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

           The Registrant issued a press release dated June 6, 1996, announcing
the signing of a definitive agreement for a merger of equals of Registrant with
and into Mid-Peninsula Bancorp ("MPB") and that MPB will change its name to
Greater Bay Bancorp ("GBB") concurrent with closing of the merger. Cupertino
shareholders will receive .81522 of a share of GBB's common stock for each share
of Cupertino common stock in a tax-free exchange to be accounted for as a
"pooling-of-interests", resulting in approximately 49% ownership by Registrant
and approximately 51% ownership by MPB of the surviving corporation, Greater Bay
Bancorp.

           In connection with the merger, the Registrant and MPB granted
each other options to purchase up to 19% of the outstanding shares of each
other's common stock under certain circumstances in the event the transaction is
terminated. The merger is expected to be completed in the fourth quarter of
1996, subject to shareholder and regulatory approvals.

           The foregoing description is qualified by reference to the Amended
and Restated Agreement and Plan of Reorganization and Merger dated June 26, 1996
attached hereto as Exhibit 2.1 and press release dated June 6, 1996 attached
hereto as Exhibit 99.1, each incorporated herein by reference.

                             ---------------------
                AGREEMENT AND PLAN OF REORGANIZATION AND MERGER
                -----------------------------------------------


           THIS AMENDED AND RESTATED AGREEMENT AND PLAN OF REORGANIZATION AND
MERGER, dated as of June 26, 1996, ("Agreement"), amends and restates an
Agreement and Plan of Reorganization and Merger made and entered into as of June
5, 1996, by and between Mid-Peninsula Bancorp, a California corporation ("Mid-
Peninsula"), and Cupertino National Bancorp, a California corporation
("Cupertino").

           A.    The Boards of Directors of Mid-Peninsula and Cupertino deem it
advisable and in the best interests of Mid-Peninsula, Cupertino, their
subsidiaries and their respective shareholders that Mid-Peninsula and Cupertino
enter into a business combination, with the expectation that the resulting
company will combine the best elements of both Mid-Peninsula and Cupertino.
Pursuant to such business combination, Cupertino shall merge with and into Mid-
Peninsula (the "Merger") and Mid-Peninsula will change its name to Greater Bay
Bancorp ("Bancorp").  Following the Merger, Cupertino's subsidiary, Cupertino
National Bank & Trust ("CNB") and Mid-Peninsula's subsidiary, Mid-Peninsula Bank
("MPB"), shall be wholly-owned subsidiaries of Bancorp.

           B.    This Agreement and the Merger Agreement attached as Exhibit A
                                                                     ---------
and intended to be filed with the California Secretary of State (the "Merger
Agreement") have been approved by the Boards of Directors of Mid-Peninsula and
Cupertino, and the principal terms will be submitted for approval of the
shareholders of Cupertino and Mid-Peninsula at special meetings of their
respective shareholders.

           C.    The Merger is intended to qualify as a tax-free reorganization
within the meaning of Section 368 of the Internal Revenue Code of 1986, as
amended (the "IRC").

           D. Pursuant to the Merger, each Cupertino shareholder will receive,
in exchange for each share of Cupertino common stock ("Cupertino Share" or
"Cupertino Shares"), the number of shares of Bancorp common stock ("Bancorp
Share" or "Bancorp Shares") determined in accordance with the Conversion Ratio
as more fully set forth in this Agreement and in the Merger Agreement (the
"Conversion Ratio").

     NOW, THEREFORE, in consideration of the premises and the mutual agreements
contained herein and in the Merger Agreement, the parties hereto agree as
follows:


1.   THE MERGER.
     ---------- 

     1.1   Effective Date.  Subject to the terms and conditions of this
           --------------                                              
Agreement, the Merger shall become effective on the date ("Effective Date") and
at the time ("Effective 

                                       1
<PAGE>
 
Time of the Merger") an executed copy of the Merger Agreement has been filed
with the California Secretary of State.

     1.2   Effect of the Merger.  Subject to the terms and conditions of this
           --------------------                                              
Agreement, at the Effective Time of the Merger, Cupertino shall be merged with
and into Mid-Peninsula and Mid-Peninsula will change its name to Greater Bay
Bancorp ("Bancorp").  All assets, rights, privileges, immunities, powers,
franchises and interests of Cupertino in and to every type of property (real,
personal and mixed) and choses in action, as they exist as of the Effective
Date, including appointments, designations and nominations and all other rights
and interests as trustee, executor, administrator, registrar of stocks and
bonds, guardian of estate, assignee, receiver and in every other fiduciary
capacity, shall pass and be transferred to and vest in Bancorp by virtue of the
Merger at the Effective Time of the Merger without any deed, conveyance or other
transfer; the separate existence of Cupertino shall cease and the corporate
existence of Mid-Peninsula (with the change of its name as described above) as
Bancorp and as a California corporation shall continue unaffected and unimpaired
by the Merger; and Bancorp shall be deemed to be the same entity as each of
Cupertino and Mid-Peninsula and shall be subject to all of their duties and
liabilities of every kind and description.  Bancorp shall be responsible and
liable for all the liabilities and obligations of each of Mid-Peninsula and
Cupertino; and any claim existing or action or proceeding pending by or against
Mid-Peninsula or Cupertino may be prosecuted as if the Merger had not taken
place, or Bancorp may be substituted in its place.  Neither the rights of
creditors nor any liens upon the property of either Mid-Peninsula or Cupertino
shall be impaired by reason of the Merger.


2.   CONVERSION AND CANCELLATION OF SHARES.
     ------------------------------------- 

     2.1   Conversion of Cupertino Shares.  At the Effective Time of the Merger,
           ------------------------------                                       
by virtue of the Merger and without any action on the part of any holder of
Cupertino Shares, subject to Section 2.2, 2.3 and 2.5 of this Agreement, each
outstanding Cupertino Share (other than any shares as to which dissenters'
rights have been perfected) shall be converted into the right to receive .81522
Bancorp Shares (the "Conversion Ratio").

     2.2   Fractional Shares.  Notwithstanding any other provision hereof, no
           -----------------                                                 
fractional shares of Bancorp Shares shall be issued to holders of Cupertino
Shares.  In lieu thereof, each such holder entitled to a fraction of a Bancorp
Share shall receive, at the time of surrender of the certificate or certificates
representing such holder's Cupertino Shares, an amount in cash equal to the
market value per share of the Mid-Peninsula common stock ("Mid-Peninsula
Shares"), calculated (to the nearest hundredth) by taking the average of the
closing bid and asked prices quoted by each brokerage firm then acting as a
market maker of Mid-Peninsula Shares, for each of the twenty (20) consecutive
trading days up to and including the last business day of the month-end
immediately preceding the Closing Date (the "Determination Date") (whether or
not there were any trades in Mid-Peninsula Shares on such days), multiplied by
the fraction of a Bancorp Share to which such holder otherwise 

                                       2
<PAGE>
 
would be entitled. No such holder shall be entitled to dividends, voting rights,
interest on the value of, or any other rights in respect of a fractional share.

     2.3   Surrender of Cupertino Shares.
           ----------------------------- 

           a.    Prior to the Effective Date, Mid-Peninsula shall appoint U.S.
Stock Transfer Corporation or its successor, or any other bank or trust company
(having capital of at least $50 million) mutually acceptable to Cupertino and
Mid-Peninsula, as exchange agent (the "Exchange Agent") for the purpose of
exchanging certificates representing Cupertino Shares and at and after the
Effective Time of the Merger, Bancorp shall issue and deliver to the Exchange
Agent such number of certificates representing Bancorp Shares and cash for
payment of fractional shares, as shall be required to be delivered to holders of
Cupertino Shares pursuant to Article 2 of the Merger Agreement. As soon as
practicable after the Effective Time of the Merger, each holder of Cupertino
Shares converted pursuant to Section 2.1, upon surrender to the Exchange Agent
of one or more certificates for such Cupertino Shares for cancellation, will be
entitled to receive a certificate or certificates representing the number of
Bancorp Shares determined in accordance with Section 2.1 and a payment in cash
with respect to fractional shares, if any, determined in accordance with Section
2.2.

           b.    No dividends or other distributions of any kind which are
declared payable to shareholders of record of the Bancorp Shares after the
Effective Date will be paid to persons entitled to receive such certificates for
Bancorp Shares until such persons surrender their certificates representing
Cupertino Shares. Upon surrender of such certificates representing Cupertino
Shares, the holder thereof shall be paid, without interest, any dividends or
other distributions with respect to the Bancorp Shares as to which the record
date and payment date occurred on or after the Effective Date and on or before
the date of surrender.

           c.    If any certificate for Bancorp Shares is to be issued in a name
other than that in which the certificate for Cupertino Shares surrendered in
exchange therefor is registered, any transfer costs or expenses (except taxes)
required by reason of the issuance of certificates for such Bancorp Shares in a
name other than the registered holder of the certificate surrendered shall be
paid by Bancorp.

           d.    All dividends or distributions, and any cash to be paid
pursuant to Section 2.2 in lieu of fractional shares, if held by the Exchange
Agent for payment or delivery to the holders of unsurrendered certificates
representing Cupertino Shares and unclaimed at the end of one year from the
Effective Date, shall (together with any interest earned thereon) at such time
be paid or redelivered by the Exchange Agent to Bancorp, and after such time any
holder of a certificate representing Cupertino Shares who has not surrendered
such certificate to the Exchange Agent shall, subject to applicable law, look as
a general creditor only to Bancorp for payment or delivery of such dividends or
distributions or cash, as the case may be.

                                       3
<PAGE>
 
     2.4   No Further Transfers of Cupertino Shares.  At the Effective Time of
           ----------------------------------------                           
the Merger, the stock transfer books of Cupertino shall be closed and no
transfer of Cupertino Shares theretofore outstanding shall thereafter be made.

     2.5   Adjustments. If, between the date of this Agreement and the Effective
           -----------
Date, the outstanding shares of Mid-Peninsula Shares or Cupertino Shares shall
have been changed into a different number of shares or a different class by
reason of any reclassification, recapitalization, split-up, combination,
exchange of shares or readjustment, or a stock dividend thereon shall be
declared with a record date within such period, the number of Bancorp Shares to
be issued and delivered in the Merger in exchange for each outstanding Cupertino
Share shall be correspondingly adjusted.

     2.6   Treatment of Stock Options.
           -------------------------- 

           a.    Each person holding one or more options to purchase Cupertino
Shares ("Cupertino Option" or "Cupertino Options") pursuant to Cupertino's (i)
1985 Stock Option Plan, (ii) 1986 Non-Qualified Stock Option Plan, (iii) 1989
Non-Qualified Stock Option Plan, or (iv) 1995 Stock Option Plan, each as amended
to date ("Cupertino Stock Option Plans") shall have the right, in his or her
discretion, to either:

                 (i) Exercise any vested portion (including any portion vested
as a result of the Merger) of the Cupertino option to acquire Cupertino Shares
prior to the Effective Date; or

                 (ii) As of the Effective Time of the Merger, surrender the
Cupertino Option agreement to Mid-Peninsula, in which event such person will be
entitled to receive a substitute option ("Substitute Option") exercisable for
(a) the number of Bancorp Shares equal to the number of Cupertino Shares for
which such person held Cupertino Options multiplied by the Conversion Ratio and
rounded up to the nearest whole share, and (b) the exercise price for the shares
subject to said options shall be adjusted by dividing the pre-Merger exercise
price for such Cupertino Options by the Conversion Ratio, rounded to the nearest
penny.

           b.    The Substitute Options to be received in exchange for Cupertino
Options shall be, to the greatest extent practicable, vested to the same extent
as before the Merger, shall continue to vest on the same vesting schedule as
provided under the original applicable Cupertino Option agreement, shall be
exercisable as provided in the original applicable Cupertino Option agreement
and shall otherwise preserve the characteristics, terms and conditions of the
original Cupertino Option to the greatest extent possible, subject to the
requirements of law and the rules and regulations of the California Commissioner
of Corporations.

Directors of each party to its shareholders, prior to the Effective Time of the
Merger, neither party shall effect or agree to effect or enter into a
transaction or series of transactions with one or more third persons, groups or
entities providing for the acquisition of all or a substantial part of either
party or their respective subsidiaries, whether by way of merger, exchange of

to acquire any of its own capital stock or the capital stock or asset (except in
a fiduciary capacity or in the Ordinary Course of Business) of any other entity,
or commence any proceedings for winding up and dissolution affecting either of

                 (ii)  Subject to the continuing fiduciary duty of the Board of

shareholders, subject to the provisions of this Agreement including, without
limitation, Section 12e(ii) and the rights accorded a party thereunder which
shall remain in effect, such duty to act or to refrain from doing any act shall
be excused and such failure to act or refrain from doing any act shall not (a)

action asserting any liability against any member of the Board of Directors of

receive credit for his or her years of service with Mid-Peninsula or Cupertino,
as applicable, for purposes of eligibility and vesting under Bancorp's employee
benefit plans; provided, further, that each Transferred Employee who elects
coverage under Bancorp's indemnity health plan within thirty (30) days after

with the other in its reasonable requests for information. Each party shall

compliance with all applicable securities laws. Otherwise, there are no
outstanding (i) options, agreements, calls or commitments of any character which

dispose of, or to purchase, redeem or otherwise acquire, any Cupertino common
stock or any other equity security of Cupertino, or (ii) warrants or options
relating to, rights to acquire, or debt or equity securities convertible into,

                 --------------------------

                 ----------------------------------------
statement or other document provided or to be provided to Mid-Peninsula as
required by Section 3.3(j) hereof, as of the date of such document, contained,
or as to documents to be delivered after the date hereof, will contain, any
untrue statement of a material fact, or, at the date thereof, omitted or will
omit to state a material fact necessary in order to make the statements
contained therein, in light of the circumstances under which such statements
were or will be made, not misleading; provided, however, that information as of
a later date shall be deemed to modify contrary information as of any earlier

CNB has received any notification, formally or informally, from any agency or
department of any federal, state or local government or any regulatory authority
or the staff thereof (i) asserting that it is not in compliance with any of the
statutes, regulations or ordinances which such government or regulatory
authority enforces, or (ii) threatening to revoke any license, franchise, permit
or government authorization. Cupertino and CNB have paid all assessments made or
imposed by any government agency. Cupertino has delivered to Mid-Peninsula
copies of all annual management letters and opinions, and has made available to
Mid-Peninsula for inspection all reviews, correspondence and other documents in
the files of Cupertino prepared by Coopers & Lybrand LLP or any other certified
public accountant engaged by Cupertino and delivered to Cupertino since December

be, maintained in all material respects in accordance with all applicable legal
and accounting requirements sufficient to insure that all transactions reflected
therein are, in all material respects, executed in accordance with management's
general or specific authorization and recorded in conformity with generally
accepted accounting principles at the time in effect. The data processing
equipment, data transmission equipment, related peripheral equipment and
software used by Cupertino in the operation of its business to generate and
retrieve its financial records are adequate for the current needs of Cupertino.

all taxes, fees and other government charges, including any interest and
penalties thereon, when they have become due, except those that are being

Peninsula. Cupertino and/or CNB has not been requested to give nor has it given
any currently effective waivers extending the statutory period of limitation
applicable to any tax return required to be filed by it for any period. There
are no claims pending against Cupertino and/or CNB for any alleged deficiency in
the payment of any taxes, and Cupertino does not know of any pending or
threatened audits, investigations or claims for unpaid taxes or relating to any
liability in respect of any taxes. There have been no events, including a change
in ownership, that would result in a reappraisal and establishment of a new 
base-year full value for purposes of applicable provisions of the California
Constitution, of any real property owned in whole or in part by Cupertino or CNB
or to the best of Cupertino's knowledge, of any real property leased by
Cupertino or CNB.

           h.    Material Adverse Change. Except as heretofore disclosed in
                 -----------------------
writing by Cupertino to Mid-Peninsula, since December 31, 1995, there has been
(i) no material adverse change in the business, assets, licenses, permits,
franchises, results of operations or financial condition of Cupertino or CNB
(whether or not in the Ordinary Course of Business), (ii) no change in any of
the assets, licenses, permits or franchises of Cupertino or CNB that has had or
can reasonably be expected to have a material adverse effect on any of the items
listed in clause (h)(i) above, (iii) no damage, destruction, or other casualty
loss (whether or not covered by insurance) that has had or can reasonably be
expected to have a material adverse effect on any of the items listed in clause
(h)(i) above, (iv) no amendment, modification, or termination of any existing,
or entering into of any new, contract, agreement, plan, lease, license, permit
or franchise that is material to the business, financial condition, assets,
liabilities or operations of Cupertino and CNB, except in the Ordinary Course of
Business; and (v) no disposition by Cupertino or CNB of one or more assets that,
individually or in the aggregate, are material to Cupertino or CNB, except sales
of assets in the Ordinary Course of Business.

           i.    No Undisclosed Liabilities. Except for items for which reserves
                 --------------------------
have been established in the unaudited balance sheets of Cupertino as of March
31, 1996, Cupertino has not incurred or discharged, and is not legally obligated
with respect to, any indebtedness, liability (including, without limitation, a
liability arising out of an indemnification, guarantee, hold harmless or similar
arrangement) or obligation (accrued or contingent, whether due or to become due,
and whether or not subordinated to the claims of its general creditors), other
than as a result of operations in the Ordinary Course of Business after such
date. No agreement pursuant to which any loans or other assets have been or will
be sold by Cupertino or CNB entitles the buyer of such loans or other assets,
unless there is a material breach of a representation or covenant by Cupertino
or CNB, to cause Cupertino or CNB to repurchase such loan or other asset or to
pursue any other form of recourse against Cupertino or CNB. Neither Cupertino
nor CNB has knowingly made or shall make any representation or covenant in any
such agreement that contained or shall contain any untrue statement of a
material fact or omitted or shall omit to state a material fact necessary in
order to make the statements contained therein, in light of the circumstances
under which such representations and/or covenants were made or shall be made,
not misleading. No cash, stock or other dividend or any other distribution with
respect to the Cupertino Shares has been declared, set aside or paid, nor have
any of the Cupertino Shares been purchased, redeemed or otherwise acquired,
directly or indirectly, by Cupertino since December 31, 1995.

           j.    Properties and Leases.
                 --------------------- 

                 (i) Cupertino and CNB have good and marketable title, free and
clear of all liens and encumbrances and the right of possession, subject to
existing leaseholds, to all real properties and good title, free and clear of
all liens and encumbrances, to all other property and assets, tangible and
intangible, reflected in the Cupertino balance sheet as of March 31, 1996
(except property held as lessee under leases disclosed in writing prior to the
date hereof and except personal property sold or otherwise disposed of since
March 31, 1996, in the Ordinary Course of Business), except for (a) liens for
taxes or assessments not delinquent, (b) such other liens and encumbrances and
imperfections of title as do not materially affect the value of such property as
reflected in the Cupertino balance sheet as of March 31, 1996, or as currently
shown on the books and records of Cupertino and which do not interfere with or
impair its present and continued use, or (c) exceptions disclosed in title
reports and preliminary title reports, copies of which have been provided to 
Mid-Peninsula. All tangible properties of Cupertino and CNB conform in all 
material respects with all applicable ordinances, regulations and zoning laws. 
All tangible properties of Cupertino and CNB are in a good state of maintenance
and repair and are adequate for the current business of Cupertino and CNB. No
properties of Cupertino and CNB, and, to the best of Cupertino's knowledge, no
properties in which Cupertino or CNB holds a collateral or contingent interest
or purchase option, are the subject of any pending or threatened investigation,
claim or proceeding relating to the use, storage or disposal on such property of
or contamination of such property by any toxic or hazardous waste material or
substance. To the best of Cupertino's knowledge, neither Cupertino nor CNB owns,
possesses or has a collateral or contingent interest or purchase option in any
properties or other assets which contain or have located within or thereon any
hazardous or toxic waste material or substance unless the location of such
hazardous or toxic waste material or other substance or its use thereon conforms
in all material respects with all federal, state and local laws, rules,
regulations or other provisions regulating the discharge of materials into the
environment. As to any real property not owned or leased by Cupertino or CNB and
held as security for a loan or in which Cupertino or CNB otherwise has an
interest, neither Cupertino or CNB has controlled, directed or participated in
the operation or management of any such real property or any facilities or
enterprise conducted thereon, such that it has become an owner or operator of
such real property under applicable environmental laws.

                 (ii) All properties held by Cupertino or CNB under leases are
held under valid, binding and enforceable leases, with such exceptions as are
not material and do not interfere with the conduct of the business of Cupertino
or CNB, and Cupertino and CNB enjoy quiet and peaceful possession of such leased
property. Neither Cupertino nor CNB is in material default in any respect under
any material lease, agreement or obligation regarding its properties to which it
is a party or by which it is bound.

                 (iii) Except as disclosed to Mid-Peninsula in writing, all of
Cupertino's and CNB's rights and obligations under the leases referred to in
Section 4(j)(ii) above do not require the consent of any other party to the
transaction contemplated by this Agreement and 

                                      20
<PAGE>
 
the Merger Agreement. Where required, Cupertino and CNB shall obtain, prior to
the Effective Date, the consent of such parties to such transaction.

           k.    Material Contracts. Except as previously disclosed to Mid-
                 ------------------
Peninsula in writing and excluding loans, lines of credit, loan commitments or
letters of credit to which Cupertino or CNB is a party, neither Cupertino nor
CNB is a party to or bound by any contract or other agreement made in the
Ordinary Course of Business which involves aggregate future payments by or to
Cupertino or CNB of more than $20,000 and which is made for a fixed period
expiring more than one year from the date hereof, and neither Cupertino nor CNB
is a party to or bound by any agreement not made in the Ordinary Course of
Business which is to be performed at or after the date hereof. Each of the
contracts and agreements disclosed to Mid-Peninsula pursuant to this Section
4(k) is a legal and binding obligation (subject to applicable bankruptcy,
insolvency and similar laws affecting creditors' rights generally and subject,
as to enforceability, to equitable principles of general applicability), and no
breach or default (and no condition which, with notice or passage of time, or
both, could become a breach or default) exists with respect thereto.

           l.    Classified Loans. Except as previously disclosed to Mid-
                 ----------------
Peninsula in writing, there are no loans presently owned by Cupertino or CNB
that have been classified by Cupertino or CNB management or Cupertino or CNB
internal policy or procedure, any outside review examiner, accountant or any
bank regulatory authority as "Other Loans Specially Mentioned," "Special
Mention," "Substandard," "Doubtful," or "Loss" or classified using categories or
words with similar import and all loans or portions thereof so classified shall
have been charged off to the extent required. Cupertino and CNB regularly review
and appropriately classify their loans in accordance with all applicable legal
and regulatory requirements and generally accepted banking practices. All loans
and investments of Cupertino and CNB are legal, valid and binding obligations
enforceable in accordance with their respective terms and are not subject to any
setoffs, counterclaims or disputes (subject to applicable bankruptcy, insolvency
and similar laws affecting creditors' rights generally and subject, as to
enforceability, to equitable principles of general applicability), except as
disclosed to Mid-Peninsula in writing or reserved for in the unaudited balance
sheet of Cupertino as of March 31, 1996, and were duly authorized under and made
in compliance with applicable federal and state laws and regulations. Neither
Cupertino nor CNB has any extensions of credit, investments, guarantees,
indemnification agreements or commitments for the same (including without
limitation commitments to issue letters of credit, to create acceptances, or to
repurchase securities, federal funds or other assets) other than those
documented on the books and records of Cupertino and CNB.

           m.    Restrictions on Investments. Except for pledges to secure
                 ---------------------------
public and trust deposits and repurchase agreements in the Ordinary Course of
Business, none of the investments reflected in the Cupertino balance sheet as of
March 31, 1996, and none of the investments made by Cupertino or CNB since March
31, 1996, is subject to any restriction, whether contractual or statutory, which
materially impairs the ability of Cupertino or CNB to freely dispose of such
investment at any time.

proportional accruals for partial periods) have been made in accordance with
generally accepted accounting principles consistently applied on a reasonable
basis; and

                 (iii) Cupertino has disclosed in writing to Mid-Peninsula the
names of each director, officer and employee of Cupertino and CNB; and

                 (iv) The Employee Plans have been administered where required
in substantial compliance with ERISA, the IRC and the terms of such Employee
Plans, and there is no pending or threatened litigation relating to any such
Employee Plan; and

                 (v) Cupertino and CNB have not offered in the past health
benefits for retired employees; and

                 (vi) Each Employee Plan is in full force and effect, and
neither Cupertino, CNB nor any other party is in material default under any of
them, and there have been no claims of default and there are no facts or
conditions which if continued, or on notice, will result in a material default
under any Employee Plans; and

                 (vii) Cupertino has provided to Mid-Peninsula a list of all

the amount of compensation due any such employee or officer.

           o.    Collective Bargaining and Employment Agreements. Except as
                 -----------------------------------------------
provided in this Agreement or as previously disclosed to Mid-Peninsula in
writing, neither Cupertino nor CNB has any union or collective bargaining or
written employment agreements, contracts or other agreements with any labor
organization or with any member of management, or any management or consultation
agreement not terminable at will by Cupertino or CNB without liability and no
such contract or agreement has been requested by, or is under discussion by
management with, any group of employees, any member of management or any other
person. There are no material controversies pending between Cupertino or CNB and
any current or former employees, and to the best of Cupertino's knowledge, there
are no efforts presently being made by any labor union seeking to organize any
of such employees.

           p.    Compensation of Officers and Employees.  Except as previously
                 --------------------------------------                       
disclosed to Mid-Peninsula in writing, (i) no officer or employee of Cupertino
or CNB is receiving aggregate direct remuneration at a rate exceeding $60,000
per annum, and (ii) the consummation of the transactions contemplated by this
Agreement and the Merger Agreement will not (either alone or upon the occurrence
of any additional or further acts or events) result in any payment (whether of
severance pay or otherwise) becoming due from Cupertino, CNB or Mid-Peninsula to
any employee of Cupertino or CNB.

           q.    Legal Actions and Proceedings. Except as previously disclosed
                 -----------------------------
to Mid-Peninsula in writing, neither Cupertino nor CNB is a party to, or so far
as known to either of them, threatened with, and to Cupertino's knowledge, there
is no reasonable basis for, any legal action or other proceeding or
investigation before any court, any arbitrator of any kind or any government
agency, and neither Cupertino nor CNB is subject to any potential adverse claim,
the outcome of which could involve the payment or receipt by Cupertino or CNB of
any amount in excess of $50,000, unless an insurer has agreed to defend against
and pay the amount of any resulting liability without reservation, or, if any
such legal action, proceeding, investigation or claim will not involve the
payment by Cupertino or CNB of a monetary amount, which could materially
adversely affect Cupertino or CNB or their business or property or the
transactions contemplated hereby. Cupertino has no knowledge of any pending or
threatened claims or charges under the Community Reinvestment Act, before the
Equal Employment Opportunity Commission, the California Department of Fair
Housing & Economic Development, the California Unemployment Appeals Board, or
any federal or state human relations commission or agency. There is no labor
dispute, strike, slow-down or stoppage pending or, to the best of the knowledge
of Cupertino, threatened against Cupertino or CNB.

           r.    Execution and Delivery of the Agreement.
                 --------------------------------------- 

                 (i) The execution and delivery of this Agreement and the Merger
Agreement have been duly authorized by the Board of Directors of Cupertino and,
when the principal terms of the Merger, this Agreement and the Merger Agreement
have been duly approved by the affirmative vote of the holders of a majority of
the outstanding Cupertino 

                                      23
<PAGE>
 
Shares at a meeting of shareholders duly called and held, the Merger, this
Agreement and the Merger Agreement will be duly and validly authorized by all
necessary corporate action on the part of Cupertino.

                 (ii) This Agreement has been duly executed and delivered by
Cupertino and (assuming due execution and delivery by Mid-Peninsula)
constitutes, and the Merger Agreement, upon its execution and delivery by
Cupertino (and assuming due execution and delivery by Mid-Peninsula) will
constitute, a legal and binding obligation of Cupertino in accordance with its
terms.

                 (iii) The execution and delivery by Cupertino of this Agreement
and the Merger Agreement and the consummation of the transactions herein and
therein contemplated (a) do not violate any provision of the Articles of
Incorporation or Articles of Association or Bylaws of Cupertino or CNB,
respectively, or violate in any material respect any provision of federal or
state law or any government rule or regulation (assuming (1) receipt of the
Government Approvals, (2) receipt of the requisite Cupertino shareholder
approval referred to in Section 4(r)(i) hereof, (3) due registration of the
Bancorp Shares under the 1933 Act, and (4) receipt of appropriate permits or
approvals under state securities or "blue sky" laws, and (b) do not require any
consent of any person under, conflict in any material respect with or result in
a material breach of, or accelerate the performance required by any of the terms
of, any material debt instrument, lease, license, covenant, agreement or
understanding to which Cupertino or CNB is a party or by which it is bound or
any order, ruling, decree, judgment, arbitration award or stipulation to which
Cupertino or CNB is subject, or constitute a material default thereunder or
result in the creation of any lien, claim, security interest, encumbrance,
charge, restriction or right of any third party of any kind whatsoever upon any
of the properties or assets of Cupertino or CNB.

           s.    Retention of Broker or Consultant.  No broker, agent, finder,
                 ---------------------------------                            
consultant or other party (other than legal, compliance, loan auditors and
accounting advisors) has been retained by Cupertino or CNB or is entitled to be
paid based upon any agreements, arrangements or understandings made by Cupertino
or CNB in connection with any of the transactions contemplated by this Agreement
or the Merger Agreement, except that Cupertino has engaged the firm of Sutro &
Co. Incorporated to render an opinion regarding the fairness of the
consideration to be received by Cupertino shareholders in the Merger.  Cupertino
has provided Mid-Peninsula with a true and accurate copy of its agreement(s)
with Sutro & Co. Incorporated.

           t.    Insurance.  Cupertino and CNB are and continuously since their
                 ---------                                                     
inception have been, insured with reputable insurers against all risks normally
insured against by bank holding companies and banks, and all of the insurance
policies and bonds maintained by Cupertino and CNB are in full force and effect,
Cupertino and CNB are not in default thereunder and all material claims
thereunder have been filed in due and timely fashion.  In the best judgment of
the management of Cupertino and CNB, such insurance coverage is adequate for
Cupertino and CNB.  Since December 31, 1995, there has not been any damage 

                                      24
<PAGE>
 
to, destruction of, or loss of any assets of Cupertino or CNB not covered by
insurance that could materially and adversely affect the business, financial
condition, properties, assets or results of operations of Cupertino or CNB.

           u.    Loan Loss Reserves. The allowance for loan losses in the
                 ------------------
Cupertino balance sheets dated December 31, 1995, March 31, 1996, and as of the
Determination Date are and will be adequate in all material respects under the
requirements of all applicable state and federal laws and regulations to provide
for possible loan losses on outstanding loans, net of recoveries. Cupertino has
disclosed to Mid-Peninsula in writing prior to the date hereof, and will
promptly inform Mid-Peninsula of the amounts of all loans, leases, other
extensions of credit or commitments, or other interest-bearing assets of
Cupertino and CNB, that have been classified as of the date hereof or hereafter
by Cupertino or CNB management or Cupertino or CNB internal policy or procedure,
any outside review examiner, accountant or any bank regulatory authority as
"Other Loans Specially Mentioned," "Special Mention," "Substandard," "Doubtful,"
or "Loss" or classified using categories or words with similar import in the
case of loans (or that would have been so classified, in the case of other
interest-bearing assets, had they been loans). Notwithstanding the above,
Cupertino shall be under no obligation to disclose to Mid-Peninsula any such
classification by any bank regulatory authority where such disclosure would
violate any obligation of confidentiality of Cupertino or CNB imposed by such
bank regulatory authority. Cupertino has furnished and will continue to furnish
to Mid-Peninsula true and accurate information concerning the loan portfolio of
Cupertino and CNB, and no material information with respect to the loan
portfolio has been or will be withheld from Mid-Peninsula.

           v.    Transactions With Affiliates.  Except in the Ordinary Course of
                 ----------------------------
Business, neither Cupertino nor CNB has extended credit, committed itself to
extend credit, or transferred any asset to or assumed or guaranteed any
liability of the employees or directors of Cupertino or CNB, or to any spouse or
child of any of them, or to any of their "affiliates" or "associates" as such
terms are defined in Rule 405 under the 1933 Act.  Neither Cupertino nor CNB has
entered into any other transactions with the employees or directors of Cupertino
or CNB or any spouse or child of any of them, or any of their affiliates or
associates, except as disclosed in writing to Mid-Peninsula.  Any such
transactions have been on terms no less favorable to Cupertino and CNB than
those which would prevail in an arms-length transaction with an independent
third party.  Neither Cupertino nor CNB has violated any applicable regulation
of any government agency or regulatory authority having jurisdiction over
Cupertino or CNB in connection with any such transactions described in this
subsection v.

           w.    Information in Mid-Peninsula Registration Statement. The
                 ---------------------------------------------------

Peninsula for or on behalf of Cupertino for inclusion in the Mid-Peninsula
Registration Statement and the Joint Proxy Statement/Prospectus, or in the

periods covered by such statements. Cupertino shall promptly advise Mid-
Peninsula in writing if prior to the Effective Time of the Merger Cupertino
shall obtain knowledge of any facts that would make it necessary to amend or
supplement the Mid-Peninsula Registration Statement, the Joint Proxy
Statement/Prospectus or any Application, in order to make the statements therein
not misleading or to comply with applicable law or regulation.

Covenants and Agreements.  Each representation, warranty, covenant and agreement

section of such representation or warranty and delivered on or before the
Document Delivery Date, and upon such delivery it shall be deemed made on and as
of the date of delivery), the Closing Date and the Effective Time of the Merger.
No representation or warranty by Cupertino, and no statement by Cupertino in any
certificate, agreement, schedule or other document furnished or to be furnished
in connection with the transactions contemplated by this Agreement or the Merger
Agreement, was or will be inaccurate, incomplete or incorrect in any material
respect as of the date furnished or contains or will contain any untrue

standing under California law and is a registered bank holding company under the

Agreement and to carry out all of the terms and provisions hereof and thereof to
be carried out by it, (iii) MPB holds a currently valid license issued by the
Superintendent to engage in the commercial banking business in California at the

neither Mid-Peninsula nor MPB is subject to any directive, resolution,
memorandum of understanding or order of the FDIC, FRB, Superintendent or any
other regulatory authority having jurisdiction over its business or any of its
assets or properties. Neither the scope of the business of Mid-Peninsula or MPB
nor the location of their properties requires either of them to be licensed to
do business in any jurisdiction other than the State of California. MPB's
deposits are insured by the FDIC to the maximum extent permitted by applicable
law and regulation.

           b.    Articles, Bylaws, Books and Records. The copies of the Articles

the date hereof. The minute books of Mid-Peninsula and MPB made available to
Cupertino contain a complete and accurate record of all meetings of Mid-
Peninsula's and MPB's respective Boards of Directors (and committees thereof)

federal and state laws (including but not limited to the Bank Secrecy Act),
rules and regulations relating to the offer, sale or issuance of securities, and
the operation of a commercial bank, other than where such noncompliance or

business of Mid-Peninsula or MPB or is not likely to otherwise have a material
adverse effect on Mid-Peninsula and MPB taken as a whole, (iii) have not failed
to file with the proper federal, state, local or other authorities any material
report or other document required to be filed, and (iv) have all approvals,
authorizations, consents, licenses, clearances and orders of, and have currently

                 --------------

Peninsula common stock, at a weighted average exercise price of $12.84 per
share, issued pursuant to the Mid-Peninsula Stock Option Plan.  Said options
were issued and, upon issuance in accordance with the terms of the outstanding
options said shares shall be issued, in compliance with all applicable
securities laws.  Otherwise, there are no outstanding (i) options, agreements,
calls or commitments of any character which would obligate Mid-Peninsula to
issue, sell, pledge, assign or otherwise encumber or dispose of, or to purchase,
redeem or otherwise acquire, any Bancorp common stock or any other equity
security of Mid-Peninsula, or (ii) warrants or options relating to, rights to

upon the Intellectual Property Rights of any other person or entity. No claim 
is pending or threatened by any person or entity against or otherwise affecting

best of its knowledge, there is no valid basis for any such claim.

           f.    Financial Statements, Regulatory Reports. No financial
                 ---------------------------------------- 
statement or other document provided or to be provided to Cupertino as required
by Section 3.3(j) hereof, as of the date of such document, contained, or as to
documents to be delivered after the date hereof, will contain, any untrue
statement of a material fact, or, at the date thereof, omitted or will omit to
state a material fact necessary in order to make the statements contained

filed by them with the FDIC, FRB, Superintendent, the Commission and any other
government agency or regulatory authority having jurisdiction over their
business, assets or properties. All such reports conform in all material
respects with the requirements promulgated by such government agencies and
regulatory authorities. All compliance or corrective action relating to Mid-
Peninsula and MPB required by government agencies and regulatory authorities
having jurisdiction over Mid-Peninsula or MPB has been taken. Except as

statutes, regulations or ordinances which such government or regulatory
authority enforces, or (b) threatening to revoke any license, franchise, permit
or government authorization. Mid-Peninsula and MPB 

                                      28

correspondence and other documents in the files of Mid-Peninsula prepared by
KPMG Peat Marwick LLP or any other certified public accountant engaged by Mid-
Peninsula and delivered to Mid-Peninsula since December 31, 1990. The financial
records of Mid-Peninsula have been, and are being and shall be, maintained in
all material respects in accordance with all applicable legal and accounting
requirements sufficient to insure that all transactions reflected therein are,
in all material respects, executed in accordance with management's general or
specific authorization and recorded in conformity with generally accepted
accounting principles at the time in effect. The data processing equipment, data
transmission equipment, related peripheral equipment and software used by Mid-

returns, other withholding tax returns and Federal Unemployment Tax Returns, and
all other reports or other information required or requested to be filed by
either of them, and each such return, report or other information was, when

and penalties thereon, when they have become due, except those that are being
contested in good faith, which contested matters have been disclosed to
Cupertino. Mid-Peninsula and/or MPB has not been requested to give nor has it
given any currently effective waivers extending the statutory period of
limitation applicable to any tax return required to be filed by it for any
period. There are no claims pending against Mid-Peninsula and/or MPB for any
alleged deficiency in the payment of any taxes, and Mid-Peninsula does not know
of any pending or threatened audits, investigations or claims for unpaid taxes
or relating to any liability in respect of any taxes. There have been no events,
including a change in ownership, that would result in a reappraisal and
establishment of a new base-year full value for purposes of applicable
provisions of the California Constitution, of any real property owned in whole
or in part by Mid-Peninsula or MPB or to the best of Mid-Peninsula's knowledge,
of any real property leased by Mid-Peninsula or MPB.

of all its tax returns with respect to taxes payable to the United States of
America and the State of California for the fiscal years ended December 31,

           h.    Material Adverse Change. Except as heretofore disclosed in
                 -----------------------
writing by Mid-Peninsula to Cupertino, since December 31, 1995, there has been
(i) no material adverse change in the business, assets, licenses, permits,
franchises, results of operations or financial condition of Mid-Peninsula or MPB
(whether or not in the Ordinary Course of Business), (ii) no change in any of
the assets, licenses, permits or franchises of Mid-Peninsula or MPB that has had
or can reasonably be expected to have a material adverse effect on any of the
items listed in clause (h)(i) above, (iii) no damage, destruction, or other
casualty loss (whether or not covered by insurance) that has had or can
reasonably be expected to have a material adverse effect on any of the items
listed in clause (h)(i) above, (iv) no amendment, modification, or termination
of any existing, or entering into of any new, contract, agreement, plan, lease,
license, permit or franchise that is material to the business, financial
condition, assets, liabilities or operations of Mid-Peninsula and MPB, except in
the Ordinary Course of Business, and (v) no disposition by Mid-Peninsula or MPB
of one or more assets that, individually or in the aggregate, are material to
Mid-Peninsula or MPB, except sales of assets in the Ordinary Course of Business.

           i.    No Undisclosed Liabilities. Except for items for which reserves
                 --------------------------
have been established in the unaudited balance sheets of Mid-Peninsula as of
March 31, 1996, Mid-Peninsula has not incurred or discharged, and is not legally
obligated with respect to, any indebtedness, liability (including, without
limitation, a liability arising out of an indemnification, guarantee, hold
harmless or similar arrangement) or obligation (accrued or contingent, whether
due or to become due, and whether or not subordinated to the claims of its
general creditors), other than as a result of operations in the Ordinary Course
of Business after such date. No agreement pursuant to which any loans or other
assets have been or will be sold by Mid-Peninsula or MPB entitles the buyer of
such loans or other assets, unless there is a material breach of a
representation or covenant by Mid-Peninsula or MPB, to cause Mid-Peninsula or
MPB to repurchase such loan or other asset or to pursue any other form of
recourse against Mid-Peninsula or MPB. Neither Mid-Peninsula nor MPB has
knowingly made or shall make any representation or covenant in any such
agreement that contained or shall contain any untrue statement of a material
fact or omitted or shall omit to state a material fact necessary in order to
make the statements contained therein, in light of the circumstances under which
such representations and/or covenants were made or shall be made, not
misleading. No cash, stock or other dividend or any other distribution with
respect to the Bancorp Shares has been declared, set aside or paid, nor have any
of the Bancorp Shares been purchased, redeemed or otherwise acquired, directly
or indirectly, by Mid-Peninsula since May 22, 1996.

           j.    Properties and Leases.
                 --------------------- 

                 (i) Mid-Peninsula and MPB have good and marketable title, free
and clear of all liens and encumbrances and the right of possession, subject to
existing leaseholds, to all real properties and good title, free and clear of
all liens and encumbrances, to all other property and assets, tangible and
intangible, reflected in the Mid-Peninsula balance sheet as of March 31, 1996
(except property held as lessee under leases disclosed in writing prior to 

                                      30
<PAGE>
 
the date hereof and except personal property sold or otherwise disposed of since
March 31, 1996, in the Ordinary Course of Business), except for (a) liens for
taxes or assessments not delinquent, (b) such other liens and encumbrances and
imperfections of title as do not materially affect the value of such property as
reflected in the Mid-Peninsula balance sheet as of March 31, 1996, or as
currently shown on the books and records of Mid-Peninsula and which do not
interfere with or impair its present and continued use, or (c) exceptions
disclosed in title reports and preliminary title reports, copies of which have
been provided to Cupertino. All tangible properties of Mid-Peninsula and MPB
conform in all material respects with all applicable ordinances, regulations and
zoning laws. All tangible properties of Mid-Peninsula and MPB are in a good
state of maintenance and repair and are adequate for the current business of 
Mid-Peninsula and MPB. No properties of Mid-Peninsula and MPB, and, to the best
of Mid-Peninsula's knowledge, no properties in which Mid-Peninsula or MPB holds
a collateral or contingent interest or purchase option, are the subject of any
pending or threatened investigation, claim or proceeding relating to the use,
storage or disposal on such property of or contamination of such property by any
toxic or hazardous waste material or substance. To the best of Mid-Peninsula's
knowledge, neither Mid-Peninsula nor MPB owns, possesses or has a collateral or
contingent interest or purchase option in any properties or other assets which
contain or have located within or thereon any hazardous or toxic waste material
or substance unless the location of such hazardous or toxic waste material or
other substance or its use thereon conforms in all material respects with all
federal, state and local laws, rules, regulations or other provisions regulating
the discharge of materials into the environment. As to any real property not
owned or leased by Mid-Peninsula or MPB and held as security for a loan or in
which Mid-Peninsula or MPB otherwise has an interest, neither Mid-Peninsula or
MPB has controlled, directed or participated in the operation or management of
any such real property or any facilities or enterprise conducted thereon, such
that it has become an owner or operator of such real property under applicable
environmental laws.

                 (ii) All properties held by Mid-Peninsula or MPB under leases
are held under valid, binding and enforceable leases, with such exceptions as
are not material and do not interfere with the conduct of the business of Mid-
Peninsula or MPB, and Mid-Peninsula and MPB enjoy quiet and peaceful possession
of such leased property. Neither Mid-Peninsula nor MPB is in material default in
any respect under any material lease, agreement or obligation regarding its
properties to which it is a party or by which it is bound.

                 (iii) Except as disclosed to Cupertino in writing, all of Mid-
Peninsula's and MPB's rights and obligations under the leases referred to in
Section 5(j)(ii) above do not require the consent of any other party to the
transaction contemplated by this Agreement and the Merger Agreement. Where
required, Mid-Peninsula and MPB shall obtain, prior to the Effective Date, the
consent of such parties to such transactions.

           k.    Material Contracts. Except as previously disclosed to Cupertino
                 ------------------
in writing and excluding loans, lines of credit, loan commitments or letters of
credit to which 

                                      31
<PAGE>
 
Mid-Peninsula or MPB is a party, neither Mid-Peninsula nor MPB is a party to or
bound by any contract or other agreement made in the Ordinary Course of Business
which involves aggregate future payments by or to Mid-Peninsula or MPB of more
than $20,000 and which is made for a fixed period expiring more than one year
from the date hereof, and neither Mid-Peninsula nor MPB is a party to or bound
by any agreement not made in the Ordinary Course of Business which is to be
performed at or after the date hereof. Each of the contracts and agreements
disclosed to Cupertino pursuant to this Section 5(k) is a legal and binding
obligation (subject to applicable bankruptcy, insolvency and similar laws
affecting creditors' rights generally and subject, as to enforceability, to
equitable principles of general applicability), and no breach or default (and no
condition which, with notice or passage of time, or both, could become a breach
or default) exists with respect thereto.

           l.    Classified Loans. Except as previously disclosed to Cupertino
                 ----------------
in writing, there are no loans presently owned by Mid-Peninsula or MPB that have
been classified by Mid-Peninsula or MPB management or Mid-Peninsula or MPB
internal policy or procedure, any outside review examiner, accountant or any
bank regulatory authority as "Other Loans Specially Mentioned," "Special
Mention," "Substandard," "Doubtful," or "Loss" or classified using categories or
words with similar import and all loans or portions thereof so classified have
been charged off to the extent required. Mid-Peninsula and MPB regularly review
and appropriately classify their loans in accordance with all applicable legal
and regulatory requirements and generally accepted banking practices. All loans
and investments of Mid-Peninsula and MPB are legal, valid and binding
obligations enforceable in accordance with their respective terms and are not
subject to any setoffs, counterclaims or disputes (subject to applicable
bankruptcy, insolvency and similar laws affecting creditors' rights generally
and subject, as to enforceability, to equitable principles of general
applicability), except as disclosed to Cupertino in writing or reserved for in
the unaudited balance sheet of Mid-Peninsula as of March 31, 1996, and were duly
authorized under and made in compliance with applicable federal and state laws
and regulations. Neither Mid-Peninsula nor MPB has any extensions of credit,
investments, guarantees, indemnification agreements or commitments for the same
(including without limitation commitments to issue letters of credit, to create
acceptances, or to repurchase securities, federal funds or other assets) other
than those documented on the books and records of Mid-Peninsula and MPB.

           m.    Restrictions on Investments. Except for pledges to secure
                 ---------------------------
public and trust deposits and repurchase agreements in the Ordinary Course of
Business, none of the investments reflected in the Mid-Peninsula balance sheet
as of March 31, 1996, and none of the investments made by Mid-Peninsula or MPB
since March 31, 1996, is subject to any restriction, whether contractual or
statutory, which materially impairs the ability of Mid-Peninsula or MPB to
freely dispose of such investment at any time.

           n.    Employment Benefit Plans/ERISA.
                 ------------------------------

and commitments applicable to former employees or retired employees, or for
which such persons are eligible) (collectively, "Employee Plans"), if any,
together with copies of all such Employee Plans that are documented and any and
all contracts of employment, and has made available to Cupertino any Board of
Directors' minutes (or committee minutes) authorizing, approving or guaranteeing
such Employee Plans and contracts; and

                 (ii) All contributions, premiums or other payments due from 
Mid-Peninsula and MPB to (or under) any Employee Plans have been fully paid or
adequately provided for on Mid-Peninsula's audited financial statements for the
year ended December 31, 1995 or unaudited financial statements for the three
months ended March 31, 1996. All accruals thereon (including, where appropriate,
proportional accruals for partial periods) have been made in accordance with
generally accepted accounting principles consistently applied on a reasonable
basis; and

                 (iii) Mid-Peninsula has disclosed in writing to Cupertino the
names of each director, officer and employee of Mid-Peninsula and MPB; and

                 (iv) The Employee Plans have been administered where required
in substantial compliance with ERISA, the IRC and the terms of such Employee
Plans, and there is no pending or threatened litigation relating to any such
Employee Plan; and

                 (v) Mid-Peninsula and MPB have not offered in the past health
benefits for retired employees; and

                 (vi) Each Employee Plan is in full force and effect, and
neither Mid-Peninsula, MPB nor any other party is in material default under any
of them, and there have been no claims of default and there are no facts or
conditions which if continued, or on notice, will result in a material default
under any Employee Plans; and

                 (vii) Mid-Peninsula has provided to Cupertino a list of all
agreements or other understandings pursuant to which the consummation of the
transactions contemplated hereby will (a) entitle any current or former employee
or officer of Mid-Peninsula or MPB to severance pay, unemployment compensation
or any other payment, or (b) accelerate the time of payment or vesting or
increase the amount of compensation due any such employee or officer.

           o.    Collective Bargaining and Employment Agreements. Except as
                 -----------------------------------------------
provided in this Agreement or as previously disclosed to Cupertino in writing,
neither Mid-Peninsula nor MPB has any union or collective bargaining or written
employment agreements, contracts or other agreements with any labor organization
or with any member 

                                      33
<PAGE>
 
of management, or any management or consultation agreement not terminable at
will by Mid-Peninsula or MPB without liability and no such contract or agreement
has been requested by, or is under discussion by management with, any group of
employees, any member of management or any other person. There are no material
controversies pending between Mid-Peninsula or MPB and any current or former
employees, and to the best of Mid-Peninsula's knowledge, there are no efforts
presently being made by any labor union seeking to organize any of such
employees.

           p.    Compensation of Officers and Employees.  Except as previously
                 --------------------------------------                       
disclosed to Cupertino in writing, (i) no officer or employee of Mid-Peninsula
or MPB is receiving aggregate direct remuneration at a rate exceeding $60,000
per annum, and (ii) the consummation of the transactions contemplated by this
Agreement and the Merger Agreement will not (either alone or upon the occurrence
of any additional or further acts or events) result in any payment (whether of
severance pay or otherwise) becoming due from Mid-Peninsula, MPB or Cupertino to
any employee of Mid-Peninsula or MPB.

           q.    Legal Actions and Proceedings. Except as previously disclosed
                 -----------------------------
to Cupertino in writing, neither Mid-Peninsula nor MPB is a party to, or so far
as known to either of them, threatened with, and to Mid-Peninsula's knowledge,
there is no reasonable basis for, any legal action or other proceeding or
investigation before any court, any arbitrator of any kind or any government
agency, and neither Mid-Peninsula nor MPB is subject to any potential adverse
claim, the outcome of which could involve the payment or receipt by Mid-
Peninsula or MPB of any amount in excess of $50,000, unless an insurer has
agreed to defend against and pay the amount of any resulting liability without
reservation, or, if any such legal action, proceeding, investigation or claim
will not involve the payment by Mid-Peninsula or MPB of a monetary amount, which
could materially adversely affect Mid-Peninsula or MPB or their business or
property or the transactions contemplated hereby. Mid-Peninsula has no knowledge
of any pending or threatened claims or charges under the Community Reinvestment
Act, before the Equal Employment Opportunity Commission, the California
Department of Fair Housing & Economic Development, the California Unemployment
Appeals Board, or any federal or state human relations commission or agency.
There is no labor dispute, strike, slow-down or stoppage pending or, to the best
of the knowledge of Mid-Peninsula, threatened against Mid-Peninsula or MPB.

           r.    Execution and Delivery of the Agreement.
                 --------------------------------------- 

                 (i) The execution and delivery of this Agreement and the Merger
Agreement have been duly authorized by the Board of Directors of Mid-Peninsula
and, when the principal terms of the Merger, this Agreement and the Merger
Agreement have been duly approved by the affirmative vote of the holders of a
majority of the outstanding Bancorp Shares at a meeting of shareholders duly
called and held, the Merger, this Agreement and the Merger Agreement will be
duly and validly authorized by all necessary corporate action on the part of 
Mid-Peninsula.

                                      34
<PAGE>
 
                 (ii) This Agreement has been duly executed and delivered by 
Mid-Peninsula and (assuming due execution and delivery by Cupertino) 
constitutes, and the Merger Agreement, upon its execution and delivery by Mid-
Peninsula (and assuming due execution and delivery by Cupertino) will 
constitute, a legal and binding obligation of Mid-Peninsula in accordance with 
its terms.

                 (iii) The execution and delivery by Mid-Peninsula of this
Agreement and the Merger Agreement and the consummation of the transactions
herein and therein contemplated (a) do not violate any provision of the Articles
of Incorporation or Bylaws of Mid-Peninsula or MPB, respectively, or violate in
any material respect any provision of federal or state law or any government
rule or regulation (assuming (1) receipt of the Government Approvals, (2)
receipt of the requisite Mid-Peninsula shareholder approval referred to in
Section 5(r)(i) hereof, (3) due registration of the Bancorp Shares under the
1933 Act, and (4) receipt of appropriate permits or approvals under state
securities or "blue sky" laws, and (b) do not require any consent of any person
under, conflict in any material respect with or result in a material breach of,
or accelerate the performance required by any of the terms of, any material debt
instrument, lease, license, covenant, agreement or understanding to which Mid-
Peninsula or MPB is a party or by which it is bound or any order, ruling,
decree, judgment, arbitration award or stipulation to which Mid-Peninsula or MPB
is subject, or constitute a material default thereunder or result in the
creation of any lien, claim, security interest, encumbrance, charge, restriction
or right of any third party of any kind whatsoever upon any of the properties or
assets of Mid-Peninsula or MPB.

           s.    Retention of Broker or Consultant.  No broker, agent, finder,
                 ---------------------------------                            
consultant or other party (other than legal, compliance, loan auditors and
accounting advisors) has been retained by Mid-Peninsula or MPB or is entitled to
be paid based upon any agreements, arrangements or understandings made by Mid-
Peninsula or MPB in connection with any of the transactions contemplated by this
Agreement or the Merger Agreement, except that Mid-Peninsula has engaged the
firm of Alex. Brown & Sons Incorporated to act as its financial advisor and to
render an opinion regarding the fairness of the Conversion Ratio in the Merger,
from a financial point of view, to Mid-Peninsula shareholders.  Mid-Peninsula
has provided Cupertino with a true and accurate copy of its agreement(s) with
Alex. Brown & Sons Incorporated.

           t.    Insurance. Mid-Peninsula and MPB are and continuously since
                 ---------
their inception have been, insured with reputable insurers against all risks
normally insured against by bank holding companies and banks, and all of the
insurance policies and bonds maintained by Mid-Peninsula and MPB are in full
force and effect, Mid-Peninsula and MPB are not in default thereunder and all
material claims thereunder have been filed in due and timely fashion. In the
best judgment of the management of Mid-Peninsula and MPB, such insurance
coverage is adequate for Mid-Peninsula and MPB. Since December 31, 1995, there
has not been any damage to, destruction of, or loss of any assets of Mid-
Peninsula or MPB not covered by insurance that could materially and adversely
affect the business, financial condition, properties, assets or results of
operations of Mid-Peninsula or MPB.

                 ------------------                                           
Peninsula balance sheets dated December 31, 1995, March 31, 1996, and as of the
Determination Date are and will be adequate in all material respects under the
requirements of all applicable state and federal laws and regulations to provide
for possible loan losses on outstanding loans, net of recoveries.  Mid-Peninsula
has disclosed to Cupertino in writing prior to the date hereof, and will
promptly inform Cupertino of the amounts of all loans, leases, other extensions
of credit or commitments, or other interest-bearing assets of Mid-Peninsula and
MPB, that have been classified as of the date hereof or hereafter by Mid-
Peninsula or MPB management or Mid-Peninsula or MPB internal policy or
procedure, any outside review examiner, accountant or any bank regulatory
authority as "Other Loans Specially Mentioned," "Special Mention,"
"Substandard," "Doubtful," or "Loss" or classified using categories or words
with similar import in the case of loans (or that would have been so classified,
in the case of other interest-bearing assets, had they been loans).
Notwithstanding the above, Mid-Peninsula shall be under no obligation to
disclose to Cupertino any such classification by any bank regulatory authority,
where such disclosure would violate any obligation of confidentiality of Mid-
Peninsula or MPB imposed by such bank regulatory authority.  Mid-Peninsula has
furnished and will continue to furnish to Cupertino true and accurate
information concerning the loan portfolio of Mid-Peninsula and MPB, and no
material information with respect to the loan portfolio has been or will be
withheld from Cupertino.

           v.    Transactions With Affiliates.  Except in the Ordinary Course of
                 ----------------------------                                   
Business, neither Mid-Peninsula nor MPB has extended credit, committed itself to
extend credit, or transferred any asset to or assumed or guaranteed any
liability of the employees or directors of Mid-Peninsula or MPB, or to any
spouse or child of any of them, or to any of their "affiliates" or "associates"
as such terms are defined in Rule 405 under the 1933 Act.  Neither Mid-Peninsula
nor MPB has entered into any other transactions with the employees or directors
of Mid-Peninsula or MPB or any spouse or child of any of them, or any of their
affiliates or associates, except as disclosed in writing to Cupertino.  Any such
transactions have been on terms no less favorable to Mid-Peninsula and MPB than
those which would prevail in an arms-length transaction with an independent
third party.  Neither Mid-Peninsula nor MPB has violated any applicable
regulation of any government agency or regulatory authority having jurisdiction
over Mid-Peninsula or MPB in connection with any such transactions described in
this subsection v.

           w.    Information in Mid-Peninsula Registration Statement. The

the Mid-Peninsula Registration Statement and the Joint Proxy
Statement/Prospectus, or in the Applications to be filed to obtain the
Government Approvals, does not and will not contain any untrue statement of any
material fact or omit or will 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 are made, not misleading; provided, however, that

an earlier date. All financial statements of Mid-Peninsula included in the Mid-

                                      36

Joint Proxy Statement/Prospectus, or the Applications, will present fairly the
financial condition and results of operations of Mid-Peninsula at the dates and
for the periods covered by such statements in accordance with generally accepted
accounting principles consistently applied throughout the periods covered by
such statements. Mid-Peninsula shall promptly advise Cupertino in writing if
prior to the Effective Time of the Merger Mid-Peninsula shall obtain knowledge
of any facts that would make it necessary to amend or supplement the Mid-
Peninsula Registration Statement, the Joint Proxy Statement/Prospectus or any
Application, in order to make the statements therein not misleading or to comply
with applicable law or regulation.

           x.    Accuracy and Effective Date of Representations and Warranties,
                 --------------------------------------------------------------
Covenants and Agreements.  Each representation, warranty, covenant and agreement
- ------------------------                                                        
of Mid-Peninsula set forth in this Agreement shall be deemed to be made on and
as of the date hereof (except to the extent that a representation or warranty is
qualified as set forth in a Schedule corresponding in number with the applicable
section of such representation or warranty and delivered on or before the
Document Delivery Date, and upon such delivery it shall be deemed made on and as
of the date of delivery), the Closing Date and the Effective Time of the Merger.

Peninsula in any certificate, agreement, schedule or other document furnished or
to be furnished in connection with the transactions contemplated by this

incorrect in any material respect as of the date furnished or contains or will
contain any untrue statement of a material fact or omits or will omit to state
any material fact necessary to make such representation, warranty or statement
not misleading to Cupertino.

of Mid-Peninsula and Cupertino for approval. Cupertino shall cooperate in all
reasonable respects with regard to the preparation of the Joint Proxy
Statement/Prospectus. The Joint Proxy Statement/Prospectus in definitive form is
expected to serve as the prospectus to be included in the Mid-Peninsula
Registration Statement. Mid-

and auditors to cooperate with the other's counsel and auditors in the

           b.    Effectiveness of Registration Statement. Mid-Peninsula and
                 ---------------------------------------
Cupertino shall use their best efforts to have the Mid-Peninsula Registration
Statement and any amendments or supplements thereto declared effective under the
1933 Act as soon as practicable, and thereafter Mid-Peninsula and Cupertino
shall distribute the Joint Proxy Statement/Prospectus to holders of their
respective common stock in accordance with applicable laws and the Articles of
Incorporation and Bylaws of each.

           c.    Sales and Resales of Common Stock.  Mid-Peninsula shall not be
                 ---------------------------------                             
required to maintain the effectiveness of the Mid-Peninsula Registration
Statement for the purpose of sale or resale of the Bancorp Shares by any person.

           d.    Rule 145. Securities representing Bancorp Shares issued to
                 --------
affiliates of Cupertino (as determined by counsel to Mid-Peninsula and
Cupertino) under Rule 145 of the 1933 Act pursuant to the Merger Agreement may
be subject to stop transfer orders which confirm that such securities
representing Bancorp Shares have been issued or transferred to the registered
holder as the result of a transaction to which Rule 145 under the 1933 Act
applies, and that such securities may not be sold, hypothecated, transferred or
assigned, and the issuer or its transfer agent shall not be required to give
effect to any attempted sale, hypothecation, transfer or assignment, except (i)
pursuant to a then current effective registration statement under the 1933 Act,

neither Cupertino nor CNB shall be a party to or threatened with, and to the
best of Cupertino's knowledge there is no reasonable basis for, any legal action
or other proceeding before any court, any arbitrator of any kind or any
government agency, which legal action or proceeding, in the reasonable judgment
of Mid-Peninsula, could materially adversely affect Cupertino and CNB, taken as
a whole, or their business, financial condition, results of operations or
assets.

                 ---------------------

with the manner in which Mid-Peninsula or Cupertino has conducted its business
previously;

                 (ii) have a material adverse effect upon the business,

subject to customary assumptions and exceptions included in such opinions and
the prior delivery of certificates from Cupertino and Mid-Peninsula in form and

the effect that under federal income tax law and California income and franchise
tax law:

                           MID-PENINSULA BANCORP AND
                      CUPERTINO NATIONAL BANCORP TO MERGE



PALO ALTO, Calif. -- Mid-Peninsula Bancorp (Nasdaq Bulletin Board: MPBK), Palo
Alto, CA and Cupertino National Bancorp (Nasdaq: CUNB), Cupertino, CA announced
today the signing of a definitive agreement for a "merger of equals" between the
two companies.  The merger will result in the formation of the largest multi-
bank holding company based in the San Francisco Peninsula/South Bay region, and
the third-largest publicly traded independent bank holding company in the San
Francisco Bay area, with total assets of approximately $500 million and equity
of over $40 million.  The resulting entity will be named Greater Bay Bancorp.
Mid-Peninsula Bank and Cupertino National Bank & Trust will operate as wholly
owned subsidiaries of Greater Bay Bancorp and will focus on serving the greater
Bay area, including the Peninsula and South Bay markets, through their seven
office locations.

The terms of the agreement provide for Cupertino National Bancorp shareholders
to receive .81522 of a share of Mid-Peninsula Bancorp stock for each share of
Cupertino National Bancorp in a tax-free exchange to be accounted for as a
"pooling-of-interests." As part of the agreement, Mid-Peninsula will list its
shares on the Nasdaq National Market System, and, concurrent with closing, will
be renamed Greater Bay Bancorp. Following the merger, the shareholders of Mid-
Peninsula Bancorp will own approximately 51% of the combined company and the
shareholders of Cupertino National Bancorp will own approximately 49% of the
combined company, giving effect to all outstanding options.

The transaction is anticipated to be accretive in 1997 to shareholders of both
companies, based on reductions in duplicative administrative functions and
revenue enhancements resulting from an expanded product line and increased
lending capacity. Management of the organizations believe that significant
opportunities exist to enhance the spectrum of financial services offered to
both existing and potential clients.

<PAGE>
 
Greater Bay Bancorp's new Board of Directors will consist of five directors from
each company, with Duncan L. Matteson (Chairman of Mid-Peninsula Bancorp) and
John M. Gatto (Chairman of Cupertino National Bancorp) serving as co-Chairmen.
David L. Kalkbrenner, who will serve as President and Chief Executive Officer of
the holding company, will continue as President and Chief Executive Officer of
Mid-Peninsula Bank, and C. Donald Allen will remain as Chairman and Chief
Executive Officer of Cupertino National Bank & Trust. Steven C. Smith, the Chief
Operating Officer of Cupertino National Bancorp, will serve as Chief Operating
Officer and Chief Financial Officer of the holding company.

The adoption of the multi-bank holding company format will facilitate the
addition of other independent banks to the organization and permits the
preservation of the personalized relationship banking philosophy espoused by
community banking organizations. "The combination of these two successful
institutions presents significant benefits for our clients, employees and
shareholders," commented David Kalkbrenner. "This is a rare opportunity to
create one of the largest locally based community bank franchises servicing the
needs of the business and venture community in the greater Bay area. The
complementary nature of our business philosophies, services provided and markets
will position our company for continued growth and profitability. The unique fit
offered by the services Cupertino National Bank has developed, particularly
trust services, will provide the opportunity and resources necessary to expand
and enhance the profitability of our core banking business as well as increase
opportunities to provide financial services not previously available to our
clients. Mid-Peninsula's historical cost-efficiency, combined with the wide
breadth of services offered by Cupertino National, will enable the combined
organization to provide, on a more cost-effective basis, a wider range of
services to an expanded client base."

Cupertino National Bancorp President and Chief Executive Officer Don Allen
commented, "The thrust of Cupertino National Bank & Trust has focused on
providing specific niche services that fit with its vision of becoming a
significant force throughout the Bay Area. The combination of our two banks will
preserve this focus and assure that significantly greater resources are
available for this effort. As a competitor, we have admired Mid-Peninsula Bank's
stellar performance for some time; we look forward to a combined focus on
providing the best client services available anywhere. The ability to leverage
the investment Cupertino National has made in its Trust and Venture Lending
units through the strong client relationships enjoyed by Mid-Peninsula is
expected to yield immediate incremental income. Additionally, the combined
strength of our organization will enable Cupertino National's Venture Lending
unit to compete more aggressively in the technology, life sciences and emerging
growth industries, as a result of increased lending limits and additional
resources."

In connection with the merger agreement, Mid-Peninsula and Cupertino will grant
each other options to purchase up to 19.0% of the outstanding shares of each
other's common stock under certain circumstances in the event the transaction is
terminated. The merger is expected to be completed in the fourth quarter of
1996, subject to shareholder and regulatory approvals.

Mid-Peninsula Bancorp had $233.0 million in assets, $209.2 million in deposits
and $22.0 million in shareholders' equity as of March 31, 1996. Cupertino
National Bancorp had $255.0 million in assets, $231.8 million in deposits and
$19.4 million in shareholders' equity as of that date.
