Item 5. Other Events
        ------------

        On December 24, 1996, Eldorado Bancorp ("Eldorado" or the "Registrant")
and Commerce Security Bancorp, Inc., a Delaware corporation ("CSBI"), entered
into an Agreement and Plan of Merger (the "Merger Agreement"). That Agreement
provides for CSBI to acquire, by means of a merger of Eldorado and a
wholly-owned subsidiary of CSBI (the "Merger"), 100% of the outstanding common
stock of the Registrant for cash consideration of $23 per share (the "Merger
Price"). On consummation of the Merger, each outstanding share of Eldorado will
be converted into a right to receive $23 in cash and all outstanding stock
options held by directors, officers and other employees of Eldorado will be
cancelled in exchange for cash in an amount equal to the difference between $23
and the exercise price per common share covered by such options.

        In connection with the execution of the Merger Agreement, Eldorado
entered into a Stock Option Agreement with CSBI (the "Option Agreement"). That
Option Agreement grants to CSBI an option (the "CSBI Option") that will entitle
it to purchase, at an exercise price equal to $22 per share, up to a number of
shares of Eldorado's common stock that, if exercised, would represent 11% of
Eldorado's then outstanding shares. The CSBI Option will become exercisable
only if Eldorado's Board of Directors were to determine, in the exercise of
its fiduciary duties, to accept or recommend to shareholders that they approve
a merger or other strategic transaction by Eldorado with another entity and
the Board's action were to result in termination of the Merger Agreement. The
CSBI Option will terminate, without having become exercisable, in the event the
Merger Agreement is terminated for any other reason or the Merger is
consummated.

        Consummation of the Merger is contingent upon, among other things, the
receipt by CSBI of approvals of the Merger from state and federal banking
regulatory agencies and the approval of the principal terms of the Merger
Agreement and the Merger by Eldorado's shareholders. Eldorado has been informed
that directors of Eldorado who own, in the aggregate, approximately 19.8% of
Eldorado's outstanding shares, in their individual capacities and not as
directors, have entered into Voting Agreements with CSBI, whereby those
directors have agreed that they will vote their Eldorado shares for approval of
the Merger Agreement and the Merger at the meeting of shareholders to be held to
vote on the Merger and, provided the Merger Agreement has not been terminated,
against any other proposal that would interfere with the consummation of the
Merger.

        In addition, CSBI has entered into preliminary agreements with third
parties to obtain the financing it needs to fund the Merger consideration. Under
the Merger Agreement, if CSBI is unable to raise such financing by August 1,
1997, the final date set forth in the Merger Agreement for obtaining such
financing, or certain other events occur that result in termination of the
Merger Agreement, then, Eldorado will receive payment of a good faith cash
deposit of $4,500,000 placed in an escrow account by CSBI pursuant to the terms
of a Deposit Escrow Agreement dated as of December 24, 1996, among CSBI,
Eldorado and First Trust of California, National Association, as escrow agent.

        The foregoing summaries of the Merger Agreement, the Stock Option
Agreement, the Voting Agreements and the Deposit Escrow Agreements are
qualified by the complete copies thereof, which are included as Exhibits to
this Report.

                                   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 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.

<PAGE>   10
               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.

<PAGE>   11
        2.4       EXCHANGE OF CERTIFICATES.

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

                                       11
<PAGE>   12
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.

        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

                                       12
<PAGE>   13
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.

requesting (or considering the appropriateness of issuing or requesting) any
such Regulatory Agreement. Except as disclosed on Schedule 3.8, there exists no
material unresolved violation, criticism or exception identified by any Bank
Regulator with respect to any report or statement of Eldorado, or relating to
any examination of Eldorado.

        3.9 UNDISCLOSED LIABILITIES. Except (a) as and to the extent reflected
in the Most Recent Financial Statements, (b) as and to the extent reflected on
Schedule 3.9, (c) obligations (including guarantees and letters of credit) not
required by GAAP to be reflected, reserved against or disclosed in the Most
Recent Financial Statements, all of which obligations are set forth on Schedule
3.9 and none of which, individually or in the aggregate, could reasonably be
expected to have a Material Adverse Effect, and (d) obligations incurred in the
ordinary course of business consistent with past practice since the Most Recent
Balance Sheet Date, Eldorado 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.

        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)

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 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.

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

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

is not party to (nor are any of its assets bound by) any material oral or

relating to non-competition or secrecy, (f) that materially restricts the

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

of California, and has paid all fees and assessments due and payable in
connection therewith. Except for normal examinations conducted by a Bank
Regulator in the regular course of CSBI's the applicable CSBI Subsidiary
Predecessor's business or as disclosed on Schedule 4.7, no Bank Regulator has
initiated any proceeding or investigation into the business or operations of
CSBI or, to CSBI's Knowledge, any CSBI Subsidiary Predecessor, since December
31, 1993 or, to CSBI's Knowledge, is currently contemplating the initiation of
any proceeding or investigation. Except as disclosed


                                       26
<PAGE>   27
on Schedule 4.7, CSBI is not a party to or subject to any Regulatory Agreement
with or from any Bank Regulator that restricts the conduct of CSBI's business or
in any manner relates to its capital adequacy, credit policies, loan origination
practices or management nor has CSBI been notified that any Bank Regulator is
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
$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


                                       28
<PAGE>   29
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.

               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


                                       29
<PAGE>   30
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.

        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


                                       30
<PAGE>   31
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 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


                                       31
<PAGE>   32
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


                                       32
<PAGE>   33
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 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


                                       33
<PAGE>   34
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 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


                                       34
<PAGE>   35
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
(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;


                                       35
<PAGE>   36
               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

        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

                                       38
<PAGE>   39
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), 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


                                       39
<PAGE>   40
"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


                                       40
<PAGE>   41
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 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


                                       41
<PAGE>   42
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 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


                                       42
<PAGE>   43
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 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


                                       43
<PAGE>   44
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


                                       44
<PAGE>   45
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, 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.


                                       45
<PAGE>   46
               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 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.

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

<PAGE>   47
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.

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

agreement.

Stock owned by Persons who have made a demand for purchase under Section 1301 of

each Person (other than the Governmental Entities referred to in Section 6.1.2)
whose consent, approval or waiver shall be required in order to permit the
consummation of the Merger or the preservation of the contractual rights of
Eldorado with respect to its business shall have been obtained, except where the
failure to obtain such consent, approval or waiver would not have a Material
Adverse Effect on the economic or business benefits to CSBI of the Merger so as
to render inadvisable the consummation of the Merger in the reasonable judgment
of CSBI.

the Closing solely by the following means and with the following effects:

        7.1 BY MUTUAL AGREEMENT. Eldorado and CSBI (on behalf of itself and
Merger Sub) may terminate this Agreement by mutual written consent at any time.

        7.2 REGULATORY IMPEDIMENT. Either CSBI (on behalf of itself and Merger
Sub) or Eldorado may unilaterally terminate this Agreement at any time prior to
the Closing if (a) a Bank Regulator shall have made a final determination
denying an application of either Party the granting of which is essential to the
consummation of the Merger, or (b) the occurrence of the Closing would violate
any final order, decree or judgment of any court having competent jurisdiction,
provided, that CSBI shall reimburse Eldorado for Eldorado's reasonable and
documented Expenses, not to exceed $400,000, unless the basis for such
termination is (x) a Bank Regulator's denial of an 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) based on actions (or
failures to act) by Eldorado, or (iii) based on an agreement to which Eldorado
is a party or by which any of Eldorado's assets are bound.

        7.3 BY CSBI. CSBI (on behalf of itself and Merger Sub) may unilaterally
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
reasonable determination of CSBI, cause the failure of the condition set forth
in Section 6.2.3, in either case such termination to take effect ten (10)
Business Days following notice to Eldorado identifying such breach or failure if
such breach or failure has not been cured prior to the expiration of such
period;

               7.3.2 upon notice to Eldorado given within the period provided
therefor in Section 5.1.4 if (a) Eldorado has not reaffirmed its intent to
proceed with the Merger within the time provided therefor in Section 5.1.4
following its receipt of a Qualifying Strategic Transaction Proposal, or (b) the
Board of Directors fails to give its Recommendation of Approval to the
Shareholders, or withdraws its Recommendation of Approval prior to the
affirmative vote of the


                                       50
<PAGE>   51
Shareholders, whether or not such failure or withdrawal is permitted under
Section 5.2.2, provided that in the case of a termination under this Section
7.3.2, CSBI shall be entitled to receive from Eldorado the Termination Fee;

               7.3.3 upon notice to Eldorado, if any of the conditions to the

set forth in Section 6.2.1 or Section 6.2.2 as of the Closing;

               7.3.4 upon notice to Eldorado at any time after 12:00 noon
(Pacific time) on August 1, 1997, if the Closing shall not have occurred prior
to such date and time, unless (a) such failure results primarily from CSBI
breaching any 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 termination is CSBI's reimbursement of Eldorado's
reasonable and documented Expenses, not to exceed $400,000.

        7.4 BY ELDORADO. Eldorado may unilaterally terminate this Agreement:

               7.4.1 if CSBI has failed to perform, satisfy or comply with in
any material respect any of its agreements and covenants contained in this
Agreement (including a failure timely to furnish assurances of continued
availability of the Merger Financing and/or evidence of Merger Financing as
provided in Section 5.12.3, including as such Section incorporates Section
5.12.2 regarding the Remaining Financing Commitments), such termination to take
effect (a) if such failure is with respect to Section 5.12.3, at the end of the
period set forth in such Section, and (b) if such failure is with respect to any
other Section, ten (10) Business Days following notice to CSBI identifying such
breach or failure if such breach or failure has not been cured prior to the
expiration of such period;

Strategic Transaction Proposal; provided, however, that a condition to the
effectiveness of any termination pursuant to this Section 7.4.2 is the payment
of the Termination Fee to CSBI by Eldorado;


                                       51
<PAGE>   52
               7.4.3 upon notice to CSBI if the Shareholders fail to approve the
Merger by the requisite votes required by Law at a Shareholders Meeting;
provided, however, that a condition to the effectiveness of any termination
pursuant to this Section 7.4.3 is Eldorado's payment of CSBI's reasonable and
documented Expenses, not to exceed $400,000, unless CSBI shall have voted any
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
may not terminate the Agreement pursuant to this Section 7.4.3 if prior to the
meeting of Shareholders the Board of Directors has not given, or has given but

time, unless (a) the failure results primarily from Eldorado breaching any 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, however, that (x) if the basis for such termination is the failure of
the Shareholders to approve the Merger, a condition to the effectiveness of such
termination is Eldorado's payment of 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,

hereunder, except that (a) the provisions of Section 5.3 relating to

termination, and (b) notwithstanding anything else to the contrary contained
herein, but subject in all events to the immediately following sentence, neither
Party shall be relieved of or released from any liability or damages arising out

the event that either Party has breached this Agreement by the inaccuracy, as of
the date when made, of a representation or warranty made herein by such Party,
such Party shall not be liable to the other Party for damages unless (i) one or
more of the breaching Party's officers identified in the definition of
"Eldorado's Knowledge" or "CSBI's Knowledge", as applicable, knew or reasonably
should have known of such inaccuracy as of the date of this Agreement, and (ii)
the facts causing such inaccuracy, individually or in the aggregate with all
other facts causing other representations or warranties to be inaccurate, shall
not have resulted in or constitute, and could not reasonably be expected to
result in or constitute, in the case of Eldorado, a Material Adverse Effect on
Eldorado, prior to or after the Merger (and assuming for purposes of this clause
that the Merger Sub has no assets, liabilities or operations), or on Eldorado's
ability to consummate the Merger, and in the case of CSBI, a Material Adverse
Effect on CSBI's ability to consummate the Merger.

hereunder or now or hereafter existing at law or in equity.

               7.6.3 Certain Remedies Exclusive.

                  (a) If this Agreement is properly terminated under Section

Business Days of the notice of termination, in the case of Section 7.4.2, or
(ii) within ten Business Days of the notice of termination, in the case of
Section 7.3.2, then CSBI's receipt and acceptance of the Termination Fee shall
constitute an exclusive remedy, and following such receipt and acceptance CSBI
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
Persons' compliance with the provisions of Section 5.3 relating to Confidential

                  (b) If (i) this Agreement is properly terminated under Section

failure to approve the Merger, (ii) CSBI has not asserted a breach of this
Agreement by Eldorado at or before the time CSBI


                                       53
<PAGE>   54

Section, and (iii) Eldorado reimburses CSBI's Expenses (subject to the cap
specified in such Section) within ten (10) Business Days after Eldorado's
receipt of the invoice therefor (which period shall be extended by an additional
reasonable time if Eldorado has reasonably disputed the amount of such
obligations), then CSBI's timely receipt of such reimbursement shall constitute
an exclusive remedy except as provided in Section 7.5.2, and following such
receipt and acceptance CSBI 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 Persons' compliance with the provisions of Section 5.3
relating to Confidential Information).

                  (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 shall constitute an exclusive remedy, and following such receipt
and acceptance Eldorado 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 CSBI or any of its affiliates or investors (other than with respect
to such Persons' compliance with the provisions of Section 5.3 relating to
Confidential Information).

              (a) Each share of Merger Sub Stock which is outstanding
immediately prior the Effective Time of the Merger shall be converted at the
Effective Time of the Merger into one share of Eldorado Common Stock.

              (b) Each share of Eldorado Common Stock (except for shares, if
any, which shall then or thereafter constitute "dissenting shares" within the
meaning of Section 1300 of the California Corporations Code ("Dissenting
Eldorado Shares") and those shares of Merger Sub Common Stock converted to

                            DEPOSIT ESCROW AGREEMENT


         THIS DEPOSIT ESCROW AGREEMENT (this "Escrow Agreement"), dated as of
December 24, 1996, is made by and among COMMERCE SECURITY BANCORP, INC., a
Delaware corporation ("CSBI"), ELDORADO BANCORP, a California corporation
("Eldorado"), and FIRST TRUST OF CALIFORNIA, NATIONAL ASSOCIATION, as escrow
agent (the "Escrow Agent").

                                R E C I T A L S :

         A. Concurrently with the execution and delivery of this Escrow
Agreement, CSBI and Eldorado have entered into an Agreement and Plan of Merger,
dated as of even date herewith (the "Agreement"), pursuant to which CSBI has
agreed, among other things, to acquire all of the issued and outstanding stock
of Eldorado by means of a cash merger.

         B. The Agreement requires that CSBI and Eldorado enter into this Escrow
Agreement with the Escrow Agent and that CSBI deposit an amount equal to
$4,500,000 with the Escrow Agent for distribution hereafter on the terms and
conditions set forth in this Escrow Agreement.

         NOW, THEREFORE, in consideration of the foregoing premises, the
following mutual covenants and promises and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereby agree as follows:

         1. Definitions. Capitalized terms used herein and not otherwise defined
herein shall have the respective meanings ascribed to such terms in the
Agreement.

         2. Appointment of Escrow Agent; Escrow Deposit. CSBI and Eldorado
hereby constitute and appoint the Escrow Agent as, and the Escrow Agent hereby
agrees to assume and perform the duties of, the escrow agent under and pursuant
to this Escrow Agreement. The Escrow Agent acknowledges receipt of (i) an
executed copy of the Agreement, and (ii) the sum of Four Million Five Hundred
Thousand and 00/100 Dollars (U.S. $4,500,000.00) (the "Escrow Deposit") from
CSBI, which CSBI is depositing with Escrow Agent in accordance with Section 2.7
of the Agreement.

         3. The Escrow. The Escrow Deposit and all earnings from the investment
thereof (collectively, the "Escrow Funds") shall be held by the Escrow Agent in
escrow number 95424480, which is a separate escrow which shall be maintained
pursuant to the terms of this Escrow Agreement (the "Escrow"). The Escrow Funds
shall be distributed by Escrow Agent in accordance with the terms and subject to
the conditions of this Escrow Agreement and, until distributed, the Escrow Funds
shall be invested in the manner hereinafter set forth in Section 4 hereof.
Neither the Escrow nor the Escrow Funds therein shall be subject to lien,
attachment, charge or encumbrance by any creditor of any party hereto and shall
be used solely for the purposes set forth in this Escrow Agreement.
<PAGE>   2
         4.       Investment of the Escrow Funds; Taxes.

                  (a) Investment of Escrow Funds. The Escrow Agent shall invest
and reinvest all cash funds held from time to time as part of the Escrow Funds
in ninety (90) day interest-bearing United States Treasury Securities ("U.S.
Treasuries") and, on maturity thereof, shall be reinvested in U.S. Treasuries.

                  (b) Earnings; Taxes. All earnings on the Escrow Funds shall
belong to the party to whom the Escrow Deposit is distributed pursuant to the
Agreement. Taxes in respect of such earnings shall be the obligation of and
shall be paid when due by such party, which shall indemnify and hold the other
party and Escrow Agent harmless from and against such taxes.

         5.       Disbursement of Escrow Funds; Procedures.

                  (a) Disbursement of Escrow Funds. The Escrow Agent will hold
the Escrow Funds in its possession until authorized hereunder to deliver such
Escrow Funds as follows:

                           (i) At the Closing, upon receipt of joint
instructions from CSBI and Eldorado to the effect that all conditions to closing
have been satisfied or waived, an amount equal to the Escrow Funds shall be
disbursed to the Exchange Agent and credited to the Merger Consideration payable
by CSBI under the Agreement.

                           (ii) If CSBI is entitled to the Escrow Deposit
pursuant to Section 2.7 of the Agreement, CSBI shall deliver a notice (the "CSBI
Termination Notice") which shall specify in reasonable detail the event or
circumstances giving rise to the termination of the Agreement and include CSBI's
demand for the Escrow Agent to disburse the remaining Escrow Funds to CSBI. Upon
receipt thereof, Escrow Agent shall promptly deliver a copy of the CSBI
Termination Notice to Eldorado. If Eldorado disputes CSBI's demand for the
remaining Escrow Funds, it shall so notify Escrow Agent in writing (with a copy
to CSBI) within 10 calendar days after the giving of such notice ("Notice
Period"). If Eldorado fails to deliver such written notice to Escrow Agent
within the Notice Period, Escrow Agent shall presume conclusively that Eldorado
has no objection to the disbursement of the remaining Escrow Funds to CSBI and
Escrow Agent shall promptly disburse the remaining Escrow Funds to CSBI.

                           (iii) If Eldorado is entitled to the Escrow Deposit
pursuant to Section 2.7 of the Agreement, Eldorado shall deliver a notice (the
"Eldorado Termination Notice") which shall specify in reasonable detail the
event or circumstances giving rise to the termination of the Agreement and
include Eldorado's demand for the Escrow Agent to disburse the Escrow Funds to
Eldorado. Upon receipt thereof, Escrow Agent shall promptly deliver a copy of
the Eldorado Termination Notice to CSBI. If CSBI disputes Eldorado's demand for
the remaining Escrow Funds, it shall so notify Escrow Agent in writing (with a
copy to Eldorado) within the Notice Period. If CSBI fails to deliver such
written notice to Escrow Agent within the Notice Period, Escrow Agent shall
presume conclusively that CSBI has no objection to the disbursement of the
remaining Escrow Funds to Eldorado and Escrow Agent shall promptly disburse the
remaining Escrow Funds to Eldorado.

                           (iv) If, within either Notice Period under
subparagraphs (ii) or (iii) above, Escrow Agent shall receive notice from
Eldorado or CSBI, as applicable, that there is a dispute with


                                        2
<PAGE>   3
respect to any demand for disbursement of the Escrow Funds, then the Escrow
Agent shall not disburse any portion of the Escrow Funds to either party pending
resolution under either clause (A) or clause (B) below, and the Escrow Agent,
Eldorado and CSBI shall proceed as follows:

                                    (A) Either CSBI or Eldorado may bring an
action to resolve the dispute in any court of competent jurisdiction in Orange
County, California. Upon receipt by the Escrow Agent of a court order or
judgment by a court of competent jurisdiction resolving the dispute, together
with evidence satisfactory to the Escrow Agent that such order or judgment has
become a final order from which no appeal has been or can be had (a "Final
Judgment"), the Escrow Agent shall promptly disburse the Escrow Funds in
accordance with the Final Judgment.

                                    (B) If CSBI and Eldorado agree to a
resolution of any such dispute before a Final Judgment relating thereto shall
occur, they shall by joint notice direct the Escrow Agent to make disbursements
from the Escrow Fund as they may agree. Upon receipt of such notice the Escrow
Agent shall promptly deliver such portion(s) of the Escrow Fund in accordance
with such joint instructions, and the dispute shall be deemed to have been
resolved.

                  (b) Disbursement Procedures. All disbursements of Escrow Funds
hereunder shall be made by wire transfer of immediately available funds to a
bank account designated by CSBI or Eldorado, as the case may be, in any written
notice delivered to Escrow Agent, unless Escrow Agent receives different
disbursement instructions in writing from CSBI or Eldorado specifically revoking
or amending any prior disbursement instructions given to the Escrow Agent by
such party. Escrow Agent shall promptly notify CSBI and Eldorado of all
disbursements pursuant to this Escrow Agreement, and the amount thereof.

                  (c) Agreement. CSBI and Eldorado acknowledge and agree that
all Escrow Funds distributed to Eldorado pursuant hereto shall be subject to the
terms and provisions of the Agreement.

         6. Liquidation of the Escrow Fund. Whenever the Escrow Agent shall be
required to make the payment from the Escrow Fund, the Escrow Agent shall pay
such amounts by liquidating the investment then constituting the Escrow Fund or
such portion thereof as the Escrow Agent deems appropriate in its absolute
discretion.

         7. Duties and Obligations of the Escrow Agent. The duties and
obligations of the Escrow Agent shall be limited to and determined solely by the
provisions of this Escrow Agreement and the certificates delivered in accordance
herewith, and the Escrow Agent is not charged with knowledge of or any duties or
responsibilities in respect of any other agreement or document. In furtherance
and not in limitation of the foregoing:

                           (i) the Escrow Agent makes no representation as to
                  the validity, value, genuineness or collectibility of any
                  security, document or instrument held by or delivered to it
                  and reasonably believed by the Escrow Agent to be valid and
                  genuine, and shall not be liable for any loss of interest
                  sustained as a result of investments made hereunder in
                  accordance with the terms hereof, including any liquidation of
                  any investment of the Escrow Funds prior to its maturity
                  effected in order to make a payment required by the terms of
                  this Escrow Agreement;


                                        3
<PAGE>   4
                           (ii) the Escrow Agent shall be fully protected in
                  relying in good faith upon any written certificate, notice,
                  direction, request, waiver, consent, receipt or other document
                  that the Escrow Agent reasonably believes to be genuine and
                  duly authorized, executed and delivered;

                           (iii) the Escrow Agent shall not be liable for any
                  error of judgment, or for any act done or omitted by it, or
                  for any mistake in fact or law, or for anything that it may do
                  or refrain from doing connection herewith; provided, however,
                  that notwithstanding any other provision in this Escrow
                  Agreement, the Escrow Agent shall be liable for its willful
                  misconduct or gross negligence or breach by Escrow Agent of
                  this Escrow Agreement unless the breach was unintentional and
                  the result of other than willful misconduct or gross
                  negligence; provided further, that CSBI and Eldorado shall,
                  jointly and severally, exonerate and indemnify the Escrow
                  Agent against all claims, suits, obligations, liabilities and
                  damages, including attorney's fees, based upon, arising out of
                  or resulting from the performance or non-performance by the
                  Escrow Agent of its obligations hereunder, unless such
                  performance or non-performance constitutes willful misconduct
                  or gross negligence;

                           (iv) the Escrow Agent may seek the advice of legal
                  counsel selected with reasonable care in the event of any
                  dispute or question as to the construction of any of the
                  provisions of this Escrow Agreement or its duties hereunder,
                  and it shall incur no liability and shall be fully protected
                  in respect of any action taken, omitted or suffered by it in
                  good faith in accordance with the opinion of such counsel;

                           (v) if a controversy arises between one or more of
                  the parties hereto, or between any of the parties hereto and
                  any person not a party hereto, as to whether or not or to whom
                  the Escrow Agent shall deliver any of the Escrow Funds or as
                  to any other matter arising out of or relating to the Escrow
                  Funds or this Escrow Agreement, the Escrow Agent shall not
                  determine the same and shall not make any delivery of the
                  Escrow Funds or any portion thereof but shall retain the
                  Escrow Funds until the rights of the parties to the dispute
                  shall have been finally determined by written agreement among
                  the parties in the dispute or by a Final Order. The Escrow
                  Agent shall deliver the Escrow Funds no later than the second
                  business day after the Escrow Agent has received written
                  notice of any such agreement or Final Order (accompanied by an
                  affidavit that the time for appeal has expired without an
                  appeal having been made) in accordance with the instructions
                  set forth in such agreement or Final Order. The Escrow Agent
                  shall be entitled to assume that no such controversy has
                  arisen unless it has received a written notice that such a
                  controversy has arisen which refers specifically to this
                  Escrow Agreement and identifies by name and address the
                  adverse claimants in the controversy. If a controversy of the
                  type referred to in this subparagraph arises, the Escrow Agent
                  may, in its sole discretion (but shall not be obligated to),
                  commence interpleader or similar actions or proceedings for
                  determination of the controversy;

                           (vi) in the event that the Escrow Agent shall in any
                  instance, after seeking the advice of legal counsel pursuant
                  to the immediately preceding clause, in good faith be
                  uncertain as to its duties or rights hereunder, Escrow Agent
                  shall notify CSBI and Eldorado thereof in writing and after
                  giving such notice it shall be entitled to


                                       4
<PAGE>   5
                  refrain from taking any action hereunder with respect to the
                  matter as to which there is any such uncertainty, and in such
                  event it shall keep safely all funds and investments held in
                  the Escrow until it shall be directed otherwise in a writing
                  signed by CSBI and Eldorado or by a final, nonappealable order
                  of a court of competent jurisdiction; provided, however, in
                  the event that the Escrow Agent has not received such written
                  direction or court order within one hundred eighty (180)
                  calendar days after requesting the same, it shall have the
                  right to interplead CSBI and Eldorado in any court of
                  competent jurisdiction and request that such court determine
                  its rights and duties hereunder;

                           (vii) the Escrow Agent may execute any of its power
                  or responsibilities hereunder and exercise any rights
                  hereunder either directly or by or through agents or attorneys
                  selected with reasonable care; nothing in this Escrow
                  Agreement shall be deemed to impose upon the Escrow Agent any
                  duty to qualify to do business or to act as fiduciary or
                  otherwise in any jurisdiction other than the State of
                  California; and the Escrow Agent shall not be responsible for
                  and shall not be under a duty to examine into or pass upon the
                  validity, binding effect, execution or sufficiency of this
                  Escrow Agreement or of any agreement amendatory or
                  supplemental hereto; and

                           (viii) the Escrow Agent shall not be responsible in
                  any manner whatsoever for any failure or inability of any
                  other party to honor any of the provisions of this Escrow
                  Agreement, the Agreement or any other agreement.

         8. Cooperation and Additional Escrow Instructions. CSBI and Eldorado
shall provide to the Escrow Agent all instruments and documents within their
respective powers to provide that are necessary for the Escrow Agent to perform
its duties and responsibilities hereunder.

         9. Fees and Expenses. The fees of Escrow Agent for its services
hereunder shall be as set forth on Exhibit A; Escrow Agent shall also be
entitled to reimbursement for its out-of-pocket expenses reasonably incurred in
connection with the Escrow, including, without limitation, reasonable attorneys'
fees (all such fees and expenses collectively, the "Escrow Fees"). All of the
Escrow Fees of the Escrow Agent for its services hereunder as and when billed by
the Escrow Agent shall be paid from the earnings on the Escrow Funds, and Escrow
Agent is hereby authorized to withdraw from the Escrow Account such Escrow Fees
as and when due, and to withhold the same from any final distributions such
remaining Escrow Fees. If the Escrow Fees exceed the earnings on the Escrow
Deposit, CSBI shall be responsible therefor and shall pay such excess promptly
upon notification from the Escrow Agent.

         10. Resignation and Removal of the Escrow Agent.

                  (a) The Escrow Agent may resign effective thirty (30) calendar
days following the giving of prior written notice thereof to CSBI and Eldorado.
In addition, the Escrow Agent may be removed and replaced on a date designated
in a written instrument signed by CSBI and Eldorado and delivered to the Escrow
Agent. Notwithstanding the foregoing, no such resignation or removal shall be
effective until a successor escrow agent has acknowledge its appointment as such
as provided in paragraph (c) below. In either event, upon the effective date of
such resignation or removal, the Escrow Agent shall deliver the property
comprising the Escrow to such successor escrow agent,


                                        5
<PAGE>   6
together with such records maintained by the Escrow Agent in connection with its
duties hereunder and other information with respect to the Escrow as such
successor may reasonably request.

                  (b) If a successor escrow agent shall not have acknowledged
its appointment as such as provided in paragraph (c) below, in the case of a
resignation, prior to the expiration of thirty (30) calendar days following the
date of a notice of resignation or, in the case of a removal, on the date
designated for the Escrow Agent's removal, as the case may be, because CSBI and
Eldorado are unable to agree on a successor escrow agent, or for any other
reason, the Escrow Agent may select a successor escrow agent and any such
resulting appointment shall be binding upon all of the parties to this Escrow
Agreement.

                  (c) Upon written acknowledgment by a successor escrow agent
appointed in accordance with the foregoing provisions of this Section 10 of its
agreement to serve as escrow agent hereunder and the receipt of the property
then comprising the Escrow Account, the Escrow Agent shall be fully released and
relieved of all duties, responsibilities and obligations under this Escrow

and such successor escrow agent shall for all purposes hereof thereafter be the
Escrow Agent.

such date as all Escrow Funds have been disbursed in accordance with the terms
hereof either to CSBI or Eldorado.

Commerce Security Bancorp, Inc.
One Pacific Plaza
7777 Center Avenue
Huntington Beach, CA  92647


Ladies and Gentlemen:

       Substantially contemporaneously with the execution of this letter
agreement, Commerce Security Bancorp, Inc. ("CSBI") and Eldorado Bancorp
("Eldorado") are entering into an Agreement and Plan of Merger (the "Merger
Agreement") providing for the acquisition by CSBI of all of the outstanding
capital stock of Eldorado by means of a merger of a direct or indirect
subsidiary of CSBI (the "Merger Sub") with and into Eldorado. The undersigned
persons (each a "Shareholder") understand that CSBI has incurred, and will
continue to incur, substantial expenses in connection with the negotiation and
execution of the Merger Agreement and the subsequent actions necessary to
consummate the Merger. Capitalized terms not defined herein shall have the
meanings ascribed to those terms in the Merger Agreement.

       In consideration of, and as a condition to, CSBI entering into the Merger
Agreement, and in consideration of the expenses incurred and to be incurred by
CSBI in connection therewith, and in consideration of the benefits to be derived
by the undersigned Shareholders by virtue of the consummation of the Merger,
each of the Shareholders severally, and not jointly, agrees with CSBI as
follows:

      1. Each Shareholder represents and warrants that he or she owns as of the
date hereof beneficially, by reason of such Shareholder's power to vote such
Shares at Eldorado's Shareholders' Meeting in connection with the approval of
the Merger Agreement and the Merger, the number of shares ("Shares") of Eldorado
common stock ("Eldorado Common Stock") that is indicated opposite such
Shareholder's name on Appendix A attached hereto.

      2. Effective on the execution and delivery by Eldorado of the Merger
Agreement and continuing until the earlier of (i) the termination of the Merger
Agreement in accordance with its terms and, if applicable, the payment of any
amounts required to be paid by Eldorado by the express terms of the Merger
Agreement in connection with such termination, or (ii) consummation of the
Merger (hereinafter, the "Term of the Merger Agreement"), each Shareholder
agrees to vote, or cause to be voted, at the Eldorado Shareholders' Meeting at
which Merger Agreement and Merger are to be voted on by Eldorado's Shareholders
(or by written consent if such Merger Agreement and Merger are to be acted on by
written consent of Eldorado's Shareholders, in lieu of a meeting of
Shareholders), all of such Shareholder's Shares and any shares of Eldorado
Common Stock the voting power of which is hereafter acquired during the Term of
the Merger Agreement by such Shareholder (a) for the approval of each

Page 2


aspect of the Merger Agreement and the Merger that requires the approval of the
shareholders of Eldorado, (b) against the approval of any Strategic Transaction
Proposal other than the Merger, and (c) in the manner specified in writing by
CSBI from time to time, but in any event not later than the tenth (10th)
business day prior to the scheduled vote, with respect to any other action or
proposal to be voted on by Eldorado's shareholders that would constitute a
breach of the Merger Agreement or otherwise would materially delay or hinder the
ability of Eldorado to consummate of the Merger.

      3. Additionally, effective upon the commencement of the Term of the Merger
Agreement, each Shareholder hereby appoints CSBI and the proper officers of
CSBI, with full power of substitution in the premises, (i) its proxies to vote
all of his or her Shares and (ii) its true and lawful attorneys-in-fact to
execute one or more consents or other instruments from time to time (to the
extent permitted by law and Eldorado's articles of incorporation and by-laws)
during the Term of the Merger Agreement, in each case (x) for approval of the
Merger Agreement and Merger, (y) against any Strategic Transaction Proposal
other than the Merger, and (z) in any manner determined by CSBI with respect to
any other action or proposal that would constitute a breach of the Merger
Agreement or otherwise would materially delay or hinder Eldorado's ability to
consummate the Merger; provided, however, that if CSBI determines that any
matter to be voted on by the shareholders of Eldorado (or on which their consent
is being solicited) would constitute such a breach or have such an effect, then,
not later than the tenth (10th) business day prior to the vote of (or the date
on which written consents are required to be given by) the Eldorado shareholders
with respect thereto, CSBI shall provide written notice to the Shareholder of
such determination and whether and how it intends to vote the proxy given
hereunder with respect thereto. CSBI hereby confirms and agrees that the proxy
and power of attorney granted by each Shareholder to it under this Paragraph 3
does not confer on CSBI any right, power or authority, and that it will not use
or permit the use of any such proxy or power of attorney to call or attempt to
call a special meeting of shareholders of Eldorado for any purpose whatsoever or
to exercise any voting rights or power conferred hereby with respect to any
matter or for any purpose other than to vote on the matters set forth in clause
(x) (y) and (z) hereof. The proxy and power of attorney granted herein shall be
irrevocable during the Term of the Merger Agreement, and shall be deemed to be
coupled with an interest and shall revoke all prior proxies granted by
Shareholder until the conclusion of the Term of the Merger Agreement, at which
time such proxy and power of attorney shall automatically terminate and be of no
further force or effect. Shareholder shall not grant any proxy to any person
which conflicts with the proxy granted herein and any attempt to do so shall be
void.

      4. Each Shareholder agrees that, during the Term of the Merger Agreement,
he or she shall, and shall instruct each of his or her representatives, agents,
advisors and affiliates to, cease and refrain from any activities, discussions,
negotiations or other actions with any parties other than CSBI with respect to
any Strategic Transaction (as defined in the Merger Agreement),

Page 3


except to the extent Eldorado would be permitted to engage in such activities,
discussions, negotiations or other actions pursuant to Section 5.1 or 5.2 of the
Merger Agreement.

      5. Each Shareholder agrees during the Term of the Merger Agreement not to
sell, assign, transfer or otherwise dispose of (including, without limitation,
by the creation of a Lien (as defined in paragraph 7 below)), and shall use its
best efforts not to permit to be sold, assigned, transferred or otherwise
disposed of, any of his or her Shares, except any Shareholder may effectuate (a)
transfers by will or by operation of law (in which case this letter agreement
shall bind the transferee) or to an inter vivos family trust established for the
benefit of the members of his or her immediate family, provided the Shareholder
retains voting control over such Shares, and (b) transfers to any of the other
Shareholders or to any other Person who executes and delivers to CSBI a written
agreement or instrument by which such Person agrees to be bound by and to comply
with this Letter Agreement; provided, however, that no transfer shall be made
under this clause (b) to a Person who is not a director or executive officer of
Eldorado until after the distribution of the Proxy Statement soliciting proxies
with respect to the Merger.

      6. CSBI and each of the Shareholders severally represent, as to himself or
hiself, that he, she or it has the complete and unrestricted power and the
unqualified right to enter into and perform the terms of this Letter Agreement,
subject only to the consensual rights of his or her spouse. CSBI and each of the
Shareholders further severally represents that this letter agreement constitutes
a valid and binding agreement with respect to such party, enforceable against
such party in accordance with its terms (subject, however, to equitable
principles). Each of the Shareholders severally represents that he or she, alone
or together with his or her spouse, has full and unrestricted voting power with
respect to his or her Shares, free and clear of any liens, claims, charges or
other encumbrances and restrictions of any kind whatsoever ("Liens"). EACH OF
THE SHAREHOLDERS FURTHER SEVERALLY REPRESENTS THAT SUCH SHAREHOLDER BEEN
PROVIDED AND HAS REVIEWED THE MERGER AGREEMENT (OR A SUBSTANTIALLY FINAL DRAFT
THEREOF) AND HAS BEEN AFFORDED THE OPPORTUNITY TO DISCUSS THE MATTERS CONTAINED
HEREIN WITH HIS OR HER ADVISORS.

      7. Notwithstanding anything herein to the contrary, the agreements
contained, and the proxies and powers of attorney granted, herein are
irrevocable until and shall remain in full force and effect until the earliest
occurrence of a Termination Event (as hereafter defined), whereupon such
agreements and proxies and powers of attorney shall, without action or notice by
any party hereto, terminate and be of no further force or effect. As used
herein, the sole Termination Events shall consist of (a) the consummation of the
Merger, and (b) the termination of the Merger Agreement in accordance with
Article VII thereof together with, where applicable, the payment of any
Termination Fee or the reimbursement of any Expenses (each as defined in the
Merger Agreement) required to be paid or reimbursed by Eldorado pursuant to
Article VII thereof.

      8. Each of the Shareholders has signed this letter agreement intending to
be bound severally hereby as to his or her agreements and representations and
warranties herein and not to be bound as joint obligors, or with respect to any
agreements or representations or warranties herein of any other Shareholder.
Each Shareholder who has executed this letter agreement shall be bound hereby
whether or not any other Shareholder has also executed this letter agreement.
Each Shareholder who owns any Shares as community property with his or her
spouse represents that such spouse has executed a spousal consent to this letter
agreement.

      9. The parties hereto agree that if any of the provisions of this letter
agreement were not performed in accordance with their specific terms or were
otherwise breached, irreparable damage would occur, no adequate remedy at law
would exist and damages would be difficult to determine, and that the parties
shall (without posting of bond or other security) be entitled to obtain from any
court of competent jurisdiction specific performance of the terms hereof, in
addition to any other remedy at law or in equity. Notwithstanding the foregoing,
CSBI agrees that any shareholder who in fact causes his or her Shares to be
voted, or whose Shares are in fact voted, whether by such Shareholder or by his
or her proxy or attorney-in-fact (including CSBI or its designee as provided in
Section 3 above), in favor of the Merger and otherwise in the manner required by
Section 2 or Section 3 shall have no personal liability to CSBI or any other
person by virtue of this Letter Agreement. 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 to the contrary.

     10. All costs and expenses incurred in connection with this Letter
Agreement and the transactions contemplated hereby shall be paid by the party
incurring such expenses, except as otherwise provided in the Merger Agreement or
in this Section 10. Notwithstanding the foregoing, if either party brings an
action to enforce or to determine the parties' rights under this Letter
Agreement, the prevailing party shall be entitled to recover its reasonable
legal fees and expenses and any related costs incurred by such party (including,
in the case of a Shareholder, by Eldorado on such Shareholder's behalf) in
connection with such action or proceeding.

     11. This letter agreement is to be governed by the laws of the State of
California, without giving effect to the conflicts of laws principles thereof.
If any provision hereof is deemed unenforceable, the enforceability of the other
provisions hereof shall not be affected. This letter agreement may be signed in
any number of counterparts, and each counterpart shall be deemed an original and
all of such counterparts, when taken together, shall constitute one and the same
agreement.

                             STOCK OPTION AGREEMENT


                    THE TRANSFER OF THIS AGREEMENT IS SUBJECT
                     TO CERTAIN PROVISIONS CONTAINED HEREIN
                    AND TO THE RESALE RESTRICTIONS UNDER THE

             EXPIRE ON THE DATE DETERMINED IN ACCORDANCE WITH SECTIONS 2
             AND 14 HEREOF, AND CONTAINS A LIMITATION ON THE AMOUNT WHICH

             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 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

<PAGE>   2
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.

                                        2
<PAGE>   3
             (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

                                        3
<PAGE>   4
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.

       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.

                                        4
<PAGE>   5
       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 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

                                        5
<PAGE>   6
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
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).

                                        6
<PAGE>   7
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 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

                                        7
<PAGE>   8
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 "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

                                        8
<PAGE>   9
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 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.

                                        9

       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, 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

                                       10
<PAGE>   11
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 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

                                       11
<PAGE>   12
       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.

             (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

                                       12
<PAGE>   13
             (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 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

                                       13
<PAGE>   14
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.

TUSTIN, California, December 24, 1996 - Robert P. Keller, Chairman and Chief
