                                TERMS OF MERGER
                                ---------------

     2.1. Effect of Merger and Surviving Corporation.  At the Effective Time
          ------------------------------------------
of the Merger, Newco will be merged with and into BOP pursuant to the terms,
conditions and provisions of the Agreement of Merger and in accordance with the
applicable provisions of the CGCL.  By virtue of the Merger, all the rights,
privileges, powers and franchises and all property and assets of every kind and
description of Newco and BOP shall be vested in and be held and enjoyed by the
Surviving Corporation, without further act or deed, and all the interests of
every kind of Newco and BOP, including all debts due to either of them on
whatever account, shall be the property of the Surviving Corporation as they
were of Newco and BOP and the title to any interest in real property and any
interest in personal property vested by deed or otherwise in either Newco or BOP
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 Newco and BOP shall be
preserved unimpaired and all debts, liabilities and duties of Newco and BOP
shall be debts, liabilities and duties of the Surviving Corporation and may be
enforced against it to the same extent as if said debts, liabilities and duties
had been incurred or contracted by it.

     2.2. Stock of BOP.  Subject to Section 2.4, each share of BOP Stock
          ------------
issued and outstanding immediately prior to the Effective Time of the Merger
shall, without any further action on the part of BOP or the holders of such
shares, be treated on the basis set forth herein.

          (a)  Conversion of BOP Stock.  At the Effective Time of the Merger,
               -----------------------
pursuant to the Agreement of Merger, each outstanding share of BOP Stock
excluding any BOP Perfected Dissenting Shares shall, without any further action
on the part of BOP or the holders of any such shares, be automatically canceled
and cease to be an issued and outstanding share of BOP Stock and be converted
into shares of GBB Stock (the "Conversion Ratio") as follows:

          (i) If the Average Closing Price is greater than or equal to $37.91 or
less than or equal to $46.34, 0.6850 shares of GBB Stock;

          (ii) If the Average Closing Price is greater than $46.34, a number of
shares of GBB Stock equal to the quotient obtained by dividing (x) $31.74 plus
the product of .3333 times the difference between the Average Closing Price and
$46.34, by (y) the Average Closing Price; or

          (iii)  If the Average Closing Price is less than $37.91, GBB may, but
shall not be required to, elect the Top Up Option.  GBB shall notify BOP in
writing, within one Business Day from the date of calculation of the Average
Closing Price, whether GBB will elect the Top Up Option.  If GBB does not elect
the Top Up Option, BOP may terminate the Agreement pursuant to Section 13.1(l)
within one Business Day from the date of receipt of written notice from GBB of
its decision not to elect the Top Up Option.  If BOP does not give GBB written
notice of its decision to so terminate the Agreement within such one Business
Day period, the Conversion Ratio will be 0.6850 shares of GBB Stock.  If GBB
elects the Top Up Option, the

                                      13
<PAGE>

Conversion Ratio will equal that number of shares of GBB Stock equal to the
quotient obtained by dividing $25.97 by the Average Closing Price.

          (iv) In the event that, prior to the Closing Date, GBB publicly
announces the signing of a definitive agreement with a third party with respect
to a business combination, tender offer or similar transaction which if
consummated would result in the GBB shareholders as of the date of such
announcement owning less than 51% of the outstanding shares of common stock of
the surviving corporation, the price to be paid to GBB shareholders in such
transaction would exceed $46.34 and such transaction is not terminated or
abandoned prior to the Closing Date (a "GBB Acquisition Transaction"), the
Conversion Ratio shall be 0.6850 shares of GBB Stock.  If such GBB Acquisition
Transaction is terminated or abandoned during the period for determining the
Average Closing Price, GBB can elect to either set the Conversion Ratio at
0.6850 shares of GBB Stock or unilaterally delay the Closing Date to a date
which is 25 trading days after the date of the public announcement of the
termination or abandonment of such GBB Acquisition Transaction.  To preserve the
rights of holders of shares of BOP Stock pursuant to this Section 2.2(a)(iv),
GBB and BOP agree to coordinate the closing of any GBB Acquisition Transaction
with the Closing and to cooperate with such third party in otherwise
accomplishing the purpose hereof.

          (b) BOP Perfected Dissenting Shares.  BOP Perfected Dissenting Shares
              -------------------------------
shall not be converted into shares of GBB Stock, but shall, after the Effective
Time of the Merger, be entitled only to such rights as are granted them by
Chapter 13 of the CGCL.  Each dissenting shareholder who is entitled to payment
for his shares of BOP Stock shall receive such payment in an amount as
determined pursuant to Chapter 13 of the CGCL.

          (c) Dividends, Etc.  If,  prior to the Effective Time of the Merger,
              --------------
GBB shall declare a stock dividend or distribution upon or subdivide, split up,

multiplying (a) the closing price of GBB Stock reported on the Nasdaq National
Market System on the Business Day immediately preceding the Closing Date times

     2.5  Exchange Procedures.
          -------------------

          (a) As of the Effective Time of the Merger, GBB shall have deposited
with the Exchange Agent for the benefit of the holders of shares of BOP Stock,
for exchange in accordance with this Section 2.5 through the Exchange Agent,
certificates representing the shares of GBB Stock issuable pursuant to Section
2.2 in exchange for shares of BOP Stock outstanding immediately prior to the
Effective Time of the Merger, and funds in an amount not less than the amount of
cash payable in lieu of fractional shares of GBB Stock which would otherwise be
issuable in connection with Section 2.2 hereof but for the operation of Section
2.4 of this Agreement (collectively, the "Exchange Fund").

          (b) GBB shall direct the Exchange Agent to mail, promptly after the
Effective Time of the Merger, to each holder of record of a certificate or
certificates which immediately prior to the Effective Time of the Merger
represented outstanding shares of BOP Stock (the "Certificates") whose shares
were converted into the right to receive shares of GBB Stock pursuant to Section
2.2 hereof, (i) a letter of transmittal (which shall specify that delivery shall
be effected, and risk of loss and title to the Certificates shall pass, only
upon delivery of the Certificates to the Exchange Agent and shall be in such
form and have such other provisions as GBB and BOP may reasonably specify), and
(ii) instructions for use in effecting the surrender of the Certificates in
exchange for certificates representing shares of GBB Stock.  Upon surrender of a
Certificate for cancellation to the Exchange Agent or to such other agent or
agents as may be appointed by GBB, together with such letter of transmittal,
duly executed, the holder of such  Certificate shall be entitled to receive in
exchange therefor a certificate representing that number of whole shares of GBB
Stock and cash in lieu of fractional shares which such holder has the right to
receive pursuant to Sections 2.2 and 2.4 hereof, and the Certificate so
surrendered shall forthwith be canceled.  In the event a certificate is
surrendered representing BOP Stock, the transfer of ownership of which is not
registered in the transfer records of BOP, a certificate representing the proper
number of shares of GBB Stock may be issued to a transferee if the Certificate
representing such BOP Stock is presented to the Exchange Agent, accompanied by
all documents required to evidence and effect such transfer and by evidence that
any applicable stock transfer taxes have been paid.  Until surrendered as
contemplated by this Section 2.5, each Certificate shall be deemed at any time
after the Effective Time of the Merger to represent only the right to receive
upon such surrender the certificate representing shares of GBB Stock and cash in
lieu of any fractional shares of stock as contemplated by this Section 2.5.
Notwithstanding anything to the contrary set forth herein, if any holder of
shares of BOP should be unable to surrender the Certificates for such shares,
because they have been lost or destroyed, such holder may deliver in lieu
thereof a bond in form and substance and with surety reasonably satisfactory to
GBB and shall be entitled to receive the certificate representing the proper
number of shares of GBB Stock and cash in lieu of fractional shares in
accordance with Sections 2.2 and 2.4 hereof.

          (c) No dividends or other distributions declared or made with respect
to GBB Stock with a record date after the Effective Time of the Merger shall be
paid to the holder of any unsurrendered Certificate with respect to the shares
of GBB Stock represented thereby and no cash payment in lieu of fractional
shares shall be paid to any such holder pursuant to Section 2.4 until the holder
of record of such Certificate shall surrender such Certificate.  Subject to the

                                      15
<PAGE>

effect of applicable laws, following surrender of any such Certificate, there
shall be paid to the record holder of the certificates representing whole shares
of GBB Stock issued in exchange thereof, without interest, (i) at the time of
such surrender, the amount of any cash payable in lieu of a fractional share of
GBB Stock to which such holder is entitled pursuant to Section 2.4 and the
amount of dividends or other distributions with a record date after the
Effective Time of the Merger theretofore paid with respect to such whole shares
of GBB Stock, and (ii) at the appropriate payment date, the amount of dividends
or other distributions with a record date after the Effective Time of the Merger
but prior to surrender and a payment date subsequent to surrender payable with
respect to such whole shares of GBB Stock.

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

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

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

          (g) The Exchange Agent shall not be entitled to vote or exercise any
rights of ownership with respect to the shares of GBB 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 GBB Stock for
the account of the Persons entitled thereto.

          (h)  Certificates surrendered for exchange by any Person constituting
an "Affiliate" of BOP for purposes of Rule 145(c) under the Securities Act shall
not be exchanged for certificates representing whole shares of GBB Stock until
GBB has received a written agreement from such person as provided in Section
6.9.

     2.6. Directors of Surviving Corporation.  Immediately after the Effective
          ----------------------------------

Time of the Merger, the BOP Board of Directors shall continue to meet on a
monthly basis and receive its current director fees of $600.00 per monthly
meeting attended and $125.00 per committee meeting attended. Commencing with the
first calendar quarter after such six month period, the BOP Board of Directors
will meet on a quarterly basis and the BOP director fees will be revised to
equal the amount of director fees paid to members of the Boards of Directors of
the Banks.

Effective Time of the Merger, the executive officers of the Surviving

                                  ARTICLE 4.

                     REPRESENTATIONS AND WARRANTIES OF BOP
                     -------------------------------------

                BOP represents and warrants to GBB as follows:

     4.1. Incorporation, Standing and Power.  BOP is a California state
          ---------------------------------
chartered bank duly organized, validly existing and in good standing under the
laws of the State of California and is authorized by the DFI to conduct a
general banking business. BOP's deposits are insured by the FDIC in the manner
and to the fullest extent provided by law.  BOP has all requisite corporate
power and authority to own, lease and operate its properties and assets and to
carry on its business as presently conducted.  Neither the scope of the business
of BOP nor the location of any of its properties requires that BOP be licensed
to do business in any jurisdiction other than the State of California where the
failure to be so licensed would, individually or in the aggregate, have a
material adverse effect on the business, financial condition, results of
operations or prospects of BOP.  BOP has delivered to GBB true and correct
copies of its Articles of Incorporation and Bylaws, as amended, and in effect as
of the date hereof.

     4.2. Capitalization.    As of the date of this Agreement, the authorized
          --------------
capital stock of BOP consists of 20,000,000 shares of BOP Stock, of which
1,444,797 shares are outstanding as of March 10, 2000, and 5,000,000 shares of
preferred stock, none of which is outstanding. All of the outstanding shares of
BOP Stock are duly authorized, validly issued, fully paid and nonassessable.
Except for BOP Options covering 209,282 shares of BOP Stock granted pursuant to
the BOP Stock Option Plan, there are no outstanding options, warrants or other
rights in or with respect to the unissued shares of BOP Stock nor any securities
convertible into such stock, and BOP is not obligated to issue any additional
shares of its common stock or any additional options, warrants or other rights
in or with respect to the unissued shares of such stock or any other securities
convertible into such stock.  BOP has furnished GBB a list (the "BOP Option
List") setting forth the name of each holder of a BOP Option, the number of
shares of BOP Stock covered by each such option, the vesting schedule of such
option, the exercise price per share and the expiration date of each such
option.

     4.3. Subsidiaries.   BOP does not own, directly or indirectly (except as
          ------------
a pledgee pursuant to loans or upon acquisition in satisfaction of debt
previously contracted), the outstanding stock or equity or other voting interest
in any Person.

     4.4. Financial Statements.  BOP has previously furnished to GBB a copy of
          --------------------
the Financial Statements of BOP.  The Financial Statements of BOP:  (a) present
fairly the  financial condition of BOP as of the respective dates indicated and
its  results of operations and changes in cash flows, for the respective periods
then ended, subject, in the case of the unaudited interim financial statements,
to normal recurring adjustments; (b) have been prepared in accordance with
generally accepted accounting principles consistently applied (except as
otherwise indicated therein); (c) set forth as of the respective dates indicated
adequate reserves for loan losses and other contingencies; and (d) are based
upon the books and records of BOP.


                                      18
<PAGE>

     4.5. Reports and Filings. Except as set forth in a list (the "BOP Filings
          -------------------
List"), since January 1, 1997, BOP has filed all reports, returns, registrations
and statements (collectively, "BOP Filings"), together with any amendments
required to be made with respect thereto, that were required to be filed with
(a) the FDIC, (b) the DFI, (c) the SEC and (d) any other applicable Governmental
Entity, including taxing authorities, except where the failure to file such
reports, returns, registrations or statements has not had and is not reasonably
expected to have a material adverse effect on the business, financial condition,
results of operations or prospects of BOP. No administrative actions have been
taken or orders issued in connection with such BOP Filings. As of their
respective dates, each of such BOP Filings (y) complied in all material respects
with all laws and regulations enforced or promulgated by the Governmental Entity
with which it was filed (or was amended so as to be in compliance promptly
following discovery of any such noncompliance); and (z) did not 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. Any financial
statement contained in any of such BOP Filings fairly presented the financial
position of BOP, and was prepared in accordance with generally accepted
accounting principles or banking regulations consistently applied, except as
stated therein, during the periods involved. BOP has furnished or made available
to GBB true and correct copies of all BOP Filings filed by BOP since January 1,
1997.

     4.6. Authority of BOP. The execution and delivery by BOP of this Agreement
          ----------------
and the Agreement of Merger and, subject to the requisite approval of the
shareholders of BOP of this Agreement and the transactions contemplated hereby,
the consummation of the transactions contemplated hereby and thereby have been
duly and validly authorized by all necessary corporate action on the part of
BOP. This Agreement is, and the Agreement of Merger will be, upon due execution
and delivery by the respective parties thereto, a valid and binding obligation
of BOP enforceable in accordance with their respective terms, except as the
enforceability thereof may be limited by bankruptcy, liquidation, receivership,
conservatorship, insolvency, moratorium or other similar laws affecting the
rights of creditors generally and by general equitable principles. Except as set
forth in a list furnished by BOP to GBB (the "BOP Conflicts and Consents List"),
neither the execution and delivery by BOP of this Agreement and the Agreement of
Merger, the consummation of the transactions contemplated herein or therein, nor
compliance by BOP with any of the provisions hereof or thereof, will: (a)
conflict with or result in a breach of any provision of its Articles of
Incorporation, as amended, or Bylaws, as amended; (b) constitute a breach of or
result in a default (or give rise to any rights of termination, cancellation or
acceleration, or any right to acquire any securities or assets) under any of the
terms, conditions or provisions of any note, bond, mortgage, indenture,
franchise, license, permit, agreement or other instrument or obligation to which
BOP is a party, or by which BOP any of its properties or assets are bound; (c)
result in the creation or imposition of any Encumbrance on any of the properties
or assets of BOP; or (d) violate any order, writ, injunction, decree, statute,
rule or regulation applicable to BOP or any of its properties or assets. Except
as set forth in the BOP Conflicts and Consents List, no consent of, approval of,
notice to or filing with any Governmental Entity having jurisdiction over any
aspect of the business or assets of BOP, and no consent of, approval of or
notice to any other Person, is required in connection with the execution and
delivery by BOP of this Agreement and the Agreement of Merger or the
consummation by BOP of the Merger or the transactions contemplated hereby or
thereby, except (i) the approval of

hereby and thereby by the shareholders of BOP; (ii) such approvals as may be
required by the FRB, the FDIC and the DFI; (iii) the filing of the Proxy

the FDIC; and (iv) the filing of the Agreement of Merger with the Secretary of
State.

          ---------
assets and business against such casualties and contingencies and in such
amounts, types and forms as are customarily appropriate for its business,
operations, properties and assets. All such insurance policies and bonds are in
full force and effect. Except as set forth in a list furnished by BOP to GBB
(the "BOP Insurance List"), no insurer under any such policy or bond has
canceled or indicated an intention to cancel or not to renew any such policy or
bond or generally disclaimed liability thereunder. Except as set forth in the
BOP Insurance List, BOP is not in default under any such policy or bond and all
material claims thereunder have been filed in a timely fashion. Set forth in the
BOP Insurance List is a list of all policies of insurance carried and owned by
BOP showing the name of the insurance company, the nature of the coverage, the
policy limit, the annual premiums and the expiration dates. There has been
delivered to GBB a copy of each such policy of insurance.

     4.8. Personal Property.  BOP has good and marketable title to all its
          -----------------
properties and assets, other than real property, owned or stated to be owned by
BOP, free and clear of all Encumbrances except:  (a) as set forth in the
Financial Statements of BOP; (b) for Encumbrances for current taxes not yet due;
(c) for Encumbrances incurred in the ordinary course of business; (d) for
Encumbrances that are not substantial in character, amount or extent and that do

property subject thereto or affected thereby, or otherwise materially impair the
conduct of business of BOP; or (e) as set forth in a list furnished by BOP to
GBB (the "BOP Personal Property List.")

     4.9. Real Estate. BOP has furnished GBB a list of real property, including
          -----------
leaseholds and all other interests in real property (other than security
interests), owned by BOP (the "BOP Real Property List"). Except as set forth on
the BOP Real Property List, BOP has duly recorded or caused to be recorded, in
the appropriate county, all recordable interests in the real property described
in the BOP Real Property List. BOP has good and marketable title to the real

Real Property List, free and clear of all Encumbrances, except (a) for rights of
lessors, co-lessees or sublessees in such matters that are reflected in the
lease; (b) for current taxes not yet due and payable; (c) for such Encumbrances,
if any, as do not materially detract from the value of or materially interfere
with the present use of such property; and (d) as described in the BOP Real

included in the BOP Real Property List, all title insurance policies and all
documents evidencing recordation of all recordable interests in real property

capacities or against or affecting any properties of BOP or any of its
subsidiaries which, if adversely determined, would have, individually or in the
aggregate, a material adverse effect upon the business, financial condition or
results of operations of BOP, or the transactions contemplated hereby, or which
may involve a judgment against BOP in excess of $50,000. Also, except as
disclosed in the BOP Litigation List, there are no material judgments, decrees,
stipulations or orders against BOP or any of its subsidiaries or enjoining their
respective directors, officers or employees in respect of, or the effect of

     4.17. Certain Material Changes. Except as specifically required, permitted
           ------------------------
or effected by this Agreement, since December 31, 1999, there has not been,
occurred or arisen any of the following (whether or not in the ordinary course
of business unless otherwise indicated):

           (a) any change in any of the assets, liabilities, permits, methods of
accounting or accounting practices, business, or manner of conducting business,
of BOP or any other event or development that has had or may reasonably be
expected to have, individually or in the aggregate, a material adverse effect on
the assets, liabilities, permits, business, financial condition, results of
operations or prospects of BOP;

           (b) any damage, destruction or other casualty loss (whether or not
covered by insurance) that has had or may reasonably be expected to have a
material adverse effect on the assets, liabilities, business, financial
condition, results of operations or prospects of BOP or that may involve a loss
of more than $50,000 in excess of applicable insurance coverage;

           (c) any amendment, modification or termination of any existing, or
entry into any new, material contract or permit that has had or may reasonably
be expected to have a material adverse effect on the assets, liabilities,
business, financial condition, results of operations or prospects of BOP;

           (d) any disposition by BOP of an asset the lack of which has had or
may reasonably be expected to have a material adverse effect on the assets,
liabilities, business, financial condition, results of operations or prospects
of BOP; or

           (e) any direct or indirect redemption, purchase or other acquisition
by BOP of any equity securities or any declaration, setting aside or payment of
any dividend or other distribution on or in respect of BOP Stock whether
consisting of money, other personal property, real property or other things of
value.

     4.18. Licenses and Permits.  BOP has all material licenses and permits
           --------------------
that are necessary for the conduct of its business, and such licenses are in
full force and effect, except for any failure to be in full force and effect
that would not, individually or in the aggregate, have a material adverse effect
on the business, financial condition, results of operations or prospects of BOP.
The properties, assets, operations and businesses of BOP are and have been
maintained and conducted, in all material respects, in compliance with all
applicable (a) licenses and permits; and (b) laws and regulations.

     4.19. Undisclosed Liabilities.  BOP does not have any liabilities or
           -----------------------
obligations, either accrued or contingent, that are material to BOP and that
have not been:  (a) reflected or disclosed in the Financial Statements of BOP;
(b) incurred subsequent to December 31, 1999 in the ordinary course of business
consistent with past practices; or (c) disclosed in a list furnished by BOP to
GBB (the "Undisclosed Liabilities List") or on any other BOP List. BOP does not
know

                                      27
<PAGE>

of any basis for the assertion against it of any liability, obligation or claim
(including, without limitation, that of any regulatory authority) that is likely
to result in or cause a material adverse change in the business, financial
condition, results of operations or prospects of BOP that is not fairly
reflected in the Financial Statements of BOP or otherwise disclosed in this
Agreement.

     4.20. Employee Benefit Plans.
           ----------------------

           (a) BOP has previously made available to GBB copies of each "employee
benefit plan," as defined in Section 3(3) of ERISA, of which BOP or any member
of the same controlled group of corporations, trades or businesses as BOP within
the meaning of Section 4001(a)(14) of ERISA ("ERISA Affiliates") is a sponsor or
participating employer or as to which BOP or any of its ERISA Affiliates makes
contributions or is required to make contributions and which  is subject to any
provision of ERISA and covers any employee, whether active or retired, of BOP or
any of its ERISA Affiliates, together with all amendments thereto, all currently
effective and related summary plan descriptions, the determination letter from
the IRS, the annual reports for the most recent three years (Form 5500
including, if applicable, Schedule B thereto) and a summary of material
modifications and all material employee communications prepared in connection
with any such plan.  Such plans are hereinafter referred to collectively as the
"Employee Plans."  BOP does not participate in an employee benefit pension plan
that is a "multiemployer plan" within the meaning of Section 3(37) of ERISA.
Each Employee Plan which is intended to be qualified in form and operation under
Section 401(a) of the Code is so qualified and the associated trust for each
such Employee Plan is exempt from tax under Section 501(a) of the Code.  No
event has occurred that will subject such Employee Plans to a material amount of
tax under Section 511 of the Code.  All amendments required to bring each
Employee Plan into conformity with all of the applicable provisions of ERISA,
the Code and all other applicable laws have been made.  Except as disclosed in a
list furnished by BOP to GBB (the "BOP Employee Plan List"), all Employee Plans
were in effect for substantially all of 1999, and there has been no material
amendment thereof (other than amendments required to comply with applicable law)
or increase in the cost thereof or benefits thereunder on or after January 1,
1999.

           (b) BOP has previously made available to GBB copies or descriptions
of each plan or arrangement maintained or otherwise contributed to by BOP or any
of its ERISA Affiliates which is not an Employee Plan and which (exclusive of
base salary and base wages) provides for any form of current or deferred
compensation, bonus, stock option, stock awards, stock-based compensation or
other forms of incentive compensation or post-termination insurance, profit
sharing, benefit, retirement, group health or insurance, disability, workers'
compensation, welfare or similar plan or arrangement for the benefit of any
employee or class of employees, whether active or retired, of BOP or any of its
ERISA Affiliates (such plans and arrangements being collectively referred to
herein as "Benefit Arrangements"). Except as disclosed in the BOP Employee Plan
List hereto, all Benefit Arrangements which are in effect were in effect for
substantially all of 1999 and to date. Except as disclosed in the BOP Employee
Plan List, there has been no material amendment thereof or increase in the cost
thereof or benefits payable thereunder since January 1, 1998. Except as set
forth in the BOP Employee Plan List, there has been no material increase in the
compensation of or benefits payable to any senior executive employee of BOP
since December 31, 1998, nor any employment, severance or

                                      28
<PAGE>

similar contract entered into with any such employee, nor any amendment to any
such contract, since December 31, 1998.

           (c) With respect to all Employee Plans and Benefit Arrangements, BOP
and its ERISA Affiliates are in compliance (other than noncompliance the cost or
liability for which is not material) 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 Code, applicable
to such plans or arrangements.  All government reports and filings required by
law have been properly and timely filed and all information required to be
distributed to participants or beneficiaries has been distributed with respect
to each Employee Plan.  BOP and its ERISA Affiliates have performed all of their
obligations under all such Employee Plans and Benefit Arrangements in all
material aspects.  There is no pending or, to the best of BOP's knowledge,
threatened legal action, proceeding or investigation against or involving any
Employee Plan or Benefit Arrangement.  No condition exists that could constitute
grounds for the termination of any Employee Plan under Section 4042 of ERISA.
No "prohibited transaction," as defined in Section 406 of ERISA and Section 4975
of the Code, has occurred with respect to any Employee Plan, or any other
employee benefit plan maintained by BOP or any of its ERISA Affiliates which is
covered by Title I of ERISA, which could subject any person (other than a person
for whom  BOP is not directly or indirectly responsible) to liability under
Title I of ERISA or to the imposition of tax under Section 4975 of the Code.  No
Employee Plan subject to Part III of Subtitle B of Title I of ERISA or Section
412 of the Code, or both, has incurred any "accumulated funding deficiency," as
defined in Section 412 of the Code, whether or not waived, nor has BOP failed to
make any contribution or pay any amount due and owing as required by the terms
of any Employee Plan or Benefit Arrangement.  No "reportable event" as defined
in ERISA has occurred with respect to any of the Employee Plans.  Neither BOP
nor any of its ERISA Affiliates has incurred nor expects to incur, directly or
indirectly, any  liability under Title IV or ERISA arising in connection with
the termination of, or a complete or partial withdrawal from, any plan covered
or previously covered by Title IV of ERISA which could constitute a liability of
GBB or of any of its Affiliates (including BOP) at or after the Effective Time
of the Merger.

           (d) Neither BOP nor any of its ERISA Affiliates has provided or is
required to provide security to any Employee Plan pursuant to Section 401(a)(29)
of the Code.  Each of the Employee Plans which is intended to be a qualified
plan under Section 401(a) of the Code has received a favorable determination
letter from the Internal Revenue Service and BOP does not know of any fact which
could adversely affect the qualified status of any such Employee Plan.  All
contributions required to be made to each of the Employee Plans under the terms
of the Employee Plan, ERISA, the Code or any other applicable laws have been
timely made.  The Financial Statements of BOP properly reflect all amounts
required to be accrued as liabilities to date under each of the Employee Plans.
The fair market value of the assets of each Employee Plan and Benefit
Arrangement that is funded, or required to be funded under the terms of the
Employee Plan or Benefit Arrangement, ERISA, the Code or any other applicable
law, equals or exceeds the liabilities, including the present value of benefit
obligations, of such Employee Plan or Benefit Arrangement.

                                      29
<PAGE>

           (e) Except for Scheduled Contracts set forth in the BOP Contract List
or as set forth in the BOP Employee Plan List, as the case may be, each Employee
Plan or Benefit Arrangement and each personal services contract, fringe benefit,
consulting contract or similar arrangement with or for the benefit of any
officer, director, employee or other person can be terminated by BOP within a
period of 30 days following the Effective Time of the Merger, without payment of
any specified amount as a penalty, bonus, premium, severance pay or other
compensation for such termination.

           (f) All group health plans of BOP have been operated in compliance
with the group health plan continuation coverage requirements of Section 4980B
of the Code and with the group health plan portability, access and renewability
requirements of Sections 9801 through 9833 of the Code, and corresponding
provisions of ERISA,  in all material respects.

           (g) BOP has not used the services of (i) workers who have been
provided by a third party contract labor supplier for more than six months or
who may otherwise be eligible to participate in any of the Employee Plans or to
an extent that would reasonably be expected to result in the disqualification of
any of the Employee Plans or the imposition of penalties or excise taxes with
respect to the IRS, the Department of Labor, the Pension Benefit Guaranty
Corporation or any other Governmental Entity; (ii) temporary employees who have
worked for more than six months or who may otherwise be eligible to participate
in any of the Employee Plans or to an extent that would reasonably be expected
to result in the disqualification of any of the Employee Plans or the imposition
of penalties or excise taxes with respect to the IRS, the Department of Labor,
the Pension Benefit Guaranty Corporation or any other Governmental Entity; (iii)
individuals who have provided services to BOP as independent contractors for
more than six months or who may otherwise be eligible to participate in the
Employee Plans or to an extent that would reasonably be expected to result in
the disqualification of any of the Employee Plans or the imposition of penalties
or excise taxes with respect to the IRS, the Department of Labor, the Pension
Benefit Guaranty Corporation or any other Governmental Entity or (iv) leased
employees, as that term is defined in section 414(n) of the Code.

           (h) Except as set forth in the BOP Employee Plan List, with respect
to each Employee Plan that is funded wholly or partially through an insurance
policy, there will be no liability of BOP, as of the Closing Date, under any
such insurance policy or ancillary agreement with respect to such insurance
policy in the nature of a retroactive rate adjustment, loss sharing arrangement
or other actual or contingent liability arising wholly or partially out of
events occurring prior to the Closing Date.

     4.21. Corporate Records.  The minute books of BOP accurately reflect all
           -----------------
material actions taken to this date by the respective shareholders, board of
directors and committees of  BOP.

     4.22. Accounting Records.  BOP maintains accounting records which fairly
           ------------------
and accurately reflect, in all material respects, its transactions and
accounting controls exist sufficient to provide reasonable assurances that such

management's general or specific authorization, and (ii) recorded as necessary
to permit the preparation of financial statements in conformity with generally
accepted

                                      30
<PAGE>

accounting principles.  Such records, to the extent they contain
important information pertaining to BOP which is not easily and readily
available elsewhere, have been duplicated, and such duplicates are stored safely

BOP (including, without limitation, representative and loan production offices
and operations centers) and the location thereof. Except as set forth on the BOP
Offices List, BOP does not maintain any other office or ATM or conducts business
at any other location, and BOP has not applied for or received permission to
open any additional branch or operate at any other location.

     4.24. Operating Losses. BOP has furnished to GBB a list (the "BOP Operating
           ----------------
Losses List") setting forth any Operating Loss (as herein defined) which has
occurred at BOP during the period after December 31, 1998 to the date of the
Agreement. To the best of BOP's knowledge, no action has been taken or omitted
to be taken by any employee of BOP that has resulted in the incurrence by BOP of
an Operating Loss or that might reasonably be expected to result in the
incurrence of any individual Operating Loss which, net of any insurance proceeds
payable in respect thereof, would exceed $50,000 on an individual basis or in
the aggregate. For purposes of this section "Operating Loss" means any loss
resulting from cash shortages, lost or misposted items, disputed clerical and
accounting errors, forged checks, payment of checks over stop payment orders,
counterfeit money, wire transfers made in error, theft, robberies, defalcations,
check kiting, fraudulent use of credit cards or ATMs, civil money penalties,
fines, litigation, claims or other similar acts or occurrences.

     4.25. Loan Portfolio. BOP has furnished to GBB a list (the "BOP Loan List")
           --------------
that sets forth (a) as of January 31, 2000, a description of, by type and
classification, if any, each loan, lease, other extension of credit or
commitment to extend credit by BOP; (b) sets forth as of January 31, 2000, by

if applicable; (iv) the title of issue; and (v) the classification under SFAS

     4.27. Power of Attorney. BOP has not granted any Person a power of attorney
           -----------------
or similar authorization that is presently in effect or outstanding.

     7.9. Stock Options.
          -------------

          (a) At and as of the Effective Time of the Merger, GBB shall assume
each and every outstanding option to purchase shares of BOP Stock ("BOP Stock
Option") under the BOP Stock Option Plan.  Subject to Section 7.9(d), each and
every BOP Stock Option so assumed by GBB under this Agreement shall be exchanged
for a substitute option under the GBB Stock Option Plan with the following
terms: (i) such BOP Stock Option shall be exercisable for that number of whole
shares of GBB Stock equal to the product of (A) the number of shares of BOP
Stock that were granted under such BOP Stock Option immediately prior to the
Effective Time of the Merger (the vesting of which will be accelerated in
accordance with the terms of the BOP Stock Option Plan and the agreements
pursuant thereto) multiplied by (B) the Conversion Ratio, with such product
rounded down to the nearest whole number of shares of GBB Stock; and (ii) the
per share exercise price for the shares of GBB Stock issuable upon exercise of
such BOP Stock Option shall be equal to the quotient determined by dividing (A)
the exercise price per share of BOP Stock at which such BOP Stock Option was
exercisable immediately prior to the Effective Time of the Merger by (B) the
Conversion Ratio.  After the Effective Time of the Merger, GBB shall issue to
each holder of an outstanding BOP Stock Option a document evidencing the
substitute option pursuant to this Section 7.9.

          (b) The terms of the substitute options shall correspond in all
material respects to the terms of the BOP Stock Options and, subject to the
requirements of law, the BOP Stock Options which qualify as incentive stock
options prior to the Effective Time of the Merger qualify as incentive stock
options of GBB after the Effective Time of the Merger.

          (c) At or prior to the Effective Time of the Merger, GBB shall take
all corporate action necessary to reserve for issuance a sufficient number of
shares of GBB Stock for delivery upon exercise of GBB Stock Options assumed by
it in accordance with this Section 7.9.  At the Effective Time of the Merger, or
as soon as practicable thereafter, GBB shall, if necessary, file a registration
statement on Form S-8 (or any successor or other appropriate form) with respect
to the shares of GBB Stock subject to such options and shall use all reasonable
efforts to maintain the effectiveness of such registration statement (and
maintain the current status of the prospectus or prospectuses contained therein)
for so long as such options remain outstanding.

          (d) In the event the shareholders of GBB fail to approve an increase
in the number of shares reserved for issuance under the GBB Stock Option Plan at
the shareholders' meeting to be held in connection with the merger of GBB and
Coast Bancorp, GBB will assume the BOP Stock Option Plan and each BOP Stock
Option granted thereunder.  Each such BOP Stock Option so assumed by GBB under
this Agreement shall continue to have, and be subject to, the same terms and
conditions set forth in the BOP Stock Option Plan and in the other documents
governing such BOP Stock Option immediately prior to the Effective Time of the
Merger; provided, however, that such BOP Stock Options will be exercisable for
that number of shares of GBB Stock computed in accordance with Section 7.9(a)(i)
and (ii).  In such event, the BOP Stock Option Plan (as amended, if necessary,
to provide for the exchange of GBB Stock for BOP Stock upon the exercise of BOP
Stock Options) will continue in effect for the BOP Stock Options so assumed.

determined to be prudent by GBB, in its sole discretion, and, unless the
estimated cost of such remediation is in excess of $100,000 or is not reasonably
determinable by such consultant (and written notice thereof provided by BOP to
GBB) BOP shall immediately commence such remediation, all at the

determines that the estimated cost of such remediation is in excess of $100,000
or is not reasonably determinable, GBB shall have the right to terminate the
Agreement pursuant to Section 13.1(k) hereof before the expiration of 21 days
from the date of such written notice.

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

Effective Time of the Merger, or to merge the BOP 401(k) Plan with and into the

merge the  BOP 401(k) Plan into the GBB 401(k) Plan and that the BOP 401(k) Plan
should be terminated immediately prior to the Effective Time of the Merger, BOP
agrees to use its best efforts to have the BOP 401(k) Plan terminated prior to
the Effective Time of the Merger and to obtain an IRS determination that the BOP
401(k) Plan continues to be qualified upon termination.

     As soon as practicable after the Effective Time of the Merger, all other
Employee Plans will be discontinued or merged into GBB plans, in the discretion
of GBB, and employees of BOP shall become eligible for the employee benefit
plans of GBB on the same terms as such plans and benefits are generally offered
from time to time to employees of GBB and its subsidiaries in comparable
positions with GBB or its subsidiaries.  For purposes of determining such
employment eligibility and vesting under the employee benefit plans of GBB, GBB
shall recognize such employees' years of service with BOP beginning on the date
such employees commenced employment with BOP through the Effective Time of the
Merger.

                            GREATER BAY BANCORP AND
                 BANK OF PETALUMA ANNOUNCE AGREEMENT TO MERGE
                 --------------------------------------------

PALO ALTO, CA; March 21, 2000 -- Greater Bay Bancorp (Nasdaq:GBBK), Palo Alto,
California, and Bank of Petaluma (OTC Bulletin Board:BPLU), Petaluma,
California, announced today the signing of a definitive merger agreement.  Upon
completion of the merger, Bank of Petaluma will operate as a wholly owned
subsidiary of Greater Bay Bancorp.

In the merger, Greater Bay Bancorp will issue shares of its stock in a tax free
exchange for the shares of stock of Bank of Petaluma for an estimated value of
approximately $41 million, depending on the market price of Greater Bay
Bancorp's stock at the time of the merger closing.  Based on Greater Bay
Bancorp's closing price on March 21, 2000 of $39 3/8, Bank of Petaluma
shareholders would receive a price equating to a multiple of 17.8 times Bank of
Petaluma's last 12 months earnings and 2.76 times Bank of Petaluma's book value
at December 31, 1999.   The merger, which will be accounted for as a pooling of
interests, is expected to be completed in the third quarter of 2000.

Greater Bay Bancorp anticipates the transaction, including cost savings, to be
approximately 1% accretive to 2000 earnings per share.  Greater Bay Bancorp has
not included any anticipated revenue enhancements that may be realized from the
merger, even though Greater Bay Bancorp's prior acquisitions have resulted in
significant revenue growth.

Bank of Petaluma, founded in 1987, is situated in the growing area of the San
Francisco Bay Area's northern market  known as the "Telecom Valley."  This area
includes start-up and seasoned companies specializing in the burgeoning
telecommunications industry.  Bank of Petaluma maintains four banking offices in
Petaluma, Point Reyes Station and Valley Ford, California and serves the small-
to mid-sized business community and retail banking clients.  As of December 31,
1999, Bank of Petaluma had total assets of $194.7 million and deposits of $162.2
million.   For the year ended December 31, 1999, net income was $2.3 million, a
10% increase over net income of $2.1 million in 1998.

David Kalkbrenner, President and Chief Executive Officer of Greater Bay Bancorp,
stated, "Bank of Petaluma meets our merger criteria of a high performing bank
with strong management located
<PAGE>

in a high growth area. On several occasions, Greater Bay's Venture Banking Group
has participated in loans in the Telecom Valley and will continue to pursue
those opportunities with the strong foothold Bank of Petaluma has developed in
its market area." Mr. Kalkbrenner added, "We look forward to becoming active
members of the North Bay community through the support which the Greater Bay
Bancorp Foundation will provide to community and philanthropic organizations in
the area. When the merger closes, we will also be pleased to welcome Daniel G.
Libarle, Chairman of Bank of Petaluma, to our Board of Directors."

"We found the super community banking philosophy of Greater Bay Bancorp uniquely
attractive," said Daniel G. Libarle, Chairman of the Bank of Petaluma.  "This is
a proven successful formula which preserves the name of Bank of Petaluma, our
Board and our management while providing the expanded resources of Greater Bay
Bancorp."

Walter E. Bragdon, President and Chief Executive Officer of Bank of Petaluma,
commented, "We have developed a loyal client base over the years among the
agricultural and small business communities in our markets.  Bank of Petaluma
will continue to focus on real estate, business and consumer lending and our
clients will benefit from the increased lending limit and expanded services Bank
of Petaluma will be able to offer as part of the Greater Bay family.  We also
believe the merger is in the best interests of our shareholders, as they will
receive greater liquidity in a stock that is a component of the Nasdaq
Financial-100 Index."

Greater Bay Bancorp previously announced the execution of definitive agreements
to merge with Coast Bancorp and Bank of Santa Clara.  When these mergers and the
Bank of Petaluma merger are all completed, Greater Bay Bancorp would have had,
on a pro forma basis as of December 31, 1999, total assets of approximately $3.7
billion, total shareholders' equity of approximately $253 million, total loans
of approximately $2.5 billion and total deposits of approximately $3.3 billion.
Greater Bay Bancorp's net income (before merger expenses, nonrecurring costs and
extraordinary items) on a pro forma basis as of December 31, 1999 would have
been approximately $51 million.

With the addition of Bank of Petaluma, Greater Bay Bancorp will have banks
located in the North Bay, San Francisco Peninsula, South Bay, East Bay and
Coastal regions of the Greater San Francisco Bay Area.

Terms of the Merger
The terms of the agreement provide for the shareholders of Bank of Petaluma to
receive shares of Greater Bay Bancorp stock.  Bank of Petaluma currently has
approximately 1.4 million shares of common stock outstanding.  If the average
closing price of Greater Bay Bancorp common stock is between $37.91 and $46.34,
each share of Bank of Petaluma stock will be exchanged for 0.685 shares of
Greater Bay Bancorp stock.

If the average closing price of Greater Bay Bancorp common stock is greater than
$46.34, the exchange ratio will decrease by dividing the average closing price
into $31.74 plus one-third of the amount by which the average closing price
exceeds $46.34.

If the average closing price of Greater Bay Bancorp common stock is less than
$37.91, Greater Bay Bancorp may elect to exercise a top up option.  In that
case, the exchange ratio will equal the

                                      66
<PAGE>

quotient obtained by dividing $25.97 by the average closing price of Greater Bay
Bancorp stock. If Greater Bay Bancorp does not elect the top up option, Bank of
Petaluma may either terminate the merger agreement or accept an exchange ratio
of 0.685.

The merger is subject to certain conditions, including the approval of the
shareholders of Bank of Petaluma and regulatory approval.  Upon consummation of
the merger, former Bank of Petaluma shareholders will own approximately 4.7% of
Greater Bay Bancorp's outstanding shares, assuming completion of the previously
announced Greater Bay Bancorp mergers with Coast Bancorp and Bank of Santa
Clara.

Greater Bay Bancorp through its seven subsidiary banks, Bay Area Bank, Bay Bank
of Commerce, Cupertino National Bank, Golden Gate Bank, Mid-Peninsula Bank, Mt.
Diablo National Bank and Peninsula Bank of Commerce, along with its operating
divisions, serves clients throughout Silicon Valley, San Francisco, the San
Francisco Peninsula, and the Contra Costa Tri Valley Region, with offices
located in Cupertino, Danville, Fremont, Hayward, Lafayette, Millbrae, Palo
Alto, Pleasanton, Redwood City, San Francisco, San Jose, San Leandro, San Mateo,
San Ramon, Santa Clara, and Walnut Creek.
