                                                               December 21, 1994
    
 
Dear Stockholder:
 
     You are cordially invited to attend a Special Meeting of the Stockholders
of University Bank & Trust Company ("UBT"), which will be held at the offices of
UBT located at 250 Lytton Avenue, Palo Alto, California, at 4:30 p.m., local
time, on Wednesday, January 25, 1995 (the "Special Meeting").
 
     At the Special Meeting, UBT stockholders will be asked to consider and vote
upon a proposal (the "Merger Proposal") to approve and adopt the Agreement and
Plan of Reorganization and Merger, dated as of October 4, 1994 (the "Merger
Agreement"), by and among Comerica Incorporated, a Delaware corporation and a
registered bank holding company headquartered in Detroit, Michigan ("Comerica"),
Comerica Interim Incorporated, a California corporation ("Interim") and UBT,
providing for the merger (the "Merger") of Interim into UBT pursuant to the
terms of the Agreement of Merger (the "Subsidiary Merger Agreement"). UBT will
be the surviving corporation of the Merger. No other business will be transacted
at the Special Meeting.
 
     In the Merger, each fully diluted outstanding share of UBT Common Stock, no
par value (subject to certain provisions with respect to fractional shares and
dissenting shares) will be converted into the right to receive 1.7456 shares of
Comerica Common Stock, $5.00 par value per share (the "Comerica Common Stock"),
subject to certain adjustments described in the Merger Agreement.
 
     The proposed Merger requires, among other conditions, certain regulatory
approvals, as well as the approval of the stockholders of UBT.
 
     Your Board of Directors has determined that the Merger Agreement and the
Merger are in the best interests of UBT and its stockholders. THE BOARD
UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND THE MERGER AND RECOMMENDS THAT YOU
VOTE FOR APPROVAL OF THE MERGER PROPOSAL AT THE SPECIAL MEETING.
 
   
     The accompanying Notice and Proxy Statement/Prospectus describe the matters
to be acted upon at the Special Meeting. Stockholders are urged to review
carefully the attached Proxy Statement/Prospectus. This document contains a
detailed description of the Merger, its terms and conditions and the
transactions contemplated thereby. In addition, UBT's Annual Report on Form 10-K
for the year ended December 31, 1993 (the "Form 10-K"), UBT's Amendment No. 1 to
the Form 10-K on Form 10-K/A, UBT's Quarterly Report on Form 10-Q for the
quarterly period ended September 30, 1994 (the "Form 10-Q") and UBT's Amendment
No. 1 to the Form 10-Q on Form 10-Q/A have been enclosed.
    
 
     Because of the significance to UBT of the proposed Merger, your
participation in the Special Meeting, in person or by proxy, is especially
important. We urge you to vote FOR approval and adoption of the Merger Proposal.
 
     Your continuing interest in the business of UBT is appreciated, and we hope
you will attend the Special Meeting. It is important that your shares be
represented at the Special Meeting. Accordingly, whether or not you plan to
attend the Special Meeting, please sign, date and mail the enclosed Proxy
promptly in the postage-paid envelope that has been provided to you for your
convenience. If you wish to vote in accordance with the recommendations of your
Board of Directors, it is not necessary to specify your choices; you may merely
sign, date and return the enclosed Proxy.
 
                                               Sincerely,
 
   
                                               /s/ CARL J. SCHMITT

                   NOTICE OF SPECIAL MEETING OF STOCKHOLDERS
                         TO BE HELD ON JANUARY 25, 1995
 
     NOTICE IS HEREBY GIVEN that a Special Meeting of Stockholders of University
Bank & Trust Company will be held at UBT's offices located at 250 Lytton Avenue,
Palo Alto, California on January 25, 1995 at 4:30 p.m., local time (the "Special
Meeting"), for the following purposes, all of which are more fully described in
the accompanying Proxy Statement/Prospectus:
 
          To consider and vote upon a proposal (the "Merger Proposal") to adopt
     and approve (a) the Agreement and Plan of Reorganization and Merger, dated
     as of October 4, 1994 (the "Merger Agreement"), by and among Comerica
     Incorporated, a Delaware corporation and a registered bank holding company
     headquartered in Detroit, Michigan ("Comerica"), Comerica Interim
     Incorporated, a California corporation ("Interim"), and UBT, and (b) the
     Agreement of Merger (the "Subsidiary Merger Agreement"), providing for the
     merger (the "Merger") of Interim with and into UBT, and all of the
     transactions contemplated thereby, including but not limited to, the
     conversion, subject to certain provisions relating to fractional shares and
     dissenting shares, of each fully diluted outstanding share of common stock,
     no par value per share, of UBT ("UBT Common Stock") into the right to
     receive 1.7456 shares of common stock, $5.00 par value per share, of
     Comerica, subject to certain adjustments described in the Merger Agreement.
 
     The Merger Agreement and the Subsidiary Merger Agreement are set forth in
Annex A and Annex B, respectively, of the accompanying Proxy
Statement/Prospectus.
 
   
     Stockholders of UBT Common Stock may have dissenter's rights under
California law if their shares of UBT Common Stock qualify as "dissenting
shares" under California law. These rights may require UBT to purchase for cash
at fair market value from UBT stockholders any such "dissenting shares". UBT
stockholders must strictly comply with applicable California law to exercise
their dissenter's rights. A copy of the pertinent statutory provisions is
attached to this Proxy Statement/Prospectus as Annex C.
    
 
     The UBT Board of Directors has fixed the close of business on December 1,
1994, as the record date for the determination of UBT stockholders entitled to
notice of and to vote at the Special Meeting. Only UBT stockholders of record at
the close of business on such date are entitled to notice of, and to vote at,
the Special Meeting.
 
     The UBT Common Stock is the only security of UBT whose holders are entitled
to vote upon the proposals to be presented at the Special Meeting. Approval of
the Merger Proposal requires the affirmative vote of the holders of not less
than a majority of the outstanding shares of UBT Common Stock.
 
     Your vote is important regardless of the number of shares you own. Each
stockholder, whether he or she now plans to attend the Special Meeting, is
requested to sign, date and return the enclosed Proxy without delay in the
enclosed postage-paid envelope. You may revoke your Proxy at any time prior to
its exercise. Any stockholder present at the Special Meeting or at any
adjournments or postponements thereof may revoke his or her Proxy and vote
personally on each matter brought before the Special Meeting.

THE SPECIAL MEETING
 
     Special Meeting of Stockholders. A special meeting of the stockholders of
UBT will be held at the offices of UBT, located at 250 Lytton Avenue, Palo Alto,
California, on January 25, 1995, at 4:30 p.m., local time (the "Special
Meeting"). See "THE SPECIAL MEETING."
 
     Matters to Be Considered. At the Special Meeting, holders of UBT Common
Stock, no par value per share ("UBT Common Stock"), will consider and vote upon
a proposal (the "Merger Proposal") to adopt and approve (a) the Agreement and
Plan of Reorganization and Merger, dated as of October 4, 1994 (the "Merger
Agreement"), by and among UBT, Interim and Comerica, and (b) the Agreement of
Merger (the "Subsidiary Merger Agreement") providing for the merger (the
"Merger") of Interim with and into UBT, with UBT being the surviving entity. No
other matters will be brought before the Special Meeting. See "THE SPECIAL
MEETING -- Matters to Be Considered at the Special Meeting."
 
     Votes Required. The affirmative vote of the holders of a majority of the
outstanding shares of UBT Common Stock entitled to vote thereon is required to
approve the Merger Proposal. See "THE SPECIAL MEETING -- Vote Required."
 
     Record Date. The record date for the Special Meeting is December 1, 1994
(the "Record Date"). Only UBT stockholders of record at the close of business on
the Record Date are entitled to notice of, and to vote at, the Special Meeting.
 
                                        4
<PAGE>   12
 
   
     As of the Record Date, there were 1,407,597 shares of UBT Common Stock
outstanding, and each such share is entitled to one vote at the Special Meeting.
As of the Record Date, there were 495 holders of record of UBT Common Stock.
    
 
   
     Security Ownership. As of September 30, 1994, directors and executive
officers of UBT and their affiliates may be deemed to be the beneficial owners
of approximately 16.5% of the outstanding shares of UBT Common Stock. Such
officers and directors are entitled to exercise options to acquire a total of
11,000 shares of UBT Common Stock, which would result in such persons being
deemed to be the beneficial owners of approximately 17.3% of the shares of UBT
Common Stock outstanding as of September 30, 1994. See "THE MERGER -- Stock
Option Plans." Each UBT director who owns UBT Common Stock (each a "director-
stockholder") has executed an agreement which, among other things, obligates
each director-stockholder to vote the shares of UBT Common Stock owned or
controlled by them in favor of the Merger, subject to fiduciary obligations. See
"THE MERGER AGREEMENT -- Shareholder Agreements." As of the Record Date, the
director-stockholders of UBT owned or controlled an aggregate of 168,545 shares
of UBT Common Stock, representing approximately 11.97% of the then outstanding
shares of UBT Common Stock.
    
 
   
     As of the Record Date, no shares of UBT Common Stock were beneficially
owned by Comerica, Interim or any of their subsidiaries, directors or executive
officers, or their affiliates, excepting 400 shares of UBT Common Stock owned
jointly by a Comerica director and his wife.
    
 
THE MERGER
 
     Form of the Merger. Pursuant to the Merger Agreement, which is hereby
incorporated by reference and is set forth in Annex A to this Proxy
Statement/Prospectus, at the Effective Time (see "THE MERGER -- Effective Time
of Merger") of the Merger, Interim will merge with and into UBT, with UBT being
the surviving corporation in accordance with the terms of the Subsidiary Merger
Agreement. As a result of the Merger, Comerica will own the entire equity
interest in, and become the sole stockholder of, UBT. See "THE MERGER -- Form of
the Merger."
 
   
     Merger Consideration. Upon consummation of the Merger, each outstanding
share of UBT Common Stock will, subject to certain provisions with respect to
fractional shares and dissenting shares, be converted into the right to receive
1.7456 shares of Comerica Common Stock (based upon an assumed number of shares
of Fully Diluted UBT Common Stock (as defined in the Merger Agreement) of
1,591,186 as of the consummation of the Merger), subject to certain adjustments
described in the Merger Agreement (as so adjusted, the "UBT Conversion Rate").
The Merger Agreement provides for an adjustment to the UBT Conversion Rate in
the event that UBT's Consolidated Net Worth (as defined in the Merger Agreement)
is less than the sum of $34,200,000 and the Pre-Closing Income Amount (as
defined in the Merger Agreement), or in the event of certain changes in the
capitalization of Comerica, including, but not limited to, any recapitalization,
reorganization, stock split or stock dividend. In addition, all existing rights
with respect to UBT Common Stock pursuant to outstanding UBT stock options (the
"UBT Stock Options") under UBT Stock Option plans, whether vested or unvested or
exercisable shall be converted into and become rights with respect to Comerica
Common Stock and Comerica will assume each UBT Stock Option in accordance with
the terms of the UBT Stock Option plans and the stock option agreement, if any,
by which it is evidenced. In general, each UBT Stock Option holder will receive
the stock options for the number of shares of Comerica Common Stock such holder
would have been entitled to receive had such holder exercised his or her UBT
Stock Options in full immediately prior to the Effective Time, with appropriate
adjustment of the exercise price. See "THE MERGER -- Merger Consideration and --
Conditions to the Consummation of the Merger."
    
 
     Upon consummation of the Merger, each outstanding share of Interim will be
converted into one share of the surviving corporation.
 
   
     Effective Time of the Merger. It is expected that if the Merger Proposal is
approved by the UBT stockholders, and assuming that the other conditions
described in the Merger Agreement are satisfied, the Merger will become
effective during the first quarter of 1995. See "THE MERGER -- Effective Time of
Merger."

     If the Merger does not become effective on or prior to August 31, 1995, any
of Comerica, Interim or UBT may terminate the Merger Agreement. See "THE MERGER
AGREEMENT -- Termination."
 
   
     Purpose of the Merger and Comerica's Reasons for the Merger. The purpose of
the Merger is for Comerica to acquire the entire equity interest in UBT. It is
part of Comerica's current business strategy to expand its activities from
Michigan into states such as California where management believes there are
long-term opportunities which will benefit Comerica and its shareholders.
Comerica California Incorporated, a California corporation and registered bank
holding company, is Comerica's wholly owned bank holding company subsidiary
operating in the State of California, which through its wholly owned subsidiary,
Comerica Bank-California, a California bank, focuses on middle market banking,
small business banking, private banking, high technology, commercial real estate
lending and mortgage banker financing, as well as trust services, in the San
Jose and Los Angeles areas. See "THE COMPANIES -- Comerica Incorporated."
Comerica believes that through the Merger Comerica will be able to increase its
penetration of the California commercial, retail and private banking markets in
the communities served by UBT. This transaction is also expected to enhance the
competitiveness of the companies currently in the deregulated banking
environment and prospectively after the full impact of the Interstate Banking
and Branching Efficiency Act of 1994 (the "Interstate Act") is known. See "THE
MERGER -- Comerica Reasons for the Merger."; "CERTAIN REGULATORY CONSIDERATIONS
- -- Interstate Banking and Branching."
    
 
     Recommendations of the UBT Board of Directors and Reasons for the
Merger. The Board of Directors of UBT believes that the terms of the Merger are
fair to and in the best interests of UBT and its stockholders. All of the
members of the UBT Board were at the meeting approving the Merger Agreement and
they unanimously approved the Merger Agreement, the Subsidiary Merger Agreement
and the Merger. Accordingly, the UBT Board recommends that UBT stockholders vote
FOR the Merger Proposal. See "THE MERGER -- Recommendation of the Board of
Directors of UBT and Reasons for the Merger."
 
   
     The terms of the Merger Agreement, including the financial consideration
provided therein, were the result of arms' length negotiations between Comerica,
Interim and UBT and their respective representatives. In reaching a conclusion
to approve the Merger, the Board of Directors of UBT considered a number of
factors, including, but not limited to, the need to address the need for a
successor to its Chairman within the context of a consolidating banking industry
and a regulatory environment which is increasingly burdensome to smaller
institutions. See "THE MERGER -- Recommendation of the Board of Directors of UBT
and Reasons for the Merger" and "-- Background of the Merger."
    
 
   
     Opinion of Financial Advisor to UBT. Goldman, Sachs & Co. ("Goldman Sachs")
has served as financial advisor, and has delivered its written opinion to the
UBT Board, dated as of the date of this Proxy Statement/Prospectus, that the UBT
Conversion Rate to be received by UBT stockholders pursuant to the Merger
Agreement is fair to UBT stockholders. UBT has agreed to pay Goldman Sachs a fee
for their services which is in part contingent on the consummation of the
Merger. See "THE MERGER -- Opinion of UBT's Financial Advisor." The full text of
Goldman Sachs' written opinion, dated as of the date of this Proxy
Statement/Prospectus, which sets forth the assumptions made, matters considered
and limits on their review, is attached hereto as Annex D. UBT Common
Stockholders are urged to and should read such opinion in its entirety.
    
 
     UBT Acquisition Proposals. The Merger Agreement provides that UBT will not
authorize or knowingly permit any of its representatives, directly or
indirectly, to solicit or encourage, or participate in any discussions or
negotiations with, or provide any nonpublic information to, any person or group
of persons (other than Comerica, Interim or their representatives) concerning
any "Acquisition Proposal." An Acquisition Proposal is defined generally to mean
any proposal for the acquisition or participation in a merger or other business
combination involving UBT, any proposal by which any person or group other than
Comerica or Interim would acquire the right to vote 10% or more of the capital
stock of UBT entitled to vote for the election of directors, any acquisition of
the assets of UBT other than in the ordinary course of business, or any
acquisition of more than 10% of the outstanding capital stock of UBT. However,
UBT or its Board of Directors are not prevented from (A) furnishing non-public
information to, or entering into discussions or negotiations with, any person or
entity in connection with an unsolicited bona fide written Acquisition Proposal
by such person or entity or
 
                                        6
<PAGE>   14
 
   
recommending an unsolicited bona fide written Acquisition Proposal to the
shareholders of UBT, if and to the extent that (1) the Board of Directors of UBT
believes in good faith (after consultation with and the concurrence of its
financial advisor) that such Acquisition Proposal would, if consummated, result
in a transaction materially more favorable to UBT's stockholders from a
financial point of view than the transaction contemplated by the Merger
Agreement and the UBT Board of Directors determined in good faith after
consultation with its outside legal counsel that such action is necessary for
UBT to comply with its fiduciary duties to stockholders under applicable law,
and (2) prior to furnishing such non-public information to, or entering into
discussions or negotiations with, such person or entity, the UBT Board of
Directors received from such person or entity an executed confidentiality
agreement, with terms similar in scope to those contained in the confidentiality
agreement between Comerica and UBT, or (B) complying with Rule 14e-2 promulgated
under the Exchange Act of 1934, as amended, with regard to an Acquisition
Proposal. UBT is required to notify Comerica immediately upon receipt of any
inquiry regarding any Acquisition Proposal. See "THE MERGER -- Acquisition
Proposals."
    
 
   
     Conditions to the Merger; Termination. The obligations of Comerica, Interim
and UBT, as the case may be, to consummate the Merger are subject to various
conditions set forth in the Merger Agreement including, but not limited to,
obtaining requisite stockholder and regulatory approvals; the absence of any
materially burdensome condition imposed for any regulatory approval; the absence
of any action taken, or any statute, rule, regulation or order enacted, entered,
enforced or deemed applicable to the Merger by any governmental entity which
makes the Merger illegal, requires any material divestiture or imposes a
materially burdensome condition; the accuracy in all material respects of the
representations and warranties of, and performance in all material respects of
the covenants required to be performed prior to the Effective Time of the Merger
by, the other parties to the Merger Agreement; the absence of any materially
adverse change to the other parties or their subsidiaries; receipt of an opinion
of legal counsel in respect of certain Federal income tax consequences (see "THE
MERGER -- Certain Federal Income Tax Consequences"); receipt of legal opinions
and approval of their respective legal counsel of the transactions contemplated
by the Merger Agreement; approval for listing of the shares of the Comerica
Common Stock to be issued in the Merger on the New York Stock Exchange; and
receipt from each of Ernst & Young and KPMG Peat Marwick, LLP of letters, in
form and substance satisfactory to Comerica and UBT and customary in scope and
substance for letters delivered by independent public accountants in connection
with registration statements similar to the Registration Statement filed in
connection with the Merger. In addition, the obligations of Comerica and Interim
to consummate the Merger are subject to the following further conditions, among
others: the requirements that UBT's reserve for possible loan losses 5 business
days prior to the Effective Time shall be at least the greater of $4,700,000 or
2.25% of UBT's total loans outstanding on that date (subject to certain
adjustments) and that UBT's non-performing assets outstanding on the last day of
the month immediately preceding the Effective Time shall be no more than
$4,711,431. The obligation of UBT to consummate the Merger is subject to the
receipt of the written opinion of Goldman Sachs prior to the mailing of this
Proxy Statement/Prospectus, dated the date of this Proxy Statement/Prospectus to
the effect that, as of such date, the UBT Conversion Rate is fair. There can be
no assurance that the conditions to the Merger will be satisfied. See "THE
MERGER AGREEMENT -- Conditions to the Merger."
    
 
     Under certain circumstances, Comerica, Interim or UBT may terminate the
Merger Agreement, either prior to or after approval thereof by UBT stockholders.
See "THE MERGER AGREEMENT -- Termination."
 
   
     Liquidated Damages; Cancellation Fee. The Merger Agreement provides that,
in the event an Acquisition Event shall occur or (i) any of UBT, Comerica or
Interim terminates the Merger Agreement because the Merger Agreement, the
Subsidiary Merger Agreement and the Merger are not ratified by UBT's
stockholders, (ii) any of UBT, Comerica or Interim terminates the Merger
Agreement because there shall have been a material breach of any of the
representations or warranties set forth in the Merger Agreement on the part of
the other party, (iii) Comerica terminates the Merger Agreement because there is
a default by UBT, pursuant to the Merger Agreement and the continuance of such
failure for a period of 20 Business Days after written notice, which failure to
perform, in the reasonable opinion of Comerica and Interim cannot be cured prior
to the closing, or (iv) Comerica terminates the Merger Agreement because the UBT
Board did not publicly
    
 
                                        7
<PAGE>   15
 
recommend in this Proxy Statement/Prospectus that UBT stockholders adopt and
approve the Merger Agreement or shall withdraw, modify or amend such
recommendation in any respect materially adverse to Comerica followed by an
Acquisition Event within 90 days of such termination, UBT is required to pay to
Comerica the sum of $3,200,000 as reasonable and full liquidated damages and
reasonable compensation for the loss sustained thereby. For the purposes of the
Merger Agreement, an Acquisition Event is defined generally to mean (a) that UBT
has authorized, recommended, publicly proposed or publicly announced an
intention to authorize, recommend or propose, or entered into an agreement to
effect the following: a merger, consolidation or similar transaction involving
UBT or any of its subsidiaries; the disposition of assets of UBT or any of its
subsidiaries representing 15% or more of the consolidated assets of UBT and its
subsidiaries; or the issuance, sale or other disposition of securities
representing 10% or more of the voting power of UBT or any of its subsidiaries,
other than securities issued pursuant to the Stock Option Agreement, (b) the
acquisition of the beneficial ownership or the right to acquire beneficial
ownership by any person or group of persons (as the term "beneficial ownership"
is defined in Rule 13d-3 of the Securities Exchange Act of 1934) of 15% or more
of the outstanding UBT Common Stock; or (c) within 180 days after termination of
the Merger Agreement by Comerica upon the occurrence of certain events specified
in the Merger Agreement, where such events were caused in whole or in part by
any action or inaction within the control of UBT, any subsidiary of UBT or the
directors of UBT or UBT's subsidiaries.
 
   
     In addition, the Merger Agreement provides that, in the event of
termination by UBT of this Agreement because Interim or Comerica has breached
any of their representations and warranties set forth in the Merger Agreement
and in the reasonable opinion of UBT such breach cannot be cured prior to
closing and would have a Material Adverse Effect on Interim or Comerica or
because of a default by Comerica or Interim pursuant to the Merger Agreement and
the continuance of such failure for a period of 20 business days after written
notice of such default, in the reasonable opinion of UBT, cannot be cured prior
to the closing, then Comerica and Interim, jointly and severally, shall pay to
UBT as reasonable and full liquidated damages and reasonable compensation for
the loss sustained thereby and not as a penalty or forfeiture, the sum of
$2,000,000. See "THE MERGER AGREEMENT -- Liquidated Damages; Cancellation Fee."
    
 
     Regulatory Approvals Required. The Merger is subject to prior approval by
the Federal Reserve Board, the Commissioner of the Michigan Financial
Institutions Bureau (the "Michigan Commissioner") and the State of California's
Superintendent of Banks (the "California Superintendent"). Although it is not a
condition to consummation of the Merger, Comerica may, sometime after such
consummation, elect to merge the surviving corporation of the merger between UBT
and Interim with and into Comerica Bank-California, a wholly-owned subsidiary of
Comerica California Incorporated, Comerica's California bank holding company
(the "Subsidiary Bank Merger"). The Subsidiary Bank Merger would be subject to
prior approval of the Federal Deposit Insurance Corporation ("FDIC"), and the
California Superintendent. Applications for approval of the Merger have been
filed with the Federal Reserve, the Michigan Commissioner and the California
Superintendent. There can be no assurance that any of these regulatory
authorities will approve the Merger or the Subsidiary Bank Merger, or if
approved, as to the date of such approvals. There can also be no assurance that
such approvals will not contain a condition or requirement which causes such
approvals to fail to satisfy the conditions to the consummation of the Merger.
There can also be no assurance that the Department of Justice will not challenge
the Merger or the Subsidiary Bank Merger, or as to the outcome of any such
challenge if made. See "THE MERGER -- Conditions to the Consummation of the
Merger and -- Regulatory Approvals Required."
 
     Operations Pending the Merger. In the Merger Agreement, UBT has agreed to
carry on its business and the business of its subsidiaries in substantially the
manner as conducted prior to the execution of the Merger Agreement, to notify
Comerica promptly of any material adverse changes or events, to take certain
other actions, and to provide Comerica with certain reports and information. UBT
has also agreed in the Merger Agreement that it will not take certain actions,
including by way of example and not of limitation, issue capital stock (other
than pursuant to outstanding stock options under its Stock Option Plans), issue
other securities convertible into capital stock, acquire or dispose of material
assets, incur indebtedness other than in the ordinary course of business or
declare or pay any dividend, other than regular quarterly cash dividends in an
 
                                        8
<PAGE>   16
 
amount not to exceed $.35 per share. See "THE MERGER AGREEMENT -- Conduct of
Business Pending the Merger" and "THE MERGER -- Operations Pending the Merger."
 
   
     Operations After the Merger. If the Merger is consummated, UBT will be the
surviving corporation of the Merger, with the articles of incorporation of UBT
and the name University Bank & Trust Company. The separate existence of Interim
will cease, and the surviving corporation will continue as a wholly owned
subsidiary of Comerica. The Board of Directors of the surviving corporation will
be made up of certain directors of Interim and UBT serving in those capacities
at the Effective Time. It is anticipated that, upon consummation of the Merger,
Comerica will contribute the stock of the surviving corporation to Comerica
California Incorporated, Comerica's California bank holding company. At some
point after the consummation of the Merger the surviving corporation may merge
into Comerica Bank-California, a California bank and wholly owned subsidiary of
Comerica California Incorporated. At such time, the surviving corporation would
be run as a separate division of Comerica Bank-California.
    
 
     Following the consummation of the Merger, Carl J. Schmitt, Chairman of the
Board and Chief Executive Officer of UBT is expected to remain as Chairman of
the Board of the surviving corporation. It is also expected that Mr. Schmitt,
upon the anticipated Merger of the surviving corporation into Comerica Bank-
California, will become a member of the Board of Directors of Comerica
Bank-California and, as a result, will receive a fee for each board meeting he
attends, as well as reimbursement for expenses he incurs in doing so. See "THE
MERGER -- Interests of Certain Persons in the Merger."
 
     Banking policies and procedures of the surviving corporation and its
subsidiaries will continue in accordance with the policies of Comerica. See "THE
MERGER -- Operations After the Merger."
 
     Interests of Certain Persons in the Merger. Certain members of UBT's
management, including Mr. Carl J. Schmitt, may be deemed to have certain
interests in the Merger that are in addition to their interests as stockholders
of UBT generally. The UBT Board was aware of these interests and considered
them, among other matters, in approving the Merger Agreement and the
transactions contemplated thereby. See "THE MERGER -- Interests of Certain
Persons in the Merger" and -- "Operations After the Merger".
 
     Anticipated Accounting Treatment. The Merger is expected to be treated as a
purchase for accounting and financial reporting purposes. The shares of Comerica
Common Stock to be issued in the Merger will be authorized but unissued shares,
or shares held as treasury shares. Subject to the rules of the Commission,
Comerica may repurchase shares of Comerica Common Stock in open market or other
transactions to fund the Merger consideration. See "THE MERGER -- Anticipated
Accounting Treatment."
 
     Certain Federal Income Tax Consequences. The obligations of Comerica,
Interim and UBT to effect the Merger are conditioned upon the receipt of a legal
opinion dated the Effective Time of the Merger from legal counsel acceptable to
Comerica, subject to exceptions and assumptions normally included, and in form
and substance reasonably satisfactory to Comerica and UBT, to the effect that
the Merger will be treated for federal income tax purposes as a reorganization
within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "IRC"), and that Comerica, Interim and UBT will each be a party to
that reorganization within the meaning of Sections 368(a)(1)(A) and 368(a)(2)(E)
of the IRC. There can be no assurance that this opinion will be received. See
"THE MERGER -- Certain Federal Income Tax Consequences."
 
     The material federal income tax consequences of the proposed transactions
to stockholders of UBT are summarized under "THE MERGER -- Certain Federal
Income Tax Consequences."
 
     Stock Exchange Listing. The Comerica Common Stock is listed on the New York
Stock Exchange ("NYSE"). Comerica has agreed to apply for the listing of the
shares of Comerica Common Stock to be issued in the Merger on the NYSE. The
obligations of the parties to the Merger Agreement to consummate the Merger are
subject to approval for listing by the NYSE of such shares. See "THE MERGER --
Stock Exchange Listing."
 
     Dissenter's Rights. Holders of UBT Common Stock may have certain
dissenter's rights if their shares of UBT Common Stock qualify as "dissenting
shares" under California law. These rights may require UBT to
 
                                        9
<PAGE>   17
 
   
purchase for cash at fair market value from UBT shareholders any such
"dissenting shares." UBT stockholders must strictly comply with applicable
California law to exercise their dissenter's rights. A copy of the pertinent
statutory provisions are attached to this Proxy Statement/Prospectus as Annex C.
See "THE MERGER -- Dissenter's Rights."
    
 
   
     For additional information with respect to dissenter's rights and a
description of the procedure to exercise those rights, see "THE MERGER --
Dissenter's Rights."
    
 
   
     Stock Option Agreement. As a condition to entering into the Merger
Agreement, Comerica insisted that it be granted an option to purchase up to
137,718 shares of UBT Common Stock, representing approximately 9.9% of the
issued and outstanding shares of UBT Common Stock. UBT made such grant pursuant
to a separate Stock Option Agreement, dated October 4, 1994 (the "Stock Option
Agreement"). The per share exercise price of $38.25 was determined on the basis
of the average closing price of UBT Common Stock on the NASDAQ National Market
System for the seven trading days ending on October 4, 1994. The option may be
exercised only upon the occurrence of certain events and conditions. The Stock
Option Agreement is attached to this Proxy Statement/Prospectus as Annex E. See
"THE STOCK OPTION AGREEMENT."
    
 
     The Stock Option Agreement is intended to increase the likelihood that the
Merger will be consummated in accordance with the terms of the Merger Agreement.
Consequently, certain aspects of the Stock Option Agreement may have the effect
of discouraging persons who might now or prior to the Effective Time be
interested in acquiring all of or a significant interest in UBT from considering
or proposing such an acquisition, even if such persons were prepared to pay a
higher price per share for UBT Common Stock than the price per share implicit in
the UBT Conversion Rate or a higher price per share for UBT Common Stock than
the then current market price of such shares.
 
     Certain Regulatory Considerations. As financial institutions, Comerica and
its banking subsidiaries are subject to certain regulatory restrictions, and
examination and reporting requirements, of certain federal and state banking
authorities. Such restrictions impact, among other things, the payment of
dividends to Comerica by its bank subsidiaries and the extent to which Comerica
and its nonbank subsidiaries can borrow or otherwise obtain credit from its bank
subsidiaries. In addition, Comerica and its bank subsidiaries are subject to
certain capital requirements. Comerica is also expected to act as a source of
financial strength to each of its subsidiary banks and to commit resources to
support each of such subsidiaries. The regulatory structure applicable to banks
has been considerably revised by recent federal legislation. See "CERTAIN
REGULATORY CONSIDERATIONS."

     This Proxy Statement/Prospectus is being furnished to stockholders of
University Bank & Trust Company ("UBT") in connection with the solicitation of
proxies by the Board of Directors of UBT (the "UBT Board") for use at the
Special Meeting of Stockholders of UBT (the "Special Meeting") to be held at the
offices of UBT located at 250 Lytton Avenue, Palo Alto, California on January
25, 1995 at 4:30 p.m., and at any adjournments or postponements thereof.
 
   
     At the Special Meeting, the stockholders of UBT will be asked to consider
and vote upon a proposal (the "Merger Proposal") to adopt and approve (a) the
Agreement and Plan of Reorganization and Merger, dated as of October 4, 1994
(the "Merger Agreement"), by and among Comerica Incorporated, a Delaware
corporation and a registered bank holding company ("Comerica"), Comerica Interim
Incorporated, a California corporation ("Interim"), and UBT attached as Annex A
hereto and more fully described herein, and (b) the Agreement of Merger (the
"Subsidiary Merger Agreement"), attached as Annex B hereto, providing for the
merger (the "Merger") of Interim with and into UBT. UBT will be the surviving
corporation following the Merger, and will become a wholly-owned subsidiary of
Comerica.
    
 
   
     In the Merger, each outstanding share of common stock, no par value per
share, of UBT ("UBT Common Stock"), subject to certain provisions with respect
to fractional shares and dissenting shares, will be converted into the right to
receive 1.7456 of a share of common stock, $5.00 par value per share, of
Comerica ("Comerica Common Stock") (based upon an assumed number of shares of
Fully Diluted UBT Common Stock (as defined in the Merger Agreement) of 1,591,186
as of the consummation of the Merger), subject to certain adjustments described
in the Merger Agreement (the "UBT Conversion Rate"). In addition, all existing
rights with respect to UBT Common Stock pursuant to UBT stock option plans (the
"Stock Options"), whether vested or unvested or exercisable shall be converted
into and become rights with respect to Comerica Common Stock. Each UBT Stock
Option holder will receive the number of stock options for Comerica Common Stock
such holder would have received according to the UBT Conversion Rate as if such
holder exercised his or her UBT Stock Options in full immediately prior to the
Effective Date. See "THE MERGER -- Merger Consideration."
    
 
   
     The date on which this Proxy Statement/Prospectus is first being sent to
stockholders of UBT is on or about December 21, 1994.
    
 
                                 THE COMPANIES
 
COMERICA INCORPORATED
 
   
     General. Comerica is a registered bank holding company incorporated under
the laws of the State of Delaware, headquartered in Detroit, Michigan and was
formed in 1973 to acquire the outstanding common stock of Comerica Bank
(formerly Comerica Bank-Detroit), a Michigan banking corporation ("Comerica
Bank"). On June 18, 1992, Manufacturers National Corporation, a registered bank
holding company incorporated under the laws of the State of Delaware
("Manufacturers"), was merged with and into Comerica. Comerica was the surviving
corporation. The merger was accounted for as a pooling-of-interests. As of
September 30, 1994, Comerica owned directly or indirectly all the outstanding
common stock (except for directors' qualifying shares, where applicable) of 9
banking and 45 active nonbanking subsidiaries. At September 30, 1994, Comerica
had total assets of approximately $31.8 billion, total deposits of approximately
$20.3 billion, total loans (net of unearned income) of approximately $20.8
billion, and shareholders' equity of approximately $2.4 billion. At September
30, 1994, Comerica was the second largest bank holding company headquartered in
Michigan in terms of total assets.
    
 
     Comerica's business strategy focuses on five core businesses in four
geographic markets. Those businesses are corporate banking, consumer banking,
private banking, institutional trust and investment management, and
international finance and trade services. Corporate banking incorporates highly
specialized units servicing a full range of company sizes with both credit and
non-credit products. Consumer banking provides deposit, credit and fee-based
products to individuals needing financial services but whose income or wealth do
not make them prospects for private banking services. Private banking is
oriented to servicing the financial needs
 
                                       15
<PAGE>   23
 
of the affluent market as defined by individual net income or worth.
Institutional trust and investment management activities involve providing
companies, municipalities and other entities a wide spectrum of investment
management products and trust products such as master trust, master custody, and
corporate trust services, as well as administering and serving as trustee for
employee benefit plans. International finance and trade services offer importers
and exporters trade financing, letters of credit, foreign exchange and
international customhouse brokerage and freight forwarding products. The core
businesses are tailored to each of Comerica's four primary geographic markets:
the Midwest (currently Michigan and Illinois), Texas, California, and Florida.
The Midwest is the only market in which all five core businesses are currently
pursued. In California and Texas, the primary focus is on corporate banking and
private banking activities. In Florida, the primary focus is on private banking.
 
     On September 14, 1992, Comerica Bank, Comerica's principal banking
subsidiary, and Manufacturers Bank, N.A. (the principal banking subsidiary of
Manufacturers prior to its merger into Comerica on June 18, 1992) were merged,
with Comerica Bank being the surviving institution. Such merger was accounted
for using the pooling-of-interests method. At September 30, 1994, Comerica Bank
had approximately 282 branch offices in Michigan and total assets of
approximately $25.3 billion. At September 30, 1994, Comerica Bank was the second
largest commercial bank in Michigan in terms of deposits.
 
     In Illinois, Comerica owns Comerica Bank-Illinois. At September 30, 1994,
Comerica Bank-Illinois had 24 offices in Illinois and total assets of
approximately $1.5 billion.
 
   
     In Texas, Comerica owns Comerica Bank-Texas, which focuses on middle market
banking, small business banking, private banking and trust services in the
Dallas/Fort Worth, Texas area, and Lockwood National Bank of Houston which
provides similar services in the Houston area. At September 30, 1994, Comerica
Bank-Texas and Lockwood National Bank of Houston had total assets of
approximately $3.4 billion and 60 offices. See "Recently Completed Acquisitions"
for information regarding Lockwood National Bank of Houston, which was acquired
by Comerica on August 4, 1994.
    
 
   
     In California, Comerica owns Comerica Bank-California, which focuses on
middle market banking, small business and private banking, as well as trust
services, in the San Jose and Los Angeles areas. At September 30, 1994, Comerica
Bank-California had total assets of approximately $2.0 billion. It has 33
offices of which eleven are located in the San Francisco Bay Area. Comerica
Bank-California provides a wide array of services focused in middle market
banking, small business banking, high technology, commercial real estate lending
and mortgage banker financing. Comerica Bank-California also provides cash
management and trade finance services to corporate customers. It also targets
affluent and professional clients and provides customized solutions for their
private banking needs. Specialized banking services include lines of credit,
equipment loans, residential mortgage loans, equity lines of credit and consumer
loans. Comerica Bank-California offers fully managed trust accounts for
individuals and companies, and administration, record keeping, and investment
services for 401(k) plans and pension and profit sharing plans.
    
 
     Comerica serves trust and banking customers in Florida through Comerica
Bank & Trust, F.S.B., a federally chartered savings bank, which operates seven
offices and had approximately $160 million in assets at September 30, 1994.
 
     Competitors of Comerica's banking subsidiaries include commercial banks,
savings and loan associations, consumer and commercial finance companies,
leasing companies, credit unions and other financial services companies. Based
on the recent passage of the Interstate Banking and Branching Efficiency Act of
1994 (the "Interstate Act") and on legislation passed during 1985 that allows
Michigan-based banks to acquire or be acquired by banks in states with similar
laws in effect, Comerica believes that the level of competition will increase in
the future.
 
     Comerica's principal executive offices are located at Comerica Tower at
Detroit Center, 500 Woodward Avenue, Suite 3100, Detroit, Michigan 48226, and
its telephone number is (313) 222-4000.
 
     Recently Completed Acquisitions. On September 8, 1993, Comerica, Pacific
Western Bancshares, Inc., a Delaware corporation and a bank holding company
("PAC WEST"), Pacific Western Bank, a California state-chartered bank and a
wholly owned subsidiary of PAC WEST ("PWB") and Comerica California
 
                                       16
<PAGE>   24
 
   
Incorporated, a California registered bank holding company and wholly owned
subsidiary of Comerica ("COM CAL") entered into an Agreement and Plan of
Reorganization and Merger providing for, among other things, the merger of COM
CAL into PAC WEST with PAC WEST being the surviving corporation under the
charter and bylaws of COM CAL and the name "Comerica California Incorporated".
The merger was completed on March 30, 1994 and was accounted for as a purchase.
PAC WEST shareholders received common stock of Comerica valued at approximately
$121 million. At December 31, 1993, PAC WEST had assets of approximately $1
billion. PWB merged into Comerica Bank-California on June 30, 1994.
    
 
     On April 4, 1994, Comerica, Michigan National Corporation, a Michigan
corporation and a bank holding company ("MNC"), Lockwood Banc Group, Inc., a
Michigan corporation, wholly owned subsidiary of MNC and a registered bank
holding company ("Lockwood") and Lockwood National Bank of Houston, a national
banking association and wholly owned subsidiary of Lockwood ("LNB") entered into
a Stock Purchase Agreement whereby Comerica purchased from MNC all of the issued
and outstanding stock of Lockwood and LNB. The purchase was completed on August
4, 1994 for a purchase price of approximately $44 million in cash. At June 30,
1994 Lockwood had assets of approximately $318 million. Comerica contributed the
stock of LNB to Comerica Texas Incorporated its wholly owned bank holding
company in Texas. It is expected that LNB will merge into Comerica Bank-Texas in
the first quarter of 1995.
 
     Pending Joint Venture. On November 2, 1994, Comerica and Munder Capital
Management, Inc., a Delaware corporation and registered investment adviser
located in the Detroit, Michigan metropolitan area ("Munder"), entered into a
Joint Venture Agreement providing for the combination of the investment advisory
businesses of Munder and two investment advisory subsidiaries of Comerica:
Woodbridge Capital Management, Inc. ("Woodbridge") and World Asset Management,
Inc. ("World"). The Joint Venture Agreement contemplates the formation of a
partnership that will succeed to the investment advisory businesses of Munder,
Woodbridge, and World. Munder will hold a majority interest in the proposed
partnership, and Comerica will hold a minority interest. The venture is subject
to regulatory approval, which is expected by December 31, 1994.
 
     Future Acquisitions. Comerica continues to review and evaluate potential
acquisitions in order to expand its core businesses in defined markets. Comerica
anticipates that from time to time in the future it will acquire companies which
complement and effectuate Comerica's business objectives in both
federally-assisted and negotiated transactions. Certain bank acquisitions,
including those by Comerica and others have typically involved the payment of a
premium over book and market values, which may sometimes result in some dilution
to the acquiring company's book value and net income per common share. Comerica
expects that future acquisitions may involve acquisition premiums and dilution.
 
     Michigan Environmental Complaint. Manufacturers Bank (which was merged with
and into Comerica Bank in September, 1992) was served on July 24, 1990 with a
complaint by the Attorney General of the State of Michigan ("Plaintiff") in
which the Plaintiff sought to impose strict, joint, and several liabilities upon
Manufacturers Bank pursuant to the Comprehensive Environmental Response,
Compensation, and Liability Act ("CERCLA"), the Resource Conservation and
Recovery Act, and the Michigan Water Resources Commission Act. Plaintiff alleged
that Manufacturers Bank was an operator of certain facilities which have
environmental problems and that Manufacturers Bank had indicia of ownership
under CERCLA. The facilities involved were actually owned and operated by Auto
Specialties Manufacturing Company ("AUSCO"), now in bankruptcy. Plaintiff bases
the allegation upon the fact that two former Manufacturers Bank officers and
employees were members of the Board of Directors of AUSCO and that Manufacturers
Bank allegedly directed the installation of new management at AUSCO. Plaintiff
contends Manufacturers Bank had final and ultimate approval over AUSCO's
corporate strategies, policies and acquisitions.
 
     Plaintiff seeks cleanup costs and damages and has expressed the opinion
that the claim will be well in excess of $30 million. Comerica's management
believes that this action will not have a materially adverse effect on
Comerica's consolidated financial position, although it may, depending upon the
amount of ultimate liability, if any, and the consolidated results of operations
in the year of final resolution, have a materially adverse effect on the
consolidated results of operation in that year. On January 12, 1993, the United
States
 
                                       17

District Court for the Western District of Michigan granted Manufacturers Bank
its motion for summary judgment. The Plaintiff has filed an appeal to the Sixth
Circuit Court of Appeals.
 
UNIVERSITY BANK & TRUST COMPANY
 
     UBT is a California state bank organized in 1994 under the laws of the
State of California. The predecessor of UBT is University National Bank & Trust
Company, a national bank ("UNBT"), organized in 1980 under the federal laws of
the United States. On June 17, 1994, UNBT converted from a national bank charter
to a state charter, using the revised name of University Bank & Trust Company.
As a California state chartered bank which is also a member of the Federal
Reserve, UBT is governed by the California Financial Code and regulated by the
California Superintendent of Banks and the Federal Reserve Board. At September
30, 1994, UBT had total assets of approximately $442.2 million, total deposits
of approximately $403.5 million, total loans (net of unearned income) of
approximately $211.9 million, and stockholders' equity of approximately $35.4
million.
 
     UBT commenced operations on May 13, 1980. Since its formation, UBT has
provided basic banking services and personal trust services to individuals and
business enterprises in the Palo Alto area. Palo Alto is located on the San
Francisco Peninsula, approximately 30 miles south of San Francisco, on the
northern periphery of "Silicon Valley."
 
     UBT's primary service area is considered to be the communities of Palo
Alto, Menlo Park, Atherton and Portola Valley plus the unincorporated areas of
Ladera and Stanford University. This primary service area is oriented towards
professional services, light industry, retail businesses and education.
 
     UBT considers its principal service a "banking relationship," the keystone
of which is a transaction account. In the case of corporations, the transaction
account is a demand (checking) account. In the case of individuals, it is a
Super-NOW account that pays interest, provided that sufficient funds (i.e.,
either a daily minimum balance of $3,000 or an average monthly balance of
$6,000) are maintained. Once a customer has established the "relationship" with
UBT by opening a transaction account, that customer may utilize all other UBT
services, including money fund accounts, certificates of deposit, safe deposit
box rentals, cashier's checks, and the purchase of U.S. postage stamps, U.S.
Savings Bonds and traveler's checks. Borrowing clients who are low and moderate
income individuals are not expected to be deposit clients of UBT. UBT also makes
available to qualified customers commercial, personal and real estate loans,
credit cards and standby letters of credit. Through its correspondents, UBT is
also able to offer limited international banking and municipal bond trading
services.
 
     UBT's Trust Department specializes in personal trust services and acts as
trustee on a range of employee benefit plans. UBT does not provide stock
transfer services. UBT maintains a Trust Representative Office at 133 Mission
Street, Santa Cruz, California.
 
     UBT has an office at 800 Oak Grove, Menlo Park, California. UBT has
automatic teller machines at its two offices and it issues an automatic teller
machine "ATM" card which enables a customer to withdraw cash at over 65,000
offices of other financial institutions world wide which are members of Cirrus,
Money Network, Star System, American Express and the Interlink Network. UBT also
maintains an ATM machine at the Forum, 23500 Christo Rey Drive, Cupertino,
California.
 
     UBT is in the process of obtaining regulatory approval to open a new branch
in Los Altos, California.
 
     Competitors of UBT include commercial banks, savings & loan associations,
securities brokerage firms and credit unions.
 
     UBT's principal executive offices are located at 250 Lytton Avenue, Palo
Alto, California 94301, and its telephone number is (415) 327-0210.

                              THE SPECIAL MEETING
 
MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING
 
     At the Special Meeting, holders of UBT Common Stock will consider and vote
upon the Merger Proposal to approve and adopt the Merger Agreement, the
Subsidiary Merger Agreement and the Merger. No other matters will be brought
before the Special Meeting.
 
   
     ALL THE MEMBERS OF THE UBT BOARD WERE PRESENT AT THE MEETING APPROVING THE
MERGER AGREEMENT, AND THEY UNANIMOUSLY APPROVED THE MERGER AGREEMENT, THE
SUBSIDIARY MERGER AGREEMENT AND THE MERGER. THE UBT BOARD RECOMMENDS THAT UBT
STOCKHOLDERS VOTE FOR APPROVAL OF THE MERGER PROPOSAL.
    
 
VOTE REQUIRED
 
   
     The affirmative vote of the holders of at least a majority of the
outstanding shares of UBT Common Stock entitled to vote thereon is required to
approve the Merger Proposal. Each share of UBT Common Stock is entitled to one
vote. Thus, any shares of UBT Common Stock which for any reason, including
abstentions or broker non-votes, are not voted for approval of the Merger
Proposal will not count toward the required total and will have the same effect,
for purposes of approving the Merger Proposal, as shares voted against the
Merger Proposal. Approval of the Merger Proposal by the requisite vote of UBT
stockholders is a condition to, and required for, the consummation of the
Merger. See "THE SPECIAL MEETING -- Record Date; Shares Entitled to Vote;
Quorum."
    
 
SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS
 
     At September 30, 1994, UBT directors, executive officers and their
affiliates may be deemed to be the beneficial owners of approximately 230,551
shares of UBT Common Stock, representing approximately 16.5% of the then
outstanding shares of UBT Common Stock. Such officers and directors are entitled
to exercise options to acquire a total of 11,000 shares of UBT Common Stock,
which would result in such persons being deemed to be the beneficial owners of
approximately 17.3% of the shares of UBT Common Stock outstanding as of
September 30, 1994. See "THE MERGER -- Stock Option Plans." Each
director-stockholder of UBT has executed an agreement with Comerica which, among
other things, obligates them to vote the shares of UBT Common Stock owned or
controlled by them in favor of the Merger, subject to fiduciary obligations. See
"THE MERGER AGREEMENT -- Shareholder Agreements."
 
   
     As of the Record Date, no shares of UBT Common Stock were beneficially
owned by Comerica, Interim or any of their subsidiaries, directors or executive
officers, or their affiliates, excepting 400 shares of UBT Common Stock owned
jointly by a Comerica director and his wife.
    
 
VOTING OF PROXIES
 
   
     Shares of UBT Common Stock represented by properly executed proxies
received at or prior to the Special Meeting will be voted at the Special Meeting
in the manner specified by the holders of such shares. Properly executed proxies
which do not contain voting instructions will be voted FOR approval of the
Merger Proposal.
    
 
   
     If any other matters are properly presented at the Special Meeting for
consideration, including, among other things, consideration of a motion to
adjourn the Special Meeting to another time and/or place (including, without
limitation, for the purpose of soliciting additional proxies), the persons named
in the form of proxy enclosed herewith and acting thereunder will have
discretion to vote on such matters in accordance with their best judgment.
    
 
     UBT does not have any knowledge of any matters to be presented at the
Special Meeting other than those matters referred to and described herein.

<PAGE>   27
 
REVOCABILITY OF PROXIES
 
     The grant of a proxy on the enclosed form of proxy does not preclude a
stockholder from voting in person or otherwise revoking a proxy. Attendance at
the Special Meeting will not in and of itself constitute revocation of a proxy.
A stockholder may revoke a proxy at any time prior to its exercise by filing
with Gayle A. Anderson, Secretary of UBT, 250 Lytton Avenue, Palo Alto,
California 94301, a duly executed revocation or a proxy bearing a later date or
by voting in person at the Special Meeting.
 
RECORD DATE; SHARES ENTITLED TO VOTE; QUORUM
 
   
     Only holders of record of UBT Common Stock at the close of business on
December 1, 1994 (the "Record Date") will be entitled to receive notice of, and
to vote at, the Special Meeting. At the Record Date, UBT had outstanding
1,407,597 shares of UBT Common Stock. Holders of a majority of the outstanding
shares of UBT Common Stock entitled to vote must be represented in person or by
proxy at the Special Meeting in order for a quorum to be present at the Special
Meeting. As of the Record Date, there were 495 holders of record of outstanding
UBT Common Stock.
    
 
SOLICITATION OF PROXIES
 
     UBT will bear the cost of the solicitation of proxies from its
stockholders. In addition to solicitation by mail, the directors, officers and
employees of UBT may solicit proxies from their respective stockholders by
telephone or telegram or in person. Such persons will not be additionally
compensated, but will be reimbursed for reasonable out-of-pocket expenses
incurred in connection with such solicitation. Arrangements will also be made
with brokerage firms, nominees, fiduciaries and other custodians, for the
forwarding of solicitation materials to the beneficial owners of shares held of
record by such persons, and UBT will reimburse such persons for their reasonable
out-of-pocket expenses in connection therewith.
 
   
     UBT has retained the services of its transfer agent, First Interstate Bank
of California, to facilitate the distribution of solicitation materials and the
solicitation of proxies from banks, brokerage houses, fiduciaries and custodians
holding shares of UBT Common Stock in their names for beneficial holders. First
Interstate Bank of California may also solicit proxies from registered
stockholders. Solicitation would be made by mail, telephone and personal
contact. UBT will pay First Interstate Bank of California an estimated fee of
$5,000 for its services, plus its reasonable out-of-pocket costs.
    
 
                STOCKHOLDERS SHOULD NOT SEND STOCK CERTIFICATES
                             WITH THEIR PROXY CARDS
 
                                   THE MERGER
 
FORM OF THE MERGER
 
     Pursuant to the Merger Agreement, at the Effective Time (as defined below
under "Effective Time") of the Merger, Interim will merge with and into UBT,
pursuant to the terms of the Subsidiary Merger Agreement with UBT being the
surviving corporation. As a result of the Merger, Comerica will own the entire
equity interest in, and become the sole stockholder of, UBT.
 
MERGER CONSIDERATION
 
   
     UBT Conversion Rate. Upon consummation of the Merger, each outstanding
share of UBT Common Stock will be converted (subject to the provisions with
respect to fractional shares and dissenting shares described under "Conversion
of Shares; Procedures for Exchange of Certificates; Fractional Shares" and

     Net Worth (as defined in the Merger Agreement) at the Effective Time of the
     Merger is less than the sum of (i) $34,200,000, and (ii) the product
     obtained by multiplying $460,000 by the number of whole and fractional
     months beginning with September 1, 1994 and ending on the date upon which
     the Merger is consummated (the "Pre-Closing Income Amount");

     options contemplated by the Stock Option Agreement.
    
 
   
     Such amount, as adjusted, is referred to herein as the "UBT Conversion
Rate". THE UBT CONVERSION RATE OF 1.7456 DISCUSSED HEREIN ASSUMES NO ADJUSTMENT
IN THE NUMBER DETERMINED PURSUANT TO THE FOREGOING CLAUSE (A) AND THAT NUMBER OF
SHARES OF UBT COMMON STOCK DESCRIBED IN THE FOREGOING CLAUSE (B) IS 1,591,186.

     In addition, all existing rights with respect to UBT Common Stock pursuant
to UBT stock option plans (the "UBT Stock Options"), whether vested or unvested
or exercisable shall be converted into and become rights with respect to
Comerica Common Stock. Each UBT Stock Option holder will receive the number of
stock options for Comerica Common Stock such holder would have received
according to the UBT Conversion Rate as if such holder exercised his or her UBT
Stock Options in full immediately prior to the Effective Date.
    
 
     It is a condition to Comerica's obligation to consummate the Merger that
the number of shares of Comerica Common Stock that shall be issuable pursuant to
the terms of the Merger Agreement shall not exceed 2,680,820 as of the Effective
Time.
 
     The Merger Agreement also requires the UBT Conversion Rate to be further
appropriately adjusted to reflect any recapitalization, reorganization,
reclassification, split-up, merger, consolidation, exchange, stock or other
dividend or distribution (other than regular quarterly cash dividends) made,
declared or effective with respect to Comerica Common Stock between the date of
the Merger Agreement and the Effective Time of the Merger.
 
          There can be no assurance that an adjustment to the UBT Conversion
     Rate will not occur.
 
BACKGROUND OF THE MERGER
 
   
     UBT was founded in 1980 by its current Chairman and Chief Executive
Officer, Carl J. Schmitt. Since UBT's inception, Mr. Schmitt and certain of his
family members, as a group, have constituted the single largest shareholder
block of UBT, owning approximately 12% of the outstanding shares. For more
information regarding the business and history of UBT, and additional
information related to the stock ownership of UBT, see "THE COMPANIES --
University Bank & Trust Company."
    
 
     UBT has enjoyed steady growth and consistent earnings throughout its
history, and has been recognized in its market as an institution characterized
by personalized, high level customer service. The Board has attributed much of
the resulting success of UBT to the personal qualities and leadership style of
Mr. Schmitt. Beginning in late 1992 and early 1993, however, a series of events
began to heighten the Board's awareness of, and its need to address, certain
difficult issues facing UBT and its future.
 
     In 1992, the market served by UBT was working through a major recession.
While UBT weathered this recession, it highlighted some of the limitations of an
independent bank serving primarily a single geographic market.
 
                                       21
<PAGE>   29
 
     In early 1993, UBT underwent an intensive regulatory compliance examination
which also highlighted the increasing and, in management's view, disparate
burden of regulatory compliance on relatively small, niche-oriented institutions
like UBT.
 
     Also in early 1993, the need to identify a suitable successor to Mr.
Schmitt became more acute because he suffered a minor heart attack. Soon
thereafter, Mr. Schmitt made known his desire to begin planning for retirement
from the full time responsibilities of Chairman of the Board and Chief Executive
Officer. By the end of 1993, the convergence of these events caused the Board to
consider alternative courses of action.
 
     On January 19, 1994, the Board met in executive session for a lengthy
review of UBT's progress in the past and its prospects for the future,
particularly in light of Mr. Schmitt's desires. The trend of consolidation in
the banking industry was also discussed. After considerable discussion, the
Board analysis centered on two alternative strategies: (1) to engage an
investment banker to help determine the value of UBT were it to be sold, and (2)
to search for and evaluate possible successors to Mr. Schmitt to take office as
Mr. Schmitt commenced a phased-in retirement from the positions of Chairman and
CEO.
 
     Mr. Schmitt voiced his view that, based on his extensive knowledge of bank
executives familiar with UBT and its market (and knowledge of a number of bank
executives outside UBT's market), and on his efforts to inquire of the
availability of top management to move to UBT, he was not confident of UBT's
ability to identify a suitable successor. He also conveyed to the Board his
concern for the value of UBT and its franchise if he were to commence a
phased-in retirement without a successor having been identified.
 
   
     The Board concluded at the end of its January 19, 1994 meeting that UBT
should go forward with the strategy of engaging an investment banker of national
stature in the banking industry to assist in the valuation and potential sale of
UBT. Mr. Schmitt suggested, and the Board concurred, that contact should be
initiated with Goldman, Sachs & Co. ("Goldman Sachs").
    
 
     Mr. Schmitt travelled to New York in late January 1994 to meet with
representatives of Goldman Sachs. No agreements were signed and no conclusions
were reached at the meeting, although UBT agreed to provide additional
information to Goldman Sachs to enable Goldman Sachs to better understand UBT
and its value. Mr. Schmitt also acted during this period to engage the law firm
of Gray Cary Ware & Freidenrich in Palo Alto, California to serve as counsel to
UBT in the event of any sale or merger transaction.
 
     On March 17, 1994, the Board met again, this time joined by counsel and by
representatives of Goldman Sachs. Goldman Sachs made a presentation to the Board
regarding its credentials, a preliminary assessment of UBT's value, and an
overview of possible strategies for marketing UBT to prospective buyers.
Following the presentation, representatives of Goldman Sachs were excused from
the meeting, and the Board undertook an extensive discussion of the overall
question of whether to pursue sale or merger of UBT and if so, on what terms.
Several directors questioned whether now was the right time to pursue a sale or
merger, both in terms of UBT's present condition and in terms of the market for
bank mergers and acquisitions. There was discussion of the likely corporate
structure, regulatory requirements and timing of a possible sale or merger
transaction. There was also discussion of anticipated individual compensation to
Mr. Schmitt in the event of a sale or merger, as the Board recognized his unique
value to prospective buyers or merger partners, and also recognized that Mr.
Schmitt did not have any employment agreement or other agreement with UBT
providing him with compensation upon change in control of UBT. At the conclusion
of this meeting, Mr. Schmitt was authorized to engage Goldman Sachs to
investigate and pursue sale or merger opportunities.
 
     Goldman Sachs promptly commenced a due diligence review of UBT, including
an examination of financial results, management's financial projections,
competitive position and market share, deposit profile, liquidity, interest rate
exposure, loan portfolio and fixed assets and other matters in order to
determine the range of fair value for UBT. Goldman Sachs prepared a confidential
descriptive memorandum (the "Confidential Memorandum") about UBT and, based on
its extensive knowledge of, and contacts within, the banking industry
nationwide, selected parties that might be interested and able to acquire UBT.
Of the parties discussed, a list of twenty-two institutions was developed which
Goldman Sachs and management agreed would represent the most attractive
potential merger partners. Goldman Sachs contacted these institutions
 
                                       22
<PAGE>   30
 
(without identifying UBT by name) to see if there was sufficient interest by any
of them to sign a confidentiality agreement and receive a copy of the
Confidential Memorandum.
 
     On May 19, 1994, the Board met again, and Mr. Schmitt gave a progress
report on the efforts of Goldman Sachs. The institutions which were interested
in receiving a Confidential Memorandum were discussed, although it was
recognized that there were additional contacts to be made.
 
     By the middle of June 1994, it had been determined that of the twenty-two
institutions contacted, nine were willing to sign a confidentiality agreement
and review the Confidential Memorandum. The other institutions decided for
various reasons not to pursue the opportunity to acquire UBT.
 
     Mr. Schmitt invited each of the nine institutions which had signed the
Confidentiality Agreement to meet with him prior to submitting any proposal.
Over the next several weeks, Mr. Schmitt, together with one or more
representatives of Goldman Sachs, had personal meetings to explain the
philosophy of UBT and respond to any questions with the five interested parties
(including Comerica) which requested such meetings.
 
     Following those meetings, on June 30, 1994, a letter was sent to nine
interested parties requesting that they submit non-binding indications of
interest by July 6, 1994. Three institutions responded to the request for
non-binding indications of interest. Of the three, one of the indications was
delivered orally and subsequently was withdrawn. Both written indications
included a price or range of prices for UBT. After consultation with Goldman
Sachs and input from Board members, Mr. Schmitt directed Goldman Sachs to go
back to both institutions and inform them that, while each of their respective
proposals were compelling in many respects, including perceived cultural fit and
reputation, the offers did not adequately reflect the value of UBT's franchise.
Both institutions were instructed that if they could offer consideration of at
least $50.00 per share, Mr. Schmitt and Goldman Sachs felt it appropriate to
continue discussions and for either, or both, institution to spend additional
time familiarizing themselves with UBT, its earnings record, and its prospects
for 1995. As a result of such discussions, only Comerica elected to continue in
the process.
 
     On July 21, 1994, the Board met and received another update on the selling
effort. At this time only Comerica had indicated a willingness to consider a
price valued at $50 per share for the outstanding shares (and options) of UBT.
Additional efforts by Goldman Sachs to re-introduce the second bidder into the
process were unsuccessful. The Board directed Mr. Schmitt to continue his
discussion with Comerica to determine if an acceptable proposal could be
forthcoming.
 
     During August 1994, a number of meetings with Comerica were held by Mr.
Schmitt and representatives of Goldman Sachs. On August 3, 1994, Mr. Schmitt met
in California with the Vice Chairman of Comerica, along with the Chairman and
the President of Comerica Bank-California. This meeting was focused on gaining a
better understanding of the operating philosophies of the two institutions.
Further, similar discussions took place on August 16, when Mr. Schmitt met with
senior management of Comerica at Comerica's headquarters offices in Detroit.
 
     On August 17, 1994, Mr. Schmitt met with senior members of UBT's management
team to inform them of the discussions with Comerica, and of a meeting scheduled
for the following day between them and their counterparts at Comerica
Bank-California. The August 18, 1994 meeting was held at the offices of Goldman
Sachs in San Francisco. Following this meeting, negotiations were broken off at
the direction of Mr. Schmitt.
 
     On August 22, 1994, Goldman Sachs informed Mr. Schmitt that Comerica had
requested an additional meeting to explore the reasons Mr. Schmitt had broken
off discussions and determine if the problems could be resolved. Later that
week, the meeting was held among Mr. Schmitt, a representative of Goldman Sachs,
the Chairman and the President of Comerica Bank-California. Mr. Schmitt
suggested at that meeting that another meeting be held among only management
representatives of the two institutions, to determine if his concerns about
preserving the franchise value of UBT could be reconciled with Comerica's
concerns for consistent and attractive earnings. This additional meeting was
held the following week, and although no agreements were reached, Mr. Schmitt
came away believing that substantial progress had been made toward better
understanding of the subjective aspects of UBT's value and the keys to
preserving and enhancing that value in the future.
 
                                       23
<PAGE>   31
 
     On September 15, 1994, UBT's Board of Directors met again in executive
session to receive a full briefing on the status of negotiations with Comerica,
and to reconsider the question of whether any sale or merger was the right step
at that time. The status report delivered by Mr. Schmitt indicated Comerica had
at that time offered $50 per UBT share, subject to satisfactory completion of
due diligence. Mr. Schmitt had countered at a flat exchange rate of 1.7 shares
of Comerica stock, which at the time equalled more than $50 per share based on
the then prevailing Comerica share price. No resolution had been reached on this
issue by Mr. Schmitt and Comerica.
 
     The Board again considered the appropriateness of a potential sale, at that
time in the context of having a bona fide buyer seriously interested in
acquiring UBT. Although the possible adverse impacts of a sale or merger on the
community were recognized as a negative aspect of any transaction, concerns over
the successorship issue regarding Mr. Schmitt, the disparate impact of the
increasing regulatory burden on smaller banks, and the consolidation trend
sweeping the industry were all viewed as persuasive in favor of proceeding with
a transaction if the terms could be successfully negotiated. At the conclusion
of the meeting, the Board voted unanimously to go forward and have Mr. Schmitt
attempt to negotiate an acceptable final price.
 
     The next day, September 16, 1994, the parties agreed on a fixed share
exchange ratio, subject to a downward adjustment under certain circumstances,
based on an average of the closing price of Comerica common stock for the period
from September 12, 1994 until two days before signing a definitive agreement to
merge. The parties also agreed on a schedule for Comerica to conduct its due
diligence while negotiations for the definitive agreement were ongoing.
 
   
     On September 24, 1994, Mr. Schmitt met with the Chairman of the Board and
the President of Comerica Bank-California to discuss the terms of a severance
package and a proposed covenant not to compete from Mr. Schmitt, as well as Mr.
Schmitt's continuing commitment to assist UBT following any merger. Mr. Schmitt
set forth his needs and expectations with respect to compensation for such an
arrangement. Tentative agreement was reached calling for a payment at closing of
the Merger of $1 million in severance and a payment of approximately $1.2
million in exchange for Mr. Schmitt's agreement not to compete in Santa Clara
and Santa Cruz counties in California, and in exchange for his agreement to
continue as Chairman of the Board of the surviving company.
    
 
     On September 26, 1994 Mr. Schmitt, together with a representative of
Goldman Sachs, met in Detroit, Michigan with senior management of Comerica to
conduct due diligence on the current financial condition and future prospects
for Comerica. During this time, Comerica's due diligence on UBT also proceeded,
and counsel for the parties worked on the terms of a definitive agreement, which
by September 30, 1994 was in substantially final form.
 
     On October 2, 1994, the UBT Board members met with representatives of
Goldman Sachs and legal counsel to review the status of negotiations and the
terms of the proposed Merger Agreement. Goldman Sachs gave a detailed review of
the sale process, the terms and conditions of the proposed final agreement
relative to other bank merger transactions, and concluded with its oral opinion
that the terms, as proposed in the most recent draft of the Agreement, were fair
to UBT's stockholders from a financial point of view. Legal counsel briefed the
Board on the material terms of the proposed definitive agreement, including the
mutual breakup fees, the lock up option, as well as the proposed terms of a
Non-Competition Agreement between Mr. Schmitt and Comerica. At the conclusion of
the meeting, Board members voted unanimously to approve the Merger Agreement,
the Subsidiary Merger Agreement and the transactions contemplated thereby,
including, but not limited to, the Merger and the proposed Non-Competition
Agreement to be entered into by Mr. Schmitt, but reserved for themselves a 24
hour period in which to reconvene if any director felt differently the following
day.
 
     No director called for a reconvening of the Board meeting, and on October
4, 1994 the Merger Agreement was executed by the parties.
 
   
     The Comerica Board approved the Merger and authorized execution of the
Merger Agreement on September 16, 1994.

COMERICA REASONS FOR THE MERGER
 
     It is part of Comerica's current business strategy to expand its activities
from Michigan into states such as California where management believes there are
long-term opportunities which will benefit Comerica and its shareholders.
Comerica California Incorporated is Comerica's wholly-owned bank holding company
subsidiary operating in the State of California, which through its wholly owned
subsidiary, Comerica Bank-California, focuses on middle market banking, small
business banking, private banking and trust services in the San Francisco Bay
and San Jose areas. See "THE COMPANIES -- Comerica Incorporated -- General."
Comerica believes that through the Merger Comerica will be able to increase its
penetration of the California commercial, retail and private banking markets in
the communities served by UBT. This transaction is also expected to enhance the
competitiveness of the companies in a deregulated banking environment.
 
     In addition, Comerica believes that in light of the acceleration in the
number and size of combinations currently occurring within the financial and
banking industries and the promulgation of the Interstate Act will provide
further impetus to consolidation of banking entities, it is desirable for
Comerica to expand its financial resources and markets.
 
RECOMMENDATIONS OF THE BOARD OF DIRECTORS OF UBT AND UBT REASONS FOR THE MERGER
 
   
     The UBT Board has determined that the Merger Agreement is in the best
interests of UBT and its stockholders, and unanimously recommends that the UBT
Common Stockholders approve the Merger Proposal. In arriving at its conclusion,
the UBT Board was influenced by the factors discussed above under "Background of
Merger", namely the need to address the need for a successor to its Chairman
within the context of a consolidating banking industry and a regulatory
environment which is increasingly burdensome to smaller institutions. The UBT
Board also considered several additional factors, though the Board did not
assign any specific or relative weight to these factors in its considerations.
Additional factors considered by the Board included the following:
    
 
          (i) the fact that the due diligence examination conducted by
     representatives of UBT, including Goldman Sachs, indicated that Comerica is
     strong in capital, earnings and management, and has good regulatory
     relationships, and a compatible operating philosophy with UBT;
 
          (ii) the opinion of Goldman Sachs that the UBT Conversion Rate is fair
     to the stockholders of UBT;
 
          (iii) the fact that the Merger will be tax-free for federal income tax
     purposes for the stockholders of UBT Common Stock (other than in respect to
     cash paid in lieu of fractional shares);
 
          (iv) the likelihood that the Merger would result in receipt of
     substantially increased dividends to stockholders of UBT Common Stock who
     keep their shares of Comerica Common Stock after the Merger;
 
          (v) the market liquidity afforded by the listing of shares of Comerica
     Common Stock on the NYSE compared to the minimal trading of UBT's Common
     Stock;
 
          (vi) the Board's review with its legal advisors and with Goldman Sachs
     of the provisions of the Merger Agreement; and
 
          (vii) the probable impact of the Merger on employees and customers of
     UBT.
 
OPINION OF UBT'S FINANCIAL ADVISOR
 
     Pursuant to an engagement letter dated March 17, 1994 (the "Engagement
Letter"), UBT retained Goldman Sachs as its exclusive financial advisor in
connection with reviewing UBT's strategic alternatives, including a possible
sale of UBT. Goldman Sachs is an internationally recognized investment banking
firm and is continually engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, competitive biddings, secondary distributions of listed and
unlisted
 
                                       25
<PAGE>   33
 
securities, private placements and valuations for estate, corporate and other
purposes. Goldman Sachs is familiar with UBT, having acted as financial advisor
in connection with, and having participated in certain of the negotiations
leading to, the Merger Agreement. Goldman Sachs has also provided certain
investment banking services to Comerica from time to time and may provide
investment banking services to Comerica in the future. The UBT Board selected
Goldman Sachs to act as UBT's exclusive financial advisor based on Goldman
Sachs' substantial experience in mergers and acquisitions and in securities
valuation generally.
 
   
     THE FULL TEXT OF THE GOLDMAN SACHS WRITTEN OPINION DATED AS OF THE DATE OF
THIS PROXY STATEMENT/PROSPECTUS, WHICH SETS FORTH THE ASSUMPTIONS MADE, MATTERS
CONSIDERED AND LIMITS ON THEIR REVIEW, IS ATTACHED HERETO AS ANNEX D. HOLDERS OF
SHARES OF UBT COMMON STOCK ARE URGED TO AND SHOULD READ SUCH OPINION IN ITS
ENTIRETY.
    
 
     In connection with its opinion dated as of the date of this Proxy
Statement/Prospectus, Goldman Sachs reviewed, among other things, the Merger
Agreement; the Registration Statement on Form S-4, including this Proxy
Statement/Prospectus relating to the Special Meeting to be held in connection
with the Merger Agreement; Annual Reports to Stockholders and Annual Reports on
Form 10-K of UBT for the two years ended December 31, 1993; Annual Reports to
Stockholders and Annual Reports on Form F-2 of UBT for the three years ended
December 31, 1991; Annual Reports to Stockholders and Annual Reports on Form
10-K of Comerica for the five years ended December 31, 1993; certain interim
reports to stockholders and Quarterly Reports on Form 10-Q of UBT and Comerica;
certain other communications from UBT to its stockholders; and certain internal
financial analyses and forecasts for UBT prepared by its management. Goldman
Sachs also held discussions with members of the senior managements of UBT and
Comerica regarding the past and current business operations, financial condition
and future prospects of their respective companies. In addition, Goldman Sachs
has reviewed the reported price and trading activity for UBT Common Stock,
compared certain financial and stock market information with similar information
for certain other companies the securities of which are publicly traded,
reviewed the financial terms of certain recent business combinations in the
banking industry specifically and in other industries generally and performed
such other studies and analyses as Goldman Sachs considered appropriate.
 
     Goldman Sachs relied, without independent verification, upon the accuracy
and completeness of all of the financial and other information reviewed by it
for purposes of its opinion. In that regard, Goldman Sachs assumed, with the
consent of the UBT Board, that the financial forecasts, including, without
limitation, projections regarding underperforming and nonperforming assets and
net chargeoffs were reasonably prepared on a basis reflecting the best currently
available judgments and estimates of UBT and that such forecasts would be
realized in the amounts and at the times contemplated thereby. Goldman Sachs is
not an expert in the evaluation of loan and lease portfolios for purposes of
assessing the adequacy of the allowances for losses with respect thereto and has
assumed, with the consent of the UBT Board, that such loss allowances for each
of UBT and Comerica are in the aggregate adequate to cover all such losses.
Goldman Sachs did not review individual credit files nor did it make an
independent evaluation or appraisal of the assets and liabilities of UBT or
Comerica or any of their respective subsidiaries. Goldman Sachs also has assumed
that Comerica will receive all necessary regulatory approvals without undue
delay.
 
     Pursuant to the terms of the Engagement Letter, UBT has agreed to pay
Goldman Sachs a transaction fee equal to 1.5% of the aggregate consideration
paid in such transaction or approximately $1.15 million. In addition, UBT has
agreed to reimburse Goldman Sachs for its reasonable out-of-pocket expenses,
including the fees and disbursements of its counsel, plus any sales, use or
similar taxes arising in connection with its engagement, and to indemnify
Goldman Sachs against certain liabilities relating to or arising out of its
engagement, including liabilities under the federal securities laws.
 
SUMMARY OF FINANCIAL ANALYSES
 
   
     The following is a summary of the material financial analyses utilized by
Goldman Sachs in connection with providing its written opinion dated as of the
date of this Proxy Statement/Prospectus to the UBT Board but does not purport to
be a complete description of the analyses performed by Goldman Sachs.
    
 
                                       26
<PAGE>   34
 
   
     Pro Forma Analysis. Goldman Sachs analyzed certain pro forma effects for
1995 resulting from the Merger based on (i) financial forecasts for UBT prepared
by UBT management, (ii) projected earnings for Comerica based on the median of
institutional brokers' estimates compiled by SNL Securities, L.P. as of December
1, 1994 (SNL Securities, L.P. is a data firm that monitors and publishes a
compilation of earnings estimates produced by selected research analysts), and
(iii) cost savings equal to 10% of UBT's estimated 1994 noninterest expense,
estimated by management of UBT to be attainable in the Merger.
    
 
   
     Selected Transaction Analysis. Goldman Sachs analyzed certain information
relating to 19 bank and thrift acquisitions, including nine bank acquisitions in
the states of Arizona, California, Colorado, Oklahoma and Texas announced since
January 1, 1992 in which the aggregate consideration was greater than $25
million and less than $100 million (the "Western U.S. Bank Acquisitions") and
ten acquisitions by Comerica announced since January 1, 1988 (the "Comerica
Acquisitions"). Such analysis indicated that, for the Western U.S. Bank
Acquisitions and the Comerica Acquisitions, (i) the median values of the
consideration paid as a multiple of tangible book value were 1.9x and 1.9x,
respectively, as compared to a corresponding value for the consideration payable
pursuant to the Merger as a multiple of UBT's tangible book value of 1.8x; (ii)
the median values of the adjusted consideration paid as a multiple of adjusted
tangible book value (where both consideration and tangible book value are
adjusted to eliminate excess capital, defined as capital in excess of a 6.00%
tangible common equity to tangible assets) were 2.0x and 1.9x, respectively, as
compared to a corresponding value for the adjusted consideration payable
pursuant to the Merger as a multiple of UBT's adjusted tangible book value of
2.1x, and; (iii) the median value of the consideration paid as a multiple of the
acquired banking organizations' latest twelve months' ("LTM") after-tax earnings
were 11.0x and 13.4x, respectively, as compared to the corresponding value for
the consideration paid pursuant to the Merger as a multiple of UBT's after-tax
LTM earnings of 13.6x.
    
 
   
     Selected Company Analysis. Goldman Sachs reviewed and compared actual and
estimated selected financial, operating and stock market information for UBT
with corresponding information for selected mid-capitalization banking
organizations located in California, including CVB Financial Corporation,
California Bancshares, Inc., City National Corporation, Imperial Bancorp, Santa
Barbara Bancorp, Silicon Valley Bancshares and Westamerica Bancorp
(collectively, the "Selected Group One Banks"), and for selected
large-capitalization organizations headquartered in California, including
BankAmerica Corporation, First Interstate Bancorp and Wells Fargo & Company
(collectively, the "Selected Group Two Banks"), based on publicly available
information, consensus analysts' estimates for the Selected Group One Banks and
the Selected Group Two banks and financial forecasts for UBT prepared by
management. Such analysis indicated, among other things, that for the Selected
Group One Banks and the Selected Group Two Banks, (i) the median estimated 1995
price-earnings multiples were 9.0x and 7.0x, respectively, as compared to a
corresponding value of 8.8x for UBT, (ii) the median values of price as a
multiple of tangible book value per share were 1.4x and 1.8x, respectively, as
compared to a corresponding value of 1.5x for UBT, (iii) the median ratios of
nonperforming assets as a percentage of total loans and other real estate owned
were 2.10% and 1.50%, respectively, as compared to 2.31% for UBT, (iv) the
median ratios of loan loss reserves as a percentage of nonperforming loans were
140% and 329%, respectively, as compared to 346% for UBT, (v) the median
after-tax returns on equity were 9.3% and 21.5%, respectively, as compared to
14.4% for UBT, and (vi) the median ratios of tangible common equity as a
percentage of tangible assets were 7.94% and 5.47%, respectively, as compared to

     Selected Comerica Information Analysis. Goldman Sachs reviewed and analyzed
certain financial and other information for Comerica, including (i) historical
and current loan portfolio by type of loan, (ii) deposit market share by state
in the United States and by county in California, (iii) a comparison of actual
and estimated selected financial, operating and stock market information for
Comerica with corresponding information for selected super-regional banking
organizations, including Banc One Corporation, Boatmen's Bancshares, Inc.,
Corestates Financial Corporation, First Bank System, Inc., First Interstate
Bancorp, Mellon Bank Corporation, NBD Bancorp, Inc., National City Corporation,
Norwest Corporation, PNC Bank Corporation, U.S. Bancorp and Wells Fargo &
Company (collectively, the "Selected Super-Regional Banks"), (iv) the daily
stock price performance of Comerica Common Stock, the Standard & Poor's 500
Stock Index and a composite of the Selected Super-Regional Banks, all indexed
daily from December 2, 1993

to December 2, 1994, weekly from December 2, 1991 to December 2, 1994 and
monthly from November 30, 1989 to November 30, 1994, (v) historical trading
prices per share and trading volume of Comerica Common Stock, on a daily basis
from December 2, 1993 through December 2, 1994, on a weekly basis from December
2, 1991 through December 2, 1994 and on a monthly basis from November 30, 1984
to November 30, 1994, and (vi) summaries of selected research reports on, and
earnings estimates for, Comerica.
    
 
     Other Analyses. Goldman Sachs also analyzed available information regarding
the ownership and ownership profiles of shares of UBT Common Stock and Comerica
Common Stock.
 
     General. The foregoing is a summary of the material financial analyses
performed by Goldman Sachs, but does not purport to be a complete description of
the analyses performed by Goldman Sachs. The preparation of a fairness opinion
is a complex process and is not necessarily susceptible to partial analysis or
summary description. Selecting portions of the analyses or of the summary set
forth above, without considering the analysis as a whole, could create an
incomplete view of the processes underlying Goldman Sachs' opinion. In arriving
at their fairness determination, Goldman Sachs considered the results of all
such analyses. No Selected Group One Bank or Selected Group Two Bank is
identical to UBT and none of the Western U.S. Bank Acquisitions or the Comerica
Acquisitions, is identical to the Merger. Accordingly, Goldman Sachs indicated
to the UBT Board that analyses of the results described above under Selected
Transaction Analysis and Selected Company Analysis are not mathematical, but
rather involve complex considerations and judgments concerning differences in
operating and financial characteristics including, among other things,
differences in revenue composition and earnings performance among UBT, Comerica
and the selected companies and transactions reviewed. The analyses were prepared
solely for purposes of Goldman Sachs' providing their written opinion dated as
of the date of this Proxy Statement/Prospectus, to the UBT Board as to the
fairness of the UBT Conversion Rate, and do not purport to be appraisals or
necessarily reflect the prices at which UBT or its securities actually may be
sold. Analyses based upon forecasts of future results are not necessarily
indicative of actual future results, which may be significantly more or less
favorable than suggested by such analyses.
 
EFFECTIVE TIME OF MERGER
 
     The Merger will become effective as to UBT at the time (the "Effective
Time") when an appropriate certificate of merger and the Subsidiary Merger
Agreement with respect to the Merger are filed with the Secretary of State of
the State of California. It is currently anticipated that if the Merger is
approved by UBT stockholders at the Special Meeting, and all the other
conditions to the Merger are satisfied, the Merger will become effective during
the first quarter of 1995.
 
     There can be no assurance, however, that the Effective Time will not be
delayed. In the event the Merger has not become effective by August 31, 1995,
the Board of Directors of Comerica, UBT or Interim, as applicable, may terminate
the Merger Agreement notwithstanding any approvals previously given by the
stockholders of UBT. See "THE MERGER AGREEMENT -- Termination."
 
CONVERSION OF SHARES; PROCEDURES FOR EXCHANGE OF CERTIFICATES; FRACTIONAL SHARES
 
     The conversion of outstanding shares of UBT Common Stock into shares of
Comerica Common Stock will occur automatically at the Effective Time.
Outstanding shares of UBT Common Stock will be converted into the right to
receive that number of shares of Comerica Common Stock determined in accordance
with the Merger Agreement. See "Merger Consideration" above.
 
     As soon as is practicable after the Effective Time, Norwest Bank Minnesota,
N.A., or another person chosen by Comerica, in its capacity as Exchange Agent
(the "Exchange Agent"), will send to each UBT stockholder a form of letter of
transmittal (which will specify that delivery will be effected, and risk of loss
and title to certificates for shares of UBT Common Stock will pass, only upon
proper delivery of such certificates to the Exchange Agent) and instructions for
use in effecting the exchange of the certificates for shares of Comerica Common
Stock and cash in lieu of fractional shares.
 
                                       28
<PAGE>   36
 
     UBT STOCKHOLDERS SHOULD NOT FORWARD UBT CERTIFICATES TO THE EXCHANGE AGENT
UNTIL THEY HAVE RECEIVED TRANSMITTAL FORMS. UBT STOCKHOLDERS SHOULD NOT RETURN
STOCK CERTIFICATES WITH THE ENCLOSED FORMS OF PROXIES.
 
   
     Until the certificates representing UBT Common Stock are surrendered for
exchange after the consummation of the Merger, holders of such certificates will
not be paid dividends or other distributions that are declared on Comerica
Common Stock, or have the right to vote or exercise rights with respect to the
shares of Comerica Common Stock to which they will be entitled. Upon surrender
and exchange of such certificates, any such unpaid dividends or other
distributions will be paid (without interest) in accordance with the terms of
such Comerica Common Stock.
    
 
     No transfer taxes will be payable by any stockholder in respect of the
issuance of the new certificates, except that if any new certificate is to be
issued in a name other than that in which the UBT certificates surrendered shall
have been registered, it shall be a condition of such issuance that the holder
requesting such issuance shall properly endorse the certificate or certificates
and shall pay to Comerica or the Exchange Agent any transfer taxes payable on
the issuance, or on any prior transfer of such surrendered certificate, or
establish to the satisfaction of Comerica or the Exchange Agent that such taxes
have been paid or are not payable.
 
     Any Comerica Common Stock or cash delivered to the Exchange Agent (together
with any interest or profits earned thereon) and not distributed at the end of
nine months from the Effective Time, will be returned to Comerica, in which
event the persons entitled to payment shall look only to Comerica for
reimbursement. If any holder of UBT Common Stock shall be unable to surrender
such holder's certificates for such stock because such certificates have been
stolen, lost or destroyed, such holder may deliver in lieu thereof an affidavit
and indemnity bond in form and substance with surety reasonably satisfactory to
the Exchange Agent.
 
     After the Effective Time, there will be no further registration of
transfers on the stock transfer books of the surviving corporation of the shares
of UBT Common Stock which were outstanding immediately prior to the Effective
Time. If, after the Effective Time, certificates representing such shares are
presented to the surviving corporation in the Merger, they will be canceled and
exchanged for Comerica Common Stock as provided in the Merger Agreement.
 
     No fractional shares of Comerica Common Stock will be issued to any UBT
stockholder upon consummation of the Merger. In lieu of the issuance of any
fractional share of Comerica Common Stock, cash payments will be made to UBT
stockholders in respect of any fractional share in an amount equal to the
product (rounded to the nearest tenth) obtained by multiplying (a) $28.7083, by
(b) the fraction of the share of Comerica Common Stock to which the UBT
stockholder would otherwise be entitled. No such stockholder will be entitled to
dividends or other rights in respect of any such fraction. No interest on the
cash payments to be made in lieu of the issuance of fractional shares will
accrue pending surrender to the Exchange Agent of certificates representing UBT
Common Stock.
 
ACQUISITION PROPOSALS
 
     For the period between the execution of the Merger Agreement and the
Effective Time of the Merger, UBT has agreed not to authorize or knowingly
permit any of its representatives, directly or indirectly, to solicit or
encourage any Acquisition Proposal (as defined below), or participate in any
discussion or negotiations with any person or group of persons other than
Comerica, Interim or their representatives concerning any Acquisition Proposal.
 
     An "Acquisition Proposal" is defined as any (i) proposal pursuant to which
any person other than Comerica or Interim would acquire or participate in a
merger or other business combination involving UBT; (ii) proposal by which any
person or group other than Comerica or Interim would acquire the right to vote
10% or more of the capital stock of UBT entitled to vote thereon for the
election of directors; (iii) acquisition of the assets of UBT other than in the
ordinary course of business; or (iv) acquisition in excess of 10% of the
outstanding capital stock of UBT, other than that contemplated by the Merger
Agreement. However, UBT or its Board of Directors may not be prevented from (A)
furnishing non-public information to, or entering into discussions or
negotiations with, any person or entity in connection with an unsolicited bona
fide written
 
                                       29
<PAGE>   37
 
Acquisition Proposal by such person or entity or recommending an unsolicited
bona fide written Acquisition Proposal to the shareholders of UBT, if and only
to the extent that (1) the Board of Directors of UBT believes in good faith
(after consultation with and the concurrence of its financial advisor) that such
Acquisition Proposal would, if consummated, result in a transaction materially
more favorable to UBT's shareholders from a financial point of view than the
transaction contemplated by the Merger Agreement and the UBT Board of Directors
determined in good faith after consultation with its outside legal counsel that
such action is necessary for UBT to comply with its fiduciary duties to
shareholders under applicable law, and (2) prior to furnishing such non-public
information to, or entering into discussions or negotiations with, such person
or entity, the UBT Board of Directors received from such person or entity an
executed confidentiality agreement, with terms similar in scope to those
contained in the confidentiality agreement between Comerica and UBT, or (B)
complying with Rule 14e-2 promulgated under the Exchange Act of 1934, as
amended, with regard to an Acquisition Proposal. UBT is required to notify
Comerica immediately upon receipt of any such Acquisition Proposal.
 
CONDITIONS TO THE CONSUMMATION OF THE MERGER
 
   
     The obligations of Comerica, Interim and UBT under the Merger Agreement to
consummate the Merger are subject to various conditions, including but not
limited to, obtaining requisite stockholder and regulatory approvals; the
absence of any materially burdensome condition imposed in connection with
obtaining any such regulatory approvals; the absence of any action taken, or any
statute, rule, regulation or order enacted, entered, enforced or deemed
applicable to the Merger by any governmental entity which makes the Merger
illegal, requires any material divestiture or imposes a materially burdensome
condition; the accuracy in all material respects of the representations and
warranties of, and performance in all material respects of the covenants
required to be performed prior to the Effective Time by, the other parties to
the Merger Agreement; the absence of any materially adverse change to the other
parties to the Merger Agreement or their subsidiaries; receipt of opinion of
legal counsel to Comerica in respect of certain federal income tax consequences
of the Merger (see " -- Certain Federal Income Tax Consequences" below); receipt
of legal opinions and approval of their respective legal counsel of the validity
of the transactions contemplated in the Merger Agreement; and approval for
listing of the shares of the Comerica Common Stock to be issued in the Merger on
the NYSE and receipt of letters from each of Ernst & Young LLP and KPMG Peat
Marwick, LLP dated the effective date of the Registration Statement to be filed
in connection with the Merger and the Effective Time, in form and substance
satisfactory to Comerica and UBT and customary in scope and substance for
letters delivered by independent public accountants in connection with
registration statements similar to the Registration Statement.
    
 
     In addition, the obligations of Comerica and Interim under the Merger
Agreement to consummate the Merger are subject to certain other conditions,
including, but not limited to, the requirements that UBT's reserve for possible
loan losses on the Determination Date shall be at least the greater of
$4,700,000 or 2.25% of UBT's total loans outstanding on that date, and that
UBT's non-performing assets outstanding on the last day of the month immediately
preceding the Effective Time shall be no more than $4,711,431; the absence of
any materially adverse change to UBT or its subsidiaries; and receipt of
shareholder agreements from each UBT director who owns UBT Common Stock which,
among other things, obligates each such director to vote the shares of UBT
Common Stock owned or controlled by such director in favor of the Merger,
subject to fiduciary obligations. See "THE MERGER AGREEMENT -- Shareholder
Agreements."
 
     Further, the obligation of UBT under the Merger Agreement to consummate the
Merger is subject to certain conditions, including but not limited to the, the
receipt of a written opinion of Goldman Sachs concerning the fairness of the UBT
Conversion Rate.
 
     There can be no assurance that the conditions to the Merger will be
satisfied. See "THE MERGER AGREEMENT -- Conditions to the Merger."
 
     Under certain circumstances, the Merger Agreement may be terminated by
Comerica, Interim or UBT, as applicable, at any time prior to the Effective
Time, whether before or after approval of the Merger by the stockholders of UBT.
See "THE MERGER AGREEMENT -- Termination."

REGULATORY APPROVALS REQUIRED
 
     The Merger is subject to prior approval by the Board of Governors of the
Federal Reserve System (the "Federal Reserve Board") under Section 3 of the Bank
Holding Company Act of 1956, as amended (the "BHCA"). Although it is not a
condition of the Merger, Comerica may elect, after consummation of the Merger,
to merge the surviving corporation with and into Comerica Bank-California (the
"Subsidiary Bank Merger"). The Subsidiary Bank Merger (when and if it is
initiated) would be subject to prior approval by the Federal Deposit Insurance
Corporation (the "FDIC") under the Bank Merger Act, as amended (the "BMA").
Application for approval of the Merger under the BHCA has been filed with the
Federal Reserve Board. If the Subsidiary Bank Merger is initiated, an
application for its approval will be filed with the FDIC under the BMA. The BHCA
and the BMA prohibit the Federal Reserve Board and the FDIC from approving the
Merger or the Subsidiary Bank Merger, as the case may be, (i) if it would result
in a monopoly or be in furtherance of any combination or conspiracy to
monopolize or to attempt to monopolize the business of banking in any part of
the United States, or (ii) if its effect in any section of the country may be
substantially to lessen competition or to tend to create a monopoly, or if it
would in any other manner be in restraint of trade, unless the Federal Reserve
Board or the FDIC finds that the anticompetitive effects of the Merger or the
Subsidiary Bank Merger, as the case may be, are clearly outweighed in the public
interest by the probable effects of the transaction in meeting the needs and
convenience of the communities to be served. Neither the Merger nor the
Subsidiary Bank Merger may ordinarily be consummated until the thirtieth day
following the date of Federal Reserve Board and FDIC approval of each such
transaction, respectively, during which time the United States Department of
Justice may challenge the Merger or the Subsidiary Bank Merger, as the case may
be, on antitrust grounds. The commencement of an antitrust action would stay the
effectiveness of the Federal Reserve Board's approval unless a court
specifically orders otherwise. Under legislation enacted in September, 1994, the
post-approval waiting period may be shortened from 30 to 15 days, with the
consent of the Federal Reserve Board, as the case may be, and if the United
States Department of Justice does not object.
 
     It is possible that the Federal Reserve Board or the United States
Department of Justice may request that Comerica or UBT divest certain operations
in order to alleviate what such agency believes would otherwise be an adverse
competitive effect. Neither Comerica nor UBT can predict whether such
divestitures will be required, or if required, what the aggregate amount of any
such divestitures may be, but each believes that divestitures are unlikely to be
required, and if required, that the aggregate amount of any such divestitures
will not be material, on a pro forma basis, to the business, operations or
financial condition of the combined institution and its subsidiaries, taken as a
whole. The application to the Federal Reserve Board has not proposed any
divestiture. Any application to the FDIC relating to the Subsidiary Bank Merger
would not propose any divestiture. If the level of any required divestitures is
sufficiently large in amount so as to render the consummation of the Merger
inadvisable in the reasonable judgment of either the Comerica Board or the UBT
Board, one of the conditions to the consummation of the Merger will not be
satisfied and either Comerica or UBT may terminate the Merger Agreement. See
"THE MERGER AGREEMENT -- Conditions to the Merger" and -- "Termination" below.
 
     In addition, each of the BHCA and BMA require that the Federal Reserve
Board and the FDIC take into consideration, among other factors, the financial
and managerial resources and future prospects of the institutions and the
convenience and needs of the communities to be served. The Federal Reserve Board
and the FDIC have the authority to deny an application if it concludes that the
combined organization would have an inadequate capital position or if the
requirements of the Community Reinvestment Act of 1977 are not satisfied.
 
     While Comerica already conducts operations in California, its banking
operations are principally conducted in Michigan with operations in Ohio,
Illinois, Texas and Florida. Although Section 3(d) of the BHCA generally
restricts interstate bank acquisitions, there is an exception to this
restriction provided the relevant states authorize such acquisitions.
 
     The California Superintendent of Banks (the "California Superintendent")
must also approve the Merger, under provisions of California law that require
such approval in connection with the acquisition of a
 
                                       31
<PAGE>   39
 
   
California bank or bank holding company by an out-of-state bank holding company.
In order to approve the application, the California Superintendent must find (i)
that there is "substantial reciprocity" between the interstate banking laws of
the States of California and Michigan, meaning that a bank holding company whose
operations are principally conducted in California could acquire a Michigan bank
or bank holding company on terms and conditions that are substantially the same
as those on which a Michigan banking organization may acquire a California bank,
and (ii) that Comerica's acquisition of UBT will not have an adverse effect on
the public convenience or advantage in California. No assurances can be given
that the California Superintendent will approve the Merger, and the Merger will
not be consummated unless such approval is obtained. An application for this
approval under these provisions has been filed. In addition, the Subsidiary Bank
Merger would have to be reviewed by the California Superintendent for approval
under the California Banking Law.
    
 
     The Merger will require the approval of the Commissioner of the Michigan
Financial Institutions Bureau (the "Michigan Commissioner"). Before this
approval may be granted, Comerica must agree to comply with certain consumer
laws applicable to Michigan residents. In addition, the Michigan Commissioner
must assess the composite record of the bank subsidiaries of Comerica in meeting
the credit needs of the communities in the states in which these bank
subsidiaries are located, including low and moderate income neighborhoods,
consistent with the safe and sound operation of these bank subsidiaries. An
application for this approval under these provisions has been filed.
 
     The Merger and the Subsidiary Bank Merger (if and when it is initiated)
will not be consummated unless all of the requisite regulatory approvals for
such transactions are obtained. See "-- Conditions to Consummation of the
Merger" above and "THE MERGER AGREEMENT -- Amendment and Waiver" and "--
Termination" below.
 
     THERE CAN BE NO ASSURANCE THAT THE REGULATORY AUTHORITIES DESCRIBED ABOVE
WILL APPROVE THE MERGER AND THE SUBSIDIARY BANK MERGER (IF AND WHEN IT IS
INITIATED), AND IF SUCH TRANSACTIONS ARE APPROVED, THERE CAN BE NO ASSURANCE AS
TO THE DATE OF SUCH APPROVALS. THERE CAN ALSO BE NO ASSURANCE THAT ANY SUCH
APPROVALS WILL NOT CONTAIN A MATERIALLY BURDENSOME CONDITION OR REQUIREMENT
WHICH CAUSES SUCH APPROVALS TO FAIL TO SATISFY THE CONDITIONS TO CONSUMMATION OF
THE MERGER SET FORTH IN THE MERGER AGREEMENT. THERE CAN LIKEWISE BE NO ASSURANCE
THAT THE DEPARTMENT OF JUSTICE WILL NOT CHALLENGE THE MERGER OR THE SUBSIDIARY
BANK MERGER, OR IF SUCH A CHALLENGE IS MADE, AS TO THE RESULT THEREOF.
 
OPERATIONS PENDING THE MERGER
 
     In the Merger Agreement, UBT has agreed to carry on its business, and to
cause its subsidiaries to carry on their businesses in the ordinary course, in
substantially the manner as conducted prior to the execution of the Merger
Agreement and use commercially reasonable efforts to preserve intact its
business organizations, keep available the services of its officers and
employees and preserve its relationships with customers, suppliers and others
having business dealings with it, to notify Comerica promptly of any material
adverse changes or events, and maintain material permits, insurance and bonding
coverage, perform contractual obligations, observe legal requirements, and file
governmental reports and returns. In addition, UBT has agreed to maintain
assets, advise Comerica of certain acquisitions of its common stock, charge-off
loans consistent with past practice, maintain an adequate allowance for loan
losses and furnish certain reports and financial information and statements to
Comerica, maintain reserves for contingent liabilities, and furnish certain
information to Comerica with respect to litigation. UBT also agreed that it will
not take certain actions, including, by way of example and not of limitation,
declare or pay dividends other than regular quarterly cash dividends in an
amount not to exceed $.35 per share, issue capital stock (other than pursuant to
Stock Option Plans) or issue other securities convertible into capital stock,
acquire or dispose of material assets, incur indebtedness other than in the
ordinary course of business, make credit policies less stringent, make any
capital expenditures in excess of certain amounts, renew or enter into any new
employment agreements or terminate any employment benefit plan or arrangement,
except as contemplated by the Merger Agreement, or take any action that would
result in any of its representations and warranties in the Merger Agreement
becoming untrue or in any condition to the Merger not being satisfied, or amend
its Articles of Incorporation or Bylaws. See "THE MERGER AGREEMENT -- Conduct of
Business Pending the Merger."
 
                                       32
<PAGE>   40
 
OPERATIONS AFTER THE MERGER
 
     If the Merger is consummated at the Effective Time, UBT will be the
surviving corporation with the Articles of Incorporation of UBT and the name
University Bank & Trust Company. The separate existence of Interim will cease.
It is anticipated that upon consummation of the Merger, Comerica will transfer
the stock of the surviving corporation to Comerica California Incorporated. It
is also anticipated that subsequent to consummation of the Merger, the surviving
corporation will merge into Comerica Bank-California. At that time, it is
expected that the surviving corporation will be run as a separate division of
Comerica Bank-California. At the Effective Time, the Board of Directors and
officers of the surviving corporation will be made up of certain directors of
Interim and UBT serving in those capacities at the Effective Time.
 
     Following the consummation of the Merger, Carl J. Schmitt is expected to
remain as Chairman of the Board of the surviving corporation. It is also
expected that Mr. Schmitt, upon the anticipated Merger of the surviving
corporation into Comerica Bank-California, will become a member of the Board of
Directors of Comerica Bank-California and, as a result, will receive a fee for
each board meeting he attends as well as reimbursement for expenses he incurs in
doing so. See "THE MERGER -- Interests of Certain Persons in the Merger."
 
     Banking policies and procedures of the surviving corporation and its
subsidiaries will continue in accordance with the policies of Comerica.
 
     It is part of Comerica's current business strategy to expand its business
activities into states such as California where management believes there are
long-term opportunities which will benefit Comerica and its stockholders. In
California, Comerica has a wholly-owned bank holding company subsidiary which
owns and operates Comerica Bank-California See "THE COMPANIES -- Comerica
Incorporated -- General."
 
     Information about the directors, executive officers and principal
shareholders of Comerica is contained in Comerica's Proxy Statement for its 1994
Annual Meeting of Shareholders, relevant portions of which are incorporated by
reference in this Proxy Statement/Prospectus pursuant to Comerica's Annual
Report on Form 10-K for the year ended December 31, 1993. See "INCORPORATION OF
CERTAIN DOCUMENTS BY REFERENCE" and "AVAILABLE INFORMATION."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     Certain members of the management and Board of Directors of UBT have
certain interests in the Merger that are in addition to their general interests
as stockholders of UBT. The UBT Board was aware of these interests and
considered them, among other matters, in approving the Merger Agreement and the
transactions contemplated thereby.
 
   
     The Merger Agreement provides, as a condition to Comerica's obligations to
consummate the Merger, that Carl J. Schmitt shall have entered into a
Non-Competition Agreement with Comerica pursuant to which, among other things,
Mr. Schmitt will agree not to solicit, cause or induce any employee of UBT to
leave; cause any customer or client of UBT to terminate or adversely change any
relationship with UBT; cause, induce or encourage any potential supplier or
customer to not enter into any business relationship with UBT or directly or
indirectly as, among other things, an employee or director, engage in any
business relating to a bank or other financial institution in the counties of
Santa Clara and Santa Cruz in the State of California. The Non-Competition
Agreement has a term of five years from the date of Mr. Schmitt's termination of
employment with UBT. Mr. Schmitt will receive the sum of approximately $1.2
million within 10 days of the execution of the Non-Competition Agreement to be
executed at the consummation of the Merger. In addition, upon closing of the
Merger, Mr. Schmitt will receive a one time severence payment of $1 million.
    
 
     As did each of the other director-shareholders of UBT, Carl J. Schmitt has
entered into a Shareholder Agreement with Comerica. See "THE MERGER AGREEMENT --
Shareholder Agreements." In addition, each of Carl J. Schmitt, Gayle A.
Anderson, David Hood, Hall Palmer and Suzanne M. Powers has entered into an
Affiliate's Agreement with Comerica. See "THE MERGER AGREEMENT -- Resales by
Affiliates."
 
                                       33
<PAGE>   41
 
     UBT has agreements with each of its directors, under which UBT will
indemnify each of such persons, to the maximum amount permitted by law, for
certain liabilities incurred by such persons in their capacities as directors of
UBT. Comerica has agreed that all rights of indemnification under such
agreements and UBT's Charter and Bylaws shall survive the Merger and continue in
full force and effect, without any amendment thereto, for a period of six years
from the Effective Date.
 
     Under the Merger Agreement, Comerica has agreed to use its commercially
reasonable efforts to cause to be maintained in effect, for a period of six
years after the Effective Time, policies of directors' and officers' liability
insurance (with such coverage, terms and conditions as are now less advantageous
than the insurance presently maintained by Comerica for its officers and
directors) with respect to all matters arising from facts or events which
occurred before the Effective Time for which UBT, or its subsidiaries would have
had an obligation to indemnify their directors and officers. Comerica's
obligation to do so, however, is limited to the extent that it need not pay
premiums in excess of 300% of the amount of the 1994 annual premiums paid by UBT
for such insurance.
 
     As of September 30, 1994, the directors and executive officers of UBT
beneficially owned 230,551 shares of UBT Common Stock, representing
approximately 16.5% of UBT Common Stock outstanding at that time. See "THE
SPECIAL MEETING -- Security Ownership of Certain Beneficial Owners."
 
     Comerica has indicated that it does not intend to employ Gayle A. Anderson,
Executive Vice President and Chief Financial Officer of UBT, subsequent to the
consummation of the Merger and that in connection with her departure she will be
provided with a one-time cash severance payment of approximately $380,000.
 
STOCK OPTION PLANS
 
     UBT has two stock option plans, the Amended and Restated Stock Option Plan
(the "Option Plan") and the Outside Directors Stock Option Plan (the "Directors
Plan"). Options granted under both the Option Plan and the Directors Plan
generally vest (i.e., become exercisable) at the rate of 20% each year from the
date of grant.
 
   
     The table below shows, as to the executive officers and directors named,
the aggregate amount of UBT Common Stock subject to options outstanding at
September 30, 1994 under the Option Plan and the Directors Plan. All options
under the Option Plan and the Directors Plan, whether vested or unvested, will
be converted into rights with respect to Comerica Common Stock and Comerica
shall assume each such stock option in accordance with the Option Plan and the
Directors Plan, respectively. See "THE MERGER -- Merger Consideration."

CANCELLATION FEE; LIQUIDATED DAMAGES
 
     The Merger Agreement provides that, in the event an Acquisition Event shall
occur or (i) any of UBT, Comerica or Interim terminates the Merger Agreement
because the Subsidiary Merger Agreement and the Merger are not ratified and
approved by UBT's shareholders, (ii) any of UBT, Comerica or Interim terminates
the Merger Agreement because there shall have been a material breach of any of
the representations or warranties set forth in the Merger Agreement on the part
of the other party, (iii) Comerica terminates the Merger Agreement because there
is a default by UBT, pursuant to the Merger Agreement and the continuance of
such failure for a period of 20 business days after written notice, which
failure to perform, in the reasonable opinion of Comerica and Interim cannot be
cured prior to the closing, or (iv) Comerica terminates the Agreement because
the UBT Board did not publicly recommend in this Proxy Statement/Prospectus that
UBT stockholders adopt and approve the Merger Agreement or the UBT Board shall
withdraw, modify or amend such recommendation in any respect materially adverse
to Comerica, followed in the case of each of the foregoing clauses (i) through
(iv) above by an Acquisition Event within 90 days of such termination, UBT is
required to pay to Comerica the sum of $3,200,000 as reasonable and full
liquidated damages and reasonable compensation for the loss sustained thereby.
 
     In the event of termination by UBT of the Merger Agreement because Interim
or Comerica has breached any of their representations and warranties set forth
in the Merger Agreement and in the reasonable opinion of UBT such breach cannot
be cured prior to closing and would have a Material Adverse Effect on Interim or
Comerica, or because of a default by Comerica or Interim pursuant to the Merger
Agreement and the continuance of such failure for a period of 20 business days
after written notice of such default, in the reasonable opinion of UBT, cannot
be cured prior to the closing, then Comerica and Interim, jointly and severally,
shall pay to UBT as reasonable and full liquidated damages and reasonable
compensation for the loss sustained thereby and not as a penalty or forfeiture,
the sum of $2,000,000. The making and receipt of such payments, as applicable
shall satisfy the obligations and liabilities of UBT and Comerica and Interim,
respectively under the Merger Agreement, and UBT, Comerica and Interim, as the
case may be, shall have no further obligations of any kind under the Merger
Agreement. See "THE MERGER AGREEMENT -- Cancellation Fee; Liquidated Damages."
 
ANTICIPATED ACCOUNTING TREATMENT
 
     The Merger is expected to qualify as a purchase for accounting and
financial reporting purposes. Under this method of accounting, Comerica will
adjust the assets and liabilities of UBT to their fair values as of the
Effective Time. The shares of Comerica Common Stock to be issued in the Merger
will be authorized but unissued shares, or shares held as treasury shares.
Subject to the rules of the Commission, Comerica may repurchase shares of
Comerica Common Stock in open market or other transactions to fund the Merger
consideration.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     Required Tax Opinion Regarding the Merger. The obligations of Comerica and
UBT to effect the Merger are conditioned upon the receipt of an opinion of legal
counsel satisfactory to Comerica subject to assumptions and exceptions normally
included, dated the Effective Time, to the effect that the Merger will be
treated for federal income tax purposes as a reorganization within the meaning
of Sections 368(a)(1)(A) and 368(a)(2)(E) of the Internal Revenue Code of 1986,
as amended (the "IRC"), and that Comerica, Interim and UBT will each be a party
to that reorganization within the meaning of Section 368(b) of the IRC. It is
expected that Miller, Canfield, Paddock and Stone, P.L.C., counsel to Comerica,
will deliver such an opinion to Comerica and UBT.
 
     Summary of Anticipated Federal Income Tax Consequences. The following is a
summary of the anticipated Federal income tax consequences of the Merger to UBT
stockholders. It is not intended as tax advice and is based upon the parties'
understanding of the Federal income tax laws as currently interpreted and does
not address issues of state or local taxation. It does not constitute a
representation by UBT, Interim,
 
                                       35
<PAGE>   43
 
Comerica, or their counsel. The following discussion is included solely for
purposes of general information only.
 
     BECAUSE OF THE COMPLEXITIES OF FEDERAL, STATE, AND LOCAL INCOME TAX LAWS,
IT IS RECOMMENDED THAT UBT STOCKHOLDERS CONSULT THEIR OWN TAX ADVISORS
CONCERNING THE FEDERAL, STATE AND LOCAL TAX CONSEQUENCES OF THE MERGER.
 
     This summary is limited to those persons who hold shares of UBT Common
Stock as "capital assets" (generally, property held for investment) within the
meaning of Section 1221 of the IRC. (Any reference herein to a "Section" is a
reference to a section of the IRC unless otherwise specified.) The tax
consequences to any particular stockholder of UBT Common Stock may be affected
by matters not discussed below. For example, certain taxpayers, such as life
insurance companies, tax-exempt organizations, and foreign taxpayers may be
subject to special rules not addressed herein. In addition, the tax consequences
to UBT stockholders who acquired their shares of UBT Common Stock pursuant to
the exercise of employee stock options or otherwise as compensation is not
discussed below.
 
     Assuming the Merger satisfies all requirements of Section 368(a)(1)(A) and
Section 368(a)(2)(E), the Merger will have the Federal income tax consequences
described below.
 
     Receipt Solely of Comerica Common Stock in Exchange for UBT Common Stock. A
stockholder who receives solely shares of Comerica Common Stock in exchange for
shares of UBT Common Stock in the Merger will not recognize gain or loss on the
exchange. The stockholder's tax basis in the Comerica Common Stock received will
be the same as the stockholder's tax basis in the shares of UBT Common Stock
exchanged in the Merger, and the holding period of the Comerica Common Stock
received will include the holding period of the UBT Common Stock exchanged.
 
     Receipt of Cash in Lieu of Fractional Shares. Pursuant to the Merger, UBT
stockholders will receive cash in lieu of fractional shares of Comerica Common
Stock. Since the payment to a stockholder of cash in lieu of a fractional
Comerica share in this transaction is undertaken solely for the purpose of
saving the expense and inconvenience of issuing and transferring fractional
shares, and is not separately bargained for consideration, these payments will
generally be treated as having been received as distributions in full payment in
exchange for the Comerica Common Stock redeemed as provided in Section 302(a)
and taxed as capital gain or loss.
 
RESALE OF COMERICA COMMON STOCK; RESTRICTIONS ON TRANSFER
 
     The shares of Comerica Common Stock to be issued in the Merger will be
registered under the Securities Act and will be freely transferable under the
Securities Act, except for shares issued to any stockholder who may be deemed to
be an "affiliate" of UBT for purposes of Rule 145 under the Securities Act.
Affiliates may not sell their shares of Comerica Common Stock acquired in
connection with the Merger except pursuant to an effective registration
statement under the Securities Act covering such shares or in compliance with
Rule 145 or another applicable exemption from the registration requirements of
the Securities Act. Persons who may be deemed to be affiliates of UBT generally
include individuals or entities that control, are controlled by or under common
control with UBT, and may include certain officers and directors of UBT, as well
as principal stockholders of UBT.
 
   
     UBT has delivered to Comerica a written agreement from each person UBT
believes to be an affiliate of UBT obligating each such person to ensure
compliance with the Securities Act. See "THE MERGER AGREEMENT -- Resales by
Affiliates".
    
 
STOCK EXCHANGE LISTING
 
     The Comerica Common Stock is listed on the NYSE. Comerica has agreed to
apply for NYSE listing of the shares of Comerica Common Stock to be issued in
the Merger. The obligations of the parties to the Merger Agreement to consummate
the Merger are subject to approval of that application and the listing by the
NYSE of such shares. See "THE MERGER -- Conditions to the Consummation of the
Merger" above.
 
                                       36

DISSENTER'S RIGHTS
 
     The stockholders of UBT may have certain dissenter's rights under Chapter
13 (Sections 1300-1312) of the California General Corporations Law (the "CGCL")
if said stockholders qualify as holders of "dissenting shares" under the CGCL.
The exercise of dissenter's rights may require UBT to purchase for cash at fair
market value from dissenting UBT stockholders UBT Common Stock which qualifies
as dissenting shares. The fair market value will be determined as of October 3,
1994, the day before the first announcement of the terms of the Merger; provided
however, that fair market value will not be adjusted for any appreciation or
depreciation in value resulting from the Merger.
 
     "Dissenting Shares" are defined under the CGCL as 1) any shares not listed
on a national securities exchange certified by the California Commissioner of
Corporations or listed on the list of OTC margin stocks issued by the Board of
Governors of the Federal Reserve System immediately prior to a reorganization
("Listed Securities"), 2) Listed Securities, if demands for payment are filed
with respect to 5% or more of the outstanding shares of that class of Listed
Securities; 3) shares which were outstanding on the date for determination of
stockholders entitled to vote on the reorganization and were not voted in favor
of the reorganization, or shares described in 1) above which were voted against
the reorganization; 4) shares which the dissenting stockholder has demanded that
the corporation purchase at fair market value in accordance with the CGCL; and
5) shares which the dissenting stockholder has submitted for endorsement in
accordance with the CGCL. Under the CGCL, UBT stockholders will waive their
stockholder dissenting rights if they do not vote against the Merger.
 
   
     Inasmuch as the UBT Common Stock is admitted for quotation on the
NASDAQ/National Market System, a national securities exchange certified by the
California Commissioner of Corporations, shares of UBT Common Stock will only
qualify as Dissenting Shares if demands for payment are filed with respect to 5%
or more of the outstanding shares of UBT Common Stock. Subject to this
limitation, holders of UBT Common Stock desiring to exercise dissenter's rights
must comply with the requirements set forth in items 4 and 5 listed above.
    
 
     Assuming the Merger Proposal is approved, UBT must mail to all of its
stockholders meeting those requirements notice of such approval of the
reorganization within 10 days of the Special Meeting, together with a copy of
the relevant sections of the CGCL, a statement of the price determined by UBT to
represent the fair market value of the Dissenting Shares, and a brief
description of the procedure to be followed if a stockholder desires to exercise
dissenter's rights. The statement of price constitutes an offer by UBT to
purchase the shares of the dissenting stockholder at such price, unless those
shares lose their status as Dissenting Shares under the CGCL.
 
     Merely voting or delivering a proxy directing a vote against the approval
of the Merger, or failing to deliver a proxy or vote as to approval of the
Merger, does not constitute a demand for purchase. A written demand is
essential. Any stockholder of record who has the right to require UBT to
purchase such stockholders' shares of UBT Common Stock and has complied with the
requirements set forth in items 4 and 5 listed above, and who desires that UBT
purchase such shares of UBT Common Stock, shall make written demand upon UBT for
the purchase of such shares of UBT Common Stock and payment to the stockholder
in cash of their fair market value. Notice must be received by UBT or any
transfer agent thereof, not later than the date of the Special Meeting. The
demand must state the number and class of shares of UBT Common Stock held of
record by the stockholder which the stockholder demands that UBT purchase and
shall contain a statement of what such stockholder claims to be the fair market
value of those shares as of the day before the announcement of the Merger. The
statement of fair market value constitutes an offer by the stockholder to sell
the shares at such price. A stockholder may not withdraw a demand for payment
without the consent of UBT.
 
     Holders of UBT common Stock desiring to exercise dissenter's rights should
send demand for payment to UBT in care of Gayle A. Anderson, Secretary, 250
Lytton Avenue, P.O. Box 89, Palo Alto, California 94301 by registered or
certified mail, return receipt requested. The demand should be signed by the
stockholder of record (or his or her duly authorized representative) exactly as
his or her name appears on the certificates evidencing ownership of the shares
of UBT Common Stock. A demand for the purchase of shares of UBT
 
                                       37
<PAGE>   45
 
Common Stock owned jointly by more than one person should identify and be signed
by all such holders. Any person signing a demand for purchase in any
representative capacity (such as attorney-in-fact, executor, administrator,
trustee or guardian) should indicate his or her title and, if UBT so requests,
furnish written proof of his or her capacity and authority to sign the demand.
 
   
     Within 30 days after the date notice of approval of the Merger is mailed to
its stockholders by UBT, any stockholder exercising dissenter's rights must
deliver to UBT at its principal office or at the office of any transfer agent
thereof, the share certificates representing the shares of UBT Common Stock the
stockholder demands to be purchased, to be stamped or endorsed with the
statement that the shares are Dissenting Shares or to be exchanged for
certificates of appropriate denomination so stamped or endorsed. Upon subsequent
transfer of the Dissenting Shares on the corporate books, the new certificate,
initial transaction statement, and other written statements issued thereof shall
bear a like statement, together with the name of the original dissenting holder
of the shares.
    
 
     If UBT and a dissenting stockholder agree that the shares are Dissenting
Shares and agree upon the price of the shares, the stockholder will be entitled
to that price plus interest at the legal rate on judgments from the date of the
agreement. The agreement fixing the fair market value of any Dissenting Shares
must be filed with the Secretary of UBT. Subject to certain creditors' rights,
UBT shall make payment at the later of 1) within 30 days after the agreement or
2) within 30 days after any statutory or contractual conditions to the Merger
are satisfied, subject to surrender of the share certificates to UBT. Cash
dividends, if any, declared and paid by UBT on the Dissenting Shares after the
date of approval of the Merger and prior to payment for the Dissenting Shares
shall be credited against the total amount to be paid by UBT.
 
     If UBT and a dissenting stockholder disagree that the shares are Dissenting
Shares and/or disagree on the fair market value of the shares, the stockholder
may file within 6 months after the date on which the notice of the approval of
the Merger by the outstanding shares was mailed to the stockholder, a complaint
in the Superior Court for Santa Clara County requesting that the court determine
whether the shares are Dissenting Shares and/or the fair market value of the
shares. In addition, any other dissenting stockholder may intervene in any
action pending on such a complaint.
 
     If the status of the shares is at issue, the court will first determine
whether the shares are Dissenting Shares. If the court finds that the shares are
Dissenting Shares, the court, or one or more impartial appraisers, will at that
time determine the fair market value of the shares if said amount also is in
issue. If judgement is rendered against UBT, UBT will pay the amount equal to
the fair market value of each Dissenting Share multiplied by the number of
Dissenting Shares which any dissenting stockholder is entitled to require UBT to
purchase, with interest thereon at the legal rate from the date judgment was
entered. Judgement is payable upon the endorsement and delivery to UBT of the
certificates of the shares described in the judgement. Costs of the action will
be assessed or apportioned as the court considers equitable, but, if the
appraisal exceeds the price offered by UBT, UBT will be assessed all costs
(including, in the discretion of the court, attorneys' fees, fees of expert
witnesses and interest at the legal rate from the date of compliance with UBT's
obligations under Chapter 13 of the CGCL if the value for the Dissenting Shares
is more than 125% of the price originally offered by UBT).
 
     No stockholder of UBT who has a right to demand payment of cash for the
shares of UBT Common Stock held by him or her shall have any right at law or in
equity to attack the validity of the Merger or to have the Merger set aside or
rescinded, except in an action to test whether the number or shares required to
authorize or approve the Merger have been legally voted in favor thereof.
 
     UBT Common Stock holders wishing to exercise dissenter's rights should seek
advice from their attorney in conjunction with the exercise of such rights.

                       CERTAIN REGULATORY CONSIDERATIONS
 
GENERAL
 
     Bank holding companies and banks are extensively regulated under both
federal and state law. To the extent that the following information describes
statutory and regulatory provisions, it is qualified in its entirety by
reference to the particular statutory and regulatory provisions. A change in
applicable law or regulation may have a material effect on the business of
Comerica.
 
     As a bank holding company, Comerica is subject to regulation under the BHCA
and its examination and reporting requirements. Under the BHCA, bank holding
companies may not (subject to certain limited exceptions) directly or indirectly
acquire the ownership or control of more than 5% of any class of voting shares
or substantially all of the assets of any company, including a bank, without the
prior written approval of the Federal Reserve Board. In addition, banking
holding companies are generally prohibited under the BHCA from engaging in
nonbanking activities, subject to certain exceptions.
 
     The BHCA prohibits the Federal Reserve Board from approving the acquisition
by a bank holding company of more than 5% of any class of the voting shares of,
or substantially all the assets of, any bank (or its holding company) located
outside of the state in which the operations of such acquiring bank holding
company's banking subsidiaries are principally conducted on the date such
company became a bank holding company unless such acquisition is specifically
authorized by the laws of the state in which the bank to be acquired is located.
Most states, including Michigan and California, have adopted legislation that
permits out-of-state bank holding companies throughout the United States to
acquire local banks and bank holding companies. Most states that have enacted
such nationwide interstate banking laws, including Michigan and California, have
a reciprocity requirement. In approving Comerica's acquisition of the
predecessors to Comerica Bank -- California, both the Federal Reserve Board and
the California Superintendent determined that the "substantial reciprocity"
requirement of California law was met in connection with such an interstate
acquisition.
 
INTERSTATE BANKING AND BRANCHING
 
     On September 29, 1994, the Reigle/Neal Interstate Banking and Branching
Efficiency Act of 1994 (the "Interstate Act") was signed into law. This
Interstate Act effectively permits nationwide banking. The Interstate Act
provides that one year after enactment, adequately capitalized and adequately
managed bank holding companies may acquire banks in any state, even in those
jurisdictions that currently bar acquisitions by out-of-state institutions,
subject to deposit concentration limits. The deposit concentration limits
provide that regulatory approval by the Federal Reserve Board may not be granted
for a proposed interstate acquisition if after the acquisition, the acquiror on
a consolidated basis would control more than 10% of the total deposits
nationwide or would control more than 30% of deposits in the state where the
acquiring institution is located. The deposit concentration state limit does not
apply for initial acquisitions in a state and in every case, may be waived by
the state regulatory authority. Interstate acquisitions are subject to
compliance with the Community Reinvestment Act ("CRA"). States are permitted to
impose age requirements not to exceed five years on target banks for interstate
acquisitions. States are not allowed to opt-out of interstate banking.
 
     Branching between states may be accomplished either by merging separate
banks located in different states into one legal entity, or by establishing de
novo branches in another state. Consolidation of banks is not permitted until
June 1, 1997 provided that the state has not passed legislation "opting-out" of
interstate branching. If a state opts-out prior to June 1, 1997, then banks
located in that state may not participate in interstate branching. A state may
opt-in to interstate branching by bank consolidation or by de novo branching by
passing appropriate legislation earlier than June 1, 1997. Interstate branching
is also subject to a 30% statewide deposit concentration limit on a consolidated
basis, and a 10% nationwide deposit concentration limit. The laws of the host
state regarding community reinvestment, fair lending, consumer protection
(including usury limits) and establishment of branches shall apply to the
interstate branches.
 
     De novo branching by an out-of-state bank is not permitted unless the host
state expressly permits de novo branching by banks from out-of-state. The
establishment of an initial de novo branch in a state is subject
 
                                       39
<PAGE>   47
 
to the same conditions as apply to initial acquisition of a bank in the host
state other than the deposit concentration limits.
 
     Effective one year after enactment, the Interstate Act permits bank
subsidiaries of a bank holding company to act as agents for affiliated
depository institutions in receiving deposits, renewing time deposits, closing
loans, servicing loans and receiving payments on loans and other obligations. A
bank acting as agent for an affiliate shall not be considered a branch of the
affiliate. Any agency relationship between affiliates must be on terms that are
consistent with safe and sound banking practices. The authority for an agency
relationship for receiving deposits includes the taking of deposits for an
existing account but is not meant to include the opening or origination of new
deposit accounts. Subject to certain conditions, insured saving associations
which were affiliated with banks as of June 1, 1994, may act as agents for such
banks. An affiliate bank or saving association may not conduct any activity as
an agent which such institution is prohibited from conducting as principal.
 
     If an interstate bank decides to close a branch located in a low- or
moderate-income area, it must comply with additional branch closing notice
requirements. The appropriate regulatory agency is authorized to consult with
community organizations to explore options to maintain banking services in the
affected community where the branch is to be closed.
 
     To ensure that interstate branching does not result in taking deposits
without regard to a community's credit needs, the regulatory agencies are
directed to implement regulations prohibiting interstate branches from being
used as "deposit production offices." The regulations to implement its
provisions are due by June 1, 1997. The regulations must include a provision to
the effect that if loans made by an interstate branch are less than fifty
percent of the average of all depository institutions in the state, then the
regulator must review the loan portfolio of the branch. If the regulator
determines that the branch is not meeting the credit needs of the community, it
has the authority to close the branch and to prohibit the bank from opening new
branches in that state.
 
     When the interstate banking provisions become effective in one year,
Comerica will have enhanced opportunities to acquire banks in any state subject
to approval by the appropriate federal and state regulatory agencies. When the
interstate branching provisions become effective in June 1997, Comerica will
have the opportunity to consolidate its affiliate banks to create one legal
entity with branches in more than one state should management decide to do so,
or to establish branches in different states, subject to any state opt-out
provisions. The agency authority permitting Comerica affiliate banks to act as
agents for each other in accepting deposits or servicing loans should make it
more convenient for customers of one Comerica bank to transact their banking
business at a Comerica affiliate in another state provided that operations are
in place to facilitate these out of state transactions.
 
PAYMENT OF DIVIDENDS
 
     Comerica is a legal entity separate and distinct from its banking and other
subsidiaries. Most of Comerica's revenues result from dividends paid to it by
its bank subsidiaries. There are statutory and regulatory requirements
applicable to the payment of dividends by subsidiary banks as well as by
Comerica to its shareholders.
 
     Each state bank subsidiary that is a member of the Federal Reserve System
and each national banking association is required by federal law to obtain the
prior approval of the Federal Reserve Board or the Comptroller of the Currency
(the "Comptroller"), as the case may be, for the declaration and payment of
dividends if the total of all dividends declared by the board of directors of
such bank in any year will exceed the total of (i) such bank's net profits (as
defined and interpreted by regulation) for that year plus (ii) the retained net
profits (as defined and interpreted by regulation) for the preceding two years,
less any required transfers to surplus. In addition, these banks may only pay
dividends to the extent that retained net profits (including the portion
transferred to surplus) exceed bad debts (as defined by regulation).
 
     Under the foregoing dividend restrictions, in 1994 Comerica's subsidiary
banks, without obtaining governmental approvals, can declare aggregate dividends
of approximately $273 million from retained net
 
                                       40
<PAGE>   48
 
profits of the preceding two years, plus an amount approximately equal to the
net profits (as measured under current regulations), if any, earned for the
period from January 1, 1994 through the date of declaration. During 1993,
Comerica's subsidiary banks paid $311 million in dividends.
 
     The banking authorities in the states where Comerica owns state-chartered
banks also regulate the payment of dividends by banks organized in such states.
Generally, (i) California state banks such as Comerica Bank-California may not
declare or pay a dividend, without the prior written approval of the California
Superintendent, if the total of all dividends declared by such bank in any
calendar year would exceed the total of its net profits, as defined, for that
year combined with its retained net profits, as defined, for the preceding two
years, (ii) Michigan state banks such as Comerica Bank may not pay a dividend if
the amount of such dividend would exceed net profits then on hand or surplus
remaining after payment thereof would be less than 20 percent of the bank's
capital, and (iii) payment of dividends by Texas state banks such as Comerica
Bank-Texas are restricted by minimum capital requirements. Generally, an
Illinois state chartered bank, such as Comerica Bank-Illinois, may pay dividends
only out of net profits. If an Illinois bank's surplus does not equal its
capital, it may declare a dividend only after at least one-tenth of its net
profits since the declaration of the last dividend has been added to its
surplus. An Illinois bank may not pay dividends in an amount greater than net
profits then on hand, less deductions for losses and bad debts, as defined by
statute.
 
     The payment of dividends by Comerica and its bank subsidiaries is also
affected by various regulatory requirements and policies, such as the
requirement to maintain capital at or above regulatory guidelines. In addition,
if, in the opinion of the applicable regulatory authority, a bank under its
jurisdiction is engaged in or is about to engage in an unsafe or unsound
practice (which, depending on the financial condition of the bank, could include
the payment of dividends), such authority may require, after notice and hearing,
that such bank cease and desist from such practice. The Federal Reserve Board
and the Comptroller have each indicated that paying dividends that deplete a
bank's capital base to an inadequate level would be an unsafe and unsound
banking practice. The Federal Reserve Board, the Comptroller and the FDIC have
issued policy statements which provide that bank holding companies and insured
banks should generally only pay dividends out of current operating earnings.
 
CERTAIN TRANSACTIONS BY COMERICA WITH ITS AFFILIATES
 
     There are also various legal restrictions on the extent to which Comerica
and most of its nondepository subsidiaries can borrow or otherwise obtain credit
from, or engage in certain other transactions with, its depository subsidiaries.
The "covered transactions" that an insured depository institution and its
subsidiaries are permitted to engage in with their nondepository affiliates are
limited to the following amounts: (i) in the case of any one such affiliate, the
aggregate amount of covered transactions of the insured depository institution
and its subsidiaries cannot exceed 10% of the capital stock and the surplus of
the insured depository institution; and (ii) in the case of all affiliates, the
aggregate amount of covered transactions of the insured depository institution
and its subsidiaries cannot exceed 20% of the capital stock and surplus of the
insured depository institution. In addition, extensions of credit that
constitute covered transactions must be collateralized in prescribed amounts.
 
     "Covered transactions" are defined by statute to include a loan or
extension of credit to the affiliate, a purchase of securities issued by an
affiliate, a purchase of assets from the affiliate (unless otherwise exempted by
the Federal Reserve Board), the acceptance of securities issued by the affiliate
as collateral for a loan and the issuance of a guarantee, acceptance, or letter
of credit for the benefit of an affiliate. Further, a bank holding company and
its subsidiaries are prohibited from engaging in certain tie-in arrangements in
connection with any extension of credit, lease or sale of property or furnishing
of services.
 
CAPITAL
 
     The Federal Reserve Board has adopted final risk based capital guidelines
for bank holding companies. The minimum guideline for the ratio of total capital
("Total Capital") to risk weighted assets (including certain off-balance-sheet
activities, such as standby letters of credit) is 8%. At least half of the Total
Capital is to be composed of common stockholders' equity, minority interests in
the equity accounts of consolidated
 
                                       41
<PAGE>   49
 
subsidiaries and a limited amount of perpetual preferred stock, less disallowed
intangibles including goodwill ("Tier 1 Capital"). The remainder may consist of
subordinated debt, other preferred stock and a limited amount of loan loss
reserves ("Tier 2 Capital").
 
     In addition, the Federal Reserve Board has established minimum leverage
ratio guidelines for bank holding companies. These guidelines provide for a
minimum Tier 1 Capital leverage ratio (Tier 1 Capital to total assets, less
goodwill) of 3% for bank holding companies that meet certain specified criteria,
including having the highest regulatory rating. All other bank holding companies
will generally be required to maintain a minimum Tier 1 Capital leverage ratio
of 3% plus an additional cushion of 100 to 200 basis points. The Federal Reserve
Board has not advised Comerica of any specific minimum Tier 1 Capital leverage
ratio applicable to it. The guidelines also provide that bank holding companies
experiencing internal growth or making acquisitions will be expected to maintain
strong capital positions substantially above the minimum supervisory levels
without significant reliance on intangible assets (e.g., goodwill, core deposit
intangibles and purchased mortgage servicing rights). Furthermore, the
guidelines indicate that the Federal Reserve Board will continue to consider a
"tangible Tier 1 Capital leverage ratio" (deducting all intangibles) in
evaluating proposals for expansion or new activities. As of September 30, 1994,
the "tangible Tier 1 Capital leverage ratios" of Comerica, UBT and pro forma
(giving effect to the Merger) for UBT and Comerica combined were 6.89%, 7.91%
and 6.79%, respectively.
 
     The following tables set forth the Tier 1 capital to risk-weighted assets
ratios, the total capital to risk-weighted assets ratios and the Tier 1 leverage
ratios for Comerica and UBT individually and on a pro forma combined basis as of
certain dates and periods. Such pro forma combined data is derived from the
financial information of Comerica and UBT at September 30, 1994 and for each of
the years presented below and gives effect to the Merger, the repurchase of
shares to be issued to holders of UBT Common Stock as consideration for the
Merger, adjustment to fair value of the assets and liabilities of UBT as of the
Effective Time.

</TABLE>
 
     Each of Comerica's banks is subject to similar capital requirements adopted
by the Federal Reserve Board, the Comptroller or the FDIC. At September 30,
1994, each of Comerica's subsidiary banks had a Tier 1 Capital ratio and a Total
Capital ratio (computed under the 1993 guidelines) in excess of the fully phased
in requirements and a Tier 1 Capital leverage ratio in excess of 6.50%. At
September 30, 1994, Comerica Bank's Tier 1 Capital ratio and Total Capital ratio
(computed under the 1993 guidelines) was in excess of the fully phased in
requirements and its Tier 1 Capital leverage ratio was 6.49%. No regulatory
agency has advised any of Comerica's subsidiary banks of any specific applicable
minimum Tier 1 Capital leverage ratio.
 
     Failure to meet capital guidelines could subject an insured bank to a
variety of enforcement remedies, including the termination of deposit insurance
by the FDIC and a prohibition on the taking of brokered deposits. See "FDICIA"
below.
 
     It is possible that bank regulators will raise capital requirements
applicable to banking organizations beyond their current levels. However, the
management of Comerica is unable to predict whether and when higher capital
requirements might be imposed and, if they are imposed, at what levels and on
what schedule.
 
COMERICA'S SUPPORT OF SUBSIDIARY BANKS
 
     Under Federal Reserve Board policy, Comerica is expected to act as a source
of financial strength to each of its subsidiary banks and, if necessary, to
commit resources to support each of such subsidiaries. This support may be
required at times when, absent such Federal Reserve Board policy, Comerica would
not otherwise be required to provide it.
 
     Under the Financial Institutions Reform, Recovery, and Enforcement Act of
1989 ("FIRREA"), a depository institution insured by the FDIC can be held liable
for any loss incurred by, or reasonably expected to be incurred by, the FDIC
after August 9, 1989 in connection with (i) the default of a commonly controlled
FDIC-insured depository institution, or (ii) any assistance provided by the FDIC
to any commonly controlled FDIC-insured depository institution "in danger of
default." "Default" is defined generally as the appointment of a conservator or
receiver and "in danger of default" is defined generally as the existence of
certain conditions indicating that a default is likely to occur in the absence
of regulatory assistance.
 
     Under Michigan law, if the capital of a Michigan state chartered bank is
impaired by losses or otherwise, the Michigan Financial Institutions Bureau is
authorized to require payment of the deficiency by assessment upon the bank's
shareholders, pro rata, and to the extent necessary, if any such assessment is
not paid by any shareholder after three months' notice, to cause the sale of the
stock of such shareholder to make good the deficiency.
 
     Under the National Bank Act, if the capital stock of a national bank is
impaired by losses or otherwise, the Comptroller is authorized to require
payment of the deficiency by assessment upon the bank's shareholders, pro rata,
and to the extent necessary, if any such assessment is not paid by any
shareholder after three months' notice, to sell the stock of such shareholder to
make good the deficiency.
 
     Any capital loans by a bank holding company to any of its subsidiary banks
are subordinate in right of payment to deposits and to certain other
indebtedness of such subsidiary bank. In the event of a bank holding company's
bankruptcy, any commitment by the bank holding company to a federal bank
regulatory agency to maintain the capital of a subsidiary bank will be assumed
by the bankruptcy trustee and entitled to a priority of
 
                                       43
<PAGE>   51
 
payment. This priority would apparently apply to guarantees of capital plans
under the Federal Deposit Insurance Corporation Improvement Act of 1991
(discussed below) ("FDICIA").
 
FDIC INSURANCE ASSESSMENTS
 
     Comerica's subsidiary banks are subject to FDIC deposit insurance
assessments. On January 1, 1994, a permanent risk-based deposit premium
assessment system became effective under which each depositary institution is
placed in one of nine assessment categories based on certain capital and
supervisory measures. The assessment rates under the system range from 0.23
percent to 0.31 percent of domestic deposits depending upon the assessment
category into which the insured institution is placed. It is possible that such
assessments will be increased and it is possible that there may be special
additional assessments in the future. A significant increase in the assessment
rate or a special additional assessment could have an adverse impact on
Comerica's results of operations.
 
FDICIA
 
     In December 1991 FDICIA was enacted. This legislation substantially revises
the bank regulatory and funding provisions of the Federal Deposit Insurance Act
and makes revisions to several other federal banking statutes.
 
     Among other things, FDICIA requires the federal banking agencies to take
"prompt corrective action" in respect of depository institutions that do not
meet minimum capital requirements. FDICIA establishes five capital tiers: "well
capitalized," "adequately capitalized," "undercapitalized," "significantly
undercapitalized" and "critically undercapitalized." A depository institution's
capital tier depends upon where its capital levels are in relation to various
relevant capital measures, which includes a risk-based capital measure and a
leverage ratio capital measure, and certain other factors.
 
     A depository institution is well capitalized if it significantly exceeds
the minimum level required by regulation of each relevant capital measure,
adequately capitalized if it meets each such measure, undercapitalized if it
fails to meet any such measure, significantly undercapitalized if it is
significantly below any such measure and critically undercapitalized if it has a
ratio of tangible equity to total assets that is equal to or less than 2
percent. An institution may be deemed to be in a capitalization category that is
lower than is indicated by its actual capital position if, among other things,
it receives an unsatisfactory examination rating.
 
     Regulations establishing the specific capital tiers have been adopted.
Under these regulations, for an institution to be well capitalized it must have
a total risk-based capital ratio of at least 10 percent, a Tier 1 risk-based
capital ratio of at least 6 percent, and a Tier 1 leverage ratio of at least 5
percent, and not be subject to any specific capital order or directive. For an
institution to be adequately capitalized it must have a total risk-based capital
ratio of at least 8 percent, a Tier 1 risk-based capital ratio of at least 4
percent, and a leverage ratio of at least 4 percent (and in some cases 3
percent). Under these new regulations, the banking subsidiaries of Comerica
would be considered to be well capitalized as of September 30, 1994.
 
     FDICIA generally prohibits a depository institution from making any capital
distribution (including payment of a dividend) or paying any management fee to
its holding company if the depository institution would thereafter be
undercapitalized. Undercapitalized depository institutions are subject to growth
limitations and are required to submit a capital restoration plan. The federal
banking agencies may not accept a capital plan without determining, among other
things, that the plan is based on realistic assumptions and is likely to succeed
in restoring the depository institution's capital. In addition, for a capital
restoration plan to be acceptable, the depository institution's parent holding
company must guarantee that the institution will comply with such capital
restoration plan. The aggregate liability of the parent holding company is
limited to the lesser of (i) an amount equal to 5 percent of the depository
institution's total assets at the time it became undercapitalized, and (ii) the
amount that is necessary (or would have been necessary) to bring the institution
into compliance with all capital standards applicable with respect to such
institution as of the time it fails to comply with the plan. If a depository
institution fails to submit an acceptable plan, it is treated as if it were
significantly undercapitalized.
 
                                       44
<PAGE>   52
 
     Significantly undercapitalized depository institutions may be subject to a
number of requirements and restrictions, including orders to sell sufficient
voting stock to become adequately capitalized, requirements to reduce the total
assets and cessation of receipt of deposits from correspondent banks. Critically
undercapitalized institutions are subject to the appointment of a receiver or
conservator.
 
     Under FDICIA, the FDIC is permitted to provide financial assistance to an
insured bank before appointment of a conservator or receiver only if (i) such
assistance would be the least costly method of meeting the FDIC's insurance
obligations, (ii) grounds for appointment of a conservator or a receiver exist
or are likely to exist, (iii) it is unlikely that the bank can meet all capital
standards without assistance, and (iv) the bank's management has been competent,
has complied with applicable laws, regulations, rules and supervisory directives
and has not engaged in any insider dealing, speculative practice or other
abusive activity.
 
     FDICIA directs that each federal banking agency prescribe standards for
depository institutions and depository institution holding companies relating to
internal controls, information systems, internal audit systems, loan
documentation, credit underwriting, interest rate exposure, asset growth,
compensation, a maximum ratio of classified assets to capital, minimum earnings
sufficient to absorb losses, a minimum ratio of market value to book value for
publicly traded shares and other standards as they deem appropriate. Because
such standards have been proposed but not yet finalized, management is unable to
assess their impact.
 
     FDICIA also contains a variety of other provisions that may affect the
operations of depository institutions including new reporting requirements,
regulatory standards for real estate lending, "truth in savings" provisions, the
requirement that a depository institution give 90 days' prior notice to
customers and regulatory authorities before closing any branch and a prohibition
on the acceptance or renewal of brokered deposits by depository institutions
that are not well capitalized or are adequately capitalized and have not
received a waiver from the FDIC. Under regulations relating to the brokered
deposit prohibition, Comerica Bank is well capitalized and may accept brokered
deposits without restriction.
 
IMPLICATIONS OF BEING A SAVINGS AND LOAN HOLDING COMPANY
 
     As a result of Comerica's control of all of the capital stock of Comerica
Bank & Trust, F.S.B. ("Comerica FSB"), Comerica is a savings and loan holding
company under Section 10 of the Home Owners' Loan Act, as amended ("HOLA").
Comerica is registered with the Office of Thrift Supervision (the "OTS") and is
subject to OTS regulations, supervision and reporting requirements.
 
     With certain exceptions, a savings and loan holding company must obtain the
prior written approval of the OTS before acquiring control of an insured savings
association or savings and loan holding company through the acquisition of stock
or through a merger or some other business combination. HOLA prohibits the OTS
from approving an acquisition by a savings and loan holding company which would
result in the holding company controlling savings associations in more than one
state unless (i) the holding company is authorized to do so by the FDIC as an
emergency acquisition, (ii) the holding company controls a savings association
which operated an office in the additional state or states on March 5, 1987, or
(iii) the statutes of the state in which the savings association to be acquired
is located specifically permit a savings association chartered by such state to
be acquired by an out-of-state savings association or savings and loan holding
company.
 
     As a subsidiary of a savings and loan holding company, Comerica FSB is
subject to certain restrictions in its dealings with Comerica and with other
companies affiliated with Comerica. In addition, savings association
subsidiaries of savings and loan holding companies are required to give the OTS
thirty days' prior notice of any proposed payment of dividends to the savings
and loan holding company.
 
     As a federal savings bank, Comerica FSB is subject to the capital adequacy
guidelines of the OTS. In general, a federal savings bank is required to satisfy
three capital requirements: (i) a leverage test under which core capital must be
at least three percent of adjusted total assets, (ii) a tangible capital test
under which tangible capital must be at least 1.5% of adjusted total assets and
(iii) a risk based capital test under which core capital must, on a fully
phased-in basis, be at least 4% of risk adjusted assets and total capital must,
on a fully phased-in basis, be at least 8% of risk adjusted assets. The OTS has
proposed a regulation that would
 
                                       45
<PAGE>   53
 
increase the minimum leverage ratio from 3% to at least 4% to 5% for savings
associations not having the highest supervisory rating. As of September 30,
1994, Comerica FSB had capital well in excess of the foregoing requirements with
a leverage ratio of 6.75%, a tangible capital ratio of 6.75%, a core risk based
capital ratio of 11.14%, and a total risk based capital ratio of 12.40%.
 
     In general, a savings and loan holding company such as Comerica that has a
federal savings bank subsidiary that fails to meet the "qualified thrift lender"
test is required to become a bank holding company. As Comerica is already a bank
holding company, Comerica FSB's failure to satisfy the "qualified thrift lender"
test would have no material effect on Comerica. In addition, if a federal
savings bank, such as Comerica FSB, does not satisfy the "qualified thrift
lender" test, then such federal savings bank (i) will be limited to establishing
new branches as if it were a national bank located in the same state, (ii) will
be barred from obtaining new Federal Home Loan Bank advances, (iii) will be
prohibited from making any new investment or engaging in any new activity unless
the investment or activity is permitted for a national bank and (iv) will be
subject to the dividend restrictions applicable to national banks. Moreover,
three years after it has failed to qualify as "qualified thrift lender", a
federal savings bank must (i) divest any investments and activities not
permitted for a national bank and (ii) repay any of its outstanding Federal Home
Loan Bank advances "as promptly as can prudently be done" consistent with its
safe and sound operation and must divest any investment and cease any activity
not permitted for a national bank. Even if Comerica FSB failed the "qualified
thrift lender" test, Comerica does not believe that it would have a significant
effect on its operations.
 
     To be a "qualified thrift lender" a federal savings bank must maintain
"qualified thrift investments" of at least 65 percent of its "portfolio assets"
as measured on a monthly average basis in 9 out of the last 12 months. The
assets that qualify as "qualified thrift investments" include assets generally
related to the development of domestic residential real property. "Portfolio
assets" is defined as a federal savings bank's total assets, minus (i) goodwill
and other intangible assets, (ii) the value of property used by the savings
association to conduct its business and (iii) subject to a maximum of 20 percent
of total assets, liquid assets required to be maintained under Section 6 of
HOLA.
 
                     DESCRIPTION OF COMERICA CAPITAL STOCK
 
     The following description contains a summary of all of the material
features of the capital stock of Comerica but does not purport to be complete
and is subject to and qualified in its entirety by reference to the Comerica
Restated Certificate of Incorporation, including the Certificate of Designation
for the Comerica Series C Preferred Stock (the "Comerica Charter"), all of which
are filed as exhibits to the Registration Statement of which this Proxy
Statement/Prospectus forms a part and are incorporated herein by reference. See
also "COMPARISON OF SHAREHOLDER RIGHTS" below. The following description should
be read carefully by the UBT stockholders.
 
     Comerica's total authorized capital stock currently consists of (i)
10,000,000 shares of preferred stock, without par value (the "Comerica Preferred
Stock"), and (ii) 250,000,000 shares of Comerica Common Stock, with a par value
of $5.00 per share.
 
   
     With respect to the Comerica Preferred Stock, 500,000 shares with no stated
value have been designated as Series C Participating Preferred Stock (the
"Comerica Series C Preferred Stock"). All shares of two former series of
Comerica Preferred Stock, designated Adjustable Rate Cumulative Preferred Stock,
Series A and Series B Preferred Stock, have been redeemed and restored to the
status of authorized but unissued Comerica Preferred Stock. All shares
designated as Comerica Series C Preferred Stock have been reserved for issuance
in connection with the Comerica Rights. The Comerica Rights are not currently
exercisable and no shares of Comerica Series C Preferred Stock are outstanding.
For a description of the Comerica Rights, see "COMPARISON OF SHAREHOLDER RIGHTS
- -- Rights Plans" below.
    
 
   
     With respect to the Comerica Common Stock, as of September 30, 1994,
119,294,531 shares of Comerica Common Stock were issued and outstanding.

COMERICA PREFERRED STOCK
 
     General. The Comerica Preferred Stock may be issued in one or more series
at such time or times and for such consideration or considerations as Comerica's
Board may determine. The Comerica Board is expressly authorized at any time, and
from time to time, to provide for the issuance of Comerica Preferred Stock with
such voting powers or without voting powers, and with such designations,
preferences and relative, participating, optional or other special rights, and
qualifications, limitations or restrictions thereof, as shall be stated and
expressed in the Comerica Board resolution providing for the issuance thereof.
The Comerica Board is authorized to designate the series and the number of
shares comprising such series, the dividend rate on the shares of such series,
the redemption rights, if any, any purchase, retirement or sinking fund
provisions, any conversion rights and any special voting rights.
 
     Uncommitted authorized but unissued shares of Comerica Preferred Stock may
be issued from time to time to such persons and for such consideration as the
Comerica Board may determine and holders of the then outstanding shares of
Comerica Common Stock or Comerica Preferred Stock may or may not be given the
opportunity to vote thereon, depending upon the nature of any such transactions,
applicable law, the rules and policies of NYSE and the judgment of the Comerica
Board regarding the submission of such issuance to Comerica's shareholders.
Comerica shareholders have no preemptive rights to subscribe to newly issued
shares.
 
     Moreover, it is possible that shares of Comerica Preferred Stock would be
issued for the purpose of making an acquisition by an unwanted suitor of a
controlling interest in Comerica more difficult, time-consuming or costly or
otherwise to discourage an attempt to acquire control of Comerica. Under such
circumstances the availability of authorized and unissued shares of Comerica
Common Stock and Comerica Preferred Stock may make it more difficult for
shareholders to obtain a premium for their shares. Such authorized and unissued
shares could be used to create voting or other impediments or to frustrate a
person seeking to obtain control of Comerica by means of a merger, tender offer,
proxy contest or other means. Such shares could be privately placed with
purchasers who might cooperate with the Comerica Board in opposing such an
attempt by a third party to gain control of Comerica. The issuance of shares of
Comerica Preferred Stock could also be used to dilute ownership of a person or
entity seeking to obtain control of Comerica. Although Comerica does not
currently contemplate taking such action, shares of one or more series of
Comerica Preferred Stock could be issued for the purposes and effects described
above and the Comerica Board reserves its rights (if consistent with its
fiduciary responsibilities) to issue such stock for such purposes.
 
     Shares of Comerica Preferred Stock redeemed or acquired by Comerica may
return to the status of authorized and unissued shares of Comerica Preferred
Stock, without designation as to series, and may be reissued by the Comerica
Board.
 
     Comerica Series C Preferred Stock. The Comerica Series C Preferred Stock is
issuable upon exercise of the Comerica Rights. The Comerica Rights are not
currently exercisable and no shares of Comerica Series C Preferred Stock are
outstanding. For a description of the Comerica Rights, see "COMPARISON OF
SHAREHOLDER RIGHTS -- Rights Plan" below. The Comerica Series C Preferred Stock
carries a quarterly dividend rate equal (rounded to the nearest cent) to the
greater of (a) $10 or (b) a multiple (the "Comerica Multiple") times the
aggregate per share amount of all cash dividends and the Comerica Multiple times
the aggregate per share amount of all non-cash dividends or other distributions
other than a dividend payable in shares of Comerica Common Stock or a
subdivision of the outstanding shares of Comerica Common Stock, declared on the
Comerica Common Stock during the period specified. Dividends on the Comerica
Series C Preferred Stock are cumulative. The Comerica Multiple, which is subject
to adjustment upon the occurrence of stock dividends on, or splits or
combinations of, outstanding Comerica Common Stock is 450. Unless all dividends
on the Comerica Series C Preferred Stock have been paid in full, no dividend may
be declared or paid on the Comerica Common Stock. If dividends shall be in
arrears in an amount equal to six quarterly dividends, the holders of the
Comerica Series C Preferred Stock shall have the right, voting as a class, to
elect two directors.
 
     Each share of Comerica Series C Preferred Stock is entitled to vote on all
matters submitted to a vote of the shareholders of Comerica, the number of votes
being subject to adjustment under the same circumstances
 
                                       47
<PAGE>   55
 
which require an adjustment of the Comerica Multiple but may not have more than
one vote per share. Except as otherwise required by the Comerica Charter or
bylaws, the holders of shares of Comerica Series C Preferred Stock and the
holders of Comerica Common Stock vote together as one class.
 
     Upon any liquidation, dissolution or winding up of Comerica, each share of
Comerica Series C Preferred Stock is entitled, prior to any payment or
distribution in respect of the Comerica Common Stock, to a liquidation
preference equal to $100 plus any accrued and unpaid dividends. If sufficient
assets of Comerica remain after payment of the liquidation preference in respect
of the Comerica Series C Preferred Stock and certain payments to the holders of
Comerica Common Stock, the Comerica Series C Preferred Stock participates with
the Comerica Common Stock in respect of the remaining assets of Comerica based
on a ratio.
 
     If Comerica enters into any consolidation, merger, combination or other
transaction in which Comerica Common Stock is exchanged for other stock,
securities, cash or other property, then the shares of Comerica Series C
Preferred Stock will at the same time be similarly exchanged in an amount per
share, subject to certain adjustments, equal to the Comerica Multiple times the
aggregate amount of stock, security, cash or other property into which or for
which each share of Comerica Common Stock is changed or exchanged.
 
COMERICA COMMON STOCK
 
     Subject to the rights of any outstanding shares of Comerica Preferred
Stock, the holders of Comerica Common Stock are entitled to receive such
dividends as may from time to time be declared by the Comerica Board. They are
entitled to one vote per share of Comerica Common Stock on every issue submitted
to them as Comerica shareholders at a meeting of shareholders or otherwise. In
the event of liquidation they are entitled, after payment in full of the
liquidation preference of any outstanding Comerica Preferred Stock and subject
to the right of the holders of Comerica Series C Preferred Stock to participate
in certain distributions, to share ratably in all assets of Comerica available
for distribution to holders of Comerica Common Stock. Holders of shares of
Comerica Common Stock do not have preemptive or cumulative voting rights. All
shares of Comerica Common Stock now issued and outstanding are fully paid and
nonassessable.
 
     The registrar and transfer agent for the Comerica Common Stock is Norwest
Bank, Minnesota, National Association.
 
                        DESCRIPTION OF UBT CAPITAL STOCK
 
     UBT's total authorized capital stock currently consists of 6,000,000 shares
of Common Stock, with no par value (the "UBT Common Stock").
 
     Holders of UBT Common Stock are entitled to one vote per share on all
matters to be voted upon by the stockholders of UBT. The holders of UBT Common
Stock are entitled to receive ratably such dividends, if any, as may be declared
by the UBT Board of Directors out of funds legally available therefor. In the
event of liquidation, dissolution or winding up of UBT, the holders of UBT
Common Stock are entitled to share ratably in all assets remaining after payment
of liabilities. The UBT Common Stock has no preemptive, redemption, conversion
or other subscription rights. The outstanding shares of UBT Common Stock are
fully paid and nonassessable.
 
     As of September 30, 1994, there were 1,339,697 shares of UBT Common Stock
outstanding held by 509 holders of record.
 
     The transfer agent and registrar for the UBT Common Stock is First
Interstate Bank of California.
 
                        COMPARISON OF SHAREHOLDER RIGHTS
 
     In the event the proposed Merger is consummated, stockholders of UBT whose
shares of UBT Common Stock, are converted into shares of Comerica Common Stock
will become shareholders of Comerica. Their
 
                                       48
<PAGE>   56
 
rights will be governed by Delaware law and the Comerica Charter and the
Comerica Bylaws (the "Comerica Bylaws").
 
     Certain differences between the rights of holders of UBT Common Stock and
the holders of Comerica Common Stock are set forth below. UBT is organized under
the laws of California and Comerica is organized under the laws of Delaware, and
there are differences arising from various provisions of the Comerica Charter,
the Comerica Bylaws, the UBT Articles of Incorporation (the "UBT Charter"), the
UBT Bylaws, the "Comerica Rights Agreement" (See "Rights Plans" below) and state
laws. This summary contains a description of the material differences, but is
not meant to be relied upon as an exhaustive list or detailed description of the
provisions discussed and is qualified in its entirety by reference to the DGCL,
California state law, the Comerica Charter, the Comerica Bylaws, the UBT
Charter, the UBT Bylaws and the Comerica Rights Agreement.
 
CLASSIFICATION, REMOVAL AND NOMINATION OF BOARD OF DIRECTORS
 
     The Comerica Charter provides for classification of the Comerica Board into
three classes of directors with each class as nearly equal in number as possible
and elected for a three-year term, and with only one class standing for election
each year. The total number of directors and the number of directors
constituting each class may be fixed or changed from time to time by the
Comerica Board without shareholder approval. The Comerica Board currently
consists of 14 members. The affirmative vote of the holders of at least 75% of
Comerica's then outstanding voting stock is required to amend, change, or repeal
this provision unless such amendment, change, or repeal is approved by
three-fourths of the Comerica Board, in which case such amendment, change, or
repeal will only require the affirmative vote of a majority of shares entitled
to vote thereon. The Comerica Charter contains no provisions concerning the
removal of directors. Under the DGCL, then, Comerica shareholders may remove a
Comerica director only for cause.
 
     Nominations of candidates for election as directors of Comerica at any
election meeting may be made by the Directors' Committee of the Board of
Directors until June 18, 1995, and thereafter by the Board of Directors.
Shareholders may nominate directors by delivering notice to the Secretary of
Comerica not less than 30 days prior to the date of the election meeting,
outlining in the notice (a) the name, age, business address and residence of
each nominee proposed in the notice, (b) the principal occupation or employment
of each such nominee, (c) the number of shares of Comerica Capital Stock which
are beneficially owned by each such nominee, and (d) such other information
concerning each such nominee as would be required in a proxy statement
soliciting proxies for the election of such nominee.
 
     The UBT Bylaws provide that the UBT Board of Directors shall consist of not
less than 7 nor more than 13 directors, until changed by amendment of the
Articles of Incorporation or, if not prohibited by the Articles, by an amendment
to the Bylaws adopted by the shareholders. The exact number of directors within
the range mentioned above is fixed at 9 and may be reduced or increased within
the range by a resolution duly adopted by the Board of Directors. Directors need
not be shareholders of the corporation.
 
     Board of Director nominations may be made by the Board of Directors or by
any shareholder of any outstanding class of capital stock of the corporation
entitled to vote for the election of directors. Notice of intention to make any
nominations shall be made in writing and shall be delivered or mailed to the
President of UBT not less than 21 days nor more than 60 days prior to any
meeting of shareholders called for the election of directors; provided however,
that if less than 21 days' notice of the meeting is given to shareholders, such
notice of intention to nominate shall be mailed or delivered to the President of
UBT not later than the close of business on the tenth day following the day on
which the notice of meeting was mailed; provided further, that if notice of such
meeting is sent by third class mail, no notice of intention to make nominations
shall be required. Such notification shall contain the following information to
the extent known to the notifying shareholder: (a) the name and address of each
proposed nominee; (b) the principal occupation of each proposed nominee; (c) the
number of shares of capital stock of UBT owned by each proposed nominee; (d) the
name and residence address of the notifying shareholder; and (e) the number of
shares of capital stock of UBT owned by the notifying shareholder. Nominations
not made in accordance herewith may, in the
 
                                       49
<PAGE>   57
 
discretion of the Chairperson of the meeting, be disregarded and upon the
Chairperson's instructions, the inspectors of election can disregard all votes
cast for each such nominee.
 
SPECIAL MEETINGS OF SHAREHOLDERS
 
     The Comerica Bylaws provide that a special meeting of shareholders may be
called only by (i) the Chairman of the Board of Comerica or, during such
Chairman's absence or disability, by the President of Comerica, or (ii) by the
President or Secretary of Comerica at the request in writing of a majority of
the Comerica Board, or at the request in writing by shareholders owning at least
75% of the then outstanding Comerica voting stock entitled to vote at the
meeting. Pursuant to the Comerica Charter, any amendment, alteration, change,
addition to, or repeal of this Comerica Bylaw provision proposed by a Comerica
shareholder requires the affirmative vote of the holders of at least 75% of
Comerica's then outstanding voting stock, and the same super majority
shareholder vote is required to amend, change, or repeal this Comerica Charter
provision, except under the circumstances described above under "--
Classification, Removal, and Nomination of Board of Directors."
 
     The UBT Bylaws provide that special meetings of shareholders may be called
by the Board of Directors, or by the shareholders entitled to cast not less than
10% of the votes at the meeting.
 
LIMITATION OF LIABILITY OF DIRECTORS
 
     The DGCL permits, and the Comerica Charter provides, that a director shall
not be personally liable to Comerica or its shareholders for monetary damages
for breach of fiduciary duty as a director, except for liability (a) for any
breach of the director's duty of loyalty to the corporation or its shareholders,
(b) for acts or omissions not in good faith or that involve intentional
misconduct or a knowing violation of law, (c) for the approval of an illegal
dividend, asset distribution, stock purchase, or certain other illegal actions,
or (d) for any transaction for which the director derived an improper personal
benefit.
 
     The UBT Charter and Bylaws provide that, the liability of directors of UBT
for monetary damages shall be eliminated to the fullest extent permitted under
California law.
 
ACTION BY WRITTEN CONSENT
 
     The Comerica Charter permits shareholder action by written consent only if
such consent is taken by not less than 75% of the outstanding voting stock of
Comerica. The affirmative vote of the holders of at least 75% of Comerica's then
outstanding voting stock is required to amend, change, or repeal this Comerica
Charter provision.
 
     The UBT Bylaws permit shareholder action by written consent only if the
consent is signed by the holders of outstanding shares having not less than the
minimum number of votes necessary to authorize such action at a meeting at which
all shares entitled to vote were present, except that unanimous written consent
is required for election of directors to non-vacant positions.
 
CERTAIN BUSINESS COMBINATIONS
 
     Section 203 of the DGCL. Delaware has enacted a business combination
statute (Section 203 of the DGCL) pursuant to which a corporation having a class
of voting stock listed on a national securities exchange or authorized for
quotation on a national inter-dealer quotation system or held of record by more
than 2,000 shareholders, and whose charter or bylaws do not provide that the
corporation shall not be governed by the statute shall not engage in any
business combination (defined as any merger or consolidation of the corporation
or its subsidiary) with any interested shareholder (defined generally as any
person owning or recently owning 15% of more of the outstanding voting stock of
the corporation) for a period of 3 years following the date that such
shareholder became an interested shareholder, unless (a) prior to such date the
board of directors of the corporation approved either the business combination
or the transaction which resulted in the shareholder becoming an interested
shareholder, or (b) the interested shareholder owned at least 85% of the voting
stock of the corporation outstanding at the time the transaction commenced,
excluding
 
                                       50
<PAGE>   58
 
for purposes of determining the number of shares outstanding those shares owned
(i) by persons who are directors and also officers and (ii) employee stock plans
in which employee participants do not have the right to determine confidentially
whether shares held subject to the plan will be tendered in a tender or exchange
offer, or (c) on or subsequent to such date the business combination is approved
by the board of directors and authorized at an annual or special meeting of
shareholders, and not by written consent, by the affirmative vote of at least 66
and 2/3% of the outstanding voting stock which is not owned by the interested
shareholder.
 
     Comerica Charter Provisions With Respect to Certain Business
Combinations. The Comerica Charter provides that any "Business Combination"
(hereinafter referred to as a "Comerica Business Combination") involving
Comerica and a person who beneficially owns 10% or more of Comerica's capital
stock (a "Comerica Related Person") must be approved by (i) the holders of at
least 75% of the votes entitled to be cast by the holders of Comerica's voting
stock and (ii) a majority of the votes entitled to be cast by the holders of
such voting stock, excluding stock beneficially owned by such Comerica Related
Person (the "Comerica Voting Requirement"). The Comerica Voting Requirement does
not apply if the Comerica Business Combination is approved by three-fourths of
the Comerica Continuing Directors (defined generally to include each director
who either was a director immediately prior to the time the Comerica Related
Person in the Comerica Business Combination became such a person or was
designated as a Comerica Continuing Director by a majority of the then Comerica
Continuing Directors prior to initial election as a director), or complies with
certain minimum price and other requirements. As defined in the Comerica
Charter, a Comerica Business Combination includes, among other things, (i) any
merger or consolidation of Comerica with, into, or for the benefit of a Comerica
Related Person; (ii) the sale by Comerica of a Substantial Part (more than 10%
of the fair market value) of its assets to a Comerica Related Person; (iii) the
acquisition by Comerica of a Substantial Part of the assets of a Comerica
Related Person; (iv) the issuance by Comerica of any of its securities to a
Comerica Related Person (other than an issuance which is effected on a pro rata
basis to all Comerica shareholders); or (v) the acquisition by Comerica of any
securities of a Comerica Related Person. This provision of the Comerica Charter
cannot be amended, changed, or repealed except by a vote similar to the Comerica
Voting Requirement unless such amendment, change, or repeal is recommended by
three-fourths of the Comerica Continuing Directors, in which case such
amendment, change, or repeal will require such vote, if any, as otherwise is
required by Delaware law.
 
     The California Corporations Code does not have a business combination
statute. The UBT Charter does not have a comparable business combination
provisions.
 
AMENDMENT OF CERTIFICATE OF INCORPORATION
 
     The Comerica Charter provides that any amendment, change, or repeal of such
charter with respect to the provisions relating to (i) size and classification
of the Comerica Board, (ii) certain amendments to the provisions of the Comerica
Bylaws relating to calling special meetings of shareholders and nominations of
director candidates, (iii) Business Combinations, and (iv) actions of
shareholders permitted by written consent must be approved by a vote of at least
75% of the then outstanding shares of capital stock entitled to vote (and, with
respect to amending provisions relating to Business Combinations, a majority of
the outstanding shares of capital stock entitled to vote of which a Related
Person is not a beneficial owner); provided, however, that such voting
requirements are not required by any proposed amendment, change, or repeal
recommended to shareholders by not less than three-fourths of the Comerica Board
(or, with respect to such proposals relating to Business Combinations,
three-fourths of the Comerica Continuing Directors (as defined above)).
 
     Pursuant to California law, the Charter of UBT may be amended by the
approval of the UBT Board of Directors and the affirmative vote or written
consent of a majority of the outstanding shares entitled to vote.
 
RIGHTS PLANS
 
     Comerica Rights Plan. On January 26, 1988, the Comerica Board declared a
dividend distribution of one right (each, a "Comerica Right") for each
outstanding share of Comerica Common Stock to shareholders of record at the
close of business on February 8, 1988. Each Comerica Right entitles the
registered holder to
 
                                       51
<PAGE>   59
 
purchase from Comerica a unit consisting of 1/100th of one share (a "Unit") of
Comerica Series C Preferred Stock at a Purchase Price (the "Comerica Purchase
Price") of $175 in cash per Unit, subject to adjustment. The number of Comerica
Rights per share of Comerica Common Stock is subject to adjustment in certain
events described below. Each share of Comerica Common Stock currently carries
2/9ths of one Comerica Right. The Comerica Common Stock to be issued in the
Merger will have attached thereto the associated number of Rights. The
description and terms of the Comerica Rights are set forth in a Rights Agreement
(the "Comerica Rights Agreement"), dated as of January 28, 1988, as amended,
between Comerica and Comerica Bank, as Rights Agent (the "Comerica Rights
Agent").
 
     At the present time, the Comerica Rights attach to all Comerica Common
Stock certificates representing outstanding shares, and no separate Comerica
Rights certificates have been distributed. The Comerica Rights will separate
from the Comerica Common Stock and a "Comerica Distribution Date" will occur
upon the earlier of (i) ten days following a public announcement that a person
or group of affiliated or associated persons (a "Comerica Acquiring Person") has
acquired, or obtained the right to acquire, beneficial ownership of 20 percent
or more of the outstanding shares of Comerica Common Stock (the "Comerica Stock
Acquisition Date"), or (ii) ten business days following the commencement of a
tender offer or exchange offer that would result in a person or group
beneficially owning 25% or more of such outstanding shares of Comerica Common
Stock. Until a Comerica Distribution Date, (i) the Comerica Rights will be
evidenced by the Comerica Common Stock certificates and will be transferred with
and only with such Comerica Common Stock certificates, (ii) new Comerica Common
Stock certificates issued after February 8, 1988 will contain a notation
incorporating the Comerica Rights Agreement by reference, and (iii) the
surrender for transfer of any certificates for Comerica Common Stock outstanding
will also constitute the transfer of the Comerica Rights associated with the
Comerica Common Stock represented by such certificates.
 
     The Comerica Rights are not exercisable until the Comerica Distribution
Date and will expire at the earlier of (i) the close of business on February 8,
1998, and (ii) the date which is 24 months after the first date upon which
Comerica can generally be acquired by bank holding companies, and Comerica is
generally permitted to acquire banks, principally located in at least 15 of the
20 states listed on Exhibit D to the Comerica Rights Agreement, unless earlier
redeemed by Comerica as described below. Pursuant to the Comerica Rights
Agreement, Comerica reserves the right to require prior to the occurrence of a
Comerica Triggering Event (as defined below) that, upon any exercise of Comerica
Rights, a number of Comerica Rights be exercised so that only whole shares of
Comerica Series C Preferred Stock will be issued.
 
     As soon as practicable after a Comerica Distribution Date, Comerica Rights
certificates will be mailed to holders of record of the Comerica Common Stock as
of the close of business on the Comerica Distribution Date and, thereafter, the
separate Comerica Rights certificates alone will represent the Comerica Rights.
Except as otherwise determined by the Comerica Board and except in connection
with the shares of Comerica Common Stock issued upon the exercise of employee
stock options or the conversion of convertible securities, only shares of
Comerica Common Stock issued prior to the Comerica Distribution Date will be
issued with Comerica Rights. The number of Comerica Rights per share of Comerica
Common Stock is subject to adjustment upon the occurrence of stock dividends on,
or splits or combinations of, outstanding Comerica Common Stock. Currently, each
share of Comerica Common Stock currently carries 2/9ths of one Comerica Right.
 
     In the event that, at any time following the Comerica Distribution Date,
(i) a person becomes the beneficial owner of more than 25 percent of the then
outstanding shares of Comerica Common Stock except pursuant to an offer for all
outstanding shares of Comerica Common Stock which the independent directors
serving on the Comerica Board determine to be fair to, and otherwise in the best
interests of, Comerica shareholders, or (ii) Comerica is the surviving
corporation in a merger with a Comerica Acquiring Person and the Comerica Common
Stock is not changed or exchanged, each holder of a Comerica Right will
thereafter have the right to receive, upon exercise, Comerica Common Stock (or,
in certain circumstances, cash, property, or other securities of Comerica)
having a value equal to two times the exercise price of the Comerica Right.
Notwithstanding the foregoing, following the occurrence of any of the events set
forth in this paragraph, all Comerica Rights that are, or (under certain
circumstances specified in the Comerica Rights Agreement) were, beneficially
owned by any Comerica Acquiring Person will be null and void. However, Comerica
Rights
 
                                       52
<PAGE>   60
 
are not exercisable following the occurrence of either of the events set forth
above until such time as the Comerica Rights are no longer redeemable by
Comerica as set forth below.
 
     In the event that, at any time following the Comerica Stock Acquisition
Date, (i) Comerica is acquired in a merger or other business combination
transaction in which Comerica is not the surviving corporation or Comerica
Common Stock is changed or exchanged (other than a merger which follows an offer
described in clause (i) of the preceding paragraph), or (ii) 50 percent or more
of Comerica's assets or earning power is sold or transferred, each holder of a
Comerica Right (except Comerica Rights which previously have been voided as set
forth above) shall thereafter have the right to receive, upon exercise, common
stock of the acquiring company having a value equal to two times the exercise
price of the Comerica Right. Each of the events set forth in this paragraph and
in the preceding paragraph is referred to as a "Comerica Triggering Event."
 
     The Comerica Purchase Price payable, and the number of Units of Comerica
Series C Preferred Stock or other securities or property issuable, upon exercise
of the Comerica Rights are subject to adjustment in certain events.
 
     At any time until ten days following the Comerica Stock Acquisition Date,
Comerica may redeem the Comerica Rights in whole, but not in part, at a price of
$0.05 per Comerica Right, subject to adjustment where appropriate (payable in
cash, stock, or other consideration deemed appropriate by the Comerica Board).
After the redemption period has expired, Comerica's right of redemption may be
reinstated if a Comerica Acquiring Person reduces his or her beneficial
ownership to 10 percent or less of the outstanding shares of Comerica Common
Stock in a transaction or series of transactions not involving Comerica.
Immediately upon the action of the Comerica Board ordering redemption of the
Comerica Rights, the Comerica Rights will terminate and the only right of the
holders of Comerica Rights will be to receive the $0.05 redemption price.
 
     Until a Comerica Right is exercised, the holder thereof, as such, will have
no rights as a holder of Comerica shares, including, without limitation, the
right to vote or to receive dividends.
 
     Other than those provisions relating to the principal economic terms of the
Comerica Rights, any of the provisions of the Comerica Rights Agreement
(including the provisions relating to the termination of such agreement) may be
amended by the Comerica Board prior to the Comerica Distribution Date. After the
Comerica Distribution Date, the provisions of the Comerica Rights Agreement may
be amended by the Comerica Board in order to cure any ambiguity, to make changes
which do not adversely affect the interests of holders of Comerica Rights
(excluding the interests of any Comerica Acquiring Person), or to shorten or
lengthen any time period under the Comerica Rights Agreement; provided, however,
that no amendment to adjust the time period governing redemption shall be made
at such time as the Comerica Rights are not redeemable.
 
     The Comerica Rights have certain anti-takeover effects. The Comerica Rights
will cause substantial dilution to a person or group that attempts to acquire
Comerica on terms not approved by the Comerica Board, unless the offer is
conditional on a substantial number of Comerica Rights being acquired. The
Comerica Rights, however, should not affect any prospective offeror willing to
make an offer at a fair price and otherwise in the best interests of Comerica
and its shareholders as determined by a majority of the independent directors on
the Comerica Board, or willing to negotiate with the Comerica Board. The
Comerica Rights should not interfere with any merger or other business
combination approved by the Comerica Board since the Comerica Board may, at its
option, at any time until ten days following the Comerica Stock Acquisition Date
redeem all but not less than all of the then outstanding Comerica Rights at the
$0.05 redemption price.
 
     The Comerica Rights Agreement is incorporated herein by reference. See
"INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE" above. The foregoing
description of the Comerica Rights does not purport to be complete and is
qualified in its entirety by reference to the Comerica Rights Agreement, as
amended.
 
     UBT does not have a rights plan.

LIQUIDATED DAMAGES; CANCELLATION FEE

under "THE MERGER AGREEMENT" -- Conditions to the Merger -- "Conditions in favor
of Comerica and Interim" under items (i), (ii), (iii), (iv), (v), (vi), (vii),
(ix), (xii), (xiii) and (xviii) where such failure shall have been caused in
whole or in part by any action or inaction within the control of UBT, or any
Subsidiary of UBT or the directors of any of UBT or UBT's Subsidiaries.
 
     The Merger Agreement provides that, in the event of termination by UBT of
this Agreement because Interim or Comerica has breached any of their
representations and warranties set forth in the Merger Agreement and in the
reasonable opinion of UBT such breach cannot be cured prior to closing and would
have a Material Adverse Effect on Interim or Comerica or because of a default by
Comerica or Interim pursuant to the Merger Agreement and the continuance of such
failure for a period of 20 Business Days after written notice of such default,
in the reasonable opinion of UBT, cannot be cured prior to the closing, then
Comerica and Interim, jointly and severally, shall pay to UBT as reasonable and
full liquidated damages and reasonable compensation for the loss sustained
thereby and not as a penalty or forfeiture, the sum of $2,000,000, within ten
(10) Business Days following such occurrence.
 
EXPENSES
 
     Whether or not the Merger is consummated, all costs and expenses incurred
in connection with the Merger Agreement and the transactions contemplated
thereby shall be paid by the party incurring the same; provided, however, that
Comerica will file on a timely basis the reports required by Rule 144(c) of the
Securities Act. UBT's expenses incurred in connection with the Merger Agreement
and the transactions contemplated therein, including attorneys', accountants',
investment bankers' and any other fees, collectively shall not exceed the sum of
$1,500,000 without the prior written consent of Comerica which shall not be
unreasonably withheld.
 
SHAREHOLDER AGREEMENTS
 
     As noted above in item (xix) under the caption "Conditions to the Merger --
Conditions in favor of Comerica and Interim," the Merger is conditioned upon
delivery by each of the UBT director-stockholders of a Shareholder Agreement,
the form of which is prescribed by the Merger Agreement. The Shareholder
Agreement obligates each of the members of the UBT Board of Directors who own
shares of UBT Common Stock to vote those shares, as well as any other shares of
UBT Common Stock over which any such director exercises voting power, in favor
of the Merger at any stockholder meeting or in connection with any solicitation
of stockholder written consent occurring prior to August 31, 1995, subject to
fiduciary obligations. Pursuant to the Shareholder Agreement, each
director-stockholder also agrees not to pledge or otherwise encumber, or to
sell, assign or otherwise dispose of, any of such director-stockholder UBT
Common Stock, or enter into any agreement to do any of the foregoing, until (i)
adjournment of the special meeting of UBT stockholders called to approve the
Merger, (ii) termination of the Merger Agreement in accordance with its terms,
or (iii) August 31, 1995, except with Comerica's prior written consent or
pursuant to the Merger. Finally, the Shareholder Agreement obligates each
director-stockholder not to directly or indirectly solicit or initiate any
inquiries, proposals or offers from any person or entity other than Comerica or
an affiliate of Comerica, or vote in favor of, any proposal or transaction for
disposition of, the business or assets of UBT or any of its subsidiaries, the
acquisition of the securities of UBT or any such subsidiary, or any business
combination other than with Comerica or one of its affiliates.
 
RESALES BY AFFILIATES
 
     Pursuant to the terms of the Merger Agreement, certain persons believed by
UBT to be "affiliates" (as defined in Rule 144 of the Securities Act of 1933) of
UBT have entered into an "Affiliate's Agreement." The Affiliate's Agreement
generally provides that affiliates of UBT may not sell or otherwise dispose of
(a) any
 
                                       61
<PAGE>   69
 
shares of UBT Common Stock currently owned by them or any shares of Comerica
Common Stock received pursuant to the Merger, for a period beginning not less
than thirty days prior to the consummation of the Merger and ending on the date
that Comerica publishes financial results covering a period of at least thirty
days of combined operations of UBT and Comerica following the consummation of
the Merger (except that such affiliates may exchange their shares of UBT Common
Stock for shares of Comerica Common Stock in the Merger), or (b) any shares of
Comerica Common Stock received pursuant to the Merger or any securities that may
be distributed with respect thereto or issued in exchange or substitution
therefor (collectively, the "Restricted Securities"), or any option, right or
other interest with respect to any Restricted Securities, unless such sale or
other disposition is effected (i) pursuant to an exemption from the registration
requirements of the Securities Act, or (ii) pursuant to an effective
registration statement under the Securities Act. Notwithstanding the foregoing,
affiliates may make bona fide gifts of such shares of Comerica Common Stock so
long as the recipients thereof agree not to sell or otherwise dispose of the
Comerica Common Stock except as provided in the Affiliate's Agreement. Because
the Merger is currently expected to qualify as a purchase for accounting and
financial reporting purposes, affiliates may be relieved from certain
restrictions in the Affiliate's Agreement which relate to treatment of the
Merger as a pooling of interests for accounting purposes.
 
AMENDMENT AND WAIVER
 
     Subject to applicable law, (i) the Merger Agreement may be amended by
action taken or authorized by the respective boards of directors of Comerica,
Interim and UBT, as the case may be, or the duly authorized committees thereof,
at any time before or after approval by the stockholders of UBT; provided,
however, that after any such approval by the stockholders, no amendment shall be
made which by law requires further approval by such stockholders without such
further approval; and (ii) any term or provision of the Merger Agreement may be
waived in writing at any time by the party which is entitled to the benefits of
the specific term or provision Neither Comerica nor UBT has determined under
what circumstances it would waive any of the terms and provisions of the Merger
Agreement.
 
                           THE STOCK OPTION AGREEMENT
 
     The following is a brief summary of certain provisions of the Stock Option
Agreement, dated as of October 4, 1994, between UBT and Comerica, which is
attached hereto as Annex E. The following summary is qualified in its entirety
by reference to the Stock Option Agreement.
 
     Under the Stock Option Agreement, UBT has granted to Comerica an
irrevocable option to purchase up to 137,718 shares of UBT Common Stock at a per
share exercise price equal to $38.50, which was calculated on the basis of the
average of the closing prices for UBT Common Stock on the NASDAQ National Market
System for the seven trading days ending on the date of the Stock Option
Agreement.
 
     The option is exercisable only upon the occurrence of one of the following
events (each a "Purchase Event"):
 
          (a) UBT fails to publicly oppose a Tender Offer or an Exchange Offer
     (as defined below) or authorizes, recommends, publicly proposes or publicly
     announces an intention to authorize, recommend or propose, or enters into
     an agreement with any person (other than Comerica or any of its
     subsidiaries) to (i) effect a merger, consolidation or similar transaction
     involving UBT or any of its subsidiaries (other than internal mergers,
     reorganizations, consolidations or dissolutions involving only existing
     subsidiaries), (ii) except as permitted in the Merger Agreement, sell,
     lease, exchange or otherwise dispose of 15% or more of the consolidated
     assets of UBT and its subsidiaries, or (iii) issue, sell or otherwise
     dispose of (including by merger, consolidation, share exchange or similar
     transaction) securities representing 10% or more of the voting power of UBT
     or any of its subsidiaries (any of the foregoing an "Acquisition
     Transaction"); or
 
          (b) any person (other than Comerica or its subsidiaries) shall have
     acquired beneficial ownership (as defined under the Exchange Act) of or the
     right to acquire beneficial ownership of, or any group (as
 
                                       62
<PAGE>   70
 
     defined in the Exchange Act) shall have been formed which beneficially owns
     or has the right to acquire beneficial ownership of 15% or more of the
     outstanding common stock of UBT.
 
     The option will terminate upon the earliest to occur of (i) the moment in
time which is immediately prior to the Effective Time, (ii) 12 months after the
first occurrence of a Purchase Event, (iii) 18 months after the termination of
the Merger Agreement following the occurrence of a Preliminary Purchase Event
(as defined below), (iv) termination of the Merger Agreement in accordance with
the terms thereof prior to the occurrence of a Purchase Event or a Preliminary
Purchase Event (other than a termination by Comerica if the Merger Agreement,
the subsidiary Merger Agreement and the merger are not ratified and approved by
UBT's shareholder's company or by Comerica and UBT upon the mutual consent of
their Board of Directors if UBT at that time was entitled to terminate the
merger because the Merger Agreement, the Subsidiary Merger Agreement and the
Merger were not ratified by UBT's shareholders, or (v) 12 months after the
termination of the Merger Agreement by Comerica if the Merger Agreement, the
Subsidiary Merger Agreement and the Merger are not ratified and approved by
UBT's shareholder's company or by Comerica and UBT upon the mutual consent of
their Board of Directors if UBT at that time was entitled to terminate the
merger because the Merger Agreement, the Subsidiary Merger Agreement and the
Merger whereas not ratified by UBT's shareholders (provided, however, that if
within 12 months after such termination of the Merger Agreement a Purchase Event
or Preliminary Purchase Event occurs, then the option will terminate 12 months
after the first occurrence of such event). The closing of a purchase of shares
pursuant to the Stock Option Agreement is subject to the obtaining of all
necessary governmental approvals.
 
     For purposes of the Stock Option Agreement, each of the following events is
a "Preliminary Purchase Event":
 
          (a) any person (other than Comerica or any of its subsidiaries) shall
     have commenced (as defined in the Exchange Act), or shall have filed a
     registration statement under the Securities Act with respect to, a tender
     offer or exchange offer for shares of UBT's Common Stock which, upon
     consummation of such offer, would result in such person owning or
     controlling 15% or more of the outstanding common stock of UBT (such an
     offer being referred to as a "Tender Offer" or an "Exchange Offer,"
     respectively);
 
          (b) the stockholders of UBT shall not have approved the Merger
     Agreement at the meeting of such stockholders held for the purpose of
     voting on the Merger Agreement, such meeting shall not have been held or
     shall have been canceled prior to termination of the Merger Agreement or
     the Board of Directors of UBT shall have withdrawn or modified in a manner
     adverse to Comerica the recommendation of such Board of Directors with
     respect to the Merger Agreement, in each case after it shall have been
     publicly announced that any person (other than Comerica or any subsidiary
     of Comerica) shall have (i) made, or disclosed an intention to make, a
     proposal to engage in an Acquisition Transaction, or (ii) commenced a
     Tender Offer or filed a registration statement under the Securities Act
     with respect to an Exchange Offer.
 
     The number and type of securities subject to the option and the purchase
price of shares will be adjusted for any change in the UBT's Common Stock by
reason of a stock dividend, stock split, split up, recapitalization,
combination, exchange of shares or similar transaction, such that Comerica will
receive (upon exercise of the option) the same number and type of securities as
if the option had been exercised immediately prior to the occurrence of such
event (or the record date therefor). The number of shares of UBT Common Stock
subject to the option will also be adjusted in the event that UBT issues
additional shares of common stock such that the number of shares of common stock
subject to the option, together with shares previously purchased pursuant
thereto, represents 9.9% of UBT's Common Stock then issued and outstanding,
without giving effect to shares subject to or issued pursuant to the option.
 
     In the event that UBT enters into any agreement (i) to merge or consolidate
with any person other than Comerica or one of its subsidiaries such that UBT is
not the surviving corporation, (ii) to permit any person, other than Comerica or
one of its subsidiaries, to merge into UBT and UBT is the surviving corporation,
but, in connection with such merger, the outstanding shares of UBT's Common
Stock are changed into or exchanged for stock or other securities of UBT or any
other person or cash or any other property or the outstanding shares of UBT's
Common Stock prior to such merger shall after such merger represent less than
50% of the outstanding shares and share equivalents of the merged company, or
(iii) to sell or otherwise
 
                                       63
<PAGE>   71
 
transfer all or substantially all of its assets to any person other than
Comerica or one of its subsidiaries, then, and in each such case, the agreement
governing the transaction must provide that, upon consummation of the
transaction, the option will be converted into or exchanged for an option (the
"Substitute Option") to purchase securities of either the acquiring person, a
person that controls the acquiring person or UBT (if UBT is the surviving
entity), in all cases in the option of Comerica. The number of shares for which
the Substitute Option will be exercisable and the exercise price applicable
thereto will be determined in accordance with Sections 7(c) and 7(d) of the
Stock Option Agreement.
 
     As described above under "Stock Option Agreement," the Stock Option
Agreement may discourage competing offers for UBT and is intended to increase
the likelihood that the Merger is consummated in accordance with the terms of
the Merger Agreement.
 
                                 LEGAL MATTERS
 
     The legality of the Comerica Common Stock and associated rights to be
issued in connection with the Merger will be passed upon by Miller, Canfield,
Paddock and Stone, P.L.C., 150 West Jefferson, Suite 2500, Detroit, Michigan
48226.

this Agreement, as promptly as practicable following the receipt of the Last
Regulatory Approval and the expiration of all applicable waiting periods,
INTERIM shall be merged into UBT (which shall be the Surviving Corporation of
the merger) in accordance with the applicable provisions of the California
Financial Code and the California Corporations Code (the "Merger") pursuant to
the Agreement of Merger attached to this Agreement as Exhibit 2.1 (the

shall take place at a location, time and Business Day to be designated by
COMERICA (the "Closing Date").  The Merger shall be effective when the

to effectuate the Merger) shall have been approved by the Superintendent of
Banks and filed with the Secretary of State of the State of California.  When
used in this Agreement, the term "Effective Time" shall mean the time of filing
of the Subsidiary Merger Agreement with the Secretary of State, and "Surviving
Corporation" shall mean UBT.

         Section 2.2      Effect of the Merger. By virtue of the Merger and at
the Effective Time, all of the rights, privileges, powers and franchises and
all property and assets of every kind and description of UBT and INTERIM shall
be vested in and be held and enjoyed by the Surviving Corporation, without
further act or deed, and all the estates and interests of every kind of UBT and
INTERIM, including all debts due to either of them, shall be as effectively the
property of the Surviving Corporation as they were of UBT and INTERIM
immediately prior to the Effective Time, and the title to any real estate
vested by deed or otherwise in either UBT or INTERIM shall not revert or be in
any way impaired by reason of the Merger; and all rights of creditors and liens
upon any property of UBT and INTERIM shall be preserved unimpaired and all
debts, liabilities and duties of UBT and INTERIM shall be debts, liabilities

                                       8
<PAGE>   85
enforced against it to the same extent as if such debts, liabilities and duties
had been incurred or contracted by it, and none of such debts, liabilities or
duties shall be expanded, increased, broadened or enlarged by reason of the
Merger.

         Section 2.3      Articles of Incorporation. The articles of
incorporation of INTERIM in effect immediately prior to the Effective Time
shall be the articles of incorporation of the Surviving Corporation until
amended in accordance with the provisions thereof and the name of the Surviving
Corporation shall be "University Bank & Trust Company."

         Section 2.4      Conversion of INTERIM Stock.  The authorized and
issued capital stock of INTERIM, all of which shall be owned by COMERICA,
immediately prior to the Effective Time, on and after the Effective Time,
pursuant to the Subsidiary Merger Agreement and without any further action on
the part of COMERICA or INTERIM shall be converted into one share of common
stock of the Surviving Corporation (the "Surviving Corporation Stock").  Each
outstanding stock certificate which prior to the Effective Time represented
shares of capital stock of INTERIM automatically and for all purposes shall be
deemed to represent the number of shares of Surviving Corporation Stock into
which the shares of capital stock of INTERIM represented by such certificate
have been converted as provided in this Section 2.4.

         Section 2.5      Conversion of UBT Stock Options. At the Effective
Time, all outstanding rights with respect to UBT Common Stock pursuant to stock
options under the UBT Stock Option Plans, whether vested or unvested or whether
or not then exercisable, shall be converted into and become rights with respect
to COMERICA Common Stock, and COMERICA shall assume each UBT Stock Option  in
accordance with the terms of the UBT Stock Option Plans and the stock option
agreement by which it is evidenced.

                          2.5.1  From and after the Effective Time, (i) each
UBT Stock Option assumed by COMERICA may be exercised solely for shares of
COMERICA Common Stock; (ii) the number of shares of COMERICA Common Stock
subject to each UBT Stock Option shall be equal to the number of full or
partial shares of COMERICA Common Stock as the holder of such UBT Stock Option
would have been entitled to receive pursuant to Section 2.6 of this Agreement
had such holder exercised such option in full immediately prior to the
Effective Time (the "Deemed COMERICA Shares"); and (iii) the per share exercise
price for each such UBT Stock Option shall be equal to the result of (y) the
aggregate exercise price for the shares of UBT Common Stock otherwise
purchasable pursuant to such UBT Stock Option, divided by (z) the Deemed
COMERICA Shares; provided, however, that the option price, the number of shares
purchasable pursuant to such option and the terms and conditions of exercise of
such option shall be determined in order to comply with Section 424(a) of the
IRC.

                          2.5.2  As soon as practicable after the Effective
Time, COMERICA shall file a registration statement on Form S-3 or Form S-8, as
the case may be (or any successor or other appropriate forms), or another
appropriate form with respect to the shares of COMERICA Common





                                       9
<PAGE>   86
Stock subject to such options and shall use its best efforts to maintain the
effectiveness of such registration statements for so long as such options
remain outstanding.

         Section 2.6      Conversion of Issued and Outstanding UBT Common
Stock.   Except as provided in Section 2.7, each share of Fully Diluted UBT
Common Stock shall be converted at the Effective Time into and become the right
to receive that number of shares of duly authorized, validly issued, fully paid
and nonassessable shares of COMERICA Common Stock equal to the Conversion Rate,
as determined at the Effective Time, subject to adjustment, if any, as provided
in any other section of this Agreement.  The Conversion Rate shall be further
appropriately adjusted to reflect any recapitalization, reorganization,
reclassification, split-up, merger, consolidation, exchange, stock or other
dividend or distribution (other than regular quarterly cash dividends), made,
declared or effective with respect to the COMERICA Common Stock between the
date of this Agreement and the Effective Time.


         Section 2.7      Fractional Shares.  No fractional shares of
COMERICA Common Stock shall be issued in the Merger.  In lieu thereof, each
holder of UBT Common Stock who would otherwise be entitled to receive a
fractional share shall receive an amount in cash equal to the product (rounded
to the nearest tenth) obtained by multiplying (a) the Agreement Date COMERICA
Share Price by (b) the fraction of the share of COMERICA Common 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.

         Section 2.8      Exchange Procedures.  On or as soon as practicable
after the Effective Time, COMERICA will deliver to the Exchange Agent
certificates representing a sufficient number of shares of COMERICA Common
Stock issuable in the Merger and funds representing a sufficient amount of cash
payable for fractional shares in the Merger pursuant to Section 2.7 of this
Agreement.

                          2.8.1   Upon surrender for cancellation to the
Exchange Agent of one or more certificates for shares of UBT Common Stock ("UBT
Certificates"), accompanied by a duly executed letter of transmittal in proper
form, the Exchange Agent shall, as promptly as practicable thereafter, deliver
to each holder of such surrendered UBT Certificates, certificates representing
the appropriate number of shares of COMERICA Common Stock ("New Certificates")
and/or checks for payment of cash in lieu of fractional shares, in respect of
the UBT Certificates. In no event shall the holders of UBT Certificates
entitled to receive cash in lieu of fractional shares be entitled to receive
interest on such amounts.

                          2.8.2   Until the UBT Certificates have been
surrendered and exchanged as herein provided, each outstanding UBT Certificate
shall represent, on and after the Effective Time, the right to receive the
number of shares of COMERICA Common Stock into which the number of shares of
UBT Common Stock shown thereon have been converted as provided by Section 2.6.
No dividends or other distributions that are declared on COMERICA Common Stock
shall be paid to holders thereof otherwise entitled to receive the same until
the UBT Certificates have been





                                       10
<PAGE>   87
surrendered in exchange for New Certificates in the manner herein provided, but
upon such surrender, such dividends or other distributions, from and after the
Effective Time, will be paid to such holders in accordance with the terms of
such COMERICA Common Stock. In no event shall the holders entitled to receive
such dividends or other distributions be entitled to receive interest on such
dividends or other distributions.

                          2.8.3   No transfer taxes shall be payable by any
shareholder in respect of the issuance of New Certificates, except that if any
New Certificate is to be issued in a name other than that in which the UBT
Certificates surrendered shall have been registered, it shall be a condition of
such issuance that the holder requesting such issuance shall properly endorse
the certificate or certificates and shall pay to COMERICA or the Exchange Agent
any transfer taxes payable by reason thereof, or of any prior transfer of such
surrendered certificate, or establish to the satisfaction of COMERICA or the
Exchange Agent that such taxes have been paid or are not payable.

                          2.8.4   Any COMERICA Common Stock or cash delivered
to the Exchange Agent (together with any interest or profits earned thereon)
and not distributed pursuant to this Section 2.8 at the end of nine months from
the Effective Time, shall be returned to COMERICA, in which event the Persons
entitled thereto shall look only to COMERICA for payment thereof.

                          2.8.5   Notwithstanding anything to the contrary set
forth in Sections 2.8.2 and 2.8.3 hereof, if any holder of UBT Common Stock
shall be unable to surrender such holder's UBT Certificates because such
certificates have been stolen, lost or destroyed, such holder may deliver in
lieu thereof an affidavit and indemnity bond in form and substance and with
surety reasonably satisfactory to Exchange Agent and COMERICA.

                          2.8.6   The Exchange Agent shall not be entitled to
vote or exercise any rights of ownership with respect to the shares of COMERICA
Common Stock held by it from time to time hereunder, except that it shall
receive and hold all dividends or other distributions paid or distributed with
respect to such shares of COMERICA Common Stock for the account of the Persons
entitled thereto.

                          2.8.7   After the Effective Time, there shall be no
further registration of transfers on the stock transfer books of the Surviving
Corporation of the shares of UBT Common Stock which were outstanding
immediately prior to the Effective Time.  If, after the Effective Time,
certificates representing such shares are presented to the Surviving
Corporation, they shall be canceled and exchanged for COMERICA Common Stock as
provided in this Article 2.

permits that are necessary for the conduct of their respective businesses, and

constitutes a valid and binding obligation of UBT, enforceable in accordance
with its terms, except as the enforceability thereof may be limited by

of California state banks, and in any case, by general equitable principles,

other similar laws affecting the rights of California banks generally and by
general equitable principles.

                          3.4.2   Except as disclosed on Schedule 3.4, the
execution and delivery of this Agreement and the Subsidiary Merger Agreement
and the consummation of the transactions contemplated hereby and thereby do not

<PAGE>   89
default or loss of a material benefit under, any provision of the articles of
incorporation or bylaws of UBT or, except for the necessity of obtaining
Requisite Regulatory Approvals and approval of the shareholders of UBT, any
material mortgage, indenture, lease, agreement or other instrument or any
permit, concession, grant, franchise, license, judgment, order, decree,
statute, law, ordinance, rule or regulation applicable to UBT or its
properties, other than any such conflict, violation, default or loss which will
not have a Material Adverse Effect on UBT or which will be cured or waived
prior to the Effective Time.  No material consent, approval, order or
authorization of, or registration, declaration or filing with, any governmental
authority is required in connection with the execution and delivery of this
Agreement or the Subsidiary Merger Agreement by UBT or the consummation by it
of the transactions contemplated hereby or thereby, except for (a) filings

rights.  Other than the UBT Stock Options described on Schedule 3.27 to this
Agreement and the Stock Option Agreement, there are not on the date of this
Agreement any options, warrants, calls, rights, commitments, securities or
agreements of any character to which UBT is a party or by which it is bound
obligating UBT to issue, deliver or sell, or cause to be issued, delivered or
sold, additional shares of capital stock of UBT or obligating UBT to grant,
extend or enter into any such option, warrant, call, right, commitment or
agreement.

                          3.5.2   UBT is the direct owner, beneficially and of
record, of all of the issued and outstanding capital stock of the Lytton
Corporation which is its only direct Subsidiary, free and clear of all liens,
pledges, charges and other encumbrances of any nature whatsoever.

         Section 3.6      UBT Filings.

                          3.6.1   Since January 1, 1992, UBT and its
Subsidiaries have filed all reports, registrations and statements, together
with any amendments required to be made with respect thereto, copies of which

that were required to be filed with (a) the Federal Reserve Board or any
Federal Reserve Bank; (b) the California Superintendent of Banks; (c) the
Federal Deposit Insurance Corporation; and (d) any other applicable federal,
state or local governmental or regulatory authority. All such reports,





                                       13
<PAGE>   90
registrations and filings are collectively referred to as the "UBT Filings."
As of their respective filing dates, each of the past UBT Filings (a) was true
and complete in all material respects (or was amended so as to be so promptly
following discovery of any discrepancy); and (b) complied in all material
respects with all of the statutes, rules and regulations enforced or
promulgated by the Governmental Entity with which it was filed (or was amended
so as to be so promptly following discovery of any such noncompliance) and none
contained any untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading.   The UBT Financial Statements have been prepared in accordance
with Generally Accepted Accounting Principles or applicable banking regulations
applied on a consistent basis during the periods involved (except as may be
indicated in the notes thereto) and present fairly (subject, in the case of the
unaudited statements, to recurring adjustments normal in nature and amount) the
consolidated financial position of UBT as of the respective dates indicated and
the consolidated results of its operations and changes in cash flows at the
respective dates and for the respective periods covered by such financial
statements.

                          3.6.2   UBT has filed each report, schedule,
registration statement and definitive proxy statement and amendments to each of
the foregoing since January 1, 1991 that UBT was required to file with the SEC,
the OCC or the FDIC, as applicable, since such date (the "UBT SEC Documents"),
all of which have been made available to COMERICA.  As of their respective
dates, the UBT SEC Documents complied in all material respects with the
requirements of the Securities Act and the Exchange Act, as the case may be,
and the rules and regulations of the SEC thereunder applicable to such UBT SEC
Documents, and none of the UBT SEC Documents contained any untrue statement of
a material fact or omitted to state a material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.  The financial
statements of UBT included in the UBT SEC Documents comply in all material
respects with applicable accounting requirements and with the published rules
and regulations of the SEC with respect thereto, have been prepared in
accordance with Generally Accepted Accounting Principles applied on a
consistent basis during the periods involved (except as may be indicated in the
notes thereto or, in the case of the unaudited statements, as permitted by Form
10-Q of the SEC) and fairly present (subject, in the case of the unaudited
statements, to recurring audit adjustments normal in nature and amount) the
consolidated financial position of UBT as at the dates thereof and the

         Section 3.8      Compliance with Applicable Laws. The businesses of
UBT and its Subsidiaries are not being conducted in violation of any applicable
law, ordinance or regulation, except for violations which individually or in
the aggregate would not have a Material Adverse Effect on UBT.  Except as set
forth in Schedule 3.8 and except for normal examinations conducted by a
Governmental Entity in the regular course of business of UBT, no investigation
or review by any Governmental Entity with respect to UBT is pending or, to the
knowledge of UBT, threatened, nor has any Governmental Entity indicated to UBT
an intention to conduct the same, other than those the outcome of which, as far
as can be reasonably foreseen, will not have a Material Adverse Effect on UBT.

         Section 3.9      Litigation. There is no suit, action or proceeding
pending or, to the knowledge of UBT, threatened against or affecting UBT or any
Subsidiary which, if adversely determined, would have a Material Adverse Effect
on UBT and its Subsidiaries taken as a whole; nor is there any judgment,
decree, injunction, rule or order of any Governmental Entity or arbitrator
outstanding against UBT or any Subsidiary having, or which, insofar as
reasonably can be foreseen, in the future would have, any such effect.
Schedule 3.9 contains a true, correct and complete list, including
identification of the applicable insurance policy covering such litigation, if
any, subject to reservation of rights, if any, the applicable deductible and
the amount of any reserve therefor, of all pending litigation in which UBT or
any Subsidiary is a named party, all of which is adequately covered by
insurance in force, except for applicable deductibles, or have been adequately
reserved for in accordance with UBT's and UBT's prior business practices.

         Section 3.10     Agreements with Banking Authorities. Except as set

is a party to any written agreement, memorandum of understanding, order or
directive with any Governmental Entity.

         Section 3.11     Insurance. Schedule 3.11 contains a list of all
policies of insurance and bonds carried and owned by UBT or any Subsidiary.
None of UBT or any Subsidiary is in default under any such policy of insurance
or bond such that it can be canceled and all material claims thereunder have
been filed in timely fashion. UBT and its Subsidiaries have filed claims with,
or given notice of claim, to their insurers or bonding companies in timely
fashion, with respect to all material matters and occurrences for which they
believe they have coverage.

         Section 3.12     Title to Assets other than Real Property. UBT and its
Subsidiaries have good and marketable title to all their properties and assets,
other than real property which is the subject of Section 3.13, owned or leased
by UBT or any Subsidiary, free and clear of all mortgages, liens, encumbrances,
pledges or charges of any kind or nature except for: (a) encumbrances as set
forth in the UBT Financial Statements; (b) liens for current taxes not yet due
which have been fully reserved for; and (c) encumbrances, if any, that are not
substantial in character, amount or extent or that do not materially detract
from the value, or materially interfere with present use of the property
subject thereto or affected thereby.

         Section 3.13     Real Property. Schedule 3.13 is an accurate list and
general description of all real property owned or leased by UBT or any of its
Subsidiaries other than Other Real Estate Owned.  UBT and its Subsidiaries have
good and marketable title to the real property, and valid leasehold interests
in the leaseholds, described in such schedule, free and clear of all mortgages,
covenants, conditions, restrictions, easements, liens, security interests,

and (d)  encumbrances, if any, that are not substantial in character, amount or
extent or that do not materially detract from the value, or materially
interfere with present use of the property subject thereto of affected thereby;
and (e) minor defects and irregularities in title and encumbrances which do not
materially impair the use thereof for the purposes for which such property is
held. UBT and its Subsidiaries have valid leasehold interests in the leaseholds
they respectively hold, free and clear of all mortgages, liens, security
interest, charges, claims, assessments and encumbrances, except for (a) claims
of lessors, co-lessees or sublessees in such matters as are reflected in a
written lease; (b) title exceptions affecting the fee estate of the lessor
under such leases and (c) other matters as described in Schedule 3.13.  The
activities of UBT  and its Subsidiaries with respect to all real property owned
or leased by them for use in connection with their operations are in all
material respects permitted and authorized by applicable zoning laws,
ordinances and regulations and all applicable laws and regulations of any
Governmental Entity, including environmental matters affecting such properties.
Except as set forth in Schedule 3.13, UBT and its Subsidiaries enjoy quiet
possession under all material leases to which either is the lessee and all of
such leases are valid and in full force and effect.

         Section 3.14     Taxes.

                          3.14.1  Filing of Returns.  UBT and its Subsidiaries
have duly prepared and filed federal, state, local and foreign Returns (for tax
or informational purposes) which were required to be filed by or in respect of
UBT and its Subsidiaries, or any of their properties, income and/or operations
on or prior to the Closing Date.  As of the time of filing, the foregoing
Returns correctly reflect the material facts regarding the income, business,
assets, operations, activities, status, and any other information required to
be shown thereon.  Except as set forth on Schedule 3.14, no extension of time
within which to file any Return has been requested.

                          3.14.2  Payment of Taxes.  With respect to all Taxes
imposed on UBT or any Subsidiary or for which UBT is or could be liable,
whether to taxing authorities (as, for example, under law) or to other Persons
or entities (as, for example, under tax allocation agreements), with respect to
all taxable periods or portions of periods ending on or before the Closing
Date, all applicable tax laws and agreements have been or will be fully
complied with, and all such amounts required to be paid by or on behalf of UBT
or any Subsidiary to taxing authorities or others on or before the date hereof
have been paid.

                          3.14.3  Audit History.   Except as disclosed on

                                       17
<PAGE>   94
or any Subsidiary.  Except as disclosed on Schedule 3.14, UBT and its
Subsidiaries have not received any notice of any pending or threatened audit by
the Internal Revenue Service or any state, local or foreign agency related to
UBT's and its Subsidiaries' Tax or information returns or Tax liability for any
period and no claim for assessment or collection of Taxes has been asserted
against UBT or its Subsidiaries.  UBT and its Subsidiaries currently have no
unpaid deficiency assessed by the Internal Revenue Service or any state, local
or foreign taxing authority with respect to any of UBT's and its Subsidiaries'
Tax returns filed for fiscal years ended on or after December 31, 1987 through
Closing Date, nor, to the Knowledge of UBT, is there reason to believe that any
deficiency will be assessed.  There are no actions, suits, proceedings,
investigations or claims now pending or, to the Knowledge of UBT, threatened
against UBT or its Subsidiaries in respect of Taxes, nor are any matters under
discussion by UBT or its Subsidiaries with any Governmental Entity relating to
Taxes.

                          3.14.4  Statute of Limitations.  No agreements are in
force or are currently being negotiated by or on behalf of UBT or its
Subsidiaries for any waiver or for the extension of any statute of limitations
governing the time of assessment or collection of any Tax.  No closing
agreements or compromises with any taxing authority are currently pending or
have been entered into by UBT or its Subsidiaries.

                          3.14.5  Withholding Obligations.  UBT and its
Subsidiaries have withheld from each payment made to any of its officers,
directors and employees, the amount of all applicable Taxes, including, but not
limited to, income tax, social security contributions, unemployment
contributions, backup withholding and other deductions required to be withheld
therefrom by any Tax law and have paid the same to the proper Taxing
authorities within the time required under any applicable legislation.

                          3.14.6  Tax Liens.  There are no Tax liens, whether
imposed by any federal, state, local or foreign taxing authority, outstanding
against any assets owned by UBT or its Subsidiaries, except for liens for taxes
that are not yet due and payable.

                          3.14.7  Safe Harbor Lease Property.  None of the
assets owned by UBT or its Subsidiaries is property that is required to be
treated as being owned by any other Person pursuant to the so-called safe
harbor lease provisions of former Section 168 (f)(8) of the IRC.

                          3.14.8  Security for Tax-Exempt Obligations.  None of
the assets owned by UBT or its Subsidiaries directly or indirectly secures any
debt, the interest on which is tax-exempt under Section 103(a) of the IRC.

                          3.14.9  Tax-Exempt Use Property.  None of the assets
owned by UBT or its Subsidiaries is "tax-exempt use property" within the
meaning of Section 168(h) of the IRC.

                          3.14.10 Foreign Person.  None of UBT or its
Subsidiaries is a person other than a United States person within the meaning
of the IRC.

<PAGE>   95
                          3.14.11 No Withholding.  The transaction contemplated
herein is not subject to the tax withholding provisions of Section 3406 of the
IRC, or of Subchapter A of Chapter 3 of the IRC.

                          3.14.12 Tax Reserves.  UBT and its Subsidiaries have
made full and adequate provision and reserve for all federal, state, local or
foreign Taxes for the current period for which Tax and information returns are
not yet required to be filed.  The UBT Financial Statements contain fair and
sufficient accruals for the payment of all Taxes for the periods covered by the
UBT Financial Statements and all periods prior thereto.

                          3.14.13 Tax Elections.  No new material elections
with respect to Taxes or any changes in current material elections with respect
to Taxes affecting the assets owned by UBT or its Subsidiaries shall be made
after the date of this Agreement without the prior written consent of COMERICA,
which shall not be unreasonably withheld.

                          3.14.14 IRC Section 382 Applicability.  None of UBT
or any related party, including any party joining in any consolidated return to
which UBT is a member, was subject to IRC Section  382 prior to the execution
of this Agreement.

                          3.14.15 Disclosure Information.  Within sixty days of
the date of this Agreement, UBT will provide COMERICA with a schedule setting
forth the following information with respect to UBT as of the most recent
practicable date: (a) UBT's basis in its assets; (b) the amount of any net
operating loss, net capital loss, unused investment or other credit, unused
foreign tax, or excess charitable contribution allocable to UBT; and (c) the
amount of any deferred gain or loss allocable to UBT arising out of any
deferred intercompany transactions.

         Section 3.15     Performance of Obligations. UBT and its Subsidiaries
have performed in all material respects all of the obligations required to be
performed by them to date under, and none of UBT nor any Subsidiary is in
default under or in breach of, any term or provision of any covenant, contract,
lease, indenture or any other covenant to which any is a party, is subject or
is otherwise bound, and no event has occurred that, with the giving of notice
or the passage of time or both, would constitute such default or breach, where
such default or breach or failure to perform would have a Material Adverse
Effect on UBT and its Subsidiaries taken as a whole.  To UBT's Knowledge no
party with whom UBT or its Subsidiaries has an agreement that is of material
importance to the businesses of UBT and its Subsidiaries taken as a whole is in
default thereunder.

         Section 3.16     Loans and Investments. Except as set forth on
Schedule 3.16, in all material respects, all loans, leases and other extensions
of credit, and guaranties, security agreements or other agreements supporting
any loans or extensions of credit, and investments of UBT and its Subsidiaries
are, and constitute the legal, valid and binding obligations of the parties
thereto and are enforceable against such parties in accordance with their
terms, except as the enforceability thereof may be limited by bankruptcy,
insolvency, moratorium or other similar laws affecting the rights of California
banks or creditors generally and by general equitable principles.  As of August
31, 1994, and except as





                                       19
<PAGE>   96
disclosed in Schedule 3.16, no loans or investments held by UBT or any
Subsidiary are (i) more than ninety days past due with respect to any scheduled
payment of principal or interest, other than loans on a non-accrual status;
(ii) classified as "loss," "doubtful," "substandard" or "specially mentioned"
by any federal or state banking regulators; or (iii) on a non-accrual status in
accordance with UBT's loan review procedures.  None of such investments, other
than loans, are subject to any restrictions, contractual, statutory or other,
that would materially impair the ability of the entity holding such investment
to dispose freely of any such investment at any time, except restrictions on
the public distribution or transfer of any such investments under the
Securities Act and the regulations thereunder or state securities laws and
pledges or security interests given in connection with government deposits.
UBT has no loans, leases or other extensions of credit outstanding, or
commitments to make any loans, leases or other extensions of credit to any
Affiliates of UBT which are not on substantially the same terms (including
interest rates, repayment terms and collateral) as would be available for
comparable transactions with Persons of similar creditworthiness who are not
Affiliates of UBT. For each outstanding loan or extension of credit or
commitment to make a loan or extension of credit where the original principal
amount is in excess of $25,000, UBT to its Knowledge has taken all action
consistent with good banking practice to document each such loan or extension
of credit, including perfecting security interests, if applicable, or obtaining
the due execution and delivery of guaranties or similar obligations, if
applicable.

         Section 3.17     Status of Trust Assets. Schedule 3.17 is a complete
list of all Trust Assets.

                          3.17.1  With respect to the Trust Assets:  (i) no
notice has been received by UBT or any of its Subsidiaries questioning the
validity or enforceability of any of the agreements, contracts or other
commitments to which UBT is a party comprising a part of the Trust Assets; (ii)
to UBT's Knowledge, none of the parties to any such agreement, contract or
other commitment is in default of any material obligation under, or in the
performance of, any material term, condition or other provision of any such
agreement, contract or other commitment; (iii) the rights of UBT or its
Subsidiaries to receive fees in connection with Trust Assets are free and clear
of all pledges, security interests and liens of any kind whatsoever; (iv) in
the management, operation and servicing of the Trust Assets, UBT and its
Subsidiaries have complied, in all material respects, with all applicable
federal, state and local laws, rules, regulations, ordinances, rulings, orders,
awards, judgments and decrees; and (v) in the management, operation and
servicing of the Trust Assets, UBT and its Subsidiaries have complied with all
material terms of all instruments governing the Trust Assets.

                          3.17.2  Except as set forth on Schedule 3.17.2, to
UBT's Knowledge, (without conducting any site investigation or other analysis
for the purpose of making this representation), neither the use nor current
condition of any real property relating to the Trust Assets is or has been such
during the time the Trust Assets were owned, operated or managed by UBT, in
violation of any Environmental Law under circumstances where the violation
would have a Material Adverse Effect (as defined in Section 5.7.2) on the real
property in question.  UBT has adhered to and followed in all material respects
all environmental policies of UBT with respect to the Trust Assets.

         Section 3.18     Brokers and Finders.  Other than the retention of
Goldman, Sachs & Co., none of UBT or any Subsidiary is a party to or obligated
under any agreement with any broker or finder relating to the transactions
contemplated hereby, and neither the execution of this Agreement or the
Subsidiary Merger Agreement nor the consummation of the transactions provided
for herein or therein will result in any liability to any broker or finder.
UBT agrees to indemnify and hold  harmless COMERICA and INTERIM and their
respective affiliates, and to defend with counsel selected by COMERICA and
INTERIM and reasonably satisfactory to UBT from and against any liability, cost
or expense, including reasonable attorneys' fees, incurred in connection with a
breach of this Section 3.18.

         Section 3.19     Material Contracts. Schedule 3.19 to this Agreement
is a complete and accurate written list of all material agreements, obligations
or understandings, written and oral, to which UBT or any Subsidiary is a party
as of the date of this Agreement, except for loans and other extensions of
credit made by UBT in the ordinary course of business and those items disclosed
in the UBT Financial Statements.

         Section 3.20     Absence of Material Adverse Effect. Since December
31, 1993, the businesses of UBT and its Subsidiaries have been conducted only
in the ordinary course, in the same manner as theretofore conducted, and no
event or circumstance occurred or is expected to occur which has, or is likely
to result in,  a Material Adverse Effect on UBT.

         Section 3.21     Undisclosed Liabilities. To UBT's Knowledge, UBT and
its Subsidiaries have no liabilities or obligations, either accrued, contingent
or otherwise, that are material to UBT and its Subsidiaries taken as a whole
and that have not been reflected or disclosed in the UBT Financial Statements,
or incurred subsequent to December 31, 1993 in the ordinary course of business
consistent with past practices.  Neither UBT nor any of UBT's Subsidiaries has
any knowledge of any basis for the assertion against any of them of any
liability, obligation or claim (including without limitation that of any
Governmental Entity) that is likely to result in or cause a Material Adverse
Effect that is not fairly reflected in the UBT Financial Statements.

         Section 3.22     Employees; Employee Benefit Plans; ERISA.

                          3.22.1  All of UBT's and its Subsidiaries'
obligations for payment to trusts or other funds or to any Governmental Entity
or to any individual, director, officer, employee or agent (or his or her
heirs, legatees or legal representatives) with respect to unemployment
compensation benefits, profit-sharing, pension or retirement benefits or social
security benefits, whether arising by operation of law, by contract or by past
custom, have been properly accrued for the periods covered thereby on the UBT
Financial Statements and paid when due.  All of UBT's and its Subsidiaries
obligations, whether arising by operation of law, by contract or by past custom
for vacation or holiday pay, bonuses and other forms of compensation which are
payable to UBT's and its Subsidiaries' directors, officers, employees or agents
have been properly accrued on the UBT Financial Statements for the periods
covered thereby and paid when due.  Except as set forth on Schedule 3.22, there
are no unfair labor practice complaints, strikes, slowdowns, stoppages or other
controversies pending





                                       21
<PAGE>   98
or, to the knowledge of UBT, attempts to unionize or controversies threatened
between UBT or any Subsidiary or Affiliate and, or relating to, any of their
employees that are likely to have a Material Adverse Effect on UBT and its
Subsidiaries taken as a whole.  None of UBT or any Subsidiary is a party to any
collective bargaining agreement with respect to any of their employees and,
except as set forth on Schedule 3.22, none of UBT or any Subsidiary is a party
to a written employment contract with any of their employees and there are no
understandings with respect to the employment of any officer or employee of UBT
or its Subsidiaries which are not terminable by UBT or its Subsidiaries without
liability on not more than thirty (30) days' notice.  Except as disclosed in
the UBT Financial Statements for the periods covered thereby, all sums due for
employee compensation have been paid and all employer contributions for
employee benefits, including deferred compensation obligations, and any
benefits under any Employee Plan (as defined in Section 3.22.3 hereof) or any
Benefit Arrangement (as defined in Section 3.22.4 hereof) have been duly and
adequately paid or provided for in accordance with plan documents.  Except as
set forth on Schedule 3.22, no director, officer or employee of UBT or any
Subsidiary is entitled to receive any payment of any amount under any existing
agreement, severance plan or other benefit plan as a result of the consummation
of any transaction contemplated by this Agreement or the Subsidiary Merger
Agreement.  UBT and its Subsidiaries have complied in all material respects
with all applicable federal and state statutes and regulations which govern
workers' compensation, equal employment opportunity and equal pay, including,
but not limited to, all civil rights laws, Presidential Executive Order 1124,
and the Fair Labor Standards Act of 1938, as amended and the Americans with
Disabilities Act.

                          3.22.2  Prior to the execution of this Agreement, 
UBT has delivered as Schedule 3.22 a complete list of:

                                  a.       all current employees of UBT or any
Subsidiary, together with each employee's age, tenure with UBT or Subsidiary,
title or job classification, and the current annual rate of compensation
anticipated to be paid to each such employee; and

                                  b.       all Employee Plans and Benefit
Arrangements, including all plans or practices providing for current
compensation or accruals for active Employees, including, but not limited to,
all employee benefit plans, all pension, profit-sharing, retirement, bonus,
stock option, incentive, deferred compensation, severance, long-term
disability, medical, dental, health, hospitalization, life insurance or other
insurance plans or related benefits.

                          3.22.3  Except as disclosed on Schedule 3.22, none of
UBT or any Subsidiary maintains, administers or otherwise contributes to any
"employee benefit plan," as defined in Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), which is subject to any
provisions of ERISA and covers any employee, whether active or retired, of UBT
or any Subsidiary of either (any such plan being herein referred to as an
"Employee Plan").  True and complete copies of each such Employee Plan,
including amendments thereto, have been previously delivered to COMERICA,
together with (i) all agreements regarding plan assets with respect to such
Employee Plans, (ii) a true and complete copy of the annual reports for the

and B thereto) prepared in connection with

any such Employee Plan, (iii) a true and complete copy of the actuarial
valuation reports for the most recent three years, if any, prepared in
connection with any such Employee Plan covering any active employee of UBT,
(iv) a copy of the most recent summary plan description of each such Employee
Plan, together with any modifications thereto, and (v) a copy of the most
recent favorable determination letter (if applicable) from the Internal Revenue
Service for each Employee Plan.  None of the Employee Plans is a "multiemployer
plan" as defined in Section 3(37) of ERISA or a "multiple employer plan" as
covered in Section 412(c) of the IRC, and none of UBT or any Subsidiary has
been obligated to make a contribution to any such multiemployer or multiple
employer plan within the past five years.  Each Employee Plan which is intended
to be qualified under Section 401(a) of the IRC is so qualified and each trust
maintained pursuant thereto is exempt from income tax under Section 501(a) of
the IRC, and none of UBT or any Subsidiary is aware of any fact which has
occurred which would cause the loss of such qualification or exemption.

                          3.22.4  Except as disclosed in Schedule 3.22 and
exclusive of any Employee Plan, none of UBT or any Subsidiary maintains (other
than base-salary and base wages) any form of current or deferred compensation,
bonus, stock option, stock appreciation right, severance pay, salary
continuation, retirement or incentive plan or arrangement for the benefit of
any director, officer or employee, whether active or retired, of UBT or any
Subsidiary or for any class or classes of such directors, officers or
employees.  Except as disclosed in Schedule 3.22 and other than any Employee
Plan, none of UBT or any Subsidiary maintains any group or individual health or
insurance, welfare or similar plan or arrangement for the benefit of any
director, officer or employee of UBT or any Subsidiary whether active or
retired, or for any class or classes of such directors, officers or employees.
Any such plan or arrangement described in this Section 3.22.4, copies of which
have been delivered to COMERICA, shall be herein referred to as a "Benefit
Arrangement."

                          3.22.5  All Employee Plans and Benefit Arrangements
are operated in material compliance with the requirements prescribed by any and
all statutes, governmental or court orders, or governmental rules or
regulations currently in effect, including but not limited to ERISA and the
IRC, applicable to such plans or arrangements, and plan documents relating to
any such plans or arrangements, comply with or will be amended to comply with
applicable legal requirements.  Except as disclosed in Schedule 3.22, no
Employee Plan which is subject to Title IV of ERISA has been completely or
partially terminated and no condition exists that could constitute grounds for
the termination of any Employee Plan pursuant to Subtitle C of Title IV of
ERISA, nor has UBT or any Subsidiary incurred, nor does either reasonably
expect to incur, any liability to the Pension Benefit Guaranty Corporation,
except for required premium payments which have been paid when due; except as
disclosed in Schedule 3.22, none of the Employee Plans which are employee
pension benefit plans within the meaning of Section 3(2) of ERISA has engaged
in a merger or consolidation with any other plan or transferred assets or
liabilities from any other plan; with respect to each Employee Plan, to UBT's
Knowledge, none of UBT, any Subsidiary nor any Employee Plan, nor any trusts
created thereunder, nor any trustee, administrator nor any other fiduciary
thereof, has engaged in a "prohibited transaction," as defined in Section 406
of ERISA and Section 4975 of the IRC, that could subject any of them or
COMERICA to liability under Section 409 or 502(i) of ERISA or Section 4975 of
the IRC or that would adversely affect the qualified status of such plans; each
"plan official"





                                       23
<PAGE>   100
within the meaning of Section 412 of ERISA of each Employee Plan is bonded to
the extent required by such Section 412; with respect to each Employee Plan, to
the Knowledge of UBT, no employee of UBT or any Subsidiary nor any fiduciary of
any Employee Plan has engaged in any breach of fiduciary duty as defined in
Part 4 of Subtitle B of Title I of ERISA which could subject UBT or any
Subsidiary to liability if UBT or any Subsidiary is obligated to indemnify such
Person against liability.  No Employee Plan that is subject to Title IV of
ERISA or Section 412 of the IRC incurred any "accumulated funding deficiency"
(as defined in ERISA), whether or not waived, taking into account contributions
made within the period described in Section 412(c)(10) of the IRC; nor, except
as disclosed in Schedule 3.22, has any of UBT or any Subsidiary failed to make
any contribution or pay any amount due and owing as required by law or the
terms of any Employee Plan or Benefit Arrangement.

                          3.22.6  Except as set forth on Schedule 3.22, to the
Knowledge of UBT, no Employee Plan or Benefit Arrangement has any liability of
any nature, accrued or contingent, including, without limitation, liabilities
for federal, state, local or foreign taxes, interest or penalty other than
liability for claims arising in the course of the administration of each such
plan.  There is no pending or, to the Knowledge of UBT, threatened legal
action, proceeding or investigation against any Employee Plan, other than
routine claims for benefits, which could result in liability to such plans and
there is no basis for any such legal action or proceeding.

                          3.22.7 Each Benefit Arrangement which is a group
health plan (within the meaning of such term under IRC Section 4980B(g)(2))
complies and has complied in all material respects with the requirements of
Section 601 through 608 of ERISA or Section 4980B of the IRC governing
continuation coverage requirements for employee-provided group health plans.

                          3.22.8 Except as disclosed in Schedule 3.22, none of
UBT or any Subsidiary maintains any Employee Plan or Benefit Arrangement
pursuant to which any benefit or other payment will be required to be made by
UBT or any Subsidiary or Affiliate or pursuant to which any other benefit will
accrue or vest in any director, officer or employee of UBT or any Subsidiary or
Affiliate, in either case as a result of the consummation of the transactions
contemplated by this Agreement.

                          3.22.9 No "reportable event," as defined in ERISA,
has occurred with respect to any of the Employee Plans.
                                                
         Section 3.23     Powers of Attorney. No power of attorney or similar
authorization given by UBT or any Subsidiary is presently in effect or
outstanding other than powers of attorney given in the ordinary course of
business with respect to routine matters.

         Section 3.24     [Reserved].

         Section 3.25     Intellectual Property Rights. Schedule 3.25 is a
complete and accurate list of all United States and foreign patents,
trademarks, service marks, copyrights and all pending applications therefor,
whether or not issued (the "Intellectual Property"), that relate to or arise
from

or are used in the operation of the businesses of UBT and its Subsidiaries or
the rights of UBT and its Subsidiaries thereunder.  There are no material
claims or demands of any Person pertaining to the Intellectual Property, and no
proceedings have been instituted or are pending or threatened, which challenge
the rights of UBT and its Subsidiaries in respect thereof, and to the Knowledge
of UBT, none of the Intellectual Property is being infringed upon or
appropriated by others, and none is subject to any outstanding order, decree,
judgment, stipulation, injunction, restriction or agreement affecting the scope
of the free and unrestricted use by UBT or any Subsidiary.  To the Knowledge of
UBT, none of UBT or any Subsidiary is infringing or violating, and has not so
infringed or violated, any Intellectual Property rights of others.

         Section 3.26     Hazardous Materials.

                          3.26.1 Except for ordinary and necessary quantities

otherwise deposited, on or in any real property which is now or has been
previously owned or leased in the past two years by UBT or any Subsidiary,
including (Other Real Estate Owned)(collectively, the "Property"), or to UBT's
Knowledge (based upon a review of UBT's loan origination documentation, as and
if updated upon renewal), on or in any real property in which UBT or any
Subsidiary now holds any security interest, mortgage or other lien or interest,
except for (i) Disclosed Matters; (ii) ordinary and necessary quantities of
cleaning, pest control and office supplies, and other small quantities of
Hazardous Substances used in the ordinary course of UBT's and its Subsidiaries

or bins for regular disposal off-site, or petroleum contained in and de minimus
quantities discharged from motor vehicles in their ordinary operation on the
Property; and (iii) such releases, emissions, disposals or deposits which
constituted a violation of an Environmental Law but did not have a Material
Adverse Effect on the Property involved .  To UBT's Knowledge, (and without
conducting any site investigation or other analysis for the purpose of making

UBT's or any Subsidiary's occupancy of or during any period in which UBT or any
Subsidiary had any rights in the Property that would cause or contribute to:

                                 b.        a release or threatened release of
                                 any Hazardous Substances under circumstances
                                 which would violate any Environmental Laws; or

                                 c.        the discharge of Hazardous

                                 or filling of any waters, that would require a
                                 permit or any other approval under the Federal
                                 Water Pollution Control Act, 33 U.S.C. Section

                                 similar federal or state law or local
                                 ordinance;

Property involved.

                          3.26.4 Except as set forth on Schedule 3.26, to UBT's
Knowledge, (and without conducting any site investigation or other analysis for

<PAGE>   104
Requisite Regulatory Approvals, to consummate the transactions contemplated
hereby. Neither the scope of business of COMERICA or any Subsidiary or the
location of any of their properties requires that COMERICA be licensed to
conduct business in any jurisdiction other than those jurisdictions in which it
is licensed or qualified to do business as a foreign corporation where the
failure to be so licensed or qualified would, individually or in the aggregate,
have a Material Adverse Effect on COMERICA.

         Section 4.2      Licenses and Permits. COMERICA and its Subsidiaries
have all material licenses, certificates, franchises and permits that are
necessary for the conduct of their respective businesses, and such licenses are

conducted, in all material respects, in compliance with all applicable
licenses, certificates, franchises and permits.

This Agreement has been duly executed and delivered by COMERICA and constitutes

in accordance with its terms, except as the enforceability thereof may be
limited by bankruptcy, insolvency, moratorium or other similar laws affecting
the rights of Delaware corporations and bank holding companies generally and by
general equitable principles, and the Subsidiary Merger Agreement, upon due
execution and filing thereof in accordance with the applicable provisions of
the California Corporations Code and California Financial Code, will constitute
a valid and binding obligation of INTERIM, enforceable in accordance with its
terms.

                          4.3.2  The execution and delivery of this Agreement
and the consummation of the transactions contemplated hereby does not and will
not, in the case of COMERICA, and will not, in the case of INTERIM, conflict
with, or result in any violation of or default or loss of a material benefit
under, any provision of the certificate of incorporation or bylaws of COMERICA

COMERICA or any of its Subsidiaries, other than any such conflict, violation,
default or loss which (i) will not have a Material Adverse Effect on COMERICA;
or (ii) will be cured or waived prior to the Effective Time. No material
consent, approval, order or authorization of, or registration, declaration or

Reserve Bank; (b) the OCC; (c) the Federal Deposit Insurance Corporation; (d)
Michigan Banking Commissioner; and (e) any other applicable federal, state or

respective filing dates, each of the past COMERICA Filings (a) was true and
complete in all material respects (or was amended so as to be so promptly
following discovery of any discrepancy); and (b) complied in all material
respects with all of the statutes, rules and regulations enforced or
promulgated by the Governmental Entity with which it was filed (or was amended
so as to be so promptly following discovery of any such noncompliance) and none
contained any untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading.   The COMERICA Financial Statements, together with the financial
statements contained in the COMERICA Filings, have been prepared in accordance
with Generally Accepted Accounting Principles consistently followed throughout
the periods covered by such statements, and present fairly the consolidated
financial position of COMERICA as of the respective dates indicated and the

registration statement and definitive proxy statement and amendments to each of
the foregoing since January 1, 1991 that COMERICA was required to file with the
SEC since such date (the "COMERICA SEC Documents"), all of which have been made

complied in all material respects with the requirements of the Securities Act
and the Exchange Act, as the case may be, and the rules and regulations of the
SEC thereunder applicable to such COMERICA SEC Documents, and none of the
COMERICA SEC Documents contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they
were made, not misleading.  The financial statements of COMERICA included in
the COMERICA SEC Documents comply in all material respects with applicable
accounting requirements and with the published rules and regulations of the SEC
with respect thereto, have been prepared in accordance with Generally Accepted
Accounting Principles applied on a consistent basis during the periods involved
(except as may be indicated in the notes thereto or, in the case of the
unaudited statements, as permitted by Form 10-Q of the SEC) and fairly present
(subject, in the case of the unaudited statements, to recurring adjustments
normal in nature and amount) the consolidated financial position of COMERICA as

circumstances under which they are made, not misleading.

                          4.7.2   None of the information supplied or to be
supplied by COMERICA for inclusion or incorporation by reference in, or
relating to COMERICA and included or incorporated by reference in, (i) the
Registration Statement on Form S-4 to be filed with the SEC by COMERICA in
connection with the issuance of shares of COMERICA Common Stock in the Merger
(including the Proxy Statement and prospectus constituting a part thereof, the
"Registration Statement") will, at the time the Registration Statement becomes
effective under the Securities Act, contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading; (ii) the Proxy Statement and any
amendment or supplement thereto will, at all times from the date of mailing to
shareholders of UBT through the date of the meeting of shareholders of UBT to
be held in connection with the Merger, contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading; and (iii) the statements, correspondence,
applications and forms to be filed with securities or "blue sky" authorities,
self regulatory authorities, the NYSE or any Governmental Entity in connection
with the Merger, the issuance of any shares of COMERICA Common Stock in
connection with the Merger, or any Requisite Regulatory Approvals will, at the
time filed or at the time they become effective, contain any untrue statement
of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.   The Registration
Statement (except for such portions thereof that relate only to UBT and its
Subsidiaries) will comply in all material respects with the provisions of the
Securities Act and the rules and regulations thereunder.

         Section 4.8      Compliance With Applicable Laws. Except as disclosed
in the COMERICA SEC Documents filed prior to the date of this Agreement, the
businesses of COMERICA and its Subsidiaries are not being conducted in
violation of any law, ordinance or regulation, except for violations which
individually or in the aggregate would not, have a Material Adverse Effect on
COMERICA and its Subsidiaries taken as a whole.  No investigation or review by
any Governmental Entity with respect to COMERICA is pending or, to the
knowledge of COMERICA, threatened, nor has any Governmental Entity indicated to
COMERICA an intention to conduct the same, other than those previously
disclosed to UBT, the outcome of which, as far as can be reasonably foreseen,
will not have a Material Adverse Effect on COMERICA or any Subsidiary.

         Section 4.9      Litigation. Except as disclosed in the COMERICA SEC
Documents, there is no suit, action or proceeding pending or, to the Knowledge
of COMERICA, threatened against or affecting COMERICA and its Subsidiaries
which, if adversely determined, would have a Material Adverse Effect on
COMERICA or any Subsidiary of COMERICA taken as a whole; nor is there any
judgment, decree, injunction, rule or order of any Governmental Entity or
arbitrator outstanding against COMERICA or any Subsidiary of COMERICA having,
or which, insofar as reasonably can be foreseen, in the future would have, any
such effect.

         Section 4.10     Agreements with Banking Authorities. Except as set
forth on Schedule 4.10, none of COMERICA or its banking subsidiaries is a party
to any written agreement, memorandum of understanding or order or directive
with any Governmental Entity.

         Section 4.11     Performance of Obligations. COMERICA and its
Subsidiaries have performed in all material respects all of the obligations
required to be performed by them to date and none of COMERICA nor any of its
Subsidiaries is in default under or in breach of any term or provision of any
covenant, contract, lease, indenture or any other covenant to which it is a
party, is subject or is otherwise bound, and no event has occurred that, with
the giving of notice or the passage of time or both, would constitute such
default or breach, where such default or breach would have a Material Adverse
Effect on COMERICA and its Subsidiaries, taken as a whole. To COMERICA's
Knowledge, no party with whom COMERICA or its Subsidiaries has an agreement
that is of material importance to the business of COMERICA and its Subsidiaries
taken as a whole, is in default thereunder.

         Section 4.12     Brokers and Finders. COMERICA is not a party to or
obligated under any agreement with any broker or finder relating to the
transactions contemplated hereby, and neither the execution of this Agreement
or the Subsidiary Merger Agreement nor the consummation of the transaction
provided for herein or therein will result in any liability to any broker or
finder.  COMERICA agrees to indemnify and hold harmless UBT and its affiliates
and to defend with counsel selected by UBT and reasonably satisfactory to
COMERICA from and against any liability, cost or expense, including attorneys'
fees, incurred in connection with a breach of this Section 4.12.

         Section 4.13     Absence of Material Adverse Change. Except as
disclosed in COMERICA SEC Documents, since December 31, 1993, the businesses of
COMERICA and its Subsidiaries have been conducted only in the ordinary course,
in the same manner as theretofore conducted, and no event or circumstance has
occurred or is expected to occur which resulted in or is likely to result in a
Material Adverse Effect on COMERICA.

         Section 4.14     Undisclosed Liabilities. COMERICA and its
Subsidiaries have no liabilities or obligations, either accrued, contingent or
otherwise, that are material to COMERICA and its Subsidiaries taken as a whole
and that have not been: (a) reflected or disclosed in the COMERICA Financial
Statements; (b) incurred subsequent to January 1, 1994 in the ordinary course
of business consistent with past practice; or (c) disclosed in writing to UBT
prior to the date of this Agreement. COMERICA knows of no basis for the
assertion against it or any of its Subsidiaries of any liability, obligation or
claim (including without limitation that of any Governmental Entity) that is
likely to result in or cause a Material Adverse Effect on COMERICA and its
Subsidiaries, taken as a whole, that is not fairly reflected in the COMERICA
Financial Statements or otherwise disclosed in writing to UBT prior to the date
of this Agreement.

         Section 4.15     Disclosure in Schedules.  Anything disclosed by
COMERICA or any of its Subsidiaries in the Schedules to this Agreement shall be
considered to have been disclosed for purposes of all representations,
warranties and covenants of such party under this Agreement.





                                       32
<PAGE>   109
         Section 4.16     No Actual Knowledge of Misrepresentation or Breach of
Warranty.     In connection with any investigation of UBT conducted by
COMERICA, COMERICA has not, to its Knowledge, failed to advise UBT on or before
the date hereof of any Knowledge COMERICA may have that any of the
representations or warranties of UBT contained in this Agreement or in the
exhibits and schedules to this Agreement are not true.

         Section 4.17     Taxes.

                          4.17.1 Filing of Returns.  COMERICA has duly prepared
and filed federal, state, local and foreign Returns (for tax or informational
purposes) which were required to be filed by or in respect of COMERICA and its
Subsidiaries, or any of their properties, income and/or operations on or prior
to the Closing Date.  As of the time of filing, the foregoing Returns correctly
reflect the material facts regarding the income, business, assets, operations,
activities, status, and any other information required to be shown thereon.

                          4.17.2 Payment of Taxes.  With respect to all Taxes
imposed on COMERICA or any Subsidiary or for which COMERICA is or could be
liable, whether to taxing authorities (as, for example, under law) or to other
Persons or entities (as, for example, under tax allocation agreements), with
respect to all taxable periods or portions of periods ending on or before the
Closing Date, all applicable tax laws and agreements have been or will be fully
complied with, and all such amounts required to be paid by or on behalf of
COMERICA or any Subsidiary to taxing authorities or others on or before the
date hereof have been paid.

                          4.17.3 Audit History.   Except as previously
disclosed to UBT, there has not, within the last year, been any review or audit
by any taxing authority of any Tax liability of COMERICA or any Subsidiary.
Except as previously disclosed to UBT, COMERICA and its Subsidiaries have not
received any notice of any pending or threatened audit by the Internal Revenue
Service or any state, local or foreign agency related to COMERICA's and its
Subsidiaries' Tax or information returns or Tax liability for any period and no
claim for assessment or collection of Taxes has been asserted against COMERICA
or its Subsidiaries.  COMERICA and its Subsidiaries currently have no unpaid
deficiency assessed by the Internal Revenue Service or any state, local or
foreign taxing authority with respect to any of COMERICA's and its
Subsidiaries' Tax returns filed for fiscal years ended on or after December 31,
1993 through Closing Date, nor, to the Knowledge of COMERICA, is there reason
to believe that any deficiency will be assessed.





                                       33
<PAGE>   110
         Section 4.18     No Knowledge Regarding Approvals.    COMERICA has no
reason to believe that the Requisite Regulatory Approvals will impose any
condition which is materially burdensome upon UBT, COMERICA, INTERIM, their
respective Affiliates or the Surviving Corporation or will require the
divestiture by COMERICA of any material Subsidiary or of a material portion of
the business of COMERICA.

         Section 4.19     Effective Date of Representations, Warranties,
Covenants and Agreements.  Each representation, warranty, covenant and
agreement of COMERICA set forth in this Agreement shall be deemed to be made on
and as of the date hereof and as of the Effective Time.


ARTICLE 5  ADDITIONAL AGREEMENTS

         Section 5.1      Access to Information, Due Diligence, etc.

                          5.1.1  Upon reasonable notice, UBT and its
subsidiaries shall allow COMERICA and INTERIM and their accountants, counsel
and other representatives reasonable access during business hours to its
officers, employees, properties, books, contracts, commitments and records and
from the date hereof through the Effective Time, shall furnish to COMERICA as
soon as practicable, (i) a copy of each UBT Filing filed since the date of this
Agreement after such document has been filed with the appropriate Governmental
Entity; (ii) unless otherwise prohibited by law, a copy of each report,
schedule and other documents filed or received by it during such period with
any Regulatory Authority or the Internal Revenue Service (as to documents other
than related to employees or customers and other than those distributed to
banks generally); (iii) as promptly as practicable following the end of each
calendar month after the date hereof, a consolidated balance sheet of UBT as of
the end of such month; and (iv) all other information concerning its business,
properties, assets, financial condition, results of operations, liabilities,
personnel and otherwise as COMERICA or INTERIM may reasonably request.

                          5.1.2  Upon reasonable notice, COMERICA shall allow
UBT and its accountants, counsel and other representatives such access to its
officers, employees, properties, books, contracts, commitments and records as
COMERICA provides to financial analysts in the normal course of business and,
from the date hereof through the Effective Time at UBT's request, shall furnish
to UBT as soon as practicable, a copy of each COMERICA SEC Document filed since
the date of this Agreement and any other information relating to its existing
business, properties, financial condition, results of operations and personnel
as UBT may reasonably request.

                          5.1.3  UBT, INTERIM and COMERICA each agrees to keep
confidential and not divulge to any other party or Person (other than to the
employees, attorneys, accountants and consultants of each who have a need to
receive such information and other than as may be required by law or the rules
of the NYSE) any information received from the other, unless and until the
earlier of (i) the second anniversary of the date on which this Agreement
terminates; and (ii) the date on





                                       34
<PAGE>   111
which such documents and other information otherwise becomes publicly
available.  In the event of termination of this Agreement for any reason, the
parties shall promptly return or at the election of the other party destroy all
documents obtained from the other and any copies or notes of such documents
(except as otherwise required by law) and, upon the request of the other party,
confirm such destruction to the other in writing.

         Section 5.2      Shareholder Approval.

                          5.2.1  UBT shall promptly call a meeting of its
shareholders to be held at the earliest practicable date after the date on
which the initial Registration Statement is filed with the SEC for the purpose
of ratifying and confirming this Agreement and authorizing the Subsidiary
Merger Agreement and the Merger.  The UBT Board of Directors will recommend to
the UBT shareholders ratification and confirmation of this Agreement, the
Subsidiary Merger Agreement and the Merger; provided, however, that the UBT
Board of Directors may withdraw such recommendation if such Board of Directors
believes in good faith that a Superior Proposal (defined below) has been made
and shall have determined in good faith, after consultation with its outside
legal counsel, that the withdrawal of such recommendation is necessary for such
Board of Directors to comply with its fiduciary duties under applicable law.

                          5.2.2  Prior to the Effective Time of the Merger,
COMERICA, as the sole shareholder of INTERIM, shall take all action proper or
advisable for the consummation of the Merger by INTERIM.

         Section 5.3      Taking of Necessary Action.

                          5.3.1  Subject to the terms and conditions of this
Agreement, each of the parties hereto agrees, subject to applicable laws and
the fiduciary duties of UBT's, COMERICA's or INTERIM's Board of Directors as
advised in writing by counsel, to use all reasonable efforts promptly to take
or cause to be taken all action and promptly to do or cause to be done all
things necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by this Agreement
and the Subsidiary Merger Agreement, including, without limitation, the
delivery of any certificate or other document reasonably requested by counsel
to a party to this Agreement.  Without limiting the foregoing, COMERICA, UBT
and INTERIM will use their reasonable efforts to obtain all consents of third
parties and Government Entities necessary or, in the reasonable opinion of
COMERICA and INTERIM or UBT, advisable for the consummation of the transactions
contemplated by this Agreement.  Without limiting the foregoing, COMERICA shall
cause INTERIM to take all actions necessary to execute and file the Subsidiary
Merger Agreement and to effect all transactions contemplated of INTERIM by this
Agreement.  In case at any time after the Effective Time any further action is
necessary or desirable to carry out the purposes of this Agreement or the
Subsidiary Merger Agreement, or to vest the Surviving Corporation with full
title to all properties, assets, rights, approvals, immunities and franchises
of UBT and its Subsidiaries, the proper officers or directors of COMERICA,
INTERIM or UBT, as the case may be, shall take all such necessary action.





                                       35
<PAGE>   112
                          5.3.2  UBT shall use its best efforts to cause each
director, executive officer and other Person who is an "affiliate" (for
purposes of Rule 145 under the Securities Act and for purposes of qualifying
for "pooling-of-interests" treatment for accounting purposes) of UBT to deliver
to COMERICA, within 20 Business Days after the date of this Agreement and in
any event prior to the date the Registration Statement on Form S-4 is initially
filed, a written agreement in the form attached hereto as Exhibit 7.2.15.

         Section 5.4      Registration Statement and Applications.

                          5.4.1  COMERICA and UBT will cooperate and jointly
prepare and file as promptly as practicable the Registration Statement (in
which the Proxy Statement will be included as a prospectus), the statements,
applications, correspondence or forms to be filed with appropriate State
securities law regulatory authorities, and the statements, correspondence,
applications or forms to be filed to obtain the Requisite Regulatory Approvals
to consummate the transactions contemplated by this Agreement.  Each of
COMERICA and UBT shall use all reasonable efforts to have the Registration
Statement declared  effective under the Securities Act as promptly as
practicable after such filing, and thereafter mail the Proxy Statement to UBT's
shareholders.  COMERICA shall prepare and file the listing application to be
filed with the New York Stock Exchange with respect to the COMERICA Common
Stock to be issued in the Merger.  Each party will furnish all financial or
other information, including independent public accountant comfort letters
relating thereto, certificates, consents and opinions of counsel concerning it
and its Subsidiaries reasonably deemed necessary by the other party for the
filing or preparation for filing of the Registration Statement and related
matters.

                          5.4.2  Each party shall provide to the other at the
request of the other party: (i) immediately prior to the filing thereof, copies
of all material statements, applications, correspondence or forms to be filed
with State securities law regulatory authorities, the SEC and other appropriate
regulatory authorities to obtain the Requisite Regulatory Approvals to
consummate the transactions contemplated by this Agreement; provided, however,
that no approval need be obtained from any party to which such materials are
provided; and (ii) promptly after delivery to, or receipt from, such regulatory
authorities all written communications, letters, reports or other documents
relating to the transactions contemplated by this Agreement.

                          5.4.3  COMERICA,  INTERIM and UBT shall receive
opinions of their respective counsel, addressed to the parties and dated the
date the Registration Statement becomes effective and the date of the
shareholders meeting in substantially the forms previously agreed upon.

         Section 5.5      Expenses.

                          5.5.1  Whether or not the Merger is consummated, all
costs and expenses incurred in connection with this Agreement and the
transactions contemplated hereby shall be paid by the party incurring the same;
provided, however, that COMERICA will file on a timely basis at its own expense
the reports required by Rule 144(c) of the Securities Act.





                                       36
<PAGE>   113
                          5.5.2  UBT's expenses incurred in connection with
this Agreement and the transactions contemplated by this Agreement, including
attorneys', accountants', investment bankers' and any other fees, collectively
shall not exceed the sum of $1,500,000 without the prior written approval of
COMERICA, which shall not be unreasonably withheld.  UBT shall use its best
efforts to ensure that its attorneys, accountants, investment bankers and other
consultants engaged in connection with the transaction contemplated by this
Agreement submit full and final bills on the Closing Date.

         Section 5.6      Notification of Certain Events.

                          5.6.1  UBT shall provide to COMERICA and INTERIM, as
soon as practicable, written notice (sent via facsimile and overnight mail or
courier) of the occurrence or failure to occur of any of the events,
circumstances or conditions that are the subject of Sections 6.1 and 6.2, which
notice shall provide reasonable detail as to the subject matter thereof.

                          5.6.2  COMERICA shall provide to UBT as soon as
practicable, written notice (sent via facsimile and overnight mail or courier)
of the occurrence or failure to occur of any of the events, circumstances or
conditions that are the subject of Section 6.3, which notice shall provide
reasonable detail as to the subject matter thereof.

                          5.6.3  The parties shall promptly advise each other
in writing of any change or event which could reasonably be expected to have a
Material Adverse Effect on any such party.

                          5.6.4  UBT shall immediately notify COMERICA in
writing in the event that UBT becomes aware that the Registration Statement or
Proxy Statement at any time contains any untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading or that the Registration Statement or the Proxy
Statement otherwise is required to be amended as supplemented, which notice
shall specify, in reasonable detail, the circumstances thereof.

         Section 5.7      Environmental Assessment.

                          5.7.1  COMERICA and INTERIM shall have the right to
conduct before the Closing Date, but to be commenced no later than 60 days
after the date of this Agreement, at their sole expense, environmental site
investigations and assessments ("Site Assessments") covering any real property
owned or leased by UBT (including Other Real Estate Owned) or held in trust or
otherwise managed by UBT, for the purpose of determining whether there exists
on such real property any environmental condition which could result in any
liability, cost or expense to COMERICA, INTERIM, the Surviving Corporation or
any other owner, user or occupant of such property relating to Hazardous
Substances or other adverse environmental conditions.  Such Site Assessment may
include both above and below the ground testing for environmental damage or the
presence of Hazardous Substances on such property as may be reasonably
necessary to conduct the





                                       37
<PAGE>   114
Site Assessment in the opinion of the persons conducting such Site Assessment
and UBT shall allow such persons access to such property during normal business
hours and upon reasonable prior notice in order to permit them to conduct the
Site Assessment and shall otherwise cooperate with such persons in connection
therewith.  In exercising its rights hereunder, COMERICA shall coordinate with
UBT to avoid unduly interfering with the conduct of business by UBT and its
Subsidiaries.  For invasive testing (exclusive of asbestos sampling)(e.g., soil
and soil boring testing), COMERICA will first present to UBT the plan of
testing that is contemplated by COMERICA and COMERICA may not conduct such
testing without UBT's prior written consent, which shall not be unreasonably
withheld or delayed.  In connection with such inspection and testing, COMERICA
shall obtain at its sole cost and expense all permits and licenses required in
connection with the performance of such work.  COMERICA shall repair any
damages caused by its tests or inspections.  COMERICA hereby indemnifies UBT
for all injuries and damages to persons or property caused by such surveys and
testing for the cost of removing all mechanics' or materialmen's liens on the
inspected property resulting from such surveys and testing ordered by COMERICA.
As used herein, "Disclosed Matters" shall mean all information contained in the
Site Assessments obtained by COMERICA.

                          5.7.2  If any such Site Assessment discloses any
environmental condition which would be reasonably likely to have a Material
Adverse Effect on such real property, COMERICA and INTERIM shall have the right
and option to terminate this Agreement prior to the Closing Date and to declare
it null and void pursuant to Section 8.1.9 of this Agreement by delivering
written notice of termination to UBT within thirty (30) days after the receipt
of each such Site Assessment and including with such notice a copy of such Site
Assessment.  For purposes of this Section 5.7.2, Material Adverse Effect shall
mean a diminution in value (from the appraised value of the property in
question),  of more than ten percent and at least $150,000.

                          5.7.3  COMERICA and INTERIM shall not provide any
such Site Assessment, or any non-public information contained therein, to any
third party, including any Governmental Entity, unless otherwise required to do
so by law or regulation.

         Section 5.8      Schedules, Closing Schedules.     All schedules
referred to in this Agreement have be previously and separately delivered by
the parties.  On the Closing Date, UBT shall prepare updates of the schedules
provided for in Articles 3 and 7 of this Agreement and shall deliver to
COMERICA revised schedules containing the updated information (the "Closing
Schedules")(or a certificate signed by UBT's Chief Executive Officer stating
that there have been no changes on the applicable schedules).  The Closing
Schedules shall be dated as of the day prior to the Closing Date and shall
contain information as of the day prior to the Closing Date or as of such
earlier date as is practicable in the circumstance.

         Section 5.9      Indemnification and Insurance.

                          5.9.1  For a period of six years after the Effective
Time, COMERICA shall use its commercially reasonable efforts to cause to be
maintained in effect policies of directors' and officers' liability insurance
(with such coverage, terms and conditions as are no less advantageous than





                                       38
<PAGE>   115
the insurance presently maintained by COMERICA with respect to its officers and
directors) with respect to all matters arising from facts or events which
occurred before the Effective Time for which UBT would have had an obligation
to indemnify their directors and officers; provided, however, that in no event
shall COMERICA be obligated to expend, in order to maintain or provide
insurance coverage pursuant to this Section 5.9.1 any amount per annum in
excess of 300% of the amount of the 1994 annual premiums paid by UBT for such
insurance (the "Maximum Amount").  If the amount of the annual premiums
necessary to maintain or procure such insurance coverage exceeds the Maximum
Amount, COMERICA shall use all reasonable efforts to maintain the most
advantageous policies of directors' and officers' insurance obtainable for an
annual premium equal to the Maximum Amount.

                          5.9.2  COMERICA agrees that all rights to
indemnification and all limitations of liability existing in favor of the
directors and officers of UBT as provided in UBT's Articles of Incorporation or
Bylaws or any Indemnification Agreement with respect to matters occurring prior
to the Effective Time shall survive the Merger and shall continue in full force
and effect, without any amendment thereto, for a period of six years from the
Effective Time; provided, however, that  all rights to indemnification in
respect of any claim (a "Claim") asserted or made within such period shall
continue until the final disposition of such Claim.  Nothing contained in this
Section 5.9.2 shall be deemed to preclude any rights to indemnification or
limitations on liability provided in UBT's Articles of Incorporation or Bylaws
or the similar governing documents of any of UBT's Subsidiaries with respect to
matters occurring subsequent to the Effective Time to the extent that the
provisions establishing such rights or limitations are not otherwise amended to
the contrary.

                          5.9.3  If COMERICA 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 consolidation or merger or (ii) shall transfer all or substantially all of
its properties and assets to any individual, corporation or other entity, then
and in each such case, COMERICA shall take no action to impair the rights
provided in this Section 5.9.

                          5.9.4  The provisions of this Section are intended to
be for the benefit of, and shall be enforceable by, each director or officer of
UBT and his or her heirs and representatives.

         Section 5.10     Additional Accruals.

                          5.10.1 At COMERICA's or INTERIM's request, UBT shall,
consistent with Generally Accepted Accounting Principles, establish such
additional accruals and reserves immediately prior to the Effective Time as may
be necessary to conform UBT's accounting and credit loss reserve practices and
methods to those of COMERICA and INTERIM or its Subsidiaries; provided,
however, that no accrual or reserve made by UBT pursuant to this Section
5.10.1, or any litigation or regulatory proceeding arising out of any such
accrual or reserve, or any other effect on UBT resulting from UBT's compliance
with this Section 5.10.1, shall constitute or be deemed to be a breach,
violation of or failure to satisfy any representation, warranty, covenant,
condition or other provision of this Agreement or otherwise be considered in
determining whether any such breach,





                                       39
<PAGE>   116
violation or failure to satisfy shall have occurred; and provided further,

                          6.1.6  Duly observe and conform to all legal
requirements applicable to its business, except for any failure to so observe

                          6.2.2  take any action that would result in any of
the representations and warranties set forth in the Agreement becoming untrue

concerning any Acquisition Proposal.  UBT shall notify COMERICA immediately if
an inquiry regarding an Acquisition Proposal is received by UBT, including the
terms thereof.  For purposes of this Section 6.2.5, "Acquisition Proposal"

information to, or entering into discussions or negotiations with, any person
or entity in connection with an unsolicited bona fide written Acquisition
Proposal by such person or entity or recommending an unsolicited bona fide
written Acquisition Proposal to the shareholders of UBT, if and only to the
extent that (1) the Board of Directors of UBT believes in good faith (after
consultation with and the concurrence of its financial advisor) that such
Acquisition Proposal would, if consummated, result in a transaction materially
more favorable to UBT's shareholders from a financial point of view than the
transaction contemplated by this Agreement (any such more favorable Acquisition
Proposal being referred to in this Agreement as a "Superior Proposal") and the
UBT Board of Directors determined in good faith after consultation with its
outside legal counsel that such action is necessary for UBT to comply with its
fiduciary duties to shareholders under applicable law and (2) prior to
furnishing such non-public information to, or entering into discussions or
negotiations with, such person or entity, the UBT Board of Directors received
from such person or entity an executed confidentiality agreement, with terms no
more favorable to such party than those contained in the Confidentiality
Agreement between UBT and COMERICA, or (B) complying with Rule 14e-2

other extensions of credit in the ordinary course of business and consistent
with prior practice; (C) commitments to act as trustee or agent in the ordinary

however, that the date must follow, among other things, the approval of the
merger by the sole shareholder of UBT and Interim and by the Superintendent of
the California State Banking Department.  The close of business on the day on
which the merger shall become effective is herein referred to as the "Effective
Date."

SECTION 10.      At the Effective Date of the merger, the corporate existence
of the Merging Parties shall be consolidated into and continued in the
Surviving Institution, which shall be deemed to be the same corporation as 
each of the Merging Parties, possessing all the rights, privileges, powers and
franchises, and subject to all the restrictions, disabilities and duties of the
Merging Parties, except as such rights, privileges, powers and franchises may 
be limited by law.  Upon the merger becoming effective, all the provisions of 
law regarding the effects of merger shall be effective with respect to the 
merger and the Surviving Institution, including, without limitation, the 
following:




                                       2
<PAGE>   134
         A.      All of the rights, interests, privileges, powers, and
franchises of the Merging Parties, both of a public and private nature, shall
vest in the Surviving Institution without further act or deed as effectively as
the same were vested in the Merging Parties prior to the merger.

         B.      All property, real, personal and mixed, including, without
limitation, all debts due, chooses in action of every description, licenses,
registrations, and other assets of every kind and description of the Merging
Parties shall, without further act or deed, be transferred to, vested in and
devolve upon the Surviving Institution, and shall be as effectively the
property of the Surviving Institution as they were of the Merging Parties prior
to the merger without any deed or other transfer and without any order or other
action on the part of any court or otherwise.

         C.      Title to any real estate, whether vested by deed or otherwise,
in the Merging Parties shall not revert or be in any way impaired by reason of
the merger or otherwise.

         D.      The Surviving Institution shall thenceforth be subject to all
of the restrictions, disabilities, duties, liabilities and obligations of the
Merging Parties and the same may thereafter be enforced against it to the same
extent as if the same had been incurred or contracted by the Surviving
Institution.

         E.      The Surviving Institution, by virtue of the merger, and
without any order or other action on the part of any court or otherwise, shall
hold and enjoy the same and all rights of property, franchises and interests,
including appointments, designations, and nominations and all other rights and
interest as trustee, executor, administrator, registrar of stocks and bonds,
guardian of estates, assignee, receiver, guardian of mentally incompetent
persons and in every other fiduciary capacity, in the same manner and to the
same extent as such rights, franchises and interests were held or enjoyed by
the Merging Parties, or either of them, at the time of the merger.

         F.      Any action or proceeding pending by or against the Merging
Parties may be prosecuted to judgment to the same extent as if the merger had
not taken place, which judgment shall bind the Surviving Institution, or,
alternatively, the Surviving Institution may be proceeded against or
substituted in place of the Merging Parties in any such action or proceeding.

The officers and directors of the Merging Parties shall, from time to time, as
and when requested by the Surviving Institution or its successors or assigns,
execute and deliver or cause to be executed and delivered, such deeds,
instruments, assignments, or assurances as the Surviving Institution may deem
necessary, desirable, or convenient in order to vest in and confirm to the
Surviving Institution title to or possession of any property or rights of the
Merging Parties acquired or to be acquired by reason of or as a result of the
merger, or otherwise to carry out the purposes of this Merger Agreement.  Any
person who, immediately before the merger became effective, was an officer or
director of the Merging Parties is hereby fully authorized, in the name of such
institution, to execute any and all such deeds, instruments, assignments, or
assurances, or to take any and all such action as may be requested by the
Surviving Institution.

SECTION 11.      The manner of converting the shares of the Merging Parties
into shares of the Surviving Institution shall be as follows:





                                       3
<PAGE>   135
Upon the Effective Date of merger, each share of common stock of UBT then
issued and outstanding shall be, and hereby is, by virtue of the merger and
without any action on the part of the holder thereof, converted into the right
to receive _________________.  Each share of common stock of Interim then
issued and outstanding shall be, and hereby is, by virtue of the merger and
without any action on the part of the holder thereof, converted into and
constitute the shares of the common stock, no par value, of the Surviving
Institution, and all the shares of the Surviving Institution shall be owned by
Comerica Incorporated, a Delaware corporation.

SECTION 12.      This Agreement of Merger may be terminated by the unilateral
action of the board of directors of either of the Merging Parties prior to the
approval of the sole shareholder of either of the Merging Parties or by the
mutual consent of the boards of both of the Merging Parties after the sole
shareholder of either of the Merging Parties has taken affirmative action.

SECTION 13.      This Agreement shall be ratified and confirmed by written
consent resolution of the sole shareholder of each of the Merging Parties in
lieu of a shareholders' meeting.

SECTION 14.      This Agreement may be executed in one or more counterparts,
all of which shall be taken together to constitute one and the same instrument
and shall be binding upon each party who may sign a counterpart of this
instrument.

IN WITNESS WHEREOF, UBT and Interim, pursuant to the approval and authority
duly given by resolution of their respective Boards of Directors, have caused
this Merger Agreement to be signed by their respective Presidents and
Secretaries on this day and year first above written.

                                   CHAPTER 13

                               DISSENTER'S RIGHTS


Section  1300. REORGANIZATION OR SHORT-FORM MERGER; DISSENTING SHARES;
               CORPORATE PURCHASE AT FAIR MARKET VALUE; DEFINITIONS

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

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

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

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

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

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

<PAGE>   137
  (c)  As used in this chapter, "dissenting shareholder" means the recordholder
of dissenting shares and includes a transferee of record.


Section  1301. NOTICE TO HOLDERS OF DISSENTING SHARES IN REORGANIZATIONS;
               DEMAND FOR PURCHASE; TIME; CONTENTS

  (a)  If, in the case of a reorganization, any shareholders of a corporation
have a right under Section 1300, subject to compliance with paragraphs (3) and
(4) of subdivision (b) thereof, to require the corporation to purchase their
shares for cash, such corporation shall mail to each such shareholder a notice
of the approval of the reorganization by its outstanding shares (Section 152)
within 10 days after the date of such approval, accompanied by a copy of
Sections 1300, 1302, 1303, 1304 and this section, a statement of the price
determined by the corporation to represent the fair market value of the
dissenting shares, and a brief description of the procedure to be followed if
the shareholder desires to exercise the shareholder's right under such
sections.  The statement of price constitutes an offer by the corporation to
purchase at the price stated any dissenting shares as defined in subdivision
(b) of Section 1300, unless they lose their status as dissenting shares under
Section 1309.

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

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


Section  1302. SUBMISSION OF SHARE CERTIFICATES FOR ENDORSEMENT; UNCERTIFICATED
               SECURITIES

Within 30 days after the date on which notice of the approval by the
outstanding shares or the notice pursuant to subdivision (i) of Section 1110
was mailed to the shareholder, the shareholder shall submit to the corporation
at its principal office or at the office of any transfer agent thereof, (a) if
the shares are certificated securities, the shareholder's certificates
representing any shares which the shareholder demands that the corporation
purchase, to be stamped or endorsed with a statement that the shares are
dissenting shares or to be exchanged for certificates of





                                       2
<PAGE>   138
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. PAYMENT OF AGREED PRICE WITH INTEREST; AGREEMENT FIXING FAIR
               MARKET VALUE; FILING; TIME OF 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. ACTION TO DETERMINE WHETHER SHARES ARE DISSENTING SHARES OR FAIR
               MARKET VALUE; LIMITATION; JOINDER; CONSOLIDATION; DETERMINATION
               OF ISSUES;  APPOINTMENT OF APPRAISERS

  (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 shareholders may join as plaintiffs or be joined
as defendants in any such action and two or more such actions may be
consolidated.

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

<PAGE>   139
Section  1305. REPORT OF APPRAISERS; CONFIRMATION; DETERMINATION BY COURT;
JUDGMENT; PAYMENT; APPEAL; 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. PREVENTION OF IMMEDIATE PAYMENT; STATUS AS CREDITORS; INTEREST

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.





                                       4
<PAGE>   140
Section  1307. DIVIDENDS ON DISSENTING SHARES

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


Section  1308. RIGHTS OF DISSENTING SHAREHOLDERS PENDING VALUATION; WITHDRAWAL
               OF DEMAND FOR PAYMENT

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 SHARE AND 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>   141
Section  1310. SUSPENSION OF RIGHT TO COMPENSATION OR VALUATION PROCEEDINGS;
               LITIGATION OF SHAREHOLDERS' APPROVAL

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


Section  1311.   EXEMPT SHARES

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


Section  1312. RIGHT OF DISSENTING SHAREHOLDER TO ATTACK, SET ASIDE OR RESCIND
               MERGER OR REORGANIZATION; RESTRAINING ORDER OR INJUNCTION;
               CONDITIONS

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

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

  (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





                                       6
<PAGE>   142
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.

December 19, 1994                             



Board of Directors
University Bank & Trust Company
250 Lytton Avenue
Palo Alto, CA  94302

Gentlemen and Mesdames:

You have requested our opinion as to the fairness to the holders of the
outstanding shares of Common Stock, par value $2.50 per share (the "Shares"), of
University Bank & Trust Company (the "Company") of the exchange ratio, subject
to adjustment pursuant to the Agreement, as defined below, of 1.7456 shares of
Common Stock, par value $5.00 per Share, of Comerica Incorporated ("Comerica"),
to be received for each Share (the "Exchange Ratio") pursuant to the Agreement
and Plan of Reorganization and Merger dated as of October 4, 1994 among the
Company, Comerica Interim Incorporated, a wholly-owned subsidiary of Comerica,
and Comerica (the "Agreement").

Goldman, Sachs & Co., as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
biddings, secondary distributions of listed and unlisted securities, private
placements and valuations for estate, corporate and other purposes.  We are
familiar with the Company having acted as its financial advisor in connection
with, and having participated in certain of the negotiations leading to, the
Agreement. We have also provided certain investment banking services to Comerica
from time to time and may provide investment banking services to Comerica in
the future.

In connection with this opinion, we have reviewed, among other things, the
Agreement; the Registration Statement on Form S-4, including the Proxy
Statement-Prospectus relating to the Special Meeting of Stockholders of
the Company to be held in connection with the Agreement; Annual Reports to
Stockholders and Annual Reports on Form 10-K of the Company for the two years
ended December 31, 1993; Annual Reports to Stockholders and Annual Reports on
Form F-2 of the Company for the three years ended December 31, 1991; Annual
Reports to Stockholders and Annual Reports on Form 10-K of Comerica for the
five years ended December 31, 1993; certain interim reports to stockholders and
Quarterly Reports on Form 10-Q of the Company and of Comerica; certain other
communications from the Company to its stockholders; and certain internal
financial analyses and forecasts for the Company prepared by its management. We
also have held discussions with members of the senior managements of the
Company and Comerica regarding the past and current business operations,
financial condition and future prospects of their respective companies. In
addition, we have reviewed the reported price and trading activity for the
Shares, compared certain financial and stock market information for the Company
with similar information for certain other companies the securities of which
are publicly
<PAGE>   144
University Bank & Trust Company
December 19, 1994

traded, reviewed the financial terms of certain recent business combinations in
the banking industry specifically and in other industries generally and
performed such other studies and analyses as we considered appropriate.

We have relied without independent verification upon the accuracy and
completeness of all of the financial and other information reviewed by us for
purposes of this opinion.  In that regard, we have assumed, with your consent,
that the financial forecasts, including, without limitation, projections
regarding underperforming and nonperforming assets and net chargeoffs, have
been reasonably prepared on a basis reflecting the best currently available
judgments and estimates of the Company and that such forecasts will be realized
in the amounts and at the times contemplated thereby.  We are not experts in
the evaluation of loan and lease portfolios for the purposes of assessing the
adequacy of the allowances for losses with respect thereto and have assumed,
with your consent, that such allowances for each of the Company and Comerica
are in the aggregate adequate to cover all such losses.  In addition, we have
not reviewed individual credit files nor have we made an independent evaluation
or appraisal of the assets and liabilities of the Company or Comerica or any of
their subsidiaries and have not been furnished with any such evaluation or
appraisal.  We also have assumed that Comerica will receive all necessary
regulatory approvals without undue delay.

Based upon and subject to the foregoing and based upon such other matters as we
consider relevant, it is our opinion that as of the date hereof the Exchange
Ratio pursuant to the Agreement is fair to the holders of Shares.

Very truly yours,

/s/ Goldman, Sachs & Co.

and into Issuer, with Issuer as the surviving corporation; and

         WHEREAS, as a condition and inducement to Grantee's execution of the

agreed, to grant Grantee the Option (as defined below);

         NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein and in
the Merger Agreement, and intending to be legally bound hereby, Issuer and
Grantee agree as follows:

of a Purchase Event or a Preliminary Purchase Event (other than a termination

months after the termination of the Merger Agreement by Grantee pursuant to
Section 8.1.6 thereof or by Grantee and Issuer pursuant to Section 8.1.1
thereof if Grantee shall at that time have been entitled to terminate the
Merger Agreement pursuant to Section 8.1.6 thereof (provided, however, that if
within 12 months after such termination of the Merger Agreement a Purchase
Event or a Preliminary Purchase Event shall occur, then notwithstanding

                 of the consolidated assets of Issuer and its Subsidiaries or
                 (C) the issuance, sale or other disposition of (including by
                 way of merger, consolidation, share exchange or any similar
                 transaction) securities representing 10% or more of the voting
                 power of Issuer or any of its Subsidiaries; or

                          (ii) any person (other than Grantee or any Subsidiary
                 of Grantee) shall have acquired beneficial ownership (as such
                 term is defined in Rule 13d-3 promulgated under the Securities
                 Exchange Act of 1934, as amended (the "Exchange Act")) of or

                 registration statement under the Securities Act of 1933, as
                 amended (the "Securities Act"), with respect to, a tender
                 offer or exchange offer to purchase any shares of Issuer
                 Common Stock such that, upon consummation of such offer, such
                 person would own or control 15% or more of the then

                                      2
<PAGE>   147
                 outstanding shares of Issuer Common Stock (such an offer being
                 referred to herein as a "Tender Offer" or an "Exchange Offer
                 respectively); or

                          (ii) the holders of Issuer Common Stock shall not
                 have approved the Merger Agreement at the meeting of such
                 stockholders held for the purpose of voting on the Merger
                 Agreement, such meeting shall not have been held or shall have
                 been cancelled prior to termination of the Merger Agreement,
                 or Issuer's Board of Directors shall have withdrawn or
                 modified in a manner adverse to Grantee the recommendation of
                 Issuer's Board of Directors with respect to the Merger
                 Agreement, in each case after it shall have been publicly
                 announced that any person (other than Grantee or any
                 Subsidiary of Grantee) shall have (A) made or disclosed an
                 intention to make a proposal to engage in an Acquisition
                 Transaction or (B) commenced a Tender Offer or filed a
                 registration statement under the Securities Act with respect
                 to an Exchange Offer.

         As used in this Agreement, "person" shall have the meaning specified
in Sections 3(a)(9) and 13(d)(3) of the Exchange Act.

         (d) In the event Grantee wishes to exercise the Option, it shall send
to Issuer a written notice (the date of which is referred to as the "Notice
Date") specifying (i) the total number of Option Shares it intends to purchase
pursuant to such exercise and (ii) a place and date not earlier than three
business days nor later than 15 business days from the Notice Date for the
closing (the "Closing") of such purchase (the "Closing Date"). If prior
notification to or approval of the Board of Governors of the Federal Reserve
System (the "Federal Reserve Board") or any other regulatory authority is
required in connection with such purchase, Issuer shall cooperate with Grantee
in the filing of the required notice or application for approval and the
obtaining of any such approval.

         4. Payment and Delivery of Certificates. (a) On each Closing Date,
Grantee shall (i) pay to Issuer, in immediately available funds by wire
transfer to a bank account designated by Issuer, an amount equal to the
Purchase Price multiplied by the number of Option Shares to be purchased on
such Closing Date and (ii) present and surrender this Agreement to the Issuer
at the address of the Issuer specified in Section 12(f) hereof.

         (b) At each Closing, simultaneously with the delivery of immediately
available funds and surrender of this Agreement as provided in Section 4(a),
(i) Issuer shall deliver to Grantee (A) a certificate or certificates
representing the Option Shares to be purchased at such Closing, which Option
Shares shall be free and clear of all liens, claims, charges and encumbrances
of any kind whatsoever, and (B) if the Option is exercised in part only, an
executed new agreement with the same terms as this Agreement evidencing the
right to purchase the balance of the shares of Issuer Common Stock purchasable
hereunder, and (ii) Grantee shall deliver to Issuer a letter agreeing that
Grantee shall not offer to sell or otherwise dispose of such Option Shares in
violation of the provisions of this Agreement.

         (c) Certificates for the Option Shares delivered at each Closing shall
be endorsed with a restrictive legend which shall read substantially as
follows:

                 THE TRANSFER OF THE STOCK REPRESENTED BY THIS CERTIFICATE IS
         SUBJECT TO RESTRICTIONS ARISING UNDER THE SECURITIES ACT OF 1933, AS
         AMENDED, AND PURSUANT TO THE TERMS OF A STOCK OPTION AGREEMENT DATED
         AS OF OCTOBER 4, 1994, A COPY OF SUCH AGREEMENT WILL BE PROVIDED TO
         THE HOLDER HEREOF WITHOUT CHARGE UPON RECEIPT BY THE ISSUER OF A
         WRITTEN REQUEST THEREFOR.

         It is understood and agreed that the above legend shall be removed by
delivery of substitute certificate(s) without such legend if Grantee shall have
delivered to Issuer a copy of a letter from the staff of the SEC, or an opinion
of counsel in form and substance reasonably satisfactory to Issuer and its
counsel, to the effect that such legend is not required for purposes of the
Securities Act.

         5. Representations and Warranties of Issuer.  Issuer hereby represents
and warrants to Grantee as follows:

         (a) Due Authorization. Issuer has all requisite corporate power and
authority to enter into this Agreement and, subject to any approvals referred
to herein, to consummate the transactions contemplated hereby. The execution
and delivery of this Agreement and the consummation of the transactions
contemplated hereby have been duly authorized by all necessary corporate action
on the part of Issuer. This Agreement has been duly executed and delivered by
Issuer.

         (b) Authorized Stock. Issuer has taken all necessary corporate and
other action to authorize and reserve and to permit it to issue, and, at all
times from the date hereof until the obligation to deliver Issuer Common Stock
upon the exercise of the Option terminates, will have reserved for issuance,
upon exercise of the Option, shares of Issuer Common Stock necessary for
Grantee to exercise the Option, and Issuer will take all necessary corporate
action to authorize and reserve for issuance all additional shares of Issuer
Common Stock or other securities which may be issued pursuant to Section 7 upon
exercise of the Option. The shares of Issuer Common Stock to be issued upon due
exercise of the Option, including all additional shares of Issuer Common Stock
or other securities which may be issuable pursuant to Section 7, upon issuance
pursuant hereto, shall be duly and validly issued, fully paid and nonassessable
(except for assessments made pursuant to Section 662 of the California
Financial Code), and shall be delivered free and clear of all liens, claims,
charges and encumbrances of any kind or nature whatsoever, including any
preemptive rights of any stockholder of Issuer.

         (c) Board Action. The performance by Issuer of this Agreement and the
transactions contemplated hereby (including the exercise of the Option) do not
require any approval of the stockholders of Issuer.


                                      4
<PAGE>   149

         6.  Representations and Warranties of Grantee.  Grantee hereby
represents and warrants to Issuer that:

         (a)  Due Authorization.  Grantee has all requisite corporate power and
authority to enter into this Agreement and, subject to any approvals or
consents referred to herein, to consummate the transactions contemplated
hereby.  The execution and delivery of this Agreement and the consummation of
the transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of Grantee.  This Agreement has been duly executed
and delivered by Grantee.

         (b) Purchase Not for Distribution.  This Option is not being, and any
Option Shares or other securities acquired by Grantee upon exercise of the
Option will not be, acquired with a view to the public distribution thereof and
will not be transferred or otherwise disposed of except in a transaction
registered or exempt from registration under the Securities Act.

         7. Adjustment Upon Changes in Capitalization, etc. (a) In the event of
any change in Issuer Common Stock by reason of a stock dividend, stock split,
split up, recapitalization, combination, exchange of shares or similar
transaction, the type and number of shares or securities subject to the Option,
and the Purchase Price therefor, shall be adjusted appropriately, and proper
provision shall be made in the agreements governing such transaction so that
Grantee shall receive, upon exercise of the Option, the number and class of
shares or other securities or property that Grantee would have received in
respect of Issuer Common Stock if the Option had been exercised immediately
prior to such event, or the record date therefor, as applicable. If any
additional shares of Issuer Common Stock are issued after the date of this
Agreement (other than pursuant to an event described in the first sentence of
this Section 7(a)), the number of shares of Issuer Common Stock subject to the
Option shall be adjusted so that, after such issuance, it, together with any
shares of Issuer Common Stock previously issued pursuant hereto, equals 9.9% of
the number of shares of Issuer Common Stock then issued and outstanding,
without giving effect to any shares subject to or issued pursuant to the
Option.  Issuer agrees that in no event shall the number of shares of Issuer
Common Stock issued after the date of this Agreement pursuant to the preceding
sentence, together with the number of shares of Issuer Common Stock subject to
the Option, adjusted as aforesaid, exceed the number of available authorized
but unissued and unreserved shares of Issuer Common Stock.

         (b) In the event that Issuer shall enter into an agreement (i) to
consolidate with or merge into any person, other than Grantee or one of its
Subsidiaries, and shall not be the continuing or surviving corporation of such
consolidation or merger, (ii) to permit any person, other than Grantee or one
of its Subsidiaries, to merge into Issuer and Issuer shall be the continuing or
surviving corporation, but, in connection with such merger, the then
outstanding shares of Issuer Common Stock shall be changed into or exchanged
for stock or other securities of Issuer or any other person or cash or any
other property or the outstanding shares of Issuer Common Stock immediately
prior to such merger shall after such merger represent less than 50% of the
outstanding shares and share equivalents of the merged company, or (iii) to
sell or otherwise




                                      5
<PAGE>   150
transfer all or substantially all of its assets to any person other than
Grantee or one of its Subsidiaries, then, and in each such case, the agreement
governing such transaction shall make proper provisions so that the Option
shall, upon the consummation of any such transaction and upon the terms and
conditions set forth herein, be converted into, or exchanged for, an option
(the "Substitute Option"), at the election of Grantee, of either (A) the
Acquiring Corporation (as defined below), (B) any person that controls the
Acquiring Corporation, or (C) in the case of a merger described in clause (ii),
the Issuer (such person being referred to as the "Substitute Option Issuer").

         (c) The Substitute Option shall have the same terms as the Option,
provided that if the terms of the Substitute Option cannot, for legal reasons,
be the same as the Option, such terms shall be as similar as possible and in no
event less advantageous to Grantee. The Substitute Option Issuer shall also
enter into an agreement with the then holder or holders of the Substitute
Option in substantially the same form as this Agreement, which shall be
applicable to the Substitute Option.

         (d) The Substitute Option shall be exercisable for such number of
shares of the Substitute Common Stock (as is hereinafter defined) as is equal
to the Assigned Value (as is hereinafter defined) multiplied by the number of
shares of the Issuer Common Stock for which the Option was theretofore
exercisable, divided by the Average Price (as is hereinafter defined). The
exercise price of the Substitute Option per share of the Substitute Common
Stock (the "Substitute Purchase Price") shall then be equal to the Purchase
Price multiplied by a fraction in which the numerator is the number of shares
of the Issuer Common Stock for which the Option was theretofore exercisable and
the denominator is the number of shares of the Substitute Common Stock for
which the Substitute Option is exercisable.

         (e) The following terms have the meanings indicated:

         (i)  "Acquiring Corporation" shall mean (A) the continuing or
surviving corporation of a consolidation or merger with Issuer (if other than
Issuer), (B) Issuer in a merger in which Issuer is the continuing or surviving
person, and (C) the transferee of all or any substantial part of the Issuer's
assets (or the assets of its Subsidiaries).

         (ii) "Substitute Common Stock" shall mean the common stock issued by
the Substitute Option Issuer upon exercise of the Substitute Option.

         (iii)  "Assigned Value" shall mean the highest of (A) the price per
share of the Issuer Common Stock at which a tender offer or exchange offer
therefor has been made by any person (other than Grantee), (B) the price per
share of the Issuer Common Stock to be paid by any person (other than the
Grantee) pursuant to an agreement with Issuer, and (C) the highest bid price
per share of Issuer Common Stock as quoted on the principal trading market or
securities exchange on which such shares are traded as reported by a recognized
source within the six-month period immediately preceding the agreement;
provided, however, that in the event of a







                                       6
<PAGE>   151
sale of less than all of Issuer's assets, the Assigned Value shall be the sum 
of the price paid in such sale for such assets and the current market value of
the remaining assets of Issuer as determined by a nationally recognized
investment banking firm selected by Grantee (or by a majority in interest of
the Grantees if there shall be more than one Grantee (a"Grantee Majority")),
divided by the number of shares of the Issuer Common Stock outstanding at the
time of such sale. In the event that an exchange offer is made for the Issuer
Common Stock or an agreement is entered into for a merger or consolidation
involving consideration other than cash, the value of the securities or other
property issuable or deliverable in exchange for the Issuer Common Stock shall
be determined by a nationally recognized investment banking firm mutually
selected by Grantee and Issuer (or if applicable, Acquiring Corporation),
provided that if a mutual selection cannot be made as to such investment
banking firm, it shall be selected by Grantee (or a Grantee Majority).

         (iv) "Average Price" shall mean the average closing price of a share
of the Substitute Common Stock for the one year immediately preceding the
consolidation, merger or sale in question, but in no event higher than the
closing price of the shares of the Substitute Common Stock on the day preceding
such consolidation, merger or sale; provided that if Issuer is the issuer of
the Substitute Option, the Average Price shall be computed with respect to a
share of common stock issued by Issuer, the person merging into Issuer or by
any company which controls or is controlled by such merging person, as Grantee
may elect.

         (f) In no event, pursuant to any of the foregoing paragraphs, shall
the Substitute Option be exercisable for more than 9.9% of the aggregate of the
shares of the Substitute Common Stock outstanding prior to exercise of the
Substitute Option.

         (g) Issuer shall not enter into any transaction described in
subsection (b) of this Section 7 unless the Acquiring Corporation and any
person that controls the Acquiring Corporation assume in writing all the
obligations of Issuer hereunder and take all other actions that may be
necessary so that the provisions of this Section 7 are given full force and
effect (including, without limitation, any action that may be necessary so that
the shares of Substitute Common Stock are in no way distinguishable from or
have lesser economic value than other shares of common stock issued by the
Substitute Option Issuer).

         (h) The provisions of Sections 8 and 9 shall apply, with appropriate
adjustments, to any securities for which the Option becomes exercisable
pursuant to this Section 7 and as applicable, references in such sections to
"Issuer", "Option", "Purchase Price" and "Issuer Common Stock" shall be deemed
to be references to "Substitute Option Issuer", "Substitute Option",
"Substitute Purchase Price" and "Substitute Common Stock", respectively.

         8. Listing. If Issuer Common Stock or any other securities to be
acquired upon exercise of the Option are then authorized for quotation on the
NASDAQ, the New York Stock Exchange (NYSE) or any securities exchange, Issuer,
upon the request of Grantee, will promptly file an application to authorize for
quotation the shares of Issuer Common Stock or other securities to be





                                       7
<PAGE>   152
acquired upon exercise of the Option on the NASDAQ, NYSE or such other
securities exchange and will use its best efforts to obtain approval of such
listing as soon as practicable.

         9. Division of Option.  This Agreement (and the Option granted hereby)
are exchangeable, without expense, at the option of Grantee, upon presentation
and surrender of this Agreement at the principal office of Issuer for other
Agreements providing for Options of different denominations entitling the
holder thereof to purchase in the aggregate the same number of shares of Issuer
Common Stock purchasable hereunder. The terms "Agreement" and "Option" as used
herein include any other Agreements and related Options for which this
Agreement (and the Option granted hereby) may be exchanged. Upon receipt by
Issuer of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Agreement, and (in the case of loss, theft or
destruction) of reasonably satisfactory indemnification, and upon surrender and
cancellation of this Agreement, if mutilated, Issuer will execute and deliver a
new Agreement of like tenor and date. Any such new Agreement executed and
delivered shall constitute an additional contractual obligation on the part of
Issuer, whether or not the Agreement so lost, stolen, destroyed or mutilated
shall at any time be enforceable by anyone.

         10. Miscellaneous. (a) Expenses. Except as otherwise provided in
Section 8, each of the parties hereto shall bear and pay all costs and expenses
incurred by it or on its behalf in connection with the grant or exercise of
this Option, including fees and expenses of its own financial consultants,
investment bankers, accountants and counsel.

         (b) Waiver and Amendment. Any provision of this Agreement may be
waived at any time by the party that is entitled to the benefits of such
provision. This Agreement may not be modified, amended, altered or supplemented
except upon the execution and delivery of a written agreement executed by the
parties hereto.

         (c) Entire Agreement; No Third-Party Beneficiary; Severability. This
Agreement, together with the Merger Agreement and the other documents and
instruments referred to herein and therein (i) constitutes the entire agreement
and supersedes all prior agreements and understandings, both written and oral,
between the parties with respect to the subject matter hereof and (ii) is not
intended to confer upon any person other than the parties hereto any rights or
remedies hereunder. If any term, provision, covenant or restriction of this
Agreement is held by a court of competent jurisdiction or a federal or state
regulatory agency to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.
If for any reason such court or regulatory agency determines that the Option
does not permit Grantee to acquire, or does not require Issuer to repurchase,
the full number of shares of Issuer Common Stock as provided in Sections 3 and
8 (as adjusted pursuant to Section 7), it is the express intention of Issuer to
allow Grantee to acquire or to require Issuer to repurchase such lesser number
of shares as may be permissible without any amendment or modification hereof.

                PART II.  INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.  Indemnification of Directors and Officers.

         The General Corporation Law of the State of Delaware ("DGCL") provides
that a Delaware corporation, such as Comerica Incorporated ("Comerica"), may
indemnify a director or officer against his or her expenses and judgments,
fines and amounts paid in settlement actually and reasonably incurred in
connection with any action, suit or proceeding (other than an action by or in
the right of the corporation) involving such person by reason of the fact that
such person is or was a director or officer, concerning actions taken in good
faith and in a manner reasonably believed to be in or not opposed to the best
interest of the corporation and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful.  The
DGCL also provides that in derivative actions, Comerica may indemnify its
directors and officers against expenses actually and reasonably incurred to the
extent that such directors or officers have been successful on the merits or
otherwise in any such action, suit or proceeding or in the defense of any
claim, issue or matter therein.  Under the DGCL, no indemnification shall be
made with respect to any claim, issue or matter as to which such director or
officer shall have been adjudged to be liable to the corporation unless and
only to the extent that the court shall determine upon application that,
despite the adjudication of liability but in view of all of the circumstances
of the case, such director or officer is fairly and reasonably entitled to
indemnity for such expenses which the court shall deem proper.  The DGCL also
generally permits the advancement of a director's or officer's expenses,
including by means of mandatory charter or Bylaw provision to that effect, in
lieu of requiring the authorization of such advancement by the Board of
Directors in specific cases.  Section 12 of Article V of Comerica's Bylaws
implements such provisions and provides as follows:

                         INDEMNIFICATION AND INSURANCE

         (a)     Comerica shall indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending, or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of Comerica) by reason
of the fact that he or she is or was a Director, officer, employee of Comerica
or is or was serving at the request of Comerica as a Director, officer,
employee or agent of another corporation, partnership, joint venture, trust, or
other enterprise, against expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding if he or she acted in good
faith and in a manner he or she reasonably believed to be in or not opposed to
the best interest of Comerica, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his or her conduct was unlawful.
Any person who is or was an agent of Comerica may be indemnified to the same
extent as hereinabove provided.  In addition, in the event any such action,
suit or proceeding is threatened or instituted against a spouse to whom a
director or officer is legally married at the time such director or officer is
covered under the indemnification provided herein which action, suit or
proceeding arises solely out of his or her status as the spouse of a director
or officer, including, without limitation, an action, suit or proceeding that
seeks damages recoverable from marital community property of the director or
officer and his or her spouse, property owned jointly by them or property
purported to have been transferred from the director or officer to his or her
spouse, the spouse of the director or officer shall be indemnified to the same
extent as hereinabove provided.  The termination of any action, suit, or
proceeding by judgment, order, settlement, conviction or upon a plea of nolo
contendere or its equivalent, shall not, of itself, create a presumption that
the person did not act in good faith and in a manner which he or she reasonably
believed to be in or not opposed to the best interests of Comerica, and, with
respect to any criminal action or proceeding, raise any inference that he or
she had reasonable cause to believe that his or her conduct was unlawful.

         (b)     Comerica shall indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending, or completed
action or suit by or in the right of Comerica to procure a judgment in its
favor by reason of the fact that he or she is or was a Director, officer, or
employee of Comerica, or is or was serving at the request of Comerica as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust, or other enterprise against expenses (including attorneys'
fees) actually and reasonably incurred





                                      II-1
<PAGE>   156
by such person in connection with the defense or settlement of such action or
suit if he or she acted in good faith and in a manner he or she reasonably
believed to be in or not opposed to the best interests of Comerica, and except
that no indemnification shall be made in respect of any claim, issue or matter
as to which such person shall have been adjudged to be liable to Comerica
unless and only to the extent that the court in which such action or suit was
brought shall determine upon application, that despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which the court
shall deem proper.  Any person who is or was an agent of Comerica may be
indemnified to the same extent hereinabove provided.  In addition, in the event
any such action or suit is threatened or instituted against a spouse to whom a
director or officer is legally married at the time such director or officer is
covered under the indemnification provided herein which action or suit arises
solely out of his or her status as the spouse of a director or officer,
including, without limitation, an action or suit that seeks damages recoverable
from marital community property of the director or officer and his or her
spouse, property owned jointly by them or property purported to have been
transferred from the director or officer to his or her spouse, the spouse of
the director or officer shall be indemnified to the same extent as hereinabove
provided.

         (c)     To the extent that a Director, officer, spouse of a Director
or officer, employee or agent of Comerica has been successful on the merits or
otherwise in defense of any action, suit or proceeding referred to in
subsections (a) and (b) of this Section, or in defense of any claim, issue or
matter therein, such person shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by such person in connection
therewith.

         (d)     Any indemnification under subsections (a) and (b) of this
Section (unless ordered by a court) shall be made by Comerica only as
authorized in the specific case upon a determination that indemnification of
the Director, officer, spouse of a Director or officer, employee or agent is
proper in the circumstances because such person has met the applicable standard
of conduct set forth in subsections (a) and (b) of this Section.  Such
determination shall be made (1) by the Board of Directors by a majority vote of
the quorum consisting of Directors who were not parties to such action, suit or
proceeding, or (2) if such a quorum is not obtainable, or even if obtainable a
quorum of disinterested Directors so directs, by independent legal counsel in a
written opinion, or (3) by the stockholders.

         (e)     Expenses (including attorneys' fees) incurred by an officer or
Director, or spouse of an officer or Director, in defending a civil or criminal
action, suit or proceeding may be paid by Comerica in advance of the final
disposition of such action, suit or proceeding upon receipt of an undertaking
by or on behalf of the Director or officer to repay such amount if it shall
ultimately be determined that he or she is not entitled to be indemnified by
Comerica as authorized in this Section.  Such expenses incurred by other
employees and agents may be so paid upon such terms and conditions, if any, as
the Board of Directors deems appropriate.

         (f)     The indemnification and advancement of expenses provided by,
or granted pursuant to, the other subsections of this Section shall not be
deemed exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under any bylaw, agreement, vote of
stockholders or disinterested Directors or otherwise, both as to action in his
or her official capacity and as to action in another capacity while holding
such office.

         (g)     Comerica may purchase and maintain insurance on behalf of any
person who is or was a Director, officer, spouse of a Director or officer,
employee or agent of Comerica, or is or was serving at the request of Comerica
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted against
him and incurred by him in any such capacity, or arising out of his or her
status as such, whether or not Comerica would have the power to indemnify such
person against such liability under the provisions of this Section.

         (h)     For the purpose of this Section, references to "Comerica"
include all constituent corporations absorbed in a consolidation or merger as
well as the resulting or surviving corporation so that any person who is





                                      II-2
<PAGE>   157
or was a director, officer, spouse of a director or officer, employee or agent
of such a constituent corporation or is or was serving at the request of such
constituent corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise shall stand
in the same position under the provisions of this Section with respect to the
resulting or surviving corporation as he or she would if he or she had served
the resulting or surviving corporation in the same capacity.

         (i)     For the purposes of this Section, references to "other
enterprises" shall include employee benefit plans; references to "fines" shall
include any excise taxes assessed on a person with respect to an employee
benefit plan, and reference to "serving at the request of Comerica" shall
include any service as a Director, officer, employee or agent of Comerica which
imposes duties on, or involves services by, such Director, officer, employee or
agent of Comerica with respect to an employee benefit plan, its participants,
or beneficiaries; and a person who acted in good faith and in a manner he or
she reasonably believed to be in the interest of the participants and
beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner "not opposed to the best interests of Comerica" as referred to in this
Section.

         (j)     The indemnification and advancement of expenses provided by,
or granted pursuant to, this Section shall, unless otherwise provided when
authorized or ratified, continue as to a person who has ceased to be a
Director, officer, employee or agent, and with respect to any spouse of a
director or officer, shall continue following the time the director or officer
spouse ceases to be a director or officer even if the marriage of the
individuals terminates prior to the end of the period of coverage, and shall
inure to the benefit of the heirs, executors and administrators of such a
person.

         Section 102(b)(7) of the DGCL provides that a certificate of
incorporation may contain a provision eliminating or limiting the personal
liability of a director to the corporation or its shareholders for monetary
damages for breach of fiduciary duty as a director, provided that such
provision shall not eliminate or limit the liability of a director (i) for any
breach of the director's duty of loyalty to the corporation or its
shareholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) under Section 174
(relating to liability for unauthorized acquisitions or redemptions of, or
dividends on, capital stock) of the DGCL or (iv) for any transaction from which
the director derived an improper personal benefit.  At the 1987 Annual Meeting
of Comerica's shareholders, the shareholders approved an amendment to
Comerica's Restated Certificate of Incorporation to include such a provision.

         Comerica has entered into Indemnification Agreements (the
"Agreements") with each of its directors pursuant to which Comerica agrees (i)
to indemnify each such director to the fullest extent permitted by any
combination of (a) the benefits provided by the indemnification provisions of
Comerica's Bylaws as in effect on the date of such Agreement, (b) the benefits
provided by the indemnification provisions of Comerica's Bylaws in effect at
the time such indemnified costs are incurred by such director, (c) the benefits
allowable under the DGCL in effect at the date of such Agreement or as the same
may be amended (but in the case of any such amendment, only to the extent that
such amendment permits Comerica to provide broader indemnification than such
law permits Comerica to provide prior to such amendment), (d) the benefits
allowable under the law of the jurisdiction under which Comerica is organized
at the time such indemnified costs are incurred by such director, (e) the
benefits available under any Directors' and Officers' Insurance or other
liability insurance obtained by Comerica and (f) the benefits available to the
fullest extent authorized to be provided to such director by Comerica under the
non-exclusivity provisions of the Bylaws of Comerica and the DGCL, against
liabilities and expenses incurred by reason of such person serving as a
director or officer of Comerica or, at Comerica's request, as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise or with respect to employee benefit plans; (ii) to
advance certain expenses to such persons; and (iii) except under certain
circumstances to purchase and maintain in effect one or more Directors' and
Officers' insurance policies.

         No indemnification, reimbursement, or payments are required of
Comerica under the Agreements (except to the extent it is provided from
policies of insurance carried by Comerica):  (1) with respect to any claim as
to which such director shall have been finally adjudged by a court of competent
jurisdiction to (a) have acted in bad





                                      II-3
<PAGE>   158
faith, (b) be liable for acts or omissions which involve intentional
misconduct, a knowing violation of law or of such director's duty of loyalty to
Comerica or its shareholders, (c) have authorized a redemption or dividend on
Comerica's stock which is prohibited by Delaware law or (d) has effected any
transaction from which such director has derived an improper personal benefit
within the meaning of 102(b)(7) of the DGCL, except to the extent that such
court, or another court having jurisdiction, shall determine upon application
that, despite the adjudication of liability, but in view of all the
circumstances of the case, such director is fairly and reasonably entitled to
indemnity for such indemnified costs as the court shall deem proper; (2) with
respect to any payment determined by final judgment of a court, or other
tribunal having jurisdiction over the question, to be unlawful; and (3) with
respect to any obligation of such director under Section 16(b) of the
Securities Exchange Act of 1934, as amended.

         Insurance is maintained on a regular basis (and not specifically in
connection with this offering) against liabilities arising on the part of
director and officers out of their performance in such capacities or arising on
the part of Comerica out of its foregoing indemnification provisions, subject
to certain exclusions and to the policy limits.

Item 22.  Undertakings.

         Insofar as indemnification for liabilities arising under the
Securities Act of 1933 as amended (the "Securities Act") may be permitted to
directors, officers and controlling persons of Comerica pursuant to the
provisions described in Item 20 or otherwise, Comerica has been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act of 1933 and is,
therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by Comerica of expenses
incurred or paid by a director, officer or controlling person of Comerica 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, Comerica will, unless in the opinion of its counsel the matter has
been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act of 1933 and will be governed by the
final adjudication of such issue.

         The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act
of 1934) that is incorporated by reference in the registration statement shall
be deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

         The undersigned registrant hereby undertakes as follows:  that prior
to any public reoffering of the securities registered hereunder through use of
a prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

         The undersigned registrant undertakes that every prospectus (i) that
is filed pursuant to the foregoing paragraph, or (ii) that purports to meet the
requirements of Section 10(a)(3) of the Securities Act and is used in
connection with an offering of securities subject to Rule 415, will be filed as
a part of an amendment to the registration statement and will not be used until
such amendment is effective, and that, for purposes of determining any
liability under the Securities Act, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

         The undersigned registrant hereby undertakes to respond to requests
for information that is incorporated by reference into the prospectus pursuant
to Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means.  This includes information contained in documents
filed subsequent to the effective date of the registration statement through
the date of responding to the request.

         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.

         The undersigned registrant hereby undertakes:

         (1)     To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement:





                                     II-7
<PAGE>   162
         (i)     To include any prospectus required by Section 10(a)(3) of the
         Securities Act;

         (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
         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.

         (2)     That for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3)     To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

           [MILLER CANFIELD, PADDOCK AND STONE, P.L.C. LETTERHEAD]

                              December 19, 1994

Comerica Incorporated                     University Bank & Trust Company
Corporate Secretary -                     250 Lytton Avenue

Gentlemen:

        We have acted as counsel to Comerica Incorporated, a Delaware
corporation and bank holding company ("Comerica"), in connection with the       
contemplated merger (the "Merger") of Comerica Interim Incorporated, a
California corporation and a wholly-owned subsidiary of Comerica ("Interim")
with and into University Bank & Trust Company, a California bank ("UBT"),
pursuant to an Agreement and Plan of Reorganization and Merger, dated as of
October 4, 1994, by and among UBT, Interim and Comerica (the "Merger
Agreement").

       This opinion has been delivered in connection with Section 7.1.6 of the
Merger Agreement.  All capitalized terms used herein, unless otherwise
specified, have the meanings assigned to them in the Merger Agreement.

       In rendering our opinion, we have examined and relied upon the accuracy
and completeness of the facts, information, covenants and representations
contained in originals or copies, certified or otherwise identified to our
satisfaction, of the Merger Agreement, and such other documents as we have
deemed necessary or appropriate as a basis for the opinion set forth below.  In
addition, we have relied upon the facts contained in certain statements and
representations made by executives of Comerica.  We also have assumed that the
Merger will be consummated in accordance with the Merger Agreement.  In
addition, we have relied upon, without independent investigation, and our
opinion is conditioned upon the accuracy of the representations made to us set
forth in a subsequent part of this letter.  We have relied upon, without
independent investigation, and our opinion is conditioned upon, among other
things, the initial accuracy of such facts, information, covenants, statements
and representations as well as
<PAGE>   2

the absence of any change in the foregoing material to this opinion between the
date of this opinion and the Closing Date.

       Finally, we have relied upon and this opinion is conditioned on the
accuracy of the representations contained in the attached Representation
Certificates from UBT and from Comerica and Interim as being true in all
material respects as of the date hereof.  These Representation Certificates are
attached hereto as Exhibit A and B, respectively.

       In rendering our opinion, we have considered the applicable provisions
of the Internal Revenue Code of 1986, as amended (the "Code"), Treasury
Regulations promulgated thereunder, pertinent judicial authorities,
interpretive rulings of the Internal Revenue Service and such other authorities
as we have considered relevant.  It should be noted that statutes, regulations,
judicial decisions and administrative interpretations are subject to change at
any time and, in some circumstances, with retroactive effect.  A material
change in the authorities upon which our opinion is based could affect our
conclusions.  However, we assume no obligation to revise or supplement this
opinion if any subsequent change were to occur.

OPINION

       Based solely upon the foregoing, we are of the opinion that under
current law:

                 (i)    the Merger will be treated as a reorganization within
          the meaning of Section 368(a)(1)(A) and 368(a)(2)(E) of the Code, and
          Comerica, UBT and Interim each will be a party to the reorganization
          within the meaning of Section 368(b) of the Code;

                 (ii)   no gain or loss will be recognized by Comerica, UBT or
          Interim as a consequence of the Merger.

       The tax consequences described above may not be applicable to a
shareholder who received UBT Common Stock pursuant to exercise of an employee
stock option or otherwise as compensation.

       Except as set forth above, we express no opinion to any party as to the
tax consequences, whether federal, state, local or foreign, of the Merger, or
of any transactions related thereto.  We are furnishing this opinion to you
solely in connection with Section 7.1.6 of the Merger Agreement; this opinion
is solely for

                                     -2-

your benefit and is not to be used, circulated, quoted or otherwise referred to
for any purpose without our express written permission.

       We hereby consent to the references made to us under the heading "THE
MERGER -- Certain Federal Income Tax Consequences" in the Proxy
Statement/Prospectus of Comerica and UBT and to the filing of this opinion as
Exhibit (8) to the Registration Statement on Form S-4 of Comerica.  In giving

                           NON-COMPETITION AGREEMENT


         This Agreement is entered into as of ___________________, 1995 by and
between University Bank and Trust Company, a California corporation, (the
"Company") and Carl J. Schmitt ("Officer").

                                    RECITALS

         WHEREAS, due to the position of Officer with the Company and his
knowledge of information concerning the Company and its business, the Company
desires to restrict Officer's ability to compete with the Company;

         NOW THEREFORE, in consideration of these circumstances, the parties
have entered into this Agreement on the terms set forth below for valuable
consideration, the adequacy and receipt of which is hereby acknowledged.

   
         Compensation.  The Company hereby agrees to pay the Officer, whether 
or not Officer is an officer, director, or employee of, or a consultant to, the 
Company, the sum of $1,239,185 (less applicable withholding) upon 
execution of this Agreement.  Any payments due under this Agreement shall not 
be offset by any compensation or other remuneration due or which becomes due 
to Officer after the date of this Agreement.
    

         1.      Character of Payments.  The Company and Officer agree and
acknowledge that the payment due Officer hereunder is in consideration of
Officer's refraining from competing with the Company for the period specified
in this Agreement.  Such payment shall be treated as ordinary income to Officer
by company and Officer on their tax returns.

      2.      Non-Disclosure of Confidential Information.  
    
              (a)      Except as authorized in writing by the Company, the 
      Officer shall not at any time, disclose or use, directly or indirectly, 
      confidential information of the Company which the Officer has gained 
      knowledge of by reason of said employment, and the Officer shall 
      retain all such information in trust in a fiduciary capacity for the 
      sole use and benefit of the Company. Such confidential information 
      includes, but is not limited to, information of the Company whether 
      now owned or hereafter obtained, concerning marketing and sale methods,
      materials, processes, procedures, devices, computer programs, computer 
      software, fringe benefit programs or any other process or procedures 
      utilized by the Company.  Such confidential information shall also 
      include but is not limited to products distributed by the Company or 
      its distributors, products manufactured and/or sold by the Company 
      business forms, computer programs, computer software, prices, list of
      suppliers and customers, plans for new areas or markets, internal 
      operations and any patents, improvements, ideas, variations, trade 
      secrets, proprietary information and other confidential information of 
      any type, together with all written, graphic and other materials 
      relating to all or any part of the same.  The Officer acknowledges 
      that the confidential information of the Company is valuable, 
      special and unique to the Company's business and on which the
      Company's business depends, and is proprietary to the Company, and 
      that the Company wishes to protect said confidential information by 
      keeping it secret and confidential for its sole use and benefit.  The 
      Officer will take all reasonable steps necessary, and all reasonable 
      steps requested by the Company, to insure that all such confidential 
      information is kept secret and confidential for the sole use and 
      benefit of the Company.
<PAGE>   3

                 (b)      Upon termination of the Officer's employment with the
         Company, or any other time the Company may in writing so request, the
         Officer shall promptly deliver to the Company all materials concerning
         any confidential information, copies thereof and any other material of
         the Company which are in the possession or under the control of the
         Officer.  The Officer shall not make or retain any copy or extract
         thereof.

   
         3.      Non-Compete.  At any time that the Officer is employed by the
Company, and for a period of five years after termination of the
Officer's employment the Company, the Officer shall not:
    

                 (a)      solicit, cause, induce or encourage, directly or
         indirectly, any employee of the Company to leave its employ, or any
         independent contractor to terminate any independent contractor
         relationship with the Company;

                 (b)      cause, induce or encourage, directly or indirectly,
         any customer or client of the Company to terminate or adversely change
         any relationship with the Company;

                 (c)      cause, induce or encourage any potential supplier or
         customer to not enter into any business relationship with the Company;

   
                 (d)      directly or indirectly, including but not by way of
         limitation, as an owner, employee, employer, operator, investor,
         independent contractor, agent, stockholder, partner (general or
         limited), joint venturer, officer, director, consultant, franchisee,
         franchiser or co-worker, enter into, conduct participate or engage in
         any form of business in the counties of Santa Clara and Santa Cruz 
         in the State of California, which are related to or operates a bank, 
         bank holding company, savings and loan association, savings bank or 
         other financial institution.
    
<PAGE>   4
         4.      The Officer shall disclose to the Company all inventions,
discoveries, variations, computer programs, ideas and improvements, whether or
not copyrightable or patentable, conceived or made by the Officer alone or
jointly with other during the Officer's employment with the Company, related to
the business or activities of the Company or resulting asks assigned by the
Company and assigns and agrees to assign all the Officer's interest therein to
the Company as the sole exclusive property of the Company.  The Officer shall
execute such documents and do such acts as shall be necessary to perfect the
Company's rights therein.  These obligations shall continue after termination
of the Officer employment with the Company with respect to all inventions,
discoveries, variations, ideas and improvements conceived or made by the
Officer during the term of said employment.

         5.      It is expressly understood and agreed that although the
Officer and Company consider the restrictions contained in Sections 3, 4 and 5
above reasonable for the purpose of preserving for the Company goodwill,
proprietary rights and going concern value, if a final judicial determination
is made by a court having jurisdiction that the time or territory or any other
restriction contained in these paragraphs is an unenforceable restriction on
the activities of the Officer, the provisions of these paragraphs shall not be
rendered void but shall be deemed amended to apply as to such maximum time and
territory and to such other extent as such court may judicially determine or
indicate to be reasonable.  Alternatively, if the court  referred to above
finds that any restriction contained in these paragraphs is unenforceable, and
such restriction cannot be amended so as to make it enforceable, such finding
shall not affect the enforceability of any of the other restrictions contained
herein.
<PAGE>   5
         6.      Binding Effect.  This Agreement shall be binding upon and
shall inure to the benefit of Officer and his heirs and legal representatives,
and the Company and their respective successors and permitted assigns.

         7.      Enforcements.

         (a)     Damages Inadequate.  In the event of a threatened or actual
breach of Sections 3, 4 and 5 of the Agreement by the Officer, it is agreed and
acknowledged that damages would not be an adequate remedy to compensate the
Company of the loss of goodwill and other harm to the business of the Company.

         (b)     Injunctive Relief.  In the event of a threatened or actual
breach of Section 3, 4 and 5 of this Agreement by the Officer, the Company
shall be entitled to a temporary restraining order, and to temporary and
permanent injunctive relief, to prevent or terminate such anticipated or actual
breach, provided that nothing in this Agreement shall be construed to limit the
damages otherwise recoverable by the Company in any such event.

         (c)     Notice to Third Parties.  In addition, after discussing the
matter with the Officer, the Company shall have the right, subject to
applicable law, to inform any other third party that the Company reasonably
believes to be, or to be contemplating, participating with the Officer or
receiving from the Officer assistance in violation of this Agreement, of the
terms of this Agreement and of the rights of the Company hereunder, and that
participation by any such entity or persons with the Officer in activities in
violation of this Agreement may give rise to claims by the Company against such
entity, persons or third party.

         8.      Assignment.  The Company may assign its rights and benefits
under this Agreement to any person, firm, partnership, corporation,
association, or other entity to which may be transferred all or a part of the
businesses of the Company or its subsidiaries, in the aggregate, 
<PAGE>   6
and/or a majority of the outstanding capital stock of the Company or its 
subsidiaries, in the aggregate, in which even the covenants, duties, 
obligations and agreements on the part of Officer contained in this Agreement
shall inure to the benefit of any such transferee or other successor to the
same extent and with the same force and effect as if this Agreement had been
entered into by Officer directly with such transferee or other successor.  The
obligations of Officer under this Agreement are personal as to Officer and may
not be transferred or delegated by Officer to any person, either voluntarily or
involuntarily, but Officer shall be entitled to assign his rights to receive
payments hereunder and such rights shall inure to the benefit of Officer's
estate in the event of his death in the absence of any prior assignment. Except
as specifically provided herein, this Agreement is not intended to, and shall
not, confer any rights or benefits upon any person or entity that is not a
party hereto.

         9.      Waiver of breach.  The waiver by any party hereto of a breach
of any provision of this Agreement shall not operate or be construed as a
waiver of any subsequent breach by any party.

         10.     Captions.  The various titles of the paragraphs herein are
used solely for convenience and shall not be used for interpretation or
construing any word, clause, paragraph or subparagraph of this Agreement.

         11.     Governing law.  This Agreement shall be construed and
interpreted according to the laws of the State of California.

                         NOTES TO FINANCIAL STATEMENTS

                          Quarter ended March 31, 1994


The financial statements included herein are unaudited.  The information
furnished herein reflects all adjustments which are, in the opinion of
management, necessary to a fair statement of the results of the interim period
ended March 31, 1994.


NOTE A - Summary of Significant Accounting Policies

Investment Securities

The Bank adopted Statement of Financial Accounting Standards No. 115,
"Accounting for Certain Investments in Debt and Equity Securities" as of
December 31, 1993.  The Bank has classified its investment securities as
available for sale.  Available for sale securities are reported at fair value,
with unrealized gains and losses, net of taxes, reported as a separate
component of shareholders' equity.  Amortization of premiums and accretion of
discounts arising at acquisition of investment securities are included in
income using methods that approximate the interest method.

Loans

Loans are stated net of undisbursed funds.  Interest on commercial, consumer
installment and real estate loans is accrued on a simple interest basis.
Interest on loans is not accrued in those instances where management considers
principal amounts doubtful of collection.

Loan Fees

Nonrefundable fees for loan origination and commitments in excess of direct
costs of originating the loan or commitment are amortized over the life of the
loan using the straight line method.  Fees originated since 1988 are recognized
as income using the interest method as required by FASB 91.

Allowance for Loan Losses

The allowance for loan losses is established through charges to earnings in the
form of a provision for loan losses.  Loans which are determined to be
uncollectible are charged against this allowance, and subsequent recoveries, if
any, are credited to the allowance.

The allowance for loan losses is an amount that management believes will be
adequate to absorb possible losses on existing loans that 



                                       8
<PAGE>   9

may become uncollectible, based on evaluations of the collectability of
loans and prior loan experience.  The evaluations take into consideration such
factors as changes in the nature and volume of specific problem loans and
current or anticipated economic conditions that may affect the borrowers'
ability to pay.

Premises and Equipment

Premises and equipment are stated at cost, less accumulated depreciation and
amortization.  Depreciation is computed using the straight line method over
estimated useful lives of the assets.

Income Per Share of Common Stock

Net income per share is based upon the weighted average number of common shares
outstanding adjusted by the dilutive effect of stock options outstanding on a
fully diluted basis.

NOTE B - Provision for Income Taxes

No portion of income tax provision is attributable to foreign operations.  The
provision for income tax has been calculated taking into account the tax-exempt
status of portions of municipal bond income.  Of the federal statutory income
tax rate of 34%, the following are the components of the current quarter
provision:

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

Capital

During the first quarter of 1994, the Bank's capital increased by $4,460,518,
or 13.15%, compared to an increase of $1,041,456, or 13.15% in the same period
of 1993.  $1,588,119, or 35.60%, of the increase in the current quarter was
caused by the adoption of SFAS 115, "Accounting for Certain Investments in Debt
and Equity Securities" as of December 31, 1993 which is discussed elsewhere in
this report.  Additional sources of additional capital in each of the periods
were retained earnings, exercise of stock options and purchases of new stock by
the Bank's profit sharing and 401K plans.  The Bank paid a dividend of
thirty-five cents a share to shareholders of record January 17, 1994, or a
total of $473,539 compared to a dividend of thirty-five cents per share, or a
total of $466,285 in the same period of 1993.  Dividend payments continued on a
quarterly basis in 1993 and 1994.

The Bank is subject to Office of the Comptroller of the Currency's regulations.
In 1989, the Comptroller established risk-based capital guidelines for national
banks.  The Federal Reserve Board and the FDIC have issued similar guidelines
for bank holding companies and state banks.  The guidelines define Tier 1
Capital and Total Capital.  Tier 1 Capital consists of common and qualifying
preferred shareholders' equity and minority interests in equity accounts of
consolidated subsidiaries.  Total Capital consists of, in addition to Tier 1
Capital, mandatory convertible debt, preferred stock not qualifying as Tier 1
Capital, subordinated debt and other qualifying term debt and a portion of the
allowance for loan losses less the remaining 50% of investments in
unconsolidated subsidiaries.  The Tier 1 component must comprise at least 50%
of qualifying Total Capital.  Risk-based capital ratios are calculated with
reference to risk-weighted assets which include both on and off-balance sheet
exposures.  The minimum required qualifying total capital ratio is 8%, of which
at least 4% must consist of Tier 1 Capital.  At March 31, 1994, the Bank's Tier
1 Capital totaled $32,339,000 and Total Capital was $35,661,000.  The Bank's
Tier 1 capital to total risk weighted assets ratio was 12.29% and its Total
Capital to total risk weighted assets ratio was 13.56%.

It is the intention of the Bank to continue capital augmentation through
earnings retention net of dividends in future years.

Liquidity

Historically, the Bank's balance sheet has shown a high degree of liquidity.
The following table shows balance sheet proportions for the quarter ending
March 31, 1994 and for the years ending December 31, 1993 and December 31,
1992.

Totals may not add due to rounding.

  Bank assets containing a high degree of liquidity are Cash & Due From Banks,  
  Investment Securities and Federal Funds Sold.  For the quarter ending March
  31, 1994, those assets comprised 42.51% of the Bank's assets compared to
  35.45% in 1993 and 33.80% in 1992.

  A principal source of liquidity is new deposit generation.  Historically, 
  loan generation had lagged deposit growth.  The loan to deposit ratio 
  decrease from 66.50% in 1992 to 65.15% in 1993 and to 57.36% in the first 
  quarter of 1994. Loans decreased by 4.73% in the first quarter of 1994.  
  Growth rates for the first quarter of 1994 and for the years 1993 and 1992 
  are shown in the following table.

The investment portfolio is another source of liquidity.  While a portion of
the portfolio is intended to be a permanent investment, a portion is invested
in short-term obligations pending re-employment of these funds in the loan
portfolio or for deposit withdrawals.  As of March 31, 1994, book value of the
investment 


                                      11
<PAGE>   12
portfolio totaled $108,370,327.  Of that amount, $61,204,694, or 56.48%
of the total portfolio matures  within one year.  Additionally, the securities
in the portfolio are freely marketable.  The portfolio contains $2,691,727 in
unrealized appreciation.

Within the loan portfolio are investments in short term bankers' acceptances
totaling $8,869,862 at March 31, 1994.  These acceptances all mature within 180
days.

Other internal sources of liquidity are the retention of earnings and cash flow
generated in the loan portfolio.

External sources of liquidity include borrowings available to the Bank.  As of
March 31, 1994, the Bank has two lines available totaling $10,000,000 of which
$5,000,000 is committed until June 30, 1994, and on which commitment fees have
been paid.  $5,000,000 is on an "as available" basis.

Indebtedness of Management

The Bank has had, and expects to have in the future, banking transactions in
the ordinary course of its business with directors, officers, principal
shareholders and their associates, on the same terms, including interest rates
and collateral on loans, as those prevailing at the same time for comparable
transactions with others, and which, in the opinion of the Bank's Management,
do not involve a greater risk of collectibility.  Furthermore, it is the Bank's
policy to preclude its executive officers, with the exception of the Chairman
of the Board, from borrowing from the Bank and any loan to the Chairman or a
director must be approved by the entire Board of Directors.

The following table summarizes the loans to Directors and Principal Holders of
Equity Securities in the quarter ended March 31, 1994:

by $47.3 million or 13.15% over the first quarter 1993 and increased by $12.7
million, or 3.21%, over the fourth quarter of 1993.  Deposits and other
borrowings increased $43.8 million, or 13.31% over the first quarter of 1993
and increased $13.8 million, or 3.85% over the fourth quarter of 1993.

The mix in earning assets reflects a decrease in loan demand.  Loans, net of
bankers' acceptances, as a percent of earning assets were 71.31% for the
quarter ended March 31, 1993, 63.39% for the fourth quarter of 1993 and 60.25%
for the current quarter.

Net Interest Income and Margin

In the three months ended March 31, 1994, net interest income on a fully
taxable equivalent basis decreased $47,000, or 1.05% from the preceding quarter
and decreased $176,000, or 3.84%, over the same period in 1993.

Interest-earning assets averaged $363.9 million, an increase of $43.5 million,
or 13.59%, over the same period in 1993.  Interest earned on those assets
decreased $178,000, or 2.87%, for a total of $6,017,000 in this period.  The
composite fully taxable equivalent yield on interest-earning assets decreased
from 7.84% in the first quarter of 1993 to 6.71% in the current period.
Compared with the preceding period, interest on earning assets decreased
$178,000, or 2.87%.  Yields decreased one hundred thirteen basis points from
7.84% to 6.71%. 

Average interest-bearing liabilities increased by $43.8
million to $372.7 million, or 13.31% over the same period in 1993.  Interest
expense decreased $2,000, or 0.12%.  The composite average cost of funds
decreased from 1.98% to 1.75%.  In this quarter, compared to the prior quarter,
the cost of funds increased by two basis points from 1.73% to 1.75%.  Net
interest margin decreased from 5.81% in the first quarter of 1993 to 5.06% in
the fourth quarter of 1993 and to 4.91% in the current quarter.

Non-Interest Income

In this period, non-interest income increased $118,026, or 13.67% over the same
period in 1993 and increased $46,100, or 5.03% from the prior period.
Non-interest income is derived from Trust Department fees, service charges on
deposit accounts, other fees and charges and safe deposit rentals.  In this
period, trust fees accounted for $667,500 or 69.31% of non-interest revenue.
Increases in non-interest income over the prior year are due to increased
volume of trust business.

Non-Interest Expense


Non-interest expense increased $328,600, or 9.95%, in this period compared to
the same period in 1993, and increased $56,400 or 1.58% over the prior period.
Overall increases in non-interest expense are due to increases in deposits and
earning assets and increased 


                                      13

staff and other costs necessary to service this growth.  Total FTE increased by
15.95 positions, or 12.63%, to 142.25 from the first quarter of 1993 to the
current quarter.

Provision for Loan and Lease Losses

The Bank provided $300,000 for loan losses in this period compared to $300,000
in the first quarter of 1993 and to $1,732,800 in the fourth quarter of 1993.
The Bank's Reserve for Loan Losses is maintained at a level that Management
believes will be adequate to absorb possible losses. Management evaluations
take into consideration such factors as changes in the nature and volume of
specific problem loans and current economic conditions that may affect the
borrower's ability to repay.

The balance of the reserve for loan losses was $5,976,175 at March 31, 1994
compared to $5,690,341 at December 31, 1993 and to $3,835,096 at March 31,
1993.  Net losses totaled $14,167 in the first quarter of 1994 compared to
$146,967 in the first quarter of 1993 and to $86,697 in the fourth quarter of
1993.

Loans on non-accrual totaled $3,905,956 at March 31, 1994 compared to
$4,084,400 at March 31, 1993 and to $3,814,202 at December 31, 1993.  The
volume of non-accrual loans is due to deterioration in the local economy,
particularly in real estate.

Investment Portfolio

The Bank adopted SFAS No. 115, "Accounting for Certain Investments in Debt &
Equity Securities," as of December 31, 1993.  SFAS requires entities to
classify investments in debt securities and equity securities with readily
determinable fair values as held to maturity, available for sale, or trading
and establishes accounting and reporting requirements for each classification.
The Bank has classified all of its investments as available for sale as it does
not have the intent to hold such securities until maturity.  Available for sale
securities are reported at fair value, with unrealized gains and losses, net of
taxes, reported as a separate component of shareholders' equity.  At March 31,
1994, this separate component of equity was $1,588,119.

The portfolio increased by $34,991,447, or 47.69% to $108,370,327 book value
from March 31, 1993 to March 31, 1994.  Large deposit generation coupled with
low loan demand created excess liquidity.

Letters of Credit

At March 31, 1994, the Bank's commitments under unused letters of credit were
$4,417,800 of which 20% are reasonably expected to be exercised within the next
twelve months.  At March 31, 1993, such commitments totaled $7,897,000 and at
December 31, 1993, $5,139,135.

INTEREST RATES AND NET INTEREST DIFFERENTIAL

The major portion of the Bank's income results from the difference between
interest income derived from earning assets and interest expense paid on
liabilities incurred primarily for the funding of those assets.  The
difference is referred to as net interest income.  Net interest income
expressed as a percent of average total earning assets is referred to as net
interest margin.  Net interest income and net interest margin are summarized
in the following comparisons for the three months ended March 31, 1994 over
the same period in 1993 and for the three months ended December 31, 1993.
Average balances are expressed in thousands of dollars:

The financial statements included herein are unaudited.  The information
furnished herein reflects all adjustments which are, in the opinion of
management, necessary to a fair statement of the results of the interim period
ended June 30, 1994.


NOTE A - Summary of Significant Accounting Policies

Investment Securities

The Bank adopted Statement of Financial Accounting Standards No. 115,
"Accounting for Certain Investments in Debt and Equity Securities" as of
December 31, 1993.  The Bank has classified its investment securities as
available for sale.  Available for sale securities are reported at fair value,
with unrealized gains and losses, net of taxes, reported as a separate
component of shareholders' equity.  Amortization of premiums and accretion of
discounts arising at acquisition of investment securities are included in
income using methods that approximate the interest method.

Loans

Loans are stated net of undisbursed funds.  Interest on commercial, consumer
installment and real estate loans is accrued on a simple interest basis.
Interest on loans is not accrued in those instances where management considers
principal amounts doubtful of collection.

Loan Fees

Nonrefundable fees for loan origination and commitments in excess of direct
costs of originating the loan or commitment are amortized over the life of the
loan using the straight line method.  Fees originated since 1988 are recognized
as income using the interest method as required by FASB 91.

Allowance for Loan Losses

The allowance for loan losses is established through charges to earnings in the
form of a provision for loan losses.  Loans which are determined to be
uncollectible are charged against this allowance, and subsequent recoveries, if
any, are credited to the allowance.


                                      9
<PAGE>   29
The allowance for loan losses is an amount that management believes will be
adequate to absorb possible losses on existing loans that may become
uncollectible, based on evaluations of the collectability of loans and prior
loan experience.  The evaluations take into consideration such factors as
changes in the nature and volume of specific problem loans and current or
anticipated economic conditions that may affect the borrowers' ability to pay.

Premises and Equipment

Premises and equipment are stated at cost, less accumulated depreciation and
amortization.  Depreciation is computed using the straight line method over
estimated useful lives of the assets.

Income Per Share of Common Stock

Net income per share is based upon the weighted average number of common shares
outstanding adjusted by the dilutive effect of stock options outstanding on a
fully diluted basis.

NOTE B - Provision for Income Taxes

No portion of income tax provision is attributable to foreign operations.  The
provision for income tax has been calculated taking into account the tax-exempt
status of portions of municipal bond income.  Of the federal statutory income
tax rate of 34%, the following are the components of the current quarter
provision:

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

Capital

During the second quarter of 1994, the Bank's capital increased by $371,456, or
1.10%, compared to an increase of $723,219, or 2.45% in the same period of
1993.  Without the effect of the adoption of SFAS 115, "Accounting for Certain
Investments in Debt and Equity Securities" as of December 31, 1993, this
increase was $987,655 or 3.05%.  Sources of additional capital in each of the
periods were retained earnings, exercise of stock options and purchases of new
stock by the Bank's profit sharing and 401K plans.  The Bank paid a dividend of
thirty-five cents a share to shareholders of record April 13, 1994, or a total
of $478,131.  A dividend of $.35 per share, totaling $466,845 was paid in the
second quarter of 1993.  Dividend payments continued on a quarterly basis in
1993 and 1994.

The Bank is subject to the Federal Reserve Bank's regulations.  In 1989, the
Federal Reserve Bank established risk-based capital guidelines for member
banks.  The Comptroller of the Currency and the FDIC have issued similar
guidelines for national banks.  The guidelines define Tier 1 Capital and Total
Capital.  Tier 1 Capital consists of common and qualifying preferred
shareholders' equity and minority interests in equity accounts of consolidated
subsidiaries.  Total Capital consists of, in addition to Tier 1 Capital,
mandatory convertible debt, preferred stock not qualifying as Tier 1 Capital,
subordinated and other qualifying term debt and a portion of the allowance for
loan losses less the remaining 50% of investments in unconsolidated
subsidiaries.  The Tier 1 component must comprise at least 50% of qualifying
Total Capital.  Risk-based capital ratios are calculated with reference to
risk-weighted assets which include both on and off-balance sheet exposures.
The minimum required qualifying total capital ratio is 8%, of which at least 4%
must consist of Tier 1 Capital.  At June 30, 1994, the Bank's Tier 1 Capital
totaled $33,427,000 and Total Capital was $36,844,000.  The Bank's Tier 1
capital to total risk weighted assets ratio was 12.23% and its Total Capital to
total risk weighted assets ratio was 13.48%.

It is the intention of the Bank to continue capital augmentation through
earnings retention net of dividends in future years.

Liquidity
   
Historically, the Bank's balance sheet has shown a high degree of liquidity. 
The following table shows balance sheet proportions for the quarter ending June
30,1994 and for the years ending December 31, 1993 and December 31, 1992.

Totals may not add due to rounding.

Bank assets containing a high degree of liquidity are Cash & Due From Banks,
Investment Securities and Federal Funds Sold.  For the quarter ending June 30,
1994, those assets comprised 43.07% of the Bank's assets compared to 34.83% in
1993 and 33.80% in 1992.

A principal source of liquidity is new deposit generation.  Historically, loan
generation has periodically lagged deposit growth.  The loan to deposit ratio
decreased from 66.50% in 1992 to 65.15% in 1993 and to 56.40% in the second
quarter of 1994.  Growth rates for the second quarter of 1994 and for the years
1993 and 1992 are shown in the following table.

                                      12
<PAGE>   32
The investment portfolio is another source of liquidity.  While a portion of
the portfolio is intended to be a permanent investment, a portion is invested
in short-term obligations pending re-employment of these funds in the loan
portfolio or for deposit withdrawals.  As of June 30, 1994, the investment
portfolio totaled $97,874,455.  Of that amount, $1,425,254, or 1.46% of the
total portfolio matures  within one year.  Additionally, the securities in the
portfolio are freely marketable.  The portfolio contains $1,476,300 in
unrealized appreciation.

Within the loan portfolio are investments in short term bankers acceptances
totaling $11,820,900 at June 30, 1994.  These acceptances all mature within 180
days.

Other internal sources of liquidity are the retention of earnings and cash flow
generated in the loan portfolio.

External sources of liquidity include borrowings available to the Bank.  As of
June 30, 1994, the Bank has two lines available totaling $10,000,000 of which
$5,000,000 is committed until June 30, 1995, and on which commitment fees have
been paid.  $5,000,000 is on an "as available" basis.

Indebtedness of Management

The Bank has had, and expects to have in the future, banking transactions in
the ordinary course of its business with directors, officers, principal
shareholders and their associates, on the same terms, including interest rates
and collateral on loans, as those prevailing at the same time for comparable
transactions with others, and which, in the opinion of the Bank's Management,
do not involve a greater risk of collectibility.  Furthermore, it is the Bank's
policy to preclude its executive officers, with the exception of the Chairman
of the Board, from borrowing from the Bank and any loan to the Chairman or a
director must be approved by the entire Board of Directors.

The following table summarizes the loans to Directors and Principal Holders of 
Equity Securities in the quarter ended June 30, 1994:

Outstanding Balances as of March 31, 1994             $1,068,472.91

Aggregate Amount of New Loans Made                         -0-

Aggregate Amount of Repayments                           269,186.46

Aggregate Amount of Other Changes                        916,916.05

Aggregate Amount of Outstandings at June 30, 1994     $1,716,202.50

During the period ended June 30, 1994, none of these loans became past due or
was placed on non-accrual.

Results of Operations

In the quarter ended June 30, 1994, average daily assets increased



                                      13
<PAGE>   33
by $34.7 million or 9.20% over the second quarter 1993 and increased by $5.1
million, or 1.24%, over the first quarter of 1994.  Deposits and other
borrowings increased $32.5 million, or 9.37% over the second quarter of 1993
and increased $6.2 million, or 1.67% over the first quarter of 1994.

The mix in earning assets reflects a decrease in loan demand.  Loans, net of
banker's acceptances, as a percent of earning assets were 59.28% for the
quarter ended June 30, 1994, compared to 68.26% for the second quarter of 1993
and 60.25% for the first quarter of 1994.

Net Interest Income and Margin

In the three months ended June 30, 1994, net interest income on a fully taxable
equivalent basis increased $521,000, or 11.81% from the preceding quarter and
increased $270,000, or 5.79%, over the same period in 1993.

Interest-earning assets averaged $370.1 million, an increase of $32.3 million,
or 9.55%, over the same period in 1993.  Interest earned on those assets
increased $396,000, or 6.29%, for a total of $6,694,000 in this period.  The
composite fully taxable equivalent yield on interest- earning assets decreased
from 7.48% in the second quarter of 1993 to 7.25% in the current period.
Compared with the preceding period, interest on earning assets increased
$677,000, or 11.25%.  Yields increased fifty four basis points from 6.71% to
7.25%.

Average interest-bearing liabilities increased by $32.5 million to $378.9
million, or 9.37% over the same period in 1993.  Interest expense increased
$126,000, or 7.07%.  The composite average cost of funds decreased from 1.90%
to 1.87%.  In this quarter, compared to the prior quarter, the cost of funds
increased by twelve basis points from 1.75% to 1.87%.  Net interest margin
decreased from 5.53% in the second quarter of 1993 to 4.91% in the first
quarter of 1994 and increased to 5.34% in the current quarter.

Non-Interest Income

In this period, non-interest income decreased $16,000, or 1.85% over the same
period in 1993 and decreased $120,000, or 12.40% from the prior period.
Non-interest income is derived from Trust Department fees, service charges on
deposit accounts, other fees and charges and safe deposit rentals.  In this
period, trust fees accounted for $581,000 or 68.51% of non-interest revenue.
Decreases in non-interest income over the prior quarter are due to decreased
market value of trust assets upon which those fees are based.

Non-Interest Expense

Non-interest expense increased $408,000, or 12.32%, in this period compared to
the same period in 1993, and increased $87,000 or 2.40% over the prior period.
Overall increases in non-interest expense are due to increases in deposits and
earning assets and increased

staff and other costs necessary to service this growth.

Provision for Loan and Lease Losses

The Bank provided $100,000 for loan losses in this period compared to $300,000
in the second quarter of 1993 and to $300,000 in the first quarter of 1994.
The Bank's Reserve for Loan Losses is maintained at a level that Management
believes will be adequate to absorb possible losses. During this quarter, the
Bank adopted a new loan loss adequacy policy to conform to the new federal
guidelines "Interagency Policy Statement on the Allowance for Loan and Lease
Losses (ALLL)" which was issued December 21, 1993.  Management evaluations take
into consideration such factors as changes in the nature and volume of specific
problem loans and current economic conditions that may affect the borrower's
ability to repay.

The balance of the reserve for loan losses was $4,877,101 at June 30, 1994
compared to $3,952,216 at June 30, 1993 and to $5,976,175 at March 31, 1994.
Net losses totaled $1,199,074 in the second quarter of 1994 compared to
$182,880 in the second quarter of 1993 and to $14,166 in the first quarter of
1994.

Loans on non-accrual totaled $1,189,529 at June 30, 1994 compared to $4,897,000
at June 30, 1993 and to $3,905,956 at March 31, 1994.  The previous increase
was due to deterioration in the local economy, particularly in real estate.  As
of June 30, 1994, the Bank owned two parcels of other real estate with a book
value totaling $3,945,373 compared to one parcel having a book value of
$608,732 at June 30, 1993.

Investment Portfolio

The Bank adopted SFAS No. 115, "Accounting for Certain Investments in Debt &
Equity Securities," as of December 31, 1993.  SFAS 115 requires entities to
classify investments in debt securities and equity securities with readily
determinable fair values as held to maturity, available for sale, or trading
and establishes accounting and reporting requirements for each classification.
The Bank has classified all of its investments as available for sale as it does
not have the intent to hold such securities until maturity.  Available for sale
securities are reported at fair value, with unrealized gains and losses, net of
taxes, reported as separate component of shareholders' equity.  At June 30,
1994, this separate component of equity was $870,920.

The portfolio increased by $27,715,487, or 39.50% to $97,874,455 book value
from June 30, 1993 to June 30, 1994.  Large deposit generation coupled with low
loan demand created excess liquidity.

Letters of Credit

At June 30, 1994, the Bank's commitments under unused letters of credit were
$4,477,000 of which 20% are reasonably expected to be exercised within the next
twelve months.  At June 30, 1993, such commitments totaled $7,238,000 and at
March 31, 1994, $4,417,800.

Interest Differential
June, 1994/June, 1993
INTEREST RATES AND NET INTEREST DIFFERENTIAL

The major portion of the Bank's income results from the difference between
interest income derived from earning assets and interest expense paid on 
liabilities incurred primarily for the funding of those assets. The difference 
is referred to as net interest income.  Net interest income expressed as a 
percent of average total earning assets is referred to as net interest margin.  
Net interest income and net interest margin are summarized in the following
comparisons for the three months ended June 30, 1994 over the same period in
1993 and for the three months ended March 31, 1994.  Average balances are
expressed in thousands of dollars:

                         NOTES TO FINANCIAL STATEMENTS

                        Quarter ended September 30, 1994


The financial statements included herein are unaudited.  The information
furnished herein reflects all adjustments which are, in the opinion of
management, necessary to a fair statement of the results of the interim period
ended September 30, 1994.

 
NOTE A - Summary of Significant Accounting Policies

Investment Securities

The Bank adopted Statement of Financial Accounting Standards No. 115,
"Accounting for Certain Investments in Debt and Equity Securities" as of
December 31, 1993.  The Bank has classified its investment securities as
available for sale.  Available for sale securities are reported at fair value,
with unrealized gains and losses, net of taxes, reported as a separate
component of shareholders' equity.  Amortization of premiums and accretion of
discounts arising at acquisition of investment securities are included in
income using methods that approximate the interest method.

Loans

Loans are stated net of undisbursed funds.  Interest on commercial, consumer
installment and real estate loans is accrued on a simple interest basis.
Interest on loans is not accrued in those instances where management considers
principal amounts doubtful of collection.

Loan Fees

Nonrefundable fees for loan origination and commitments in excess of direct
costs of originating the loan or commitment are amortized over the life of the
loan using the straight line method.  Fees originated since 1988 are recognized
as income using the interest method as required by FASB 91.

Allowance for Loan Losses

The allowance for loan losses is established through charges to earnings in the
form of a provision for loan losses.  Loans which are determined to be
uncollectible are charged against this allowance, and subsequent recoveries, if
any, are credited to the allowance.



                                      10
<PAGE>   51
The allowance for loan losses is an amount that management believes will be
adequate to absorb possible losses on existing loans that may become
uncollectible, based on evaluations of the collectability of loans and prior
loan experience.  The evaluations take into consideration such factors as
changes in the nature and volume of specific problem loans and current or
anticipated economic conditions that may affect the borrowers' ability to pay.

Premises and Equipment

Premises and equipment are stated at cost, less accumulated depreciation and
amortization.  Depreciation is computed using the straight line method over
estimated useful lives of the assets.

Income Per Share of Common Stock

Net income per share is based upon the weighted average number of common shares
outstanding adjusted by the dilutive effect of stock options outstanding on a
fully diluted basis.

NOTE B - Provision for Income Taxes

No portion of income tax provision is attributable to foreign operations.  The
provision for income tax has been calculated taking into account the tax-exempt
status of portions of municipal bond income.  Of the federal statutory income
tax rate of 34%, the following are the components of the current quarter
provision:

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

Capital

During the third quarter of 1994, the Bank's capital increased by $1,134,933,
or 3.31%, compared to an increase of $540,288, or 1.79% in the same period of
1993.  Without the effect of the adoption of SFAS 115, "Accounting for Certain
Investments in Debt and Equity Securities" as of December 31, 1993, this
increase was $870,920 or 2.61%.  Sources of additional capital in each of the
periods were retained earnings, exercise of stock options and purchases of new
stock by the Bank's profit sharing and 401K plans.  The Bank paid a dividend of
thirty-five cents a share to shareholders of record July 13, 1994, or a total
of $485,624.  A dividend of $.35 per share, totaling $468,053 was paid in the
third quarter of 1993.  Dividend payments continued on a quarterly basis in
1993 and 1994.

The Bank is subject to the Federal Reserve Bank's regulations.  In 1989, the
Federal Reserve Bank established risk-based capital guidelines for member
banks.  The Comptroller of the Currency and the FDIC have issued similar
guidelines for national banks.  The guidelines define Tier 1 Capital and Total
Capital.  Tier 1 Capital consists of common and qualifying preferred
shareholders' equity and minority interests in equity accounts of consolidated
subsidiaries.  Total Capital consists of, in addition to Tier 1 Capital,
mandatory convertible debt, preferred stock not qualifying as Tier 1 Capital,
subordinated and other qualifying term debt and a portion of the allowance for
loan losses less the remaining 50% of investments in unconsolidated
subsidiaries.  The Tier 1 component must comprise at least 50% of qualifying
Total Capital.  Risk-based capital ratios are calculated with reference to
risk-weighted assets which include both on and off-balance sheet exposures.
The minimum required qualifying total capital ratio is 8%, of which at least 4%
must consist of Tier 1 Capital.  At September 30, 1994, the Bank's Tier 1
Capital totaled $34,993,000 and Total Capital was $38,210,000.  The Bank's Tier
1 capital to total risk weighted assets ratio was 13.60% and its Total Capital
to total risk weighted assets ratio was 14.85%.

It is the intention of the Bank to continue capital augmentation through
earnings retention net of dividends in future years.

Liquidity

Historically, the Bank's balance sheet has shown a high degree of liquidity.
The following table shows balance sheet proportions for the quarter ending
September 30, 1994 and for the years ending December 31, 1993 and December 31,
1992.

Totals may not add due to rounding.

Bank assets containing a high degree of liquidity are Cash & Due From Banks,
Investment Securities and Federal Funds Sold.  For the quarter ending September
30, 1994, those assets comprised 42.24% of the Bank's assets compared to 34.83%
in 1993 and 33.80% in 1992.

A principal source of liquidity is new deposit generation.  Historically, loan
generation has periodically lagged deposit growth.  The loan to deposit ratio
decreased from 66.50% in 1992 to 65.15% in 1993 and to 57.44% in the third
quarter of 1994.  Growth rates for the third quarter of 1994 and for the years
1993 and 1992 are shown in the following table.

The investment portfolio is another source of liquidity.  While a portion of
the portfolio is intended to be a permanent investment, a portion is invested
in short-term obligations pending re-employment of these funds in the loan
portfolio or for deposit withdrawals.  As of September 30, 1994, the investment
portfolio totaled $112,416,814. Of that amount, $1,447,256, or 1.29% of the
total portfolio matures  within one year.  Additionally, the securities in the
portfolio are freely marketable.  The portfolio contains $745,049 in unrealized
appreciation.

Within the loan portfolio are investments in short-term bankers acceptances
totaling $14,672,051 at September 30, 1994.  These acceptances all mature
within 180 days.

Other internal sources of liquidity are the retention of earnings and cash flow
generated in the loan portfolio.

External sources of liquidity include borrowings available to the Bank.  As of
September 30, 1994, the Bank has two lines available totaling $10,000,000 of
which $5,000,000 is committed until June 30, 1995, and on which commitment fees
have been paid.  $5,000,000 is on an "as available" basis.

Indebtedness of Management

The Bank has had, and expects to have in the future, banking transactions in
the ordinary course of its business with directors, officers, principal
shareholders and their associates, on the same terms, including interest rates
and collateral on loans, as those prevailing at the same time for comparable
transactions with others, and which, in the opinion of the Bank's Management,
do not involve a greater risk of collectibility.  Furthermore, it is the Bank's
policy to preclude its executive officers, with the exception of the Chairman
of the Board, from borrowing from the Bank and any loan to the Chairman or a
director must be approved by the entire Board of Directors.

The following table summarizes the loans to Directors and Principal Holders of
Equity Securities in the quarter ended September 30, 1994:

Results of Operations

In the quarter ended September 30, 1994, average daily assets increased



                                      14
<PAGE>   55
by $46.6 million or 12.30% over the third quarter 1993 and increased by $13.1
million, or 3.18%, over the second quarter of 1994.  Deposits and other
borrowings increased $42.6 million, or 12.30% over the third quarter of 1993
and increased $10.5 million, or 2.76% over the first quarter of 1994.

The mix in earning assets reflects a decrease in loan demand.  Loans, net of
banker's acceptances, as a percent of earning assets were 59.63% for the
quarter ended September 30, 1994, compared to 66.26% for the third quarter of
1993 and 59.28% for the second quarter of 1994.

Net Interest Income and Margin

In the three months ended September 30, 1994, net interest income on a fully
taxable equivalent basis increased $551,000, or 11.17% from the preceding
quarter and increased $824,000, or 17.69%, over the same period in 1993.

Interest-earning assets averaged $379.2 million, an increase of $42.2 million,
or 12.53%, over the same period in 1993.  Interest earned on those assets
increased $1,188,000, or 18.95%, for a total of $7,456,000 in this period.  The
composite fully taxable equivalent yield on interest-earning assets increased
from 7.38% in the third quarter of 1993 to 7.80% in the current period.
Compared with the preceding period, interest on earning assets increased
$762,000, or 11.38%.  Yields increased fifty five basis points from 7.25% to
7.80%.

Average interest-bearing liabilities increased by $42.6 million to $389.4
million, or 12.30% over the same period in 1993.  Interest expense increased
$364,000, or 22.61%.  The composite average cost of funds increased from 1.84%
to 2.01%.  In this quarter, compared to the prior quarter, the cost of funds
increased by fourteen basis points from 1.87% to 2.01%.  Net interest margin
decreased from 5.48% in the third quarter of 1993 to 5.34% in the second
quarter of 1994 and increased to 5.74% in the current quarter.

Non-Interest Income

In this period, non-interest income increased $200,000, or 22.79% over the same
period in 1993 and increased $240,000, or 28.30% from the prior period.
Non-interest income is derived from Trust Department fees, service charges on
deposit accounts, other fees and charges and safe deposit rentals.  In this
period, trust fees accounted for $753,000 or 69.92% of non-interest revenue.
Increases in non-interest income over the prior quarter are due to increased
volume of trust business.





Non-Interest Expense

Non-interest expense increased $423,000, or 12.72%, in this period compared to
the same period in 1993, and increased $30,000 or 0.81% over the prior period.
Overall increases in non-interest expense are due to increases in deposits and
earning assets and increased

staff and other costs necessary to service this growth.

Provision for Loan and Lease Losses

The Bank provided $75,000 for loan losses in this period compared to $500,000
in the third quarter of 1993 and to $100,000 in the second quarter of 1994.
The Bank's Reserve for Loan Losses is maintained at a level that Management
believes will be adequate to absorb possible losses. During the preceeding
quarter, the Bank adopted a new loan loss adequacy policy to conform to the new
federal guidelines "Interagency Policy Statement on the Allowance for Loan and
Lease Losses (ALLL)" which was issued December 21, 1993.  Management
evaluations take into consideration such factors as changes in the nature and
volume of specific problem loans and current economic conditions that may
affect the borrower's ability to repay.

The balance of the reserve for loan losses was $4,738,343 at September 30, 1994
compared to $4,044,239 at September 30, 1993 and to $4,877,101 at June 30,
1994.  Net losses totaled $213,757 in the third quarter of 1994 compared to
$407,977 in the third quarter of 1993 and to $1,199,074 in the second quarter
of 1994.

Loans on non-accrual totaled $1,371,058 at September 30, 1994 compared to
$4,817,855 at September 30, 1993 and to $1,189,529 at June 30, 1994.  The
previous increase was due to deterioration in the local economy, particularly
in real estate.  As of September 30, 1994, the Bank owned two parcels of other
real estate with a book value totaling $3,945,373 compared to one parcel having
a book value of $608,732 at September 30, 1993.

Investment Portfolio

The Bank adopted SFAS No. 115, "Accounting for Certain Investments in Debt &
Equity Securities," as of December 31, 1993.  SFAS 115 requires entities to
classify investments in debt securities and equity securities with readily
determinable fair values as held to maturity, available for sale, or trading
and establishes accounting and reporting requirements for each classification.
The Bank has classified all of its investments as available for sale as it does
not have the intent to hold such securities until maturity.  Available for sale
securities are reported at fair value, with unrealized gains and losses, net of
taxes, reported as separate component of shareholders' equity.  At September
30, 1994, this separate component of equity was $439,579.

The portfolio increased by $43,256,989, or 62.55% to $112,416,814 book value
from September 30, 1993 to September 30, 1994.  Large deposit generation
coupled with low loan demand created excess liquidity.


Letters of Credit

At September 30, 1994, the Bank's commitments under unused letters of credit
were $4,045,000 of which 20% are reasonably expected to be exercised within the
next twelve months.  At September 30, 1993, such commitments totaled $6,985,222
and at June 30, 1994, $4,477,000.

Interest Differential
September, 1994/September, 1993
INTEREST RATES AND NET INTEREST DIFFERENTIAL

The major portion of the Bank's income results from the difference between
interest income derived from earning assets and interest expense paid on
liabilities incurred primarily for the funding of those assets.  The
difference is referred to as net interest income.  Net interest income
expressed as a percent of average total earning assets is referred to as
net interest margin.  Net interest income and net interest margin are
summarized in the following comparisons for the three months ended
September 30, 1994 over the same period in 1993 and for the three months
ended June 30, 1994.  Average balances are expressed in thousands of
dollars:

PART I.

ITEM 1.     BUSINESS

General

The Bank commenced operations on May 13, 1980.  Its principal banking office is
located at 250 Lytton Avenue, Palo Alto, California.  Since its formation, the
Bank has provided basic banking services and personal trust services to
individuals and business enterprises in the Palo Alto area.  Palo Alto is
located on the San Francisco Peninsula, approximately 30 miles south of San
Francisco, on the northern periphery of "Silicon Valley".

The Bank's primary service area is considered to be the communities of Palo
Alto, Menlo Park, Atherton and Portola Valley plus the unincorporated areas of
Ladera and Stanford University.  This primary service area is oriented towards
professional services, light industry, retail businesses and education.

The Bank considers its principal service a "banking relationship", the keystone
of which is a transaction account.  In the case of corporations, the
transaction account is a demand (checking) account.  In the case of
individuals, it is a Super-NOW account that pays interest, provided that
sufficient funds (i.e., either a daily minimum balance of $3,000, or an average
monthly balance of $6,000) are maintained.  Once a customer has established the
"relationship" with the Bank by opening a transaction account, that customer
may utilize all other Bank services, including money fund accounts,
certificates of deposit, safe deposit box rentals, cashier's checks, and the
purchase of U.S. postage stamps, U.S. Savings Bonds and traveler's checks.  The
bank also makes available to qualified customers commercial, personal and real
estate loans, credit cards and standby letters of credit.  Through its
correspondents, the Bank is also able to offer limited international banking
and municipal bond trading services.

The Bank's Trust Department specializes in personal trust services and acts as
trustee on a range of employee benefit plans.  The Bank does not provide stock
transfer services.  The Bank maintains a Trust Representative Office at 133
Mission Street, Santa Cruz, CA.

The Bank has an office at 800 Oak Grove, Menlo Park, CA.  The Bank has
automatic teller machines at its two offices and it issues an ATM card which
enables a customer to withdraw cash at over 25,000 offices of other financial
institutions world wide which are members of  Cirrus, Money Network, Star
System, American Express and the Interlink Network.  The Bank also maintains an
ATM machine at the Forum, 23500 Christo Rey Drive, Cupertino, CA.  The Bank
employed 119 full time and 6 part-time staff at year end.







                                      1

Competition From Other Financial Institutions

The Bank considers its principal market area to be composed of the communities
of Palo Alto, Menlo Park, Atherton, Portola Valley and Stanford.  According to
the 1990 Census, the aggregate population of these communities was 118,390.
The 1990 Census further indicates that individuals 18 years old or older with
four or more years of college education totalled 55.8% of this market, versus
28.2% for the San Francisco Bay Area and 20.8% for the State of California.
Individuals in this primary market area who were 16 years old or older at the
1990 Census date and who were employed as  executives, administrators, managers
or in a professional specialty totalled 52.7%, as compared to 33.1% for the San
Francisco Bay Area and 28.6% for the State of California.

This market is very heavily serviced by financial institutions.  There are 35
commercial banking offices, 14 savings and loan offices, 19 securities
brokerage firms and 5 credit unions within this market area.  The 35 banking
offices alone had deposits from individuals, partnerships and corporations
totalling $2.8 billion as of June 30, 1992, compared to $1.6 billion at
December 31, 1983.  The Bank's market share was 2.17% on December 31, 1982,
3.88% on December 31, 1983, 4.49% on December 31, 1984, 6.39% on December 31,
1985, 6.50% on December 31, 1986, 8.57% on December 31, 1987, 9.59% on December
31, 1988, 9.74% on December 31, 1989, 10.07% on December 31, 1990, 10.52% on
December 31, 1991 and 11.03% on June 30, 1992.

With regard to loans, the Bank competes with other commercial banks, savings
and loan associations, consumer finance companies and other lending
institutions.  The Bank's Trust Department competes with the trust departments
of all the major banks operating within the Bank's primary service area.

In addition to its principal market area, the Bank considers as a secondary
market area, the surrounding communities of Woodside, Los Altos, Mountain View,
Sunnyvale, and Santa Clara to the south and Redwood City, San Carlos, Belmont
and San Mateo to the north.  The Bank services customers in these areas by mail
or by the use of its six courier vans, which pick up non-cash deposits on
scheduled routes.

Outside its primary market area, the Bank competes with other national banks,
state banks, savings and loan associations, and credit unions for time and
savings deposits, other deposits, checking or draft accounts, and loans
throughout the San Francisco Bay area.  With respect to certain of its
services, including, but not limited to, loans, and particularly with respect
to securing funds available for deposits, the Bank competes with other
financial institutions such as insurance companies, consumer and business
finance or loan companies, industrial loan associations, real estate investment
trusts, 





                                      2



<PAGE>   6
pension funds, mortgage companies, and credit card organizations.  The
national equity and debt securities markets also compete for available funds.

Many of the Bank's competitors offer a comprehensive array of banking products
which the Bank has chosen not to offer, and these competitors thereby may have
a competitive advantage over the Bank.  Further, many of the Bank's competitors
have long established reputations and loyal customer bases.  However,
management of the Bank believes that the level of service which it provides in
the delivery of banking services to its customers contributes to the Bank's
ability to obtain market share in the face of such competition.

Many of the banks and other financial institutions, including regional money
center banks, with which the Bank competes, have capital and resources
substantially in excess of the capital and resources of the Bank.  Because
banks, including the Bank, are generally restricted from lending in excess of a
specified percentage of their capital base to one borrower, the Bank is
dependent upon its correspondent relationships for loan participations in order
to accommodate loan requests in excess of its legal lending limit.  The Bank's
legal limit on unsecured lending to any one entity was $4,539,852 on December
31, 1992.

To a certain extent, the Bank is also faced with competition from banks and
other institutions located in money centers outside of California, and from
foreign banks which maintain representative offices in California.

Commitments

As of December 31, 1992, and December 1991, the Bank's loan commitment by
category is as follows:

</TABLE>

All commitments made are "firm" and could be drawn.  The largest category of
commitments is Commercial Loans ($40,269M [50.05%]).  The Bank expects
approximately 50% of these commitments to be drawn.  The Bank anticipates that
50% of the commitments in the next largest category, Consumer Revolving Loans
($29,305M [36.42%]) to be drawn.  Less than 5% of the commitments are fixed
rate commitments.

Commercial loan commitments are generally in the form of revolving lines of
credit with floating interest rates and typically mature within one year.  All
other commitments are on terms whereby prices of interest rates are to be
determined by market conditions prevailing at the time of exercise.

Concentration of Bank Deposits

There are no material portions of the Bank's deposit base obtained from a
single person or group of persons.  The Bank has no deposits of Federal, State
or Local governments other than a Treasury Tax and Loan account.  At December
31, 1992, the Bank had deposits totaling $48,167,122 from its Trust Department.
That total represents deposits of 705 individual trust accounts.

As of December 31, 1992, the Bank's deposit structure was as follows:

Foreign Sources of Business

There are no material deposit liabilities incurred from outside the Bank's
primary and secondary service areas.  The Bank has no brokered deposits and has
a policy not to accept any.  The Bank's loans are made primarily to
professionals, executives and privately held companies in the Bank's market
area.  From time to time, loan participations are purchased  from another bank.
As of December 31, 1992, participations totaling $536,392 were included in the
Bank's portfolio.

SUPERVISION AND REGULATION


The Bank is regulated and supervised by the Comptroller and, therefore, is
subject to periodic examination by the Comptroller.  Deposits of the Bank's
customers are insured by the FDIC up to the maximum limit of $100,000.  As a
national bank, the Bank is a member of the Federal Reserve System and is
subject to the regulations of the Federal Reserve Board.

The regulations of those federal bank regulatory agencies govern most aspects
of the Bank's business and operations, including but not limited to requiring
the maintenance of non-interest bearing reserves on deposits, limiting the
nature and amount of investments and loans which may be made, regulating the
issuance of securities, restricting the payment of dividends, regulating bank
expansion and bank activities and determining maximum rates of interest allowed
on certain deposits.

Effect of State Law

The laws of the State of California also affect the Bank's business and
operations.  For example, under 12 U.S.C. Section 36, the Comptroller may
authorize a national bank to establish branch offices only to the extent
allowable under state law for state banks.  Therefore, as California law
presently permits a state bank to establish a branch office at any location in
the state, a national bank may be similarly authorized to establish a branch by
the Comptroller.  On a similar basis, 12 U.S.C. Section 85 provides that state
law, in most circumstances, determines the maximum rate of interest which a
national bank may charge on a loan.  As California law exempts all
state-chartered and national banks from the application of its usury laws,
national banks are also provided such an exemption pursuant to Section 85.

Capital Adequacy Requirements

The Bank is subject to regulations of the Comptroller governing capital
adequacy, which incorporate both risk-based and leverage capital requirements.
As noted below, the federal bank regulatory agencies have recently solicited
comment in anticipation of a proposed regulation which would impose additional
capital requirements on banks based on the interest rate risk inherent in the
bank's portfolio.

         Risk-Based Capital Guidelines
                                     
The Comptroller's regulations for national banks set total capital requirements
and define capital in terms of "core capital elements" (comprising Tier 1
capital) and "supplemental capital elements" (comprising Tier 2 capital).  Tier
1 capital is generally defined as the sum of the core capital elements less
goodwill.  The following items are defined as core capital elements: (i) common
stockholders' equity; (ii) qualifying noncumulative perpetual preferred stock;
and (iii) minority interests in the equity

                                      6

accounts of consolidated subsidiaries.  Supplementary capital elements include:
(i) allowance for loan and lease losses (which cannot exceed 1.25% of an
institution's risk weighted assets); (ii) perpetual preferred stock not
qualifying as core capital; (iii) hybrid capital instruments and mandatory
convertible debt instruments; and (iv) term subordinated debt and
intermediate-term preferred stock.  The maximum amount of supplemental capital
elements which qualifies as Tier 2 capital is limited to one-hundred percent
(100%) of Tier 1 capital, net of goodwill.

Risk-based capital ratios are calculated with reference to risk-weighted
assets, including both on and off-balance sheet exposures, which are multiplied
by certain risk weights assigned by the Federal Reserve Board to those assets.
Both bank holding companies and national banks are required to maintain a
minimum ratio of qualifying total capital to risk-weighted assets of eight
percent (8%), at least one-half of which must be in the form of Tier 1 capital.

There are presently four risk-weight categories (0%, 20%, 50% and 100%).  The
risk-weight categories are substantially as follows: (A) cash, all direct
claims (including securities, loans and leases) on or directly and
unconditionally guaranteed by the U.S.  government or agencies thereof and the
central governments of OECD countries(1), and securities issued by or
unconditionally backed by the U.S. government or its agencies which are
actively traded in financial markets carry a 0% risk weight; (B) cash items in
the process of collection, short-term claims on or guaranteed by U.S.
depository institutions and foreign banks, long-term claims on or guaranteed by
U.S. depository institutions and OECD banks, and claims collateralized by cash
on deposit at the bank or by securities issued or guaranteed by the U.S.
government, OECD central governments or other agencies carry a 20% risk weight;
(C) qualifying mortgage loans, qualifying mortgage-related securities, and
revenue (non-general obligation) bonds or similar obligations of the states or
other political subdivisions of the U.S. or OECD countries carry a 50% risk
weight; and (D) all assets not specified above or otherwise deducted from
calculations of capital including, but not limited to, consumer loans,
commercial loans, home equity loans, non-qualifying mortgage related
securities, investment in fixed assets and premises, other real estate owned,
and industrial development bonds and other similar obligations carry a 100%
risk weight.  The bulk of the assets typically found in a commercial bank loan
portfolio would be assigned to the 100% category.

The federal banking agencies have issued a joint advance notice of proposed
rulemaking to solicit comments on a framework for revising their risk-based
capital guidelines to take account of interest rate risk.  As required by the
Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA"), the
notice seeks comment on a proposed method of incorporating an interest rate

component into the current risk-based capital guidelines, with the goal of
ensuring that institutions with high levels of interest rate risk have
sufficient capital to cover their exposures.  Interest rate risk is the risk
that changes in market interest rates might adversely affect a bank's financial
condition.  As financial intermediaries, depository institutions accept
interest rate risk as a normal part of their business.  They assume this risk
whenever the interest rate sensitivity of their assets does not match the
sensitivity of their liabilities or off balance sheet positions.  Thus, when
interest-sensitive assets and liabilities reprice at mismatched intervals, an
increase or decrease in interest rates will affect net interest income.  Under
the proposal, interest rate risk exposures would be quantified by weighing
assets, liabilities and off-balance sheet items by risk factors which
approximate sensitivity to interest rate fluctuations.  Institutions identified
as having an interest rate risk exposure greater than a defined threshold would
be required to allocate additional capital to support this higher risk.  The
capital to be allocated would be a dollar amount equal to the percentage by
which the risk exceeds the defined threshold multiplied by the institution's
total assets.  Higher individual capital allocations could be required by the
bank regulators based on supervisory concerns.

As noted above, the federal banking agencies have solicited comments on this
proposal but have not yet proposed regulations to implement any interest rate
risk component into the risk-based capital guidelines.  Accordingly, the
ultimate impact on the Bank of a final regulation in this area cannot be
predicted at this time.

         Leverage Capital Guidelines

The Comptroller has established a minimum leverage ratio of three percent (3%)
Tier 1 capital to total assets for national banks that have received the
highest composite regulatory rating and are not anticipating or experiencing
any significant growth.  All other institutions will be required to maintain a
leverage ratio of at least 100 to 200 basis points above the three percent (3%)
minimum.

Set forth below are Bank's risk based and leverage capital ratios as of
December 31, 1992:

Management of the Bank believes that the Bank will continue to meet their
respective minimum capital requirements in the foreseeable future.

Payment of Dividends

The ability of the Bank to make dividend payments is subject to statutory and
regulatory restrictions.  The Bank paid cash dividends in the amount of
$1,430,163 in the fiscal year ended December 31, 1992.

                                       9
<PAGE>   13

The Board of Directors of a national bank may declare the payment of dividends
depending upon the earnings, financial condition and cash needs of the bank and
general business conditions.  A national bank may not pay dividends from its
capital.  All dividends must be paid out of net profits then on hand, after
deducting losses and bad debts.  A national bank is further prohibited from
declaring a dividend on its shares of common stock until its surplus fund
equals the amount of capital stock or until 10% of the bank's net profits of
the preceding half year in the case of quarterly or semiannual dividends, or
the preceding two consecutive half-year periods in the case of an annual
dividend, are transferred to the surplus fund.  Moreover, the approval of the
Comptroller is required for the payment of dividends if the total of all
dividends declared by the bank in any calendar year would exceed the total of
its net profits of that year combined with its retained net profits of the two
preceding years, less any required transfers to surplus or a fund for the
retirement of any preferred stock.

In addition to the above requirements, guidelines adopted by the Comptroller
set forth factors which are to be considered by a national bank in determining
the payment of dividends.  A national bank, in assessing the payment of
dividends, is to evaluate the bank's capital position, its maintenance of an
adequate allowance for loan and lease losses, and the need to revise or develop
a comprehensive capital plan.

Moreover, the Comptroller has broad authority to prohibit a national bank from
engaging in banking practices which it considers to be unsafe or unsound.  It
is possible, depending upon the financial condition of the national bank in
question and other factors, that the Comptroller may assert that the payment of
dividends or other payments by a bank is considered an unsafe or unsound
banking practice and therefore, implement corrective action to address such a
practice.

Accordingly, the future payment of cash dividends by the Bank will not only
depend upon the Bank's earnings during any fiscal period but will also depend
upon the assessment of its Board of Directors of capital requirements and other
factors, including dividend guidelines and the maintenance of an adequate
allowance for loan and lease losses.

Impact of Monetary Policies

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


                                       10
<PAGE>   14

The earnings and growth of the Bank are affected not only by general economic
conditions but also by the monetary and fiscal policies of the United States
and federal agencies, particularly the Federal Reserve Board.  The Federal
Reserve Board can and does implement national monetary policy, such as seeking
to curb inflation and combat recession, by its open market operations in United
States Government securities and by its control of the discount rates
applicable to borrowings by banks from the Federal Reserve System.  The actions
of the Federal Reserve Board in these areas influence the growth of bank loans,
investments and deposits and affect the interest rates charged on loans and
paid on deposits.  The nature and timing of any future changes in monetary
policies are not predictable.

Extensions of Credit to Insiders and Transactions with Affiliates.

Sections 22(h) of the Federal Reserve Act and Regulation O promulgated
thereunder place limitations and conditions on loans or extensions of credit
to: a bank's or bank holding company's executive officers, directors and
principal shareholders (i.e., in most cases those persons who own, control or
have power to vote more than ten percent (10%) of any class of voting
securities); any company controlled by any such executive officer, director or
shareholder (i.e., where the person directly or indirectly or acting through or
in concert with one or more other person owns, controls or has the power to
vote twenty-five percent (25%) or more of any class of voting securities,
controls the election of a majority of directors, or has the power to exercise
a controlling influence over management or policies); or any political or
campaign committee controlled by such executive officer, director or principal
shareholder.

Loans extended to any of the above persons must comply with loan-to-one-
borrower limits, require prior full board approval when aggregate extensions of 
credit to such person exceed specified amounts, must be made on substantially 
the same terms (including interest rates and collateral) as, and following 
credit-underwriting procedures that are not less stringent than, those 
prevailing at the time for comparable transactions with non-insiders, and must 
not involve more than the normal risk of repayment or present other unfavorable 
features.  Regulation O also prohibits a bank from paying an overdraft on an 
account of an executive officer or director, except pursuant to a written 
pre-authorized interest-bearing extension of credit plan that specifies a 
method of repayment or a written pre-authorized transfer of funds from another 
account of the officer or director at the bank.

The provisions of Regulation O summarized above reflect substantial
strengthening as a result of the adoption of FDICIA.  FDICIA also resulted in
an amendment to Regulation O which provides that the aggregate limit on
extensions of credit to all insiders of a bank as a group cannot exceed the
bank's unimpaired capital and unimpaired surplus.  An exception to this
limitation is provided, until May 18, 1993, for banks with less than
$100,000,000 in deposits.  The aggregate limit applicable to such  banks is two
times the bank's unimpaired capital and unimpaired surplus,


                                       11
<PAGE>   15
provided the bank meets or exceeds all applicable capital requirements.

Sections 23A and 23B of the Federal Reserve Act impose restrictions on
transactions between a member bank and its affiliates, including its holding
company and certain other companies, with respect to extensions of credit,
purchases of investment securities or assets of an affiliate, acceptance of
securities issued by an affiliate as collateral or the issuance of a guarantee,
acceptance or letter of credit on behalf of an affiliate.  Such transactions
may not exceed 10% of the capital stock and surplus of the bank on a per
affiliate basis and the aggregate of all such transactions may not exceed
twenty percent (20%) of the capital and surplus of the bank.  Similarly, each
of the foregoing transactions, as well as the sale of securities or other
assets to an affiliate, the payment of money or furnishing of services to an
affiliate, and the payment of a fee to an affiliate for acting as a broker or
dealer, may not be entered into by a bank except on terms and under
circumstances, including credit standards, that are substantially the same or
at least as favorable to the bank as those prevailing at the time for
transactions with non-affiliated companies.

Recent and Proposed Legislation

Federal and state laws applicable to financial institutions have undergone
significant changes in recent years.  The most significant recent federal
legislation enactments are the Federal Deposit Insurance Corporation
Improvement Act of 1991 and the Financial Institutions Reform, Recovery, and
Enforcement Act of 1989.

         Federal Deposit Insurance Corporation Improvement Act of 1991

         General
               
FDICIA was enacted on December 19, 1991 and addresses, among other things, the
safety and soundness of the deposit insurance funds, supervision of and
accounting by insured depository institutions and prompt regulatory action by
the federal bank regulatory agencies with respect to troubled institutions.
FDICIA gives the FDIC, in its capacity as federal insurer of deposits, broad
authority to promulgate regulations to assure the viability of the deposit
insurance funds.  FDICIA also places restrictions on the activities of
state-chartered institutions and on institutions failing to meet minimum
capital standards and provides enhanced enforcement authority for the federal
banking agencies.  As noted above, FDICIA also strengthened Federal Reserve Act
regulations regarding insider transactions.

FDICIA requires the FDIC and the other banking regulatory agencies to
promulgate regulations within time frames specified in individual sections of
the Act.  Where relevant to the Bank's operations, such recently promulgated or
proposed regulations are described herein.  However, because the effect of
proposed regulations on the Bank's operations will remain unknown until their
final adoption, and since it is possible that final


                                       12
<PAGE>   16
regulations will differ substantially from the regulations in proposed form, no
prediction or assurance can be given as to the actual or potential impact of
such future final regulations on the Bank.

         Prompt Corrective Action                                

FDICIA amended the Federal Deposit Insurance Act ("FDIA") to establish a format
for closer monitoring of insured depository institutions and to enable prompt
corrective action by regulators when an institution begins to experience
difficulty.  The general thrust of these provisions is to impose greater
scrutiny and more restrictions on institutions as they descend the
capitalization ladder.

FDICIA establishes five capital categories for insured depository institutions:
(a) well capitalized; (b) adequately capitalized; (c) undercapitalized; (d)
significantly undercapitalized; and (e) critically undercapitalized.  Relevant
capital measures for determining the placement of a depository institution
within a category include a leverage limit, a risk-based capital requirement
and other capital measures which may be established from time to time by
regulations adopted by the federal banking agencies.  Regulations recently
adopted jointly by the federal banking agencies define the relevant capital
measures for the four highest capital categories to be the ratio of total
capital to risk-weighted assets, the ratio of Tier 1 capital to risk-weighted
assets and the ratio of Tier 1 capital to total average assets (the leverage
ratio).  The ratio of tangible equity to total assets was adopted as the sole
relevant capital measure for defining the critically undercapitalized category.
Under the regulations, an institution will be deemed to be:

"Well capitalized" if it has a total risk-based ratio of ten percent (10%) or
more, a Tier 1 risk-based ratio of six percent (6%) or more and a leverage
ratio of five percent (5%) or more, so long as the institution is not subject
to an order, written agreement, capital directive or prompt corrective action
directive to meet and maintain a specific capital level for any capital
measure;

"Adequately capitalized" if it has a total risk-based ratio of eight percent
(8%) or more, a Tier 1 risk-based ratio of four percent (4%) or more and a
leverage ratio of four percent (4%) or more and does not meet the definition of
a well-capitalized institution(1);

"Undercapitalized" if it has a total risk-based ratio of less than eight
percent (8%), a Tier 1 risk-based ratio of less than four percent (4%) or a
leverage ratio of less than four percent (4%)(1);




- ------------
(1)  A leverage ratio of three percent (3%) or more is permitted if the 
     institution has received the highest composite rating in its most recent 
     report of examination and is not anticipating or experiencing significant
     growth.



                                      13
<PAGE>   17
"Significantly undercapitalized" if it has a total risk-based ratio of less
than six percent (6%), a Tier 1 risk-based ratio of less than three percent
(3%) or a leverage ratio of less than three percent (3%); and

"Critically undercapitalized" if it has a ratio of tangible equity to total
assets that is equal to or less than two percent (2%).

The regulations require each institution to notify its primary regulator within
15 days following the occurrence of any material event that would cause the
institution to fall into a lower capital category than the category previously
assigned to the institution.

All institutions are barred from making capital distributions or paying
management fees to a controlling person if to do so would cause the institution
to fall into any of the three undercapitalized categories.

Undercapitalized institutions will be subject to the following mandatory
supervisory actions:

- -  Increased monitoring by the appropriate federal banking agency and periodic 
   review of the institution's efforts to restore its capital;

- -  A requirement that the institution submit to the appropriate federal banking 
   agency, generally within 45 days of becoming undercapitalized, a capital 
   restoration plan, which must include (a) the steps the institution will take 
   to become adequately capitalized; (b) the levels of capital to be attained 
   during each year in which the plan will be in effect; (c) how the 
   institution will comply with restrictions or requirements imposed on its 
   activities; and (d) the types and levels of activities in which the 
   institution will engage;

- -  A restriction on growth of the institution's total assets; and

- -  A limitation on the institution's ability to make any acquisition, open any 
   new branch offices or engage in any new line of business without the prior 
   approval of the appropriate federal banking agency or the FDIC.

Significantly undercapitalized institutions and undercapitalized institutions
that fail to submit and implement adequate capital restoration plans are
subject to the four mandatory provisions applicable to undercapitalized
institutions and, in addition, will be subject to one or more of the following
restrictions or conditions:

- -  sell enough additional capital, including voting shares, to bring the
institution to an adequately capitalized level;

- -  restrict transactions with affiliates;

                                      14
<PAGE>   18
- -  restrict interest rates paid on deposits to the prevailing rates in the
   region where the institution is located;

- -  restrict asset growth or reduce total assets;

- -  terminate, reduce or alter any activity (including any activity conducted 
   by a subsidiary of the institution) determined by the bank regulatory 
   agency to pose an excessive risk to the institution;

- -  hold a new election for the institution's board of directors;

- -  dismiss directors or senior officers and employ new officers, subject to
   agency approval;

- -  cease accepting deposits from correspondent depository institutions;

- -  divest or liquidate any subsidiary that is in danger of becoming insolvent
   and poses a significant risk to the institution or that is likely to cause
   significant dissipation of the institution's assets or earnings; or

- -  require any company that controls the institution to divest itself of any 
   affiliate of the institution (other than another insured depository 
   institution) if the federal banking agency for the holding company 
   determines that the affiliate is in danger of becoming insolvent and poses 
   a significant risk to the institution or is likely to cause significant 
   dissipation of the institution's assets or earnings.

In addition, significantly undercapitalized institutions will be prohibited
from paying any bonus or raise to a senior executive officer without prior
agency approval.  No such approval will be granted to an institution which is
required to but has failed to submit an acceptable capital restoration plan.

A critically undercapitalized institution will face even more severe
restrictions.  In addition to those steps that can be taken with respect to
significantly undercapitalized institutions, a critically undercapitalized
institution must be placed in conservatorship or receivership within ninety
(90) days of becoming critically undercapitalized, unless the appropriate
federal banking agency determines, with FDIC concurrence, that other action
would better achieve the purposes of the FDIA.  In addition, critically
undercapitalized institutions are prohibited from taking a number of actions,
including making payments on subordinated debt, financing a highly leveraged
transaction, adopting charter or by-law amendments, materially changing
accounting methods, or paying excessive compensation or bonuses, without
obtaining prior written regulatory approval.

In addition, any company which controls a depository institution required to
submit a capital restoration plan must guarantee that the institution will
comply with the plan, provided that the liability under such guarantee will not
exceed the lesser of (i) an

                                      15
<PAGE>   19
amount equal to five percent (5%) of the institution's total assets at the time
the institution became undercapitalized; or (ii) the amount needed to bring the
depository institution into compliance with all applicable capital standards.

FDICIA also provides that if an institution is in an unsafe or unsound
condition or is engaging in an unsafe or unsound practice, its capital category
may be downgraded to achieve a higher level of regulatory scrutiny.  This is
true for institutions falling initially into any one of the capital categories
except "significantly undercapitalized."

         Annual Examinations and Reports
                                       

Effective December 19, 1992, annual full-scope, on-site regulatory examinations
will be required of all insured depository institutions, subject to exceptions
for institutions which a state banking agency has examined in the preceding
year and for small, well-capitalized institutions that are well managed and in
outstanding condition, and whose ownership has not changed in the preceding
year.  The appropriate federal banking agency will conduct the examinations,
unless the FDIC has conducted one in the given 12-month period.  However, until
December 31, 1993, exams by the federal banking agencies will generally be
conducted at 18-month intervals, unless the institution is in less than
satisfactory condition or there is new ownership.

         Brokered Deposits

FDICIA restricts the acceptance of brokered deposits by insured depository
institutions that are not well capitalized.  It also places restrictions on the
interest rate payable on brokered deposits and the solicitation of such
deposits.  An undercapitalized institution will not be allowed to solicit
brokered deposits by offering rates of interest that are significantly higher
than the prevailing rates of interest on insured deposits in the particular
institution's normal market areas or in the market area in which such deposits
would otherwise be accepted.

The FDIC has promulgated final regulations with respect to the ability of
insured depository institutions in each of the new capitalization categories to
accept brokered deposits.  Under the regulations, undercapitalized institutions
are prohibited from accepting funds obtained directly or indirectly though a
deposit broker.  Adequately capitalized institutions may accept brokered
deposits only if a waiver is first obtained from the FDIC.  Well capitalized
institutions are permitted by the regulations to accept brokered funds without
restriction.  For purposes of the brokered deposit regulation the FDIC has
stated that the term "well capitalized" means an institution whose leverage and
risk-based capital ratios are at least one to two percentage points higher than
those currently required by applicable regulations, and which has not been
notified that it is in a troubled condition.


                                      16
<PAGE>   20
In addition to the above restrictions on acceptance of brokered deposits,
FDICIA provides that no pass-through deposit insurance will be provided to
employee benefit plan deposits accepted by an institution which is ineligible
to accept brokered deposits under applicable law and regulations.

         Risk-Based Assessment System                                    

FDICIA amended the FDIA to require the FDIC to establish a risk-based
assessment system for depository institutions.  This risk- based system will be
used to calculate a depository institution's semiannual deposit insurance
assessment based on the probability that the deposit insurance fund will incur
a loss with respect to the institution.  In determining the probability of
loss, the following risks will be taken into consideration: different
categories and concentrations of assets and liabilities (both insured and
uninsured, contingent and noncontingent); and any other factors that the FDIC
determines are relevant to assessing such probability.

The FDIC has promulgated regulations to govern the transition by January 1,
1994 to a final risk-based assessment system.  The FDIC has indicated that the
risk-based assessment system should aid in reducing the cross-subsidization of
insurance funds which existed with a flat-rate system.  The transition period
began on January 1, 1993 and will last until implementation of the finalized
system on January 1, 1994.

Under the FDIC rule, the risk which each insured depository institution poses
to its insurance fund is determined on the basis of supervisory evaluations and
capitalization.  With respect to capital, insured institutions are divided into
three main capital groups:  well-capitalized (those institutions considered
"well-capitalized" for prompt corrective action purposes); adequately
capitalized  (those institutions considered "adequately capitalized" for prompt
corrective action purposes); and undercapitalized (all other institutions).
Each of the three capital categories are further subdivided by three
supervisory subgroups designated "A" (healthy), "B" (supervisory concern) and
"C" (substantial supervisory concern), resulting in a total of nine categories
for risk assessment purposes.  Under the FDIC rule proposal, the nine-category
rate schedule is expressed in terms of basis points, resulting in an assessment
range from .23% for well-capitalized institutions in subgroup "A" to .31% per
annum for undercapitalized institutions in subgroup "C."

         Certified Assessment Statements
                                       
Generally, each insured depository institution will file with the FDIC a
certified statement containing information as required by the FDIC for
determining the institution's semiannual assessment.  The form of the
certification will also contain supporting information as required by the FDIC
and is to be certified by the president of the depository institution or any
other designated officer.

                                      17

<PAGE>   21
FDICIA establishes a three-tier penalty system for failure to make accurate
certified statements.  Any insured depository institution which maintains
procedures reasonably adapted to avoid any inadvertent error and,
unintentionally as a result of such an error, fails to submit a certified
statement or submits a false or misleading certified statement or inadvertently
transmits a report that is minimally late will be subject to a penalty of not
more than $2,000 for each day a violation continues or the false or misleading
information is not corrected.  The burden of proving that an error was
inadvertent or that a report was inadvertently submitted late will be on the
institution.

A second tier penalty will be assessed against any insured depository
institution which fails to submit a certified statement within the required
time period or submits a false or misleading certified statement, without the
mitigating circumstances described above.  The penalty for a second tier
offense will be up to $20,000 for each day a violation continues or the false
or misleading information is not corrected.

Finally, if any insured depository institution knowingly or with reckless
disregard for the accuracy of any information contained in a certified
statement submits any false or misleading certified statement, the FDIC may
assess a penalty of as much as $1,000,000 or one percent (1%) of total assets,
whichever is less, per day for each day during which such failure continues or
the false and misleading information is not corrected.

         Conservatorship and Receivership

FDICIA adds grounds to the previously existing list of reasons for appointing a
conservator or receiver for an insured depository institution.  The added
grounds include:  (a) substantial dissipation of assets or earnings due to an
unsafe or unsound practice or any violation of law or regulation; (b) the
existence of an unsafe or unsound condition; (c) any willful violation of a
cease and desist order; (d) any concealment of assets, records, books or papers
from any federal or state bank regulatory agency; (e) if the institution is
likely to be unable to meet obligations in the normal course of business; (f)
losses threatening capital; (g) becoming undercapitalized if the institution
(i) has no reasonable prospect of becoming adequately capitalized, (ii) fails
to become adequately capitalized after being ordered to do so, (iii) fails to
timely submit an acceptable capital restoration plan, or (iv) fails to
implement an accepted restoration plan; or (h) is critically undercapitalized
or otherwise has substantially insufficient capital.

         Federal Reserve Discount Window Advances
                                               
Beginning December 19, 1993 no advances from a Federal Reserve Bank to any
undercapitalized depository institution may be outstanding for more than sixty
(60) days in any given 120-day period, unless the head of the appropriate
federal banking agency certifies to the Federal Reserve Bank that the
institution is viable, or if the Federal Reserve Board Chairman so certifies to
the Federal Reserve

                                      18
<PAGE>   22
Bank.  In either case, a grace period for the next sixty (60) days may be
provided.  This grace period may be extended upon further certifications.

There are more stringent restrictions on advances to critically
undercapitalized institutions.  The window is reduced to five (5) days and if
the FDIC incurs any losses exceeding what it would have lost in liquidation,
then the Federal Reserve Board is liable to the FDIC for that loss, subject to
certain limitations.  More importantly, Federal Reserve Banks shall have no
obligation to make, increase, renew, or extend any advance or discount to any
depository institution.  The Federal Reserve Board is given the prerogative of
examining any depository institution or affiliate in connection with any
Federal Reserve System transaction.

         Interbank Liabilities

On November 18, 1992 the Federal Reserve Board adopted Regulation F, Interbank
Liabilities, under Section 308 of FDICIA.  Regulation F is designed to limit
the exposure of insured depository institutions to their correspondent
institutions and thereby limit the resulting risk to the deposit insurance
funds.  Regulation F requires banks to have written policies and procedures
that take into account credit and liquidity risks, including operational risks,
in selecting correspondents and terminating those relationships.  Regulation F
limits interbank exposures related to both interday and intraday transactions
by requiring banks to: (1) establish prudential standards for exposures to each
correspondent; and (2) limit exposures to less-than-adequately capitalized
institutions to 25% of the bank's qualifying capital.

All insured banks must establish and maintain written policies and procedures
for evaluating and controlling exposures to each correspondent based on the
financial condition of the correspondent.  These policies and procedures should
be reviewed and approved annually by the bank's Board of Directors.  A bank's
review of the correspondent's financial condition can rely on publicly
available information, such as Call Reports or financial statements.  Other
parties, such as rating agencies or bankers' banks may assess the
correspondents's financial condition.  Third-party assessments must be reviewed
and approved by the bank's Board of Directors.  The regulation also requires
banks to develop and implement internal procedures to evaluate and control
intraday exposure but do not require that specific limits be placed on intraday
exposure.  Such limits would be necessary only if the size of the intraday
exposure and the condition of the correspondent indicated that there is a
significant risk that payments would not be made.

The rules are essentially designed to limit the exposure of banks upon the
failure of a large institution, but are stated more broadly.  "Exposure"
includes all extensions of credit, deposits or reverse repurchase agreements,
guarantees, acceptances, standby letters of credit, purchases or acceptance as
collateral of securities issued by a depository institution and other similar
transactions.  However, certain low-risk transactions, e.g., 


                                      19
<PAGE>   23
transactions secured by government securities or readily marketable collateral,
checks and other cash items in the process of collection and merger-related
exposures within one year after consummation, are excluded from the scope of
the proposed regulations.
        
Regulation F will be implemented in three phases.  Beginning on June 19, 1993,
banks must comply with the prudential standards.  Beginning June 19, 1994,
credit exposures to less-than-adequately capitalized institutions should not
exceed 50% of the bank's total capital.  Regulation F will be fully effective
starting June 19, 1995.

         Other Proposed Regulations under FDICIA

Section 304 of FDICIA requires the federal banking agencies to adopt uniform
regulations prescribing standards for real estate lending, including extensions
of credit secured by real estate or made for the purpose of financing the
construction of buildings or other improvements.  The agencies' proposal
establishes uniform loan-to-value ("LTV") ratio limitations on certain real
estate lending.  The LTV ratio is obtained by dividing the total amount of
credit to be extended by the appraised value or evaluation of the property at
the time the credit is originated.  Senior liens would be included in the
calculation when appropriate.

The banking agencies have solicited comment under Section 304 of FDICIA on two
(2) alternative LTV ratio measures, one of which would allow individual
institutions to establish prudent lending standards and the other of which
calls for uniform standards to be promulgated by the agencies.  In general, the
proposal allowing individual institutions to set LTV standards internally
allows for greater flexibility.  In addition, the agencies have solicited
comment on whether the final regulations may distinguish between classes of
institutions based on their financial and managerial strength.  Given the broad
range of the comments solicited and the variation in the alternate proposals,
the ultimate form of any regulation adopted and its effect on the Bank is
impossible to predict.  The Federal Reserve Board has stated that it intends to
propose in the near future real estate lending guidelines for bank holding
companies and non-bank subsidiaries thereof.

FDICIA requires the federal banking agencies to prescribe standards relating to
certain operational and managerial matters relating to internal controls, loan
documentation, credit underwriting, interest rate exposure, asset growth and
other matters, and also to prescribe standards relating to asset quality and
compensation.  The regulations are to be effective on the earlier of the date
on which final regulations become effective or December 1, 1993.  The agencies
recently published a joint advance notice of proposed rulemaking concerning the
new safety and soundness standards in which they solicited comments on a broad
range of issues.  Among other matters, the agencies noted that FDICIA requires
them to prescribe standards specifying a maximum ratio of classified assets to
capital, minimum earnings sufficient to absorb losses without impairing
capital, minimum ratios of market value to book value for

                                      20
<PAGE>   24
publicly traded shares (to the extent feasible), and such other asset quality,
earnings and valuation standards as the agency determines to be appropriate.

The agencies expressed the view in their notices that the market price of
depository institutions' publicly traded common stock, like the stock price of
all companies, varies with the actual or perceived financial health and
earnings power of the individual institution and the relative attractiveness of
stocks in general as compared to alternative investments.  Thus, the agencies
sought comment on whether it would be feasible to prescribe a standard relating
to a minimum ratio of market values to book values and whether any such minimum
ratio might encourage undesirable behavior by publicly traded depository
institutions and whether any such ratio should be tied to an industry or market
index.

         Under FDICIA, if an institution is determined to fail to meet any
standard, then the federal bank agencies can require the submission of
corrective plans.  If an institution fails to submit or implement a corrective
plan, the agencies are empowered to take various actions, including actions to
prohibit asset growth or require increases in equity.  In certain
circumstances, it appears that in the future institutions which are not in
compliance with the finalized safety and soundness standards may become subject
to the Prompt Corrective Action standards discussed above.  The advance notice
gives little indication of the form or content of eventual proposed regulations
in these areas and, accordingly, no prediction can be made at this time as to
these matters or their effect on the Bank or Company.

Financial Institutions Reform, Recovery, and 
Enforcement Act of 1989

The Financial Institutions Reform, Recovery, and Enforcement Act of 1989
("FIRREA") was enacted on August 9, 1989.  Among the many major changes made by
this law is a measure requiring the FDIC to assume responsibility for insuring
the deposits of financial institutions formerly insured by the Federal Savings
and Loan Insurance Corporation.  FIRREA established the Bank Insurance Fund and
the Savings Association Insurance fund as separate insurance funds which are
administered by the FDIC.


FIRREA also strengthened the FDIC'S regulatory enforcement authority in the
following ways:  (i) it expanded the categories of persons over whom
enforcement powers may be exercised; (ii) it reduced the threshold for the
imposition of civil monetary penalties, including allowing such penalties to be
imposed for an inadvertent failure to file a regulatory report in a timely
fashion; (iii) it substantially increased criminal and civil monetary
penalties; (iv) it added remedies, including "reimbursement" by parties
committing a wrong and orders requiring the sale of assets; (v) it enhanced
provisions for immediate remedies; (vi) it expanded the FDIC's powers to
appoint conservators and receivers; and (vii) it allows the FDIC to proceed
against "commonly controlled insured financial institutions" in the

                                      21



<PAGE>   25
event that the FDIC is required to provide assistance to a troubled "sister"
financial institution.

FIRREA also provides that banks which (i) have been chartered less than two (2)
years, (ii) have undergone a change of control within the preceding two years,
(iii) are not in compliance with minimum capital requirements, or (iv) have
been determined by the appropriate banking agency to be in a troubled
condition, are required to notify the appropriate banking agency of the
proposed addition of any individual to the board of directors or the employment
of any individual as a senior executive officer, at least thirty (30) days
before such action becomes effective.  The appropriate banking agency is then
empowered to disapprove any such addition or employment.  FIRREA prohibits a
bank from entering into a written or an oral contract with any person to
provide goods, products, or services to or for the benefit of the bank which
would jeopardize the safety or soundness of the bank.


Other legislation has been or may be proposed to the United States Congress and
the California Legislature and regulations may be proposed by the Federal
Reserve Board, the Comptroller and the FDIC which could affect the business of
the Bank.  Management of the Bank cannot predict whether such pending or
proposed legislation or regulations will be adopted and cannot predict the
effect such proposed legislation or regulations may have on its business.

Impact of Tax Reform Act of 1986 and Recent Tax Legislation

The Tax Reform Act of 1986 ("1986 Act") made sweeping changes to the federal
tax laws.  Additional tax law changes were made in the Omnibus Reconciliation
Act of 1987 ("1987 Act"), the Technical and Miscellaneous Revenue Act of 1988
("1988 Act"), the Revenue Reconciliation Act of 1989 ("1989 Act"), the Revenue
Reconciliation Act of 1990 ("1990 Act"), and the Comprehensive National Energy
Policy Act of 1992 (the "Energy Tax Act").  The most significant changes in the
taxation of commercial banks enacted under these laws include the following:

         1.      Corporate tax rates.  For tax years beginning on or after July
1, 1987, for most corporations taxable income is taxed at a rate of 34 percent,
decreased from 46 percent under prior law.


         2.      Corporate alternative minimum tax.  The 1986 Act enacted an
alternative minimum tax ("AMT").  In contrast to the corporate add-on minimum
tax under prior law, the AMT substantially increases a corporation's federal
income tax base by (a) expanding the number of preference items subject to tax
and (b) applying various adjustments to regular taxable income.  Generally, a
corporation will be subject to the AMT to the extent the tentative minimum tax
exceeds the corporation's regular tax liability.  The tentative minimum tax is
equal to (a) 20 percent of the excess of a corporation's "alternative minimum
taxable income" ("AMTI") over an exemption amount, less (b) the alternative
minimum foreign tax credit.  Generally, AMTI is defined as taxable income
computed with

                                      22
<PAGE>   26
special adjustments and increased by the amount of tax preference items for a
tax year.

Effective for tax years beginning after 1989, a special adjustment for
"adjusted current earnings" ("ACE") is made.  This adjustment replaced the
"book income" adjustment that was effective for tax years beginning in 1987
through 1989.  The ACE adjustment is equal to three-fourths of the excess of
ACE over AMTI (determined without regard to this adjustment and the AMT net
operating loss).  Generally, ACE is computed by adjusting AMTI to reflect the
rules applicable in computing corporate earnings and profits for federal income
tax purposes; adjustments are made for depreciation, for inclusion of certain
items otherwise excluded from taxable income, for disallowance of certain
deductions otherwise allowed in computing taxable income, and other items.

The 1989 Act (a) modified the method of calculating depreciation for purposes
of determining ACE; (b) modified the amount of the dividends received deduction
available in determining ACE; (c) provided that in certain cases, the
installment method of reporting gain may be used for ACE purposes; and (d) made
various technical changes to the definition of ACE.  The 1990 Act made various
technical changes to the ACE provisions, and in 1991, the Treasury promulgated
final regulations providing detailed rules for calculating the ACE adjustment.

In addition to the ACE adjustment, for purposes of determining AMTI, a
corporation is required to compute its depreciation allowance using a slower
depreciation rate than that used in computing regular taxable income.  Also,
special adjustments are made in computing a net operating loss, and generally a
net operating loss deduction cannot exceed 90 percent of AMTI.  Further,
tax-exempt interest on certain private activity bonds issued after August 7,
1986, constitutes a tax preference increasing AMTI.  Finally, the 1990 Act and
the Energy Tax Act made various technical changes to the AMT.

         3.      Bad debt deduction.  The 1986 Act required a bank with average
adjusted bases of all assets exceeding $500 million ("large bank") to compute
its bad debt deduction using the specific charge-off method.  Under that
method, a deduction is taken at the time the debt becomes partially or wholly
worthless.  Under prior law, a large bank also could use one of two reserve
methods, under which a bad debt deduction was computed according to the amount
added to a reserve set aside for bad debts.  The 1986 Act, as modified by the
1990 Act, continued to permit a bank not meeting the definition of a large bank
to use either the specific charge- off method or the "experience" reserve
method, under which the addition to bad debt reserve is based on the bank's
actual loss experience for the current year and five preceding years.

In 1992 the Treasury promulgated final regulations which permit a bank to elect
to establish a conclusive presumption that a debt is worthless, based on
applying a single set of standards for both regulatory and tax accounting
purposes.

                                      23

<PAGE>   27

         4.      Interest incurred for tax-exempt obligations.  Generally,
taxpayers are not allowed to deduct interest on indebtedness incurred to
purchase or carry tax-exempt obligations.  Prior to the 1986 Act, this
provision generally did not apply to interest paid by banks or other financial
institutions with respect to debts incurred in the ordinary course of the
bank's business.  Banks were subject, however, to a 20 percent disallowance of
such interest in certain cases.

The 1986 Act denies a deduction to banks for the portion of the bank's interest
that is allocable to tax-exempt obligations acquired by the bank after August
7, 1986.  The 20 percent disallowance of pre-1986 Act law continues to apply to
tax-exempt obligations acquired between January 1, 1983, and August 7, 1986.  A
special exception applies to a "qualified tax-exempt obligation," which
includes any tax-exempt obligation that (a) is not a private activity bond and
(b) is issued by an issuer that reasonably anticipates it will issue not more
than $10 million of tax-exempt obligations (other than certain private activity
bonds) during the calendar year.  Qualified tax-exempt obligations are treated
as acquired before August 8, 1986; thus, interest expense allocable to such
bonds continues to be deductible, subject to the 20 percent disallowance.

         5.      Net operating losses.  Under the 1986 Act, a bank is permitted
to carry a net operating loss ("NOL") back to the prior three tax years and
forward to the succeeding fifteen tax years, as opposed to the ten-year
carryback and five-year carryforward periods of prior law.  The prior law
periods were retained, however, to the extent the NOL of a commercial bank is
attributable to a bad debt deduction taken under the specific charge-off
method.  This special rule applies to NOLs for tax years beginning after
December 31, 1986, and before January 1, 1994.  The 1990 Act clarified that a
commercial bank's bad debt loss is treated as a separate NOL to be taken into
account after the remaining portion of the NOL for the year.

         6.      California tax laws.  A commercial bank is subject to the
California franchise tax.  The applicable tax rate is higher than that applied
to general (non-financial) corporations because it includes an amount "in lieu"
of many other state and local taxes and license fees payable by such
corporations but generally not payable by banks and financial corporations.
The bank tax rate for income years ending in 1989, 1990 and 1991 was 10.741%.
For income years ending after 1991 and before December 31, 1995, the rate is
the franchise tax rate applicable to general corporations (currently 9.3%) plus
the in-lieu rate, but the total rate cannot exceed 11.7%.  The in-lieu rate is
computed under a formula based on the amounts of personal property taxes,
business license taxes, and California income reported for general
corporations, and must be at least 1.3%.  For income years ending on or after
December 31, 1995, the applicable franchise tax rate will be the general
corporate rate plus 2%, with no ceiling.  

For income years beginning after 1987, California substantially adopted the 
federal AMT, subject to modifications for the ACE

                                      24
<PAGE>   28
adjustment, computation of NOLs, tax preference treatment for tax-exempt
interest, and certain other items.  Generally, a bank is subject to California
AMT in an amount equal to the sum of (a) seven percent of AMTI (computed for
California purposes) over an exemption amount and (b) the excess of the bank
tax rate over the general corporation tax rate applied against net income for
the taxable year, unless the bank's regular tax liability is greater.

California permits a bank to compute its deduction for bad debt losses under
either the specific charge-off method or according to the amount of a
reasonable addition to a bad debt reserve.  Regulations provide detailed rules
for determining the deduction under either method.

California has incorporated the federal NOL provisions, subject to significant
modifications.  Generally, NOLs arising in income years beginning before 1987
or after January 1, 1997 are not allowed.  No carryback is permitted, and only
fifty percent of the NOL for any income year may be carried forward.  Under
1991 legislation, NOL carryover deductions have been suspended for income years
beginning in calendar years 1991 and 1992, although the carryover period of
fifteen years in certain cases is extended for two years for NOL deductions
denied because of the suspension period.

The various laws discussed herein contain other changes that could have a
significant impact on the banking industry.  The effect of these changes is
uncertain and varied, and it is unclear to what extent any of these changes may
influence the Bank's operations or the banking industry generally.

In addition, on February 25, 1993, the Treasury Department released a Summary
of Administration's Revenue Proposals.  It is unclear whether these proposals
will be enacted into law, or what impact these proposals will have on the
operations of the Bank.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

Capital

During 1992, the Bank's capital net of dividends paid increased by $3,233,279
or 12.83%, compared to an increase of $2,794,593 or 12.48% in 1991, and an
increase of $2,925,612 or 15.03% in 1990.  Sources of additional capital in
each of the periods were retained earnings, exercise of stock options and
purchases of new stock by the Bank's profit sharing plan.  The Consolidated
Statement of Changes in Shareholders' Equity in the financial statements
reflects the detailed changes.

It is the intention of the Bank to continue capital augmentation through
earnings retention net of dividends in future years.

Liquidity

Historically, the Bank's balance sheet has shown a high degree of liquidity.
The following table shows balance sheet proportions for the years ending
December 31, 1992, December 31, 1991 and December 31, 1990:

Bank assets containing a high degree of liquidity are Cash & Due from Banks,
Investment Securities and Federal Funds sold.  In 1992, those assets comprised
33.80% of the Bank's assets compared to 35.86% in 1991 and 36.01% in 1990.

A principal source of liquidity is new deposit generation.  Until 1987, loan
generation had lagged deposit growth.  In 1992, loan growth exceeded deposit
growth.  In the following table, loans include bankers' acceptances.  Growth
rates for the last three years are shown in the following table:

The investment portfolio is another source of liquidity.  While a portion of
the portfolio is intended to be a long term investment, a portion is invested
in short-term obligations pending re-employment of these funds in the loan
portfolio or for deposit withdrawals.  As of December 31, 1992, bonds totaling
$1,455,488 mature within one year.  Additionally, at December 31, 1992, the
Bank owned bankers' acceptances totaling $1,983,378 which mature within 180
days.  The securities in the portfolio are freely marketable.

Other internal sources of liquidity are the retention of earnings and cash flow
generated in the loan portfolio.


External sources of liquidity include borrowings available to the Bank.  As of
December 31, 1992, the Bank has two lines of credit available totaling
$8,000,000 of which $3,000,000 is on an "as available" basis.  An additional
041 $5,000,000 is committed to June 30, 1993, and on which commitment fees have
been paid.

Results of Operations

Average deposits and other borrowings increased $36.5 million or 12.91% from
December 31, 1991 to December 31, 1992 compared to an increase of $51.5 million
or 20.11% from December 31, 1990 to December 31, 1991.  The increase was in all
deposit categories except time deposits with the largest part of the increase
in NOW and savings deposits, 21.18%.  Time deposits decreased $8.3 million, or
20.36%.  In the same period, average loans, net of bankers' acceptances,
increased by $38.2 million, or 22.35%.  The loan to deposit ratio increased to
66.50% on an average balance basis for the period ending December 31, 1992 from
64.21% for the period ending December 31, 1991.  On an average basis, the

resulting from growth is expressed as a volume change while the change in yield
is expressed as a rate change.  Nonaccrual loans are included in the
calculations.  Income and yields are on a fully taxable equivalent basis, using
the federal statutory income tax rate of 34% in 1992 and 1991.

Interest Rates and Interest Differentials

The primary source of the Bank's earnings is the net interest income, or
interest differential, which represents the difference between interest earned
on loans and investments and interest paid on deposits and short term
borrowings.  In 1992, net interest income on a taxable equivalent basis was
$17,005,000, an increase of 18.23% over the $14,383,000 net interest income in
1991.  This compares to a 6.88% increase in 1991 over net interest income of
$13,457,000 in 1990.

Net interest margin, interest paid as a percent of average earning assets,
increased twenty-seven basis points from 5.21% in 1991 to 5.48% in 1992.

Interest income on a taxable equivalent basis decreased from $26,583,000 in
1991 to $25,101,000 in 1992, which represents a 5.57% decrease.  Interest
income in 1991 had decreased 1.38% over interest income in 1990, which was
$26,956,000.  The decrease in 1992 was attributable to a decrease in yield from
9.63% to 8.09%.  The decrease in 1991 was also attributable to a decrease in
yield from 11.03% to 9.63%.  Overall, average rates earned on total earning
assets decreased by one hundred fifty four basis points.  A principal factor in
this decrease was the decrease in the




                                      35
<PAGE>   39
average daily prime rate from 8.46% to 6.25% in 1992.  Interest expense on
deposits and borrowed money decreased by $4,104,000, or 33.64% in 1992, as
compared to an decrease of $1,299,000, or 9.62%, in 1991.  Average balances of
interest-bearing liabilities increased by 12.91% in 1992, as compared to a
12.94% increase in 1991.  The average rate paid on interest bearing liabilities
decreased by one hundred seventy eight basis points from 4.32% in 1991 to 2.54%
in 1992.  In 1990, the average rate paid on interest-bearing liabilities was
5.40%.

Demand deposits increased $5,485,000, or 15.57% in 1992 compared to an increase
of $4,033,000 or 12.93% in 1991 over 1990.  The Bank's demand deposits are held
totally by corporate depositors doing business with the Bank.

Trust and fiduciary fees accounted for 52.54% of non-interest revenues in 1992
compared to 61.80% in 1991 and increased $490,000 or 31.49% in 1992.  The
market value of trust assets, upon which those fees are based, was $432 million
at year end. Service charges on deposit accounts increased 6.92% to $510,000.
The increase in service charge income is due to the increased number of deposit
accounts.  Other income is derived from safe

deposit rentals, traveler's cheque commissions, miscellaneous fees for other
bank services and gain on sale of securities.  Following a change in Investment
Policy in the second quarter of 1992, the entire U. S. Government portfolio was
sold, producing a net long term capital gain of $790,000.  In the first quarter
of 1992, the long term capital gains on calls of securities totaled $46,100.
Other income increased by 175.88%, or $853,000 in 1992.  Other income decreased
by 11.17% to $485,000 in 1991.  The decrease in 1991 is partially attributed to
the sale of a lease for $119,000 and the collection of residuals on leveraged
leases of $63,000 which were non-recurring events in 1990.

Non-interest expense increased $1,492,000 or 14.46% in 1992 over 1991.  This
compares to a 8.67% increase in 1991.

Salaries and employee benefits increased 11.16% over 1991 compared to a 10.15%
increase in 1991 over 1990.  The increases were due to pay increases and to
staff increases that were necessary to service the substantial increases in
deposits and earning assets.  Average full-time equivalent staff in 1992 was
120.7 compared to 112.5 in 1991, an increase of 7.29%.  Occupancy expense
increased $119,000, or 12.29%, in 1992, compared to a decrease of 4.54% in
1991.  The increase in 1992 was the result of the remodeling and refurbishing
of 250 Lytton Avenue, Palo Alto, which was completed in the second quarter of
1992.  Marketing expense increased by 14.17% in 1992 over 1991 compared to a
decrease of 22.09% in 1991.  The category of non-interest expense which
increased by the largest percentage was FDIC and OCC assessments which
increased $165,000 or 26.92% in 1992 over 1991 compared to an increase of
$280,000, or 84.08% in 1991 over 1990.  Increases in all categories of other

attributed primarily to the Bank's growth in 1992 and 1991.

Loan Portfolio

The Bank's loan portfolio is primarily composed of commercial and industrial
loans with adjustable or floating interest rates.  Adjustable rate loans
comprise approximately 93% of the portfolio, a factor that is critical to
maintaining a favorable spread between yields on earning assets and rates paid
on interest-bearing liabilities.  All loans are domestic.  There are no loan
concentrations which exceed 10% of outstanding loans.

Maturity Distribution and Rate Sensitivity Analysis

The following table shows the maturity distribution of loans on an average
balance basis for 1992, 1991 and 1990 (in thousands of dollars).

Loss Provision and Allowance for Possible Loan Losses

The allowance for possible loan losses, which provides for the risk of losses
inherent in the credit extension process, is increased by the provision for
possible loan losses charged to expense and decreased by the amount of
charge-offs net of recoveries.  There is no precise method of predicting
specific losses or amounts that ultimately may be charged off on particular
segments of the loan portfolio, especially in light of the current economic
environment.  The conclusion that a loan may become uncollectible, in whole or
in part, and be charged off against the allowance, is a matter of judgment.
Similarly, the adequacy of the allowance for possible loan losses and the level
of the related provision for possible loan losses can be determined only on a
judgmental basis, after full review, including consideration of the following:
economic conditions, borrowers' financial condition, evaluation of industry
trends, loans which are contractually current as to payment terms but
demonstrate a higher degree of risk as identified by management, continuing
evaluation of the performing loan portfolio, monthly review and evaluation of
potential problem loans identified as having loss potential, and bi-monthly
review by the Board of Directors.

The Bank has established an Allowance for Loan Losses to insure that it meets
statutory and regulatory requirements.  This policy provides for a systematic
and consistent approach to provide an adequate Allowance that is sufficient to
absorb all loan and lease losses.

The Bank provided $2,215,233 as an addition to the allowance for possible loan
losses in 1992.  In 1991, the provision was $875,000 and in 1990, $360,000.  At
December 31, 1992, the allowance for loan losses was $3,682,064 or 1.61% of
loans, net of banker's acceptances, compared to $1,828,025, or .94% of loans at
December 31, 1991, and $1,724,021, or 1.05% of loans at December 31, 1990.  Net
losses in 1992 were $361,194, compared to net losses of $770,996 in 1991 and
net losses of $425,763 in 1990.

Nonaccrual loans totaled $4,015,744 as of December 31, 1992 compared to
$578,725 as of December 31, 1991, an increase of 593.89%.  Nonaccrual loans
totaled $32,743 in 1990.  The substantial increase in 1992 is due to local
economic conditions and the depressed real estate market.  Net income not
realized as a result of the nonaccrual status totaled $108,442 in 1992 and
$12,253 in 1991.  It is the Bank's policy to place loans on nonaccrual at
ninety days delinquency or when it is identified as a potential collection
problem.

Other Real Estate Owned

As of December 31, 1992, the Bank owned three parcels of other real estate
totaling $1,111,805 compared to one parcel totaling $238,743 at December 31,
1991, an increase of 365.69%.  Other real estate owned at December 31, 1990
totaled $328,743.  Expenses associated with other real estate totaled $54,674
in 1992.  Comparable information is not available for 1991 and 1990.  In 1992,
one parcel was sold at a loss of $17,683.


Prior to recording a foreclosure, the Bank provides for any expected loss in
its allowance for loan losses.  At the time of foreclosure, any difference
between the loan balance and the fair value is charged to the allowance for
loan losses.  Foreclosed

property is recorded at the lower of its cost basis or fair value, less
estimated selling costs.  Any subsequent decline in value is charged directly
to the income statement.

Investment Portfolio

The Bank's investment portfolio decreased by $1,910,000 or 2.59% to $71,744,000
at December 31, 1992.  This compares to an increase of $10,075,000 in 1991.
The decrease in 1992 was due to increased loan demand.  The increase in 1991
was caused by the high degree of liquidity afforded by deposit inflows.  During
1992, proceeds of $35,453,000 were received and gross gains of $879,789 and
gross losses of $43,446 were realized upon the sale of the Bank's U. S.
Treasury and Agency security portfolios.  The proceeds were re-invested in U.
S. Agency securities with maturities of five to ten years.  At December 31,

                          Independent Auditors' Report


The Board of Directors
University National Bank & Trust Company:


We have audited the accompanying consolidated balance sheets of University
National Bank & Trust Company and subsidiary as of December 31, 1992 and
1991, and the related consolidated statements of income, changes in
shareholders' equity, and cash flows for each of the years in the three-year
period ended December 31, 1992.  These consolidated financial statements are
the responsibility of the Bank's management.  Our responsibility is to
express an opinion on these consolidated financial statements based on our
audits.

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

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of
University National Bank & Trust Company and subsidiary as of December 31,
1992 and 1991, and the results of their operations and their cash flows for
each of the years in the three-year period ended December 31, 1992, in
conformity with generally accepted accounting principles.

                    UNIVERSITY NATIONAL BANK & TRUST COMPANY

                   Notes to Consolidated Financial Statements

                        December 31, 1992, 1991 and 1990



(1)  Summary of Significant Accounting Policies

     (a)  General

     University National Bank & Trust Company and subsidiary (collectively the
     "Bank") commenced operations as a commercial bank in May 1980.  The Bank's
     main facility is located in downtown Palo Alto, with an additional banking
     floor in downtown Menlo Park and a trust representative office in Santa 
     Cruz.  Commercial banking services offered by the Bank include accepting 
     checking, savings, and time deposits and money fund deposit accounts; 
     advancing commercial, installment, and certain real estate loans; and 
     offering safe deposit services and other customary banking services to the
     retail, business, and professional community in and adjacent to Palo Alto. 
     In addition, the Bank offers trust and trustee services to employee 
     benefit plans, living trusts and testamentary trusts.

     (b)  Principles of Consolidation

     The consolidated financial statements of the Bank include the accounts of
     University National Bank & Trust Company and Lytton Corporation, its 
     wholly owned subsidiary.  All intercompany transactions have been 
     eliminated.

     (c)  Fair Value of Financial Instruments

     In 1992, the Bank adopted Statement of Financial Accounting Standards 
     No. 107 (SFAS 107), "Disclosures about Fair Value of Financial 
     Instruments."  SFAS 107 requires entities to disclose the fair value of 
     certain on-and off-balance sheet financial instruments in their audited 
     financial statements.  Fair value estimates, methods and assumptions are 
     set forth below for the Bank's financial instruments.

          (i)  Cash and Due from Banks, Federal Funds Sold, 
               Bankers' Acceptances Purchased, Accrued Interest 
               Receivable and Accrued Interest Payable

               The book value approximates fair value because of the short 
               maturity of these instruments.



                                                                     (Continued)

                    UNIVERSITY NATIONAL BANK & TRUST COMPANY

                   Notes to Consolidated Financial Statements





        (ii)  Investment Securities
      
              Fair value of long-term investments, except certain state and 
              municipal securities, is estimated based on bid prices published 
              in financial newspapers or bid quotations received from 
              securities dealers.  The fair value of certain state and 
              municipal securities is not readily available through market 
              sources other than dealer quotations, so fair value estimates
              are based on quoted market prices of similar instruments, 
              adjusted for differences between the quoted instruments and the 
              instruments being valued.
      
        (iii) Loans
      
              Fair values are estimated for portfolios of loans with similar 
              financial characteristics.  Loans are segregated by type such as 
              commercial, commercial real estate, residential mortgage and 
              consumer installment.  Each loan category is further segmented 
              into fixed and adjustable rate interest terms and by performing 
              or nonperforming categories.
      
              Fair value of performing fixed rate loans is calculated by 
              discounting scheduled cash flows on a pool basis through their 
              estimated maturity using estimated market discount rates that 
              reflect the credit and interest rate risk inherent in the loan. 
              The estimate of maturity is based on the Bank's historical 
              experience with repayments for each loan classification, 
              modified, as required, by an estimate of the effect of current 
              economic and lending conditions.
      
              For adjustable rate mortgage loans, the estimated average 
              repricing period is 180 days.  For adjustable rate commercial 
              loans, the average repricing period is one day.  Based on the 
              repricing frequency and minimal credit concerns for these loans,
              the book value of adjustable rate loans is used as an estimate
              of their fair value.
      
              Fair value for significant nonperforming loans is based on 
              estimated cash flows that are discounted using a rate 
              commensurate with the risk associated with the estimated cash 
              flows.  Assumptions regarding credit risk, cash flows, and 
              discount rates are judgmentally determined using available 
              market information and specific borrower information.
      
      

                                                                     (Continued)

                   Notes to Consolidated Financial Statements





         (iv)  Deposit Liabilities
 
               Fair value of deposits with no stated maturity, such as non-
               interest bearing demand deposits, NOW accounts, savings, and 
               insured money fund accounts, is equal to the amount payable on 
               demand as of December 31, 1992.  The fair value of certificates 
               of deposit is based on the discounted value of contractual cash 
               flows.  The discount rate is estimated using the rates 
               currently offered for deposits of similar remaining maturities.
 
         (v)   Commitments to Extend Credit and Standby Letters of Credit
 
               Fair value of commitments to extend credit is estimated using 
               the fees currently charged to enter into similar agreements, 
               taking into account the original terms of the agreements and the 
               present creditworthiness of the counterparties.  The fair value 
               of letters of credit is based on fees actually charged for 
               similar agreements in the prior year.  No fair value is assigned
               to loans in process.
 
         (vi)  Limitations
 
               Fair value estimates are made at a specific point in time, 
               based on relevant market information and information about the 
               financial instrument.  These estimates do not reflect any 
               premium or discount that could result from offering for sale at 
               one time the Bank's entire holdings of a particular financial 
               instrument.  Because no market exists for a significant portion 
               of the Bank's financial instruments, fair value estimates are 
               based on judgments regarding future expected loss experience, 
               current economic conditions, risk characteristics of various 
               financial instruments, and other factors.  These estimates are 
               subjective in nature and involve uncertainties and matters of 
               significant judgment and therefore cannot be determined with 
               precision.  Changes in assumptions could significantly affect 
               the estimates.
 


                                                                     (Continued)

                    UNIVERSITY NATIONAL BANK & TRUST COMPANY

                   Notes to Consolidated Financial Statements





                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.  
                For example, the Bank has a substantial trust department that 
                contributes net fee income annually.  The trust department is
                not considered a financial instrument, and its value has not 
                been incorporated into fair value estimates.  Other significant 
                assets and liabilities that are not considered financial assets 
                or liabilities include deferred taxes and buildings, furniture 
                and equipment.  In addition, the tax ramifications related to 
                the realization of unrealized gains and losses can have a 
                significant effect on fair value estimates and have not been 
                considered in the fair value estimates.

     (d)  Investment Securities

     Investment securities are those securities which management intends to 
     hold to maturity based on currently foreseeable conditions.  These 
     securities are stated at cost adjusted for amortization of premiums and 
     accretion of discounts, using methods approximating the interest method.  
     Gains or losses on disposition are based on the net proceeds and adjusted 
     carrying amount of the securities sold, using the specific identification 
     method.

     (e)  Loans and Allowance for Loan Losses

     Loans are stated at the amount of unpaid principal net of undisbursed 
     funds, reduced by an allowance for loan losses.  Interest on commercial, 
     real estate, and consumer installment loans is accrued on a simple 
     interest method on daily balances of the principal amount outstanding.  
     The allowance for loan losses is established through a provision for loan 
     losses charged to expense.  Loans are charged against the allowance for 
     loan losses when management believes that the collectibility of principal 
     is unlikely.  The allowance is an amount that management believes will be 
     adequate to absorb possible losses on existing loans that may become 
     uncollectible, based on evaluations of loan collectibility and prior loan 
     loss experience.  These evaluations take into consideration such factors 
     as changes in the nature and volume of the loan portfolio, overall 
     portfolio quality, review of specific problem loans, and current economic 
     conditions that may affect the borrowers' ability to pay.  Regulatory 
     examiners may require the Bank to recognize additions to the allowance 
     based on their judgements about information available to them at the time 
     of their examinations.  Accrual of interest is discontinued and prior 
     accrued interest is reversed on a loan when the payment of interest or 
     principal is 90 or more days past due.

     Loan origination and commitment fees and certain direct loan origination
     costs are deferred and the net amount amortized as an adjustment of the 
     related loan's yield over its estimated life.



                                                                     (Continued)

                   Notes to Consolidated Financial Statements





     (f)  Buildings, Furniture and Equipment

     Buildings, furniture 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.

     (g) Income Taxes

     The Bank currently recognizes income tax expense based upon the deferred
     method.  Under this method, deferred income taxes are provided for timing
     differences between items of income or expense reported in the consolidated
     financial statements and those reported for income tax purposes.  These
     differences relate principally to depreciation of equipment, provision for
     loan losses and use of the accrual basis of accounting for financial
     statement purposes and the cash basis of accounting for income tax purposes
     in prior years.

     Statement of Financial Accounting Standards No. 109 (SFAS 109), "Accounting
     for Income Taxes," was issued by the FASB in February 1992.  SFAS 109 
     requires a change from the deferred method to the asset and liability 
     method of accounting for income taxes.  Under the asset and liability 
     method, deferred income taxes are recognized for the tax consequences of 
     "temporary differences" by applying enacted statutory tax rates applicable 
     to future years to differences between the financial statement carrying 
     amounts and the tax bases of existing assets and liabilities.  Under SFAS 
     109, the effect on deferred taxes of a change in tax rates is recognized 
     in income in the period that includes the enactment date.

     SFAS 109 is effective for fiscal years beginning after December 15, 1992.
     Upon adoption, the provisions of SFAS 109 may be applied without restating
     prior years' financial statements or may be applied retroactively by
     restating any number of consecutive prior years' financial statements.

     The Bank estimates that the adoption of SFAS 109 will not have a material 
     impact on the Bank's financial statements.

     (h)  Net Income Per Common Share

     Primary net income per common share is based on the weighted average number
     of common shares outstanding of 1,329,474 in 1992, 1,307,896 in 1991, and 
     1,289,068 in 1990, including the effect of stock options.  The net income 
     per common share for 1992 includes net shares issuable upon assumed 
     exercise of stock options using the "treasury stock method," which assumes
     that stock options are exercised at the beginning of the period and the
     proceeds from exercise are used to purchase common stock at average market
     prices.



                                                                     (Continued)

     In February 1991, the Bank purchased a building in Menlo Park which it had 
     previously leased.  The Bank leases its Santa Cruz trust office under a 
     noncancelable operating lease which expires in September 1995.  Upon 
     expiration, the Bank has one three year option remaining on the lease.  
     Should the Bank not extend the lease in 1995, the Bank has the right to 
     continue the lease on a month-to-month basis, and pay a monthly rent equal 
     to 125% of the monthly rent payable during the last month of the current 
     lease term.  Monthly rent is based on a minimum rental plus adjustments 
     for cost of living increases.

     At December 31, 1992, 52,500 shares were exercisable through January 22,
     2002 priced from $11.25 to $32.50.  At December 31, 1991, 53,326 shares 
     were exercisable through July 17, 2001 priced from $6.56 to $32.50.

     Tax benefits from early disposition of the stock by optionees under
     incentive stock options of $134,027 were credited to capital surplus in
     1991.

(8)  Outside Directors Stock Option Plan

     In January of 1992, the Board and shareholders of the Bank adopted a stock 
     option plan for its non-employee directors.  Options are granted at prices 
     per share not less than market price at date of grant.  The options are 
     exercisable beginning one year from the date of grant at 20% annually and 
     expire on January 22, 1998.  Options which terminate without being 
     exercised may be reissued.  Shares of common stock reserved for granting 
     of stock options were 11,000 at December 31, 1992.  During 1992, 9,000 
     shares were granted at a price of $24.75 per share.

(9)  Profit-Sharing Plan

     The Bank has a profit-sharing plan covering substantially all employees.
     Contributions are made to the plan at the discretion of the Bank's Board
     of Directors.  Plan contributions were $408,117, $321,615 and $336,509 for 
     the years ended December 31, 1992, 1991 and 1990, respectively.

(10) Commitments and Contingencies

     (a)  Financial Instruments with Off-Balance Sheet Risk

     The Bank is party to financial instruments with off-balance sheet 
     risk in the normal course of business to meet the financing needs
     of its customers.   Such 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 amounts recognized in the consolidated balance sheets.  The
     contractual amounts of these instruments  reflect the extent of
     involvement the Bank has in particular classes of financial instruments.

     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 
     the instruments.  The Bank uses the same credit policies in making 
     commitments and conditional obligations as it does for on-balance sheet 
     instruments.  The Bank controls the credit risk of these transactions 
     through credit approvals, limits, and monitoring procedures.
     




                                                                     (Continued)

                   Notes to Consolidated Financial Statements





     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.  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 marketable 
     securities, accounts receivable, inventory, property, plant, and 
     equipment, income-producing commercial properties and residential 
     properties.
     
     Standby letters of credit are written conditional commitments issued by the
     Bank to guarantee the performance of a customer to a third party.  Such
     guarantees are primarily issued to support public and private borrowing
     arrangements.  These guarantees are extended for less than five years and
     expire in decreasing amounts through 1997.  The credit risk involved in 
     issuing letters of credit is essentially the same as that involved in 
     extending loan facilities to customers.
     
     Of the standby letters of credit outstanding at December 31, 1992, 80% are
     unsecured, and 20% are 100% collateralized.
     
     The contract amount and estimated fair value of commitments to extend 
     credit and standby letters of credit at December 31, 1992 is as follows:

        Commitments to extend credit                        $73,128,342            599,600
        Standby letters of credit                             7,327,832             76,300
</TABLE>

     At December 31, 1991, the Bank had commitments to extend credit of 
     $80,410,239 and standby letters of credit of $8,047,791.
     
     Based on the historical experience of the Bank, management does not believe
     that it will be called upon to disburse all of the funds available under 
     these commitments.
     
     (b)  Concentration of Credit Risk

     The Bank grants residential, commercial and consumer loans to customers 
     located primarily in the northern California Bay Area.  Although the Bank 
     has a diversified portfolio, a substantial portion of its debtors' ability 
     to honor their contracts is dependent upon the economic sector of the 
     northern California Bay Area.

     (c)  Available Lines of Credit

     At December 31, 1992, the Bank had available an unused line of credit of
     $3,000,000 for Federal fund borrowings on an "as available" basis, and a
     $5,000,000 committed line of credit.  Any amounts drawn on the committed 
     line of credit will be collateralized by marketable securities having an 
     aggregate market value of not less than 125% of the loan amount.
     
(11) Trust Assets

     The trust department of the Bank held the following types of fiduciary
     assets, at cost:

</TABLE>

     The market value of the trust assets was approximately $431,994,000 and
     $460,583,000 at December 31, 1992 and 1991, respectively.  These assets
     are not beneficially owned by the Bank and, therefore, are not included
     in the accompanying balance sheets.

(12) Regulatory Matters

     The Bank is subject to the Office of the Comptroller of the Currency (OCC) 
     governing capital adequacy.  In 1989, the OCC adopted regulations for 
     determining capital adequacy which involve assigning assets to four broad 
     risk categories and establishing minimum capital ratios based on these 
     assignments.  The regulations were phased in over three years, and require 
     a ratio of capital to risk-weighted assets of 8.00% and a minimum Tier 1 
     ratio (as defined by the regulations) of 4.00% by December 31, 1992.  At 
     December 31, 1992, the bank qualified for the top capital category of 
     "well capitalized" under the regulations.

     Additionally, banking regulations limit the amount of dividends that may 
     be paid without prior approval by the Bank's regulatory agency.  Retained 
     earnings against which dividends may be paid without prior approval is 
     approximately $7,060,000 at December 31, 1992, subject to the minimum 
     capital ratio requirements noted above.

University National Bank & Trust Company (the "Bank") commenced business as a
general commercial bank on May 13, 1980.  The Bank's wholly-owned subsidiary,
Lytton Corporation, is inactive.  Consolidated financial statements are filed

                         NOTES TO FINANCIAL STATEMENTS

                          Quarter ended March 31, 1993


The financial statements included herein are unaudited.  The information
furnished herein reflects all adjustments which are, in the opinion of
management, necessary to a fair statement of the results of the interim period
ended March 31, 1993.


NOTE A - Summary of Significant Accounting Policies

Investment Securities

Investment securities, which are generally held to maturity, are stated at
cost, adjusted for the accretion of discounts and amortization of premiums
using the straight line method.

Loans

Loans are stated net of undisbursed funds.  Interest on commercial, consumer
installment and real estate loans is accrued on a simple interest basis.
Interest on loans is not accrued in those instances where management considers
principal amounts doubtful of collection.

Loan Fees

Nonrefundable fees for loan origination and commitments in excess of direct
costs of originating the loan or commitment are amortized over the life of the
loan using the straight line method.  Fees originated since 1988 are recognized
as income using the interest method as required by FASB 91.

Allowance for Loan Losses

The allowance for loan losses is established through charges to earnings in the
form of a provision for loan losses.  Loans which are determined to be
uncollectible are charged against this allowance, and subsequent recoveries, if
any, are credited to the allowance.

The allowance for loan losses is an amount that management believes will be
adequate to absorb possible losses on existing loans that may become
uncollectible, based on evaluations of the collectability of loans and prior
loan experience.  The evaluations take into consideration such factors as
changes in the nature and volume of specific problem loans and current or
anticipated economic conditions that may affect the borrowers' ability to pay.


                                       8

Premises and Equipment

Premises and equipment are stated at cost, less accumulated depreciation and
amortization.  Leasehold improvements are amortized over the life of the
respective lease or the estimated useful lives of the improvements, whichever
is the shorter period.  Depreciation is computed using the straight line method
over estimated useful lives of the assets.

Income Per Share of Common Stock

Net income per share is based upon the weighted average number of common shares
outstanding adjusted by the dilutive effect of stock options outstanding on a
fully diluted basis.

NOTE B - Provision for Income Taxes

No portion of income tax provision is attributable to foreign operations.  The
provision for income tax has been calculated taking into account the tax-exempt
status of portions of municipal bond income.  Of the federal statutory income
tax rate of 34%, the following are the components of the current quarter
provision:

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

Capital

During the first quarter of 1993, the Bank's capital increased by $1,041,456,
or 3.66%, compared to an increase of $648,751, or 2.78% in the same period of
1992.  Sources of additional capital in each of the periods were retained
earnings, exercise of stock options and purchases of new stock by the Bank's
profit sharing and 401K plans.  The Bank paid a dividend of thirty-five cents a
share to shareholders of record February 8, 1993, or a total of $466,285
compared to a dividend of fifty-five cents per share, or a total of $761,662 in
the same period of 1992.  Dividend payments were on a semi-annual basis in 1992
and on a quarterly basis in 1993.

The Bank is subject to Office of the Comptroller of the Currency's regulations.
In 1989, the Comptroller established risk-based capital guidelines for national
banks.  The Federal Reserve Board and the FDIC have issued similar guidelines
for bank holding companies and state banks.  The guidelines define Tier 1
Capital and Total Capital.  Tier 1 Capital consists of common and qualifying
preferred shareholder's equity and minority interests in equity accounts of
consolidated subsidiaries.  Total Capital consists of, in addition to Tier 1
Capital, mandatory convertible debt, preferred stock not qualifying as Tier 1
Capital, subordinated and other qualifying term debt and a portion of the
allowance for loan losses less the remaining 50% of investments in
unconsolidated subsidiaries.  The Tier 1 component must comprise at least 50%
of qualifying Total Capital.  Risk-based capital ratios are calculated with
reference to risk-weighted assets which include both on and off-balance sheet
exposures.  The minimum required qualifying total capital ratio is 8%, of which
at least 4% must consist of Tier 1 Capital.  At March 31, 1993, the Bank's Tier
1 Capital totaled $29,466,000 and Total Capital was $32,726,000.  The Bank's
Tier 1 capital to total risk weighted assets ratio was 11.30% and its Total
Capital to total risk weighted assets ratio was 12.55%.

It is the intention of the Bank to continue capital augmentation through
earnings retention net of dividends in future years.

Liquidity

Historically, the Bank's balance sheet has shown a high degree of liquidity.
The following table shows balance sheet proportions for the quarter ending
March 31, 1993 and for the years ending December 31, 1992 and December 31,
1991.

Totals may not add due to rounding.

Bank assets containing a high degree of liquidity are Cash & Due From Banks,
Investment Securities and Federal Funds Sold.  For the quarter ending March 31,
1993, those assets comprised 33.17% of the Bank's assets compared to 33.80% in
1992 and 35.86% in 1991.

A principal source of liquidity is new deposit generation.  Historically, loan
generation had lagged deposit growth.  That trend reversed in 1988 and
continued to the current quarter.  The loan to deposit ratio increased from
64.21% in 1991 to 66.50% in 1992 and  to 68.79% in the first quarter of 1993.
Growth rates for the first quarter of 1993 and for the years 1992 and 1991 are
shown in the following table.

</TABLE>

The investment portfolio is another source of liquidity.  While a portion of
the portfolio is intended to be a permanent investment, a portion is invested
in short-term obligations pending re-employment of these funds in the loan
portfolio or for deposit withdrawals.  As 

                                       11
<PAGE>   12
of March 31, 1993, the investment portfolio totaled $73,378,880.  Of that 
amount, $1,455,390, or 1.98% of the total portfolio matures  within one year.  
Additionally, the securities in the portfolio are freely marketable.  The 
portfolio contains $5,407,200 in unrealized appreciation.

Within the loan portfolio are investments in short term bankers acceptances
totaling $994,000 at March 31, 1993.  These acceptances all mature within 180
days.

Other internal sources of liquidity are the retention of earnings and cash flow
generated in the loan portfolio.

External sources of liquidity include borrowings available to the Bank.  As of
March 31, 1993, the Bank has two lines available totaling $8,000,000 of which
$5,000,000 is committed until June 30, 1993, and on which commitment fees have
been paid.  $3,000,000 is on an "as available" basis.

Indebtedness of Management

The Bank has had, and expects to have in the future, banking transactions in
the ordinary course of its business with directors, officers, principal
shareholders and their associates, on the same terms, including interest rates
and collateral on loans, as those prevailing at the same time for comparable
transactions with others, and which, in the opinion of the Bank's Management,
do not involve a greater risk of collectibility.  Furthermore, it is the Bank's
policy to preclude its executive officers from borrowing from the Bank and any
loan to a director must be approved by the entire Board of Directors.

The following table summarizes the loans to Directors and Principal Holders of
Equity Securities in the quarter ended March 31, 1993:

</TABLE>
During the period ended March 31, 1993, none of these loans became past due or 
was placed on non-accrual.

Results of Operations

In the quarter ended March 31, 1993, average daily assets increased by $25.7
million or 7.69% over the first quarter 1992 and increased by $1.3 million, or
less than 1%, over the fourth quarter of 1992.  Deposits and other borrowings
increased $22.5 million, or 7.35% 

                                       12
<PAGE>   13

over the first quarter of 1992 and decreased $329 thousand, or 0.09% over the 
fourth quarter of 1992.

The mix in earning assets reflects a increase in loan demand.  Loans, net of
banker's acceptances, as a percent of earning assets were 65.57% for the
quarter ended March 31, 1993, compared to 61.59% for the first quarter of 1992
and 63.75% for the fourth quarter of 1992.

Net Interest Income and Margin

In the three months ended March 31, 1993, net interest income on a fully
taxable equivalent basis decreased $6,000, or .13% from the preceding quarter
and increased $581,000, or 14.51%, over the same period in 1992.

Interest-earning assets averaged $320.4 million, an increase of $23.3 million,
or 7.82%, over the same period in 1992.  Interest earned on those assets
decreased $79,000, or 1.26%, for a total of $6,195,000 in this period.  The
composite fully taxable equivalent yield on interest-earning assets decreased
from 8.49% in the first quarter of 1992 to 7.78% in the current period.
Compared with the preceding period, interest on earning assets decreased
$109,000, or 1.73%.  Yields decreased twenty-one basis points from 7.99% to
7.78%.

Average interest-bearing liabilities increased by $22.5 million to $328.9
million, or 7.35% over the same period in 1992.  Interest expense decreased
$660,000, or 29.09%.  The composite average cost of funds decreased from 2.98%
to 1.97%.  In this quarter, compared to the prior quarter, the cost of funds
decreased by fourteen basis points from 2.11% to 1.97%.  Net interest margin
increased from 5.42% in the first quarter of 1992 to 5.82% in the fourth
quarter of 1992 and decreased to 5.76% in the current quarter.

Non-Interest Income

In this period, non-interest income increased $138,500, or 19.61% over the same
period in 1992 and decreased $40,200, or 4.55% from the prior period.
Non-interest income is derived from Trust Department fees, service charges on
deposit accounts, other fees and charges and safe deposit rentals.  In this
period, trust fees accounted for $553,200 or 65.46% of non-interest revenue.
Increases in non-interest income over the prior year are due to increased
volume of trust business.

Non-Interest Expense

Non-interest expense increased $437,000, or 15.25%, in this period compared to
the same period in 1992, and increased $143,200 or 4.53% over the prior period.
Overall increases in non-interest expense are due to increases in deposits and
earning assets and increased staff and other costs necessary to service this
growth.

Provision for Loan and Lease Losses

The Bank provided $300,000 for loan losses in this period compared to $300,000
in the first quarter of 1992 and to $225,000 in the fourth quarter of 1992.
The Bank's Reserve for Loan Losses is maintained at a level that Management
believes will be adequate to absorb possible losses. Management evaluations
take into consideration such factors as changes in the nature and volume of
specific problem loans and current economic conditions that may affect the
borrower's ability to repay.

The balance of the reserve for loan losses was $3,835,096 at March 31, 1993
compared to $3,682,064 at December 31, 1992 and to $2,092,140 at March 31,
1992.  Net losses totaled $146,967 in the first quarter of 1993 compared to
$35,885 in the first quarter of 1992 and to $282,065 in the fourth quarter of
1992.

Loans on non-accrual totaled $4,084,400 at March 31, 1993 compared to
$1,042,200 at March 31, 1992 and to $4,015,700 at December 31, 1992.  The
increases are due to deterioration in the local economy, particularly in real
estate.

Letters of Credit

At March 31, 1993, the Bank's commitments under unused letters of credit were
$7,897,000 of which 20% are reasonably expected to be exercised within the next
twelve months.  At March 31, 1992, such commitments totaled $7,509,000 and at
December 31, 1992, $7,328,000.

INTEREST RATES AND NET INTEREST DIFFERENTIAL

The major portion of the Bank's income results from the difference between
interest income derived from earning assets and interest expense paid on
liabilities incurred primarily for the funding of those assets.  The
difference is referred to as net interest income.  Net interest income
expressed as a percent of average total earning assets is referred to as
net interest margin.  Net interest income and net interest margin are
summarized in the following comparisons for the three months ended
March 31, 1993 over the same period in 1992 and for the three months
ended December 31, 1992.  Average balances are expressed in thousands of
dollars:

                         NOTES TO FINANCIAL STATEMENTS

                          Quarter ended June 30, 1993


The financial statements included herein are unaudited.  The information
furnished herein reflects all adjustments which are, in the opinion of
management, necessary to a fair statement of the results of the interim period
ended June 30, 1993.


NOTE A - Summary of Significant Accounting Policies

Investment Securities

Investment securities, which are generally held to maturity, are stated at
cost, adjusted for the accretion of discounts and amortization of premiums
using the straight line method.

Loans

Loans are stated net of undisbursed funds.  Interest on commercial, consumer
installment and real estate loans is accrued on a simple interest basis.
Interest on loans is not accrued in those instances where management considers
principal amounts doubtful of collection.

Loan Fees

Nonrefundable fees for loan origination and commitments in excess of direct
costs of originating the loan or commitment are amortized over the life of the
loan using the straight line method.  Fees originated since 1988 are recognized
as income using the interest method as required by FASB 91.

Allowance for Loan Losses

The allowance for loan losses is established through charges to earnings in the
form of a provision for loan losses.  Loans which are determined to be
uncollectible are charged against this allowance, and subsequent recoveries, if
any, are credited to the allowance.

The allowance for loan losses is an amount that management believes will be
adequate to absorb possible losses on existing loans that may become
uncollectible, based on evaluations of the collectability of loans and prior
loan experience.  The evaluations take into consideration such factors as
changes in the nature and volume of specific problem loans and current or
anticipated economic conditions that may affect the borrowers' ability to pay.

<PAGE>   29
 
Premises and Equipment
 
Premises and equipment are stated at cost, less accumulated depreciation and
amortization. Leasehold improvements are amortized over the life of the
respective lease or the estimated useful lives of the improvements, whichever is
the shorter period. Depreciation is computed using the straight line method over
estimated useful lives of the assets.
 
Income Per Share of Common Stock
 
Net income per share is based upon the weighted average number of common shares
outstanding adjusted by the dilutive effect of stock options outstanding on a
fully diluted basis.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

Capital

During the second quarter of 1993, the Bank's capital increased by $723,219, or
2.45%, compared to an increase of $1,041,003, or 4.03% in the same period of
1992.  Sources of additional capital in each of the periods were retained
earnings, exercise of stock options and purchases of new stock by the Bank's
profit sharing and 401K plans.  The Bank paid a dividend of thirty-five cents a
share to shareholders of record April 12, 1993, or a total of $466,845.  No
dividends were paid in the second quarter of 1992.  Dividend payments were on a
semi-annual basis in 1992 and on a quarterly basis in 1993.

The Bank is subject to Office of the Comptroller of the Currency's regulations.
In 1989, the Comptroller established risk-based capital guidelines for national
banks.  The Federal Reserve Board and the FDIC have issued similar guidelines
for bank holding companies and state banks.  The guidelines define Tier 1
Capital and Total Capital.  Tier 1 Capital consists of common and qualifying
preferred shareholders' equity and minority interests in equity accounts of
consolidated subsidiaries.  Total Capital consists of, in addition to Tier 1
Capital, mandatory convertible debt, preferred stock not qualifying as Tier 1
Capital, subordinated and other qualifying term debt and a portion of the
allowance for loan losses less the remaining 50% of investments in
unconsolidated subsidiaries.  The Tier 1 component must comprise at least 50%
of qualifying Total Capital.  Risk-based capital ratios are calculated with
reference to risk-weighted assets which include both on and off-balance sheet
exposures.  The minimum required qualifying total capital ratio is 8%, of which
at least 4% must consist of Tier 1 Capital.  At June 30, 1993, the Bank's Tier
1 Capital totaled $30,189,000 and Total Capital was $33,418,000.  The Bank's
Tier 1 capital to total risk weighted assets ratio was 11.69% and its Total
Capital to total risk weighted assets ratio was 12.94%.

It is the intention of the Bank to continue capital augmentation through
earnings retention net of dividends in future years.

Liquidity

Historically, the Bank's balance sheet has shown a high degree of liquidity.
The following table shows balance sheet proportions for the quarter ending June
30, 1993 and for the years ending December 31, 1992 and December 31, 1991.

Totals may not add due to rounding.

Bank assets containing a high degree of liquidity are Cash & Due From Banks,
Investment Securities and Federal Funds Sold.  For the quarter ending June 30,
1993, those assets comprised 34.83% of the Bank's assets compared to 33.80% in
1992 and 35.86% in 1991.

A principal source of liquidity is new deposit generation.  Historically, loan
generation has periodically lagged deposit growth.  The loan to deposit ratio
increased from 64.21% in 1991 to 66.50% in 1992 and decreased to 65.78% in the
second quarter of 1993.  Growth rates for the second quarter of 1993 and for
the years 1992 and 1991 are shown in the following table.

The investment portfolio is another source of liquidity.  While a portion of
the portfolio is intended to be a permanent investment, a portion is invested
in short-term obligations pending re-employment of these funds in the loan
portfolio or for deposit withdrawals.  As of June 30, 1993, the investment
portfolio totaled $70,158,968.  Of that amount, $1,395,393, or 1.99% of the
total portfolio matures

within one year.  Additionally, the securities in the portfolio are freely 
marketable.  The portfolio contains $5,953,000 in unrealized appreciation.

Within the loan portfolio are investments in short term bankers acceptances
totaling $7,053,000 at June 30, 1993.  These acceptances all mature within 180
days.

Other internal sources of liquidity are the retention of earnings and cash flow
generated in the loan portfolio.

External sources of liquidity include borrowings available to the Bank.  As of
June 30, 1993, the Bank has two lines available totaling $10,000,000 of which
$5,000,000 is committed until June 30, 1994, and on which commitment fees have
been paid.  $5,000,000 is on an "as available" basis.

Indebtedness of Management

The Bank has had, and expects to have in the future, banking transactions in
the ordinary course of its business with directors, officers, principal
shareholders and their associates, on the same terms, including interest rates
and collateral on loans, as those prevailing at the same time for comparable
transactions with others, and which, in the opinion of the Bank's Management,
do not involve a greater risk of collectibility.  Furthermore, it is the Bank's
policy to preclude its executive officers from borrowing from the Bank and any
loan to a director must be approved by the entire Board of Directors.

The following table summarizes the loans to Directors and Principal Holders of
Equity Securities in the quarter ended June 30, 1993:

Aggregate Amount of Outstandings at June 30, 1993              $1,320,918.26
</TABLE>

During the period ended June 30, 1993, none of these loans became past due or
was placed on non-accrual.

Results of Operations

In the quarter ended June 30, 1993, average daily assets increased by $26.5
million or 7.56% over the second quarter 1992 and increased by $17.7 million,
or 4.91%, over the first quarter of 1993.  Deposits and other borrowings
increased $17.6 million, or 5.34%


                                     13
<PAGE>   33

over the second quarter of 1992 and increased $23.8 million, or 7.37% over the
first quarter of 1993.

The mix in earning assets reflects a decrease in loan demand.  Loans, net of
banker's acceptances, as a percent of earning assets were 67.51% for the
quarter ended June 30, 1993, compared to 64.48% for the second quarter of 1992
and 70.85% for the first quarter of 1993.

Net Interest Income and Margin

In the three months ended June 30, 1993, net interest income on a fully taxable
equivalent basis increased $75,000, or 1.64% from the preceding quarter and
increased $549,000, or 13.35%, over the same period in 1992.

Interest-earning assets averaged $337.8 million, an increase of $17.5 million,
or 5.45%, over the same period in 1992.  Interest earned on those assets
decreased $33,000, or .52%, for a total of $6,298,000 in this period.  The
composite fully taxable equivalent yield on interest-earning assets decreased
from 8.07% in the second quarter of 1992 to 7.48% in the current period.
Compared with the preceding period, interest on earning assets increased
$103,000, or 1.66%.  Yields decreased thirty basis points from 7.78% to 7.48%.

Average interest-bearing liabilities increased by $23.8 million to $346.5
million, or 7.37% over the same period in 1992.  Interest expense decreased
$582,000, or 26.23%.  The composite average cost of funds decreased from 2.76%
to 1.90%.  In this quarter, compared to the prior quarter, the cost of funds
decreased by seven basis points from 1.97% to 1.90%.  Net interest margin
increased from 5.24% in the second quarter of 1992 to 5.76% in the first
quarter of 1993 and decreased to 5.53% in the current quarter.

Non-Interest Income

In this period, non-interest income increased $150,200, or 17.38% over the same
period in 1992 and increased $18,900, or 2.24% from the prior period.
Non-interest income is derived from Trust Department fees, service charges on
deposit accounts, other fees and charges and safe deposit rentals.  In this
period, trust fees accounted for $609,100 or 70.50% of non-interest revenue.
Increases in non-interest income over the prior year are due to increased
volume of trust business.

Non-Interest Expense

Non-interest expense increased $389,700, or 11.77%, in this period compared to
the same period in 1992, and increased $8,300 or .25% over the prior period.
Overall increases in non-interest expense are due to increases in deposits and
earning assets and increased staff and other costs necessary to service this
growth.

Provision for Loan and Lease Losses

The Bank provided $300,000 for loan losses in this period compared to
$1,015,200 in the second quarter of 1992 and to $300,000 in the first quarter
of 1993.  The Bank's Reserve for Loan Losses is maintained at a level that
Management believes will be adequate to absorb possible losses. Management
evaluations take into consideration such factors as changes in the nature and
volume of specific problem loans and current economic conditions that may
affect the borrower's ability to repay.

The balance of the reserve for loan losses was $3,952,216 at June 30, 1993
compared to $3,835,096 at March 31, 1993 and to $3,083,206 at June 30, 1992.
Net losses totaled $182,880 in the second quarter of 1993 compared to $24,167
in the second quarter of 1992 and to $146,967 in the first quarter of 1993.

Loans on non-accrual totaled $4,897,000 at June 30, 1993 compared to $3,894,700
at June 30, 1992 and to $4,084,400 at March 31, 1993.  The increases are due to
deterioration in the local economy, particularly in real estate.

Letters of Credit

At June 30, 1993, the Bank's commitments under unused letters of credit were
$7,238,000 of which 20% are reasonably expected to be exercised within the next
twelve months.  At June 30, 1992, such commitments totaled $7,088,000 and at
March 31, 1993, $7,897,000.

INTEREST RATES AND NET INTEREST DIFFERENTIAL

The major portion of the Bank's income results from the difference between
interest income derived from earning assets and interest expense paid on
liabilities incurred primarily for the funding of those assets.  The
difference is referred to as net interest income.  Net interest income
expressed as a percent of average total earning assets is referred to as
net interest margin.  Net interest income and net interest margin are
summarized in the following comparisons for the three months ended
June 30, 1993 over the same period in 1992 and for the three months
ended March 31, 1993.  Average balances are expressed in thousands of
dollars:

                         NOTES TO FINANCIAL STATEMENTS

                        Quarter ended September 30, 1993


The financial statements included herein are unaudited.  The information
furnished herein reflects all adjustments which are, in the opinion of
management, necessary to a fair statement of the results of the interim period
ended September 30, 1993.


NOTE A - Summary of Significant Accounting Policies

Investment Securities

Investment securities, which are generally held to maturity, are stated at
cost, adjusted for the accretion of discounts and amortization of premiums
using the straight line method.

Loans

Loans are stated net of undisbursed funds.  Interest on commercial, consumer
installment and real estate loans is accrued on a simple interest basis.
Interest on loans is not accrued in those instances where management considers
principal amounts doubtful of collection.

Loan Fees

Nonrefundable fees for loan origination and commitments in excess of direct
costs of originating the loan or commitment are amortized over the life of the
loan using the straight line method.  Fees originated since 1988 are recognized
as income using the interest method as required by FASB 91.

Allowance for Loan Losses

The allowance for loan losses is established through charges to earnings in the
form of a provision for loan losses.  Loans which are determined to be
uncollectible are charged against this allowance, and subsequent recoveries, if
any, are credited to the allowance.

The allowance for loan losses is an amount that management believes will be
adequate to absorb possible losses on existing loans that may become
uncollectible, based on evaluations of the collectability of loans and prior
loan experience.  The evaluations take into consideration such factors as
changes in the nature and volume of specific problem loans and current or
anticipated economic conditions that may affect the borrowers' ability to pay.


                                       10
<PAGE>   50

Premises and Equipment

Premises and equipment are stated at cost, less accumulated depreciation and
amortization.  Leasehold improvements are amortized over the life of the
respective lease or the estimated useful lives of the improvements, whichever
is the shorter period.  Depreciation is computed using the straight line method
over estimated useful lives of the assets.

Income Per Share of Common Stock

Net income per share is based upon the weighted average number of common shares
outstanding adjusted by the dilutive effect of stock options outstanding on a
fully diluted basis.

NOTE B - Provision for Income Taxes

No portion of income tax provision is attributable to foreign operations.  The
provision for income tax has been calculated taking into account the tax-exempt
status of portions of municipal bond income.  Of the federal statutory income
tax rate of 34%, the following are the components of the current quarter
provision:

                 Statutory tax rate                         100.0%
                 Tax effect of municipal income             (43.4%)

                 Current provision tax rate                  56.6%

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

Capital

During the third quarter of 1993 the Bank's capital increased by $540,288, or
1.79%, compared to an increase of $163,879, or .61% in the same period of 1992.
Sources of additional capital in each of the periods were retained earnings,
exercise of stock options and purchases of new stock by the Bank's profit
sharing and 401K plans.  The Bank paid a dividend of $0.35 per share to
shareholders of record July 12, 1993.  This compares to a dividend of $0.55 per
share in the same period of 1992.  Dividend payments were on a semi- annual
basis in 1992 and on a quarterly basis in 1993.

The Bank is subject to Officer of the Comptroller of the Currency's
regulations.  In 1989, the Comptroller established risk-based capital
guidelines for national banks.  The Federal Reserve Board and the FDIC have
issued similar guidelines for bank holding companies and state banks.  The
guidelines define Tier 1 Capital and Total Capital.  Tier 1 Capital consists of
common and qualifying preferred shareholder's equity and minority interests in
equity accounts of consolidated subsidiaries.  Total Capital consists of, in
addition to Tier 1 Capital, mandatory convertible debt, preferred stock not
qualifying as Tier 1 Capital, subordinated and other qualifying term debt and a
portion of the allowance for loan losses less the remaining 50% of investments
in unconsolidated subsidiaries.  The Tier 1 component must comprise at least
50% of qualifying Total Capital.  Risk-based capital ratios are calculated with
reference to risk-weighted assets which include both on and off-balance sheet
exposures.  The minimum required qualifying total capital ratio will be 8%, of
which at least 4% must consist of Tier 1 Capital.  At September 30, 1993, the
Bank's Tier 1 Capital totaled $30,730,000 and Total Capital was $33,865,000.
The Bank's Tier 1 capital to total risk weighted assets ratio was 12.25% and
its Total Capital to total risk weighted assets ratio was 13.50%.

It is the intention of the Bank to continue capital augmentation through
earnings retention net of dividends in future years.

Liquidity

Historically, the Bank's balance sheet has shown a high degree of liquidity.
The following table shows balance sheet proportions for the quarter ending
September 30, 1993 and for the years ending December 31, 1992 and December 31,
1991.

Totals may not add due to rounding.

Bank assets containing a high degree of liquidity are Cash & Due From Banks,
Investment Securities and Federal Funds Sold.  For the quarter ending September
30, 1993, those assets comprised 34.00% of the Bank's assets compared to 33.80%
in 1992 and 35.86% in 1991.

A principal source of liquidity is new deposit generation.  Historically, loan
generation has lagged deposit growth.    The loan to deposit ratio increased
from 64.21% in 1991 to 66.50% in 1992 and increased to 66.70% in the third
quarter of 1993.  Growth rates for the third quarter of 1993 and for the years
1992 and 1991 are shown in the following table.

The investment portfolio is another source of liquidity.  While a portion of
the portfolio is intended to be a permanent investment, a portion is invested
in short-term obligations pending re-employment of these funds in the loan
portfolio or for deposit withdrawals.  As of September 30, 1993, the investment
portfolio totaled $69,159,825.


                                       13
<PAGE>   53

Of that amount, $1,394,709, or 2.02% of the total portfolio matures  within one
year.  Additionally, the securities in the portfolio are freely marketable.

Other internal sources of liquidity are the retention of earnings and cash flow
generated in the loan portfolio.

External sources of liquidity include borrowings available to the Bank.  As of
September 30, 1993, the Bank has two lines available totaling $10,000,000 of
which $5,000,000 is committed until June 30, 1994, and on which commitment fees
have been paid.  $5,000,000 is on an "as available" basis.

Indebtedness of Management

The Bank has had, and expects to have in the future, banking transactions in
the ordinary course of its business with directors, officers, principal
shareholders and their associates, on the same terms, including interest rates
and collateral on loans, as those prevailing at the same time for comparable
transactions with others, and which, in the opinion of the Bank's Management,
do not involve a greater risk of collectibility.  Furthermore, it is the Bank's
policy to preclude its executive officers from borrowing from the Bank and any
loan to a director must be approved by the entire Board of Directors.

The following table summarizes the loans to Directors and Principal Holders of
Equity Securities in the quarter ended September 30, 1993:

Aggregate Amount of Outstandings at September 30, 1993          $1,447,585.97
</TABLE>

During the period ended September 30, 1993, none of these loans became past due
or was placed on non-accrual.

Results of Operations

In the quarter ended September 30, 1993, average daily assets increased by
$32.1 million or 9.27% over the third quarter 1992 and increased by $1.2
million, or .33%, over the second quarter of 1993.  Deposits and other
borrowings increased $29.2 million, or 9.19% over the third quarter of 1992 and
decreased $.3 million, or .08% over the second quarter of 1993.  The mix in
earning assets reflects changes in loan demand.  Loans as a percent of earning
assets were


                                       14
<PAGE>   54

66.26% for the quarter ended September 30, 1993, compared to 71.22% for the
third quarter of 1992 and 67.51% for the second quarter of 1993.

Net Interest Income and Margin

In the three months ended September 30, 1993, net interest income on a fully
taxable equivalent basis decreased $3,000, or 0.06% from the preceding quarter
and increased $363,000, or 8.45%, over the same period in 1992.

Interest-earning assets averaged $337.0 million, an increase of $28.5 million,
or 9.23%, over the same period in 1992.  Interest earned on those assets
increased $77,000, or 1.24%, for a total of $6,268,000 in this period.  The
composite fully taxable equivalent yield on interest-earning assets decreased
from 7.96% in the third quarter of 1992 to 7.38% in the current period.
Compared with the preceding period, interest on earning assets decreased
$30,000, or 0.48%.  Yields decreased ten basis points from 7.48% to 7.38%.

Average interest-bearing liabilities increased by $29.2 million to $346.8
million, or 9.19% over the same period in 1992.  Interest expense decreased
$286,000, or 15.08%.  The composite average cost of funds decreased from 2.37%
to 1.84%.  In this quarter, compared to the prior quarter, the cost of funds
decreased by six basis points from 1.90% to 1.84%.  Net interest margin
increased from 5.52% in the third quarter of 1992 to 5.53% in the second
quarter of 1993 and decreased to 5.48% in the current quarter.

Non-Interest Income

In this period, non-interest income increased $125,300, or 16.65% over the same
period in 1992 and increased $13,900, or 1.61% from the prior period.
Non-interest income is derived from Trust Department fees, service charges on
deposit accounts, other fees and charges and safe deposit rentals.  In this
period, trust fees accounted for $621,279 or 70.77% of non-interest revenue.
Increases in non-interest income over the prior year are due to increased
volume of trust business.

Non-Interest Expense

Non-interest expense increased $461,100, or 16.09%, in this period compared to
the same period in 1992, and increased $388,700 or 13.31% over the prior
period.  Overall increases in non-interest expense are due to increases in
deposits and earning assets and increased staff and other costs necessary to
service this growth.  A portion of the increase is due to increased FDIC
assessment rates.  FDIC assessment increased by $15,300 or 8.67% to $192,400 in
the current period.

Provision for Loan and Lease Losses

The Bank provided $500,000 for loan losses in this period compared to $675,000
provided in the third quarter of 1992 and to $300,000 in the second quarter of
1993.  The Bank's Reserve for Loan Losses is maintained at a level that
Management believes will be adequate to absorb possible losses. Management
evaluations take into consideration such factors as changes in the nature and
volume of specific problem loans and current economic conditions that may
affect the borrower's ability to repay.

The balance of the reserve for loan losses was $4,044,239 at September 30, 1993
compared to $3,952,216 at June 30, 1993 and $3,739,129 at September 30, 1992.
Net losses totaled $407,977 in the third quarter of 1993 compared to $182,880
in the second quarter of 1993 and to $19,077 in the second quarter of 1992.

Loans on non-accrual totaled $4,817,855 at September 30, 1993 compared to
$4,635,104 at September 30, 1992 and $4,897,000 at June 30, 1993.  These levels
of non-accrual loans are due to deterioration in the local economy,
particularly in real estate.

Letters of Credit

At September 30, 1993, the Bank's commitments under unused letters of credit
were $6,985,222 of which 20% are reasonably expected to be exercised within the
next twelve months.  At September 30, 1992, such commitments totaled $5,927,882
and at June 30, 1993, $7,238,000.

INTEREST RATES AND NET INTEREST DIFFERENTIAL
 
The major portion of the Bank's income results from the difference between
interest income derived from earning assets and interest expense paid on
liabilities incurred primarily for the funding of those assets. The difference
is referred to as net interest income. Net interest income expressed as a
percent of average total earning assets is referred to as net interest margin.
Net interest income and net interest margin are summarized in the following
comparisons for the three months ended September 30, 1993 over the same period
in 1992 and for the three months ended June 30, 1993. Average balances are
expressed in thousands of dollars:

            [UNIVERSITY NATIONAL BANK & TRUST COMPANY LETTERHEAD]




                                PROXY STATEMENT

         The accompanying proxy is solicited on behalf of the Board of
Directors of University National Bank & Trust Company, a national banking
association (the "Bank"), for use at the Annual Meeting of Shareholders to be
held at the Bank, 250 Lytton Avenue, Palo Alto, California at 4:30 p.m. on May
6, 1993.  The date of this Proxy Statement is March 24, 1993, the approximate
date on which this Proxy Statement and the accompanying form of proxy were
first sent or given to shareholders.

                              GENERAL INFORMATION

         Annual Report.  An annual report for the fiscal year ended December
31, 1992, is enclosed with this Proxy Statement.

         Voting Securities.  Only shareholders of record as of the close of
business on March 17, 1993, will be entitled to vote at the meeting and any
adjournment thereof.    At the close of business on that date, the Bank had
outstanding 1,333,842 shares of its $2.50 par value Common Stock (the "Common
Stock").

         Shareholders of Common Stock are entitled to one vote for each share
held, except that, in the election of Directors, each shareholder has
cumulative voting rights and is entitled to as many votes as shall equal the
number of shares held by him or her multiplied by the number of Directors to be
elected, and he or she may cast all of his or her votes for a single candidate
or may distribute his or her votes among any or all of the candidates as he or
she chooses.  The Company's bylaws provide that a majority of the outstanding
stock, represented in person by proxy, shall constitute a quorum for the
transaction of business at the meeting.

         Solicitation of Proxies.  The Bank will bear the entire cost of
preparing, assembling, printing and mailing proxy materials furnished by the
Board of Directors to shareholders.  Copies of proxy materials will be
furnished to brokerage houses, fiduciaries and custodians to be forwarded to
the beneficial owners of the Common Stock.  In addition to the solicitation of
proxies by use of the mail, some officers, Directors and regular employees of
the Bank may (without additional compensation) solicit proxies by telephone or
personal interview, the cost of which the Bank will bear.

         Voting of Proxies.  Any person giving a proxy in the form accompanying
this statement has the power to revoke or suspend it prior to its exercise.  It
is revocable prior to the meeting by an instrument revoking it or by a duly
executed proxy bearing a later date, delivered to the Secretary of the Bank.
It is suspended if the shareholder is present at the meeting and elects to vote
in person.  If the shareholder does not specify otherwise, such shares will be
voted (i) in favor of the nominees named herein for election as Directors (and,
in the proxy holders' discretion, such shares may be voted cumulatively as the
proxy holder deems appropriate so as to maximize the number of named nominees
that are elected), and (ii) at the proxy holders' discretion, on such other
matters, if any, which may come before the meeting (including any proposal to
adjourn the meeting).

         Stock Ownership of Certain Beneficial Owners and Management.  The
following table sets forth certain information, as of March 17, 1993, with
respect to the beneficial ownership of the Bank's Common Stock by (i) all
persons known by the Bank to be the beneficial owners of more than 5% of the
outstanding Common Stock of the Bank, (ii) each director and director-nominee
of the Bank, (iii) the Chief Executive Officer and the four other most highly
compensated executive officers of the Bank as of December 31, 1992 whose salary
and bonus for the year ended December 31, 1992 exceeded $100,000, and (iv) all
executive officers and directors of the Bank as a group.

                             ELECTION OF DIRECTORS

         The Bylaws of the Bank provide a procedure for nomination for election
of members of the Board of Directors, which procedure is printed in full in the
Notice of Annual Meeting of Shareholders accompanying this Proxy Statement.
Nominations not made in accordance therewith may, in his discretion, be
disregarded by the Chairman of the Meeting and, upon his instruction, the
inspector of elections shall disregard all votes cast for such nominee(s).

         The Bylaws of the Bank provide that the Board of Directors may fix the
number of Directors at any number between five (5) and twenty-five (25),
inclusive.  The Board of Directors, pursuant to its authority, has set the
number of Directors at ten (10) and all ten (10) Directors are to be elected at
this meeting to hold office until the next Annual Meeting of Shareholders and
until their successors are elected and qualify.  Unless otherwise cumulatively
voted so as to maximize the number of recommended nominees elected, all proxies
will be voted for the election of the ten (10) nominees recommended by the
Board of Directors, unless authority to vote for the election of Directors or
any Director is withheld.  All of the nominees are incumbent Directors of the
Bank.  If any of the nominees should unexpectedly decline or be unable to act
as a Director, the proxies may be voted for a substitute nominee to be
designated by the Board of Directors.  The Board of Directors has no reason to
believe that any nominee will become unavailable and has no present intention
to nominate persons in addition to or in lieu of those named below.

         If a quorum is present and voting, the ten nominees for Director
receiving the highest number of votes will be elected as Directors.
Abstentions and shares held by brokers that are present, but not voted because
the brokers were prohibited from exercising discretionary authority, i.e.,
"broker non-votes" will be counted as present for purposes of determining if a
quorum is present.

         The table below sets forth for each person nominated for election as a
Director certain information with respect to age and background.

         (1)     Potential gains are net of exercise price, but before taxes
                 associated with exercise.  These amounts represent certain
                 assumed rates of appreciation only, based on the Securities
                 and Exchange Commission's rules.  Actual gains, if any, on
                 stock option exercises are dependent on the future performance
                 of the Common Stock, overall market conditions and the
                 optionholders' continued employment through the vesting
                 period.  The amounts reflected in this table may not
                 necessarily be achieved.  One share of stock purchased at
                 $24.75 in 1992 would yield profits of $6.83 at 5% appreciation
                 over five years, or $15.56 per share at 10% appreciation over
                 the same period.

         (2)     Options granted under the Bank's Stock Option Plan (the
                 "Option Plan") are exercisable in five equal installments,
                 commencing one year after the date the option is granted.
                 Under the Option Plan, the Board retains discretion to modify
                 the terms of outstanding options.  See also "EXECUTIVE

CERTAIN TRANSACTIONS

         The Bank has had, and expects to have in the future, banking
transactions in the ordinary course of its business with the Bank's directors,
officers, principal shareholders and their associates, on the same terms,
including interest rates and collateral on loans, as those prevailing at the
same time for comparable transactions with others, and which, in the opinion of
the Bank's management, do not involve a greater risk of collectibility.
Furthermore, it is the Bank's policy to preclude its Executive Officers from
borrowing from the Bank and any loan to a Director must be approved by the
entire Board of Directors.

COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934

         Section 16(a) of the Securities Exchange Act of 1934 requires the
Bank's executive officers, directors and persons who beneficially own more than
10% of the Bank's Common Stock to file initial reports of ownership and reports
of changes in ownership with the Securities and Exchange Commission ("SEC").
Such persons are required by SEC regulations to furnish the Bank with copies of
all Section 16(a) forms filed by such persons.

         Based solely on the Bank's review of such forms furnished to the Bank
and written representations from certain reporting persons, the Bank believes
that all filing requirements applicable to the Bank's executive officers,
directors and more than 10% shareholders were complied with, except that annual
statements of ownership for fiscal 1992 for each of the Bank's executive
officers, reporting quarterly allocations of shares under the Bank's 401(k)
plan, were filed approximately two weeks late.

CHANGE OF CONTROL ARRANGEMENTS

         In the event of a merger or consolidation in which the Bank is not the
surviving corporation or the sale of substantially all of the Bank's assets,
all outstanding options under the Option Plan become immediately exercisable.




                                       9

COMPENSATION OF DIRECTORS

         Non-management directors of the Bank were reimbursed during 1992 at
the rate of $1,000 per month.  The total compensation paid to all
non-management directors in 1992 was $121,500.  Under the Bank's Outside
Directors Stock Option Plan, each Director received a one-time nonqualified
stock option for 1,000 shares of the Bank's Common Stock with an exercise price
equal to closing market price on date of grant on January 28, 1992.  The
options become exercisable in five equal annual installments, commencing one
year after the date of the grant.


            COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

         The Compensation Committee, after deliberation and review of a number
of comparable banks ranging in size from $221 million to $1,142 million in
average assets for 1991, felt that the Bank's compensation policy relative to
its Executive Officers should continue.  This policy encompasses the following:

         -       That none of the Executive Officers shall have an employment
                 contract nor a golden parachute.

         -       That each of the Executive Officers will have a salary base
                 that will be adjusted annually for a change in the CPI.
                 (Chairman and CEO's base for 1992 was $207,600, and the
                 adjustment for all Executive Officers for 1993 is 3.01%.)

         -       That the Executive Officers and Senior Vice Presidents will be
                 awarded a participation at the beginning of the fiscal year of
                 a bonus pool which in the aggregate will equal 10% of pre-tax
                 earnings.  (Chairman and CEO's allotment of the Bonus Pool for
                 1992 was 25%, and it will be 23.52% for 1993.)

         -       That the Bank allocated 10% of after tax profits before
                 reporting as a contribution to the Bank's Profit Sharing Plan,
                 which is allocated amongst the employees in accordance to each
                 employee's share of the total compensation of the Bank with
                 appropriate provisions to prevent top-heavy allocations to the
                 CEO.

         -       That options are considered to be a major ingredient in the
                 compensation package of the Executive Officers.  (The Chairman
                 and CEO received a new option of 6,000 shares at the
                 then-current market value as part of the 1993 compensation
                 package.)

         Because of the above, a major portion of the Executive Officers'
compensation is in fact variable and dependent upon the profit performance of
the Bank, i.e., if the Bank's profits are seriously down, the cash bonus pool
will be down by the same proportional amount, and the Executive Officers will
share in that loss.  On the other hand, the stronger the profits of the Bank
are, the higher the compensation to the participants in the pool are.  In
addition to the Chairman and CEO and the Executive Vice Presidents, all of the
Senior Vice Presidents also have allocations in the pool, but the percentage of
their compensation derived from the pool is much less.

         Since there are no employment contracts nor golden parachutes, the
Executive Officers' performance is always subject to review.

PART I.

ITEM 1.     BUSINESS

General

The Bank commenced operations on May 13, 1980.  Its principal banking office is
located at 250 Lytton Avenue, Palo Alto, California.  Since its formation, the
Bank has provided basic banking services and personal trust services to
individuals and business enterprises in the Palo Alto area.  Palo Alto is
located on the San Francisco Peninsula, approximately 30 miles south of San
Francisco, on the northern periphery of "Silicon Valley".

The Bank's primary service area is considered to be the communities of Palo
Alto, Menlo Park, Atherton and Portola Valley plus the unincorporated areas of
Ladera and Stanford University.  This primary service area is oriented towards
professional services, light industry, retail businesses and education.

The Bank considers its principal service a "banking relationship", the keystone
of which is a transaction account.  In the case of corporations, the
transaction account is a demand (checking) account.  In the case of
individuals, it is a Super-NOW account that pays interest, provided that
sufficient funds (i.e., either a daily minimum balance of $3,000, or an average
monthly balance of $6,000) are maintained.  Once a customer has established the
"relationship" with the Bank by opening a transaction account, that customer
may utilize all other Bank services, including money fund accounts,
certificates of deposit, safe deposit box rentals, cashier's checks, and
purchase U.S.  postage stamps, U.S. Savings Bonds and traveler's checks.  The
bank also makes available to qualified customers commercial, personal and real
estate loans, credit cards and standby letters of credit.  Through its
correspondents, the Bank is also able to offer limited international banking
and municipal bond trading services.

The Bank's Trust Department specializes in personal trust services and acts as
trustee on a range of employee benefit plans.  The Bank does not provide stock
transfer services.  The Bank opened a Trust Representative Office at 133
Mission Street, Santa Cruz on October 16, 1989.

The Bank opened an office at 800 Oak Grove, Menlo Park on November 15, 1989.
The Bank has automatic teller machines at its two offices and it issues an ATM
card which enables a customer to withdraw cash at over 25,000 offices of other
financial institutions world wide which are members of  Cirrus, Money Network,
Star System, and American Express.

The Bank employed 113 full time and 8 part-time staff at year end.

<PAGE>   5

Competition From Other Financial Institutions

The Bank considers its principal market area to be composed of the communities
of Palo Alto, Menlo Park, Atherton and Stanford.  According to the 1980 Census,
the aggregate population of these communities was 104,375.  The 1980 Census
further indicates that individuals 25 years old or older with four or more
years of college education totalled 57.5% of this market, versus 25.0% for the
San Francisco Bay Area and 19.6% for the State of California.  Individuals in
this primary market area who were 16 years old or older at the 1980 Census date
and who were employed as executives, administrators, managers or in a
professional specialty totalled 45.8%, as compared to 27.6% for the San
Francisco Bay Area and 25.1% for the State of California.

This market is very heavily serviced by financial institutions.  There are 32
commercial banking offices, 16 savings and loan offices, 22 securities
brokerage firms and 6 credit unions within this market area.  The 32 banking
offices alone had deposits from individuals, partnerships and corporations
totalling $2.3 billion as of June 30, 1990, compared to $1.6 billion at
December 31, 1983.  The Bank's market share was 2.17% on December 31, 1982,
3.88% on December 31, 1983, 4.49% on December 31, 1984, 5.31% on December 31,
1985, 6.42% on December 31, 1986, 8.50% on December 31, 1987, 9.8% on December
31, 1988, 10.67% on December 31, 1989, 10.86% on December 31, 1990 and 10.81%
on June 30, 1991.

With regard to loans, the Bank competes with other commercial banks, savings
and loan associations, consumer finance companies and other lending
institutions.  The Bank's Trust Department competes with the trust departments
of all the major banks operating within the Bank's primary service area.

In addition to its principal market area, the Bank considers as a secondary
market area, the surrounding communities of Los Altos, Mountain View,
Sunnyvale, and Santa Clara to the south and Redwood City, San Carlos, Belmont
and San Mateo to the north.  The Bank services customers in these areas by mail
or by the use of its five courier vans, which pick up non-cash deposits on
scheduled routes.

Outside its primary market area, the Bank competes with other national banks,
state banks, savings and loan associations, and credit unions for time and
savings deposits, other deposits, checking or draft accounts, and loans
throughout the San Francisco Bay area.  With respect to certain of its
services, including, but not limited to, loans, and particularly with respect
to securing funds available for deposits, the Bank competes with other
financial institutions such as insurance companies, consumer and business
finance or loan companies, industrial loan associations, real estate investment
trusts, pension funds, mortgage companies, and credit card organizations.  The
national equity and debt securities markets also compete for available funds.


                                      2
<PAGE>   6
Many of the Bank's competitors offer a comprehensive array of banking products
which the Bank has chosen not to offer, and these competitors thereby may have
a competitive advantage over the Bank.  Further, many of the Bank's competitors
have long established reputations and loyal customer bases.  However,
management of the Bank believes that the level of service which it provides in
the delivery of banking products to its customers contributes to the Bank's
ability to obtain market share in the face of such competition.

Many of the banks and other financial institutions, including regional money
center banks, with which the Bank competes, have capital and resources
substantially in excess of the capital and resources of the Bank.  Because
banks, including the Bank, are generally restricted from lending in excess of a
specified percentage of their capital base to one borrower, the Bank is
dependent upon its correspondent relationships for loan participations in order
to accommodate loan requests in excess of its legal lending limit.  The Bank's
legal limit on unsecured lending to any one entity was $3,915,854 on December
31, 1991.

To a certain extent, the Bank is also faced with competition from banks and
other institutions located in money centers outside of California, and from
foreign banks which maintain representative offices in California.

Commitments

As of December 31, 1991, and December 1990, the Bank's loan commitment by
category is as follows:

category of commitments is Commercial Loans ($54,848M [59.54%]).  The Bank
expects approximately 50% of these commitments to be drawn.  The Bank
anticipates that 50% of the commitments in the next largest category, Consumer
Revolving Loans ($26,555M [28.83%]) to be drawn.  Less than 5% of the
commitments are fixed rate commitments.

Commercial loan commitments are generally in the form of revolving lines of
credit with floating interest rates and typically mature within one year.  All
other commitments are on terms whereby prices of interest rates are to be
determined by market conditions prevailing at the time of exercise.

Concentration of Bank Deposits

There are no material portions of the Bank's deposit base obtained from a
single person or group of persons.  The Bank has no deposits of Federal, State
or Local governments other than a Treasury Tax and Loan account.  At December
31, 1990, the Bank had deposits totaling $35,783,431 from its Trust Department.
That total represents deposits of 565 individual trust accounts.

As of December 31, 1991, the Bank's deposit structure was as follows:

Foreign Sources of Business

There are no material deposit liabilities incurred from outside the Bank's
primary and secondary service areas.  The Bank has no brokered deposits and has
a policy not to accept any.  The Bank's loans are made primarily to
professionals, executives and privately held companies in the Bank's market
area.  From time to time, loan participations are purchased  from another bank.
As of December 31, 1991, participations totaling $1,323,526 were included in
the Bank's portfolio.

SUPERVISION AND REGULATION

The Bank is regulated and supervised by the Comptroller of the Currency (the
"Comptroller") and, therefore, is subject to periodic examination by the
Comptroller.  Deposits of the Bank's customers are insured by the FDIC up to
the maximum limit of $100,000.  As a national bank, the Bank is a member of the
Federal Reserve System and is subject to the regulations of the Federal Reserve
Board.

The regulations of those federal bank regulatory agencies govern most aspects
of the Bank's business and operations, including but not limited to: requiring
the maintenance of non-interest bearing reserves on deposits, limiting the
nature and amount of investments and loans which may be made, regulating the
issuance of securities, restricting the payment of dividends, regulating bank
expansion and bank activities and determining maximum rates of interest allowed
on certain deposits.

Effect of State Law

The laws of the State of California also affect the Bank's business and
operations.  For example, under 12 U.S.C. Section 36, the Comptroller may 
authorize a national bank to establish branch offices only to the extent 
allowable under state law for state banks.  Therefore, as California law 
presently permits a state bank to establish a branch office at any location in 
the state, a national bank may be similarly authorized to establish a branch 
by the Comptroller.  On a similar basis, 12 U.S.C. Section  85 provides that 
state law, in most circumstances, determines the maximum rate of interest 
which a national bank may charge on a loan.  As California law exempts all
state-chartered and national banks from the application of its usury laws,
national banks are also provided such an exemption pursuant to Section 85.

Capital Requirements

The Bank is subject to OCC regulations governing capital adequacy.  In 1989 the
OCC issued final guidelines for national banks, supplementing the existing
capital to assets leverage ratio requirement, which provided definitions of
qualifying capital and set forth minimum supervisory risk-based capital ratios
of capital to risk-weighted assets.  In doing so, the OCC announced that, while
leverage ratios serve as a useful tool for assessing capital adequacy, a
capital measure that is more explicitly and systematically sensitive to the
risk profiles of individual banks was called for.

The OCC guidelines provided a supplementary system for measuring and assessing
capital adequacy by establishing:

  (1)   a definition of core or "Tier 1" capital consisting of common
  shareholders' equity, non-cumulative perpetual preferred stock and minority
  interests in consolidated subsidiaries and a definition of supplementary of
  "Tier 2"


                                       6
<PAGE>   10
  capital consisting of allowances for loan and lease losses (up to a maximum
  of 1.5% of risk-weighted assets by year-end 1990 and 1.25% of risk-weighted
  assets by year-end 1992), cumulative perpetual and long-term preferred stock
  (original maturity of at least 20 years), hybrid capital instruments,
  including mandatory convertible debt securities, and term subordinated debt
  and intermediate-term preferred stock (original maturity of five years or
  more), with goodwill and certain other intangible assets deducted from Tier 1
  capital.

  (2)  a framework for assigning assets and off-balance sheet items to four 
  broad risk-weight categories (for example, 0% for cash and unconditionally
  guaranteed government securities, 20% for conditionally guaranteed government
  securities, 50% for performing residential real estate loans secured by first
  liens; and 100% for other assets, including all loans not qualifying for the
  50% category);

  (3)  a schedule for achieving a minimum risk-based capital ratio of 7.25% by
  December 31, 1990 and 8.0% by December 31, 1992 (with the Tier 1 component
  constituting at least 50% of total qualifying capital) and procedures for
  calculating a risk-based capital ratio; and

  (4)  transitional arrangements and a phase-in period through December 31, 1992
  allowing some Tier 2 capital components to be accorded core or Tier 1 status
  during the transitional period.

The risk-based capital ratio analysis established minimum supervisory
guidelines and standards.  It does not evaluate all factors affecting a bank's
financial condition, including overall interest rate exposure; liquidity,
funding and market risks; the quality and level of earnings; investment or loan
portfolio concentrations; the quality of loans and investments; the
effectiveness of loan and investment policies; and management's ability to
monitor and control financial and operating risks.  The capital adequacy
assessment of the OCC will, however, continue to include analysis of these
factors in assessing the condition of national banks.

At the time the risk-based capital framework was adopted, the OCC indicated
that the risk-based capital framework did not replace or eliminate the existing
leverage ratios but that, once the risk-based framework was implemented, the
consideration would be given to whether the existing definitions of capital for
leverage purposes and the minimum leverage ratios should be amended.  On
September 21, 1990, the OCC established new leverage guidelines, similar to
those adopted by the Board of Governors of the Federal Reserve for bank holding
companies, which would:

  (1)  for purposes of minimum leverage ratio requirements, replace the primary
  and total capital definitions with the Tier 1 (core) capital definition;

                                       7
<PAGE>   11

  (2)  eliminate the minimum 5.5% and 6% primary and total capital ratio
  requirements and replace them with a minimum 3% Tier 1 leverage capital ratio
  requirement for national banks that receive the highest composite regulatory
  rating and that are not anticipating or experiencing any significant growth;
  and

  (3)  require all other national banks to meet a minimum leverage ratio that is
  at least 100 to 200 basis points above this minimum, i.e. an absolute minimum
  leverage ratio of 4% for those national banks that do not receive the highest
  regulatory rating or are anticipating or experiencing significant growth.

A national bank's Tier 1 leverage ratio is calculated by dividing its Tier 1
capital by its average total assets.

December 31, 1991:

Management of the Bank believes that the Bank will continue to meet their
respective minimum capital requirements in the foreseeable future.

In certain circumstances, the Comptroller may determine that the capital ratios
for a national bank shall be maintained at levels which are higher than the
minimum levels required by the guidelines.  A national bank which does not
achieve and maintain adequate capital levels as required may be subject to
supervisory action by the Comptroller under the International Lending
Supervision Act through the issuance of a capital directive to ensure the
maintenance of required capital levels.  In addition, the Bank is required to
meet certain guidelines of the Comptroller concerning the maintenance of an
adequate allowance for loan and lease losses.

Payment of Dividends

The Bank's ability to make dividend payments is subject to statutory and
regulatory restrictions.

The Board of Directors of a national bank may declare the payment of dividends
from funds legally available therefor, depending upon the earnings, financial
condition and cash needs of the bank and general business conditions.  A
national bank may not, pursuant to 12 U.S.C. Section 56, pay dividends from its
capital, excluding the reserve for loan losses.  All dividends must be paid out
of net profits then on hand, after deducting losses and bad debts.  The payment
of dividends by a national bank is further restricted by 12 U.S.C. Section 60(a)
which prohibits a national bank from declaring a dividend on its shares of
common stock until its surplus fund equals the amount of capital stock or, if
the surplus fund does not equal the amount of the capital stock, until
one-tenth of the bank's net profits of the preceding half year in the case of

                                       9


<PAGE>   13
quarterly or semiannual dividends, or the preceding two consecutive half-year
periods in the case of an annual dividend, are transferred to the surplus fund.
Moreover, the approval of the Comptroller is required by 12 U.S.C. Section
60(b) for the payment of dividends if the total of all dividends declared
by the bank in any calendar year would exceed the total of its retained net
profits of that year combined with its net profits of the two preceding years,
less any required transfers to surplus or a fund for the retirement of any
preferred stock.

In addition to the requirements of 12 U.S.C. Sections 56 and 60,
guidelines adopted by the Comptroller set forth factors which are to be
considered by a national bank in determining the payment of dividends.  A
national bank, in assessing the payment of dividends, is to evaluate the bank's
capital position, its maintenance of an adequate allowance for loan and lease
losses, and the need to revise or develop a comprehensive capital plan,
complete with financial projections, budgets and dividend guidelines.
Therefore, the payment of dividends by the Bank is governed by the requirements
of 12 U.S.C. Sections 56 and 60, including consideration of the Bank's
maintenance of minimum required capital levels and an adequate allowance for
loan and lease losses.

Moreover, under the Federal Deposit Insurance Corporation Improvement Act of
1991, the Comptroller has broad authority to prohibit a national bank from
engaging in banking practices which it considers to be unsafe or unsound.  It
is possible, depending upon the financial condition of the national bank in
question and other factors, that the Comptroller may assert that the payment of
dividends or other payments by a bank is considered an unsafe or unsound
banking practice and therefore, implement corrective action to address such a
practice.

Accordingly, the future payment of cash dividends by the Bank will not only
depend upon the Bank's earnings during any fiscal period but will also depend
upon the assessment of the respective Boards of Directors of the capital
requirements of such institutions and other factors, including dividend
guidelines and the maintenance of an adequate allowance for loan and lease
losses.

Impact of Monetary Policies

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

                                       10
<PAGE>   14

The earnings and growth of the Bank are affected not only by general economic
conditions but also by the monetary and fiscal policies of the United States
and federal agencies, particularly the Federal Reserve Board.  The Federal
Reserve Board can and does implement national monetary policy, such as seeking
to curb inflation and combat recession, by its open market operations in United
States Government securities, by its control of the discount rates applicable
to borrowings by banks from the Federal Reserve System.  The actions of the
Federal Reserve Board in these areas influence the growth of bank loans,
investments and deposits and affect the interest rates charged on loans and
paid on deposits.  The nature and timing of any future changes in monetary
policies are not predictable.

Impact of Tax Reform Act of 1986 and Recent Tax Legislation

The Tax Reform Act of 1986 ("1986 Act") made sweeping changes to the federal
tax laws.  Additional tax law changes were made in the Omnibus Reconciliation
Act of 1987 ("1987 Act"), the Technical and Miscellaneous Revenue Act of 1988
("1988 Act"), the Revenue Reconciliation Act of 1989 ("1989 Act"), and the
Revenue Reconciliation Act of 1990 ("1990 Act").  The most significant changes
in the taxation of commercial banks enacted under these laws include the
following:

1.   Corporate tax rates.  For tax years beginning on or after July 1, 1987, 
for most corporations taxable income is taxed at a rate of 34 percent, 
decreased from 46 percent under prior law.

2.   Corporate alternative minimum tax.  The 1986 Act enacted an alternative
minimum tax ("AMT").  In contrast to the corporate add-on minimum tax under
prior law, the AMT substantially increases a corporation's federal income tax
base by (a) expanding the number of preference items subject to tax and (b)
applying various adjustments to regular taxable income.  Generally, a
corporation will be subject to the AMT to the extent the tentative minimum tax
exceeds the corporation's regular tax liability.  The tentative minimum tax is
equal to (a) 20 percent of the excess of a corporation's "alternative minimum
taxable income" ("AMT") over an exemption amount, less (b) the alternative
minimum foreign tax credit.  Generally, AMTI is defined as taxable income
computed with special adjustments and increased by the amount of tax
preferences for a tax year.

Effective for tax years beginning after 1989, a special adjustment for
"adjusted current earnings" ("ACE") is made.  This adjustment replaced the
"book income" adjustment that was effective for tax years beginning in 1987
through 1989.  The ACE adjustment is equal to three-fourths of the excess of
ACE over AMTI (determined without regard to this adjustment and the AMT net
operating loss). Generally, ACE is computed by adjusting AMTI to reflect the
rules applicable in computing corporate earnings and profits for federal income
tax purposes; adjustments are made for depreciation, for inclusion of certain
items otherwise excluded from taxable income,

                                      11

<PAGE>   15
for disallowance of certain deductions otherwise allowed in computing taxable
income, and other items.

The 1989 Act (a) modified the method of calculating depreciation for purposes
of determining ACE; (b) modified the amount of the dividends received deduction
available in determining ACE; (c) provided that in certain cases, the
installment method of reporting gain may be used for ACE purposes; and (d) made
various technical changes to the definition of ACE.  The 1990 Act made various
technical changes to the ACE provisions, and in 1991, the Treasury promulgated
final regulations providing detailed rules for calculating the ACE adjustment.

In addition to the ACE adjustment, for purposes of determining AMTI, a
corporation is required to compute its depreciation allowance using a slower
depreciation rate than that used in computing regular taxable income.  Also,
special adjustments are made in computing a net operating loss, and generally a
net operating loss deduction cannot exceed 90 percent of AMTI.  Further,
tax-exempt interest on certain private activity bonds issued after August 7,
1986, constitutes a tax preference increasing AMTI.  Finally, the 1990 Act made
various technical changes to the AMT.

3.   Bad debt deduction.  The 1986 Act required a bank with average adjusted 
bases of all assets exceeding $500 million ("large bank") to compute its bad
debt deduction using the specific charge-off method.  Under that method, a
deduction is taken at the time the debt becomes partially or wholly worthless. 
Under prior law, a large bank could also use one of two reserve methods, under
which a bad debt deduction is computed according to the amount added to a
reserve set aside for bad debts.  The 1986 Act, as modified by the 1990 Act,
continued to permit a bank not meeting the definition of a large bank ("small
bank") to use either the specific charge-off method or the "experience" reserve
method, under which the addition to bad debt reserve is based on the bank's
actual loss experience for the current year and five preceding years.

In 1991 the I.R.S. issued proposed regulations permitting a bank to elect to
establish a conclusive presumption that a debt is worthless, based on applying
a single set of standards for both regulatory and tax accounting purposes.

1.   Interest incurred for tax-exempt obligations.  Generally, taxpayers are not
allowed to deduct interest on indebtedness incurred to purchase or carry
tax-exempt obligations.  Prior to the 1986 Act, this provision generally did
not apply to interest paid by banks or other financial institutions with
respect to debts incurred in the ordinary course of the bank's business.
Banks were subject, however, to a 20 percent disallowance of such interest in
certain cases.

The 1986 Act denies a deduction to banks for the portion of the bank's interest
that is allocable to tax-exempt obligations




                                       12
<PAGE>   16
acquired by the bank after August 7, 1986.  The 20 percent disallowance of
pre-1986 Act law continues to apply to tax-exempt obligations acquired between
January 1, 1983, and August 7, 1986.  A special exception applies to a
"qualified tax-exempt obligation," which includes any tax-exempt obligation
that (a) is not a private activity bond and (b) is issued by an issuer that
reasonably anticipates it will issue not more than $10 million of tax-exempt
obligations (other than certain private activity bonds) during the calendar
year.  Qualified tax-exempt obligations are treated as acquired before August
8, 1986; thus, interest expense allocable to such bonds continues to be
deductible, subject to the 20 percent disallowance.

5.   Net operating losses.  Under the 1986 Act, a bank is permitted to carry a 
net operating loss ("NOL") back to the prior three tax years and forward to
the succeeding fifteen tax years, as opposed to the ten-year carryback and
five-year carryforward periods of prior law.  The prior law periods were
retained, however, to the extent the NOL of a commercial bank is attributable to
a bad debt deduction taken under the specific charge-off method.  This special
rule applies to NOLs for tax years beginning after December 31, 1986, and before
January 1, 1994.  The 1990 Act clarifies that a commercial bank's bad debt loss
is treated as a separate NOL to be taken into account after the remaining
portion of the NOL for the year.

6.   California tax laws.  A commercial bank is subject to the California
franchise tax.  The applicable tax rate is higher than that applied to general
(non-financial) corporations because it includes an amount "in lieu" of many
other state and local taxes and license fees payable by such corporations but
generally not payable by banks and financial corporations.  The bank tax rate
for income years ending in 1989, 1990 and 1991 was 10.741%. Under 1991
legislation, for income years ending after 1991 and before December 1, 1995,
the rate is the franchise tax rate applicable to general corporations
(currently 9.3%) plus the in-lieu rate, but the total rate cannot exceed 11.7%.
The in-lieu rate is computed under a formula based on the amounts of personal
property taxes, business license taxes, and California income reported for
general corporations, and must be at least 1.3%. For income years ending on or
after December 31, 1995, the applicable franchise tax rate will be the general
corporate rate plus 2%, with no ceiling.

For income years beginning after 1987, California substantially adopted the
federal AMT, subject to modifications for the ACE adjustment, computation of
NOLS, tax preference treatment for tax-exempt interest, and certain other items.
Generally, a bank is subject to California AMT in an amount equal to the sum of
(a) seven percent of AMTI (computed for California purposes) over an exemption
amount and (b) the excess of the bank tax rate over the general corporation tax
rate applied against net income for the taxable year, unless the bank's regular
tax liability is greater.

California permits a bank to compute its deduction for bad debt losses under    
either the specific charge-off method or according to the amount of a reasonable
addition to a bad debt reserve.  Regulations provide detailed rules for
determining the deduction under either method.

California has incorporated the federal NOL provisions, subject to significant
modifications.  Generally, NOLs arising in income years beginning before 1987
or after January 1, 1997 are disregarded.  No carryback is permitted, and only
fifty percent of the NOL for any income year may be carried forward.  Under
1991 legislation, NOL carryover deductions have been suspended for income years
beginning in calendar years 1991 and 1992, although the carryover period of
fifteen years is extended for two years for any NOL deductions denied because
of the suspension period.

The various laws discussed herein contain other changes that could have a
significant impact on the banking industry.  The effect of these changes is
uncertain and varied, and it is unclear to what extent any of these changes may
influence the Company's operations or the banking industry generally.

Federal and state laws applicable to financial institutions have undergone
significant changes in recent years.  The most significant recent federal
legislation enactments are the Federal Deposit Insurance Corporation
Improvement Act of 1991 and the Financial Institutions Reform, Recovery, and
Enforcement Act of 1989.

Federal Deposit Insurance Corporation Improvement Act of 1991 

General

The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
was enacted on December 19, 1991 and addresses, among other things, the safety
and soundness of the deposit insurance funds, supervision of and accounting by
insured depository institutions and prompt regulatory action by the FDIC with
respect to troubled institutions.  FDICIA also places restrictions on the
activities of insured State banks and provides enhanced enforcement authority
for the FDIC and additional safeguards against insider abuse.

Prompt Regulatory Action

FDICIA amended the Federal Deposit Insurance Act ("FDIA") to establish a format
for closer monitoring of insured depository institutions and to enable prompt
corrective action by regulators when an institution begins to experience
difficulty.

FDICIA established five capital categories: (i) well capitalized;  (ii)
adequately capitalized;   (iii) undercapitalized; (iv) significantly
undercapitalized; and (v) critically undercapitalized.   Relevant capital
measures for determining the

                                      14
<PAGE>   18

placement of a depository institution within a category will include a leverage
limit, a risk-based capital requirement and other capital measures which may be
established by regulations adopted by the federal banking agencies.  The
general thrust of these provisions is to impose greater scrutiny and more
restrictions on institutions as they descend the capitalization ladder, from
well capitalized to critically undercapitalized.

All institutions are barred from making capital distributions or paying
management fees to persons having control of the institution if to do so would
leave the institution undercapitalized.

Undercapitalized institutions will be closely monitored and will be subject to
restrictions on activities and asset growth.  In addition, they will be
required to develop and submit a capital restoration plan, which must include
(i) the steps the institution will take to become adequately capitalized; (ii)
the levels of capital to be attained during each year in which the plan will be
in effect; (iii) how the institution will comply with restrictions or
requirements imposed on its activities; and (iv) the types and levels of
activities in which the institution will engage.  Generally, the capital
restoration plan must be submitted within 45 days of the institution's becoming
undercapitalized.  In addition, any company which controls a depository
institution required to submit a capital restoration plan must guarantee that
the institution will comply with the plan, provided that the liability under
such guarantee will not exceed the lesser of five percent of the institution's
total assets or the amount needed to bring the depository institution into
compliance with all applicable capital standards.

Significantly undercapitalized institutions and institutions that fail to
submit and implement capital restoration plans may be ordered to (i)
recapitalize by selling enough shares to bring the institution to an adequately
capitalized level; (ii) restrict dealings with affiliates; (iii) restrict
interest rates paid on deposits; (iv) restrict asset growth or reduce total
assets; (v) alter or eliminate any activity determined by the bank regulatory
agency to pose an excessive risk to the institution; (vi) hold a new election
for the institution's board of directors, dismiss directors or senior officers,
or both; (vii) cease accepting deposits from correspondent depository
institutions; and (viii) divest itself of subsidiaries and/or require any
company controlling the institution to divest itself of any affiliate other
than the institution and/or divest itself of the depository institution.  In
addition, significantly undercapitalized institutions will be prohibited from
paying any bonus to a senior executive officer and will be limited in
increasing compensation above specified amounts for such officers, in each case
without receiving prior agency approval.

A critically undercapitalized institution will face even more severe
restrictions.  In addition to those steps that can be taken with respect to
significantly undercapitalized institutions, prior




                                       15
<PAGE>   19

written FDIC approval would be required for many actions, such as making        
payments on subordinated debt, financing a highly leveraged transaction,
amending its by-laws, materially changing its accounting methods, or paying
excessive compensation or bonuses.  In addition, a critically undercapitalized
institution must be placed in receivership by the appropriate federal banking
agency within 90 days of becoming critically undercapitalized, unless the agency
determines, with FDIC concurrence, that other action would better achieve
statutory goals.

FDICIA also provides that if an institution is in an unsafe or unsound  
condition or is engaging in an unsafe or unsound practice, its capital category
may be downgraded to achieve a higher level of regulatory scrutiny.

In addition to the provisions described above, FDICIA requires each federal     
banking agency to adopt regulations prescribing non-capital standards for
institutions under its authority covering (i) internal controls, information
systems, and internal audit systems; (ii) loan documentation; (iii) credit
underwriting; (iv) interest rate exposure; (v) asset growth; (vi) compensation,
fees and benefits; (vii) other operational and managerial standards; and (viii)
asset quality, earnings, and stock valuation.  In the event the relevant agency
determines that an institution fails to meet any of such standards, the
institution must develop and implement a plan to correct the deficiency.

Conservatorship and Receivership

FDICIA adds additional grounds to the previously existing list of reasons for   
appointing a conservator or receiver for an insured depository institution. The
added grounds include (i) substantial dissipation of assets or earnings due to
an unsafe or unsound practice or any violation of law or regulation; (ii) the
existence of an unsafe or unsound condition; (iii) any willful violation of a
cease and desist order; (iv) any concealment of assets, records, books or papers
from any federal or state bank regulatory agency; (v) if the institution is
likely to be unable to meet obligations in the normal course of business; (vi)
losses threatening capital; (vii) becoming undercapitalized if the institution
(A) has no reasonable prospect of becoming adequately capitalized; (B) fails to
become adequately capitalized after being ordered to do so; (C) fails to timely
submit an acceptable capital restoration plan; or (D) fails to implement an
accepted restoration plan; or (viii) is critically undercapitalized or otherwise
has substantially insufficient capital.

Federal Reserve Discount Window Advances

Beginning December 19, 1993 no advances from a Federal Reserve Bank to any      
undercapitalized depository institution may be outstanding for more than 60 days
in any given 120-day period, unless the head of the appropriate federal banking
agency certifies to the Federal Reserve Bank that the institution is viable, or
if the Federal


                                       16
<PAGE>   20
Reserve Board Chairman so certifies to the Federal Reserve Bank.  In either
case, a grace period for the next 60 days may be provided.  This grace period
may be extended upon further certifications.

There are more stringent restrictions on advances to critically
undercapitalized institutions.  The window is reduced to five days and if the
FDIC incurs any losses exceeding what it would have lost in liquidation, then
the Federal Reserve Board is liable to the FDIC for that loss, subject to
certain limitations.  More importantly, Federal Reserve banks shall have no
obligation to make, increase, renew, or extend any advance or discount to any
depository institution.  The Federal Reserve Board is given the prerogative of
examining any depository institution or affiliate in connection with any
Federal Reserve System transaction.

Brokered Deposits

FDICIA continues restrictions on the acceptance of brokered deposits by insured
depository institutions that are not well capitalized.  It also places
restrictions on the interest rate payable on brokered deposits and the
solicitation of such deposits.  An undercapitalized institution will not be
allowed to solicit brokered deposits by offering rates of interest that are
significantly higher than the prevailing rates of interest on insured deposits
in the particular institution's normal market areas or in the market area in
which such deposits would otherwise be accepted.  In addition, the FDIC is
required to adopt final regulations to implement the new limitations on
brokered deposits by May 18, 1992 and those regulations are required to become
effective not later than June 16, 1992.

Risk-Based Assessment System

FDICIA amended the FDIA to require the FDIC to establish a risk-based assessment
system for depository institutions.  The risk-based assessment system would be
used to calculate a depository institution's semiannual deposit insurance
assessment based on the probability that the deposit insurance fund will incur
a loss with respect to the institution.  In determining the probability of
loss, the FDIC will take into consideration different categories and
concentrations of assets and liabilities (both insured and uninsured,
contingent and noncontingent) and any other factors that the FDIC determines
are relevant to assessing such probability.

The FDIC will set semiannual assessments for insured depository institutions to
maintain the reserve ratio of the BIF and the SAIF or if the reserve ratio is
less than the designated reserve ratio, to increase the reserve ratio to the
designated ratio.  The designated reserve ratio for the BIF and the SAIF for
each year will be 1.25 percent of estimated insured deposits.  The FDIC may set
a higher percentage if the agency determines that there is a significant risk
of substantial future loss to the particular insurance fund.  In addition, the
FDIC will set the semiannual


                                       17
<PAGE>   21

assessments for BIF independently from the semiannual assessments for SAIF.

Also, if the reserve ratio for either deposit insurance fund is less than the
designated reserve ratio, the FDIC will set semiannual assessment rates for
each BIF or SAIF member that are sufficient to increase the reserve ratio for
the particular fund not later than one year after the assessment rates are set
or in accordance with a schedule promulgated by the FDIC.  That
recapitalization schedule will specify, at semiannual intervals, target reserve
ratios for the particular deposit insurance fund, culminating in a reserve
ratio that is equal to the designated reserve ratio not later than 15 years
after the date on which the FDIC implements the schedule.

In setting the assessments for each deposit insurance fund, the FDIC will
consider the fund's expected operating expenses; case resolution expenditures
and income; the effect of assessments on members' earnings and capital; and
other factors that the FDIC may deem appropriate.  Until a deposit insurance
fund achieves its designated reserve ratio, the FDIC may limit the maximum
assessment on insured depository institutions under the risk-based assessment
system to not less than 10 basis points above the average assessment on insured
institutions under that system.

Certified Assessment Statements

Generally, each insured depository institution will file with the FDIC a
certified statement containing information as required by the FDIC for
determining the institution's semiannual assessment.  The form of the
certification will also contain supporting information as required by the FDIC
and is to be certified by the president of the depository institution or any
other designated officer.

FDICIA established a three-tier penalty system for failure to make accurate
certified statements.  Any insured depository institution which maintains
procedures reasonably adapted to avoid any inadvertent error and,
unintentionally as a result of such an error, fails to submit a certified
statement or submits a false or misleading certified statement or inadvertently
transmits a report that is minimally late will be subject to a penalty of not
more than $2,000 for each day a violation continues or the false or misleading
information is not corrected.  The burden of proving that an error was
inadvertent or that a report was inadvertently submitted late will be on the
institution.

A second tier penalty will be assessed against any insured depository
institution which fails to submit a certified statement within the required
time period or submits a false or misleading certified statement, without the
mitigating circumstances described above.  The penalty for a second tier
offense will be up to $20,000 for each day a violation continues or the false
or misleading information is not corrected.


                                       18
<PAGE>   22

Finally, if any insured depository institution knowingly or with reckless
disregard for the accuracy of any information contained in a certified
statement submits any false or misleading certified statement, the FDIC may
assess a penalty of as much as $100,000,000 or 1 percent of total assets,
whichever is less, per day for each day during which such failure continues or
the false and misleading information is not corrected.

Insider Abuse

FDICIA also strengthens remedies for insider abuse by recodifying current law
restricting extensions of credit to insiders under the Federal Reserve Act.
The FRA places limitations and conditions on extensions of credit by member
banks to their executive officers, directors, or principal shareholders, or to
any related interest of such a person.  FDICIA extends the scope of these
provisions to include state nonmember banks in addition to member banks.

Other restrictions placed on extensions of credit by banks to insiders under
FDICIA include a provision that requires banks to follow credit underwriting
procedures that are not less stringent than those applicable to persons who are
not insiders.  Also, the aggregate limits on extensions of credit to all
insiders cannot exceed a member bank's unimpaired capital and unimpaired
surplus.  An exception to this limitation is provided if a bank has less than
$100,000,000 in deposits and the FRB determines that the exception is important
to avoid constricting the availability of credit in small communities or to
attract directors to such banks.

Annual Examinations and Reports

Annual full-scope, on-site examinations will be required of all insured
depository institutions.  The appropriate federal banking agency will conduct
the examinations, unless the FDIC has conducted one in the given 12-month
period.  The federal agency exams may be staggered every two years for
institutions in which a state banking agency conducts exams in the intervening
year.  For small, well-capitalized institutions that are well managed and in
outstanding condition, and whose ownership has not changed in the preceding
year, the exams by the federal banking agencies may be at 18-month intervals.
Examinations are to begin for the period starting December 19, 1992.  During
the transition period lasting until December 31, 1993, the general rule will be
for 18-month intervals between exams, unless the institution is in less than
satisfactory condition or there is new ownership.

For fiscal years beginning after December 31, 1992, each insured depository
institution will be required to submit a publicly-available annual report to the
appropriate federal banking agency, state bank supervisor and to the FDIC.  In
addition, each institution will be required to prepare an annual financial
statement using generally accepted accounting principles,
                                       
                                      19
<PAGE>   23
fulfilling any additional disclosure requirements imposed by the federal
banking agencies.

An independent public accountant will be required to "attest to" management's
report prepared pursuant to these new requirements.  The independent accountant
will also monitor management's compliance with governing laws and regulations.
Each institution will also be required to select an independent audit committee
made up of outside directors who are independent of management to review with
management and the independent accountant the required reports.  If an auditor
resigns or is dismissed, written notification must be provided to the
appropriate federal banking agency.(1/)

Financial Institutions Reform, Recovery, and Enforcement Act of 1989

The Financial Institutions Reform, Recovery, and Enforcement Act of 1989
("FIRREA") was enacted on August 9, 1989.  Among the many major changes made by
this law is a measure requiring the FDIC to assume responsibility for insuring
the deposits of financial institutions formerly insured by the Federal Savings
and Loan Insurance Corporation.  FIRREA established two separate insurance
funds to be administered by the FDIC.

FIRREA also strengthened the FDIC'S regulatory enforcement authority in the
following ways: (i) it expanded the categories of persons over whom enforcement
powers may be exercised, (ii) it reduced the threshold for the imposition of
civil monetary penalties, including allowing such penalties to be imposed for
an inadvertent failure to file a regulatory report in a timely fashion, (iii)
it substantially increased criminal and civil monetary penalties, (iv) it added
remedies, including "reimbursement" by parties committing a wrong and orders
requiring the sale of assets, (v) it enhanced provisions for immediate
remedies, (vi) it expanded the FDIC's powers to appoint conservators and
receivers, and (vii) it allows the FDIC to proceed against "commonly controlled
insured financial institutions" in the event that the FDIC is required to
provide assistance to a troubled "sister" financial institution.

FIRREA also provides that banks which (i) have been chartered less than two
years; (ii) have undergone a change of control within the preceding two years;
(iii) are not in compliance with minimum capital requirements; or (iv) have
been determined by the appropriate banking agency to be in a troubled
condition, are required to notify the appropriate banking agency of the
proposed

- ------------
(1/) These requirements will not apply to any insured depository institution 
with respect to any fiscal year if, at the beginning of such fiscal year, the
institution had total assets of less than (i) $150,000,000; or (ii) such higher
amount as the FDIC prescribes by regulation.


                                       20
<PAGE>   24

addition of any individual to the board of directors or the employment of any   
individual as a senior executive officer, at least thirty days before such
action becomes effective.  The appropriate banking agency is then empowered to
disapprove any such addition or employment.

FIRREA prohibits a bank from entering into a written or an oral contract with   
any person to provide goods, products, or services to or for the benefit of the
bank which would jeopardize the safety or soundness of the bank.  In addition,
FIRREA prohibits a bank which does not meet the minimum capital requirements
applicable to it from accepting brokered deposits.  As noted above, FDICIA has
continued and increased restrictions on brokered deposits.

Finally, FIRREA requires banks to provide copies of reports of condition,       
reports of examination and memoranda of understanding and other regulatory
orders, if any, to their independent auditors.

State Legislation

The California Interstate (Regional) Banking Act of 1986 (the "Regional Act")   
was enacted, effective July 1, 1987, to permit an out-of-state bank holding
company to acquire banks in California if the holding company conducted its
principal operations in Alaska, Arizona, Colorado, Hawaii, Idaho, Nevada, New
Mexico, Oregon, Utah, Texas, or Washington.  Generally, such acquisitions were
subject to the approval of the Federal Reserve Board and the California
Superintendent of Banks and to the existence of reciprocal interstate
legislation in the state in which the operations of the bank holding company
were conducted.  The Regional Act was repealed by its terms on January 1, 1991
and was replaced, effective that date, by the California Interstate (National)
Banking Act of 1986, which extended the interstate banking authorization on a
nation-wide basis, subject to the continuing requirement of substantial
reciprocity between California and the state in which the operations of the bank
holding company are principally conducted.

Other legislation has been or may be proposed to the United States Congress     
and the California Legislature and regulations may be proposed by the Federal
Reserve Board, the Comptroller and the FDIC which could affect the business of
the Bank.  Management of the Bank cannot predict whether such pending or
proposed legislation or regulations will be adopted and cannot predict the
effect such proposed legislation or regulations may have on its business.

Holders

The Bank has authorized 3,000,000 shares of Common Stock, par value $2.50 per
share.  As of March 18, 1991, 1,297,224 shares were outstanding and were held
by approximately 525 shareholders of record.

Dividends

On January 24, 1991, the Board of Directors declared a dividend of forty five
cents per share to shareholders of record February 4, 1991.  On July 18, 1991,
the Board declared a dividend of fifty five cents per share to shareholders of
record July 30, 1991.  On January 23, 1992, the Board declared a dividend of
fifty five cents per share to shareholders of record February 3, 1992.

Currently there are no existing contractual restrictions on the Bank's ability

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

Capital

During 1991, the Bank's capital net of dividends paid increased by $2,794,593
or 12.48%, compared to an increase of $2,925,612 or 15.03% in 1990, an increase
of $3,168,971 or 19.44% in 1989.  Sources of additional capital in each of the
periods were retained earnings, exercise of stock options and purchases of new
stock by the Bank's profit sharing plan.  The Consolidated Statement of Changes
in Shareholders' Equity in the financial statements reflects the detailed
changes.

It is the intention of the Bank to continue capital augmentation through
earnings retention net of dividends in future years.

Liquidity

Historically, the Bank's balance sheet has shown a high degree of liquidity.
The following table shows balance sheet proportions for the years ending
December 31, 1991, December 31, 1990 and December 31, 1989:

Bank assets containing a high degree of liquidity are Cash & Due from Banks,
Investment Securities and Federal Funds sold.  In 1991, those assets comprised
35.86% of the Bank's assets compared to 36.01% in 1990 and 37.11% in 1989.

A principal source of liquidity is new deposit generation.  Until 1987, loan
generation had lagged deposit growth.  In 1991, loan growth was equal to
deposit growth.  In the following table, loans include bankers' acceptances.
Growth rates for the last three years are shown in the following table:

</TABLE>

The investment portfolio is another source of liquidity.  While a portion of
the portfolio is intended to be a long term investment, a portion is invested
in short-term obligations pending re-employment of these funds in the loan
portfolio or for deposit withdrawals.  As of December 31, 1991, bonds totaling
$12,686,000 mature within one year.  Additionally, at December 31, 1991, the
Bank owned bankers' acceptances totaling $15,114,693 which mature within 180
days.  The securities in the portfolio are freely marketable.

Other internal sources of liquidity are the retention of earnings and cash flow
generated in the loan portfolio.

External sources of liquidity include borrowings available to the Bank.  As of
December 31, 1991, the Bank has two lines of credit available totaling
$8,000,000 of which $3,000,000 is on an "as available" basis.  An additional
$5,000,000 is committed to June 30, 1992, and on which commitment fees have
been paid.

Results of Operations

Average deposits and other borrowings increased $51.5 million or 20.11% from
December 31, 1990 to December 31, 1991 compared to an increase of $40.3 million
or 19.22% from December 31, 1989 to December 31, 1990.  The increase was in all
deposit categories except time deposits with the largest part of the increase
in money fund deposits, 38.03%.  Time deposits decreased $12.7 million, or
26.90%.  In the same period, average loans, net of bankers' acceptances,
increased by $26.2 million, or 16.25%.  The loan to deposit ratio decreased to
64.21% on an average balance basis for the period ending December 31, 1991 from
64.37% for the period ending December 31, 1990.  On an average basis, the
investment portfolio increased by $7.2 million, or 12.38%, to $66.2 million in
1991.  Federal funds sold and bankers'

acceptances were used as alternative short-term investment vehicles.

Total average assets increased by 13.06%, or $35.7 million, to $309 million for
the year ending December 31, 1991.  This compares to a growth rate of 19.04% in
1990, 5.78% in 1989, 23.23% in 1988, 37.0% in 1987, 26.0% in 1986, 31.7% in
1985 and 31.2% in 1984.  Total assets at December 31, 1991 were $337 million,
an increase of 17.36% over 1990.

Daily average balances are expressed in thousands of dollars.

In the Bank's eleventh full year of operations, net income totaled $3,216,151
compared to $3,365,096 in 1990, and $3,245,783 in 1989.  Comparable per
weighted share earnings were $2.46, $2.61, $2.56, and $2.42 December 31, 1991,
1990, and 1989 respectively.  Book values per common share were $19.74, $18.30,
and $16.29 for the respective periods.  Per share amounts have been restated to

The primary source of the Bank's earnings is net interest income which
represents the difference between interest earned on loans and investments and
interest paid on deposits and short-term borrowings.  In 1991, net interest
income on a taxable equivalent basis was $14,383,000, an increase of 6.88% over
the $13,457,000 reported in 1990.  This compares to a 8.62% increase over the
$12,389,000 reported in 1989.

Net interest margin decreased by twenty-nine basis points to 5.21% for the year
ending December 31, 1991.  Net interest margin was 5.50% in 1990 and 6.04% in
1989.

A more detailed discussion of the components of income and expense follows and

In the following Analysis of Changes in Interest Income and Expense, the change
resulting from growth is expressed as a volume change while the change in yield
is expressed as a rate change.  Income and yields are on a fully taxable
equivalent basis, using the federal statutory income tax rate of 34% in 1991
and 1990.

Interest Rates and Interest Differentials

The primary source of the Bank's earnings is the net interest income, or
interest differential, which represents the difference between interest earned
on loans and investments and interest paid on deposits and short term
borrowings.  In 1991, net interest income on a taxable equivalent basis was
$14,383,000, an increase of 6.88% over the $13,457,000 net interest income in
1990.  This compares to a 8.62% increase in 1990 over net interest income of
$12,389,000 in 1989.

Net interest margin, interest paid as a percent of average earning assets,
decreased twenty-nine basis points from 5.50% in 1990 to 5.21% in 1991.

Interest income on a taxable equivalent basis decreased from $26,956,000 in
1990 to $26,583,000 in 1991, which represents a 1.38% decrease.  Interest
income in 1990 had increased 13.79% over interest income in 1989, which was
$23,689,000.  The decrease in 1991 was attributable to a decrease in yield from
11.03% to 9.63%.  The increase in 1990 was attributable to a 21.39% increase in
average loans.  Overall, average rates earned on total earning assets decreased
by one hundred forty basis points.  A principal factor in this decrease was the
decrease in the average daily prime rate from 10.01% to 8.46% in 1991.
Interest expense on deposits and borrowed money decreased by $1,299,000, or
9.62% in 1991, as compared to an increase of $2,199,000, or 19.46%, in 1990.
Average balances of interest-

<PAGE>   35
bearing liabilities increased by 12.94% in 1991, as compared to a
19.22% increase in 1990.  The average rate paid on interest bearing liabilities
decreased by one hundred eight basis points from 5.40% in 1990 to 4.32% in
1991.  In 1989, the average rate paid on interest-bearing liabilities was
5.39%.

Demand deposits increased $4,033,000, or 12.93% in 1991 compared to an increase
of $3,824,000 or 13.97% in 1990 over 1989.  The Bank's demand deposits are held
primarily by corporate depositors doing business with the Bank.

Loss Provision and Allowance for Possible Loan Losses

The Bank provided $875,000 as an addition to the allowance for possible loan
losses in 1991.  In 1990, the provision was $360,000.  At December 31, 1991,
the allowance for loan losses was $1,828,025 or .94% of eligible loans, net of
bankers' acceptances, compared with $1,724,021, or 1.05% of eligible loans at
December 31, 1990.  Net losses in 1991 were $770,996, compared to net losses of
$425,762 in 1990.

Trust and fiduciary fees accounted for 61.80% of non-interest revenues in 1991
compared to 57.23% in 1990 and increased $274,000 or 21.37% in 1991.  The
market value of trust assets,


                                      32
<PAGE>   36
upon which those fees are based, increased by $189 million, or 69.63%, to $460
million at December 31, 1991.  The increase of trust assets accounted for the
increase in fee income. Service charges on deposit accounts increased 15.78% to
$477,000.  The increase in service charge income is due to the increased number
of deposit accounts.  Other income is derived primarily from safe deposit
rentals, traveler's cheque commissions and miscellaneous fees for other bank
services.  Other income decreased by 11.17% to $485,000 in 1991.  The decrease
in 1991 is partially attributed to the sale of a lease for $119,000 and the
collection of residuals on leveraged leases of $63,000 which were non-
recurring events in 1990.

</TABLE>

Non-interest expense increased $823,000 or 8.67% in 1991 over 1990.  This
compares to a 18.06% increase in 1990.

Salaries and employee benefits increased 10.15% over 1990 compared to a 20.09%
increase in 1990 over 1989.  The increases were due to pay increases and to
staff increases that were necessary to service the substantial increases in
deposits and earning assets.  Average full-time equivalent staff in 1991 was
112.5 compared to 107.5 in 1990, an increase of 4.65%.  Occupancy expense
decreased $46,000, or 4.54%, in 1991, compared to a increase of 45.48% in 1990.
The increase in 1990 was the result of leasing the building at 800 Oak Grove,
Menlo Park and the decrease in 1991 was the result of owning it.  Marketing
expense decreased by 22.09% in 1991 over 1990 compared to an increase of 9.40%
in 1990.  The category of non-interest expense which increased by the largest
percentage was FDIC and OCC assessments which increased $280,000 or 84.08% in
1991 over 1990 compared to an increase of $110,000, or 49.33% in 1990 over
1989.  Increases


                                      33
<PAGE>   37
in all categories of other expense are attributed primarily to the Bank's
growth in 1991 and 1990 and the opening of the new facilities in Menlo Park and
Santa Cruz in late 1989.

Loan Portfolio

The Bank's loan portfolio is primarily composed of commercial and industrial
loans with adjustable or floating interest rates.  Adjustable rate loans
comprise approximately 97% of the portfolio, a factor that is critical to
maintaining a favorable spread between yields on earning assets and rates paid
on interest-bearing liabilities.

Investment Portfolio

The Bank's investment portfolio increased by $10,075,000 or 15.85% to
$73,653,000 at December 31, 1991.  This compares to an increase of $7,176,000
in 1990.  The increase in both 1991 and 1990 was caused by the high degree of
liquidity afforded by deposit inflows.  The principal increases were in
investments in U.S. Agency obligations which increased $6,619,000, or 22.67%
and municipal obligations which increased $5,023,000 or 15.50%.  At December
31, 1991, the investment portfolio contained $3,974,422 net unrealized
appreciation compared to $1,699,816 in net unrealized depreciation at December
31, 1990.  The following table breaks down the Bank's investment portfolio by
type, maturity and yield at December 31, 1991 and 1990.

                         Independent Auditors' Report


The Board of Directors
University National Bank & Trust Company:


We have audited the accompanying consolidated balance sheets of University
National Bank & Trust Company and subsidiary as of December 31, 1991 and 1990,
and the related consolidated statements of income, changes in shareholders'
equity and cash flows for each of the years in the three-year period ended
December 31, 1991.  These consolidated financial statements are the
responsibility of the Bank's management.  Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of University National
Bank & Trust Company and subsidiary as of December 31, 1991 and 1990, and the
results of their operations and cash flows for each of the years in the
three-year period ended December 31, 1991, in conformity with generally
accepted accounting principles.

                   Notes to Consolidated Financial Statements

                        December 31, 1991, 1990 and 1989

(1) Summary of Significant Accounting Policies

(a) General

University National Bank & Trust Company commenced business as a commercial
bank on May 13, 1980.  University National Bank & Trust Company's main facility
is located in downtown Palo Alto, with an additional banking floor in downtown
Menlo Park.  The commercial banking services offered include accepting
checking, savings and time deposits and money fund deposit accounts.
University National Bank & Trust Company makes commercial and installment loans
and certain real estate loans and offers safe deposit services and other
customary banking services to the retail, business and professional community
in and adjacent to Palo Alto.  In addition, University National Bank & Trust
Company offers trust services, including serving as trustee under employee
benefit plans, living trusts and testamentary trusts.  In addition to their
banking facilities, a trust representative office is located in Santa Cruz.

(b) Principles of Consolidation

The consolidated financial statements include the accounts of University
National Bank & Trust Company and its subsidiary (collectively the "Bank"). All
intercompany transactions have been eliminated.

(c) Investment Securities

Investment securities are those securities which management intends to hold to
maturity based on currently foreseeable conditions.  These securities are
stated at cost adjusted for amortization of premiums and accretion of
discounts, using methods approximating the interest method.  Gains or losses on
disposition are based on the net proceeds and adjusted carrying amount of the
securities sold, using the specific identification method.




                                                                     (Continued)

                   Notes to Consolidated Financial Statements

(d) Loans and Allowance for Loan Losses

Loans are stated at the amount of unpaid principal net of undisbursed funds,
reduced by an allowance for loan losses.  Interest on commercial, consumer
installment and real estate loans is accrued on a simple interest method on
daily balances of the principal amount outstanding.  The allowance for loan
losses is established through a provision for loan losses charged to expense.
Loans are charged against the allowance for loan losses when management
believes that the collectibility of the principal is unlikely.  The allowance
is an amount that management believes will be adequate to absorb possible
losses on existing loans that may become uncollectible, based on evaluations of
the collectibility of loans and prior loan loss experience.  The evaluations
take into consideration such factors as changes in the nature and volume of the
loan portfolio, overall portfolio quality, review of specific problem loans and
current economic conditions that may affect the borrowers' ability to pay.
Accrual of interest is discontinued and prior accrued interest is reversed on a
loan when the payment of interest or principal is 90 or more days past due.

Loan origination and commitment fees and certain direct loan origination costs
are deferred and the net amount amortized as an adjustment of the related
loan's yield.

(e) Buildings, Furniture and Equipment

Buildings, furniture 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.

(f) Income Taxes

The Bank currently recognizes income tax expense based upon the deferred
method.  Under this method, deferred income taxes are provided for timing
differences between items of income or expense reported in the consolidated
financial statements and those reported for income tax purposes.  The
differences relate principally to depreciation of equipment, provision for loan
losses, the method of recognizing income from leases and the use of the accrual
basis of accounting for financial statement purposes and the cash basis of
accounting for income tax purposes in past years.




                                                                     (Continued)

                    UNIVERSITY NATIONAL BANK & TRUST COMPANY

                   Notes to Consolidated Financial Statements

Statement of Financial Accounting Standards No. 96, "Accounting for Income
Taxes," (SFAS 96) was issued by the Financial Accounting Standards Board in
December 1987.  SFAS 96 requires a change from the deferred method to the asset
and liability method of accounting for income taxes.  Under the asset and
liability method, deferred income taxes are recognized for the tax consequences
of "temporary differences" by applying enacted statutory tax rates applicable
to future years to differences between the financial statement carrying amounts
and the tax bases of existing assets and liabilities.  Under SFAS 96, the
effect on deferred taxes of a change in tax rates is recognized in income in
the period that includes the enactment date.

SFAS 96 was amended by SFAS 108 which deferred the effective date to fiscal
years beginning after December 15, 1992.  Upon adoption, the provisions of SFAS
96 may be applied without restating prior years' financial statements or may be
applied retroactively by restating any number of consecutive prior years'
financial statements.

The Bank estimates that the eventual adoption of the provisions of SFAS 96 will
not have a material impact on the financial statements.

(g) Net Income Per Common Share

Primary net income per common share of $2.46 in 1991 is based on the weighted
average number of common shares outstanding, including the effect of stock
options.  The net income per common share for 1991 includes net shares issuable
upon assumed exercise of stock options using the "treasury stock method," which
assumes that the stock options are exercised at the beginning of the year and
the proceeds from the exercise are used to purchase common stock at average
market prices.

(h) 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 for less than 90-day
periods.

Supplemental disclosures of cash flow information follow:

       Management believes that the allowance for loan losses is adequate.
       While management uses available information to recognize losses on
       loans, future additions to the allowance may be necessary based on
       changes in economic conditions.  In addition, various regulatory
       agencies, as an integral part of their examination process, periodically
       review the Bank's allowance for losses on loans.  Such agencies may
       require the Bank to recognize additions to the allowance based on their
       judgments of information available to them at the time of their
       examination.

                   Notes to Consolidated Financial Statements

       Certain directors, executive officers and principal holders of equity
       securities are loan customers of the Bank.  Such loans are made in the
       ordinary course of business on normal credit terms, including interest
       rate and collateralization, and none represent more than a normal risk
       of collection.  Such loans were approximately $2,170,000 and $1,620,000
       at December 31, 1991 and 1990, respectively.  During 1991, additional
       loans of approximately $1,504,000 were made and payments of
       approximately $954,000 were received.

       On February 1, 1991, the Bank purchased the Menlo Park building which
       was previously leased.  The bank leases its Santa Cruz trust office
       under an operating lease.  The office lease has a noncancelable lease
       term which expires in October 1992.  Upon expiration of the lease, the
       Bank has the option of extending the term on a month-to-month basis,
       and shall pay a monthly rent equal to 125% of the monthly rent payable
       during the last month of the term.  Monthly rent is currently based on a
       minimum rental plus an adjustment for the cost of living.

       holders of record as of November 14, 1989.  In the consolidated
       financial statements and the accompanying notes, the per common share
       amounts, average number of common shares outstanding, shares reserved
       for issuance and stock option data for 1989 have been adjusted to

(7)    Employee Stock Option Plan

       The Bank has a stock option plan for certain of its officers and key
       employees.  Options have been granted at prices of $6.1875 to $32.50 a
       share.  Options are granted at prices per share not less than market
       price at date of grant.  The options are exercisable one year from the
       date of grant at 20% annually and expire at various dates through July
       17, 2001.  Options which terminate without being exercised may be
       reissued.  Shares of common stock reserved for granting of stock options
       were 9,950 and 33,550 at December 31, 1991 and 1990, respectively.

(9)    Commitments and Contingent Liabilities

       (a) Financial Instruments with Off-Balance Sheet Risk

       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.  Those instruments involve, to
       varying degrees, elements of credit, interest rate, and exchange rate
       risk in excess of the amounts recognized in the consolidated balance
       sheets.  The contractual amounts of those instruments reflect the extent
       of involvement the Bank has in particular classes of financial
       instruments.

       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.  The Bank uses the same credit policies in making
       commitments and conditional obligations as it does for on-balance sheet
       instruments.  The Bank controls the credit risk of these transactions
       through credit approvals, limits, and monitoring procedures.

       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.  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 marketable securities, accounts receivable, inventory, property,
       plant, and equipment, income-producing commercial properties and
       residential properties.

       Standby letters of credit are written 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.  Guarantees extend for less than five years and
       expire in decreasing amounts through 1996.  The credit risk involved in
       issuing letters of credit is essentially the same as that involved in
       extending loan facilities to customers.

       Of these commitments outstanding at December 31, 1991, 51% of all
       letters of credit were unsecured, while 49% of all letters of credit
       were 100% collateralized.

                                                                     (Continued)

                    UNIVERSITY NATIONAL BANK & TRUST COMPANY

                   Notes to Consolidated Financial Statements

The Bank has commitments to extend credit of $80,410,239 and $74,489,857 as of
December 31, 1991 and 1990, respectively.  The Bank also has standby letters of
credit and financial guarantees of $8,047,791 and $7,075,143 as of December 31,
1991 and 1990, respectively.  Based on the historical experience of the Bank,
management does not believe that it will be called upon to disburse all funds
under these commitments.

(b) Concentration of Credit Risk

The Bank grants residential, commercial and consumer loans to customers located
primarily in the northern California Bay Area.  Although the Bank has a
diversified portfolio, a substantial portion of its debtors' ability to honor
their contracts is dependent upon the economic sector of northern California,
including the real estate markets of the northern California Bay Area.

(c)    Available Lines of Credit

At December 31, 1991, the Bank had available an unused line of credit of
$3,000,000 for Federal fund borrowings on an "as available" basis, and a
$5,000,000 committed line of credit.  Any amounts drawn on the committed line
of credit will be collateralized by marketable securities having an aggregate
market value of not less than 125% of the loan amount.

(10) Trust Assets

The trust department of the Bank held the following types of fiduciary assets,
at cost:

The market value of the trust assets was approximately $460,583,000 and
$271,520,000 at December 31, 1991 and 1990, respectively.  These assets are not
beneficially owned by the Bank and, therefore, they are not included in the
balance sheets.

(11)     Regulatory Matters

         The Bank is subject to the Office of the Comptroller of the Currency
         (OCC) governing capital adequacy.  In 1989, the OCC adopted
         regulations for determining capital adequacy which involves assigning
         assets to four broad risk categories and establishing minimum capital
         ratios based on these assignments.  The regulations, to be phased in
         over three years, require a ratio of capital to risk-weighted assets
         of 7.25% by December 31, 1990, and 8.00% by December 31, 1992.  By
         December 31, 1992, the Bank is also required to have a minimum Tier 1
         (as defined by the regulations) ratio of 4.00%. Based on the Bank's
         capital position at December 31, 1991, management of the Bank does not
         anticipate that the implementation of these regulations will have any
         impact on the Bank's capital plans in the near term.  The Bank's
         actual ratios as of December 31, 1991 were 10.68% for total Tier 1
         capital and 11.46% for total capital to risk-weighted assets.  The
         Bank's primary capital ratio at December 31, 1991 was 8.71%.

         Additionally, banking regulations limit the amount of dividends that
         may be paid without prior approval of the Bank's regulatory agency.
         Retained earnings against which dividends may be paid without prior
         approval of the OCC amounted to approximately $7,298,000 at December
         31, 1991, subject to the minimum capital ratio requirements noted
         above.

Stock Option Plan

In 1980, the Bank adopted the University National Bank & Trust Company 1980
Stock Option Plan (the "Option Plan"), which set aside 42,000 (pre- split)
shares of the Common Stock for options which may be granted to key, full-time
salaried officers and employees of the Bank.  Non-employee Directors of the
Bank may not be granted options under the Option Plan.  The Option Plan was
amended in 1982 with the approval of the Bank's shareholders to permit the Bank
to grant incentive stock options (as defined in the Internal Revenue Code) as
well as nonqualified stock options.  The Option Plan was amended in 1984, in
1986, and in 1988 with the approval of the Bank's shareholders to increase the
number of shares reserved under the Option Plan to a total of 130,160
(pre-split) shares.  As a result of the two-for-one stock split approved by the
Bank's shareholders on November 14, 1989, the share reserve doubled to 260,160
shares.  The Option Plan was amended in 1990 with the approval of the Bank's
shareholders to increase the number of shares reserved under the Option Plan to
280,320.

In January 1987, in accordance with the terms of the Option Plan, the Board of
Directors made minor amendments to the Option Plan to incorporate changes
required by the Tax Reform Act of 1986 for incentive stock options.  Such
amendments are reflected in the following discussion of the Option Plan.

As of March 18, 1992, options to purchase 286,088 shares have been granted
under the Option Plan, grants for 36,915 shares expired unexercised, options to
purchase 96,173 shares have been exercised.  There are currently options
outstanding to purchase 153,000 shares, at option prices ranging from $7.50 to
$32.50 per share and which will expire at various times from 1992 through 2002.
Accordingly, 950 shares remain available for grant pursuant to the Option Plan.

The exercise price of all options granted under the Option Plan must be not
less than the fair market value of the Bank's Common Stock on the date the
option is granted; provided, however, the option price for any employee (a "Ten
Percent Owner Employee") owning stock possessing ten percent (10%) or more of
the total combined voting power of all stock of the Bank must be one hundred
ten percent (110%) of the fair market value of the shares on the grant date.
The fair market value of the stock for which an employee may be granted
incentive stock options for any calendar year beginning after January 1, 1987
may not become exercisable at a rate faster than $100,000 per year based on the
stock's value measured as of the grant date.  

                                      61
<PAGE>   65
Unless otherwise provided by the Bank's Board of Directors, all options
granted under the Option Plan are exercisable in five equal annual installments,
commencing one year after the date the option is granted.  An option may not
have a term exceeding ten (10) years; provided any option granted to a Ten
Percent Owner Employee may not have a term exceeding five (5) years.

In the event an employee's employment with the Bank is terminated for any
reason other than death, disability or cause, the employee's option will remain
exercisable (to the extent exercisable at the time of such termination) for a
period of thirty (30) days from the date of such termination.  In the event the
employee's employment is terminated for cause, the option will immediately
expire upon notice of such termination.  In the event the employee's employment
is terminated by the employee's death or disability, the option will remain
exercisable (to the extent exercisable immediately prior to such death or
disability) for a period of one year from the date of such termination.

Options granted are subject to the "sequential exercise rule" which means that
these options must be exercised in the sequences in which they are granted, and
that an employee must completely exercise a prior option before exercising a
subsequent option.  Compliance with the sequential exercise rule is not
required for federal or California income tax purposes for options granted
after January 1, 1987.  However, the management of the Bank has determined that
compliance with the sequential exercise rule is in the best interests of the
Bank and will be required as a condition to the exercise of an option.

In the event of a merger or consolidation in which the Bank is not the
surviving corporation or the sale of substantially all of the Bank's assets,
all outstanding options under the Option Plan become immediately exercisable.

The Option Plan provides for adjustment in the number of shares of Common Stock
authorized under the Option Plan or granted to an optionee to protect against
dilution in the event of certain changes in the Bank's capitalization,
including stock splits and stock dividends.

The Board of Directors may amend or terminate the Option Plan at any time and
may vary the terms of options to be granted in the future without the approval
of the shareholders, except that the Board may not increase the maximum number
of shares for which options may be granted in the aggregate or individually
under the Option Plan, change the formula setting the minimum price at which
options may be granted or exercised, or amend the requirements as to the class
of employees or officers eligible to receive options without the approval of
the Bank's shareholders.

The following summary is intended only as a general guide as to the federal
income tax consequences under current law respecting participation in the
Option Plan, and does not attempt to 

                                      62
<PAGE>   66
describe all possible federal or potential state and local or other tax
consequences of such participation.  Furthermore, the tax consequences of
options are complex and subject to change, and a taxpayer's particular situation
may be such that some variation of the described rules is applicable.  For
example, special tax rules apply to affiliates of the Bank.

Optionees should consult their own tax advisors prior to the exercise of any
option and prior to the disposition of any shares of Common Stock acquired upon
the exercise of an Option.

Options designated as incentive stock options are intended to fall within the
requirements of the provisions of section 422A of the Internal Revenue Code of
1986, as amended.  An optionee recognizes no taxable income as the result of
the grant or exercise of such an option.

For optionees who do not dispose of their shares for two years following the
date the option was granted nor within one year following the transfer of the
shares upon exercise of the option, the gain on sale of the shares (which is
defined to be the difference between the sale price and the purchase price of
the shares) will be taxed as long-term capital gain.  (Under present law,
however, capital gains are taxed at the same rate as ordinary income.)  If an
optionee is entitled to long-term capital gain treatment upon a sale of the
stock, the Bank will not be entitled to any deduction for federal income tax
purposes.  If an optionee disposes of shares within two years after the date of
grant or within one year from the date of exercise (a "disqualifying
disposition"), the difference between the option price and the fair market
value of the shares on the date of exercise (not to exceed the gain realized on
the sale if the disposition is a transaction with respect to which a loss, if
sustained, would be recognized) will be taxed at ordinary income rates at the
time of disposition.  Any gain in excess of that amount will be a capital gain.
If a loss is recognized, there will be no ordinary income, and such loss will
be a capital loss.  A capital gain or loss will be long-term if the optionee's
holding period is more than twelve months.  Any ordinary income recognized by
the optionee upon the disposition of stock should be deductible by the Bank for
federal income tax purposes.

The difference between the exercise price and the fair market value of the
shares on the determination date of an incentive stock option (which is
generally the date of exercise) is an adjustment in computing the optionee's
alternative minimum taxable income and may be subject to an alternative minimum
tax which is paid if such tax exceeds the regular tax for the year.  Special
rules may apply with respect to certain subsequent sales of the shares in a
disqualifying disposition, certain basis adjustments for purposes of computing
the alternative minimum taxable income on a subsequent sale of the shares, and
certain 

                                      63
<PAGE>   67
tax credits which may arise with respect to optionees subject to the
alternative minimum tax in years beginning on or after January 1, 1987.

Nonqualified stock options have no special tax status.  An optionee generally
recognizes no taxable income as the result of the grant of such an option.
Upon exercise of an option, the optionee normally recognizes ordinary income in
the amount of the difference between the option price and the fair market value
on the determination date (which is generally the date of exercise).  If the
Optionee is an employee, such ordinary income generally is subject to
withholding of income and employment taxes.  Upon the sale of stock acquired by
the exercise of a nonqualified stock option, any gain or loss, based on the
difference between the sale price and the fair market value on the date of
recognition of income, will be taxed as a capital gain or loss.  A capital gain
or loss will be long-term if the optionee's holding period is more than twelve
months from the date of recognition of income.  No tax deduction is available
to the Bank with respect to the grant of the option or the sale of the stock
acquired pursuant to such grant.  The Bank should be entitled to a deduction
equal to the amount of ordinary income recognized by the optionee as a result
of the exercise of the option.

The following table sets forth certain information as to each of the current
Executive Officers of the Bank, as to all current Directors and Executive
Officers as a group and as to all other current (non-executive) officers of the
Bank with regard to (i) options granted under the Option Plan since its
adoption and (ii) shares held subject to unexercised options as of March 18,
1992.

Profit Sharing Plan

Effective as of January 1, 1981, the Bank adopted the Employees' Profit Sharing
Plan (the "Profit Plan"), which was most recently amended and restated in its
entirety effective January 1, 1988, as the University National Bank & Trust
Company Employees' Profit Sharing and Tax Deferred Savings Plan (as so amended,
the "Profit Plan").  A First Amendment to the Profit Plan was adopted by the
Bank on June 26, 1989.

Each employee of the Bank becomes eligible to participate in the Profit Plan
beginning January 1 following his date of hire.  Each eligible employee is
permitted to contribute a specified percentage of his compensation on a pre-tax
basis to the Profit Plan.  Such pre-tax contributions may not be less than 1%
of an employee's pre-tax compensation, nor more than the maximum percentage
specified in advance by the Bank.  The annual amount of an employee's pre-tax
contributions may not exceed the  maximum permitted by law.  The adjusted
annual limit for 1991 was $8,475.  If an employee's pre-tax contributions
exceed the annual limit, the excess will be returned to the employee no later
than April 15 after the close of the year in which the contributions were made.
In addition to this annual limit, the pre-tax contributions of highly
compensated employees, as defined in the Internal Revenue Code of 1986, as
amended (the "Code"), may be effectively limited to a lesser amount so that the
Profit Plan will comply with the requirements of section 401(k) of the Code.
All pre-tax contributions to the Plan are fully vested and non-forfeitable at
all times.  



                                      66
<PAGE>   70

The Bank may make discretionary contributions to the Profit Plan
for each fiscal year in an amount determined by the Board of Directors.  Such
discretionary contributions, when added to the total pre-tax contributions made
by employees, may not exceed 15% of the total compensation paid to all
employees participating in the Profit Plan during the calendar year.
Discretionary Bank contributions to the Profit Plan, and forfeitures resulting
from employees who terminate employment with the Bank when less than 100%
vested, are allocated among eligible employees who work at least 1000 hours for
the Bank during the calendar year and are still employed on the last day of the
calendar year in accordance with a formula that takes into account each
participant's total compensation and social security wages for the year.  All
discretionary Bank contributions and forfeitures allocated to an employee under
the Profit Plan become fully vested when the employee reaches age 65 or dies or
becomes totally disabled.  If an employee terminates employment before reaching
age 65 for any reason other than death or total disability, the discretionary
Bank contributions and forfeitures allocated to him under the Profit Plan vest
at the rate of 20% for each year in which the employee works at least 1,000
hours for the Bank beginning with the second such year.

Amounts allocated to an employee's pre-tax contribution and discretionary Bank
contribution accounts under the Profit Plan are invested in the Bank's Common
Stock, the General Fund of investments selected by the trustee of the Profit
Plan, and the Secured Deposit Fund.  An employee may change his investment
election as to future contributions in January of each year.  Each employee is
entitled to instruct the trustee with respect to voting, and in the event of a
tender offer for the Bank's Common Stock, tendering the shares of the Bank's
Common Stock that are credited to the employee's accounts under the Profit
Plan.

Generally, payment to an employee of his vested interest in the Profit Plan
commences after the next year-end valuation following the employee's
termination of employment with the Bank.  Payment is made either in a lump sum
or in equal installments over a period not exceeding ten years. With the Bank's
consent, an employee may make withdrawals from the vested portions of his
pre-tax contribution and discretionary Bank contribution accounts because of
financial hardship whether or not he has terminated employment.  In addition, a
fully vested employee who has reached the age 59 1/2 may withdraw up to his
entire interest in the plan at any time.

During 1991, there were no distributions to the Bank's Executive Officers
pursuant to the Profit Plan.  As of December 31, 1991, the vested amount in the
Profit Plan with respect to the five Executive Officers, including Herbert
Foster who resigned from the Bank in July, 1991, was $945,495.31.  In February,
1992, $218,396.48 was distributed to Herbert Foster.

Compensation of Directors

In 1991, each non-management director of the Bank was paid $1,000 per month.
Directors Emeriti and Honorary Directors were each paid $500 per month.  The
total compensation paid to all non-management directors in 1991 was $101,500.

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Transactions With Management

Mr. Leonard Ware, a director of the Bank, is of counsel to Ware & Freidenrich,
A Professional Corporation, counsel to the Bank.  Such firm provides legal
services to the Bank at rates not in excess of the standard hourly rates of the
firm.

Indebtedness of Management

The Bank has had, and expects to have in the future, banking transactions in
the ordinary course of its business with directors, officers, principal
shareholders and their associates, on the same terms, including interest rates
and collateral on loans, as those prevailing at the same time for comparable
transactions with others, and which, in the opinion of the Bank's management,
do not involve a greater risk of collectibility.  Furthermore, it is the Bank's
policy to preclude its executive officers from borrowing from the Bank and any
loan to a director must be approved by the entire Board of Directors.

At no time since January 1, 1991 has the Bank had any outstanding aggregate
extensions of credit to individual Bank Directors, Executive Officers,
Principal shareholders, or their associates, exceeding ten percent (10%) of the
equity capital of the Bank.

                         NOTES TO FINANCIAL STATEMENTS

                         Quarter ended March 31, 1992


The financial statements included herein are unaudited.  The information
furnished herein reflects all adjustments which are, in the opinion of
management, necessary to a fair statement of the results of the interim period
ended March 31, 1992.  

NOTE A - Summary of Significant Accounting Policies

Investment Securities

Investment securities, which are generally held to maturity, are stated at
cost, adjusted for the accretion of discounts and amortization of premiums
using the straight line method.

Loans

Loans are stated net of undisbursed funds.  Interest on commercial, consumer
installment and real estate loans is accrued on a simple interest basis.
Interest on loans is not accrued in those instances where management considers
principal amounts doubtful of collection.

Loan Fees

Nonrefundable fees for loan origination and commitments in excess of direct
costs of originating the loan or commitment are amortized over the life of the
loan using the straight line method.  Fees originated since 1988 are recognized
as income using the interest method as required by FASB 91.

Allowance for Loan Losses

The allowance for loan losses is established through charges to earnings in the
form of a provision for loan losses.  Loans which are determined to be
uncollectible are charged against this allowance, and subsequent recoveries, if
any, are credited to the allowance.

The allowance for loan losses is an amount that management believes will be
adequate to absorb possible losses on existing loans that may become
uncollectible, based on evaluations of the collectability of loans and prior
loan experience.  The evaluations take into consideration such factors as
changes in the nature and volume of specific problem loans and current or
anticipated economic conditions that may affect the borrowers' ability to pay.

                                       12
<PAGE>   14
Premises and Equipment

Premises and equipment are stated at cost, less accumulated depreciation and
amortization.  Leasehold improvements are amortized over the life of the
respective lease or the estimated useful lives of the improvements, whichever
is the shorter period.  Depreciation is computed using the straight line method
over estimated useful lives of the assets.

Income Per Share of Common Stock

Net income per share is based upon the weighted average number of common shares
outstanding adjusted by the dilutive effect of stock options outstanding on a
fully diluted basis.


NOTE B - Provision for Income Taxes

No portion of income tax provision is attributable to foreign operations.  The
provision for income tax has been calculated taking into account the tax-exempt
status of portions of municipal bond income.  Of the federal statutory income
tax rate of 34%, the following are the components of the current quarter
provision:

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

Capital

During the first quarter of 1992, the Bank's capital increased by $648,751, or
2.78%, compared to an increase of $650,347, or 2.90% in the same period of
1991.  Sources of additional capital in each of the periods were retained
earnings, exercise of stock options and purchases of new stock by the Bank's
profit sharing and 401K plans.  The Bank paid a dividend of fifty-five cents a
share to shareholders of record February 3, 1992, or a total of $713,501
compared to a dividend of forty-five cents per share, or a total of $560,021 in
the same period of 1991.

The Bank is subject to Office of the Comptroller of the Currency's regulations.
In 1989, the Comptroller established risk-based capital guidelines for national
banks.  The Federal Reserve Board and the FDIC have issued similar guidelines
for bank holding companies and state banks.  The guidelines define Tier 1
Capital and Total Capital.  Tier 1 Capital consists of common and qualifying
preferred shareholder's equity and minority interests in equity accounts of
consolidated subsidiaries.  Total Capital consists of, in addition to Tier 1
Capital, mandatory convertible debt, preferred stock not qualifying as Tier 1
Capital, subordinated and other qualifying term debt and a portion of the
allowance for loan losses less the remaining 50% of investments in
unconsolidated subsidiaries.  The Tier 1 component must comprise at least 50%
of qualifying Total Capital.  Risk-based capital ratios are calculated with
reference to risk-weighted assets which include both on and off-balance sheet
exposures.  The guidelines provide for a transition period that extends through
the end of 1992.  As of December 31, 1990, the minimum required ratio for
qualifying Total Capital (including grandfathered goodwill) using the 1990
transition rules is 7.25% of which 3.625% must be Tier 1 Capital.  After the
end of 1992, the minimum required qualifying total capital ratio will be 8%, of
which at least 4% must consist of Tier 1 Capital.  At March 31, 1992, the
Bank's Tier 1 Capital totaled $25,840,000 and Total Capital was $27,932,000.
The Bank's Tier 1 capital to total risk weighted assets ratio was 10.76% and
its Total Capital to total risk weighted assets ratio was 11.63%.

It is the intention of the Bank to continue capital augmentation through
earnings retention net of dividends in future years.

Liquidity

Historically, the Bank's balance sheet has shown a high degree of liquidity.
The following table shows balance sheet proportions for the quarter ending
March 31, 1992 and for the years ending December 31, 1991 and December 31,
1990.

Totals may not add due to rounding.

Bank assets containing a high degree of liquidity are Cash & Due From Banks,
Investment Securities and Federal Funds Sold.  For the quarter ending March 31,
1992, those assets comprised 33.96% of the Bank's assets compared to 35.86% in
1991 and 36.01% in 1990.

A principal source of liquidity is new deposit generation.  Historically, loan
generation has lagged deposit growth.  That trend reversed in 1988 and
continued to the current quarter.  The loan to deposit ratio decreased from
64.37% in 1990 to 64.21% in 1991 and  increased to 66.11% in the first quarter
of 1992.  Growth rates for the first quarter of 1992 and for the years 1991 and
1990 are shown in the following table.

The investment portfolio is another source of liquidity.  While a portion of
the portfolio is intended to be a permanent investment, a portion is invested
in short-term obligations pending re-employment

                                       15

of these funds in the loan portfolio or for deposit withdrawals.  As of March
31, 1992, the investment portfolio totaled $70,952,051.  Of that amount,
$10,000,668, or 14.09% of the total portfolio matures  within one year.
Additionally, the securities in the portfolio are freely marketable.

Within the loan portfolio are investments in short term bankers acceptances
totaling $7,898,191 at March 31, 1992.  These acceptances all mature within 180
days.

Other internal sources of liquidity are the retention of earnings and cash flow
generated in the loan portfolio.

External sources of liquidity include borrowings available to the Bank.  As of
March 31, 1992, the Bank has two lines available totaling $8,000,000 of which
$5,000,000 is committed until June 30, 1992, and on which commitment fees have
been paid.  $3,000,000 is on an "as available" basis.

Indebtedness of Management

The Bank has had, and expects to have in the future, banking transactions in
the ordinary course of its business with directors, officers, principal
shareholders and their associates, on the same terms, including interest rates
and collateral on loans, as those prevailing at the same time for comparable
transactions with others, and which, in the opinion of the Bank's Management,
do not involve a greater risk of collectibility.  Furthermore, it is the Bank's
policy to preclude its executive officers from borrowing from the Bank and any
loan to a director must be approved by the entire Board of Directors.

The following table summarizes the loans to Directors and Principal Holders of
Equity Securities in the quarter ended March 31, 1992:

</TABLE>

During the period ended March 31, 1992, none of these loans became past due or
was placed on non-accrual.

Results of Operations

In the quarter ended March 31, 1992, average daily assets increased by $47.9
million or 16.75% over the first quarter 1991 and increased by $230 thousand,
or less than 1%, over the fourth quarter of 1991.  Deposits and other
borrowings increased $44.6 million, or 17.03%


                                       16
<PAGE>   18
over the first quarter of 1991 and increased $143 thousand, or 0.05% over the
fourth quarter of 1991.

The mix in earning assets reflects a increase in loan demand.  Loans, net of
banker's acceptances, as a percent of earning assets were 66.17% for the
quarter ended March 31, 1992, compared to 66.07% for the first quarter of 1991
and 60.91% for the fourth quarter of 1991.

Net Interest Income and Margin

In the three months ended March 31, 1992, net interest income on a fully
taxable equivalent basis increased $285,000, or 7.66% from the preceding
quarter and increased $496,000, or 14.14%, over the same period in 1991.

Interest-earning assets averaged $297.1 million, an increase of $41.8 million,
or 16.35%, over the same period in 1991.  Interest earned on those assets
decreased $267,000, or 4.08%, for a total of $6,274,000 in this period.  The
composite fully taxable equivalent yield on interest-earning assets decreased
from 10.39% in the first quarter of 1991 to 8.49% in the current period.
Compared with the preceding period, interest on earning assets decreased
$457,000, or 6.79%.  Yields decreased fifty nine basis points from 9.08% to
8.49%.

Average interest-bearing liabilities increased by $44.6 million to $306.4
million, or 17.03% over the same period in 1991.  Interest expense decreased
$763,000, or 25.16%.  The composite average cost of funds decreased from 4.70%
to 2.98%.  In this quarter, compared to the prior quarter, the cost of funds
decreased by one hundred one basis points from 3.99% to 2.98%.  Net interest
margin decreased from 5.57% in the first quarter of 1991 to 5.02% in the fourth
quarter of 1991 and increased to 5.42% in the current quarter.

Non-Interest Income

In this period, non-interest income increased $115,900, or 19.63% over the same
period in 1991 and increased $37,700, or 5.63% from the prior period.
Non-interest income is derived from Trust Department fees, service charges on
deposit accounts, other fees and charges and safe deposit rentals.  In this
period, trust fees accounted for $455,800 or 50.28% of non-interest revenue.
Increases in non-interest income over the prior year are due to increased
volume of trust business.  

Non-Interest Expense

Non-interest expense increased $307,800, or 12.03%, in this period compared to
the same period in 1991, and increased $232,700 or 8.84% over the prior period.
Overall increases in non-interest expense are due to increases in deposits and
earning assets and increased staff and other costs necessary to service this
growth.  Increases are also due to the opening of an additional banking floor
in Menlo Park and a Trust Representative office in Santa Cruz in the fourth

quarter of 1989 and the establishment of an operations center in Menlo Park in
the current period.

Provision for Loan and Lease Losses

The Bank provided $300,000 for loan losses in this period compared to $150,000
in the first quarter of 1991 and to $425,000 in the fourth quarter of 1991.
The Bank's Reserve for Loan Losses is maintained at a level that Management
believes will be adequate to absorb possible losses. Management evaluations
take into consideration such factors as changes in the nature and volume of
specific problem loans and current economic conditions that may affect the
borrower's ability to repay.

Letters of Credit

At March 31, 1992, the Bank's commitments under unused letters of credit were
$7,509,000 of which 20% are reasonably expected to be exercised within the next
twelve months.  At March 31, 1991, such commitments totaled $6,627,000 and at
December 31, 1991, $8,048,000.

  INTEREST RATES AND NET INTEREST DIFFERENTIAL

The major portion of the Bank's income results from the difference between      
interest income derived from earning assets and interest expense paid on
liabilities incurred primarily for the funding of those assets.  The difference
is referred to as net interest income.  Net interest income expressed as a
percent of average total earning assets is referred to as net interest margin. 
Net interest income and net interest margin are summarized in the following
comparisons for the three months ended March 31, 1992 over the same period in
1991 and for the three months ended December 31,1991.  Average balances are
expressed in thousands of dollars:

                         NOTES TO FINANCIAL STATEMENTS

                         Quarter ended June 30, 1992


The financial statements included herein are unaudited.  The information
furnished herein reflects all adjustments which are, in the opinion of
management, necessary to a fair statement of the results of the interim period
ended June 30, 1992.
 
NOTE A - Summary of Significant Accounting Policies

Investment Securities

Investment securities, which are generally held to maturity, are stated at
cost, adjusted for the accretion of discounts and amortization of premiums
using the straight line method.

Loans

Loans are stated net of undisbursed funds.  Interest on commercial, consumer
installment and real estate loans is accrued on a simple interest basis.
Interest on loans is not accrued in those instances where management considers
principal amounts doubtful of collection.

Loan Fees

Nonrefundable fees for loan origination and commitments in excess of direct
costs of originating the loan or commitment are amortized over the life of the
loan using the straight line method.  Fees originated since 1988 are recognized
as income using the interest method as required by FASB 91.

Allowance for Loan Losses

The allowance for loan losses is established through charges to earnings in the
form of a provision for loan losses.  Loans which are determined to be
uncollectible are charged against this allowance, and subsequent recoveries, if
any, are credited to the allowance.

The allowance for loan losses is an amount that management believes will be
adequate to absorb possible losses on existing loans that may become
uncollectible, based on evaluations of the collectability of loans and prior
loan experience.  The evaluations take into consideration such factors as
changes in the nature and volume of specific problem loans and current or
anticipated economic conditions that may affect the borrowers' ability to pay.

                                       13
<PAGE>   39
Premises and Equipment

Premises and equipment are stated at cost, less accumulated depreciation and
amortization.  Leasehold improvements are amortized over the life of the
respective lease or the estimated useful lives of the improvements, whichever
is the shorter period.  Depreciation is computed using the straight line method
over estimated useful lives of the assets.

Income Per Share of Common Stock

Net income per share is based upon the weighted average number of common shares
outstanding adjusted by the dilutive effect of stock options outstanding on a
fully diluted basis.


NOTE B - Provision for Income Taxes

No portion of income tax provision is attributable to foreign operations.  The
provision for income tax has been calculated taking into account the tax-exempt
status of portions of municipal bond income.  Of the federal statutory income
tax rate of 34%, the following are the components of the current quarter
provision:

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

Capital

During the second quarter of 1992, the Bank's capital increased by $1,041,003,
or 4.03%, compared to an increase of $889,455, or 3.86% in the same period of
1991.  Sources of additional capital in each of the periods were retained
earnings, exercise of stock options and purchases of new stock by the Bank's
profit sharing and 401K plans.  No dividends were paid in the period.

The Bank is subject to Officer of the Comptroller of the Currency's
regulations.  In 1989, the Comptroller established risk-based capital
guidelines for national banks.  The Federal Reserve Board and the FDIC have
issued similar guidelines for bank holding companies and state banks.  The
guidelines define Tier 1 Capital and Total Capital.  Tier 1 Capital consists of
common and qualifying preferred shareholder's equity and minority interests in
equity accounts of consolidated subsidiaries.  Total Capital consists of, in
addition to Tier 1 Capital, mandatory convertible debt, preferred stock not
qualifying as Tier 1 Capital, subordinated and other qualifying term debt and a
portion of the allowance for loan losses less the remaining 50% of investments
in unconsolidated subsidiaries.  The Tier 1 component must comprise at least
50% of qualifying Total Capital.  Risk-based capital ratios are calculated with
reference to risk-weighted assets which include both on and off-balance sheet
exposures.  The guidelines provide for a transition period that extends through
the end of 1992.  As of December 31, 1990, the minimum required ratio for
qualifying Total Capital (including grandfathered goodwill) using the 1990
transition rules is 7.25% of which 3.625% must be Tier 1 Capital.  After the
end of 1992, the minimum required qualifying total capital ratio will be 8%, of
which at least 4% must consist of Tier 1 Capital.  At June 30, 1992, the Bank's
Tier 1 Capital totaled $26,881,124 and Total Capital was $29,964,330.  The
Bank's Tier 1 capital to total risk weighted assets ratio was 11.24% and its
Total Capital to total risk weighted assets ratio was 12.53%.

It is the intention of the Bank to continue capital augmentation through
earnings retention net of dividends in future years.

Liquidity

Historically, the Bank's balance sheet has shown a high degree of liquidity.
The following table shows balance sheet proportions for the quarter ending June
30, 1992 and for the years ending December 31, 1991 and December 31, 1990.

Totals may not add due to rounding.

Bank assets containing a high degree of liquidity are Cash & Due From Banks,
Investment Securities and Federal Funds Sold.  For the quarter ending June 30,
1992, those assets comprised 34.46% of the Bank's assets compared to 35.86% in
1991 and 36.01% in 1990.

A principal source of liquidity is new deposit generation.  Historically, loan
generation has lagged deposit growth.  That trend reversed in 1988 and
continued through 1991.  In the second quarter of 1992, the deposit growth rate
of 2.85% outpaced the loan growth rate of 2.06%.  The loan to deposit ratio
increased from 64.37% in 1990 and decreased to 64.21% in 1991 and increased to
65.61% in the second quarter of 1992.  Growth rates for the second quarter of
1992 and for the years 1991 and 1990 are shown in the following table.

The investment portfolio is another source of liquidity.  While a portion of
the portfolio is intended to be a long term investment, a portion is invested
in short-term obligations pending re-employment of these funds in the loan
portfolio or for deposit withdrawals.  As

of June 30, 1992, the investment portfolio totaled $68,939,054.  Of that amount,
$714,737 matures  within one year.  Additionally, the securities in the
portfolio are freely marketable.  As of June 30, 1992, the portfolio contained
unrealized appreciation of $3,060,000.

Within the loan portfolio are investments in short term bankers acceptances
totaling $3,934,665 at June 30, 1992.  These acceptances all mature within 180
days.

Other internal sources of liquidity are the retention of earnings and cash flow
generated in the loan portfolio.

External sources of liquidity include borrowings available to the Bank.  As of
June 30, 1992, the Bank has two lines available totaling $8,000,000 of which
$5,000,000 is committed until June 30, 1993, and on which commitment fees have
been paid.  $3,000,000 is on an "as available" basis.

Indebtedness of Management

The Bank has had, and expects to have in the future, banking transactions in
the ordinary course of its business with directors, officers, principal
shareholders and their associates, on the same terms, including interest rates
and collateral on loans, as those prevailing at the same time for comparable
transactions with others, and which, in the opinion of the Bank's Management,
do not involve a greater risk of collectibility.  Furthermore, it is the Bank's
policy to preclude its executive officers from borrowing from the Bank and any
loan to a director must be approved by the entire Board of Directors.

The following table summarizes the loans to Directors and Principal Holders of
Equity Securities in the quarter ended June 30, 1992:

Results of Operations

In the quarter ended June 30, 1992, average daily assets increased by $51.8
million or 17.32% over the second quarter 1991 and increased by $16.8 million,
or 5.03%, over the first quarter of 1992.  Deposits and other borrowings
increased $49.6 million, or

<PAGE>   43
18.16% over the second quarter of 1991 and increased $16.3 million, or 5.32%
over the first quarter of 1992.

The mix in earning assets reflects a increase in loan demand over the second
quarter of 1991 and a decrease in loan demand from the first quarter of 1992 to
the current quarter.  Loans, as a percent of earning assets were 66.56% for the
quarter ended June 30, 1992, compared to 65.15% for the second quarter of 1991
and 68.83% for the first quarter of 1992.

Net Interest Income and Margin

In the three months ended June 30, 1992, net interest income on a fully taxable
equivalent basis increased $108,000, or 2.70% from the preceding quarter and
increased $596,000, or 16.95%, over the same period in 1991.

Interest-earning assets averaged $314.7 million, an increase of $49.2 million,
or 18.52%, over the same period in 1991.  Interest earned on those assets
decreased $189,000, or 2.90%, for a total of $6,332,000 in this period.  The
composite fully taxable equivalent yield on interest-earning assets decreased
from 9.85% in the second quarter of 1991 to 8.07% in the current period.
Compared with the preceding period, interest on earning assets increased
$58,000, or 0.92%.  Yields decreased forty two basis points from 8.49% to
8.07%.

Average interest-bearing liabilities increased by $49.6 million to $322.7
million, or 18.16% over the same period in 1991.  Interest expense decreased
$785,000, or 26.13%.  The composite average cost of funds decreased from 4.41%
to 2.76%.  In this quarter, compared to the prior quarter, the cost of funds
decreased by twenty one basis points from 2.98% to 2.76%.  Net interest margin
increased from 5.31% in the second quarter of 1991 to 5.42% in the first
quarter of 1992 and decreased to 5.24% in the current quarter.

Non-Interest Income

In this period, non-interest income increased $97,000, or 15.72% over the same
period in 1991 and increased $7,000, or 0.99% from the prior period.
Non-interest income is derived from Trust Department fees, service charges on
deposit accounts, other fees and charges and safe deposit rentals.  In this
period, trust fees accounted for $479,000 or 67.09% of non-interest revenue.

Net Gains on Sales/Calls of Securities

Following a change in Investment Policy, the entire U. S. Government portfolio
was sold producing a net gain of $790,000 in the current period.  In the first
quarter of 1992, the gain on calls of securities totaled $46,100.  There were
no security sales in the second quarter of 1991.

                                       18

Non-Interest Expense

Non-interest expense increased $400,000, or 15.85%, in this period compared to
the same period in 1991, and increased $55,700 or 1.94% over the prior period.
Increases in non-interest expense over the first quarter of 1991 are due to
increases in deposits and earning assets and increased staff and other costs
necessary to service this growth as well as an increase in FDIC insurance
assessment of 42.16% over the second quarter of 1991, to $173,300.

Provision for Loan and Lease Losses

The Bank provided $1,015,233 for loan losses in this period, an increase of
576.82% over the $150,000 provision in the second quarter of 1991.  The
provision in the first quarter of 1992 was $300,000.  The Bank's Reserve for
Loan Losses is maintained at a level that Management believes will be adequate
to absorb possible losses. Management evaluations take into consideration such
factors as changes in the nature and volume of specific problem loans and
current economic conditions that may affect the borrower's ability to repay.

Letters of Credit

At June 30, 1992, the Bank's commitments under unused letters of credit were
$7,088,000 of which 20% are reasonably expected to be exercised within the next
twelve months.  At June 30, 1991, such commitments totaled $7,423,000 and at
March 31, 1991, $7,509,000.

  INTEREST RATES AND NET INTEREST DIFFERENTIAL

  The major portion of the Bank's income results from the difference between
  interest income derived from earning assets and interest expense paid on
  liabilities incurred primarily for the funding of those assets.  The
  difference is referred to as net interest income.  Net interest income
  expressed as a percent of average total earning assets is referred to as
  net interest margin.  Net interest income and net interest margin are
  summarized in the following comparisons for the three months ended
  June 30, 1992 over the same period in 1991 and for the three months
  ended March 31, 1992.  Average balances are expressed in thousands of
  dollars:

                         NOTES TO FINANCIAL STATEMENTS

                        Quarter ended September 30, 1992

The financial statements included herein are unaudited.  The information
furnished herein reflects all adjustments which are, in the opinion of
management, necessary to a fair statement of the results of the interim period
ended September 30, 1992.
 
NOTE A - Summary of Significant Accounting Policies

Investment Securities

Investment securities, which are generally held to maturity, are stated at
cost, adjusted for the accretion of discounts and amortization of premiums
using the straight line method.

Loans

Loans are stated net of undisbursed funds.  Interest on commercial, consumer
installment and real estate loans is accrued on a simple interest basis.
Interest on loans is not accrued in those instances where management considers
principal amounts doubtful of collection.

Loan Fees

Nonrefundable fees for loan origination and commitments in excess of direct
costs of originating the loan or commitment are amortized over the life of the
loan using the straight line method.  Fees originated since 1988 are recognized
as income using the interest method as required by FASB 91.

Allowance for Loan Losses

The allowance for loan losses is established through charges to earnings in the
form of a provision for loan losses.  Loans which are determined to be
uncollectible are charged against this allowance, and subsequent recoveries, if
any, are credited to the allowance.

The allowance for loan losses is an amount that management believes will be
adequate to absorb possible losses on existing loans that may become
uncollectible, based on evaluations of the collectability of loans and prior
loan experience.  The evaluations take into consideration such factors as
changes in the nature and volume of specific problem loans and current or
anticipated economic conditions that may affect the borrowers' ability to pay.

                                       13
<PAGE>   64
Premises and Equipment

Premises and equipment are stated at cost, less accumulated depreciation and
amortization.  Leasehold improvements are amortized over the life of the
respective lease or the estimated useful lives of the improvements, whichever
is the shorter period.  Depreciation is computed using the straight line method
over estimated useful lives of the assets.

Income Per Share of Common Stock

Net income per share is based upon the weighted average number of common shares
outstanding adjusted by the dilutive effect of stock options outstanding on a
fully diluted basis.


NOTE B - Provision for Income Taxes

No portion of income tax provision is attributable to foreign operations.  The
provision for income tax has been calculated taking into account the tax-exempt
status of portions of municipal bond income.  Of the federal statutory income
tax rate of 34%, the following are the components of the current quarter
provision:

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

Capital

During the second quarter of 1992, the Bank's capital increased by $163,879,  
or .61%, compared to an increase of $362,601, or 1.51% in the same period of
1991.  Sources of additional capital in each of the periods were retained
earnings, exercise of stock options and purchases of new stock by the Bank's
profit sharing and 401K plans.  The Bank paid a dividend of $0.55 per share to
shareholders of record July 30, 1992.  This compares to a dividend of $0.55 per
share in the same period of 1991.

The Bank is subject to Officer of the Comptroller of the Currency's
regulations.  In 1989, the Comptroller established risk-based capital
guidelines for national banks.  The Federal Reserve Board and the FDIC have
issued similar guidelines for bank holding companies and state banks.  The
guidelines define Tier 1 Capital and Total Capital.  Tier 1 Capital consists of
common and qualifying preferred shareholder's equity and minority interests in
equity accounts of consolidated subsidiaries.  Total Capital consists of, in
addition to Tier 1 Capital, mandatory convertible debt, preferred stock not
qualifying as Tier 1 Capital, subordinated and other qualifying term debt and a
portion of the allowance for loan losses less the remaining 50% of investments
in unconsolidated subsidiaries.  The Tier 1 component must comprise at least
50% of qualifying Total Capital.  Risk-based capital ratios are calculated with
reference to risk-weighted assets which include both on and off-balance sheet
exposures.  The guidelines provide for a transition period that extends through
the end of 1992.  As of December 31, 1990, the minimum required ratio for
qualifying Total Capital (including grandfathered goodwill) using the 1990
transition rules is 7.25% of which 3.625% must be Tier 1 Capital.  After the
end of 1992, the minimum required qualifying total capital ratio will be 8%, of
which at least 4% must consist of Tier 1 Capital.  At September 30, 1992, the 
Bank's Tier 1 Capital totaled $27,045,003 and Total Capital was $30,784,132. 
The Bank's Tier 1 capital to total risk weighted assets ratio was 10.77% and its
Total Capital to total risk weighted assets ratio was 12.26%.

It is the intention of the Bank to continue capital augmentation through
earnings retention net of dividends in future years.

Liquidity

Historically, the Bank's balance sheet has shown a high degree of liquidity.
The following table shows balance sheet proportions for the quarter ending
September 30, 1992 and for the years ending December 31, 1991 and December 31, 
1990.

Totals may not add due to rounding.

Bank assets containing a high degree of liquidity are Cash & Due From Banks,
Investment Securities and Federal Funds Sold.  For the quarter ending September
30, 1992, those assets comprised 33.79% of the Bank's assets compared to 35.86%
in 1991 and 36.01% in 1990.

A principal source of liquidity is new deposit generation.  Historically, loan
generation has lagged deposit growth.  That trend reversed in 1988 and
continued in the present period. In the third quarter of 1992, the loan growth 
rate of 15.54% surpassed the deposit growth rate of 11.85%. The loan to deposit
ratio decreased from 64.37% in 1990 to 64.21% in 1991 and increased to
66.30% in the third quarter of 1992.  Growth rates for the third quarter of
1992 and for the years 1991 and 1990 are shown in the following table.

The investment portfolio is another source of liquidity.  While a portion of
the portfolio is intended to be a permanent investment, a portion is invested
in short-term obligations pending re-employment of these funds in the loan
portfolio or for deposit withdrawals.  As 


                                      16
<PAGE>   67

of September 30, 1992, the investment portfolio totaled $68,992,000.  Of that
amount, $714,000, or 1.03% of the total portfolio matures  within one year. 
Additionally, the securities in the portfolio are freely marketable.  

Other internal sources of liquidity are the retention of earnings and cash flow
generated in the loan portfolio.

External sources of liquidity include borrowings available to the Bank.  As of
September 30, 1992, the Bank has two lines available totaling $8,000,000 of
which $5,000,000 is committed until June 30, 1993, and on which
commitment fees have been paid.  $3,000,000 is on an "as available" basis.

Indebtedness of Management

The Bank has had, and expects to have in the future, banking transactions in
the ordinary course of its business with directors, officers, principal
shareholders and their associates, on the same terms, including interest rates
and collateral on loans, as those prevailing at the same time for comparable
transactions with others, and which, in the opinion of the Bank's Management,
do not involve a greater risk of collectibility.  Furthermore, it is the Bank's
policy to preclude its executive officers from borrowing from the Bank and any
loan to a director must be approved by the entire Board of Directors.

The following table summarizes the loans to Directors and Principal Holders of
Equity Securities in the quarter ended September 30, 1992:

Results of Operations

In the quarter ended September 30, 1992, average daily assets increased by
$30.1 million or 9.50% over the third quarter 1991 and decreased by $4.3
million, or 1.24%, over the second quarter of 1992.  Deposits and other
borrowings increased $28.7 million, or 9.95% over the third quarter of 1991 and 
decreased $5.1 million, or 1.58% over the second quarter of 1992. The mix in
earning assets reflects an increase in loan demand. Loans as a percent of 
earning assets were 71.22% for the quarter ended September 30, 1992,

                                       17

compared to 65.43% for the third quarter of 1991 and 66.56% for the second
quarter of 1992.

Net Interest Income and Margin

In the three months ended September 30, 1992, net interest income on a fully 
taxable equivalent basis increased $182,000, or 4.42% from the preceding 
quarter and increased $655,000, or 17.99%, over the same period in 1991.

Interest-earning assets averaged $308.5 million, an increase of $25.4 million,
or 8.96%, over the same period in 1991.  Interest earned on those assets
decreased $599,000, or 8.82%, for a total of $6,191,000 in this period.  The
composite fully taxable equivalent yield on interest-earning assets decreased
from 9.51% in the third quarter of 1991 to 7.96% in the current period.
Compared with the preceding period, interest on earning assets decreased
$141,000, or 2.23%.  Yields decreased eleven basis points from 8.07% to
7.96%.

Average interest-bearing liabilities increased by $28.7 million to $317.6
million, or 9.95% over the same period in 1991.  Interest expense decreased
$1,254,000, or 39.81%.  The composite average cost of funds decreased from 4.33%
to 2.37%.  In this quarter, compared to the prior quarter, the cost of funds
decreased by thirty nine basis points from 2.76% to 2.37%.  Net interest margin
increased from 5.10% in the third quarter of 1991 to 5.24% in the second
quarter of 1992 and to 5.52% in the current quarter.

Non-Interest Income

In this period, non-interest income increased $110,400, or 17.32% over the same
period in 1991 and increased $38,800, or 5.43% from the prior period.
Non-interest income is derived from Trust Department fees, service charges on
deposit accounts, other fees and charges and safe deposit rentals.  In this
period, trust fees accounted for $490,945 or 65.24% of non-interest revenue. 
Increases in non-interest income over the prior year are due to increased
volume of trust business.

Non-Interest Expense

Non-interest expense increased $214,380, or 8.09%, in this period compared to
the same period in 1991, and decreased $55,800 or 1.91% over the prior period.
Overall increases in non-interest expense are due to increases in deposits and
earning assets and increased staff and other costs necessary to service this
growth. A portion of the increase is due to increased FDIC assessment rates.
FDIC assessment increased by $23,500 or 15.33% to $177,000 in the current
period.

Provision for Loan and Lease Losses

The Bank provided $675,000 for loan losses in this period compared to $150,000
provided in the third quarter of 1991 and $1,015,233

                                       18
<PAGE>   69
in the second quarter of 1992. The Bank's Reserve for Loan Losses is maintained
at a level that Management believes will be adequate to absorb possible
losses. Management evaluations take into consideration such factors as changes
in the nature and volume of specific problem loans and current economic
conditions that may affect the borrower's ability to repay.

Letters of Credit

At September 30, 1992, the Bank's commitments under unused letters of credit 
were $5,927,882 of which 20% are reasonably expected to be exercised within
the next twelve months.  At September 30, 1991, such commitments totaled 
$7,519,343 and at June 30, 1992, $7,088,000.

  INTEREST RATES AND NET INTEREST DIFFERENTIAL

  The major portion of the Bank's income results from the difference between
  interest income derived from earning assets and interest expense paid on
  liabilities incurred primarily for the funding of those assets.  The
  difference is referred to as net interest income.  Net interest income
  expressed as a percent of average total earning assets is referred to as
  net interest margin.  Net interest income and net interest margin are
  summarized in the following comparisons for the three months ended
  September 30, 1992 over the same period in 1991 and for the three months
  ended June 30, 1992.  Average balances are expressed in thousands of
  dollars:

                                PROXY STATEMENT
                    INFORMATION CONCERNING THE SOLICITATION

        The  enclosed Proxy is  solicited on behalf of the Board of 
Directors of University National Bank & Trust Company, a national banking
association (the "Bank"), for use  at the Annual Meeting of Shareholders to be 
held at the Bank, 250  Lytton Avenue, Palo Alto, California at 4:30 p.m. on
Thursday, May 7, 1992.  Only shareholders of record on  March 18, 1992, will be
entitled to vote.  At the close of business on that date, the Bank had
outstanding 1,274,806 shares of its $2.50 par value Common Stock (the "Common 
Stock"). Unless  otherwise specified, all references herein to the par value
of the Common Stock, outstanding shares of the Common Stock, shares
beneficially owned, options held, exercise prices of options, or otherwise
referring to ownership of the Common Stock, reflect the two-for-one stock
split that  was approved by the Bank's shareholders on November 2, 1989.

        Shareholders of  Common Stock are entitled to  one vote for each  share
held, except that, in the election of Directors, each shareholder has
cumulative voting rights and is entitled to as many votes as shall equal the
number of shares held by him or her multiplied by the number of Directors to
be elected, and he or she may cast all of his or her votes for a single
candidate or may distribute his or her votes among any or all of the
candidates as he or she chooses.

        Any person giving a proxy in the form accompanying this statement 
has the power to revoke or suspend it prior to its exercise.  It is
revocable prior to the meeting by an instrument revoking it or by a duly
executed proxy bearing a later date, delivered to the Secretary of the Bank.  
It is suspended if the shareholder is  present at the meeting and elects to
vote in  person.  If the shareholder does not specify otherwise, such 
shares will be voted (i) in favor of the nominees named herein for
election as Directors (and, in the proxy holders' discretion, such shares
may be voted cumulatively as the proxy holder deems appropriate so  as to
maximize the number of named nominees that are elected), (ii) in favor  of the
proposal to amend the University National Bank & Trust Company's 1980 Stock 
Option Plan to provide for the granting of options thereunder until January
23, 2002 and to increase the number of shares reserved thereunder from 280,320
shares to 330,320 shares, (iii) in favor of the proposal to approve the
adoption of the University National Bank & Trust Company Outside Directors
Stock Option Plan, and (iv) at the proxy holders' discretion, on such other
matters, if any, which may come before the meeting (including any proposal to
adjourn the meeting).

        The Bank will bear the entire cost of preparing, assembling, 
printing and mailing  proxy materials furnished by the Board of Directors to
shareholders. Copies of proxy materials will be furnished to brokerage
houses, fiduciaries and custodians to be forwarded to the beneficial owners of
the Common Stock. In addition to the solicitation of proxies by use of the
mail, some officers, Directors and regular employees of the Bank may (without
additional compensation) solicit proxies by telephone or personal interview,
the cost of which the Bank will bear.

        March 30, 1992 is the approximate date on which this Proxy Statement
and form of Proxy were first sent or given to shareholders.

                     PROPOSAL NO. 1 - ELECTION OF DIRECTORS

         The Bylaws of the  Bank provide a procedure for nomination for
election of members of the Board of Directors, which procedure is printed in
full  in the Notice of Annual Meeting  of Shareholders accompanying this Proxy
Statement.  Nominations not  made in accordance therewith may, in  his
discretion, be disregarded  by the Chairman  of the Meeting and,  upon his
instruction,  the inspector of  elections shall disregard all votes cast for
such nominee(s).

         The Bylaws of the Bank  provide that the Board of Directors may fix
the number of Directors at any number between five  (5) and twenty- five (25),
inclusive.   The Board of  Directors, pursuant to  its authority,  has set  the
number of  Directors at  ten (10)  and all ten  (10) Directors are to be
elected at  this meeting to hold office until the next Annual Meeting of
Shareholders and until their successors are elected and  qualify.  Unless
otherwise cumulatively voted so as to  maximize the number of recommended
nominees  elected, all proxies will be voted for the election of  the ten (10)
nominees recommended  by the Board of  Directors, unless authority to  vote for
the  election of Directors or  any Director  is withheld.   All of the
nominees are incumbent  Directors of the Bank.   If any of  the nominees should
unexpectedly decline or be unable  to act as  a Director, the  proxies may be
voted  for a substitute  nominee to be  designated by the  Board of Directors.
The Board of Directors has no reason to believe that any nominee will become
unavailable and  has no present intention to nominate persons in addition to
or in lieu of those named below.

         The table  on the  following page  sets forth information  with
respect  to each person  nominated for  election as  a Director and  all
Directors and Executive  Officers as a group.  All of  the shares shown in the
following table are owned both  of record and beneficially except as indicated
in the notes to the table.

as a banking consultant from 1978 to 1979 and was Superintendent of Banks of
the State of California from 1975 to 1978.

         Leonard Ware was a partner with Ware & Freidenrich, A Professional
Corporation, a law firm in Palo Alto, from 1969 to 1981.   Currently, he is Of
Counsel to that firm.

Committees of the Board of Directors

         The Board of Directors of the Bank has established an  Audit Committee
and a Compensation Committee.  The members of the Audit Committee are J. Boyce
Nute as Chairperson, Lawrence A. Aufmuth, George G. C. Parker,  and Betsy
Morgenthaler.  The members of the Compensation Committee are William A.
Preston, as Chairperson, Linda R. Meier, and Lawrence A. Aufmuth.

         The  Audit Committee met  four times  during 1991.   The functions of
the Audit  committee are to  recommend the appointment  of and to oversee a
firm  of independent public accountants, whose  duty it is to audit the  books
and records of the  Bank for the fiscal  year for which they  are appointed, to
monitor  and analyze the results  of the internal and regulatory  examinations,
and to monitor  the Bank's financial and accounting organization and financial
reporting.

         The Compensation Committee met once during 1991.  The function of the
Compensation  Committee is to make recommendations to the Board of Directors
regarding the compensation  of the Executive Officers  of the Bank.  The  Board
of Directors makes  the final decision regarding  such matters.

         The Bank does not have a nominating committee.  The Board of Directors
of the Bank performs the function of a nominating committee.

         The full Board of Directors had six regular meetings and one special 
meeting during 1991.

         In 1991 all incumbent Directors  of the Bank attended at  least 75% of
the meetings  of the Board of  Directors and the meetings of  all committees,
including the Audit and Compensation Committees, on which each Director serves.

Profit Sharing Plan

         Effective as of January 1, 1981, the Bank  adopted the Employees'
Profit Sharing Plan, which  was most recently amended and restated  in its
entirety effective January 1, 1988, as the University National Bank & Trust
Company Employees'  Profit Sharing and Tax Deferred Savings Plan (as so
amended, the "Profit Plan").  A First Amendment to the Profit Plan was adopted
by the Bank on June 26, 1989.

         Each employee  of the Bank  becomes eligible to participate  in the
Profit  Plan beginning January 1 following  his date of hire.   Each eligible
employee is permitted to contribute  a specified percentage of his
compensation on a pre-tax basis  to the Profit Plan.  Such pre-tax
contributions may not  be less than 1%  of an employee's compensation,  nor
more than the  maximum percentage specified in  advance by the Bank.  The
annual amount  of an employee's pre-tax  contributions may not  exceed the
maximum amount  permitted by law.   The annual limit for  1992 is $8,728.  In
addition to this annual limit, the  pre-tax contributions of highly compensated
employees,  as defined in the Internal Revenue  Code of 1986, as amended  (the
"Code") may be  effectively limited to a lesser  amount so that the Profit Plan
will comply with the  requirements of section 401(k) of the Code.  All pre-tax
contributions to the Plan are fully vested and non-forfeitable at all times.

         The  Bank may  make discretionary  contributions to  the  Profit Plan
for each  fiscal year  in an  amount determined  by the  Board of Directors.
Such  discretionary contributions may not exceed  the amount which is
deductible  for federal income tax purposes, generally  15% of the total
compensation paid  to all employees participating in the Profit  Plan during
the fiscal year  less the aggregate amount of  employees' pre-tax contributions
for the  year.   Discretionary  Bank contributions  to the  Profit Plan,  and
forfeitures  resulting from  employees  who terminate  employment with the Bank
when less than 100%  vested, are allocated among  eligible employees who work
at least 1,000 hours for the Bank during  the calendar year and are still
employed on the last  day of the year,  or who have died  or retired during the
year.   The Bank's discretionary contributions and  forfeitures are  allocated
to  eligible participants' accounts  in accordance  with a  formula that takes
into account each participant's total compensation and social security wages
for the year.

         All  discretionary Bank contributions  and forfeitures  allocated to
an employee  under the Profit  Plan become  fully vested  when the employee
reaches age 65 or dies or becomes totally disabled.  If  an employee terminates
employment before reaching age 65 for any  reason other than death or total
disability, discretionary Bank  contributions and forfeitures allocated to him
under the Profit  Plan vest at a rate of  20% for each year in which the
employee works at least 1,000 hours for the Bank, beginning with the second
such year.

         Amounts allocated to an employee's pre-tax contribution and
discretionary Bank contribution accounts under the  Profit Plan are invested in
the Bank's  Common Stock, the General Fund of investments  selected by the
trustee of the Profit Plan, and the  Secured Deposit Fund, in such proportions
as the employee elects.   An employee may change his investment election as to
future contributions in January of each year.   Each employee is entitled to
instruct the trustee with respect to voting and, in the  event of a tender
offer for the Bank's Common Stock,  tendering the shares of the Bank's Common
Stock that are credited to the employee's accounts under the Profit Plan.

         Generally, payment to an employee of his  vested interest in the
Profit Plan commences  after the next year-end valuation following  the
employee's termination of employment with the Bank.   Payment is made either in
a lump sum or in equal installments over a  period not exceeding ten  years.
An employee may make withdrawals from  the vested portions of his pre-tax
contribution and discretionary Bank contribution accounts because of financial
hardship whether or not he has terminated employment.  In addition, a fully
vested  employee who has reached age 59-1/2 may withdraw up to his entire
interest in the Profit Plan at any time.

         During 1991, there were no distributions to  the Bank's Executive
Committee pursuant to the  Profit Plan.  As of December 31, 1991,  the vested
amount in  the  Profit Plan with  respect to  the  five Executive  Officers,
including Herbert Foster  who resigned  from  the Bank  in July, 1991, was
$945,495.31.  In February, 1992, $218,396.48 was distributed to Herbert Foster.

Interest of Management and Others in Certain Transactions

         The  Bank has  had, and expects  to have  in the future,  banking
transactions in  the ordinary  course of its  business with directors,
officers, principal shareholders and their associates, on the same terms,
including interest rates  and collateral on loans, as those prevailing at the
same time for comparable transactions with others, and which, in the opinion
of the Bank's management, do not involve a greater risk  of collectibility.
Furthermore,  it is  the Bank's  policy to preclude  its Executive  Officers
from borrowing  from the Bank  and any  loan to  a Director must be approved by
the entire Board of Directors.

         At  no time  since January 1,  1991 has  the Bank  had any
outstanding aggregate  extensions of  credit to  individual  Bank Directors,
Executive Officers, principal shareholders, or their associates, exceeding ten
percent (10%) of the equity capital of the Bank.

         Mr. Leonard Ware, a Director of the Bank,  is Of Counsel to Ware &
Freidenrich, A  Professional Corporation, counsel to the Bank.   Such firm
provides legal services to the Bank at rates not in excess of the standard
hourly rates of the firm.   Such services include preparation of certain
documents filed with the  Comptroller of the Currency, employee profit  sharing
and equity participation plans,  general litigation, and real estate matters.

                PROPOSAL NO. 2 - AMENDMENTS OF STOCK OPTION PLAN

         The Board  of Directors and  management of the  Bank are proposing to
amend the University  National Bank & Trust  Company Stock Option Plan, as
amended (the  "Option Plan"), to provide that options  may be granted
thereunder until January 23, 2002,  and to increase the number of shares
reserved thereunder by 50,000 shares,  to a total of 330,320 shares.   Without
these amendments, the Bank will  not be able to grant any more options because
the Option Plan will have expired by the date of the annual meeting.

         These amendments to  the Option Plan must  be approved by  the
affirmative vote of  a majority of the  outstanding shares of the  Bank's
Common Stock.  The Board of Directors and the  management of the Bank believe
that the proposed amendments to the Option Plan are important with respect  to
retaining the qualified  employees essential to the  success of the Bank.
Therefore,  the Board of Directors  and management of the Bank recommend a vote
"FOR" this proposal.

Description of the Option Plan

         1.      General Background.  In 1980,  the Bank adopted the Option
Plan  which set aside 42,000 (pre-split) shares of the  Common Stock for
options which may be granted to key, full-time salaried officers and employees
of  the Bank.  Non-employee Directors of the Bank may not  be granted options.
The Option Plan was amended  in 1982 with the approval of the Bank's
shareholders to permit the Bank to  grant incentive stock options (as  defined
in the Internal Revenue Code) as well as nonqualified stock options.  The
Option  Plan was amended in 1984, in 1986, and in 1988 with  the approval of
the Bank's shareholders to increase the number  of shares reserved under the
Option Plan  to a total of 130,160 (pre- split) shares.  As a  result of the
two-for-one stock split approved by the  Bank's shareholders on November 2,
1989, the  share reserve doubled to 260,160 shares.  The Option  Plan was
amended in 1990 with the approval of the  Bank's shareholders to increase the
number of shares reserved under the Option Plan to 280,320.

         In January 1987,  in accordance with the terms of  the Option Plan,
the Board of  Directors made minor amendments to  the Option Plan to
incorporate changes  required by  the Tax  Reform Act  of 1986 for  incentive
stock  options.   Such amendments  are reflected in  the following discussion
of the Option Plan.

         As  of March 18, 1992, options  to purchase 286,088 shares  have been
granted under  the Option Plan and grants  for 36,915 have expired unexercised.
Options to  purchase 96,173 shares have been exercised and there are currently
options  outstanding to purchase 153,000 shares, at option prices ranging from
$7.50 to $32.50 per share and which will expire at various times from 1992 to
2002.  Accordingly, 950 shares remain





                                       7
<PAGE>   9
available for grant pursuant to the Option Plan.  If the proposed amendments to
the Option Plan are adopted, the number of shares available for grant will be
increased to 50,950.

         2.      Summary of Provisions.   The exercise price of all options
granted under the Option Plan  must be not less than the fair market value of
the  Bank's Common Stock  on the date the  option is granted;  provided,
however, the exercise price  for any employee (a  "Ten Percent Owner Employee")
owning stock possessing  ten percent (10%) or more  of the total combined
voting power of all  stock of the Bank  must be one hundred ten percent (110%)
of the fair market value of the shares on the grant date.  The fair  market
value of the stock for which an employee may be granted incentive stock options
for any calendar year beginning after January 1,  1987 may not become
exercisable at a rate faster  than $100,000 per year based on the stock's value
measured as of the grant date.

         Unless otherwise provided  by the Board of  Directors, all options
granted  under the Option Plan  are exercisable in five  equal annual
installments, commencing  one year after the date the option is granted.   An
option may not have a term  exceeding ten (10) years; provided any option
granted to a Ten Percent Owner Employee may not have a term exceeding five (5)
years.

         In the  event an employee's employment with the Bank is terminated for
any reason  other than death, disability or cause, the employee's option  will
remain exercisable (to the  extent exercisable at the time of  such
termination) for a period of thirty  (30) days from the date of such
termination.   In the  event the employee's  employment is  terminated for
cause,  the option will  immediately expire upon notice  of such termination.
In  the event the employee's employment  is terminated by the employee's  death
or disability, the option will  remain exercisable (to the extent exercisable
immediately prior to such death or disability) for a period of one year from
the date of such termination.

         Options granted  are subject to  the "sequential exercise  rule" which
means that  these options must  be exercised in  the sequences in which they
are granted, and that  an employee must completely exercise a prior  option
before exercising a subsequent  option.  Compliance with the sequential
exercise rule is not required for  federal or California income tax purposes
for options granted after January 1, 1987.  However, the management of the
Bank has determined that compliance with the  sequential exercise rule is in
the  best interests of the Bank  and will be required as a condition to the
exercise of an option.

         In the event of a merger  or consolidation in which the Bank  is not
the surviving corporation or  the sale of substantially all of  the Bank's
assets, all outstanding options under the Option Plan become immediately
exercisable.

         The  Option Plan provides for  adjustment in the  number of shares  of
Common Stock  authorized under the  Option Plan or  granted to an optionee to
protect against dilution in the event of certain changes in the Bank's
capitalization, including stock splits and stock dividends.

         The Board  of Directors, at any time without the  approval of the
shareholders, may amend or terminate  the Option Plan and may vary the terms of
options to  be granted in the  future, except that the Board  may not increase
the  maximum number of shares  for which options may  be granted in the
aggregate or individually under the Option Plan, change the formula setting the
minimum price at which options may be  granted or exercised, or amend the
requirements as to the class of employees  or officers eligible to receive
options without the approval of  the Bank's shareholders.

         3.      Federal Income  Tax Information.   The following  summary is
intended  only as  a general  guide as to the  federal income  tax consequences
under current law respecting participation in the Option  Plan, and does not
attempt to describe all possible federal or potential state  and local or
other tax consequences  of such participation.   Furthermore, the tax
consequences of options  are complex and  subject to change, and  a taxpayer's
particular situation may be  such that some variation of the described  rules
is applicable.  For example, special tax rules apply to affiliates of the Bank.





                                      8
<PAGE>   10
         Optionees should  consult their own  tax advisors prior  to the
exercise  of any option and  prior to the  disposition of any  shares of Common
Stock acquired upon the exercise of an Option.

                 a.       Incentive  Stock Options.  Options designated as
incentive stock options are  intended to fall within the requirements of the
provisions of section 422A of the Internal Revenue Code of 1986, as amended.
An  optionee recognizes no taxable income as the result of the grant or
exercise of such an option.

         For optionees who do not dispose of  their shares for two years
following the date the option was  granted nor within one year following the
transfer of  the shares upon exercise of the option, the gain on sale of the
shares (which  is defined to be the difference between the sale price and the
purchase  price of the shares) will be taxed  as long-term capital gain.
(Under present  law, however, capital gains are taxed at the same  rate as
ordinary income.)  If an optionee is entitled to  long-term capital gain
treatment upon a sale of the stock, the Bank will not be  entitled to any
deduction for federal  income tax purposes.  If an optionee  disposes of shares
within two years  after the date of grant or within one year from the date of
exercise (a "disqualifying disposition"), the difference between the option
price  and the fair market value of the  shares on the date of  exercise (not
to exceed the  gain realized on the sale  if the disposition is  a transaction
with respect to which a loss, if  sustained, would be recognized) will be taxed
at ordinary income rates at the time of  disposition.  Any gain in excess of
that amount will be a capital gain.   If a loss is recognized, there  will be
no ordinary income, and  such loss will be a capital loss.   A capital gain or
loss will  be long-term if the optionee's holding  period is more than twelve
months.  Any ordinary income recognized by  the optionee upon the disposition
of stock should be deductible by the Bank for federal income tax purposes.

         The difference  between the exercise  price and the  fair market value
of the shares  on the determination  date of an  incentive stock option (which
is  generally the date of  exercise) is an adjustment in  computing the
optionee's alternative  minimum taxable income and  may be subject to an
alternative minimum tax which is paid if such tax exceeds the regular tax for
the  year.  Special rules may apply with respect to certain subsequent sales of
the shares in  a disqualifying disposition,  certain basis  adjustments for
purposes  of computing the  alternative minimum taxable  income on a subsequent
sale  of the shares, and  certain tax credits which may arise  with respect to
optionees  subject to the alternative minimum tax in years beginning on or
after January 1, 1987.

                 b.       Nonqualified Stock Options.  Nonqualified  stock
options have no special tax status.  An  optionee generally recognizes no
taxable income as  the result of the grant of such  an option.  Upon exercise
of an  option, the optionee normally recognizes ordinary income in the amount
of  the difference between the option price and  the fair market value on the
determination date (which is generally  the date of exercise).  If the Optionee
is an employee, such ordinary  income generally is subject to withholding of
income and employment taxes.  Upon  the sale of stock acquired by the exercise
of a nonqualified stock option, any gain or loss, based on the difference
between  the sale price and the fair market value on the  date of recognition
of income, will be taxed as a capital gain  or loss.  A capital gain or loss
will be long-term if the optionee's holding period  is more than twelve  months
from the date of  recognition of income.  No tax  deduction is available to
the Bank with respect  to the grant of the option or the  sale of the stock
acquired pursuant to such  grant.  The Bank should be entitled to a deduction
equal to the amount of ordinary income recognized by the optionee as a result
of the exercise of the option.

                                PROPOSAL NO. 3 -
                APPROVAL OF OUTSIDE DIRECTORS STOCK OPTION PLAN


         The Board  of Directors and  management of the  Bank are proposing
that the shareholders  approve The University National  Bank & Trust Company
Outside Directors Stock Option Plan  (the "Directors Plan"), which was adopted
by the Board of Directors on January 23, 1992, subject to shareholder approval
at this annual meeting.

         The  adoption of the Directors  Plan must be  approved by the
affirmative vote of  a majority of  the outstanding shares  of the Bank's
Common Stock.   The Board of Directors and the  management of the Bank believe
that the Directors Plan is important with  respect to attracting and retaining
qualified directors essential to the success of  the Bank.  Therefore, the
Board of Directors and management of the Bank recommend a vote "FOR" this
proposal.

Description of the Directors Plan

         1.      General Background.  The Board of Directors of the Bank
adopted the Directors Plan on January 23, 1992, subject to shareholder approval
at the annual meeting.  The  Directors Plan provides for the granting of
"nonqualified stock  options" (that is, options which are  not intended to
satisfy the requirements  of Section 422 of the Internal  Revenue Code of 1986,
as amended) to directors  of the Bank  who are not employees of the Bank.  A
total of 20,000 shares of Common Stock are reserved for issuance under the
Directors Plan.





                                      11
<PAGE>   13
         As of the date  of this Proxy Statement, there are  nine non-employee
directors who are eligible  to participate in the  Directors Plan.  As  of
March 18, 1992,  outstanding and  unexercised  options to  purchase  9,000
shares were  held by  nine directors, subject  to shareholder approval, with
exercise prices of $24.75 per share.

         2.      Summary of Provisions.  The  following summary of the
Directors Plan  is qualified in its entirety by the specific  language of the
Directors Plan, a copy of which is available to any shareholder upon request.

         The Directors  Plan is administered by the Board of Directors or a
duly appointed  committee of the Board of Directors.  Options granted under the
Directors Plan are nonqualified stock options.  Only directors of  the Bank who
are not employees of  the Bank or its affiliates (the "Outside Directors") are
eligible to participate in the Directors Plan.

         Upon the  initial adoption of  the Directors  Plan, each Outside
Director then holding  office was automatically  granted an option  to purchase
1,000 shares  of Common Stock subject to  approval of the Directors Plan  by
the Bank's shareholders at this annual  meeting.  Provided the Director Plan is
so approved, each person who becomes an Outside Director in the future will be
automatically granted an option to purchase 1,000 shares of  Common Stock on
the date  such Outside Director commences  service on  the Board.   Options
granted under  the Directors  Plan generally are  exercisable for a period of
six years.  Options  become exercisable in five equal annual  installments,
commencing one year after the date of grant.

         The exercise price of any option granted  under the Directors Plan
will be the fair market value of  the Common Stock of the Bank on the date of
grant, as determined pursuant to the Directors Plan.

         The  aggregate number of shares of Common Stock  reserved for issuance
pursuant to the  exercise of options is 20,000 shares (subject to adjustment in
the  event of stock dividends, stock splits, reverse stock splits,
combinations, reclassifications, or like changes in the capital structure of
the Bank).  All options must be granted, if at all, within 10 years from
January 23, 1992, the date  the Directors Plan was adopted by the Board of
Directors.  Shares subject to an option granted under the Directors Plan may be
purchased for cash or by check.

         If an optionee ceases to be a director of the Bank for any reason,
except death or disability or for "cause", the optionee  may exercise his or
her option (to the extent unexercised  and exercisable on the date the optionee
ceased to be a director) within 30 days after the date of termination of
service  as a director,  but in any  event not  later than the  expiration of
the option  term.  If  an optionee  ceases to be  a director of  the Bank due
to  death or disability, the  optionee (or his  or her legal representative)
may exercise his  or her option  (to the extent unexercised and exercisable on
the date the optionee ceased  to be a director) within 12 months after the date
of termination of  service as  a director, but in  any event not later than
the expiration of the  option term.  If  an optionee ceases to  be a director
of  the Bank for "cause" (as defined in the Directors  Plan), the optionee will
not be  permitted to exercise his or her option  following termination of
service as a director.  The period for exercise  of an option upon termination
of service as a director will be extended under  certain circumstances if
exercise  of the option would be a violation  of applicable federal or state
securities laws, or if  exercise would subject the optionee to suit under
Section 16(b) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act").

         During the lifetime of  the optionee, an option may  be exercised only
by the  optionee.  An option  may not be assigned or  transferred except by
will or by the laws of descent and distribution.

         Generally, in the event of the sale, dissolution, or liquidation of
the Bank, or a  merger or consolidation in which the Bank is not the surviving
or resulting  corporation, all outstanding options will  become fully
exercisable and fully  vested as of a date immediately  prior to the
consummation of such corporate transaction.





                                      12
<PAGE>   14
         The Board  of Directors may  terminate or amend  the Directors Plan at
any time; provided,  however, that shareholder  approval will be required for
any increase in the  total number of shares  covered by the Directors  Plan or
any expansion  in the class  of persons eligible to receive options.

         3.      Federal Income  Tax Information.  The  following summary is
intended  only as a  general guide as to the  United States federal income tax
consequences under current  law with respect to participation  in the Directors
Plan, and  does not attempt to  describe all possible federal or other  tax
consequences of such participation.  Furthermore, the tax consequences of
options are complex and subject to change, and a taxpayer's particular
situation may be such that  some variation of the described rules  is
applicable.  Optionees should consult  their own tax advisors prior to  the
exercise of  any option and prior  to the disposition  of any shares  of Common
Stock  acquired upon  the exercise of  an option.

         Nonqualified stock options have no special tax status.   An optionee
recognizes no taxable income as the result of the  grant of such an option.
Generally, upon the  exercise of a nonqualified  stock option, the optionee
normally recognizes ordinary income in  the amount of the difference between
the option exercise price and the fair market value of the shares on the date
of exercise.

         Since  the optionees, as  directors of the  Bank, are subject  to
Section 16 of  the Exchange  Act, an optionee  will recognize ordinary income
on the date the  sale of the option shares at a profit would no  longer subject
the optionee to suit under Section 16(b)  of the Exchange Act (generally, six
months after  the date of exercise).  The amount  of ordinary income recognized
will be equal to the  difference between the option exercise  price and the
fair market value of  the shares on the  date six months after  the date of
exercise.  The  optionee may elect, however, pursuant to section 83(b) of the
Code, to have his or  her taxable income determined on the  exercise date by
filing an  election with the Internal Revenue Service not later than 30 days
after the date the option is exercised.

         Upon  the sale of shares acquired by the exercise of a nonqualified
stock option, any gain or loss, based on the difference between the sale price
and the fair market value of the shares on the date of recognition  of income,
will be taxed as capital gain or loss,  A capital gain or loss will be
long-term if the optionee's holding period is more than 12 months from the date
of recognition of income.

         No tax deduction is available to  the Bank with respect to the grant
of a nonqualified stock option or the sale  of the shares acquired by  the
exercise of  such an option.   The  Bank should be entitled  to a deduction
equal to  the amount of  ordinary income recognized  by the optionee as a
result of the exercise of the nonqualified stock option.


                         INDEPENDENT PUBLIC ACCOUNTANTS

         The Board  of Directors has  appointed KPMG Peat Marwick as
independent  public accountants  for the Bank's  fiscal year  ending December
31, 1992.  The appointment was made upon the recommendation of the Audit
Committee.

         KPMG Peat Marwick has served as the Bank's independent public
accountants since May 1989.  Audit services provided to the Bank by KPMG Peat
Marwick for 1991 consisted of the examination of the financial
statements of the Bank for the year ended December 31, 1991.

         Each professional service  provided by KPMG Peat Marwick 
either was approved  in advance or  was subsequently approved,  and the
possible effect on the auditors' independence was considered, by the Audit
Committee.

         A representative of KPMG Peat Marwick is expected  to be
present at  the Annual Meeting of  Shareholders with the opportunity  to make a
statement if he desires to do so and is expected to be available to respond to
appropriate questions.
