares of Common Stock issuable upon
exercise of the Option) at an exercise price of $22.00 per share (the "Option
Price"). The Option is exercisable only if CSBI becomes entitled to the
Termination Fee pursuant to the Merger Agreement (see "-- Termination of the
Merger Agreement" above) prior to the date on which the Merger Agreement is
terminated. Once the Option becomes exercisable, it will terminate upon the
earliest to occur of: (i) the exercise of the Option in full or (ii) twelve (12)
months following the termination of the Merger Agreement, or such earlier date
as the holder of the Option realizes net profits from the Option of $1,000,000
(the "Option Termination Date").

         In the event Eldorado, prior to the Option Termination Date, enters
into any agreement (i) to consolidate with or merge into any person other than
CSBI or any of its subsidiaries and is not the surviving corporation, (ii) to
permit any person (other than CSBI or any of its subsidiaries) to merge into
Eldorado or Eldorado Bank and although Eldorado or Eldorado Bank is the
surviving corporation, Eldorado Common Stock is exchanged for stock or other
securities of the other person or for cash or other property, or the shares of
Eldorado Common Stock outstanding right before the merger represent less than
33% of the outstanding shares of Eldorado after the merger, or (iii) to sell or
otherwise transfer all or substantially all of Eldorado's or Eldorado Bank's
assets to any person (other than CSBI or any of its subsidiaries), then such
agreement must provide that the Option will be converted into a substitute
option. The holder of such substitute option has the right, prior to the Option
Termination Date, to require the issuer of the substitute option (whether
Eldorado or a surviving corporation) to repurchase such substitute option or the
securities issuable upon the exercise of such substitute option.

         The Stock Option Agreement also contains provisions which generally
limit the amount of total profit on the sales of Common Stock (or other
securities if a substitute option has been issued) to $1,000,000. In the event
that the holder of the Option realizes total profits greater than $1,000,000,
then any remaining unexercised portion of the Option automatically expires.

         The Stock Option Agreement is intended to increase the likelihood that
the Merger will be consummated in accordance with the terms of the Merger
Agreement. Consequently, certain aspects of the Stock Option Agreement might
have the effect of discouraging persons who might now be, or who might prior to
the Effective Time become interested in acquiring all of, or a significant
interest in, Eldorado, from considering or proposing such an acquisition, even
if such

                                       21
<PAGE>   28
persons were prepared to pay a higher price per share for Eldorado Common Stock
than the then-current market price for such shares. The acquisition of Eldorado,
or an interest in Eldorado, or an agreement to do either, could cause the Option
to become exercisable. The existence of the Stock Option Agreement could
significantly increase the cost to a potential acquiror of acquiring Eldorado.
Such increased cost might discourage a potential acquiror from considering or
proposing an acquisition or might result in a potential acquiror proposing to
pay a lower per share price to acquire Eldorado than it might otherwise have
proposed to pay.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

         Although no written agreements have been executed, CSBI has indicated
that it intends to retain the services of substantially all of Eldorado's
officers and employees after the completion of the Merger. If, however, the
employment of certain officers of Eldorado were to be terminated under specified
circumstances following the Merger, these officers would be entitled to
severance benefits under existing employment agreements.

         The employment agreement of Mr. J.B. Crowell (the "Crowell Agreement"),
the President and Chief Executive Officer of Eldorado and the Chief Executive
Officer of Eldorado Bank, provides that in the event of a merger or
reorganization where Eldorado is not the surviving party or more than fifty
percent of the stock of Eldorado is converted into cash or securities, the
Crowell Agreement will be binding on the surviving entity in such
reorganization; however, all outstanding stock options granted to Mr. Crowell
will vest immediately. If Mr. Crowell's employment is terminated subsequent to a
reorganization but prior to the end of the term of the Crowell Agreement, the
surviving entity in such reorganization must pay Mr. Crowell $200,000 per year
for the lesser of one year or until Mr. Crowell reaches the age of 65, but in
either event not less than the lesser of (i) twelve months' salary or (ii) the
balance of the salary payments that would otherwise have been made during the
remaining term of the Crowell Agreement. A salary continuation program also has
been established for Mr. Crowell under which Mr. Crowell (or, in the event of
his death, his heirs) will receive $94,000 per year from Eldorado for 15 years
following his reaching age 65 or his death or disability, whichever first
occurs.

         Each of the employment agreements for Mr. Raymond E. Dellerba (the
Executive Vice President of Eldorado and the President and Chief Operating
Officer of Eldorado Bank) (the "Dellerba Agreement"), Mr. David R. Brown (the
Executive Vice President and Chief Financial Officer of Eldorado and of Eldorado
Bank) (the "Brown Agreement"), Mr. John J. McCauley (the Executive Vice
President of Eldorado Bank) (the "McCauley Agreement") and Mr. William J. Lewis
(the Executive Vice President and Chief Credit Officer of Eldorado Bank) (the
"Lewis Agreement") provides that in the event of a reorganization of Eldorado
Bank, the Dellerba, Brown, McCauley and Lewis Agreements will be binding on the
surviving entity in such reorganization. If, however, any of them is terminated
without cause following a reorganization, or any of them elects to terminate his
employment because the surviving entity has taken any of certain actions,
specified in their employment agreements, that adversely affect his compensation
or conditions of employment, he would become entitled to receive a termination
payment equal to one year's base salary then in effect.

         The employment agreement of Mr. Richard Korsgaard (the "Korsgaard
Agreement"), the Executive Vice President of Eldorado Bank, provides that if Mr.
Korsgaard's employment is terminated by Eldorado Bank or any successor to
Eldorado Bank without cause, Mr. Korsgaard will be entitled to receive a
termination payment in an amount equal to the greater of the balance payable
under the Korsgaard Agreement or $125,000. 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 following his reaching age 65 or his death or disability, whichever first
occurs.

         In addition to the foregoing agreements, the Merger Agreement requires
that Eldorado make arrangements with each holder of a stock option to cancel his
or her option(s) prior to the Closing. The holder of each option will be paid a
cash amount equal to the difference between the exercise price per share and
$23.00 multiplied by the number of shares subject to the option. All of
Eldorado's directors and executive officers currently hold options granted under
Eldorado's stock option plans. Assuming the Merger is consummated, the aggregate
consideration that will be received by the directors in cancellation of their
options is approximately $2,458,530 and the aggregate consideration that will be
received by the three executive officers who are not directors in cancellation
of their options is approximately $774,126. See "SHAREHOLDINGS OF CERTAIN
BENEFICIAL OWNERS AND MANAGEMENT."

                                       22
<PAGE>   29
         The Merger Agreement provides that, for a period of six years after the
Effective Time, CSBI shall indemnify and hold harmless present and former
directors and officers of Eldorado or its subsidiaries with respect to matters
existing at or prior to the Effective Time (including with respect to the
transactions contemplated by the Merger Agreement) and CSBI will advance
expenses in connection therewith to the fullest extent then permitted by
applicable law. For a six-year period, CSBI has agreed to use its commercially
reasonable efforts to maintain the existing or similar liability insurance
policies with respect to directors and officers of Eldorado, subject to the
premium costs of such policies not exceeding 200% of the current annual
premiums. CSBI has also agreed to honor the terms and provisions of
indemnification agreements previously entered into between Eldorado and its
officers and directors.

FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

         The following is a summary of the material federal income tax
consequences to the shareholders of Eldorado pursuant to the Merger. The
discussion may not apply to shares received pursuant to the exercise of employee
stock options or otherwise as compensation, to holders of shares who are in
special tax situations (such as insurance companies, dealers in securities,
tax-exempt organizations or non-U.S. persons), or to holders who own shares that
are subject to Section 305(c) or 306 of the Internal Revenue Code. The
discussion is based on the assumptions that: (i) the shares of the stock
constitute capital assets in the hands of the shareholder, and (ii) the
collapsible corporation rules set forth in Section 341 of the Internal Revenue
Code do not apply to Eldorado. The discussion does not address state, local, or
foreign tax considerations.

         THE FEDERAL INCOME TAX CONSEQUENCES SET FORTH BELOW ARE INCLUDED FOR
GENERAL INFORMATIONAL PURPOSES ONLY AND ARE BASED UPON CURRENT LAW. BECAUSE
INDIVIDUAL CIRCUMSTANCES MAY DIFFER, EACH HOLDER OF SHARES SHOULD CONSULT SUCH
HOLDER'S OWN TAX ADVISOR TO DETERMINE THE APPLICABILITY OF THE RULES DISCUSSED
BELOW TO SUCH SHAREHOLDER AND THE PARTICULAR TAX EFFECTS OF THE MERGER,
INCLUDING THE APPLICATION AND EFFECT OF STATE, LOCAL, FOREIGN AND OTHER TAX
LAWS.

         The receipt of cash for shares pursuant to the Merger (including
pursuant to the exercise of dissenters' rights) will be a taxable transaction
for federal income tax purposes (and also may be a taxable transaction under
applicable state, local, foreign and other income tax laws). In general, for
federal income tax purposes, a holder of shares will recognize gain or loss
equal to the difference between his adjusted tax basis in the shares converted
to cash in the Merger and the amount of cash received therefor. Gain or loss
must be determined separately for each block of shares (i.e., shares acquired at
the same cost in a single transaction) converted to cash in the Merger. Such
gain or loss will be long term capital gain or loss if, on the date of the
Merger, such shares were held for more than one year. Amounts received, if any,
with respect to the exercise of dissenters' rights which are or are deemed to be
interest for federal income tax purposes will be taxed as ordinary income.

         The federal tax law significantly limits the deductibility of capital
losses. For corporate taxpayers, capital losses can be deducted only to the
extent of capital gains. For individual taxpayers, capital losses are similarly
deductible up to the extent of capital gains, but may be further deductible up
to a maximum of $3,000 in any one taxable year. Carryovers of unused capital
losses to other taxable years may be permitted in certain circumstances.

         Payments in connection with the Merger may be subject to "backup
withholding" at a 31% rate. Backup withholding will generally be required if the
shareholder (a) fails to furnish his social security number or other taxpayer
identification number ("TIN"), (b) furnishes an incorrect TIN, (c) fails
properly to report interest or dividends or (d) under certain circumstances,
fails to provide a certified statement, signed under penalties of perjury, that
the TIN provided is his correct number and that he is not subject to backup
withholding. Backup withholding is not an additional tax but merely an advance
payment, which may be refunded to the extent it results in an overpayment of
tax. Certain persons generally are entitled to exemption from backup
withholding, including corporations and financial institutions. Certain
penalties apply for failure to furnish correct information and for failure to
include the reportable payments in income. Each shareholder should consult with
his own tax advisor as to his qualification for exemption from withholding and
the procedure for obtaining such exemption.

REGULATORY APPROVALS REQUIRED

         Federal and California law provide that certain acquisition
transactions, such as the Merger, may not be consummated unless approved in
advance by applicable regulatory authorities. The Merger Agreement provides that
CSBI will file and prosecute all applications for approvals that are required to
consummate the Merger, and that Eldorado will cooperate reasonably in that
process.

         The Merger requires the prior approval of the Board of Governors of the
Federal Reserve System (the "FRB") under Section 3(a)(3) of the BHC Act and
implementing regulations. CSBI has informed Eldorado that it has filed a draft
application with the Federal Reserve Bank of San Francisco (which processes such
applications under authority delegated to it by the FRB) on February 19, 1997,
and has further informed Eldorado that a final application (the "Application")
for such approval will be filed with the Reserve Bank in March 1997. The
Application may be determined finally by the Federal Reserve Bank of San
Francisco acting under such delegated authority or may be referred to the FRB in
Washington, D.C. The Application also constitutes an application by CSBI for
authority to exercise the Stock Option Agreement granted to it by Eldorado and
to acquire shares constituting up to approximately 11% of the outstanding Common
Stock upon such exercise. In addition, the Merger requires the prior approval of
the Superintendent of Banks of the State of California under Section 700
et seq. of the California Financial Code. CSBI has advised
Eldorado that it filed an application with the State of California on February
27, 1997.

         Although the Company is not aware of any reason, and CSBI has advised
the Company that CSBI is not aware of any reason, why the requisite approvals of
the Merger would not be granted, there can be no assurance of when or if such
approvals will be obtained or that, if obtained, such approvals would not
include conditions which would be of a type that would relieve CSBI of its
obligation to consummate the Merger. See "THE MERGER AGREEMENT AND THE MERGER --
Conditions to the Merger."

      ELDORADO MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS

         This Proxy Statement includes "forward-looking statements" within the
meaning of Section 21E of the Securities Exchange Act of 1934. Although the
Company believes that the expectations reflected in such forward-looking
statements are reasonable at this time, it can give no assurance that such
expectations will prove to have been correct. Important factors that could cause
actual results to differ materially from the Company's expectations are set
forth herein.

HIGHLIGHTS OF FINANCIAL PERFORMANCE

         Eldorado reported record net earnings of $5.6 million for 1996 compared
to net earnings of $4.5 million and $2.6 million for 1995 and 1994,
respectively. On a per share basis, Eldorado recorded net earnings of $1.43 in
1996 compared to $1.36 in 1995 and $0.84 in 1994. Total assets increased $23.6
million to $406.8 million at December 31, 1996 from $383.2 million at December
31, 1995.

         The increase in 1996 net earnings over 1995 levels was primarily due to
a significantly higher volume of earning assets during the 1996 period as a
result of the acquisition of Mariners Bank in the fourth quarter of 1995, and
secondarily due to lower provisions for loan and lease losses. The increased
earnings from these factors were partially offset by a narrowing in the net
interest margin and higher non-interest expense.

         The increase in 1995 earnings over 1994 levels was due to wider net
interest margins, lower provisions to the allowance for possible credit losses
and lower non-interest expense.

         The two key performance ratios - return on average assets and return on
average equity - were 1.42 percent and 12.49 percent, respectively, for 1996.
The return on average assets for 1995 and 1994 were 1.41 percent and 0.82
percent, respectively. The return on average shareholders' equity for 1995 was
14.33 percent and for 1994 was 8.95 percent.

NET INTEREST INCOME AND MARGIN

         Net interest income is the amount by which the interest earned on loans
and other investments exceeds the interest paid on deposits and other sources of
funds. Net interest income, for the purposes of this analysis, is adjusted to a
"fully taxable equivalent" basis to recognize the yield equivalent of the income
tax savings on certain tax advantaged investments, such as interest on municipal
securities, which make year-to-year comparisons more meaningful. Additionally,
the analysis includes deferred loan fees collected and amortized into interest
income as an adjustment to the yield of such loans.

         Net interest income on a fully taxable equivalent basis increased $2.5
million, or 13 percent, to $21.7 million from $19.2 million in 1995 and compares
to $16.5 million in 1994. Total interest income for 1996 increased $4.2 million
from 1995 levels primarily due to a significantly higher average volume of
earning assets offset by lower yields on earning assets. The increase in the
volume of earning assets was due to the assets acquired in the Mariners Bank
merger in the fourth quarter of 1995. Total interest expense increased $1.7
million due similarly to an increase in the average volume of deposits from the
Mariners Bank merger. A significantly greater increase in the interest on
earnings assets than the increase in the interest expense, therefore, resulted
in higher net interest income of $2.5 million.

         Total interest income for 1995 increased $3.9 million from 1994 levels
primarily due to significantly higher yields on earning assets, and secondarily,
due to a higher volume of earning assets. This increase in earning asset yield
for 1995 was due to a higher average rate earned on variable rate loans and
favorable repricing of a significant portion of the Company's relatively
short-term investment portfolio during the year. Total interest expense
increased $1.2 million due similarly to an increase in the cost of fund rates
and a very slight increase in funding sources. A significantly greater increase
in the yield on earnings assets than the increase in the cost of funds,
therefore, resulted in higher net interest income of $2.1 million while the more
rapid growth in earning assets than funding liabilities further increased net
interest income by $615,000 resulting in a total increase of $2.7 million.

                                       26
<PAGE>   33
         The net interest margin narrowed to 6.30 percent in 1996 from 6.75
percent in 1995 and was 5.94 percent in 1994. The yield on earning assets in
1996 decreased 31 basis points while the cost of interest-bearing liabilities
increased 23 basis points. This narrowing of the net interest margin was largely
offset by a larger percentage of noninterest-bearing liabilities used to fund
earning assets, resulting in the total cost of funds increasing only 13 basis
points. The yield on earning assets in 1995 increased 117 basis points while the
cost of interest-bearing liabilities increased 70 basis points. The net interest
margin was widened further by a larger percentage of noninterest-bearing
liabilities funding earning assets, resulting in the total cost of funds
increasing only 38 basis points.

PROVISION FOR POSSIBLE CREDIT LOSSES

         The 1996 provision for loan and lease losses was $153,000 compared to
$756,000 in 1995 and $2.0 million in 1994. Net loans and leases charged totaled
$1.7 million in 1996 compared to $872,000 and $1.4 million in 1995 and 1994,
respectively. The increase in net charge-offs in 1996 was largely due to a
charge off of $1.5 million on one particular loan and secondarily due to lower
recoveries of loans previously charged off. Specific allowances had been
established in the loans charged off in 1996, therefore, no additional
provisions were required to maintain the adequacy of the allowance for possible
credit losses.

         Total delinquent loans were 2.8 percent of total loans at year-end 1996
compared to 4.7 percent and 3.2 percent at year-ends 1995 and 1994,
respectively. Non-accrual loans at year-end 1996, which are included in the
delinquency figure, were $4.7 million, consisting primarily of commercial real
estate loans, compared to $6.4 million a year earlier and $3.2 million at year
end 1994. The decrease in non-accrual loans, and the corresponding decrease in
the delinquency ratio, is primarily due to the large charge-off and continued
resolution of problem credits.

         The following table shows certain ratios relating to the Company's loan
loss experience, allowance and provision for possible credit losses for and at
the end of the year indicated:

     performing loans                              100.24%               101.08%
</TABLE>

         The allowance for possible credit losses decreased to $4.7 million at
December 31, 1996 from $6.3 million at year-end 1995, resulting in an allowance
for possible credit losses of 2.1 percent of total loans and leases compared to
2.7 percent at year-end 1995. The allowance for possible credit losses is
established based upon an analysis providing specific allowances for loans that
management has identified to have potential loss and general allowances for
unidentified losses inherent in the portfolio. The general allowance is
determined by segmenting the portfolio by risk rating and loan type with
allowances established based upon historical losses in each portfolio segment.
Additionally, consideration is given to loan type concentrations in the
portfolio and the current and anticipated economic environment. The reduction in
the allowance as a percent of loans despite the increase in charge-offs during
1996 is consistent with the charge off of loans having specific allowances in
the adequacy determination methodology.

OTHER INCOME

         Other income totaled $4.4 million in 1996 compared to $4.0 million and
$4.8 million in 1995 and 1994, respectively. Service charges on deposit accounts
increased in 1996 as compared to the prior year due to a higher volume of
accounts. Bankcard discounts declined to $168,000 for 1996 from $405,000 for
1995 due to management's decision to outsource the function in which revenues
are now received net of costs. Additionally, other miscellaneous income was
higher in 1996 compared to 1995.

OPERATING EXPENSE

         Operating expenses increased in 1996 to $16.4 million from $14.8
million in 1995. Salaries increased to $5.4 million in 1996 from $4.6 million in
1995 primarily due to the addition of employees resulting from the Mariners Bank
acquisition. Employee benefits declined in 1996 to $2.1 million from $2.4
million the prior year due to lower levels of incentive compensation. Occupancy
expense increased to $1.7 million from $1.4 million due to the additional
branches from the Mariners Bank acquisition and increases in the rental expense
in several of the other facilities, offset by the elimination of the expense
from the two branches closed and consolidated into the three former Mariners
Bank branches. Furniture and equipment expense likewise increased from $900,000
to $1.1 million. Other miscellaneous expenses increased to $6.0 million in 1996
from $5.1 million in 1995.

         Operating expenses declined in 1995 to $14.8 from $14.9 million in
1994. Salaries increased slightly to $4.6 million during the 1995 year compared
to $4.5 million in 1994, reflecting the addition of several new departments and
product offerings (accounts receivable financing and international banking) in
addition to the acquisition of Mariners Bank in October 1995. Employee benefits
increased to $2.4 million in 1995 compared to $1.8 million in 1994 primarily due
to higher levels of incentive compensation. Occupancy expense decreased due to
the consolidation of administrative offices and the $264,000 recapture of a
reserve for remaining net costs of a preexisting lease put back into use for
Company operations.

ASSET GROWTH AND MIX

         Average total assets during 1996 were $392 million, an increase of $73
million, or 23 percent, over 1995 average total assets of $318 million. Average
loans and leases comprised 55 percent of average total assets in 1996 compared
to 58 percent in 1995. The average composition of the loan portfolio was 43
percent commercial loans, 36 percent real estate loans, 8 percent interim
construction financing, and 13 percent installment loans. The 1995 loan mix was
41 percent commercial, 43 percent real estate, 3 percent interim construction,
and 12 percent installment. Average direct lease financing was less than 1
percent of average total assets in 1996 and 1995. Management has emphasized a
strategy to better diversify the Company's loan portfolio in 1996 by increasing
relationship commercial business with less emphasis on growth in real estate
loans. The Company retained nearly all of its new SBA loan production during
1996 and 1995, whereas in past years, SBA loan production had been sold.

         Securities available-for-sale and held-to-maturity were 26 percent of
average total assets in 1996 compared to 27 percent in 1995. At year end 1996,
92 percent of the investment securities portfolio was classified as available
for sale. Average federal funds sold were 5 percent of average total assets in
1995 and 1994. Higher reserve balances were required to be maintained at the
Federal Reserve Bank due to the growth in demand deposit balances.

         Other real estate owned ("OREO") averaged $1.0 million in 1996 compared
to $2.0 million in 1995. At December 31, 1995, OREO totaled $394,000, compared
to $2.0 million a year earlier.

                                       28
<PAGE>   35
DEPOSIT GROWTH AND MIX

         During 1996, average total deposits were $341 million, an increase of
$62 million over average deposits of $279 million in 1995. Interest-bearing
deposits represented 70 percent of average total deposits in 1996 and 1995. The
average composition of deposits in 1996 was 30 percent demand deposits, 45
percent savings and money market deposits and 25 percent time deposits. This
compares to a 1995 deposit mix of 30 percent demand, 51 percent savings and
money market and 19 percent time deposits.

CAPITAL MANAGEMENT

         During 1996, shareholders' equity averaged $44.7 million or 11.4
percent of average total assets compared to $31.4 million or 9.9 percent of
average total assets in 1995. On December 31, 1996 and 1995, shareholders'
equity was 11.5 percent and 11.1 percent of total assets, respectively. The
increase in the average capital ratio for 1996 was due to growth in retained
earnings and the issuance of common shares in partial consideration of the
Mariners Bancorp acquisition. The Company declared and paid cash dividends of
$0.37 per share in 1996 totaling $1.4 million. In 1995, dividends of $0.32 per
share totaling $960,000 were declared and paid.

         Risk-based capital guidelines issued by the Board of Governors of the
Federal Reserve System ("FRB") for bank holding companies establish an
analytical framework that makes regulatory capital requirements sensitive to the
risk profile of a banking organization's balance sheet. The guidelines provide
for risk-based capital standards requiring banking institutions to have minimum
total regulatory capital equivalent to 8 percent of assets and off-balance sheet
exposures, weighted by risk. At least half of the required capital must be Tier
1 capital, which consists of core capital elements including common
stockholders' equity and retained earnings. At December 31, 1996, the Company
exceeded the Tier 1 risk-based capital requirements with a ratio of 15.47
percent and a total risk-based capital ratio of 16.73 percent.

         To supplement the risk-based capital guidelines, the FRB established a
minimum leverage ratio guideline of 3 percent. The leverage ratio consists of
Tier 1 capital divided by total assets (excluding intangibles and other items
which were deducted to arrive at Tier 1 capital). At December 31, 1996, the
Company's leverage ratio was 9.99 percent.

         Under the Federal Deposit Insurance Corporation Improvement Act of
1991, a "well capitalized" bank must have a Tier 1 risk-based capital ratio of
at least 6 percent, a combined Tier 1 and Tier 2 ratio of at least 10 percent
and a leverage ratio of at least 5 percent (and not be subject to a capital
directive order). At December 31, 1996, the Bank had a Tier 1 risk-based capital
ratio of 14.30 percent, a combined Tier 1 and Tier 2 ratio of 15.56 percent and
a leverage ratio of 9.53 percent.

LIQUIDITY AND INTEREST SENSITIVITY

         The primary objectives of the Company's asset and liability management
strategy are the maintenance of adequate liquidity and effective management of
interest rate risk. Liquidity management attempts to match sources and uses of
funds in order to meet the requirements of customers for loans and deposit
withdrawals. Interest rate risk management seeks to maintain a stable growth of
income and manage the risk associated with changes in interest rates.

         The Company maintains short-term sources of funds to meet periodic
increases in loan demand and deposit withdrawals and maturities. At December 31,
1996, the principal source of asset liquidity consisted of $34.1 million in cash
and demand balances due from banks and federal funds sold of $28.4 million
totaling $62.5 million, compared to a total of $41.9 million in these same
assets a year earlier. Other sources included $95.9 million in securities
available-for-sale.

         The Company has an established facility to borrow federal funds from
other banks in excess of $24 million. Additionally, there is a strong secondary
market providing for the sale of the government-guaranteed portion of the
Company's SBA loans that total approximately $10.0 million at year-end 1996.
Also, in the past the Company has issued

                                       29
<PAGE>   36
commercial paper to generate liquidity at the holding company level, however,
during 1996 and 1995, the Company sold no commercial paper. Furthermore,
substantially all of the installment loans and leases require regular
installment payments, providing a steady flow of cash funds.

         The Company manages 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. The Company does not utilize any interest rate swaps
or other financial derivatives to alter its interest rate risk profile.

         One way to measure the impact that future change 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 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 interest 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 following table shows the Company's
assets and liabilities and the cumulative gap for the periods shown:

<TABLE>

</TABLE>

         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 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 various
interest rate environments.

                         INFORMATION REGARDING ELDORADO

GENERAL

   The Company

         Eldorado Bancorp ("Eldorado" or the "Company") is a California
corporation organized in January 1981 and is registered as a bank holding
company under the Bank Holding Company Act of 1956, as amended. The Company's
primary asset is the capital stock of Eldorado Bank ("Eldorado Bank" or the
"Bank"), and the business of the Bank is carried on as a wholly-owned subsidiary
of the Company. The Company has no subsidiary or affiliated business other than
the Bank.

         Unless otherwise indicated, all information herein is as of December
31, 1996.

   The Bank

         The Bank was incorporated under the laws of the State of California on
February 3, 1972, and was licensed by the California State Banking Department
and commenced operations as a California state-chartered bank on May 1, 1972.
The Bank's accounts are insured by the Federal Deposit Insurance Corporation
("FDIC"). The Bank is not a member of the Federal Reserve System. The Bank
currently operates a total of twelve banking offices in Southern California.

         The Bank's original banking and its headquarters office is located in
Tustin, California, approximately 35 miles south of Los Angeles. The Bank also
operates one banking office in Laguna Hills, California, a residential community
in southern Orange County approximately 50 miles south of Los Angeles, one
banking office in San Bernardino, which is located approximately 60 miles east
of Los Angeles, and one banking office each in Indio and Palm Desert, which are
located approximately 115 miles east of Los Angeles. The Bank's expansion into
the Indio and Palm Desert area was accomplished through the merger of the Bank
of Indio with and into the Bank in April 1982. The Bank's expansion into San
Bernardino occurred with the acquisition of American Security Bank in August
1980. In March 1988 the Company acquired American Merchant Bank, which was then
merged into the Bank in May 1988. This further broadened the Bank's base in
Orange County with the addition of offices in the cities of Orange, Huntington
Beach and Newport Beach. In 1992, the Bank relocated the Newport Beach branch to
a nearby office in Irvine. The Bank further expanded into South Orange County
with the acquisition of Bank of San Clemente in October 1991. This acquisition
added two branches in San Clemente, which is located approximately 65 miles
south of Los Angeles. On October 20, 1995, the bank acquired all the voting
shares of Mariners Bancorp. Mariners Bancorp and its wholly-owned subsidiary,
Mariners Bank, were thereafter merged with and into Eldorado Bank. Mariners Bank
was headquartered in San Clemente, California and operated its head banking
office in that city and two branch banking offices in San Juan Capistrano and
Monarch Beach. The Bank consolidated its two branch banking offices in San
Clemente into the former Mariners Bank branch banking offices. In September
1996, the bank expanded into Los Angeles County with the opening of a de novo
branch banking office in the Long Beach Community Hospital in the City of Long
Beach, which is approximately 30 miles south of Los Angeles.

   Services Provided by Eldorado Bank

         The Bank's organization and operations have been designed to meet the
banking needs of individuals and small-to medium-sized businesses located in the
areas of Orange, Los Angeles, San Bernardino and Riverside counties of
California, in which the Bank conducts its operations. The Bank's commitment to
provide convenient banking and a complete range of personalized services is
evidenced by early evening hours and Saturday banking hours at some locations,
drive-up facilities and automatic teller machines at its banking offices,
innovative professional programs, and departmentalized service centers.

         The Bank offers a full range of commercial banking services, including
the acceptance of checking and savings deposits, the making of commercial loans,
various types of real estate loans and consumer loans, Small Business
Administration-guaranteed loans, corporate cash management services,
international banking services and the provision of safe deposit, collection,
travelers' checks, notary public and other customary non-deposit banking
services. The Bank also

                                       31
<PAGE>   38
provides lease financing of automobiles and other equipment. The Bank is a
card-issuing bank for MasterCard and Visa and merchant depository for MasterCard
and Visa drafts, enabling merchants to deposit both types of drafts with the
Bank. The Bank also offers special services to senior citizens, who constitute
an important segment of the population in the Bank's service area.

COMPETITION

         The Bank faces substantial competition for deposits and loans
throughout its market areas. The primary factors in competing for deposits are
interest rates, personalized services, the quality and range of financial
services, convenience of office locations and office hours. Competition for
deposits comes primarily from other commercial banks, savings institutions,
credit unions, money market funds and other investment alternatives. The primary
factors in competing for loans are interest rates, loan origination fees, the
quality and range of lending services and personalized services. Competition for
loans comes primarily from other commercial banks, savings institutions,
mortgage banking firms, credit unions and other financial intermediaries. The
Bank faces competition for deposits and loans throughout its market areas not
only from local institutions but also from out-of-state financial intermediaries
which have opened loan production offices or which solicit deposits in its
market areas. Many of the financial intermediaries operating in the Bank's
market areas offer certain services, such as trust, investment and international
banking services, which the Bank does not offer directly. Additionally, banks
with larger capitalization and financial intermediaries not subject to bank
regulatory restrictions have larger lending limits and are thereby able to serve
the needs of larger customers.

         The Bank competes principally on the basis of personalized attention
and special services which it provides its customers, principally individuals
and small to medium size businesses and by promotional activities of the Bank's
officers, directors, employees and shareholders. Most of the Bank's offices
offer extended weekday banking hours and some branches offer Saturday banking
hours. The Bank also operates drive-up banking facilities at seven of its
branches and provides a variety of personalized services. In addition, the Bank
operates 24-hour automatic teller machines (ATM) at nine of its locations and is
a member of Instant Teller network and Plus System network, which link bank ATMs
nationwide. The Bank has also increased the range of services which it provides
in order to meet the expanding banking requirements of its customers. In 1985,
the Bank established a Small Business Administration department. The opening of
the de novo branch banking office within the Long Beach Community Hospital
reflects a current strategy of targeting captive markets, e.g. medical
professionals, with relatively low-cost facilities as compared to a traditional
branch banking office. The Long Beach office is a full-service branch banking
office contained in approximately 400 square feet and staffed by a full-time
equivalent of three personnel. The branch offers an automated teller machine and
night drop services.

         For customers whose loan demands exceeds the Bank's lending limits, the
Bank has attempted in the past to arrange for such loans on a participation
basis with correspondent banks. The Bank also assists customers requiring other
services, such as trust services not offered by the Bank, by obtaining such
services from trust companies and correspondent banks.

Ordinarily, the accrual of interest ceases when no payment of interest or
principal has been made for 90 days or if the Bank has reason to believe that
continued payment of interest and principal is unlikely. Accrued interest, if
any, is reversed at the time such loans are placed on nonaccrual status. If
these loans had been current throughout their terms, interest and fees on loans
would have increased by approximately $343,000, $172,000, $144,000, $108,000,
and $103,000 for 1996, 1995, 1994, 1993, and 1992 respectively.

</TABLE>

         Troubled debt restructurings consist primarily of loans for which the
interest rate was reduced or the payment provisions were modified because of the
inability of the borrower to service the obligation under the original terms of
the agreements. Income is accrued at the lower effective rate provided the
borrower is current under the revised terms and conditions of the agreements.
Under the original terms of the restructured loans, interest earned would have
totaled approximately $496,000 for the year ended December 31, 1996. Under the
restructured terms, recorded interest income amounted to $316,000 for the year
ended December 31, 1996.

Risk Elements. Potential Problem Loans. Potential problem loans are accounted
for under the provisions of the Financial Accounting Standards Board's
Statements of Financial Accounting Standards ("SFAS") No. 114, "Accounting by
Creditors for Impairment of a Loan," as amended by SFAS No. 118, "Accounting by
Creditors for Impairment of a Loan - Income Recognition and Disclosures." SFAS
114 requires loans to be measured for impairment when it is probable that all
amounts, including principal and interest, will not be collected in accordance
with the contractual terms of the loan agreement. Generally, the Bank evaluates
a loan for impairment when it is placed on nonaccrual status At December 31,
1996, total nonaccrual loans of $3,425,000 were considered impaired in
accordance with SFAS 114. The following is a summary of impaired loans and the
related allowance for possible credit losses at December 31, 1996:

      The allowance for possible credit losses is established by a provision for
possible credit losses charged against current period income. Loans and leases
are charged against the allowance for possible credit losses when management
believes that the collectibility of principal is unlikely. The allowance is an
amount that management believes will be adequate to absorb losses inherent in
existing loans, leases and commitments to extend credit, based on the
evaluations of the collectibility and prior loss experience of loans, leases and
commitments to extend credit. The evaluations take into consideration such
factors as changes in the nature and volume of the portfolio, overall portfolio
quality; loan concentrations; specific problem loans, leases and commitments;
and current and anticipated economic conditions that may affect the borrowers'
ability to pay.

      Management believes that the allowance for possible credit losses is
adequate. While management uses available information to recognize losses on
loans and leases, future additions to the allowance may be necessary based on
changes in economic conditions. In addition, both federal and state regulators,
as an integral part of their examination process, periodically review the Bank's
allowance for possible credit losses and may recommend additions based upon
their evaluation of the portfolio at the time of their examination.

      The risk of nonpayment of loans is an inherent feature of the banking
business. That risk varies with the type and purpose of the loan, the collateral
which is utilized to secure payment, and ultimately, the creditworthiness of the
borrower. In order to minimize this credit risk, the Bank has established
lending limits for each of its officers having lending authority, in each case
based upon the officer's experience level and prior performance. Whenever a
proposed loan by itself, or when aggregated with outstanding extensions of
credit to the same borrower, exceeds the officer's lending limits, the loan must
be approved by the Bank's Chairman, President or Executive Vice President/Chief
Credit Officer or by the Bank's loan committee, depending upon the dollar amount
involved. The loan committee is comprised of two directors and four members of
the Bank's senior management. In addition, each loan officer has primary
responsibilities to conduct credit documentation reviews of all loans made by
that officer.

      Furthermore, the Bank also maintains a program of periodic review of all
existing loans and employs a specialist who reviews loans over a certain dollar
amount and grades these loans based upon the dollar amount and credit worthiness
using a grading system. Loans are graded from "one" to "eight" depending on
credit quality, with "grade one" representing a prime loan with a definite and
reliable repayment program based upon liquid collateral with adequate margin or
supported by a strong up-to-date financial statement. Problem or substandard
loans identified in the review process are scheduled for remedial action, and
where appropriate, allowances are established for such loans. Periodically, an
outside loan review consultant further reviews loans for credit quality.
Additionally, the Bank is examined regularly by the FDIC and California State
Banking Department at which time a further review of loans is conducted.

Allocation of Allowance for Possible Credit Losses. The Bank has allocated the
allowance for credit losses according to the amount deemed to be reasonably
necessary to provide for the possibility of losses being incurred within the
categories of loans set forth in the following table:

    Other Real Estate Owned

      The Bank sometimes acquires real estate properties in satisfaction of loan
receivables through foreclosure or other means. The Bank accounts for these
properties pursuant to Statement of Position 92-3, "Accounting for Foreclosed
Assets," which presumes that foreclosed assets are held-for-sale and not for the
production of income. Accordingly, the real estate properties are carried at
fair value less estimated costs to sell. The Bank determines fair value based
upon appraisals near the date of foreclosure. These appraisals are periodically
updated and subsequent write-downs of value may be recognized in the event of
declining fair values. On December 31, 1996 the Bank had other real estate owned
of approximately $394,000 consisting primarily of an unimproved commercial lot.

SUPERVISION AND REGULATION

    The Company

      The Company, as a registered bank holding company, is subject to
regulation under the BHC Act. The Company is required to file with the FRB
quarterly and annual reports and such additional information as the FRB may
require pursuant to the BHC Act. The FRB may conduct examinations of the Company
and its subsidiaries.

      The FRB may require that the Company terminate an activity or control of
certain subsidiaries when the FRB believes the activity or control constitutes a
serious risk to the financial safety, soundness or stability of any of its
banking subsidiaries and is inconsistent with sound banking principles or the
purposes of the BHC Act or the Financial Institutions Supervisory Act of 1966,
as amended. The FRB also has the authority to regulate provisions of certain
bank holding company debt, including authority to impose interest ceilings and
reserve requirements on such debt. Under certain circumstances, the Company must
file a written notice and obtain approval from the FRB prior to purchasing or
redeeming its equity securities.

      Under the BHC Act and regulations adopted by the FRB, a bank holding
company and its non-banking subsidiaries are prohibited from requiring certain
tie-in arrangements in connection with any extension of credit, lease or sale of
property or furnishing of services. Further, the Company is required by the FRB
to maintain certain levels of capital. The FRB's risk-based capital guidelines
establish a minimum level of qualifying total capital to risk-weighted assets of
8.00% (of which at least 4.00% should be in the form of Tier 1 Capital). The
regulations set forth minimum requirements, and the FRB has reserved the right
to require that companies maintain higher capital ratios. As of December 31,
1996 the Company had a ratio of qualifying total capital to risk-weighted assets
of 16.73%, of which 15.47% was in the form of Tier 1 Capital. Additionally, the
FRB established a minimum leverage ratio of 3%. At December 31, 1996, the
Company's leverage ratio was 9.99%. For a more complete description of the FRB's
risk-based and leverage capital guidelines, see "-- Supervision and Regulation -
Capital Adequacy Guidelines."

      The Company is required to obtain the prior approval of the FRB for the
acquisition of more than 5% of the outstanding shares of any class of voting
securities or substantially all of the assets of any bank or bank holding
company. Prior approval of the FRB is also required for the merger or
consolidation of the Company with another bank holding company.

      The Company is prohibited by the BHC Act, except in certain statutorily
prescribed instances, from acquiring direct or indirect ownership or control of
more than 5% of the outstanding voting shares of any company that is not a bank
or bank holding company and from engaging directly or indirectly in activities
other than those of banking, managing or controlling banks or furnishing
services to its subsidiaries. However, the Company may, subject to the prior
approval of the FRB, engage in, or acquire shares of companies engaged in,
activities that are deemed by the FRB to be so closely related to banking or
managing or controlling banks as to be a proper incident thereto. In making any
such determination, the FRB is required to consider whether the performance of
such activities by the Company or an affiliate can reasonably be expected to


                                       41
<PAGE>   48
produce benefits to the public, such as greater convenience, increased
competition or gains in efficiency, that outweigh possible adverse effects, such
as undue concentration of resources, decreased or unfair competition, conflicts
of interest or unsound banking practices. The FRB is also empowered to
differentiate between activities commenced de novo and activities commenced by
acquisition, in whole or in part, of a going concern and is generally prohibited
from approving an application by a bank holding company to acquire voting shares
of any commercial bank in another state unless such acquisition is specifically
authorized by the laws of such other state.

      The Company is also a bank holding company within the meaning of Section
3700 of the California Financial Code. As such the Company and its subsidiary
are subject to examination by, and may be required to file reports with, the
California State Banking Department.

      Finally, the Company is subject to the periodic reporting requirements of
the Securities Exchange Act of 1934, as amended, including but not limited to,
filing annual, quarterly, and other current reports with the Securities and
Exchange Commission.

    The Bank

      The Bank, as a California state-chartered bank, is subject to primary
supervision, periodic examination and regulation by the California
Superintendent of Banks (the "Superintendent") and the FDIC. If, as a result of
an examination of a bank, the FDIC should determine that the financial
condition, capital resources, asset quality, earnings prospects, management,
liquidity, or other aspects of the Bank's operations are unsatisfactory or that
the Bank or its management is violating or has violated any law or regulation,
various remedies are available to the FDIC. Such remedies include the power to
enjoin "unsafe and unsound" practices, to require affirmative action to correct
any conditions resulting from any violation or practice, to issue an
administrative order that can be judicially enforced, to direct an increase in
capital, to restrict the growth of the bank, to assess civil monetary penalties,
to remove officers and directors and ultimately to terminate a bank's deposit
insurance, which for a California state-chartered bank would result in a
revocation of the bank's charter. The Superintendent has many of the same
remedial powers.

      The Bank is insured by the FDIC, which currently insures deposits of each
member bank to a maximum of $100,000 per depositor. For this protection, each
bank pays a quarterly statutory assessment and is subject to the rules and
regulations of the FDIC. Although the Bank is not a member of the Federal
Reserve System, it is nevertheless subject to certain regulations of the FRB.

      Various requirements and restrictions under the laws of the State of
California and the United States affect the operations of the Bank. See "--
Effect of Governmental Policies and Recent Legislation." State and federal
statutes and regulations relate to many aspects of the Bank's operations,
including reserves against deposits, interest rates payable on deposits, loans,
investments, mergers and acquisitions, borrowings, dividends, locations of
branch offices and capital requirements.

      The FDIC's statement of policy on risk-based capital requires that banks
maintain a ratio of qualifying total capital to risk-weighted assets of not less
than 8.00% (at least 4.00% of which should be in the form of Tier 1 Capital).
The regulations set forth minimum requirements, and the FDIC has reserved the
right to require that banks maintain higher capital ratios. Among other rights,
the FDIC's regulations provide that capital requirements may be enforced by the
issuance of a directive. As of December 31, 1996, the Bank had a ratio of total
qualifying capital to risk-weighted assets of 15.56%, of which 14.30% was in the
form of Tier 1 Capital. The FDIC's capital adequacy regulations also require
that banks maintain a minimum leverage standard of 3% Tier 1 Capital to total
assets for the most highly rated banks. The regulations set forth minimum
requirements, and the FDIC has reserved the right to require that banks maintain
higher ratios. As of December 31, 1996, the Bank's leverage ratio was 9.53%. For
a more complete description of the FDIC's risk-based capital regulations, see
"-- Supervision and Regulation - Capital Adequacy Guidelines."

    Capital Adequacy Guidelines

      The FRB and the FDIC have issued guidelines to implement risk-based
capital requirements. The guidelines establish a systematic analytical framework
that makes regulatory capital requirements more sensitive to differences in risk
profiles among banking organizations, takes off-balance sheet items into account
in assuring capital adequacy, and minimizes disincentives to holding liquid,
low-risk assets. Under these guidelines, assets and credit equivalent amounts of
off-balance sheet items, such as letters of credit and outstanding loan
commitments are assigned to one of several risk categories, which range from 0%
for risk-free assets, such as cash and certain U.S. government securities, to
100% for relatively high-risk assets, such as loans and investments in fixed
assets, premises and other real estate owned. The aggregated dollar amount of
each category is then multiplied by the risk weight associated with that
category. The resulting weighted values from each of the risk categories are
then added together to determine the total risk-weighted assets. The guidelines
require a minimum ratio of qualifying total capital to risk-weighted assets of
8.00% (of which at least 4.00% must consist of Tier 1 Capital).

      Tier 1 Capital consists primarily of common stock, related surplus,
retained earnings and certain perpetual preferred stocks, less goodwill.
Allowances for loan losses qualify only as supplementary capital and then only
to the extent of 1.25% of total risk-weighted assets. Other elements of
supplementary capital, which is limited overall to 100% of Tier 1 Capital,
include qualifying perpetual preferred stock, hybrid capital instruments and
mandatory convertible debt securities, and subordinated debt and
intermediate-term preferred stock.

      Effective December 31, 1990, the FRB and the FDIC adopted a minimum
leverage ratio of Tier 1 Capital to total assets of 3% for the highest-ranked
banks. The leverage ratio is only a minimum. Institutions experiencing or
anticipating significant growth or those with other than minimum risk profiles
will be expected to maintain capital well above the minimum levels.

    Federal Deposit Insurance Corporation Improvement Act of 1991

      On December 19, 1991, the Federal Deposit Insurance Corporation
Improvement Act of 1991 ("FDICIA") was enacted into law. Set forth below is a
summary of certain provisions of that law and actual and proposed enabling
regulations.

Prompt Corrective Action. The prompt corrective action provisions of FDICIA
provide for certain mandatory and discretionary actions by the appropriate
federal banking regulatory agency, determined mostly by an institution's ranking
within the following five capital measures: "well capitalized," "adequately
capitalized," "undercapitalized," "significantly undercapitalized" and
"critically undercapitalized." The federal banking agencies have promulgated
substantially uniform regulations implementing these provisions of FDICIA,
effective December 19, 1992. Under these regulations, a bank would be deemed (i)
"well capitalized" if it has (a) a total risk-based capital ratio of 10% or
greater, (b) a Tier 1 risk-based capital ratio of 6% or greater, (c) a leverage
ratio of 5% or greater and (d) is not subject to any written agreement, order or
capital directive to meet and maintain a specific capital level; (ii)
"adequately capitalized" if it has (a) a total risk-based capital ratio of 8% or
greater, (b) a Tier 1 risk-based capital ratio of 4% or greater, (c) a leverage
ratio of 4% or greater (or a leverage ratio of 3% or greater for banks with a
CAMEL 1 composite rating) and (d) does not meet the definition of a well
capitalized bank; (iii) "undercapitalized" if it has (a) a total risk-based
capital ratio of less than 8%, (b) a Tier 1 risk-based capital ratio of less
than 4% or (c) a leverage ratio of less than 4% (or a leverage ratio of less
than 3% for banks with a CAMEL 1 composite rating); (iv) "significantly
undercapitalized" if it has (a) a total risk-based capital ratio of less than
6%, (b) a Tier 1 risk-based capital ratio of less than 3% or (c) a leverage
ratio of less than 3%; and (v) "critically


                                       43
<PAGE>   50
undercapitalized" if it has a ratio of tangible equity to total assets equal to
or less than 2%. The federal banking agencies may also, under certain
circumstances, reclassify a "well capitalized" institution as "adequately
capitalized" or require an "adequately capitalized" or "undercapitalized"
institution to comply with supervisory actions as if it were in the next lower
category. The agencies may take such action upon a showing that an institution
is in an unsafe or unsound condition or is engaged in an unsafe or unsound
practice (including failure to correct certain unsatisfactory examination
ratings).

      Insured institutions are subject to certain incremental supervisory
restraints based on their actual or imputed ranking within the five capital
categories. All institutions are prohibited from making a capital distribution
or paying management fees to controlling persons if, after such transaction, the
institution would be undercapitalized. All undercapitalized institutions,
including significantly and critically undercapitalized institutions, are
required to file a capital restoration plan with their appropriate federal
banking regulator, undergo close monitoring of the condition of the bank and are
subject to restrictions on operations, including prohibitions on asset growth,
branching, acquisitions and engaging in new lines of business, without prior
regulatory approval. Also, Federal Reserve Bank advances to such institutions
(and institutions with a CAMEL 5 composite rating) for more than 60 days will be
generally restricted. In order to receive regulatory approval of the required
capital restoration plan, a company controlling such undercapitalized
institution will be required to guarantee its subsidiary's compliance with the
capital restoration plan, up to an amount equal to the lesser of 5% of the
subsidiary bank's assets or the amount of the capital deficiency when the bank
first failed to comply with such plan.

      Significantly or critically undercapitalized institutions and
undercapitalized institutions which fail to submit or implement an acceptable
capital restoration plan are subject to one or more of the following additional
regulatory actions (one or more of which is mandatory): (i) forced sale of
shares and, where grounds exist for conservatorship or receivership, a forced
merger; (ii) restrictions on affiliate transactions; (iii) limitations on
interest rates paid on deposits; (iv) restrictions on asset growth or required
shrinkage; (v) alteration or curtailment of activities determined by the
regulators to pose excessive risk to the institution; (vi) replacement of
directors or senior executive officers, subject to certain grandfather
provisions; (vii) prohibition on acceptance of correspondent bank deposits;
(viii) restrictions on capital distributions by the holding companies of such
institutions; (ix) forced divestiture of an institution's subsidiaries or
divestiture by a bank holding company of an institution or a financially
troubled non-banking affiliate; or (x) other actions as determined by the
regulators. Additionally, such institutions may not pay bonuses or provide
raises to senior officers without the prior written approval of the appropriate
federal regulator. The applicable federal regulator is required to impose a
forced sale of shares or a merger, restrictions on affiliate transactions and
restrictions on rates paid on deposits, unless it determines that such actions
would not further an institution's capital improvement.

      FDICIA and its enabling regulations provide for further restrictions
applicable solely to critically undercapitalized institutions, including at a
minimum, prohibitions on the following activities without the prior written
consent of the FDIC: (i) entering into material transactions other than in the
usual course of business; (ii) extending credit for highly leveraged
transactions; (iii) amending an institution's charter or bylaws; (iv) making a
material change in accounting methods; (v) engaging in certain transactions with
affiliates; (vi) paying excessive compensation or bonuses; or (vii) paying rates
on new or renewed liabilities significantly in excess or market rates.
Additionally, 60 days after becoming critically undercapitalized, an institution
may not make payment of interest or principal on subordinated debt without the
permission of the FDIC and its primary federal regulator.

      FDICIA requires the appointment of a receiver or conservator no later than
90 days after an institution becomes critically undercapitalized, unless an
institution's primary regulator and the FDIC determine that another action would
result in a smaller loss to the deposit insurance fund. If such an institution
is not placed into receivership and remains critically undercapitalized, on
average, during the calendar quarter beginning 270 days after it first became
critically undercapitalized, it would generally be required to be placed into
receivership. FDICIA would not require such action only if the institution
exhibits certain specific signs of recovery and receives a certification of
viability from the head of its primary regulatory agency and the Chairperson of
the FDIC.

Limitations on Activities of Insured State Banks. FDICIA provides generally that
insured state banks and their subsidiaries may only engage as principal in types
of activities that are permissible for national banks. FDICIA provides for a
general exception (other than for insurance underwriting activities) if a bank
is in compliance with applicable capital standards and the FDIC determines that
an activity would pose no significant risk to the deposit insurance fund. Rules
published by the


                                       44
<PAGE>   51
FDIC set forth certain types of activities that the FDIC deem, in advance, to
not represent such a risk, including certain credit guarantee activities,
activities closely related to banking, and certain securities underwriting
activities conducted through subsidiaries. Certain exceptions expressly provided
by FDICIA to the imposition of national bank standards in the area of insurance
underwriting activities include, under certain circumstances, underwriting of
title insurance, savings bank life insurance (for banks in certain states) and
continuation of insurance provided prior to enactment of FDICIA if such
insurance was reinsured by the Federal Crop Insurance Corporation. Also, state
banks may, under certain circumstances, continue to offer and provide types of
insurance to residents and businesses of a state if such insurance was offered
within that state prior to FDICIA.

      Other FDIC rules flatly prohibit direct investment in commercial ventures
(non-financial services) by state banks. In cases where activities of state
banks require the prior consent of the FDIC, the proposed regulations provide
that a bank remain adequately capitalized after deducting from capital its
investment in a subsidiary or department in which such activities would be
conducted. The FDIC's consent would be further conditioned on conducting such
activities in an independent "bona fide subsidiary" or an independent
"department," which would subject the bank to affiliate transaction fairness
rules and limits on total lending exposure to such units.

      Other provisions of FDICIA provide that insured state banks may not,
directly or indirectly, acquire or retain any equity investment (including
common and preferred stock, partnership interests and most equity interests in
real estate) of a type, or in an amount, that is not permissible for national
banks. Exceptions provided by FDICIA to imposition of national bank standards
include investments in majority owned subsidiaries which conduct permissible
activities and in other depository institutions (with certain parameters), and
limited investments in qualified (low income) housing projects and in insurance
companies which provide director's, officer's and trustee's liability coverage
or bankers' blanket bond group coverage for other insured depository
institutions (or companies which reinsure such policies). FDICIA also permits,
under certain circumstances, the retention by state banks of exchange-listed
stock and shares of registered investment companies held prior to enactment of
FDICIA.

Standards for Safety and Soundness. FDICIA required each federal banking agency
to promulgate regulations setting forth certain safety and soundness standards
for insured depository institutions and, in some cases, their holding companies
in three main areas: (i) operations and management (including information
systems, internal controls and audits, loan documentation, credit underwriting,
interest rate risk and asset growth); (ii) asset quality and earnings levels;
and (iii) employee compensation, fees and benefits. The FRB and the FDIC
published interagency safety and soundness standards which became effective
August 1995. Institutions or holding companies failing to meet the prescribed
standards will be required to submit a plan to correct any deficiencies. FDICIA
provides for certain mandatory and discretionary sanctions for failing to submit
or implement such a plan, including asset growth limits, capital directives and
deposit interest rate ceilings.

Brokered Deposits. During 1992 the FDIC adopted regulations pursuant to FDICIA
which govern the receipt of brokered deposits. Under the new regulations,
brokered deposits include any deposit obtained from or through a deposit broker
(as defined), and include deposits, however obtained, of institutions that offer
rates "significantly higher" than those in the market area. An institution may
only accept brokered deposits if it is (i) "well capitalized" or (ii)
"adequately capitalized" and receives a waiver from the FDIC. "Adequately
capitalized" institutions that receive waivers to accept brokered deposits are,
however, subject to certain limits on the maximum rates which they may pay on
such deposits. "Undercapitalized" institutions may not accept brokered deposits,
nor may they offer deposit instruments yielding in excess of 75 basis points
over prevailing yields offered on comparable instruments in the relevant market
area. Also, FDICIA provides that the FDIC shall not, in most circumstances,
provide deposit insurance coverage on a "pass-through" basis for certain
employee benefit plans to institutions prohibited from accepting brokered
deposits. The definitions of "well capitalized," "adequately capitalized" and
"undercapitalized" for purposes of the brokered deposit regulations generally
conform with the definitions of those terms adopted by the FDIC for purposes of
implementing the prompt corrective action provisions of FDICIA. See "-- Federal
Deposit Insurance Corporation Improvement Act of 1991 - Prompt Corrective
Action."

Real Estate Lending Standards. Pursuant to authority contained in FDICIA, the
federal banking agencies have adopted final regulations which require depository
institutions to establish and maintain written internal real estate lending
policies. These policies must be consistent with safe and sound banking
practices and be appropriate for the size and nature of the


                                       45
<PAGE>   52
institution involved. Additionally, they must be established by each institution
only after it has considered the Interagency Guidelines for Real Estate Lending
Policies, which are made a part of the final regulations. The regulations
require that certain specific standards be addressed relating to loan portfolio
diversification standards, prudent underwriting standards (including
loan-to-value limits), loan administration procedures, and documentation,
approval and reporting requirements. Each institution's lending policies must be
reviewed and approved by the institution's board of directors at least once a
year. Finally, each institution is expected to monitor conditions in its real
estate market to ensure that its lending policies are appropriate for current
market conditions. The regulations do not set forth specific loan-to-value
limits, but the Interagency Guidelines do provide certain limits which should
not be exceeded except under limited circumstances.

Deposit Insurance Assessments. On January 1, 1993, the FDIC began implementing a
risk-related premium schedule for all insured depository institutions which
resulted in the assessment of deposit insurance premiums based on certain
capital and supervisory measures, with the strongest institutions paying the
lowest premiums and the weakest institutions paying the highest premiums. The
risk-related premium schedule is established quarterly by the FDIC.

      Under the risk-related premium schedule, the FDIC, on a semiannual basis,
assigns each institution to one of three capital groups, "well capitalized,"
"adequately capitalized" or "undercapitalized," in each case generally
conforming to the definitions of these terms adopted by the FDIC for purposes of
implementing the prompt corrective action provisions of FDICIA. See "-- Federal
Deposit Insurance Corporation Improvement Act of 1991 - Prompt Corrective
Action." The FDIC further assigns each institution to one of three subgroups
within a capital group corresponding to the judgment of the FDIC and state
supervisor of its strength based on supervisory evaluation, including
examination reports, statistical analysis and other information relevant to
gauging the risk posed by the institution.

      Section 104 of the FDICIA provided for certain assessment rates for
recapitalizing the Bank Insurance Fund ("BIF Fund") by establishing target
reserve ratios for the BIF Fund to achieve reserves totaling $1.25 for every
$100 of insured deposits within a 15-year period. During 1995 the BIF Fund
reached $1.25 in reserves for every $100, and accordingly, the deposit insurance
assessment rates were reduced. Institutions deemed to have the highest risk pay
up to $0.27 for every $100 of deposits annually while those deemed to have the
least risk pay no insurance premium. Under the risk-related premium schedule,
the Bank's annual assessment rate during 1996 was zero and the Bank paid only
the minimum semi-annual premium of $1,000.

      On September 30, 1996 the Deposit Insurance Funds Act was enacted. This
Act provides for a new Financing Corporation (FICO) assessment for BIF members
not tied to the FDIC risk classification. The FICO BIF annual rate is $0.01296
per $100 in BIF-insured deposits, effective January 1, 1997.

Restrictions on Transfers of Funds to the Company by the Bank. The Company is a
legal entity separate and distinct from the Bank. At present, substantially all
of the Company's revenues, and cash flow including funds available for the
payments of dividends and other operating expenses, are paid by dividends to the
Company from the Bank.

      There are statutory and regulatory limitations on the amount of dividends
which may be paid to the Company by the Bank. California law restricts the
amount available for cash dividends by state-chartered banks to the lesser of
retained earnings or a bank's net income for its last three fiscal years (less
any distributions to shareholders made during such period). In the event a bank
has no retained earnings or net income for its last three fiscal years, cash
dividends may be paid in an amount not exceeding the net income for such bank's
last preceding fiscal year only after obtaining the prior approval of the
Superintendent. At December 31, 1996, the Bank had $9,020,000 legally available
for the payment of cash dividends.

      The Bank is subject to certain restrictions imposed by federal law on any
extensions of credit to, or the issuance of a guarantee or letter of credit on
behalf of, the Company or other affiliates, the purchase of or investment in
stock or other securities thereof, the taking of such securities as collateral
for loans and the purchase of assets of the Company or other affiliates. Such
restrictions prevent the Company and such other affiliates from borrowing from
the Bank unless the loans are secured by marketable obligations of designated
amounts. Further, such secured loans and investments by the Bank to the Company
or to any other affiliate are limited to 10% of the Bank's capital and surplus
(as defined


                                       46
<PAGE>   53
by federal regulations) and such secured loans and investments are limited, in
the aggregate, to 20% of the Bank's capital and surplus (as defined by federal
regulations). California law also imposes certain restrictions with respect to
transactions involving the Company and other controlling persons of the Bank.

Compliance with Environmental Regulation

      Management of the Company and the Bank is unaware of any material effect
upon the Company's and the Bank's capital expenditures, earnings or competitive
position as a result of compliance with federal, state and local provisions
which have been enacted or adopted regulating the discharge of material into the
local environment or otherwise relating to the protection of the environment.
Based on current federal, state and local environmental laws and regulations,
the Company does not intend to make any material capital expenditures for
environmental control facilities for either the remainder of its current fiscal
year or its succeeding fiscal year.

EFFECTS OF GOVERNMENTAL MONETARY POLICIES AND RECENT LEGISLATION

    Government Fiscal and Monetary Policies

      Banking is a business that depends on rate differentials. In general, the
difference between the interest rate paid by the Bank on its deposits and its
other borrowings and the interest rate received by the Bank on loans extended to
its customers and securities held in the Bank's portfolio comprise a major
portion of the Company's earnings. These rates are highly sensitive to many
factors that are beyond the control of the Bank. 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
FRB. The FRB implements national monetary policies (with objectives such as
curbing inflation and combating recession) by its open-market operations in
United States Government securities, by adjusting the required level of reserves
for financial institutions subject to its reserve requirements and by varying
the discount rates applicable to borrowings by depository institutions. The
actions of the FRB in these areas influence the growth of bank loans,
investments and deposits and also affect interest rates charged on loans and
paid on deposits. The nature and impact of any future changes in monetary
policies cannot be predicted.

      From time to time, legislation is enacted which has the effect of
increasing the cost of doing business, limiting or expanding permissible
activities or affecting the competitive balance between banks and other
financial institutions. Proposals to change the laws and regulations governing
the operations and taxation of banks, bank holding companies and other financial
institutions are frequently made in the U.S. Congress, in the California
legislature and before various bank regulatory and other professional agencies.
The likelihood of any major changes and the impact such changes might have on
the Company are impossible to predict. Certain of the potentially significant
changes which have been enacted, and proposals which have been made recently,
are discussed below.

    Interstate Banking

      With regard to any interstate banking, the Justice Department issued
merger guidelines in April 1992. On the basis of the revised criteria, the
Department has challenged several proposed transactions involving institutions
that compete directly in the same market(s). In contrast to the Justice
Department, the Federal Reserve has recently shown a greater inclination to
consider factors that contribute to the safety and soundness of the banking
system, or which contribute positively to the "convenience and needs" of the
affected communities. To the extent these two federal agencies apply different
(and at times incompatible) analysis to assess the competitive effects of
proposed bank in thrift mergers and acquisitions, federal anti-trust objections
must be considered in connection with any interstate acquisition.

      Banks contemplating acquisitions must comply with the competitive
standards of either the BHC Act, the Change in Bank Control Act ("CBA") or the
Bank Merger Act ("BMA"). The crucial test under each Act is whether the proposed
acquisition will "result in a monopoly" or will "substantially" lessen
competition in the relevant geographic market. Both


                                       47
<PAGE>   54
the BHC Act and the BMA preclude granting regulatory approval for any
transaction that will result in a monopoly or where the furtherance of a plan to
create a monopoly. However, where a proposed transaction is likely to cause a
substantial reduction in competition, or tends to create a monopoly or otherwise
restrain trade, both Acts permit the granting of regulatory approval if the
applicable regulator finds that the perceived anti-competitive effects of the
proposed transaction "are clearly outweighed in the public interest by the
probable effect of the transaction on the convenience and needs of the community
to be served."

      The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994
(the "Riegle-Neal Act") was signed into law on September 29, 1994. When fully
effective, the Riegle-Neal Act will significantly relax or eliminate many of the
current restrictions on interstate banking. Effective September 29, 1995, the
Riegle-Neal Act permits a bank holding company to acquire banks in states other
than its "home state," even if applicable state law would not permit that
acquisition. Such acquisitions would continue to require Board approval and
would remain subject to certain state laws.

      Effective June 1, 1997, the Riegle-Neal Act will permit interstate mergers
of banks, thereby allowing a single, merged bank to operate branches in multiple
states. The Riegle-Neal Act allows each state to adopt legislation to "opt-out"
of these interstate merger provisions. Conversely, the Riegle-Neal Act permits a
state to "opt in" to the merger provisions of Act prior to their stated
effective date in order to permit interstate mergers in that state prior to June
1, 1997.

      The Riegle-Neal Act may have the effect of increasing competition by
facilitating entry into the California banking market by out of state banks and
bank holding companies.

      On December 24, 1996 the Company entered into the Agreement and Plan of
Merger with Commerce Security Bancorp, Inc. providing for the acquisition of 100
percent of the outstanding shares of the Company in exchange for the right to
receive $23.00 cash for each share tendered.

CURRENT ACCOUNTING PRONOUNCEMENTS

      In June 1996, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 125 (SFAS 125), "Accounting for Transfer and
Servicing of Financial Assets and Extinguishment of Liabilities". SFAS 125
addresses the accounting for all types of securitization transactions,
securities lending and repurchase agreements, collateralized borrowing
arrangements and other transactions involving the transfer of financial assets.
SFAS 125 distinguishes transfers of financial assets that are sales from
transfers that are secured borrowings. SFAS 125 is generally effective for
transactions that occur after December 31, 1996, and it is to be applied
prospectively. SFAS 125 will require the allocation of the total cost of
mortgage loans sold to the mortgage loans sold (servicing released),
interest-only and retained certificates and servicing rights based on their
relative fair values. Under SFAS 125 the interest-only and retained certificates
and servicing rights are assessed for impairment based upon the fair value of
those rights. The pronouncement also requires the additional disclosure about
the interest-only and retained certificates in securitizations and the
accounting for these assets at fair value in accordance with Statement of
Financial Accounting Standards No. 115. Management believes the adoption of SFAS
125 on January 1, 1997 will not have a material impact on the Company's
operations.

EMPLOYEES

      At December 31, 1996 the Bank had approximately 96 full-time and 74
part-time employees, none of whom was represented by a union or collective
bargaining group or agent. Management believes that its relations with its
employees are satisfactory.

                           INFORMATION REGARDING CSBI

      CSBI is a Delaware business corporation registered as a bank holding
company under the BHC Act. Its principal place of business is 7777 Center
Avenue, Huntington Beach, California 92647-3067. CSBI operates its business
through three bank subsidiaries: Liberty National Bank ("Liberty"),
headquartered in Huntington Beach, California; San Dieguito National Bank ("San
Dieguito"), headquartered in Encinitas, California; and Commerce Security Bank
("Commerce"), headquartered in Sacramento, California.

      Each of Liberty, San Dieguito and Commerce is a commercial bank, with a
focus on the small business segment of the market. Each offers a full range of
commercial banking services, including the making of commercial loans to
businesses, installment loans to individuals, cash management services, business
and personal checking accounts, and savings and time deposits. Liberty, in
particular, is also an active originator and servicer of Small Business
Administration-guaranteed loans. In addition to its traditional commercial
banking operations, Commerce also operates both a residential mortgage division
and an equipment leasing division. While not a condition of the Merger, CSBI has
advised Eldorado that CSBI intends to consolidate, at minimum, Eldorado Bank,
Liberty and San Dieguito into a single entity contemporaneously with or as soon
as practicable after the Closing, subject to the approval of the applicable
regulatory authorities.

      CSBI is controlled by Dartmouth Capital Group, L.P. (the "Dartmouth
Partnership") and its general partner Dartmouth Capital Group, Inc., each of
which is registered as a bank holding company under the BHC Act. Robert P.
Keller, the President and Chief Executive Officer of CSBI, also serves as the
President of Dartmouth Capital Group, Inc., and a majority of CSBI's directors
also constitute a majority of the directors of Dartmouth Capital Group, Inc. The
Dartmouth Partnership acquired its current ownership interest in CSBI as the
result of the following transactions; its September 1995 investment in CSBI's
wholly-owned subsidiary, SDN Bancorp, Inc. ("SDN"), which permitted SDN to
recapitalize San Dieguito and to undertake a significant change in its strategic
direction; its March 1996 investment in SDN that provided the funding for SDN's
acquisition of Liberty; and its August 1996 investment that provided
substantially all of the funding for CSBI's acquisition of Commerce. The
Dartmouth Partnership and certain of its affiliates have agreed to provide a
significant portion of the funding for the Merger.

INDEPENDENT AUDITORS' REPORT

The Board of Directors and Shareholders of Eldorado Bancorp:

We have audited the consolidated balance sheets of Eldorado Bancorp and
subsidiary (the "Company") as of December 31, 1996 and 1995, and the related
consolidated statements of income, shareholders' equity and cash flows for each
of the years in the three-year period ended December 31, 1996. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Eldorado Bancorp and
subsidiary at December 31, 1996 and 1995, and the results of their operations
and their cash flows for each of the years in the three-year period ended
December 31, 1996 in conformity with generally accepted accounting principles.

As discussed in note 1 to the consolidated financial statements, the Company
adopted the provisions of the Financial Accounting Standards Board's Statements
of Financial Accounting Standards No. 115, Accounting for Certain Investments in
Debt and Equity Securities in 1994, No. 114, Accounting by Creditors for
Impairment of a Loan, as amended by No. 118, Accounting by Creditors for
Impairment of a Loan Income Recognition and Disclosures in 1995.

ELDORADO BANCORP AND SUBSIDIARY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

       The consolidated financial statements include the accounts of Eldorado
Bancorp ("Eldorado" or the "Company") and its wholly owned subsidiary, Eldorado
Bank ("Eldorado Bank" or the "Bank"). All intercompany balances and transactions
have been eliminated in consolidation. Eldorado Bancorp has no significant
assets or liabilities other than its investment in the Bank.

       The consolidated financial statements have been prepared in conformity
with generally accepted accounting principles and prevailing practices within
the banking industry. In preparing the consolidated financial statements,
management is required to make estimates and assumptions that affect the
reported amounts of assets and liabilities as of the date of the balance sheet
and revenues and expenses for the year. Actual results could differ
significantly from those estimates.

BUSINESS

The Company has no subsidiary or affiliated business other than the Bank. The
Company has not entered into any of the permitted non-banking activities. On
December 24, 1996 the Company entered into an Agreement and Plan of Merger with
Commerce Security Bancorp, Inc. providing for the acquisition of 100 percent of
the outstanding shares of the Company in exchange for the right to receive
$23.00 cash for each share tendered.

       The Bank provides a full range of banking services to individual and
corporate customers throughout Orange, Los Angeles, Riverside and San Bernardino
Counties. The Bank is subject to competition from other financial institutions.
The Bank is also subject to the regulations of certain federal and state
agencies and undergoes periodic examination by those regulatory authorities.

SECURITIES

      In May 1993, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 115, "Accounting for Certain Investments of
Debt and Equity Securities" ("SFAS 115"). SFAS 115 was required to be adopted by
the Company in 1994. Accordingly, the Company reclassified its entire investment
security portfolio as of January 1, 1994 as securities available-for-sale which
were adjusted to reflect fair value. Previously, the investment securities were
carried at cost, adjusted for the accretion of discounts and amortization of
premiums.

      SFAS 115 requires that investments be classified as "held-to-maturity",
"available-for-sale" or "trading securities". The statement defines investments
in securities as "held-to-maturity" based upon a positive intent and ability to
hold those securities to maturity. Investments held-to-maturity are reported at
amortized cost. Debt and equity securities that are bought and held principally
for the purpose of selling them in the near term are classified as "trading
securities" and are to be reported at fair value, with unrealized gains and
losses included in operations. Equity and debt securities not classified as
"held-to-maturity" or "trading securities" are classified as
"available-for-sale" and are recorded at fair value, with unrealized gains and
losses excluded from operations and reported as a separate component of
shareholders' equity, net of the tax effect. The designation of securities is
made by management at the time of acquisition.

LOANS AND DIRECT LEASE FINANCING

Loans are reported at the principal amount outstanding, net of unearned income.
Interest on loans is computed by methods which generally result in level rates
of return on principal amounts outstanding. Interest accruals are discontinued
when, in the opinion of management, it is deemed uncollectable.

                                      F-8
<PAGE>   70
       Loans on which the accrual of interest has been discontinued are
designated as nonaccrual loans. The accrual of interest on loans is discontinued
when reasonable doubt exists as to the full, timely collection of interest or
principal and, generally, when a loan becomes contractually past-due by 90 days
or more with respect to principal or interest. The accrual of interest may be
continued on a loan contractually past-due 90 days or more with respect to
interest or principal if the Company is in the process of collection, and
collection of principal and interest is deemed probable.

       When a loan is placed on nonaccrual status, all interest previously
accrued but not collected is reversed against current period income. Income on
such loans is then recognized only to the extent that cash is received and where
the future collection of principal is probable. Accruals are resumed on loans
only when they are brought fully current with respect to interest and principal
and when, in the judgment of management, the loan is estimated to be fully
collectible.

       A loan is classified as a restructured loan when certain modifications,
such as the reduction of interest rates to below market or forgiveness or
deferral of principal payments, are made to contractual terms due to a
borrower's financial condition. Certain restructured loan agreements call for
additional interest or principal to be paid on a deferred or contingent basis.

       The Bank has direct financing leases under which it purchases automobiles
and equipment which are in turn leased to its customers. Direct financing leases
are recorded at the sum of the aggregate lease rentals receivable and the
estimated residual value of the equipment, net of unearned income. The related
unearned income is deferred and amortized into income so as to produce a level
rate of return.

LOAN ORIGINATION FEES AND COSTS

Loan origination fees and direct costs associated with lending are netted and
amortized to interest income as an adjustment to the yield over the respective
lives of the loans using a method that approximates the level-yield method over
the period to maturity. At December 31, 1996 and 1995, net deferred loan fees
(costs) of $(132,000) and $222,000, respectively, are included in loans.

SALES OF LOANS

       The Bank has realized gains from the sale of the guaranteed portion of
"Small Business Administration" loans. Gains or losses are recognized upon
completion of the sale (net of related commissions paid that are directly
attributable to the sale) and are based on the difference between the net sales
proceeds and the relative fair value of the portion of the loan sold versus the
portion of the loan retained. Loans held for sale are carried at the lower of
cost or estimated market value.

ALLOWANCE FOR POSSIBLE CREDIT LOSSES

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

       Effective January 1, 1995, the Company adopted the Financial Accounting
Standard's Board Statement of Financial Accounting Standards No. 114 (SFAS 114),
"Accounting by Creditors for Impairment of a Loan," as amended by SFAS 118,
"Accounting by Creditors for Impairment of a Loan - Income Recognition and
Disclosures." SFAS 114 requires loans to be measured for impairment when it is
probable that all amounts, including principal and interest, will not be
collected in accordance with the contractual terms of the loan agreement. The
amount of impairment and any subsequent changes are recorded through the
provision for possible credit losses as an adjustment to the allowance for
possible credit losses. SFAS 114 applies to all loans, whether collateralized or
uncollateralized, except for large groups of smaller-balance homogenous loans
that are collectively evaluated for impairment, loans that are measured at fair
value or at the lower of


                                      F-9
<PAGE>   71
cost or fair value, leases, and debt securities. In addition, it usually applies
to loans that are restructured in a troubled debt restructuring involving a
modification of terms. However, such loans restructured prior to the effective
date of SFAS 114 that are performing in accordance with their restructured terms
are not considered impaired under SFAS 114.

       As required by SFAS 114, the Company generally measures impairment based
upon the present value of the loan's expected future cash flows, except where
foreclosure or liquidation is probable or when the primary source of repayment
is provided by real estate collateral. In these circumstances, impairment is
measured based upon the fair value of the collateral. In addition, in certain
rare circumstances, impairment may be based on the loan's observable fair value.

       Generally, the Company evaluates a loan for impairment in accordance with
SFAS 114 when it is placed on nonaccrual status. Adopting SFAS 114 did not
affect the Company's charge-off policy.

       The adoption of SFAS 114 did not have a material effect on the Company's
financial position or results of operations.

       Management believes that the allowance for possible credit losses is
adequate. While management uses available information to recognize losses on
loans and leases, future additions to the allowance may be necessary based on
changes in economic conditions. In addition, both federal and state regulators,
as an integral part of their examination process, periodically review the
Company's allowance for possible credit losses. These agencies may require the
Company to recognize additions to the allowance based on their judgment about
information available to them at the time of their examination.

OTHER REAL ESTATE OWNED

       Other real estate owned consists of real estate acquired in settlement of
loans. Other real estate owned is carried at the lower of cost or estimated fair
value less selling costs. The recognition of gains and losses on the sale of
real estate is dependent upon various factors relating to the nature of the
property sold, the terms of the sale and the future involvement of the Company.

       Real estate acquired in settlement of loans are recorded at the lower of
the unpaid balance of the loan at the settlement date or fair value less selling
costs of the collateral. Subsequently, valuation allowances for estimated losses
are provided against income if the carrying value of real estate exceeds
estimated fair value less selling costs. Legal fees and direct costs, including
foreclosure, appraisal and other related costs, are expensed as incurred. While
management uses available information to provide for losses on real estate,
future additions to the allowance may be necessary based on future economic
conditions. In addition, the regulatory agencies periodically review the
allowance for real estate losses and such agencies may require the Company to
recognize additions to the allowance based on information and factors not
available to management.

PREMISES AND EQUIPMENT

       Premises and equipment are stated at cost, less accumulated depreciation
and amortization which is charged to expense on a straight-line basis over the
estimated useful lives of the assets, from 3 to 30 years, or, in the case of
leasehold improvements, over the terms of the leases if shorter than the
estimated useful lives.

INTANGIBLE ASSETS

       The Company has classified as goodwill the cost in excess of fair value
of the net assets (including tax attributes) of businesses acquired in purchase
transactions. Goodwill is being amortized on a straight-line method over fifteen
years. The Company periodically reviews goodwill to assess recoverability from
projected, undiscounted net cash flows of the related business unit, and
impairments would be recognized in operating results if a permanent diminution
in value were to occur.

                                      F-10
<PAGE>   72
         Core deposit intangibles represents the intangible value of depositor
relationships resulting from deposits assumed in acquisitions and is amortized
over their useful economic life, not to exceed ten years.

INCOME TAXES

         Income taxes are accounted for under the asset and liability method of
accounting. Under the asset and liability method, deferred income taxes are
recognized for the expected future tax consequences attributable to differences
between the financial statement carrying amounts of existing assets and
liabilities and their respective tax bases. Deferred tax assets and liabilities
are measured using enacted tax rates expected to apply to taxable income in the
years in which those temporary differences are expected to be recovered or
settled. The effect on deferred taxes of a change in tax rates is recognized in
income in the period that includes the enactment date.

STATEMENTS OF CASH FLOWS

         For purposes of reporting cash flows, cash and cash equivalents include
cash and due from banks and federal funds sold. Generally, federal funds are
purchased and sold for one-day periods.

EARNINGS PER SHARE

         Earnings per share of common stock are based upon the weighted average
number of common shares, which include common stock and dilutive common stock
equivalent shares ("CSE") outstanding during each period, after giving
retroactive effect to stock dividends, including the 10 percent stock dividend
declared in November 1995.

         The calculations of earnings per share of common stock are as follows
for the periods indicated:

RECLASSIFICATIONS

         Certain items in prior periods have been reclassified to conform to the
current presentation.

CURRENT ACCOUNTING PRONOUNCEMENTS

         Prior to January 1, 1996, the Company accounted for its stock option
plan in accordance with the provisions of Accounting Principles Board ("APB")
Opinion No. 25, "Accounting for Stock Issued to Employees," and related
interpretations. As such, compensation expense would be recorded on the date of
grant only if the current market price of the underlying stock exceeded the
exercise price. On January 1, 1996, the Company adopted Statement of Financial
Accounting Standards No. 123, "Accounting for Stock-Based Compensation" (SFAS
123), 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 APB Opinion No.
25 and provide pro forma net income


                                      F-11
<PAGE>   73

and pro forma earnings per share disclosures for employee stock option grants
made in 1995 and future years 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 No. 25 and provide the pro forma disclosure provisions
of SFAS 123. See Note (9) of the Notes to Consolidated Financial Statements for
the pro forma net income and pro forma earnings per share disclosures.

         In June 1996, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 125 (SFAS 125), "Accounting for Transfer
and Servicing of Financial Assets and Extinguishment of Liabilities." SFAS 125
addresses the accounting for all types of securitization transactions,
securities lending and repurchase agreements, collateralized borrowing
arrangements and other transactions involving the transfer of financial assets.
SFAS 125 distinguishes transfers of financial assets that are sales from
transfers that are secured borrowings. SFAS 125 is generally effective for
transactions that occur after December 31, 1996, and it is to be applied
prospectively. SFAS 125 will requires the allocation of the total cost of
mortgage loans sold to the mortgage loans sold (servicing released),
interest-only and retained certificates and servicing rights based on their
relative fair values. Under SFAS 125 the interest-only and retained certificates
and servicing rights are assessed for impairment based upon the fair value of
those rights. The pronouncement also requires the additional disclosure about
the interest-only and retained certificates in securitizations and the
accounting for these assets at fair value in accordance with Statement of
Financial Accounting Standards No. 115. Management believes the adoption of SFAS
125 on January 1, 1997 will not have a material impact on the Company's
operations.

(2)      ACQUISITION OF MARINERS BANK

         On October 20, 1995, the Company acquired 100% of the outstanding
common stock of Mariners Bancorp ("Mariners") for $4,072,000 in cash and the
issuance of 630,276 common shares of Eldorado Bancorp, valued at $14.625 per
share. Mariners had total assets of approximately $75,263,000. The acquisition
was accounted for using the purchase method of accounting in accordance with
Accounting Principles Board Opinion No. 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 Mariners from the date of the acquisition. Goodwill and core deposit
intangibles arising from the transaction totaled approximately $7,007,000.
Goodwill of $5,511,000 is being amortized over fifteen years on a straight-line
basis. A core deposit intangible of $1,496,000 is being amortized over its
useful economic life of ten years.

         The following table sets forth selected unaudited pro forma combined
financial information of the Company and Mariners for the years ended December
31, 1995 and 1994. The pro forma operating data reflects the effect of the
acquisition of Mariners as if it was consummated at the beginning of each year
presented. The pro forma results are not necessarily indicative of the results
that would have occurred had the acquisition been in effect for the full years
presented, nor are they necessarily indicative of the results of future
operations.

         The Bank serviced loans for others totaling $79,075,000 and $89,908,000
at December 31, 1996 and 1995, respectively.

         The Company grants construction, commercial and consumer loans to
customers throughout the Southern California area. Although the Company has a
diversified loan portfolio, a substantial portion of its debtors' ability to
honor their contracts is dependent upon the real estate markets in Orange, Los
Angeles, Riverside and San Bernardino counties of California.

         In the ordinary course of business, the Bank has granted loans to
certain related parties and their affiliates. These loans are made under terms
which are consistent with the Bank's normal lending policies. A summary of
activity with respect to these loans follows:

</TABLE>



         At December 31, 1996, 1995 and 1994, the Bank had loans of
approximately $,661,000, $5,818,000, and $3,161,000 respectively, on which the
accrual of interest had been discontinued. If these loans had been current
throughout their terms, interest and fees on loans would have increased by
approximately $343,000, $172,000, and $144,000 for 1996, 1995 and 1994,
respectively.

         Loans restructured, prior to January 1, 1995, the effective date of
SFAS 114, and performing within the terms of the restructured agreement amounted
to $3,425,000 and $1,531,000 at December 31, 1996 and 1995, respectively. Under
the original terms of the loans, interest earned would have totaled $496,000 and
$235,000 for the year ended December 31, 1996 and 1995, respectively. The
recorded interest income amounted to $316,000 and $187,000 for 1996 and 1995,
respectively.

         The following is a summary of impaired loans and the related allowance
for possible credit losses at December 31,:

</TABLE>

         The Company's policy for recognizing interest income on impaired loans
is the same as the policy applied to nonaccrual loans prior to the adoption of
SFAS 114. When the collectibility of principal on a loan is in doubt, all
payments received are applied as a reduction to principal. There was no interest
income recognized on impaired loans for the year ended December 31, 1996.

         The determination of the allowance for possible credit losses requires
the use of certain significant estimates by Management in relation to the
ultimate repayment of loans. These amounts could differ materially in the near
term from the amounts assumed in arriving at the allowance for possible loan
losses in December 31, 1996.

</TABLE>

         In determining the possible future realization of deferred tax assets,
the Company takes future taxable income from the following sources into account:
(a) the reversal of taxable temporary differences; (b) future operations
exclusive of reversing temporary differences; (c) tax planning strategies that,
if necessary, would be implemented to accelerate taxable income into years in
which net operating losses might otherwise expire. As of December 31, 1996 and
1995, there was no valuation allowance against deferred tax assets. Deferred tax
assets as of December 31, 1996 and 1995 have been recognized to the extent of
the expected reversal of taxable temporary differences and the amount of Federal
income tax paid in the carryback period which would be recoverable through the
carryback of net operating losses.

         Certain factors beyond management's control can effect future levels of
earnings and no assurance can be given that sufficient earnings will be
generated to fully realize the recorded tax benefits. Management believes,
however, that the remaining temporary differences will reverse during periods in
which the Company generates net taxable earnings.

(9) STOCK OPTION PLANS

         A stock option plan approved by the shareholders in 1989 ("1989 Plan")
provides that incentive stock options and nonqualified options covering an
aggregate of 145,200 shares (after giving retroactive effect for stock
dividends) of the Company's unissued common stock may be granted to salaried
officers, key employees or directors at prices no less than the fair market
value of such shares at dates of grant. Options granted may be exercised at a
rate of 20% per year and expire five years from the date the options are
granted. A stock option plan approved by the shareholders in 1992 ("1992 Plan")
provides that incentive stock options and nonqualified options covering an
aggregate of 154,000 shares (after giving retroactive effect for stock
dividends) of the Company's unissued common stock may be granted to salaried
officers, key employees or directors at prices no less than the fair market
value of such shares at dates of grant. Options granted may be exercised at a
rate of 20% per year and expire five years from the date the options are
granted.

         A stock option plan approved by the shareholders in 1995 ("1995 Plan")
provides that options covering an aggregate of 143,000 shares (after giving
retroactive effect for stock dividends) of the Company's unissued common stock
may be granted to salaried officers, key employees or directors at prices no
less than the fair market value of such shares at


                                      F-18

dates of grant. Options granted may be exercised at a rate of 20% per year and
expire five years from the date the options are granted.

                                          ==============      ==============      ==============
</TABLE>


         At December 31, 1996 138,957 options were exercisable at prices ranging
from $7.39 to $15.125 per share and there were 61,037 shares available for grant
under the Plans. The per share weighted-average fair value of stock options
granted during 1996 and 1995 was $2.72 and $2.46 on the date of grant using the
Black Scholes option-pricing model with the following weighted-average
assumptions: 1996 - expected dividend yield 3.0%, risk-free interest rate of
5.53%, an expected life of 4 years and expected volatility of 20 percent; 1995
- -expected dividend yield 3.4%, risk-free interest rate of 6.27%, an expected
life of 4 years and expected volatility of 20 percent. The Company applies APB
Opinion No. 25 in accounting for its Plan and, accordingly, no compensation cost
has been recognized for its stock options in the financial statements. Had the
Company determined compensation cost based on the fair value at the grant date
for its stock options under SFAS 123, the Company's net earnings would have been
reduced to the pro forma amounts indicated below:

</TABLE>


         Pro forma net earnings reflects only options granted in 1996 and 1995.
Therefore, the full impact of calculating compensation cost for stock options
under SFAS 123 is not reflected in the pro forma net earnings amounts presented
above because compensation cost is reflected over the options' vesting period of
5 years and compensation cost for options granted prior to January 1, 1995 is
not considered.

(10) EMPLOYEE BENEFIT PLANS

         The Company has a stock bonus plan covering substantially all employees
who satisfy the age and length of service requirements. Under the terms of the
plan, the Company contributes to a trust fund such amounts (not to exceed 15% of
compensation) as determined annually by the Board of Directors. The Company's
contribution was approximately $120,000, $200,000, and $60,000 for 1996, 1995
and 1994, respectively.

         The Company has a pretax savings and profit sharing plan under Section
401(k) of the Internal Revenue Code. The employees of the Company are eligible
to participate in the 401(k) profit sharing plan if they are twenty-one years of
age or older and have completed 500 hours of service. Under the plan, eligible
employees are able to contribute up to 10% of their compensation (some
limitations apply to highly compensated employees). Company contributions are
discretionary and are determined annually by the Board of Directors. The
Company's contribution was approximately $95,000, $60,000, and $24,000 for 1996,
1995 and 1994, respectively.

         The Company has an employment agreement with certain executive officers
covering an approximate three year period. This agreement contains an incentive
compensation provision which provides for payment, in addition to regular
salary, of an amount based upon Company earnings (adjusted for certain
transactions) in excess of a stated return on equity. The agreement also
provides for a defined benefit pension plan that includes the following pension
costs for the years ended December 31, 1996 and 1995:

(12) COMMITMENTS AND CONTINGENCIES

         The Company leases facilities from nonaffiliated parties under
operating leases expiring at various dates through April 2011. A majority of the
leases contain renewal options covering periods ranging from one to thirty
years. Certain leases for bank premises provide for the payment by the lessee of
property taxes, insurance premiums, cost of maintenance and other items. Total
rental expense before sublease rental income amounted to approximately
$1,092,000, $918,000 and $957,000 in 1996, 1995, and 1994, respectively.

         In connection with the 1986 sale of its North San Bernardino branch,
the Company subleased the facilities to the nonaffiliated purchaser under a
lease which expires in February 2006, with one renewal option for five years.
Rental income for 1996, 1995 and 1994 under this lease was approximately
$108,000 each year.

         Future minimum rental payments and rental income receivable under
noncancellable operating leases are as follows:

</TABLE>

         In the normal course of business, the Bank makes various commitments
and incurs certain contingent liabilities which are not reflected in the
accompanying consolidated financial statements. These commitments and
contingencies include various guarantees, commitments to extend credit and
standby and commercial letters of credit. At December 31, 1996 and 1995, the
Bank had outstanding commitments to extend credit of approximately $83,987,000
and $77,209,000, respectively, of which $953,000 and $1,808,000, respectively,
related to commercial letters of credit.

         Commitments to extend credit are agreements to lend to a customer as
long as there is no violation of any condition established in the contract.
Standby letters of credit and financial guarantees written are conditional
commitments issued by the Bank to guarantee the performance of a customer to a
third party. Commitments generally have fixed expiration dates or other
termination clauses and may require payment of a fee. Since many of the
commitments are expected to expire without being drawn upon, the total
commitment amounts do not necessarily represent future cash requirements. The
credit risk involved in issuing letters of credit is essentially the same as
that involved in extending loan


                                      F-21
<PAGE>   83

facilities to customers. The Bank evaluates each customer's credit-worthiness on
a case-by-case basis. The amount of collateral obtained, if deemed necessary by
the Bank upon extension of credit, is based on management's credit evaluation of
the counter-party. Collateral held varies but may include accounts receivable,
inventory, property, plant and equipment, and income-producing commercial
properties.

REGULATORY MATTERS

         The Federal Deposit Insurance Corporation Improvement Act of 1991
("FDICIA") was signed into law on December 19, 1991. Regulations implementing
the prompt corrective action provisions of FDICIA became effective on December
19, 1992. In addition to the prompt corrective action requirements, FDICIA
includes significant changes to the legal and regulatory environment for insured
depository institutions, including reductions in insurance coverage for certain
kinds of deposits, increased supervision by the Federal regulatory agencies,
increased reporting requirements for insured institutions and new regulations
concerning internal controls, accounting and operations.

         The prompt corrective action regulations define specific capital
categories based on an institution's capital ratios. The capital categories, in
declining order, are "well capitalized," "adequately capitalized,"
"undercapitalized," "significantly undercapitalized" and "critically
undercapitalized." Institutions categorized as "undercapitalized" or worse are
subject to certain restrictions, including the requirement to file a capital
plan with its primary Federal regulator, prohibitions on the payment of
dividends and management fees, restrictions on executive compensation and
increased supervisory monitoring, among other things. Other restrictions may be
imposed on the institution by the FDIC, including requirements to raise
additional capital, sell assets or sell the entire institution.

         To be considered "adequately capitalized," an institution must
generally have a leverage ratio of at least 4%, a Tier 1 risk-based capital
ratio of at least 4% and a total risk-based capital ratio of at least 8%. An
institution is deemed to be "critically undercapitalized" if it has a tangible
equity ratio of 2% or less.

         At December 31, 1996, the Bank's leverage ratio was 9.53%, Tier 1
risk-based ratio was 14.30% and total risk-based ratio was 15.56% . At December
31, 1996 the Bank is in the "well-capitalized" category.

         The Bank's actual capital amounts and ratios, in addition to amounts
required to be categorized as adequately-capitalized and well-capitalized are
shown in the following table:

LITIGATION

         The Company is party to various lawsuits which have arisen in the
normal course of its business. In the opinion of management, based upon the
advice of the Company's legal counsel, the disposition of all pending litigation
will not have a material adverse effect on the Company's consolidated financial
statements.

(13) FEDERAL RESERVE ACT

         Section 23A of the Federal Reserve Act restricts the Bank from making
loans or advances to the Company in excess of 10% of its capital stock and
surplus. Each loan or extension of credit to the Company must be secured at the
time of transaction by collateral having a market value of 100% or 130%,
depending on the collateral, of the amount funded. At December 31, 1996, the
Bank is permitted to make loans of approximately $3,245,000 to the Company.

(14) DISCLOSURE ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

         Statement of Financial Accounting Standards No. 107, "Disclosures about
Fair Value of Financial Instruments," requires that the Company disclose
estimated fair values for its financial instruments. Fair value estimates,
methods, and assumptions are set forth below for the Bank's financial
instruments.

         The following methods and assumptions were used to estimate the fair
value of each class of financial instruments for which it is practicable to
estimate the value:

CASH AND SHORT-TERM INVESTMENTS

         For cash and short-term investments, the carrying amount is a
reasonable estimate of fair value.

SECURITIES

         The fair value of the securities is estimated based on bid prices
published in financial sources or bid quotations received from securities
dealers.

LOAN RECEIVABLES

         Fair values are estimated for portfolios of loans with similar
financial characteristics. The fair value of loans is calculated by discounting
estimated future cash flows using current rates that similar loans would be made
to borrowers with similar credit ratings and for the same remaining maturities.

DEPOSIT LIABILITIES

         The fair value of demand deposits, savings accounts, and money market
deposits is the amount payable on demand at the reporting date. The fair value
of certificates of deposit is based on the discounted value of contractual cash
flows using market rates.


                                      F-23
<PAGE>   85

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 creditworthiness of the counterparties.
For fixed-rate loan commitments, fair value also considers the difference
between current levels of interest rates and the committed rates. The fair value
of guarantees and 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.

</TABLE>


LIMITATIONS

         Fair value estimates are made at a specific point in time, based on
relevant market information and information about the financial instrument.
These estimates do not reflect a premium or discount that could result from
offering for sale at one time the Company's entire holdings of a particular
financial instrument. Because no markets exists for a significant portion of the
Company's financial instruments, fair value estimates are based on judgments
regarding future expected loss experience, current economic conditions, risk
characteristics of various financial instruments, and other factors. These
estimates are subjective in nature and involve uncertainties and matters of
significant judgment and therefore cannot be determined with precision. Changes
in assumptions could significantly affect the estimates.

         Fair value estimates are based on existing on-and off-balance sheet
financial instruments without attempting to estimate the value of anticipated
future business and the value of assets and liabilities that are not considered
financial instruments. Other significant assets and liabilities that are not
considered financial assets or liabilities include property, plant, equipment,
and goodwill. In addition, the tax ramifications related to the realization of
the unrealized gains and losses can have a significant effect on fair value
estimates and have not been considered in the estimates.

(17) AGREEMENT AND PLAN OF MERGER

         On December 24, 1996, the Company entered into an Agreement and Plan of
Merger ("Merger Agreement") with Commerce Security Bancorp, Inc. ("CSBI") that
provides for CSBI to acquire 100 percent of the outstanding shares of the
Company by means of a cash merger in which each Company share will be converted
into the right to receive cash in the amount of $23.00. The proposed merger
requires certain regulatory approvals and the approval of the principal terms of
the Merger Agreement by the holders of a majority of the outstanding shares of
common stock of the Company, in addition to the satisfaction of other
conditions.

         One condition to the Merger Agreement was that the Company enter into a
stock option agreement with CSBI dated December 24, 1996 ("Stock Option
Agreement"). The Company has granted to CSBI an option to purchase up to 468,200
shares of Company common stock (representing approximately 11 percent of the
issued and outstanding shares of Company common stock after taking into account
the shares of common stock issuable upon exercise of the option) at an exercise
price of $22.00 per share. The option is exercisable only if CSBI becomes
entitled to certain rights provided by the Merger Agreement related to the
termination of the Merger Agreement. Once the option becomes exercisable, it
will terminate upon the earliest to occur of: (i) the exercise of the option in
full or (ii) twelve (12) months following the termination of the Merger
Agreement, or such earlier date as the holder of the option realizes net profits
from the option of $1,000,000.

                                   THE MERGER

         2.1 THE MERGER. Eldorado and Merger Sub shall be the constituent
corporations to the Merger. Subject to the terms and conditions of this
Agreement, at the Effective Time, the Merger shall be effected by means of a
merger (hereinafter sometimes referred to as the "Merger") of Merger Sub with
and into Eldorado in accordance with Section 1108 of the Corporations Code and
Section 252 of the Delaware General Corporation Law, to be effected in
California by the filing of an Agreement of Merger substantially in the form
attached hereto as Exhibit 2.1 and to be effected in Delaware by the filing of
an appropriate Certificate of Merger. In accordance with each such statute, at
the Effective Time, the corporate existence of Merger Sub shall be merged into
Eldorado, and Eldorado shall be the Surviving Corporation and shall continue its
corporate existence under the laws of the State of California.

         2.2 CORPORATE DOCUMENTS, DIRECTORS AND OFFICERS. From and after the
Effective Time and thereafter until amended as provided by law, the Articles of
Incorporation and By-laws of the Surviving Corporation shall be the Articles of
Incorporation and By-laws of Eldorado as in effect immediately prior to the
Effective Time. The directors and officers of the Surviving Corporation
initially shall be comprised of all of the directors and officers of Merger Sub
immediately prior to the Effective Time, and each such director or officer shall
serve until his or her successor has been duly elected or appointed and
qualified or until his or her earlier death, resignation or removal in
accordance with the terms of the Surviving Corporation's Articles of
Incorporation and By-laws.

         2.3 TREATMENT OF COMMON STOCK AND MERGER SUB STOCK.

                  2.3.1 Conversion of Common Stock. At the Effective Time, each
share of Common Stock issued and outstanding immediately prior to the Effective
Time, excluding Dissenting Shares and Excluded Shares, shall, by virtue of the
Merger and without any action on the part of the holder thereof, be

                                       A-7
<PAGE>   99
APPENDIX A


converted into the right to receive, in cash, the sum of $23.00 (the "Merger
Consideration"). All shares of Common Stock converted into the right to receive
the Merger Consideration pursuant to the preceding sentence shall, as of the
Effective Time, no longer be outstanding and shall automatically be cancelled
and shall cease to exist, and each certificate previously representing any such
shares shall thereafter represent only the right to receive the Merger
Consideration into which the shares of Common Stock represented by such
certificate have been converted. As of the Effective Time, all Excluded Shares
shall cease to exist and the certificates for such shares shall, as promptly as
practicable thereafter, be cancelled and no payments shall be made in
consideration therefor.

                  2.3.2 Dissenting Shares. Notwithstanding anything in this
Agreement to the contrary, Dissenting Shares shall not be converted into the
right to receive, or be exchangeable for, the Merger Consideration provided for
in Section 2.3.1 hereof, but, instead, the holders thereof shall be entitled to
payment for such Dissenting Shares in accordance with the provisions of Chapter
13 of the Corporations Code unless and until a holder of Dissenting Shares shall
have failed to perfect or shall have effectively withdrawn or lost such holder's
rights to appraisal and payment, as the case may be. Eldorado shall (a) give
CSBI prompt written notice of (x) the identities of all Shareholders who have
perfected rights to dissent pursuant to Corporations Code Chapter 13 and (y) the
receipt of any notice from a Shareholder demanding the purchase of his, her or
its shares, (b) not settle or offer to settle any such demands without the prior
written consent of CSBI, and (c) not, without the prior written consent of CSBI,
waive any vote in favor of the Merger or failure of a Shareholder timely to take
any other action required under Corporations Code Chapter 13.

                  2.3.3 Payment to Exchange Agent. Subject to the terms and
conditions hereof, and subject to reduction by (a) the amount of the Deposit and
(b) any amount funded by Eldorado in accordance with the immediately following
sentence, immediately prior to the Closing CSBI shall deliver or cause to be
delivered to the Exchange Agent, for the benefit of the Shareholders, such
amount of cash (in same day funds) as is sufficient to pay the aggregate Merger
Consideration that Shareholders are entitled to receive pursuant to Section
2.3.1. Subject to the terms and conditions hereof, immediately prior to the
Closing Eldorado shall pay to the Exchange Agent, for inclusion in the Merger
Consideration, such amount of cash (in same day funds) (the "Redemption"), if
any, as to which payment (x) CSBI has obtained all necessary approvals by Bank
Regulators and (y) CSBI's California counsel has reasonably determined, and has
so advised the Board of Directors, that such payment will not result in a
violation of Section ___ et seq. of the California Financial Code or any other
provision of law applicable to Eldorado or the Bank. The directors and officers
of Eldorado shall be entitled to rely on such determination by CSBI's counsel,
without separate investigation by such directors and/or officers, and CSBI shall
indemnify and hold harmless each director and officer of Eldorado against any
liability arising out of any payment of a Redemption by Eldorado to the full
extent provided under Section 5.11.2.

                  2.3.4 Conversion of Merger Sub Stock. At the Effective Time,
the shares of common stock of Merger Sub then issued and outstanding shall be
converted into a like number of shares of common stock of the Surviving
Corporation, which thereafter shall constitute all of the issued and outstanding
shares of common stock of the Surviving Corporation. From and after the
Effective Time, the authorized capital stock of the Surviving Corporation shall
consist of the authorized capital stock of Merger Sub.

         2.4 EXCHANGE OF CERTIFICATES.

                  2.4.1 Common Stock Exchange Procedures. After the Effective
Time, each holder of a 

                                       A-8
<PAGE>   100
APPENDIX A


certificate or certificates theretofore representing shares of issued and
outstanding Common Stock (other than the Dissenting Shares and Excluded Shares)
shall, upon the surrender of such certificates to the Exchange Agent, be
entitled to receive in exchange therefor the amount of cash into which Common
Stock theretofore represented by the certificate or certificates so surrendered
shall have been converted as provided in Section 2.3.1, without interest and
subject to any required withholding of Taxes. The holder of a certificate that
prior to the Merger represented issued and outstanding shares of Common Stock
shall have no rights, after the Effective Time, with respect to such shares
except to surrender the certificate in exchange for cash without interest
thereon or, if applicable, to perfect such rights as a holder of Dissenting
Shares as such holder may have pursuant to the applicable provisions of Chapter
13 of the Corporations Code. Within two (2) Business Days after the Effective
Time, the Surviving Corporation will send, or will cause the Exchange Agent to
send, to each holder of Common Stock at the Effective Time a letter of
transmittal for use in such exchange; provided, however, that, to the extent
permitted by law, CSBI agrees to make appropriate arrangements for the earlier
surrender of share certificates and payment in same-day funds immediately
following the Effective Time with respect to any Shareholder who will receive in
excess of $1,000,000 of Merger Consideration.

                  2.4.2 Certain Taxes. If any payment for shares of Common Stock
is to be made in a name other than that in which the certificate surrendered in
exchange therefor is registered, it shall be a condition of such payment that
the certificate so surrendered shall be properly endorsed (or accompanied by an
appropriate instrument of transfer) and otherwise in proper form for transfer,
and that the person requesting such exchange shall pay to the Exchange Agent, in
advance, any transfer or other Taxes required by reason of the payment to a
person other than the registered holder of the certificate surrendered, or
required for any other reason, or shall establish to the satisfaction of the
Exchange Agent that such Tax has been paid or is not payable.

                  2.4.3 Lost, Stolen or Destroyed Certificate. In the event any
certificate shall have been lost, stolen or destroyed, upon the making of an
affidavit of that fact by the Person claiming such certificate to be lost,
stolen or destroyed and, if required by the Surviving Corporation, the posting
by such person of a bond in such amount as the Surviving Corporation may direct
as indemnity against any claim that may be made against it with respect to such
certificate, the Exchange Agent will issue in exchange for such lost, stolen or
destroyed certificate the cash deliverable in respect thereof pursuant to
Section 2.4.1.

                  2.4.4 Unclaimed Monies. Any portion of the cash paid to the
Exchange Agent by or on behalf of CSBI (together with any investment income
earned thereon) that remains unclaimed by the Shareholders pursuant to the
provisions of Section 2.4.1 six months after the Closing Date shall be returned
to CSBI, upon demand, and any Shareholder who has not exchanged his, her or its
shares of Common Stock for the Merger Consideration in accordance with Section
2.4.1 prior to that time shall thereafter look solely to CSBI for payment in
respect of such shares. Notwithstanding the foregoing, neither CSBI, the
Surviving Corporation, the Bank, the Exchange Agent nor any other Person shall
be liable to any Shareholder for any amount paid to a public official pursuant
to applicable abandoned property laws.

APPENDIX A


         2.5 TREATMENT OF OPTIONS. Immediately prior to the Effective Time, each
holder of a then-outstanding Option shall be entitled (whether or not such
Option is then vested or exercisable) to receive, in cancellation of such
option, a cash payment (an "Option Cancellation Payment") in an amount equal to
the excess of the Merger Consideration over the per-share exercise price of such
Option, multiplied by the number of shares of Common Stock covered by such
Option, subject to any required withholding of Taxes. Nothing in this Section
2.5 shall be construed as preventing a holder from exercising his or her Option
prior to the Effective Time. Such Option Cancellation Payments shall be paid
contemporaneously with the Closing. Eldorado shall take appropriate steps to
obtain from each of the several Optionholders a cancellation agreement, in form
and substance acceptable to CSBI, cancelling each outstanding Option in
consideration of the applicable Option Cancellation Payment. Notwithstanding the
foregoing, CSBI may enter into agreements with one or more Optionholders, in the
sole discretion of CSBI and such Optionholder, providing for the cancellation of
some or all of such holder's Options for consideration consisting of options to
purchase CSBI common stock or for any other mutually agreeable consideration, in
each case in lieu of an Option Cancellation Payment, provided only that no such
agreement shall provide for a cash payment to the applicable Optionholder in
excess of the Option Cancellation Payment to which such Optionholder would
otherwise be entitled.

         2.6 CLOSING OF TRANSFER BOOKS. At the Effective Time, the transfer
books for Common Stock shall be closed, and no transfer of shares of Common
Stock shall thereafter be made on such books. If, after the Effective Time,
certificates representing such shares are presented for transfer to the Exchange
Agent, they shall be cancelled and exchanged for the Merger Consideration as
provided in this Article II.

         2.7 DEPOSIT BY CSBI. Concurrently herewith, (a) CSBI is delivering to
the Deposit Escrow Agent the sum of Four Million Five Hundred Thousand Dollars
($4,500,000) (together with all earnings thereon, the "Deposit"), and (b) CSBI,
Eldorado and the Deposit Escrow Agent are entering into the Deposit Escrow
Agreement. Upon the Closing, the Deposit shall be disbursed to the Exchange
Agent. The disposition of the Deposit upon any termination of this Agreement
shall be in accordance with Section 7.5.2. Each of CSBI and Eldorado shall
promptly take such steps as may be necessary to effect this Section, including,
without limitation, issuing such written instructions and taking such other
actions as the Deposit Escrow Agent may request. Except to the extent provided
to the contrary in subsection 7.6.3(c) or in the Deposit Escrow Agreement, the
disposition of the Deposit pursuant to this Section 2.7 shall not prejudice any
rights or remedies that the Parties may otherwise have pursuant to this
Agreement.

APPENDIX A


commitment or agreement. The aggregate exercise price of all Options outstanding
as of the date hereof is $3,226,801.10. Schedule 3.2.3 hereto sets forth, with
regard to each Option outstanding as of the date hereof, the name of the holder,
the number of shares of Common Stock the holder is entitled to purchase, the

outstanding contractual obligations of either Eldorado or the Bank to
repurchase, redeem or otherwise acquire any shares of capital stock of Eldorado.
There are no bonds, debentures, notes or other instruments evidencing

the consummation of the Merger is the affirmative vote of the holders of a
majority of the outstanding shares of Common Stock entitled to vote thereon
approving the Merger. No other corporate proceedings on the part of Eldorado not
heretofore taken are necessary to approve this Agreement or to consummate the
Merger. This Agreement has been duly executed and delivered by Eldorado and
(assuming due authorization, execution and delivery by CSBI) constitutes the
valid and binding obligation of Eldorado, enforceable in accordance with its
terms, subject only to Laws regarding bankruptcy, insolvency, reorganization
moratorium or otherwise affecting creditors' rights generally, and to the
application of general principles of equity (whether considered in a proceeding
at law or in equity).

         3.5 CONFLICTS. Except as described on Schedule 3.5, the execution and
delivery of this Agreement does not, and the consummation of the Merger will
not, result in any Violation of any provision of the Articles of Incorporation

approvals, orders, authorizations, registrations, declarations and filings

would have a Material Adverse Effect on Eldorado or materially interfere with
Eldorado's ability to consummate the Merger.

obligations of any nature, whether absolute, accrued, contingent or otherwise,
and whether due or to become due, which relate to transactions entered into, or
any state of facts existing, on or before the date hereof and which would be
required under GAAP to

be shown on an audited balance sheet as of the date hereof or referenced in
notes thereto if such balance sheet or notes existed.

         3.10 CRITICIZED ASSETS, RESERVES AND CERTAIN OTHER ASSETS. As of the
date specified on Part A of Schedule 3.10 (which date is not earlier than three
(3) Business Days prior to the date hereof), and excepting assets with respect
to which the aggregate Borrower Group Obligations are less than $100,000, the
only assets of Eldorado that were (a) Criticized Assets, or (b) over 90 days
delinquent in payment of principal or interest or, to Eldorado's Knowledge,
materially in default of any other material provision of the operative
documents, whether or not the same are Criticized Assets, are those listed on
Part A of Schedule 3.10 hereto (which schedule identifies the loan, the current
book balance, the amount of loan loss reserve, if any, specifically allocated
thereto, and the loan classification). The loan and other asset classification
procedures utilized by Eldorado are in accordance with RAP and prudent banking
practice, and are consistently applied. As of the Most Recent Balance Sheet
Date, Eldorado's specific allowance for loan losses with regard to Classified
Assets was $4,839,000. Part B or Schedule 3.10 hereto sets forth all loans of
Eldorado (whether or not they are Classified Assets or are otherwise in default)
to any director, executive officer or ten percent shareholder of Eldorado, or to
Eldorado's Knowledge, any corporation or enterprise controlling, controlled by
or under common control with any of the foregoing.

         3.11 INVESTMENT SECURITIES; DERIVATIVES. Part A of Schedule 3.11
describes all of the investment securities, mortgage backed securities and
securities held for sale of Eldorado as of the date hereof, including (to the
extent applicable to that type of security) descriptions of such securities,
CUSIP numbers, pool face values, coupon rates, book values and market values
(approximated by Eldorado management in the case of illiquid securities) and, in
each case as of November 30, 1996 (or as of the date of acquisition, if later
acquired). Except as disclosed on Part B of Schedule 3.11, since December 31,
1994, Eldorado has not engaged in any transaction in or involving forwards,
futures, options on futures, swaps or other derivative instruments except as
agent on the order and for the account of others. To Eldorado's Knowledge, none
of the counterparties to any contract or agreement with respect to any such
instrument is in default with respect to such contract or agreement and no such
contract or agreement, were it to be a loan held by Eldorado, would be a
Criticized Asset. The financial position of Eldorado under or with respect to
each instrument set forth on Part B of Schedule 3.11 has been reflected on the
books and records of Eldorado in accordance with GAAP, and no open exposure of
Eldorado with respect to any such instrument (or with respect to multiple
instruments with respect to any single counterparty) exceeds $100,000.

         3.12 ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as disclosed on
Schedule 3.12, since September 30, 1996, (a) no event or development has
occurred that, individually or in the aggregate, has had or could reasonably be
expected to have a Material Adverse Effect on Eldorado, and (b) Eldorado has
carried on its business in the ordinary and usual course consistent with its
past practices. Except (x) as disclosed on Schedule 3.12, (y) increases required
by applicable Law or by an employment contract disclosed on Schedule 3.17 or
Schedule 3.18.1, or (z) normal increases with respect to Non-Contract Employees
in the ordinary course of business consistent with past practice, since
September 30, 1996 Eldorado has not increased the wages, salary, compensation,
pension, or other benefits or perquisites payable to any officer, employee or
director, granted any severance or termination pay, entered into any contract to
make or grant any severance or termination pay, or paid any bonus.

         3.13 COMPLIANCE WITH APPLICABLE LAWS. Except as disclosed in the
Securities Filings, the business of Eldorado is, and at all times since December
31, 1992 has been, conducted in compliance with all Laws (including those
relating to equal credit, fair lending, fair housing and community
reinvestment), except where a failure to so comply, individually or in the
aggregate, would not have a Material Adverse 

                                      A-14

APPENDIX A


Effect on Eldorado. Eldorado holds all Permits that are material to the
operation of its business, and is in compliance with the terms of each such
Permit except where the failure so to comply, individually or in the aggregate,
would not have a Material Adverse Effect on Eldorado. Except as disclosed on
Schedule 3.8 or Schedule 3.13, no investigation by any Governmental Entity with
respect to Eldorado is pending or, to Eldorado's Knowledge, contemplated.

         3.14 LITIGATION AND OTHER DISPUTES. Except as disclosed on Schedule
3.14, as of the date hereof there is no suit, action, or proceeding pending or,
to Eldorado's Knowledge, threatened, against or affecting Eldorado or any of its
assets, nor is there any judgment, decree, injunction, rule or order of any
Governmental Entity or arbitrator outstanding against Eldorado the obligations
under which have not heretofore been fully performed. Neither (a) any matter
disclosed on Schedule 3.14, nor (b) any suit, action or proceeding pending or
threatened as of the Closing Date, nor (c) any judgment, decree, injunction,
rule or order of any Governmental Entity outstanding against Eldorado as of the
Closing Date (and not fully performed prior to the date hereof) has had or could
reasonably be expected, if adversely determined, to have a Material Adverse
Effect on Eldorado. Except as disclosed on Schedule 3.14, since December 31,
1993, Eldorado has not been a defendant, either directly or as
defendant-in-counterclaim or cross-claim, in any material litigation in which
any "lender liability" cause of action was asserted against Eldorado.

         3.15 ADMINISTRATION OF FIDUCIARY ACCOUNTS. Eldorado has properly
administered in all material respects all accounts for which it acts as a
fiduciary, including but not limited to accounts for which it serves as a
trustee, agent, custodian, personal representative, guardian, conservator or
investment advisor, in accordance with the terms of the governing documents and
applicable state and federal law and regulation and common law. Neither Eldorado
nor any of its directors, officers or employees has committed any breach of
trust with respect to any such fiduciary account which, individually or in the
aggregate, has had or could reasonably be expected to have a Material Adverse
Effect on Eldorado, and the accountings for each such fiduciary account are true
and correct in all material respects and accurately reflect the assets of such
fiduciary account.

         3.16 TAXES. Eldorado has filed all tax returns it has been required to
file and Eldorado has paid or has set up an adequate reserve for the payment of
all Taxes required to be paid as shown on such returns, and the Most Recent
Financial Statements reflect an adequate reserve for all Taxes payable by
Eldorado accrued through the date of such financial statements. Except as set
forth on Schedule 3.16, no deficiencies for any Taxes have been proposed,
asserted or assessed against Eldorado that are not adequately reserved for. The
Federal income tax returns of Eldorado have been examined by and settled with
the IRS, or the statute of limitations with respect to each such year has
expired (and no waiver extending the statute of limitations has been requested
or granted), for all years through 1992. No audit or review is pending for any
of such years or for any subsequent year and, except as set forth on Schedule
3.16, to Eldorado's Knowledge no challenge or deficiency is contemplated by the
IRS with regard to any year. Except as set forth on Schedule 3.16, Eldorado has
not [(a) filed any consent to the application of Section 341(f) of the Internal
Revenue Code, (b) filed any election under Section 338(g) or 338(h)(10) of the
Internal Revenue Code or caused or permitted any deemed election under Section
338(e) of the Internal Revenue Code,] (c) applied for any revenue ruling,
private letter ruling or other ruling relating to Taxes, (d) entered into any
closing agreement with any Governmental Entity relating to Taxes, or (e) been,
at any time, a member of any affiliated group filing any consolidated tax return
other than the existing group consisting of Eldorado and the Bank.

         3.17 CERTAIN AGREEMENTS. Except as disclosed on Schedule 3.17, Eldorado
is not party to (nor are any of its assets bound by) any material oral or
written contract, lease or other agreement in effect as of

                                      A-15

annual report on Form 10-K filed with the SEC, (b) the benefits of which (to
either party) will accrue or be increased, or the vesting of the benefits of
which will be accelerated, by the occurrence of the Merger or the Bank Mergers
(either alone or upon the occurrence of any additional acts or events) or the
value of any of the benefits of which will be calculated on the basis of the
Merger or the Bank Mergers or any portion or aspect of either (including any
so-called retention or similar bonuses), (c) relating to employment, salary
continuation, severance, consulting (including data processing, software
programming and licensing contracts), collective bargaining or otherwise
relating to the provision of personal services or payment therefor, (d) which,

payment (whether of severance pay or otherwise) becoming due from Surviving
Corporation or the Bank to any officer or employee of the Surviving Corporation
or the Bank or formerly of Eldorado, (e) relating to non-competition or secrecy,
(f) that materially restricts the conduct of any line of business by Eldorado,
or (g) that was entered into in connection with the consummation of a federally
assisted acquisition of a depository institution pursuant to which Eldorado is
entitled to receive financial assistance or indemnification from any
Governmental Entity. Eldorado in not in Violation of any contract, lease or
other agreement described by any of the foregoing clauses (a) through (g) in an
manner that (i) could reasonably be expected to result in a termination of such
agreement or a claim for material damages by the other party thereto or (ii)
could reasonably be expected, individually or in the aggregate, to result in a
Material Adverse Effect on Eldorado, and to Eldorado's Knowledge, no other party
to any such contract, lease or other agreement has committed any such Violation
of the same. Except for agreements filed as part of the Securities Filings,
Eldorado has previously delivered to CSBI true and correct copies of each
agreement described by any of the foregoing clauses (a) through (g) that is in

agreement, a director, officer or holder of 3% or more of the Common Stock.

Bank any material payment (including bonuses and including those in the nature
of severance, salary continuation, unemployment compensation, golden parachute

                                      A-17
<PAGE>   109
APPENDIX A


under all leases of real or personal property under which it is operating or to
which it is a party. All of such leases are valid, subsisting and in full force
and effect and there are no existing defaults or events which, with the passage
of time or the giving of notice, or both, would constitute defaults by Eldorado
or, to Eldorado's knowledge, by any other party thereto, except for such
defaults, if any, which could not, individually or in the aggregate, reasonably
be expected to have a Material Adverse Effect. All items of real or personal
property owned or used by Eldorado and material to its business have been
properly maintained and, to Eldorado's Knowledge, are in good operating order
and repair.

     3.20  ENVIRONMENTAL. Except as disclosed on Schedule 3.20, Eldorado and all
real property (including OREO) in the possession of Eldorado are, and at all
times while in the possession of Eldorado each such property has been, in
compliance with all applicable Laws relating to pollution or protection of human
health or the environment (including Laws relating to emissions, discharges,
releases or threatened releases of Hazardous Material or otherwise relating to
the manufacture, processing, distribution, use, treatment, storage, disposal,
transport or handling of Hazardous Material), except for Violations that, either
individually or in the aggregate, have not had and would not reasonably be
expected to have a Material Adverse Effect on Eldorado. To Eldorado's Knowledge,
there has not occurred any release of Hazardous Material on, under or affecting
any real property during the period of Eldorado's ownership, possession or
operation of such property (including its participation in the management of any
business located on such property) or, to Eldorado's Knowledge, during any prior
period. Neither Eldorado nor any property now or heretofore in its possession is
or, while owned or in the possession of Eldorado, has ever been a defendant in
or the subject of any suit, claim, action, proceeding, investigation or written
notice or, to Eldorado's Knowledge, oral inquiry before or by any Governmental

any predecessor) of any environmental Law or relating to the release or
threatened release into the environment of any Hazardous Material, whether or
not occurring at or on a site owned, leased or operated by Eldorado.

     3.21  INTELLECTUAL PROPERTY. Eldorado either owns or possesses valid and
binding licenses and other rights to use all material trademarks, trade names,
servicemarks, copyrights, trade secrets and patents used in its businesses. The
only such licenses or other rights to use intellectual property that require
payment by Eldorado are licenses for the use of software and similar property
entered into by Eldorado in the ordinary course of business. Eldorado has not
received any written challenge to its ownership of, or other right to use, any
such intellectual property by any Person or any notice of alleged conflict
between the same and the rights of any other Person. Eldorado has, in all
material respects, performed all of its obligations under, and is not in
material Violation of, any contract, agreement, arrangement or commitment
relating to any of the foregoing.

     3.22  BROKERS. Eldorado has not employed any broker, finder or similar
Person in connection with the Merger other than Alex Sheshunoff & Co., and has
not incurred and will not incur any broker's, finder's or similar fees,

Sheshunoff & Co., addressed to the Board of Directors, to the effect that as of
the date hereof the Merger Consideration is fair, from a financial point of
view, to the holders of the Common Stock.

<PAGE>   111
APPENDIX A


Agreement and the consummation of the Merger have been duly authorized by all
necessary action on the part of CSBI, including approval by its board of
directors. This Agreement has been duly executed and delivered by CSBI and
(assuming due authorization, execution and delivery by Eldorado) constitutes the
valid and binding obligation of CSBI, enforceable against CSBI in accordance

proceeding at law or in equity).

     4.4   NO CONFLICTS. Neither the execution and delivery of this Agreement
nor the consummation of the Merger will conflict with or result in any Violation
of any provision of the Certificate of Incorporation or By-laws of CSBI. Subject
to obtaining or making the consents, approvals, orders, authorizations,
registrations, declarations and filings referred to in Section 4.5, neither the
execution and delivery of this Agreement nor the consummation of the Merger will

in connection with the execution and delivery of this Agreement by CSBI, or the
consummation of the Merger by Merger Sub, as to which the failure to obtain the
same would have a Material Adverse Effect on CSBI or materially interfere with
Merger Sub's ability to consummate the Merger or CSBI's ability to cause Merger
Sub to consummate the Merger.

     4.6   SECURITIES FILINGS, FINANCIAL STATEMENTS AND FINANCIAL CONDITION. The
consolidated financial statements of CSBI included in CSBI's Form 10-Q filed

Merger Financing, will be well capitalized as of the Closing.

contemplating issuing or requesting (or considering the appropriateness of
issuing or requesting) any such Regulatory Agreement. Except as disclosed on
Schedule 4.7, there exists no material unresolved violation, criticism or
exception identified by any Bank Regulator with respect to any report or
statement of CSBI, or relating to any examination of CSBI.

     4.8   ABSENCE OF UNDISCLOSED LIABILITIES, CERTAIN CHANGES OR EVENTS. Except
(a) as and to the extent reflected in CSBI's Form 10-Q filed with the SEC for
the period ended September 30, 1996, (b) obligations (including guarantees and
letters of credit) not required by GAAP to be reflected, reserved against or
disclosed in such Form 10-Q, none of which obligations, individually or in the
aggregate, could reasonably be expected to have a Material Adverse Effect on
CSBI, and (c) obligations incurred in the ordinary course of business consistent
with past practice since the Most Recent Balance Sheet Date, CSBI does not have
any liabilities, commitments or obligations of any nature, whether absolute,
accrued, contingent or otherwise, and whether due or to become due, which relate
to transactions entered into, or any state of facts existing, on or before the
date hereof and which would be required under GAAP to be shown on an audited
balance sheet as of the date hereof or referenced in notes thereto if such
balance sheet or notes existed. Since the Most Recent Balance Sheet Date, no
event or development has occurred that, individually or in the aggregate, has
had or could reasonably be expected to have a Material Adverse Effect on CSBI,
and CSBI has carried on its business in the ordinary and usual course consistent
with its past practices.

     4.9   COMPLIANCE WITH APPLICABLE LAWS. Except as disclosed in any report,
schedule, registration statement or definitive proxy statement filed with the
SEC or the Office of the Comptroller of the Currency (as applicable) pursuant to
the Exchange Act since January 1, 1994 by CSBI or, to CSBI's knowledge, any CSBI
Subsidiary Predecessor (as such documents have been amended since the time of
their filing), the business of CSBI is, and at all times since December 31, 1992
the business of CSBI and, to CSBI's knowledge, the business of each CSBI
Subsidiary Predecessor, has been conducted in compliance with all Laws
(including those relating to equal credit, fair lending, fair housing and
community reinvestment), except where a failure to so comply, individually or in
the aggregate, would not have a Material Adverse Effect on CSBI. CSBI holds all
Permits that are material to the operation of its business, and is in compliance
with the terms of each such Permit except where the failure so to comply,
individually or in the aggregate, would not have a Material Adverse Effect on
CSBI. Except as disclosed on Schedule 4.5 or Schedule 4.6, no investigation by
any Governmental Entity with respect to CSBI is pending or, to CSBI's Knowledge,
contemplated.

     4.10  BROKERS. CSBI has not employed any broker, finder or similar Person
in connection with the Merger other than Carpenter & Company, and has not
incurred and will not incur any broker's, finder's or similar fees, commissions
or expenses in connection with the Merger other than those of Carpenter &
Company and (to the extent deemed to be in connection with the Merger) those of
any placement agent or similar Person employed in connection with the Merger
Financing, each of whose fees shall be borne entirely by CSBI.

     4.11  FINANCIAL CAPACITY.  CSBI has delivered to Eldorado true and correct
copies of (a) a commitment letter relating to investments in CSBI in the
aggregate amount of $63,300,000 and (b) certain subscription agreements each
relating to investments in CSBI in the aggregate amount of not less than


                                      A-21
<PAGE>   113
APPENDIX A


$18,000,000. All representations made to CSBI's sources of Merger Financing in
the applicable subscription agreements or securities purchase agreements are (or
when such agreements are executed, will be) true and correct in all material
respects as of the date of each such representation or warranty. Notwithstanding
the foregoing, the obligations of CSBI hereunder are not conditioned upon its
obtaining financing.


                                    ARTICLE V
                              ADDITIONAL AGREEMENTS

     5.1   DISCUSSIONS WITH THIRD PARTIES.

          5.1.1 Until the earlier of the Effective Time or the termination of
this Agreement, Eldorado (a) shall not, and shall instruct its Representatives
not to, solicit or encourage, directly or indirectly, inquiries or proposals
with respect to any Strategic Transaction Proposal, and (b) except as expressly
permitted by Section 5.1.2 or Section 5.1.3, shall not, and shall instruct its
Representatives not to, furnish any non-public information relating to or
participate in any negotiations, discussions or other activities concerning, any
Strategic Transaction with any Person other than CSBI and Merger Sub. Eldorado
shall notify CSBI promptly after any Strategic Transaction Proposal is received
by, or any negotiations or discussions regarding a Strategic Transaction
Proposal are sought to be initiated (or continued) with, directly or indirectly,
Eldorado or any of its Representatives, and shall disclose to CSBI the identity
of the third party making or seeking to make such Strategic Transaction
Proposal, the terms and conditions of such Strategic Transaction Proposal and
such other information as CSBI reasonably may request; provided, however, that
if Eldorado receives a Strategic Transaction Proposal and the foregoing
disclosure of such Proposal to CSBI would violate a confidentiality agreement by
which Eldorado is bound, Eldorado (a) shall make the foregoing disclosure only
to the maximum extent permissible under such confidentiality agreement, (b)
shall return such Strategic Transaction Proposal to the initiating party without
substantive response (together with, if so elected by Eldorado, a copy of this
Section 5.1), and (c) to the extent such disclosure has not been made under
clause (a), shall notify CSBI that a Strategic Transaction Proposal has been
received and that the same has been returned to the initiating party without
substantive response. Without limiting the foregoing, it is understood and
agreed that any failure by any of Eldorado's Representatives to abide by the
limitations set forth in this Section 5.1 shall constitute a breach of this
Section 5.1 by Eldorado regardless of whether such Representative's actions were
authorized by or purported to be undertaken on behalf of Eldorado.

          5.1.2 Notwithstanding Section 5.1.1 or any other provision of this
Agreement to the contrary, in the event that, on an entirely unsolicited basis,
Eldorado receives a Strategic Transaction Proposal from a third party, and
Eldorado's counsel advises the Board of Directors that the Directors' fiduciary
duties owed to the Shareholders obligate the Board to furnish non-public
information to the third party having submitted such Proposal, then Eldorado
shall not be prohibited from furnishing to such third party, either directly or
to or through its Representatives, information that was previously provided or
made available to CSBI (or, if not previously requested by CSBI and therefore
not previously provided, that is contemporaneously provided to CSBI) or from
answering questions regarding the information so furnished (but not about the
terms of any possible Strategic Transaction), provided that the third party
shall have entered into a confidentiality agreement substantially similar to the
confidentiality provisions of Section 5.3 hereof, or from seeking clarifications
regarding (but not conducting negotiations regarding) the terms of such Proposal
or the consideration contemplated therein or information regarding the Person
making such Proposal.

APPENDIX A


          5.1.3 Notwithstanding Section 5.1.1 or any other provision of this
Agreement to the contrary, following receipt of a Qualifying Strategic
Transaction Proposal, neither Eldorado nor any of its Representatives shall be
prohibited from taking, nor shall it be a breach of this Agreement for Eldorado
or any of its Representatives to take, any of the following actions with respect
to a Strategic Transaction Proposal: (a) engaging in discussions or negotiations
with a third party which has made a proposal that satisfies the requirements of
a Qualifying Strategic Transaction Proposal, (b) taking and disclosing to the
Shareholders a position contemplated by Rule 14e-2 under the Exchange Act or
otherwise making disclosure of the Qualifying Strategic Transaction Proposal to
the Shareholders, (c) taking any of the actions described in Section 5.2.2 or
(d) subject to the terms of Article VII, terminating this Agreement. A
"Qualifying Strategic Transaction Proposal" shall mean a bona fide written
Strategic Transaction Proposal (which Proposal may be conditional) that (x) is
delivered to the Board of Directors (whether directly or through a
Representative of Eldorado), (y) identifies a price or range of values to be
paid for the capital stock, assets or liabilities of Eldorado or the Bank that
are to be sold or otherwise transferred pursuant to such Proposal, and (z) in
the good faith determination of the Board of Directors of Eldorado, based on the
advice of Eldorado's counsel and on a written opinion of Eldorado's investment
bankers to the effect that such Proposal is financially more favorable to the
Shareholders than the terms of the Merger (including due to a higher price or
range of values offered by such Proposal), requires the Board of Directors to
take (or cause Eldorado to take) one or more of the actions described in clauses
(b) through (e) of the immediately preceding sentence in order to comply with
the Board of Directors' fiduciary duties owed to the Shareholders.

          5.1.4 In the event that Eldorado receives a Qualifying Strategic
Transaction Proposal, it shall not accept or enter into any agreement which
provides for the consummation of the Strategic Transaction described in such
Proposal for a period of at least 72 hours after the delivery to CSBI of a copy
of such Proposal. Upon compliance with the foregoing and termination of this
Agreement pursuant to Section 7.4.2 hereof (including the payment in full to
CSBI of the Termination Fee as provided in Section 7.6.3), Eldorado may enter
into any agreement that provides for the consummation of such Qualifying
Strategic Transaction. If, within twenty (20) calendar days following Eldorado's
receipt of a Qualifying Strategic Transaction Proposal, Eldorado has neither (i)
given notice to CSBI reaffirming Eldorado's intent to proceed under this
Agreement and to consummate the Merger, or (ii) terminated this Agreement
pursuant to Section 7.4.2, CSBI may at any time within thirty (30) days after
the close of such period terminate this Agreement pursuant to Section 7.3.2.

          5.1.5 Eldorado shall be entitled to provide copies of this Section 5.1
to third parties who, on an entirely unsolicited basis after the date hereof,
contact Eldorado to express their interest in a possible Strategic Transaction
with Eldorado or the Bank, provided that CSBI shall concurrently be notified of
such contact and the delivery of such copy.

APPENDIX A


     5.2   PROXY STATEMENT; SHAREHOLDER MEETING.

          5.2.1 Eldorado shall use all reasonable efforts to prepare and
distribute the Proxy Statement to the Shareholders as promptly as practicable,
to duly call, give notice of, convene and hold a meeting of the Shareholders to
be held as soon as is reasonably practicable thereafter for the purpose of
voting upon the approval of the Merger (including any adjournments thereof, the
"Shareholder Meeting"), and at such meeting (including any adjournments thereof)
to obtain the Shareholders' approval of the Merger. Except as expressly provided
in Section 5.2.2, the Proxy Statement shall include a Recommendation of Approval
by the Board of Directors, and shall further include the fairness opinion
referenced in Section 3.23 as an exhibit thereto. Eldorado shall use all
reasonable efforts to prepare and file the preliminary Proxy Statement with the
SEC within twenty-five (25) Business Days after the date of this Agreement.
Eldorado shall deliver to CSBI and afford CSBI an opportunity to comment on
drafts of the Proxy Statement prior to the filing of the preliminary Proxy
Statement with the SEC and prior to the distribution of the definitive Proxy
Statement to Shareholders, provided that (a) the period within which the
preliminary statement must be filed with the SEC shall be extended by a number
of Business Days in excess of five (5) elapse between the date that a
substantially complete draft thereof is forwarded to CSBI and the date that CSBI
furnishes its comments on such draft, and (b) if CSBI has failed to furnish
comments within ten (10) Business Days of its receipt of the applicable
materials, Eldorado shall be free to file the preliminary Proxy Statement or
distribute the definitive Proxy Statement, as applicable. None of the
information included, directly or by incorporation by reference, in the Proxy
Statement will, at the date of mailing to the Shareholders or at any time
through the time of the Shareholder Meeting, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading; provided, however,
that Eldorado makes no representations regarding any information supplied to
Eldorado by CSBI. The Proxy Statement will comply as to form in all material
respects with the applicable provisions of the Exchange Act and the rules and
regulations thereunder. CSBI shall cooperate in all reasonable respects with
Eldorado in the preparation of the Proxy Statement, including by making
available to Eldorado all information regarding CSBI that Eldorado reasonably
may request and that is reasonably necessary or appropriate for inclusion in or
for the preparation of the Proxy Statement. CSBI hereby represents and warrants
that no statement of fact relating to CSBI or Merger Sub that is made in writing
by CSBI to Eldorado for inclusion in the Proxy Statement, and that is in fact so
included, will be false or misleading in any material respect or will omit to
state a material fact necessary in order to make the statements made, in the
light of the circumstances under which they were made or disclosed, not
misleading. Eldorado shall use its best efforts to take all action necessary for
the Merger not to be subject to any state anti-takeover statute.

          5.2.2 In the event that Eldorado has received a Strategic Transaction
Proposal and the Board of Directors has determined, in accordance with Section
5.1.3, that such Strategic Transaction Proposal constitutes a Qualifying
Strategic Transaction Proposal, then the Board of Directors shall not be
prohibited from taking, nor shall it be a breach of this Agreement if it takes,
any of the following actions: (a) failing to include a Recommendation of
Approval in the Proxy Statement, (b) retracting or qualifying its Recommendation
of Approval if previously given, or (c) postponing or adjourning the meeting of
Shareholders called for the purpose of approving the Merger.

     5.3   ACCESS. Eldorado shall make available to CSBI all information
regarding Eldorado that CSBI reasonably may request and shall authorize all
reasonable visits to Eldorado's premises with such staff, consultants and
experts as CSBI reasonably may request. CSBI agrees to coordinate closely all
such activities with Eldorado's President or Chief Financial Officer and to
conduct any such inquiries with 


                                      A-24
<PAGE>   116
APPENDIX A


appropriate discretion and sensitivity to Eldorado's relationships with its
employees, customers and suppliers. The Parties acknowledge that certain of the
information made available to one another pursuant to this Section 5.3 and
otherwise in connection with the Merger may be confidential, proprietary or
otherwise nonpublic, and each Party agrees, for itself and for each of
Representatives, that it (i) shall hold in confidence all confidential
information received by it from or with regard to the other Party ("Confidential
Information") subject to the terms of this Section 5.3, (ii) shall disclose such
Confidential Information only to those of its Representatives and, in the case
of CSBI, its current or prospective investors and other sources of capital, in
each case having a need to know the same for purposes of evaluating, negotiating
or implementing the financing of the Merger, and (iii) shall inform each
Representative or current or prospective investor to whom Confidential
Information is disclosed that such information is confidential and shall obtain
from such Representative or investor a confidentiality agreement in
substantially the form previously provided by CSBI to Eldorado. Each Party shall
remain responsible for any disclosure of Confidential Information by any of its
Representatives or investors. Each Party further agrees that, upon the request
of the other Party given following any termination of this Agreement, it and
each of its Representatives either shall return to such other Party all
Confidential Information received by it and its Representatives (including all
compilations, analyses or other documents prepared by it that contain
Confidential Information) or shall certify that the same has been destroyed. As
used herein, Confidential Information shall not include (i) information that is
or becomes generally available to the public other than as a result of a breach
of this Agreement, (ii) information that the receiving Party demonstrates was
known to it on a non-confidential basis prior to receiving such information from
the other Party, (iii) information that the receiving Party develops
independently without relying on Confidential Information, and (iv) information
that becomes available to the receiving Party on a non-confidential basis from
another source if the source was not known to be, and not reasonably believed by
the receiving Party to be, subject to any prohibition against disclosing such
information.

     5.4   COOPERATION. The Parties shall cooperate with each other and use all
commercially reasonable efforts to prepare and file promptly all necessary
documentation, to effect all applications, notices, petitions and filings, and
to obtain as promptly as practicable all permits, consents, approvals and
authorizations of all third parties and Governmental Entities which are
necessary or advisable to consummate the Merger. The Parties agree that they
will consult with each other with respect to the obtaining of all permits,
consents, approvals and authorizations of all third parties and Governmental
Entities necessary or advisable to consummate the Merger and the Bank Mergers,
and each Party will keep the other apprised of the status of matters relating to
completion of the Merger and the Bank Mergers. Each Party shall, upon request,
furnish the other Party with all information concerning itself as may be
reasonably necessary or advisable in connection with any filing or application
made by or on behalf of such Party to any Governmental Entity in connection with
the Merger or the Bank Mergers. Each Party shall promptly advise the other Party
upon receiving any communication from any Governmental Entity whose consent or
approval is required for consummation of the Merger or the Bank Mergers which
causes such Party to believe that there is a reasonable likelihood that any
required Governmental Approval will not be obtained or that the receipt of any
such Governmental Approval will be materially delayed. Eldorado shall cooperate
with CSBI in all reasonable respects, upon the request of CSBI, in CSBI's
finalization of its financing of the Merger, including by furnishing all
information reasonably requested in connection therewith.

     5.5   ADVICE OF CHANGES. Each Party shall promptly advise the other Party
of any change or event having a Material Adverse Effect on it or its ability to
perform its obligations under this Agreement or which it believes would or may
be reasonably likely to cause or constitute a material breach of any of its
representations, warranties or covenants contained herein or to preclude the
satisfaction of one or more of the conditions set forth in Article VI. From time
to time prior to the Closing Date, Eldorado will promptly supplement or amend
the Disclosure Schedules to reflect any matter which, if existing, occurring or
known 


                                      A-25
<PAGE>   117
APPENDIX A


at the date of this Agreement, would have been required to be set forth or
described in such Disclosure Schedules, or which is necessary to correct any
information in such Disclosure Schedules which has been rendered inaccurate
thereby (each notice furnishing such information being called a "Disclosure
Supplement"); provided, however, that any such Disclosure Supplement which
reports events, developments or changes that have occurred subsequent to the
date hereof shall not constitute a breach of any representations and warranties
of Eldorado but also shall not have any effect for the purpose of determining
the accuracy of any representation or warranty when made, for determining
satisfaction of the conditions set forth in Article VI, or for determining the
compliance by Eldorado with any other provision of this Agreement; provided
further, that (a) except as provided in the immediately following sentence,
unless CSBI notifies Eldorado that CSBI elects to terminate this Agreement
pursuant to Section 7.3.1 or Section 7.3.3 on the basis of the events or
conditions disclosed in such Disclosure Supplement within twenty (20) Business
Days after the date of CSBI's receipt thereof (the "Notification Date"), CSBI
shall thereafter be deemed to have waived any right of termination attributable
solely to such events or conditions, but (b) for purposes of determining the
satisfaction of the condition set forth in Section 6.2.2, no such waiver shall
exist (i) with respect to the cumulation of such events or conditions with other
events or conditions requiring disclosure under the same representation or
warranty and described in any subsequent Disclosure Supplement or otherwise
discovered by CSBI or (ii) if there is a further material adverse development in
the event or condition so disclosed. Notwithstanding the foregoing clause (a)
if, in the reasonable opinion of CSBI, the information provided in such
Disclosure Supplement is insufficient for CSBI to evaluate fully whether the
identified event or condition constitutes or contributes to a failure of the
condition to closing set forth in section 6.2.1, then with respect to such event
or condition, the Notification Date may be extended, at the election of CSBI,
until such date as CSBI has received from Eldorado sufficient information to
make the evaluation contemplated by this sentence. In order to so extend the
Notification Date, CSBI must provide Eldorado with written notice of such
extension not later than the initial Notification Date, which notice shall (x)
specify each event or condition as to which the extension is being made, and (y)
set forth in reasonable detail the information that CSBI requires in order to
make the evaluation of each such event or condition as contemplated by the
immediately preceding sentence.

     5.6   CURRENT INFORMATION. During the period from the date of this
Agreement to the Closing Date, Eldorado will cause one or more of its designated
representatives to confer on a regular and frequent basis (not less than
bi-weekly) with representatives of CSBI and to report the general status of the
ongoing operations of Eldorado. Eldorado will promptly notify CSBI of (a) any
material adverse change in the normal course of business or in the operation of
the properties of Eldorado, (b) any governmental complaint, investigation or
hearing (or communications indicating that the same may be contemplated), or (c)
the institution or the threat of material litigation involving Eldorado, and
will keep CSBI fully informed of such events. Eldorado will keep CSBI fully
informed of the status of, and the action proposed to be taken with respect to,
Classified Assets that, in combination with all related Borrower Group
Obligations, have an aggregate carry value of $100,000 or more. Eldorado will
provide to CSBI copies of the minutes (or consents in lieu of meeting) of its
loan committee, its Board of Directors and all committees thereof promptly
following each such meeting; provided, however, that Eldorado may omit therefrom
any portion of such minutes that it determines, with the concurrence of its
counsel, relates to (a) the Parties' compliance or non-compliance with the terms
of this Agreement, or (b) any Strategic Transaction Proposal other than the
Merger or (c) any matter which is subject to an attorney-client privilege.

     5.7   INTERIM AND ANNUAL FINANCIAL STATEMENTS. As soon as reasonably
available, but in no event more than 45 days after the end of each fiscal
quarter ending after the date of this Agreement and prior to the Closing Date
(excepting the quarter ending December 31, 1996), Eldorado will deliver to CSBI
its 


                                      A-26
<PAGE>   118
APPENDIX A


Quarterly Reports on Form 10-Q as filed with the SEC, and as soon as reasonably
available, but in no event later than March 31, 1997 (provided that the Closing
has not yet occurred and the Agreement has not theretofore been terminated),
Eldorado will deliver to CSBI its Annual Report on Form 10-K for the period
ending December 31, 1996, as filed with the SEC. Eldorado will deliver to CSBI
monthly financial statements (the "Monthly Financial Statements") no later than
the time at which such financial statements are delivered to such Directors but
in no event later than the twenty-first calendar day of the month immediately
following the month to which such financial statements relate. When delivered,
the Monthly Financial Statements will present fairly, in all material respects,
the financial condition of Eldorado and its results of operations as at and for
the period then ended, will reflect in all respects GAAP accounting treatment of
the matters contained therein (except as expressly noted thereon), and will be
prepared in the manner and in the form customarily delivered to the Board of
Directors.

     5.8   CONDUCT OF BUSINESS BY ELDORADO. Subject to Section 5.1, Eldorado
shall (a) conduct its business in the usual, regular and ordinary course of
business consistent with past practice (except as required by applicable Law or
by this Agreement), (b) use all reasonable efforts to maintain and preserve
intact its business organization, employees and advantageous business
relationships and retain the services of its officers and key employees
(including by causing its current insurance policies not to be cancelled or
terminated or any of the coverage thereunder to lapse prior to or upon the
Closing or closing of the Bank Mergers, unless simultaneously with such event
replacement policies providing substantially similar coverage for substantially
similar (or lesser) premiums are in full force and effect), (c) conduct
relations with its employees, including hiring and terminating practices, only
in the ordinary course of business and consistent with past practice, and (d)
take no action which would adversely affect or delay the ability of Eldorado or
CSBI or any of their respective direct or indirect subsidiaries to obtain any
necessary approvals of any Governmental Entity required for the Merger or for
the transactions contemplated in connection therewith, or to perform its
covenants and agreements under this Agreement.

     5.9   CERTAIN OPERATING COVENANTS.  Without CSBI's prior written consent
(which consent, in the case of Sections 5.9.9 through 5.9.14, shall not be
unreasonably withheld or delayed), Eldorado shall not, and in the case of
Section 5.9.7, the Eldorado officers identified in the definition of "Eldorado's
Knowledge" shall not:

          5.9.1 declare or make any payment or distribution with respect to the
capital stock or other securities of Eldorado Bancorp, whether by way of payment
of interest or principal, redemption, dividend or otherwise, excepting regular
quarterly cash dividend payments on the Common Stock, with such record dates and
at such amounts per share as are set forth on Schedule 5.9.1 (provided that the
applicable record date is not later than the date anticipated for the Closing at
the time such dividend would otherwise have been declared) and declared by the
Board of Directors no earlier than the declaration date set forth on Schedule
5.9.1 opposite the applicable record date; provided, however, that if any
dividend so declared as of to the Closing Date has not been paid prior to the
Closing Date, Eldorado may deliver adequate funds for the payment of the same to
its stock transfer agent prior to the Closing Date, for payment to the
Shareholders entitled thereto on or before the scheduled payment date;

          5.9.2 (a) create, authorize, issue, sell or deliver any of its capital
stock, bonds or other of its securities (whether authorized and unissued or held
in treasury) or any instrument convertible into any of them, excepting only by
the issuance of shares of Common Stock upon the exercise of one or more
currently outstanding Options in accordance with the present terms of such
Option; (b) grant or otherwise issue any options, warrants or other rights with
respect thereto; (c) amend the terms of any currently outstanding option

APPENDIX A


(including any Option), warrant or other right with regard to Eldorado's
securities; or (d) split up, combine or reclassify any of its outstanding stock;

          5.9.3 acquire, by merging or consolidating with, by purchasing a
substantial equity interest in or a substantial portion of the assets of, or by
any other manner, any business, including any corporation, partnership,
association or other business organization or division thereof;

          5.9.4 excepting those matters identified on Schedule 5.9.4,

                (a)  create, renew, amend or terminate, or give notice of a
proposed renewal, amendment or termination of, (i) any material contract,
agreement or lease for goods, services or office space to which Eldorado is (or
would thereby be) a party or by which Eldorado or any of its properties is (or
would thereby be) bound, excepting only contracts, agreements and leases under
which the aggregate payments by either party over the term of the agreement do
not exceed $50,000 (or, if indefinite, are not reasonably expected to exceed
$50,000), (ii) any agreement the benefits of which (to either party) will accrue
or be increased, or the vesting of the benefits of which will be accelerated, by
the occurrence of the Merger or the Bank Mergers (either alone or upon the
occurrence of any additional acts or events) or the value of any of the benefits
under which will be calculated on the basis of the Merger or the Bank Mergers or
any portion or aspect of either (including any so-called retention or similar
bonuses), (iii) any agreement relating to non-competition or secrecy, or (iv)
any agreement that materially restricts the conduct of any line of business by
Eldorado,

                (b)  make any single capital expenditure exceeding $25,000 or
any capital expenditures exceeding $100,000 in the aggregate, or

                (c)  relocate or terminate, or file any application to relocate
or terminate, the operations of any of its banking offices (including loan
production offices);

          5.9.5 enter into any new line of business;

          5.9.6 change its methods of accounting in effect at December 31, 1995,
except as required by changes in GAAP or RAP as concurred with by Eldorado's
independent auditors;

          5.9.7 fail to use all reasonable efforts to prevent Eldorado from
committing a Violation of any Law, Regulatory Agreement or any material contract
or license to which Eldorado is a party or by which it or any of its properties
is bound, which Violation, individually or in the aggregate, has or reasonably
could be expected to have a Material Adverse Effect on Eldorado.

          5.9.8 make any equity investment in any real estate or real estate
development project, other than (a) additional investments in existing projects
as set forth on Schedule 5.9.8, or (b) in connection with foreclosures,
settlements in lieu of foreclosure or troubled loan or debt restructurings in
the ordinary course of business consistent with prudent banking practices;
          
          5.9.9 sell, lease, assign, transfer or otherwise dispose of any
property or asset, except for (a) investment portfolio transactions in the
ordinary course of business and substantially consistent with past practice; (b)
sales, in the ordinary course of business, of SBA Loans (or portions of such
loans) under which the final disbursement was made after the Most Recent Balance

applications necessary to obtain the CSBI Governmental Approvals (using all
reasonable efforts to file the same in draft or preliminary form no later than

     5.11  COVENANTS REGARDING EMPLOYEES, DIRECTORS AND OFFICERS.

          5.11.1 Employee Benefit Plans.

           (a)   From and after the Effective Time, and subject to applicable
law, CSBI shall provide employee benefits, including those under Benefit Plans,
to those of its (including its subsidiaries') employees who formerly were
employees of Eldorado substantially the same as the benefits provided to
similarly situated employees of CSBI. From and after the Effective Time,
employees of CSBI (including its subsidiaries) who were employees of Eldorado
immediately prior to the Effective Time shall receive full credit for all
purposes under such plans for their years of service at Eldorado and (any
predecessors thereto) prior to the Effective Time.

           (b)   CSBI shall honor in accordance with their terms (i) all
Eldorado Benefit Plans and (ii) all contracts, arrangements and commitments
described in Section 3.17(c) that are disclosed on Schedule 3.17 and (iii) all
benefits vested thereunder as of the Effective Time; provided, however, that
nothing in this sentence shall be interpreted as preventing CSBI from amending,
modifying or terminating any Eldorado Benefit Plans, contracts, arrangements or
commitments in the manner and to the extent permitted by the terms thereof.

          5.11.2 Indemnification; Directors' and Officers' Insurance.

          (a)    In the event of any threatened or actual claim, action, suit,
proceeding or investigation, whether civil, criminal or administrative,
including any such claim, action, suit, proceeding or investigation in which any
person who is now, or has been at any time prior to the date of this Agreement,
or who becomes prior to the Effective Time, a director or officer or employee of
Eldorado (including any of its subsidiaries) (the "Indemnified Parties") is, or
is threatened to be, made a party based in whole or in part on, or arising in
whole or in part out of, or pertaining to (i) the fact that he or she is or was
a director, officer or employee of Eldorado or any of its predecessors, or (ii)
this Agreement or any of the transactions contemplated hereby, in any case
whether asserted or arising before or after the Effective Time, the Parties
hereto agree to cooperate and use their best efforts to defend against and
respond thereto.

          (b)    After the Effective Time, and for a period of six years
thereafter, CSBI shall indemnify and hold harmless and defend, each such
Indemnified Party against any losses, claims, damages, liabilities, costs,
expenses (including reasonable attorney's fees and expenses in advance of the
final disposition of any claim, suit, proceeding or investigation to each
Indemnified Party to the fullest extent Eldorado's directors are so indemnified
under the Eldorado Indemnification Rights as of the date hereof),

APPENDIX A


judgments, fines and amounts paid in settlement in connection with any such
threatened or actual claim, action, suit, proceeding or investigation, whether
civil, criminal, administrative or investigative, arising out of or pertaining
to any action or omission that occurred, or has been alleged to have occurred,
at any time prior to the Effective Time or the respective times they cease be
directors or officers of Eldorado or the Bank (as applicable), whichever is
later, or arising out of or pertaining to this Agreement or the other agreements
entered into or approved by the Eldorado Directors in connection with the
transactions contemplated by this Agreement (specifically including the
implementation of any modification, change or adjustment pursuant to Section
5.13.2) (collectively, the "Indemnified Liabilities, Expenses and Claims"), in
each instance as and to the fullest extent that the directors of Eldorado, as of
the date hereof, would be entitled to be indemnified by Eldorado or the Bank
pursuant to their respective Articles of Incorporation and under whichever of
the respective Bylaws, or the Indemnification Agreements, as in effect on the
date hereof, would provide such directors with the most extensive
indemnification rights (hereinafter the "Eldorado Indemnification Rights"), with
respect to such Indemnified Liabilities, Expenses and Claims if they had arisen
prior to the Effective Time. In the event of any such threatened or actual
claim, action, suit, proceeding or investigation (whether asserted or arising
before or after the Effective Time), the Indemnified Parties may retain counsel
reasonably satisfactory to them after consultation with CSBI; provided, however,
that (i) except as otherwise provided hereinafter, CSBI shall have the right to
assume the defense thereof with counsel reasonably acceptable to the Indemnified
Parties, and upon such assumption CSBI shall not be liable to any Indemnified
Party for any legal expenses of other counsel or any other expenses subsequently
incurred by any Indemnified Party in connection with the defense thereof, except
that if counsel for the Indemnified Parties reasonably advises the Indemnified
Parties that there are issues which raise conflicts of interest between CSBI and
the Indemnified Parties or among the Indemnified Parties, the Indemnified
Parties may retain counsel reasonably satisfactory to them after consultation
with CSBI, and CSBI shall pay the reasonable fees and expenses of such counsel
for the Indemnified Parties, (ii) CSBI shall be obligated pursuant to this
paragraph to pay for only one firm of counsel for all Indemnified Parties in the
absence of a conflict of interest (determined as described above) among the
Indemnified Parties in each jurisdiction in which any such claim, actions, suit,
proceeding or investigation is brought, and shall be obligated pursuant to this
paragraph to pay for no more than two firms of counsel among all Indemnified
Parties in each such jurisdiction in the event of a conflict of interest
(determined as described above) among the Indemnified Parties, (iii) CSBI shall
not be liable for any settlement effected without its prior written consent,
which it shall not unreasonably withhold, (iv) CSBI shall have no obligation
hereunder to any Indemnified Party when and if a court of competent jurisdiction
shall ultimately determine, and such determination shall have become final and
nonappealable, that indemnification of such Indemnified Party in the manner
contemplated hereby is prohibited by applicable Law and such Law makes
unenforceable the indemnity otherwise provided hereunder or under the
Indemnification Agreements, and (v) CSBI shall have no obligation hereunder to
any Indemnified Party with respect to any threatened or actual claim, action,
suit, proceeding or investigation, or any loss or expense caused thereby,
arising out of any action (or failure to act) that has been determined by a
judgment of a court having competent jurisdiction and that has been final and
non-appealable to have been a material breach of this Agreement, provided that
CSBI proves that such act or omission was intentionally or recklessly committed
by such Indemnified Party. Unless and until there shall be a final judicial
determination that a person who is otherwise an Indemnified Party is not
entitled to indemnification hereunder with respect to a given claim or
proceeding, CSBI shall advance all expenses with respect to which an Indemnified
Party is entitled to indemnity hereunder by paying the same to the Indemnified
Party or to the counsel or other Person to whom they are owed within twenty (20)
days following delivery of a written request therefor by such Indemnified Party
to CSBI. Each Indemnified Party with respect to whom expenses have been so
advanced hereby undertakes to repay such amount advanced only if, and to the
extent that, it shall ultimately be determined that such Indemnified Party is
not entitled to be indemnified by CSBI pursuant to this Section 5.11. Any
Indemnified Party wishing to claim indemnification under this Section 5.11.2,
upon learning of 


                                      A-31
<PAGE>   123
APPENDIX A


any such claim, action, suit, proceeding or investigation, shall notify CSBI
thereof, provided that the failure to so notify shall not affect the obligations
of CSBI under this Section 5.11.2 except to the extent such failure to notify
materially prejudices CSBI. CSBI's obligations under this Section 5.11.2
continue in full force and effect for a period of six (6) years from the
Effective Time and, with respect only to any claim asserted or made prior to or
within such period, thereafter until the final disposition of such claim.

           (c)   CSBI shall use its best efforts to cause the persons serving as
officers and directors of Eldorado or the Bank immediately prior to the
Effective Time, and any former officers or directors thereof who were covered by
directors and officers' liability insurance maintained by Eldorado or the Bank
immediately prior to the Effective Time, to be covered for a period of six (6)
years from the Effective Time by the directors' and officers' liability
insurance policy maintained by Eldorado (provided that CSBI may substitute
therefor policies of at least the same coverage and amounts containing terms and
conditions which are not less advantageous than such policy) with respect to
acts or omissions occurring, or alleged to have occurred, prior to the Effective
Time of such officers and directors in their capacity as such; provided,
however, that in no event shall CSBI be required to expend more than 200% of the
current amount expended by Eldorado to maintain or procure insurance coverage
pursuant hereto and further provided that if CSBI is unable to maintain or
obtain the insurance called for by this Section 5.11.2(c), CSBI shall obtain as
much comparable insurance as available for an amount equal to 200% of the amount
currently expended therefor by Eldorado.

           (d)   For a period of six years after the Effective Time, the
Surviving Corporation and CSBI will fulfill and honor in all respects the
obligations of Eldorado or the Bank, as the case may be, pursuant to
indemnification agreements in existence at the date of this Agreement that
Eldorado or the Bank has with its respective directors, officers and certain
other employees (the "Indemnification Agreements"). Such Indemnification
Agreements have been made available to CSBI.

           (e)   This Section 5.11.2, which shall survive consummation of the
Merger at the Effective Time and shall (i) continue in effect for the respective
periods of time set forth herein, (ii) is intended to benefit each present and
former director and officer of Eldorado or the Bank and any other person,
including any employee of Eldorado or the Bank, who is entitled by the express
terms of this Section to any rights hereunder (and each of whom shall be
entitled to enforce the provisions of this Section), and (iii) shall be binding
on all successors and assigns of each of CSBI, the Surviving Corporation,
Eldorado and the Bank. In the event CSBI or any of its successors or assigns (i)
consolidates with or merges into any other Person and shall not be the
continuing or surviving corporation or entity of such consolidation or merger,
or (ii) transfers or conveys all or substantially all of its properties and
assets to any Person, then, and in each such case, to the extent necessary,
proper provision shall be made so that the successors and assigns of CSBI or the
continuing or Surviving Corporation or entity, or the purchaser or transferee of
such properties and assets, as the case may be, assume the obligations set forth
in this section.


     5.12  FINANCING MATTERS.

          5.12.1 Information Regarding Financing. Between the date hereof and
the Effective Time, CSBI shall provide to Eldorado, not later than the last
Business Day of each month, updates describing the status of CSBI's financing
for the Merger (the "Merger Financing"), including reports on its progress in
satisfying any conditions precedent thereto (other than the conditions relating
to, or also constituting conditions precedent to, the consummation of the
Merger), and attaching copies of definitive 


                                      A-32
<PAGE>   124
APPENDIX A


investment documents (or amendments thereto) entered into during the month then
ended. Further, CSBI shall advise Eldorado, promptly after their occurrence, of
any developments, changes, events or circumstances occurring after the date
hereof that will or could reasonably be expected to have a material and adverse
effect on CSBI's ability to satisfy any material conditions to the Merger
Financing or otherwise to consummate the Merger Financing. As of the Closing
Date, CSBI will have received valid and binding subscription agreements for
investments in CSBI payable on or before the Closing Date, that make available
to CSBI adequate funds such that CSBI can deliver (or cause to be delivered) at
the Closing the aggregate amount of the Merger Consideration.

          5.12.2 Additional Financing to be Obtained. In addition to the Merger
Financing that CSBI has represented (under Section 4.11) has been arranged prior
to the date hereof, CSBI shall use its best efforts to obtain, and provide to
Eldorado, by December 31, 1996 one or more commitment letters or subscription
agreements (the "Remaining Financing Commitments") for additional Merger
Financing in an amount not less than $8,600,000. To the extent reasonably
requested by Eldorado's financial advisor, CSBI shall also provide to Eldorado
reasonable information substantiating the financial capacity of the party(ies)
to such Remaining Financing Commitments. At any time on or after January 1,
1996, if CSBI has not provided copies of Remaining Financing Commitments
representing Merger Financing in the amount required by this Section 5.12.2
prior to the giving of such notice, Eldorado may give notice to CSBI that
significant doubt has arisen regarding CSBI's ability to close on the Merger
Financing and demanding written assurances regarding the availability of the
Merger Financing as contemplated by Section 5.12.3. In the event of such a
demand, CSBI shall be obligated to deliver assurances and other documentation in
the manner and by the deadline provided under Section 5.12.3.

          5.12.3 Changes in Financing Status. In the event that, between the
date hereof and the Effective Time, (a) it is determined that any of CSBI's
representations and warranties contained in this Agreement shall not have been
true and correct as of the dates when made and, as a consequence thereof,
Eldorado reasonably determines that there is significant doubt regarding CSBI's
ability to close on any portion of the Merger Financing representing 15% or more
of the aggregate Merger Consideration, or (b) there shall occur any other event
that causes Eldorado reasonably to determine that there is significant doubt
regarding CSBI's ability to close on any portion of the Merger Financing
representing 15% or more of the aggregate Merger Consideration, Eldorado may, by
notice to CSBI, demand written assurances regarding the continued availability
of the Merger Financing. In the event of such a demand, CSBI shall, within
twenty (20) Business Days after Eldorado's notice, deliver to Eldorado either
(x) written confirmation from those financing sources as to which such doubt had
arisen confirming that such sources remain prepared to supply their respective
portions of the Merger Financing together with, if applicable (based on the
nature of the foregoing doubt) information reasonably acceptable to Eldorado's
financial advisor substantiating the financial capacity of such sources to
supply such funds, and/or (y) one or more commitment letters or subscription
agreements for substitute Merger Financing in an aggregate amount not less than
the amount of Merger Financing as to which Eldorado reasonably considers such
doubt not to have been alleviated in all material respects pursuant to clause
(x).

     5.13  ELDORADO ACCRUALS AND RESERVES.

          5.13.1 Classification of Assets and Maintenance of Reserves. Eldorado
agrees that, at all times prior to the Effective Time, Eldorado shall classify
its assets and adjust its loan loss, OREO reserves and tax reserves in a manner
consistent with (a) its policies and practices in effect as of September 30,
1996, and (b) any requirement of a Bank Regulator, including those imposed as a
consequence of an examination 


                                      A-33
<PAGE>   125
APPENDIX A


of Eldorado by such regulator. CSBI may from time to time, in its discretion,
conduct a review of Eldorado's asset classifications and the adequacy of
Eldorado's allowance for loan and lease losses, OREO reserves and tax reserves.
If, in the reasonable judgment of CSBI based the foregoing classification and
reserve standards, any assets should be reclassified or any of such reserves
should be increased, CSBI may propose such reclassification or increase to
Eldorado; provided, however, that any such proposal shall be delivered to
Eldorado on or before the fifth Business Day following the Federal Reserve
Bank's acceptance of CSBI's application filed therewith. If and to the extent
that Eldorado agrees with such proposed reclassification or increase, Eldorado
shall effect the same on its books and records. If and to the extent that
Eldorado refuses to effect one or more proposed reclassifications or increases,
CSBI may, in its discretion, refer such matter for review and determination by
an Impartial Arbiter, the fees and expenses of which shall be borne equally by
the Parties. The Impartial Arbiter's determination shall be made based on
prevailing standards in the commercial banking industry. The Impartial Arbiter
shall not be constrained to adopt the position of either Party with respect to
any matter presented to it and shall be free to classify any asset at any
intermediate classification, and adjust any reserve at any intermediate amount,
in its sole judgment; provided, however, that the Impartial Arbiter shall not
adopt a position on any matter referred to it outside the range bounded by the
positions of the Parties. The determination by the Impartial Arbiter shall be
final and binding on both Parties. Notwithstanding anything to the contrary
contained herein, Eldorado may, in its discretion, defer any reclassification of
an asset or increase in a reserve determined to be appropriate pursuant to this
Section 5.13.1 until immediately prior to (and conditioned upon the occurrence
of) the Closing, but any such reclassification or increase shall be considered
to be effective for purposes of determining Eldorado's satisfaction of the
provisions of Section 6.2.2 as that section applies to Section 3.12. Nothing in
this Section 5.13.1 shall derogate from CSBI's right to obtain information from
and regarding Eldorado throughout the period from the date hereof through the
Effective Time.

          5.13.2 Certain Other Pre-Closing Adjustments.

           (a)   Subject to subsection (c) of this Section 5.13.2, prior to the
Effective Time, Eldorado and CSBI shall review Eldorado's loan, OREO, accrual
and reserve policies and practices (including loan classifications and levels of
tax, loan and OREO reserves and accruals) and, to the extent determined
necessary or advisable by CSBI in its sole discretion, and consistent in all
events with GAAP and the accounting rules, regulations and interpretations of
the SEC, modify and change such policies and practices to (i) reflect CSBI's
plans with respect to the conduct of Eldorado's business following the Merger,
and (ii) make adequate provision for the costs and expenses relating thereto so
as to be applied consistently on a satisfactory basis with those of CSBI.

           (b)   Subject to subsection (c) of this Section 5.13.2, Eldorado
agrees that, prior to the Effective Time, Eldorado shall adjust its loan loss
and OREO reserves as CSBI may determine, consistent with GAAP and the accounting
rules, regulations and interpretations of the SEC but in CSBI's sole discretion,
is appropriate in light of the then-anticipated post-closing grading,
classification or disposition of the relevant Eldorado assets.

           (c)   Eldorado's obligations to implement the changes described in
this Section 5.13.2 are conditioned upon (i) prior written notice from CSBI that
all conditions to CSBI's obligations to consummate the Merger provided herein
(other than deliveries to be made at the Closing) have been satisfied or waived,
(ii) the reasonable determination by Eldorado that all conditions to Eldorado's
obligations to consummate the Merger provided herein (other than deliveries to
be made at the Closing) have been satisfied or waived, (iii) receipt of written
confirmation from CSBI that CSBI has, either directly or in one or more escrow
accounts, 


                                      A-34
<PAGE>   126
APPENDIX A


cash equal to the aggregate Merger Consideration (less any Redemption to be
furnished by Eldorado), and (iv) the absence of any reasonable basis for
Eldorado to expect that the Merger will not be consummated.

           (d)   No accruals or reserves required solely by this Section 5.13.2
shall be considered in determining Eldorado's satisfaction of the provisions of
Section 6.2.1 as that section applies to Section 3.12.

     5.14  STOCK OPTION AGREEMENT.  Eldorado agrees that, as a condition of and
as an inducement to CSBI to enter into this Agreement, Eldorado will enter into
a Stock Option Agreement, in the form attached as Exhibit 5.14 and dated of even
date herewith, immediately upon the execution and delivery of this Agreement.


                                   ARTICLE VI
                              CONDITIONS TO CLOSING

     6.1   CONDITIONS TO OBLIGATIONS OF BOTH PARTIES.  The obligations of CSBI,
Merger Sub and Eldorado to consummate the Merger are subject to the satisfaction
of each of the following conditions:

          6.1.1 Approval by Eldorado's Shareholders. The Merger shall have been
approved by the affirmative vote of the holders of a majority of all shares of
Common Stock entitled to vote thereon.

          6.1.2 Regulatory Approvals. All approvals of any Governmental Entity
required for the consummation of the Merger (including the Eldorado Governmental
Approvals and the CSBI Governmental Approvals but expressly excluding any
approval required for the Bank to dividend funds to Eldorado Bancorp for
purposes of funding the Redemption) shall have been obtained and shall remain in
full force and effect; all statutory or other required waiting periods in
respect thereof shall have expired; and no approval of any Governmental Entity
shall have imposed any condition or requirement which, in the reasonable opinion
of CSBI, would so materially adversely affect the economic or business benefits
of the Merger to CSBI so as to render inadvisable the consummation thereof;
provided, however, that a failure to obtain any required approval of a
Redemption by Eldorado or of a dividend from the Bank to Eldorado Bancorp to
fund a Redemption shall in no event constitute a failure of this condition.

          6.1.3 No Pending or Threatened Claims. There shall be no claim,
action, suit, investigation or other proceeding pending or overtly threatened
before any court or other Governmental Entity that presents a substantial risk
of restraint or prohibition of the Merger or the obtaining of material damages
from Eldorado, CSBI or Merger Sub or their respective officers or directors in
connection therewith; and no such restraint or prohibition shall be effective as
of the Closing, whether or not the action in which the same was entered shall
remain pending.

     6.2   CONDITIONS TO THE OBLIGATIONS OF CSBI AND MERGER SUB. The obligations
of Merger Sub to consummate the Merger, and of CSBI to cause Merger Sub to
consummate the Merger, are further subject to the satisfaction of, or CSBI's
written waiver of, each of the following conditions:

          6.2.1 Accuracy of Representations and Warranties When Made. Eldorado's
representations and warranties contained in this Agreement shall have been true
and correct as of the dates when made (except with respect to events and
conditions waived by CSBI pursuant to Section 5.5), except to the extent that
(without giving effect to any qualifications contained therein relating to
"materiality" or the 


                                      A-35
<PAGE>   127
APPENDIX A


absence of a "Material Adverse Effect") the event or development rendering such
representation or warranty untrue, individually or in the aggregate with all
other events or developments rendering that or any other representation or
warranty untrue, shall not have resulted in or constitute, and could not
reasonably be expected to result in or constitute, a Material Adverse Effect on
Eldorado or on Eldorado's ability to consummate the Merger.

          6.2.2 Bringdown of Representations and Warranties at Closing.
Eldorado's representations and warranties contained in this Agreement shall
remain true and correct as of the Closing as though made at and as of the
Closing (excepting only representations and warranties which speak (other than
in the preamble to Article III) expressly as of an earlier specified date and
except with respect to events and conditions waived by CSBI pursuant to Section
5.5), except to the extent that (without giving effect to any qualifications
contained therein relating to "materiality" or the absence of a "Material
Adverse Effect") the event or development rendering such representation or
warranty untrue, individually or in the aggregate with all other events or
developments rendering that or any other representation or warranty untrue,
shall not have resulted in or constitute, and could not reasonably be expected
to result in or constitute, a Material Adverse Effect on Eldorado or on
Eldorado's ability to consummate the Merger.

          6.2.3 Compliance with Covenants. Eldorado shall have performed,
satisfied and complied with, in all material respects, each of its agreements
and covenants contained in Articles II and V and elsewhere in this Agreement,
unless the failure to perform, satisfy or comply relates to an immaterial
obligation that, taken together with all other such failures, does not
constitute a material failure by Eldorado to perform its obligations hereunder.

          6.2.4 Securities Outstanding. There shall be no shares of Common Stock
or other Eldorado securities issued and outstanding as of the Effective Time
other than (a) the 3,787,734 shares issued and outstanding as of the date
hereof, and (b) any shares issued upon the exercise of Options subsequent to the
date hereof, which exercise has been in accordance with the terms of the
applicable Option as in effect on the date hereof.

application on the basis of matters associated predominantly with Eldorado's
condition, regulatory compliance or similar matters, or (y) an order, decree or
judgment entered in an action brought principally (i) against Eldorado, (ii)

terminate this Agreement:

          7.3.1 if Eldorado has breached any representation or warranty
contained in this Agreement and such breach is of a nature that would, in the
reasonable determination of CSBI, cause the failure of the condition set forth
in Section 6.2.1, or if Eldorado has failed to perform, satisfy or comply with
any of its agreements and covenants contained in this Agreement (other than as
described in Section 7.3.2) and such failure is of a nature that would, in the

such breach or failure has not been cured prior to the expiration of such
period;

of its representations, warranties, covenants or agreements contained in this
Agreement or (b) all affirmative approvals of Governmental Entities that are
necessary to the consummation of the Merger have been obtained and the Parties
are in the so-called "waiting period" relating to Department of Justice review,
provided, that (x) if the basis for such termination is the failure of the
Shareholders to approve the Merger, Eldorado shall reimburse CSBI for CSBI's
reasonable and documented Expenses, not to exceed $400,000, and (y) if the basis
for such termination is the failure to obtain those approvals of Governmental
Entities required under Section 6.1.2, a condition to the effectiveness of such

shares of Common Stock with respect to which CSBI holds proxies or powers of
attorney against the approval of the Merger; and provided further that Eldorado

Section) within ten (10) Business Days after Eldorado's receipt of the invoice

shall be barred from recovering damages for any breach of any term of this
Agreement or from seeking any other remedy at law or in equity from Eldorado,
the Bank or any of the Indemnified Parties (other than with respect to such

           (c)  If this Agreement is terminated under provisions that entitle
Eldorado to receive and retain the Deposit, and the Deposit is so disbursed to
Eldorado in accordance with the Deposit Escrow Agreement without challenge to
such disbursement by CSBI, then Eldorado's receipt and acceptance of the Deposit

              THE TRANSFER OF THIS AGREEMENT IS SUBJECT TO CERTAIN PROVISIONS
              CONTAINED HEREIN AND TO THE RESALE RESTRICTIONS UNDER THE
              SECURITIES ACT OF 1933, AS AMENDED


              THIS OPTION GRANTED UNDER THIS AGREEMENT WILL AUTOMATICALLY
              EXPIRE ON THE DATE DETERMINED IN ACCORDANCE WITH SECTIONS 2 AND
              14 HEREOF, AND CONTAINS A LIMITATION ON THE AMOUNT WHICH A HOLDER
              MAY REALIZE ON A SALE, TRANSFER OR OTHER DISPOSITION OF THE
              OPTION GRANTED HEREUNDER OR, IN CERTAIN EVENTS, OF THE SHARES
              WHICH MAY BE ACQUIRED ON EXERCISE THEREOF (THE "OPTION SHARES"),
              PURSUANT TO SECTION 14 OF THIS AGREEMENT. THE TRANSFERABILITY OF
              THE OPTION AND THE OPTION SHARES IS ALSO RESTRICTED PURSUANT TO
              SECTION 12 HEREOF.


     STOCK OPTION AGREEMENT, dated December 24, 1996, between COMMERCE SECURITY
BANCORP, INC., a Delaware corporation ("Grantee"), and ELDORADO BANCORP, a
California corporation ("Issuer").

                                    RECITALS

     WHEREAS, Grantee and Issuer have entered into an Agreement and Plan of
Merger immediately prior to the execution and delivery hereof (the "Merger
Agreement"); and

     WHEREAS, as a condition and inducement to Grantee's pursuit of the
transactions contemplated by the Merger Agreement and in consideration therefor,
Issuer has agreed to grant Grantee the Option (as hereinafter defined):

                                    AGREEMENT

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements set forth herein and in the Merger Agreement, the parties hereto
agree as follows:

     1.  a) Issuer hereby grants to Grantee an unconditional, irrevocable option
(the "Option") to purchase, subject to the terms hereof, up to 468,200 fully
paid and nonassessable shares of the common stock, no par value, of Issuer
("Common Stock") at a price of $22.00 per share; provided, however, that in the
event Issuer issues or agrees to issue any shares of Common Stock at a price
less than $22.00 per share (as adjusted pursuant to subsection (b) of Section 5)
other than as permitted by 


                                      B-1
<PAGE>   139
APPENDIX B


the Merger Agreement, such price shall be equal to such lesser price (such
price, as adjusted if applicable, the "Option Price"); provided further that in
no event shall the number of shares for which this Option is exercisable exceed
11.0% of the Issuer's issued and outstanding shares of Common Stock, calculated
on a pro forma basis taking into account the shares issued upon the exercise of
this Option. The number of shares of Common Stock that may be received upon the
exercise of the Option and the Option Price are subject to adjustment as herein
set forth. Capitalized terms used in this Agreement and not defined herein shall
have the meanings assigned thereto in the Merger Agreement.

     (b) In the event that any additional shares of Common Stock are issued or
otherwise become outstanding after the date of this Agreement (other than
pursuant to or permitted by this Agreement and other than pursuant to an event
described in Section 5(a) hereof), the number of shares of Common Stock subject
to the Option shall be increased so that, after such issuance, such number
together with any shares of Common Stock previously issued pursuant hereto,
equals 11.0% of the number of shares of Common Stock issued and outstanding,
calculated on a pro forma basis taking into account the shares issued upon the
exercise of this Option. Nothing contained in this Section 1(b) or elsewhere in
this Agreement shall be deemed to authorize Issuer or Grantee to breach any
provision of the Merger Agreement.

     2.  (a) The Holder (as hereinafter defined) may exercise the Option, in
whole or part, if, but only if, prior to the Exercise Termination Event (as
hereinafter defined), the Grantee has become entitled to receive payment of the
Termination Fee pursuant to the terms of the Merger Agreement prior to the
termination of the Merger Agreement (the "Triggering Event") and whether or not
such Termination Fee has in fact been paid to the Grantee. The term "Holder"
shall mean the holder or holders of the Option. The term "Exercise Termination
Event" shall mean termination of the Merger Agreement in accordance with the
provisions thereof.

         (b) If the Option has become exercisable by Grantee pursuant to Section
2(a), the Option shall continue in full force and effect until the earlier of:
(1) the date as of which it has been exercised in full by Grantee in accordance
with Section 2(c) hereof, or (ii) twelve (12) months following the termination
of the Merger Agreement or such earlier date as is determined in accordance with
Section 14(d) (the "Option Termination Date").

         (c) In the event the Holder is entitled to and wishes to exercise the
Option, it shall send to Issuer a written notice (the date of which being herein
referred to as the "Notice Date") specifying (i) the total number of shares it
will purchase pursuant to such exercise and (ii) a place and date not earlier
than three Business Days nor later than 20 Business Days after the Notice Date
for the closing of such purchase (the "Closing Date"); provided that if prior
notification to or approval of the Federal Reserve Board or any other Bank
Regulator is required in connection with such purchase, the Holder shall
promptly (but in no event later than five (5) Business Days after the Notice
Date) file the required notice or application for approval, shall promptly
notify the Issuer of such filing, and shall expeditiously process the same and
the period of time that otherwise would run pursuant to this sentence shall run
instead from the date on which any required notification periods have expired or
been terminated or such approvals have been obtained and any requisite waiting
period or periods shall have passed. Any exercise of the Option shall be deemed
to occur on the Notice Date relating thereto.

APPENDIX B


         (d) At the closing referred to in subsection (c) of this Section 2, the
Holder shall (i) pay to Issuer the aggregate purchase price for the shares of
Common Stock purchased pursuant to the exercise of the Option in immediately
available funds by wire transfer to a bank account designated by Issuer,
provided that failure or refusal of Issuer to designate such a bank account
shall not preclude the Holder from exercising the Option and (ii) present and
surrender this Agreement to the Issuer at its principal executive offices.

         (e) At such closing, simultaneously with the delivery of immediately
available funds as provided in subsection (d) of this Section 2, Issuer shall
deliver to the Holder a certificate or certificates representing the number of
shares of Common Stock purchased and paid for by the Holder and, if the Option
should be exercised in part only, a new Option evidencing the rights of the
Holder thereof to purchase the balance of the shares purchasable hereunder.

         (f) Certificates for Common Stock delivered at a closing hereunder may
be endorsed with a restrictive legend that shall read substantially as follows:

     "THE TRANSFER OF THE SHARES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO
     CERTAIN PROVISIONS OF AN AGREEMENT BETWEEN THE REGISTERED HOLDER HEREOF AND
     ISSUER AND TO RESALE RESTRICTIONS ARISING UNDER THE SECURITIES ACT OF 1933,
     AS AMENDED. A COPY OF SUCH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICE OF
     ISSUER AND WILL BE PROVIDED TO THE HOLDER HEREOF WITHOUT CHARGE UPON
     RECEIPT BY ISSUER OF A WRITTEN REQUEST THEREFOR."

It is understood and agreed that: (i) the reference to the resale restrictions
of the Securities Act of 1933 (the "1933 Act") in the above legend shall be
removed by delivery of substitute certificate(s) without such reference if the
Holder shall have delivered to Issuer a copy of a letter from the staff of the
SEC, or an opinion of counsel, in form and substance reasonably satisfactory to
Issuer, to the effect that such legend is not required for purposes of the 1933
Act; (ii) the reference to the provisions of this Agreement in the above legend
shall be removed by delivery of substitute certificate(s) without such reference
if the shares have been sold or transferred in compliance with the provisions of
this Agreement and under circumstances that do not require the retention of such
reference and the Holder shall have delivered to Issuer an opinion of counsel,
in form and substance reasonably satisfactory to Issuer, that the retention of
such reference on the substitute certificate(s) is not required for purposes of
the 1933 Act; and (iii) the legend shall be removed in its entirety if the
conditions in the preceding clauses (i) and (ii) are both satisfied. In
addition, such certificates shall bear any other legend as may be required by
Law.

         (g) Upon the giving by the Holder to Issuer of the written notice of
exercise of the Option provided for under subsection (c) of this Section 2 and
the tender of the applicable purchase price in immediately available funds, the
Holder shall be deemed to be the holder of record of the shares of Common Stock
issuable upon such exercise, notwithstanding that the stock transfer books of
Issuer shall then be closed or that certificates representing such shares of
Common Stock shall not then be actually delivered to the Holder. Issuer shall
pay all expenses, and any and all Taxes and other charges that may be payable in
connection with the preparation, issue and delivery of stock certificates under
this Section 2 in the name of the Holder except that Holder shall pay all
transfer and similar taxes if Holder requests the issuance of the stock
certificate in a name other than its own.

APPENDIX B


     3. Issuer agrees: (i) that it shall at all times during the term of the
Option maintain, free from preemptive rights, sufficient authorized but unissued
or treasury shares of Common Stock so that the Option may be exercised without
additional authorization of Common Stock after giving effect to all other
options, warrants, convertible securities and other rights to purchase Common
Stock; (ii) that it will not, by charter amendment or through reorganization,
consolidation, merger, dissolution or sale of assets, or by any other voluntary
act, avoid or seek to avoid the observance or performance of any of the
covenants, stipulations or conditions to be observed or performed hereunder by
Issuer; (iii) promptly to take, at the sole expense of Holder all action as may
from time to time be reasonably required (including (x) complying with all
pre-merger notification, reporting and waiting period requirements specified in
15 U.S.C. Sec. 18a and regulations promulgated thereunder and (y) in the event,
under the Bank Holding Company Act of 1956, as amended, or any state or other
federal banking Law, prior approval of or notice to the Federal Reserve Board or
to any other Governmental Entity is necessary before the Option may be
exercised, cooperating fully with the Holder, at its sole expense, in preparing
such applications or notices and providing such information to the Federal
Reserve Board or such other Governmental Entity as they may require) in order to
permit the Holder to exercise the Option and Issuer duly and effectively to
issue shares of Common Stock pursuant hereto; and (iv) promptly to take all
action provided herein to protect the rights of the Holder against dilution.

     4. This Agreement (and the Option granted hereby) are exchangeable, without
expense, at the option of the Holder, upon presentation and surrender of this
Agreement at the principal office of the Issuer, for other Agreements providing
for Options of different denominations entitling the holder thereof to purchase,
on the same terms and subject to the same conditions as are set forth herein, in
the aggregate the same number of shares of Common Stock purchasable hereunder.
The terms "Agreement" and "Option" as used herein include any Agreements and
related Options and, where applicable, Substitute Options for which this
Agreement (and the Option granted hereby) may be exchanged. Upon receipt by
Issuer of evidence reasonably satisfactory to it of the loss, theft, destruction
or mutilation of this Agreement, and (in the case of loss, theft or destruction)
of reasonably satisfactory indemnification, and upon surrender and cancellation
of this Agreement, if mutilated, Issuer will execute and deliver a new Agreement
of like tenor and date. Any such new Agreement executed and delivered shall
constitute an additional contractual obligation on the part of Issuer, whether
or not the Agreement so lost, stolen, destroyed or mutilated shall at any time
be enforceable by anyone, provided that Holder indemnifies the Issuer from any
and all liabilities, losses, costs and expenses, including, but not limited to
reasonably attorneys fees as and when incurred by Issuer, arising out of any
claim by anyone that it is entitled to enforce against Issuer the Agreement that
was lost, stolen, destroyed or mutilated.

     5. In addition to the adjustment in the number of shares of Common Stock
that are purchasable upon exercise of the Option pursuant to Section 1 of this
Agreement, the number of shares of Common Stock purchasable upon the exercise of
the Option shall be subject to adjustment from time to time as provided in this
Section 5. In the event of any change in Common Stock by reason of (x) stock
dividends, split-ups, mergers, recapitalizations, combinations, subdivisions,
conversions, exchanges of shares or the like, or (y) distributions on or in
respect of the Common Stock prior to any Exercise Termination Event that would
be prohibited under the terms of the Merger Agreement, the


                                      B-4
<PAGE>   142
APPENDIX B


type and number of shares of Common Stock then purchasable upon exercise hereof
and the Option Price shall be appropriately adjusted in such manner as shall
fully preserve the economic benefits provided hereunder and proper provision
shall be made in any agreement governing any such transaction to provide for
such proper adjustment and the full satisfaction of the Issuer's obligations
hereunder.

     6.  [Reserved]

     7.  (a) At any time after the occurrence of a Repurchase Event (as defined
below) (i) at the request of the Holder, delivered prior to the Option
Termination Date (or such later period as provided in Section 10), Issuer shall
repurchase the Option from the Holder at a price (the "Option Repurchase Price")
equal to (x) the amount by which (A) the market/offer price (as defined below)
exceeds (B) the Option Price, multiplied by the number of shares for which this
Option may then be exercised and (ii) at the request of the owner of Option
Shares from time to time (the "Owner"), delivered prior to the Option
Termination Date (or such later period as provided in Section 10), Issuer shall
repurchase such number of the Option Shares from the Owner as the Owner shall
designate at a price (the "Option Share Repurchase Price") equal to (x) the
market/offer price multiplied by (y) the number of Option Shares so designated.
The term "market/offer price" shall mean the highest of (i) the price per share
of Common Stock at which a tender or exchange offer therefor has been made, (ii)
the price per share of Common Stock to be paid by any third party pursuant to an
agreement with Issuer, (iii) the highest closing price for shares of Common
Stock within the six-month period immediately preceding the date the Holder
gives notice of the required repurchase of this Option or the Owner gives notice
of the required repurchase of Option Shares, as the case may be, or (iv) in the
event of a sale of all or substantially all of Issuer's assets or deposits, the
sum of the net price paid in such sale for such assets or deposits and the
current market value of the remaining net assets of Issuer as determined by a
nationally recognized investment banking firm selected by the Holder or the
Owner, as the case may be, and reasonably acceptable to Issuer, divided by the
number of shares of Common Stock of Issuer outstanding at the time of such sale.
In determining the market/offer price, the value of consideration other than
cash shall be determined by a nationally recognized investment banking firm
selected by the Holder or Owner, as the case may be, and reasonably acceptable
to Issuer.

     (b) The Holder and the Owner, as the case may be, may exercise its right to
require Issuer to repurchase the Option and any Option Shares pursuant to this
Section 7 by surrendering for such purpose to Issuer, at its principal office, a
copy of this Agreement or certificates for Option Shares, as applicable,
accompanied by a written notice or notices stating that the Holder or the Owner,
as the case may be, elects to require Issuer to repurchase this Option and/or
the Option Shares in accordance with the provisions of this Section 7. As
promptly as practicable, and in any event within five Business Days after the
surrender of the Option and/or certificates representing Option Shares and the
receipt of such notice or notices relating thereto, Issuer shall deliver or
cause to be delivered to the Holder the Option Repurchase Price and/or to the
Owner the Option Share Repurchase Price therefor or the portion thereof that
Issuer is not then prohibited under applicable Law from so delivering.

     (c) To the extent that Issuer is prohibited under applicable Law, from
repurchasing the Option and/or the Option Shares in full, Issuer shall
immediately so notify the Holder and/or the Owner and thereafter deliver or
cause to be delivered, from time to time, to the Holder and/or the Owner, as


                                      B-5
<PAGE>   143
APPENDIX B


appropriate, the portion of the Option Repurchase Price and the Option Share
Repurchase Price, respectively, that it is no longer prohibited from delivering,
within five Business Days after the date on which Issuer is no longer so
prohibited; provided, however, that if Issuer at any time after delivery of a
notice of repurchase pursuant to paragraph (b) of this Section 7 is prohibited
under applicable Law, from delivering to the Holder and/or the Owner, as
appropriate, the Option Repurchase Price and the Option Share Repurchase Price,
respectively, in full (and Issuer hereby undertakes to use its reasonable best
efforts to obtain all required regulatory and legal approvals and to file any
required notices as promptly as practicable in order to accomplish such
repurchase), the Holder or Owner may revoke its notice of repurchase of the
Option or the Option Shares whether in whole or to the extent of the
prohibition, whereupon, in the latter case, Issuer shall promptly (i) deliver to
the Holder and/or the Owner, as appropriate, that portion of the Option Purchase
Price or the Option Share Repurchase Price that Issuer is not prohibited from
delivering; and (ii) deliver, as appropriate, either (A) to the Holder, a new
Agreement evidencing the right of the Holder to purchase that number of shares
of Common Stock obtained by multiplying the number of shares of Common Stock for
which the surrendered Agreement was exercisable at the time of delivery of the
notice of repurchase by a fraction, the numerator of which is the Option
Repurchase Price less the portion thereof theretofore delivered to the Holder
and the denominator of which is the Option Repurchase Price, or (B) to the
Owner, a certificate for the Option Shares it is then so prohibited from
repurchasing. If an Exercise Termination Event shall have occurred prior to the
date of the notice by Issuer described in the first sentence of this subsection
(c), or shall be scheduled to occur at any time before the expiration of a
period ending on the thirtieth day after such date, the Holder shall nonetheless
have the right to exercise the Option until the expiration of such 30-day
period.

     (d) For purposes of this Section 7, a Repurchase Event shall be deemed to
have occurred upon the occurrence of any of the following events or transactions
after the date hereof:

          (i)  the acquisition by any Person (other than Grantee or any of its
     Subsidiaries (each a "Grantee Subsidiary") of beneficial ownership of 50%
     or more of the then-outstanding Common Stock; or

          (ii) the consummation of any Strategic Transaction (as hereinafter
     defined).

For purposes of this Agreement, (a) "Strategic Transaction" shall mean (i) any
purchase or other acquisition of 50% or more of the assets, assumption of 50% or
more of the liabilities, or purchase or other acquisition of 50% or more of the
equity (on a pro forma basis) of Issuer (including any subsidiary of the Issuer
(each an "Issuer Subsidiary")), (ii) any merger or other business combination
involving Issuer or any Issuer Subsidiary, (iii) any recapitalization involving
Issuer or any Issuer Subsidiary resulting in an extraordinary dividend or
distribution to Issuer or the Shareholders, or (iv) any self-tender for or
redemption of 50% or more of the Common Stock, (b) "Subsidiary" shall mean a
"significant subsidiary" of Issuer within the meaning set forth in Rule 1-02 of
Regulation S-X promulgated by the SEC, and (c) "Person" shall have the meaning
set forth in Sections 3(a)(9) and 13(d)(3) of the Securities Exchange Act of
1934 (the "1934 Act") and the rules and regulations promulgated by the SEC
thereunder.

     8.  (a) In the event that prior to an Exercise Termination Event, Issuer
shall enter into an 


                                      B-6
<PAGE>   144
APPENDIX B


agreement (i) to consolidate with or merge into any Person, other than Grantee
or a Grantee Subsidiary, and shall not be the continuing or surviving
corporation of such consolidation or merger, (ii) to permit any Person, other
than Grantee or a Grantee Subsidiary, to merge into Issuer and Issuer shall be
the continuing or surviving corporation, but, in connection with such merger,
the then-outstanding shares of Common Stock (x) shall be changed into or
exchanged for stock or other securities of any other Person or cash or any other
property or (y) after such merger shall represent less than 33% of the
outstanding shares and share equivalents of the merged company, or (iii) to sell
or otherwise transfer all or substantially all of its or any Issuer Subsidiary's
assets or deposits to any Person, other than Grantee or a Grantee Subsidiary,
then, and in each such case, as a part of or in connection with such agreement
provision shall be made so that the Option shall, upon the consummation of such
transaction and upon the terms and conditions set forth herein, be converted
into, and exchanged for, an Option (the "Substitute Option") whereunder the
Holder shall be entitled to receive, upon exercise thereof (but only to the
extent so exercised), the number of shares of stock or other securities
("Substitute Securities") or property of the Acquiring Corporation, to which a
holder of Common Stock (or other securities then deliverable upon the exercise
of this Option) would have been entitled upon the consummation of such
transaction. If property is deliverable upon exercise of the Substitute Option
and such property consists, in whole or in part, of cash in excess of the Option
Price, the Holder may, at the Holder's election, exercise the Substitute Option
without making payment of the Option Price and, in such case, the Issuer or the
Acquiring Corporation shall, upon distribution to the Holder, consider the
Option Price to have been paid in full and, in making settlement to the Holder,
shall deduct an amount equal to the Option Price from the amount payable to the
Holder.

     (b) "Acquiring Corporation" shall mean (i) the continuing or surviving
corporation of a consolidation or merger with Issuer (if other than Issuer),
(ii) Issuer, in a merger in which Issuer is the continuing or surviving Person,
and (iii) the transferee of all or substantially all of Issuer's assets or
deposits (or the assets or deposits of an Issuer Subsidiary).

     (c) The Substitute Option shall have the same terms as the Option,
provided, that if the terms of the Substitute Option cannot, for legal reasons,
be the same as the Option, such terms shall be as similar as possible and in no
event less advantageous to the Holder. The issuer of the Substitute Option shall
also enter into an agreement with the then Holder or Holders of the Substitute
Option in substantially the same form as this Agreement (after giving effect for
such purpose to the provisions of Section 9), which agreement shall be
applicable to the Substitute Option. The exercise price of the Substitute Option
per share of Substitute Securities shall then be equal to the Option Price
multiplied by a fraction, the numerator of which shall be the number of shares
of Common Stock for which the Option is then exercisable and the denominator of
which shall be the number of shares of Substitute Securities for which the
Substitute Option is exercisable.

     (d) Issuer shall not enter into any transaction described in subsection (a)
of this Section 8 unless the Acquiring Corporation and any Person that controls
the Acquiring Corporation assume in writing all the obligations of Issuer
hereunder.

     9.  (a) At the request of the holder of the Substitute Option (the
"Substitute Option Holder") given prior to the Option Termination Date, the
issuer of the Substitute Option (the "Substitute Option Issuer") shall
repurchase the Substitute Option from the Substitute Option Holder at a price
(the 


                                      B-7
<PAGE>   145
APPENDIX B


"Substitute Option Repurchase Price") equal to (x) the amount by which (i) the
Highest Closing Price (as hereinafter defined) exceeds (ii) the exercise price
of the Substitute Option, multiplied by the number of shares of Substitute
Securities for which the Substitute Option may then be exercised plus (y) the
Holder's out-of-pocket expenses (to the extent not previously reimbursed), and
at the request of the owner (the "Substitute Share Owner") of shares of
Substitute Securities (the "Substitute Shares") given prior to the Option
Termination Date, the Substitute Option Issuer shall repurchase the Substitute
Shares at a price (the "Substitute Share Repurchase Price") equal to (x) the
Highest Closing Price multiplied by the number of Substitute Shares so
designated plus (y) the Holder's out-of-pocket expenses (to the extent not
previously reimbursed). The term "Highest Closing Price" shall mean the highest
closing price for shares of Substitute Securities within the six-month period
immediately preceding the date the Substitute Option Holder gives notice of the
required repurchase of the Substitute Option or the Substitute Share Owner gives
notice of the required repurchase of the Substitute Shares, as applicable.

     (b) The Substitute Option Holder and the Substitute Share Owner, as the
case may be, may exercise its respective right to require the Substitute Option
Issuer to repurchase the Substitute Option and the Substitute Shares pursuant to
this Section 9 by surrendering for such purpose to the Substitute Option Issuer,
at its principal office, the agreement for such Substitute Option (or, in the
absence of such an agreement, a copy of this Agreement) and certificates for
Substitute Shares accompanied by a written notice or notices stating that the
Substitute Option Holder or the Substitute Share Owner, as the case may be,
elects to require the Substitute Option Issuer to repurchase the Substitute
Option and/or the Substitute Shares in accordance with the provisions of this
Section 9. As promptly as practicable and in any event within five business days
after the surrender of the Substitute Option and/or certificates representing
Substitute Shares and the receipt of such notice or notices relating thereto,
the Substitute Option Issuer shall deliver or cause to be delivered to the
Substitute Option Holder the Substitute Option Repurchase Price and/or to the
Substitute Share Owner the Substitute Share Repurchase Price therefor or the
portion thereof which the Substitute Option Issuer is not then prohibited under
applicable Law from so delivering.

     (c) To the extent that the Substitute Option Issuer is prohibited under
applicable Law, from repurchasing the Substitute Option and/or the Substitute
Shares in part or in full, the Substitute Option Issuer shall immediately so
notify the Substitute Option Holder and/or the Substitute Share Owner and
thereafter deliver or cause to be delivered, from time to time, to the
Substitute Option Holder and/or the Substitute Share Owner, as appropriate, the
portion of the Substitute Share Repurchase Price, respectively, which it is no
longer prohibited from delivering, within five Business Days after the date on
which the Substitute Option Issuer is no longer so prohibited; provided,
however, that if the Substitute Option Issuer is at any time after delivery of a
notice of repurchase pursuant to subsection (b) of this Section 9 prohibited
under applicable Law, from delivering to the Substitute Option Holder and/or the
Substitute Share Owner, as appropriate, the Substitute 


                                      B-8
<PAGE>   146
APPENDIX B


Option Repurchase Price and the Substitute Share Repurchase Price, respectively,
in full (and the Substitute Option Issuer shall use its best efforts to receive
all required regulatory and legal approvals as promptly as practicable in order
to accomplish such repurchase), the Substitute Option Holder or Substitute Share
Owner may revoke its notice of repurchase of the Substitute Option or the
Substitute Shares either in whole or to the extent of prohibition, whereupon, in
the latter case, the Substitute Option Issuer shall promptly (i) deliver to the
Substitute Option Holder or Substitute Share Owner, as appropriate, that portion
of the Substitute Option Repurchase Price or the Substitute Share Repurchase
Price that the Substitute Option Issuer is not prohibited from delivering; and
(ii) deliver, as appropriate, either (A) to the Substitute Option Holder, a new
Substitute Option evidencing the right of the Substitute Option Holder to
purchase that number of shares of the Substitute Securities obtained by
multiplying the number of shares of the Substitute Securities for which the
surrendered Substitute Option was exercisable at the time of delivery of the
notice of repurchase by a fraction, the numerator of which is the Substitute
Option Repurchase Price less the portion thereof theretofore delivered to the
Substitute Option Holder and the denominator of which is the Substitute Option
Repurchase Price, or (B) to the Substitute Share Owner, a certificate for the
Substitute Option Shares it is then so prohibited from repurchasing. If an
Exercise Termination Event shall have occurred prior to the date of the notice
by the Substitute Option Issuer described in the first sentence of this
subsection (c), or shall be scheduled to occur at any time before the expiration
of a period ending on the thirtieth calendar day after such date, the Substitute
Option Holder shall nevertheless have the right to exercise the Substitute
Option until the expiration of such 30-day period.

     10. The 30-day, 6-month or 12-month periods for exercise of certain rights
under Sections 2, 6, 7, 9 and 12 shall be extended: (i) to the extent necessary
to obtain all regulatory approvals for the exercise of such rights (for so long
as the Holder is using commercially reasonable efforts to obtain such regulatory
approvals), and for the expiration of all statutory waiting periods; and (ii) to
the extent necessary to avoid liability under Section 16(b) of the 1934 Act by
reason of such exercise.

     11. Issuer hereby represents and warrants to Grantee as follows:

     (a) Issuer has full corporate power and authority to execute and deliver
this Agreement and to consummate the transactions contemplated hereby. The
execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly and validly authorized by the
Board of Directors of Issuer and no other corporate proceedings on the part of
Issuer are necessary under its Articles of Incorporation and Bylaws and under
the Laws of the State of California to authorize this Agreement or to consummate
the transactions so contemplated. This Agreement has been duly and validly
executed and delivered by Issuer.

     (b) Issuer has taken all necessary corporate action to authorize and
reserve and to permit it to issue, and at all times from the date hereof through
the termination of this Agreement in accordance with its terms will have
reserved for issuance upon the exercise of the Option, that number of shares of
Common Stock equal to the maximum number of shares of Common Stock at any time
and from time to time issuable hereunder, and all such shares, upon issuance
pursuant thereto, will be duly authorized, validly issued, fully-paid,
nonassessable, and will be delivered free and clear of all claims, liens,
encumbrance and security interests and not subject to any preemptive rights.

     12. Neither of the parties hereto may assign any of its rights or
obligations under this Agreement or the Option created hereunder to any other
Person, without the express written consent of the other party, except that in
the event a Triggering Event shall have occurred prior to an Exercise
Termination Event, Grantee, subject to the express provisions hereof, may assign
in whole or in part its rights and obligations hereunder within 12 months
following such Triggering Event (or such later period as provided in Section 10)
to a person or persons not affiliated with Grantee; provided, 


                                      B-9
<PAGE>   147
APPENDIX B


however, that until the date 30 calendar days following the date on which the
Federal Reserve Board has approved applications by Grantee to acquire the shares
of Common Stock subject to the Option, Grantee may not assign its rights under
the Option except in (i) a widely dispersed public distribution, (ii) a private
placement in which no one party acquires the right to purchase in excess of 2%
of the voting shares of Issuer, (iii) an assignment to a single party (e.g., a
broker or investment banker) for the purpose of conducting a widely dispersed
public distribution on Grantee's behalf, or (iv) any other manner approved by
the Federal Reserve Board. Each Holder of this Option agrees and covenants to
Issuer that it will comply with all applicable federal and state securities laws
in effecting any assignment of this Option, and agrees to indemnify and hold
harmless Issuer and Issuer's officers and directors against any liability
arising thereunder in connection with any such assignment.

     13. Each of Grantee and Issuer will use its best efforts to make all
filings with, and to obtain consents of, all third parties and governmental
authorities necessary to the consummation of the transactions contemplated by
this Agreement, including without limitation applying to the Federal Reserve
Board under the Bank Holding Company Act of 1954 for approval to acquire the
shares issuable hereunder, but Grantee shall not be obligated to apply to state
banking authorities for approval to acquire the shares of Common Stock issuable
hereunder until such time, if ever, as it deems appropriate to do so. After the
Option becomes exercisable, all expenses reasonably incurred by Issuer pursuant
hereto shall be reimbursed to Issuer on its demand by Holder.

     14. (a) Notwithstanding any other provision in this Agreement to the
contrary, the aggregate sum of the Total Profit (as defined below) from each
sale, transfer or other disposition that is made on or before the Option
Termination Date, whether made pursuant to Section 7 or Section 9 hereof or
otherwise (a "Disposition Transaction"), of any Option Securities (as
hereinafter defined) by any Transferring Person (as hereinafter defined) shall
not exceed, in any event. the amount by which One Million Dollars ($1,000,000)
exceeds all out-of pocket expenses or costs incurred by the Issuer or any
Substitute Option Issuer in performing its respective covenants or duties under
this Agreement (the "Issuer Expenses"). (Such excess amount shall be referred to
herein as "Aggregate Profit Ceiling.") For purposes of this Section 14:

          (i)   The Term "Option Securities' means the Option or any portion
     thereof, any Option Shares, any Substitute Option or any portion thereof,
     and any shares or other securities receivable on exercise of any Substitute
     Option ("Substitute Securities");

          (ii)  The term "Transferring Person" shall mean the Grantee or any
     Holder or any Owner of any or all of the Option Securities that engages in
     a Disposition Transaction; and

          (iii) The term "Total Profit" when used with respect to any
     Disposition Transaction shall mean the amount (before taxes and any
     commissions, fees or other expenses incurred by the Transferring Person as
     a result of or in connection with such Disposition Transaction) of the
     difference between (i) the gross amount paid to the Transferring Person for
     the Option Securities sold, transferred or otherwise disposed of in such
     Disposition Transaction (the "Gross Sales Price"), and (ii) the gross
     purchase price paid, if any, for such Option Securities when they were
     acquired by such Transferring Person (the Transferring Person's "Basis",
     which shall not necessarily be the same as its basis for tax purposes);
     provided, however, that (A) if the 


                                      B-10
<PAGE>   148
APPENDIX B


     Disposition Transaction is a disposition of the Option or a Substitute
     Option made by the Grantee or any affiliate thereof, the Transferring
     Person's Basis for purposes hereof shall be deemed to be zero; (B) if the
     Disposition Transaction is a gift or other transaction without the payment
     of consideration to the Transferring Person, then there shall be deemed to
     have been no Total Profit from such Disposition Transaction and the
     purchaser or transferee's Basis shall be deemed to be the Transferring
     Person's Basis; (C) if, in any Disposition Transaction, the Gross Sales
     Price consists, or the consideration paid by Transferring Person on its
     acquisition of the Option Securities being transferred in the Disposition
     Transaction (the "Transferred Option Securities") consists, in whole or in
     part, of securities or other property other than cash, then, for purposes
     of determining the Total Profit for such Disposition Transaction, any
     non-cash consideration included in the Gross Sales Price shall be valued at
     its fair market value on the date of the Disposition Transaction and any
     non-cash consideration paid on the acquisition of such Option Securities by
     the Transferring Person shall be valued at its fair market value on the
     duty of such acquisition, in either instance, by a nationally recognized
     investment banking or property valuation firm, as appropriate for the type
     of property involved; and (D) if the Grantee or any other Holder of the
     Option or any portion thereof receives a Substitute Option pursuant to
     Section 8 hereof and such Substitute Option represents a right to receive
     cash or other property other than shares or other securities of the
     Substitute Option Issuer, then the exercise of such Substitute Option shall
     be deemed to be a Disposition Transaction to the extent of the cash or
     other non-securities property received on exercise thereof, and the cash
     and fair market value of any non-cash assets (other than Substitute
     Securities) shall be the Gross Sales Price in such Disposition Transaction
     and, for purposes thereof, the Transferring Person's Basis shall be a
     pro-rata portion of the Transferring Person's Basis in the Option that was
     exchanged for the Substitute Option allocable to the cash and non-cash
     property (other than the Substitute Securities) receivable on exercise of
     the Substitute Option.

         (c) For purposes of determining if and the date as of which the
Aggregate Profit Ceiling has been reached, on consummation of any Disposition
Transaction the Total Profit arising therefrom shall be added to the sum of
Total Profit (including losses, to the extent realized in a Disposition
Transaction entered into with a person unaffiliated with the Transferring
Person) that has been realized from all other Disposition Transactions of any of
the Option Securities consummated by any Transferring Person prior to or
concurrently therewith. In order to enable determinations to be made of the
Total Profit in each Disposition Transaction and if and the date as of which the
Aggregate Profit Ceiling has been reached or exceeded, each Transferring Person
shall be obligated to provide a written notice of the consummation of any
Disposition Transaction (a "Transfer Notice"), within five (5) business days
thereafter, to the Issuer (or the Substitute Issuer in the case of a Disposition
Transaction involving a Substitute Option or Substitute Securities). Each
Transfer Notice shall (i) describe the nature of the Disposition Transaction,
(ii) the nature and amount of the Gross Sales Price paid for, and the
Transferring person's Basis in, the Transferred Option Securities (and the fair
market value of any non-cash consideration received as part of the Gross Sales
Price or that accounted for the Transferring Person's Basis, as the case may be,
and the manner in which such fair market value was determined), and (iii) the
identity of the purchaser or transferee. Such Transfer Notice also shall contain
a certification of the Chief Financial Officer of the Transferring Person that
the information contained therein is accurate and complete.

APPENDIX B


         (d) In the event that the Aggregate Profit Ceiling is reached on a date
earlier than the expiration of twelve (12) months following the termination of
the Merger Agreement, the Option Termination Date shall be accelerated to, and
shall be deemed to be, such earlier date. On the Option Termination Date
(including as so accelerated):

          (i)  Without any action required on the part of the Issuer or any
     Substitute Issuer or on the part of the Grantee or any other Holder of such
     unexercised portion of the Option or any Substitute Option or on the part
     of any Owner of any Option Shares or Substitute Securities then
     outstanding, any portion of the Option or any Substitute Option which is
     then outstanding and unexercised shall automatically expire and cease to be
     exercisable; and

          (ii) If the aggregate sum of all Total Profit received (including the
     present value of any amounts to be received under any note or installment
     purchase agreement or deferred purchase price arrangement) by any and all
     Transferring Persons from all of the Disposition Transactions theretofore
     consummated exceeded the Aggregate Profit Ceiling, then such Transferring
     Persons shall be jointly and severally liable to pay to the Issuer or the
     Substitute Issuer, as the case may be, not later than the tenth (10th) day
     following the Option Termination Date (A) an amount in cash equal to the
     difference between such aggregate sum of the Total Profit and the Aggregate
     Profit Ceiling, (B) Option Shares (if delivered to the Issuer) or
     Substitute Securities (if delivered to a Substitute Issuer) having a market
     value as of that date equal difference between such aggregate sum of the
     Total Profit and the Aggregate Profit Ceiling, or (C) any combination of
     the foregoing.

Although not required for any cessation of exerciseability of the remaining
portion of this Option or any Substitute Option to become and be effective on
the Option Termination Date, the Grantee or any other Holder of any unexercised
portion of the Option or Substitute Option then outstanding shall forthwith
return any originally signed copy of this Agreement, or of any other agreement
issued in substitution therefor, that evidences such unexercised portion of the
Option or any Substitute Option that is in its possession to the Issuer or
Substitute Issuer, as the case may be. In order to secure the rights of the
Issuer and any Substitute Issuer hereunder, this Option Agreement or any
agreement issued in substitution or replacement therefor, that evidences any
unexercised portion of the Option or any Substitute Option shall contain the
legend set forth at the beginning of this Stock Option Agreement, and each
certificate evidencing any Option Shares or Substitute Securities shall contain
the legend set forth on Schedule A hereto; provided, however, that the Issuer or
Substitute Issuer, as applicable, shall remove any such legend from any Option
Shares or Substitute Securities promptly following any request made by the Owner
at any time after the Option Termination Date.

     (e) Notwithstanding anything to the contrary contained herein, no sale,
transfer or other disposition of any Option Shares or Substitute Securities made
after the Option Termination Date shall be subject to the constraints on Total
Profit contained in this Section 14 or shall otherwise obligate the transferror
of such Option Shares or Substitute Securities to pay back to the Issuer or the
Substitute Issuer any portion of any proceeds received therefor from any
Disposition Transaction, or any other transaction, in either case occurring
after the Option Termination Date.

     15. The parties hereto acknowledge that damages would be an inadequate
remedy for a breach 


                                      B-12
<PAGE>   150
APPENDIX B


of this Agreement by either party hereto and that the obligations of the parties
hereto shall be enforceable by either party hereto through injunctive or other
equitable relief.

     16. If any term, provision, covenant or restriction contained in this
Agreement is held by a court or other Governmental Entity of competent
jurisdiction to be invalid, void or unenforceable, the remainder of the terms,
provisions and covenants and restrictions contained in this Agreement shall
remain in full force and effect, and shall in no way be affected, impaired or
invalidated. If for any reason such court or Governmental Entity determines that
the Holder is not permitted to acquire, or Issuer is not permitted to repurchase
pursuant to Section 7, the full number of shares of Common Stock provided in
Section 1(a) hereof (as adjusted pursuant to Section 1(b) or 5 hereof), it is
the express intention of Issuer to allow the Holder to acquire or to require
Issuer to repurchase such lesser number of shares as may be permissible, without
any amendment or modification hereof.

     17. All notices, requests, claims, demands and other communications
hereunder shall be deemed to have been duly given when delivered in person, by
fax, telecopy, or by registered or certified mail (postage prepaid, return
receipt requested) at the respective addresses of the parties set forth in the
Merger Agreement.

     18. This Agreement shall be governed by and construed in accordance with
the laws of the State of California, regardless of the laws that might otherwise
govern under applicable principles of conflicts of laws thereof.

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

     20. Except as otherwise expressly provided herein, each of the parties
hereto shall bear and pay all costs and expenses incurred by it or on its behalf
in connection with the transactions contemplated hereunder, including fees and
expenses of its own financial consultants, investment bankers, accountants and
counsel.

     21. Except as otherwise expressly provided herein or in the Merger
Agreement, this Agreement contains the entire agreement between the parties with
respect to the transactions contemplated hereunder and supersedes all prior
arrangements or understandings with respect thereof, written or oral. Subject to
Section 12, the terms and conditions of this Agreement shall inure to the
benefit of and be binding upon the parties hereto and their respective
successors and permitted assignees. Nothing in this Agreement, expressed or
implied, is intended to confer upon any party, other than the parties hereto,
and their respective successors except as assignees, any rights, remedies,
obligations or liabilities under or by reason of this Agreement, except as
expressly provided herein.

Board of Directors
Eldorado Bancorp
19200 Von Karmon
Irvine, California  92612

Members of the Board:

We understand that Eldorado Bancorp, Irvine, California, ("Eldorado") and
Commerce Security Bancorp, Inc., Huntington Beach, California, ("CSBI") entered
into an Agreement and Plan of Merger (the "Agreement"), which provides, among
other things, for the acquisition of all of the capital stock of Eldorado and
its operating subsidiary, Eldorado Bank, by means of a merger of a direct or
indirect subsidiary of CSBI with and into Eldorado. Pursuant to the Agreement at
the Effective Time, each share of Common Stock, issued and outstanding prior to
the Effective Time, excluding Dissenting Shares and Excluded Shares, shall, by
virtue of the Merger and without any action on the part of the holder thereof,
be converted into the right to receive, in cash, the sum of $23.00 ( the "Merger
Consideration"). Furthermore, immediately prior to the Effective Time, each
holder of a then-outstanding Option shall be entitled to receive, in
cancellation of such option, a cash payment in an amount equal to the excess of
the Merger Consideration over the per-share exercise price of such Option,
multiplied by the number of shares of Common Stock covered by such Option,
subject to any required withholding of Taxes.

You have requested our opinion, as an independent financial advisor, as to
whether the Merger Consideration to be received by Eldorado's Common
Shareholders is fair from a financial point of view to the holders of Eldorado's
Common Stock as of the date hereof.

In connection with our opinion, we have: (i) reviewed a copy of the Agreement;
(ii) reviewed certain publicly available financial statements including audited
financial statements as of December 31, 1995 and 1994, Form 10-K as of December
31, 1995, Form 10-Q as of March 31, June 30 and September 30, 1996 and other
information of Eldorado; (iii) reviewed certain internal financial statements
and other financial and operating data concerning Eldorado; (iv) analyzed
certain financial projections of 


                                      C-1
<PAGE>   154
Eldorado prepared by the management of Eldorado; (v) discussed the past and
current operations and financial condition and the prospects of Eldorado with
senior executives; (vi) compared Eldorado from a financial point of view with
certain other companies which we deemed to be relevant; (vii) reviewed the
financial terms, to the extent publicly available, of certain comparable merger
transactions; (viii) reviewed the market prices and historical trading activity
of Eldorado; and (ix) performed such other analyses and examinations as we have
deemed appropriate.

We have assumed and relied upon without independent verification the accuracy
and completeness of the information reviewed by us for the purposes of this
opinion. We have not made an independent evaluation of the assets or liabilities
of Eldorado, nor have we been furnished with any such appraisals. In addition,
we are not an expert in the evaluation of loan portfolios for the purposes of
assessing the adequacy of the allowance for losses with respect thereto and have
assumed that such allowances for each of the companies are in the aggregate
adequate to cover such losses. With respect to financial forecasts, we have
assumed that they have been reasonably prepared and reflect the best currently
available estimates and judgments of management of Eldorado, as to the future
financial performance of Eldorado, respectively, and we have assumed such
forecasts and projections will be realized in the amounts and at the times
contemplated thereby. We have reviewed the form and content of the Letter of
Intent and Subscription Agreements made by new and existing investors,
respectively, in CSBI regarding the commitments to fund the Merger
Consideration. The total of the Letter of Intent and Subscription Agreements are
sufficient to complete the Merger if delivered as represented; however, we
express no legal opinion on Eldorado's and CSBI's ability to enforce such Letter
of Intent and Subscription Agreements. We have also assumed that obtaining any
necessary regulatory approvals and third party consents for the merger or
otherwise will not have an adverse effect on Eldorado, CSBI or the combined
company pursuant to the Merger.

Our opinion is necessarily based on economic, market and other condition as in
effect on, and the information made available to us as of the data hereof.
Events occurring after the date hereof could materially affect the assumptions
used in preparing this opinion.

In addition, Alex Sheshunoff & Co. Investment Banking was engaged by Eldorado on
August 1, 1996 to serve as Eldorado's exclusive financial advisor to undertake
the following: (a) develop, update and review with Eldorado on an on-going basis
a list of parties which might be interested in acquiring Eldorado and contact
parties on that list as approved by Eldorado in its sole discretion; (b) assist
in the preparation of a descriptive 



                                      C-2
<PAGE>   155
memorandum of Eldorado; (c) consult with and advise Eldorado concerning
opportunities for the sale of Eldorado, participate on Eldorado's behalf in
negotiations for such sale and assist and advise Eldorado concerning the value
of any Non-Merger Considerations offered by prospective acquirors; and (d) if
requested by Eldorado, render an opinion with respect to the fairness, from a
financial point of view, to Eldorado's shareholders of the consideration
received. For these services, Alex Sheshunoff & Co. Investment Banking will be
paid a professional fee of $592,261 upon closing of the merger with CSBI.

In addition, Alex Sheshunoff Management Services previously provided
professional services to Eldorado and its subsidiary bank, including earnings
assessments, product profitability analysis, management change analysis, profit
improvement analysis, trust analysis and educational programs. For these
services, Alex Sheshunoff Management Services was paid total professional fees
of $487,015.

Our opinion is limited to the fairness, from a financial point of view, to the
holders of Eldorado's Common Stock of the terms of the Merger and does not
address Eldorado's underlying business decision to undertake the Merger.
Moreover, this letter, and the opinion expressed herein, does not constitute a
recommendation to any stockholder as to any approval of the Merger or the
Agreement. It is understood that this letter is for the information of the Board
of Directors of Eldorado and may not be used for any other purpose without our
prior written consent, except that this opinion may be included in its entirety
in any filing made by Eldorado with the Securities and Exchange Commission with
respect to the Merger.

Based upon and subject to the foregoing, we are of the opinion that, as of the
date hereof, the Merger Consideration to be received by Eldorado's Common
shareholders is fair from a financial point of view to the holders of such
shares.


                                        Very truly yours,




                                        ALEX SHESHUNOFF & CO.

APPENDIX D

              CHAPTER 13 OF THE CALIFORNIA GENERAL CORPORATION LAW
                               DISSENTERS' RIGHTS

SECTION 1300. RIGHT TO REQUIRE PURCHASE--"DISSENTING SHARES" AND "DISSENTING
SHAREHOLDER" DEFINED.

      (a)  If the approval of the outstanding shares (Section 152) of a
corporation is required for a reorganization under subdivisions (a) and (b) or
subdivision (e) or (f) of Section 1201, each shareholder of the corporation
entitled to vote on the transaction and each shareholder of a subsidiary
corporation in a short-form merger may, by complying with this chapter, require
the corporation in which the shareholder holds shares to purchase for cash at
their fair market value the shares owned by the shareholder which are dissenting
shares as defined in subdivision (b). The fair market value shall be determined
as of the day before the first announcement of the terms of the proposed
reorganization or short-form merger, excluding any appreciation or depreciation
in consequence of the proposed action, but adjusted for any stock split, reverse
stock split, or share dividend which becomes effective thereafter.

      (b)  As used in this chapter, "dissenting shares" means shares which come
within all of the following descriptions:

           (1)   Which were not immediately prior to the reorganization or
      short-form merger either (A) listed on any national securities exchange
      certified by the Commissioner of Corporations under subdivision (o) of
      Section 25100 or (B) listed on the list of OTC margin stocks issued by the
      Board of Governors of the Federal Reserve System, and the notice of
      meeting of shareholders to act upon the reorganization summarizes this
      section and Sections 1301, 1302, 1303 and 1304; provided, however, that
      this provision does not apply to any shares with respect to which there
      exists any restriction on transfer imposed by the corporation or by any
      law or regulation; and provided, further, that this provision does not
      apply to any class of shares described in subparagraph (A) or (B) if
      demands for payment are filed with respect to 5 percent or more of the
      outstanding shares of that class.

           (2)   Which were outstanding on the date for the determination of
      shareholders entitled to vote on the reorganization and (A) were not voted
      in favor of the reorganization or, (B) if described in subparagraph (A) or
      (B) of paragraph (1) (without regard to the provisos in that paragraph),
      were voted against the reorganization, or which were held of record on the
      effective date of a short-form merger; provided, however, that
      subparagraph (A) rather than subparagraph (B) of this paragraph applies in
      any case where the approval required by Section 1201 is sought by written
      consent rather than at a meeting.

           (3)   Which the dissenting shareholder has demanded that the
      corporation purchase at their fair market value, in accordance with
      Section 1301.

           (4)   Which the dissenting shareholder has submitted for endorsement,
      in accordance with Section 1302.

      (c)  As used in this chapter, "dissenting shareholder" means the
recordholder of dissenting shares and includes a transferee of record.

SECTION 1301.  DEMAND FOR PURCHASE.

      (a) If, in the case of a reorganization, any shareholders of a corporation
have a right under Section 1300, subject to compliance with paragraphs (3) and
(4) of subdivision (b) thereof, to require the corporation to purchase their
shares for cash, such corporation shall mail to each such shareholder a notice
of the approval of the reorganization by its outstanding shares (Section 152)
within 10 days after the date of such approval, accompanied by a copy of
Sections 1300, 1302, 1303, 1304 and this section, a statement of the price
determined by the corporation to represent the fair market value of the
dissenting shares, and a brief description of the procedure to be followed if
the shareholder desires to exercise the shareholder's right under such sections.
The statement of price constitutes an offer by the corporation to purchase at
the 


                                      D-1
<PAGE>   157
price stated any dissenting shares as defined in subdivision (b) of Section
1300, unless they lose their status as dissenting shares under Section 1309.

      (b) Any shareholder who has a right to require the corporation to purchase
the shareholder's shares for cash under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon
the reorganization, or (2) in any other case within 30 days after the date on
which the notice of the approval by the outstanding shares pursuant to
subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder.

      (c) The demand shall state the number and class of the shares held of
record by the shareholder which the shareholder demands that the corporation
purchase and shall contain a statement of what such shareholder claims to be the
fair market value of those shares as of the day before the announcement of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.

SECTION 1302. ENDORSEMENT OF SHARES.

      Within 30 days after the date on which notice of the approval by the
outstanding shares or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder, the shareholder shall submit to the corporation at
its principal office or at the office of any transfer agent thereof, (a) if the
shares are certificated securities, the shareholder's certificates representing
any shares which the shareholder demands that the corporation purchase, to be
stamped or endorsed with a statement that the shares are dissenting shares or to
be exchanged for certificates of appropriate denomination so stamped or endorsed
or (b) if the shares are uncertificated securities, written notice of the number
of shares which the shareholder demands that the corporation purchase. Upon
subsequent transfers of the dissenting shares on the books of the corporation,
the new certificates, initial transaction statement, and other written
statements issued therefor shall bear a like statement, together with the name
of the original dissenting holder of the shares.

SECTION 1303. AGREED PRICE--TIME FOR PAYMENT.

      (a) If the corporation and the shareholder agree that the shares are
dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the fair
market value of any dissenting shares as between the corporation and the holders
thereof shall be filed with the secretary of the corporation.

      (b) Subject to the provisions of Section 1306, payment of the fair market
value of dissenting shares shall be made within 30 days after the amount thereof
has been agreed or within 30 days after any statutory or contractual conditions
to the reorganization are satisfied, whichever is later, and in the case of
certificated securities, subject to surrender of the certificates therefor,
unless provided otherwise by agreement.

SECTION 1304. DISSENTER'S ACTION TO ENFORCE PAYMENT

      (a) If the corporation denies that the shares are dissenting shares, or
the corporation and the shareholder fail to agree upon the fair market value of
the shares, then the shareholder demanding purchase of such shares as dissenting
shares or any interested corporation, within six months after the date on which
notice of the approval by the outstanding shares (Section 152) or notice
pursuant to subdivision (i) of Section 1110 was mailed to the shareholder, but
not thereafter, may file a complaint in the superior court of the proper county
praying the court to determine whether the shares are dissenting shares or the
fair market value of the dissenting shares or both or may intervene in any
action pending on such a complaint.

                                      D-2
<PAGE>   158
      (b) Two or more dissenting shareholders may join as plaintiffs or be
joined as defendants in any such action and two or more such actions may be
consolidated.

      (c) On the trial of the action, the court shall determine the issues. If
the status of the shares as dissenting shares is in issue, the court shall first
determine that issue. If the fair market value of the dissenting shares is in
issue, the court shall determine, or shall appoint one or more impartial
appraisers to determine, the fair market value of the shares.

SECTION 1305. APPRAISERS' REPORT--PAYMENT--COSTS.

      (a) If the court appoints an appraiser or appraisers, they shall proceed
forthwith to determine the fair market value per share. Within the time fixed by
the court, the appraisers, or a majority of them, shall make and file a report
in the office of the clerk of the court. Thereupon, on the motion of any party,
the report shall be submitted to the court and considered on such evidence as
the court considers relevant. If the court finds the report reasonable, the
court may confirm it.

      (b) If a majority of the appraisers appointed fail to make and file a
report within 10 days from the date of their appointment or within such further
time as may be allowed by the court or the report is not confirmed by the court,
the court shall determine the fair market value of the dissenting shares.

      (c) Subject to the provisions of Section 1306, judgment shall be rendered
against the corporation for payment of an amount equal to the fair market value
of each dissenting share multiplied by the number of dissenting shares which any
dissenting shareholder who is a party, or who has intervened, is entitled to
require the corporation to purchase, with interest thereon at the legal rate
from the date on which judgment was entered.

      (d) Any such judgment shall be payable forthwith with respect to
uncertificated securities and, with respect to certificated securities, only
upon the endorsement and delivery to the corporation of the certificates for the
shares described in the judgment. Any party may appeal from the judgment.

      (e) The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interest
at the legal rate on judgments from the date of compliance with Sections 1300,
1301 and 1302 if the value awarded by the court for the shares is more than 125
percent of the price offered by the corporation under subdivision (a) of Section
1301).

SECTION 1306. DISSENTING SHAREHOLDER'S STATUS AS CREDITOR.

      To the extent that the provisions of Chapter 5 prevent the payment to any
holders of dissenting shares of their fair market value, they shall become
creditors of the corporation for the amount thereof together with interest at
the legal rate on judgments until the date of payment, but subordinate to all
other creditors in any liquidation proceeding, such debt to be payable when
permissible under the provisions of Chapter 5.

SECTION 1307. DIVIDENDS PAID AS CREDIT AGAINST PAYMENT.

      Cash dividends declared and paid by the corporation upon the dissenting
shares after the date of approval of the reorganization by the outstanding
shares (Section 152) and prior to payment for the shares by the corporation
shall be credited against the total amount to be paid by the corporation
therefor. 

SECTION 1308. CONTINUING RIGHTS AND PRIVILEGES OF DISSENTING SHAREHOLDERS.

      Except as expressly limited in this chapter, holders of dissenting shares
continue to have all the rights and privileges incident to their shares, until
the fair market value of their shares is agreed upon or determined. A dissenting
shareholder may not withdraw a demand for payment unless the corporation
consents thereto.

                                      D-3
<PAGE>   159
SECTION 1309. TERMINATION OF DISSENTING SHAREHOLDER STATUS.

      Dissenting shares lose their status as dissenting shares and the holders
thereof cease to be dissenting shareholders and cease to be entitled to require
the corporation to purchase their shares upon the happening of any of the
following:

      (a) The corporation abandons the reorganization. Upon abandonment of the
reorganization, the corporation shall pay on demand to any dissenting
shareholder who has initiated proceedings in good faith under this chapter all
necessary expenses incurred in such proceedings and reasonable attorneys' fees.

      (b) The shares are transferred prior to their submission for endorsement
in accordance with Section 1302 or are surrendered for conversion into shares of
another class in accordance with the articles.

      (c) The dissenting shareholder and the corporation do not agree upon the
status of the shares as dissenting shares or upon the purchase price of the
shares, and neither files a complaint or intervenes in a pending action as
provided in Section 1304, within six months after the date on which notice of
the approval by the outstanding shares or notice pursuant to subdivision (i) of
Section 1110 was mailed to the shareholder.

      (d) The dissenting shareholder, with the consent of the corporation,
withdraws the shareholder's demand for purchase of the dissenting shares.

SECTION 1310. SUSPENSION OF PROCEEDINGS FOR PAYMENT PENDING LITIGATION

      If litigation is instituted to test the sufficiency or regularity of the
votes of the shareholders in authorizing a reorganization, any proceedings under
Sections 1304 and 1305 shall be suspended until final determination of such
litigation. SECTION 1311. EXEMPT SHARES.

      This chapter, except Section 1312, does not apply to classes of shares
whose terms and provisions specifically set forth the amount to be paid in
respect to such shares in the event of a reorganization or merger.

SECTION 1312. ATTACKING VALIDITY OF REORGANIZATION OR MERGER.

      (a) No shareholder of a corporation who has a right under this chapter to
demand payment of cash for the shares held by the shareholder shall have any
right at law or in equity to attack the validity of the reorganization or
short-form merger, or to have the reorganization or short-form merger set aside
or rescinded, except in an action to test whether the number of shares required
to authorize or approve the reorganization have been legally voted in favor
thereof; but any holder of shares of a class whose terms and provisions
specifically set forth the amount to be paid in respect to them in the event of
a reorganization or short-form merger is entitled to payment in accordance with
those terms and provisions or, if the principal terms of the reorganization are
approved pursuant to subdivision (b) of Section 1202, is entitled to payment in
accordance with the terms and provisions of the approved reorganization.

      (b) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash for
such shareholder's shares pursuant to this chapter; but if the shareholder
institutes any action to attack the validity of the reorganization or short-form
merger or to have the reorganization or short- form merger set aside or
rescinded, the shareholder shall not thereafter have any right to demand payment
of cash for the shareholder's shares pursuant to this chapter. The court in any
action attacking the validity of the reorganization or short-form merger or to
have the reorganization or short-form merger set aside or rescinded shall not
restrain or enjoin the consummation of the transaction except upon 10 days'
prior notice to the corporation and upon a determination by the court that
clearly no other remedy will adequately protect the complaining shareholder or
the class of shareholders of which such shareholder is a member.


                                      D-4
<PAGE>   160
      (c) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, in any action to attack the
validity of the reorganization or short-form merger or to have the
reorganization or short-form merger set aside or rescinded, (1) a party to a
reorganization or short-form merger which controls another party to the
reorganization or short-form merger shall have the burden of proving that the
transaction is just and reasonable as to the shareholders of the controlled
party, and (2) a person who controls two or more parties to a reorganization
shall have the burden of proving that the transaction is just and reasonable as
to the shareholders of any party so controlled.
