                                                              ____________, 1998

          Dear Shareholder:

         You are cordially invited to attend a Special Meeting (the "CIB
Meeting") of Shareholders of Channel Islands Bank, a California banking
corporation ("CIB"), to be held on _______, ________ __, 1998, at _:__ p.m., at
which you will be asked to consider and vote on a proposal to approve the
principal terms of a proposed merger (the "Merger") pursuant to an amended
Agreement to Merge and Plan of Reorganization, dated as of July 7, 1998 and
amended on September 17, 1998 (the "Agreement"), by and between CIB, Americorp,
a California corporation (the "Americorp") and American Commercial Bank, a
California state-chartered bank ("ACB") and a wholly owned subsidiary of
Americorp, pursuant to which (i) CIB will merge with and into ACB and ACB will
continue as the surviving bank, and (ii) the shareholders of CIB will become
shareholders of Americorp in accordance with the exchange ratio in the Agreement
(the "Merger"). A copy of the Agreement is included with this Joint Proxy
Statement/Prospectus as Appendix A.

         Based on the number of shares of CIB Common Stock outstanding as of the
record date for the CIB Meeting, the shares of Americorp Common Stock to be
issued to CIB shareholders pursuant to the Agreement will represent
approximately 38% of the shares of Americorp Common Stock outstanding following
the Merger. The enclosed Joint Proxy Statement/prospectus more fully describes
the proposed merger and related transactions, including information about CIB,
Americorp and ACB.

         The Board of Directors of CIB has unanimously approved the Agreement
and has determined that the Merger is fair to, and in the best interests of,
holders of CIB Common Stock (the "CIB Shareholders"). In addition, the Findley
Group, as financial advisor to CIB, has delivered its opinion, dated July 7,
1998, to the Board of Directors of CIB that the Exchange Ratio is fair, from a
financial point of view, to the CIB Shareholders. Therefore, the Board of
Directors of CIB unanimously recommends that CIB Shareholders vote "FOR" the
approval of the principal terms of the Merger.

         I urge you to consider carefully these important matters which are
described in the accompanying Joint Proxy Statement/Prospectus. The affirmative
vote of the holders of a majority of the CIB Common Stock entitled to vote at
the CIB Meeting is required for approval of the principal terms of the Merger.
Your failure to vote for approval of the principal terms of the Merger has the
same effect as a vote against the Merger. In order to ensure that your vote is
represented at the CIB Meeting, please indicate your choice on the enclosed
proxy form, date, sign and return it in the enclosed envelope. A prompt response
will be appreciated. If you attend the CIB Meeting you may revoke your proxy and
vote in person if you wish.

         We hope that the Joint Proxy Statement/Prospectus will answer any
questions you may have concerning the Merger and the other items. If you have
any questions concerning the Joint Proxy


                  4
<PAGE>

Statement/Prospectus or the accompanying proxy or if you need any help in
voting your shares, please telephone Mr. Thomas E. Anthony or Mr. Allen
Partridge of CIB at (805) 487-6581.

         YOU SHOULD NOT SEND IN YOUR CERTIFICATES OF CIB COMMON STOCK AT THIS
TIME. YOU WILL RECEIVE INSTRUCTIONS AT A LATER DATE REGARDING THE EXCHANGE OF
YOUR STOCK CERTIFICATES.

         Your interest and participation are appreciated.

                                Sincerely,

                                [SIGNATURE]

                              [AMERICORP LETTERHEAD]

Dear Shareholder:

         You are cordially invited to attend a Special Meeting of the
Shareholders of Americorp to be held on _________ __, 1998, at _________ PM at
the ____________________________________________________, California.

         At this meeting you will be asked to consider and vote upon a proposal
to approve the principal terms of the amended Agreement to Merge and Plan of
Reorganization dated July 7, 1998 and amended on September 17, 1998 ("the
Agreement") by and among Americorp, American Commercial Bank, and Channel
Islands Bank pursuant to which (i) Channel Islands Bank will merge with and into
American Commercial Bank, with American Commercial Bank continuing as the
surviving bank, and (ii) the shareholders of Channel Islands Bank will become
shareholders of Americorp in accordance with the exchange ratio set forth in the
Agreement.

         The enclosed Joint Proxy Statement/Prospectus more fully describes the
proposed merger and related transactions, including information about the
involved entities.

         The Board of Directors of Americorp has carefully considered the terms
and conditions of the Agreement and the proposed merger with Channel Islands
Bank. THE BOARD OF DIRECTORS OF AMERICORP HAS CONCLUDED THAT THE MERGER IS IN
THE BEST INTEREST OF AMERICORP, AMERICAN COMMERCIAL BANK AND HOLDERS OF
AMERICORP COMMON STOCK, AND UNANIMOUSLY RECOMMENDS THAT AMERICORP SHAREHOLDERS
VOTE "FOR" THE APPROVAL OF THE PRINCIPAL TERMS OF THE MERGER. California
Research, the Bank's financial advisor, has delivered to the Board of Directors
of Americorp its opinion that the terms of the exchange ratio are fair, from a
financial point of view, to Americorp's shareholders. A copy of this opinion is
attached as Appendix C to the Joint Proxy Statement/ Prospectus.

         You will also be asked to vote upon a new stock option plan for
Americorp as provided for in the Agreement.

         It is important that your shares be represented and voted at the
Special Meeting, regardless of the number of shares you own and whether or not
you plan to attend the Special Meeting. The affirmative vote of the holders of a
majority of Americorp's common stock entitled to vote at the Special Meeting is
required for approval of the principal terms of the Merger. Your failure to vote
for approval of the


                  6
<PAGE>

principal terms of the Merger has the same effect as a vote against the
Merger. Therefore, we urge you to sign, date and mail the enclosed proxy. If
you decide to attend the Special Meeting and wish to vote in person, you may
withdraw your proxy at that time.

         We hope that the Joint Proxy Statement/ Prospectus will answer any
questions you may have concerning the Merger and the other items. If you have
any further questions please telephone Americorp at (805) 658-6633.

Sincerely,


Allen W. Jue
Chairman of the Board

managements, boards of directors, shareholder groups and businesses are 
combined to create an institution which may provide for, among other things, 
increased synergies, expended products and markets, higher lending limits and 
a reduction of overall overhead costs, including a reduction in duplicate 
positions and employee benefits.  Such mergers may also enhance the liquidity 
of a shareholder's investment and may provide the combined entity with easier 
access to the capital markets.  "Mergers of Equals" provide the same types of 
risk associated with combining any two entities, including (i) the 
disadvantages of being part of a larger entity, including reduced voting 
power and the potential for decreased customer service; (ii) the integration 
of the different corporate cultures of the entities will divert the combined 
entities' management time from other activities and (iii) the proposed 
changes to policies and procedures of the combined entity may not prove to be 
successful to the customers of the combined entity.  "Mergers of Equals" also 
generally provide, among other less favorable aspects, a smaller premium on 
their investment to the non-surviving institutions' shareholders than would 
be anticipated in an actual sale of control, less liquidity to such 
shareholders for their investment than if the non-surviving institution had 
been acquired by a larger acquiror as well as the difficulties associated 
with combining the human resources and cultural differences of two similar 
sized institutions.
    
   
     The Exchange Ratio for the Merger (i.e. the number of shares of 
Americorp Stock into which a share of CIB Stock will be converted) will be 
computed by dividing the CIB Book Value Per Share by the Americorp Book Value 
Per Share. Book Value Per Share for the respective Parties will be determined 
as of the month end preceding the effective time by dividing such Party's 
aggregate book value by its number of shares outstanding on such date. 
"Aggregate Book Value" is a Party's stockholders' equity on such date 
determined in accordance with generally accepted accounting principles except 
(A) as otherwise provided in the Agreement, (B) such amount will not be 
reduced by Merger related expenses, and (C) the allowance for loan and lease 
losses shall be increased by any impairment in the allowance.
    
   
     The exact amount of the Exchange Ratio is dependent, in part, upon 
future results and therefore, presently cannot be determined. By way of 
illustration only, if the respective Book Values Per Share had been 
determined on June 30, 1998 and without any adjustment as permitted in the 
Agreement, Americorp's Book Value Per Share would have been $20.02, CIB's 
Book Value Per Share would have been $13.96 and the Exchange Ratio would have 
been 0.6973 shares of Americorp Stock for each share of CIB Stock. THE ACTUAL 
EXCHANGE RATIO MAY BE HIGHER OR LOWER THAN THE PRECEDING PRO FORMA 
ILLUSTRATION.

                                    SUMMARY

     THE FOLLOWING SUMMARY IS NOT INTENDED TO BE COMPLETE AND IS QUALIFIED IN
ALL RESPECTS BY THE MORE DETAILED INFORMATION INCLUDED IN THIS JOINT PROXY
STATEMENT/PROSPECTUS AND THE APPENDICES HERETO. ALL INFORMATION CONCERNING

MEETING."


                                      16
<PAGE>

     AMERICORP. The Americorp Meeting will be held on December 15,1998 at 
4:00p. m. California time, at 300 S. Mills Road in Ventura, California. 
Americorp shareholders will consider and vote on (i) a proposal to approve 
the principal terms of the Agreement and the transactions contemplated 
thereby, and (ii) a proposal to adopt a new Stock Option Plan in accordance 
with the Agreement. Only holders of record of Americorp Stock at the close of 
business on the Americorp Record Date, _________ __, 1998, will be entitled 
to vote at the Americorp Meeting. At such date, there were outstanding and 
entitled to vote ______ shares of Americorp Stock. Each share of Americorp 
Stock is entitled to one vote. See "THE AMERICORP MEETING."

     THE MERGER

     GENERAL Pursuant to the terms of the Agreement, (i) CIB will merge with
and into ACB and ACB will continue as the surviving bank, and (ii) the
shareholders of CIB will become shareholders of Americorp in accordance with
the exchange ratio set forth in the Agreement, all subject to the terms and
conditions specified in the Agreement. See "THE MERGER."

     EXCHANGE RATIO The issued and outstanding shares of Americorp Stock at
the effective time of the Merger (the "Effective Time") will remain
outstanding (other than shares as to which statutory dissenters' rights are
perfected).

     Other than shares as to which statutory dissenters' rights are
perfected, each share of CIB Stock issued and outstanding immediately prior
to the Effective Time will automatically, without any action on the part of
the holder thereof, be canceled and converted, at the Effective Time, into
the right to receive a number of shares of Americorp Stock as determined by
the exchange ratio established in the Agreement (the "Exchange Ratio").

     The Exchange Ratio (i.e. the number of shares of Americorp Stock into
which a share of CIB Stock will be converted) will be computed by dividing
the CIB Book Value Per Share by the Americorp Book Value Per Share. Book
Value Per Share for the respective Parties will be determined as of the month
end preceding the Effective Time by dividing such Party's aggregate book
value by its number of shares outstanding on such date. "Aggregate Book
Value" is a Party's stockholders' equity on such date determined in
accordance with generally accepted accounting principles except (A) as
otherwise provided in the Agreement, (B) such amount will not be reduced by
Merger related expenses, and (C) the allowance for loan and lease losses
shall be increased by any impairment in the allowance.

     The exact amount of the Exchange Ratio is dependent, in part, upon
future results and therefore, presently cannot be determined. By way of
illustration only, if the respective Book Values Per Share had been
determined on June 30, 1998 and without any adjustment as permitted in the
Agreement, Americorp's Book Value Per Share would have been $20.02, CIB's
Book Value Per Share would have been $13.96 and the Exchange Ratio would have
been 0.6973 shares of Americorp Stock for each share of CIB Stock. THE ACTUAL
EXCHANGE RATIO MAY BE HIGHER OR LOWER THAN THE PRECEDING PRO FORMA
ILLUSTRATION. See "THE MERGER - Exchange Ratio."


                                      17
<PAGE>

     FRACTIONAL SHARES No fractional shares of Americorp Stock will be issued
in the Merger. In lieu thereof, each holder of CIB Stock who would otherwise
be entitled to receive a fractional share will receive an amount in cash
equal to the product (calculated to the nearest ten thousandth) obtained by
multiplying (a) the Americorp Book Value Per Share times (b) the fraction of
the shares of Americorp Stock to which such holder would otherwise be
entitled.

     VOTE REQUIRED FOR THE MERGER

     Approval of the principal terms of Agreement and the transactions
contemplated thereby requires the affirmative vote of not less than a
majority of the votes entitled to be cast by the holders of both CIB Stock
and Americorp Stock at their respective Meetings.

     As of the CIB Record Date, CIB's directors and executive officers and
their affiliates held approximately _____% of the outstanding CIB Stock
entitled to vote at the CIB Meeting. Each of the directors of CIB has agreed
to vote his or her respective shares of CIB Stock in favor of approval of the
principal terms of the Agreement and the transactions contemplated thereby.

     As of the Americorp Record Date, Americorp's directors and executive
officers and their affiliates held approximately _____% of the outstanding
Americorp Stock entitled to vote at the Americorp Meeting. Each of the
directors of Americorp has agreed to vote his or her respective shares of
Americorp Stock in favor of approval of the principal terms of the Agreement
and the transactions contemplated thereby.

     RECOMMENDATION OF CIB'S AND AMERICORP'S BOARDS OF DIRECTORS

     The Boards of Directors of both CIB and Americorp (each by a unanimous
vote) approved the Agreement and the related transactions. The respective
Boards believe the Merger is fair to, and in the best interest of, their
respective institutions and shareholders. Each Board of Directors recommends
to their respective shareholders a vote FOR approval of the principal terms
of the Agreement and the matters contemplated thereby.

     The conclusions of the Parties are based on a number of factors,
including the respective fairness opinions of their investment banking firms,
the expected increase in the market liquidity of a shareholder's investment
and the tax-free nature of the Merger. It is also anticipated that the Merger
will provide the potential for the combined companies to benefit from revenue
enhancement opportunities, including increased ability to serve the
marketplace and cross-sell products and services; increased loan and fee
income by providing higher lending limits; increased opportunities to expand
the loan portfolio; and increased opportunities to create more efficiencies,
thereby reducing overall operating costs to the combined companies. See "THE
MERGER - Background and Reasons for the Merger and Management's
Recommendation - CIB, - Background and Reasons for the Merger and
Management's Recommendation - Americorp."

     CIB FAIRNESS OPINION

     CIB has received a written fairness opinion dated as of July 7, 1998
from the Findley Group ("Findley") that the consideration to be received in

as Appendix B.  CIB has paid Findley a fee of $15,000 in connection with its 
services plus expenses.  See "THE MERGER - CIB Fairness Opinion."
    

     AMERICORP FAIRNESS OPINION
   
     Americorp has received a written fairness opinion dated as of August 12,
1998 from the firm of California Research ("Cal.Research") that the
consideration to be received in the Merger is fair, from a financial point of
view, to the shareholders of Americorp. The Cal.Research opinion is attached
to this Joint Proxy Statement/Prospectus as Appendix C.  Americorp has paid 
Cal. Research a fee of $12,500 in connection with its services plus expenses. 
See "THE MERGER - Americorp Fairness Opinion."
    

     MANAGEMENT AND OPERATIONS OF AMERICORP AND ACB AFTER THE MERGER

     At the Effective Time, CIB will be merged with and into ACB and its
separate corporate existence will terminate.

     The number of directors of Americorp at the Effective Time will be
increased to nine and Allen W. Jue, Robert J. Lagomarsino, Gerald J.
Lukiewski, E. Thomas Martin, Harry L. Maynard (all of whom are from Americorp
and ACB), Michael T. Hribar, Edward F. Paul, Joseph L. Priske and Jacqueline
S. Pruner (all of whom are from CIB) will serve as the Board of Directors of
Americorp and ACB after the Merger until their successors have been chosen
and qualified in accordance with applicable law. Messrs. Jue, Lagomarsino,
Paul and Priske will serve as the executive committee of Americorp and ACB
after the Merger. After the Merger, the principal officers of Americorp and
ACB will be Allen W. Jue (the current chairman of Americorp/ACB), who will
serve as chairman of the board, Joseph L. Priske (the current chairman of
CIB), who will serve as Vice Chairman, and Gerald J. Lukiewski (the current
president and chief executive officer of Americorp/ACB) who will serve as
president and chief executive officer. Thomas E. Anthony (the current Senior
Vice President/Chief Lending Officer of CIB), Allen R. Partridge (the current
Senior Vice President/Chief Financial Officer of CIB) and Mary Martha Stewart
(the current Senior Vice President/Chief Operating Officer of ACB) will serve
as the Chief Lending Officer, Chief Financial Officer and Chief Operating
Officer, respectively, of ACB after the Merger. Joseph L. Priske will also
serve as chairman of ACB's loan committee.

     The Articles of Incorporation and Bylaws of Americorp (except as
otherwise noted above) will continue to govern the business and affairs of
Americorp after the Merger until amended or repealed in accordance with
applicable law. The Articles of Incorporation and Bylaws of ACB will continue
to govern the business and affairs of ACB after the Merger until amended or
repealed in accordance with applicable law except the head office of ACB will
be relocated to the current head office location of CIB. See "THE MERGER -
Management and Operations of Americorp and ACB After the Merger."

   
     Based on the combined bank's assets of approximately $226 million, the 
projected pro forma amount of annual net income has been estimated to be 
$2,235,000 after expenses for the Merger and integration costs, have been 
absorbed.  This net income amount takes into account expected initial cost 
savings of an estimated $637,000 and enhanced revenues of an estimated 
$139,000.  The cost savings are derived from a reduced level of personnel, 
decreased costs of employee benefits per employee and other reduced operational 
expenses on a combined basis.  Revenue enhancements are derived from increased 
lending activity due to the increased lending limits.  Net of taxes, the net 
improvement of net income would be approximately $458,000.  The projected 
proforma earnings per share is estimated to be $2.31 using the number of shares 
outstanding as of June 30, 1998, with CIB's shares outstanding exchanged on a 
 .7000 to 1.000 Exchange Ratio.  This compares to an annualized proforma basic 
earnings per share calculated as of June 30, 1998 of $1.88.
    

   
     This information should be read in conjunction with the historical 
consolidated financial statements of CIB and Americorp, including their 
respective notes thereto, which are included in this Joint Proxy 
Statement/Prospectus, and in conjunction with the combined condensed 
historical selected financial data and other pro forma combined financial 
information appearing elsewhere in this Joint Proxy Statement/Prospectus.  
The cost savings and revenue enhancements reflected above and in this Joint 
Proxy Statement/Prospectus may not be indicative of the results that may be 
achieved in the future.  Assuming consummation of the Merger, the actual cost 
savings and revenue enhancement that may be realized in the Merger may 
differ, perhaps significantly, from the amounts reflected above and in this 
Joint Proxy Statement/Prospectus due to a variety of factors, including 
expected growth of the combined bank.  See "UNAUDITED PRO FORMA COMBINED 
FINANCIAL STATEMENT."
    

         EFFECTIVE TIME OF THE MERGER


                                      19
<PAGE>

     The Effective Time shall occur on the day that the Agreement of Merger
(which is Exhibit A to the Agreement) is filed with the California Department
of Financial Institutions ("DFI") after having been previously filed with the
California Secretary of State ("Secretary") with the DFI's approval endorsed
thereon in accordance with the provisions of the California Financial Code.
The Effective Time shall occur following the last to occur of (i) receipt of
all necessary regulatory approvals with the expiration of any applicable
regulatory waiting periods and (ii) satisfaction of the other conditions
precedent set forth in the Agreement. See "THE MERGER - Conditions to the
Merger."

     It is anticipated that the Effective Time will occur sometime during the
fourth quarter of 1998 or early in 1999. In no event shall the Effective Time
be later than March 31, 1999 unless a later date is agreed to by the Parties.

     CONDITIONS TO THE MERGER

     The respective obligations of CIB and Americorp to consummate the Merger
are subject to a number of conditions precedent, including, among others, (i)
the receipt of required regulatory approvals, (ii) the approval by the
shareholders of all Parties of the principal terms of the Agreement and the
transaction contemplated thereby by the vote required under applicable law at
the respective Meetings, (iii) the receipt of fairness opinions by the
Parties that the terms of the Merger are fair from a financial point of view,

     REGULATORY APPROVALS

     The consummation of the Merger is subject to various conditions,
including, among others, receipt of the prior approvals of the DFI and the
Federal Deposit Insurance Corporation (the "FDIC").

     The Agreement provides that the obligations of the Parties to consummate
the Merger are conditioned upon all regulatory approvals having been granted
by March 31, 1999 without the imposition of conditions which, in the opinion
of Americorp would materially adversely effect the financial condition or
operations of any Party or otherwise would be burdensome.

     Applications for regulatory review and approval of the Merger and the
related transactions have been filed. There can be no assurance that the DFI
and the FDIC will approve or take other required action with respect to the
Merger and the related transactions or as to the date of such approvals or
action. See "THE MERGER - Regulatory Approvals."

     WAIVER AND AMENDMENT

<PAGE>

agreement of the Parties' respective Boards of Directors without action by
their respective shareholders to the extent permitted by law. See "THE MERGER
- - Amendment and Waiver."

     TERMINATION

     The Agreement may be terminated at any time prior to the Effective Time
(i) by mutual consent of CIB and Americorp in writing; (ii) by CIB or
Americorp if any material breach or default by the other Party is not cured
within 20 business days after notice thereof; (iii) by CIB or Americorp if
any governmental or regulatory consent is not obtained by March 31, 1999 or
if any governmental or regulatory authority denies or refuses to grant any
approval, consent or authorization required to be obtained to consummate the
transactions contemplated by the Agreement unless, within 20 business days
after such denial or refusal, all parties agree to resubmit the application
to the regulatory authority that has denied or refused to grant the approval,
consent or qualification requested; (iv) by Americorp if any of the
conditions to its performance of the Agreement shall not have been met, or by
CIB if any of the conditions to its performance of the Agreement shall not
have been met, by March 31, 1999, or such earlier time as it becomes apparent
that such conditions shall not be met; or (v) if a Party shall have failed to
act or refrained from doing any act, in certain circumstances, relating to a
Competing Transaction (as hereinafter defined). See "THE MERGER -
Termination."

     INTERESTS OF CERTAIN PERSONS IN THE MERGER

     As a condition to the Merger, each of the directors of the respective
Parties has entered into an agreement whereby each has agreed to (i) vote his
or her shares of Stock in favor of approving the principal terms of the
Agreement and the transactions contemplated thereby, (ii) recommend, subject
to his or her fiduciary duty, to the Party's shareholders to vote in favor of
the Agreement, (iii) not dispose, subject to certain exceptions, of his or
her shares of Stock, and (iv) cooperate fully with the other Parties in
connection with the Merger. See "THE MERGER - Interests of Certain Persons in
the Merger."

     Messrs. Hribar, Paul and Priske and Ms. Pruner will be added as
directors of Americorp and ACB at the Effective Time. Messrs. Paul and Priske
will also serve on the executive committee of Americorp and ACB. Mr. Priske,
the current Chairman of CIB, will be elected as Vice Chairman of Americorp
and ACB and will be chairman of ACB's loan committee.

     The officers and employees of CIB at the Effective Time will become
officers and employees of ACB subject to the policies of ACB, will be
entitled to participate in all employee benefits and benefit programs of ACB
on the same basis as similarly situated employees of ACB and will be credited
for eligibility, participation and vesting purposes with their respective
years of past service with CIB.

     Pursuant to the Agreement, a committee has been established to
determine, among other things, a personnel, salary and benefits structure for
ACB after the Merger and to fix the amount of severance to be paid to
officers and employees of the parties displaced by the Merger. The committee
is composed of


                                      21


<PAGE>

Gerald J. Lukiewski (on behalf of Americorp) and Joseph L. Priske and
Jacqueline Pruner (on behalf of CIB). The amount of severance benefits has
not yet been determined by the committee.

     ACB has also agreed to honor certain employment agreements for CIB's
Senior Lending Officer and Chief Financial Officer. For a description of such
agreements, see "BUSINESS OF CIB - Executive Compensation." Messrs. Anthony
and Partridge will become the Chief Lending Officer and the Chief Financial
Officer of ACB after the Merger.

     In connection with the three current directors of CIB and the two
current directors of Americorp who will resign at the time of the Merger, it
is anticipated that ACB will enter into consulting agreements with such
persons in order for them to continue to provide services and guidance to
Americorp and ACB after the Merger. It is anticipated that Catherine S. Wood
and Lincoln E. Cryne, (directors of Americorp and ACB) will receive aggregate
payments of $33,000 and $68,000 respectively, pursuant to their consulting
agreements and that Fred G. Buenger, William Burke and Glenn C. Farr
(directors of CIB) will receive $33,000, $33,000 and $4,500, respectively,
pursuant to their consulting agreements. See "THE MERGER - Interests of
Certain Persons in the Merger."

     Subject to the receipt of any required consents, a new stock option plan
will be adopted by Americorp in order for each person who is an officer or
employee of CIB and who will continue with ACB after the Merger, and for each
director of CIB, who does not exercise his stock option to have the right to
receive a substitute stock option from Americorp on a fully vested basis.

     CIB's directors' and officers' liability insurance will have its
discovery period extended for 36 months with respect to all matters arising
from facts or events which occurred before the Effective Time for which CIB
would have had an obligation to indemnify its directors and officers.

     ADDITIONAL AGREEMENTS

     In addition to the directors agreements described in "Interests of
Certain Persons in the Merger," the directors and certain other affiliates of
each of the Parties have entered into agreements restricting such persons'
ability to sell shares of Stock which such person has acquired or may acquire
in connection with the Merger except in accordance with such agreements.

   
     FEDERAL INCOME TAX CONSEQUENCES

     The Parties have received an opinion from Vavrinek Trine Day & Co.
("Vavrinek") that the Merger will qualify for non-recognition
of gain or loss so that none of CIB, Americorp or ACB will recognize gain or
loss for federal income tax purposes as a result of the Merger. Such opinion
also concludes that the shareholders of CIB and Americorp will not recognize
gain or loss in the Merger except to the extent of any cash received in lieu
of fractional shares by CIB shareholders, or, in the case of shareholders of
CIB and Americorp, to the extent of any cash received pursuant to the
exercise of statutory dissenters' rights. For a more complete description of
the federal income tax consequences of the Merger,
    

                                      22

<PAGE>

   
see "THE MERGER - Federal Income Tax Consequences." DUE TO THE
INDIVIDUAL NATURE OF THE TAX CONSEQUENCES OF THE MERGER, IT IS RECOMMENDED
THAT CIB AND AMERICORP SHAREHOLDERS CONSULT THEIR OWN TAX ADVISORS CONCERNING
THE TAX CONSEQUENCES OF THE MERGER.
    

     ACCOUNTING TREATMENT

     The Parties anticipate that the Merger will be treated as a pooling of
interests for accounting purposes. Prior to the Effective Time and as a
condition precedent to the closing, the respective accounting firms of the
Parties will confirm in writing the accounting treatment of the Merger as a
pooling of interest. See "THE MERGER - Accounting Treatment."

     DISSENTERS' RIGHTS

     Pursuant to the provisions of the California Financial Code,
shareholders of CIB and Americorp will be entitled to exercise dissenters'
rights in connection with the Merger.

     A holder of stock who, not later than 30 days after the date on which
the Party of which he or she is a shareholder delivers the notice of approval
of the Merger by the Party's shareholders, delivers to such Party a written
demand for dissenters' rights, who does not vote in favor of the approval of
the principal terms of the Agreement and who complies with all other
applicable requirements of Chapter 13 of the California General Corporation
Law, will have the right to receive payment in cash of the "fair market
value" of such holder's shares of Stock. The Americorp Board of Directors has
determined that the "fair market value" of one share of Americorp Stock for
this purpose is $32.00, which was the closing bid price for Americorp Stock
on July 6, 1998, the day before the public announcement of the Merger. Based
upon the opinion of the Findley Group, the CIB Board of Directors has
determined that the "fair market value" of one share of CIB Stock for this
purpose is $19.50. See "THE MERGER - Dissenting Shareholders' Rights" for a
further discussion of dissenters' rights. The Chapter 13 of the California
General Corporation Law is included in Appendix D to his Joint Proxy
Statement/Prospectus.

     EXCHANGE OF STOCK CERTIFICATES

     As soon as practicable after the Effective Time, shareholders of record
of outstanding shares of CIB Stock will receive by mail a letter of
transmittal which is to be used to exchange their CIB Stock for a new
certificate representing the appropriate number of shares of Americorp Stock,
together with checks for payment of cash in lieu of fractional shares. No
dividends or other distributions that are declared on Americorp Stock will be
paid to persons otherwise entitled to receive the same until the old
certificates have been surrendered in exchange for new certificates, but upon
such surrender, such dividends or other distributions, from and after the
Effective Time, will be paid to such persons in accordance with the terms of
Americorp Stock. No interest will be paid to the CIB shareholders on the cash
or the value of the Americorp Stock into which their shares of CIB Stock will
be exchanged. See "THE MERGER - Exchange Procedures."


                                      23

     CIB SHAREHOLDERS SHOULD NOT SEND IN THEIR STOCK CERTIFICATES UNTIL THEY
RECEIVE THE LETTER OF TRANSMITTAL FORM AND INSTRUCTIONS.

STATEMENT OF INCOME ANALYSIS

INCOME SUMMARY

        Americorp reported net earnings of $649,000 or $1.09 basic income per 
share for the first nine months of 1998.  This represents a 16.0% decrease in 
earnings over the same period during 1997 when net earnings were $773,000 or 
$1.34 basic income per share.

        Americorp also reported net earnings of $88,000 or $0.15 basic income 
per share for the quarter ended September 30, 1998.  This represents a 66.4% 
decrease in earnings over the same period during 1997 when net earnings were 
$262,000 or $0.45 basic income per share.

        Annualized return on assets for the nine months ended September 30, 
1998 was 0.64% compared with 0.81% for the same period during 1997.  
Annualized return on equity for the nine months ended 1998 was 7.62% compared 
with 9.84% for the same period during 1997.

        Annualized return on assets for the quarter ended September 30, 1998 
was 0.25% compared with 0.83% for the same period during 1997.  Annualized 
return on equity for the quarter ended September 30, 1998  was 2.96% compared 
with 9.78% for the same period during 1997.

        Quarterly cash dividends of $0.21 per share were paid in January, 
April, and July, 1998 and 1997.

        In July of 1998, the Directors of ACB approved the termination of the
Directors Deferred Compensation Plan.  On the date of the termination, all
participating Directors became 100% vested in there retirement benefits.  The
termination of the plan resulted in the incurring of additional liabilities of
$175,600.  $95,260 is required to vest the participating Directors 100% in
their benefits and $80,400 was approved for additional benefits to cover the
estimated taxes the Directors will pay on the early termination of the Plan.
The termination of the Plan requires the additional liabilities to be recorded
and expensed over the final six months of the calendar year 1998.  $87,600 was
recognized during the quarter ended September 30, 1998.

        In conjunction with the Agreement, Americorp has incurred and posted 
legal and professional fee expenses specifically related to the merger.  As 
of September 30, 1998, a total of $106,000 have been recorded as a reduction 
to income.

NET INTEREST INCOME

        Net interest income is the amount by which the interest and 
amortization of fees generated from loans and other earning assets exceeds 
the cost of funding those assets, usually deposit account interest expense.  
Net interest income depends on the difference (the "interest rate spread") 
between gross interest and fees earned on the loans and investment portfolios 
and the interest rates paid on deposits and borrowings.  Net interest income 
was $5,679,000 for the nine months ended September 30, 1998, compared to 
$5,154,000 for the nine months ended September 30, 1997. Net interest income 
was $1,868,000 for the quarter ended September 30, 1998, compared to 
$1,791,000 for the quarter ended September 30, 1997.

        Interest income grew $669,000 or 9.3% for nine months ended September 
30, 1998 compared to the nine months ended September 30, 1997.  The increased 
interest income between these two periods is comprised of two key elements, 
interest on loans and investments.  Average outstanding loans for the nine 
months ended September 30, 1998 and 1997, were $83,002,000 and $72,996,000, 
respectively.  This represents a $10,006,000 average increase.  The yield on 
loans for this period decreased from 10.07% to 9.94% or (0.13%).  The 
increase in average outstanding balances and decrease in yield resulted in an 
overall increase in loan interest income totaling $672,000.  Average 
outstanding investments for the nine months ended September 30, 1998 and 
1997, were $33,582,000 and $34,236,000, respectively.  This represents a 
$(654,000) average decrease.  The yield on investments for this period 
decreased from 5.70% to 5.52% or (0.18%).  The decrease in average 
outstanding balance and decrease in yield resulted in an overall decrease in 
investment interest income totaling $(74,000).  Total fees on loans increased 
during interim 1998 by $71,000.

        Interest income grew $132,000 or 5.3% for the quarter ended September 
30, 1998 compared to the quarter ended September 30, 1997.  The increased 
interest income between these two periods is comprised of two key elements, 
interest on loans and investments.  Average outstanding loans for quarter 
ended September 30, 1998 and 1997, were $83,436,000 and $77,389,000, 
respectively.  This represents a $6,047,000 average increase.  The yield on 
loans for this period decreased from 10.28% to 9.73% or (0.55%).  The 
increase in average outstanding balances and decrease in yield resulted in an 
overall increase in loan interest income totaling $41,000.  Average 
outstanding investments for the quarter ended September 30, 1998 and 1997, 
were $37,802,000 and $31,744,000, respectively. This represents a $6,058,000 
average increase.  The yield on investments for this period increased from 
5.39% to 5.45% or 0.06%.  The increase in average outstanding balance and 
increase in yield resulted in an overall increase in investment interest 
income totaling $88,000.  Total fees on loans increased by $3,000 comparing 
the 3rd quarter of 1998 to 1997.

        Interest expense increased $144,000 or 7.1% for nine months ended 
September 30, 1998 compared to the nine months ended September 30, 1997.  
Average outstanding interest bearing deposits for the nine months ended 
September 30, 1998 and 1997 were $87,213,000 and $82,994,000, respectively.  
This represents a $4,219,000 average increase.  The cost on these deposits 
for this period increased from 3.26% to 3.32% or 0.06%.  The increase in 
average outstanding balances and increase in cost resulted in an overall 
increase to interest expense for this period.

        Interest expense increased $55,000 or 7.9% for the quarter ended 
September 30, 1998 compared to the quarter ended September 30, 1997.  Average 
outstanding interest bearing deposits for the quarter ended September 30, 
1998 and 1997 were $90,269,000 and $83,868,000, respectively.  This 
represents a $6,401,000 average increase.  The cost on these deposits for 
both periods was approximately 3.31%.  The increase in average outstanding 
balances therefore resulted in an overall increase to interest expense for 
this period.

        On March 26, 1997 the prime rate changed from 8.25% to 8.50% and 
remained steady through September 30, 1998.

        For the nine months ended September 30, 1998 and 1997 the average 
loan-to-deposit ratio increased to 68.4% compared to 64.8%.  As of September 
30, 1998, the loan-to-deposit ratio was 64.9%.

        For the quarter ended September 30, 1998 and 1997 the average 
loan-to-deposit ratio decreased to 66.3% compared to 67.2%.

PROVISION FOR LOAN LOSSES
    

<PAGE>
   
        Americorp did not make a contribution to the allowance for loan 
losses in the third quarter of 1998.  Management continues to believe that 
the allowance, which stands at 1.29% of total loans at September 30, 1998, is 
adequate to cover future losses.  In September 1998, there were a number of 
distinct and controllable factors that precluded the need to increase the 
allowance for loan losses.  Included in non-accrual loans at September 30, 
1998, are loans totaling $956,000 that are in the process of being renewed or 
paid off from other lenders and are secured by real property assets that 
provide adequate collateralization.

        Changes in the allowance for loan losses for the quarters ended 
September 30, 1998 and 1997 are as follows:

NON INTEREST INCOME
    
   
Non Interest Income represents deposit account services charges and other
types of non-loan related fee income.  Non-interest income for the quarter
ended September 30, 1998 totaled $387,000 compared to $357,000 for the same
period during 1997.  This represents an increase of $30,000.  The major
contributing factor to this difference is an overall increase continues to be
Real Estate brokering fees.
    
   
NON INTEREST EXPENSE
    
   
        Non Interest Expenses represent salaries, occupancy expenses, 
professional expenses, outside services and other miscellaneous expenses 
necessary to conduct business.  Non-interest expense for the quarter ended 
September 30, 1998 totaled $2,085,000 compared to $1,753,000 for the same 
period during 1997. This represents an increase of $332,000.  The major 
contributing factors to this difference are an overall increase in salaries 
of $94,000 due to the changes that have taken place in upper management and 
full operations of the Camarillo branch.  The additional accrual for the 
aforementioned termination of the Director Deferred Compensation Plan totaled 
$87,800.  Merger related expenses total $106,000.  Occupancy expenses are up 
$20,000 due to the opening of the new branch and a significant increase in 
the Common Area Maintenance charges for one branch and COL increases for 
another.  Other smaller items make up the balance of the remaining 
differences.
    
   
BALANCE SHEET ANALYSIS
    
   
        Total assets at September 30, 1998 totaled $142,857,000, up 8.6% from 
the same period during 1997.  Deposits have increased during this time period 
by $9,890,000 or 8.4%.  Other Assets decreased by $2,707,000.  This decrease 
is primarily due to the dissolution of the bank's investments in certain 
partnerships.  These monies along with regular earnings have been used to 
fund the increase in loans of $4,546,000 and securities and Fed Funds  of 
$9,646,000.
    
   
        During the third quarter of 1998, total assets increased by

    PERFORMANCE SUMMARY.   CIB's net income for the first nine months of 1998 
was $540,000, an increase of 8.3% over the like period in 1997.  These earnings 
represented an annualized return on average assets of .82% for the nine month 
period ending September 30, 1998, down from the .85% return for the like period 
in 1997.  Capital increased from $6,101,000 as of September 30, 1997 to 
$8,013,000 as of September 30, 1998 yielding a 31.3% increase.  This increase 
is due to both the retention of earnings and exercise of stock options.  This 
rate of capital growth exceeded the growth rate of earnings.  As a result, the 
decline in the annualized return on average equity is greater than the decline 
in the return on average assets.   The return on average equity declined from 
11.3% to 9.8% for September 30, 1997 as compared to September 30, 1998.  Net 
income per share was $1.08 (basic) for the nine month period ending September 
30, 1997 compared to $0.97 (basic) for the like period in 1998.
    
   
    Net income increased by $41,000 or 8.2% for the nine month period ending 
September 30, 1998 compared to the like period for 1997.  Increases in CIB's 
net interest income (up $364,000) and non-interest income sources (up $163,000) 
were more than offset by increases in non-interest expenses of $590,000.  This 
leaves a reduced amount of provision for loan losses to account for the over 
all increase in net income.  The amount of provision for loan losses for the 
nine month period ending September 30, 1998 was $58,000 as compared to the 
$180,000 for the like period for 1997.
    
   
    NET INTEREST INCOME.   CIB's annualized yield on interest earning assets 
was 8.88% for the first nine months of 1998 compared to 8.90% for the like 
period of 1997.  Annualized interest expense as a percent of earning assets was 
2.60% and 2.63% for 1997 and 1998 respectively for the  first nine months.  As 
a result of these two factors net interest income expressed as a percent of 
earning assets declined slightly from 6.31% to 6.25%.
    
   
    PROVISION AND ALLOWANCE FOR LOAN LOSSES.   The contribution or provision 
to the allowance for loan losses for the first nine months of 1998 was $58,000 
compared to $180,000 for the like period in 1997.  The balance in the allowance 
for loan losses stood at $895,000 and $774,000 for September 30, 1998 and 
September 30, 1997, respectively.  The allowance as a percent of loans was 
1.51% and 1.53% for those same periods.  Non-performing assets, made up of 
nonaccruing loans, accruing loans 90 days or more past due and Other Real 
Estate Owned ("OREO"), totaled $535,000 as of September 30, 1997.  This total 
declined to $47,000 as of September 30, 1998, with zero balances in the 
nonaccrual and OREO categories..  Management continues to believe that the 
allowance is adequate to cover future losses.
    
   
    NONINTEREST INCOME.  Noninterest income for the first nine months of 1998 
was $725,000, up $163,000 from the like period for 1997, or 29.0%.  The primary 
reasons for the increase were increased deposit service charge collections (an 
$80,000 increase) and gain on sale of OREO (an $88,000 increase).  
    
   
    NONINTEREST EXPENSE.  Noninterest expense for the first nine months of 
1998 was $3,718,000, up $590,000 from the like period for 1997, or 18.9%.  The 
primary reasons for this increase were increased salary and benefit expenses (a 
$269,000 increase), increased occupancy , furniture and equipment expenses (a 
$116,000 increase) and increased legal and professional services expenses (a 
$169,000 increase).  As of September 30, 1998, a total of $91,000 expenses in 
the legal and professional services category have been incurred related to the 
proposed merger.
    
   
    BALANCE SHEET.   Total assets at September 30, 1998 totaled $93,761,000, 
up 15% from September 30, 1997 assets of $81,546,000.  There were corresponding 
increases in net loans and investments.  Net loans increased 18.6% when 
comparing the nine month periods ending September 30, 1997 and 1998 and 
Investments including Federal Funds Sold grew 20% for the same periods.
    
   
    Total asset growth was funded through a $10,199,000 increase in 
deposits and a $1,912,000 increase in equity when comparing the first nine 
month periods for 1998 and 1997.
    
   
    CIB's loan to deposit ratio of 68.3% for September 30, 1998 is up from the 
66.0% ratio for September 30, 1997.
    
   
    CAPITAL RESOURCES.   Total stockholders' equity increased from $6,101,000 
at September 31, 1997 to $8,013,000 at September 30, 1998.  Net income over 
this 12 month time period of $842,000 less cash dividends of $99,000 accounted 
for $743,000 of the increase.  The remainder is primarily made up of the 
$1,104,000 value of optioned shares exercised along with their related tax 
benefits. 
    
   
    The leverage ratio of equity to average assets increased from 7.8% as of 
September 30, 1997 to 9.1% as of September 30, 1998.  Similarly, CIB's ratios 
of Tier One Capital and Total Capital to risk-adjusted assets also increased.  
The Tier One ratio increased from 10.2% one year earlier to 10.8% at September 
30, 1998.  The Total Risked Based Capital ratio increased from 11.5% to 12.0% 
for the same periods.
    
   
    LIQUIDITY.  Management is not aware of any future capital expenditures or 
other significant demands or commitments that would significantly impact 
liquidity.

                               RISK FACTORS

     IN DECIDING HOW TO VOTE THEIR SHARES AT THE MEETINGS, HOLDERS OF SHARES
OF CIB STOCK AND HOLDERS OF SHARES OF AMERICORP STOCK SHOULD CAREFULLY CONSIDER
THE FOLLOWING FACTORS, IN ADDITION TO THE INFORMATION AND OTHER MATTERS SET
FORTH IN THIS JOINT PROXY STATEMENT/PROSPECTUS.

     FORWARD LOOKING STATEMENTS MAY NOT PROVE ACCURATE

   
     Certain statements contained in this Joint Proxy Statement/Prospectus, 
including, without limitation, statements containing the words "believes," 
"anticipates," "intends," "expects" and words of similar import, constitute 
"forward-looking statements." Such forward looking statements involve known 
and unknown risks, uncertainties and other factors that may cause the actual 
results, performance or achievements of CIB or Americorp to be materially 
different from any future results, performance or achievements expressed or 
implied by such forward-looking statements. Such factors include, among 
others, the following: general economic and business conditions in those 
areas in which CIB or Americorp operate; demographic changes; competition; 
fluctuations in interest rates; changes in business strategy or development 
plans; changes in governmental regulation; credit quality; the availability 
of capital to fund the expansion of CIB's or Americorp's business; and other 
factors referenced in this Joint Proxy Statement/Prospectus, including, 
without limitation, under the captions "SUMMARY," "RISK FACTORS" "BUSINESS OF 
CIB," and "BUSINESS OF AMERICORP." Given these uncertainties, shareholders 
are cautioned not to place undue reliance on such forward-looking statements. 
CIB and Americorp disclaim any obligation to update any such factors or to 
publicly announce the results of any revisions to any of the forward-looking 
statements contained herein to reflect future events or developments.
    

     RISK FACTORS RELATING TO THE MERGER

   
     INABILITY TO INTEGRATE OPERATIONS OR TO ACHIEVE REVENUE ENHANCEMENT AND 
COST SAVINGS. The earnings, financial condition and prospects of ACB and 
Americorp after the Merger will depend in part on ACB's ability to 
successfully integrate the operations and management of CIB and to continue 
to implement its own business plan. There can be no assurance that ACB will 
be able to effectively and profitably integrate the operations and management 
of CIB, or that ACB will be able to continue to profitably implement its own 
business plan. In addition, there can be no assurance that ACB will be able 
to fully realize the potential revenue enhancement expected as a result of 
the Merger. Further, although the CIB Board and the Americorp Board do 
anticipate cost savings as a result of the Merger to be significant (as 
compared to potential revenue enhancement as a result of the Merger), there 
can be no assurance that ACB will be able to fully realize any of the 
potential cost savings expected. Finally, there can be no assurance that any 
cost savings which are realized will not be offset by losses in revenues or 
other charges to earnings.
    

                                       32

<PAGE>

   
     ADVERSE DIFFERENCE IN ANTICIPATED PERFORMANCE OF COMBINED LOAN 
PORTFOLIOS. ACB's performance and prospects after the Merger also will be 
dependent to a significant extent on the performance of the combined loan 
portfolios of ACB and CIB and ultimately on the financial condition of ACB's 
and CIB's borrowers and other customers. The existing loan portfolios of ACB 
and CIB differ to some extent in the types of borrowers, industries and 
credits represented. In addition, there are differences in the documentation, 
classifications, credit ratings and management of the portfolios. As a 
result, ACB's overall loan portfolio after the Merger will have a different 
risk profile than the loan portfolio of either ACB or CIB before the Merger. 
The performance of the combined loan portfolio will be adversely affected if 
any of such factors is worse than currently anticipated. In addition, to the 
extent that present customers are not retained by the surviving bank or 
additional expenses are incurred in retaining them, there could be adverse 
effects on future results of operations of ACB following the Merger. 
Realization of improvement in profitability is dependent, in part, on the 
extent to which the revenues of Americorp and ACB are maintained and enhanced.
    
   
     UNCERTAINTY OF MARKET PRICE OF AMERICORP STOCK AFTER THE MERGER. The 
number of shares of Americorp Stock which will be issued to CIB shareholders 
in the Merger is determined by the respective book values per share of 
Americorp Stock and CIB Stock. No assurance can be given how the market price 
of Americorp Stock on or after consummation of the Merger will react to the 
Exchange Ratio.
    
   

     LIMITED MARKET FOR AMERICORP STOCK AND FAILURE OF AN ACTIVE MARKET TO 
DEVELOP. There is currently only a limited trading market for the CIB and 
Americorp Stocks. While an application for listing Americorp Stock on Nasdaq 
will be considered during the first year of combined operations, there can be 
no assurance that such an application will be filed or the Americorp Stock 
actually listed on Nasdaq. Additionally, there can be no assurance that an 
active trading market for Americorp Stock will develop as a result of the 
Merger or otherwise, or if developed, will continue, or that shareholders of 
Americorp will be able to resell their securities or otherwise liquidate 
their investment without considerable delay, if at all, or considerable 
impact on the sale's price.

    
   
     RISK OF DIVIDEND POLICY CHANGE AND DEPENDENCY ON VARIOUS FACTORS. 
Americorp has paid 59 consecutive quarterly cash dividends to its 
shareholders. Americorp is currently paying quarterly cash dividends of $0.21 
per share. The dividend policy of Americorp is not expected to be changed as 
a result of the Merger; however, no assurances can be given that such policy 
may not change. Moreover, declarations or payments of dividends by the Board 
of Directors of Americorp after the Merger will depend upon a number of 
factors, including capital requirements, regulatory limitations, Americorp's 
and ACB's financial condition and results of operations, tax considerations 
and general economic conditions. No assurance can be given that any dividends 
will be declared or, if declared, what the amount of dividends or their type 
(cash, stock or both) will be or whether such dividends, once declared, will 
continue.
    

     YEAR 2000 RISKS AND PREPAREDNESS. Many existing computer programs use
only two digits to identify a year in a data field. These programs were
designed and developed without considering the impact of the upcoming change
in the century. If not corrected, many computer applications could fail or
create erroneous results by or at the Year 2000 or possibly earlier. The Year
2000 issue affects Americorp in that the financial services business is
highly dependent on computer applications in a variety

                                       33

<PAGE>
   
of ways, including the following (i) Americorp relies on computer systems in
almost all aspects of its business, including the processing of deposits,
loans and other services and products offered to customers, the failure of
which in connection with the Year 2000 could cause systemic disruptions and
failures in the products and services offered by Americorp, (ii) other banks,
clearing houses and vendors whose products and services Americorp uses are at
risk of systemic disruptions and potential failures in the event that such
entities have not adequately addressed their Year 2000 issues prior to the
Year 2000, (iii) the creditworthiness of borrowers of Americorp might be
diminished by significant disruptions of their business as a result of their
own or others' failure to address adequately the Year 2000 issues prior to
the Year 2000, and (iv) federal banking agencies have issued interagency
guidance on the business-wide risk posed to financial institutions by the
year 2000 problem pursuant to which the federal banking agencies may take
supervisory action against financial institutions that fail to address
appropriately Year 2000 issues prior to the Year 2000, including formal and
informal enforcement actions, denial of applications to the federal banking
agencies, civil money penalties and a reduction in the management component
rating of the institution's composite rating. 
    
     In order to address the Year 2000 issues facing Americorp, Americorp
Management has initiated a program to prepare Americorp's computer systems
and applications for the Year 2000 (the "Year 2000 Plan"). The primary focus
of the Year 2000 Plan is to convert to the target systems identified and
believed to be Year 2000 compliant. Americorp expects to incur internal staff
costs as well as consulting and other expenses related to infrastructure and
facilities enhancements necessary to prepare for conversion and Year 2000
system preparations, testing and conversion of primary system applications
and hardware is expected to cost approximately $100,000, to be expended
during fiscal years 1998 and 1999.

     As a part of the Year 2000 Plan, Americorp is not only undertaking the
infrastructure and facilities enhancement and testing necessary to ensure
that Americorp is adequately prepared for the Year 2000, but Americorp is
also communicating with its vendors upon whose services Americorp relies to
ensure Year 2000 compliance. Pursuant to the Year 2000 Plan, Americorp
expects to substantially complete testing of its mission-critical systems and
the computer-related interactive vendor systems by December 31, 1998 and to
complete all testing by June 1999. In addition, as part of the credit review
process, Americorp is communicating with its major borrowers in an effort to
ensure that such borrowers have taken appropriate steps to address their Year
2000 issues and will not be materially affected by any Year 2000 problems.
Americorp is communicating with its deposit customers as well. Americorp is
also preparing contingency plans to protect Americorp in the event that
Americorp is unable to attain Year 2000 compliance in certain applications
according to the Year 2000 Plan.

   

     Americorp has established a working committee comprised of Senior and 
Middle Management to plan for and monitor Americorp's compliance with Year 
2000 ("Y2K") issues.  This committee has developed a comprehensive policy 
setting forth priorities and a timetable for ACB to follow in this process. 
    
   
     Americorp has developed a contingency plan that identifies the mission 
critical processes and service providers.  An alternative provider or process 
has been identified for each mission critical vendor.  In addition, on the 
assumption that the original or alternative process fails at the point of 
processing in the Year 2000, contingency plans are being designed that will 
provide minimum levels of service or outputs until the failed system can be 
repaired or replaced.  Most of these contingency plans are manual effort 
systems.  Test results to-date indicate that the original system for each 
mission critical system should meet the demands of processing in the Year 
2000. As a reasonable worst case, the manual systems designed should provide 
the minimum levels of service for the time required to repair or replace 
failed systems.  However, in the case of failure, the ultimate impact on 
financial operations is not known, nor is it known what impact a regional or 
nationwide power failure or communications breakdown would have on the 
financial performance of Americorp.  In the first three weeks of November, 
two full-time dedicated employee/consultant resources have been jointly 
devoted (one from ACB and one from CIB) to develop a comprehensive disaster 
recovery plan for the combined entity, with a focus on further development of 
Americorps' Y2K contingency plans.
    
   
     Americorp has created a budget specific to Y2K readiness.  The budget is 
comprised of the following components:  (1)  Consulting assistance for 
testing, (2)  Auditing, and (3)  Operating system and network upgrades.  This 
component is budgeted at $97,269.00.  As of October 29, 1998, $26,510.00, or  
27.3%  has been spent.   Senior Management reviews the budget from time to 
time as the Year 2000 Plan is implemented.  There is no assurance that 
additional amounts will not be added to the amounts already budgeted for Y2K 
expenditures.  With respect to components number (1) and (2), it should be 
noted that Americorp has engaged the services of three consulting firms that 
have or are currently providing audit review of the effectiveness of the Year 
2000 Plan and technological assistance in preparing for and conducting ACB's 
testing plan.   Their fees, estimated to be approximately $20,000.00 
combined, have yet to be expensed. 
    
   
     In addition, Americorp has dedicated significant human resources to the 
Year 2000 Plan.  This includes the salaries and benefits of personnel 
devoting significant time to the plan.  As of October 1, 1998, Americorp had 
expended over $40,000.00 in "man-hours" to the project, equivalent to 
twenty-eight work weeks.  In addition, expenditures have been made in the 
areas of advertising and public relations, customer and employee awareness 
programs and more.
    

   
     In April of 1998, Americorp initiated a credit risk assessment program, 
with loan officers completing a Y2K questionnaire for all new and renewed 
credits in amounts over $100,000.00.  These questionnaires were designed to 
provide Americorp's management with information by which it could evaluate 
the borrower's awareness of and sensitivity to Y2K risk.  Questionnaires are 
reviewed and discussed at weekly Officer Loan Committee meetings and are 
further reviewed by Credit Administration and a Senior Lender to ascertain 
Y2K risk associated with the credit.  As a result of this review, $85,000.00 
has been allocated to Americorp's loan loss provision.  In addition, legal 
language addressing Y2K issues is included in significant commitment letters 
and loan documentation for certain borrowers.  Finally, on loan 
participations purchased, Americorp requires assurances from the lead lender 
that it has obtained a Y2K questionnaire from the borrower and also that the 
lead lender is satisfactorily progressing toward Y2K compliance.
    

     Although Americorp believes that its Year 2000 Plan and other steps
being taken are adequate to ensure that it will not be materially affected by
the Year 2000 problem, there can be no assurance that the Year 2000 Plan and
Americorp's other year 2000 remedial and contingency plans will fully protect
Americorp from the risks associated with the Year 2000. The analysis of, and
preparation for, the Year 2000 and related problems necessarily rely on a
variety of assumptions about future events and there can


                                      34

<PAGE>

be no assurance that Americorp Management has accurately predicted such
future events or that the remedial and contingency plans of Americorp will
adequately address such future events. In the event that the business of
Americorp, of vendors of Americorp or of customers of Americorp is disrupted
as a result of the Year 2000 problem, such disruption could have a material
adverse effect on Americorp.
   
     CIB has established a working committee of senior management, a 
director and other employees to plan and monitor CIB's compliance with Year 
2000 ("Y2K") issues.  This committee has developed a policy setting forth 
priorities and a timetable for CIB to follow in this process.  The Federal 
Reserve Bank in their most recent examination has indicated that CIB was in 
compliance with the progress standards established by the Federal Reserve Bank 
with Y2K issues.  See "BUSINESS OF CIB - Year 2000 Issues" for additional 
information concerning CIB's compliance with Y2K issues.
    
   
     CIB and ACB intend that the CIB computer systems will be converted to the 
ACB computer systems shortly after consummation of the Merger.  However, there 
is no assurance that conversion to ACB's computer systems will occur at the 
planned level of expense, successfully avoid degradation in customer service or 
avoid other negative impacts to the combined entity's financial performance.
    
   
     SHARES ELIGIBLE FOR FUTURE SALE; DILUTION OF VOTING AND VALUE; POSSIBLE 
ANTI-TAKEOVER EFFECT .Shares of Americorp Stock eligible for future sale 
could have a dilutive effect on the market for Americorp Stock and could 
adversely affect market prices. As of the Americorp Record Date, the Articles 
of Incorporation of Americorp authorize 2,500,000 shares of Americorp Stock, 
of which _______ shares were outstanding, and _________ additional shares of 
Americorp Stock are anticipated to be issued in the Merger to CIB 
Shareholders, assuming (i) no shares of CIB Stock reserved for issuance on 
the Americorp Record Date are issued on or prior to the Effective Time, (ii) 
the estimated Exchange Ratio is .7000, (iii) the CIB Book Value Per Share is 
$13.96, (iv) Americorp Book Value Per Share is $20.02, (v) no Dissenters' 
Rights are perfected by CIB or Americorp Shareholders, and (vi) no cash is 
paid in lieu of fractional shares. Pursuant to its stock option plans, 
Americorp had outstanding options to purchase an additional _____ shares of 
Americorp Stock on the Americorp Record Date with exercise prices of between 
$____ and $____.
    
   
     Americorp may pursue acquisitions of other financial institutions from
time to time where such acquisitions are believed by Americorp to enhance
shareholder value or satisfy other strategic objectives, although there are
no specific pending or contemplated acquisitions at present. Such
acquisitions, if any, could be accomplished by the issuance of additional
shares of Americorp Stock or other securities convertible into or exercisable
for Americorp Stock.
    
     The Americorp Articles authorize the issuance of 2,500,000 shares of
Americorp Stock. The shares of Americorp Stock were authorized in an amount
greater than that to be issued to provide Americorp's Board of Directors with
as much flexibility as possible to effect, among other transactions,
financings, acquisitions, stock dividends, stock splits and the exercise of
employee stock options. However, these additional authorized shares may also
be used by the Board of Directors consistent with its fiduciary duty to deter
future attempts to gain control of Americorp.

     There can be no assurance as to the market value of Americorp Stock
after the Merger, which market value may be affected by the dilutive effects
of the matters described above, if any, and other factors.

     RISK FACTORS RELATING TO THE INDUSTRY
   
     CHANGING INTEREST RATES. Banking companies' earnings depend largely on the
relationship between the cost of funds, primarily deposits, and the yield on
earning assets. This relationship, known as the interest rate spread, is
subject to fluctuation and is affected by economic and competitive factors
which influence interest rates, the volume and mix of interest-earning assets
and interest-bearing liabilities, and the level of nonperforming assets.
Fluctuations in interest rates affect the demand of customers for CIB's and
ACB's products and services. CIB and ACB are subject to interest rate risk to
the degree that their interest-bearing
    
                                      35

<PAGE>

liabilities reprice or mature more slowly or more rapidly or on a different
basis than their interest-earning assets. Given CIB's and ACB's current
volume and mix of interest-bearing liabilities and interest-earning assets,
CIB's and ACB's interest rate spread could be expected to increase during
times of rising interest rates and, conversely, to decline during times of
falling interest rates. Therefore, significant fluctuations in interest rates
may have an adverse effect on ACB's results of operations.

   
     CHANGING ECONOMIC CONDITIONS AND GEOGRAPHIC CONCENTRATION IN ONE MARKET. 
The operations of CIB and Americorp are located in Ventura County. As a 
result of this geographic concentration, CIB's and Americorp's results depend 
largely upon economic conditions in this area. A deterioration in economic 
conditions in this market area could have a material adverse impact on the 
quality of CIB's and Americorp's loan portfolio and the demand for their 
products and services and, accordingly, their respective results of 
operations.
    
   
     IMPACT OF CHANGES IN GOVERNMENT REGULATION AND MONETARY POLICY. The 
banking industry is subject to extensive federal and state supervision and 
regulation. Such regulation limits the manner in which CIB, ACB and Americorp 
conduct their respective businesses, undertake new investments and activities 
and obtain financing. This regulation is designed primarily for the 
protection of the deposit insurance funds and consumers, and not to benefit 
holders of CIB's or Americorp's Stocks. Financial institution regulation has 
been the subject of significant legislation in recent years, and may be the 
subject of further significant legislation in the future, none of which is in 
the control of CIB or Americorp. Significant new laws or changes in, or 
repeal of, existing laws may cause CIB's or Americorp's results to differ 
materially. Further, federal monetary policy, particularly as implemented 
through the Federal Reserve System, significantly affects credit conditions 
for financial institutions, primarily through open market operations in 
United States government securities, the discount rate for bank borrowings 
and bank reserve requirements. Any material change in these conditions would 
be likely to have a material impact on CIB's and Americorp's respective 
results of operations.
    
   
     ABILITY TO COMPETE. The banking and financial services business in 
California generally, and in CIB's and Americorp's market area specifically, 
is highly competitive. The increasingly competitive environment is a result 
primarily of changes in regulation, changes in technology and product 
delivery systems and the accelerating pace of consolidation among financial 
services providers. ACB and CIB compete for loans, deposits and customers for 
financial services with other commercial banks, savings and loan 
associations, securities and brokerage companies, mortgage companies, 
insurance companies, finance companies, money market funds, credit unions and 
other nonbank financial service providers. Many of these competitors are much 
larger in total assets and capitalization, have greater access to capital 
markets and offer a broader array of financial services than ACB or CIB. 
There can be no assurance that ACB will be able to compete effectively in its 
markets, and the results of operations of ACB and Americorp could be 
adversely affected if circumstances affecting the nature or level of 
competition change.
    
   
     LOSSES AND IMPAIRED CREDIT QUALITY. A significant source of risk for 
financial institutions such as ACB and CIB arises from the possibility that 
losses will be sustained because borrowers, guarantors and related parties 
may fail to perform in accordance with the terms of their loans. CIB and ACB 
have adopted underwriting and
    
                                      36

<PAGE>

credit monitoring procedures and credit policies, including the establishment
and review of the allowance for credit losses, that each company's respective
management believes are appropriate to minimize this risk by assessing the
likelihood of nonperformance, tracking loan performance and diversifying the
respective credit portfolios. Such policies and procedures, however, may not
prevent unexpected losses that could materially adversely affect the results
of operations.

                                 THE CIB MEETING

     DATE, TIME AND PLACE

     The CIB Meeting will be held on _________, ________, 1998 at

by approximately ___________ shareholders of record.

     PROXIES AND REVOCABILITY OF PROXIES

     A proxy card for voting at the CIB Meeting is enclosed with the copy of
this Joint Proxy Statement/Prospectus being mailed to CIB shareholders. (A
separate proxy card for Americorp shareholders voting at the Americorp
Meeting is being provided to Americorp shareholders. See "THE AMERICORP
MEETING-Proxies and Revocability of Proxies."). When a proxy card is
returned, properly signed and dated, the shares represented thereby will be
voted in accordance with the instructions on the proxy card. If a shareholder
does not attend the CIB Meeting and does not return the signed proxy card,
such holder's shares will not be voted and this will have the effect of a
vote "AGAINST" the matter to be voted on at the CIB Meeting. Shareholders are
urged to mark the box on the proxy card to indicate how the shares
represented by the proxy card are to be voted. If a shareholder returns a
signed proxy card


                                      37

<PAGE>

but does not indicate how his or her shares are to be voted, such shares will
be voted "FOR" the proposal. The proxy card also confers discretionary
authority on the individual appointed by the CIB Board named on the proxy
card to vote the shares represented thereby on any other matter that is

broker non-votes with respect to the proposal concerning approval of the
Agreement and the transaction contemplated thereby will have the same effect
as a vote "AGAINST" the proposal.

                                  THE MERGER

     The Agreement provides for, among other things, (i) the merger of CIB
with and into ACB with ACB as the surviving bank, and (ii) the shareholders of
CIB becoming shareholders of Americorp in accordance with the Exchange Ratio,
all subject to the terms and conditions specified in the Agreement.

   
     The Merger is intended to be a so-called "Merger of Equals" whereby 
comparatively similar sized financial institutions and their respective 
managements, boards of directors, shareholder groups and businesses are 
combined to create an institution which may provide for, among other things, 
increased synergies, expended products and markets, higher lending limits and 
a reduction of overall overhead costs, including a reduction in duplicate 
positions and employee benefits.  Such mergers may also enhance the liquidity 
of a shareholder's investment and may provide the combined entity with easier 
access to the capital markets.  "Mergers of Equals" provide the same types of 
risk associated with combining any two entities, including (i) the 
disadvantages of being part of a larger entity, including reduced voting 
power and the potential for decreased customer service; (ii) the integration 
of the different corporate cultures of the entities will divert the combined 
entities' management time from other activities and (iii) the proposed 
changes to policies and procedures of the combined entity may not prove to be 
successful to the customers of the combined entity.  "Mergers of Equals" also 
generally provide, among other less favorable aspects, a smaller premium on 
their investment to the non-surviving institutions' shareholders than would 
be anticipated in an actual sale of control, less liquidity to such 
shareholders for their investment than if the non-surviving institution had 
been acquired by a larger acquiror as well as the difficulties associated 
with combining the human resources and cultural differences of two similar 
sized institutions.
    

     Certain provisions of the Agreement are summarized below. This summary 
does not purport to be complete and is qualified in its entirety by reference 
to the complete text of the Agreement, which is reprinted as Appendix A to 
this Joint Proxy Statement/Prospectus and is incorporated herein by 
reference. Shareholders of CIB and Americorp are urged to read the Agreement 
in its entirety.

     BACKGROUND AND REASONS FOR THE MERGER AND MANAGEMENT'S 
     RECOMMENDATION--AMERICORP

     The Board of Directors of Americorp began to consider the possibility
of a "merger of equals" with or acquisition of another financial institution
during March, 1998. In the current financial services environment, a merger or
acquisition would support Americorp's strategic objective of remaining a
preeminent independent financial services provider in Ventura County, while
strengthening management, growth opportunities and profitability. Furthermore,
it is believed that ACB, as a larger independent bank, will be able to compete
with major banks in the communities served, providing superior products and
services to the marketplace.

   
     In its considerations, Americorp determined that a "Merger of 
Equals" transaction with CIB should first be explored (as opposed to mergers 
with or acquisitions of other institutions) because of its complimentary 
markets and similar operating philosophy. Discussions concerning the 
possibility of a business combination among the Parties began during late 
March and early April of 1998 with a series of meetings between various 
directors of the institutions. These meetings resulted in the chairmen of 
Americorp and CIB meeting on April 9, 1998 to discuss various issues relating 
to the combination. The discussions between the two chairmen continued on 
through April and May. On May 14, 1998, a confidentiality agreement was 
signed to facilitate mutual due diligence and transfers of information. Both 
Parties conducted due diligence during various periods in May and June.
    

     In late May and early June, Americorp held discussions with 
Cal.Research relating to their engagement to render a fairness opinion in 
connection with the transaction. Counsel was also authorized to commence 
drafting of the Agreement and a first draft of the Agreement was delivered to 
CIB on or about June 6. Negotiation of the transaction continued through 
various drafts of the Agreement and were principally conducted through a 
series of meetings between the chairmen of the Parties during mid and late 
June. On July 2, both chairmen met along with President Lukiewski and Ms. 
Pruner to resolve remaining issues.

   
     In the course of negotiations, Americorp proposed that the 
respective book values of the Parties, subject to certain adjustments, was a 
proper methodology to determine the Exchange Ratio in the Merger.  While some 
"Merger of Equals" are structured on the basis of an Exchange Ratio 
formulated from the market capitalization of the respective institutions, 
Americorp concluded that the thinly traded nature of the markets for its and 
CIB Stocks made book value a better basis for determining the Exchange Ratio. 
Additionally, the use of a book value based Exchange Ratio provided the CIB 
shareholders a premium on their CIB Stock in the Merger based upon the then 
trading value of shares of Americorp Stock.
    

     At a meeting on the morning of July 7, 1998, the Boards of Directors 
of Americorp and ACB met to discuss further the Agreement and the Merger. At 
such meeting, the Board received the oral opinion of Cal.Research which was 
later confirmed in writing that the combination was fair from a financial 
point of view to the Americorp shareholders and counsel reviewed the terms of 
the Agreement and the transactions contemplated thereby. The Board 
unanimously approved the Agreement and the transaction

                                      41

<PAGE>

contemplated thereby at such meeting.

     The Agreement was signed during the afternoon of July 7, 1998.

     It is important to Americorp's Board of Directors to continue to 
offer local management and ongoing support to the communities ACB has served 
since its founding. That same philosophy is shared by CIB and, as a result of 
that conviction provides a great opportunity to combine the two institutions. 
CIB possesses an excellent customer and deposit base in Oxnard which 
compliments ACB's existing customer and deposit base and provides the 
combined organization a more competitive share of the market in Ventura 
County.

     The Board and management of Americorp also anticipate that the 
Merger will provide the potential to benefit from revenue enhancement 
opportunities. These opportunities result from, among other factors: (1) the 
enhanced ability to better serve the marketplace; (2) the ability to 
cross-sell a wider variety of banking products and services; (3) the ability 
to generate increased loan and fee income by providing higher lending limits; 
(4) the potential to increase overall market share in the communities served; 
(5) the opportunity to increase the loan portfolio; and (6) the ability to 
create more efficiencies, thereby reducing overall operating costs to both 
institutions. Additionally, the Board of Directors also considered that the 
larger size of the surviving bank, along with Americorp's intention to 
explore listing the Americorp Stock on Nasdaq would increase shareholder 
liquidity.

     In reaching its conclusion, Americorp's Board of Directors 
considered information and advice from several specialists including 
Cal.Research and legal advisors. After consideration of the financial 
performance, business operations, capital levels, and asset quality of the 
institutions, it was decided to pursue a combination of the Parties.

   
     The Board of Directors of Americorp believes that the terms of the 
Merger are fair to and in the best interests of Americorp and its 
shareholders. In addition to the considerations already described, in 
unanimously approving the Agreement, the Board of Directors considered the 
following factors (constituting all the other material factors considered by 
the Board), without assigning any specific or relative weights to the 
factors:
    

         (i)   The Board of Directors believes that the Exchange Ratio 
provided for in the Agreement represents fair consideration. In addition, 
Cal.Research concluded that the terms of the Merger are fair to the 
stockholders of Americorp from a financial point of view.

         (ii)  It is anticipated that the Merger will increase the liquidity 
of the stock by expanding the size of the shareholder base.

         (iii) It is expected that the Merger will result in better
opportunities to lend to a more diverse customer base.

         (iv)  The Merger is expected to result in a strong, deep management
team that will allow


                                      42

<PAGE>

Americorp to address more effectively changes in technology, regulation,
competition, products and services.

     (v)   The capital of the combined institutions will provide an
excellent opportunity to expand and leverage the overall expense structure of
the combined institutions.

     Accordingly, Americorp's Board of Directors has approved the 
Agreement and the transactions contemplated thereby and recommends approval 
of the same by the shareholders of Americorp.

     BACKGROUND AND REASONS FOR THE MERGER AND MANAGEMENT'S 
     RECOMMENDATION--CIB

     Channel Islands Bank is proud of its community bank roots, and its
banking philosophy is deeply steeped in the independent bank tradition of
customer service and community involvement. CIB conducts general banking
operations in Camarillo and Oxnard, Ventura County, California. In serving
individuals, small businesses and mid-market corporations, CIB historically
has focused on a community-based approach to banking.

     From time to time in 1997 and 1998, CIB had meetings and discussions
with a number of institutions with respect to potential acquisitions and
business combinations. The institutions that discussed certain business
combinations with CIB were only those institutions that focused on the
community-based approach to banking and were located in markets that would
provide CIB with both strategic and synergistic benefits. One of the
institutions that CIB had such discussions with was Americorp and ACB.

     After several informal discussions, both CIB and Americorp began to
realize that in order to compete more effectively with the larger financial
institutions resulting from the various consolidations and mergers in the
industry locally, both institutions needed to increase in size, and both CIB
and Americorp saw the advantages of a potential business combination. At the
same time, each recognized the opportunity to build a larger regional,
independent financial institution in the Ventura County market.

     In the second quarter of 1998, the principals of CIB and Americorp met 
several times to preliminarily discuss the possible synergies between the 
companies. CIB and Americorp thereafter continued to discuss a possible 
combination of the companies. In June, 1998, Americorp presented a proposal 
to CIB that provided for a financial structure of a tax-free exchange of 
stock to be accounted for on a pooling-of-interest basis, and such proposal 
was described to the CIB Board on June 1, 1998. At meetings over the 
following several weeks, the principals of CIB and Americorp further 
discussed a proposed merger of CIB and Americorp. At the June 18, 1998 
meeting of the CIB Board, Mr. Priske described the operations of Americorp 
and ACB, the proposed merger terms and plans for CIB's offices and staff 
following the proposed merger. The CIB Board considered this information and 
then authorized Mr. Priske to proceed to negotiate a tentative merger 
agreement between CIB and Americorp. The CIB Board also authorized management 
to select appropriate legal counsel and financial advisor to advise it

                                      43

<PAGE>

on the strategic alternatives available to CIB. Thereafter, CIB retained
Knecht & Hansen as its legal advisor and the Findley Companies ("Findley") as
its financial advisor to issue a fairness opinion in connection with CIB's
consideration of the merger proposal from Americorp.

     Following continued negotiations between the representatives of CIB 
and Americorp, on July 7, 1998, the CIB Board deliberated at length 
concerning the transaction and to review the Agreement and related documents, 
its strategic alternatives, the competitive banking environment in 
California, the prospects for CIB if it remained independent and the results 
of the due diligence review of Americorp and ACB performed by CIB management, 
legal counsel and accountants conducted in June and early July, 1998. At this 
meeting, Findley discussed with the CIB Board its analysis of the Merger and 
delivered to the CIB Board its opinion that the consideration to be received 
in the Merger was fair to the CIB shareholders from a financial point of view 
(see "CIB Fairness Opinion"). Thereafter, the CIB Board approved, and 
authorized the execution of, the Agreement.

     The CIB Board unanimously approved the Merger at its Board of 
Directors meeting on July 7, 1998. The CIB Board believes that the terms of 
the Merger are fair to, and in the best interests of, CIB and its 
shareholders and recommends that the shareholders of CIB vote FOR approval of 
the Merger.

     In reaching its conclusion, the CIB Board considered information 
provided at meetings of its Board of Directors in June 1998 and July 1998, 
including, among other things, (i) information concerning the financial 
performance and condition, business operations, capital levels, asset 
quality, loan portfolio breakdown, due diligence review of the loan 
portfolio, material contracts, contingent liabilities of Americorp and ACB, 
and prospects of Americorp and ACB; (ii) the structure of the transaction, 
including the fact that the CIB shareholders would receive approximately 40% 
of the common equity of Americorp on a fully diluted basis; (iii) the fact 
that Mr. Priske would serve as Vice Chairman of the Board of Directors of 
Americorp and ACB, that the Board of Directors of Americorp and ACB would be 
comprised of four directors from CIB, the total number of directors of 
Americorp and ACB would total nine; (iv) the terms of the Merger Agreement 
and other documents to be executed in connection with the Merger, including 
the covenant of Americorp in the Agreement allowing CIB to pay semi-annual 
dividends to the shareholders of CIB; (v) the presentation of Findley and the 
opinion of Findley that the Merger is fair to the shareholders of CIB from a 
financial point of view; (vi) the results of its due diligence examination of 
Americorp and ACB; (vii) the terms of other recent comparable combinations of 
banks and bank holding companies; (viii) the CIB Board's review with its 
legal and financial advisors of alternatives to the Merger, the range of 
possible values to CIB shareholders obtainable through implementation of 
alternatives and the timing and likelihood of the same; (ix) the current and 
prospective economic environment and regulatory and competitive burdens and 
constraints facing community banks; (x) the pro forma financial statements of 
the combined companies and the capitalization of the combined companies; (xi) 
the CIB Board's review with its legal and financial advisors of potential 
merger targets; (xii) the compatibility of CIB with Americorp and ACB and the 
complementary lines of business; (xiii) the geographic distribution of 
Americorp and ACB offices vis-a-vis CIB's strategic plan; (xiv) the 
advantages of being part of a larger entity, including the potential for 
operating efficiencies, the effect of a higher lending limit on CIB's 
customers and prospective customers, and the generally higher trading 
multiples

                                      44

<PAGE>


of larger financial institutions; (xv) the business strategies, the strength
and depth of management of the combined entity and the extent of their
interest in continuing CIB's significant business relationships in Ventura
county; (xvi) the ability of a larger institution to compete in the banking
environment and to leverage overhead costs; (xvii) the effect of the Merger
on existing shareholders, employees, officers and customers of CIB; (xviii)
the current and prospective economic environment and regulatory and
competitive burdens and constraints facing commercial banks; (xix)
information concerning the ability of CIB and ACB to achieve operating
efficiencies; (xx) the impact on the communities served by CIB and ACB in the
Merger, and the increased ability to serve the communities through the larger
branch network; (xxi) the unprecedented consolidation currently underway in
the banking industry and increased competition from larger independent banks
in California; (xxii) the value of the consideration offered by Americorp
compared to the value of the consideration offered in other acquisitions of
financial institutions in California in 1996, 1997 and 1998 and the prospects
for enhanced value of the combined entity in the future; (xxiii) the tax-free
nature of Americorp offer; (xxiv) the intention of the parties that Americorp
Stock may be listed on Nasdaq in one year of the consummation of the
Agreement and the future liquidity of Americorp Stock; and (xxv) the
prospects and valuation of CIB on a stand alone basis and on the basis of
alternative stand alone strategies, such as dividends, share repurchases,
restructurings and growth through acquisitions.

   
     In addition to the advantages of a "Merger of Equals" whereby 
comparatively similar sized financial institutions and their respective 
managements, boards of directors, shareholder groups and businesses are 
combined to create an institution which may provide for the advantages 
discussed in the previous paragraph, the management of CIB also discussed the 
various risks of combining with Americorp in a "Merger of Equals," including 
(i) the disadvantages of being part of a larger entity, including reduced 
voting power on the Americorp and ACB Board of Directors and the potential for 
decreased customer service; (ii) the integration of CIB and ACB will divert the 
combined entities' management from other activities; (iii) since CIB's market 
area is located geographically south of ACB's market area, with generally 
little geographical overlap in the market areas of CIB and ACB, and because CIB 
and ACB have two different cultural orientations, as CIB is more commercially 
oriented and ACB is more consumer oriented, the Merger will introduce the 
combined entity to new markets and cultures, and no assurance can be given that 
the combined entities' policies, procedures and products will prove successful 
in the combined market areas and in a combined commercial and consumer culture; 
(iv) a smaller premium on CIB shareholder investment than would be anticipated 
in an actual sale or acquisition of CIB; and (v) less liquidity to the CIB 
shareholders for their investment than if CIB had been acquired by a larger 
financial institution.
    
   
     However, after weighing the advantages and disadvantages of a "Merger of 
Equals" with Americorp and ACB, the CIB Board of Directors determined that 
the advantages clearly outweighed the disadvantages of the Merger with 
Americorp and ACB.  For example, (a) many of the CIB policies and procedures 
are or will be adopted on a going forward basis by ACB; (b) CIB obtained 
greater representation on the proposed Board of Americorp and ACB than would 
be expected in a normal acquisition or sale transaction or in a "Merger of 
Equals" based solely on asset size; (c) both entities have formed joint 
personnel and other committees while the transaction is pending in order to 
integrate the two entities as completely as possible before the Merger is 
completed, thereby resulting in less diversion of management to integration 
activities; (d) the smaller premium in this transaction is expected to be 
more than offset by a relatively larger value for all shareholders of the 
combined entity in the future; and (e) the combined entity expects to have 
its stock listed on Nasdaq in the near future, thereby increasing the 
liquidity of the combined entities' outstanding stock. 
    
   
     The CIB Board of Directors also considered several methods of 
converting the CIB shares to Americorp shares, including an exchange based 
upon book value as of a date just prior to consummation and an exchange of 
stock based upon market valuation of the two entities.  The CIB Board of 
Directors concluded that the market for CIB and Americorp stock was so thinly 
traded that the market did not necessarily reflect the value of each 
organization, and that an exchange based upon the book values of each 
organization, as adjusted as provided in the Agreement, would be a better 
measure of each entities' value in the Merger.  In addition, the use of a 
book value based Exchange Ratio provided the CIB Shareholders a premium on 
their CIB Stock in the Merger based upon the then trading value of shares of 
Americorp Stock. 
    

     The managements of CIB and Americorp saw opportunities for increased 
operating efficiencies. In particular, the managements believe that cost 
savings can be achieved as a result of economies of scale, the combination of 
executive management and elimination of certain central staff, the 
consolidation of data processing and operations activities and the 
elimination of duplicative administrative functions. There can be no 
assurance that Americorp and ACB will be able to realize fully the increased 
operating efficiencies or that such operating efficiencies will be realized 
in a timely manner.

     Managements of CIB and Americorp believe that each complements each 
other both in their community-based approach to banking and in terms of 
geographic service areas. Consequently, CIB and Americorp believe that by 
combining forces, CIB and Americorp will be able to more effectively compete 
and successfully to take advantage of banking opportunities in the Southern 
California market.

     The foregoing discussion of the information and factors considered by
the CIB Board is not intended to be exhaustive, but constitutes the material
factors considered by the CIB Board. In reaching its determination to approve
and recommend the principal terms of the Merger, the CIB Board did not assign
relative or specific weights to the foregoing factors and individual directors
may have weighed such factors differently.

     FOR THE REASONS SET FORTH ABOVE, THE CIB BOARD HAS UNANIMOUSLY 
APPROVED THE AGREEMENT AS IN THE BEST INTEREST OF CIB AND ITS SHAREHOLDERS 
AND UNANIMOUSLY RECOMMENDS THAT THE CIB SHAREHOLDERS APPROVE THE PRINCIPAL 
TERMS OF THE MERGER.

of view. No limitations were imposed by the Americorp Board of Directors upon
Cal.Research with respect to the investigations made or procedures followed
in rendering the Opinion.

IN ITS ENTIRETY BY REFERENCE TO THE TEXT OF SUCH OPINION. CAL.RESEARCH'S 
OPINION THAT THE MERGER IS FAIR FROM A FINANCIAL POINT OF VIEW TO 
SHAREHOLDERS OF AMERICORP IS DIRECTED TO THE AMERICORP BOARD OF DIRECTORS AND 
IS DIRECTED ONLY TO THE CONSIDERATION TO BE PAID BY AMERICORP IN THE MERGER 
AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY AMERICORP SHAREHOLDER AS TO 
HOW SUCH SHAREHOLDER SHOULD VOTE AT THE AMERICORP MEETING.
    
   
     In rendering our opinion, Cal. Research has relied upon and assumed 
the accuracy, completeness and fairness of all of the financial and other 
information that was available to us from public sources and that was 
provided to us by Americorp and CIB. Cal. Research has not assumed any 
responsibility for independently verifying such information nor undertaken an 
independent evaluation or appraisal of any of the assets or liabilities of 
Americorp or been furnished with any such evaluation or appraisal.
    

     Cal. Research has, among other things:

          (1) Reviewed the Agreement by and among ACB, Americorp and
          CIB;

          (2) Reviewed certain publicly available business and financial
          information on the banks of Ventura County;

          (3) Reviewed certain other companies that Cal. Research
          considered relevant and compared them to ACB and CIB from a
          financial point of view.

          (4) Reviewed call reports to the banking regulators for
          Americorp and CIB for the periods ending December 31, 1995,
          December 3l, 1996, December 31, 1997, and March 31, 1998. Cal.
          Research has also reviewed the Annual Reports to shareholders
          for the


                                      46

<PAGE>


          years 1995, 1996, and 1997 for each company;

          (5) For each company Cal. Research has also reviewed
          information pertaining to classified or criticized loans,
          premises, lease terms of office facilities, internal financial
          reports, litigation reports, summaries of stock options, stock
          prices for the last four quarters, and other data provided us
          by the senior management personnel of each institution. Cal.
          Research also reviewed a pro-forma analysis of both banks as
          provided by ACB's President/CEO.

          (6) Considered the financial terms of companies involved in
          comparable business consolidations.

Set forth below is a brief summary of the analysis performed by Cal. Research
in reaching its opinion. Cal. Research assumed for purposes of its opinion
that the Merger will be accounted for as a pooling of interests transaction
under generally accepted accounting principles. An exchange ratio of 0.6338
shares of Americorp's stock for each share of CIB stock at time of closing,
the level at which CIB shares would be exchanged if the Effective Time (as
defined in the Agreement) were the same as the date of the opinion was
assumed. The Exchange Ratio was developed pursuant to extensive negotiations
between Americorp and CIB.

          1.   PRO-FORMA MERGER AND CONTRIBUTION ANALYSIS

          Cal. Research analyzed the changes in the earnings, book value and
     dividends attributable to one share of Americorp stock before the Merger to
     those attributable to a share of stock resulting from the merger.

          The analysis assumed a dividend pay-out ratio of 40% to 45% of
     earnings as is consistent with Americorp's recent historical experience.
     The analysis assumes that merger-related operating cost savings to be fully
     realized during 1998 and each year thereafter and assumes the merger is
     completed by the end of 1998. Merger-related costs were assumed to be
     charged off during 1998.

          The impact on ACB of volatility in CIB's earnings was shown by
     calculating pro-forma results assuming CIB's earnings were as projected as
     well as 125% of projections. Also, pro-forma results assuming 125% of
     projected cost savings were realized and projections assuming 75% of
     projected cost savings were realized were made for the post-merger bank.

          The projected merger cost savings approximate 6.4% of the combined
     institutions' projected non-interest expense. This ratio is in line with
     other mergers reviewed by Cal. Research.

          Pro-forma merger analyses assuming stated earnings projections and
     the Merger-related cost savings projected by ACB were made. CIB's earnings
     volatility was considered by calculating projected earnings as well as 125%
     of projections. Also, 75% of projected earnings were taken into account.


                                      47

<PAGE>


     Cal. Research analyzed the changes in earnings, book value and
dividends for the years 1999, 2000 and 2001 and included various
combinations of stand-alone and pro-forma projected earnings and cost
savings volatility assumptions as described previously.

     Results showed that for 1999, on a stand-alone basis, earnings 
for ACB were $1.82 per share and for the Surviving Bank would be $2.33 per 
share. Assuming 75% merger cost savings, the Surviving Bank would earn $2.14 
per share for 1999. Assuming 125% merger cost savings, the Surviving Bank 
would earn $2.53 per share for 1999.

   
     At July 6, 1998, the last trading day before the announcement of the 
Merger, the closing bid price for Americorp's stock was $32.00 per share.  On 
a stand-alone basis earnings for Americorp would be $1.82 for 1999 and at 
17.0 times earnings, the market value would be $30.94.  For the combined 
institution 1999 earnings would be $2.33 per share, and at 17.0 times 
earnings the indicated market value would be $39.61.
    
   
     Assuming 75% of cost savings can be achieved, the combined institution 
would earn $2.14 for 1999, and at 17.0 times earnings the market value would 
be $36.38.
    

     Results for 2000 range from $2.02 per share to $2.92 to $3.31 per
share.

   
     For the year 2000 market values would range from $49.64 if 75% of Merger 
cost savings are achieved and $52.87 if %100 of Merger cost savings are 
achieved.
    

     Results for 2001 range from $2.22 per share to $3.55 per share.

     2.   ANALYSIS OF OTHER MERGER TRANSACTIONS

     Cal. Research reviewed the results of 18 merger and acquisition 
transactions made throughout California during 1996 and 1997. Assets for 
acquired institutions were over $100 million but less than $500 million. The 
median price/tangible book ratio for these transactions was 1.90 times book 
while the median price/earnings ratio was 17.55 times.

   
     The book value of Americorp on a stand-alone basis as of June 30, 1998 
was $20.00 per share.  At a multiple of 1.90 times book, the market price 
would be $38.00. For the combined institution on the same date the book value 
was $19.66 with the market value being $37.35 given a multiple of 1.90 times 
book.
    

     A review of 71 independent banks in the Hoefer & Arnett Banking Universe 
revealed the median price/earnings ratio to be 16.98 times and the median 
price/tangible book value ratio to be 2.16 times. These ratios were used in 
the following cash flow analysis.

     3.   DISCOUNTED CASH FLOW ANALYSIS

     Cal. Research undertook a cash flow analysis in order to compare the 
present value if Americorp remained independent through 2001 or was acquired 
in 2001 by another institution. The results produced in the analysis did not 
purport to be indicative of actual values or expected values of Americorp. 
Rather, the values obtained through the discounted cash flow analysis 
analyzed the effect of possible earnings volatility and potential 
Merger-related operating cost savings volatility. Various levels of earnings 
for ACB and CIB were examined.

     Cases examined were: ACB on a Stand-Alone basis, CIB on a Stand-Alone 
basis, ACB and CIB on a Combined Basis, a Combined Bank Assuming 75% of 
Projected Operating Cost Savings Were Realized, Combined Bank Assuming 125% 
of Projected Cost Savings Were Realized and Combined Bank Assuming ACB had 
made only 75% of Projections but CIB made 125% of Projections.

     The Discount Rates ranged from 8.0% to 12.0% over a three-year period. A 
Terminal Price multiple, applied to Year 2000 estimated earnings per share 
was the California median in the Fourth

                                      48

<PAGE>

Quarter of 1997, or 16.98 times earnings. Lower levels of price-to-earnings 
per share multiples would reflect an estimated future trading range of 
Americorp, while higher levels of price-to-earnings multiples are more 
indicative of a future sale of the stock of Americorp to a larger financial 
institution.

     For the ACB Stand-Alone Analysis, the cash flows were comprised of 
dividends projected for the years 1999, 2000 and 2001 plus the Terminal Value 
of Americorp stock at year-end 2001 (calculated by applying the assumed 
terminal price to earnings ratio (16.98 times) to projected ACB earnings per 
share.

     For the combined bank analysis the cash flows were projected pro-forma 
dividends in years 1999, 2000 and 2001 plus the Terminal Value of the 
pro-forma combined entity's stock at year-end 2001.

     Cal. Research also calculated the present values that would be realized 
if 75% of the Projected Savings due to the merger were realized. Also, the 
analysis was done to review results if 125% of projected operating savings 
were obtained as well.

     Stand-Alone present values per share for Americorp ranged from
$39.66 to $39.88 per share while pro-forma combined present values ranged
from $59.48 to $59.77 per share and from $62.95 to $63.26 per share if 125%
of projected cost savings were realized.

   
     In comparison to these values the actual price per share traded over 
the counter for Americorp was approximately $32.00 at December 31, 1997. 
    
   
     It was previously noted that the market price was $32.00 per share on 
July 6, 1998 for Americorp Stock.  By 2001 the market price could by $59.77 
(earnings of $3.36 times P/E ratio of 16.98 plus present value of dividends 
at a 12% disount or $2.79).
    

     The results of these analyses do not purport to be indicative of actual 
or expected values per share of Americorp stock. Rather, these analyses are 
intended as a valuation technique, which relies on numerous assumptions, 
including asset and earnings growth rates, dividend pay-out rates, terminal 
values and a discount rate. A higher level of projected ACB earnings raised 
the resulting present value for a given level of Channel Islands' earnings on 
a pro-forma combined basis.

     COMPARABLE COMPANY ANALYSES

     Cal. Research examined recent historical data on Americorp and CIB based 
upon data from their 1995, 1996 and 1997 Annual Reports to Shareholders and 
subsequent quarterly data. Certain statistics were compared to data for a 
peer group of California banks using publicly available data contained in the 
Hoefer & Arnett Banking universe, 1997 Fourth Quarter. The Universe includes 
71 California banking institutions (neither CIB nor ACB are included in this 
group). Comparisons were made for the period ending December 31, 1997. Also, 
a data base of 66 California independent banks compiled by Sutro & Co. was 
reviewed for comparative purposes.

    CIB FAIRNESS OPINION

    CIB has retained The Findley Group ("Findley") to act as its
financial advisor in connection with the Merger pursuant to an engagement
letter dated May 26, 1998 (the "Engagement Letter"). Findley has rendered to
the Board of Directors of CIB its written opinion dated July 7, 1998, as
affirmed on _________, 1998, pursuant to the terms of the Agreement that,
subject to the assumptions and limitations set forth therein, the Exchange
Ratio is fair, from a financial perspective, to CIB shareholders. A copy of
the opinion dated July 7, 1998 of Findley is attached as Appendix B to this
Joint Proxy Statement/Prospectus and should be read in its entirety. The
following summary is qualified in its entirety by reference to the full text
of the opinion. This opinion is addressed to the Board of Directors of CIB
and does not constitute a recommendation to any shareholder of CIB as to how
such shareholder should vote at the CIB Meeting.

- ---------------------
1) Based on December 31, 1997 market price.
2) Non-performing assets are loans 90 days past due and still accruing and
   non-accrual and other real estate owned.
3) Efficiency ratio is non-interest expense as a percent of total revenues.


                                      50

<PAGE>

    In connection with its Fairness Opinion, Findley, among other things:
(a) reviewed certain publicly available financial and other data with respect to
CIB and Americorp, including the consolidated financial statements for recent
years and interim periods to March 31, 1998, the March 31, 1998 Call Reports for
CIB and ACB and certain other relevant financial and operating data relating to
CIB and Americorp made available to Findley from published sources and from the
internal records of CIB and Americorp; (b) reviewed the Agreement; (c) reviewed
certain historical market prices and trading volumes of CIB and Americorp Stock;
(d) compared CIB and Americorp from a financial point of view with certain other
companies that Findley deemed to be relevant; (e) considered the financial
terms, to the extent publicly available, of selected recent business
combinations of companies that Findley deemed to be comparable, in whole or in
part, to the Merger; (f) reviewed and discussed with representatives of the
management of CIB certain information of a business and financial nature
regarding CIB and Americorp furnished to Findley by CIB and Americorp, including
financial forecasts and related assumptions of CIB and Americorp; (g) made
inquiries regarding and discussed the Merger and the Agreement and other matters
related thereto with CIB's counsel; (h) reviewed litigation reports for both
CIB and Americorp; and (i) performed such other analyses and examinations as
Findley deemed appropriate.

    CONTRIBUTION ANALYSIS. Findley analyzed the contribution of each CIB
and Americorp to, among other things, common equity and net income of the pro
forma combined companies for the period ending December 31, 1997, adjusted
through March 30, 1998. This analysis showed, among other things, that based on
pro forma combined balance sheets and income statements for CIB and Americorp as
of December 31, 1997, adjusted through March 30, 1998, CIB would have
contributed 39.9% of the deposits, 38.7 percent of the shareholder equity of the
combined companies (before costs savings and revenue enhancements), 40.4 percent
of gross income, 42.7 percent of net income for 1997 and 37.4 percent of 1998
estimated net income. Based upon the stock consideration to be paid in the
merger as provided in the Agreement, the CIB shareholders would own
approximately 38.7% of the combined companies on March 30, 1998 and are
estimated to own in excess of such percentage at Closing based upon the Exchange
Ratio.

    DISCOUNTED CASH FLOW ANALYSIS. Findley examined the results of a
discounted cash flow analysis designed to compare the Exchange Ratio with the
present value, under certain assumptions, that would be attained if CIB remained
independent through 2001, at which time CIB was acquired by a larger financial
institution. The cash flows for the combined companies assumed that the Exchange
Ratio equals 0.69282 shares of Americorp for each share of CIB. The results
produced in the analyses did not purport to be indicative of actual values or
expected values of CIB or the combined companies at such future date. All cases
were analyzed assuming realization of operating cost savings, estimated by the
parties, in the amounts and time periods forecasted by the parties.

    The discount rates used ranged from 10% to 14%. For the CIB stand alone
analysis, the terminal price multiples applied to the 2001 estimated earnings
per share ranged from 12.0 to 20.0. The lower levels of the price to earnings
values multiples range reflected an estimated future trading range of CIB or the
combined companies, while the higher levels of the price to earnings value
multiples range were more indicative of a future sale of CIB or the combined
companies to a larger financial institution.


                                      51

<PAGE>

    For the CIB stand alone analysis, the cash flows were comprised of the
projected stand alone dividends of $0.20 per share in years 1998 through 2001
plus the terminal value of CIB Stock at the year-end 2001 (calculated by
applying each one of the assumed terminal price to earnings value multiples as
stated above to the 2001 projected CIB earnings per share). A similar analysis
was done for Americorp using a cash dividend rate of $0.84 per share and for the
combined companies. The discount rates described above were then applied to
these cash flows to obtain the present values per share of CIB Stock.

    Under a most likely scenario, the Findley analysis assumed that
projected earnings, among other things, would be achieved; that projected
operating cost savings are a minimum of $400,000 realized (for the combined
companies case) a present value discount rate of 12% and a terminal price to
earnings value multiple of 20.0. Assuming CIB remains independent through
2001 and is then acquired by a larger financial institution, a holder of one
share of CIB Stock today would receive cash flows with a present value of
$26.19. Assuming the Merger is consummated and that combined companies remain
independent through 2001 and is then acquired by a larger financial
institution, a holder of one share of CIB Stock today would receive cash
flows with a present value of at least $32.60.

    ANALYSIS OF SELECTED BANK MERGER TRANSACTIONS. Findley reviewed the
consideration paid in recently completed transactions whereby certain banks were
acquired. Specifically, Findley reviewed 71 transactions involving acquisitions
of selected banks in California completed since January 1, 1996 (the "California
Acquisitions"). For each bank acquired in such transactions, Findley compiled
figures illustrating, among other things, the ratio of the premium (I.E.,
purchase price in excess of book value) to deposits, purchase price to book
value, and purchase price to previous year's earnings.

    The figures for all banks acquired in the California Acquisitions
produced: (a) a median percentage of premium to deposits of 6.50%; (b) a median
ratio of purchase price to book value of 1.63; and (c) a median ratio of
purchase price to previous year's earnings of 17.10. The figures for 10 banks
acquired in California since 1996 that were approached on a merger of equals
basis produced: (a) a median percentage of premium to deposits of 6.57%; (b) a
median ratio of purchase price to book value of 1.49; and (c) a median ratio of
purchase price to previous year's earnings of 16.37.

    In comparison, assuming that the Exchange Ratio to be paid in the
Merger equals $22.86 per share (using a value for Americorp of $33.00 per share)
recent trades for Americorp stock have been $34.00 per share, Findley determined
that the Exchange Ratio in the Merger represented a percentage of premium to
deposits of 6.17%, a ratio of purchase price to book value of 1.68 and a ratio
of purchase price to 1997 earnings of 15.23.

    No other company or transaction used in the above analysis as a
comparison is identical to CIB, Americorp or the Merger. Accordingly, an
analysis of the results of the foregoing is not mathematical; rather, it
involves complex considerations and judgments concerning differences in
financial and operating characteristics of the companies and other factors that
could affect the public trading value of the companies to which Americorp, CIB
and the Merger are being compared.

    COMPARABLE COMPANY ANALYSIS. Using public and other available 
information, Findley compared certain financial ratios of CIB and Americorp 
(including the ratio of net income to average total assets 
["return on average assets"], the ratio of net income to average total equity 
["return on average equity"], the ratio of average equity to average assets 
and certain credit ratios for the year ended December 31, 1997 and the 
interim period ending March 30, 1998) to a peer group consisting of 20 
selected banks located in California. No company used in the analysis is 
identical to CIB or Americorp/ACB. The analysis necessarily involved complex 
considerations and judgments concerning differences in financial and 
operating characteristics of the companies. The results of this analysis 
indicated that CIB performed slightly ahead of peer group level on the basis 
of profitability in 1997 and Americorp/ACB performed slightly below peer 
group levels on the basis of profitability in 1997. CIB's return on average 
assets and return on average equity for 1997 were above peer group levels, 
inclusive of its interest spread factors (interest earned on assets minus 
interest paid on liabilities). CIB's performance in 1997, continuing through 
March 31, 1998, showed better than peer group levels concerning 
non-performing assets. CIB's non-interest expense, inclusive of payroll 
expense, quarters expense and other related non-interest expenses were higher 
than peer group level. Americorp/ACB return on average assets, return on 
average equity for 1997 was slightly below peer group levels. In addition, 
delinquent loans and non-performing loans were higher than peer group levels. 
Under the terms of the Merger, which requires a proportionate representation 
on the Board of Directors of outside Directors of Americorp/ACB after 
consummation of the transaction, the combined entity will be on an average 
with peer group performance with regard to return on average assets, return 
on average equity and other non-performing asset figures. Under the 
transaction, the Exchange Ratio is based upon the book value per share of CIB 
and Americorp on the Determination Date, taking into consideration fully 
funded loan loss reserves and other appropriate reserves and expenses that 
are required for this transaction.

    The foregoing summarizes the material portions of Findley's report, but
does not purport to be a complete description of the presentation by Findley to
CIB's Board of Directors or of the analyses performed by Findley. The
preparation of a fairness opinion is not necessarily susceptible to partial
analysis or summary description. Findley believes that its analyses and the
summary set forth above must be considered as a whole and that selecting a
portion of its analyses and of the factors considered, without considering all
analyses and factors would create an incomplete view of the process underlying
the analyses set forth in its presentation to the CIB Board of Directors.

    In performing its analyses, Findley made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Americorp or CIB. The
analyses performed by Findley are not necessarily indicative of actual values or
actual future results, which may be significantly more or less favorable than
suggested by such analyses. Such analyses were prepared solely as part of
Findley's analysis of the fairness, from a financial standpoint, of the Merger
to CIB's shareholders and were provided to the CIB Board of Directors in
connection with the delivery of Findley's opinion. The analyses do not purport
to be appraisals or to reflect the prices at which any securities may trade at
the present time or at any time in the future. Findley used in its analyses
various projections of future performance prepared by the management of CIB. The


                                      53

<PAGE>

projections are based on numerous variables and assumptions which are
inherently unpredictable and must be considered not certain of occurrence as
projected. Accordingly, actual results could vary significantly from those
set forth in such projections.

    In rendering its Fairness Opinion, Findley relied upon and assumed
without independent verification the accuracy and completeness of all of the
financial and other information reviewed by Findley for purposes of its
opinion. Findley did not make an independent evaluation or appraisal of the
assets and liabilities of Americorp, CIB or any of their respective
subsidiaries. CIB did not impose any limitations or restrictions with respect
to the scope of Findley's investigation or the procedures or methods it
followed, or with regard to any other matters relating to Findley's rendering
of the opinion regarding the fairness of the Merger. The Findley Group did
not participate in negotiations regarding the Agreement.

    CIB's Board of Directors selected and instructed Findley to render an
opinion with respect to the fairness of the Merger to CIB's shareholders from a
financial perspective based on its belief that Findley is experienced and
qualified in such matters. Findley has extensive experience in the evaluation of
banks in connection with mergers and acquisitions, and valuations for corporate
and other purposes. In over 40 years of bank consulting, Findley has been
involved in the creating, developing, merging and acquisition of hundreds of
financial institutions.

    Pursuant to the Engagement Letter, CIB agreed to pay Findley a fee of
$15,000 for Findley's services rendered to CIB in connection with the fairness
opinion plus expenses. CIB has agreed to indemnify Findley against certain
liabilities and expenses in connection with its services as financial advisor to
CIB. ACB has also agreed to pay Findley a fee of up to $2,000 plus expenses for
Findley's services to ACB in connection with the FDIC Application.

    EXCHANGE RATIO

    The issued and outstanding shares of Americorp Stock at the
Effective Time will remain outstanding (other than shares as to which
statutory dissenters' rights are perfected).

    Other than shares as to which statutory dissenters' rights are
perfected, each share of CIB Stock issued and outstanding immediately prior to
the Effective Time will automatically, without any action on the part of the
holder thereof, be canceled and converted into the right to receive a number of
shares of Americorp Stock as determined by the Exchange Ratio established in the
Agreement.

    The Exchange Ratio (i.e. the number of shares of Americorp Stock into
which a share of CIB Stock will be converted) will be computed by dividing the
CIB Book Value Per Share by the Americorp Book Value Per Share. Book Value Per
Share for the respective Parties will be determined as of the month end
preceding the Effective Time by dividing such Party's aggregate book value by
its number of shares outstanding on such date. "Aggregate Book Value" is a
Party's stockholders' equity on such date determined in accordance with
generally accepted accounting principles except (A) as otherwise provided in the
Agreement, (B) such amount will not be reduced by Merger related expenses, and
(C) the allowance


                                      54

<PAGE>

for loan and lease losses shall be increased by any impairment in the
allowance. Any impairment in the allowance will be determined in accordance
with generally accepted accounting principles and applicable bank regulatory
requirements.

    The exact amount of the Exchange Ratio is dependent, in part, upon
future results and, therefore, presently can not be determined. By way of
illustration only, if the respective Book Values Per Share had been
determined on June 30, 1998 and without any adjustment as permitted in the
Agreement, Americorp's Book Value Per Share would have been $20.02, CIB's
Book Value Per Share would have been $13.96 and the Exchange Ratio would have
been 0.6973 shares of Americorp Stock for each share of CIB Stock. THE ACTUAL
EXCHANGE RATIO MAY BE HIGHER OR LOWER THAN THE PRECEDING PRO FORMA
ILLUSTRATION.

    If the Parties can not agree on the respective amounts of Book Value
Per Share, the Exchange Ratio or any adjustments to the foregoing (including the
amount of impairment to any Party's allowance for loan losses), the Parties
shall attempt to agree upon the amount in dispute within seven days. If no
mutual agreement is reached within said period, the Parties shall immediately
hire an independent expert qualified to render an opinion regarding the amount
of the particular matter in dispute. The Parties shall cooperate fully with any
such independent expert and will equally split the cost of such expert. The
opinion of such expert shall be binding on the Parties for purposes of the
Agreement.

    The amount of adjustment, if any, to the respective Book Values Per
Share cannot currently be predicted.

    FRACTIONAL SHARES

    No fractional shares of Americorp Stock will be issued in the
Merger. In lieu thereof, each holder of CIB Stock who would otherwise be
entitled to receive a fractional share will receive an amount in cash equal
to the product (calculated to the nearest ten thousandth) obtained by
multiplying (a) the Americorp Book Value Per Share times (b) the fraction of
the shares of Americorp Stock to which such holder would otherwise be
entitled. No such holder shall be entitled to dividends or other rights in
respect of any such fraction.

    EFFECTIVE TIME OF MERGER

    The Effective Time shall occur on the day that the Agreement of Merger
(which is Exhibit A to the Agreement) is filed with the DFI after having been
previously filed with the Secretary with the DFI's approval endorsed thereon in
accordance with the provisions of the California Financial Code. The Effective
Time shall occur following the last to occur of (i) receipt of all necessary
regulatory approvals with the expiration of any applicable regulatory waiting
periods and (ii) satisfaction of the other conditions precedent set forth in the
Agreement. See "Conditions to the Merger." It is anticipated that the Effective
Time will occur sometime during the fourth quarter of 1998 or in early 1999. In
no event shall the Effective Time be later than March 31, 1999 unless a later
date is agreed to by the Parties.

    MANAGEMENT AND OPERATIONS OF AMERICORP AND ACB AFTER THE MERGER

    At the Effective Time, CIB will be merged with and into ACB and its
separate corporate existence will terminate.

    The number of directors of Americorp at the Effective Time will be
increased to nine and Allen W. Jue, Robert J. Lagomarsino, Gerald J.
Lukiewski, E. Thomas Martin, Harry L. Maynard (all of whom are from Americorp
and ACB), Michael T. Hribar, Edward F. Paul, Joseph L. Priske and Jacqueline
S. Pruner (all of whom are from CIB) will serve as the Board of Directors of
Americorp and ACB after the Merger until their successors have been chosen
and qualified in accordance with applicable law. Messrs Jue, Lagomarsino,
Paul and Priske will serve as the executive committee of Americorp and ACB
after the Merger. After the Merger, the principal officers of Americorp and
ACB will be Allen W. Jue (the current chairman of Americorp/ACB), who will
serve as chairman of the board, Joseph L. Priske (the current chairman of
CIB), who will serve as Vice Chairman, and Gerald J. Lukiewski (the current
president and chief executive officer of Americorp/ACB), who will serve as
president and chief executive officer. Thomas E. Anthony (the current Senior
Vice President/Chief Lending Officer of CIB), Allen R. Partridge (the current
Senior Vice President/Chief Financial Officer of CIB) and Mary Martha Stewart
(the current Senior Vice President/Chief Operating Officer of ACB) will serve
as the Chief Lending Officer, Chief Financial Officer and Chief Operating
Officer, respectively, of ACB after the Merger. Joseph L. Priske will also
serve as chairman of ACB's loan committee.

    The Articles of Incorporation and Bylaws of Americorp (except as
otherwise noted above) will continue to govern the business and affairs of
Americorp after the Merger until amended or repealed in accordance with
applicable law. The Articles of Incorporation and Bylaws of ACB will continue
to govern the business and affairs of ACB after the Merger until amended or
repealed in accordance with applicable law except the head office of ACB will
be relocated to the current head office location of CIB.

   
         Based on the combined bank's assets of approximately $226 million, 
the projected pro forma amount of annual net income has been estimated to be 
$2,235,000 after expenses for the Merger and integration costs, have been 
absorbed.  This net income amount takes into account expected initial cost 
savings of an estimated $637,000 and enhanced revenues of an estimated 
$139,000.  The cost savings are derived from a reduced level of personnel, 
decreased costs of employee benefits per employee and other reduced 
operational expenses on a combined basis.  Revenue enhancements are derived 
from increased lending activity due to the increased lending limits.  Net of 
taxes, the net improvement of net income would be approximately $458,000.  
The projected proforma earnings per share is estimated to be $2.31 using the 
number of shares outstanding as of June 30, 1998, with CIB's shares 
outstanding exchanged on a .7000 to 1.000 Exchange Ratio.  This compares to 
an annualized proforma basic earnings per share calculated as of June 30, 
1998 of $1.88.
    
   
         This information should be read in conjunction with the historical 
consolidated financial statements of CIB and Americorp, including their 
respective notes thereto, which are included in this Joint Proxy 
Statement/Prospectus, and in conjunction with the combined condensed 
historical selected financial data and other pro forma combined financial 
information appearing elsewhere in this Joint Proxy Statement/Prospectus.  
The cost savings and revenue enhancements reflected above and in this Joint 
Proxy Statement/Prospectus may not be indicative of the results that may be 
achieved in the future.  Assuming consummation of the Merger, the actual cost 
savings and revenue enhancement that may be realized in the Merger may 
differ, perhaps significantly, from the amounts reflected above and in this 
Joint Proxy Statement/Prospectus due to a variety of factors, including 
expected growth of the combined bank.  See "UNAUDITED PRO FORMA COMBINED 
FINANCIAL STATEMENT."
    

    AMENDMENT TO BYLAWS OF AMERICORP

    Shareholder approval of the principal terms of the Agreement and the
transaction contemplated thereby includes the approval of an amendment to the
Americorp bylaws to expand the number of its authorized directors at the
Effective Time and the election of Messrs. Lukiewski, Hribar, Paul and Priske
and Ms. Pruner as directors of Americorp. See "Management and Operations of
Americorp and ACB After the Merger". In order to effect such expansion,
shareholder approval of the principal terms of the Agreement and the
transaction contemplated thereby will also include approval of an amendment
to the first two sentences of Section 4.2(a) of the Americorp bylaws to read
as follows:

         "4.2  Number, Election, Qualification and Term of Office of
              Directors

               (a) Number. The number of Directors of this Corporation
               shall be not fewer than seven (7) nor more than thirteen
               (13), the exact numnber


                                      56

<PAGE>

               within such range to be fixed by the Board of Directors or
               the Shareholders of the Corporation from time to time.  Until
               changed, the exact number of Directors shall be nine (9)."

If for any reason the Merger is not carried out, the amendment to the bylaws
will not become effective.

    REGULATORY APPROVALS

    The consummation of the Merger is subject to various conditions,
including, among others, receipt of the prior approvals of the DFI and the
FDIC.

    The Agreement provides that the obligations of the Parties to
consummate the Merger are conditioned upon all regulatory approvals having
been granted by March 31, 1999 without the imposition of conditions which, in
the opinion of Americorp would materially adversely effect the financial
condition or operations of any Party or otherwise would be burdensome.

    Applications for regulatory review and approval of the Merger and
the related transactions have been filed. There can be no assurance that the
DFI and the FDIC will approve or take other required action with respect to
the Merger and the related transactions or as to the date of such approvals
or action.

    In determining whether to approve the Merger, the DFI will consider
factors such as (i) the effects of the Merger on competition; (ii) the
effects of the Merger on the convenience and needs of the communities to be
served; (iii) the financial condition of ACB; (iv) whether the Merger is fair
and reasonable to the depositors, creditors and shareholders of Americorp,
ACB and CIB; (v) the competence, experience and integrity of ACB's
management; and (vi) whether the Merger is fair, just and equitable to
Americorp, ACB and CIB.

    In determining whether to approve the Merger, the FDIC will consider
factors such as (i) the financial condition, competence, experience and
integrity of ACB's management; and (ii) the effect of the Merger on
competition.

    INTERESTS OF CERTAIN PERSONS IN THE MERGER

    As a condition to the Merger, each of the directors of the respective
Parties has entered into an agreement whereby each has agreed to (i) vote his or
her shares of Stock in favor of approving the principal terms of the Agreement
and the transactions contemplated thereby, (ii) recommend, subject to his or her
fiduciary duty, to the Party's shareholders to vote in favor of the Agreement,
(iii) not dispose, subject to certain exceptions, of his or her shares of Stock,
and (iv) cooperate fully with the other Parties in connection with the Merger.

    Under these agreements the respective directors of CIB and Americorp
have agreed to vote their respective shares (approximately ___% of the
outstanding shares in the case of CIB Stock and


                                      57


<PAGE>

approximately ___% of the outstanding shares in the case of Americorp Stock) 
to approve the principal terms of the Agreement, increasing the likelihood 
that the Merger will be approved. The affirmative vote of the holders of an 
additional ___% (in the case of CIB) and ___% (in the case of Americorp) of 
the respective outstanding shares voting at the respective Meetings will be 
required in order to approve the Agreement.

     Messrs. Hribar, Paul and Priske and Ms. Pruner will be added as 
directors of Americorp and ACB at the Effective Time. Messrs. Paul and Priske 
will also serve on the executive committee of Americorp and ACB. Mr. Priske, 
the current Chairman of CIB, will be elected as Vice Chairman of Americorp 
and ACB and will be chairman of ACB's loan committee.

     The officers and employees of CIB at the Effective Time will become 
officers and employees of ACB subject to the policies of ACB, will be 
entitled to participate in all employee benefits and benefit programs of ACB 
on the same basis as similarly situated employees of ACB and will be credited 
for eligibility, participation and vesting purposes with their respective 
years of past service with CIB.

     Pursuant to the Agreement, a committee has been established to 
determine, among other things, a personnel, salary and benefits structure for 
ACB after the Merger and to fix the amount of severance to be paid to 
officers and employees of the Parties displaced by the Merger. The committee 
is composed of Gerald J. Lukiewski (on behalf of Americorp) and Joseph L. 
Priske and Jacqueline Pruner (on behalf of CIB). The amount of severance 
benefits has not yet been determined by the committee.

     ACB has also agreed to honor certain employment agreements for CIB's 
Senior Lending Officer and Chief Financial Officer. For a description of such 
agreements, see "BUSINESS OF CIB - Executive Compensation." Messrs. Anthony 
and Partridge will become the Chief Lending Officer and the Chief Financial 
Officer of ACB after the Merger.

     Subject to the receipt of any required consents, a new stock option plan 
will be adopted by Americorp in order for each person who is an officer or 
employee of CIB and who will continue with ACB after the Merger, and for each 
director of CIB, who does not exercise his stock option to have the right to 
receive a substitute stock option from Americorp on a fully vested basis.

     CIB's directors' and officers' liability insurance will have its 
discovery period extended for 36 months with respect to all matters arising 
from facts or events which occurred before the Effective Time for which CIB 
would have had an obligation to indemnify its directors and officers.

     In connection with the three current directors of CIB and the two 
current directors of Americorp who will resign at the time of the Merger, it 
is anticipated that ACB will enter into consulting agreements with such 
persons in order for them to continue to provide services and guidance to 
Americorp and ACB after the Merger. It is anticipated that Catherine S. Wood 
and Lincoln E. Cryne, (directors of Americorp and ACB) will receive aggregate 
payments of $33,000 and $68,000, respectively, pursuant to their consulting 
agreements and that Fred G. Buenger, William Burke and Glenn Farr (directors 
of CIB) will

                                      58

<PAGE>

receive $33,000, $33,000 and $4,500, respectively, pursuant to their 
consulting agreements.

     ADDITIONAL AGREEMENTS

     In addition to the directors agreements described in "Interests of 
Certain Persons in the Merger," the directors and certain other affiliates of 
each of the Parties have entered into agreements restricting such persons' 
ability to sell shares of Stock which such person has acquired or may acquire 
in connection with the Merger except in accordance with such agreements.

   
     FEDERAL INCOME TAX CONSEQUENCES
    
     The Parties have not requested a ruling from the Internal Revenue 
Service in connection with the Merger. The following is a summary of the 
opinion of Vavrinek, CIB's independent auditors, that CIB and Americorp 
received concerning the material federal income tax consequences resulting 
from the Merger. Consummation of the Merger is conditioned upon receipt by 
CIB and Americorp of such opinion prior to the date of this Joint Proxy 
Statement/Prospectus. The following is based upon applicable federal law and 
judicial and administrative interpretations on the date hereof, any of which 
is subject to change at any time and representations from the management of 
CIB, Americorp and ACB.

         (i)    The Merger will qualify as a reorganization under Section 368 
     of the Internal Revenue Code of 1986, as amended (the "Code"), and CIB, 
     Americorp and ACB each will be a "party to a reorganization" within the 
     meaning of Section 368(b) of the Code.

         (ii)   No gain or loss will be recognized by any of the Parties as a 
     result of the Merger.

         (iii)  No gain or loss will be recognized by a shareholder of CIB on 
     the receipt solely of Americorp Stock in exchange for his shares of CIB 
     Stock.

         (iv)   The tax basis of the assets in ACB after the merger will be 
     the same as the tax basis of the assets held by CIB and ACB immediately 
     before the Merger.

         (v)    The holding period of Americorp Stock to be received in the 
     Merger by a CIB shareholder will include the holding period of shares of 
     CIB Stock exchanged therefor, provided that the shares of CIB Stock are 
     held as capital assets at the Effective Time.

         (vi)   The tax basis of Americorp Stock to be received in the Merger 
     by CIB shareholders will be the same as the basis of the sharers of CIB 
     Stock surrendered in exchange therefor, decreased by the amount of basis 
     allocated to any cash received in lieu of fractional shares that are 
     hypothetically received by the CIB shareholders and redeemed for cash.

                                      59

<PAGE>


        (vii) The payment of cash to shareholders of CIB in lieu of
     fractional share interest of Americorp Stock will be treated as if the
     fractional shares were distributed as part of the exchange and them
     redeemed by Americorp. These cash payments will be treated as having been
     received as a distribution in redemption of that fractional share interest
     subject to the conditions and limitations of Section 302 of the Code. If a
     fractional share of Americorp Stock would constitute a capital asset in the
     hands of a redeeming shareholder, any resulting gain or loss will be
     characterized as a capital gain or loss in accordance with the provisions
     and limitations of Subchapter P of Chapter 1 of the Code.

         (viii) No gain or loss will be recognized for federal income tax 
     purposes by the holders of outstanding stock options granted under CIB's 
     stock option plan as a result of the granting of substitute options 
     pursuant to Americorp's stock option plan.

         (ix)   The granting of any substitute stock option to a holder of a 
     CIB stock option will not be deemed a modification of an incentive stock 
     option.

     The opinion of Vavrinek summarized above is not binding on the Internal 
Revenue Service, which could take positions contrary to the conclusions in 
such opinion.

     The exchange of Americorp Stock or CIB Stock for cash pursuant to the 
exercise of dissenters' rights will be a taxable transaction. Holders of 
Americorp Stock or CIB Stock electing to exercise dissenters' rights should 
consult their own tax advisers as to the tax treatment in their particular 
circumstances. See "Dissenting Shareholders' Rights."

    DUE TO THE INDIVIDUAL NATURE OF THE TAX CONSEQUENCES OF THE MERGER, 
IT IS RECOMMENDED THAT CIB AND AMERICORP SHAREHOLDERS CONSULT THEIR OWN TAX 
ADVISORS CONCERNING THE TAX CONSEQUENCES OF THE MERGER (INCLUDING THE 
APPLICATION AND EFFECT OF STATE AND LOCAL INCOME AND OTHER TAX LAWS).

    EXCHANGE PROCEDURES

    As soon as practicable after the Effective Time, the exchange agent to be 
designated by the Parties (the "Exchange Agent") will mail to each holder of 
record of outstanding shares of CIB Stock a letter of transmittal which is to 
be used by each CIB shareholder to return to the Exchange Agent the stock 
certificates representing the CIB Stock owned by him (the "Old 
Certificates"), which certificates should be duly endorsed in blank by such 
CIB shareholder. As soon as practicable after receiving such Old Certificates 
from a CIB shareholder together with the duly executed letter of transmittal 
and any other items specified by the letter of transmittal, the Exchange 
Agent will deliver to such CIB shareholder new certificates ("New 
Certificates") representing the appropriate number of shares of Americorp 
Stock, together with checks for payment of cash in lieu of fractional shares. 
No dividends or other distributions that are declared on Americorp Stock will 
be paid to persons otherwise entitled to receive the same until the Old 
Certificates have been surrendered in exchange for New Certificates, but upon 
such surrender, such dividends or other distributions, from and after the 
Effective Time, will be paid to such persons in accordance with the terms of 
Americorp Stock. No interest will be paid to the CIB shareholders on the

                                       60

<PAGE>

cash or the value of the Americorp Stock into which their shares of CIB Stock 
will be exchanged.

    CIB SHAREHOLDERS SHOULD NOT SEND IN THEIR STOCK CERTIFICATES UNTIL 
THEY RECEIVE THE LETTER OF TRANSMITTAL FORM AND INSTRUCTIONS.

     SALES OF AMERICORP STOCK

     The shares of Americorp Stock to be issued to shareholders of CIB in the 
Merger have been registered under the Securities Act. Such shares will be 
freely transferable under the Securities Act, except for shares issued to any 
person who may be deemed to be an "affiliate" of CIB within the meaning of 
Rule 145 under the Securities Act.

     NASDAQ LISTING

     The Parties have agreed that following the Effective Time, consideration 
will be given to listing the shares of Americorp Stock on Nasdaq with the 
intent to so list such shares during the first full year of operations. 
However, no assurance can be given that such application will be filed or 
that the shares of Americorp Stock will become so listed.

     ACCOUNTING TREATMENT

     The Parties anticipate that the Merger will be treated as a pooling of 
interests for accounting purposes. Prior to the Effective Time and as a 
condition precedent to the closing, the respective accounting firms of the 
Parties will confirm in writing the accounting treatment of the Merger as a 
pooling of interest. The unaudited pro forma financial information contained 
in this Joint Proxy Statement/Prospectus has been prepared using the pooling 
of interest accounting method to account for the Merger. See "UNAUDITED PRO 
FORMA COMBINED FINANCIAL STATEMENTS."

     CONDITIONS TO THE MERGER

     The obligation of each of the parties to consummate the Merger is 
subject to the satisfaction or waiver on or before the Effective Time of, 
among other things, the following conditions: (i) the Agreement and the 
transactions contemplated thereby will have received all requisite approvals 
of the shareholders and Boards of Directors of CIB, ACB and Americorp; (ii) 
no judgment, decree, injunction, order or proceeding will be outstanding or 
threatened by any governmental entity which prohibits or restricts the 
effectuation of, or threatens to invalidate or set aside the Merger 
substantially in the form contemplated by the Agreement unless counsel to the 
Party against whom such action or proceeding was instituted or threatened 
renders to the other Parties a favorable opinion that such judgment, decree, 
injunction, order or proceeding is without merit; (iii) by March 31, 1999, 
all approvals or consents of any applicable governmental agency will have 
been obtained or granted for the Merger and the transactions contemplated by 
the Agreement (in each case either unconditionally or without the imposition 
of conditions or

                                       61

<PAGE>

limitations that are applicable to any Party or would become applicable to 
Americorp or ACB after the Merger that Americorp reasonably and in good faith 
concludes would materially adversely affect the financial condition or 
operations of any Party or otherwise would be materially burdensome to any 
Party) and the applicable waiting period under all laws will have expired; 
(iv) the Registration Statement shall have been declared effective by the SEC 
and shall not be the subject of any stop order or proceedings seeking or 
threatening a stop order; (v) Americorp shall have received all state 
securities permits and other authorizations necessary to issue the Americorp 
Stock to consummate the Merger; (vi) CIB and Americorp will have received an 
opinion reasonably satisfactory to CIB and Americorp from Vavrinek to the 
effect that the Merger will not result in the recognition of gain or loss for 
federal income tax purposes, nor will the issuance of Americorp Stock result 
in the recognition of gain or loss to holders of CIB Stock who receive 
Americorp Stock in the Merger (see "- Certain Federal Income Tax 
Consequences"); (vii) the Parties' respective accounting firms will have 
confirmed in writing to CIB and Americorp that the Merger will quality for 
pooling of interests accounting treatment (see "-Accounting Treatment"); and 
(viii) all third party consent necessary to permit the parties to consummate 
the Merger will have been obtained except under certain circumstances.

     NONSOLICITATION

     Under the terms of the Agreement, Americorp and CIB have each agreed not 
to solicit, initiate or encourage any "Competing Transaction" (as hereinafter 
defined). In addition, each has agreed (unless it determines, with advice of 
counsel, that its fiduciary duty requires otherwise) not to participate in any

                                       62

<PAGE>

negotiations or discussions regarding, or furnish any information with 
respect to, or otherwise cooperate in any way in connection with, any effort 
or attempt to effect any Competing Transaction with or involving any person 
other than a Party unless it receives a bona fide offer from a person other 
than the Parties to the Agreement and subject to fiduciary obligations. Each 
Party has agreed to promptly notify the other party of the terms of any 
proposal which it may receive in respect of any Competing Transaction. The 
term "Competing Transaction" means any of the following: a merger, 
consolidation, share exchange or other business combination; a sale, lease, 
exchange, mortgage, pledge, transfer or other disposition of assets 
representing 10% or more of Americorp's or of CIB's assets; a sale of shares 
of capital stock (or securities convertible or exchangeable into or otherwise 
evidencing, or any agreement or instrument evidencing, the right to acquire 
capital stock), representing 10% or more of the voting power; a tender offer 
or exchange offer for at least 10% of the outstanding shares; a solicitation 
of proxies in opposition to approval of the Merger by shareholders; or a 
public announcement of an unsolicited bona fide proposal, plan or intention 
to do any of the foregoing.

     Failure to act or refraining from doing any act in certain circumstances 
by a Party in connection with a Competing Transaction will result in the 
other Party having the right to terminate the Agreement. If the Agreement 
were to be so terminated and the Party involved in the Competing Transaction 
enters into an agreement for a Competing Transaction prior to the termination 
of the Agreement or during the 12 month period immediately following the 
termination, such Party will be obligated to pay the other Party $750,000 
which amount represents (i) direct costs and expenses (including, but not 
limited to, fees and expenses of financial or other consultants, printing 
costs, accountants and counsel) incurred in negotiating and undertaking to 
carry out the transactions contemplated by the Agreement, including 
management time devoted to negotiation and preparation for the transactions 
contemplated by the Agreement; (ii) indirect costs and expenses incurred in 
connection with the transactions contemplated by the Agreement; and (iii) 
loss as a result of the transactions contemplated by the Agreement not being 
consummated

     EXPENSES

     If the Agreement is terminated by Americorp or ACB because CIB's 
shareholders fail to approve the Merger, or because CIB fails to satisfy 
certain of its obligations under the Agreement, CIB will be obligated to pay 
all of Americorp's expenses incurred in connection with the Merger 
transaction, not to exceed $150,000.

     If the Agreement is terminated by CIB because Americorp's shareholders 
fail to approve the Merger, or because Americorp fails to satisfy certain of 
its obligations under the Agreement, Americorp will be obligated to pay all 
of CIB's expenses incurred in connection with the Merger transaction, not to 
exceed $150,000.

     TREATMENT OF STOCK OPTIONS

     At the Effective Time, the CIB stock option plan will terminate, the 
current Americorp stock option plan will also be terminated (but not the 
options granted thereunder) and a new stock option plan

                                       63

<PAGE>

will be adopted by Americorp in connection with the Merger (the "1998 Plan"). 
See "INFORMATION CONCERNING AMERICORP MEETING ONLY."

     At and as of the Effective Time, Americorp shall grant substitute stock 
options pursuant to the 1998 Plan to each and every officer, employee and 
director of CIB who has at the Effective Time an outstanding option to 
purchase shares of CIB Stock ("CIB Stock Options"). Each and every substitute 
stock option so granted by Americorp pursuant to the Americorp stock option 
plan to replace an CIB Stock Option shall retain the "vesting" schedule 
reflected in each of the respective stock option agreements and shall be 
exercisable for that number of whole shares of Americorp Stock equal to the 
product of (A) the number of shares of CIB Stock that were purchasable under 
such CIB Stock Option immediately prior to the Effective Time multiplied by 
(B) the Exchange Ratio, rounded down to the nearest whole number of shares of 
Americorp Stock. Further, each and every substitute stock option so granted 
shall provide for a per share exercise price which shall be equal to the 
quotient determined by dividing (A) the exercise price per share of CIB Stock 
at which such CIB Stock Option was exercisable immediately prior to the 
Effective Time by (B) the Exchange Ratio.

     TERMINATION

     The Agreement may be terminated at any time prior to the Effective Time 
(i) by mutual consent of CIB and Americorp in writing; (ii) by CIB or 
Americorp if any material breach or default by the other Party is not cured 
within 20 business days after notice thereof; (iii) by CIB or Americorp if 
any governmental or regulatory consent is not obtained by March 31, 1999 or 
if any governmental or regulatory authority denies or refuses to grant any 
approval, consent or authorization required to be obtained to consummate the 
transactions contemplated by the Agreement unless, within 20 business days 
after such denial or refusal, all parties agree to resubmit the application 
to the regulatory authority that has denied or refused to grant the approval, 
consent or qualification requested; (iv) by Americorp if any of the 
conditions to its performance of the Agreement shall not have been met, or by 
CIB if any of the conditions to its performance of the Agreement shall not 
have been met, by March 31, 1999, or such earlier time as it becomes apparent 
that such conditions shall not be met; or (v) if a Party shall have failed to 
act or refrained from doing any act relating to a Competing Transaction.

Parties from accounting for the business combination to be effected by the
Merger as a pooling of interests; (xvii) sell any investment security prior
to maturity, except in the ordinary course of business; or (xviii) grant,
renew or commit to grant or renew any extension of credit if such extension

certain exceptions; (xix) purchase, redeem or otherwise acquire any of its
securities or any rights, options or securities to acquire its equity
securities; (xx) change any of its basic policies and practices relating to
certain specified matters; or (xi) settle any claim, action or proceeding
involving any material liability for monetary damages or enter into any
settlement agreement containing material obligations.

         The Agreement also provides that each Party will (i) use its best
efforts to take, or cause to be taken, all actions and to do, or cause to be
done, all things necessary, proper or advisable under applicable laws and

promptly as practical; (ii) obtain the consent of the other Party before it

has had or may reasonably be expected to have a materially adverse effect on
the financial condition, operations, business or properties; (iv) provide
access to the other Party of certain information: and (v) use its reasonable
efforts between the date of the Agreement and the Effective Time to take all
actions necessary or desirable, including the filing of any regulatory
applications.

         Subject to applicable law: (i) the Agreement may be amended at any
time by the action of the Boards of Directors of CIB, ACB and Americorp
without action by their shareholders pursuant to a writing signed by all
parties to the Agreement; and (ii) the Parties, by action of their respective
Boards of Directors, may, at any time prior to the Effective Time, extend the
performance of any obligation or action required by the Agreement, waive
inaccuracies in representations and warranties and waive compliance with any
agreements or conditions for their respective benefit contained in the
Agreement.

         DISSENTING SHAREHOLDERS' RIGHTS

         CIB

         Shareholders of CIB will be entitled to exercise dissenters' rights
in connection with the Merger.

         AMERICORP

         Shareholders of Americorp will also be entitled to exercise
dissenters' rights in connection with the Merger.

         PROCEDURES

         Each holder of shares of Americorp Stock or CIB Stock that were
outstanding as of the respective Record Dates and remain outstanding at the
Effective Time who does not vote such shares in favor of the proposal to
approve the Merger by complying with the procedures set forth in Chapter 13
of the California General Corporation Law ("Chapter 13 of the California
Law") will be entitled to receive an amount equal to the fair market value of
his or her shares as of July 7, 1998, the day before the public announcement
of the Merger. The final bid price for Americorp Stock on July 6, 1998 was
$32.00. The Findley Opinion dated July 9, 1998 concluded that the fair market
value of CIB Stock on July 6, 1998 was $19.50. A copy of Chapter 13 of the
California Law is attached hereto as Appendix D and should be read for more
complete information concerning dissenters' rights. THE REQUIRED PROCEDURE
SET FORTH IN CHAPTER 13 OF THE CALIFORNIA LAW MUST BE FOLLOWED EXACTLY OR ANY
DISSENTERS' RIGHTS MAY BE LOST. The information set forth below is a general
summary of dissenters' rights as they apply to Americorp and CIB shareholders
and is qualified in its entirety by reference to Appendix D.


                                       66
<PAGE>

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

         If the Merger is approved by the shareholders, Americorp and CIB
will each have 10 days after the respective approvals to send to those
shareholders who did not vote in favor of the Merger written notice of such
approval accompanied by a copy of Chapter 13 of the California Law, a
statement of the price determined to represent the fair market value of the
dissenting shares as of July 6, 1998 and a brief description of the procedure
to be followed if a shareholder desires to exercise dissenters' rights.
Within 30 days after the date on which the notice of the approval of the
Merger is mailed, the dissenting shareholder must make written demand upon
Americorp or CIB, as the case may be, for the purchase of dissenting shares
and payment to such shareholder of their fair market value, specifying the
number of shares held of record by such shareholder and a statement of what
the shareholder claims to be the fair market value of those shares as of July
6, 1998, and must surrender, at the office designated in the notice of
approval, the certificates representing the dissenting shares to be stamped
or endorsed with a statement that they are dissenting shares or to be
exchanged for certificates of appropriate denomination so stamped or
endorsed. Any shares of Stock that are transferred prior to their submission
for endorsement lose their status as dissenting shares.

          If the Party and the dissenting shareholder agree that the
surrendered shares are dissenting shares and agree upon the price of the
shares, the dissenting shareholder will be entitled to the agreed price with
interest thereon at the legal rate on judgments from the date of the
agreement. Subject to the restrictions imposed under California law on the
ability of a Party to purchase its outstanding shares, payment of the fair
value of the dissenting shares shall be made within 30 days after the amount
thereof has been agreed upon or 30 days after any statutory or contractual
conditions to the Merger have been satisfied, whichever is later, subject to
the surrender of the certificates therefor, unless provided otherwise by
agreement.

         If the Party denies that the shares surrendered are dissenting
shares or the Party and the dissenting shareholder fail to agree upon a fair
market value of such shares, then the dissenting shareholder must, within six
months after the notice of approval is mailed, file a complaint in the
Superior Court of the proper county requesting the court to make such
determinations or intervene in any pending action brought by any other
dissenting shareholder. If the complaint is not filed or intervention in a
pending action is not made within the specified six-month period, the
dissenter's rights are lost. If the fair market value of the dissenting
shares is at issue, the court will determine, or will appoint one or more
impartial appraisers to determine, such fair market value.

         A dissenting shareholder may not withdraw his or her dissent or demand
for payment unless the


                                       67
<PAGE>

effected Party consents to such withdrawal.

         The Merger is not directly conditioned upon only a limited number of
shareholders of Americorp or CIB Stock having voted against the Merger or
otherwise having perfected dissenters' rights. Nevertheless, the payment of a
significant amount of cash pursuant to the exercise of dissenters' rights
would effect the ability of the Merger to be accounted for as a "pooling of
interest." The Merger is conditioned upon the respective accountants
confirming in writing that the accounting treatment for the Merger is a
pooling of interest (see "-Accounting Treatment").

1998 and the years ended December 31, 1997, 1996 and 1995. It should be read

notes thereto of Americorp and the historical financial statements and notes
thereto of CIB, which are included elsewhere in this Joint Proxy

account any adjustments as permitted by the Agreement. THE EXCHANGE RATIO
COULD BE HIGHER OR LOWER THAN .7000 TO 1.000.

purposes only and are not indicative of the operating results that would have
been achieved or the financial position that would have existed had the
Merger been consumated on the dates indicated in the preceding paragraph, nor
are they indicative of the future operating results or financial position of

                    DESCRIPTION OF CIB AND AMERICORP STOCK

         CIB is a California banking corporation organized under the laws of
the State of California, and the rights of CIB Shareholders are governed by
the California Financial Code, the California Corporations Code (the
"Corporations Code"), the Articles of Incorporation of CIB (the "CIB
Articles"), and the bylaws of CIB, as amended (the "CIB Bylaws"). Upon
consummation of the Agreement, the CIB Shareholders will become shareholders
of Americorp ("Americorp Shareholders"). As Americorp Shareholders, the
rights of the then former CIB Shareholders will be governed by Division 1,
Chapters 1 - 23 of the Corporations Code, other applicable California
statutes, the Articles of Incorporation of Americorp (the "Americorp
Articles"), and the bylaws of Americorp (the "Americorp Bylaws").

CIB STOCK

         CIB is authorized by the CIB Articles, as amended, to issue
5,000,000 shares of CIB Stock, without par value. At the CIB Record Date,

CIB Stock are entitled to one vote, in person or by proxy, for each share of
CIB Stock held of record in the shareholder's name on the books of CIB as of
the record date on any matter submitted to the vote of the shareholders,
except that in connection with the election of directors, the shares may be
voted cumulatively. Each share of CIB Stock has the same rights, privileges
and preferences as every other share and will share equally in CIB's net
assets upon liquidation or dissolution. CIB Stock has no conversion,
preemptive or redemption rights or sinking fund provisions.

         California law prohibits a California state-chartered bank from

therefor and after satisfaction of the prior rights of holders of outstanding
preferred stock, if any (subject to certain restrictions on payment of
dividends imposed by the General Corporation Law of California). See
"Dividend Restrictions."

         The transfer agent and registrar for Americorp Stock is Chase Mellon
Financial Services.

         DIFFERENCES BETWEEN RIGHTS OF HOLDERS OF AMERICORP STOCK AND CIB STOCK

         The following subsections discuss in detail the differences between
rights of holders of Americorp Stock and CIB Stock.

         CLASSIFICATION OF BOARD OF DIRECTORS

         CIB's Articles do not permit the CIB Board of Directors to be
divided into classes with any class having a term of office of longer than
one year. Each director of CIB must be elected annually. Americorp's Articles
and Bylaws also do not provide for a classified Board of Directors.

         VOTING RIGHTS

         See the description of voting rights contained in "CIB Stock" and
"Americorp Stock".

         NUMBER OF DIRECTORS

         Although the Corporations Code does not require Americorp or CIB to
maintain any specific range of number of directors, the number of directors
of Americorp and CIB may not be less than a stated minimum nor more than a
stated maximum (which in no case shall be greater than two times the stated
minimum minus one) with the exact number of directors to be fixed, within the
limits specified. The CIB Bylaws currently provide that the number of
directors on the CIB Board of Directors may not be fewer than 5 nor more than
9, and the current number of members on CIB's Board of Directors has been
fixed at 7. Americorp Bylaws currently provide that the number of directors
on Americorp Board of Directors may not be fewer than four nor more than
seven, and the current number of members on Americorp's Board of Directors
has been fixed at six at the present time.

         At the Effective Time of the Merger, (i) the number of directors for
Americorp will be increased to nine (9) and (ii) the Board will be
reconstituted to include the directors indicated in "THE MERGER - Management
and Operation of Americorp and ACB After the Merger.


                                      84
<PAGE>


         DIVIDEND RESTRICTIONS

         Since CIB is a state-chartered bank, its ability to pay dividends or
make distributions to its shareholders is subject to restrictions set forth
in the California Financial Code. The California Financial Code provides that
neither a bank nor any majority-owned subsidiary of a bank may make a
distribution to its shareholders in an amount which exceeds the lesser of (i)
the bank's retained earnings; or (ii) the bank's net income for its last
three fiscal years, less the amount of any distributions made by the bank or
by any majority-owned subsidiary of the bank to the shareholders of the bank
during such period. Notwithstanding the previous provision, a bank may, with
the prior approval of the Commissioner of Financial Institutions, make a
distribution to the shareholders of the bank in an amount not exceeding the
greatest of (a) its retained earnings; (b) its net income for its last fiscal
year; or (c) the net income of the bank for its current fiscal year. If the
Commissioner finds that the stockholders' equity of a bank is inadequate or
that the making of a distribution by a bank would be unsafe or unsound, the
Commissioner may order the bank to refrain from making a proposed
distribution.

         The ability of Americorp to pay cash dividends is limited by the
provisions of Section 500 of the California Corporations Code, which
prohibits the payment of dividends unless (i) the retained earnings of the
corporation immediately prior to the distribution exceeds the amount of the
distribution; (ii) the assets of the corporation exceed 1 1/4 times its
liabilities; or (iii) the current assets of the corporation exceed its
current liabilities, but if the average pre-tax earnings of the corporation
before interest expense for the two years preceding the distribution was less
than the average interest expense of the corporation for those years, the
current assets of the corporation must exceed 1 1/4 times its current
liabilities.

         The ability of Americorp to pay cash dividends is largely dependent
on cash dividends being paid to it by ACB. ACB has the same restrictions on
its ability to pay cash dividends as does CIB.

         DISSENTERS' RIGHTS

         Pursuant to the General Corporation Law of California, holders of
Americorp Stock would be entitled, subject to the provisions of Chapter 13,
to dissenters' rights in connection with any transaction which constitutes a
reorganization (as defined in Section 181 of the California Corporations
Code). See "THE MERGER - Dissenting Shareholders' Rights." However, pursuant
to the California Financial Code, shareholders of CIB Stock are not entitled
to dissenters' rights in connection with any transactions between two banking
institutions which constitutes a reorganization (as defined in Section 181 of
the California Corporations Code) where CIB is the corporation surviving such
transaction, even if dissenters' rights were otherwise available pursuant to
Chapter 13. Dissenters' rights are available to shareholders of CIB in the
Merger since CIB is not the surviving corporation in such merger.

         RESTRICTIONS ON ACQUISITION OF AMERICORP

         The following discussion is a summary of certain provisions of
California and Federal law and regulations and California corporate law, as well
as the Articles of Incorporation and Bylaws of


                                      85

<PAGE>


Americorp, which may be deemed to have "anti-takeover" effects. The
description of these provisions is necessarily general and reference should
be made to the actual law and regulations and to the Articles of
Incorporation and Bylaws of Americorp.

         CALIFORNIA AND FEDERAL BANKING LAW

         The Federal Change in Bank Control Act of 1978 prohibits a person or
group of persons "acting in concert" from acquiring "control" of a bank
holding company unless the Board of Governors of the Federal Reserve System
(the "Federal Reserve Board") has been given 60 days' prior written notice of
such proposed acquisition and within that time period the Federal Reserve
Board has not issued a notice disapproving the proposed acquisition or
extending for up to another 30 days the period during which such a
disapproval may be issued. An acquisition may be made prior to the expiration
of the disapproval period if the Federal Reserve Board issues written notice
of its intent not to disapprove the action. Under a rebuttable presumption
established by the Federal Reserve Board the acquisition of more than 10% of
a class of voting stock of a bank with a class of securities registered under
Section 12 of the Exchange Act, would, under the circumstances set forth in
the presumption, constitute the acquisition of control.

         Under the California Financial Code, no person shall, directly or
indirectly, acquire control of a California licensed bank or a bank holding
company unless the Commissioner has approved such acquisition of control. A
person would be deemed to have acquired control of Americorp under this state
law if such person, directly or indirectly, has the power (i) to vote 25% or
more of the voting power of Americorp or (ii) to direct or cause the
direction of the management and policies of Americorp. For purposes of this
law, a person who directly or indirectly owns or controls 10% or more of the
Americorp Stock would be presumed to control Americorp.

         In addition, any "company" would be required to obtain the approval
of the Federal Reserve Board under the Bank Holding Company Act of 1956, as
amended (the "BHC Act"), before acquiring 25% (5% in the case of an acquiror
that is, or is deemed to be, a bank holding company) or more of the
outstanding Americorp Stock of, or such lesser number of shares as constitute
control over, Americorp.

         ANTI-TAKEOVER PROVISIONS IN AMERICORP'S ARTICLES AND BYLAWS

         Americorp's Articles and Bylaws contain identical provisions that
deal with matters of corporate governance and certain rights of shareholders
relating to offers to acquire Americorp.

         These provisions authorize the Board of Directors to oppose a tender
or other offer for Americorp. When considering whether to oppose an offer,
the Board may consider any pertinent issue, including any or all of the
following: (A) whether the offer price is acceptable based upon the
historical and present operating results or financial condition of Americorp,
(B) whether a more favorable price could be obtained for Americorp's
securities in the future, (C) the impact which an acquisition of Americorp
would have on the employees, depositors and customers of Americorp and its
subsidiaries and the communities which they serve, (D) the reputation and
business practices of the offeror and its management and affiliates


                                      86

<PAGE>


as they would affect the employees, depositors, and customers of Americorp
and its subsidiaries and the communities which they serve and the future
value of Americorp stock, (E) the value of the securities (if any) which the
offeror is offering in exchange for Americorp's securities, based on an
analysis of the worth of Americorp as compared to the corporation or other
entity whose securities are being offered, and (F) any antitrust or other
legal and regulatory issues that raised by the offer.

         If the Board of Directors determines that an offer should be
rejected, it may take any lawful action to accomplish its purpose, including,
but not limited to, any or all of the following: advising shareholders not to
accept the offer; litigation against the offeror; filing complaints with all
governmental and regulatory authorities; acquiring Americorp's securities;
selling or otherwise issuing authorized but unissued securities or granting
options with respect thereto; acquiring a company to create an antitrust or
other regulatory problem for the offeror; and soliciting a more favorable
offer from another individual or entity.

         These provisions may have the effect of discouraging a future
takeover attempt which is not approved by the Board of Directors but which
individual Americorp stockholders may deem to be in their best interest or in
which stockholders may receive a substantial premium for their shares over
then current market prices. As a result, Americorp Shareholders who might
desire to participate in such a transaction may not have an opportunity to do
so.

         PURPOSE AND TAKEOVER DEFENSIVE EFFECTS OF AMERICORP'S ARTICLES AND
         BYLAWS

         The Board of Directors of Americorp believes that the provisions
described above are prudent and will reduce Americorp's vulnerability to
takeover attempts and certain other transactions which have not been
negotiated with and approved by its Board of Directors. The Board of
Directors believes these provisions are in the best interest of Americorp and
its stockholders. In the judgment of the Board of Directors, Americorp's
Board will be in the best position to determine the true value of Americorp
and to negotiate more effectively for what may be in the best interest of its
stockholders. Accordingly, the Board of Directors believes that it is in the
best interest of Americorp and its stockholders to encourage potential
acquirors to negotiate directly with the Board of Directors of Americorp and
that these provisions will encourage such negotiations and discourage hostile
takeover attempts. It is also the view of the Board of Directors that these
provisions should not discourage persons from proposing a merger or other
transaction at a price reflective of the true value of Americorp and which is
in the best interest of all stockholders.

         Attempts to acquire control of financial institutions have recently
become increasingly common. Takeover attempts which have not been negotiated
with and approved by the Board of Directors present to stockholders the risks
of a takeover on terms which may be less favorable than might otherwise be
available. A transaction which is negotiated and approved by the Board of
Directors, on the other hand, can be carefully planned and undertaken at an
opportune time in order to obtain maximum value of Americorp and its
stockholders, with due consideration given to matters such as the management
and business of the acquiring corporation and maximum strategic development
of Americorp's assets.


                                      87

<PAGE>

         An unsolicited takeover proposal can seriously disrupt the business
and management of a corporation and cause it to incur great expense. Although
a tender offer or other takeover attempt may be made at a price substantially
above the current market prices, such offers are sometimes made for less than
all of the outstanding shares of a target company. As a result, stockholders
may be presented with the alternative of partially liquidating their
investment at a time that may be disadvantageous, or retaining their
investment in an enterprise which is under different management and whose
objectives may not be similar to those of the remaining stockholders.

         Despite the belief of Americorp as to the benefits to stockholders
of these provisions, these provisions may also have the effect of
discouraging a future takeover attempt which would not be approved by
Americorp's Board, but pursuant to which stockholders may receive a
substantial premium for their shares over then current market prices. As a
result, stockholders who might desire to participate in such a transaction
may not have any opportunity to do so. The Board of Directors of Americorp,
however, has concluded that the potential benefits outweigh the possible
disadvantages.

         Pursuant to applicable law, at any annual or special meeting of its
stockholders, Americorp may adopt additional charter provisions regarding the
acquisition of its equity securities that would be permitted for a California
business corporation. Americorp does not presently intend to propose the
adoption of further restrictions on the acquisition of Americorp's equity
securities.

         The cumulative effect of the restriction on acquisition of Americorp
contained in Americorp Articles and Bylaws, federal law and California law
may be to discourage potential takeover attempts and perpetuate incumbent
management, even though certain stockholders of Americorp may deem a
potential acquisition to be in their best interest, or deem existing
management not to be acting in their best interests.


                            BUSINESS OF AMERICORP

         GENERAL

         Americorp is a California corporation organized to act as the bank
holding company for ACB. In 1987, Americorp acquired all of the outstanding
common stock of the ACB in a holding company formation transaction. Other
than holding the shares of the ACB, Americorp conducts no significant
activities, although it is authorized, with the prior approval of the Federal
Reserve Board, Americorp's principal regulator, to engage in a variety of
activities which are deemed closely related to the business of banking. At
June 30, 1998, Americorp had approximately $140 million in consolidated
assets, $83 million in consolidated net loans, $125 million in consolidated
deposits, and $11.9 million in consolidated stockholders' equity.

         ACB was licensed by the DFI and commenced operation in September
1973 as a California state bank. As a California state bank, ACB is subject
to primary supervision, examination and regulation by the DFI and the FDIC.
ACB is also subject to certain other federal laws and regulations. The
deposits


                                      88
<PAGE>

of ACB are insured by the FDIC up to the applicable limits thereof. ACB is
not a member of the Federal Reserve System.

         BANKING SERVICES

         ACB is engaged in substantially all of the business operations
customarily conducted by independent California state bank. ACB maintains
three full service-banking offices in the city of Ventura and a full service
office in the city of Camarillo. ACB's banking services include the
acceptance of checking and savings deposits, and the making of commercial,
SBA, real estate, personal, automobile and other installment loans. ACB also
offers traveler's checks, notary public and other customary bank services to
its customers. While ACB does offer credit cards to its customers, other
financial institutions issue the cards. Trust services are not offered by ACB.

         ACB's deposits are attracted primarily from individuals and small
and medium-sized business-related sources. ACB also attracts deposits from
several local agencies. In connection with municipal deposits, ACB is
generally required to pledge securities to secure such deposits, except for
the first $100,000 of such deposits which are insured by the FDIC.

         As of June 30, 1998, ACB had approximately 11,800 deposit accounts,
representing approximately 4,800 non-interest bearing (demand) accounts with
balances totaling approximately $37,642,000 for an average balance per
account of approximately $7,800; 5,400 savings, interest-bearing demand and
money market accounts with balances totaling approximately $52,375,000 for
an average balance per account of approximately $9,700 and 1,600 time
certificate of deposit accounts with balances totaling approximately
$35,516,000 for an average balance per account of approximately $21,700.

   
         Americorp is engaged in lending activities to businesses and 
consumers throughout the geographic area of Ventura County, CA.  ACB has 
concentrations in commercial loans, real estate loans and installment loans.  
The risks associated with these types of loans vary with the borrower, 
associated type of industry and prevailing economic conditions.
    

   
         Business loans are extended to a variety of commercial borrowers.  
These loans include revolving lines of credit, both secured and unsecured; 
equipment financing and term loans on real estate.  In general, business 
loans have a higher degree of risk associated with changing economic cycles, 
product obsolescence and management experience.  ACB utilizes a loan policy 
manual which sets standards for the accepted level of risk in the particular 
area under consideration.  Business loans are reviewed by experienced loan 
personnel utilizing a secondary review and approval process which ultimately 
is overseen by the Board of Directors. ACB typically obtains the guarantees 
of the borrowing company's principal owners.  Business lending risk is also
mitigated by the contracted services of an independent loan review company. 
Commercial loans outstanding, as of June 30, 1998, totaled $30,287,761, 
representing 39.16% of the portfolio.
    

   
         ACB also structures commercial loans secured by the real estate.  
These loans also vary in risk depending primarily on business cycles.  
Commercial real estate loans generally are amortized over a 20 year period 
with maturity dates of 5 years.  ACB accepts properties whose appraised 
values provides  a loan-to-value ratio of 75% or less.  Commercial loans 
outstanding, at June 30, 1998, totaled $25,540,589, representing 24.92% of the 
portfolio.  ACB is not involved with any residential tract housing 
construction and limits construction loans to either pre-sold or contract 
homes with permanent financing arranged.  Construction loans total less than 
3% of the total loan portfolio.
    

   
         ACB is also engaged in the brokering of single family first trust 
deeds to other lenders.  There is no credit risk associated with this 
activity as ACB does not directly fund any loans.
    

   
         ACB also extends loans to consumers which include automobiles, 
installment, recreational vehicles, equity lines of credit, bankcard and 
overdraft protection.  As of June 30, 1998, ACB had $6,706,952 in installment 
loans outstanding, representing 6.00% of the portfolio.  Home equity loans, 
primarily secured by second deeds of trusts, totaled $9,145,132, representing 
14.05% of the portfolio.  Bankcard loans outstanding totaled $176,972 and 
overdraft protection totaled $891,360, representing .71% and 4.02% 
respectively of the total portfolio.  ACB is currently negotiating the sale 
of the bankcard portfolio.  Management does not anticipate any loss 
associated with this sale and under current conditions, expects a premium for 
the balance outstanding.  Consumer loans are underwritten according to 
standards set in ACB's loan policy manual.  ACB utilizes Experian and Trans 
Union credit reporting agencies to obtain current information on a consumer's 
payment history, monitors delinquency trends regularly and sets reserves to 
mitigate risk in this area. 
    

         The principal sources of ACB's revenues are (i) interest and fees
on loans, (ii) interest on investments, (iii) service charges on deposit
accounts and other charges and fees, and (iv) interest on federal funds sold
(funds loaned on short-term basis to other banks). For the period ended June
30, 1998, these sources comprised 73.8%, 11.7%, 11.4% and 3.1%, respectively,
of ACB's total operating income. Virtually all of the consolidated net income
of Americorp is generated by ACB.

         ACB has not engaged in any material research activities relating to
the development of new services or the improvement of existing ACB services.

         There has been no significant change in the types of services offered
by ACB since its inception,

                                      89
<PAGE>

except in connection with new types of accounts allowed by statute or
regulation in recent years. ACB has no present plans regarding "a new line of
business" requiring the investment of a material amount of total assets.

         Most of ACB's business originates from Ventura County and there is
no emphasis on foreign sources and application of funds. ACB's business,
based upon performance to date, does not appear to be seasonal. Except as
described above, a material portion of ACB's loans is not concentrated within
a single industry or group of related industries, nor is ACB dependent upon a
single customer or group of related customers for a material portion of its
deposits. Management of ACB is unaware of any material effect upon ACB's
capital expenditures, earnings or competitive position as a result of
federal, state or local environmental regulation.

         ACB holds no patents, licenses (other than licenses obtained from
ACB regulatory authorities), franchises or concessions.

         EMPLOYEES

         As of June 30, 1998, ACB had a total of 66 full-time employees and
12 part-time employees. The management of ACB believes that its employee
relations are satisfactory.

         COMPETITION

         Banking and financial services business in California generally, and
in ACB's market areas specifically, is highly competitive. The increasingly
competitive environment is a result primarily of changes in regulation,
changes in technology and product delivery systems, and the accelerating pace
of consolidation among financial services providers. ACB competes for loans
and deposits and customers for financial services with other commercial
banks, savings and loan associations, securities and brokerage companies,
mortgage companies, insurance companies, finance companies, money market
funds, credit unions, and other nonbank financial service providers. Many of
these competitors are much larger in total assets and capitalization, have
greater access to capital markets and offer a broader array of financial
services than ACB. In order to compete with the other financial services
providers, ACB principally relies upon local promotional activities, personal
relationships established by officers, directors and employees with its
customers, and specialized services tailored to meet its customers' needs.
ACB maintains four full service-banking offices in Ventura County.

         EFFECT OF GOVERNMENTAL POLICIES AND RECENT LEGISLATION

         Banking is a business that depends on rate differentials. In
general, the difference between the interest rate paid by ACB on its deposits
and its other borrowings and the interest rate received by ACB on loans
extended to its customers and securities held in ACB's portfolio comprise the
major portion of ACB's earnings. These rates are highly sensitive to many
factors that are beyond the control of ACB. Accordingly, the earnings and
growth of ACB are subject to the influence of domestic and foreign


                                      90
<PAGE>

economic conditions, including inflation, recession and unemployment.

         The commercial banking business is not only affected by general
economic conditions but is also influenced by the monetary and fiscal
policies of the federal government and the policies of regulatory agencies,
particularly the Federal Reserve Board. The Federal Reserve Board implements
national monetary policies (with objectives such as curbing inflation and
combating recession) by its open-market operations in United States
Government securities, by adjusting the required level of reserves for
financial institutions subject to its reserve requirements and by varying the
discount rates applicable to borrowings by depository institutions. The
actions of the Federal Reserve Board in these areas influence the growth of
ACB loans, investments and deposits and also affect interest rates charged on
loans and paid on deposits. The nature and impact of any future changes in
monetary policies cannot be predicted.

         From time to time, legislation is enacted which has the effect of
increasing the cost of doing business, limiting or expanding permissible
activities or affecting the competitive balance between banks and other
financial institutions. Proposals to change the laws and regulations
governing the operations and taxation of banks, bank holding companies and
other financial institutions are frequently made in Congress, in the
California legislature and before various bank regulatory and other
professional agencies. For example, legislation has been introduced in
Congress that would repeal the current statutory restrictions on affiliations
between commercial banks and securities firms. See "SUPERVISION AND
REGULATION - Financial Modernization Legislation."

         PROPERTIES

         All ACB's offices are leased. See Note 13 to the Americorp Financial
Statements for certain additional information concerning the amount of ACB's
lease commitments.

         LEGAL PROCEEDINGS

         ACB is, from time to time, subject to various pending and threatened
legal actions which arise out of the normal course of its business. ACB is
not a party to any pending legal or administrative proceedings (other than
ordinary routine litigation incidental to ACB's business) and no such
proceedings are known to be contemplated.

         There are no material proceedings adverse to ACB to which any
director, officer, affiliate of ACB or 5 % shareholder of ACB, or any
associate of any such director, officer, affiliate or 5% shareholder of ACB
is a party, and none of the above persons has a material interest adverse to
ACB.

Changes in the dollar amount of interest earned or paid will vary from one
year to the next because of changes in the average balance ("volume") of the
various earning assets and interest-bearing liability accounts and changes in
the interest rates ("rate") applicable to each category. Table 2, "Volume and
Rate Variance Analysis of Net Interest Margin," analyzes the difference in
interest earned and paid on the major categories of assets and liabilities in
terms of the effects of volume and rate changes for the periods indicated.

     Table 6, "Non-Accrual and Non-Performing Loans", summarizes ACB's
non-performing loans for the period ended June 30, 1998 and for the last five
years. Non-performing loans consist of loans that have been placed on
non-accrual status and loans that are delinquent 90 days or more. Non-accrual
loans are loans where there is reasonable doubt as to the collectibility of
principal or interest on a loan. All non-accrual loans carry a classified loan
grade of either "substandard", "doubtful", or "loss". ACB stops recognizing
income from the interest on the loan and reverses any uncollected interest that
had been accrued but not received. These loans may or may not be adequately
collateralized, and collection efforts are being pursued.

     Proper loan grading and the early detection of potentially problematic
credits help management and the Board of Directors accurately assess ACB's
level of portfolio risk, focus resources, and provide for adequate provision
for loan loss. All loans and leases are graded using the pre-classified and
classified loan grades of "special mention", "substandard", "doubtful", or
"loss" and include non-performing loans. Each classified credit is monitored
on an on-going basis by Credit Administration. The Board's Loan Committee
receives reports on the status of these loans on a monthly basis.

     All loans and leases are defaulted on the computer system to be placed
on non-accrual status when interest and/or principal payments are past due 90
days or more. Loans and leases are reviewed periodically to determine if it
should be placed on non-accrual status even though, in some cases, the loans
are current at the time. If placed on non-accrual, removal from non-accrual
is directed by the Board.

     As of December 31, 1996, classified loans totaled $1,642,000 or 2.53% of
the outstanding loan portfolio. At December 31, 1997, the representation was
$5,217,955 or 6.2% of the outstanding portfolio. As of June 30, 1998,
classified loan totals equaled $4,055,364 or 4.8% of the outstanding
portfolio.

     Foreign Loans: ACB does not have and does not plan to have foreign loans
in its portfolio.

     Participations: From time to time ACB will sell or purchase a portion of
a loan to another bank. ACB will usually sell a portion of a loan as a method
of accommodating a large borrowing customer that would otherwise exceed ACB's
maximum credit limit for loans of this nature to any single borrower or
borrowing entity. On occasion ACB will purchase a portion of a loan, under
specifically designated terms, from other banks after these loans have been
presented and approved within the guidelines of ACB's general lending
policies.

         MANAGEMENT'S DISCUSSION AND ANALYSIS

         INTRODUCTION AND BUSINESS OF AMERICORP. Americorp is a California 
bank holding company incorporated in 1988 that is headquartered in the city 
of Ventura. The holding company currently has one subsidiary, ACB. ACB was 
chartered as a California state chartered bank, and has been operating since 
September 1973. ACB offers a wide range of banking services to households, 
professionals, and small to medium size businesses. ACB operates four banking 
offices in Ventura County: three in Ventura and one in Camarillo.

         During 1997 and 1998 ACB continued its growth strategy, reflecting 
the improvement in the Ventura County economy. During 1997, management 
continued its effort to prepare ACB for continued growth by improving data 
processing systems, automating tasks, and opening a new full service branch 
in Camarillo in September.

         1998 has been a year of change and challenge. In March, ACB's 
President/CEO resigned. ACB's Senior Credit Officer was then promoted to 
President/CEO. The Bank then hired a new Chief Operating Officer. ACB has a 
50% limited partner interest in two separate limited partnerships (Ventura 
Affordable Homes, Ltd. ("VAH") and Santa Paula Affordable Homes, Ltd.). 
Affordable Communities, Inc. ("ACI"), an unrelated entity, is the general 
partner. Both partnerships were formed for the purpose of constructing 
low-to-moderate income housing. Due to various factors, the Santa Paula 
development will not commence. The Ventura development was to construct 151 
homes, all of which have been completed. In January of 1997, a dispute arose 
between ACB as limited partner and ACI, the general partner, over the amount 
of management fees claimed to be owed to the general partner by VAH. In 
February 1997, ACB initiated a lawsuit against the general partner because of 
the dispute. On May 1, 1998, ACB and ACI negotiated a complete settlement of 
the dispute. In connection with the settlement agreement, both partnerships 
are being dissolved and ACB has received a cash distribution in full 
satisfaction of its 50% interest in the VAH partnership. As a result of the 
settlement, ACB will record no gains or losses for either partnership during 
1998.

         ECONOMIC CONDITIONS. The most comprehensive review of local economic 
conditions known to

<PAGE>

Management comes from the UCSB Economic Forecast Project which provides both 
annual forecast information and periodic updates of economic conditions in 
ACB's trade area. During 1997, the Ventura County economy continued down an 
expansion path that was steady and orderly. With the exception of the booming 
housing market, economic growth was generally modest but firm.

         Existing businesses have strengthened and are expanding. Absorption 
of office and industrial space accelerated in 1997. Home sales soared 18% 
during the year, and selling prices generally firmed. The unemployment rate 
averaged 6.5% during 1997, the lowest rate since 1990. Taxable retail sales 
increased 4.6% during 1997. A strengthening California economy, the 
continuous expansion of the U.S. economy, the unprecedented returns from the 
financial and equity markets, and the steady and efficient growth of the farm 
sector are the principal reasons for the current prosperity of the Ventura 
County economy.

         STATEMENT OF INCOME ANALYSIS

         INCOME SUMMARY. Net income was $1,103,000 in 1997 compared to 
$203,000 in 1996 and $945,000 in 1995. Basic income per share was $1.91 in 
1997, $0.35 in 1996 and $1.67 in 1995, and diluted income per share was $1.66 
in 1997, $0.31 in 1996 and $1.41 in 1995. Income for all three years was from 
normal operations. However, income from 1996 decreased significantly due to a 
large loan charge-off totaling $700,000, a write-down of bank owned mutual 
funds totaling $148,000 and a onetime write-down of property owned in 
connection with the Santa Paula Affordable Homes, Ltd. partnership totaling 
$200,000. Income for 1997 increased due to growth in real estate lending 
totaling $20,900,000.

         ACB reported net earnings of $561,000 or $0.95 basic income per 
share for the first six months of 1998. This represents a 9.8% increase over 
the same period during 1997 when net earnings were $511,000 or $0.89 basic 
income per share.

         Return on average assets for 1997 was 0.87%  compared with 0.17% for 
1996 and 0.84% for 1995.  The return on average equity was 10.22% for 1997 
compared with 1.89% for 1996 and 9.42% for 1995.

         Annualized return on average assets for the six months ended 1998 
was 0.84% compared with 0.82% for the same period during 1997. Annualized 
return on average equity for the six months ended 1998 were 9.78% compared 
with 9.68% for the same period during 1997.

         Quarterly cash dividends of $0.20 per share were paid in January, 
April of 1995. This amount was increased to $0.21 per share and paid in July 
and October 1995. Quarterly cash dividends of $0.21 per share were paid in 
January, April, July and October in 1997 and 1996. Quarterly cash dividends 
of $0.21 per share were paid in January and April of 1998.

         NET INTEREST INCOME. Net interest income is the amount by which the 
interest and amortization of fees generated from loans and other earning 
assets exceeds the cost of funding those assets, usually deposit account 
interest expense. Net interest income depends on the difference (the 
"interest rate spread")


                                       105

<PAGE>

between gross interest and fees earned on the loans and investment portfolios 
and the interest rates paid on deposits and borrowings. Net interest income 
was $7,002,000 in 1997 compared to $6,052,000 in 1996 and $6,019,000 in 1995. 
Net interest income was $3,811,000 for the six months ended June 30, 1998, 
compared to $3,363,000 for the six months ended June 30, 1997.

         Interest income grew $957,000 or 10.9% in 1997 compared with an 
increase of $253,000 or 3.0% in 1996 and an increase of $1,002,000 or 13.3% 
in 1995. The increased interest income between 1997 and 1996 is comprised of 
two key elements, interest on loans and investments. Average outstanding 
loans for 1997 and 1996 were $74,507,000 and $61,277,000, respectively. This 
represents a $13,230,000 average increase. The yield on loans for this period 
decreased from 10.25% to 10.06% or (0.17%). The increase in average 
outstanding balance and decrease in yield resulted in an overall increase in 
loan interest income totaling $1,230,000. Average outstanding investments for 
1997 and 1996 were $34,345,000 and $40,620,000, respectively. This represents 
a $(6,275,000) average decrease. The yield on investments for this period 
remained consistent at 5.66%. The decrease in average outstanding balance and 
consistent yield resulted in an overall decrease in investment interest 
income totaling $(355,000). Total fees on loans increased during 1997 by 
$82,000.

         Interest income grew $537,000 or 11.4% for six months ended June 30, 
1998 compared to the six months ended June 30, 1997. The increased interest 
income between these two periods is comprised of two key elements, interest 
on loans and investments. Average outstanding loans for interim 1998 and 1997 
were $82,684,000 and $70,627,000, respectively. This represents a $12,057,000 
average increase. The yield on loans for this period increased from 9.96% to 
10.03% or 0.07%. The increase in average outstanding balances and increase in 
yield resulted in an overall increase in loan interest income totaling 
$627,000. Average outstanding investments for interim 1998 and 1997 were 
$31,238,000 and $35,303,000, respectively. This represents a $(4,065,000) 
average decrease. The yield on investments for this period decreased from 
5.87% to 5.60% or (0.27%). The decrease in average outstanding balance and 
decrease in yield resulted in an overall decrease in investment interest 
income totaling $(162,000). Total fees on loans increased during interim 1998 
by $72,000.

         Interest expense on deposits increased $7,000 or 0.3% in 1997 
compared to $220,000 or 8.7% in 1996 and $504,000 or 25.0% in 1995.

         Interest expense increased $89,000 or 6.7% for six months ended June 
30, 1998 compared to the six months ended June 30, 1997. Average outstanding 
interest bearing deposits for interim 1998 and 1997 were $85,659,000 and 
$82,549,000, respectively. This represents a $3,111,000 average increase. The 
cost on these deposits for this period increased from 3.24% to 3.33% or 
0.09%. The increase in average outstanding balances and increase in cost 
resulted in an overall increase to interest expense for this period.

         On March 26, 1997 the prime rate changed from 8.25% to 8.50% and 
remained steady through June 30, 1998. In 1996 the prime rate decreased to 
8.25% from 8.5% on February 1, and remained steady throughout the year. The 
prime rate ranged from 9.00% to 8.50% and averaged 8.8% in 1995.


                                       106

<PAGE>

         The average loan-to-deposit ratio increased to 65.2% in 1997 
compared to 56.7% in 1996 and 59.48% in 1995. At year end the 1997 
loan-to-deposit ratio was 70.6%.

         For the six months ended June 30, 1998 and 1997 the average 
loan-to-deposit ratio increased to 69.0% compared to 63.3%. As of June 30, 
1998, the loan-to-deposit ratio was 67.6%.

         PROVISION FOR LOAN LOSSES. During 1997, net loans charged off were 
$174,000 compared with $866,000 in 1996 and $583,000 in 1995. Net loans 
charged off for the six months ended June 30, 1998 was $181,000 compared to 
$134,000 for the same period during 1997. Due to growth in the loan portfolio 
and an increase in classified assets, the provision for loan losses charged 
against income in 1997 was $410,000 compared to $346,000 (excluding the one 
time charge off of $700,000 which brought the total provision for the year to 
$1,046,000) in 1996. The provision for 1995 was $554,000. The provision for 
the six months ended June 30, 1998 was $265,000 compared to $260,000 for the 
six months ended June 30, 1997 Again, due to the growth in the loan 
portfolio, management increased the allowance for loan losses to $1,048,000 
as of December 31, 1997 compared to $812,000 as of December 31, 1996 and 
$632,000 as of December 31, 1995. As of June 30, 1998 the allowance was 
$1,131,000 compared to $938,000 for the same period during 1997. The 
provision for loan losses charged against income is added to the allowance 
for loan losses. As of December 31, 1997, the allowance was 1.24% of total 
loans compared to 1.23% at year end 1996. As of June 30, 1998, the allowance 
was 1.34% of total loans compared to 1.23% as of June 30, 1997.

         NON INTEREST INCOME. Non Interest Income represents deposit account 
services charges and other types of non-loan related fee income. Non-interest 
income was $1,571,000 in 1997 compared to $1,248,000 in 1996 and $1,384,000 
in 1995. This represents an increase of $323,000 or 25.9% between 1997 and 
1996. During 1996 ACB had a write-down on mutual funds of $148,000. During 
1997 the following significant changes were noted: equity in net income in 
partnerships decreased by $(164,000); the Bank opened a Real Estate 
department whose brokering fees represented $57,000 in income; customer 
service charges increased due to growth in overall deposit balances and 
improved efforts to collect related fees totaling $106,000; and net 
investment security sales gains totaled $54,000.

         Non-interest income for the six months ended June 30, 1998 totaled 
$672,000 compared to $607,000 for the same period during 1997. This 
represents an increase of $65,000. The major contributing factor to this 
difference is an overall increase of $58,000 in Real Estate brokering fees.

         NON INTEREST EXPENSE. Non Interest Expenses represent salaries, 
occupancy expenses, professional expenses, outside services and other 
miscellaneous expenses necessary to conduct business. Non-interest expense 
was $6,664,000 in 1997 compared to $6,014,000 in 1996 and $5,678,000 in 1995. 
This represents an increase of $650,000 or 10.8% between 1997 and 1996. 
During 1996 ACB had a onetime write-down on real estate totaling $200,000. 
During 1997 the following significant changes were noted: ACB opened a new 
branch in Camarillo, CA., occupancy expense for the year increased by 
$103,000 due to increases in rent, utilities and amortization for leasehold 
improvements; salary and related expense increased by $438,000 due to the 
paying of a


                                      107

<PAGE>

bonus during 1997 and an increased number of employees; legal expense 
increased by $144,000 due to the lawsuit with ACI; furniture and equipment 
expense rose due to the full implementation of a new bankwide computer 
network totaling $87,000

         Non-interest expense for the six months ended June 30, 1998 totaled 
$3,450,000 compared to $2,988,000 for the same period during 1997. This 
represents an increase of $462,000. The major contributing factors to this 
difference are an overall increase in salaries of $218,000 due to the changes 
that have taken place in upper management and the opening of a new branch. 
Occupancy expenses are up $87,000 due to the opening of the new branch and a 
significant increase in the Common Area Maintenance charges for one branch 
and COL increases for another. Other smaller items make up the balance of the 
remaining differences.

         PROVISION FOR INCOME TAXES. The effective income tax rate was 26% in 
1997, 15% in 1996 and 19% in 1995. For the interim period June 30, 1998 and 
1997, the effective tax rate was 27% and 29%, respectively. The accrual 
method of accounting is used to compute income taxes for financial accounting 
purposes and for income tax return preparation. For further information about 
the provision for income taxes during the June 30, 1998 and 1997 interim 
periods, please refer to the footnotes to the financial statements included 
elsewhere in this report.

         BALANCE SHEET ANALYSIS

         The improvement in the Southern California economy in 1997 and 1998 
and specifically, the improving economy in Ventura County and the community 
banks sales opportunities created by large banks' continued industry 
consolidation are reflected in the growth of ACB's balance sheets in 1997 and 
interim 1998. In 1997 ACB attracted quality customers from the larger banks 
because of the higher level of personalized service offered. As of December 
31, 1997, total assets increased by 5.6% to $134,212,000 compared to 
$127,080,000 at year end 1996. Gross loans grew to $84,702,000 as of December 
31, 1997 or 28.5% compared to $65,939,000 at December 31, 1996.

         As of June 30, 1998, total assets increased by 10.4% to $139,824,000 
compared to $126,643,000 at June 30, 1997. Gross loans grew to $84,485,000 as 
of June 30, 1998, or 13.7% compared to $74,280,000 at June 30, 1997.

         Securities and fed funds sold decreased to $31,013,000 as of 
December 31, 1997 or 29% compared to $43,659,000 as of December 31, 1996. 
Deposits grew to $119,968,000 or 5.0% as of December 31, 1997 compared to 
$114,284,000 as of December 31, 1996.

         Deposits grew to $124,975,000 or 9.9% as of June 30, 1998 compared 
to $113,682,000 as of June 30, 1997.

         INVESTMENTS. The securities portfolio of ACB serves several 
purposes: 1) it provides liquidity to even out cash flows from the loan and 
deposit activities of customers; 2) the deposits of public agencies


                                      108

<PAGE>

must be secured by certain assets of ACB as required by law, and portions of
any of the portfolio may be used for this function; 3) it is a large base of
assets, the maturity and interest rate characteristics of which can be
changed more readily than the loan portfolio to better match changes in the
deposit base and other funding sources of ACB; 4) it is an alternative
interest-earning use of funds when loan demand is light; and, 5) it may
provide partially tax-exempt income.

         ACB's investment portfolio primarily consists of Federal Agency
Securities, Mortgage-backed Securities, Municipal Securities, Mutual Funds
and overnight investments in the Federal Funds market. During 1997 the
investment portfolio decreased by $12,647,000. The yield curve during 1997
shifted downward. This resulted in several Agency and Municipal securities
being called placing a significant amount of principal dollars back into
ACB's hands. Due to high loan demand, these funds and fed funds dollars were
reinvested into loans. See loans section for a further explanation of loan
growth.

         During 1998 this trend has continued. However, ACB has increased its
fed funds balance as of June 30, 1998 by $5,800,000 to $8,200,000 compared
with $2,400,000 as of June 30, 1997. This increase is due to ACB's management
of liquidity risk.

         LOANS. Loans outstanding, net of loan loss allowance increased to
$83,397,000 as of December 31, 1997, representing growth of 28.4% over the
December 31, 1996 balance of $64,943,000. A strong local economy contributed
to an increase in loan demand, primarily in the real estate sector.

         Real Estate loans increased from $11,026,000 at December 31, 1996 to
$31,920,000 at December 31, 1997. This represents an increase of $20,894,000
or 189.5%. Although a significant portion of this increase was attributed to
a reclassification of existing loans due to a data conversion in May 1997,
another contributing factor to the loan growth was the opening of a Loan
Production office in the City of Camarillo in October 1996. Total loans
outstanding at this location grew to $7,545,000 as of December 31, 1997.

         For the interim period ending June 30, 1998, outstanding loans
totaled $83,074,000 compared to $73,114,000 as of June 30, 1997. This
represents an increase of $9,960,000 or 13.6%. Real estate loans are up
$13,568,000 during this period for reasons previously discussed. Commercial
loans have increased $3,579,000 due to reclassifying existing loans and the
strong local economy. Consumer loans are down $(2,918,000) or (27.8%) due to
loan payoffs and reclassifications due to the data conversion. Equity lines
are down $(2,680,000) or (22.6%) due primarily to the refinancing of first
mortgages and home sales which have increased significantly in Ventura County
during the past twelve months.

         ALLOWANCE FOR LOAN LOSSES. Lending is a risk based business that
recognizes losses despite prudent efforts to minimize risk.

         The business of extending loans entails the possibility of risk
despite prudent efforts to minimize exposure. Economic downturns, unexpected
changes in a borrowers cash flow, and competitive pressures are among a
myriad of conditions that affect the timely repayment of loans.

         The allowance for loan losses is a valuation reserve against the
banks total loan portfolio representing an amount thought to be adequate to
cover future loan losses. Included in this amount are all loans that have
been identified by management, outside auditors and regulatory agencies as
requiring additional monitoring and collective attention. Also included are
loans that management considers to be potential collection problems.

         As of December 31, 1997, the allowance for loan losses was
$1,048,000 compared to $812,000 at year end 1996 and $632,000 at year end
1995. As a percentage of outstanding loans, the allowance was 1.24% as of
December 31, 1997, and 1.23% in 1996 and 1.05% in 1995. For the six months
ended June 30, 1998, the allowance for loan losses was $1,131,000 compared to
$938,000 as of June 30, 1997. As a percentage of outstanding loans, the
allowance was 1.34% as of June 30, 1998 and 1.27% for the same period during
1997.

         Actual charges to the provision for losses charged to expense are as
follows:

</TABLE>

         In management's opinion, the allowance for loan losses as of June
30, 1998, is adequate based upon its ongoing analysis of the loan portfolio.
Management also utilizes an independent loan review company to conduct a
quarterly analysis of the allowance. The most recent external examination
conducted as of March 31, 1998, supported the adequacy of the current level
of the reserve.

         OTHER ASSETS. Bank premises and equipment, other real estate owned,
investment in partnerships and other assets are the four components of other
assets. Other assets as of December 31, 1997, totaled $8,340,000, compared to
$7,936,000 as of December 31, 1996, and $8,985,000 as of December 31, 1995.
Other assets as of June 30, 1998, totaled $5,815,000 compared to $8,240,000
as of June 30, 1997. The decrease between these two interim periods is
$2,425,000. As previously discussed, ACB is a limited partner in VAH. During
May 1998, ACB was paid back its full investment in the partnership totaling
$2,550,000.

         DEPOSITS. In order to meet the demand for loans and to accommodate
the day-to-day activities of it's depositors, the bank maintains an adequate
liquidity position through the use of overnight investments in federal funds
and other short term investments.

         CAPITAL. Total shareholders equity at December 31, 1997 totaled
$11,351,000, which represented


                                      110

<PAGE>

an 8.4% increase from $10,472,000 at December 31, 1996. At June 30, 1998,
shareholder equity was $11,901,000 compared to $10,718,000 for the same
period during 1997.

         For all periods reviewed, the Company maintains capital ratios above
the Federal regulatory guidelines for a "well capitalized" bank. The ratios
are as follows:

         YEAR 2000. ACB is working to resolve the potential impact of the
year 2000 on the ability of ACB's computerized information systems to
accurately process information that may be date-sensitive. Any of ACB's
programs that recognize a date using "00" as the year 1900 rather than the
year 2000 could result in errors or system failures. ACB utilizes a number of
computer programs across its entire operation. ACB has not completed its
assessment, but currently believes that costs of addressing this issue will
not have a material adverse impact on ACB's financial position. However, if
ACB and third parties upon which its relies are unable to address this issue
in a timely manner, it could result in a material financial risk to ACB. In
order to assure this does not occur, ACB plans to devote all resources
required to resolve any significant year 2000 issues in a timely manner. See
"RISK FACTORS - Year 2000 Risks and Preparedness."

         LIQUIDITY. Liquidity is ACB's ability to meet fluctuations in
deposit levels and to provide for the credit needs of its customers. The
objective in liquidity management is to maintain a balance between the
sources and uses of funds. Principal sources of liquidity include interest
and principal payments on loans and investments, proceeds from the maturity
of investments and growth in deposits. ACB holds overnight Federal funds as a
cushion from temporary liquidity needs. During the first six months of 1998,
Federal funds averaged $6,971,000 or 5.22% of total average assets. During
the first six month of 1997, Federal funds averaged $3,428,000 or 2.77% of
total average assets. In addition, ACB maintains Federal funds credit lines
with major correspondents totaling $4,700,000, subject to the customary terms
for such arrangements. ACB also maintains repurchase agreements totaling
$10,000,000.

         NET INTEREST MARGIN. As previously discussed, net interest income is
the difference between the interest income and fees earned on loans and
investments and the interest expense paid on deposits and


                                     111

<PAGE>

other liabilities. The amount by which interest income exceeds interest
expense depends on two factors: the volume of earnings assets compared to the
volume of interest-bearing deposits and liabilities, and the interest rate
earned on those interest earning assets compared with the interest rate paid
on those interest-bearing deposits and liabilities.

         Net interest margin is the net interest income expressed as a
percentage of earning assets. To maintain its net interest margin, the ACB
must manage the relationship between interest earned and paid, and that
relationship is subject to the following types of risks that are related to
changes in interest rates.

         MARKET RISK. The market values of assets or liabilities on which the
interest rate is fixed will increase or decrease with changes in market
interest rates. If the Bank invests funds in a fixed rate long-term security
and then interest rates rise, the security is worth less than a comparable
security just issued because the older security pays less interest than the
newly issued security. If the older security had to be sold, ACB would have
to recognize a loss. Correspondingly, if interest rates decline after a fixed
rate security is purchased, its value increases. Therefore, while the value
changes regardless of which direction interest rates move, the adverse
exposure to "market risk" is primarily due to rising interest rates. This
exposure is lessened by managing the amount of fixed rate assets and by
keeping maturities relatively short. However, this strategy must be balanced
against the need for adequate interest income because variable rate and
shorter fixed rate securities generally earn less interest than longer term
fixed rate securities.

         There is market risk relating to ACB's fixed rate or term
liabilities as well as its assets. For liabilities, the adverse exposure to
market risk is to lower rates because ACB must continue to pay the higher
rate until the end of the term. However, because the amount of fixed rate
liabilities is significantly less than the fixed rate assets, and because the
average maturity is substantially less than for the assets, the market risk
is not as great.

         Net interest margin was 6.49% in 1997 compared to 5.99% in 1996 and
6.31% in 1995. Net interest margin was 6.76% for the six months ended June
30, 1998, compared to 6.36% for the six months ended June 30, 1997.

         The following is a summary of the carrying amounts and estimated
fair values of selected Bank financial assets and liabilities at December 31,
1997:

</TABLE>

         Other than a relatively small difference due to credit quality
issues pertaining to loans, the difference between the carrying amount and
the fair value is a measure of how much more or less valuable ACB's financial
instruments are to it than when acquired. The net difference for
interest-bearing financial assets is $24,000. The amount is not deemed to be
significant compared to the outstanding balances taken as a whole.

         The net difference for interest-bearing financial liabilities is
$46,000. The amount is not deemed to be significant compared to the
outstanding balances taken as a whole.

         MISMATCH RISK. Another interest-related risk arises from the fact
that when interest rates change, the changes do not occur equally in the
rates of interest earned and paid because of difference in the contractual
terms of the assets and liabilities held. ACB has a large portion of its loan
portfolio tied to the prime interest rate. If the prime rate is lowered
because of general market conditions, e.g., other banks are lowering their
lending rates; these loans will be repriced. If ACB were at the same time to
have a large proportion of its deposits in long-term fixed rate certificates,
net interest income would decrease immediately. Interest earned on loans
would decline while interest expense would remain at higher levels for a
period of time because of the higher rate still being paid on the deposits.

         A decrease in net interest income could also occur with rising
interest rates if ACB had a large portfolio of fixed rate loans and
securities funded by deposit accounts on which the rate is steadily rising.
This exposure to "mismatch risk" is managed by matching the maturities and
repricing opportunities of assets and liabilities. This is done by varying
the terms and conditions of the products that are offered to depositors and
borrowers. For example, if many depositors want longer-term certificates
while most borrowers are requesting loans with floating interest rates, ACB
will adjust the interest rates on the certificates and loans to try to match
up demand. ACB can then partially fill in mismatches by purchasing securities
with the appropriate maturity or repricing characteristics.

         One of the means of monitoring this matching process is the use of a
"gap" report table. This table shows the extent to which the maturities or
repricing opportunities of the major categories of assets and liabilities are
matched based upon specific interest rate change scenarios and assumptions.
ACB utilizes gap reports assuming simultaneous interest rate shifts of up to
+/- 200 basis points.

         The following table shows the estimated impact to net interest
income for an instantaneous shift in various interest rates as of June 30,
1998 (the dollar change in net interest income represents the estimated
change for the next 12 months):

                             -200 basis points        $(412,000)
</TABLE>

         ACB has adequate capital to absorb any potential losses as a result
of a decrease in interest rates. Periods of more than one year are not
estimated because steps can be taken to mitigate the adverse effects of any
interest rate changes.

         BASIS RISK. A third interest-related risk arises from the fact that
interest rates rarely change in a parallel or equal manner. The interest
rates associated with the various assets and liabilities differ in how often
they change, the extent to which they change, and whether they change sooner
or later than other interest rates. For example, while the repricing of a
specific asset and a specific liability may fall in the same period of a gap
report the interest rate on the asset my rise 100 basis points, while market
conditions dictate that the liability increases only 50 basis points. While
evenly matched in the gap report, ACB would experience an increase in net
interest income. This exposure to "basis risk" is the type of interest risk
least able to be managed, but is also the least dramatic. Avoiding
concentration in only a few types of assets or liabilities is the best
insurance that the average interest received and paid will move in tandem,
because the wider diversification means that many different rates, each with
their own volatility characteristics, will come into play. ACB has made an
effort to minimize concentrations in certain types of assets and liabilities.

     COMPENSATION

     None of the persons named in the preceding table relating to
executive officers received compensation from Americorp and/or ACB of
$100,000 or more in 1997.

     In 1997, each director received $1,000 per month in director's fees
except as indicated in the following sentences. The Secretary to the Board
(Mr. Cryne) received $2,000 per month in fees and the Vice-Chairman of the
Board,(Mr. Lagomarsino) also received $2,000 per month in fees. Mr. Jue (the
Chairman of the Board) received $3,500 per month in fees.

     During 1998, ACB's Directors' Retirement Plan was terminated and the
benefits payable thereunder frozen. Benefits will only be payable upon
retirement and then either on a lump sum basis or pursuant to a 10 year
pay-out. Directors Cryne, Jue, Lagomarsino and Wood were the only
participants in the plan. It is currently anticipated that the amount of such
additional accrual will be approximately $175,600.

     EMPLOYMENT AGREEMENT

     In connection with his appointment as President and Chief Executive
Officer of Americorp and ACB, ACB entered into an employment agreement with
Gerald J. Lukiewski as of March 2, 1998. The agreement, as amended and
extended, currently provides for a three year term with an annual salary of
$135,000. The agreement also provides for participation in ACB's bonus plan
and certain other benefits, including vacation, automobile allowance,
insurance, retirement benefits and expense reimbursements. In the event of
termination without cause, the agreement provides for the lesser of (i) three
months of additional salary and benefits or (ii) the remaining salary and
benefits due under the term of the agreement.

      CERTAIN TRANSACTIONS

      Some of the current directors and officers of Americorp and ACB and
the companies with which they are associated have been customers of , and
have had banking transactions with ACB, in the ordinary course of ACB's
business, and ACB expects to continue to have such banking transactions in
the future. All loans and commitments to lend included in such transactions
have been made on substantially the same terms, including interest rates and
collateral, as those prevailing at the time for comparable transactions with
persons of similar creditworthiness, and in the opinion of management of ACB,
have not involved more than the normal risk of repayment or presented any
other unfavorable features.

      STOCK OWNERSHIP

      Except as set forth in the following table, management of Americorp
does not know of any person who owns beneficially more than 5% of Americorp
Stock. The following table sets forth certain

                              BUSINESS OF CIB

     GENERAL

     CIB commenced operations as a national banking association on
September 16, 1985. Effective February 20, 1998, CIB converted to a
state-chartered member bank. CIB is regulated by the DFI and the Federal
Reserve Bank ("FRB"). CIB's deposits are insured up to the maximum legal
limits by the FDIC. CIB is also subject to certain other federal laws and
regulations. As of June 30, 1998, CIB had total assets of approximately $86.9
million, total deposits of $79.3 million, and total stockholders' equity of
$7.4 million.

     CIB is a community bank conducting a general commercial banking
business that serves individuals, professionals and small to medium-sized
businesses. CIB offers a full range of commercial banking services, including
commercial loans, various types of consumer and real estate loans, the
acceptance of check and savings deposits, money market and Super NOW
accounts, and other non-deposit banking services. CIB's main office and
administrative headquarters office are both located at 300 Esplanade Drive,
Oxnard, California 93030 and its telephone number is (805) 487-6581. CIB
maintains two additional branch offices, located at 155 South A Street,
Oxnard, California, and 2510 East Las Posas Road, Suite M, Camarillo,
California.

     CIB has not engaged in any material research activities relating to
the development of new services or the improvement of existing CIB services.


                                     118


<PAGE>

or the improvement of existing CIB services.

     There as been no significant change in the types of services offered
by CIB since its inception, except in connection with new types of accounts
allowed by statute or regulation in recent years. CIB has no present plans
regarding "a new line of business" requiring the investment of a material
amount of total assets.

     Most of CIB's business originates from Ventura County and there is
no emphasis on foreign sources and application of funds. CIB's business,
based upon performance to date, does not appear to be seasonal. Except as
described above, a material portion of CIB's loans is not concentrated within
a single industry or group of related industries, nor is CIB dependent upon a
single customer or group of related customers for a material portion of its
deposits. Management of CIB is unaware of any material effect upon CIB's
capital expenditures, earnings or competitive position as a result of
federal, state or local environmental regulation.

     CIB holds no patents, licenses (other than licenses obtained from
CIB regulatory authorities), franchises or concessions.

     EMPLOYEES

     As of June 30, 1998, CIB had a total of 55 full-time employees and
12 part-time employees. The management of CIB believes that its employee's
relations are satisfactory.

     COMPETITION

     Banking and financial services business in California generally, and
in CIB's market areas specifically, is highly competitive. The increasingly
competitive environment is a result primarily of changes in regulation,
changes in technology and product delivery systems, and the accelerating pace
of consolidation among financial services providers. CIB competes for loans
and deposits and customers for financial services with other commercial
banks, savings and loan associations, securities and brokerage companies,
mortgage companies, insurance companies, finance companies, money market
funds, credit unions, and other nonbank financial service providers. Many of
these competitors are much larger in total assets and capitalization, have
greater access to capital markets and offer a broader array of financial
services than CIB. In order to compete with the other financial services
providers, CIB principally relies upon local promotional activities, personal
relationships established by officers, directors and employees with its
customers, and specialized services tailored to meet its customers' needs.
CIB maintains three full service-banking offices in Ventura County.

     EFFECT OF GOVERNMENTAL POLICIES AND RECENT LEGISLATION

     Banking is a business that depends on rate differentials. In
general, the difference between the interest rate paid by CIB on its deposits
and its other borrowings and the interest rate received by CIB on


                                     119

<PAGE>

loans extended to its customer and securities held in CIB's portfolio
comprise the major portion of CIB's earnings. These rates are highly
sensitive to many factors that are beyond the control of CIB. Accordingly,
the earnings and growth of CIB are subject to the influence of domestic and
foreign economic conditions, including inflation, recession and unemployment.

     The commercial banking business is not only affected by general
economic conditions but is also influenced by the monetary and fiscal
policies of the federal government and the policies of regulatory agencies,
particularly the Federal Reserve Board. The Federal Reserve Board implements
national monetary policies (with objectives such as curbing inflation and
combating recession) by its open-market operations in United States
Government securities, by adjusting the required level of reserves for
financial institutions subject to its reserve requirements and by varying the
discount rates applicable to borrowings by depository institutions. The
actions of the Federal Reserve Board in these areas influence the growth of
CIB loans, investment and deposits and also affect interest rates charged on
loans and paid on deposits. The nature and impact of any future changes in
monetary policies cannot be predicted.

     From time to time, legislation is enacted which has the effect of
increasing the cost of doing business, limiting or expanding permissible
activities or affecting the competitive balance between banks and other
financial institutions. Proposals to change the laws and regulations
governing the operations and taxation of banks, bank holding companies and
other financial institutions are frequently made in Congress, in the
California legislature and before various bank regulatory and other
professional agencies For example, legislation has been introduced in
Congress that would repeal the current statutory restrictions on affiliations
between commercial banks and securities firms.

     PROPERTIES

     All CIB's offices are leased. See Note 5 to the CIB Financial
Statements for certain additional information concerning the amount of CIB's
lease commitments.

     LEGAL PROCEEDING

     CIB is, from time to time, subject to various pending and threatened
legal actions which arise out of the normal course of its business. CIB is
not a party to any pending legal or administrative proceedings (other than
ordinary routine litigation incidental to CIB's business) and no such
proceedings are known to be contemplated.

     MANAGEMENT'S DISCUSSION AND ANALYSIS

     BUSINESS ORGANIZATION

     Channel Islands Bank (CIB) is a California chartered bank
headquartered in Oxnard, California. As of June 30, 1998 CIB operated three
full-service branches in Ventura County, California. Other than investing
excess funds, CIB currently conducts no other significant business activities.

     CIB offers a full range of traditional commercial banking products
and services to individuals,


                                     120

<PAGE>

merchants, small and medium-sized businesses and professionals in Ventura
County, its primary service area. The commercial banking services that CIB
offers includes the acceptance of checking and savings deposits, and the
making of various types of installment, commercial and real estate loans. In
addition, CIB provides safe deposit, collection, travelers' checks, and other
customary non-deposit banking services. The Bank emphasizes personalized
service and convenience of banking and attracts banking customers by offering
morning through early evening banking hours. CIB has 24-hour Automated Teller
Machines ("ATM's") at all three of its banking offices.

     The following sections set forth a discussion of the significant
operating changes, business trends, financial condition, earnings, capital
position and liquidity that have occurred in the two-year period ended
December 31, 1997, and the six month periods ending June 30, together with an
assessment, when considered appropriate, of external factors that may affect
CIB in the future. This discussion should be read in conjunction with CIB's
consolidated financial statements and notes attached hereto as Appendix B.

     OVERVIEW

     CIB earned net income of $800,000 for the year ended December 31,
1997, representing an increase of $474,000, or 168% over 1996 income of
$326,000. On a diluted per common share basis, net income for 1997 was $1.60
compared to $.66 per share for the preceding year. The improvement in net
income in 1997 was primarily due to growth in net interest income and
noninterest income that outpaced increases in operating expenses. Net income
in 1997 benefited from the sale of mortgage servicing rights which resulted
in a gain of $492,000 reflected in the Statements of Income as other income.
These and other factors are discussed in more detail later in this analysis.

     Net income for the six month period ending June 30, 1998 was
$338,000, a decrease of $4,000, or 1% over income of $342,000 for the six
month period ending June 30, 1997. This decrease was primarily due to an
increase in salaries and benefits related to increases in staff, and to costs
related to the application for the state banking charter.

     Common shareholder's equity increased by $960,000 or 17.2% during
1997 from $5,596,000 at December 31, 1996 to $6,556,000 at December 31, 1997,
through the retention of earnings and the exercise of stock options. It is
the objective of management to maintain adequate capital for future growth
through retention of earnings. In both 1997 and 1996 CIB paid two semiannual
cash dividends of $0.10.

     Common Shareholders' Equity was $7,440,000 on June 30, 1998, a
$884,000, or 13.5%, increase over the December 31,1997 balance of $6,556,000
through the retention of earnings and the exercise of stock options. CIB paid
a $0.10 cash dividend during the six month period ending June 30, 1998.

     The following table sets forth several key operating ratios for 1997
and 1996, and for the six month periods ending June 30 1998 and 1997 (dollars
in thousands).

         EARNINGS ANALYSIS

         NET INTEREST INCOME. Net interest income refers to the difference 
between the interest paid on deposits and borrowings, and the interest earned 
on loans and investments. It is the primary component of the earnings of a 
financial institution. The primary factors that impact net interest income 
are the composition and volume of interest-earning assets and 
interest-bearing liabilities, the amount of noninterest-bearing liabilities 
and nonaccrual loans, and changes in market interest rates.

         Net interest income for 1997 was $4.9 million or 6.8% of 
interest-earning assets compared to $4.5 million and 6.3% of interest-earning 
assets in 1996. The increase in 1997 compared to 1996 is primarily 
attributable to increases in the amounts of interest-earning assets.

         Net interest income for the six month period ending June 30, 1998 is 
$2.6 million, an increase of $200,000 from the $2.4 million for the six month 
period ending June 30, 1997. The increase is primarily


                                     123

<PAGE>

attributable to increases in the amount of interest-earning assets.

         Interest income for 1997 was $6.8 million compared to $6.3 million 
for 1996. The increase in 1997 is primarily due to overall growth in 
interest-earning assets.

         Interest income for the period ending June 30, 1998 was $3.6 million 
compared to $3.3 million for the period ending June 30, 1997, a $300,000 
increase. This increase is primarily attributable to overall growth in 
interest-bearing assets.

         Interest expense has remained fairly stable in both amount and rate 
over the past two years. Total interest expense was $1.9 million in both 1997 
and 1996. The overall rate paid on interest-bearing liabilities was 3.59% in 
1997 and 3.68% in 1996.

         Interest expense increased $100,000 from $0.9 million to $1.0 
million for the six month periods ended June 30, 1997 and June 30, 1998, 
respectively. This increase was primarily due to overall growth in 
interest-bearing deposits.

         The following table sets forth changes in interest income and 
interest expense for each major category of interest-earning asset and 
interest-bearing liability, and the amount of change attributable to volume 
and rate changes for the years indicated. Changes not solely attributable to 
rate or volume have been allocated to volume and rate changes in proportion 
to the relationship of the absolute dollar amounts of the changes in each 
(dollar amounts in thousands):

         NONINTEREST INCOME. Noninterest income increased $400,000 in 1997 
from $.7 million in 1996 to $1.1 million in 1997. During 1997 CIB sold the 
servicing rights on mortgage loans totaling approximately $54 million. CIB 
received $492,000 from the sale which represents approximately 90% of the 
proceeds from the sale. CIB will receive the balance of the proceeds in 1998.

         Noninterest income increased $98,000 from $354,000 for the six month 
period ending June 30, 1997 to $453,000 for the same six month period in 
1998. This increase resulted primarily from increases in deposit account 
service charges and a gain on the sale of a property classified as other real 
estate owned.

         NONINTEREST EXPENSE. Noninterest expense reflects the costs of 
products and services related to systems, facilities and personnel for CIB.

         Noninterest expense for 1997 was $4.3 million, a net increase of 
$400,000 or 10.9% from the $3.9 million reported in 1996. One significant 
component of this increase was salaries and employee benefits which increased 
$193,000, primarily from increased staffing levels. Costs related to the 
corporate office move and to the application for a state banking charter also 
increased costs in 1997.

         Noninterest expense for the six month period ending June 30, 1998 
was $2.4 million, a $300,000 increase from $2.1 million for the first six 
months of 1997. Increase in salaries and benefits, related to staff 
increases, accounted for $148,000 of this increase. An increase in occupancy 
costs related to the move of the corporate office, and legal costs related to 
the application for the state banking charter account for most of the balance 
of the difference.

         INCOME  TAXES.  CIB's income tax  provisions were $576,000 and 
$235,000 for 1997 and 1996, respectively.  The effective tax rate was 41.9% 
in 1997 and 42.0% in 1996.

         Income taxes were $236,000 for the six month period ending June 30, 
1998, and $248,000 for the six month period ending June 30, 1997.

         BALANCE SHEET ANALYSIS

         Total assets of CIB at December 31, 1997 were $89.0 million compared 
to $74.6 million on December 31,1996, representing an increase of 19.3%. 
Based on average balances, total assets of $80.3 million in 1997 represent a 
4.3% increase over $77.0 for 1996.

         CIB's total assets at June 30, 1998 was $86.9 million, and increase 
of $6.2 million, representing and increase of 7.7% over the June 30, 1997 
balance of $80.7 million.

</TABLE>

         Average loans in 1997 were $50.8 million representing an increase of 
7.9% over 1996. Average loans represented 63.28% of average assets in 1997 
compared to 61.19% 1996. Average loans were $55.6 million representing 64.09% 
of average assets for the six month period ending June 30, 1998.

         Commercial and industrial loans consist of credit lines for 
operating needs, loans for equipment purchases and working capital, and 
various other business purposes. At December 31, 1997, CIB had commercial 
loans outstanding representing 24.1% of total loans compared to 27.1% at 
December 31, 1996. Commercial loans represented 25.3% of total loans at June 
30, 1998.

         Real estate construction loans expressed as a percentage of total 
loans were 3.0% and 5.1% at December 31, 1997 and 1996, respectively. 
Construction loans were 4.6% of total loans on June 30, 1998. The 
construction loans outstanding are generally composed of commitments to 
customers within CIB's service area for construction of custom, semi-custom 
single family residences, and industrial buildings.

          Real estate mortgage loans, which consist primarily of loans to 
CIB's depositors secured by trust deeds on commercial and residential real 
estate, expressed as a percentage of total loans were 49.5% and 43.6% at 
December 31, 1997 and 1996, respectively. At $28.9 million, other real estate 
loans represent 48.6% of total loans on June 30, 1998.

         Installment loans to individuals and all other loans include a range 
of traditional consumer loan products offered by CIB such as home equity and 
personal lines of credit and loans to finance purchases of autos, boats, 
recreational vehicles, and various other consumer items. Dealer loans, which 
are automobile loans purchased from local automobile dealers, are included in 
this category. Unearned discounts on dealer loans are recognized as income 
over the term of the loans by the sum-of-the-month-digits method (Rule of 
78's.) At December 31, 1997, consumer loans outstanding were $12.4 million 
representing 23.5% of total loans. This compares to consumer loans of $12.6 
million representing 24.2% of total loans at December 31, 1996. Consumer 
loans outstanding were $12.8 million representing 21.5% of total loans on 
June 30, 1998.

         RISK ELEMENTS

         CIB assesses and manages credit risk on an ongoing basis through 
lending policies. Management strives to continue the historically low level 
of credit losses by continuing its emphasis on credit quality in the loan 
approval process, active credit administration and regular monitoring.

         In extending credit and commitments to borrowers, CIB generally 
requires collateral and/or guarantees as security. The repayment of such 
loans is expected to come from cash flow or from proceeds


                                       128

<PAGE>

from the sale of selected assets of the borrower. CIB's requirement for 
collateral and/or guarantees is determined on a case-by-case basis in 
connection with management's evaluation of the credit worthiness of the 
borrower. Collateral held varies but may include accounts receivable, 
inventory, plant and equipment, income-producing properties, residences and 
other real property. CIB secures its collateral by perfecting its interest in 
business assets, obtaining deeds of trust, or outright possession among other 
means.

   
     CIB provides the community with three general categories of loans:  (i) 
commercial, (ii) consumer and (iii) real estate.  Within each of these 
categories, CIB makes available various types of loans.  For example, CIB 
makes commercial loans for working capital lines of credit, term loans, 
equipment loans, consumer loans for automobile purchases, secured and 
unsecured personal loans, overdraft protection, and real estate loans for 
single family residence purchases, commercial/industrial building purchases, 
home equity lines of credit and construction loans.  In each instance, CIB 
has established specific underwriting guidelines and policies.  While it is 
recognized that there is inherent risk in the granting of credit, it is 
through the establishment and adherence to specific underwriting guidelines 
and policies for each type of loan that CIB endeavors to mitigate this risk.  
Additionally, CIB has established specific loan limits for lending personnel. 
Loans in excess of these limits require further approval of a Directors' 
Loan Committee and may involve the approval of the entire Board of Directors.
    

   
     CIB has established a loan review/classification system to detect and 
follow credits that have a greater than a normal degree of risk.  Further, 
CIB has developed a methodology to provide for an adequate Allowance for Loan 
and Lease Losses ("ALLL").  This methodology involves the analysis of various 
pools of loans utilizing the loan loss history for those pools, a system of 
loan migration analysis and a provision for Year 2000 risk.  Additionally, 
CIB adjusts the ALLL based on an analysis of the trend in past due and 
non-accrual loans; the trend in the volume and severity of problem credits; 
the volume and nature of the existing loan portfolio; concentration of 
credits in the loan portfolio; changes in lending policies and systems; and 
changes in the experience, ability, and depth of lending personnel; off 
balance sheet credit risk; international credit risk and trends in the 
national, state and local economy.
    

   
     Further, CIB has segmented its real estate loan portfolio and 
established specific concentration limits as a percentage of capital 
permitted in each category.  An aggregate limit of real estate loans as a 
percentage of total assets has also been established.  The vast majority of 
single family residence loans originated by CIB are underwritten to specific 
investor guidelines and resold into the secondary market, further mitigating 
the concentration and credit risk within this category.
    

         Management believes that its lending policies and underwriting 
standards will tend to minimize losses in an economic downturn, however, 
there is no assurance that losses will not occur under such circumstances.

         NONPERFORMING ASSETS

         Management generally places loans on nonaccrual status when they 
become 90 days past due, unless the loan is well secured and in the process 
of collection. Loans are charged-off when, in management's opinion, 
collection appears unlikely. The following table provides information with 
respect to the components of CIB's nonperforming assets at the dates 
indicated:

         Interest due but excluded from interest income in nonaccrual loans 
was approximately $0 in 1998 and 1997, and $39,000 in 1996. No payments 
received on nonaccrual loans were included in interest income in 1998, 1997 
and 1996.

         The average recorded investment in loans that are considered 
impaired under SFAS No. 114 was $293,000 in 1997, and $812,000 for 1996, and 
$0 for the six months ended June 30, 1998, which are included as nonaccrual 
loans above. Such impaired loans had a valuation allowance of $0 on December 
31, 1997 and June 30, 1998, and $42,721 for December 31, 1996. CIB recognized 
no interest on impaired loans in 1997 or 1996.

         Other real estate owned is acquired through foreclosure or other means.
These properties are recorded on an individual basis at the estimated fair
values less selling expenses. At December 31, 1997, other real estate owned was
comprised of one commercial building with a carrying value of $152,000. This
property was subsequently sold resulting in a $0 balance in other real estate
owned on June 30, 1998.

PROVISION AND ALLOWANCE FOR LOAN LOSS

         The allowance for loan losses is maintained at a level that is
considered adequate to provide for the loan losses inherent in CIB's loans. The
provision for loan losses was $370,000 in 1997, $696,000 in 1996, and $58,000
for the six month period ending June 30, 1998.

         The following table summarizes, for the years indicated, changes in the
allowances for loan losses arising from loans charged-off, recoveries on loans
previously charged-off, and additions to the allowance which have been charged
to operating expenses and certain ratios relating to the allowance for loan
losses:

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

loan losses by loan type for the years indicated and the percent of loans in

had a deposit mix of 37.8% in time and savings deposits, 32.2% in money market
and NOW deposits, and 30.0% in noninterest-bearing demand deposits. CIB net
interest income is enhanced by its percentage of noninterest-bearing deposits.

     At June 30, 1998, CIB had a deposit mix of 40.8% in time and savings
deposits,  28.2% in money market and NOW deposits, and 31.0% in
noninterest-bearing demand deposits

         LIQUIDITY AND INTEREST RATE SENSITIVITY

         LIQUIDITY. Liquidity management refers to CIB's ability to provide
funds on an ongoing basis to meet fluctuations in deposit levels as well as the
credit needs and requirements of its clients. Both assets and liabilities
contribute to CIB's liquidity position. Federal funds lines, short-term
investments and securities, and loan repayments contribute to liquidity, along
with deposit increases, while loan funding and deposit withdrawals decrease
liquidity. CIB assesses the likelihood of projected funding requirements by
reviewing historical funding patterns, current and forecasted economic
conditions and individual client funding needs. Commitments to fund loans and
outstanding letters of credit at June 30, 1998, December 31, 1997, and December
31, 1996 totaled approximately $17.2, $12.6 million, and $8.3 million,
respectively. Such loans relate primarily to revolving lines of credit,
construction loans and other commercial loans.

         CIB's sources of liquidity consist of its deposits with other banks,
overnight funds sold to correspondent banks and unpledged short-term, marketable
investments. On December 31, 1997, liquid assets totaled $32.4 million or 36.4%
of total assets as compared to $27.2 million or 36.5% of total assets on
December 31, 1996. On June 30, 1998 liquid assets totaled $27.2 million or 31.3%
of total assets. In addition to liquid assets, CIB maintains lines of credit
with correspondent banks available on a short-term basis. Informal agreements
are also in place with various other banks to purchase participations in loans,
if necessary.

         INTEREST RATE SENSITIVITY. Interest rate sensitivity is a measure of
the exposure to fluctuations in CIB's future earnings caused by fluctuation in
interest rates. Such fluctuations result from the mismatch in repricing
characteristics of assets and liabilities at a specific point in time. This
mismatch, or interest rate sensitivity gap, represents the potential mismatch in
the change in the rate of accrual of interest revenue and interest expense from
a change in market interest rates. Mismatches in interest rate repricing among
assets and liabilities arise primarily from the interaction of various customer
businesses (i.e. types of loans versus the types of deposits maintained) and
from management's discretionary investment and funds gathering activities. CIB
attempts to manage its exposure to interest rate sensitivity, but due to its
size and direct competition from the major banks, it must offer products which
are competitive in the market place, even if less than optimum with respect to
its interest rate exposure.

         The table below sets forth the interest rate sensitivity of CIB's
interest-earning assets and interest-bearing liabilities as of June 30, 1998,
using the interest rate sensitivity gap ratio. For purposes of the

         CAPITAL RESOURCES

         CIB's total shareholders'  equity was $7.4 million on June 30, 1998,
$6.6 million at December 31, 1997 and $5.6 million as of December 31, 1996.

         CIB is subject to regulations issued by the Department of Financial
Institutions and the FDIC which require maintenance of a certain level of
capital. These regulations impose two capital standards: a risk-based capital
standard and a leverage capital standard.

         Under the risk-based capital guidelines, assets reported on an
institution's balance sheet and certain off-balance sheet items are assigned to
risk categories, each of which has an assigned risk weight. Capital ratios are
calculated by dividing the institution's qualifying capital by its period-end
risk-weighted assets. The guidelines establish two categories of qualifying
capital: Tier 1 Capital (defined to include common shareholders' equity and
noncumulative perpetual preferred stock) and Tier 2 Capital defined to include
limited life (and in the case of bank, cumulative) preferred stock, mandatory
convertible securities, subordinated debt, and a limited amount of reserves for
loan and lease losses. Each institution is required to maintain a risk-based
capital ratio (including Tier 1 and Tier 2 capital) of 8%, of which at least
half


                                       134
<PAGE>

must be Tier 1 capital.

         Under the leverage capital standard an institution is required to
maintain a minimum ratio of Tier 1 capital to the sum of its quarterly average
total assets and quarterly average reserve for loan losses, less intangibles not
included in Tier 1 capital. Period-end assets may be used in place of quarterly
average total assets on a case-by-case basis. A minimum leverage ratio of 3% is
required for institutions which have been determined to be in the highest of
five categories used by regulators to rate financial institutions and which are
not experiencing or anticipating significant growth. All other organizations are
required to maintain leverage ratios of at least 100 to 200 basis points above
the 3% minimum. The table below represents the capital and leverage ratios of
CIB as of December 31, 1997:

</TABLE>

         The Federal Deposit Insurance Corporation Improvement Act of 1991
("FDICIA") substantially revises banking regulation and establishes a framework
for determination of capital adequacy of financial institutions. Under the
FDICIA, financial institutions are placed into one of five capital adequacy
categories as follows: (1) "well capitalized" consisting of institutions with a
total risk-based capital ratio of 10% or greater, a Tier 1 risk-based ratio of
6% or greater and a leverage ratio of 5% or greater, and the institution is not
subject to an order, written agreement, capital directive or prompt corrective
action directive; (2) "adequately capitalized" consisting of institutions with a
total risk-based capital ratio of 8% or greater, a Tier 1 risk-based capital
ratio of 4% or greater and a leverage ratio of 4% or greater, and the
institution does not meet the definition of a "well-capitalized" institution;
(3) "under capitalized" consisting of institutions with a total risk-based
ration of less than 4%; (4) "significantly undercapitalized" consisting of
institutions with a total risk-based capital ratio of less than 6%, Tier 1
risk-based capital ratio


                                       135
<PAGE>

of less than 3%, or a leverage ratio of less than 3%;
and (5) "critically undercapitalized" consisting of an institution with a ratio
of tangible equity to total assets that is equal to or less than 2%.

         Financial institutions classified as under capitalized or below are
subject to various limitations including, among other matters, certain
supervisory actions by bank regulatory authorities and restrictions relating to
(i) growth of assets, (ii) payment of interest on subordinated indebtedness,
(iii) payment of dividends or other capital distributions, and (vi) payment of
management fees to a parent holding company. The FDICIA requires regulatory
authorities to initiate corrective action regarding financial institutions,
which fail to meet minimum capital requirements. Such actions may, among other
matters, require that the financial institution augment capital and reduce total
assets. Critically undercapitalized financial institutions may also be subject
to appointment of a receiver or conservator unless the financial institution
submits an adequate capitalization plan.

         EFFECTS OF INFLATION

         The financial statements and related financial information presented
herein have been prepared in accordance with GAAP, which require the measurement
of financial position and operating results in terms of historical dollars
without considering changes in the relative purchasing power of money over time
due to inflation. Unlike most industrial companies, virtually all of the assets
and liabilities of a financial institution are monetary in nature. As a result,
interest rates have a more significant impact on a financial institution's
performance than effects of general levels of inflation. Interest rates do not
necessarily move in the same direction or same magnitude as the price of goods
and services.

         YEAR 2000 ISSUES

   
     CIB has established a working committee of senior management, a director
and other employees to plan and monitor CIB's compliance with Year 2000 ("Y2K")
issues. This committee has developed a policy setting forth priorities and a
timetable for CIB to follow in this process. The Federal Reserve Bank in their
most recent exam has indicated that CIB was in compliance with the progress
standards established by the Federal Reserve Bank with Y2K issues.

     CIB has budgeted expenditures related to its Y2K readiness program.  The
budget is made up of two major components.  The first component consists of
items that will be expensed directly to net income including the salaries and
benefits of dedicated Y2K personnel, public relations, customer and employee
awareness programs, training, professional assistance through consultants and
third party reviews.  This is budgeted at $115,000.  As of June 30, 1998,
$15,000 or 13% of this component has been spent.
     
     The second component consists of items that will be accounted for as fixed
assets and include the replacement of non compliant equipment and the cost of
hardware and software upgrades.  This component is budgeted at $49,000. As of
June 30, 1998 $24,000 or 49% of this component has been spent. Management
reviews the budget from time to time as the Y2K program is implemented.  There
is no assurance that additional amounts will not be added to the amounts already
allocated for Y2K program.

     CIB has obtained the services of three professional organizations that
provide legal review of contracts and insurance, audit review of the
effectiveness of the Y2K program and technological assistance in reviewing or
conducting ClB's testing programming.

     CIB has developed a contingency plan that identifies the mission critical
processes and service providers.  An alternative process has been identified for
each mission critical item.  In addition, on the assumption that the original or
alternative process fails at the point of processing in the Year 2000, a
contingency plan has been designed that will provide minimum levels of service
or outputs until the failed system can be repaired or replaced.  Most of these
contingency plans are manual effort systems or manual systems enhanced by micro-
computers.  Test results indicates that the original or alternative system for
each mission critical system should meet the demands of processing in the Year
2000.  As a reasonable worst case the manual systems designed should provide the
minimum levels of service for the time required to repair or replace failed
systems. However, in case of failure the ultimate impact on financial operations
is not known nor is it known what impact a regional or nationwide failure of
power or communications would have on the financial performance of CIB.

     An important contingent alternative to CIB's technology oriented mission
critical systems is the use of ACB's systems.  ACB and CIB intend to have the
CIB systems converted to the ACB systems shortly after consummation of the
Merger.  However, there is no assurance that conversion to ACB's systems will
proceed according to plan.  If the conversion to ACB's system is not successful,
substantial additional expense may be incurred in converting CIB's systems, and
customer service could be disrupted, causing a possible loss of business.

     In April 1998 the Bank began mailing Y2K questionnaires to its existing
borrowers with total liability to CIB of a predetermined threshold amount.
These questionnaires were designed to provide CIB with information by which it
could evaluate the borrower's awareness of and sensitivity to Y2K risk.
Additionally, the Bank requires this same  questionnaire and evaluation of new
borrowers meeting the threshold amount.  Depending upon the rating on the
evaluation, CIB will contact the borrower on a quarterly basis until it can be
determined that the Y2K risk is low.  CIB is presently requiring applicable loan
agreements to contain language addressing the borrower's Y2K readiness.  On all
loan participations purchased, CIB is requiring assurances from the lead lender
that it has obtained a Y2K questionnaire from the borrower and also that the
lead lender is satisfactorily progressing toward Y2K compliance. CIB has
established a Y2K risk component to its analysis of the its Allowance for Loan
and Lease Losses.
    


         IMPACT OF NEW ACCOUNTING PRONOUNCEMENTS

         In June 1997 the Financial Accounting Standards Board issued Statement
No. 130, "REPORTING COMPREHENSIVE INCOME". This statement, which is effective
for the year ending December 31, 1998, establishes standards of disclosure and
financial statement display for reporting comprehensive income and its
components.

         In June 1997, the Financial Accounting Standards Board issued Statement
No. 131, "DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION."
This statement changes current practice under SFAS 14 by establishing a new
framework on which to base segment reporting (referred to as the


                                      136

<PAGE>

management approach) and also requires certain related disclosures about 
products and services, geographic areas and major customers. The disclosures 
are required for the year ending December 31, 1998.

         BOARD OF DIRECTORS

         At the Effective Time and pursuant to the Agreement, the Boards of 
Directors of the Americorp and ACB will consist of four (4) members of the 
current CIB Board and five (5) members from Americorp and ACB, including 
Americorp's and ACB's President. It is currently contemplated that the four 
members of the CIB Board who will continue to serve as directors of the 
Americorp and ACB following the Effective Time are Joseph Priske, Michael T. 
Hribar, Edward F. Paul and Jacqueline Pruner. For information on the members

         None of the directors or executive officers of CIB have, during the 
last five years, been involved in any legal proceedings that are material to 
an evaluation of the ability or integrity of any director or executive 
officer of CIB.

         SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

         The following tables set forth information as of the Record Date 
pertaining to beneficial ownership (as defined below) of CIB's no par value

than 5% of its Common Stock (a "Principal Shareholder"), and (ii) 
individually, each of the "Executive Officers" (as defined below) of CIB, its 
current directors and nominees for the office of director, and (iii) all 
directors and Executive Officers(1) of CIB as a group. The information 
contained herein has been obtained from CIB's records and from information 
furnished to CIB by each individual or entity required by law to report such

         DIRECTOR AND EXECUTIVE OFFICER COMPENSATION

         EXECUTIVE COMPENSATION

         Any Executive Officer serving as a Director of CIB does not receive 
additional compensation for attending Board and committee meetings, and such 
attendance is remunerated by the compensation of such person in his or her 
capacity as an Executive Officer of CIB. For the fiscal year ended December 
31, 1997, the aggregate cash compensation paid to or accrued for all 
Executive Officers of CIB, as a group (3 persons), for services rendered to 
CIB in all capacities was $283,561.76.

                                      141

<PAGE>

On June 23, 1998, Mr. Spencer executed an agreement to release CIB from any 
and all liability, and in return CIB agreed to pay Mr. Spencer all accrued 
salary and unused vacation, certain health benefits, $60,000 representing 
approximately six months salary, and $51,375 representing the value of Mr. 
Spencer's CIB stock options. The parties agreed to make three installment 
payments to Mr. Spencer, with the last installment payment due on October 1, 
1998.

         OPTION GRANTS FOR 1997 AND 1998

         There were no stock options granted pursuant to the 1985 Incentive 
Stock Option Plan to the Directors or Executive Officers in 1997. As of July 
31, 1998, 45,000 shares had been granted to Directors and Executive Officers 
in 1998 pursuant to the 1998 Stock Option Plan.

         OPTION EXERCISES IN 1997 AND 1998

         There were no exercises in 1997 of stock options by Executive 
Officers, and 18,089 shares were exercised by Directors in 1997. As of July 
31, 1998, 67,401 shares were exercised by Directors in 1998.

         STOCK OPTION PLANS

         1985 INCENTIVE STOCK OPTION PLAN

         The 1985 Incentive Stock Option Plan of CIB adopted by the Board of 
Directors on July 18, 1985, and approved by the shareholders on July 30, 1985 
(the "1985 Plan"), intended to advance the interests of CIB by encouraging 
stock ownership on the part of its officers and directors. According to its 
terms, the 1985 Plan terminated on July 31, 1994. At the 1994 Annual Meeting 
of shareholders, the shareholders approved certain amendments to the 1985 
Plan, including an extension of time within which the grantees of options 
under the 1985 Plan would be able to exercise their options for an additional 
five years or until July 31, 1999. Other basic terms of the 1985 Plan 
remained essentially unchanged.

         Since the nine (9) year term of the 1985 Plan expired on July 31, 
1994, stock options may no longer be granted under the 1985 Plan. However, 
options previously granted and not exercised as of July 31, 1994 may not have 
expired on that date. Under the terms of the 1985 Plan, options available for 
grant under the 1985 Plan which were not granted, have been added to CIB's 
authorized but unissued shares.

         1998 STOCK OPTION PLAN

         On March 19, 1998, the Board of Directors of CIB adopted, subject to 
approval by a majority of the outstanding shares, the 1998 Stock Option Plan 
(the "1998 Plan"). The 1998 Plan provides for the grant of "Incentive stock 
options," within the meaning of Section 422 of the Internal Revenue Code of 
1986, as amended, and "non-qualified options," which are options not intended 
to qualify as incentive stock options. Under the 1998 Plan, options for the 
acquisition of an aggregate of 100,000 shares of CIB's common stock may be 
granted to directors, officers and employees of CIB. Incentive stock options 
may


                                      142

<PAGE>

not be granted to non-employee directors. The 1998 Plan is administered by 
the full Board of Directors acting as the Stock Option Committee which has 
sole discretion and authority, consistent with the provisions of the 1998 
Plan, to determine which eligible participants will receive options, the time 
when options will be granted, the terms of options granted and the number of 
shares which will be subject to options granted under the applicable 1998 
Plan.

         With the adoption on March 19, 1998, of the 1998 Plan by the Board, 
the Board granted, subject to stockholder approval of the Plan, 5,000 
non-qualified options to acquire shares of Bank common stock at an exercise 
price of $18.00 per share to each of the seven non-officer directors of CIB. 
Twenty (20) percent of these options are to vest on the date of such grant 
with the remainder to vest 20 percent per year for the succeeding four years. 
In addition, on June 18, 1998, the Board granted 5,000 incentive stock 
options to each executive officer of CIB at an exercise price per share of 
$20.00.

         CHANNEL ISLANDS BANK 401(K) PLAN

         On September 1, 1994, CIB's Board adopted a 401(K) Plan ("Plan"), 
which is a defined contribution plan. The Plan is a "qualified" pension plan 
(as defined in the Employee Retirement Income Security Act of 1974) for the 
exclusive benefit of eligible employees and their beneficiaries. The Plan is 
intended to provide death, disability or retirement income to participating 
employees and their beneficiaries. Under the Plan, an employee must complete 
a minimum of ninety (90) days of consecutive service and attain the age of 
eighteen (18) years before he or she is eligible to participate in the Plan. 
Eligible employees may elect to defer not less than 1 % or more than 15% of 
their annual salary up to a dollar limit set by law each year based on cost 
of living changes. CIB makes matching contributions equal to 50% of the 
employee share on employee deferrals of up to 6%. These matching 
contributions are monthly, discretionary amounts which may vary from month to 
month. The annual expense to CIB of its contributions to the Plan for the 
years ended December 31, 1997 and 1996 were $24,940.99 and $14,779.53, 
respectively. Contributions to the Plan are held and invested by the Trustee 
of the Plan.

         INDEBTEDNESS OF MANAGEMENT

         Some of CIB's directors, Executive Officers and principal 
shareholders (including beneficial owners of 5% or more of CIB's Common 
Stock), as well as their associates, are customers of, and have had banking 
transactions with, CIB in the ordinary course of CIB's business and CIB 
expects to have such ordinary banking transactions with such persons in the 
future. In the opinion of the management of CIB, all loans and commitments to 
lend included in such transactions were made in compliance with applicable 
laws, and on substantially the same terms, including interest rates and 
collateral, as those prevailing for comparable transactions with other 
persons of similar credit worthiness, and did not involve more than a normal 
risk of collectability or present other unfavorable features. Loans to 
individual directors and officers must comply with CIB's lending policies and 
statutory lending limits, and prior Board approval, not including the vote of 
any director with a financial or other interest in such transaction, is 
required for most of these loans. At December 31, 1997, the aggregate 
indebtedness of CIB's Executive Officers, directors and principal 
shareholders along with their associates was $1,263,290.96.


                                      143

<PAGE>

         EXECUTIVE OFFICER AGREEMENTS

         On July 7, 1998, CIB entered into an employment agreement with Mr.
Thomas Anthony as CIB's Senior Vice President and Senior Lending Officer. The
term of the agreement commenced on June 18, 1998 and shall terminate on
December 31, 1999. Mr. Anthony shall receive a salary of $95,258.89 per year,
four weeks of vacation, use of a Bank owned automobile, a stock option of
5,000 shares vesting 20% per year at an exercise price of $20.00 per share,
certain health and medical benefits, and reimbursement of certain business
expenses. Mr. Anthony may be terminated with cause for any of the various
reasons enumerated in the agreement, and upon such termination, Mr. Anthony
would receive only accrued salary and payment for any unused vacation. The
agreement also provides for the payment of six months salary if Mr. Anthony
is terminated without cause. If Mr. Anthony is terminated, Mr. Anthony may
not, for a one year period following termination, solicit any customers or
employees of CIB to move their banking or employment relationships from CIB.

         Also on July 7, 1998, CIB entered into an employment agreement with
Mr. Allen Partridge as CIB's Senior Vice President and Chief Financial
Officer. The term of the agreement commenced on June 18, 1998 and shall
terminate on December 31, 1999. Mr. Partridge shall receive a salary of
$88,400 per year, four weeks of vacation, a stock option of 5,000 shares
vesting 20% per year at an exercise price of $20.00 per share, certain health
and medical benefits, and reimbursement of certain business expenses. Mr.
Partridge may be terminated with cause for any of the various reasons
enumerated in the agreement, and upon such termination, Mr. Partridge would
receive only accrued salary and payment for any unused vacation. The
agreement also provides for the payment of six months salary if Mr. Partridge
is terminated without cause. If Mr. Partridge is terminated, Mr. Partridge
may not, for a one year period following termination, solicit any customers
or employees of CIB to move their banking or employment relationships from
CIB.

         CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         Some of the Company's Directors and executive officers and their
immediate families, as well as the companies with which they are associated,
are customers of, or have had banking transactions with, CIB in the ordinary
course of CIB's business, and CIB expects to have banking transactions with
such persons in the future. In management's opinion, all loans and
commitments to lend included in such transactions were made in the ordinary
course of business, in compliance with applicable laws on substantially the
same terms, including interest rates and collateral, as those prevailing for
comparable transactions with other persons of similar creditworthiness and,
in the opinion of management, did not involve more than a normal risk of
repayment or presented other unfavorable features.

                       SUPERVISION AND REGULATION

         Americorp, ACB and CIB are extensively regulated under both federal
and state law, as discussed below.

                                      144

<PAGE>

         AMERICORP

         Americorp is a bank holding company within the meaning of the Bank
Holding Company Act of 1956, as amended (the "Bank Holding Company Act"), and
is registered as such with, and subject to the supervision of, the Federal
Reserve Board. Americorp is required to file with the Federal Reserve Board
quarterly and annual reports and such additional information as the Federal
Reserve Board may require pursuant to the Bank Holding Company Act. The
Federal Reserve Board may conduct examinations of bank holding companies and
their subsidiaries.

         Americorp is required to obtain the approval of the Federal Reserve
Board before it may acquire all or substantially all of the assets of any
bank, or ownership or control of the voting shares of any bank if, after
giving effect to such acquisition of shares, Americorp would own or control
more than 5% of the voting shares of such bank. Prior approval of the Federal
Reserve Board is also required for the merger or consolidation of Americorp
and another bank holding company.

         Americorp is prohibited by the Bank Holding Company Act, except in
certain statutorily prescribed instances, from acquiring direct or indirect
ownership or control of more than 5% of the outstanding voting shares of any
company that is not a bank or bank holding company and from engaging,
directly or indirectly, in activities other than those of banking, managing
or controlling banks or furnishing services to its subsidiaries. However,
Americorp may, subject to the prior approval of the Federal Reserve Board,
engage in any, or acquire shares of companies engaged in, activities that are
deemed by the Federal Reserve Board to be so closely related to banking or
managing or controlling banks as to be a proper incident thereto.

         Americorp, and any subsidiaries which it may acquire or organize,
are deemed to be "affiliates" of ACB within the meaning of that term as
defined in the Federal Reserve Act. This means, for example, that there are
limitations (a) on loans by ACB to affiliates, and (b) on investments by ACB
in affiliates' stock as collateral for loans to any borrower. Americorp and
its subsidiary are also subject to certain restrictions with respect to
engaging in the underwriting, public sale and distribution of securities.

         Americorp and ACB are prohibited from engaging in certain tie-in
arrangements in connection with an extension of credit, sale or lease of
property or furnishing of services. Section 106(b) of the Bank Holding
Company Act Amendments of 1970 generally prohibits a bank from tying a
product or service to another product or service offered by ACB, or by any of
its affiliates. Further, Americorp and ACB are required to maintain certain
levels of capital. See, "Effect of Governmental Policies and Recent
Legislation - Capital Standards."

         The Federal Reserve Board may require that Americorp terminate an
activity or terminate control of or liquidate or divest subsidiaries or
affiliates when the Federal Reserve Board determines that the activity or the
control or the subsidiary or affiliates constitutes a significant risk to the
financial safety, soundness or stability of any of its banking subsidiaries.
The Federal Reserve Board also has the authority

                                      145

<PAGE>

to regulate provisions of certain bank holding company debt, including
authority to impose interest ceilings and reserve requirements on such debt.
Under certain circumstances, Americorp must file written notice and obtain
approval from the Federal Reserve Board prior to purchasing or redeeming its
equity securities.

         Under the Federal Reserve Board's regulations, a bank holding
company is required to serve as a source of financial and managerial strength
to its subsidiary banks and may not conduct its operations in an unsafe and
unsound manner. In addition, it is the Federal Reserve Board's policy that in
serving as a source of strength to its subsidiary banks, a bank holding
company should stand ready to use available resources to provide adequate
capital funds to its subsidiary banks during periods of financial stress or
adversity and should maintain the financial flexibility and capital-raising
capacity to obtain additional resources for assisting its subsidiary banks. A
bank holding company's failure to meet its obligations to serve as a source
of strength to its subsidiary banks will generally be considered by the
Federal Reserve Board to be an unsafe and unsound banking practice or a
violation of the Federal Reserve Board's regulations or both.

         ACB

         ACB is extensively regulated under both federal and state law. Set
forth below is a summary description of certain laws which relate to the
regulation of ACB. The description does not purport to be complete and is
qualified in its entirety by reference to the applicable laws and regulations.

         ACB is chartered under the laws of the State of California and its
deposits are insured by the FDIC to the extent provided by law. ACB is
subject to the supervision of, and is regularly examined by, the DFI and the
FDIC. Such supervision and regulation include comprehensive reviews of all
major aspects of ACB's business and condition.

         Various requirements and restrictions under the laws of the United
States and the State of California affect the operations of ACB. Federal and
California statutes relate to many aspects of ACB's operations, including
reserves against deposits, interest rates payable on deposits, loans,
investments, mergers and acquisitions, borrowings, dividends and locations of
branch offices. Further, ACB is required to maintain certain levels of
capital.

          California law and regulations of the DFI authorize California
licensed banks, subject to applicable limitations and approvals of the DFI to
(1) provide real estate appraisal services, management consulting and advice
services, and electronic data processing services; (2) engage directly in
real property investment or acquire and hold voting stock of one or more
corporations, the primary activities of which are engaging in real property
investment; (3) organize, sponsor, operate or render investment advice to an
investment company or to underwrite, distribute or sell securities in
California; and (4) invest in the capital stock, obligations or other
securities of corporations not acting as insurance companies, insurance
agents or insurance brokers. In November 1988, Proposition 103 was adopted by
California voters. The DFI has established certain procedures to be followed
by banks desiring to engage in certain insurance

                                      146

activities.

         CIB

         As a California state chartered bank whose deposits are insured by
the FDIC, CIB is regulated under the same federal and state laws as ACB.

         CAPITAL STANDARDS

         The Federal Reserve Board and FDIC have adopted risk-based minimum
capital guidelines (for bank holding companies and insured non-member state
banks, respectively) intended to provide a measure of capital that reflects
the degree of risk associated with a banking organization's operations for
both transactions reported on the balance sheet as assets and transactions,
such as letters of credit and recourse arrangements, which are recorded as
off balance sheet items. Under these guidelines, nominal dollar amounts of
assets and credit equivalent amounts of off balance sheet items are
multiplied by one of several risk adjustment percentages, which range from 0%
for assets with low credit risk, such as certain U.S. Treasury securities, to
100% for assets with relatively high credit risk, such as business loans.

         A banking organization's risk-based capital ratios are obtained by
dividing its qualifying capital by its total risk adjusted assets. The
regulators measure risk-adjusted assets, which includes off balance sheet
items, against both total qualifying capital (the sum of Tier 1 capital and
limited amounts of Tier 2 capital) and Tier 1 capital. Tier 1 capital
consists primarily of common stock, retained earnings, noncumulative
perpetual preferred stock (cumulative perpetual preferred stock for bank
holding companies) and minority interests in certain subsidiaries, less most
intangible assets. Tier 2 capital may consist of a limited amount of the
allowance for possible loan and lease losses, cumulative preferred stock,
long-term preferred stock, eligible term subordinated debt and certain other
instruments with some characteristics of equity. The inclusion of elements of
Tier 2 capital is subject to certain other requirements and limitations of
the federal banking agencies. The federal banking agencies require a minimum
ratio of qualifying total capital to risk-adjusted assets of 8% and a minimum
ratio of Tier 1 capital to risk-adjusted assets of 4%.

         In addition to the risked-based guidelines, federal banking
regulators require banking organizations to maintain a minimum amount of Tier
1 capital to total assets, referred to as the leverage ratio. For a banking
organization rated in the highest of the five categories used by regulators
to rate banking organizations, the minimum leverage ratio of Tier 1 capital
to total assets is 3%. For all banking organizations not rated in the highest
category, the minimum leverage ratio must be at least 100 to 200 basis points
above the 3% minimum, or 4% to 5%. In addition to these uniform risk-based
capital guidelines and leverage ratios that apply across the industry, the
regulators have the discretion to set individual minimum capital requirements
for specific institutions at rates significantly above the minimum guidelines
and ratios.

         In June 1996, the federal banking agencies adopted a joint agency
policy statement to provide

                                      147

<PAGE>

guidance on managing interest rate risk. These agencies indicated that the
adequacy and effectiveness of a bank's interest rate risk management process
and the level of its interest rate exposures are critical factors in the
agencies' evaluation of ACB's capital adequacy. A bank with material
weaknesses in its risk management process or high levels of exposure relative
to its capital will be directed by the agencies to take corrective action.
Such actions will include recommendations or directions to raise additional
capital, strengthen management expertise, improve management information and
measurement systems, reduce levels of exposure, or some combination thereof
depending upon the individual institution's circumstances.

         The federal banking agencies issued an interagency policy statement
on the allowance for loan and lease losses which, among other things,
establishes certain benchmark ratios of loan loss reserves to classified
assets. The benchmark set forth by such policy statement is the sum of (a)
assets classified loss; (b) 50 percent of assets classified doubtful; (c) 15
percent of assets classified substandard; and (d) estimated credit losses on
other assets over the upcoming 12 months.

         Federally supervised banks and savings associations are currently
required to report deferred tax assets in accordance with SFAS No. 109. The
federal banking agencies recently issued final rules governing banks and bank
holding companies, which became effective April 1, 1995, which limit the
amount of deferred tax assets that are allowable in computing an institutions
regulatory capital. The standard has been in effect on an interim basis since
March 1993. Deferred tax assets that can be realized for taxes paid in prior
carryback years and from future reversals of existing taxable temporary
differences are generally not limited. Deferred tax assets that can only be
realized through future taxable earnings are limited for regulatory capital
purposes to the lesser of (i) the amount that can be realized within one year
of the quarter-end report date, or (ii) 10% of Tier 1 Capital. The amount of
any deferred tax in excess of this limit would be excluded from Tier 1
Capital and total assets and regulatory capital calculations.

         Future changes in regulations or practices could further reduce the
amount of capital recognized for purposes of capital adequacy. Such a change
could affect the ability of ACB to grow and could restrict the amount of
profits, if any, available for the payment of dividends.

         Under applicable regulatory guidelines, Americorp and ACB were each
considered "Well Capitalized" at June 30, 1998.

         On January 1, 1998, new legislation became effective which, among
other things, gave the power to the DFI to take possession of the business
and properties of a bank in the event that the tangible shareholders' equity
of the bank is less than the greater of (i) 3% of the bank's total assets or
(ii) $1,000,000.

         PROMPT CORRECTIVE ACTION

         Federal law requires each federal banking agency to take prompt
corrective action to resolve the problems of insured depository institutions,
including but not limited to those that fall below one or more

                                      148

<PAGE>

prescribed minimum capital ratios. The law required each federal banking
agency to promulgate regulations defining the following five categories in
which an insured depository institution will be placed, based on the level of
its capital ratios: well capitalized, adequately capitalized,
undercapitalized, significantly undercapitalized and critically
undercapitalized.

         An insured depository institution generally will be classified in
the following categories based on capital measures indicated below:

<TABLE>
<S><C>
         "Well capitalized"                                      "Adequately capitalized"
          ----------------                                        ----------------------
         Total risk-based capital of 10%;              Total risk-based capital of 8%;
         Tier 1 risk-based capital of 6%; and          Tier 1 risk-based capital of 4%; and
         Leverage ratio of 5%.                         Leverage ratio of 4%.

         "Undercapitalized"                            "Significantly undercapitalized"
          ----------------                              ------------------------------
         Total risk-based capital less than 8%;        Total risk-based capital less than 6%;
         Tier 1 risk-based capital less than 4%; or    Tier 1 risk-based capital less than 3%; or
         Leverage ratio less than 4%.                  Leverage ratio less than 3%.

         "Critically undercapitalized"
          ---------------------------
         Tangible equity to total assets less than 2%.

</TABLE>

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

         The law prohibits insured depository institutions from paying
management fees to any controlling persons or, with certain limited
exceptions, making capital distributions if after such transaction the
institution would be undercapitalized. If an insured depository institution
is undercapitalized, it will be closely monitored by the appropriate federal
banking agency, subject to asset growth restrictions and required to obtain
prior regulatory approval for acquisitions, branching and engaging in new
lines of business. Any undercapitalized depository institution must submit an
acceptable capital restoration plan to the appropriate federal banking agency
45 days after becoming undercapitalized. The appropriate federal banking
agency cannot accept a capital plan unless, among other things, it determines
that the plan (i) specifies the steps the institution will take to become
adequately capitalized, (ii) is based on realistic assumptions and (iii) is
likely to succeed in restoring the depository institution's capital. In
addition, each company controlling an undercapitalized depository institution
must guarantee that the institution will comply with the capital plan until
the depository institution has been adequately capitalized on an average
basis during each of four consecutive calendar quarters and must otherwise
provide adequate assurances of performance. The aggregate liability of such
guarantee is limited to the lesser of (a) an amount equal to 5% of the
depository institution's total assets at the time the institution became
undercapitalized or (b)

                                      149

<PAGE>

the amount which is necessary to bring the institution into compliance with
all capital standards applicable to such institution as of the time the
institution fails to comply with its capital restoration plan. Finally, the
appropriate federal banking agency may impose any of the additional
restrictions or sanctions that it may impose on significantly
undercapitalized institutions if it determines that such action will further
the purpose of the prompt correction action provisions.

         An insured depository institution that is significantly
undercapitalized, or is undercapitalized and fails to submit, or in a
material respect to implement, an acceptable capital restoration plan, is
subject to additional restrictions and sanctions. These include, among other
things: (i) a forced sale of voting shares to raise capital or, if grounds
exist for appointment of a receiver or conservator, a forced acquisition;
(ii) restrictions on transactions with affiliates; (iii) further limitations
on interest rates paid on deposits; (iv) further restrictions on growth or
required shrinkage; (v) modification or termination of specified activities;
(vi) replacement of directors or senior executive officers; (vii)
prohibitions on the receipt of deposits from correspondent institutions;
(viii) restrictions on capital distributions by the holding companies of such
institutions; (ix) required divestiture of subsidiaries by the institution;
or (x) other restrictions as determined by the appropriate federal banking
agency. Although the appropriate federal banking agency has discretion to
determine which of the foregoing restrictions or sanctions it will seek to
impose, it is required to force a sale of voting shares or merger, impose
restrictions on affiliate transactions and impose restrictions on rates paid
on deposits unless it determines that such actions would not further the
purpose of the prompt corrective action provisions. In addition, without the
prior written approval of the appropriate federal banking agency, a
significantly undercapitalized institution may not pay any bonus to its
senior executive officers or provide compensation to any of them at a rate
that exceeds such officer's average rate of base compensation during the 12
calendar months preceding the month in which the institution became
undercapitalized.

         Further restrictions and sanctions are required to be imposed on
insured depository institutions that are critically undercapitalized. For
example, a critically undercapitalized institution generally would be
prohibited from engaging in any material transaction other than in the
ordinary course of business without prior regulatory approval and could not,
with certain exceptions, make any payment of principal or interest on its
subordinated debt beginning 60 days after becoming critically
undercapitalized. Most importantly, however, except under limited
circumstances, the appropriate federal banking agency, not later than 90 days
after an insured depository institution becomes critically undercapitalized,
is required to appoint a conservator or receiver for the institution. The
board of directors of an insured depository institution would not be liable
to the institution's shareholders or creditors for consenting in good faith
to the appointment of a receiver or conservator or to an acquisition or
merger as required by the regulator.

         In addition to measures taken under the prompt corrective action
provisions, commercial banking organizations may be subject to potential
enforcement actions by the federal regulators for unsafe or unsound practices
in conducting their businesses or for violations of any law, rule, regulation
or any condition imposed in writing by the agency or any written agreement
with the agency.

         SAFETY AND SOUNDNESS STANDARDS

         Effective in 1995 the federal banking agencies adopted final
guidelines establishing standards for safety and soundness, as required by
the Federal Deposit Insurance Corporation Improvement Act of 1991 (AFDICIA).
These standards are designed to identify potential safety and soundness
concerns and ensure that action is taken to address those concerns before
they pose a risk to the deposit insurance fund. The standards relate to (i)
internal controls, information systems and internal audit systems; (ii) loan
documentation; (iii) credit underwriting; (iv) asset growth; (v) earnings;
and (vi) compensation, fees and benefits. If a federal banking agency
determines that an institution fails to meet any of these standards, the
agency may require the institution to submit to the agency an acceptable plan
to achieve compliance with the standard. In the event the institution fails
to submit an acceptable plan within the time allowed by the agency or fails
in any material respect to implement an accepted plan, the agency must, by
order, require the institution to correct the deficiency. Effective October
1, 1996, the federal banking agencies promulgated safety and soundness
regulations and accompanying interagency compliance guidelines on asset
quality and earnings standards. These new guidelines provide six standards
for establishing and maintaining a system to identify problem assets and
prevent those assets from deteriorating. The institution should (i) conduct
periodic asset quality reviews to identify problem assets; (ii) estimate the
inherent losses in those assets and establish reserves that are sufficient to
absorb estimated losses; (iii) compare problem asset totals to capital; (iv)
take appropriate corrective action to resolve problems assets; (v) consider
the size and potential risks of material asset concentrations; and (vi)
provide periodic asset reports with adequate information for management and
the board of directors to assess the level of risk. These new guidelines also
set forth standards for evaluating and monitoring earnings and for ensuring
that earnings are sufficient for the maintenance of adequate capital and
reserves. If an institution fails to comply with a safety and soundness
standard, the appropriate federal banking agency may require the institution
to submit a compliance plan. Failure to submit a compliance plan or to
implement an accepted plan may result in enforcement action.

         PREMIUMS FOR DEPOSIT INSURANCE

         Federal law has established several mechanisms to increase funds to
protect deposits insured by Bank Insurance Fund ("BIF") administered by the
FDIC. The FDIC is authorized to borrow up to $30 billion from the United
States Treasury; up to 90% of the fair market value of assets of institutions
acquired by the FDIC as receiver from the Federal Financing Bank; and from
depository institutions that are members of the BIF. Any borrowings not
repaid by asset sales are to be repaid through insurance premiums assessed to
member institutions. Such premiums must be sufficient to repay any borrowed
funds within 15 years and provide insurance fund reserves of $1.25 for each
$100 of insured deposits. The FDIC also has authority to impose special
assessments against insured deposits.

         The FDIC has adopted final regulations implementing a risk-based
premium system required by federal law. Under the regulations, which cover
the assessment periods commencing on and after January 1, 1994, insured
depository institutions are required to pay insurance premiums within a range
of 23 cents per $100 of deposits to 31 cents per $100 of deposits depending
on their risk classification. The FDIC,


                                      151

<PAGE>

effective September 15, 1995, lowered assessments from their rates of $.23 to
$.31 per $100 of insured deposits to rates of $.04 to $.31, depending on the
health of the bank, as a result of the recapitalization of the BIF. On
November 15, 1995, the FDIC voted to drop its premiums for well capitalized
banks to zero effective January 1, 1996. Other banks will be charged
risk-based premiums up to $.27 per $100 of deposits. ACB and CIB pay the
minimum required premiums as a result of its "well capitalized" status.

         Congress passed in 1996 and the President signed into law,
provisions to strengthen the Savings and Loan Insurance Fund ("SAIF") and to
repay outstanding bonds that were issued to recapitalize the SAIF as a result
of payments made due to the insolvency of savings and loan associations and
other federally insured savings institutions in the late 1980s and early
1990s. The new law requires saving and loan associations to be bear the cost
of recapitalizing the SAIF and, after January 1, 1997, banks will contribute
towards paying off the financing bonds, including interest. Effective January
1, 1997, SAIF-insured institutions pay 3.2 cents per $100 in domestic
deposits, and BIF-insured institutions, like ACB, pay 0.64 cents per $100 in
domestics deposits. In 2000, banking industry will share on a more equal
basis in the bulk of the payments.

         FINANCIAL MODERNIZATION LEGISLATION

   
         Various proposals to adopt comprehensive financial modernization 
legislation have been introduced in Congress which include, among other 
things, elimination of the federal thrift charter, creation of a uniform 
financial institutions charter, expansion of bank powers, and integration of 
banking, commerce, securities activities and insurance. Under the proposed 
legislation, bank holding companies would be allowed to control both a 
commercial bank and a securities affiliate, which could engage in the full 
range of investment banking activities, including corporate underwriting. In 
May, the House passed legislation that would overhaul the financial service 
industry and allow mergers among banking, securities and insurance firms.   
Congress adjourned without the passage of similar legislation by the Senate.  
It is anticipated that substantially similar legislation will be considered 
in the next session of Congress.
    


                                      152

<PAGE>

         INTERSTATE BANKING AND BRANCHING

         On September 29, 1994, the President signed into law the Riegel-Neal
Interstate Banking and Branching Efficiency Act of 1994 (the "Interstate
Act"). Under the Interstate Act, beginning one year after the date of
enactment, a bank holding company that is adequately capitalized and managed
may obtain approval under Bank Holding Company Act to acquire an existing
bank located in another state without regard to state law. A bank holding
company would not be permitted to make such an acquisition if, upon
consummation, it would control (a) more than 10% of the total amount of
deposits of insured depository institutions in the United States or (b) 30%
or more of the deposits in the state in which ACB is located. A state may
limit the percentage of total deposits that may be held in that state by any
one bank or bank holding company if application of such limitation does not
discriminate against out-of-state banks. An out-of-state bank holding company
may not acquire a state bank in existence for less than a minimum length of
time that may be prescribed by state law except that a state may not impose
more than a five-year existence requirement.

         The Interstate Act also permits, beginning June 1, 1997, mergers of
insured banks located in different states and conversion of the branches of
the acquired bank into branches of the resulting bank. Each state may permit
such combinations earlier than June 1, 1997, and may adopt legislation to
prohibit interstate mergers after that date in that state or in other states
by that state's banks. The same concentration limits discussed in the
preceding paragraph apply. The Interstate Act also permits a national or
state bank to establish branches in a state other than its home state if
permitted by the laws of that state, subject to the same requirements and
conditions as for a merger transaction.

         In 1995, California adopted "opt in" legislation under the
Interstate Act that permits out-of-state banks to acquire California banks
that satisfy a five-year minimum age requirement (subject to exceptions for
supervisory transactions) by means of merger or purchases of assets, although
entry through acquisition of individual branches of California institutions
and de novo branching into California are not permitted. The Interstate Act
and the California branching statute will likely increase competition from
out-of-state banks in the markets in which Americorp operates, although it is
difficult to assess the impact that such increased competition may have on
Americorp's operations.Interstate Act may increase competition in Americorp's
market areas especially from larger financial institutions and their holding
companies. It is difficult to assess the impact such likely increased
competition may have on Americorp's operations.

         COMMUNITY REINVESTMENT ACT AND FAIR LENDING DEVELOPMENTS

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


                                      153

<PAGE>

         In 1995 the federal banking agencies issued final regulations which
change the manner in which they measure a bank's compliance with CRA
obligations. The final regulations adopt a performance-based evaluation
system which bases CRA ratings on an institution's actual lending, service
and investment performance, rather than the extent to which the institution
conducts needs assessments, documents community outreach activities or
complies with other procedural requirements.

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

         In connection with its assessment of CRA performance, the
appropriate bank regulatory agency assigns a rating of "outstanding,"
"satisfactory," "needs to improve" or "substantial noncompliance." At its
last examination by the FDIC, ACB received a CRA rating of "Satisfactory."

         POTENTIAL ENFORCEMENT ACTIONS

         Commercial banking organizations and bank holding companies, such as
ACB and Americorp, may be subject to potential enforcement actions by federal
and state bank regulatory officials for unsafe or unsound practices in
conducting their businesses or for violations of any law, rule, regulation or
any condition imposed in writing by the agency or any written agreement with
the agency. Enforcement actions may include the imposition of a conservator
or receiver, the issuance of a cease and desist order that can be judicially
enforced, the termination of insurance of deposits (in the case of a
depository institution), the imposition of civil money penalties, the
issuance of directives to increase capital, the issuance of formal and
informal agreements, the issuance of removal and prohibition orders against
institution-affiliated parties and the enforcement of such actions through
injunctions or restraining orders based upon a judicial determination that
the agency would be harmed if such equitable relief was not granted. Neither
Americorp nor ACB is a party to any such enforcement action.

                  INFORMATION CONCERNING AMERICORP MEETING ONLY

         In connection with its obligations under the Agreement to grant
substitute options to certain officers and directors of CIB (see "THE MERGER
- -Treatment of Stock Options"), Americorp, after consultation with CIB,
concluded that the adoption of a new stock option plan was more practical and
better fitted the future needs of Americorp than amending the current
Americorp stock option plan. This new stock option plan is referred to as the
"1998 Plan." If for any reason the Merger is not carried out, the 1998 Plan
will not become effective.

         SUMMARY OF THE 1998 PLAN

   
         On October 22, 1998 the Board of Directors of Americorp
adopted and approved, subject
    


                                      154

<PAGE>

   
to shareholder approval, the 1998 Plan to provide that employees, employee 
directors, non-employee directors and consultants will be eligible to receive 
options to purchase shares of Americorp Stock. Substitute options will also 
be granted pursuant to the Merger from the 1998 Plan. See "THE MERGER 
- -Treatment of Stock Options." The 1998 Plan  will supersede the current stock 
option plans of Americorp (which will be terminated as part of the Merger)  
but will not effect any of the stock options granted under such plans which 
will  remain outstanding.
    
   
         The 1998 Plan provides for the participation of directors and 
consultants as well as employees and officers. The Board of Directors 
believes that a stock option program is an important factor in retaining, 
motivating and attracting key employees and directors. It also believes that 
such plans provide incentives for high levels of performance and encourage 
stock ownership in Americorp.
    

         THE FOLLOWING DESCRIPTION OF THE 1998 PLAN IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE 1998 PLAN WHICH IS ATTACHED
HERETO AS APPENDIX E AND WHICH YOU ARE URGED TO READ AND CONSIDER CAREFULLY.

         PURPOSE

   
         The purpose of the 1998 Plan is to strengthen Americorp by providing 
to participating employees and officers ("Employees"), employee directors 
("Employee Directors"), non-employee directors ("Non-Employee Directors")and 
consultants,  business associates or other persons or entities with an 
important business relationship with Americorp ("Consultants") added 
incentive for high performance and to encourage stock ownership in Americorp. 
The 1998 Plan seeks to accomplish these goals by a means whereby such 
Employees, Employee Directors, Non-Employee Directors and Consultants of 
Americorp may be given an opportunity to purchase, by way of option, 
Americorp Stock. The 1998 Plan is also intended to enable Americorp to 
compete effectively for and retain the services of such persons and to 
provide incentives for such persons to exert maximum efforts for the success 
of Americorp
    

         Americorp intends that the options issued under the 1998 Plan shall,
in the discretion of the committee which administers the 1998 Plan, be either
incentive stock options ("Incentive Stock Options") as that term is used in
Section 422A of the Internal Revenue Code of 1986, as amended (the "Code"),
or any successor thereto, or options which do not qualify as incentive
stock options ("Non-Qualified Stock Options").

         ADMINISTRATION

         A committee of directors, appointed by the Board of Directors and
composed of not less than three "disinterested members," will administer the
1998 Plan (the "Committee"). The Committee shall have full power and
authority in its discretion to take any and all action required or permitted
to be taken under the 1998 Plan, including the selection of participants to
whom stock options may be granted, the determination of the number of shares
which may be covered by stock options, the purchase price, and other terms
and conditions thereof.

         SHARES RESERVED
   
         There are 110,000 shares of Americorp Stock reserved for
issuance upon exercise of options granted under the 1998 Plan. If any option
granted under the 1998 Plan shall for any reason expire, be canceled or
otherwise terminate without having been exercised in full, the shares not
purchased under such option shall again become available for the 1998 Plan.
    

         ELIGIBILITY
   
         All Employees, Employee Directors, Non-Employee Directors and 
Consultants are eligible to participate in the 1998 Plan and Employees and 
Employee Directors are eligible to receive Incentive and Non-Qualified Stock 
Options. Non-Employee Directors and Consultants are only eligible to receive 
Non-Qualified Stock Options. Americorp may issue Incentive Stock Options 
provided that the aggregate fair market value (determined at the time the 
Incentive Stock Option is granted) of the stock with respect to which 
Incentive Stock Options are exercisable for the first time by the optionee 
during any calendar year shall not exceed $100,000. Should it be determined 
that any Incentive Stock Option granted pursuant to the 1998 Plan exceed such 
maximum, such Incentive Stock Option shall be considered to be a 
Non-Qualified Stock Option and not qualify for treatment as an Incentive 
Stock Option under Section 422A of the Code to the extent, but only to the 
extent, of such excess.
    

         OPTION PRICE

         The exercise price of each option shall be determined by the
Committee and shall not be less than the fair market value of the stock
subject to the option on the date the option is granted; provided, however,
that the purchase price of the stock subject to an Incentive Stock Option may
not be less than 110% of such fair market value where the optionee owns (or
is deemed to own pursuant to the Code) shares of stock representing more than
10% of total combined voting power of all classes of stock of Americorp. The
purchase price of Americorp Stock acquired pursuant to an option shall be
paid in cash at the time the option is exercised or other shares of Americorp
Stock in partial or full payment. In such event, the stock being tendered as
payment shall be valued at its then-current fair market value.

         SUBSTITUTE OPTIONS

         The 1998 Plan provides for the grant of substitute options in the
event of certain acquisitions by Americorp or its affiliates. The terms under
which the substitute stock options are to be granted pursuant to the Merger
is discussed in "THE MERGER - Treatment of Stock Options."

         ADJUSTMENTS UPON CHANGES IN STOCK

         If the outstanding shares of Americorp Stock are increased,
decreased, or changed into, or exchanged for a different number or kind of
shares or securities of Americorp without receipt of consideration by
Americorp, through reorganization, merger, recapitalization,
reclassification, stock split,


                                      156

<PAGE>

stock dividend, stock consolidation, or otherwise, an appropriate and
proportionate adjustment shall be made in the number and kind of shares as to
which options may be granted. A corresponding adjustment changing the number
or kind of shares and the exercise price per share allocated to unexercised
options, or portions thereof, which shall have been granted prior to any such
change shall likewise be made. Any such adjustment, however, in an
outstanding option shall be made without change in the total price applicable
to the unexercised portion of the option but with a corresponding adjustment
in the price for each share subject to the option adjustments shall be made
by the Committee whose determination as to what adjustments shall be made,
and the extent thereof, shall be final and conclusive. No fractional shares
of stock shall be issued under the 1998 Plan on account of any such
adjustment.

         EXPIRATION, TERMINATION AND TRANSFER OF OPTIONS

         No option under the 1998 Plan may extend more than ten (10) years
from the date of grant. Notwithstanding the foregoing, any Incentive Stock
Option granted to an optionee who owns (or is deemed to own pursuant to the
Code) shares of stock representing more than ten percent (10%) of the total
combined voting power of all classes of stock of Americorp or any of its
affiliates shall expire not later than five (5) years from the date of grant.
For purposes of the 1998 Plan the date of grant of an option shall be the
date on which the Committee takes final action approving the award of the
option, notwithstanding the date the optionee accepts the option, the date of
execution of the option agreement, or any other date with respect to such
option.

         Except in the event of termination of employment due to death,
disability or termination for cause, options will terminate three months
after an Employee or Employee Director optionee ceases to be employed by
Americorp or its subsidiaries or a Non-Employee Director optionee ceases to
serve as a director of Americorp or its subsidiaries unless the options by
their terms were scheduled to terminate earlier. During that three month
period after the Employee or Employee Director optionee ceases to be employed
by Americorp or its subsidiaries, or a Non-Employee Director optionee ceases
to serve as a director of Americorp or its subsidiaries, such options shall
be exercisable only as to those shares with respect to which installments, if
any, had accrued as of the date on which the optionee ceased to be employed
by Americorp or its subsidiaries or ceased to serve as director of the
Corporation or its subsidiaries. If such termination was due to such
optionee's permanent and total disability, or such optionee's death, the
option, by its terms, may be exercisable for one year after such termination
of employment or cessation of directorship. If the Employee or Employee
Director optionee's employment is terminated for "just cause," the option
terminates immediately. An option by its terms may only be transferred by
will or by laws of descent and distribution upon the death of the optionee,
shall be transferable during the optionee's lifetime only pursuant to a
qualified domestic relations order or pursuant to a guardianship or
conservatorship for the benefit of an optionee, and shall be exercisable
during the lifetime of the person to whom the option is granted only by such
person.

         TERMINATION AND AMENDMENT OF THE 1998 PLAN

         The 1998 Plan will terminate upon the occurrence of a terminating
event, including, but not


                                      157

<PAGE>

limited to, liquidation, reorganization, merger or consolidation of Americorp
with another corporation in which Americorp is not the surviving corporation,
or a sale of substantially all the assets of Americorp to another person, or
a tender offer or acquisition by one person or a group of persons acting in
concert of more than 50% of Americorp Stock (a "Terminating Event"). The
Committee shall notify each optionee not less than thirty (30) days prior
thereto of the pendency of a Terminating Event. Upon the delivery of such
notice, any option outstanding shall, notwithstanding any vesting schedule
contained in an option agreement, become fully exercisable. The Board of
Directors may also suspend or terminate the 1998 Plan at any time. Unless
sooner terminated, the 1998 Plan shall terminate ten (10) years from the
effective date of the 1998 Plan. No options may be granted under the 1998
Plan while it is suspended or after it is terminated. Rights and obligations
under any option granted pursuant to the 1998 Plan while it is in effect
shall not be altered or impaired by suspension or termination of the 1998
Plan, other than pursuant to the terms thereof, except with the consent of
the person to whom the stock option was granted.

          The 1998 Plan may be amended by the Board of Directors at any time,
and from time to time. However, except as otherwise provided in the 1998 Plan
relating to adjustments upon changes in stock (e.g., stock splits or stock
dividends), no amendment shall be effective unless approved by the
affirmative vote of a majority of the shares of Americorp represented and
voting, within twelve (12) months before or after the adoption of the
amendment, if the amendment will: (a) increase the number of shares reserved
for options under the 1998 Plan; (b) materially modify the requirements as to
eligibility for participation in the 1998 Plan; or (c) materially increase
the benefits accruing to participants under the 1998 Plan.

          FEDERAL INCOME TAX CONSEQUENCES

          The following discussion is only a summary of the principal federal
income tax consequences of the options and rights to be granted under the
1998 Plan and is based on existing federal law (including administrative
regulations and rulings) which is subject to change, in some cases
retroactively. This discussion is also qualified by the particular
circumstances of individual optionees, which may substantially alter or
modify the federal income tax consequences herein discussed.

         Generally under present law, when an option qualifies as an
Incentive Stock Option under Section 422A of the Code: (a) an Employee will
not realize taxable income either upon the grant or the exercise of the
option, (b) any gain or loss upon a qualifying disposition of the shares
acquired by the exercise of the option will be treated as capital gain or
loss, and (c) no deduction will be allowed to Americorp for federal income
tax purposes in connection with the grant or exercise of an Incentive Stock
Option or a qualifying disposition of the shares. A disposition by an
Employee of stock acquired upon exercise of an Incentive Stock Option will
constitute a qualifying disposition if it occurs more than two years after
the grant of the option, and one year after the transfer of the shares to the
Employee. If such stock is disposed of by the Employee before the expiration
of those time limits, the transfer would be a "disqualifying disposition" and
the Employee, in general, will recognize ordinary income

                                      158

<PAGE>

equal to the lesser of (a) the aggregate fair market value of the shares as
of the date of exercise less the option price, or (b) the amount realized on
the disqualifying disposition less the option price. Ordinary income from a
disqualifying disposition will constitute compensation to the Employee.

         Upon the exercise of an Incentive Stock Option, the difference
between the fair market value of stock on the date of exercise and the option
price generally is treated as a "tax preference" item in that taxable year
for alternative minimum tax purposes, as are a number of other items
specified by the Code. Such tax preference items (with adjustments) form the
basis for the alternative minimum tax, which may apply depending on the
amount of the computed "regular tax" of the employee for that year. Under
certain circumstances the amount of alternative minimum tax is allowed as a
carry forward credit against regular tax liability in subsequent years.

         In the case of stock options which do not qualify as an Incentive
Stock Option (Non-Qualified Stock Options), no income generally is recognized
by the optionee at the time of the grant of the option. Under present law the
optionee generally will recognize ordinary income at the time the
Non-Qualified Stock Option is exercised equal to the aggregate fair market
value of the shares acquired less the option price. Notwithstanding the
foregoing, if the shares received upon exercising a Non-Qualified Stock
Option are subject to certain restrictions, the taxable event is postponed
until the restrictions lapse.

         Shares acquired upon exercise of Non-Qualified Stock Option will
have a tax basis equal to their market value on the exercise date or other
relevant date on which ordinary income is recognized and the holding period
for the shares generally will begin on the date of exercise or such other
relevant date. Upon subsequent disposition of the shares, the optionee
generally will recognize capital gain or loss provided the shares are held by
the optionee for more than one year prior to disposition.

         Americorp generally will be entitled to a deduction equal to the
ordinary income recognized by the optionee in the case of a disqualifying
disposition of an Incentive Stock Option or in connection with the exercise
of a Non-Qualified Stock Option.

         VOTE REQUIRED

         Approval of the 1998 Plan requires the affirmative vote of a
majority of the outstanding shares of Americorp Stock.

         The Board of Directors has approved the 1998 Plan and recommends
that the shareholders vote FOR the approval of the 1998 Plan.

                           INDEPENDENT AUDITORS' REPORT




Board of Directors and Stockholders
Channel Islands National Bank
Oxnard, California


We have audited the accompanying balance sheets of Channel Islands National
Bank as of December 31, 1997 and 1996, and the related statements of income,
changes in stockholders' equity and cash flows for the years then ended.
These financial statements are the responsibility of the management of the
Bank.  Our responsibility is to express an opinion on these financial
statements based on our audit.

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

In our opinion, based on our audits, the financial statements referred to in
the first paragraph present fairly, in all material respects, the financial
positions of Channel Islands National Bank as of December 31, 1997 and 1996,
and the results of its operations and its cash flows for the years then ended
in conformity with generally accepted accounting principles.

                        NOTES TO FINANCIAL STATEMENTS

                 FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1996



NOTE #1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accounting and reporting policies of Channel Islands National Bank (the
Bank) are in accordance with generally accepted accounting principles and
conform to practices within the banking industry.  The following are
descriptions of the more significant of those policies.

USE OF ESTIMATES - The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date
of the financial statements and the reported amounts of revenues and expenses
during the reporting period.  Actual results could differ from those
estimates.

Estimates that are particularly susceptible to significant change relate to
the determination of the allowance for losses on loans and the valuation of
real estate acquired in connection with foreclosures or in satisfaction of
loans.  In connection with the determination of the allowances for losses on
loans and foreclosed real estate, management obtains independent appraisals
for significant properties.

While management uses available information to recognize losses on loans and
foreclosed real estate, future additions to the allowances may be necessary
based on changes in local economic conditions.  In addition, regulatory
agencies, as an integral part of their examination process, periodically
review the Bank's allowances for losses on loans and foreclosed real estate.
Such agencies may require the Bank to recognize additions to the allowances
based on their judgments about information available to them at the time of
their examination.  Because of these factors, it is possible that the
allowances for losses on loans and foreclosed real estate may change.

INVESTMENT SECURITIES - The Bank adopted SFAS No. 115, "Accounting for
Certain Investments in Debt and Equity Securities," which addresses the
accounting for investments in equity securities that have readily
determinable fair values and for investments in all debt securities.
Pursuant to SFAS No. 115, securities are classified in three categories and
accounted for as follows: Debt securities that the Bank has the positive
intent and ability to hold to maturity are classified as held-to-maturity and
are measured at amortized cost; debt and equity securities bought and held
principally for the purpose of selling in the near term are classified as
trading securities and are measured at fair value, with unrealized gains and
losses included in earnings; debt and equity securities not classified as
either held-to-maturity or trading securities are deemed as
available-for-sale and are measured at fair value, with unrealized gains and
losses, net of applicable taxes, reported in a separate component of
stockholders equity.

                        NOTES TO FINANCIAL STATEMENTS

                 FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1996


NOTE #1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

LOANS - Loans are stated at amounts advanced less payments collected.  Interest
is calculated using the simple-interest method on all loans not discounted.
Unearned discounts on applicable installment loans are recognized as income over
the term of the loans by the sum-of-the-month-digits method (Rule of 78's).
Accrual of interest on a loan is generally discontinued when the loan becomes 90
days past due as to principal or interest (unless the loan is well secured and
in the process of collection) or when, in management's opinion, the full and
timely collection of principal or interest becomes uncertain.

The Bank adopted SFAS No. 114 (as amended by SFAS No. 118), "Accounting by
Creditors for Impairment of a Loan."  The statement generally requires those
loans identified as "impaired" to be measured on the present value of
expected future cash flows discounted at the loan's effective interest rate,
except that as a practical expedient, a creditor may measure impairment based
on a loan's observable market price, or the fair value of the collateral if
the loan is collateral dependent.  A loan is impaired when it is probable the
creditor will not be able to collect all contractual principal and interest
payments due in accordance with the terms of the loan agreement.

Loans are placed on nonaccrual when a loan is specifically determined to be
impaired or when principal or interest is delinquent for 90 days or more.
Any unpaid interest previously accrued on those loans is reversed from
income. Interest income generally is not recognized on specific impaired
loans unless the likelihood of further loss is remote.  Interest payments
received on such loans are applied as a reduction of the loan principal
balance.

Loan origination fees and certain direct loan origination costs are deferred
and amortized over the life of related loans as yield adjustments.

LOANS HELD FOR SALE - Loans held for sale are recorded at the lower of cost
or market.

ALLOWANCE FOR LOAN AND LEASE LOSSES - The allowance for loan losses is
established through provisions for loan losses which are included in the
accompanying statements of income.  Loans are charged against the allowance
for loan losses when management determines that collectibility of the
principal is unlikely.  Recoveries on loans previously charged off are
credited to the allowance. The accompanying financial statements require the
use of management estimates to calculate the allowance for loan losses.
These estimates are inherently uncertain and depend on the outcome of future
events.  Management's estimates are based upon previous loan loss experience,
current economic conditions, volume, growth and composition of the loan
portfolio, the value of collateral, and other relevant factors.

                 FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1996

NOTE #1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

OTHER REAL ESTATE OWNED - Other real estate owned represents real estate
acquired through foreclosure, and is carried at the lower of fair market
value less estimated selling cost or the loan balance at time of foreclosure.
Any valuation adjustments required at the time of foreclosure are charged to
the allowance for loan losses.  Any subsequent valuation adjustments,
operating expenses or income and gains and losses on disposition of such
properties are recognized in current operations.

PREMISES AND EQUIPMENT - Premises and equipment are stated at cost, less
accumulated depreciation and amortization.  Depreciation is computed using
the straight-line method over the estimated useful lives of the assets, which
range from five to ten years.  Leasehold improvements are amortized over the
shorter of the estimated useful lives of the improvements or the terms of the
leases.

INCOME TAXES - Provisions for income taxes are based on amounts reported in
the statements of income (after exclusion of non-taxable income such as
interest on state and municipal securities) and include deferred taxes on
temporary differences in the recognition of income and expense for tax and
financial statement purposes.  Deferred taxes are computed on the liability
method as prescribed in SFAS No. 109, ACCOUNTING FOR INCOME TAXES.

LOAN SALES AND SERVICING - Gains and losses from the sale of participating
interests in loans guaranteed by the Small Business Administration (SBA) are
recognized based on the premium received or discount paid and the cost basis
of the portion of the loan sold.  The cost basis of the portion of the loan
sold is obtained by allocating the total cost of each loan between the
guaranteed portion of the loan sold and the unguaranteed portion of the loan
retained, based on their relative fair values.  The book value allocated to
the unguaranteed portion of the loan, if less than the principal amount, is
recorded as a discount on the principal amount retained.  The discount is
accreted to interest income over the remaining estimated life of the loan.
The Bank retains the servicing on the portion of the loans sold and
recognizes income on the servicing fees that are received.  During 1997 the
Bank sold all loan servicing rights; the gain is reflected in the Statements
of Income as other income.

EARNINGS PER SHARE (EPS)

Basic EPS excludes dilution and is computed by dividing income available to
common stockholders by the weighted-average number of common shares
outstanding for the period.  Diluted EPS reflects the potential dilution that
could occur if securities or other contracts to issue common stock were
exercised or converted into common stock or resulted in the issuance of
common stock that then shared in the earnings of the entity.

                 FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1996

NOTE #1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

STATEMENTS OF CASH FLOWS - For purposes of reporting cash flows, cash and
cash equivalents include cash and due from banks and federal funds sold.
Generally, federal funds are sold for one-day periods.  Certain cash flows
associated with loans and customer deposits have been reported net.

RECLASSIFICATIONS - Certain reclassifications have been made to the 1996
financial statements to conform to the 1997 classifications.

NOTE #2 - RESERVE REQUIREMENTS

All depository institutions are required by law to maintain reserves on
transaction accounts.  These reserves can be in the form of balances at the
Federal Reserve Bank or in cash held by the Bank.  The average reserve
requirement for the Bank was $748,000 in 1997, and $633,000 in 1996.

NOTE #3 - INVESTMENT SECURITIES

At December 31, 1997, the investment securities portfolio was comprised of
securities classified as available-for-sale and held-to-maturity in
conjunction with the adoption of SFAS 115, resulting in investment securities
available for sale being carried at market value and investment securities
held to maturity being carried at cost, adjusted for amortization of premiums
and accretions of discounts.

The amortized cost and fair values of investment securities available-for-sale
at December 31, 1997, were:

NOTE #6 - STOCK OPTION PLAN

At December 31, 1997, the Bank had an incentive stock option plan which is
described below.  The Bank applies APB Opinion 25 and related interpretations in
accounting for its plan.  Accordingly, no compensation cost has been recognized
for its fixed stock option plan.  Had compensation costs for these plans been
determined based on the fair value at the grant dates consistent with the method
of SFAS 123, the impact would not have materially affected net income.

In 1985, the Bank adopted a stock option plan under which the Bank's Common
shares may be issued to officers and key employees at not less than 100 percent
of fair market value at the date the options were granted.

NOTE #6 - STOCK OPTION PLANS, CONTINUED

The fair value of each option granted was estimated on the date of grant
using the Black-Scholes option-pricing model with the following assumptions
for 1996; risk-free rate of 6.23 percent, dividend yield of 0 percent,
volatility of 18.10 percent, and expected life of 5.9 years.

The Bank has an incentive stock-option plan which provides for the issuance
of up to 110,000 shares of the Bank's authorized but unissued common stock to
officers and directors.  Options are granted at a price not less than the
fair market value of the stock at the date of grant (not less than 110
percent of fair market value if the option is granted to a person owning more
than 10 percent of the voting power of the Bank's stock) and expire no later
than fourteen years from the date of grant.  Information concerning stock
options is summarized as follows:

loan and lease losses, OREO valuation allowance, state taxes, and recognition
of prepaid expenses for tax.

NOTE #9 - COMMITMENTS

The Bank leases its current facilities in Oxnard and Camarillo under
operating leases with lease terms expiring through 2012.  The Camarillo
branch facility lease agreement includes an option to extend the lease for an
additional five-year period with future rentals to be determined based on the
change in a specified inflation index.  Future minimum commitments under
these leases are as follows:

</TABLE>

Rent expense was $274,560 in 1997, and $268,506 in 1996.

The Bank is a party to financial instruments with off-balance-sheet risk in
the normal course of business to meet the financing needs of its customers.
These financial instruments include commitments to extend credit and standby
letters of credit.  These instruments involve, to varying degrees, elements
of credit and interest rate risk in excess of the amount recognized in the
balance sheet. The Bank's exposure to credit loss in the event of
nonperformance by the other party to the financial instrument for commitments
to extend credit and standby letters of credit is represented by the
contractual amount of those instruments. At December 31, 1997, the Bank had
commitments to extend credit of approximately $9,989,056 and obligations
under standby letters of credit of approximately $795,163.

Commitments to extend credit are agreements to lend to a customer as long as
there is no violation of any condition established in the contract.
Commitments generally have fixed expiration dates or other termination
clauses and may require payment of a fee.  Since many of the commitments are
expected to expire without being drawn upon, the total commitment amounts do
not necessarily represent future cash requirements.

Standby letters of credit are conditional commitments issued by the Bank to
guarantee the performance of a customer to a third party.  Those guarantees are
primarily issued to support public and private borrowing arrangements, including
commercial paper, bond financing, and similar transactions.  Generally, the Bank
issues standby letters of credit for one year, which are reviewed annually for
renewal.

              FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1996

NOTE #9 - COMMITMENTS, CONTINUED

The Bank uses the same credit policies in making commitments and conditional
commitments as it does for extending loan facilities to customers.  The Bank
evaluates each customer's creditworthiness on a case-by-case basis.  The
amount of collateral obtained, if deemed necessary by the Bank upon extension
of credit, is based on management's credit evaluation of the counterparty.
Collateral held varies but may include certificates of deposit, marketable
securities, accounts receivable, inventory, property, plant and equipment,
and real estate.

At December 31, 1997, the Bank had a line of credit with a correspondent bank
totaling $2,000,000.  There were no borrowings under this line of credit at
December 31, 1997 or 1996.

NOTE #10 - MORTGAGE LOAN SERVICING OPERATIONS

The Bank originated long-term first and second trust deed mortgages for
resale on the Secondary Market to Federal Home Loan Mortgage Corporation
(FHLMC) and Federal National Mortgage Association (FNMA).  The gains or
losses on the sales of these loans were generally recognized at the time of
sale.  The Bank retained servicing rights to these loans.  Servicing
arrangements provided for the Bank to maintain all records related to the
servicing agreement, to assume responsibility for billing mortgagors, to
collect periodic mortgage payments, and to perform various other activity
necessary to the mortgage servicing function.  The Bank receives as
compensation a servicing fee on the principal balance of the outstanding
loans.  Servicing fee income amounted to approximately $124,122 and $136,629
in 1997 and 1996, respectively.  During 1997, the Bank sold the servicing
rights on loans totaling approximately $54 million.  The mortgage servicing
rights were sold without recourse.  The Bank received approximately $492,000
from the sale which represents approximately 90 percent of the proceeds from
the sale.  The Bank will receive the balance of the proceeds in 1998.

NOTE #11 - REGULATORY MATTERS

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

Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum amounts and ratios (set forth in the table
below) of total and Tier 1 capital (as defined in the regulations) to
risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average
assets (as defined).  Management believes, as of December 31,1997, that the Bank
meets all capital adequacy requirements to which it is subject.

NOTE #11 - REGULATORY MATTERS, CONTINUED

As of December 31,1997, the most recent notification from the Office of the
Comptroller of the Currency (OCC) categorized the Bank as well capitalized
under the regulatory framework for prompt corrective action (there are no
conditions or events since that notification that management believes have
changed the Bank's category).  To be categorized as well-capitalized, the
Bank must maintain minimum ratios as set forth in the table below.  The
following table also sets forth the Bank's actual capital amounts and ratios
(dollar amounts in thousands):

NOTE #12 - DEFINED CONTRIBUTION PLAN

Effective September 1, 1994, the Bank established a qualified defined
contribution plan [401(K) Retirement Savings Plan] for all eligible
employees. Employees may contribute from 1 percent to 15 percent of their
compensation with a maximum of $9,500 annually.  The Bank's contributions to
the plan are a monthly, discretionary amount, which may vary from
month-to-month.  The Bank's matching contribution will become vested at 60
percent after three years, 80 percent after four years, with full vesting
after five years.  The expense was $24,941 and $14,780 for the years ended
December 31, 1997 and 1996, respectively.

</TABLE>

The Bank in estimating fair value disclosures used the following methods and
assumptions:

CASH AND CASH EQUIVALENTS - The carrying amounts reported in the balance sheet
for cash and cash equivalents approximate those assets' fair values due to the
short-term nature of the assets.

SECURITIES AND MONEY MARKET INVESTMENTS - Fair values are based upon quoted
market prices, where available.

LOANS - For variable rate loans that reprice frequently and with no
significant change in credit risk, fair values are based on carrying values.
Fair values of residential mortgage loans are based on quoted market prices
of similar loans sold in conjunction with securitization transactions.  The
fair values for other loans are estimated using discounted cash flow analyses
using discount rates approximating the interest rates currently being offered
for loans with similar terms to borrowers of similar credit quality.  The
carrying amount of accrued interest receivable approximates its fair value.

NOTE #13 - FAIR VALUE OF FINANCIAL INSTRUMENTS, CONTINUED

DEPOSITS - The fair values for interest and noninterest-bearing demand
deposits, savings deposits, and money market savings are equal to their
carrying value. Fair values for fixed-rate certificates of deposit are
estimated using discount cash-flow calculations that apply interest rates
currently being offered on certificates, to a schedule of aggregated expected
monthly maturities on time deposits.  The intangible value of long-term
relationships with depositors is not taken into account in estimating the
fair values disclosed.  The carrying amount of accrued interest payable
approximates fair value.

OFF-BALANCE SHEET INSTRUMENTS - Fair values of loan commitments and financial
guarantees are based upon fees currently charged to enter similar agreements,
taking into account the remaining terms of the agreement and the
counterparties' credit standing.

NOTE #14 - NEW ACCOUNTING PRONOUNCEMENTS

In June 1997, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 130, "Reporting
Comprehensive Income". The statement which is effective for the year ending
December 31,1998, establishes standards of disclosure and financial statement
display for reporting comprehensive income and its components.

In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information". The statement changes current practice
under SFAS 14 by establishing a new framework on which to base segment
reporting (referred to as management approach) and requires certain related
disclosures about products and services, geographic areas and major
customers. The disclosures are required for the year ending December 31,1998.

     INDEPENDENT AUDITORS' REPORT

     To the Shareholders and Board of Directors
       of Americorp:

     We have audited the accompanying consolidated balance sheets of
Americorp and subsidiary (the "Company") as of December 31, 1997 and 1996 and
the related consolidated statements of income, stockholders' equity and cash
flows for each of the three years in the period ended December 31, 1997.
These financial statements are the responsibility of the Company's
management.  Our responsibility is to express an opinion on these financial
statements based on our audits.

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

     In our opinion, such consolidated financial statements present fairly,
in all material respects, the financial position of Americorp and subsidiary
at December 31, 1997 and 1996, and the results of their operations and their
cash flows for each of the three years in the period December 31, 1997 in
conformity with generally accepted accounting principles.

AMERICORP AND SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- -------------------------------------------------------------------------------

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accounting and reporting policies of Americorp and subsidiary (the
"Company") are in accordance with generally accepted accounting principles
and conform to practices within the banking industry.  The following are
descriptions of the more significant of those policies.

BASIS OF PRESENTATION - The consolidated financial statements include
Americorp and its wholly owned subsidiary, American Commercial Bank (the
"Bank").  All significant intercompany accounts and transactions have been
eliminated.

USE OF ESTIMATES - The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date
of the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

Material estimates that are particularly susceptible to significant change
relate to the determination of the allowance for loan losses, the valuation
of real estate acquired in connection with foreclosures or in satisfaction of
loans and the valuation allowance for deferred tax assets.

In connection with the determination of the allowance for losses on loans and
foreclosed real estate, management obtains independent appraisals for
significant properties.  While management uses available information to
recognize losses on loans and foreclosed real estate, future additions to the
allowances may be necessary based on changes in local economic conditions.
In addition, regulatory agencies, as an integral part of their examination
process, periodically review the Company's allowance for losses on loans and
foreclosed real estate. Such agencies may require the Company to recognize
additions to the allowances based on their judgements about information
available to them at the time of their examination.  Because of these
factors, it is reasonably possible that the allowances for losses on loans
and foreclosed real estate may change materially in the near future.

In connection with the determination of the valuation allowance for deferred
tax assets, management considers whether it is more likely than not that all
or part of the deferred tax asset will be realized. The amount of the
deferred tax asset considered realizable, however, could be reduced in the
near future for changes in certain assumptions or estimates used to calculate
future taxable income.

SECURITIES - The Company classifies its investment securities into three
categories as follows:

Trading Securities - Securities held principally for resale in the near
future are classified as trading securities and recorded at their fair
values.  The Company holds no securities that are classified as trading
securities.


                                       F-35

<PAGE>

Securities Held-to-Maturity - Securities for which the Company has the
positive intent and ability to hold to maturity are carried at cost,
increased by the accretion of discounts and decreased by the amortization of
premiums.  Discount is accreted and premium is amortized over the period to
maturity of the related security.

Securities Available-for-Sale - Securities available-for-sale consist of
investment securities not classified as trading securities nor as securities
held-to-maturity.  Securities available-for-sale are recorded at their fair
market values.  Unrealized holding gains and losses, net of tax, are reported
as a net amount in a separate component of equity until realized.  Gains and
losses are determined using the specific identification method.  The
accretion of discounts and the amortization of premiums are recognized in
interest income using the interest method over the period to maturity.

LOANS - Loans are stated at unpaid principal balances, less the allowance for
loan losses and net deferred loan fees and unearned discounts.

Loan origination and commitment fees, as well as certain direct origination
costs, are deferred and amortized as a yield adjustment over the lives of the
related loans using the interest method. Amortization of deferred loan fees
is discontinued when a loan is placed on nonaccrual status.

Loans are placed on nonaccrual when a loan is specifically determined to be
impaired or when principal or interest is delinquent for 90 days or more.
Any unpaid interest previously accrued on those loans is reversed from
income. Interest income generally is not recognized on specific impaired
loans unless the likelihood of further loss is remote.  Interest payments
received on such loans are applied as a reduction of the loan principal
balance.  Interest income on other nonaccrual loans is recognized only to the
extent of interest payments received.

The allowance for loan and lease losses is increased by provisions for loan
and lease losses which are included in the accompanying statements of income.
Losses are charged against the allowance for loan and lease losses when
management determines the collectibility of the principal is unlikely.
Recoveries on loans and leases previously charged off are credited to the
allowance.  Management's determination of the allowance is based on periodic
evaluations of the loan and lease portfolio which take into consideration
such factors as changes in the growth, size and composition of the loan and
lease portfolio, overall portfolio quality, prior loan and lease loss
experience, review of specific loans and leases, collateral, guarantees and
current economic conditions.

DIRECT FINANCING LEASES - Income from direct financing leases is recorded
over the life of the lease under the financing method of accounting.  The
investment includes the sum of aggregate rentals receivable and the estimated
residual value of leased equipment less deferred income.

PREMISES AND EQUIPMENT - Premises and equipment are stated at cost less
accumulated depreciation and amortization.  Depreciation is generally charged
to income over the estimated useful lives of the assets by use of the
straight-line method.  Leasehold improvements are amortized over the terms of
the leases or the estimated useful lives of improvements, whichever is
shorter.


                                       F-36

<PAGE>

Estimated useful lives are as follows:

Furniture, fixtures and equipment                        3 to 10 years
Leasehold improvements                                   5 to 15 years

OTHER REAL ESTATE OWNED - Real estate acquired through foreclosure or deed in
lieu of foreclosure is recorded at the lower of the outstanding loan balance
at the time of foreclosure or appraised value.  Gains and losses on the sale
of other real estate owned and write-downs resulting from periodic
revaluation of the property are charged to other operating expenses.

ADVERTISING COSTS - The Company expenses the costs of advertising when
incurred.

INCOME TAXES -  Deferred income taxes arise from temporary differences
between the tax basis of assets and liabilities and their reported amounts in
the financial statements.

EARNINGS PER SHARE - Earnings per common share are based on the weighted
average number of common shares outstanding.  Earnings per common share -
assuming dilution are based on the weighted average number of common and
equivalent shares outstanding. The average number of common shares
outstanding and common equivalent shares outstanding for 1997 were 577,719
and 665,649, respectively. The average number of common shares outstanding
and common equivalent shares outstanding for 1996 were 571,685 and 660,293,
respectively. The average number of common shares outstanding and common
equivalent shares outstanding for 1995 were 567,331 and 669,135,
respectively.  Common equivalent shares consist of the dilutive effect of
stock options using the treasury stock method.

STATEMENT OF CASH FLOWS - For purposes of reporting cash flows, cash and cash
equivalents include cash on hand, amounts due from banks, and Federal funds
sold.  Generally, Federal funds are sold for one-day periods.

2. SECURITIES

     The Company has a 50% limited partner interest in a another limited
partnership (Santa Paula Affordable Homes, Ltd.).  Affordable Communities,
Inc. is the general partner.  The partnership was originally formed to
construct a low-to-moderate income housing development in Santa Paula,
California.  Due to various factors, the development of the housing project
will not commence.  As a result, the partners are in the process of
dissolving the Santa Paula Affordable Homes, Ltd. partnership. The
partnership's operations to date have not been significant.  In connection
with the partnership agreement, the Company had purchased a parcel of land to
sell to Santa Paula Affordable Homes, Ltd.  The land was purchased in 1988
for $800,000. In December 1996, the Company wrote down the land to estimated
fair market value.  The write-down amounted to $200,000 and was based upon an
estimate of future discounted cash flows.  The land was then sold to a 50%
owner of Affordable Communities, Inc. for $600,000.  The Company financed
100% of the sale of the land.

8. PROFIT SHARING AND DEFERRED COMPENSATION PLANS

     Profit Sharing - The Company has a profit sharing and salary deferral
401(k) plan for the benefit of its employees.  Under the plan, eligible
employees may defer a portion of their salaries.  The Company may, at its
option, make matching contributions or profit sharing contributions. For
1997, 1996 and 1995, the Company matched 50% of the employees' deferral which
amounted to $17,031, $34,212 and $35,876, respectively.  No profit sharing
contributions were made in 1997, 1996 or 1995.  In lieu of a contribution to
the profit sharing plan, the Company accrued bonuses to its employees of
$305,563 in 1997 and $193,410 in 1995.  No bonuses were accrued in 1996.

<PAGE>

     Deferred Compensation, Directors and Chief Executive Officers -  In May
1997, the Company approved the Directors' Retirement Plan and the Chief
Executive Officer's Retirement Plan which restated and amended preexisting
retirement plans.  The original plans provided for payments upon retirement,
death or disability for the benefit of directors and the chief executive
officer (now a director) of the Company. The preexisting and the restated
plans are nonqualified and nonfunded plans. The preexisting plans had been
amended several times and as of January 1, 1997 provided for six years of
retirement benefits upon retirement.  Under the restated plans,  each
participant upon normal retirement, death, or disability will receive a
monthly retirement benefit for 120 months in an amount stipulated in the
agreement.  Any new participants shall vest 8% per year for services rendered
after a three year waiting period has expired.  The plans also provide for
reduced benefits upon early retirement.

     Deferred Compensation, Senior Officers - The Company has a nonqualified,
nonfunded income continuation plan providing for payments upon retirement,
death or disability of certain employees.  Under the plan, certain employees
will receive retirement payments equal to a portion of the last three years'
average compensation.  The payments are to be made monthly for a period of
ten years.  The plan also provides for reduced benefits upon early
retirement, disability or termination of employment.

     As of December 31, 1997 and 1996, the projected benefit obligation and
the net benefit liability of the plans are $1,698,863 and $1,599,281,
respectively, and are included in other liabilities in the accompanying
consolidated financial statements. Compensation expense relating to the plans
was $266,883, $403,397 and $219,250 in 1997, 1996 and 1995, respectively.

     In anticipation of the future obligation of the deferred compensation
plans, the Company has invested in life insurance policies which are carried
at cash surrender values of $2,254,886 and are included in other assets in
the accompanying consolidated financial statements. The Company's intention
is to partially fund these plans from the proceeds and investment earnings of
the insurance policies and from the profits derived from the limited
partnerships' operations (see Note 6).

     9. STOCK OPTION PLANS

     The Company has stock option plans which provide for the granting of
options to directors and officers to purchase stock at its market value on
the date the options are granted.  150,000 shares of common stock have been
reserved for the granting of these options. Options granted become
exercisable commencing from the date of a grant. For the participants who
have been employed by or directors with the Company less than ten years, not
more than 20% of the shares granted, plus shares left over from previous
years, can be exercised in any one year. For participants who have been
employed by or directors with the Company more than ten years, up to 100% can
be exercised during the first year, with the percentage decreasing by 20%
increments over the next four years.  At the end of the fifth year, the
options expire.

    In accordance with Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation" ("FAS 123"), which was effective as
of January 1, 1996, the fair value of option grants is estimated on the date
of grant using the Black-Scholes option-pricing model for proforma footnote

purposes with the following assumptions used for grants in all years;
dividend yield of 3.16%, risk-free interest rates of 5.723% to 6.296% and
expected option life of 3.91 years and 4.03 years for 1997 and 1996,
respectively. Expected volatility was assumed to be .0429 and .0525 for 1997
and 1996, respectively.

     As permitted by FAS 123, the Company has chosen to continue accounting
for stock options at their intrinsic value.  Accordingly, no compensation
expense has been recognized for its stock option compensation plans.  Had the
fair value method of accounting been applied to the Company's stock option
plans, the tax-effected impact would be as follows:

10. SIGNIFICANT CONCENTRATIONS OF CREDIT RISK

                                     F-44

<PAGE>

Most of the Company's business activity is with customers throughout its
primary market area of Ventura County, California.  The Company's loan
portfolio is well diversified and no significant industry concentrations exist.

     Investments in state and municipal securities involve governmental
entities within the State of California.  As of December 31, 1997, the
Company had $14,849,043 due from a correspondent bank in excess of federal
deposit insurance limits.

     11. POSTRETIREMENT BENEFIT PLANS OTHER THAN PENSIONS

     The Company provides health and life insurance benefits to retired
employees and directors.  Employees may become eligible for benefits if they
retire after attaining specified age and service requirements while they
worked for the Company.  Directors may become eligible after five years
regardless of their age at retirement.

     The Company implemented the provisions of Statement of Financial
Accounting Standards No. 106, "Employers' Accounting for Postretirement
Benefits Other Than Pensions" ("SFAS 106") effective January 1, 1996. These
benefits are now accrued over the period the employee provides services to
the Company.  Prior to the change, costs were charged to expense as incurred.
 The Company elected the delayed recognition treatment of the adoption of
SFAS 106.  Under this method, the transition obligation will be amortized on
a straight line basis over the remaining service period of active plan
participants.  The Company's current policy is to fund the cost of
postretirement health care and life insurance plans on a pay-as-you-go basis.

     The net periodic cost for postretirement health care and life insurance
benefits includes the following:

     The assumed discount rate and the assumed rate of increase in
compensation levels are 7.25% and 7.25%, respectively.  The assumed health
care cost trend rate used in measuring the accumulated postretirement benefit
obligation was 6% declining to 4.75% in 10 years.  If the health care cost
trend rate assumptions were increased by 1%, the accrued postretirement
benefit cost, as of December 31, 1997, would be increased by approximately
$22,732.

     12. REGULATORY MATTERS

     Capital requirements -- The Company is subject to various regulatory
capital requirements administered by the Federal banking agencies.  The
regulations require the Company to meet specific capital adequacy guidelines
that involve quantitative measures of the Company's assets, liabilities, and
certain off-balance-sheet items as calculated under regulatory accounting
practices.  The Company's capital classification is also subject to
qualitative judgements by the regulators about components, risk weighting,
and other factors.  Failure to meet minimum capital requirements can initiate
certain mandatory, and possibly additional discretionary, actions by
regulators that, if undertaken, could have a direct material effect on the
Company's financial statements.

     Quantitative measures established by regulation to ensure capital
adequacy require the Company to maintain minimum amounts and ratios (set
forth in the table below) of Tier 1 capital (as defined by the regulations)
to total average assets (as defined), and minimum ratios of Tier 1 and total
capital (as defined) to risk-weighted assets (as defined).  To be considered
adequately capitalized (as defined) under the regulatory framework for prompt
corrective action, the Company must maintain minimum Tier 1 leverage, Tier 1
risk-based, total risk-based ratios as set forth in the table.  The Company's
actual capital amounts and ratios are also presented in the table.

As of December 31, 1997 (in thousands):

     At December 31, 1997, the Company was obligated under operating leases
requiring annual rentals as follows:

                              ----------

</TABLE>

     Rental expense was $430,467, $367,376 and $376,426 in 1997, 1996 and
1995, respectively.

     At December 31, 1997, the Company had unused lines of credit with two
banks. The lines total $4,700,000, have variable interest rates based on the
lending bank's daily Federal funds rates, and are due on demand. The lines of
credit are unsecured.

     14. FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

     The Company is a party to financial instruments with off-balance-sheet
risk in the normal course of business to meet the financing needs of its
customers. These financial instruments include commitments to extend credit
and standby letters of credit.  These instruments involve, to varying
degrees, elements of credit and interest rate risk in excess of the amount
recognized in the statement of financial position.  Exposure to credit loss
in the event of nonperformance by the other party to commitments to extend
credit and standby letters of credit is represented by the contractual
notional amount of those instruments.  At December 31, 1997, the Company had
commitments to extend credit of $25,014,995 and obligations under standby
letters of credit of $125,715.

     Commitments to extend credit are agreements to lend to a customer as
long as there is no violation of any condition established in the contract.
Commitments generally have fixed expiration dates or other termination
clauses and may require payment of a fee.  Since many of the commitments are
expected to expire without being drawn upon, the total commitment amounts do
not necessarily represent future cash requirements.

                                     F-47

<PAGE>

    Standby letters of credit are conditional commitments issued by the
Company to guarantee the performance of a customer to a third party. Those
guarantees are primarily issued to support public and private borrowing
arrangements, including commercial paper, bond financing, and similar
transactions.

    The Company uses the same credit policies in making commitments and
conditional commitments as it does for extending loan facilities to
customers.  The Company evaluates each customer's credit-worthiness on a
case-by-case basis.  The amount of collateral obtained, if deemed necessary
upon extension of credit, is based on management's credit evaluation of the
counterparty.  Collateral held varies but may include accounts receivable,
inventory, property, plant, and equipment and real estate.

15. FAIR VALUE OF FINANCIAL INSTRUMENTS

    Financial Accounting Standards No. 107 ("FAS 107"), "Disclosures About
Fair Value of Financial Instruments" requires corporations to disclose the
fair value of its financial instruments, whether or not recognized in the
balance sheet, where it is practical to estimate that value.

     Fair value estimates made as of December 31, 1997 are based on relevant
market information about the financial instruments.  These estimates do not
reflect any premium or discount that could result from offering for sale at
one time the Company's entire holding of a particular financial instrument.
In cases where quoted market prices are not available, fair value estimates
are based on judgements regarding future expected loss experience, current
economic conditions, risk characteristics of various financial instruments,
and other factors.

     These estimates are subjective in nature and involve uncertainties and
matters of significant judgement and, therefore, cannot be determined with
precision. Changes in assumptions could significantly affect the estimates.
In addition, the tax ramifications related to the realization of the
unrealized gains and losses can have a significant effect on fair value
estimates and have not been considered in the estimates.

     The following methods and assumptions were used by the Company in
estimating its fair value disclosures for financial instruments:

     CASH AND CASH EQUIVALENTS - The carrying amounts reported in the balance
sheets for cash and short-term instruments approximate those assets' fair
values.

     SECURITIES - Fair values were based on quoted market prices, where
available. If quoted market prices were not available, fair values were based
on quoted market prices of comparable instruments.

     LOANS - The carrying values, reduced by estimated inherent credit
losses, of variable-rate loans and other loans with short-term
characteristics were considered fair values.  For other loans, the fair
market values were calculated by discounting scheduled future cash flows
using current interest rates offered on loans with similar terms adjusted to
reflect the estimated credit losses inherent in the portfolio.

                                     F-48

<PAGE>

     ACCRUED INTEREST RECEIVABLE AND ACCRUED INTEREST PAYABLE - The carrying
amounts reported in the balance sheets for accrued interest receivable and
accrued interest payable approximate their fair values.

     DEPOSIT LIABILITIES - The fair value of deposits with no stated
maturity, such as noninterest-bearing demand deposits, NOW, savings, and
money market deposits, was, by definition, equal to the amount payable on
demand as of December 31, 1997.  The fair value of certificates of deposit
was based on the discounted value of contractual cash flows, calculated using
the discount rates that equaled the interest rates offered at the valuation
date for deposits of similar remaining maturities.




     The following is a summary of the carrying amounts and estimated fair
values of the Company's financial assets and liabilities at December 31,
1997:

</TABLE>

     At December 31, 1997, the Bank had outstanding standby letters of credit
and commitments to extend credit.  These off-balance sheet financial
instruments are generally exercisable at the market rate prevailing at the
date the underlying transaction will be completed, and, therefore, they were
deemed to have no current fair market value (see Note 14).

     Fair value estimates are based on existing on- and off-balance sheet
financial instruments without attempting to estimate the value of anticipated
future business and the value of assets and liabilities that are not
considered financial instruments.  Significant assets and liabilities that
are not considered financial assets or liabilities include the discounted
value of fee revenues generated by the mortgage banking operation nor is the
value of deferred tax assets or premises and equipment considered.

17.  SUBSEQUENT EVENT


     On July 7, 1998, the Company and Channel Islands Bank ("CIB") signed a
definitive merger agreement.  The agreement calls for each share of CIB
common stock to be converted into Americorp common stock in accordance with
the exchange ratio set forth in the agreement. Consummation of the merger is
expected to occur during the last quarter of 1998, and is subject to various
conditions, including, but not limited to, approval by the stockholders of
the Company and CIB.

     It is expected that the merger will be accounted for under the pooling
of interests method and, accordingly, historical financial data in future
reports will be restated to include CIB data.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

     1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The accounting and reporting policies of Americorp and subsidiary (the
"Company") are in accordance with generally accepted accounting principles
and conform to practices within the banking industry.  The following are
descriptions of the more significant of those policies.

     BASIS OF PRESENTATION - The consolidated financial statements include
Americorp and its wholly owned subsidiary, American Commercial Bank (the
"Bank").  All significant intercompany accounts and transactions have been
eliminated.

     USE OF ESTIMATES - The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date
of the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

     Material estimates that are particularly susceptible to significant change
relate to the determination of the allowance for loan losses, the valuation of
real estate acquired in connection with foreclosures or in satisfaction of loans
and the valuation allowance for deferred tax assets.

     In connection with the determination of the allowance for losses on
loans and foreclosed real estate, management obtains independent appraisals
for significant properties.  While management uses available information to
recognize losses on loans and foreclosed real estate, future additions to the
allowances may be necessary based on changes in local economic conditions.
In addition, regulatory agencies, as an integral part of their examination
process, periodically review the Company's allowance for losses on loans and
foreclosed real estate. Such agencies may require the Company to recognize
additions to the allowances based on their judgements about information
available to them at the time of their examination.  Because of these
factors, it is reasonably possible that the allowances for losses on loans
and foreclosed real estate may change materially in the near future.

     In connection with the determination of the valuation allowance for
deferred tax assets, management considers whether it is more likely than not
that all or part of the deferred tax asset will be realized. The amount of
the deferred tax asset considered realizable, however, could be reduced in
the near future for changes in certain assumptions or estimates used to
calculate future taxable income.


                                     F-59

     SECURITIES - The Company classifies its investment securities into three
categories as follows:

     Trading Securities - Securities held principally for resale in the near
future are classified as trading securities and recorded at their fair
values. The Company holds no securities that are classified as trading
securities.

     Securities Held-to-Maturity - Securities for which the Company has the
positive intent and ability to hold to maturity are carried at cost,
increased by the accretion of discounts and decreased by the amortization of
premiums. Discount is accreted and premium is amortized over the period to
maturity of the related security.

     Securities Available-for-Sale - Securities available-for-sale consist of
investment securities not classified as trading securities nor as securities
held-to-maturity.  Securities available-for-sale are recorded at their fair
market values.  Unrealized holding gains and losses, net of tax, are reported
as a net amount in a separate component of equity until realized.  Gains and
losses are determined using the specific identification method.  The
accretion of discounts and the amortization of premiums are recognized in
interest income using the interest method over the period to maturity.

     LOANS - Loans are stated at unpaid principal balances, less the
allowance for loan losses and net deferred loan fees and unearned discounts.

     Loan origination and commitment fees, as well as certain direct
origination costs, are deferred and amortized as a yield adjustment over the
lives of the related loans using the interest method. Amortization of
deferred loan fees is discontinued when a loan is placed on nonaccrual status.

     Loans are placed on nonaccrual when a loan is specifically determined to
be impaired or when principal or interest is delinquent for 90 days or more.
Any unpaid interest previously accrued on those loans is reversed from
income. Interest income generally is not recognized on specific impaired
loans unless the likelihood of further loss is remote.  Interest payments
received on such loans are applied as a reduction of the loan principal
balance.  Interest income on other nonaccrual loans is recognized only to the
extent of interest payments received.

     The allowance for loan and lease losses is increased by provisions for
loan and lease losses which are included in the accompanying statements of
income. Losses are charged against the allowance for loan and lease losses
when management determines the collectibility of the principal is unlikely.
Recoveries on loans and leases previously charged off are credited to the
allowance.  Management's determination of the allowance is based on periodic
evaluations of the loan and lease portfolio which take into consideration
such factors as changes in the growth, size and composition of the loan and
lease portfolio, overall portfolio quality, prior loan and lease loss
experience, review of specific loans and leases, collateral, guarantees and
current economic conditions.

     DIRECT FINANCING LEASES - Income from direct financing leases is
recorded over the life of the lease under the financing method of accounting.
 The investment includes the sum of aggregate rentals receivable and the
estimated residual value of leased equipment less deferred income.

     PREMISES AND EQUIPMENT - Premises and equipment are stated at cost less
accumulated depreciation and amortization.  Depreciation is generally charged
to income over the estimated useful lives of the assets

                                     F-60

<PAGE>

by use of the straight-line method.  Leasehold improvements are amortized
over the terms of the leases or the estimated useful lives of improvements,
whichever is shorter.

     Estimated useful lives are as follows:

     Furniture, fixtures and equipment         3 to 10 years
     Leasehold improvements                    5 to 15 years

     OTHER REAL ESTATE OWNED - Real estate acquired through foreclosure or deed
in lieu of foreclosure is recorded at the lower of the outstanding loan balance
at the time of foreclosure or appraised value.  Gains and losses on the sale of
other real estate owned and write-downs resulting from periodic revaluation of
the property are charged to other operating expenses.

     ADVERTISING COSTS - The Company expenses the costs of advertising when
incurred.

     INCOME TAXES -  Deferred income taxes arise from temporary differences
between the tax basis of assets and liabilities and their reported amounts in
the financial statements.

     EARNINGS PER SHARE - Earnings per common share are based on the weighted
average number of common shares outstanding.  Earnings per common
share-assuming dilution are based on the weighted average number of common
and equivalent shares outstanding.  The average number of common shares
outstanding and common equivalent shares outstanding for the period ended
June 30, 1998 were 590,015 and 666,615, respectively.  The average number of
common shares outstanding and common equivalent shares outstanding for the
period ended June 30, 1997 were 575,665 and 663,966, respectively. Common
equivalent shares consist of the dilutive effect of stock options using the
treasury stock method.

     STATEMENT OF CASH FLOWS - For purposes of reporting cash flows, cash and
cash equivalents include cash on hand, amounts due from banks, and Federal
funds sold.  Generally, Federal funds are sold for one-day periods.

     In January of 1997, a dispute arose between the Bank as limited partner and
Affordable Communities, Inc., the general partner, over the amount of management
fees claimed to be owed to the general partner by the partnership.  In February
1997, the Bank initiated a lawsuit against the general partner because of this
dispute.  As of the date of this report, the Bank and the general partner have
negotiated a complete settlement of the dispute and a request for dismissal has
been filed with the court.  In connection with the settlement agreement, the
partnership is currently being dissolved and the Bank has received a $2,549,515
distribution in full satisfaction of its 50% interest in the partnership.

     The Company has a 50% limited partner interest in a another limited
partnership (Santa Paula Affordable Homes, Ltd.).  Affordable Communities, Inc.
is the general partner.  The partnership was originally formed to construct a
low-to-moderate income housing development in Santa Paula, California.  Due to
various factors, the development of the housing project will not commence.  As a
result, the partners are in the process of dissolving the Santa Paula Affordable
Homes, Ltd. partnership. The partnership's operations to date have not been
significant.  In connection with the partnership agreement, the Company had
purchased a parcel of land to sell to Santa Paula Affordable Homes, Ltd..  The
land was purchased in 1988 for $800,000. In December 1996, the Company wrote
down the land to estimated fair market value.  The write-down amounted to
$200,000 and was based upon an estimate of future discounted cash flows.  The
land was then sold to a 50% owner of Affordable Communities, Inc. for $600,000.
The Company financed 100% of the sale of the land.  In connection with the
aforementioned settlement agreement with Affordable Communities, Inc., this
partnership is also currently being dissolved.

     8. PROFIT SHARING AND DEFERRED COMPENSATION PLANS

     Profit Sharing - The Company has a profit sharing and salary deferral
401(k) plan for the benefit of its employees.  Under the plan, eligible
temployees may defer a portion of their salaries.  The Company may, at its
option, make matching contributions or profit sharing contributions. For the
periods ended June 30, 1998 and 1997, the Company matched 50% of the
employees' deferral which amounted to $44,246 and $7,960, respectively.  No
profit sharing contributions were made for the periods ended June 30, 1998
and 1997.

     Deferred Compensation, Directors and Chief Executive Officers -  In May 
1997, the Company approved the Directors' Retirement Plan and the Chief 
Executive Officer's Retirement Plan which restated and amended preexisting 
retirement plans.  The original plans provided for payments upon retirement, 
death or disability for the benefit of directors and the chief executive 
officer (now a director) of the Company.  The preexisting and the restated 
plans are nonqualified and nonfunded plans. The preexisting plans had been 
amended several times and as of January 1, 1997 provided for six years of 
retirement benefits upon retirement.  Under the restated plans,  each 
participant upon normal retirement, death, or disability will receive a 
monthly retirement benefit for 120 months in an amount stipulated in the 
agreement.  Any new participants shall vest 8% per year for services rendered 
after a three year waiting period has expired.  The plans also provide for 
reduced benefits upon early retirement.

     Deferred Compensation, Senior Officers - The Company has a nonqualified, 
nonfunded income continuation plan providing for payments upon retirement, 
death or disability of certain employees.  Under the plan, certain employees 
will receive retirement payments equal to a portion of the last three years' 
average compensation.  The payments are to be made monthly for a period of 
ten years. The plan also provides for reduced benefits upon early retirement, 
disability or termination of employment.

     As of December 31, 1997 and 1996, the projected benefit obligation and 
the net benefit liability of the plans are $1,698,863 and $1,599,281, 
respectively, and are included in other liabilities in the accompanying 
consolidated financial statements.  Compensation expense relating to the 
plans was $115,437 and $141,500 for the periods ended June 30, 1998 and 1997, 
respectively.

     In anticipation of the future obligation of the deferred compensation 
plans, the Company has invested in life insurance policies which are carried 
at cash surrender values of $2,254,886 and are included in other assets in 
the accompanying consolidated financial statements. The Company's intention 
is to partially fund these plans from the proceeds and investment earnings of 
the insurance policies and from the profits derived from the limited 
partnerships' operations (see Note 6).

     9. STOCK OPTION PLANS

     The Company has stock option plans which provide for the granting of 
options to directors and officers to purchase stock at its market value on 
the date the options are granted.  150,000 shares of common stock have been 
reserved for the granting of these options. Options granted become 
exercisable commencing from the date of a grant. For the participants who 
have been employed by or directors with the Company less than ten years, not 
more than 20% of the shares granted, plus shares left over from previous 
years, can be exercised in any one year. For participants who have been 
employed by or directors with the Company more than ten years, up to 100% can 
be exercised during the first year, with the


                                    F-67
<PAGE>

percentage decreasing by 20% increments over the next four years.  At the end 
of the fifth year, the options expire.

     In accordance with Statement of Financial Accounting Standards No. 123, 
"Accounting for Stock-Based Compensation" ("FAS 123"), which was effective as 
of January 1, 1996, the fair value of option grants is estimated on the date 
of grant using the Black-Scholes option-pricing model for pro forma footnote 
purposes. This information is not available as of June 30, 1998 and 1997. 
However, the weighted average fair value of annual option grants as of 
December 31, 1997 and 1996 was $2.56 and $2.62, respectively.

     As permitted by FAS 123, the Company has chosen to continue accounting 
for stock options at their intrinsic value.  Accordingly, no compensation 
expense has been recognized for its stock option compensation plans for the 
periods ended June 30, 1998 and 1997.

     10. SIGNIFICANT CONCENTRATIONS OF CREDIT RISK

<PAGE>

     Most of the Company's business activity is with customers throughout its 
primary market area of Ventura County, California.  The Company's loan 
portfolio is well diversified and no significant industry concentrations 
exist.

     Investments in state and municipal securities involve governmental 
entities within the State of California.  As of June 30, 1998, the Company 
had $20,228,503 due from a correspondent bank in excess of federal deposit 
insurance limits.

     11. POSTRETIREMENT BENEFIT PLANS OTHER THAN PENSIONS

     The Company provides health and life insurance benefits to retired 
employees and directors.  Employees may become eligible for benefits if they 
retire after attaining specified age and service requirements while they 
worked for the Company.  Directors may become eligible after five years 
regardless of their age at retirement.

     The Company implemented the provisions of Statement of Financial 
Accounting Standards No. 106, "Employers' Accounting for Postretirement 
Benefits Other Than Pensions" ("SFAS 106") effective January 1, 1996. These 
benefits are now accrued over the period the employee provides services to 
the Company.  Prior to the change, costs were charged to expense as incurred. 
The Company elected the delayed recognition treatment of the adoption of SFAS 
106.  Under this method, the transition obligation will be amortized on a 
straight line basis over the remaining service period of active plan 
participants.  The Company's current policy is to fund the cost of 
postretirement health care and life insurance plans on a pay-as-you-go basis.

     The net periodic cost for postretirement health care and life insurance 
benefits includes the following for the periods ended June 30:

     The assumed discount rate and the assumed rate of increase in 
compensation levels are 7.25% and 7.25%, respectively.  The assumed health 
care cost trend rate used in measuring the accumulated postretirement benefit 
obligation was 6% declining to 4.75% in 10 years. If the health care cost 
trend rate assumptions were increased by 1%, the accrued postretirement 
benefit cost, as of December 31, 1997, would be increased by approximately 
$22,732.

     12. REGULATORY MATTERS

     Capital requirements -  The Company is subject to various regulatory 
capital requirements administered by the Federal banking agencies.  The 
regulations require the Company to meet specific capital adequacy guidelines 
that involve quantitative measures of the Company's assets, liabilities, and 
certain off-balance-sheet items as calculated under regulatory accounting 
practices.  The Company's capital classification is also subject to 
qualitative judgements by the regulators about components, risk weighting, 
and other factors.  Failure to meet minimum capital requirements can initiate 
certain mandatory, and possibly additional discretionary, actions by 
regulators that, if undertaken, could have a direct material effect on the 
Company's financial statements.

     Quantitative measures established by regulation to ensure capital 
adequacy require the Company to maintain minimum amounts and ratios (set 
forth in the table below) of Tier 1 capital (as defined by the regulations) 
to total average assets (as defined), and minimum ratios of Tier 1 and total 
capital (as defined) to risk-weighted assets (as defined).  To be considered 
adequately capitalized (as defined) under the regulatory framework for prompt 
corrective action, the Company must maintain minimum Tier 1 leverage, Tier 1 
risk-based, total risk-based ratios as set forth in the table.  The Company's 
actual capital amounts and ratios are also presented in the table.

</TABLE>

     Rental expense was $257,575 and $197,783 for the periods ended June 30, 
1998 and 1997, respectively.

     At June 30, 1998, the Company had unused lines of credit with two banks. 
The lines total $4,700,000, have variable interest rates based on the lending 
bank's daily Federal funds rates, and are due on demand. The lines of credit 
are unsecured.

     14. FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

     The Company is a party to financial instruments with off-balance-sheet 
risk in the normal course of business to meet the financing needs of its 
customers. These financial instruments include commitments to extend credit 
and standby letters of credit.  These instruments involve, to varying 
degrees, elements of credit and interest rate risk in excess of the amount 
recognized in the statement of financial position.  Exposure to credit loss 
in the event of nonperformance by the other party to commitments to extend 
credit and standby letters of credit is represented by the contractual 
notional amount of those instruments.  At June 30, 1998, the Company had 
commitments to extend credit of $24,146,015 and obligations under standby 
letters of credit of $125,715.

     Commitments to extend credit are agreements to lend to a customer as 
long as there is no violation of any condition established in the contract. 
Commitments generally have fixed expiration dates or other termination 
clauses and may require payment of a fee.  Since many of the commitments are 
expected to expire without being drawn upon, the total commitment amounts do 
not necessarily represent future cash requirements.

     Standby letters of credit are conditional commitments issued by the 
Company to guarantee the performance of a customer to a third party. Those 
guarantees are primarily issued to support public and private borrowing 
arrangements, including commercial paper, bond financing, and similar 
transactions.

     The Company uses the same credit policies in making commitments and 
conditional commitments as it does for extending loan facilities to 
customers. The Company evaluates each customer's credit-worthiness on a 
case-by-case basis. The amount of collateral obtained, if deemed necessary 
upon extension


                                     F-71
<PAGE>

of credit, is based on management's credit evaluation of the counterparty. 
Collateral held varies but may include accounts receivable, inventory, 
property, plant, and equipment and real estate.

     15. FAIR VALUE OF FINANCIAL INSTRUMENTS

     Financial Accounting Standards No. 107 ("FAS 107"), "Disclosures About 
Fair Value of Financial Instruments" requires corporations to disclose the 
fair value of its financial instruments, whether or not recognized in the 
balance sheet, where it is practical to estimate that value.

     Fair value estimates made as of June 30, 1998 are based on relevant 
market information about the financial instruments.  These estimates do not 
reflect any premium or discount that could result from offering for sale at 
one time the Company's entire holding of a particular financial instrument. 
In cases where quoted market prices are not available, fair value estimates 
are based on judgements regarding future expected loss experience, current 
economic conditions, risk characteristics of various financial instruments, 
and other factors.

     These estimates are subjective in nature and involve uncertainties and 
matters of significant judgement and, therefore, cannot be determined with 
precision.  Changes in assumptions could significantly affect the estimates. 
In addition, the tax ramifications related to the realization of the 
unrealized gains and losses can have a significant effect on fair value 
estimates and have not been considered in the estimates.

     The following methods and assumptions were used by the Company in 
estimating its fair value disclosures for financial instruments:

     CASH AND CASH EQUIVALENTS - The carrying amounts reported in the balance 
sheets for cash and short-term instruments approximate those assets' fair 
values.

     SECURITIES - Fair values were based on quoted market prices, where 
available.  If quoted market prices were not available, fair values were 
based on quoted market prices of comparable instruments.

     LOANS - The carrying values, reduced by estimated inherent credit 
losses, of variable-rate loans and other loans with short-term 
characteristics were considered fair values.  For other loans, the fair 
market values were calculated by discounting scheduled future cash flows 
using current interest rates offered on loans with similar terms adjusted to 
reflect the estimated credit losses inherent in the portfolio.

     ACCRUED INTEREST RECEIVABLE AND ACCRUED INTEREST PAYABLE - The carrying 
amounts reported in the balance sheets for accrued interest receivable and 
accrued interest payable approximate their fair values.

     DEPOSIT LIABILITIES - The fair value of deposits with no stated 
maturity, such as noninterest-bearing demand deposits, NOW, savings, and 
money market deposits, was, by definition, equal to the amount payable on 
demand as of June 30, 1998.  The fair value of certificates of deposit was 
based on the discounted value of contractual cash flows, calculated using the 
discount rates that equaled the interest rates offered at the valuation date 
for deposits of similar remaining maturities.

     The following is a summary of the carrying amounts and estimated fair 
values of the Company's financial assets and liabilities at June 30, 1998:

     At June 30, 1998, the Bank had outstanding standby letters of credit and
commitments to extend credit.  These off-balance sheet financial instruments
are generally exercisable at the market rate prevailing at the date the
underlying transaction will be completed, and, therefore, they were deemed to
have no current fair market value (see Note 14).

     Fair value estimates are based on existing on- and off-balance sheet
financial instruments without attempting to estimate the value of anticipated
future business and the value of assets and liabilities that are not
considered financial instruments.  Significant assets and liabilities that
are not considered financial assets or liabilities include the discounted
value of fee revenues generated by the mortgage banking operation nor is the
value of deferred tax assets or premises and equipment considered.

         2.4   CERTAIN EXCEPTIONS AND LIMITATIONS. (A) Any shares of CIB 
Stock held by Americorp or any subsidiary of Americorp (other than shares 
held in a fiduciary capacity or as DPC Property) will be canceled at the 
Effective Time; (B) CIB Perfected Dissenting Shares shall not be converted 
into shares of Americorp Stock, but shall, after the Effective Time, be 
entitled only to such rights as are granted them by Chapter 13 of the CGCL 
(each dissenting shareholder who is entitled to payment for his shares of CIB 
Stock shall receive such payment in an amount as determined pursuant to 
Chapter 13 of CGCL), and (C) no fractional shares of Americorp Stock shall be 
issued in the Bank Merger and, in lieu thereof, each holder of CIB Stock who 
would otherwise be entitled to receive a fractional share shall receive an 
amount in cash equal to the product (calculated to the nearest ten 
thousandth) obtained by multiplying (a) the Americorp Book Value Per Share 
times (b) the fraction of the share of Americorp Stock to which such holder 
would otherwise be entitled.

         2.5   EXCHANGE PROCEDURES.

               (a)  As of the Effective Time, Americorp shall have deposited 
with the Exchange Agent for the benefit of the holders of shares of CIB 
Stock, for exchange in accordance with this Section 2.5 through the Exchange 
Agent, certificates representing the shares of Americorp Stock issuable 
pursuant to Section 2.3 in exchange for shares of CIB Stock outstanding 
immediately prior to the Effective Time, and funds in an amount not less than 
the amount of cash payable in lieu of fractional shares of Americorp Stock 
which would otherwise be payable in connection with Section 2.3 hereof, but 
for the operation of Section 2.4 of this Agreement (collectively, the 
"Exchange Fund").

              (b)  Americorp shall direct the Exchange Agent to mail promptly 
after the Effective Time, to each holder of record of a certificate or 
certificates which immediately prior to the Effective Time represented 
outstanding shares of CIB Stock (the "Certificates") whose shares were 
converted into the right to receive shares of Americorp Stock pursuant to 
Section 2.3 hereof:  (i) a letter of transmittal (which shall specify that 
delivery shall be effected, and risk of loss and title to the Certificates 
shall pass, only upon delivery of the Certificates to the Exchange Agent and 
shall be in such form and have such other provisions as CIB may reasonably 
specify), and (ii) instructions for use in effecting the surrender of the 
Certificates in exchange for certificates representing shares of Americorp 
Stock.  Upon surrendering of a Certificate for cancellation to the Exchange 
Agent or to such other agent or agents as may be appointed by CIB, together 
with such letters of transmittal, duly executed, the holder of such 
Certificate shall be entitled to receive in exchange therefor that amount of 
cash and a certificate representing that number of whole shares of Americorp 
Stock which such holder has the right to receive pursuant to the provisions 
of Sections 2.3 and 2.4 hereof, and the Certificate so surrendered shall 
forthwith be canceled.  In the event a Certificate is surrendered 
representing CIB Stock, the transfer of ownership which is not registered in 
the transfer records of CIB, a certificate representing the proper number of 
shares of Americorp Stock may be issued to a transferee if the Certificate 
representing such CIB Stock is presented to


                                       13

<PAGE>

the Exchange Agent, accompanied by all documents required to evidence and 
effect such transfer and by evidence that any applicable stock transfer taxes 
have been paid.  Until surrendered as contemplated by this Section 2.5 and 
except as provided in subsection (g) hereof, each Certificate shall be deemed 
at any time after the Effective Time to represent only the right to receive 
upon such surrender the certificate representing shares of Americorp Stock 
and cash in lieu of any fractional shares of stock as contemplated by this 
Section 2.5.  Notwithstanding anything to the contrary set forth herein, if 
any holder of shares of CIB should be unable to surrender the Certificates 
for such shares, because they have been lost or destroyed, such holder may 
deliver in lieu thereof, in the discretion of Americorp, such bond in form 
and substance and with surety reasonably satisfactory to Americorp and shall 
be entitled to receive the certificate representing the proper number of 
shares of Americorp Stock and cash in lieu of fractional shares in accordance 
with Sections 2.3 and 2.4 hereof.

              (c)  No dividends or other distributions declared or made after 
the Effective Time with respect to Americorp Stock with a record date after 
the Effective Time shall be paid to the holder of any unsurrendered 
Certificate with respect to the shares of Americorp Stock represented thereby 
and no cash payment in lieu of fractional shares shall be paid to any such 
holder pursuant to Section 2.4 until the holder of record of such Certificate 
shall surrender such Certificate.  Subject to the effect of applicable laws, 
following surrender of any such Certificate, there shall be paid to the 
record holder of the certificates representing whole shares of Americorp 
Stock issued in exchange thereof, without interest, (i) at the time of such 
surrender, the amount of any cash payable in lieu of a fractional share of 
Americorp Stock to which such holder is entitled pursuant to Section 2.4 and 
the amount of dividends or other distribution with a record date after the 
Effective Time theretofore paid with respect to such whole shares of 
Americorp Stock, and (ii) at the appropriate payment date, the amount of 
dividends or other distributions with a record date after the Effective Time 
but prior to surrender and a payment date subsequent to surrender payable 
with respect to such whole shares of Americorp Stock.

              (d)  All shares of Americorp Stock issued upon the surrender 
for exchange of CIB Stock in accordance with the terms hereof (including any 
cash paid pursuant to Section 2.4) shall be deemed to have been issued in 
full satisfaction of all rights pertaining to such shares of CIB Stock, and 
there shall be no further registration of transfers on the stock transfer 
books of the Surviving Bank of the shares of CIB Stock which were outstanding 
immediately prior to the Effective Time.  If after the Effective Time, 
Certificates are presented to Americorp for any reason, they shall be 
canceled and exchanged as provided in this Agreement.

              (e)  Any portion of the Exchange Fund which remains 
undistributed to the shareholders of CIB following the passage of six months 
after the Effective Time shall be delivered to Americorp, upon demand, and 
any shareholders of CIB who have not theretofore complied with this Section 
2.5 shall thereafter look only to Americorp for payment of their claim for 
Americorp Stock, any cash in lieu of fractional shares of Americorp Stock and 
any dividends or distributions with respect CIB Stock.


                                       14

<PAGE>

              (f)  Neither Americorp nor CIB shall be liable to any holder of 
shares of CIB Stock for such shares (or dividends or distributions with 
respect thereto) or cash from the Exchange Fund delivered to a public 
official pursuant to any applicable abandoned property, escheat or similar 
law.

              (g)  The Exchange Agent shall not be entitled to vote or 
exercise any rights of ownership with respect to the shares of Americorp 
Stock held by it from time to time hereunder, except that it shall receive 
and hold all dividends or other distributions paid or distributed with 
respect to such shares of Americorp Stock for the account of the Persons 
entitled thereto. Former shareholders of record of CIB shall be entitled to 
vote after the Effective Time at any meeting of Americorp shareholders the 
number of whole shares of Americorp Stock into which their respective shares 
of CIB Stock are converted, regardless of whether such holders have exchanged 
their Certificates for certificates representing Americorp Stock in 
accordance with the provisions of this Agreement.

         2.6   DIRECTORS' AGREEMENTS.

              (a)  Concurrently with the execution of this Agreement, 
Americorp and Bank shall cause each of its respective directors to enter into 
a Americorp Directors' Agreement.

              (b)  Concurrently with the execution of this Agreement, CIB 
shall cause each of its respective directors to enter into an CIB's 
Directors' Agreement.

jurisdiction other than in California where the failure to be so


                                       15

Americorp on a consolidated basis.

         3.2   CAPITALIZATION.  As of the date of this Agreement, the 
authorized capital stock of Americorp consists of 2,500,000 shares of

Letter, there are no outstanding options, warrants or other rights in or with 
respect to the unissued shares of Americorp Stock or Bank Stock or any other

obligated to issue any additional shares of its capital stock or any options, 
warrants or other rights in or with respect to the unissued shares of its 
capital stock or any other securities convertible into such stock.

         3.3   SUBSIDIARIES.  Except as set forth in Americorp's Disclosure 
Letter, neither Americorp nor Bank own, directly or indirectly, any

Bank has any liabilities, whether absolute, accrued, contingent or otherwise.

         3.5   AUTHORITY OF AMERICORP AND BANK.  The execution and delivery 
by Americorp and Bank of this Agreement and, subject to the requisite 
approval of the shareholders of Americorp and of Americorp as the sole 
shareholder of Bank, the consummation of the transactions contemplated hereby 
have been duly and validly authorized by all necessary corporate action on 
the part of Americorp and Bank, and this Agreement is a valid and binding 
obligation of Americorp and Bank enforceable in accordance with its terms, 
except as the enforceability thereof may be limited by bankruptcy,

                                       16

<PAGE>

similar laws affecting the rights of creditors generally and by general 
equitable principles and by Section 8(b)(6)(D) of the Federal Deposit

the transactions contemplated herein, nor compliance by Americorp and Bank 
with any of the provisions hereof, will: (a) violate any provision of their 
respective Charter Documents; (b) constitute a breach of or result in a 
default (or give rise to any rights of termination, cancellation or 
acceleration, or any right to acquire any securities or assets) under any of 
the terms, conditions or provisions of any note, bond, mortgage, indenture, 
franchise, license, permit, agreement, Encumbrances or other instrument or 
obligation to which Americorp or Bank is a party, or by which Americorp or 
Bank or any of their respective properties or assets is bound, if in any such 
circumstances, such event could have consequences materially adverse to 
Americorp on a consolidated basis; or (c) violate any Rule applicable to 
Americorp or Bank or any of their respective properties or assets.  No

bonds covering their assets and businesses against such casualties and 
contingencies and in such amounts, types and forms as are customary in the 
banking industry for  their businesses, operations, properties and assets.  
All such insurance policies and bonds are in full force and effect.  Except 
as set forth in Americorp's Disclosure Letter, neither Americorp nor Bank has 
received notice from any insurer that any such policy or bond has canceled or 
indicating an intention to cancel or not to renew any such policy or bond or 
generally disclaiming liability thereunder.  Except as set forth in 
Americorp's Disclosure Letter, neither Americorp nor Bank is in default under 
any such policy or bond and all material claims thereunder have been filed in 
a timely fashion. Americorp's Disclosure Letter sets forth a list of all

<PAGE>

annual lease payment of $10,000 or more, owned or leased by Americorp or 
Bank.  Americorp and Bank have good and marketable title to all their 
respective properties and assets, other than real property, owned or stated 
to be owned by Americorp and Bank, free and clear of all Encumbrances except: 
(a) as set forth in the Financial Statements of Americorp; (b) Encumbrances

are not substantial in character, amount or extent, (ii) do not materially 
detract from the value, (iii) do not interfere with present use, of the 
property subject thereto or affected thereby, and (iv) do not otherwise 
materially impair the conduct of business of Americorp and Bank; or (d) as 
set forth in Americorp's Disclosure Letter.

         3.8   REAL ESTATE.  Americorp's Disclosure Letter sets forth a list 
of all real property, including leaseholds, owned by Americorp and Bank, 
together with (i) a description of the locations thereof, (ii) a description

and marketable title to the respective real property, and valid leasehold

co-lessees or sublessees in such matters that are reflected in the lease; (b) 
Encumbrances for current taxes not yet due and payable; (c) Encumbrances 
incurred in the ordinary course of business, if any, that, to the knowledge 
of Americorp and Bank, (i) are not substantial in character, amount or 
extent, (ii) do not materially detract from the value, (iii) do not interfere 
with present use, of the property subject thereto or affected thereby, and 
(iv) do not otherwise materially impair the conduct of business of Americorp 
or Bank; or (d) as set forth in Americorp's Disclosure Letter.  Americorp or 
Bank, as the case may be, as lessee, has the right under valid and subsisting 
leases to occupy, use and possess all property leased by it, as identified in 
Americorp's Disclosure Letter, and, to the knowledge of Americorp and Bank, 
there has not occurred under any such lease any breach, violation or default. 
 Except as set forth in Americorp's Disclosure Letter and except with respect 
to deductibles under insurance policies set forth in Americorp's Disclosure 
Letter, neither Americorp nor Bank has experienced any uninsured damage or 
destruction with respect to the properties identified in Americorp's 
Disclosure Letter.  To the knowledge of Americorp and Bank, all properties 
and assets used by Americorp and Bank are in good operating condition and 
repair, suitable for the purposes for which they are currently utilized, and 
comply with all applicable Rules related thereto.  Americorp and Bank enjoy 
peaceful and undisturbed possession under all leases for the use of real or 
personal property under which it is the lessee, and, to the knowledge of 
Americorp and Bank, all leases to which Americorp or Bank is a party are 
valid and enforceable in all material respects in accordance with the terms 
thereof except as may be limited by bankruptcy, insolvency, moratorium or 
other similar laws affecting creditors' rights and except as may be limited 
by the exercise of judicial discretion in applying principles of equity.  
Neither Americorp nor Bank is in default with respect to any such lease, and 
to the knowledge of the officers of Americorp and Bank no event has occurred 
which with the lapse of time or the giving of notice, or both, would 
constitute a default


                                       18

<PAGE>

under any such lease.  Copies of each such lease are attached to Americorp's 
Disclosure Letter.

         3.9   LITIGATION.  Except as set forth in Americorp's Disclosure 
Letter, to the knowledge of Americorp and Bank, there is no private or 
governmental suit, claim, action, investigation or proceeding pending, nor to 
Americorp's or Bank's knowledge threatened, against Americorp or Bank or 
against any of their directors, officers or employees relating to the 
performance of their duties in such capacities or against or affecting any 
properties of Americorp or Bank.  Also, except as disclosed in Americorp's 
Disclosure Letter, there are no judgments, decrees, stipulations or orders 
against Americorp or Bank enjoining either of them or any of their directors, 
officers or employees in respect of, or the effect of which is to prohibit, 
any business practice or the acquisition of any property or the conduct of 
business in any area of Americorp or Bank.  To the knowledge of Americorp and 
Bank, neither Americorp nor Bank is a party to any pending or, to the 
knowledge of any of the officers, threatened legal, administrative or other 
claim, action, suit, investigation, arbitration or proceeding challenging the 
validity or propriety of any of the transactions contemplated by this

character required to be filed by it and have paid all taxes, together with 
any interest and penalties owing in connection therewith, shown on such 
returns to be due in respect of the periods covered by such returns, other

Letter, Americorp and Bank have filed all required payroll tax returns, have 
fulfilled all tax withholding obligations and have paid over to the 
appropriate governmental authorities the proper amounts with respect to the 
foregoing.  The tax and audit positions taken by Americorp and Bank in 
connection with the tax returns described in the preceding sentence were 
reasonable and asserted in good faith.  Adequate provision has been made in 
the books and records of Americorp or Bank and, to the extent required by 
generally accepted accounting procedures, reflected in the Financial 
Statements of Americorp, for all tax liabilities, including interest or 
penalties, whether or not due and payable and whether or not disputed, with 
respect to any and all federal, foreign, state, local and other taxes for the

Americorp's Disclosure Letter sets forth (i) the date or dates through which 
the IRS has examined the federal tax returns of Americorp and Bank and the 
date or dates through which any foreign, state, local or other taxing 
authority has examined any other tax returns of Americorp and Bank; (ii) a 
complete list of each year for which any federal, state, local or foreign tax 
authority has obtained or has requested an extension of the statute of 
limitations from Americorp or Bank and lists each tax case of Americorp or

litigation; and (iii) the date and issuing authority of each statutory notice 
of deficiency, notice of proposed assessment and revenue agent's report 
issued to Americorp within the last twelve (12) months.   Except as set forth 
in Americorp's Disclosure Letter, to the knowledge of Americorp and Bank,


                                       19

<PAGE>

neither the IRS nor any foreign, state, local or other taxing authority has, 
during the past three years, examined or is in the process of examining any 
federal, foreign, state, local or other tax returns of Americorp or Bank.  To 
the knowledge of Americorp and Bank, neither the IRS nor any foreign, state, 
local or other taxing authority is now asserting or threatening to assert any 
deficiency or claim for additional taxes (or interest thereon or penalties in 
connection therewith) except as set forth in Americorp's Disclosure Letter.

         3.11  COMPLIANCE WITH LAWS AND REGULATIONS. Except as set forth in 
Americorp's Disclosure Letter, neither Americorp nor Bank is in default under

              (c)  With respect to all CIB Benefit Arrangements, CIB is in 
substantial compliance (other than noncompliance the cost or liability for

period of its directors' and officers' liability insurance for a period of 36
months with respect to all matters arising from facts or events which occurred

                (b)  If Americorp or Bank or any of its successors or assigns
(i) shall consolidate with or merge into any other corporation or entity and
shall not be the continuing or surviving corporation or entity of such

                (c)  The provisions of this Section are intended to be for the
benefit of, and shall be enforceable by, each director or officer of CIB and his
or her heirs and representatives.

          5.13  NO SHOP.  Neither Americorp  nor any of its Affiliates shall, on
or before the earlier of the Effective Time or the date of termination of this
Agreement, initiate, solicit or encourage (including by way of furnishing
information or assistance), or take any other action to facilitate, any
inquiries or the making of any proposal which constitutes, or may reasonably be
expected to lead to any Competing Transaction (as such term is defined in
Section 6.13), or negotiate with any Person in furtherance of such inquiries or
to obtain a Competing Transaction, or agree to or endorse any Competing
Transaction, or authorize or permit any of its officers, directors or employees
or any investment banker, financial advisor, attorney, accountant or any other

in this Section 5.13 or elsewhere in this Agreement, the obligations of
Americorp  in this Agreement are subject to the continuing fiduciary duties of
its Board of Directors.  In the event the Board of Directors of Americorp
receives a bona fide offer for a Competing Transaction with another entity, and
reasonably determines, upon written advice of counsel, that as a result of such
offer, any duty to act or to refrain from doing any act pursuant to this
Agreement, is inconsistent with the continuing fiduciary duties of said Board of
Directors to their shareholders, such failure to act or refrain from doing any
act shall not constitute the failure of any condition, breach of any covenant or
otherwise constitute any breach of this Agreement, except that any such failure
to act or refrain from doing any act shall entitle CIB to terminate this
Agreement pursuant to Section 10.1(g) hereof,  and  in no event shall this
sentence or the previous sentence operate to excuse or modify the obligations of
Americorp  under Section 11.1(d) hereof.

          5.14  BANK BENEFIT ARRANGEMENTS.  Subject to Article 9 hereof, Bank
and any effected officers, directors or employees shall mutually terminate all

          6.13  NO SHOP.  Neither CIB nor any of its Affiliates shall, on or
before the earlier of the Effective Time or the date of termination of this
Agreement, initiate, solicit or encourage (including by way of furnishing
information or assistance), or take any other action to facilitate, any

expected to lead to any Competing Transaction (as such term is defined below),
or negotiate with any Person in furtherance of such inquiries or to obtain a
Competing Transaction, or agree to or endorse any Competing Transaction, or
authorize or permit any of its officers, directors or employees or any
investment banker, financial advisor, attorney, accountant or any other
representative retained by it or any of its Affiliates to take any such action,
and CIB shall promptly notify Americorp (orally and in writing) of all of the
relevant details relating to all inquiries and proposals which they may receive

shall mean any of the following involving CIB: any merger, consolidation,
share exchange or other business combination; a sale, lease, exchange,
mortgage, pledge, transfer or other disposition of assets of CIB representing
ten percent (10%) or more of the asset of CIB; a sale of shares of capital
stock (or securities convertible or exchangeable into or otherwise
evidencing, or any agreement or instrument evidencing, the right to acquire

obligations of CIB in this Agreement are subject to the continuing fiduciary
duties of its Board of Directors.  In the event the Board of Directors of CIB
receives a bona fide offer for a Competing Transaction with another entity,
and reasonably determines, upon written advice of counsel, that as a result
of such offer, any duty to act or to refrain from doing any act pursuant to
this Agreement, is inconsistent with the continuing fiduciary duties of said
Board of Directors to their shareholders, such failure to act or refrain from
doing any act shall not constitute the failure of any condition, breach of
any covenant or otherwise constitute any breach of this Agreement, except
that any such failure to act or refrain from doing any act shall entitle
Americorp to terminate this Agreement pursuant to Section 10.1(f) hereof,
and  in no event shall this sentence or the previous sentence operate to
excuse or modify the obligations of CIB under Section 11.1(c) hereof.

thirty (30) days of the execution of this Agreement, (a) CIB shall deliver to
Americorp a letter identifying all persons who are then "affiliates" of CIB for
purposes of Rule 145 under the Securities Act and (b) CIB shall advise the
persons identified in such letter of the resale restrictions imposed by
applicable securities laws and shall use reasonable efforts to obtain from each
person identified in such letter a written agreement substantially in the form
attached hereto as Exhibit 6.14.  CIB shall use reasonable efforts to obtain
from any person who becomes an affiliate of CIB after CIB's delivery of the
letter referred to above, and on or prior to the date of the CIB Shareholders'
Meeting to approve this Agreement, a written agreement substantially in the form
attached as Exhibit 6.14 hereto as soon as practicable after obtaining such
status.  At least 10 Business Days prior to the issuance of the opinion to be
provided for in Section 8.1(h), CIB shall use its best efforts to cause each
person or group of persons who holds more than five percent (5%) of the CIB
Stock (regardless of whether such person is an "affiliate" under Rule 145) to
deliver to F&K, VTD and Reitner & Stuart, a letter stating that such
shareholder(s) has no present plan or intention to dispose of CIB Stock and
committing that such shareholder(s) will not dispose of CIB Stock in a manner to
cause a violation of the "continuity of shareholder interest" requirements of
Treasury Regulation 1.368-1.

<PAGE>

                                                         July 7, 1998


     Members of the Board of Directors
     Channel Islands Bank
     1555 South "A" Street
     Oxnard, California 93030


     Members of the Board:

     You have requested our opinion as investment bankers as to the fairness, 
from a financial perspective, to the shareholders of Channel Islands Bank, 
Oxnard, California ("CIB") of the terms of the proposed merger of CIB with 
and into American Commercial Bank, Ventura, California ("ACB") and CIB 
shareholders receiving shares of common stock of ACB's parent corporation, 
Americorp, Ventura, California ("Americorp") as defined in the Agreement to 
Merge and Plan of Reorganization (the "Agreement") entered into as of July 7, 
1998.  Pursuant to the Agreement and subject to the terms and conditions 
therein, each share of CIB Stock issued and outstanding immediately prior to 
the Effective Time of the Merger shall, on and at the Effective Time of the 
Merger, pursuant to the Agreement and without any further action on the part 
of CIB or the holders of CIB Stock, be exchanged for and converted into the 
right to receive shares of Americorp Stock which is equal to the Exchange 
Ratio.  The Exchange Ratio is obtained by dividing the CIB Book Value Per 
Share by the Americorp Book Value Per Share.  The components of CIB Book 
Value Per Share and Americorp Book Value Per Share are set forth in the 
Agreement.

     As part of its investment banking business, The Findley Group is 
continually engaged in the valuation bank, bank holding company and thrift 
securities in connection with mergers and acquisitions nationwide.  We have 
not previously provided investment banking and financial advisory services to 
CIB.

     In arriving at our opinion, we have reviewed and analyzed, among other 
things, the following:  (i) a draft of the Agreement; (ii) Annual Reports to 
Shareholders of CIB and Americorp for the years ended December 31, 1997 and 
December 31, 1996; (iii) Quarterly Call Reports for the Quarters ended March 
31, 1998 , December 31, 1997,  September 30, 1997, June 30, 1997, March 31, 
1997 and December 31, 1996 for CIB and ACB; (iv) certain  other  publicly 
available financial  and  other  information  concerning CIB, Americorp and 
ACB; and (v) publicly available information concerning other banks and 
holding companies, the trading markets for their securities and the nature 
and terms of certain other merger transactions we believe relevant to our 
inquiry.  We have held discussions with senior management of CIB concerning 
their past and current operations, financial condition and prospects, as well 
as the results of regulatory examinations.

                                       B-1

<PAGE>

     We have reviewed earnings projections for 1998 through 2002 for CIB and 
ACB as stand-alone entities, assuming the Merger does not occur, prepared by 
the respective entities.  We reviewed earnings projections for 1998 through 
2002, assuming the Merger does occur, as well as projected operating cost 
savings and earnings enhancement opportunities expected to be achieved in 
each such years resulting from the Merger.  Certain pro forma financial 
projections for the combined entity were derived by us based partially upon 
the projections discussed above, as well as our own assessment of general 
economic, market and financial conditions.  In certain cases, such combined 
pro forma financial projections included projected operating cost savings and 
earnings enhancement opportunities derived by us partially based upon the 
projections discussed above to be realizable in the Merger.

     In conducting our review and in arriving at our opinion, we have relied
upon and assumed the accuracy and completeness of the financial and other
information provided to us or publicly available, and we have not assumed any
responsibility for independent verification of the same.  We have relied upon
the management of CIB and Americorp as to the reasonableness of the financial
and operating forecasts, projections and projected operating cost savings and
earnings enhancement opportunities (and the assumptions and bases therefor)
provided to us, and we have assumed that such forecasts, projections and
projected operating cost savings and earnings enhancement opportunities
reflect the best currently available estimates and judgements of the
applicable management's.  We have also assumed, without assuming any
responsibility for the independent verification of the same, that the
aggregate allowances for loan losses for CIB and ACB are adequate to cover
such losses.  We have not made or obtained any evaluations or appraisals of
the property of CIB or Americorp, nor have we examined any individual loan
credit files.  For purposes of this opinion, we have assumed that the Merger
will have the tax, accounting and legal effects described in the Agreement
and assumed the accuracy of the disclosures set forth in the Agreement.  Our
opinion as expressed herein is limited to the fairness, from a financial
perspective, to the holders of the shares of CIB Common Stock of the terms of
the proposed merger of CIB with and into ACB, with CIB shareholders receiving
shares of Americorp Stock and does not address CIB's underlying business
decision to proceed with the Merger.

     We have considered such financial and other factors as we have deemed
appropriate under the circumstances, including among others the following:
(i) the historical and current financial position and results of operations
of CIB and Americorp; (ii) the assets and liabilities of CIB and Americorp,
including the loan and investment portfolios, deposits, other liabilities,
historical and current liability sources and costs and liquidity; and (iii)
the nature and terms of certain other merger transactions involving banks and
bank holding companies.  We have also taken into account our assessment of
general economic, market and financial conditions and our experience in other
transactions, as well as our experience in securities valuation and our
knowledge of the banking industry generally.  Our opinion is necessarily
based upon conditions as they exist and can be evaluated on the date hereof.

     Based upon and subject to the foregoing, we are of the opinion as

Dear Sirs:

     You have requested our opinion as to the fairness from a financial point
of view to the shareholders of Americorp of the terms of the proposed merger
of American Commercial Bank ("ACB") with Channel Islands Bank of Oxnard
("CIB") pursuant to the Agreement to Merge and Plan of Reorganization dated
as of July 7, 1998.  According to the terms of the Agreement each outstanding
share of CIB stock issued and outstanding immediately prior to the Effective
Time of the Merger shall be converted into shares of Americorp and each
certificate that represented shares of CIB stock shall evidence ownership of
shares of Americorp in accordance with the Exchange Ratio.  The Exchange
Ratio is obtained by dividing the CIB Book Value per share by the Americorp
Book Value per share. Components of Book Value per share are set forth in the
Agreement.

     In connection with this opinion, we have:

     (i)  Reviewed a draft and final copy of the Agreement to Merge and Plan
of Re-Organization;

     (ii) Reviewed certain publicly available business and financial
information on all the banks of Ventura County;

     (iii)     Reviewed Call Reports to the banking regulators for ACB and
CIB for the periods ending December 31, 1995, December 31, 1996, December 31,
1997, and March 31, 1998.  We have also reviewed the Annual Reports to
Stockholders for each bank for the years 1995, 1996 and 1997;

     (iv) Reviewed information for each bank pertaining to classified or
criticized loans, premises, lease terms for office facilities, internal
financial reports, summaries of stock options, stock prices for the last four
quarters, and other data provided us by the senior management personnel of
each bank.  We reviewed a pro-forma analysis of both banks as provided by
ACB's President/CEO;

                                       C-1

<PAGE>

     (v)  Reviewed certain other banking companies that California Research
considered relevant and compared them to ACB and CIB.  We have analyzed the
financial terms of banks involved in comparable merger and consolidation
transactions.

     We have had discussions with senior management personnel at both CIB and
ACB regarding current operations and projections of future lending volume and
earnings.  We have also reviewed with senior managements of both banks
earnings projections for ACB and CIB as stand-alone entities and ACB's senior
management forecasts regarding projected operating cost savings expected to
be achieved each year over the next three years resulting from the merger.

     We reviewed earnings projections for 1998, 1999 and 2000, assuming the
merger does occur and the projected operating cost savings to be expected
from the merger are achieved.  We made a series of pro-forma projections
based on our forecasts of earning assuming various levels of operating cost
savings are achieved.

     In rendering our opinion, we have relied upon and assumed the accuracy,
completeness and fairness of all of the financial and other information that
was available to us from public sources and that was provided to us by ACB
and CIB, including information provided during discussions with their
respective managements.  We have assumed that the merger will be accounted
for as a pooling of interests under generally accepted accounting principles.
 We have also assumed that in the course of obtaining the necessary
regulatory approvals for the merger, no restrictions will be imposed that
will have a material adverse effect on the contemplated benefits of the
merger.

     We have not independently verified such information nor undertaken an
independent evaluation or appraisal of any of the assets or liabilities of
ACB or CIB or been furnished with any such evaluation or appraisal.  We have
assumed that the aggregate allowances for loan losses for CIB and ACB are
adequate to cover possible loss without independently verifying them.  We
have not examined any individual loan credit files.

     Our opinion as expressed herein is limited to the fairness from a
financial point of view to the shareholders of Americorp in going ahead with the
merger.

     We have considered such financial and other factors as we have deemed
appropriate under the circumstances, including the present operations of both
banks, their current and historical financial trends, positions and the
nature and terms of other bank merger transactions.  Our opinion is based
upon market, economic and other conditions as they exist and can be evaluated.

     This opinion is for the use and benefit of the Board of Directors of
Americorp and ACB.  Our opinion does not constitute a recommendation to any
stockholder as to how such stockholder should vote on the proposed merger or
any matter related thereto.  It is expected that this opinion will be
included as part of the applications submitted to the

                                       C-2

<PAGE>

regulatory agencies and provided to the shareholders as part of the proxy
materials in relation to approval of the Merger.

     Based upon and subject to the foregoing and based upon such other
matters as we deem relevant, it is our opinion as of this date that the terms
of the Agreement and the Exchange Ratio are fair from a financial point of
view to the shareholders of Americorp.

     We consent to the filing of this opinion as Appendix C to the
Registration Statement and to the description of this opinion in the Joint
Proxy Statement/Prospectus.

Very truly yours,

/s/     BARRY M. RUBENS

                                  CHAPTER 13
                               DISSENTERS' RIGHTS


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

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

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

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

     (2)  Which were outstanding on the date for the determination of
          shareholders entitled to vote on the reorganization and (A) were
          not voted in favor of reorganization and (A) were not voted in favor
          of the reorganization or, (B) if described in subparagraph (A) or
          (B) of paragraph (1) (without regard to the provisos in that
          paragraph), were voted against the reorganization, or which were
          held of record on the effective date of a


                                       D-1

<PAGE>

          short-form merger; provided, however, that subparagraph (A) rather
          than subparagraph (B) of this paragraph applies in any case where
          the approval required by Section 1201 is sought by written consent
          rather than at a meeting.

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

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

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

SECTION 1301.  DEMAND FOR PURCHASE.

     (a)  If, in the case of a reorganization, any shareholders of a
corporation have a right under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, to require the corporation
to purchase their shares of cash, such corporation shall mail to each such
shareholder a notice of the approval of the reorganization by its outstanding
shares (Section 152) within 10 days after the date of such approval,
accompanied by a copy of Sections 1300, 1302, 1303, 1304 and this section, a
statement of the price determined by the corporation to represent the fair
market value of the dissenting shares, and a brief description of the
procedure to be followed if the shareholder desires to exercise the
shareholder's rights under such sections. The statement of price constitutes
an offer by the corporation to purchase at the price stated any dissenting
shares as defined in subsection (b) of Section 1300, unless they lose their
status as dissenting shares under Section 1309.

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

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

                                       D-2

<PAGE>

SECTION 1302.  ENDORSEMENT OF SHARES.

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

SECTION 1303.  AGREED PRICE -- TIME FOR PAYMENT.

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

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

SECTION 1304.  DISSENTER'S ACTION TO ENFORCE PAYMENT.

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

     (b) Two or more dissenting shareholder may join as plaintiffs or be
joined as defendants in any such action and two or more such actions may be
consolidated.

     (c) On the trial of the action, the court shall determine the issues. If
the status of the shares as dissenting shares is in issue, the court shall
first determine that issue.

                                       D-3

<PAGE>

If the fair market value of the dissenting shares is in issue, the court shall
determine, or shall appoint one or more impartial appraisers to determine, the
fair market value of the shares.

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

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

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

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

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

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

SECTION 1306.  DISSENTING SHAREHOLDER'S STATUS AS CREDITOR.

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

SECTION 1307.  DIVIDENDS PAID AS CREDIT AGAINST PAYMENT.


                                       D-4

<PAGE>

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

SECTION 1308.  CONTINUING RIGHTS AND PRIVILEGES OF DISSENTING SHAREHOLDERS.

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

SECTION 1309.  TERMINATION OF DISSENTING SHAREHOLDER STATUS.

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

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

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

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

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

<PAGE>

SECTION 1310.  SUSPENSION OF PROCEEDINGS FOR PAYMENT OF PENDING LITIGATION.

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

SECTION 1311.  EXEMPT SHARES.

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

SECTION 1312.  ATTACKING VALIDITY OF REORGANIZATION OR MERGER.

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

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

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

     (x)  "Share" shall mean one share of Common Stock.

     3.   TERM OF THE PLAN AND AWARDS.

     (a)  Term of the Plan.  The Plan shall continue in effect for a term of
10 years from the Effective Date or the date the Plan is adopted by the Board
(whichever period ends earlier), unless sooner terminated pursuant to
Paragraph 15 hereof.  No Award shall be granted under the Plan after such 10
year term.

     (b)  Term of Awards.  The term of each Award granted under the Plan
shall be established by the Committee, but shall not exceed 10 years;
provided, however, that in the case of an Employee who owns Shares
representing more than 10% of the outstanding Common Stock at the time an ISO
is granted, the term of such ISO shall not exceed five years, subject to the
provisions of Section 8(e) hereof.

     4.   SHARES SUBJECT TO THE PLAN.
   
     Except as otherwise required by the provisions of Paragraph 10 hereof,
the aggregate number of Shares deliverable pursuant to Awards shall not
exceed 110,000 Shares.  Such Shares will be authorized but unissued Shares.
 If any Awards should expire, become unexercisable, or be forfeited, for any
reason without having been exercised or become vested in full, the Optioned
Shares shall, unless the Plan shall have been terminated, be available for
the grant of additional Awards under the Plan.
    
     5.   ADMINISTRATION OF THE PLAN.

     (a)  Composition of the Committee.  The Plan shall be administered by
the Committee, which shall consist of not less than three (3) members of the
Board who are Non-Employee Directors.  Members of the Committee shall serve
at the pleasure of the Board.  In the absence at any time of a duly appointed
Committee, the Plan shall be administered by those members of the Board who
are Non-Employee Directors.

     (b)  Powers of the Committee.  Except as limited by the express
provisions of the Plan or by resolutions adopted by the Board, the Committee
shall have sole and complete authority and discretion (i) to select
Participants and grant Awards, (ii) to determine the form and content of
Awards to be issued in the form of Agreements under the Plan, (iii) to
interpret the Plan, (iv) to prescribe, amend and rescind rules and
regulations relating to the Plan, (v) to make other determinations necessary
or advisable for the administration of the Plan.  The Committee shall have
and may exercise such other power and authority as may be delegated to it by
the Board from time to time.  A majority of the entire Committee shall
constitute a quorum and the action of a majority of the members present at
any meeting at which a quorum is present, or acts approved in writing by a
majority of the Committee without a meeting, shall be deemed the


                                      E-3
<PAGE>

action of the Committee.

     (c)  Agreement.  Each Award shall be evidenced by a written agreement
containing such provisions as may be approved by the Committee.  Each such
Agreement shall constitute a binding contract between the Company and the
Participant, and every Participant, upon acceptance of such Agreement, shall
be bound by the terms and restrictions of the Plan and of such Agreement.
The terms of each such Agreement shall be in accordance with the Plan.  In
particular, the Committee shall set forth in each Agreement (i) the Exercise
Price of an Option, (ii) the number of Shares subject to, and the expiration
date of, the Award, (iv) the restrictions, if any, to be placed upon such
Award, or upon Shares which may be issued upon exercise of such Award, and
(v) whether the Option is intended to be an ISO or a Non-ISO.

     The Chairman of the Committee and such other Directors and officers as
shall be designated by the Committee are hereby authorized to execute
Agreements on behalf of the Company and to cause them to be delivered to the
recipients of Awards.

     (d)  Effect of the Committee=s Decisions.  All decisions, determinations
and interpretations of the Committee shall be final and conclusive on all
persons affected thereby.

     (e)  Indemnification.  In addition to such other rights of
indemnification as they may have, the members of the Committee shall be
indemnified by the Company in connection with any claim, action, suit or
proceeding relating to any action taken or failure to act under or in
connection with the Plan or any Award, granted hereunder to the full extent
provided for under the Company=s governing instruments with respect to the
indemnification of Directors.

     6.   GRANT OF OPTIONS.
   
     (a)  General Rule.  Only key Employees and Directors and Consultants shall 
be eligible to receive grants of Options pursuant to the Plan.
    
     (b)  Special Rules for ISOs.  The aggregate Market Value, as of the date
the option is granted, of the Shares with respect to which ISOs are
exercisable for the first time by an Employee during any calendar year (under
all incentive stock option plans, as defined in Section 422 of the Code, of
the Company or any present or future Parent or Subsidiary of the Company)
shall not exceed $100,000.  Notwithstanding the foregoing, the Committee may
grant Options in excess of the foregoing limitations, in which case such
Options granted in excess of such limitations shall be Options which are
Non-ISOs.

   
     (c)  Delivery of Information.   The Company shall deliver to each Optionee
at the times required, the information and financial statements provided for
in Rule 428 (b) of the Securities and Exchange Commission's Regulation C and by
Section 260.140.46 of the Rules of the California Corporations Commissioner.
    

     7.   EXERCISE PRICE FOR OPTIONS

     (a)  Limits on Committee Discretion.  The Exercise Price as to any
particular Option  shall not be less than 100% of the Market Value of the
Options Shares on the date of grant

                                      E-4
<PAGE>

without taking into account any restrictions on the Optioned Shares.  In the
case of an Employee who owns Shares representing more than 10% of the
Company's outstanding Shares of Common Stock at the time an ISO is granted,
the Exercise Price shall not be less than 110% of the Market Value of the
Optioned Shares at the time the ISO is granted.

     (b)  Standards for Determining Exercise Price.  If the Common Stock is
listed on a national securities exchange (including NASDAQ National Market or
Small Cap System) on the date in question, then the Market Value per Share
will be the average of the highest and lowest selling price on such exchange
on such date, or if there were no sales on such date, then the Exercise Price
 shall be the mean between the bid and asked price on such date.  If the
Common Stock is traded otherwise than on a national securities exchange on
the date in question, then the Market Value per Share shall be the mean
between the bid and asked price on such date, or, if there is no bid and
asked price on such date, then on the next prior business day on which there
was a bid and asked price.  If no such bid and asked price is available, then
the Market Value per Share shall be its fair market value as determined by
the Committee, in its sole and absolute discretion.

     8.   EXERCISE OF OPTIONS.

     (a)  Generally.  Subject to (e) below, any Option granted hereunder
shall be exercisable at such times and under such conditions as shall be
permissible under the terms of the Plan and of the Agreement granted to a
Participant.  An Option may not be exercised for a fractional Share.

     (b)  Procedure for Exercise.  A Participant may exercise Options,
subject to provisions relative to its termination and limitations on its
exercise, only by (1) written notice of intent to exercise the Option with
respect to a specified number of Shares, and (2) payment to the Company
(contemporaneously with delivery of such notice) in cash , in Common Stock,
or a combination of cash and Common Stock, of the amount of the Exercise
Price for the number of Shares with respect to which the Option is then being
exercised.  Each such notice shall be delivered, or mailed by prepaid
registered or certified mail, addressed to the Chief Financial Officer of the
Company at the Company's executive offices. Common Stock utilized in full or
partial payment of the Exercise Price for Options shall be valued at its
Market Value per Share at the date of exercise.

     (c)  Period of Exercisability.  Except to the extent otherwise provided
in more restrictive terms of an Agreement, an Option may be exercised by a
Participant only with respect to the vested portion of such Option and only
while he is an Employee or Director and has maintained Continuous Service
from the date of the grant of the Option, or within three months after
termination of such Continuous Service (but not later than the date on which
the Option would otherwise expire), except if the Employee's or Director's
Continuous Service terminates by reason of:

                                     E-5
<PAGE>
   
          (1)  "Just Cause" which for purposes hereof shall mean termination
     because of the Employee's or Director's personal dishonesty (meaning 
     material dishonesty with respect to any aspect of the Company's, the Bank's
     or an Affiliate's affairs or business), incompetence (which actually 
     results in substantial harm to the Company, the Bank or an Affiliate or 
     which could reasonably be expected to result in such harm), willful 
     misconduct, breach of fiduciary duty involving personal profit, 
     intentional failure to perform stated duties, willful violation of any law,
     rule or regulation (other than traffic violations or similar offenses) or
     final cease-and-desist order, then the Participant's rights to exercise
     such Option shall expire on the date of such termination;
    

          (2)  Death, then all Options of the deceased Participant shall become
     immediately exercisable and may be exercised within one year from the date
     of his death (but not later than the date on which the Option would
     otherwise expire) by the personal representatives of his estate or person
     or persons to whom his rights under such Option shall have passed by will
     or by laws of descent and distribution;

          (3)  Permanent and Total Disability (as such term is defined in
     Section 22(e)(3) of the Code), then all Options of the disabled Participant
     shall become immediately exercisable and may be exercised within one year
     from the date of such Permanent and Total Disability, but not later than
     the date on which the Option would otherwise expire.

     (d)  Effect of the Committee's Decisions.  The Committee's determination
whether a Participant's Continuous Service has ceased, and the effective date
thereof, shall be final and conclusive on all persons affected thereby.

   
     (e)  The vesting period of an Option shall be provided for in the 
Agreement and shall be determined in the sole discretion of the Committee; 
provided , however, that a minimum or 20% of the Option shall be exercisable 
in each year over a five year period from the date the Option is granted. The 
vesting periods for Options need not be identical.   Vesting shall cease 
immediately upon the termination of employment or directorship of an 
optionee.  If an optionee shall not in any given period exercise any of an 
Option which has become exercisable during that period, the optionee's right 
to exercise such part of the Option shall continue until expiration of the 
Option.
    

     9.   SUBSTITUTE OPTIONS.

     Notwithstanding any other provisions of this Plan to the contrary, where
the outstanding shares of another corporation are changed into or exchanged
for shares of Common Stock of the Company in a merger, consolidation,
reorganization or similar transaction, then, subject to the approval of the
Board, Options may be granted in exchange for unexercised, unexpired stock
options of the other corporation (whether to directors, officers or employees
and irrespective of whether they will continue with the Company), and the
exercise price of the Optioned Shares subject to such Option so granted may
be fixed at a price less than one hundred percent of the Market Value of the
Common Stock at the time such Option is granted if said Exercise Price has
been computed to be not less than the Exercise Price set forth in the stock
option of the other corporation, with appropriate adjustment to reflect the
exchange ratio of the shares of stock of the other corporation into the
shares of Common Stock of the Company.  The number of shares of the options
of the other corporation shall also be adjusted in accordance with the
exchange ratio so that any

                                     E-6
<PAGE>

substituted Option shall reflect such adjustment.

     10.  EFFECT OF CHANGES IN COMMON STOCK SUBJECT TO THE PLAN.

     (a)  Recapitalizations; Stock Splits, Etc.  The number and kind of
shares reserved for issuance under the Plan, and the number and kind of
shares subject to outstanding Awards (and the Exercise Price thereof), shall
be proportionately adjusted for any increase, decrease, change or exchange of
Shares for a different number or kind of shares or other securities of the
Company which results from a merger, consolidation, recapitalization,
reorganization, reclassification, stock dividend, split-up, combination of
shares, or similar event in which the number or kind of shares is changed
without the receipt or payment of consideration by the Company.

     (b)  Transactions in which the Company Is Not the Surviving Entity.  In
the event of (i) the liquidation or dissolution of the Company, (ii) a merger
or consolidation in which the Company is not the surviving entity,  (iii) the
sale or disposition of all or substantially all of the Company's assets or
(iv) a tender offer or acquisition by one person or a group of persons acting
in concert of more than 50% of the Company's outstanding Shares  (any of the
foregoing to be referred to herein as a "Transaction"), the Committee shall
notify each optionee of the pendency of the Transaction.  Upon delivery of
said notice, any Award granted prior to the Transaction shall be,
notwithstanding the provisions of Paragraph 8(e), exercisable in full and not
only as to those Shares with respect to which installments, if any, have been
accrued, subject, however, to earlier expiration or termination as provided
elsewhere in the Plan. Upon the date thirty (30) days after delivery of such
notice, any option or portion thereof not exercised shall terminate, and upon
the effective date of the Transaction, this Plan shall terminate, unless
provision is made in connection with the Transaction for assumption of
Options theretofore granted, or payment therefor, or substitution for such
Options of new options covering stock of a successor corporation, or a parent
or subsidiary corporation thereof, solely at the option of such successor
corporation or parent or subsidiary corporation, with appropriate adjustments
as to number and kind of shares and prices.

     (c)  Special Rule for ISOs.  Any adjustment made pursuant to
subparagraphs (a) or (b) hereof shall be made in such a manner as not to
constitute a modification, within the meaning of Section 424(h) of the Code,
of outstanding ISOs.

     (d)  Conditions and Restrictions on New, Additional or Difference Shares
or Securities.  If, by reason of any adjustment made pursuant to this
Paragraph, a Participant becomes entitled to new, additional or different
shares of stock or securities, such new, additional or different shares of
stock or securities shall thereupon be subject to all of the conditions and
restrictions which were applicable to the Shares pursuant to the Award before
the adjustment was made.

     (e)  Other Issuances.  Except as expressly provided in this Paragraph, the
issuance by

                                      E-7
<PAGE>

the Company or an Affiliate of shares of stock of any class, or of securities
convertible in to Shares or stock of another class, for cash or property or
for labor or services either upon direct sale or upon the exercise of rights
or warrants to subscribe therefor, shall not affect and no adjustment shall
be made with respect to, the number, class, Exercise Price of Shares then
subject to Awards or reserved for issuance under the Plan.

     11.  NON-TRANSFERABILITY OF AWARDS.

     Awards may not be sold, pledged, assigned, hypothecated, transferred or
disposed of in any manner other than by will or by the laws of descent and
distribution, or pursuant to the terms of a "qualified domestic relations
order" (within the meaning of Section 414(p) of the Code and the regulations
and rulings thereunder).  An Award may be exercised only by a Participant,
the Participant's personal representative or a permitted transferee.

     12.  TIME OF GRANTING AWARDS.

     The date of grant of an Award shall, for all purposes, be the later of
the date on which the Committee makes the determination of granting such
Award, and the Effective Date.   Notice of the determination shall be given
to each Participant to whom an Award is so granted within a reasonable time
after the date of such grant.

     13.  EFFECTIVE DATE.

     The Plan shall become effective immediately upon its approval by a
favorable vote of stockholders owning at least a majority of the Shares
eligible to be cast at a meeting duly held in accordance with applicable laws.

     14.  MODIFICATION OF AWARDS.

     At any time, and from time to time, the Board may authorize the
Committee to direct execution of an instrument providing for the modification
of any outstanding Award, provided no such modification shall confer on the
holder of said Award any right or benefit which could not be conferred on him
by the grant of a new Award at such time, or impair the Award without the
consent of the holder of the Award.

     15.  AMENDMENT AND TERMINATION OF THE PLAN.

     The Board may from time to time amend the terms of the Plan and, with
respect to any Shares at the time not subject to Awards, suspend or terminate
the Plan.

     Except for any changes that may be required to be made at the direction
of the Department of Corporations in connection with a permit procedure under
the California

                                    E-8
<PAGE>

Corporate Securities Law, shareholder approval must be obtained for any
amendment of the Plan that would change the number of Shares subject to the
Plan (except in accordance with Paragraph 10 above), change the category of
persons eligible to be Participants, or materially increase the benefits
under the Plan.

     No amendment, suspension or termination of the Plan shall, without the
consent of any affected holders of an Award, alter or impair any rights or
obligations under any Award theretofore granted.

     16.  CONDITIONS UPON ISSUANCE OF SHARES.

     (a)  Compliance with Securities Laws.  Shares of Common Stock shall not be
issued with respect to any Award unless the issuance and delivery of such Shares
shall comply with all relevant provisions of law, including, without limitation,
the Securities Act of 1933, as amended, the rules and regulations promulgated
thereunder, any applicable state securities law, and the requirements of any
stock exchange upon which the Shares may then be listed.

     (b)  Special Circumstance.  The inability of the Company to obtain
approval from any regulatory body or authority deemed by the Company's
counsel to be necessary to the lawful issuance and sale of any Shares
hereunder shall relieve the Company of any liability in respect of the
non-issuance or sale of such Shares.

     (c)  Committee Discretion.  The Committee shall have the discretionary
authority to impose in Agreements such restrictions on Shares as it may deem
appropriate or desirable.

     17.  RESERVATION OF SHARES.

     The Company, during the term of the Plan, will reserve and keep
available a number of Shares sufficient to satisfy the requirements of the
Plan.

     18.  WITHHOLDING TAX.

     The Company's obligation to deliver Shares upon exercise of Options
shall be subject to the Participant's satisfaction of all applicable federal,
state and local income and employment tax withholding obligations.  The
Committee, in its discretion, may permit the Participant to satisfy the
obligation, in whole or in part, by irrevocably electing to have the Company
withhold Shares, or to deliver to the Company Shares that he already owns,
having a value equal to the amount required to be withheld.  The value of
Shares to be with withheld, or delivered to the Company, shall be based on
the Market Value of the Shares on the date the amount of tax to be withheld
is to be determined.  As an alternative, the Company may retain, or sell
without notice, a number of such Shares sufficient to cover the amount
required to be withheld.


                                    E-9

<PAGE>


     19.  NO EMPLOYMENT OR OTHER RIGHTS.

     In no event shall an Employee's or Director's eligibility to participate
or participation in the Plan create or be deemed to create any legal or
equitable right of the Employee, Director, or any other party to continue
service with the Company, the Bank, or any Affiliate of such corporations.

     20.  GOVERNING LAW.

     The Plan shall be governed by and construed in accordance with the laws
of the State of California, except to the extent that federal law shall be
deemed to apply.

PART II   INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         CALIFORNIA LEGISLATION

     Americorp and its subsidiary, ACB, are subject to the California General 
Corporation Law (the "CGCL"), which provides a detailed statutory framework 
covering indemnification of any officer or other agent of a corporation who 
is made or threatened to be made a party to any legal proceeding by reason of 
his or her services on behalf of such corporation.

     With respect to indemnification, the CGCL provides that to the extent 
any officer, director or other agent of a corporation is successful "on the 
merits" in defense of any legal proceeding to which such person is a party or 
is threatened to be made a party by reason of his or her service on behalf of 
such corporation or in defense of any claim, issue, or matter therein, such 
agent shall be indemnified against expenses actually and reasonably incurred 
by the agent in connection therewith, but does not require indemnification in 
any other circumstance. The CGCL also provides that a corporation may 
indemnify any agent of the corporation, including officers and directors, 
against expenses, judgments, fines, settlements and other amounts actually 
and reasonably incurred in a third party proceeding against such person by 
reason of his or her services on behalf of the corporation, provided the 
person acted in good faith and in a manner he or she reasonably believed to 
be in the best interests of such corporation. The CGCL further provides that 
in derivative suites a corporation may indemnify such a person against 
expenses incurred in such a proceeding, provided such person acted in good 
faith and in a manner he or she reasonably believed to be in the best 
interests of the corporation and its shareholders. Indemnification is not 
available in derivative actions (i) for amounts paid or expenses incurred in 
connection with a matter that is settled or otherwise disposed of without 
court approval or (ii) with respect to matters for which the agent shall have 
been adjudged to be liable to the corporation unless the court shall 
determine that such person is entitled to indemnification.

     The CGCL permits the advancing of expenses incurred in defending any 
proceeding against a corporate agent by reason of his or her service on 
behalf of the corporation upon the giving of a promise to repay any such sums 
in the event it is later determined that such person is not entitled to be 
indemnified. Finally, the CGCL provides that the indemnification provided by 
the statute is not exclusive of other rights to which those seeking 
indemnification may be entitled, by bylaw, agreement or otherwise, to the 
extent additional rights are authorized in a corporation's articles of 
incorporation. The law further permits a corporation to procure insurance on 
behalf of its directors, officers and agents against any liability incurred 
by any such individual, even if a corporation would not otherwise have the 
power under applicable law to indemnify the director, officer or agent for 
such expenses.

     The Bylaws of Americorp and ACB contain provisions substantial identical 
to the provisions of the CGCL.

ITEM 22. UNDERTAKINGS.

     1. The undersigned registrant hereby undertake to file, during any 
period in which offers or sales are being made, a post-effective amendment to 
this registration statement:

        (i)  To include any prospectus required by section
        10(a)(3) of the Securities Act of 1933;

        (ii) To reflect in the prospectus any facts or events arising
        after the effective date of the registration statement (or the
        most recent post-effective amendment thereof) which,
        individually or in the aggregate, represent a fundamental
        change in the information set forth


                                      II-3
<PAGE>


        in the registration statement;

        (iii) To include any material information with respect to the
        plan of distribution not previously disclosed in the registration
        statement or any material change to such information in the
        registration statement;

PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section
do not apply if the registration statement is on Form S-3, Form S-8 or Form
F-3, and the information required to be included in a post-effective
amendment by those paragraphs is contained in periodic reports filed with or
furnished to the Commission by the registrant pursuant to section 13 or
section 15(d) of the Securities Exchange Act of 1934 that are incorporated by
reference in the registration statement.

     2. Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and
controlling persons of the registrant pursuant to the foregoing provisions,
or otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer
or controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against
public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

     3. The undersigned registrant hereby undertakes to supply by means
of a post-effective amendment all information concerning a transaction, and
the company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.

Channel Islands Bank
155 South A Street
Oxnard, CA 93032-0829

Gentlemen:

You have requested our opinion regarding certain federal income tax consequences
of the proposed merger of Channel Islands Bank ("Target") with and into American
Commercial Bank ("Sub").

                                      FACTS

Americorp, a corporation organized in California ("Parent"), is the parent
corporation of American Commercial Bank ("Sub"), also a California corporation
through which Parent engages in the business of general commercial banking.
Parent does not directly engage in the business of general commercial banking
but instead does so indirectly as the holding company for Sub.  Neither Parent
nor any person related to Parent owns, or immediately prior to the merger will
own, any stock of Target.

Target is a California corporation.  Target engages in the business of general
commercial banking.

The terms of the proposed merger (the "Merger") are contained in the Agreement
to Merge and Plan of Reorganization dated as of July 7, 1998 and amended on
September 17,1998 (the "Merger Agreement").

Terms not otherwise defined in this letter shall have the meanings assigned to
them in the Merger Agreement.

You have directed us to assume in preparing this opinion that (1) the Merger
will be consummated in accordance with the terms, conditions and other
provisions of the Merger Agreement, and (2) all of the factual information,
descriptions, representations and assumptions set forth in this letter, in the
Merger Agreement, in the letters to us from Parent dated September 1, 1998, and
from Target dated September 1, 1998 (the "Letters"), and in the Proxy
Statement/Prospectus dated _____, 1998, and mailed to Target shareholders in
connection with the special meeting of shareholders to approve the Merger, are
accurate and complete and will be accurate and complete at the time the Merger
becomes effective (the "Effective Date").  We have not independently verified
any factual matters relating to the Merger with or apart from our preparation of
this opinion and, accordingly, our opinion does not take into account any
matters not set forth herein which might have been disclosed by independent
verification.

Channel Islands Bank

The Merger Agreement provides that Target will in accordance with the Exchange
Ratio set forth in the Merger Agreement be merged with and into Sub in
accordance with the applicable provisions of the General Corporation Law of the
State of California and the California Financial Code.  The Merger must be
approved as required by law by the Target shareholders at a special meeting to
be held on _____, 1998.

On the Effective Date, all assets and liabilities of Target will be transferred
by operation of law to Sub; the separate corporate existence of Target will
cease, and, except as provided below, each share of Target Common Stock then
outstanding will be converted into .7000 share of Parent Common Stock.  In the
event Parent changes (or establishes a record date for changing) the number of
shares of Parent Common Stock issued and outstanding prior to the Effective Date
as a result of a stock split, stock dividend, recapitalization or similar
transaction with respect to the outstanding Parent Common Stock and the record
date therefor shall be prior to the Effective Date, the Exchange Ratio shall be
proportionately adjusted.

No fractional shares of Parent Common Stock will be issued in the Merger.  Each
holder of Target Common Stock, who otherwise would be entitled to receive a
fraction of a share of Parent Common Stock, will receive instead, cash equal to
such fraction multiplied by the Parent's book value per share.  Except for cash
paid to dissenters and cash exchanged in lieu of issuing fractional shares of
Parent Common Stock, no cash will be exchanged for shares of Target Common Stock
or shares of Parent Common Stock pursuant to the Merger.

On the Effective Date, Target's obligations with respect to stock options, shall
be assumed by Parent for (i) each and every officer and employee of Target who
shall continue as an officer and employee of Sub and (ii) each director of
Target.  Each outstanding option, shall become the right to receive, upon
payment of the exercise price, that number of shares of Parent Common Stock
equal to the product of the Exchange Ratio and the number of shares of Target
Common Stock covered by the option.

Except for the options issued pursuant to above, no options to purchase Target
Common Stock and no securities or other instruments convertible into Target
Common Stock will be outstanding on the Effective Date.

We have also relied with your permission on the following additional
representations and/or assumptions:

     1.   The Merger will be a statutory merger in accordance with the
          applicable provisions of the General Corporation Law of the State of
          California and the California Financial Code.

     2.   The fair market value of the Parent Common Stock and other
          consideration received by each Target shareholder will be
          approximately equal to the fair market value of the Target Common
          Stock surrendered in the exchange.

     3.   Target has not (and, as of the Effective Date, will not have)
          redeemed, and no person related (within the meaning of Treasury
          Regulation Section 1.368-1(e)(3)) to Target has (or, as of the
          Effective Date, will have) acquired, any stock of Target (1) within
          one year prior to the Effective Date, or, (2) as part of a plan which
          includes the Merger.

     4.   Parent has no plan or intention to reacquire, and no person related
          (within the meaning of Treasury Regulation Section 1.368-1(e)(3)) to
          Parent has any intention to acquire, any of the Parent Common Stock to
          be issued in the Merger.

     5.   Except as provided in the next sentence, Parent, Target and the
          shareholders of Target will pay their respective expenses, if any,
          incurred in connection with the Merger.  Sub will pay or assume only
          those expenses of Target that are solely and directly related to the
          Merger in accordance with the guidelines established in Rev. Rul.
          73-54, 1973-1 C.B. 187.

     6.   There is no intercorporate indebtedness existing between Sub and
          Target that was issued, acquired or will be settled at a discount.

     7.   No two parties to the Merger are investment companies as defined in
          section 368(a)(2)(F)(iii) and (iv).

     8.   Target is not under the jurisdiction of a court in a title 11 or
          similar case within the meaning of section 368(a)(3)(A).

     9.   The fair market value of the assets of Target transferred to Sub will
          equal or exceed the sum of the liabilities assumed by Sub plus the
          amount of liabilities, if any, to which the transferred assets are
          subject.

     10.  Except as described in the Proxy Statement/Prospectus, no dividends or
          distributions, other than regular or normal dividends or
          distributions, will be made with respect to any Target stock prior to
          the Merger.  After the Merger, no dividends or distributions will be
          made to the former Target shareholders by Parent, other than regular
          or normal dividend distributions made with regard to all shares of
          Parent Common Stock.

     11.  None of the compensation received by any shareholder-employees of
          Target will be separate consideration for, or allocable to, any of
          their shares of Target Common Stock.  The compensation paid to any
          shareholder-employees of Target will be for services actually rendered
          and will be commensurate with amounts paid to third parties bargaining
          at arm's length for similar services.  None of the Parent Common Stock
          received by any shareholder-employee of Target will be in exchange
          for, or in consideration of, services rendered to Sub, Target or any
          other entity by such shareholder-employee.

     12.  The payment of cash in lieu of fractional shares of Parent Common
          Stock is solely for the purpose of avoiding the expense and
          inconvenience to Parent of issuing fractional shares and does not
          represent separately bargained-for consideration.  In addition, this
          cash payment will not be made pro rata either to all Target
          shareholders or to all Target and Parent shareholders.  The total cash
          consideration that will be paid in the Merger to Target shareholders
          in lieu of issuing fractional shares of Parent Common Stock will not
          exceed one percent of the total consideration that will be issued in
          the Merger to the Target shareholders in exchange for their shares of
          Target Common Stock.  The fractional share interests of each Target
          shareholder will be aggregated, and no Target shareholder will receive
          cash in an amount equal to or greater than the value of one full share
          of Parent Common Stock.

     13.  The Target shareholders that will receive cash in lieu of fractional
          shares of Parent Common Stock will not have control of Parent, for
          purposes of section 302(b)(1), following the Merger.

     14.  The Merger is being effected for bona fide business reasons as
          described in the Proxy Statement/Prospectus.

     15.  Prior to the Merger, Target will not sell or otherwise dispose of any
          of its assets, except for dispositions made in the ordinary course of
          business or transfers described in section 368(a)(2)(C) or Treasury
          Regulation Section 1.368-2(k).

     16.  Sub has no plan or intention to sell or otherwise dispose of any of
          the assets of Target to be acquired in the Merger, except for
          dispositions made in the ordinary course of business or transfers
          described in section 368(a)(2)(C) or Treasury Regulation Section
          1.368-2(k).

     17.  Prior to the Merger, Target will continue its historic businesses and
          will use a significant portion of its historic assets in those
          businesses.

     18.  Following the Merger, Sub will continue the historic business of
          Target and will use a significant portion of Target's historic
          business assets in a business.

                                       OPINION

Assuming that the Merger is consummated in accordance with the terms and
conditions set forth in the Merger Agreement and based on the facts set forth in
the Proxy Statement/Prospectus, the Letters, and this letter (including all
assumptions and representations), it is our opinion that for federal income tax
purposes:

1.   The Merger will constitute a "reorganization" within the meaning of section
     368(a), Parent, Sub and Target will each be a party to the reorganization
     within the meaning of Section 368 (b) of the Code.

2.   Neither Parent nor Sub will recognize gain or loss as a result of the
     Merger.

3.   Target will not recognize gain or loss as a result of the Merger.

4.   To the extent Target Common Stock is exchanged in the Merger for Parent
     Common Stock, no gain or loss will be recognized by the shareholders of
     Target.  The exchange of Parent or Target Stock for cash pursuant to the
     exercise of dissenters' rights will be a taxable transaction.

5.   The tax basis of the assets in Sub after the Merger will be the same as the
     tax basis of assets held by Target and Sub immediately before the Merger.

6.   The holding period for the shares of Parent Common Stock received by each
     shareholder of Target will include the holding period for the shares of
     Target Common of such shareholder exchanged in the Merger.

7.   The tax basis of the shares of Parent Common Stock received by each
     shareholder of Target will equal the tax basis of such shareholder's shares
     of Target Common Stock (reduced by any amount allocable to fractional share
     interests for which cash is received) exchanged in the Merger.

8.   The payment of cash to shareholders of Target in lieu of fractional share
     of interest of Parent will be treated as if the fractional shares were
     distributed as part of the exchange and then redeemed by Parent. These cash
     payments will be treated as having been received as a distribution in
     redemption of that fractional share interest subject to the conditions and
     limitations of Section 302 of the Code.   If a fractional share of Parent
     would constitute a capital asset in the hands of a redeeming shareholder,
     any resulting gain or loss will be characterized as a capital gain or loss
     in accordance with the provisions and limitations of Subchapter P of
     Chapter 1 of the Code.

9.   No gain or loss will be recognized for federal income tax purposes by the
     holders of outstanding stock options granted under Target's stock option
     plan as a result of the granting of substitute options granted pursuant to
     Parent's stock option plan.

10.  The granting of any substitute stock option to a holder of a Target stock
     option will not be deemed a modification of an incentive stock option.

Our opinion is limited to the foregoing federal income tax consequences of the
Merger, which are the only matters as to which you have requested our opinion,
and you must judge whether the matters addressed herein are sufficient for your
purposes.  We do not address any other federal income tax consequences of the
Merger or other matters of federal law and have not considered matters
(including state or local tax consequences) arising under the laws of any
jurisdiction other than matters of federal law arising under the laws of the
United States.

Our opinion is based on the understanding that the relevant facts are, and will
be on the Effective Date, as set forth in this letter.  If this understanding is
incorrect or incomplete in any respect, our opinion could be affected.  Our
opinion is also based on the Code, Treasury Regulations, case law, and Internal
Revenue Service rulings as they now exist.  These authorities are all subject to
change and such change may be made with retroactive effect.  We can give no
assurance that after any such change, our opinion would not be different.

We undertake no responsibility to update or supplement our opinion.
