The    % Cumulative Trust Preferred Securities (the "Trust Preferred
Securities") offered hereby represent undivided beneficial interests in the
assets of GBB Capital I, a statutory business trust formed under the laws of
the State of Delaware ("GBB Capital"). Greater Bay Bancorp, a California
corporation (referred to as the "Company" when such reference includes Greater
Bay Bancorp and its subsidiaries, collectively, or "Greater Bay" when referring
only to the parent company), will be the owner of all of the beneficial
interests represented by common securities of GBB Capital (the "Common
Securities" and, collectively with the Trust Preferred Securities, the "Trust
Securities"). GBB Capital exists for the sole purpose of issuing the Trust
Securities and investing the proceeds thereof in    % Junior Subordinated
Deferrable Interest Debentures (the "Junior Subordinated Debentures") to be
issued by Greater Bay. The Junior Subordinated Debentures will mature on
        , 2027, which date may be shortened (such date, as it may be shortened,
the "Stated Maturity") to a date not earlier than         , 2002 if certain
conditions are met (including Greater Bay having received prior approval of the
Board of Governors of the Federal Reserve System (the "Federal Reserve") to do
so if then required under applicable capital guidelines or policies of the
Federal Reserve). The Trust Preferred Securities will have a preference under
certain circumstances with respect to cash distributions and amounts payable on
liquidation, redemption or otherwise over the Common Securities, which will be
held by Greater Bay. See "Description of the Trust Preferred Securities--
Subordination of Common Securities of GBB Capital Held by Greater Bay."

(1) Greater Bay and GBB Capital have agreed to indemnify the Underwriter
    against certain liabilities, including liabilities under the Securities Act
    of 1933, as amended the ("Securities Act"). See "Underwriting."
(2) In view of the fact that all of the proceeds of the sale of the Trust
    Preferred Securities will be used to purchase the Junior Subordinated
    Debentures, Greater Bay has agreed to pay the Underwriters as compensation
    for arranging the investment therein of such proceeds, $    per Trust
    Preferred Security, or $      in the aggregate. See "Underwriting."
(3) Before deducting offering expenses payable by Greater Bay estimated at
    $359,000.
 
The Trust Preferred Securities are being offered by the Underwriter named
herein subject to prior sale and when, as and if delivered to and accepted by
the Underwriter. It is expected that the Trust Preferred Securities will be
ready for delivery in book-entry form only through the facilities of The
Depository Trust Company in New York, New York, on or about              ,
1997, against payment therefor in immediately available funds.

(Continued from previous page)
 
Holders of the Trust Preferred Securities will be entitled to receive
preferential cumulative cash distributions accruing from the date of original
issuance and payable quarterly in arrears on the 15th day of March, June,
September and December of each year (subject to possible deferral as described
below), commencing June 15, 1997, at the annual rate of    % of the
Liquidation Amount (as defined herein) of $25 per Trust Preferred Security
("Distributions"). The amount of each Distribution due with respect to the
Trust Preferred Securities will include amounts accrued through the date the
Distribution payment is due. Greater Bay will have the right to defer payments
of interest on the Junior Subordinated Debentures at any time or from time to
time for a period not exceeding 20 consecutive quarters with respect to each
deferral period (each, an "Extension Period"), provided that no Extension
Period may extend beyond the Stated Maturity of the Junior Subordinated
Debentures. Upon the termination of any such Extension Period and the payment
of all amounts then due, Greater Bay may elect to begin a new Extension Period
subject to the requirements set forth herein. If interest payments on the
Junior Subordinated Debentures are so deferred, Distributions on the Trust
Preferred Securities will also be deferred and Greater Bay will not be
permitted, subject to certain exceptions described herein, to declare or pay
any cash distributions with respect to its capital stock or to make any
payment with respect to its debt securities that rank pari passu with or
junior to the Junior Subordinated Debentures. During an Extension Period,
interest on the Junior Subordinated Debentures will continue to accrue (and
the amount of Distributions to which holders of the Trust Preferred Securities
are entitled will accumulate) at the rate of    % per annum, compounded
quarterly, and holders of the Trust Preferred Securities will be required to
accrue income and will be required to pay United States federal income tax on
that income. See "Description of Junior Subordinated Debentures--Option to
Defer Interest Payment Period" and "Certain Federal Income Tax Consequences--
Interest Income and Original Issue Discount."
 
Greater Bay has, through the Guarantee, the Guarantee Agreement, the Trust
Agreement, the Junior Subordinated Debentures, the Indenture and the Expense
Agreement (each as defined herein), taken together, fully, irrevocably and
unconditionally guaranteed all of GBB Capital's obligations under the Trust
Preferred Securities. See "Relationship Among the Trust Preferred Securities,
the Junior Subordinated Debentures and the Guarantee--Full and Unconditional
Guarantee." Under the Guarantee, Greater Bay guarantees the payment of
Distributions by GBB Capital and payments on liquidation of or redemption of
the Trust Preferred Securities (subordinate to the right to payment of Senior
and Subordinated Debt of Greater Bay, as defined herein) to the extent of
funds held by GBB Capital. The Guarantee does not cover payment of
Distributions when GBB Capital does not have sufficient funds to pay such
Distributions. See "Description of Guarantee." If Greater Bay does not make
required payments on the Junior Subordinated Debentures held by GBB Capital,
GBB Capital will have insufficient funds to pay Distributions on the Trust
Preferred Securities. In such event, a holder of the Trust Preferred
Securities may institute a legal proceeding directly against Greater Bay
pursuant to terms of the Indenture to enforce payment of such Distributions to
such holder. See "Description of Junior Subordinated Debentures--Enforcement
of Certain Rights by Holders of the Trust Preferred Securities." The
obligations of Greater Bay under the Guarantee and the Junior Subordinated
Debentures are subordinate and junior in right of payment to all Senior and
Subordinated Debt (as defined in "Description of Junior Subordinated
Debentures--Subordination") of Greater Bay.
 
The Trust Preferred Securities are subject to mandatory redemption, in whole
or in part, upon repayment of the Junior Subordinated Debentures at the Stated
Maturity or their earlier redemption in each case at a redemption price equal
to the aggregate liquidation preference of the Trust Preferred Securities plus
any accumulated and unpaid Distributions thereon to the date of redemption.
The Junior Subordinated Debentures are redeemable prior to maturity at the
option of Greater Bay, subject to any required prior approval of the Federal
Reserve, (i) on or after        , 2002, in whole at any time or in part from
time to time, or (ii) at any time, in whole (but not in part), upon the
occurrence and continuation of a Tax Event, an Investment Company Event or a
Capital Treatment Event (each as defined herein), in each case at a redemption
price equal to the accrued and unpaid interest on the Junior Subordinated
Debentures to the date fixed for redemption, plus 100% of the principal amount
thereof. See "Description of the Trust Preferred Securities--Redemption."
 
 
                                                       (Continued on next page)
 
                                       2

(Continued from previous page)
 
Greater Bay will have the right at any time to terminate GBB Capital and cause
a Like Amount (as defined herein) of the Junior Subordinated Debentures to be
distributed to the holders of the Trust Securities in liquidation of GBB
Capital, subject to Greater Bay having received prior approval of the Federal
Reserve if then required under applicable capital guidelines or policies of
the Federal Reserve. See "Description of the Trust Preferred Securities--
Liquidation Distribution upon Termination."
 
The Junior Subordinated Debentures are unsecured and subordinated to all
Senior and Subordinated Debt. As of December 31, 1996, Greater Bay had
approximately $3.0 million aggregate principal amount of Senior and
Subordinated Debt outstanding. The terms of the Junior Subordinated Debentures
place no limitation on the amount of Senior and Subordinated Debt that Greater
Bay can issue. See "Risk Factors--Ranking of Greater Bay's Obligations Under
the Junior Subordinated Debentures and the Guarantee" and "Description of
Junior Subordinated Debentures--Subordination."
 
In the event of the termination of GBB Capital, after satisfaction of
liabilities to creditors of GBB Capital as required by applicable law, the
holders of Trust Preferred Securities will be entitled to receive a
liquidation amount of $25 per Trust Preferred Security ("Liquidation Amount"),
plus accumulated and unpaid Distributions thereon to the date of payment,
which may be in the form of a Distribution of such Like Amount of Junior
Subordinated Debentures, subject to certain exceptions. See "Description of
the Trust Preferred Securities--Liquidation Distribution Upon Termination."
 
Application has been made to list the Trust Preferred Securities on the Nasdaq
National Market. Although the Underwriter has indicated an intention to make a
market in the Trust Preferred Securities, the Underwriter is not obligated to
make a market in the Trust Preferred Securities, and any market making may be
discontinued at any time at the sole discretion of the Underwriter. There can
be no assurance that a market will develop for the Trust Preferred Securities.
See "Risk Factors--Absence of Existing Public Market; Market Prices" and
"Underwriting."
 
The Trust Preferred Securities will be represented by one or more global
certificates registered in the name of The Depository Trust Company (the
"Depositary") or its nominee. Beneficial interests in the Trust Preferred
Securities will be shown on, and transfers thereof will be effected only
through, records maintained by participants in the Depositary. Except as
described herein, the Trust Preferred Securities in certificate form will not
be issued in exchange for global certificates. See "Book-Entry Issuance."

                                  THE COMPANY
 
  Greater Bay is a bank holding company operating Cupertino National Bank &
Trust ("CNB") and Mid-Peninsula Bank (separately, "MPB" and together with CNB,
the "Banks") with seven regional offices in Cupertino, Palo Alto, San Mateo,
San Carlos and San Jose, California. Greater Bay is the result of the merger
(the "Merger"), effective November 27, 1996, of Cupertino National Bancorp
("Cupertino") and Mid-Peninsula Bancorp ("Mid-Peninsula"). At December 31,
1996, the Company had total assets of $622.0 million, total net loans of
$441.6 million and total deposits of $559.3 million.
 
  The Company, through the Banks, provides a wide range of commercial banking
services to small and medium-sized businesses, real estate developers and
property managers, business executives, professionals and other individuals,
primarily in the Santa Clara and San Mateo Counties of California. Services
include personal and business checking and savings accounts, time deposits and
individual retirement accounts, cash management, international trade services
and accounting services and the making of commercial, consumer and real estate
loans, which generally do not include long-term residential mortgage loans.
Additionally, the Company offers several specialized services including a
Small Business Administration ("SBA") Department which makes SBA guaranteed
loans to assist smaller businesses, a venture lending division (the "Venture
Lending Group") that services companies in their start-up and development
phase and a trust department (the "Greater Bay Trust Company") that offers a
full range of fee-based trust services directly to its clients.
 
  In order to meet the demands of the increasingly competitive banking and
financial services industries, management has adopted a business philosophy
referred to as the "Super Community Banking Philosophy." The Super Community
Banking Philosophy is based on management's belief that banking customers
value doing business with locally managed institutions that can provide a full
service commercial banking relationship through an understanding of the
customer's financial needs and the flexibility to customize products and
services to meet those needs. Management further believes that banks are
better able to build successful customer relationships by affiliating with a
holding company that provides cost effective administrative support services
while promoting bank autonomy and flexibility.
 
  To implement this philosophy, Greater Bay operates CNB and MPB as separate
subsidiaries by retaining their independent names along with their individual
Boards of Directors. Both MPB and CNB have established strong reputations and
customer followings in their respective market areas through attention to
client service and an understanding of client needs. In an effort to
capitalize on the identities and reputations of the Banks, the Company will
continue to market its services under the CNB and MPB names, primarily through
each Bank's relationship managers. The primary focus for the Banks'
relationship managers is to cultivate and nurture their client relationships.
Relationship managers are assigned to each borrowing client to provide
continuity in the relationship. This emphasis on personalized relationships
requires that all of the relationship managers maintain close ties to the

- -------------------------------------------------------------------------------
communities in which they serve, so they are able to capitalize on their
efforts through expanded business opportunities for the Banks.
 
  While client service decisions and day-to-day operations are maintained at
the Banks, Greater Bay offers the advantages of affiliation with a multi-bank
holding company by providing improved access to the capital markets and
expanded client support services, such as business cash management,
international trade services and accounting services. In addition, Greater Bay
provides centralized administrative functions, including support in credit
policy formulation and review, investment management, data processing,
accounting and other specialized support functions thereby allowing the Banks
to focus on client service.
 
  The Company's business strategy is to focus on increasing its market share
within the communities it serves through continued internal growth. As a
result of the Merger, the Company has the opportunity to market the
specialized products and services of the Venture Lending Group, the Greater
Bay Trust Company and the SBA Department to a larger customer base. The
Company believes that these products and services, available prior to the
Merger only to customers of CNB, will be attractive to customers and contacts
of MPB in the venture capital community and the high net worth customers of
MPB. The Company believes that the infrastructure developed by Cupertino to
support the Greater Bay Trust Company, the SBA Department and the Venture
Lending Group will allow the Company to offer the products and services of
these groups without significant additional overhead costs.
 
  The Company also will pursue opportunities to expand its market share
through select acquisitions that management believes complement the Company's
businesses. While management would prefer to make acquisitions which would
expand its presence in its current market areas in Santa Clara and San Mateo
Counties, it will also pursue opportunities to expand its market through
acquisitions in other parts of the South, East, and North Bay Areas of San
Francisco.
 
  The Company was incorporated in California in 1984 under the name San Mateo
County Bancorp. See "Business--History." The Company's principal offices are
located at 2860 West Bayshore Road, Palo Alto, California 94303 and its
telephone number is (415) 813-8200.
 
                                  GBB CAPITAL
 
  GBB Capital is a statutory business trust formed under Delaware law pursuant
to (i) the Trust Agreement and (ii) the filing of a Certificate of Trust with
the Delaware Secretary of State on March 3, 1997. GBB Capital's business and
affairs are conducted by the Property Trustee, Delaware Trustee and three
individual Administrative Trustees who are officers of the Company. GBB
Capital exists for the exclusive purposes of (i) issuing and selling the Trust
Securities, (ii) using the proceeds from the sale of the Trust Securities to
acquire the Junior Subordinated Debentures issued by Greater Bay, and (iii)
engaging in only those other activities necessary, advisable or incidental
thereto (such as registering the transfer of the Trust Securities).
Accordingly, the Junior Subordinated Debentures will be the sole assets of GBB
Capital, and payments by Greater Bay under the Junior Subordinated Debentures
and the Expense Agreement will be the sole revenues of GBB Capital. All of the
Common Securities will be owned by Greater Bay. The Common Securities will
rank pari passu, and payments will be made thereon pro rata, with the Trust
Preferred Securities, except that upon the occurrence and during the
continuance of an event of default under the Trust Agreement resulting from an
event of default under the Indenture, the rights of Greater Bay as holder of
the Common Securities to payment in respect of Distributions and payments upon
liquidation, redemption or otherwise will be subordinated to the rights of the
holders of the Trust Preferred Securities. See "Description of the Trust
Preferred Securities--Subordination of Common Securities of GBB Capital Held
by Greater Bay." Greater Bay will acquire Common Securities in an aggregate
liquidation amount equal to 3.0% of the total capital of GBB Capital. GBB
Capital has a term of 31 years, but may terminate earlier as provided in the
Trust Agreement.
 
  GBB Capital's principal offices are located at 2860 West Bayshore Road, Palo
Alto, California 94303 and its telephone number is (415) 813-8200.

                                    Distribution due with respect to the Trust
                                    Preferred Securities will include amounts
                                    accrued through the date the Distribution

                                    Trust Preferred Securities--Distributions."

 Extension periods................  So long as no Debenture Event of Default
                                    (as defined herein) has occurred and is
                                    continuing, Greater Bay will have the
                                    right, at any time, to defer payments of
                                    interest on the Junior Subordinated
                                    Debentures by extending the interest
                                    payment period thereon for a period not
                                    exceeding 20 consecutive quarters with
                                    respect to each deferral period (each an
                                    "Extension Period"), provided that no
                                    Extension Period may extend beyond the
                                    Stated Maturity of the Junior Subordinated
                                    Debentures. If interest payments are so
                                    deferred, Distributions on the Trust
                                    Preferred Securities will also be deferred
                                    and Greater Bay will not be permitted,
                                    subject to certain exceptions described
                                    herein, to declare or pay any cash
                                    distributions with respect to Greater Bay's
                                    capital stock or debt securities that rank
                                    pari passu with or junior to the Junior
                                    Subordinated Debentures. During an
                                    Extension Period, Distributions will
                                    continue to accumulate with income thereon
                                    compounded quarterly. Because interest
                                    would continue to accrue and compound on
                                    the Junior Subordinated Debentures, to the
                                    extent permitted by applicable law, holders
                                    of the Trust Preferred Securities will be
                                    required to accrue income for United States
                                    federal income tax purposes. See
                                    "Description of Junior Subordinated

                                    not earlier than         , 2002 if certain

                                    having received prior approval of the
                                    Federal Reserve to do so if then required

                                    as described under "Description of the

                                    Subordinated Debt, the amount of which is
                                    unlimited. At December 31, 1996, the
                                    aggregate outstanding Senior and
                                    Subordinated Debt of Greater Bay was
                                    approximately $3.0 million. In addition,
                                    because Greater Bay is a holding company,
                                    all obligations of Greater Bay relating to
                                    the securities described herein will be
                                    effectively subordinated to all existing
                                    and future liabilities of Greater Bay's
                                    subsidiaries, including the Banks. Greater
                                    Bay may cause additional Trust Preferred

                                    to GBB Capital in the future, and there is
                                    no limit on the amount of such securities
                                    that may be issued. In this event, Greater
                                    Bay's obligations under the Junior
                                    Subordinated Debentures to be issued to
                                    such other trusts and Greater Bay's
                                    guarantees of the payments by such trusts
                                    will rank pari passu with Greater Bay's
                                    obligations under the Junior Subordinated
                                    Debentures and the Guarantee, respectively.

 Voting rights....................  The holders of the Trust Preferred
                                    Securities will generally have limited
                                    voting rights relating only to the

                                    hereby will be invested by GBB Capital in
                                    the Junior Subordinated Debentures of
                                    Greater Bay. Greater Bay intends to invest
                                    approximately $10.0 million of the net
                                    proceeds in the Banks to increase their
                                    capital levels to support future growth.
                                    Greater Bay intends to use the remaining
                                    net proceeds for general corporate
                                    purposes, which may include without
                                    limitation, funding additional investments
                                    in, or extensions of credit to, the Banks,
                                    and possible future acquisitions. Greater
                                    Bay expects the Trust Preferred Securities
                                    to qualify as Tier 1 capital under the
                                    capital guidelines of the Federal Reserve.

                                 RISK FACTORS
 
  Prospective investors should consider, among other things, the following
factors in connection with a decision to purchase the Trust Preferred
Securities.
 
RANKING OF GREATER BAY'S OBLIGATIONS UNDER THE JUNIOR SUBORDINATED DEBENTURES
AND THE GUARANTEE
 
  All obligations of Greater Bay under the Guarantee, the Junior Subordinated
Debentures and other documents described herein are unsecured and rank
subordinate and junior in right of payment to all current and future Senior
and Subordinated Debt, the amount of which is unlimited. At December 31, 1996,
the aggregate outstanding Senior and Subordinated Debt of Greater Bay was
approximately $3.0 million. In addition, because Greater Bay is a holding
company, all obligations of Greater Bay relating to the securities described
herein will be effectively subordinated to all existing and future liabilities
of Greater Bay's subsidiaries, including the Banks. As a holding company, the
right of Greater Bay to participate in any distribution of assets of any
subsidiary upon such subsidiary's liquidation or reorganization or otherwise
(and thus the ability of holders of the Trust Preferred Securities to benefit
indirectly from such distribution) is subject to the prior claims of creditors
of that subsidiary, except to the extent that Greater Bay may itself be
recognized as a creditor of that subsidiary. Accordingly, the Junior
Subordinated Debentures and all obligations of Greater Bay relating to the
Trust Preferred Securities will be effectively subordinated to all existing
and future liabilities of the Banks, and holders of the Trust Preferred
Securities should look only to the assets of Greater Bay, and not of its
subsidiaries, for principal and interest payments on the Junior Subordinated
Debentures. None of the Indenture, the Guarantee, the Guarantee Agreement or
the Trust Agreement places any limitation on the amount of secured or
unsecured debt, including Senior and Subordinated Debt, that may be incurred
by Greater Bay or its subsidiaries. Further, there is no limitation on Greater
Bay's ability to issue additional Junior Subordinated Debentures in connection
with any further offerings of Trust Preferred Securities, and such additional
debentures would rank pari passu with the Junior Subordinated Debentures. See
"Description of Junior Subordinated Debentures--Subordination" and
"Description of Guarantee--Status of the Guarantee."
 
DEPENDENCE ON DIVIDENDS AND INTEREST PAYMENTS FROM THE BANKS
 
  The ability of GBB Capital to pay amounts due on the Trust Preferred
Securities is solely dependent upon Greater Bay making payments on the Junior
Subordinated Debentures as and when required. As a holding company without
significant assets other than its equity interest in the Banks, Greater Bay's
ability to pay interest on the Junior Subordinated Debentures to GBB Capital
(and consequently GBB Capital's ability to pay Distributions on the Trust
Preferred Securities and Greater Bay's ability to pay its obligations under
the Guarantee) depends primarily upon the cash dividends Greater Bay receives
from the Banks. Dividend payments from the Banks are subject to regulatory
limitations, generally based on current and retained earnings, imposed by the
various regulatory agencies with authority over the respective Banks. Payment
of dividends is also subject to regulatory restrictions if such dividends
would impair the capital of the Banks. Payment of dividends by the Banks is
also subject to the respective Bank's profitability, financial condition and
capital expenditures and other cash flow requirements. No assurance can be
given that the Banks will be able to pay dividends at past levels, or at all,
in the future. See "Supervision and Regulation."
 
OPTION TO DEFER INTEREST PAYMENT PERIOD; TAX CONSEQUENCES OF A DEFERRAL OF
INTEREST PAYMENTS
 
  So long as no Debenture Event of Default (as defined herein) has occurred
and is continuing, Greater Bay has the right under the Indenture to defer
payment of interest on the Junior Subordinated Debentures at any time or from
time to time for a period not exceeding 20 consecutive quarters with respect
to each Extension Period, provided that no Extension Period may extend beyond
the Stated Maturity of the Junior Subordinated Debentures. As a consequence of
any such deferral, quarterly Distributions on the Trust Preferred Securities
by GBB Capital will be deferred (and the amount of Distributions to which
holders of the Trust Preferred Securities are entitled will accumulate
additional amounts thereon at the rate of      % per annum, compounded
quarterly, from the relevant payment date for such Distributions, to the
extent permitted by applicable law) during any such
 
                                      11
<PAGE>
 
Extension Period. During any such Extension Period, Greater Bay will be
prohibited from making certain payments or distributions with respect to
Greater Bay's capital stock (including dividends on or redemptions of common
or preferred stock) and from making certain payments with respect to any debt
securities of Greater Bay that rank pari passu with or junior in interest to
the Junior Subordinated Debentures; however, Greater Bay will not be
restricted from (a) paying dividends or distributions in common stock of
Greater Bay, (b) redeeming rights or taking certain other actions under a
shareholders' rights plan, (c) making payments under the Guarantee or (d)
making purchases of common stock related to the issuance of common stock or
rights under any of Greater Bay's benefit plans for its directors, officers or
employees. Further, during an Extension Period, Greater Bay would have the
ability to continue to make payments on Senior and Subordinated Debt. Prior to
the termination of any Extension Period, Greater Bay may further extend such
Extension Period provided that such extension does not cause such Extension
Period to exceed 20 consecutive quarters or to extend beyond the Stated
Maturity. Upon the termination of any Extension Period and the payment of all
interest then accrued and unpaid (together with interest thereon at the annual
rate of      %, compounded quarterly, to the extent permitted by applicable
law), Greater Bay may elect to begin a new Extension Period subject to the
above requirements. There is no limitation on the number of times that Greater
Bay may elect to begin an Extension Period. See "Description of the Trust
Preferred Securities--Distributions" and "Description of Junior Subordinated
Debentures--Option to Defer Interest Payment Period."
 
  Because Greater Bay believes the likelihood of it exercising its option to
defer payments of interest is remote, the Junior Subordinated Debentures will
be treated as issued without "original issue discount" for United States
federal income tax purposes. As a result, holders of Trust Preferred
Securities will include interest in taxable income under their own methods of
accounting (i.e., cash or accrual). If Greater Bay exercises its right to
defer payments of interest, the holders of Trust Preferred Securities will be
required to include their pro rata share of original issue discount in gross
income as it accrues for United States federal income tax (and possibly other)
purposes in advance of the receipt of cash. See "Certain Federal Income Tax
Consequences-- Interest Income and Original Issue Discount." Greater Bay has
no current intention of exercising its right to defer payments of interest by
extending the interest payment period on the Junior Subordinated Debentures.
However, should Greater Bay elect to exercise its right to defer payments of
interest in the future, the market price of the Trust Preferred Securities is
likely to be adversely affected. A holder that disposes of such holder's Trust
Preferred Securities during an Extension Period, therefore, might not receive
the same return on such holder's investment as a holder that continues to hold
the Trust Preferred Securities.
 
TAX EVENT REDEMPTION, INVESTMENT COMPANY ACT REDEMPTION OR CAPITAL TREATMENT
EVENT REDEMPTION
 
  Upon the occurrence and during the continuation of a Tax Event, an
Investment Company Event or a Capital Treatment Event (whether occurring
before or after     , 2002), Greater Bay has the right, if certain conditions
are met, to redeem the Junior Subordinated Debentures in whole (but not in
part) at 100% of the principal amount together with accrued but unpaid
interest to the date fixed for redemption within 90 days following the
occurrence of such Tax Event, Investment Company Event or Capital Treatment
Event and therefore cause a mandatory redemption of the Trust Securities. The
exercise of such right is subject to Greater Bay having received prior
approval of the Federal Reserve to do so if then required under applicable
guidelines or policies of the Federal Reserve. See "Description of the Trust
Preferred Securities--Redemption."
 
  A "Tax Event" means the receipt by Greater Bay and GBB Capital of an opinion
of counsel experienced in such matters to the effect that, as a result of any
amendment to, or change (including any announced prospective change) in, the
laws (or any regulations thereunder) of the United States or any political
subdivision or taxing authority thereof or therein, or as a result of any
official administrative pronouncement or judicial decision interpreting or
applying such laws or regulations, which amendment or change is effective or
such prospective change, pronouncement or decision is announced on or after
the original issuance of the Trust Preferred Securities, there is more than an
insubstantial risk that (i) GBB Capital is, or will be within 90 days of the
date of such opinion, subject to United States federal income tax with respect
to income received or accrued
 
                                      12
<PAGE>
 
on the Junior Subordinated Debentures, (ii) interest payable by Greater Bay on
the Junior Subordinated Debentures is not, or within 90 days of such opinion,
will not be, deductible by Greater Bay, in whole or in part, for United States
federal income tax purposes, or (iii) GBB Capital is, or will be within 90
days of the date of the opinion, subject to more than a de minimus amount of
other taxes, duties or other governmental charges. See "--Possible Tax Law
Changes Affecting the Trust Preferred Securities" below for a discussion of
certain legislative proposals that, if adopted, could give rise to a Tax
Event, which may permit Greater Bay to cause a redemption of the Junior
Subordinated Debentures (and therefore the Trust Preferred Securities) prior
to     , 2002.
 
  An "Investment Company Event" means the receipt by Greater Bay and GBB
Capital of an opinion of counsel experienced in such matters to the effect
that, as a result of any change in law or regulation or a change in
interpretation or application of law or regulation by any legislative body,
court, governmental agency or regulatory authority, GBB Capital is or will be
considered an "investment company" that is required to be registered under the
Investment Company Act, which change becomes effective on or after the
original issuance of the Trust Preferred Securities.
 
  A "Capital Treatment Event" means the reasonable determination by Greater
Bay that, as a result of any amendment to, or change (including any announced
prospective change) in, the laws (or any regulations thereunder) of the United
States or any political subdivision thereof or therein, or as a result of any
official or administrative pronouncement or action or judicial decision
interpreting or applying such laws or regulations, which amendment or change
is effective or such prospective change, pronouncement or decision is
announced on or after the date of issuance of the Trust Preferred Securities
under the Trust Agreement, there is more than an insubstantial risk of
impairment of Greater Bay's ability to treat the Trust Preferred Securities
(or any substantial portion thereof) as "Tier 1 Capital" (or the then
equivalent thereof) for purposes of the capital adequacy guidelines of the
Federal Reserve, as then in effect and applicable to Greater Bay.
 
POSSIBLE TAX LAW CHANGES AFFECTING THE TRUST PREFERRED SECURITIES
 
  Recently the Clinton Administration announced its budget proposals for the
fiscal year 1998. That announcement included a proposal that could affect the
tax characteristics of the Junior Subordinated Debentures. Under the
Administration's proposal, no deduction would be allowed for interest or
original issue discount on an instrument issued by a corporation that has a
maximum term of more than 40 years, or is payable in stock of the issuer or a
related party. The budget announcement also states that no such deduction
would be allowed for certain indebtedness that is reflected as equity on the
issuer's balance sheet. The budget announcement states that the effective date
of the first proposal is for instruments issued "after the date of first
committee action," which is not a legally precise term. The budget
announcement is less clear about the proposed effective date of the second
proposal mentioned above.
 
  Similar proposals were made by the Administration last year. The Revenue
Reconciliation Bill of 1996 (the "1996 Bill") would, among other things, have
denied interest deductions for interest on an instrument, issued by a
corporation, that had a maximum term of more than 20 years and that was not
shown as indebtedness on the separate balance sheet of the issuer or, where
the instrument was issued to a related party (other than a corporation), where
the holder or some other related party issued a related instrument that is not
shown as indebtedness on the issuer's consolidated balance sheet. The 1996
Bill was never enacted, but it is likely that the second proposal in the
budget announcement mentioned above will be similar in some respects to the
proposal in the 1996 Bill. Enactment of this proposal could affect deduction
of interest expenses and original issue discount with respect to the Junior
Subordinated Debentures. This, in turn, could create a Tax Event affecting the
Trust Preferred Securities.
 
  In connection with the 1996 Bill, the Chairmen of the Senate Finance and
House Ways and Means Committees issued a joint statement that it was their
intention that the effective date of the Administration's legislative
proposals, if adopted, would be no earlier than the date of appropriate
Congressional action. Senate
 
                                      13
<PAGE>
 
Finance Committee Chairman William Roth has been quoted in the news media
recently as stating that the 1997 tax changes generally should be effective on
a prospective basis.
 
  It is intended that the Trust Preferred Securities and the Junior
Subordinated Debentures will be issued prior to any type of Congressional
committee action with respect to the aforementioned budget proposal. However,
due to business considerations, the unpredictability of when Congress will
begin action with respect to the Administration's proposals, and the
imprecision in the public statements concerning the anticipated effective date
of the legislative proposals, there can be no guarantee that these instruments
will not be affected by the aforementioned legislative proposals, if they are
enacted.
 
  There also can be no assurance that other future legislative proposals or
final legislation will not affect the ability of the Company to deduct
interest on the Junior Subordinated Debentures. Such a change could give rise
to a Tax Event, which may permit Greater Bay, upon approval of the Federal
Reserve, if then required under applicable capital guidelines or policies of
the Federal Reserve, to cause a redemption of the Trust Preferred Securities.
See "Description of the Trust Preferred Securities--Redemption--Tax Event
Redemption" and "Description of Junior Subordinated Debentures--Redemption."
See also "Certain Federal Income Tax Consequences--Possible Tax Law Changes
Affecting the Trust Preferred Securities."
 
POSSIBLE DISTRIBUTION OF JUNIOR SUBORDINATED DEBENTURES TO HOLDERS OF TRUST
PREFERRED SECURITIES
 
  Greater Bay will have the right at any time to terminate GBB Capital and,
after satisfaction of liabilities to creditors of GBB Capital as required by
applicable law, cause the Junior Subordinated Debentures to be distributed to
the holders of the Trust Preferred Securities in liquidation of GBB Capital.
The exercise of such right is subject to Greater Bay having received prior
approval of the Federal Reserve if then required under applicable capital
guidelines or policies of the Federal Reserve. Because holders of the Trust
Preferred Securities may receive Junior Subordinated Debentures in liquidation
of GBB Capital and because Distributions are otherwise limited to payments on
the Junior Subordinated Debentures, prospective purchasers of the Trust
Preferred Securities are also making an investment decision with regard to the
Junior Subordinated Debentures and should carefully review all the information
regarding the Junior Subordinated Debentures contained herein. See
"Description of the Trust Preferred Securities--Liquidation Distribution Upon
Termination" and "Description of Junior Subordinated Debentures."
 
  Under current United States federal income tax law and interpretations and
assuming, as expected, GBB Capital is classified as a grantor trust for such
purposes, a distribution of the Junior Subordinated Debentures upon a
liquidation of GBB Capital should not be a taxable event to holders of the
Trust Preferred Securities. However, if a Tax Event were to occur which would
cause GBB Capital to be subject to United States federal income tax with
respect to income received or accrued on the Junior Subordinated Debentures, a
distribution of the Junior Subordinated Debentures by GBB Capital could be a
taxable event to GBB Capital and the holders of the Trust Preferred
Securities. See "Certain Federal Income Tax Consequences--Distribution of
Junior Subordinated Debentures to Holders of Trust Preferred Securities."
 
SHORTENING OF STATED MATURITY OF JUNIOR SUBORDINATED DEBENTURES
 
  Greater Bay will have the right at any time to shorten the maturity of the
Junior Subordinated Debentures to a date not earlier than five years from the
date of issuance and thereby cause the Trust Preferred Securities to be
redeemed on such earlier date. The exercise of such right is subject to
Greater Bay having received prior approval of the Federal Reserve if then
required under applicable capital guidelines or policies of the Federal
Reserve. See "Description of Junior Subordinated Debentures--Redemption."
 
LIMITATIONS ON DIRECT ACTIONS AGAINST GREATER BAY AND ON RIGHTS UNDER THE
GUARANTEE
 
  The Guarantee guarantees to the holders of the Trust Preferred Securities
the following payments, to the extent not paid by GBB Capital: (i) any
accumulated and unpaid Distributions required to be paid on the Trust
 
                                      14
<PAGE>
 
Preferred Securities, to the extent that GBB Capital has funds on hand
available therefor at such time, (ii) the redemption price with respect to any
Trust Preferred Securities called for redemption, to the extent that GBB
Capital has funds on hand available therefor at such time, and (iii) upon a
voluntary or involuntary dissolution, winding-up or liquidation of GBB Capital
(unless the Junior Subordinated Debentures are distributed to holders of the
Trust Preferred Securities), the lesser of (a) the aggregate of the
Liquidation Amount and all accumulated and unpaid Distributions to the date of
payment to the extent that GBB Capital has funds on hand available therefor at
such time (the "Liquidation Distribution") and (b) the amount of assets of GBB
Capital remaining available for distribution to holders of the Trust Preferred
Securities after satisfaction of liabilities to creditors of GBB Capital as
required by applicable law. The holders of not less than a majority in
aggregate liquidation amount of the Trust Preferred Securities have the right
to direct the time, method and place of conducting any proceeding for any
remedy available to the Guarantee Trustee in respect of the Guarantee or to
direct the exercise of any trust power conferred upon the Guarantee Trustee
under the Guarantee Agreement. Any holder of the Trust Preferred Securities
may institute a legal proceeding directly against Greater Bay to enforce its
rights under the Guarantee without first instituting a legal proceeding
against GBB Capital, the Guarantee Trustee or any other person or entity. If
Greater Bay were to default on its obligation to pay amounts payable under the
Junior Subordinated Debentures, GBB Capital would lack funds for the payment
of Distributions or amounts payable on redemption of the Trust Preferred
Securities or otherwise, and, in such event, holders of the Trust Preferred
Securities would not be able to rely upon the Guarantee for payment of such
amounts. Instead, in the event a Debenture Event of Default shall have
occurred and be continuing and such event is attributable to the failure of
Greater Bay to pay interest on or principal of the Junior Subordinated
Debentures on the payment date on which such payment is due and payable, then
a holder of Trust Preferred Securities may institute a legal proceeding
directly against Greater Bay for enforcement of payment to such holder of the
principal of or interest on such Junior Subordinated Debentures having a
principal amount equal to the aggregate Liquidation Amount of the Trust
Preferred Securities of such holder (a "Direct Action"). In connection with
such Direct Action, Greater Bay will have a right of set-off under the
Indenture to the extent of any payment made by Greater Bay to such holder of
Trust Preferred Securities in the Direct Action. Except as described herein,
holders of Trust Preferred Securities will not be able to exercise directly
any other remedy available to the holders of the Junior Subordinated
Debentures or assert directly any other rights in respect of the Junior
Subordinated Debentures. See "Description of Junior Subordinated Debentures--
Enforcement of Certain Rights by Holders of Trust Preferred Securities" and
"Description of Guarantee." The Trust Agreement provides that each holder of
Trust Preferred Securities by acceptance thereof agrees to the provisions of
the Guarantee Agreement and the Indenture.
 
UNCERTAINTY OF DEDUCTIBILITY OF INTEREST ON THE JUNIOR SUBORDINATED DEBENTURES
 
  The Company's ability to deduct the interest paid on the Junior Subordinated
Debentures depends upon whether the Junior Subordinated Debentures are
characterized as debt instruments for federal income tax purposes, taking all
the relevant facts and circumstances into account. The Company believes that
the Junior Subordinated Debentures are debt instruments for federal income tax
purposes and that interest on the Junior Subordinated Debentures will,
therefore, be deductible by the Company. There is no clear authority on the
appropriate characterization for federal income tax purposes of instruments
such as the Junior Subordinated Debentures when they are issued in connection
with an offering of securities such as the Trust Preferred Securities. If the
interest on the Junior Subordinated Debentures is not deductible by the
Company, the Company would have significant additional income tax liabilities.
Any such tax liability could adversely affect the ability of Greater Bay to
pay interest on the Junior Subordinated Debentures to GBB Capital (and
consequently GBB Capital's ability to pay Distributions on the Trust Preferred
Securities and Greater Bay's ability to pay its obligations under the
Guarantee).
 
LIMITED COVENANTS
 
  The covenants in the Indenture are limited, and there are no covenants
relating to Greater Bay in the Trust Agreement. As a result, neither the
Indenture nor the Trust Agreement protects holders of Junior Subordinated
 
                                      15
<PAGE>
 
Debentures, or Trust Preferred Securities, respectively, in the event of a
material adverse change in Greater Bay's or the Company's financial condition
or results of operations or limits the ability of Greater Bay or any subsidiary
to incur additional indebtedness. Therefore, the provisions of these governing
instruments should not be considered a significant factor in evaluating whether
Greater Bay will be able to comply with its obligations under the Junior
Subordinated Debentures or the Guarantee.
 
LIMITED VOTING RIGHTS
 
  Holders of Trust Preferred Securities will generally have limited voting
rights relating only to the modification of the Trust Preferred Securities, the
dissolution, winding-up or liquidation of GBB Capital, and the exercise of GBB
Capital's rights as holder of Junior Subordinated Debentures. Holders of Trust
Preferred Securities will not be entitled to vote to appoint, remove or replace
the Property Trustee or the Delaware Trustee, and such voting rights are vested
exclusively in the holder of the Common Securities except upon the occurrence
of certain events described herein. In no event will the holders of the Trust
Preferred Securities have the right to vote to appoint, remove or replace the
Administrative Trustees; such voting rights are vested exclusively in the
holder of the Common Securities. The Property Trustee, the Administrative
Trustees and Greater Bay may amend the Trust Agreement without the consent of
holders of Trust Preferred Securities to ensure that GBB Capital will be
classified for United States federal income tax purposes as a grantor trust or
to ensure that GBB Capital will not be required to register as an "investment
company," even if such action adversely affects the interests of such holders.
See "Description of Trust Preferred Securities--Voting Rights; Amendment of the
Trust Agreement" and "--Removal of Trustees."
 
ABSENCE OF EXISTING PUBLIC MARKET; MARKET PRICES
 
  There is no existing market for the Trust Preferred Securities. Application
has been made to list the Trust Preferred Securities on the Nasdaq National
Market. There can be no assurance that an active and liquid trading market for
the Trust Preferred Securities will develop or that a continued listing of the
Trust Preferred Securities will be available on Nasdaq. Although the
Underwriter has informed GBB Capital and the Company that the Underwriter
intends to make a market in the Trust Preferred Securities offered hereby, the
Underwriter is not obligated to do so and any such market making activity may
be terminated at any time without notice to the holders of the Trust Preferred
Securities. Future trading prices of the Trust Preferred Securities will depend
on many factors including, among other things, prevailing interest rates, the
operating results and financial condition of the Company, and the market for
similar securities. As a result of the existence of Greater Bay's right to
defer interest payments on or, subject to prior approval of the Federal Reserve
if then required under applicable capital guidelines or policies of the Federal
Reserve, shorten the Stated Maturity of the Junior Subordinated Debentures, the
market price of the Trust Preferred Securities may be more volatile than the
market prices of debt securities that are not subject to such optional
deferrals or reduction in maturity. There can be no assurance as to the market
prices for the Trust Preferred Securities or the Junior Subordinated Debentures
that may be distributed in exchange for the Trust Preferred Securities if
Greater Bay exercises its right to terminate GBB Capital. Accordingly, the
Trust Preferred Securities that an investor may purchase, or the Junior
Subordinated Debentures that a holder of the Trust Preferred Securities may
receive in liquidation of GBB Capital, may trade at a discount from the price
that the investor paid to purchase the Trust Preferred Securities offered
hereby.
 
ABILITY OF THE COMPANY TO EXECUTE ITS BUSINESS STRATEGY
 
  The financial performance of the Company will depend in part, on the
Company's ability to successfully integrate the operations and management of
Mid-Peninsula and Cupertino and to implement its Super Community Banking
Philosophy. The Merger was effected in late November, 1996, and integration of
such operations and management are in the early stages. There can be no
assurance that the Company will be able to effectively and profitably integrate
the operations and management of Mid-Peninsula and Cupertino, or that it will
be able to profitably implement its Super Community Banking Philosophy. See
"Business--Super Community Banking Philosophy."

INTEREST RATE RISK
 
  Banking companies' earnings depend largely on the relationship between the
cost of funds, primarily deposits, and the yield on earning assets. This
relationship, known as the interest rate spread, is subject to fluctuation and
is affected by economic and competitive factors which influence interest
rates, the volume and mix of interest-earning assets and interest-bearing
liabilities, and the level of non-performing assets. Fluctuations in interest
rates affect the demand of customers for the Company's products and services.
The Company is subject to interest rate risk to the degree that its interest-
bearing liabilities reprice or mature more slowly or more rapidly or on a
different basis than its interest-earning assets. Given the Company's current
volume and mix of interest-bearing liabilities and interest-earning assets,
the Company's interest rate spread could be expected to increase during times
of rising interest rates and, conversely, to decline during times of falling
interest rates. Although the Company believes its current level of interest
rate sensitivity is reasonable, significant fluctuations in interest rates may
have an adverse effect on the Company's results of operations.
 
ECONOMIC CONDITIONS AND GEOGRAPHIC CONCENTRATION
 
  The Company's operations are located in Northern California and concentrated
primarily in Santa Clara and San Mateo Counties, which include the area known
as the "Silicon Valley." As a result of the geographic concentration, the
Company's results depend largely upon economic conditions in these areas. A
deterioration in economic conditions in the Company's market areas,
particularly in the technology and real estate industries on which these areas
depend, could have a material adverse impact on the quality of the Company's
loan portfolio and the demand for its products and services, and accordingly,
its results of operations. See "Business--Market Area."
 
GOVERNMENT REGULATION AND MONETARY POLICY
 
  The banking industry is subject to extensive federal and state supervision
and regulation. Such regulation limits the manner in which Greater Bay and the
Banks conduct their respective businesses, undertake new investments and
activities and obtain financing. This regulation is designed primarily for the
protection of the deposit insurance funds and consumers, and not to benefit
holders of the Company's securities. Financial institution regulation has been
the subject of significant legislation in recent years, and may be the subject
of further significant legislation in the future, none of which is in the
control of the Company. Significant new laws or changes in, or repeals of,
existing laws may cause the Company's results to differ materially. Further,
federal monetary policy, particularly as implemented through the Federal
Reserve System, significantly affects credit conditions for the Company,
primarily through open market operations in United States government
securities, the discount rate for bank borrowings and bank reserve
requirements, and a material change in these conditions would be likely to
have a material impact on the Company's results of operations. See
"Supervision and Regulation."
 
COMPETITION
 
  The banking and financial services business in California generally, and in
the Banks' market areas specifically, is highly competitive. The increasingly
competitive environment is a result primarily of changes in regulation,
changes in technology and product delivery systems, and the accelerating pace
of consolidation among financial services providers. The Banks compete for
loans, deposits and customers for financial services with other commercial
banks, savings and loan associations, securities and brokerage companies,
mortgage companies, insurance companies, finance companies, money market
funds, credit unions, and other nonbank financial service providers. Many of
these competitors are much larger in total assets and capitalization, have
greater access to capital markets and offer a broader array of financial
services than the Banks. There can be no assurance that the Banks will be able
to compete effectively in their markets and the results of operations of the
Company could be adversely affected if circumstances affecting the nature or
level of competition change. See "Business--Competition."

DEPENDENCE ON KEY PERSONNEL
 
  The Company's success depends substantially on certain members of its senior
management, in particular David L. Kalkbrenner, President and Chief Executive
Officer of Greater Bay and MPB, C. Donald Allen, President and Chief Executive
Officer of CNB, Steven C. Smith, Executive Vice President, Chief Operating
Officer and Chief Financial Officer of Greater Bay and Executive Vice President
and Chief Operating Officer of CNB, David R. Hood, Executive Vice President and
Senior Lending Officer of Greater Bay, Murray B. Dey, Executive Vice President
and Chief Credit Officer of MPB, and Hall Palmer, Executive Vice President and
Senior Trust Officer of Greater Bay. The Company's business and financial
condition could be materially adversely affected by the loss of the services of
any such individuals. The Company does not maintain key man life insurance. See
"Management--Board of Directors and Executive Officers."
 
CREDIT QUALITY
 
  A significant source of risk for the Company arises from the possibility that
losses will be sustained because borrowers, guarantors and related parties may
fail to perform in accordance with the terms of their loans. The Company has
adopted underwriting and credit monitoring procedures and credit policies,
including the establishment and review of the allowance for credit losses, that
management believes are appropriate to minimize this risk by assessing the
likelihood of nonperformance, tracking loan performance and diversifying the
Company's credit portfolio. Such policies and procedures, however, may not
prevent unexpected losses that could materially adversely affect the Company's
results of operations.
 
FORWARD-LOOKING STATEMENTS
 
  Certain statements contained in this Prospectus, including, without
limitation, statements containing the words "believes," "anticipates,"
"intends," "expects" and words of similar import, constitute "forward-looking
statements" within the meaning of the Reform Act. Such forward-looking
statements involve known and unknown risks, uncertainties and other factors
that may cause the actual results, performance or achievements of the Company
to be materially different from any future results, performance or achievements
expressed or implied by such forward-looking statements. Such factors include,
among others, the following: general economics and business conditions in those
areas in which the Company operates; demographic changes; competition;
fluctuations in interest rates; changes in business strategy or development
plans; changes in governmental regulation; credit quality; the availability of
capital to fund the expansion of the Company's business; and other factors
referenced in this Prospectus, including, without limitation, under the
captions "Prospectus Summary," "Risk Factors," "Management's Discussion and
Analysis of Financial Condition and Results of Operations," "Business" and
"Supervision and Regulation." Given these uncertainties, prospective investors
are cautioned not to place undue reliance on such forward-looking statements.
The Company disclaims any obligation to update any such factors or to publicly
announce the results of any revisions to any of the forward-looking statements
contained herein to reflect future events or developments.

                                USE OF PROCEEDS
 
  All of the proceeds from the sale of Trust Preferred Securities will be
invested by GBB Capital in the Junior Subordinated Debentures. The net
proceeds to Greater Bay from the sale of the Junior Subordinated Debentures
are estimated to be $        (net of estimated underwriting commission and
other estimated offering expenses). Greater Bay intends to invest
approximately $10.0 million of the net proceeds in the Banks to increase their
capital levels to support future growth. Greater Bay intends to use the
remaining net proceeds for general corporate purposes, which may include,
without limitation, funding additional investments in, or extensions of credit
to, the Banks and possible future acquisitions. The Company is not currently
engaged in negotiations with respect to any acquisitions. Pending their
application, the net proceeds may be invested in short-term investment grade
financial securities.
 
  Greater Bay is required by the Federal Reserve to maintain certain levels of
capital for bank regulatory purposes. On October 21, 1996, the Federal Reserve
announced that certain qualifying amounts of cumulative preferred securities
having the characteristics of the Trust Preferred Securities could be included
as Tier 1 capital for bank holding companies. Such Tier 1 capital treatment,
together with the Company's ability to deduct, for federal income tax
purposes, interest payable on the Junior Subordinated Debentures, will provide
Greater Bay with a cost-effective means of obtaining capital for bank
regulatory purposes.
 
                             ACCOUNTING TREATMENT
 
  For financial reporting purposes, GBB Capital will be treated as a
subsidiary of Greater Bay and, accordingly, the accounts of GBB Capital will
be included in the consolidated financial statements of the Company. The Trust
Preferred Securities will be presented as a separate line item in the
consolidated balance sheet of the Company under the caption "Company Obligated
Mandatorily Redeemable Preferred Securities of Subsidiary Trust Holding Solely
Junior Subordinated Debentures," and appropriate disclosures about the Trust
Preferred Securities, the Guarantee and the Junior Subordinated Debentures
will be included in the notes to consolidated financial statements. For
financial reporting purposes, the Company will record Distributions payable on
the Trust Preferred Securities as an expense in the consolidated statements of
operations.
 
  Future reports of Greater Bay filed under the Securities Exchange Act of
1934, as amended ("the Exchange Act"), will include a footnote to the
financial statements stating that (i) GBB Capital is wholly-owned, (ii) the
sole assets of GBB Capital are the Junior Subordinated Debentures (specifying
the principal amount, interest rate and maturity date of such Junior
Subordinated Debentures), and (iii) the back-up obligations, in the aggregate,
constitute a full and unconditional guarantee by Greater Bay of the
obligations of GBB Capital under the Trust Preferred Securities. GBB Capital
will not provide separate reports under the Exchange Act.

(1) The subsidiary trust is GBB Capital, which will hold the Junior
    Subordinated Debentures as its sole asset. The Trust Preferred Securities
    are issued by GBB Capital. The sole assets of GBB Capital consist of the
    Junior Subordinated Debentures issued by Greater Bay to GBB Capital. The

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
  Greater Bay Bancorp ("Greater Bay," on a parent-only basis, and the
"Company," on a consolidated basis) was formed as the result of the Merger
between Cupertino, the holding company for CNB, and Mid-Peninsula, the holding
company for MPB. The Merger, which has been accounted for as a pooling of
interests, was consummated in late November 1996. All of the financial
information for the Company for the periods prior to the Merger have been
restated to reflect the pooling of interests as if it occurred at the
beginning of the earliest reporting period presented.
 
  The following discussion and analysis is intended to provide greater details
of the results of operations and financial condition of the Company. The
following discussion should be read in conjunction with the information under
"Selected Consolidated Financial Data" and the Company's consolidated
financial statements and notes thereto and other financial data included
elsewhere in this Prospectus. Certain statements under this caption constitute
"forward-looking statements" under the Reform Act which involve risks and
uncertainties. The Company's actual results may differ significantly from the
results discussed in such forward-looking statements. Factors that might cause
such a difference include but are not limited to economic conditions,
competition in the geographic and business areas in which the Company conducts
its operations, fluctuations in interest rates, credit quality and government
regulation. For additional information concerning these and other factors, see
"Risk Factors."
 
RESULTS OF OPERATIONS
 
  The Company reported net income of $3.5 million in 1996, a 15% increase over
1995 net income of $3.0 million. The net income in 1995 was an 18.3% increase
over 1994 net income of $2.6 million. Net income per share was $1.04 in 1996,
compared with $0.96 in 1995 and $0.85 in 1994. The return on average assets
and return on average shareholders' equity were 0.65% and 8.12% in 1996,
compared with 0.70% and 7.98% in 1995 and 0.68% and 7.31% in 1994,
respectively.
 
  The increase in 1996 net income was the result of significant loan and
deposit growth, which resulted in increased net interest income, and increases
in trust fees, depositors' service fees and other fee income. Operating
expense increases required to service and support the Company's growth
partially offset the increase in revenues. The 1996 operating results included
$2.8 million ($2.0 million net of tax) in merger and other related charges.
Excluding these charges, the Company's net income, net income per share,
return on average assets and return on average shareholders' equity would have
been $5.5 million, $1.63, 1.02% and 12.86%, respectively.
 
  The increase in net income in 1995 over 1994 was due primarily to increased
growth in interest-earning assets, which was partially offset by the growth in
operating expenses. The operating results in 1995 included $2.1 million ($1.3
million net of taxes) in charges related to the settlement of litigation, the
closing of CNB's mortgage banking business unit and expenses related to
terminated merger discussions. Excluding these charges, the Company's net
income, net income per share, return on average assets and return on average
shareholders' equity would have been $4.3 million, $1.37, 1.00% and 11.39%,
respectively.
 
  NET INTEREST INCOME
 
  Net interest income increased 23.8% to $29.2 million in 1996 from $23.6
million in 1995 primarily due to the $95.5 million, or 23.4%, increase in
average interest-earning assets coupled with an 8 basis point increase in the
Company's interest rate spread. Net interest income increased 21.2% in 1995
from $19.5 million in 1994 primarily due to the combined effects of the $58.0
million, or 16.8%, increase in average interest-earning assets and the 2 basis
point increase in the Company's interest rate spread.

  The most significant impact on the Company's net interest income between
periods is derived from the interaction of changes in the volume of and rates
earned or paid on interest-earning assets and interest-bearing liabilities.
The volume of earning dollars in loans and investments, compared to the volume
of interest-bearing liabilities represented by deposits and borrowings,
combined with the spread, produces the changes in the net interest income
between periods. The table below sets forth, for the periods indicated, a
summary of the changes in interest income and interest expense resulting from
changes in average asset and liability balances (volume) and changes in
average interest rates (rate). The change in interest attributable to
simultaneous volume and rate changes have been reflected as volume variances.
Non-accrual loans are included in average loans.

- --------
(1) Interest income includes $356,000, $234,000 and $163,000 for 1996, 1995
    and 1994, respectively, to adjust to a fully taxable equivalent basis
    using the federal statutory rate of 34%.
 
  Interest income in 1996 increased 21.2% to $45.4 million from $37.5 million
in 1995. This was primarily due to the significant increase in loans, the
Company's highest yielding asset. Loan volume increases were the result of an
improving economy in the Company's market areas, as well as the addition of
experienced relationship managers and greater business development efforts by
the Company's relationship managers. This increase was partially offset by a
decline in the yield earned on average interest-earning assets. While average
interest-earning assets increased $94.5, or 23.4% to $498.8 million in 1996,
compared to $404.3 million in 1995, average loans increased $90.0 million, or
34.5%, to $350.7 million, or 70.3% of average interest-earning assets, in 1996
from $260.6 million, or 64.4% of average interest-earning assets, in 1995.
Conversely, other interest-earning assets, consisting of investment
securities, federal funds sold and other short-term investments, increased
only 3.1% to $148.1 million, or 29.7% of average interest-earning assets, in
1996 from $143.7 million, or 35.6% of average interest-earning assets, in
1995.
 
  The average yield on interest-earning assets declined 17 basis points to
9.10% in 1996 from 9.27% in 1995 primarily due to the decline in yields on
loans. Average yields on loans declined 55 basis points to 10.35% in 1996 from
10.90% in 1995 primarily due to competition. The average yield on other
interest-earning assets declined 16 basis points to 6.15% in 1996, compared to
6.31% in 1995.
 
  Interest expense in 1996 increased 16.7% to $16.2 million from $13.9 million
in 1995. This increase was due to greater volumes of interest-bearing
liabilities which was partially offset by lower interest rates paid on
interest-bearing liabilities. Average interest-bearing liabilities increased
23.8% to $392.4 million in 1996 from
 
                                      24
<PAGE>
 
$316.9 million in 1995 due to the efforts of the Banks' relationship managers
and deposits derived from the activities of the Greater Bay Trust Company and
the Venture Lending Group. During 1996, the average rate paid on interest-
bearing liabilities declined 25 basis points to 4.13% from 4.38% in 1995 due
to the repricing of deposit accounts.
 
  During 1996, average non-interest bearing deposits increased to $102.7
million from $77.7 million in 1995. As a result of such increase, non-interest
bearing deposits comprised 25.2% of total deposits at year end 1996, compared
to 22.2% at year end 1995.
 
  As a result of the foregoing, the Company's interest rate spread increased
to 4.97% in 1996 from 4.89% in 1995 and the net yield on interest-earning
assets increased slightly in 1996 to 5.85% from 5.83% in 1995.
 
  Interest income increased 34.0% to $37.7 million in 1995 from $28.0 million
in 1994, as a result of the combined effects of increases in average interest-
earning assets and the yields earned on such assets. Average interest-earning
assets increased 16.8% to $404.3 million in 1995 from $346.3 million in 1994
as a result of almost equivalent increases in both loans and other interest-
earning assets. The average yield on the higher volume of average interest-
earning assets increased 119 basis points to 9.27% in 1995 from 8.08% in 1994,
primarily as a result of increases in market rates of interest.
 
  Interest expense in 1995 increased 63.2% to $13.9 million from $8.5 million
in 1994, primarily as a result of the combined effect of increases in rates
paid on interest-bearing liabilities and the volume of interest-bearing
liabilities. As a result of increases in market rates of interest, the average
rate paid on average interest-bearing liabilities increased 117 basis points
to 4.38% in 1995 from 3.21% in 1994. Corresponding to the growth in average
interest-earning assets, average interest-bearing liabilities increased 19.7%
to $316.9 million in 1995 from $264.8 million in 1994.
 
  As a result of the foregoing, the Company's interest rate spread increased
to 4.89% in 1995 from 4.87% in 1994 and the net yield on interest-earning
assets increased to 5.83% in 1995 from 5.62% in 1994.
 
  The Company has noninterest-bearing liabilities on which it pays for certain
client service expenses. These expenses include messenger services, check
supplies and other related items and are included in operating expenses. If
these costs had been included in interest expense, the impact of these
expenses on the Company's net yield on interest-earning assets would have been
as follows for each of the years presented.

  The impact on the net yield on interest-earning assets is caused by off-
setting net interest income by the cost of client services expenses, which
reduces the yield on interest-earning assets. The cost for client services
expense is trending down and reflects the Company's efforts to manage its
client services expense.

  PROVISION FOR LOAN LOSSES
 
  The provision for loan losses creates an allowance for future loan losses.
The loan loss provision for each year is dependent on many factors, including
loan growth, net charge-offs, changes in the composition of the loan
portfolio, delinquencies, management's assessment of the quality of the loan
portfolio, the value of the underlying collateral on problem loans and the
general economic conditions in the Company's market area. The Company performs
a monthly assessment of the risk inherent in its loan portfolio, as well as a
detailed review of each asset determined to have identified weaknesses. Based
on this analysis, which includes reviewing historical loss trends, current
economic conditions, industry concentrations and specific reviews of assets
classified with identified weaknesses, the Company makes provisions for
potential loan losses. Specific allocations are made for loans where the
probability of a loss can be defined and reasonably determined, while the
balance of the provisions for loan losses are based on historical data,
delinquency trends, economic conditions in the Company's market area and
industry averages. Annual fluctuation in the provision for loan losses result
from management's assessment of the adequacy of the allowance for loan losses,
and ultimate loan losses may vary from current estimates.
 
  The provision for loan losses in 1996 was $2.0 million, compared to $0.9
million in 1995 and $1.8 million in 1994. In addition, in connection with the
Merger, the Company made an $800,000 additional provision for loan losses to
conform the Banks' reserve allocation methodologies, which is included in
operating expenses. The increased provision for loan losses during 1996
reflects the $160.5 million increase in gross loans outstanding at December
31, 1996 from year-end 1995. Notwithstanding the substantial increase in loans
outstanding, non-performing loans, comprised of non-accrual loans and accruing
loans past due 90 days or more, declined to $3.1 million or 0.69% of loans
outstanding at December 31, 1996 from $3.3 million or 1.15% loans outstanding
at December 31, 1995. The $1.8 million provision for loan losses during 1994
reflected the higher level of non-performing loans experienced by the Company
during 1994. At December 31, 1994, non-performing loans were $5.0 million, or
2.07% of loans outstanding at such date.

allowance for loan losses, see "--Financial Condition--Non-Performing and
Classified Assets" herein.

</TABLE>
 
  The increase in other income in 1996 is primarily the result of a $716,000
increase in trust fees and a $374,000 increase in depositors' service fees.
The trust fee increase is due to significant growth in assets under management
in Greater Bay Trust Company. Trust assets increased to $418.0 million at
year-end 1996, compared to $270.0 million at December 31, 1995 and $157.0
million at December 31, 1994. Depositors' service fees increased due to growth
in deposits.
 
  The decrease in other income in 1995 from 1994 is due primarily to the
decline in the activities of the mortgage banking business unit. The unit
generated $137,000 in gains on the sale of mortgage loans in 1995, compared to
$993,000 in 1994. In early 1995, the Company closed the mortgage banking
business unit due to the sharp rise in interest rates during 1994 and the
impact the rising rates had on originations.
 
                                      26
<PAGE>
 
  The fluctuation in gain on sale of SBA loans is due primarily to the mix of
SBA loans originated for sale combined with the effect of market pricing on
loans sold. SBA loans with longer maturities command a higher premium than
loans with shorter maturity periods. In 1996 compared to 1995, the Company
originated and sold fewer long-term real estate loans and the pricing on loans
sold declined slightly. During 1995 compared to 1994, the Company generated
more long-term commercial real estate loans that were sold in the secondary
market, thus causing the increase in gain on sale of SBA loans. In addition,
lower market interest rates in 1994 provided higher premiums on SBA loan
sales.
 
  OPERATING EXPENSES
 
  Operating expenses totaled $23.9 million for 1996, compared to $19.7 million
for 1995 and $16.2 million for 1994. The ratio of operating expenses to
average assets was 4.43% in 1996, 4.53% in 1995, and 4.31% in 1994. Operating
expenses in 1996 and 1994 included $2.8 million and $608,000, respectively, in
merger and other related costs, while 1995 operating expenses included $2.2
million related to the settlement of litigation, the closing of CNB's mortgage
banking unit and expenses related to terminated merger discussions. Excluding
these costs, operating expenses to average assets would have been 3.92% in
1996, 4.04% in 1995 and 4.15% in 1994.
 
  The efficiency ratio is computed by dividing total operating expenses by net
interest income and other income. An increase in the efficiency ratio
indicates that more resources are being utilized to generate the same (or
greater) volume of income while a decrease would indicate a more efficient
allocation of resources. The Company's efficiency ratio for 1996 was 73.83%,
compared to 76.76% in 1995 and 71.87% in 1994. Excluding nonrecurring costs,
the Company's efficiency ratios were 65.21%, 68.43% and 69.18% in 1996, 1995
and 1994, respectively. The decline in the Company's efficiency ratio was due
to the investment in infrastructure in 1994 and early 1995 which allowed the
Company to grow its revenue base in 1995 and 1996 without significant
increases in operating expenses.
 
  The following table represents the major components of operating expenses
for the years indicated.

  Compensation and benefits expenses increased in 1996 to $11.8 million,
compared to $10.1 million in 1995 and $8.5 million in 1994, primarily due to
the addition of personnel at Greater Bay Trust Company and an increase in the
number of relationship managers at the Banks.
 
  The increase in occupancy and equipment expense in 1996 was primarily due to
the opening of CNB's new Emerson office and the Greater Bay Trust Company
office in downtown Palo Alto, California. The increase in occupancy and
equipment expense in 1995 was due to the installation of a larger data
processing system, which included a local and wide area network to connect all
of the CNB office locations.
 
  Expenses for professional services and legal costs, including consulting and
audit services, decreased to $1.3 million in 1996, compared to $3.0 million in
1995 and $1.2 million in 1994. The decrease in 1996 is primarily attributable
to a one-time charge of $1.8 million in 1995 for a legal settlement related to
trust department activities.
 
  Client services expenses increased to $411,000 in 1996, compared to $337,000
in 1995 and $376,000 in 1994 as a result of an increase in the volume of
noninterest-bearing demand deposits from commercial customers for which the
Company provides services. These expenses include messenger services, check
supplies and other related items. For information concerning the impact of
these expenses on net yield on interest-earning assets, see "--Net Interest
Income" herein.
 
  Federal Deposit Insurance Corporation ("FDIC") deposit insurance and Office
of the Comptroller of the Currency regulatory assessments decreased to
$102,000 in 1996, compared to $551,000 in 1995, and $858,000 in 1994. The
decline in FDIC insurance expense is a result of the lowering of deposit
insurance premiums by the FDIC when the Bank Insurance Fund ("BIF") was fully
funded as of March 1995.
 
  The increase in other operating expense in 1996 was related to the rapid
growth in the Company's loan and deposit portfolios and trust assets. The
principal expense increases were $570,000 in marketing expenses, $80,000 in
trust data processing charges and $236,000 in supplies and postage expenses.
The increase in 1995 over 1994 was also primarily in marketing, trust and
supplies and postage expenses.
 
  INCOME TAXES
 
  The Company's income tax rate for 1996 was 45.5%, compared to 39.4% in 1995
and 36.41% in 1994. The effective rate in 1996 was higher than the statutory
rate due to the impact of nondeductible merger expenses.
 
FINANCIAL CONDITION
 
  Total assets increased 30.2% to $622.0 million at December 31, 1996,
compared to $477.8 million at December 31, 1995. Total assets increased 19.0%
in 1995 from $401.6 million at December 31, 1994. The increases in 1996 and
1995 were primarily due to increases in the Company's loan portfolio funded by
growth in deposits.
 
  LOANS
 
  Total gross loans increased 55.3% to $450.8 million at December 31, 1996,
compared to $290.3 million at December 31, 1995. Total gross loans increased
19.5% in 1995 from $243.0 million at year-end 1994. The increases in loan
volumes in 1996 and 1995 were due to an improving economy in the Company's
market areas coupled with the business development efforts by the Company's
relationship managers.
 
  The Company's loan portfolio is concentrated in commercial (primarily
manufacturing, service and technology) and real estate lending, with the
balance in consumer loans. While no specific industry concentration is
considered significant, the Company's lending operations are located in the
Company's market areas that are dependent on the technology and real estate
industries and their supporting companies. Thus, the Company's borrowers could
be adversely impacted by a downturn in these sectors of the economy which
could reduce the demand for loans and adversely impact the borrowers'
abilities to repay their loans.

  NON-PERFORMING AND CLASSIFIED ASSETS
 
  Management generally places loans on non-accrual when they become 90 days
past due, unless they are well secured and in the process of collection. When
a loan is placed on non-accrual status, any interest previously accrued but
not collected is reversed from income. Loans are charged off when management
determines that collection has become unlikely. Restructured loans are those
where the Banks have granted a concession on the interest paid or original
repayment terms due to financial difficulties of the borrower. Other real
estate owned consists of real property acquired through foreclosure on the
related collateral underlying defaulted loans.

  At December 31, 1996, the Company had $1.9 million in non-accrual loans.
Non-accrual loans included 11 loans with aggregate principal balances ranging
from $3,000 to $962,000. Interest income foregone on non-performing loans
outstanding at year end totaled $215,000, $245,000 and $275,000 for the years
ended December 31, 1996, 1995 and 1994, respectively.
 
  The Company records other real estate at the lower of carrying value or fair
value less estimated costs to sell. Estimated losses that result from the
ongoing periodic valuation of these properties are charged to earnings with a
provision for losses on foreclosed property in the period in which they are
identified. At December 31, 1996, other real estate owned consisted of one
property acquired through foreclosure with a carrying value of $152,000.
 
  The policy of the Company is to review each loan in the portfolio to
identify problem credits. There are three classifications for problem loans:
"substandard," "doubtful" and "loss." Substandard loans have one or more
defined weaknesses and are characterized by the distinct possibility that the
Banks will sustain some loss if the deficiencies are not corrected. Doubtful
loans have the weaknesses of substandard loans with the additional
characteristic that the weaknesses make collection or liquidation in full on
the basis of currently existing facts, conditions and values questionable, and
there is a high possibility of loss. A loan classified loss is considered
uncollectible and its continuance as an asset is not warranted.
 
  The following table sets forth classified loans at the dates indicated.

  With the exception of these classified loans, management is not aware of any
loans as of December 31, 1996 where the known credit problems of the borrower
would cause management to have serious doubts as to the ability of such
borrowers to comply with their present loan repayment terms and which would
result in such loans being included in the non-performing asset table above at
some future date. Management cannot, however, predict the extent to which
economic conditions in the Company's market areas may worsen or the full
impact such an environment may have on the Company's loan portfolio.
Accordingly, there can be no assurance that other loans will not become 90
days or more past due, be placed on non-accrual or become restructured loans,
in substance foreclosures or other real estate owned in the future.

  ALLOWANCE FOR LOAN LOSSES
 
  The allowance for loan losses is established through a provision for loan
losses based on management's evaluation of risk inherent in its loan portfolio
and economic conditions in the Company's market areas. See "--Provision for
Loan Losses" herein. The allowance is increased by provisions charged against
earnings and reduced by net loan charge-offs. Loans are charged off when they
are deemed to be uncollectible; recoveries are generally recorded only when
cash payments are received.
 
  The following table sets forth information concerning the Company's
allowance for loan losses at the dates and for the years indicated.

  Management considers changes in the size and character of the loan
portfolio, changes in non-performing and past due loans, historical loan loss
experience, and the existing and prospective economic conditions when
determining the adequacy of the allowance for loan losses. Although management
believes that the allowance for loan losses is adequate to provide for both
potential losses and estimated inherent losses in the portfolio, future
provisions will be subject to continuing evaluations of the inherent risk in
the portfolio and if the economy declines or asset quality deteriorates,
additional provisions could be required.

  The following table provides a summary of the allocation of the allowance
for loan losses for specific loan categories at the dates indicated. The
allocations presented should not be interpreted as an indication that loans
charged to the allowance for loan losses will be incurred in these amounts or
proportions, or that the portion of the allowance allocated to each loan
category represents the total amount available for future losses that may
occur within these categories. The unallocated portion of the allowance for
loan losses and the total allowance is applicable to the entire loan
portfolio.

  INVESTMENT SECURITIES
 
  The Company's investment portfolio is managed to meet the Company's
liquidity needs through proceeds from scheduled maturities and is utilized for
pledging requirements for deposits of state and political subdivisions and
securities sold under repurchase agreements. The portfolio is comprised of
U.S. Treasury securities, U.S. government agency securities, mortgage-backed
securities, obligations of states and political subdivisions and a modest
amount of equity securities including Federal Reserve Bank stock and Federal
Home Loan Bank stock. Federal funds sold are additional investments which are
not classified as investment securities. Investment securities classified as
available-for-sale are recorded at fair market value, while investment
securities classified as held-to-maturity are recorded at cost. Unrealized
gains or losses, net of the deferred tax effect, are reported as increases or
decreases in shareholders' equity for available-for-sale securities.

(1) Mortgage-backed securities are shown at contractual maturity; however, the
    average life of these mortgage-backed securities may differ due to
    principal prepayments.
(2) Certain U.S. Agency fixed and variable rate note obligations may be
    called, without penalty, at the discretion of the issuer. This may cause
    the actual maturities to differ significantly from the contractual
    maturity dates.
(3) Mutual funds with no stated maturity total $2.0 million ($1.9 million
    market value).
(4) Yields on tax exempt securities have been computed on a fully tax-
    equivalent basis.

  DEPOSITS
 
  The Company emphasizes developing total client relationships with its
customers in order to increase its core deposit base. Deposits reached $559.3
million at December 31, 1996, an increase of 29.5% compared to deposits of
$431.8 million at December 31, 1995. In 1995, deposits increased 25.05% from
$345.3 million at December 31, 1994.
 
                                      34

  Total average interest-bearing deposits increased 21.0% to $384.2 million
for 1996, compared to an average of $303.6 million for 1995. In 1995, average
interest-bearing deposits increased 18.1% over average deposits of $257.0
million in 1994. The increase in deposits was due to the continued marketing
efforts directed at commercial business clients in the Company's market areas,
coupled with an increase in deposits related to the activities of the Greater
Bay Trust Company and the Venture Lending Group.
 
  Noninterest-bearing deposits were $139.9 million at December 31, 1996,
compared to $96.1 million at December 31, 1995 and $81.0 million at December
31, 1994. Average noninterest-bearing deposits in 1996 were $102.7 million,
compared to $77.7 million in 1995 and $75.2 million in 1994. As its regional
offices expand, the Company anticipates this funding source to increase.
 
  Money market and other interest-bearing demand accounts reached $419.3
million at year-end 1996, an increase of 24.9% from the prior year. Money
market and other interest-bearing demand deposits of $335.7 million at
December 31, 1995 were up 26.5% from $265.3 million at December 31, 1994.
 
  Time certificates of deposit of more than $100,000, savings and other time
deposits totaled $68.2 million, or 12.2% of total deposits, at December 31,
1996, compared to $63.8 million, or 14.8% of total deposits, at December 31,
1995 and $54.5 million, or 15.7%, of total deposits at December 31, 1994.

  As of December 31, 1996, the Company had $20.6 million in brokered deposits
outstanding.
 
  LIQUIDITY AND CASH FLOW
 
  The objective of liquidity management is to maintain each Bank's ability to
meet the day-to-day cash flow requirements of its clients who either wish to
withdraw funds or require funds to meet their credit needs. The Company must
manage its liquidity position to allow the Banks to meet the needs of their
clients, while maintaining an appropriate balance between assets and
liabilities to meet the return on investment requirements of its shareholders.
The Company monitors the sources and uses of funds on a daily basis to
maintain an acceptable liquidity position. In addition to liquidity from core
deposit growth and repayments and maturities of loans and investments, the
Banks utilize brokered deposit lines, sell securities under agreements to
repurchase and borrow overnight federal funds. In addition, during 1995 the
Company issued $3.0 million of subordinated notes.
 
  Greater Bay is a company separate and apart from the Banks. It must provide
for its own liquidity. Substantially all of Greater Bay's revenues are
obtained from interest received and dividends declared and paid by the Banks.
There are statutory and regulatory provisions that could limit the ability of
the Banks to pay dividends to Greater Bay. See "Supervision and Regulation."
At December 31, 1996, the Banks had approximately $6.3 million in the
aggregate available to be paid as dividends to Greater Bay. Management of
Greater Bay believes that such restrictions will not have an impact on the
ability of Greater Bay to meet its ongoing cash obligations, including those
relating to the Junior Subordinated Debentures. As of December 31, 1996, the
Company did not have any material commitments for capital expenditures.

  Net cash provided by operating activities primarily representing net
interest income, totaled $6.2 million for 1996, $10.2 million for 1995 and
$6.4 million for 1994. Cash used for investing activities totaled $150.3
million in 1996, $78.4 million in 1995 and $31.4 million in 1994. The funds
used for investing activities primarily represent increases in loans and
investments for each year reported.
 
  For the year ended December 31, 1996, net cash provided by financing
activities was $139.9 million. Historically, the primary financing activity of
the Company has been deposits and short-term borrowings. Deposits increased
$127.5 million for the year ended December 31, 1996 and short-term borrowings
increased $12.0 million for the same period. For the year ended December 31,
1995, net cash provided by financing activities was $71.4 million. Deposits
increased $85.5 million, while short-term borrowings decreased $17.3 million.
Net proceeds from subordinated notes issued in the third quarter of 1995
provided $3.0 million.
 
  CAPITAL RESOURCES
 
  Shareholders' equity at December 31, 1996 increased to $44.7 million from
$40.1 million at December 31, 1995 and from $36.0 million at December 31,
1994. During 1996, the Company paid aggregate cash dividends of $0.44 per
share.
 
  The Company has provided the majority of its capital requirements through
the retention of earnings. In the third quarter of 1995, the Company increased
its capital base by raising $3.0 million of subordinated notes which qualify
as Tier 2 capital. The private offering was subscribed by the Company's
directors, officers and other accredited investors.
 
  A banking organization's total qualifying capital includes two components,
core capital (Tier 1 capital) and supplementary capital (Tier 2 capital). Core
capital, which must comprise at least half of total capital, includes common
shareholders' equity, qualifying perpetual preferred stock, and minority
interests, less goodwill. Supplementary capital includes the allowance for
loan losses (subject to certain limitations), other perpetual preferred stock,
certain other capital instruments, and term subordinated debt. The Company's
major capital components are shareholders' equity in core capital, and the
allowance for loan losses and subordinated debt in supplementary capital.
 
  At December 31, 1996, the minimum risk-based capital requirements to be
considered adequately capitalized are 4.0% for core capital and 8.0% for total
capital. Federal banking regulators have also adopted leverage capital
guidelines to supplement risk-based measures. The leverage ratio is determined
by dividing Tier 1 capital as defined under the risk-based guidelines by
average total assets (not risk-adjusted) for the preceding quarter. The
minimum leverage ratio is 3.0%, although banking organizations are expected to
exceed that amount by 1.0%, 2.0% or more, depending on their circumstances.
 
  Pursuant to the Federal Deposit Insurance Corporation Improvement Act of
1991, the Federal Reserve, the Comptroller of the Currency and the FDIC have
adopted regulations, effective December 19, 1992, setting forth a five-tier
scheme for measuring the capital adequacy of the financial institutions they
supervise. The capital levels of the Company at December 31, 1996 and the two
highest levels recognized under these regulations are set forth below.

</TABLE>
 
  At December 31, 1996, the Company's risk-based capital ratios were 8.75% for
Tier 1 risk-based capital and 10.54% for total risk-based capital, compared to
11.38% and 13.43% as of December 31, 1995, respectively. The Company's
leverage ratio was 7.27% at December 31, 1996, compared to 8.69% at December
31, 1995. These ratios all exceeded the well-capitalized guidelines shown
above.

<PAGE>
 
  In addition, at December 31, 1996, each of the Banks had levels of capital
which exceeded the well-capitalized guidelines. However, in order for CNB to
remain well-capitalized during 1997, additional capital will be required. For
additional information on the capital levels and capital ratios of the Company
and each of the Banks, see Note 14 of Notes to the Consolidated Financial
Statements.
 
  The Company anticipates that the economic and business conditions in its
market areas will continue to expand in 1997, resulting in continued growth in
earning assets and deposits. With the proceeds from this offering, the Company
believes that it will have adequate capital to support anticipated growth
while allowing the Company to remain well-capitalized under applicable
regulations. However, should growth exceed expectations or in the event an
acquisition opportunity arises to expand market share, it may be necessary for
the Company to raise additional capital through the sale of either debt or
equity securities. It is anticipated that any such debt securities would
constitute Senior and Subordinated Debt.
 
  INTEREST RATE RISK MANAGEMENT
 
  Interest rate risk management is a function of the repricing characteristics
of the Company's portfolio of assets and liabilities. Interest rate risk
management focuses on the maturity structure of assets and liabilities and
their repricing characteristics during periods of changes in market interest
rates. Effective interest rate risk management seeks to ensure that both
assets and liabilities respond to changes in interest rates within an
acceptable time frame, thereby minimizing the effect of interest rate
movements on net interest income. Interest rate sensitivity is measured as the
difference between the volumes of assets and liabilities in the Company's
current portfolio that are subject to repricing at various time horizons: one
day or immediate, two days to six months, seven to twelve months, one to three
years, three to five years, over five years and on a cumulative basis. The
differences are known as interest sensitivity gaps. The following table shows
interest sensitivity gaps for different intervals as of December 31, 1996.

</TABLE>
 
  The foregoing table demonstrates that the Company had a negative cumulative
one year gap of $28.3 million, or 4.56% of total assets, at December 31, 1996.
In theory, this would indicate that at December 31, 1996, $28.3 million more
in liabilities than assets would reprice if there was a change in interest
rates over the
 
                                      37
<PAGE>
 
next 360 days. If interest rates were to increase, the negative gap would tend
to result in a lower net interest margin. However, changes in the mix of
earning assets or supporting liabilities can either increase or decrease the
net interest margin without affecting interest rate sensitivity. In addition,
the interest rate spread between an asset and its supporting liability can
vary significantly while the timing of repricing of both the asset and its
supporting liability can remain the same, thus impacting net interest income.
This characteristic is referred to as a basis risk and, generally, relates to
the repricing characteristics of short-term funding sources such as
certificates of deposit.
 
  The impact of fluctuations in interest rates on the Company's projected next
twelve month net interest income and net income has been evaluated through an
interest rate shock simulation modeling analysis that includes various
assumptions regarding the repricing relationship of assets and liabilities, as
well as the anticipated changes in loan and deposit volumes over differing
rate environments. As of December 31, 1996 the analysis indicates that the
Company's net interest income would increase a maximum of 8.0% if rates rose
200 basis points immediately and would decrease a maximum of 8.0% if rates
declined 200 basis points immediately. In addition, the results indicate that
notwithstanding the Company's negative gap position, which would indicate that
the net interest margin declines when rates rise, the Company's net interest
margin increases during rising rate periods due to the basis risk imbedded in
the Company's interest-bearing liabilities.
 
  Varying interest rate environments can create unexpected changes in
prepayment levels of assets and liabilities which are not reflected in the
interest sensitivity analysis table. These prepayments may have significant
effects on the Company's net interest margin. Because of these factors, an
interest sensitivity gap report may not provide a complete assessment of the
Company's exposure to changes in interest rates.
 
  RECENT ACCOUNTING PRONOUNCEMENTS
 
  In October 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for
Stock-Based Compensation." This statement establishes a new fair value based
accounting method for stock-based compensation plans and encourages (but does
not require) employers to adopt the new method in place of the provisions of
Accounting Principles Board Opinion No. 25 ("APB 25"), "Accounting for Stock
Issued to Employees." Under the fair value based method, compensation cost is
measured at the grant date based on the value of the award and is recognized
over the service period. Companies may continue to apply the accounting
provisions of APB 25 in determining net income; however, they must apply the
disclosure requirements of SFAS 123. The recognition provisions and disclosure
requirements of SFAS No. 123 were effective January 1, 1996. The Company has
not adopted the recognition provisions of SFAS No. 123 but has adopted the
disclosure requirements. For further information on SFAS No. 123, see Note 11
of the Notes to Consolidated Financial Statements.
 
  In June 1996, the FASB issued SFAS No. 125, "Accounting for Transfers and
Servicing of Financial Assets and Extinguishment of Liabilities." This
statement provides accounting and reporting standards for transfers and
servicing of financial assets and extinguishment of liabilities. This
statement provides consistent standards for distinguishing transfers of
financial assets that are sales from transfers that are secured borrowings. A
transfer of financial assets in which the transferor surrenders control over
those assets is accounted for as a sale to the extent that consideration other
than beneficial interests in the transferred assets is received in exchange.
This statement also requires that liabilities and derivatives incurred or
obtained by transferors as part of a transfer of financial assets be initially
measured at fair value, if practicable. It also requires that servicing assets
and other retained interests in the transferred assets be measured by
allocating the previous carrying amount between the assets sold, if any, and
retained interests, if any, based on their relative fair value at the date of
the transfer. Furthermore, this statement requires that debtors reclassify
financial assets pledged as collateral, and that secured parties recognize
those assets and their obligation to return them in certain circumstances in
which the secured party has taken control of those assets. In addition, the
statement requires that a liability be derecognized if and only if either (a)
the debtor pays the creditor and is relieved of its obligation for the
liability or (b) the debtor is legally released from being the primary obligor
under the liability either judicially or by the creditor. Accordingly, a
liability is not considered extinguished by an in-substance defeasance. SFAS
125 is effective for
 
                                      38
<PAGE>
 
transfers and servicing of financial assets and extinguishment of liabilities
occurring after December 31, 1996, and is to be applied prospectively.
Management does not believe that the application of this statement will have a
material impact on the Company's financial statements.
 
  In May 1995, the FASB issued SFAS No. 122, "Accounting for Mortgage
Servicing Rights." SFAS 122 amends certain provisions of SFAS No. 65,
"Accounting for Certain Mortgage Banking Activities," to require that a
mortgage banking enterprise recognize as separate assets rights to service
mortgage loans for others, however those servicing rights are acquired. A
mortgage banking enterprise that acquires mortgage servicing rights through
either the purchase or origination of mortgage loans and sells or securitizes
those loans with servicing rights retained should allocate the total cost of
the mortgage loans to the mortgage servicing rights and the loans (without the
mortgage servicing rights) based on their relative fair value, if it is
practicable to estimate those fair values. If it is not practicable to
estimate those fair values, the entire cost of the acquisition should be
allocated to the mortgage loans only. SFAS 122 is effective for years
occurring after December 31, 1995. Adoption of this pronouncement did not have
a material impact on the Company's financial statements.
 
  In March 1995, the FASB issued SFAS No. 121 "Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." This
statement establishes accounting standards for the impairment of long-lived
assets, certain identifiable intangibles, and goodwill related to those assets
to be held and used and for long-lived assets and certain identifiable
intangibles to be disposed of. An impairment loss is measured as the amount by
which the carrying amount of the asset exceeds the fair value of the asset.
After an impairment is recognized, the reduced carrying amount of the asset
shall be accounted for as its new cost. SFAS No. 121 is effective for years
occurring after December 31, 1995. Adoption of this pronouncement did not have
a material impact on the Company's financial statements.
 
CHANGE IN ACCOUNTANT
 
  Prior to the Merger, Cupertino's independent accountants were Coopers &
Lybrand, L.L.P. ("Coopers & Lybrand") and Mid-Peninsula's independent
accountants were KPMG Peat Marwick, LLP ("Peat Marwick"). On consummation of
the Merger, Mid-Peninsula changed its name to Greater Bay Bancorp, and on
December 17, 1996, Greater Bay changed its independent accountant by
terminating its engagement of Peat Marwick and selecting Coopers & Lybrand as
its independent accountant to audit its financial statements for the year
ended December 31, 1996. The decision to terminate Greater Bay's engagement of
Peat Marwick and select Coopers & Lybrand was unanimously recommended by
Greater Bay's Audit Committee and approved by Greater Bay's Board of
Directors. During the two most recent fiscal years of the Company and any
subsequent interim period preceding the aforesaid change, there were no
disagreements between the Company and Peat Marwick on any matter of accounting
principles or practices, financial statement disclosure or auditing scope or
procedure which if not resolved to the satisfaction of Peat Marwick would have
caused them to make reference to the subject matter of the disagreement in
their report. All descriptions contained herein of communications between the
Company and third parties and reports of third parties are qualified in their
entirety by the text of the communications and reports referred to herein.
 
  Peat Marwick's report on the financial statements for 1994 and 1995
contained no adverse opinion or disclaimer of opinion nor was it qualified or
modified as to uncertainty, audit scope, or accounting principles, except
their report dated January 22, 1996, relating to the consolidated balance
sheets of Mid-Peninsula Bancorp and subsidiary as of December 31, 1995 and
1994, and the related consolidated statements of operations, changes in
shareholders' equity, and cash flows for each of the years in the three-year
period ended December 31, 1995, referenced other auditors. On October 7, 1994,
the Company acquired San Mateo County Bancorp on a pooling-of-interests basis.
Peat Marwick did not audit the consolidated financial statements of San Mateo
County Bancorp as of and for the year ended December 31, 1993. These
statements, which were included in the 1993 restated consolidated financial
statements, were audited by other auditors, whose report contained an
explanatory paragraph regarding the adoption SFAS No. 109, "Accounting for
Income Taxes," and SFAS No. 115, "Accounting for Certain Investments, Debt and
Equity Securities." Peat Marwick's report, insofar as it relates to the
amounts included for San Mateo County Bancorp, is based solely on the report
of other auditors.

GREATER BAY
 
  Greater Bay is a bank holding company operating CNB and MPB with seven
regional offices in Cupertino, Palo Alto, San Mateo, San Carlos and San Jose,
California. At December 31, 1996, the Company had total assets of
$622.0 million, total net loans of $441.6 million and total deposits of $559.3
million.
 
HISTORY
 
  Greater Bay is the result of the Merger of Cupertino and Mid-Peninsula.
Cupertino was formed in 1984 as the holding company for CNB, a national
banking association which began operating in 1985. Mid-Peninsula was formed in
1984 under the name San Mateo County Bancorp ("San Mateo") as the bank holding
company of San Mateo County National Bank, which subsequently changed its name
to WestCal National Bank ("WestCal") in 1991. In 1994, WestCal was merged into
Mid-Peninsula Bank, a California state chartered bank organized in 1987, and
San Mateo concurrently changed its name to Mid-Peninsula Bancorp.
 
  Cupertino and Mid-Peninsula undertook the Merger with the intention of
achieving five primary goals. These goals included (i) developing a greater
banking presence throughout Santa Clara and San Mateo Counties by increasing
the number of banking offices to seven; (ii) reaching a critical mass in the
Company's market areas in order to better meet competitive challenges inherent
in the banking and financial services industries; (iii) enabling the resulting
Company to maximize the utilization of capital by increasing the float and
marketability of its common stock and, by virtue of its larger size, obtaining
access to a lower cost of capital; (iv) providing an opportunity to realize
operating efficiencies made available by the combination of Cupertino and Mid-
Peninsula; and (v) enabling CNB and MPB to cross-sell products.
 
SUPER COMMUNITY BANKING PHILOSOPHY
 
  In order to meet the demands of the increasingly competitive banking and
financial services industries, management has adopted a business philosophy
referred to as the "Super Community Banking Philosophy." The Super Community
Banking Philosophy is based on management's belief that banking customers
value doing business with locally managed institutions that can provide a full
service commercial banking relationship through an understanding of the
customer's financial needs and the flexibility to customize products and
services to meet those needs. Management further believes that banks are
better able to build successful customer relationships by affiliating with a
holding company that provides cost effective administrative support services
while promoting bank autonomy and flexibility.
 
  To implement this philosophy, Greater Bay operates CNB and MPB as separate
subsidiaries by retaining their independent names along with their individual
Boards of Directors. Both MPB and CNB have established strong reputations and
customer followings in their respective market areas through attention to
client service and an understanding of client needs. In an effort to
capitalize on the identities and reputations of the Banks, the Company will
continue to market its services under the CNB and MPB names, primarily through
each Bank's relationship managers. The primary focus for the Banks'
relationship managers is to cultivate and nurture their client relationships.
Relationship managers are assigned to each borrowing client to provide
continuity in the relationship. This emphasis on personalized relationships
requires that all of the relationship managers maintain close ties to the
communities in which they serve, so they are able to capitalize on their
efforts through expanded business opportunities for the Banks.
 
                                      40
<PAGE>
 
  While client service decisions and day-to-day operations are maintained at
the Banks, Greater Bay offers the advantages of affiliation with a multi-bank
holding company by providing improved access to the capital markets and
expanded client support services, such as business cash management,
international trade services and accounting services. In addition, Greater Bay
provides centralized administrative functions, including support in credit
policy formulation and review, investment management, data processing,
accounting and other specialized support functions thereby allowing the Banks
to focus on client service.
 
CORPORATE GROWTH STRATEGY
 
  The Company's business strategy is to focus on increasing its market share
within the communities it serves through continued internal growth. As a
result of the Merger, the Company has the opportunity to market the
specialized products and services of the Venture Lending Group, the Greater
Bay Trust Company and the SBA Department to a larger customer base. The
Company believes that these products and services, available prior to the
Merger only to customers of CNB, will be attractive to customers and contacts
of MPB in the venture capital community and the high net worth customers of
MPB. The Company believes that the infrastructure developed by Cupertino to
support the Greater Bay Trust Company, the SBA Department and the Venture
Lending Group will allow the Company to offer the products and services of
these groups without significant additional overhead costs.
 
  The Company also will pursue opportunities to expand its market share
through select acquisitions that management believes complement the Company's
businesses. While management would prefer to make acquisitions which would
expand its presence in its current market areas of Santa Clara and San Mateo
Counties, it will also pursue opportunities to expand its market through
acquisitions in other parts of the South, East, and North Bay Areas of San
Francisco.
 
THE BANKS
 
  CNB
 
  CNB presently has four banking offices. CNB's main office is in Cupertino,
and it has one regional office in San Jose and two regional offices in Palo
Alto. At December 31, 1996, CNB had total assets of $339.7 million, total net
loans of $248.4 million and total deposits of $302.3 million.
 
  MPB
 
  MPB presently has three banking offices. MPB's main office is in Palo Alto.
MPB also has regional offices in San Mateo and in San Carlos. On December 31,
1996, MPB had total assets of $282.3 million, total net loans of $193.1
million and total deposits of $257.5 million.
 
  BANKING SERVICES
 
  Through their networks of regional offices, the Banks provide a wide range
of commercial banking services to small and medium-sized businesses, real
estate developers and property managers, business executives, professionals
and other individuals. In addition, the Greater Bay Trust Company provides
trust services to support the trust needs of the Banks' clients.
 
  The Banks offer a wide range of deposit products. These include the normal
range of personal and business checking and savings accounts, time deposits
and individual retirement accounts. The Banks also offer a wide range of
specialized services designed to attract and service the needs of customers
and include cash management and international trade services for business
clients, traveler's checks, safe deposit and MasterCard and Visa merchant
deposits services.
 
  The Banks also engage in the full complement of lending activities,
including commercial, real estate and consumer loans. The Banks provide
commercial loans for working capital and business expansion to small and
medium-sized businesses with annual revenues generally in the range of $1.0
million to $50.0 million. The
 
                                      41
<PAGE>
 
Banks' commercial customers are drawn from a wide variety of manufacturing,
wholesale and service businesses. The Banks provide interim real estate loans
primarily for construction in the Banks' primary service areas of single-
family residences, which typically range between approximately $500,000 and
$1.0 million, and multi-unit projects, which typically range between
approximately $1.5 million and $4.0 million. The Banks provide medium term
commercial real estate loans or credits for the financing of commercial or
industrial buildings where the properties are either used by the owner for
business purposes or have income derived from tenants, which typically range
between approximately $750,000 and $3.0 million. Loans to professionals and
other individual clients cover a full range of consumer services, such as
automobile, aircraft, home improvement and home equity loans, and other
secured and unsecured lines of credit, including credit cards.
 
  Through the SBA Department, loans are made to smaller businesses and are
generally 65% to 80% guaranteed by the SBA. In 1994, CNB was named a Preferred
Lender by the SBA. Preferred Lender status is awarded by the SBA to lenders
who have demonstrated superior ability to generate, underwrite and service
loans guaranteed by the SBA, and results in more rapid turnaround of loan
applications submitted to the SBA for approval.
 
  In May 1994, the Company organized the Venture Lending Group to serve the
needs of companies in their start-up and development phase. This unit was
developed to meet the needs of such clients in the Company's service area by
allowing them to access a banking relationship early in their development. The
loans to this target group of clients are generally secured by the accounts
receivable, inventory and equipment of the companies. The financial strength
of these companies also tends to be bolstered by the presence of venture
capital investors among the shareholders.
 
MARKET AREA
 
  The Banks concentrate on marketing their services to small and medium-sized
businesses, professionals and individuals in the Santa Clara and San Mateo
Counties. Santa Clara County, CNB's primary base of operations, encompasses
the geographic area between San Jose to the south and Palo Alto to the north.
Santa Clara County ranks third in California median household income. CNB is
headquartered in Cupertino, California, which is in the center of the
geographical area referred to as the "Silicon Valley." The city of Cupertino
has a population of approximately 51,300, and its average annual household
income exceeds $97,200. MPB's primary market area ranges from Palo Alto to the
south to South San Francisco to the north. MPB is headquartered in Palo Alto,
California. The city of Palo Alto has a population of approximately 60,000,
and its mean annual household income exceeds $75,000.
 
  The commercial base of Santa Clara and San Mateo Counties is diverse and
includes computer and semiconductor manufacturing, professional services,
printing and publishing, aerospace, defense, real estate construction, as well
as wholesale and retail trade. As a result of its geographic concentration,
the Company's results depend largely upon economic conditions in these areas.
While the economy in the Company's market areas have exhibited positive
economic and employment trends, there is no assurance that such trends will
continue. A deterioration in economic conditions could have material adverse
impact on the quality of the Company's loan portfolio and the demand for its
product and services, and accordingly its results of operations. See "Risk
Factors--Economic Conditions and Geographic Concentration."
 
LENDING ACTIVITIES
 
  UNDERWRITING AND CREDIT ADMINISTRATION
 
  As of the date hereof, the lending activities of each of the Banks is guided
by the basic lending policies established by its Board of Directors. The
Company is currently preparing a new loan policy to govern the lending
activities of both Banks. The new policy is expected to be fully implemented
during the second quarter of 1997. Once implemented, the credit policy will be
approved each year by the Boards of Directors of Greater Bay and each of the
Banks and will be managed through periodic reviews.
 
                                      42
<PAGE>
 
  Each loan must meet minimum underwriting criteria established in the Bank's
lending policy. Lending authority is granted to officers of each Bank on a
limited basis. Loan requests exceeding individual officer approval limits are
approved by the Officers Loan Committees of the respective Banks. Loan
requests exceeding these limits are submitted to the Greater Bay Officers Loan
Committee, which consists of the President and Chief Executive Officer of
Greater Bay, the Executive Vice President and Chief Lending Officer of Greater
Bay, the Executive Vice President and Chief Credit Officer of MPB and the
Senior Vice President and Chief Credit Officer of Greater Bay. Loans requests
which exceed the limits of the Greater Bay Officers Loan Committee are
submitted to the Directors Loan Committee for final approval. The Directors
Loan Committee consists of four outside directors. Each of these committees
meet on a regular basis in order to provide timely responses to the Banks'
clients.
 
  The Company's credit administration function includes an internal review and
the regular use of an outside loan review firm. In addition, the Greater Bay
Officers Loan Committee and Chief Financial Officer meet at a minimum of at
least once a month and review delinquencies, non-performing assets, classified
assets and other pertinent information to evaluate credit risk within each
Bank's loan portfolio and to recommend general reserve percentages and
specific reserve allocations. The information reviewed by this committee is
submitted to the Boards of Directors of the Company on a monthly basis.
 
  LOAN PORTFOLIO
 
  Approximately 57.0% of the Company's gross loan portfolio was in commercial
loans at December 31, 1996, and real estate construction and land loans
represented approximately 17.4% of total loans, primarily for residential
projects. In addition, 16.1% of the Company's loans were real estate term
loans, which are primarily secured by commercial properties. The balance of
the portfolio consists of consumer loans.
 
  The interest rates charged for the loans made by the Banks vary with the
degree of risk, size and maturity of the loans. Rates are generally affected
by competition, associated factors stemming from the client's deposit
relationship with the Bank and the Banks' cost of funds.
 
  Commercial Loans. In their commercial loan portfolio, the Banks provide
personalized financial services to the diverse commercial and professional
businesses in their market areas. Commercial loans, including those made by
the Venture Lending Group, consist primarily of short-term loans (normally
with a maturity of under one year) for working capital and business expansion.
Commercial loans typically include revolving lines of credit collateralized by
inventory, accounts receivable and equipment. Emphasis is placed on the
borrower's earnings history, capitalization, secondary sources of repayment,
and in some instances, third party guarantees or highly liquid collateral
(such as time deposits and investment securities). Commercial loan pricing is
generally at a rate tied to the prime rate (as quoted in the Wall Street
Journal) or the Banks' reference rates.
 
  The Venture Lending Group serves the needs of companies in their start-up
and development phase. Typical clients include technology companies, ranging
from multimedia, software and telecommunications providers to bio-technology
and medical device firms. The Venture Lending Group provides innovative
lending products and other financial services, tailored to the needs of start-
up and growth-stage companies. Borrowings are generally secured by minimum
cash balances, accounts receivable, intellectual property rights, inventory
and equipment of the companies. Many of these companies are in the start-up or
development phase and will not generate any revenues for several years. The
Company will often receive warrants from these companies as part of the
compensation for its services.
 
  The Company participates in many SBA programs and, through CNB, is a
"preferred lender." Preferred lender status is granted to a lender which has
made a certain number of SBA loans and which, in the opinion of the SBA has
staff who are qualified and experienced in this area. As a preferred lender,
the Company has the authority to authorize, on behalf of the SBA, the SBA
guaranty on loans under the 7A program. This can represent a substantial
savings in serving a customer's needs. The Company utilizes both the 504
program, which is focused toward longer-term financing of buildings, and other
long-term assets, and the 7A program which is
 
                                      43
<PAGE>
 
primarily used for financing of the equipment, inventory and working capital
needs of eligible businesses generally over a three- to seven-year term. The
Company's collateral position in the SBA loans is enhanced by the SBA guaranty
in the case of 7A loans, and by lower loan-to-value ratios under the 504
program. The Company generally sells the guaranteed portion of its SBA loans
in the secondary market.
 
  Real Estate Construction and Land Loans. The Banks' real estate construction
loan activity has focused on providing short-term (less than one year
maturity) loans to individuals and developers with whom the Banks have
established relationships for the construction primarily of single family
residences in the Banks' market areas. During 1992 and 1993, the Banks
concentrated their construction loan activity on owner-occupied custom
residences. During 1994, as real estate values began to stabilize, the Banks
also entered the construction loan market for multi-unit single family
residential projects. During 1995 and 1996, the Banks continued to expand
their real estate construction portfolio with the help of the improving real
estate market in Northern California.
 
  Residential real estate construction loans are typically secured by first
deeds of trust and require guarantees of the borrower. The economic viability
of the project and the borrower's credit-worthiness are primary considerations
in the loan underwriting decision. Generally, these loans provide an
attractive yield, but may carry a higher than normal risk of loss or
delinquency, particularly if general real estate values decline. The Banks
utilize approved independent local appraisers and loan-to-value ratios which
generally do not exceed 65% to 75% of the appraised value of the property. The
Banks monitor projects during the construction phase through regular
construction inspections and a disbursement program tied to the percentage of
completion of each project.
 
  The Banks also occasionally make land loans to person who intend to
construct a single family residence on the lot generally within twelve months.
In addition, the Banks have occasionally in the past, and may to a greater
extent in the future, make commercial real estate construction loans to high
net worth clients with adequate liquidity for construction of office and
warehouse properties. Such loans are typically secured by first deeds of trust
and require guarantees of the borrower.
 
  Commercial Real Estate Term Loans. The Banks provide medium term commercial
real estate loans secured by commercial or industrial buildings where the
properties are either used by the owner for business purposes ("owner-user
properties") or have income derived from tenants ("investment properties").
The Company's loan policies require the principal balance of the loan,
generally between $750,000 and $1.5 million, to be no more than 70% of the
stabilized appraised value of the underlying real estate collateral. The
loans, which are typically secured by first deeds of trust only, generally
have terms of no more than seven to ten years and are amortized over 20 years.
Most of these loans have rates tied to the prime rate, with many adjusting
whenever the prime rate changes; the remaining loans adjust every two or three
years depending on the term of the loan.
 
  Consumer and Other Loans. The Banks' consumer and other loan portfolio is
divided between installment loans secured by automobiles and aircraft, and
home improvement loans and equity lines of credit which are often secured by
residential real estate. Installment loans tend to be fixed rate and longer-
term (one-to-five year maturity), while the equity lines of credit and home
improvement loans are generally floating rate and are reviewed for renewal on
an annual basis. The Banks also have a minimal portfolio of credit card loans,
issued as an additional service to its clients.
 
DEPOSITS
 
  The Banks' deposits are obtained primarily from small and medium-sized
businesses, business executives, professionals and other individuals. Each of
the Banks offers the usual and customary range of depository products provided
by commercial banks. The Banks' deposits are not received from a single
depositor or group of affiliated depositors, the loss of any one of which
would have a material adverse effect on the business of the Company or either
of the Banks. Rates paid on deposits vary among the categories of deposits due
to different terms, the size of the individual deposit, and rates paid by
competitors on similar deposits.
 
  CNB has two business units that provide significant support to its deposit
base. The Greater Bay Trust Company has approximately 10% of its trust assets
under management in liquid funds that are retained in CNB
 
                                      44
<PAGE>
 
money market demand accounts. At December 31, 1996, these funds totaled $41.7
million. The Venture Lending Group, which finances companies in their
development stage, is another source of deposits as most of the start-up phase
companies have significant liquidity that is deposited in the bank as part of
the banking relationship. At December 31, 1996, customers of the Venture
Lending Group had $38.1 million in deposits at CNB.
 
TRUST DEPARTMENT
 
  The Greater Bay Trust Company commenced operations in July 1988. The Greater
Bay Trust Company offers a full range of fee-based trust services directly to
its clients and administers several types of retirement plans, including
corporate pension plans, 401(k) plans and individual retirement plans, with an
emphasis on the investment management, custodianship and trusteeship of such
plans. In addition, the Greater Bay Trust Company acts as executor,
administrator, guardian and/or trustee in the administration of the estates of
individuals. Investment and custodial services are provided for corporations,
individuals and nonprofit organizations. Total assets under management by the
Greater Bay Trust Company were approximately $418.0 million at December 31,
1996, compared to $270.0 million at December 31, 1995 and $157.0 million at
December 31, 1994.
 
COMPETITION
 
  The banking and financial services business in California generally, and in
the Banks' market areas specifically, is highly competitive. The increasingly
competitive environment is a result primarily of changes in regulation,
changes in technology and product delivery systems, and the accelerating pace
of consolidation among financial services providers. The Banks compete for
loans, deposits and customers for financial services with other commercial
banks, savings and loan associations, securities and brokerage companies,
mortgage companies, insurance companies, finance companies, money market
funds, credit unions, and other nonbank financial service providers. Many of
these competitors are much larger in total assets and capitalization, have
greater access to capital markets and offer a broader array of financial
services than the Banks. In order to compete with the other financial services
providers, the Banks principally rely upon local promotional activities,
personal relationships established by officers, directors and employees with
its customers, and specialized services tailored to meet its customers' needs.
In those instances where the Banks are unable to accommodate a customer's
needs, the Banks may arrange for those services to be provided by its
correspondents. The Bank have seven offices located in the Santa Clara and San
Mateo Counties. Neither the deposits nor loans of the offices of the
respective Banks exceed 1% of all financial services companies located in such
counties.
 
EMPLOYEES
 
  At December 31, 1996, the Company had 177 full-time employees. None of the
employees are covered by a collective bargaining agreement. The Company
considers its employee relations to be satisfactory.
 
PROPERTIES
 
  The Company occupies its administrative office under a lease which expires
2002. MPB occupies its offices under leases expiring at various dates
(including options to renew) through 2009. CNB occupies its offices under
leases expiring at various dates (including options to renew) through 2018.
 
  The Company believes its present facilities are adequate for its present
needs and anticipated future growth. The Company believes that, if necessary,
it could secure suitable alternative facilities on similar terms without
adversely affecting operations.
 
LEGAL PROCEEDINGS
 
  There are no material legal proceedings pending other than ordinary routine
litigation incidental to the business of the Company to which Greater Bay or
the Banks is a party or of which any of their property is a subject.

                          SUPERVISION AND REGULATION
 
  Bank holding companies and banks are extensively regulated under both
federal and state law. Set forth below is a summary description of certain
laws which relate to the regulation of Greater Bay and the Banks. The
description does not purport to be complete and is qualified in its entirety
by reference to the applicable laws and regulations.
 
GREATER BAY
 
  Greater Bay, as a registered bank holding company, is subject to regulation
under the Bank Holding Company Act of 1956, as amended (the "BHCA"). Greater
Bay is required to file with the Federal Reserve quarterly and annual reports
and such additional information as the Federal Reserve may require pursuant to
the BHCA. The Federal Reserve may conduct examinations of Greater Bay and its
subsidiaries.
 
  The Federal Reserve may require that Greater Bay terminate an activity or
terminate control of or liquidate or divest certain subsidiaries or affiliates
when the Federal Reserve believes the activity or the control of the
subsidiary or affiliate constitutes a significant risk to the financial
safety, soundness or stability of any of its banking subsidiaries. The Federal
Reserve also has the authority to regulate provisions of certain bank holding
company debt, including authority to impose interest ceilings and reserve
requirements on such debt. Under certain circumstances, Greater Bay must file
written notice and obtain approval from the Federal Reserve prior to
purchasing or redeeming its equity securities. Further, Greater Bay is
required by the Federal Reserve to maintain certain levels of capital. See "--
Capital Standards" herein.
 
  Greater Bay is required to obtain the prior approval of the Federal Reserve
for the acquisition of more than 5% of the outstanding shares of any class of
voting securities or substantially all of the assets of any bank or bank
holding company. Prior approval of the Federal Reserve is also required for
the merger or consolidation of Greater Bay and another bank holding company.
 
  Greater Bay is prohibited by the BHCA, except in certain statutorily
prescribed instances, from acquiring direct or indirect ownership or control
of more than 5% of the outstanding voting shares of any company that is not a
bank or bank holding company and from engaging directly or indirectly in
activities other than those of banking, managing or controlling banks or
furnishing services to its subsidiaries. However, Greater Bay, subject to the
prior approval of the Federal Reserve, may engage in any, or acquire shares of
companies engaged in, activities that are deemed by the Federal Reserve to be
so closely related to banking or managing or controlling banks as to be a
proper incident thereto. In making any such determination, the Federal Reserve
is required to consider whether the performance of such activities by Greater
Bay or an affiliate can reasonably be expected to produce benefits to the
public, such as greater convenience, increased competition or gains in
efficiency, that outweigh possible adverse effects, such as undue
concentration of resources, decreased or unfair competition, conflicts of
interest or unsound banking practices. The Federal Reserve is also empowered
to differentiate between activities commenced de novo and activities commenced
by acquisition, in whole or in part, of a going concern. In 1996, the Economic
Growth and Regulatory Paperwork Reduction Act of 1996 (the "Budget Act")
eliminated the requirement that bank holding companies seek Federal Reserve
approval before engaging de novo in permissible nonbanking activities listed
in Regulation Y, which governs bank holding companies, if the holding company
and its lead depository institution are well-managed and well-capitalized and
certain other criteria specified in the statute are met. For purposes of
determining the capital levels at which a bank holding company shall be
considered "well-capitalized" under this section of the Budget Act and
Regulation Y, the Federal Reserve adopted, as a rule, risk-based capital
ratios (on a consolidated basis) that are the same as the levels set for
determining that a state member bank is well capitalized under the provisions
established under the prompt corrective action provisions of federal law. See
"--Prompt Corrective Action and Other Enforcement Mechanisms" herein.
 
  Under Federal Reserve regulations, a bank holding company is required to
serve as a source of financial and managerial strength to its subsidiary banks
and may not conduct its operations in an unsafe or unsound
 
                                      46
<PAGE>
 
manner. In addition, it is the Federal Reserve's policy that in serving as a
source of strength to its subsidiary banks, a bank holding company should
stand ready to use available resources to provide adequate capital funds to
its subsidiary banks during periods of financial stress or adversity and
should maintain the financial flexibility and capital-raising capacity to
obtain additional resources for assisting its subsidiary banks. A bank holding
company's failure to meet its obligations to serve as a source of strength to
its subsidiary banks will generally be considered by the Federal Reserve to be
an unsafe and unsound banking practice or a violation of the Federal Reserve's
regulations or both.
 
  Greater Bay is also a bank holding company within the meaning of Section
3700 of the California Financial Code. As such, Greater Bay and its
subsidiaries are subject to examination by, and may be required to file
reports with, the California State Banking Department.
 
  Finally, Greater Bay is subject to the periodic reporting requirements of
the Exchange Act, including, but not limited to, filing annual, quarterly and
other current reports with the Commission.
 
THE BANKS
 
  CNB, as a national banking association, is subject to primary supervision,
examination and regulation by the Comptroller. MPB, as a California state
chartered bank and member of the Federal Reserve System, is subject to primary
supervision, periodic examination and regulation by the California
Superintendent of Banks ("Superintendent") and the Federal Reserve. If, as a
result of an examination of a bank, the bank regulatory agencies should
determine that the financial condition, capital resources, asset quality,
earnings prospects, management, liquidity or other aspects of the bank's
operations are unsatisfactory or that the bank or its management is violating
or has violated any law or regulation, various remedies are available to the
bank regulatory agencies. Such remedies include the power to enjoin "unsafe or
unsound" practices, to require affirmative action to correct any conditions
resulting from any violation or practice, to issue an administrative order
that can be judicially enforced, to direct an increase in capital, to restrict
the growth of the bank, to assess civil monetary penalties, to remove officers
and directors and ultimately to terminate a bank's deposit insurance, which
would result in a revocation of the bank's charter. Neither CNB nor MPB has
been the subject of any such actions by their respective regulatory agencies.
 
  The deposits of the Banks are insured by the FDIC in the manner and to the
extent provided by law. For this protection, the Banks pay a semiannual
statutory assessment. See "--Premiums for Deposit Insurance" herein.
 
  Various requirements and restrictions under the laws of the State of
California and the United States affect the operations of the Banks. State and
federal statutes and regulations relate to many aspects of the Banks'
operations, including levels of capital, reserves against deposits, interest
rates payable on deposits, loans, investments, mergers and acquisitions,
borrowings, dividends, locations of branch offices and capital requirements.
 
RESTRICTIONS ON TRANSFERS OF FUNDS TO GREATER BAY BY THE BANKS
 
  Greater Bay is a legal entity separate and distinct from the Banks. Greater
Bay's ability to pay cash dividends is limited by state law.
 
  There are statutory and regulatory limitations on the amount of dividends
which may be paid to Greater Bay by the Banks. California law restricts the
amount available for cash dividends by state chartered banks, such as MPB, to
the lesser of retained earnings or the bank's net income for its last three
fiscal years (less any distributions made to shareholders by the bank or by
any majority-owned subsidiary of the bank during such period). Notwithstanding
this restriction, a bank may, with the prior approval of the Superintendent,
make a distribution to its shareholders in an amount not exceeding the greater
of the retained earnings of the bank, net income for such bank's last fiscal
year or the net income of the bank for its current year. The prior approval of
 
                                      47
<PAGE>
 
the Comptroller is required if the total of all dividends declared by a
national bank, such as CNB, in any calendar year exceeds the bank's net
profits (as defined) for that year combined with its retained net profits (as
defined) for the preceding two years, less any required transfers to surplus
or a fund for the retirement of any preferred stock.
 
  The bank regulatory agencies also have authority to prohibit banks from
engaging in activities that, in their respective opinions, constitute unsafe
or unsound practices in conducting its business. It is possible, depending
upon the financial condition of the bank in question and other factors, that
the bank regulatory agencies could assert that the payment of dividends or
other payments might, under some circumstances, be such an unsafe or unsound
practice. Further, the bank regulatory agencies have established guidelines
with respect to the maintenance of appropriate levels of capital by banks or
bank holding companies under their jurisdiction. Compliance with the standards
set forth in such guidelines and the restrictions that are or may be imposed
under the prompt corrective action provisions of federal law could limit the
amount of dividends which the Banks or Greater Bay may pay. See "--Prompt
Corrective Regulatory Action and Other Enforcement Mechanisms" herein and "--
Capital Standards" herein for a discussion of these additional restrictions on
capital distributions.
 
  Substantially all of Greater Bay's revenues, including funds available for
the payment of dividends and other operating expenses, are, and will continue
to be, dividends paid by the Banks. At December 31, 1996, the Banks had $6.3
million in the aggregate available for the payment of cash dividends.
 
  The Banks are subject to certain restrictions imposed by federal law on any
extensions of credit to, or the issuance of a guarantee or letter of credit on
behalf of, Greater Bay or other affiliates, the purchase of or investments in
stock or other securities thereof, the taking of such securities as collateral
for loans and the purchase of assets of Greater Bay or other affiliates. Such
restrictions prevent Greater Bay and such other affiliates from borrowing from
the Banks unless the loans are secured by marketable obligations or other
acceptable collateral of designated amounts. Further, such secured loans and
investments by the Banks to or in Greater Bay or to or in any other affiliate
is limited to 10% of the respective bank's capital stock and surplus (as
defined by federal regulations) and such secured loans and investments are
limited, in the aggregate, to 20% of the respective banks' capital stock and
surplus (as defined by federal regulations). California law also imposes
certain restrictions with respect to transactions involving Greater Bay and
other controlling persons of the Banks. Additional restrictions on
transactions with affiliates may be imposed on the Banks under the prompt
corrective action provisions of federal law. See "--Prompt Corrective
Regulatory Action and Other Enforcement Mechanisms."
 
COMMON LIABILITY
 
  Under federal law, a depository institution insured by the FDIC can be held
liable for any loss incurred by, or reasonably expected to be incurred by, the
FDIC in connection with the default of a commonly controlled FDIC-insured
depository institution or any assistance provided by the FDIC to a commonly
controlled FDIC-insured institution in danger of default. These provisions can
have the effect of making one subsidiary bank of Greater Bay responsible for
FDIC-insured losses at another subsidiary bank.
 
EFFECT OF GOVERNMENTAL POLICIES AND LEGISLATION
 
  Banking is a business that depends on rate differentials. In general, the
difference between the interest rate paid by the Banks on their deposits and
their other borrowings and the interest rate received by the Banks on loans
extended to their customers and securities held in the Banks' portfolios
comprises the major portion of the Banks' earnings. These rates are highly
sensitive to many factors that are beyond the control of the Banks.
Accordingly, the earnings and growth of the Banks are subject to the influence
of domestic and foreign economic conditions, including inflation, recession
and unemployment.
 
  The commercial banking business is not only affected by general economic
conditions but is also influenced by the monetary and fiscal policies of the
federal government and the policies of regulatory agencies, particularly
 
                                      48
<PAGE>
 
the Federal Reserve. The Federal Reserve implements national monetary policies
(with objectives such as curbing inflation and combating recession) by its
open-market operations in United States Government securities, by adjusting
the required level of reserves for financial institutions subject to its
reserve requirements and by varying the discount rates applicable to
borrowings by depository institutions. The actions of the Federal Reserve in
these areas influence the growth of bank loans, investments and deposits and
also affect interest rates charged on loans and paid on deposits. The nature
and impact of any future changes in monetary policies cannot be predicted.
 
  From time to time, legislation is enacted which has the effect of increasing
the cost of doing business, limiting or expanding permissible activities or
affecting the competitive balance between banks and other financial services
providers. Proposals to change the laws and regulations governing the
operations and taxation of banks, bank holding companies and other financial
services provider are frequently made in Congress, in the California
legislature and before various bank regulatory and other professional
agencies. The likelihood of any major legislative changes and the impact such
changes might have on Greater Bay or the Banks are impossible to predict.
 
CAPITAL STANDARDS
 
  The Federal Reserve, the Comptroller and the FDIC have adopted risk-based
minimum capital guidelines intended to provide a measure of capital that
reflects the degree of risk associated with a banking organization's
operations for both transactions reported on the balance sheet as assets and
transactions, such as letters of credit and recourse arrangements, which are
recorded as off balance sheet items. Under these guidelines, nominal dollar
amounts of assets and credit equivalent amounts of off balance sheet items are
multiplied by one of several risk adjustment percentages, which range from 0%
for assets with low credit risk, such as certain U.S. Treasury securities, to
100% for assets with high credit risk, such as commercial loans.
 
  A banking organization's risk-based capital ratios are obtained by dividing
its qualifying capital by its total risk adjusted assets. The regulators
measure risk-adjusted assets, which includes off balance sheet items, against
both total qualifying capital (the sum of Tier 1 capital and limited amounts
of Tier 2 capital) and Tier 1 capital. Tier 1 capital consists of, among other
things, (i) common shareholders' equity capital (includes common stock and
related surplus, and undivided profits); (ii) noncumulative perpetual
preferred stock (cumulative perpetual preferred stock for bank holding
companies), including any related surplus; and (iii) minority interests in
certain subsidiaries, less most intangible assets. Tier 2 capital may consist
of: (i) a limited amount of the allowance for loan and lease losses ("ALLL");
(ii) cumulative perpetual preferred stock; (iii) perpetual preferred stock
(and any related surplus); (iv) term subordinated debt and certain other
instruments with some characteristics of equity. The inclusion of elements of
Tier 2 capital is subject to certain other requirements and limitations of the
federal banking agencies. The federal banking agencies require a minimum ratio
of qualifying total capital to risk-adjusted assets of 8% and a minimum ratio
of Tier 1 capital to risk-adjusted assets of 4%.
 
  In addition to the risked-based guidelines, federal banking regulators
require banking organizations to maintain a minimum amount of Tier 1 capital
to total assets, referred to as the leverage ratio. For a banking organization
rated in the highest of the five categories used by regulators to rate banking
organizations, the minimum leverage ratio of Tier 1 capital to total assets
must be 3%. For all banking organizations not rated in the highest category,
the minimum leverage ratio must be at least 100 to 200 basis points above the
3% minimum, or 4% to 5%. In addition to these uniform risk-based capital
guidelines and leverage ratios that apply across the industry, the regulators
have the discretion to set individual minimum capital requirements for
specific institutions at rates significantly above the minimum guidelines and
ratios.
 
  In June 1996, the federal banking agencies adopted a joint agency policy
statement to provide guidance on managing interest rate risk. These agencies
indicated that the adequacy and effectiveness of a bank's interest rate risk
management process and the level of its interest rate exposures are critical
factors in the agencies' evaluation of the bank's capital adequacy. A bank
with material weaknesses in its risk management process or high levels of
exposure relative to its capital will be directed by the agencies to take
corrective action. Such actions will
 
                                      49
<PAGE>
 
include recommendations or directions to raise additional capital, strengthen
management expertise, improve management information and measurement systems,
reduce levels of exposure, or some combination thereof depending upon the
individual institution's circumstances. This policy statement augments the
August 1995 regulations adopted by the federal banking agencies which
addressed risk-based capital standards for interest rate risk.
 
  In December 1993, the federal banking agencies issued an interagency policy
statement on the ALLL which, among other things, establishes certain benchmark
ratios of loan loss reserves to classified assets. The benchmark set forth by
such policy statement is the sum of (a) assets classified loss; (b) 50 percent
of assets classified doubtful; (c) 15 percent of assets classified
substandard; and (d) estimated credit losses on other assets over the upcoming
12 months. This amount is neither a "floor" nor a "safe harbor" level for an
institution's ALLL.
 
  Federally supervised banks and savings associations are currently required
to report deferred tax assets in accordance with SFAS No. 109. The federal
banking agencies issued final rules governing banks and bank holding
companies, which became effective April 1, 1995 and limit the amount of
deferred tax assets that are allowable in computing an institution's
regulatory capital. Deferred tax assets that can be realized for taxes paid in
prior carryback years and from future reversals of existing taxable temporary
differences are generally not limited. Deferred tax assets that can only be
realized through future taxable earnings are limited for regulatory capital
purposes to the lesser of (i) the amount that can be realized within one year
of the quarter-end report date, based on projected taxable income for that
year or (ii) 10% of Tier 1 Capital. The amount of any deferred tax in excess
of this limit would be excluded from Tier 1 Capital and total assets and
regulatory capital calculations.
 
  Future changes in regulations or practices could further reduce the amount
of capital recognized for purposes of capital adequacy. Such a change could
affect the ability of the Banks to grow and could restrict the amount of
profits, if any, available for the payment of dividends. For information
concerning the capital ratios of Greater Bay and the Banks, see "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Capital Resources."
 
PROMPT CORRECTIVE ACTION AND OTHER ENFORCEMENT MECHANISMS
 
  Federal law requires each federal banking agency to take prompt corrective
action to resolve the problems of insured depository institutions, including
but not limited to those that fall below one or more prescribed minimum
capital ratios. In accordance with federal law, each federal banking agency
has promulgated regulations defining the following five categories in which an
insured depository institution will be placed, based on the level of its
capital ratios: well capitalized, adequately capitalized, undercapitalized,
significantly undercapitalized and critically undercapitalized. An insured
depository institution will be classified in the following categories based,
in part, on the capital measures indicated below:
 
<TABLE>
<S>                                  <C>
  "Well capitalized"                 "Adequately capitalized"
  Total risk-based capital of at
   least 10%;                        Total risk-based capital of at least 8%;
  Tier 1 risk-based capital of 6%;
   and                               Tier 1 risk-based capital of 4%; and
  Leverage ratio of 5%.              Leverage ratio of 4%.
  "Undercapitalized"                 "Significantly undercapitalized"
  Total risk-based capital less than
   8%;                               Total risk-based capital less than 6%;
  Tier 1 risk-based capital less
   than 4%; or                       Tier 1 risk-based capital less than 3%; or
  Leverage ratio less than 4%.       Leverage ratio less than 3%.
  "Critically undercapitalized"
  Tangible equity to total assets
   less than 2%.
</TABLE>
 
                                      50
<PAGE>
 
  An institution that, based upon its capital levels, is classified as "well
capitalized," "adequately capitalized" or "undercapitalized" may be treated as
though it were in the next lower capital category if the appropriate federal
banking agency, after notice and opportunity for hearing, determines that an
unsafe or unsound condition or an unsafe or unsound practice warrants such
treatment. At each successive lower capital category, an insured depository
institution is subject to more restrictions. The federal banking agencies,
however, may not treat a significantly undercapitalized institution as
"critically undercapitalized" unless its capital ratio actually warrants such
treatment.
 
  The law prohibits insured depository institutions from paying management
fees to any controlling persons or, with certain limited exceptions, making
capital distributions if after such transaction the institution would be
undercapitalized. If an insured depository institution is undercapitalized, it
will be closely monitored by the appropriate federal banking agency, subject
to asset growth restrictions and required to obtain prior regulatory approval
for acquisitions, branching and engaging in new lines of business. Any
undercapitalized depository institution must submit an acceptable capital
restoration plan to the appropriate federal banking agency 45 days after
receiving notice, or is deemed to have notice, that the institution is
undercapitalized. The appropriate federal banking agency cannot accept a
capital plan unless, among other things, it determines that the plan: (i)
specifies: (a) the steps the institution will take to become adequately
capitalized; (b) the levels of capital to be attained during each year in
which the plan will be in effect; (c) how the institution will comply with the
applicable restrictions or requirements then in effect of the Federal Deposit
Insurance Act; and (d) the types and levels of activities in which the
institution will engage; (ii) is based on realistic assumptions and is likely
to succeed in restoring the depository institution's capital; and (iii) would
not appreciably increase the risk (including credit risk, interest-rate risk,
and other types of risk) to which the institution is exposed. In addition,
each company controlling an undercapitalized depository institution must
guarantee that the institution will comply with the capital plan until the
depository institution has been adequately capitalized on average during each
of four consecutive calendar quarters and must otherwise provide appropriate
assurances of performance. The aggregate liability of such guarantee is
limited to the lesser of (a) an amount equal to 5% of the depository
institution's total assets at the time the institution became undercapitalized
or (b) the amount which is necessary to bring the institution into compliance
with all capital standards applicable to such institution as of the time the
institution fails to comply with its capital restoration plan. Finally, the
appropriate federal banking agency may impose any of the additional
restrictions or sanctions that it may impose on significantly undercapitalized
institutions if it determines that such action will further the purpose of the
prompt correction action provisions.
 
  An insured depository institution that is significantly undercapitalized, or
is undercapitalized and fails to submit, or in a material respect to
implement, an acceptable capital restoration plan, is subject to additional
restrictions and sanctions. These include, among other things: (i) a forced
sale of voting shares to raise capital or, if grounds exist for appointment of
a receiver or conservator, a forced merger; (ii) restrictions on transactions
with affiliates; (iii) further limitations on interest rates paid on deposits;
(iv) further restrictions on growth or required shrinkage; (v) modification or
termination of specified activities; (vi) replacement of directors or senior
executive officers; (vii) prohibitions on the receipt of deposits from
correspondent institutions; (viii) restrictions on capital distributions by
the holding companies of such institutions; (ix) required divestiture of
subsidiaries by the institution; or (x) other restrictions as determined by
the appropriate federal banking agency. Although the appropriate federal
banking agency has discretion to determine which of the foregoing restrictions
or sanctions it will seek to impose, it is required to: (i) force a sale of
shares or obligations of the bank, or require the bank to be acquired by or
combine with another institution; (ii) impose restrictions on affiliate
transactions and (iii) impose restrictions on rates paid on deposits, unless
it determines that such actions would not further the purpose of the prompt
corrective action provisions. In addition, without the prior written approval
of the appropriate federal banking agency, a significantly undercapitalized
institution may not pay any bonus to its senior executive officers or provide
compensation to any of them at a rate that exceeds such officer's average rate
of base compensation during the 12 calendar months preceding the month in
which the institution became undercapitalized.
 
  Further restrictions and sanctions are required to be imposed on insured
depository institutions that are critically undercapitalized. For example, a
critically undercapitalized institution generally would be prohibited
 
                                      51
<PAGE>
 
from engaging in any material transaction other than in the ordinary course of
business without prior regulatory approval and could not, with certain
exceptions, make any payment of principal or interest on its subordinated debt
beginning 60 days after becoming critically undercapitalized. Most
importantly, however, except under limited circumstances, the appropriate
federal banking agency, not later than 90 days after an insured depository
institution becomes critically undercapitalized, is required to appoint a
conservator or receiver for the institution. The board of directors of an
insured depository institution would not be liable to the institution's
shareholders or creditors for consenting in good faith to the appointment of a
receiver or conservator or to an acquisition or merger as required by the
regulator.
 
  In addition to measures taken under the prompt corrective action provisions,
commercial banking organizations may be subject to potential enforcement
actions by the federal regulators for unsafe or unsound practices in
conducting their businesses or for violations of any law, rule, regulation or
any condition imposed in writing by the agency or any written agreement with
the agency. See "--Potential Enforcement Actions" herein.
 
SAFETY AND SOUNDNESS STANDARDS
 
  Effective July 1995, the federal banking agencies adopted final guidelines
establishing standards for safety and soundness, as required by Federal
Deposit Insurance Corporation Improvement Act. These standards are designed to
identify potential safety and soundness concerns and ensure that action is
taken to address those concerns before they pose a risk to the deposit
insurance funds. The standards relate to (i) internal controls, information
systems and internal audit systems; (ii) loan documentation; (iii) credit
underwriting; (iv) asset growth; (v) earnings; and (vi) compensation, fee and
benefits. If a federal banking agency determines that an institution fails to
meet any of these standards, the agency may require the institution to submit
to the agency an acceptable plan to achieve compliance with the standard. In
the event the institution fails to submit an acceptable plan within the time
allowed by the agency or fails in any material respect to implement an
accepted plan, the agency must, by order, require the institution to correct
the deficiency. Effective October 1, 1996, the federal banking agencies
promulgated safety and soundness regulations and accompanying interagency
compliance guidelines on asset quality and earnings standards. These new
guidelines provide six standards for establishing and maintaining a system to
identify problem assets and prevent those assets from deteriorating. The
institution should: (i) conduct periodic asset quality reviews to identify
problem assets; (ii) estimate the inherent losses in those assets and
establish reserves that are sufficient to absorb estimated losses; (iii)
compare problem asset totals to capital; (iv) take appropriate corrective
action to resolve problem assets; (v) consider the size and potential risks of
material asset concentrations; and (vi) provide periodic asset reports with
adequate information for management and the board of directors to assess the
level of asset risk. These new guidelines also set forth standards for
evaluating and monitoring earnings and for ensuring that earnings are
sufficient for the maintenance of adequate capital and reserves. If an
institution fails to comply with a safety and soundness standard, the
appropriate federal banking agency may require the institution to submit a
compliance plan. Failure to submit a compliance plan or to implement an
accepted plan may result in enforcement action.
 
PREMIUMS FOR DEPOSIT INSURANCE
 
  The FDIC has adopted final regulations implementing a risk-based premium
system required by federal law, which establishes an assessment rate schedule
ranging from 0 cents per $100 of deposits to 27 cents per $100 of deposits
applicable to members of BIF. To determine the risk-based assessment for each
institution, the FDIC will categorize an institution as well capitalized,
adequately capitalized or undercapitalized based on its capital ratios using
the same standards used by the FDIC for its prompt corrective action
regulations. A well-capitalized institution is generally one that has at least
a 10% total risk-based capital ratio, a 6% Tier 1 risk-based capital ratio and
a 5% Tier 1 leverage capital ratio. An adequately capitalized institution will
generally have at least an 8% total risk-based capital ratio, a 4% Tier 1
risk-based capital ratio and a 4% Tier 1 leverage capital ratio. An
undercapitalized institution will generally be one that does not meet either
of the above definitions. The FDIC will also assign each institution to one of
three subgroups based upon reviews by the institution's primary federal or
state regulator, statistical analyses of financial statements and other
information relevant to evaluating the risk
 
                                      52
<PAGE>
 
posed by the institution. The three supervisory categories are: financially
sound with only a few minor weaknesses (Group A), demonstrates weaknesses that
could result in significant deterioration (Group B), and poses a substantial
probability of loss (Group C).
 
  The BIF assessment rates are set forth below for institutions based on their
risk-based assessment categorization.

*Assessment figures are expressed in terms of cents per $100 per deposits.
 
  On September 30, 1996, Congress passed the Budget Act which capitalized the
Savings Association Insurance Fund ("SAIF") through a special assessment on
SAIF-insured deposits and required banks to share in part of the interest
payments on the Financing Corporation ("FICO") bonds which were issued to help
fund the federal government costs associated with the savings and loan crisis
of the late 1980's. The special thrift SAIF assessment has been set at 65.7
cents per $100 of deposits insured by SAIF as of March 31, 1995. Effective
January 1, 1997, for the FICO payments, SAIF-insured institutions will pay 3.2
cents per $100 in domestic deposits and BIF-insured institutions, like the
Banks, will pay 0.64 cents per $100 in domestic deposits. Full pro rata
sharing of the FICO interest payments takes effect on January 1, 2000.
 
  The federal banking regulators are also authorized to prohibit depository
institutions and their holding companies from facilitating or encouraging the
shifting of deposits from SAIF to BIF for the purpose of evading thrift
assessment rates. The Budget Act also prohibits the FDIC from setting premiums
under the risk-based schedule above the amount needed to meet the designated
reserve ratio (currently 1.25%).
 
INTERSTATE BANKING AND BRANCHING
 
  On September 29, 1994, the President signed into law the Riegle-Neal
Interstate Banking and Branching Efficiency Act of 1994 (the "Interstate
Act"). Under the Interstate Act, beginning one year after the date of
enactment, a bank holding company that is adequately capitalized and managed
may obtain approval under the BHCA to acquire an existing bank located in
another state without regard to state law. A bank holding company is not
permitted to make such an acquisition if, upon consummation, it would control
(a) more than 10% of the total amount of deposits of insured depository
institutions in the United States or (b) 30% or more of the deposits in the
state in which the bank is located. A state may limit the percentage of total
deposits that may be held in that state by any one bank or bank holding
company if application of such limitation does not discriminate against out-
of-state banks or bank holding companies. An out-of-state bank holding company
may not acquire a state bank in existence for less than a minimum length of
time that may be prescribed by state law, except that a state may not impose
more than a five-year age requirement.
 
  The Interstate Act also permits, beginning June 1, 1997, mergers of insured
banks located in different states and conversion of the branches of the
acquired bank into branches of the resulting bank. Each state may permit such
combinations earlier than June 1, 1997, and may adopt legislation to prohibit
interstate mergers after that date in that state or in other states by that
state's banks. The same concentration limits discussed in the preceding
paragraph apply. The Interstate Act also permits a national or state bank to
establish branches in a state other than its home state if permitted by the
laws of that state, subject to the same requirements and conditions as for a
merger transaction.
 
                                      53
<PAGE>
 
  The Interstate Act is likely to increase competition in the Company's market
areas especially from larger financial institutions and their holding
companies. It is difficult to assess the impact such likely increased
competition will have on the Company's operations.
 
  Under the Interstate Act, the extent of a commercial bank's ability to
branch into a new state will depend on the law of the state. In October 1995,
California adopted an early "opt in" statute under the Interstate Act that
permits out-of-state banks to acquire California banks that satisfy a five-
year minimum age requirement (subject to exceptions for supervisory
transactions) by means of merger or purchases of assets, although entry
through acquisition of individual branches of California institutions and de
novo branching into California are not permitted. The Interstate Act and the
California branching statute will likely increase competition from out-of-
state banks in the markets in which the Company operates, although it is
difficult to assess the impact that such increased competition may have on the
Company's operations.
 
COMMUNITY REINVESTMENT ACT AND FAIR LENDING DEVELOPMENTS
 
  The Banks are subject to certain fair lending requirements and reporting
obligations involving home mortgage lending operations and Community
Reinvestment Act ("CRA") activities. The CRA generally requires the federal
banking agencies to evaluate the record of a financial institution in meeting
the credit needs of its local communities, including low and moderate income
neighborhoods. In addition to substantial penalties and corrective measures
that may be required for a violation of certain fair lending laws, the federal
banking agencies may take compliance with such laws and CRA into account when
regulating and supervising other activities.
 
  In May 1995, the federal banking agencies issued final regulations which
change the manner in which they measure a bank's compliance with its CRA
obligations. The final regulations adopt a performance-based evaluation system
which bases CRA ratings on an institution's actual lending, service and
investment performance, rather than the extent to which the institution
conducts needs assessments, documents community outreach activities or
complies with other procedural requirements.
 
  In March 1994, the federal Interagency Task Force on Fair Lending issued a
policy statement on discrimination in lending. The policy statement describes
the three methods that federal agencies will use to prove discrimination:
overt evidence of discrimination, evidence of disparate treatment and evidence
of disparate impact.
 
  In connection with its assessment of CRA performance, the appropriate bank
regulatory agency assigns a rating of "outstanding," "satisfactory," "needs to
improve" or "substantial noncompliance." Based on an examination conducted
during the first quarter of 1996, MPB was rated outstanding. CNB, which was
rated satisfactory in 1995, is currently undergoing a CRA exam.
 
POTENTIAL ENFORCEMENT ACTIONS
 
  Commercial banking organizations, such as the Banks, and their institution-
affiliated parties, which include Greater Bay, may be subject to potential
enforcement actions by the Federal Reserve, the FDIC, the Superintendent
and/or the Comptroller for unsafe or unsound practices in conducting their
businesses or for violations of any law, rule, regulation or any condition
imposed in writing by the agency or any written agreement with the agency.
Enforcement actions may include the imposition of a conservator or receiver,
the issuance of a cease-and-desist order that can be judicially enforced, the
termination of insurance of deposits (in the case of the Banks), the
imposition of civil money penalties, the issuance of directives to increase
capital, the issuance of formal and informal agreements, the issuance of
removal and prohibition orders against institution affiliated parties and the
imposition of restrictions and sanctions under the prompt corrective action
provisions of the FDIC Improvement Act. Additionally, a holding company's
inability to serve as a source of strength to its subsidiary banking
organizations could serve as an additional basis for a regulatory action
against the holding company. Neither Greater Bay nor the Banks has been
subject to any such enforcement actions.

(1) Potential gains are net of exercise price, but before taxes associated
    with exercise. These amounts represent certain assumed rates of
    appreciation only, based on Securities and Exchange Commission (the
    "Commission") rules. Actual gains, if any, on stock option exercises are
    dependent on the future performance of the Common Stock, overall market
    conditions and the optionholders' continued employment through the vesting
    period. The amounts reflected in this table may not necessarily be
    achieved. One share of stock purchased in 1996 at $15.94 would yield
    profits of $10.02 per share at 5% appreciation over ten years, or $25.40
    per share at 10% appreciation over the same period. One share of stock
    purchased in 1996 at $21.75 would yield profits of $13.68 per share at 5%
    appreciation over ten years, or $34.66 per share at 10% appreciation over
    the same period. One share of stock purchased in 1996 at $16.75 would
    yield profits of $10.53 per share at 5% appreciation over ten years, or
    $26.70 per share at 10% appreciation over the same period.
 
(2) Generally, options granted under the 1996 Option Plan vest at the rate of
    25% of the options granted for each full year of the optionee's continuous
    employment with the Company and are exercisable to the extent vested. See
    also "--Employment Contracts and Termination of Employment and Change in

  EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT AND CHANGE IN CONTROL
ARRANGEMENTS
 
  Effective March 3, 1992, the Company entered into a two-year employment
agreement with David L. Kalkbrenner which provides for automatic one-year
extensions until the agreement is terminated as described below. The
agreement, as amended, provides for, among other things: (a) a base salary of
$135,000 per year, as adjusted at the discretion of the board of directors;
(b) a discretionary annual bonus based upon the pre-tax net profits of the
Company, (c) payment to Mr. Kalkbrenner of his base salary (reduced by the
amount received by him from state disability insurance or workers'
compensation or other similar insurance through policies provided by the
Company) for a period of six months if he becomes disabled so that he is
unable to perform his duties; (d) four weeks annual vacation leave; (e) a
$500,000 life insurance policy; (f) an automobile allowance; and (g)
reimbursement for ordinary and necessary expenses incurred by Mr. Kalkbrenner
in connection with his employment. The agreement may be terminated with or
without cause, but if the agreement is terminated due to the occurrence of
circumstances that make it impossible or impractical for the Company to
conduct or continue its business, the loss by the Company of its legal
capacity to contract, the Company's breach of the terms of the agreement, or
in the Company's discretion by giving not less than 30 days' prior written
notice of termination, Mr. Kalkbrenner will be entitled to receive severance
compensation equal to 24 months of Mr. Kalkbrenner's then existing base
salary. The agreement further provides that in the event of a "change in
control" as defined therein and within a period of two years following
consummation of such change in control: (a) Mr. Kalkbrenner's employment is
terminated; or (b) any adverse change occurs in the nature and scope of Mr.
Kalkbrenner's position, responsibilities, duties, salary, benefits or location
of employment; or (c) any event occurs which reasonably constitutes a
demotion, significant diminution or constructive termination of
Mr. Kalkbrenner's employment, Mr. Kalkbrenner will be entitled to receive
severance compensation in an amount equal to two and one-half times his
average annual compensation for the five years immediately preceding the
change in control (or for such shorter time as Mr. Kalkbrenner was employed by
the Company).
 
  The Company has entered into an Executive Salary Continuation Agreement with
C. Donald Allen effective as of August 1, 1993. The agreement provides for an
annual benefit of up to $100,000 to be paid to Mr. Allen or his designated
beneficiary over a period of one hundred and eighty (180) months. The benefit
is effective upon: (i) Mr. Allen's attainment of sixty-five (65) years of age
or his death or disability prior to such time if he were
 
                                      61
<PAGE>
 
actively employed by the Company at the time; (ii) termination of his
employment by the Company without "cause" (as defined in the agreement); (iii)
termination or constructive termination of his employment by the Company after
the occurrence of a "change of control" in the Company or the Bank as defined
in the agreement. Although this agreement is intended to provide Mr. Allen with
an additional incentive to remain in the employ of the Company the agreement
states it shall not be deemed to constitute a contract of employment between
Mr. Allen and the Bank nor shall any provision of this agreement restrict the
right of Mr. Allen to terminate his employment. The agreement shall have no
impact or effect upon any separate written employment agreement which Mr. Allen
may have with the Company.
 
  The Company has entered into an Employment Severance and Retirement Benefits
Agreements with Steven C. Smith effective as of September 1, 1994, David R.
Hood, effective as of April 14, 1994 and Hall Palmer effective as of May 1,
1995. Each employment agreement sets the officer's beginning annual salary,
subject to annual cost of living adjustments, with the initial salary payable
to Mr. Smith being set at $135,000 and the initial salary payable to Mr. Hood
and Mr. Palmer being set at $120,000. Each of these employment agreements
entitles the officer to severance benefits equal to 12 months' salary in the
event that such officer's employment is terminated for any reasons other than
death, disability, retirement or certain acts of misconduct, or in the event
that such officer resigns within one year after a change in control of the
Company upon a reduction in responsibilities or compensation or certain other
events deemed to be unfavorable to the officer. In addition, the agreements
entitle each officer to certain retirement benefits. See "--Retirement
Benefits" herein.
 
  1996 STOCK OPTION PLAN
 
  Greater Bay's Board of Directors has adopted the 1996 Option Plan for the
purpose of offering selected employees, directors and consultants an
opportunity to acquire a proprietary interest in the success of Greater Bay, or
to increase such interest, by purchasing shares of Common Stock. The 1996
Option Plan provides both for the grant of nonstatutory options as well as
incentive stock options intended to qualify under Section 422 of the Code.
 
  Options granted under the 1996 Option Plan contain provision pursuant to
which, in the event of a Change in Control (as defined herein) of Greater Bay,
all unexercised options will become exercisable in full prior to such event,
unless the surviving corporation substitutes a substantially equivalent option.
The 1996 Option Plan provides that a "Change of Control" will occur in the
event of (i) a change in the composition of the Board of Directors, as a result
of which fewer than half of the incumbent directors are directors who either
(a) had been directors of Greater Bay (including prior service as a director of
either CNB or MPB) 24 months prior to such change or (b) were elected, or
nominated for election, to the Board of Directors with the affirmative votes of
at least a majority of the directors who had been directors of Greater Bay at
the effective time of the Merger or 24 months prior to such change (whichever
is later) and who were still in office at the time of the election or
nomination or (ii) any "person" (as such term is defined in Sections 13(d) and
14(d) of the Exchange Act) who is or become the beneficial owner, directly or
indirectly, of securities of Greater Bay representing 50% or more of the
combined voting power of Greater Bay's then outstanding securities.
 
  RETIREMENT BENEFITS
 
  Pursuant to the employment agreements between the Company and Messrs. Smith,
Hood and Palmer, each such officer or his spouse (should she survive him) is
entitled to retirement benefits based upon the proceeds of a split-dollar life
insurance policy maintained by the Company for each officer's benefit. Each
officer may begin receiving benefits upon reaching "retirement age" (as defined
in each agreement) or upon termination of employment, whichever occurs later.
Benefits are payable in the form of draws against the annual increase in the
cash surrender value of the officer's insurance policy from the time benefits
commence, up to a maximum annual draw of $55,000 for Mr. Hood, $44,000 for Mr.
Palmer and $60,000 for Mr. Smith (or such lesser amount as shall have vested,
as described below) with the increase in value in excess of such amount
becoming the property of the Company. The right to make such draws continues
during the lifetime of the officer and his surviving spouse, but in no case
longer than 40 years. The right to this retirement benefit vests at 1/84 of
such amount
 
                                       62
<PAGE>
 
monthly following the effective date of such employment agreement, provided
that vesting is subject to acceleration upon the occurrence of certain events
following a Change in Control, as such term is defined in each employment
agreement. See "--Employment Contracts and Termination of Employment and
Change in Control Arrangements" herein.

Directors in 1997 is $189,500.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  The Executive Committee acts as the Executive Compensation Committee of
Greater Bay. The members of the Executive Committee are Messrs. Gatto,
Matteson, Lindsay and van Bronkhorst. None of these persons serves or has
served as an officer or employee of the Company or the Banks. Mr. Matteson has
an interest in a building leased by MPB. See "--Certain Relationships and
Related Transactions" herein.
 
  During 1996, the Executive Committee of Mid-Peninsula served as the
Compensation Committee for Mid-Peninsula and MNB. The members of the Committee
are Messrs. Kalkbrenner, Matteson, Seiler, Thoits and van Bronkhorst. No
person who served as a member of the Executive Committee during 1996 has ever
been an officer or employee of Mid-Peninsula or MPB, except Mr. Kalkbrenner.
 
  During 1996, the Executive Committee of Cupertino served as the Compensation
Committee of Cupertino and CNB. The members of the Committee were Messrs.
Gatto, Lindsay, McLaughlin and Randall. No person who served as a member of
the Executive Committee of Cupertino during 1996 has ever been an officer or
employee of Cupertino or CNB.
 
SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
  Section 16(a) of the Exchange Act requires the Company's executive officers
and directors, and persons who own more than ten percent of a request class of
the Company's equity securities, to file reports of ownership and changes in
ownership with the Commission. Executive offices, directors and greater than
ten-percent shareholders are required by Commission regulation to furnish to
the Company with copies of all Section 16(a) forms they file.
 
                                      63
<PAGE>
 
  Based solely on review of the copies of such forms furnished to the Company,
or written representation that no Form 5 was required, the Company believes
that during the fiscal year ended December 31, 1996 all executive officers,
directors and greater than ten-percent beneficial owners complied with all
Section 16(a) filing requirements applicable to them, except as follows:
Following the consummation of the Merger, a Form 4 reporting the change in
ownership as a result of the consummation of the Merger was filed late for
each of the former directors of Cupertino and executive officers of Cupertino
who became directors and executive officers of Greater Bay after the Merger.
These individuals included Messrs. Allen, Gatto, Hood, Jackson, Lindsay,
McLaughlin, Palmer, Randall and Smith.
 
                CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
  The Company, through the Banks, has had, and expects in the future to have,
banking transactions in the ordinary course of its business with the Company's
directors and officers and their associates, including transactions with
corporations of which such persons are directors, officers or controlling
shareholders, on substantially the same terms (including interest rates and
collateral) as those prevailing for comparable transactions with others.
Management believes that such transactions comprising loans did not involve
more than the normal risk of collectibility or present other unfavorable
features. Loans to executive officers of the Company are subject to
limitations as to amount and purposes prescribed in part by the Federal
Reserve Act, as amended.
 
  MPB leases its offices at 420 Cowper Street, Palo Alto, California 94301
from MPB Associates, a tenant-in-common arrangement in which three directors
of Greater Bay, Messrs. Matteson, Seiler and Thoits, and four other directors
of MPB hold an approximate 51% interest. The acquisition of MPB's leased
premises by MPB Associates in 1990 did not result in a change in the terms of
MPB's lease.
 
  The lease, which originally expired in May 1993, has been extended through
January 2000. MPB pays an annual rental of $560,000 for the entire leased
space. Additionally, MPB pays real property taxes, utilities, and building
insurance, to the extent they exceed, on an annual basis, $1.40 per rentable
square foot, $1.60 per rentable square foot, and $0.17 per rentable square
foot, respectively. The rent will be adjusted every twelve months beginning
June 1, 1997 in accordance with the change in the immediately preceding year
over 1992 in the Consumer Price Index for All Urban Consumers, San
Francisco/Oakland metropolitan Area, All-Items (1967 = 100) as published by
the U.S. Department of Labor, Bureau of Labor Statistics. The lease also
contains a provision granting MPB a right of first refusal to purchase the
building during the term of the lease upon the same terms and conditions that
the landlord is willing to accept from a third party.

                 DESCRIPTION OF THE TRUST PREFERRED SECURITIES
 
  The Trust Preferred Securities and the Common Securities will be issued
pursuant to the terms of the Trust Agreement. The Trust Agreement will be
qualified as an indenture under the Trust Indenture Act. Initially, Wilmington
Trust Company will be the Delaware Trustee and the Property Trustee and will
act as trustee for the purpose of complying with the Trust Indenture Act. The
terms of the Trust Preferred Securities will include those stated in the Trust
Agreement and those made part of the Trust Agreement by the Trust Indenture
Act. This summary of certain terms and provisions of the Trust Preferred
Securities and the Trust Agreement does not purport to be complete and is
subject to, and is qualified in its entirety by reference to, all the
provisions of the Trust Agreement, including the definitions therein of
certain terms, and the Trust Indenture Act. Wherever particular defined terms
of the Trust Agreement (as amended or supplemented from time to time) are
referred to herein, such defined terms are incorporated herein. The form of
the Trust Agreement has been filed as an exhibit to the Registration Statement
of which this Prospectus forms a part.
 
GENERAL
 
  Pursuant to the terms of the Trust Agreement, the Administrative Trustees on
behalf of GBB Capital will issue the Trust Preferred Securities and the Common
Securities (collectively, the "Trust Securities"). The Trust Preferred
Securities will represent preferred undivided beneficial interests in the
assets of GBB Capital and the holders thereof will be entitled to a preference
in certain circumstances with respect to Distributions and amounts payable on
redemption or liquidation over the Common Securities of GBB Capital (which
will be held by Greater Bay), as well as other benefits as described in the
Trust Agreement.
 
 
                                      66
<PAGE>
 
  The Trust Preferred Securities will represent undivided beneficial ownership
interests in GBB Capital and the holders thereof will be entitled to a
preference in certain circumstances with respect to Distributions and amounts
payable on redemption or liquidation over Common Securities, as well as other
benefits enumerated in the Guarantee Agreement. The Trust Preferred Securities
will rank pari passu, and payments will be made thereon pro rata, with the
Common Securities of GBB Capital except as described under "Subordination of
Common Securities of GBB Capital Held by Greater Bay" below.
 
  Legal title to the Junior Subordinated Debentures will be held by the
Property Trustee in trust for the benefit of the holders of the Trust
Securities. The Guarantee executed by Greater Bay for the benefit of the
holders of the Trust Preferred Securities (the "Guarantee") will be a
guarantee on a subordinated basis and will not guarantee payment of
Distributions or amounts payable on redemption of the Trust Preferred
Securities or on liquidation of the Trust Preferred Securities if GBB Capital
does not have funds on hand available to make such payments. See "Description
of Guarantee."
 
DISTRIBUTIONS
 
  Payment of Distributions. Distributions on the Trust Preferred Securities
will be payable at the annual rate of   % of the stated Liquidation Amount of
$25, payable quarterly in arrears on the 15th day of March, June, September
and December in each year, commencing June 15, 1997 to the holders of the
Trust Preferred Securities on the relevant record dates (each date on which
Distributions are payable in accordance with the foregoing, a "Distribution
Date"). The amount of each Distribution due with respect to the Trust
Preferred Securities will include amounts accrued through the date the
Distribution payment is due. Distributions on the Trust Preferred Securities
will be payable to the holders thereof as they appear on the register of GBB
Capital on the relevant record date which, for so long as the Trust Preferred
Securities remain in book-entry form, will be one Business Day (as defined
below) prior to the relevant Distribution Date and, in the event the Trust
Preferred Securities are not in book-entry form, will be the first day of the
month in which the relevant Distribution Date occurs. Distributions will
accumulate from the date of original issuance. The first Distribution Date for
the Trust Preferred Securities will be June 15, 1997.
 
  The amount of Distributions payable for any period will be computed on the
basis of a 360-day year of twelve 30-day months. In the event that any date on
which Distributions are payable on the Trust Preferred Securities is not a
Business Day, payment of the Distribution payable on such date will be made on
the next Business Day (and without any interest or other payment in respect to
any such delay) except that, if such Business Day is in the next succeeding
calendar year, payment of such Distribution shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on the date such payment was originally payable. As used in this Prospectus, a
"Business Day" shall mean any day other than a Saturday or a Sunday, or a day
on which banking institutions in the State of California are authorized or
required by law or executive order to remain closed or a day on which the
corporate trust office of the Property Trustee or the Indenture Trustee is
closed for business.
 
  The funds of GBB Capital available for distribution to holders of its Trust
Preferred Securities will be limited to payments by Greater Bay under the
Junior Subordinated Debentures in which GBB Capital will invest the proceeds
from the issuance and sale of its Trust Preferred Securities. See "Description
of Junior Subordinated Debentures." If Greater Bay does not make interest
payments on the Junior Subordinated Debentures, the Property Trustee will not
have funds available to pay Distributions on the Trust Preferred Securities.
The payment of Distributions (if and to the extent GBB Capital has funds
legally available for the payment of such Distributions and cash sufficient to
make such payments) is guaranteed by Greater Bay. See "Description of
Guarantee."
 
  Extension Period. So long as no Debenture Event of Default has occurred and
is continuing, Greater Bay has the right under the Indenture to defer the
payment of interest on the Junior Subordinated Debentures at any time or from
time to time for a period not exceeding 20 consecutive quarters with respect
to each such period (each, an "Extension Period"), provided that no Extension
Period may extend beyond the Stated Maturity of the
 
                                      67
<PAGE>
 
Junior Subordinated Debentures. As a consequence of any such election,
quarterly Distributions on the Trust Preferred Securities will be deferred by
GBB Capital during any such Extension Period. Distributions to which holders
of Trust Preferred Securities are entitled will accumulate additional amounts
thereon at the rate per annum of   % thereof, compounded quarterly from the
relevant Distribution Date, to the extent permitted under applicable law. The
term "Distributions" as used herein shall include any such additional
accumulated amounts. During any such Extension Period, Greater Bay may not (i)
declare or pay any dividends or distributions on, or redeem, purchase,
acquire, or make a liquidation payment with respect to, any of Greater Bay's
capital stock (which includes common and preferred stock) or (ii) make any
payment of principal, interest or premium, if any, on or repay, repurchase or
redeem any debt securities of Greater Bay that rank pari passu with or junior
in interest to the Junior Subordinated Debentures or make any guarantee
payments with respect to any guarantee by Greater Bay of the debt securities
of any subsidiary of Greater Bay if such guarantee ranks pari passu with or
junior in interest to the Junior Subordinated Debentures (other than (a)
dividends or distributions in common stock of Greater Bay, (b) any declaration
of a dividend in connection with the implementation of a stockholders' rights
plan, or the issuance of stock under any such plan in the future, or the
redemption or repurchase of any such rights pursuant thereto, (c) payments
under the Guarantee and (d) purchases of common stock for issuance of common
stock or rights under any of Greater Bay's benefit plans for its directors,
officers or employees) as consideration in an acquisition transaction. Prior
to the termination of any such Extension Period, Greater Bay may further
extend such Extension Period, provided that such extension does not cause such
Extension Period to exceed 20 consecutive quarters or extend beyond the Stated
Maturity. Upon the termination of any such Extension Period and the payment of
all amounts then due, and subject to the foregoing limitations, Greater Bay
may elect to begin a new Extension Period. Subject to the foregoing, there is
no limitation on the number of times that Greater Bay may elect to begin an
Extension Period. Greater Bay has no current intention of exercising its right
to defer payments of interest by extending the interest payment period on the
Junior Subordinated Debentures.
 
REDEMPTION
 
  Mandatory Redemption. Upon the repayment or redemption at any time, in whole
or in part, of any Junior Subordinated Debentures, the proceeds from such
repayment or redemption shall be applied by the Property Trustee to redeem a
Like Amount (as defined below) of the Trust Securities, upon not less than 30
nor more than 60 days' notice of a date of redemption (the "Redemption Date"),
at the Redemption Price (as defined below). See "Description of Junior
Subordinated Debentures--Redemption." If less than all of the Junior
Subordinated Debentures are to be repaid or redeemed on a Redemption Date,
then the proceeds from such repayment or redemption shall be allocated to the
redemption of the Trust Securities pro rata. The amount of premium, if any,
paid by Greater Bay upon the redemption of all or any part of the Junior
Subordinated Debentures to be repaid or redeemed on a Redemption Date shall be
allocated to the redemption pro rata of the Trust Securities.
 
  Optional Redemption. Greater Bay will have the right to redeem the Junior
Subordinated Debentures (i) on or after        , 2002, in whole at any time or
in part from time to time at a redemption price equal to the accrued and
unpaid interest on the Junior Subordinated Debentures so redeemed to the date
fixed for redemption, plus 100% of the principal amount thereof, or (ii) at
any time, in whole (but not in part), upon the occurrence of a Tax Event, an
Investment Company Event or a Capital Treatment Event at a redemption price
equal to the accrued and unpaid interest on the Junior Subordinated Debentures
so redeemed to the date fixed for redemption, plus 100% of the principal
amount thereof, in each case subject to receipt of prior approval by the
Federal Reserve if then required under applicable capital guidelines or
policies of the Federal Reserve. See "Description of Junior Subordinated
Debentures--Redemption."
 
  Tax Event Redemption, Investment Company Event Redemption, Capital Treatment
Event Redemption or Distribution of Junior Subordinated Debentures. If a Tax
Event, an Investment Company Event or a Capital Treatment Event shall occur
and be continuing, Greater Bay has the right to redeem the Junior Subordinated
Debentures in whole (but not in part) and thereby cause a mandatory redemption
of the Trust Securities in whole
 
                                      68
<PAGE>
 
(but not in part) at the Redemption Price (as defined below) within 90 days
following the occurrence of such Tax Event, Investment Company Event or
Capital Treatment Event, in each case subject to receipt of prior approval by
the Federal Reserve if then required under applicable capital guidelines or
policies of the Federal Reserve. In the event a Tax Event, an Investment
Company Event or Capital Treatment Event has occurred and is continuing and
Greater Bay does not elect to redeem the Junior Subordinated Debentures and
thereby cause a mandatory redemption of the Trust Securities or to liquidate
GBB Capital and cause the Junior Subordinated Debentures to be distributed to
holders of the Trust Securities in liquidation of GBB Capital as described
below, such Trust Securities will remain outstanding and Additional Sums (as
defined below) may be payable on the Junior Subordinated Debentures.
 
  DEFINITIONS
 
  "Additional Sums" means the additional amounts as may be necessary to be
paid by Greater Bay with respect to the Junior Subordinated Debentures in
order that the amount of Distributions then due and payable by GBB Capital on
the outstanding Trust Securities of GBB Capital shall not be reduced as a
result of any additional taxes, duties and other governmental charges to which
GBB Capital has become subject as a result of a Tax Event.
 
  "Like Amount" means (i) with respect to a redemption of Trust Securities,
Trust Securities having a Liquidation Amount (as defined below) equal to that
portion of the principal amount of Junior Subordinated Debentures to be
contemporaneously redeemed in accordance with the Indenture, allocated to the
Common Securities and to the Trust Preferred Securities based upon the
relative Liquidation Amounts of such classes and the proceeds of which will be
used to pay the Redemption Price of such Trust Securities, and (ii) with
respect to a distribution of Junior Subordinated Debentures to holders of
Trust Securities in connection with a dissolution or liquidation of GBB
Capital, Junior Subordinated Debentures having a principal amount equal to the
Liquidation Amount of the Trust Securities of the holder to whom such Junior
Subordinated Debentures are distributed.
 
  "Liquidation Amount" means the stated amount of $25 per Trust Security.
 
  "Redemption Price" means, with respect to any Trust Security, the
Liquidation Amount of such Trust Security, plus accumulated and unpaid
Distributions to the Redemption Date, allocated on a pro rata basis (based on
Liquidation Amounts) among the Trust Securities.
 
DISTRIBUTION OF JUNIOR SUBORDINATED DEBENTURES
 
  Subject to Greater Bay and GBB Capital having received an opinion of counsel
to the effect that such distribution will not be a taxable event to the
holders of the Trust Preferred Securities and prior approval of the Federal
Reserve if so required under applicable capital guidelines or policies of the
Federal Reserve, Greater Bay will have the right at any time to liquidate GBB
Capital and, after satisfaction of the liabilities of creditors of GBB Capital
as provided by applicable law, cause the Junior Subordinated Debentures to be
distributed to the holders of Trust Securities in liquidation of GBB Capital.
After the liquidation date fixed for any distribution of Junior Subordinated
Debentures for Trust Preferred Securities (i) such Trust Preferred Securities
will no longer be deemed to be outstanding, (ii) the Depositary or its
nominee, as the record holder of the Trust Preferred Securities, will receive
a registered global certificate or certificates representing the Junior
Subordinated Debentures to be delivered upon such distribution and (iii) any
certificates representing Trust Preferred Securities not held by the
Depositary or its nominee will be deemed to represent the Junior Subordinated
Debentures having a principal amount equal to the Liquidation Amount of such
Trust Preferred Securities, and bearing accrued and unpaid interest in an
amount equal to the accrued and unpaid Distributions on the Trust Preferred
Securities until such certificates are presented to the Administrative
Trustees or their agent for transfer or reissuance.
 
  There can be no assurance as to the market prices for the Trust Preferred
Securities or the Junior Subordinated Debentures that may be distributed in
exchange for the Trust Preferred Securities if a dissolution
 
                                      69
<PAGE>
 
and liquidation of GBB Capital were to occur. Accordingly, the Trust Preferred
Securities that an investor may purchase, or the Junior Subordinated
Debentures that the investor may receive on dissolution and liquidation of GBB
Capital, may trade at a discount to the price that the investor paid to
purchase the Trust Preferred Securities offered hereby.
 
REDEMPTION PROCEDURES
 
  Trust Preferred Securities redeemed on each Redemption Date shall be
redeemed at the Redemption Price with the applicable proceeds from the
contemporaneous redemption of the Junior Subordinated Debentures. Redemptions
of the Trust Preferred Securities shall be made and the Redemption Price shall
be payable on each Redemption Date only to the extent that GBB Capital has
funds on hand available for the payment of such Redemption Price. See "--
Subordination of Common Securities of GBB Capital Held by Greater Bay" herein
and "Description of Guarantee."
 
  If GBB Capital gives a notice of redemption in respect of the Trust
Preferred Securities, then, by 12:00 noon, California time on the Redemption
Date, to the extent funds are available, the Property Trustee will deposit
with the Depositary funds sufficient to pay the aggregate Redemption Price and
will give the Depositary irrevocable instructions and authority to pay the
Redemption Price to the holders of such Trust Preferred Securities. See "Book-
Entry Issuance." If such Trust Preferred Securities are no longer in book-
entry form, the Property Trustee, to the extent funds are available, will
deposit with the paying agent for such Trust Preferred Securities funds
sufficient to pay the aggregate Redemption Price and will give such paying
agent irrevocable instructions and authority to pay the Redemption Price to
the holders thereof upon surrender of their certificates evidencing such Trust
Preferred Securities. Notwithstanding the foregoing, Distributions payable on
or prior to the Redemption Date shall be payable to the holders of such Trust
Preferred Securities on the relevant record dates for the related Distribution
Dates. If notice of redemption shall have been given and funds deposited as
required, then upon the date of such deposit, all rights of the holders of the
Trust Preferred Securities will cease, except the right of the holders of the
Trust Preferred Securities to receive the applicable Redemption Price, but
without interest on such Redemption Price, and such Trust Preferred Securities
will cease to be outstanding. In the event that any date fixed for redemption
of such Trust Preferred Securities is not a Business Day, then payment of the
Redemption Price payable on such date will be made on the next succeeding
Business Day (and without any interest or other payment in respect of any such
delay), except that, if such Business Day falls in the next calendar year,
such payment will be made on the immediately preceding Business Day. In the
event that payment of the Redemption Price in respect of Trust Preferred
Securities called for redemption is improperly withheld or refused and not
paid either by GBB Capital or by Greater Bay pursuant to the Guarantee,
Distributions on such Trust Preferred Securities will continue to accrue at
the then applicable rate, from the Redemption Date originally established by
GBB Capital for such Trust Preferred Securities to the date such Redemption
Price is actually paid, in which case the actual payment date will be the date
fixed for redemption for purposes of calculating the Redemption Price. See
"Description of Guarantee."
 
  Subject to applicable law (including, without limitation, United States
federal securities law), Greater Bay may at any time and from time to time
purchase outstanding Trust Preferred Securities by tender, in the open market
or by private agreement.
 
  Payment of the Redemption Price on the Trust Preferred Securities and any
distribution of Junior Subordinated Debentures to holders of Trust Preferred
Securities shall be made to the applicable recordholders thereof as they
appear on the register of such Trust Preferred Securities on the relevant
record date, which date shall be one Business Day prior to the relevant
Redemption Date or Liquidation Date, as applicable; provided, however, that in
the event that any Trust Preferred Securities are not in book-entry form, the
relevant record date for such Trust Preferred Securities shall be a date at
least 15 days prior to the Redemption Date or Liquidation Date, as applicable.
In the case of a liquidation, the record date shall be no more than 45 days
before the Liquidation Date.
 
  If less than all of the Trust Securities issued by GBB Capital are to be
redeemed on a Redemption Date, then the aggregate Redemption Price for such
Trust Securities to be redeemed shall be allocated pro rata to the
 
                                      70
<PAGE>
 
Trust Preferred Securities and Common Securities based upon the relative
Liquidation Amounts of such classes. The particular Trust Preferred Securities
to be redeemed shall be selected by the Property Trustee from the outstanding
Trust Preferred Securities not previously called for redemption, by such
method as the Property Trustee shall deem fair and appropriate and which may
provide for the selection for redemption of portions (equal to $25 or an
integral multiple thereof) of the Liquidation Amount of Trust Preferred
Securities. The Property Trustee shall promptly notify the Security registrar
in writing of the Trust Preferred Securities selected for redemption and, in
the case of any Trust Preferred Securities selected for partial redemption,
the Liquidation Amount thereof to be redeemed. For all purposes of the Trust
Agreement, unless the context otherwise requires, all provisions relating to
the redemption of Trust Preferred Securities shall relate to the portion of
the aggregate Liquidation Amount of Trust Preferred Securities which has been
or is to be redeemed.
 
  Notice of any redemption will be mailed at least 30 days but not more than
60 days before the Redemption Date to each holder of Trust Securities at such
holder's registered address. Unless GBB Capital defaults in payment of the
applicable Redemption Price, on and after the Redemption Date, Distributions
will cease to accrue on such Trust Preferred Securities called for redemption.
 
SUBORDINATION OF COMMON SECURITIES OF GBB CAPITAL HELD BY GREATER BAY
 
  Payment of Distributions on, and the Redemption Price of, the Trust
Preferred Securities and Common Securities, as applicable, shall be made pro
rata based on the Liquidation Amounts of the Trust Preferred Securities and
Common Securities; provided, however, that if on any Distribution Date or
Redemption Date a Debenture Event of Default shall have occurred and be
continuing, no payment of any Distribution on, or applicable Redemption Price
of, any of the Common Securities, and no other payment on account of the
redemption, liquidation or other acquisition of the Common Securities, shall
be made unless payment in full in cash of all accumulated and unpaid
Distributions on all of the outstanding Trust Preferred Securities for all
Distribution periods terminating on or prior thereto, or in the case of
payment of the applicable Redemption Price the full amount of such Redemption
Price on all of the outstanding Trust Preferred Securities then called for
redemption, shall have been made or provided for, and all funds available to
the Property Trustee shall first be applied to the payment in full in cash of
all Distributions on, or Redemption Price of, the Trust Preferred Securities
then due and payable.
 
  In the case of any Event of Default under the Trust Agreement resulting from
a Debenture Event of Default, Greater Bay as holder of the Common Securities
will be deemed to have waived any right to act with respect to any such Event
of Default until the effect of all such Events of Default have been cured,
waived or otherwise eliminated. Until any such Events of Default have been so
cured, waived or otherwise eliminated, the Property Trustee shall act solely
on behalf of the holders of the Trust Preferred Securities and not on behalf
of Greater Bay as holder of the Common Securities, and only the holders of the
Trust Preferred Securities will have the right to direct the Property Trustee
to act on their behalf.
 
LIQUIDATION DISTRIBUTION UPON TERMINATION
 
  Greater Bay will have the right at any time to terminate GBB Capital and
cause the Junior Subordinated Debentures to be distributed to the holders of
the Trust Preferred Securities. Such right is subject to Greater Bay having
received prior approval of the Federal Reserve if then required under
applicable capital guidelines or policies of the Federal Reserve. See "--
Distribution of Junior Subordinated Debentures" below.
 
  In addition, pursuant to the Trust Agreement, GBB Capital shall
automatically terminate upon expiration of its term and shall earlier
terminate on the first to occur of: (i) certain events of bankruptcy,
dissolution or liquidation of Greater Bay; (ii) the distribution of a Like
Amount of the Junior Subordinated Debentures to the holder of its Trust
Securities, if Greater Bay, as Depositor, has delivered written direction to
the Property Trustee to terminate GBB Capital (which direction is optional
and, except as described above, wholly within the discretion of Greater Bay,
as Depositor); (iii) redemption of all of the Trust Preferred Securities as
described under "-- Redemption--Mandatory Redemption;" (iv) expiration of the
term of GBB Capital; and (v) the entry of an order for the dissolution of GBB
Capital by a court of competent jurisdiction.
 
                                      71
<PAGE>
 
  If an early termination occurs as described in clause (i), (ii), (iv) or (v)
above, GBB Capital shall be liquidated by the Trustees as expeditiously as the
Trustees determine to be possible by distributing, after satisfaction of
liabilities to creditors of GBB Capital as provided by applicable law, to the
holders of such Trust Securities a Like Amount of the Junior Subordinated
Debentures, unless such distribution is determined by the Property Trustee not
to be practical, in which event such holders will be entitled to receive out
of the assets of GBB Capital available for distribution to holders, after
satisfaction of liabilities to creditors of GBB Capital as provided by
applicable law, an amount equal to, in the case of holders of Trust Preferred
Securities, the aggregate of the Liquidation Amount plus accrued and unpaid
Distributions thereon to the date of payment (such amount being the
"Liquidation Distribution"). If such Liquidation Distribution can be paid only
in part because GBB Capital has insufficient assets available to pay in full
the aggregate Liquidation Distribution, then the amounts payable directly by
GBB Capital on the Trust Preferred Securities shall be paid on a pro rata
basis. The holder(s) of the Common Securities will be entitled to receive
distributions upon any such liquidation pro rata with the holders of the Trust
Preferred Securities, except that if a Debenture Event of Default has occurred
and is continuing, the Trust Preferred Securities shall have a priority over
the Common Securities.
 
  Under current United States federal income tax law and interpretations and
assuming, as expected, GBB Capital is treated as a grantor trust, a
distribution of the Junior Subordinated Debentures should not be a taxable
event to holders of the Trust Preferred Securities. Should there be a change
in law, a change in legal interpretation, a Tax Event or other circumstances,
however, the distribution could be a taxable event to holders of the Trust
Preferred Securities. See "Certain Federal Income Tax Consequences." If
Greater Bay elects neither to redeem the Junior Subordinated Debentures prior
to maturity nor to liquidate GBB Capital and distribute the Junior
Subordinated Debentures to holders of the Trust Preferred Securities, the
Trust Preferred Securities will remain outstanding until the repayment of the
Junior Subordinated Debentures.
 
  If Greater Bay elects to liquidate GBB Capital and thereby causes the Junior
Subordinated Debentures to be distributed to holders of the Trust Preferred
Securities in liquidation of GBB Capital, Greater Bay shall continue to have
the right to shorten the maturity of such Junior Subordinated Debentures,
subject to certain conditions. See "Description of Junior Subordinated
Debentures--General."
 
EVENTS OF DEFAULT; NOTICE
 
  Any one of the following events that has occurred and is continuing
constitutes an "Event of Default" under the Trust Agreement (an "Event of
Default") with respect to the Trust Preferred Securities (whatever the reason
for such Event of Default and whether it shall be voluntary or involuntary or
be effected by operation of law or pursuant to any judgment, decree or order
of any court or any order, rule or regulation of any administrative or
governmental body):
 
    (i) the occurrence of a Debenture Event of Default (see "Description of
  Junior Subordinated Debentures--Debenture Events of Default"); or
 
    (ii) default by the Property Trustee in the payment of any Distribution
  when it becomes due and payable, and continuation of such default for a
  period of 30 days; or
 
    (iii) default by the Property Trustee in the payment of any Redemption
  Price of any Trust Security when it becomes due and payable; or
 
    (iv) default in the performance, or breach, in any material respect, of
  any covenant or warranty of the Trustees in the Trust Agreement (other than
  a default or breach in the performance of a covenant or warranty which is
  addressed in clause (ii) or (iii) above), and continuation of such default
  or breach, for a period of 60 days after there has been given, by
  registered or certified mail, to the defaulting Issuer Trustee or Trustees
  by the holders of at least 25% in aggregate Liquidation Amount of the
  outstanding Trust Preferred Securities, a written notice specifying such
  default or breach and requiring it to be remedied and stating that such
  notice is a "Notice of Default" under the Trust Agreement; or
 
    (v) the occurrence of certain events of bankruptcy or insolvency with
  respect to the Property Trustee and the failure by Greater Bay to appoint a
  successor Property Trustee within 60 days thereof.
 
                                      72
<PAGE>
 
  Within five Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee shall transmit
notice of such Event of Default to the holders of the Trust Preferred
Securities, the Administrative Trustees and Greater Bay, as Depositor, unless
such Event of Default shall have been cured or waived. Greater Bay as
Depositor, and the Administrative Trustees are required to file annually with
the Property Trustee a certificate as to whether or not they are in compliance
with all the conditions and covenants applicable to them under the Trust
Agreement.
 
  If a Debenture Event of Default has occurred and is continuing, the Trust
Preferred Securities shall have a preference over the Common Securities upon
termination of GBB Capital as described above. See "--Liquidation Distribution
upon Termination" herein. Upon a Debenture Event of Default, unless the
principal of all the Junior Subordinated Debentures has already become due and
payable, either the Property Trustee or the holders of not less than 25% in
aggregate principal amount of the Junior Subordinated Debentures then
outstanding may declare all of the Junior Subordinated Debentures to be due
and payable immediately by giving notice in writing to Greater Bay (and to the
Property Trustee, if notice is given by holders of the Junior Subordinated
Debentures). If the Property Trustee or the holders of the Junior Subordinated
Debentures fail to declare the principal of all of the Junior Subordinated
Debentures due and payable upon a Debenture Event of Default, the holders of
at least 25% in Liquidation Amount of the Trust Preferred Securities then
outstanding shall have the right to declare the Junior Subordinated Debentures
immediately due and payable. In either event, payment of principal and
interest on the Junior Subordinated Debentures shall remain subordinated to
the extent provided in the Indenture. In addition, holders of the Trust
Preferred Securities have the right in certain circumstances to bring a Direct
Action (as hereinafter defined). See "Description of Junior Subordinated
Debentures--Enforcement of Certain Rights by Holders of Trust Preferred
Securities."
 
REMOVAL OF TRUSTEES
 
  Unless a Debenture Event of Default shall have occurred and be continuing,
any of the Property Trustee, the Depositary Trustee or the Administrative
Trustees may be removed at any time by the holder of the Common Securities. If
a Debenture Event of Default has occurred and is continuing, the Property
Trustee and the Delaware Trustee may be removed at such time by the holders of
a majority in Liquidation Amount of the outstanding Trust Preferred
Securities. In no event will the holders of the Trust Preferred Securities
have the right to vote to appoint, remove or replace the Administrative
Trustees, which voting rights are vested exclusively in Greater Bay as the
holder of the Common Securities. No resignation or removal of a Trustee and no
appointment of a successor trustee shall be effective until the acceptance of
appointment by the successor trustee in accordance with the provisions of the
Trust Agreement.
 
CO-TRUSTEES AND SEPARATE PROPERTY TRUSTEE
 
  Unless an Event of Default shall have occurred and be continuing, at any
time or times, for the purpose of meeting the legal requirements of the Trust
Indenture Act or of any jurisdiction in which any part of Trust Property may
at the time be located, Greater Bay, as the holder of the Common Securities,
and the Administrative Trustees shall have power to appoint one or more
persons either to act as a co-trustee, jointly with the Property Trustee, of
all or any part of such Trust Property, or to act as separate trustee of any
such property, in either case with such powers as may be provided in the
instrument of appointment, and to vest in such person or persons in such
capacity any property, title, right or power deemed necessary or desirable,
subject to the provisions of the Trust Agreement. In case a Debenture Event of
Default has occurred and is continuing, the Property Trustee alone shall have
power to make such appointment.
 
MERGER OR CONSOLIDATION OF TRUSTEES
 
  Any Person (as defined in the Trust Agreement) into which the Property
Trustee, the Delaware Trustee or any Administrative Trustee that is not a
natural person may be merged or converted or with which it may be
consolidated, or any Person resulting from any merger, conversion or
consolidation to which such Issuer Trustee shall be a party, or any person
succeeding to all or substantially all the corporate trust business of such
Issuer Trustee, shall be the successor of such Issuer Trustee under the Trust
Agreement, provided such corporation shall be otherwise qualified and
eligible.

MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF GBB CAPITAL
 
  GBB Capital may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other Person, except as
described below. GBB Capital may, at the request of Greater Bay, with the
consent of the Administrative Trustees and without the consent of the holders
of the Trust Preferred Securities, merge with or into, consolidate,
amalgamate, or be replaced by or convey, transfer or lease its properties and
assets substantially as an entirety to a trust organized as such under the
laws of any State; provided, that (i) such successor entity either (a)
expressly assumes all of the obligations of GBB Capital with respect to the
Trust Preferred Securities or (b) substitutes for the Trust Preferred
Securities other securities having substantially the same terms as the Trust
Preferred Securities (the "Successor Securities") so long as the Successor
Securities rank the same as the Trust Preferred Securities rank in priority
with respect to distributions and payments upon liquidation, redemption and
otherwise, (ii) Greater Bay expressly appoints a trustee of such successor
entity possessing the same powers and duties as the Property Trustee as the
holder of the Junior Subordinated Debentures, (iii) the Successor Securities
are listed, or any Successor Securities will be listed upon notification of
issuance, on any national securities exchange or other organization on which
the Trust Preferred Securities are then listed, if any, (iv) such merger,
consolidation, amalgamation, conveyance, transfer or lease does not cause the
Trust Preferred Securities to be downgraded by any nationally recognized
statistical rating organization which gives ratings to the Trust Preferred
Securities; (v) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not adversely affect the rights,
preferences and privileges of the holders of the Trust Preferred Securities
(including any Successor Securities) in any material respect, (vi) such
successor entity has a purpose identical to that of GBB Capital, (vii) the
Successor Securities will be listed or traded on any national securities
exchange or other organization on which the Trust Preferred Securities may
then be listed, (viii) prior to such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease, Greater Bay has received an
opinion from independent counsel to GBB Capital experienced in such matters to
the effect that (a) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not adversely affect the rights,
preferences and privileges of the holders of the Trust Preferred Securities
(including any Successor Securities) in any material respect, and (b)
following such merger, consolidation, amalgamation, replacement, conveyance,
transfer or lease, neither GBB Capital nor such successor entity will be
required to register as an investment company under the Investment Company Act
and (ix) Greater Bay or any permitted successor or designee owns all of the
common securities of such successor entity and guarantees the obligations of
such successor entity under the Successor Securities at least to the extent
provided by the Guarantee. Notwithstanding the foregoing, GBB Capital shall
not, except with the consent of holders of 100% in Liquidation Amount of the
Trust Preferred Securities, consolidate, amalgamate, merge with or into, or be
replaced by or convey, transfer or lease its properties and assets
substantially as an entirety to any other entity or permit any other entity to
consolidate, amalgamate, merge with or into, or replace it if such
consolidation, amalgamation, merger, replacement, conveyance, transfer or
lease would cause GBB Capital or the successor entity to be classified as
other than a grantor trust for United States federal income tax purposes.
 
VOTING RIGHTS; AMENDMENT OF THE TRUST AGREEMENT
 
  Except as provided below and under "Description of Guarantee--Amendments and
Assignment" and as otherwise required by law and the Trust Agreement, the
holders of the Trust Preferred Securities will have no voting rights.
 
  The Trust Agreement may be amended from time to time by Greater Bay, the
Property Trustee and the Administrative Trustees, without the consent of the
holders of the Trust Securities, (i) to cure any ambiguity, correct or
supplement any provisions in the Trust Agreement that may be inconsistent with
any other provision, or to make any other provisions with respect to matters
or questions arising under the Trust Agreement, which shall not be
inconsistent with the other provisions of the Trust Agreement, or (ii) to
modify, eliminate or add to any provisions of the Trust Agreement to such
extent as shall be necessary to ensure that GBB Capital will be classified for
United States federal income tax purposes as a grantor trust at all times that
any Trust Securities are outstanding or to ensure that GBB Capital will not be
required to register as an "investment company" under
 
                                      74
<PAGE>
 
the Investment Company Act; provided, however, that in the case of clause (i),
such action shall not adversely affect in any material respect the interests
of any holder of Trust Securities, and any amendments of the Trust Agreement
shall become effective when notice thereof is given to the holders of the
Trust Securities. The Trust Agreement may be amended by the Issuer Trustees
and the Company with (i) the consent of holders representing not less than a
majority of the aggregate Liquidation Amount of the outstanding Trust
Securities, and (ii) receipt by the Issuer Trustees of an opinion of counsel
to the effect that such amendment or the exercise of any power granted to the
Issuer Trustees in accordance with such amendment will not affect GBB
Capital's status as a grantor trust for United States federal income tax
purposes or GBB Capital's exemption from status as an "investment company"
under the Investment Company Act, provided that without the consent of each
holder of Trust Securities, the Trust Agreement may not be amended to (i)
change the amount or timing of any Distribution on the Trust Securities or
otherwise adversely affect the amount of any Distribution required to be made
in respect of the Trust Securities as of a specified date or (ii) restrict the
right of a holder of Trust Securities to institute suit for the enforcement of
any such payment on or after such date.
 
  So long as any Junior Subordinated Debentures are held by the Property
Trustee, the Issuer Trustees shall not (i) direct the time, method and place
of conducting any proceeding for any remedy available to the Indenture
Trustee, or executing any trust or power conferred on the Property Trustee
with respect to the Junior Subordinated Debentures, (ii) waive any past
default that is waivable under the Indenture, (iii) exercise any right to
rescind or annul a declaration that the principal of all the Junior
Subordinated Debentures shall be due and payable or (iv) consent to any
amendment, modification or termination of the Indenture or the Junior
Subordinated Debentures, where such consent shall be required, without, in
each case, obtaining the prior approval of the holders of a majority in
aggregate Liquidation Amount of all outstanding the Trust Preferred
Securities; provided, however, that where a consent under the Indenture would
require the consent of each holder of Junior Subordinated Debentures affected
thereby, no such consent shall be given by the Property Trustee without the
prior consent of each holder of the Trust Preferred Securities. The Issuer
Trustees shall not revoke any action previously authorized or approved by a
vote of the holders of the Trust Preferred Securities except by subsequent
vote of the holders of the Trust Preferred Securities. The Property Trustee
shall notify each holder of the Trust Preferred Securities of any notice of
default with respect to the Junior Subordinated Debentures. In addition to
obtaining the foregoing approvals of such holders of the Trust Preferred
Securities, prior to taking any of the foregoing actions, the Issuer Trustees
shall obtain an opinion of counsel experienced in such matters to the effect
that GBB Capital will not be classified as other than a grantor trust for
United States federal income tax purposes.
 
  Any required approval of holders of the Trust Preferred Securities may be
given at a meeting of holders of Trust Preferred Securities convened for such
purpose or pursuant to written consent. The Property Trustee will cause a
notice of any meeting at which holders of the Trust Preferred Securities are
entitled to vote, or of any matter upon which action by written consent of
such holders is to be taken, to be given to each holder of record of the Trust
Preferred Securities in the manner set forth in the Trust Agreement.
 
  No vote or consent of the holders of the Trust Preferred Securities will be
required for GBB Capital to redeem and cancel the Trust Preferred Securities
in accordance with the Trust Agreement.
 
  Notwithstanding that holders of the Trust Preferred Securities are entitled
to vote or consent under any of the circumstances described above, any of the
Trust Preferred Securities that are owned by Greater Bay, the Trustees or any
affiliate of Greater Bay or any Trustees, shall, for purposes of such vote or
consent, be treated as if they were not outstanding.
 
GLOBAL TRUST PREFERRED SECURITIES
 
  The Trust Preferred Securities will be represented by one or more global
certificates registered in the name of the Depositary or its nominee ("Global
Trust Preferred Security"). Beneficial interests in the Trust Preferred
Securities will be shown on, and transfers thereof will be effected only
through, records maintained by
 
                                      75
<PAGE>
 
participants in the Depositary. Except as described below, Trust Preferred
Securities in certificated form will not be issued in exchange for the global
certificates. See "Book-Entry Issuance."
 
  A global security shall be exchangeable for Trust Preferred Securities
registered in the names of persons other than the Depositary or its nominee
only if (i) the Depositary notifies Greater Bay that it is unwilling or unable
to continue as a depositary for such global security and no successor
depositary shall have been appointed, or if at any time the Depositary ceases
to be a clearing agency registered under the Exchange Act, at a time when the
Depositary is required to be so registered to act as such depositary, (ii)
Greater Bay in its sole discretion determines that such global security shall
be so exchangeable, or (iii) there shall have occurred and be continuing an
Event of Default under the Indenture. Any global security that is exchangeable
pursuant to the preceding sentence shall be exchangeable for definitive
certificates registered in such names as the Depositary shall direct. It is
expected that such instructions will be based upon directions received by the
Depositary with respect to ownership of beneficial interests in such global
security. In the event that Trust Preferred Securities are issued in
definitive form, such Trust Preferred Securities will be in denominations of
$25 and integral multiples thereof and may be transferred or exchanged at the
offices described below.
 
  Unless and until it is exchanged in whole or in part for the individual
Trust Preferred Securities represented thereby, a Global Trust Preferred
Security may not be transferred except as a whole by the Depositary to a
nominee of such the Depositary or by a nominee of such the Depositary to such
Depositary or another nominee of such Depositary or by the Depositary or any
nominee to a successor Depositary or any nominee of such successor.
 
  Payments on Trust Preferred Securities represented by a global security will
be made to the Depositary, as the depositary for the Trust Preferred
Securities. In the event the Trust Preferred Securities are issued in
definitive form, Distributions will be payable, the transfer of the Trust
Preferred Securities will be registrable, and Trust Preferred Securities will
be exchangeable for Trust Preferred Securities of other denominations of a
like aggregate Liquidation Amount, at the corporate office of the Property
Trustee, or at the offices of any paying agent or transfer agent appointed by
the Administrative Trustees, provided that payment of any Distribution may be
made at the option of the Administrative Trustees by check mailed to the
address of the persons entitled thereto or by wire transfer. In addition, if
the Trust Preferred Securities are issued in certificated form, the record
dates for payment of Distributions will be the first day of the month in which
the relevant Distribution Date occurs. For a description of the terms of the
depositary arrangements relating to payments, transfers, voting rights,
redemptions and other notices and other matters, see "Book-Entry Issuance."
 
  Upon the issuance of a Global Trust Preferred Security, and the deposit of
such Global Trust Preferred Security with or on behalf of the Depositary, the
Depositary for such Global Trust Preferred Security or its nominee will
credit, on its book-entry registration and transfer system, the respective
aggregate Liquidation Amounts of the individual Trust Preferred Securities
represented by such Global Trust Preferred Securities to the accounts of
Participants. Such accounts shall be designated by the dealers, underwriters
or agents with respect to such Trust Preferred Securities. Ownership of
beneficial interests in a Global Trust Preferred Security will be limited to
Participants or persons that may hold interests through Participants.
Ownership of beneficial interests in such Global Trust Preferred Security will
be shown on, and the transfer of that ownership will be effected only through,
records maintained by the applicable Depositary or its nominee (with respect
to interests of Participants) and the records of Participants (with respect to
interests of persons who hold through Participants). The laws of some states
require that certain purchasers of securities take physical delivery of such
securities in definitive form. Such limits and such laws may impair the
ability to transfer beneficial interests in a Global Trust Preferred Security.
 
  So long as the Depositary for a Global Trust Preferred Security, or its
nominee, is the registered owners of such Global Trust Preferred Security,
such Depositary or such nominee, as the case may be, will be considered the
sole owner or holder of the Trust Preferred Securities represented by such
Global Trust Preferred Security for all purposes under the Trust Agreement
governing such Trust Preferred Securities. Except as provided below, owners of
beneficial interests in a Global Trust Preferred Security will not be entitled
to have any of the
 
                                      76
<PAGE>
 
individual Trust Preferred Securities represented by such Global Trust
Preferred Security registered in their names, will not receive or be entitled
to receive physical delivery of any such Trust Preferred Securities in
definitive form and will not be considered the owners or holders thereof under
the Trust Agreement.
 
  None of Greater Bay, the Property Trustee, any Paying Agent, or the
Securities Registrar (defined below) for such Trust Preferred Securities will
have any responsibility or liability for any aspect of the records relating to
or payments made on account of beneficial ownership interests of the Global
Trust Preferred Security representing such Trust Preferred Securities or for
maintaining supervising or reviewing any records relating to such beneficial
ownership interests.
 
  Greater Bay expects that the Depositary for Trust Preferred Securities or
its nominee, upon receipt of any payment of the Liquidation Amount or
Distributions in respect of a permanent Global Trust Preferred Security
immediately will credit Participants' accounts with payments in amounts
proportionate to their respective beneficial interest in the aggregate
Liquidation Amount of such Global Trust Preferred Security as shown on the
records of such Depositary or its nominee. Greater Bay also expects that
payments by Participants to owners of beneficial interests in such Global
Trust Preferred Security held through such Participants will be governed by
standing instructions and customary practices, as is now the case with
securities held for the accounts of customers in bearer form or registered in
"street name." Such payments will be the responsibility of such Participants.
 
  If the Depositary for the Trust Preferred Securities is at any time
unwilling, unable or ineligible to continue as depositary and a successor
depositary is not appointed by Greater Bay within 90 days, GBB Capital will
issue individual Trust Preferred Securities in exchange for the Global Trust
Preferred Security. In addition, GBB Capital may at any time and in its sole
discretion, subject to any limitations described herein relating to such Trust
Preferred Securities, determine not to have any Trust Preferred Securities
represented by one or more Global Trust Preferred Securities and, in such
event, will issue individual Trust Preferred Securities in exchange for the
Global Trust Preferred Security or Securities representing the Trust Preferred
Securities. Further, if GBB Capital so specifies with respect to the Trust
Preferred Securities, an owner of a beneficial interest in a Global Trust
Preferred Security representing Trust Preferred Securities may, on terms
acceptable to Greater Bay, the Property Trustee and the Depositary for such
Global Trust Preferred Security, receive individual Trust Preferred Securities
in exchange for such beneficial interests, subject to any limitations
described herein. In any such instance, an owner of a beneficial interest in a
Global Trust Preferred Security will be entitled to physical delivery of
individual Trust Preferred Securities represented by such Global Trust
Preferred Security equal in Liquidation Amount to such beneficial interest and
to have such Trust Preferred Securities registered in its name. Individual
Trust Preferred Securities so issued will be issued in denominations, unless
otherwise specified by GBB Capital, of $25 and integral multiples thereof.
 
PAYMENT AND PAYING AGENCY
 
  Payments in respect of the Trust Preferred Securities shall be made to the
Depositary, which shall credit the relevant accounts at the Depositary on the
applicable Distribution Dates or, if any of the Trust Preferred Securities are
not held by the Depositary, such payments shall be made by check mailed to the
address of the holder entitled thereto as such address shall appear on the
Register. The paying agent (the "Paying Agent") shall initially be the
Property Trustee and any co-paying agent chosen by the Property Trustee and
acceptable to the Administrative Trustees and Greater Bay. The Paying Agent
shall be permitted to resign as Paying Agent upon 30 days' written notice to
the Property Trustee and Trust Preferred. In the event that the Property
Trustee shall no longer be the Paying Agent, the Administrative Trustees shall
appoint a successor (which shall be a bank or trust company acceptable to the
Administrative Trustees and Greater Bay) to act as Paying Agent.
 
REGISTRAR AND TRANSFER AGENT
 
  The Property Trustee will act as registrar and transfer agent for the Trust
Preferred Securities. Registration of transfers of the Trust Preferred
Securities will be effected without charge by or on behalf of GBB Capital, but
 
                                      77
<PAGE>
 
upon payment of any tax or other governmental charges that may be imposed in
connection with any transfer or exchange. GBB Capital will not be required to
register or cause to be registered the transfer of the Trust Preferred
Securities after such Trust Preferred Securities have been called for
redemption.
 
INFORMATION CONCERNING THE PROPERTY TRUSTEE
 
  The Property Trustee, other than upon the occurrence and during the
continuance of an Event of Default, undertakes to perform only such duties as
are specifically set forth in the Trust Agreement and, after such Event of
Default, must exercise the same degree of care and skill as a prudent person
would exercise or use in the conduct of his or her own affairs. Subject to
this provision, the Property Trustee is under no obligation to exercise any of
the powers vested in it by the Trust Agreement at the request of any holder of
Trust Preferred Securities unless it is offered reasonable indemnity against
the costs, expenses and liabilities that might be incurred thereby. If no
Event of Default has occurred and is continuing and the Property Trustee is
required to decide between alternative causes of action, construe ambiguous
provisions in the Trust Agreement or is unsure of the application of any
provision of the Trust Agreement, and the matter is not one on which holders
of the Trust Preferred Securities are entitled under the Trust Agreement to
vote, then the Property Trustee shall take such action as is directed by
Greater Bay and if not so directed, shall take such action as it deems
advisable and in the best interests of the holders of the Trust Securities and
will have no liability except for its own bad faith, negligence or willful
misconduct.
 
MISCELLANEOUS
 
  The Administrative Trustees are authorized and directed to conduct the
affairs of and to operate GBB Capital in such a way that GBB Capital will not
be deemed to be an "investment company" required to be registered under the
Investment Company Act or classified as an association taxable as a
corporation for United States federal income tax purposes and so that the
Junior Subordinated Debentures will be treated as indebtedness of Greater Bay
for United States federal income tax purposes. In this connection, Greater Bay
and the Administrative Trustees are authorized to take any action, not
inconsistent with applicable law, the certificate of trust of GBB Capital or
the Trust Agreement, that Greater Bay and the Administrative Trustees
determine in their discretion to be necessary or desirable for such purposes,
as long as such action does not materially adversely affect the interests of
the holders of the Trust Preferred Securities. Holders of the Trust Preferred
Securities have no preemptive or similar rights.
 
  GBB Capital may not borrow money or issue debt or mortgage or pledge any of
its assets.
 
                 DESCRIPTION OF JUNIOR SUBORDINATED DEBENTURES
 
  The Junior Subordinated Debentures will be issued under the Junior
Subordinated Indenture, dated as of           , 1997 (the "Indenture"),
between Greater Bay and the Indenture Trustee. The following summary of the
terms and provisions of the Junior Subordinated Debentures and the Indenture
does not purport to be complete and is subject to, and is qualified in its
entirety by reference to, the Indenture, which has been filed as an exhibit to
the Registration Statement of which this Prospectus forms a part, and to the
Trust Indenture Act. The Indenture is qualified under the Trust Indenture Act.
Whenever particular defined terms of the Indenture are referred to herein,
such defined terms are incorporated herein or therein by reference.
 
  Concurrently with the issuance of the Trust Preferred Securities, GBB
Capital will invest the proceeds thereof, together with the consideration paid
by Greater Bay for the Common Securities, in Junior Subordinated Debentures
issued by Greater Bay. The Junior Subordinated Debentures will be issued as
unsecured debt under the Indenture.
 
 
                                      78
<PAGE>
 
GENERAL
 
  The Junior Subordinated Debentures will bear interest at the annual rate of
  % of the principal amount thereof, payable quarterly in arrears on the 15th
day of March, June, September and December of each year (each, an "Interest
Payment Date"), commencing June 15, 1997, to the person in whose name each
Junior Subordinated Debenture is registered, subject to certain exceptions, at
the close of business on the Business Day next preceding such Interest Payment
Date. Notwithstanding the above, in the event that either the (i) Junior
Subordinated Debentures are held by the Property Trustee and the Trust
Preferred Securities are no longer in book-entry only form or (ii) the Junior
Subordinated Debentures are not represented by a Global Subordinated Debenture
(as defined herein), the record date for such payment shall be the first day
of the month in which such payment is made. The amount of each interest
payment due with respect to the Junior Subordinated Debentures will include
amounts accrued through the date the interest payment is due. It is
anticipated that, until the liquidation, if any, of GBB Capital, each Junior
Subordinated Debenture will be held in the name of the Property Trustee in
trust for the benefit of the holders of the Trust Preferred Securities. The
amount of interest payable for any period will be computed on the basis of a
360-day year of twelve 30-day months. In the event that any date on which
interest is payable on the Junior Subordinated Debentures is not a Business
Day, then payment of the interest payable on such date will be made on the
next Business Day (and without any interest or other payment in respect of any
such delay), except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding
Business Day, in each case with the same force and effect as if made on the
date such payment was originally payable. Accrued interest that is not paid on
the applicable Interest Payment Date will bear additional interest on the
amount thereof (to the extent permitted by law) at the rate per annum of    %
thereof, compounded quarterly. The term "interest" as used herein shall
include quarterly interest payments, interest on quarterly interest payments
not paid on the applicable Interest Payment Date and Additional Sums (as
defined below), as applicable.
 
  The Junior Subordinated Debentures will mature on                 , 2026
(such date, as it may be shortened as hereinafter described, the "Stated
Maturity"). Such date may be shortened once at any time by Greater Bay to any
date not earlier than                  , 2002 subject to Greater Bay having
received prior approval of the Federal Reserve if then required under
applicable capital guidelines or policies of the Federal Reserve. In the event
that Greater Bay elects to shorten the Stated Maturity of the Junior
Subordinated Debentures, it shall give notice to the Indenture Trustee, and
the Indenture Trustee shall give notice of such shortening to the holders of
the Junior Subordinated Debentures no less than 90 days prior to the
effectiveness thereof.
 
  The Junior Subordinated Debentures will be unsecured and will rank junior
and be subordinate in right of payment to all Senior and Subordinated Debt of
Greater Bay. Because Greater Bay is a holding company, the right of Greater
Bay to participate in any distribution of assets of any subsidiaries,
including Greater Bay's Banks, upon any such subsidiaries' liquidation or
reorganization or otherwise (and thus the ability of holders of the Trust
Preferred Securities to benefit indirectly from such distribution), is subject
to the prior claims of creditors of that subsidiary, except to the extent that
Greater Bay may itself be recognized as a creditor of that subsidiary.
Accordingly, the Junior Subordinated Debentures will be effectively
subordinated to all existing and future liabilities of the Banks, and holders
of Junior Subordinated Debentures should look only to the assets of Greater
Bay for payments on the Junior Subordinated Debentures. The Indenture does not
limit the incurrence or issuance of other secured or unsecured debt of Greater
Bay, including Senior and Subordinated Debt, whether under the Indenture or
any existing or other indenture that Greater Bay may enter into in the future
or otherwise. See "--Subordination" below.
 
OPTION TO DEFER INTEREST PAYMENT PERIOD
 
  So long as no Debenture Event of Default has occurred and is continuing,
Greater Bay has the right under the Indenture at any time during the term of
the Junior Subordinated Debentures to defer the payment of interest at any
time or from time to time for a period not exceeding 20 consecutive quarters
(each such period an "Extension Period"), provided that no Extension Period
may extend beyond the Stated Maturity. At the end of such Extension Period,
Greater Bay must pay all interest then accrued and unpaid (together with
interest thereon
 
                                      79
<PAGE>
 
at the annual rate of   %, compounded quarterly, to the extent permitted by
applicable law). During an Extension Period, interest will continue to accrue
and holders of Junior Subordinated Debentures will be required to accrue
interest income for United States federal income tax purposes. See "Certain
Federal Income Tax Consequences--Interest Income and Original Issue Discount."
 
  During any such Extension Period, Greater Bay may not (i) declare or pay any
dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of Greater Bay's capital stock or
(ii) make any payment of principal, interest or premium, if any, on or repay,
repurchase or redeem any debt securities of Greater Bay (including other
Junior Subordinated Debentures) that rank pari passu with or junior in
interest to the Junior Subordinated Debentures or (iii) make any guarantee
payments with respect to any guarantee by Greater Bay of the debt securities
of any subsidiary of Greater Bay if such guarantee ranks pari passu with or
junior in interest to the Junior Subordinated Debentures (other than (a)
dividends or distributions in common stock of Greater Bay, (b) any declaration
of a dividend in connection with the implementation of a stockholders' rights
plan, or the issuance of stock under any such plan in the future, or the
redemption or repurchase of any such rights pursuant thereto, (c) payments
under the Guarantee, and (d) purchases of common stock related to the issuance
of common stock or rights under any of Greater Bay's benefit plans for its
directors, officers or employees). Prior to the termination of any such
Extension Period, Greater Bay may further extend such Extension Period,
provided that such extension does not cause such Extension Period to exceed 20
consecutive quarters or extend beyond the Stated Maturity. Upon the
termination of any such Extension Period and the payment of all amounts then
due on any Interest Payment Date, Greater Bay may elect to begin a new
Extension Period subject to the above requirements. No interest shall be due
and payable during an Extension Period, except at the end thereof. Greater Bay
must give the Property Trustee, the Administrative Trustees and the Indenture
Trustee notice of its election of any Extension Period at least one Business
Day prior to the earlier of (i) the date the Distributions on the Trust
Preferred Securities would have been payable except for the election to begin
or extend such Extension Period or (ii) the date the Administrative Trustees
are required to give notice to the New York Exchange, the Nasdaq National
Market or any applicable stock exchange or automated quotation system on which
the Trust Preferred Securities are then listed or quoted or to the holders of
the Trust Preferred Securities of the record date or the date such
Distributions are payable, but in any event not less than one Business Day
prior to such record date. The Indenture Trustee shall give notice of Greater
Bay's election to begin or extend a new Extension Period the holders of the
Trust Preferred Securities. There is no limitation on the number of times that
Greater Bay may elect to begin an Extension Period.
 
  Distributions on the Trust Preferred Securities will be deferred by GBB
Capital during any such Extension Period. See "Description of the Trust
Preferred Securities--Distributions." For a description of certain federal
income tax consequences and special considerations applicable to any such
Junior Subordinated Debentures, see "Certain Federal Income Tax Consequences."
 
ADDITIONAL SUMS
 
  If GBB Capital is required to pay any additional taxes, duties or other
governmental charges as a result of a Tax Event, Greater Bay will pay as
additional amounts on the Junior Subordinated Debentures such amounts
("Additional Sums") as shall be required so that the Distributions payable by
GBB Capital shall not be reduced as a result of any such additional taxes,
duties or other governmental charges.
 
REDEMPTION
 
  Subject to Greater Bay having received prior approval of the Federal
Reserve, if then required under applicable capital guidelines or policies of
the Federal Reserve, the Junior Subordinated Debentures are redeemable prior
to maturity at the option of Greater Bay (i) on or after        , 2002, in
whole at any time or in part from time to time, or (ii) at any time in whole
(but not in part), upon the occurrence and during the continuance of a Tax
Event, an Investment Company Event or a Capital Treatment Event, in each case
at a
 
                                      80
<PAGE>
 
redemption price equal to the accrued and unpaid interest on the Junior
Subordinated Debentures so redeemed to the date fixed for redemption, plus
100% of the principal amount thereof.
 
  Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each holder of Junior Subordinated
Debentures to be redeemed at such holder's registered address. Unless Greater
Bay defaults in payment of the redemption price, on and after the redemption
date interest ceases to accrue on such Junior Subordinated Debentures or
portions thereof called for redemption.
 
  If GBB Capital is required to pay additional taxes, duties or other
governmental charges as a result of a Tax Event, Greater Bay will pay as
additional amounts on the Junior Subordinated Debentures the Additional Sums
(as defined herein).
 
  The Junior Subordinated Debentures will not be subject to any sinking fund.
 
DISTRIBUTION UPON LIQUIDATION
 
  As described under "Description of the Trust Preferred Securities--
Liquidation Distribution Upon Termination," under certain circumstances
involving the termination of GBB Capital, the Junior Subordinated Debentures
may be distributed to the holders of the Trust Preferred Securities in
liquidation of GBB Capital after satisfaction of liabilities to creditors of
GBB Capital as provided by applicable law. If distributed to holders of the
Trust Preferred Securities in liquidation, the Junior Subordinated Debentures
will initially be issued in the form of one or more global securities and the
Depositary, or any successor depositary for the Trust Preferred Securities,
will act as depositary for the Junior Subordinated Debentures. It is
anticipated that the depositary arrangements for the Junior Subordinated
Debentures would be substantially identical to those in effect for the Trust
Preferred Securities. If the Junior Subordinated Debentures are distributed to
the holders of Trust Preferred Securities upon the liquidation of GBB Capital.
Greater Bay will use its best efforts to list the Junior Subordinated
Debentures on the Nasdaq National Market or such other stock exchanges or
automated quotation system, if any, on which the Trust Preferred Securities
are then listed or quoted. There can be no assurance as to the market price of
any Junior Subordinated Debentures that may be distributed to the holders of
Trust Preferred Securities.
 
RESTRICTIONS ON CERTAIN PAYMENTS
 
  If at any time (i) there shall have occurred any event of which Greater Bay
has actual knowledge that (a) with the giving of notice or the lapse of time,
or both, would constitute a Debenture Event of Default and (b) in respect of
which Greater Bay shall not have taken reasonable steps to cure, or (ii)
Greater Bay shall have given notice of its election of an Extension Period as
provided in the Indenture with respect to the Junior Subordinated Debentures
and shall not have rescinded such notice, or such Extension Period, or any
extension thereof, shall be continuing, or (iii) while the Junior Subordinated
Debentures are held by GBB Capital, Greater Bay shall be in default with
respect to its payment of any obligation under the Guarantee, then Greater Bay
will not (1) declare or pay any dividends or distributions on, or redeem,
purchase, acquire, or make a liquidation payment with respect to, any of
Greater Bay's capital stock or (2) make any payment of principal, interest or
premium, if any, on or repay, repurchase or redeem any debt securities of
Greater Bay (including other Junior Subordinated Debt) that rank pari passu
with or junior in interest to the Junior Subordinated Debentures or make any
guarantee payments with respect to any guarantee by Greater Bay of the debt
securities of any subsidiary of Greater Bay if such guarantee ranks pari passu
with or junior in interest to the Junior Subordinated Debentures (other than
(a) dividends or distributions in Common Stock, (b) any declaration of a
dividend in connection with the implementation of a stockholders' rights plan,
or the issuance of stock under any such plan in the future or the redemption
or repurchase of any such rights pursuant thereto, (c) payments under the
Guarantee and (d) purchases of Common Stock related to issuance of common
stock or rights under any of Greater Bay's benefit plans for its directors,
officers or employees) or related to the issuance of common stock (or
securities convertible into or exchangeable for common stock) as consideration
in an acquisition transaction.

SUBORDINATION
 
  In the Indenture, Greater Bay has covenanted and agreed that any Junior
Subordinated Debentures issued thereunder will be subordinate and junior in
right of payment to all Senior and Subordinated Debt to the extent provided in
the Indenture. Upon any payment or distribution of assets to creditors upon
any liquidation, dissolution, winding up, reorganization, assignment for the
benefit of creditors, marshaling of assets or any bankruptcy, insolvency, debt
restructuring or similar proceedings in connection with any insolvency or
bankruptcy proceeding of Greater Bay, the holders of Senior and Subordinated
Debt will first be entitled to receive payment in full of principal of all
Allocable Amounts (as defined below) on such Senior and Subordinated Debt
before the holders of Junior Subordinated Debentures will be entitled to
receive or retain any payment in respect thereof.
 
  In the event of the acceleration of the maturity of any Junior Subordinated
Debentures, the holders of all Senior and Subordinated Debt outstanding at the
time of such acceleration will first be entitled to receive payment in full of
all amounts due thereon (including any amounts due upon acceleration) before
the holders of Junior Subordinated Debentures will be entitled to receive or
retain any payment in respect of the Junior Subordinated Debentures.
 
  No payments on account of principal or interest, if any, in respect of the
Junior Subordinated Debentures may be made if there shall have occurred and be
continuing a default in any payment with respect to Senior and Subordinated
Debt or an event of default with respect to any Senior and Subordinated Debt
resulting in the acceleration of the maturity thereof, or if any judicial
proceeding shall be pending with respect to any such default.
 
  "Allocable Amounts," when used with respect to any Senior and Subordinated
Debt, means all amounts due or to become due on such Senior and Subordinated
Debt less, if applicable, any amount which would have been paid to, and
retained by, the holders of such Senior and Subordinated Debt (whether as a
result of the receipt of payments by the holders of such Senior and
Subordinated Debt from Greater Bay or any other obligor thereon or from any
holders of, or trustee in respect of, other indebtedness that is subordinate
and junior in right of payment to such Senior and Subordinated Debt pursuant
to any provision of such indebtedness for the payment over of amounts received
on account of such indebtedness to the holders of such Senior and Subordinated
Debt or otherwise) but for the fact that such Senior and Subordinated Debt is
subordinated or junior in right of payment to (or subject to a requirement
that amounts received on such Senior and Subordinated Debt be paid over to
obligees on) trade accounts payable or accrued liabilities arising in the
ordinary course of business.
 
  "Debt" means with respect to any person, whether recourse is to all or a
portion of the assets of such person and whether or not contingent: (i) every
obligation of such person for money borrowed; (ii) every obligation of such
person evidenced by bonds, debentures, notes or other similar instruments,
including obligations incurred in connection with the acquisition of property,
assets or businesses; (iii) every reimbursement obligation of such person with
respect to letters of credit, bankers' acceptances or similar facilities
issued for the account of such person; (iv) every obligation of such person
issued or assumed as the deferred purchase price of property or services (but
excluding trade accounts payable or accrued liabilities arising in the
ordinary course of business); (v) every capital lease obligation of such
person; (vi) all indebtedness of such person whether incurred on or prior to
the date of the Indenture or thereafter incurred, for claims in respect of
derivative products including interest rate, foreign exchange rate and
commodity forward contracts, options and swaps and similar arrangements; and
(vii) every obligation of the type referred to in clauses (i) through (vi) of
another person and all dividends of another person the payment of which, in
either case, such person has guaranteed or is responsible or liable, directly
or indirectly, as obligor or otherwise.
 
  "Senior and Subordinated Debt" means the principal of (and premium, if any)
and interest, if any (including interest accruing on or after the filing of
any petition in bankruptcy or for reorganization relating to Greater Bay
whether or not such claim for post-petition interest is allowed in such
proceeding), on Debt of Greater Bay whether incurred on or prior to the date
of the Indenture or thereafter incurred, unless, in the
 
                                      82
<PAGE>
 
instrument creating or evidencing the same or pursuant to which the same is
outstanding, it is provided that such obligations are not superior in right of
payment to the Junior Subordinated Debentures or to other Debt which is pari
passu with, or subordinated to, the Junior Subordinated Debentures; provided,
however, that Senior and Subordinated Debt shall not be deemed to include (i)
any Debt of Greater Bay which when incurred and without respect to any
election under section 1111(b) of the United States Bankruptcy Code of 1978,
as amended, was without recourse to Greater Bay, (ii) any Debt of Greater Bay
to any of its subsidiaries, (iii) Debt to any employee of Greater Bay, and
(iv) any other debt securities issued pursuant to the Indenture.
 
  The Indenture places no limitation on the amount of additional Senior and
Subordinated Debt that may be incurred by Greater Bay. Greater Bay expects
from time to time to incur additional indebtedness constituting Senior and
Subordinated Debt.
 
DENOMINATIONS, REGISTRATION AND TRANSFER
 
  The Junior Subordinated Debentures will be represented by global
certificates registered in the name of the Depositary or its nominee ("Global
Subordinated Debenture"). Beneficial interests in the Junior Subordinated
Debentures will be shown on, and transfers thereof will be effected only
through, records maintained by the Depositary. Except as described below,
Junior Subordinated Debentures in certificated form will not be issued in
exchange for the global certificates. See "Book-Entry Issuance."
 
  Unless and until a Global Subordinated Debenture is exchanged in whole or in
part for the individual Junior Subordinated Debentures represented thereby, it
may not be transferred except as a whole by the Depositary for such Global
Subordinated Debenture to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary or by the
Depositary or any nominee to a successor Depositary or any nominee of such
successor.
 
  A global security shall be exchangeable for Junior Subordinated Debentures
registered in the names of persons other than the Depositary or its nominee
only if (i) the Depositary notifies Greater Bay that it is unwilling or unable
to continue as a depositary for such global security and no successor
depositary shall have been appointed, or if at any time the Depositary ceases
to be a clearing agency registered under the Securities Exchange Act, at a
time when the Depositary is required to be so registered to act as such
depositary, (ii) Greater Bay in its sole discretion determines that such
global security shall be so exchangeable or (iii) there shall have occurred
and be continuing a Debenture Event of Default with respect to such global
security. Any global security that is exchangeable pursuant to the preceding
sentence shall be exchangeable for definitive certificates registered in such
names as the Depositary shall direct. It is expected that such instructions
will be based upon directions received by the Depositary from its Participants
with respect to ownership of beneficial interests in such global security. In
the event that Junior Subordinated Debentures are issued in definitive form,
such Junior Subordinated Debentures will be in denominations of $25 and
integral multiples thereof and may be transferred or exchanged at the offices
described below.
 
  Payments on Junior Subordinated Debentures represented by a global security
will be made to the Depositary, as the depositary for the Junior Subordinated
Debentures. In the event Junior Subordinated Debentures are issued in
definitive form, principal and interest will be payable, the transfer of the
Junior Subordinated Debentures will be registrable, and Junior Subordinated
Debentures will be exchangeable for Junior Subordinated Debentures of other
denominations of a like aggregate principal amount, at the corporate office of
the Indenture Trustee, or at the offices of any paying agent or transfer agent
appointed by Greater Bay, provided that payment of interest may be made at the
option of Greater Bay by check mailed to the address of the persons entitled
thereto or by wire transfer. In addition, if the Junior Subordinated
Debentures are issued in certificated form, the record dates for payment of
interest will be the first day of the month in which such payment is to be
made. For a description of the Depositary and the terms of the depositary
arrangements relating to payments, transfers, voting rights, redemptions and
other notices and other matters, see "Book-Entry Issuance."
 
 
                                      83
<PAGE>
 
  Greater Bay will appoint the Indenture Trustee as securities registrar under
the Indenture (the "Securities Registrar"). Junior Subordinated Debentures may
be presented for exchange as provided above, and may be presented for
registration of transfer (with the form of transfer endorsed thereon, or a
satisfactory written instrument of transfer, duly executed), at the office of
the Securities Registrar. Greater Bay may at any time rescind the designation
of any such transfer agent or approve a change in the location through which
any such transfer agent acts, provided that Greater Bay maintains a transfer
agent in the place of payment. Greater Bay may at any time designate
additional transfer agents with respect to the Junior Subordinated Debentures.
 
  In the event of any redemption, neither Greater Bay nor the Indenture
Trustee shall be required to (i) issue, register the transfer of or exchange
Junior Subordinated Debentures during a period beginning at the opening of
business 15 days before the day of selection for redemption of Junior
Subordinated Debentures and ending at the close of business on the day of
mailing of the relevant notice of redemption or (ii) transfer or exchange any
Junior Subordinated Debentures so selected for redemption, except, in the case
of any Junior Subordinated Debentures being redeemed in part, any portion
thereof not to be redeemed.
 
GLOBAL SUBORDINATED DEBENTURES
 
  Upon the issuance of the Global Subordinated Debenture, and the deposit of
such Global Subordinated Debenture with or on behalf of the Depositary, the
Depositary for such Global Subordinated Debenture or its nominee will credit,
on its book-entry registration and transfer system, the respective principal
amounts of the individual Junior Subordinated Debentures represented by such
Global Subordinated Debenture to the accounts of persons that have accounts
with such Depositary ("Participants"). Ownership of beneficial interests in a
Global Subordinated Debenture will be limited to Participants or persons that
may hold interests through Participants. Ownership of beneficial interests in
such Global Subordinated Debenture will be shown on, and the transfer of that
ownership will be effected only through, records maintained by the applicable
Depositary or its nominee (with respect to interests of Participants) and the
records of Participants (with respect to interests of persons who hold through
Participants). The laws of some states require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to transfer beneficial interests
in a Global Subordinated Debenture.
 
  So long as the Depositary for a Global Subordinated Debenture, or its
nominee, is the registered owner of such Global Subordinated Debenture, such
Depositary or such nominee, as the case may be, will be considered the sole
owner or holder of the Junior Subordinated Debentures represented by such
Global Subordinated Debenture for all purposes under the Indenture governing
such Junior Subordinated Debentures. Except as provided below, owners of
beneficial interests in a Global Subordinated Debenture will not be entitled
to have any of the individual Junior Subordinated Debentures represented by
such Global Subordinated Debenture registered in their names, will not receive
or be entitled to receive physical delivery of any such Junior Subordinated
Debentures in definitive form and will not be considered the owners or holders
thereof under the Indenture.
 
  Payments of principal of and interest on individual Junior Subordinated
Debentures represented by a Global Subordinated Debenture registered in the
name of the Depositary or its nominee will be made to the Depositary or its
nominee, as the case may be, as the registered owner of the Global
Subordinated Debenture representing such Junior Subordinated Debentures. None
of Greater Bay, the Indenture Trustee, any Paying Agent, or the Securities
Registrar for such Junior Subordinated Debentures will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests of the Global Subordinated Debenture
representing such Junior Subordinated Debentures or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.
 
  Greater Bay expects that the Depositary or its nominee, upon receipt of any
payment of principal or interest in respect of a permanent Global Subordinated
Debenture representing the Junior Subordinated Debentures, immediately will
credit Participants' accounts with payments in amounts proportionate to their
respective beneficial interest in the principal amount of the Global
Subordinated Debenture as shown on the records of such
 
                                      84
<PAGE>
 
Depositary or its nominee. Greater Bay also expects that payments by
Participants to owners of beneficial interests in such Global Subordinated
Debenture held through such Participants will be governed by standing
instructions and customary practices, as is now the case with securities held
for the accounts of customers in bearer form or registered in "street name."
Such payments will be the responsibility of such Participants.
 
  If the Depositary is at any time unwilling, unable or ineligible to continue
as depositary and a successor depositary is not appointed by Greater Bay
within 90 days, Greater Bay will issue individual Junior Subordinated
Debentures in exchange for the Global Subordinated Debenture. In addition,
Greater Bay may at any time and in its sole discretion, determine not to have
the Junior Subordinated Debentures represented by one or more Global Junior
Subordinated Debentures and, in such event, will issue individual Junior
Subordinated Debentures in exchange for the Global Subordinated Debenture.
Further, if Greater Bay so specifies with respect to the Junior Subordinated
Debentures, an owner of a beneficial interest in a Global Subordinated
Debenture representing Junior Subordinated Debentures may, on terms acceptable
to Greater Bay, the Indenture Trustee and the Depositary for such Global
Subordinated Debenture, receive individual Junior Subordinated Debentures in
exchange for such beneficial interests. In any such instance, an owner of a
beneficial interest in a Global Subordinated Debenture will be entitled to
physical delivery of individual Junior Subordinated Debentures equal in
principal amount to such beneficial interest and to have such Junior
Subordinated Debentures registered in its name. Individual Junior Subordinated
Debentures so issued will be issued in denominations, unless otherwise
specified by Greater Bay, of $25 and integral multiples thereof.
 
PAYMENT AND PAYING AGENTS
 
  Payment of principal of and any interest on the Junior Subordinated
Debentures will be made at the office of the Indenture Trustee, except that at
the option of Greater Bay payment of any interest may be made (i) except in
the case of Global Junior Subordinated Debentures, by check mailed to the
address of the person entitled thereto as such address shall appear in the
securities register or (ii) by transfer to an account maintained by the person
entitled thereto as specified in the securities register, provided that proper
transfer instructions have been received by the regular record date. Payment
of any interest on Junior Subordinated Debentures will be made to the person
in whose name such Junior Subordinated Debenture is registered at the close of
business on the regular record date for such interest. Greater Bay may at any
time designate additional Paying Agents or rescind the designation of any
Paying Agent; however Greater Bay will at all times be required to maintain a
Paying Agent in each place of payment for the Junior Subordinated Debentures.
Any moneys deposited with the Indenture Trustee or any Paying Agent, or then
held by Greater Bay in trust, for the payment of the principal of or interest
on the Junior Subordinated Debentures and remaining unclaimed for two years
after such principal or interest has become due and payable shall, at the
request of Greater Bay, be repaid to Greater Bay and the holder of such Junior
Subordinated Debenture shall thereafter look, as a general unsecured creditor,
only to Greater Bay for payment thereof.
 
MODIFICATION OF INDENTURE
 
  From time to time Greater Bay and the Indenture Trustee may, without the
consent of the holders of the Junior Subordinated Debentures, amend, waive or
supplement the Indenture for specified purposes, including, among other
things, curing ambiguities, defects or inconsistencies (provided that any such
action does not materially adversely affect the interests of the holders of
the Junior Subordinated Debentures or the Trust Preferred Securities so long
as they remain outstanding) and qualifying, or maintaining the qualification
of, the Indenture under the Trust Indenture Act. The Indenture contains
provisions permitting Greater Bay and the Indenture Trustee, with the consent
of the holders of not less than a majority in principal amount of the
outstanding Junior Subordinated Debentures, to modify the Indenture in a
manner affecting the rights of the holders of the Junior Subordinated
Debentures; provided, that no such modification may, without the consent of
the holder of each outstanding Subordinated Debenture, (i) change the Stated
Maturity of the Junior Subordinated Debentures, or reduce the principal amount
thereof, or reduce the rate or extend the time of payment of interest thereon
or (ii) reduce the percentage of principal amount of Junior Subordinated
Debentures, the holders of which
 
                                      85
<PAGE>
 
are required to consent to any such modification of the Indenture, provided
that so long as any of the Trust Preferred Securities remain outstanding, no
such modification may be made that adversely affects the holders of such Trust
Preferred Securities in any material respect, and no termination of the
Indenture may occur, and no waiver of any Debenture Event of Default or
compliance with any covenant under the Indenture may be effective, without the
prior consent of the holders of at least a majority of the aggregate
Liquidation Amount of the Trust Preferred Securities unless and until the
principal of the Junior Subordinated Debentures and all accrued and unpaid
interest thereon have been paid in full and certain other conditions are
satisfied. Where a consent under the Indenture would require the consent of
each holder of Junior Subordinated Debentures, no such consent shall be given
by the Property Trustee without the prior consent of each holder of Trust
Preferred Securities. In addition, Greater Bay and the Indenture Trustee may
execute, without the consent of any holder of Junior Subordinated Debentures,
any supplemental Indenture for the purpose of creating any new series of
Junior Subordinated Debentures.
 
DEBENTURE EVENTS OF DEFAULT
 
  The Indenture provides that any one or more of the following described
events with respect to the Junior Subordinated Debentures that has occurred
and is continuing constitutes a "Debenture Event of Default" with respect to
the Junior Subordinated Debentures:
 
    (i) failure for 30 days to pay any interest on the Junior Subordinated
  Debentures, when due (subject to the deferral of any due date in the case
  of an Extension Period); or
 
    (ii) failure to pay any principal on the Junior Subordinated Debentures
  when due whether at maturity, upon redemption by declaration or otherwise;
  or
 
    (iii) failure to observe or perform in any material respect certain other
  covenants contained in the Indenture for 90 days after written notice to
  Greater Bay from the Indenture Trustee or to Greater Bay and the Indenture
  Trustee by the holders of at least 25% in aggregate outstanding principal
  amount of the Junior Subordinated Debentures; or
 
    (iv) certain events in bankruptcy, insolvency or reorganization of
  Greater Bay.
 
  The holders of a majority in aggregate outstanding principal amount of the
Junior Subordinated Debentures have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Indenture
Trustee. The Indenture Trustee or the holders of not less than 25% in
aggregate outstanding principal amount of the Junior Subordinated Debentures
may declare the principal due and payable immediately upon a Debenture Event
of Default. If the Indenture Trustee or such holders of such Junior
Subordinated Debentures fail to make such declaration, the holders of at least
25% in aggregate Liquidation Amount of the Trust Preferred Securities shall
have such right. The holders of a majority in aggregate outstanding principal
amount of the Junior Subordinated Debentures may annul such declaration and
waive the default if the default (other than the non-payment of the principal
of the Junior Subordinated Debentures which has become due solely by such
acceleration) has been cured and a sum sufficient to pay all matured
installments of interest and principal due otherwise than by acceleration has
been deposited with the Indenture Trustee. Should the holders of the Junior
Subordinated Debentures fail to annul such declaration and waive such default,
the holders of a majority in aggregate Liquidation Amount of the Trust
Preferred Securities shall have such right.
 
  The holders of a majority in aggregate outstanding principal amount of
Junior Subordinated Debentures affected thereby may, on behalf of the holders
of all the Junior Subordinated Debentures, waive any past default, except a
default in the payment of principal or interest (unless such default has been
cured and a sum sufficient to pay all matured installments of interest and
principal due otherwise than by acceleration has been deposited with the
Indenture Trustee) or a default in respect of a covenant or provision which
under the Indenture cannot be modified or amended without the consent of the
holder of each outstanding Junior Subordinated Debenture.
 
  In case a Debenture Event of Default shall occur and be continuing as to the
Junior Subordinated Debentures, the Property Trustee will have the right to
declare the principal of and the interest on such Junior
 
                                      86
<PAGE>
 
Subordinated Debentures, and any other amounts payable under the Indenture, to
be forthwith due and payable and to enforce its other rights as a creditor with
respect to such Junior Subordinated Debentures.
 
  Greater Bay is required to file annually with the Indenture Trustee a
certificate as to whether or not Greater Bay is in compliance with all the
conditions and covenants applicable to it under the Indenture.
 
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF TRUST PREFERRED SECURITIES
 
  If a Debenture Event of Default has occurred and is continuing and such event
is attributable to the failure of Greater Bay to pay interest or principal on
the Junior Subordinated Debentures on the date such interest or principal is
otherwise payable, a holder of Trust Preferred Securities may institute a legal
proceeding directly against Greater Bay for enforcement of payment to such
holder of the principal of or interest on such Junior Subordinated Debentures
having a principal amount equal to the aggregate Liquidation Amount of the
Trust Preferred Securities of such holder ("Direct Action"). Greater Bay may
not amend the Indenture to remove the foregoing right to bring a Direct Action
without the prior written consent of the holders of all of the Trust Preferred
Securities outstanding. If the right to bring a Direct Action is removed, GBB
Capital may become subject to the reporting obligations under the Exchange Act.
Greater Bay shall have the right under the Indenture to set-off any payment
made to such holder of Trust Preferred Securities by Greater Bay in connection
with a Direct Action.
 
  The holders of the Trust Preferred Securities would not be able to exercise
directly any remedies other than those set forth in the preceding paragraph
available to the holders of the Junior Subordinated Debentures unless there
shall have been an Event of Default under the Trust Agreement. See "Description
of the Trust Preferred Securities--Events of Default; Notice."
 
CONSOLIDATION, MERGER, SALE OF ASSETS AND OTHER TRANSACTIONS
 
  The Indenture provides that Greater Bay shall not consolidate with or merge
into any other Person or convey, transfer or lease its properties and assets
substantially as an entirety to any Person, and no Person shall consolidate
with or merge into Greater Bay or convey, transfer or lease its properties and
assets substantially as an entirety to Greater Bay, unless (i) in case Greater
Bay consolidates with or merges into another Person or conveys or transfers its
properties and assets substantially as an entirety to any Person, the successor
Person is organized under the laws of the United States or any state or the
District of Columbia, and such successor Person expressly assumes Greater Bay's
obligations on the Junior Subordinated Debentures issued under the Indenture;
(ii) immediately after giving effect thereto, no Debenture Event of Default,
and no event which, after notice or lapse of time or both, would become a
Debenture Event of Default, shall have occurred and be continuing; (iii) such
transaction is permitted under the Trust Agreement and the Guarantee Agreement;
and does not give rise to any breach or violation of the Trust Agreement or
Guarantee Agreement; and (iv) certain other conditions as prescribed in the
Indenture are met.
 
  The general provisions of the Indenture do not afford holders of the Junior
Subordinated Debentures protection in the event of a highly leveraged or other
transaction involving Greater Bay that may adversely affect holders of the
Junior Subordinated Debentures.
 
SATISFACTION AND DISCHARGE
 
  The Indenture provides that when, among other things, all Junior Subordinated
Debentures not previously delivered to the Indenture Trustee for cancellation
(i) have become due and payable or (ii) will become due and payable at their
Stated Maturity within one year, and Greater Bay deposits or causes to be
deposited with the Indenture Trustee trust funds, in trust, for the purpose and
in an amount in the currency or currencies in which the Junior Subordinated
Debentures are payable sufficient to pay and discharge the entire indebtedness
on the Junior Subordinated Debentures not previously delivered to the Indenture
Trustee for cancellation, for the principal and interest to the date of the
deposit or to the Stated Maturity, as the case may be, then the Indenture will
cease to be of further effect (except as to Greater Bay's obligations to pay
all other sums due pursuant to the Indenture and to provide the officers'
certificates and opinions of counsel described therein), and Greater Bay will
be deemed to have satisfied and discharged the Indenture.
 
 
                                       87
<PAGE>
 
COVENANTS OF GREATER BAY
 
  Greater Bay will covenant in the Indenture, as to the Junior Subordinated
Debentures, that if and so long as (i) GBB Capital is the holder of all such
Junior Subordinated Debentures, (ii) a Tax Event in respect of GBB Capital has
occurred and is continuing and (iii) Greater Bay has elected, and has not
revoked such election, to pay Additional Sums (as defined under "Description
of the Trust Preferred Securities--Redemption") in respect of the Trust
Preferred Securities, Greater Bay will pay to GBB Capital such Additional
Sums. Greater Bay will also covenant, as to the Junior Subordinated
Debentures, (i) to maintain directly or indirectly 100% ownership of the
Common Securities of GBB Capital to which Junior Subordinated Debentures have
been issued, provided that certain successors which are permitted pursuant to
the Indenture may succeed to Greater Bay's ownership of the Common Securities,
(ii) not to voluntarily terminate, wind up or liquidate GBB Capital, except
upon prior approval of the Federal Reserve if then so required under
applicable capital guidelines or policies of the Federal Reserve, and except
(a) in connection with a distribution of Junior Subordinated Debentures to the
holders of the Trust Preferred Securities in liquidation of GBB Capital or (b)
in connection with certain mergers, consolidations, or amalgamations permitted
by the Trust Agreement and (iii) to use its reasonable efforts, consistent
with the terms and provisions of the Trust Agreement, to cause GBB Capital to
remain classified as a grantor trust and not as an association taxable as a
corporation for United States federal income tax purposes.
 
GOVERNING LAW
 
  The Indenture and the Junior Subordinated Debentures will be governed by and
construed in accordance with the laws of the State of California.
 
INFORMATION CONCERNING THE INDENTURE TRUSTEE
 
  The Indenture Trustee shall have and be subject to all the duties and
responsibilities specified with respect to an indenture trustee under the
Trust Indenture Act. Subject to such provisions, the Indenture Trustee is
under no obligation to exercise any of the powers vested in it by the
Indenture at the request of any holder of Junior Subordinated Debentures,
unless offered reasonable indemnity by such holder against the costs, expenses
and liabilities which might be incurred thereby. The Indenture Trustee is not
required to expend or risk its own funds or otherwise incur personal financial
liability in the performance of its duties if the Indenture Trustee reasonably
believes that repayment or adequate indemnity is not reasonably assured to it.
 
                              BOOK-ENTRY ISSUANCE
 
  The Depositary will act as securities depositary for all of the Trust
Preferred Securities and the Junior Subordinated Debentures. The Trust
Preferred Securities and the Junior Subordinated Debentures will be issued
only as fully-registered securities registered in the name of Cede & Co. (the
Depositary's nominee). One or more fully-registered global certificates will
be issued for the Trust Preferred Securities and the Junior Subordinated
Debentures and will be deposited with the Depositary.
 
  The Depositary is a limited purpose trust company organized under the New
York Banking Law, a "banking organization" within the meaning of the New York
Banking Law, a member of the Federal Reserve System, a "clearing corporation"
within the meaning of the New York Uniform Commercial Code, and a "clearing
agency" registered pursuant to the provisions of Section 17A of the Exchange
Act. The Depositary holds securities that its Participants deposit with the
Depositary. The Depositary also facilitates the settlement among Participants
of securities transactions, such as transfers and pledges, in deposited
securities through electronic computerized book-entry changes in Participants'
accounts, thereby eliminating the need for physical movement of securities
certificates. "Direct Participants" include securities brokers and dealers,
banks, trust companies, clearing corporations and certain other organizations.
The Depositary is owned by a number of its Direct Participants and by the New
York Stock Exchange, Inc., the American Stock Exchange, Inc. and the
 
                                      88
<PAGE>
 
National Association of Securities Dealers, Inc. Access to the Depositary
system is also available to others such as securities brokers and dealers,
banks and trust companies that clear through or maintain custodial
relationships with Direct Participants, either directly or indirectly
("Indirect Participants"). The rules applicable to the Depositary and its
Participants are on file with the Commission.
 
  Purchases of Trust Preferred Securities or Junior Subordinated Debentures
within the Depositary system must be made by or through Direct Participants,
which will receive a credit for the Trust Preferred Securities or Junior
Subordinated Debentures on the Depositary's records. The ownership interest of
each actual purchaser of each Trust Preferred Securities and each Subordinated
Debenture ("Beneficial Owner") is in turn to be recorded on the Direct and
Indirect Participants' records. Beneficial Owners will not receive written
confirmation from the Depositary of their purchases, but Beneficial Owners are
expected to receive written confirmations providing details of the
transactions, as well as periodic statements of their holdings, from the
Direct or Indirect Participants through which the Beneficial Owners purchased
Trust Preferred Securities or Junior Subordinated Debentures. Transfers of
ownership interests in the Trust Preferred Securities or Junior Subordinated
Debentures are to be accomplished by entries made on the books of Participants
acting on behalf of Beneficial Owners. Beneficial Owners will not receive
certificates representing their ownership interests in Trust Preferred
Securities or Junior Subordinated Debentures, except in the event that use of
the book-entry system for the or Junior Subordinated Debentures is
discontinued.
 
  The Depositary has no knowledge of the actual Beneficial Owners of the Trust
Preferred Securities or Junior Subordinated Debentures; the Depositary's
records reflect only the identity of the Direct Participants to whose accounts
such Trust Preferred Securities or Junior Subordinated Debentures are
credited, which may or may not be the Beneficial Owners. The Participants will
remain responsible for keeping account of their holdings on behalf of their
customers.
 
  Conveyance of notices and other communications by the Depositary to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners and the voting
rights of Direct Participants, Indirect Participants and Beneficial Owners
will be governed by arrangements among them, subject to any statutory or
regulatory requirements as may be in effect from time to time.
 
  Redemption notices will be sent to Cede & Co. as the registered holder of
the Trust Preferred Securities or Junior Subordinated Debentures. If less than
all of the Trust Preferred Securities or the Junior Subordinated Debentures
are being redeemed, the Depositary will determine by lot or pro rata the
amount of the Trust Preferred Securities of each Direct Participant to be
redeemed.
 
  Although voting with respect to the Trust Preferred Securities or the Junior
Subordinated Debentures is limited to the holders of record of the Trust
Preferred Securities or Junior Subordinated Debentures, as applicable, in
those instances in which a vote is required, neither the Depositary nor Cede &
Co. will itself consent or vote with respect to Trust Preferred Securities or
Junior Subordinated Debentures. Under its usual procedures, the Depositary
would mail an omnibus proxy (the "Omnibus Proxy") to the relevant Trustee as
soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.'s
consenting or voting rights to those Direct Participants to whose accounts
such Trust Preferred Securities or Junior Subordinated Debentures are credited
on the record date (identified in a listing attached to the Omnibus Proxy).
 
  Distribution payments on the Trust Preferred Securities or the Junior
Subordinated Debentures will be made by the relevant Trustee to the
Depositary. The Depositary's practice is to credit Direct Participants'
accounts on the relevant payment date in accordance with their respective
holdings shown on the Depositary's records unless the Depositary has reason to
believe that it will not receive payments on such payment date. Payments by
Participants to Beneficial Owners will be governed by standing instructions
and customary practices and will be the responsibility of such Participant and
not of the Depositary, the relevant Trustee, GBB Capital or Greater Bay,
subject to any statutory or regulatory requirements as may be in effect from
time to time. Payment of Distributions to the Depositary is the responsibility
of the relevant Trustee, disbursement of such payments to
 
                                      89
<PAGE>
 
Direct Participants is the responsibility of the Depositary, and disbursements
of such payments to the Beneficial Owners is the responsibility of Direct and
Indirect Participants.
 
  The Depositary may discontinue providing its services as securities
depositary with respect to any of the Trust Preferred Securities or the Junior
Subordinated Debentures at any time by giving reasonable notice to the
relevant Trustee and Greater Bay. In the event that a successor securities
depositary is not obtained, definitive Trust Preferred Securities or
Subordinated Debenture certificates representing such Trust Preferred
Securities or Junior Subordinated Debentures are required to be printed and
delivered. Greater Bay, at its option, may decide to discontinue use of the
system of book-entry transfers through the Depositary (or a successor
depositary). After a Debenture Event of Default, the holders of a majority in
liquidation preference of Trust Preferred Securities or aggregate principal
amount of Junior Subordinated Debentures may determine to discontinue the
system of book-entry transfers through the Depositary. In any such event,
definitive certificates for such Trust Preferred Securities or Junior
Subordinated Debentures will be printed and delivered.
 
  The information in this section concerning the Depositary and the
Depositary's book-entry system has been obtained from sources that GBB Capital
and Greater Bay believe to be accurate, but GBB Capital and Greater Bay assume
no responsibility for the accuracy thereof. Neither GBB Capital nor Greater
Bay has any responsibility for the performance by the Depositary or its
Participants of their respective obligations as described herein or under the
rules and procedures governing their respective operations.
 
                           DESCRIPTION OF GUARANTEE
 
  The Guarantee Agreement will be executed and delivered by Greater Bay
concurrently with the issuance of the Trust Preferred Securities for the
benefit of the holders of the Trust Preferred Securities. Wilmington Trust
Company will act as Guarantee Trustee under the Guarantee Agreement for the
purposes of compliance with the Trust Indenture Act, and the Guarantee will be
qualified as an Indenture under the Trust Indenture Act. The following summary
of certain provisions of the Guarantee does not purport to be complete and is
subject to, and qualified in its entirety by reference to, all of the
provisions of the Guarantee Agreement, including the definitions therein of
certain terms, and the Trust Indenture Act. The form of the Guarantee has been
filed as an exhibit to the Registration Statement of which this Prospectus
forms a part. The Guarantee Trustee will hold the Guarantee for the benefit of
the holders of the Trust Preferred Securities.
 
GENERAL
 
  The Guarantee will be an irrevocable guarantee on a subordinated basis of
GBB Capital's obligations under the Trust Preferred Securities, but will apply
only to the extent that GBB Capital has funds sufficient to make such
payments, and is not a guarantee of collection.
 
  Greater Bay will irrevocably agree to pay in full on a subordinated basis,
to the extent set forth herein, the Guarantee Payments (as defined below) to
the holders of the Trust Preferred Securities, as and when due, regardless of
any defense, right of set-off or counterclaim that GBB Capital may have or
assert other than the defense of payment. The following payments with respect
to the Trust Preferred Securities, to the extent not paid by or on behalf of
GBB Capital (the "Guarantee Payments"), will be subject to the Guarantee: (i)
any accumulated and unpaid Distributions required to be paid on the Trust
Preferred Securities, to the extent that GBB Capital has funds on hand
available therefor at such time, (ii) the redemption price with respect to any
Trust Preferred Securities called for redemption, to the extent that GBB
Capital has funds on hand available therefor at such time, and (iii) upon a
voluntary or involuntary dissolution, winding up or liquidation of GBB Capital
(unless the Junior Subordinated Debentures are distributed to holders of the
Trust Preferred Securities), the lesser of (a) the Liquidation Distribution
and (b) the amount of assets of GBB Capital remaining available for
distribution to holders of Trust Preferred Securities after satisfaction of
liabilities to creditors of GBB Capital as required by law. Greater Bay's
obligation to make a Guarantee Payment may be satisfied by direct payment of
the required amounts by Greater Bay to the holders of the Trust Preferred
Securities or by causing GBB Capital to pay such amounts to such holders.
 
                                      90
<PAGE>
 
  If Greater Bay does not make interest payments on the Junior Subordinated
Debentures held by GBB Capital, GBB Capital will not be able to pay
Distributions on the Trust Preferred Securities and will not have funds
legally available therefor. The Guarantee will rank subordinate and junior in
right of payment to all Senior and Subordinated Debt of Greater Bay. See
"Status of the Guarantee" below. Because Greater Bay is a holding company, the
right of Greater Bay to participate in any distribution of assets of any
subsidiary upon such subsidiary's liquidation or reorganization or otherwise,
is subject to the prior claims of creditors of that subsidiary, except to the
extent Greater Bay may itself be recognized as a creditor of that subsidiary.
Accordingly, Greater Bay's obligations under the Guarantee will be effectively
subordinated to all existing and future liabilities of Greater Bay's
subsidiaries, and claimants should look only to the assets of Greater Bay for
payments thereunder. Except as otherwise described herein, the Guarantee does
not limit the incurrence or issuance of other secured or unsecured debt of
Greater Bay, including Senior and Subordinated Debt whether under the
Indenture, any other indenture that Greater Bay may enter into in the future,
or otherwise.
 
  Greater Bay has, through the Guarantee, the Guarantee Agreement, the Trust
Agreement, the Junior Subordinated Debentures, the Indenture and the Expense
Agreement, taken together, fully, irrevocably and unconditionally guaranteed
all of GBB Capital's obligations under the Trust Preferred Securities. No
single document standing alone or operating in conjunction with fewer than all
of the other documents constitutes such guarantee. It is only the combined
operation of these documents that has the effect of providing a full,
irrevocable and unconditional guarantee of GBB Capital's obligations under the
Trust Preferred Securities. See "Relationship Among the Trust Preferred
Securities, the Junior Subordinated Debentures and the Guarantee."
 
STATUS OF THE GUARANTEE
 
  The Guarantee will constitute an unsecured obligation of Greater Bay and
will rank subordinate and junior in right of payment to all Senior and
Subordinated Debt in the same manner as the Junior Subordinated Debentures.
 
  The Guarantee will constitute a guarantee of payment and not of collection.
For example, the guaranteed party may institute a legal proceeding directly
against Greater Bay to enforce its rights under the Guarantee without first
instituting a legal proceeding against any other person or entity. The
Guarantee will be held for the benefit of the holders of the Trust Preferred
Securities. The Guarantee will not be discharged except by payment of the
Guarantee Payments in full to the extent not paid by GBB Capital or upon
distribution to the holders of the Trust Preferred Securities of the Junior
Subordinated Debentures to the holders of the Trust Preferred Securities. The
Guarantee does not place a limitation on the amount of additional Senior and
Subordinated Debt that may be incurred by Greater Bay. Greater Bay expects
from time to time to incur additional indebtedness constituting Senior and
Subordinated Debt.
 
AMENDMENTS AND ASSIGNMENT
 
  Except with respect to any changes which do not materially adversely affect
the rights of holders of the Trust Preferred Securities (in which case no vote
will be required), the Guarantee Agreement may not be amended without the
prior approval of the holders of not less than a majority of the aggregate
Liquidation Amount of such outstanding Trust Preferred Securities. See
"Description of the Trust Preferred Securities--Voting Rights; Amendment of
the Trust Agreement." All guarantees and agreements contained in the Guarantee
Agreement shall bind the successors, assigns, receivers, trustees and
representatives of Greater Bay and shall inure to the benefit of the holders
of the Trust Preferred Securities then outstanding.
 
EVENTS OF DEFAULT
 
  An event of default under the Guarantee Agreement will occur upon the
failure of Greater Bay to perform any of its payment or other obligations
thereunder. The holders of not less than a majority in aggregate Liquidation
Amount of the Trust Preferred Securities have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Guarantee Trustee in respect of the Guarantee or to
 
                                      91
<PAGE>
 
direct the exercise of any trust or power conferred upon the Guarantee Trustee
under the Guarantee Agreement. Any holder of the Trust Preferred Securities
may institute a legal proceeding directly against Greater Bay to enforce its
rights under the Guarantee without first instituting a legal proceeding
against GBB Capital, the Guarantee Trustee or any other person or entity.
 
  Greater Bay, as guarantor, is required to file annually with the Guarantee
Trustee a certificate as to whether or not Greater Bay is in compliance with
all the conditions and covenants applicable to it under the Guarantee
Agreement.
 
INFORMATION CONCERNING THE GUARANTEE TRUSTEE
 
  The Guarantee Trustee, other than during the occurrence and continuance of a
default by Greater Bay in performance of the Guarantee, undertakes to perform
only such duties as are specifically set forth in the Guarantee Agreement and,
after default with respect to the Guarantee, must exercise the same degree of
care and skill as a prudent person would exercise or use in the conduct of his
or her own affairs. Subject to this provision, the Guarantee Trustee is under
no obligation to exercise any of the powers vested in it by the Guarantee
Agreement at the request of any holder of the Trust Preferred Securities
unless it is offered reasonable indemnity against the costs, expenses and
liabilities that might be incurred thereby.
 
TERMINATION OF THE GUARANTEE
 
  The Guarantee will terminate and be of no further force and effect upon full
payment of the Redemption Price of the Trust Preferred Securities, upon full
payment of the amounts payable upon liquidation of GBB Capital or upon
distribution of Junior Subordinated Debentures to the holders of the Trust
Preferred Securities. The Guarantee will continue to be effective or will be
reinstated, as the case may be, if at any time any holder of the Trust
Preferred Securities must restore payment of any sums paid under the Trust
Preferred Securities or the Guarantee.
 
GOVERNING LAW
 
  The Guarantee Agreement will be governed by and construed in accordance with
the laws of the State of California.
 
THE EXPENSE AGREEMENT
 
  Pursuant to the Expense Agreement entered into by Greater Bay under the
Trust Agreement, Greater Bay will irrevocably and unconditionally guarantee to
each person or entity to whom GBB Capital becomes indebted or liable, the full
payment of any costs, expenses or liabilities of GBB Capital, other than
obligations of GBB Capital to pay to the holders of the Trust Preferred
Securities or other similar interests in GBB Capital of the amounts due such
holders pursuant to the terms of the Trust Preferred Securities or such other
similar interests, as the case may be.
 
            RELATIONSHIP AMONG THE TRUST PREFERRED SECURITIES, THE
               JUNIOR SUBORDINATED DEBENTURES AND THE GUARANTEE
 
FULL AND UNCONDITIONAL GUARANTEE
 
  Payments of Distributions and other amounts due on the Trust Preferred
Securities (to the extent GBB Capital has funds available for the payment of
such Distributions) are irrevocably guaranteed by Greater Bay as and to the
extent set forth under "Description of Guarantee." Taken together, Greater
Bay's obligations under the Junior Subordinated Debentures, the Indenture, the
Trust Agreement, the Expense Agreement, the Guarantee Agreement and the
Guarantee provide, in the aggregate, a full, irrevocable and unconditional
guarantee of payments of distributions and other amounts due on the Trust
Preferred Securities. No single document standing alone or operating in
conjunction with fewer than all of the other documents constitutes such
guarantee. It is
 
                                      92
<PAGE>
 
only the combined operation of those documents that has the effect of
providing a full, irrevocable and unconditional guarantee of GBB Capital's
obligations under the Trust Preferred Securities. If and to the extent that
Greater Bay does not make payments on the Junior Subordinated Debentures, GBB
Capital will not pay Distributions or other amounts due on the Trust Preferred
Securities. The Guarantee does not cover payment of Distributions when GBB
Capital does not have sufficient funds to pay such Distributions. In such
event, the remedy of a holder of the Trust Preferred Securities is to
institute a legal proceeding directly against Greater Bay for enforcement of
payment of such Distributions to such holder. The obligations of Greater Bay
under the Guarantee are subordinate and junior in right of payment to all
Senior and Subordinated Debt.
 
SUFFICIENCY OF PAYMENTS
 
  As long as payments of interest and other payments are made when due on the
Junior Subordinated Debentures, such payments will be sufficient to cover
Distributions and other payments due on the Trust Preferred Securities,
primarily because: (i) the aggregate principal amount of the Junior
Subordinated Debentures will be equal to the sum of the aggregate Liquidation
Amount of the Trust Preferred Securities and Common Securities; (ii) the
interest rate and interest and other payment dates on the Junior Subordinated
Debentures will match the Distribution rate and Distribution and other payment
dates for the Trust Preferred Securities; (iii) Greater Bay shall pay for all
and any costs, expenses and liabilities of GBB Capital except GBB Capital's
obligations to holders of Trust Preferred Securities; and (iv) the Trust
Agreement further provides that GBB Capital will not engage in any activity
that is not consistent with its limited purposes.
 
  Notwithstanding anything to the contrary in the Indenture, Greater Bay has
the right to set-off any payment it is otherwise required to make thereunder
with and to the extent Greater Bay has theretofore made, or is concurrently on
the date of such payment making, a payment under the Guarantee.
 
ENFORCEMENT RIGHTS OF HOLDERS OF THE TRUST PREFERRED SECURITIES UNDER THE
GUARANTEE
 
  A holder of any the Trust Preferred Securities may institute a legal
proceeding directly against Greater Bay to enforce its rights under the
Guarantee without first instituting a legal proceeding against the Guarantee
Trustee, GBB Capital or any other person or entity.
 
  A default or event of default under any Senior and Subordinated Debt would
not constitute a default or Event of Default. However, in the event of payment
defaults under, or acceleration of, Senior and Subordinated Debt, the
subordination provisions of the Indenture provide that no payments may be made
in respect of the Junior Subordinated Debentures until such Senior and
Subordinated Debt has been paid in full or any payment default thereunder has
been cured or waived. Failure to make required payments on Junior Subordinated
Debentures would constitute an Event of Default.
 
LIMITED PURPOSE OF GBB CAPITAL
 
  The Trust Preferred Securities evidence a beneficial interest in GBB
Capital, and GBB Capital exists for the sole purpose of issuing the Trust
Securities and investing the proceeds thereof in Junior Subordinated
Debentures. A principal difference between the rights of a holder of the Trust
Preferred Securities and a holder of a Junior Subordinated Debenture is that a
holder of a Junior Subordinated Debenture is entitled to receive from Greater
Bay the principal amount of and interest accrued on Junior Subordinated
Debentures held, while a holder of the Trust Preferred Securities is entitled
to receive Distributions from GBB Capital (or from Greater Bay under the
Guarantee) if and to the extent GBB Capital has funds available for the
payment of such Distributions.
 
RIGHTS UPON TERMINATION
 
  Upon any voluntary or involuntary termination, winding-up or liquidation of
GBB Capital involving the liquidation of the Junior Subordinated Debentures,
the holders of Trust Preferred Securities will be entitled to receive, out of
assets held by GBB Capital, the Liquidation Distribution in cash. See
"Description of the Trust Preferred Securities--Liquidation Distribution Upon
Termination." Upon any voluntary or involuntary
 
                                      93
<PAGE>
 
liquidation or bankruptcy of Greater Bay, the Property Trustee, as holder of
the Junior Subordinated Debentures, would be a subordinated creditor of
Greater Bay, subordinated in right of payment to all Senior and Subordinated
Debt as set forth in the Indenture, but entitled to receive payment in full of
principal and interest, before any stockholders of Greater Bay receive
payments or distributions. Since Greater Bay is the guarantor under the
Guarantee and has agreed to pay for all costs, expenses and liabilities of GBB
Capital (other than GBB Capital's obligations to the holders of its Trust
Preferred Securities), the positions of a holder of the Trust Preferred
Securities and a holder of Junior Subordinated Debentures relative to other
creditors and to stockholders of Greater Bay in the event of liquidation or
bankruptcy of Greater Bay are expected to be substantially the same.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  In the opinion of Manatt, Phelps & Phillips, LLP, counsel to the Company
("Counsel"), the following summary accurately describes the material United
States federal income tax consequences that may be relevant to the purchase,
ownership and disposition of Trust Preferred Securities. Unless otherwise
stated, this summary deals only with Trust Preferred Securities held as
capital assets by United States Persons (defined below) who purchase the Trust
Preferred Securities upon original issuance at their original offering price.
As used herein, a "United States Person" means a person that is (i) a citizen
or resident of the United States, (ii) a corporation, partnership or other
entity created or organized in or under the laws of the United States or any
political subdivision thereof, (iii) an estate the income of which is subject
to United States federal income taxation regardless of its source, or (iv) a
trust the income of which is subject to United States federal income taxation
regardless of its source; provided, however, that for taxable years beginning
after December 31, 1996 (or, if a trustee so elects, for taxable years ending
after August 20, 1996), a "United States Person" shall include any trust if a
court is able to exercise primary supervision over the administration of such
trust and one or more United States fiduciaries have the authority to control
all substantial decisions of such trust. The tax treatment of holders may vary
depending on their particular situation. This summary does not address all the
tax consequences that may be relevant to a particular holder or to holders who
may be subject to special tax treatment, such as banks, real estate investment
trusts, regulated investment companies, insurance companies, dealers in
securities or currencies, tax-exempt investors, or foreign investors. In
addition, this summary does not include any description of any alternative
minimum tax consequences or the tax laws of any state, local or foreign
government that may be applicable to a holder of Trust Preferred Securities.
This summary is based on the Internal Revenue Code of 1986, as amended (the
"Code"), the Treasury regulations promulgated thereunder and administrative
and judicial interpretations thereof, as of the date hereof, all of which are
subject to change, possibly on a retroactive basis.
 
  The following discussion does not discuss the tax consequences that might be
relevant to persons that are not United States Persons ("non-United States
Persons"). Non-United States Persons should consult their own tax advisors as
to the specific United States federal income tax consequences of the purchase,
ownership and disposition of Trust Preferred Securities.
 
  The authorities on which this summary is based are subject to various
interpretations and the opinions of Counsel are not binding on the Internal
Revenue Service ("Service") or the courts, either of which could take a
contrary position. Moreover, no rulings have been or will be sought from the
Service with respect to the transactions described herein. Accordingly, there
can be no assurance that the Service will not challenge the opinions expressed
herein or that a court would not sustain such a challenge. Nevertheless,
Counsel has advised that it is of the view that, if challenged, the opinions
expressed herein would be sustained by a court with jurisdiction in a properly
presented case.
 
  Holders should consult their own tax advisors with respect to the tax
consequences to them of the purchase, ownership and disposition of the Trust
Preferred Securities, including the tax consequences under state, local,
foreign, and other tax laws and the possible effects of changes in united
states federal or other tax laws. For a discussion of the possible redemption
of the Trust Preferred Securities upon the occurrence of certain tax events,
see "Description of the Trust Preferred Securities--Redemption."

CLASSIFICATION OF GBB CAPITAL
 
  In connection with the issuance of the Trust Preferred Securities, Counsel
is of the opinion that, under current law and assuming compliance with the
terms of the Trust Agreement, and based on certain facts and assumptions
contained in such opinion, GBB Capital will be classified as a grantor trust
and not as an association taxable as a corporation for United States federal
income tax purposes. As a result, each beneficial owner of the Trust Preferred
Securities (a "Securityholder") will be treated as owning an undivided
beneficial interest in the Junior Subordinated Debentures. Accordingly, each
Securityholder will be required to include in its gross income its pro rata
share of the interest income or original issue discount that is paid or
accrued on the Junior Subordinated Debentures. See "--Interest Income and
Original Issue Discount" herein. No amount included in income with respect to
the Trust Preferred Securities will be eligible for the dividends received
deduction.
 
CLASSIFICATION OF THE JUNIOR SUBORDINATED DEBENTURES
 
  The Company intends to take the position that the Junior Subordinated
Debentures will be classified for United States federal income tax purposes as
indebtedness of the Company under current law, and, by acceptance of a Trust
Preferred Security, each holder covenants to treat the Junior Subordinated
Debentures as indebtedness and the Trust Preferred Securities as evidence of
an indirect beneficial ownership interest in the Junior Subordinated
Debentures. No assurance can be given, however, that such position of the
Company will not be challenged by the Internal Revenue Service or, if
challenged, that such a challenge will not be successful. The remainder of
this discussion assumes that the Junior Subordinated Debentures will be
classified for United States federal income tax purposes as indebtedness of
the Company. See "Risk Factors--Uncertainty of Deductibility of Interest on
the Junior Subordinated Debentures."
 
INTEREST INCOME AND ORIGINAL ISSUE DISCOUNT
 
  Except as set forth below, stated interest on the Junior Subordinated
Debentures generally will be included in income by a Securityholder at the
time such interest income is paid or accrued in accordance with such
Securityholder's regular method of tax accounting.
 
  Greater Bay believes that, under the applicable Treasury regulations, the
Junior Subordinated Debentures will not be considered to have been issued with
"original issue discount" ("OID") within the meaning of Section 1273(a) of the
Code. If, however, Greater Bay exercises its right to defer Payments of
interest on the Junior Subordinated Debentures, the Junior Subordinated
Debentures will become OID instruments at such time and all Securityholders
will be required to accrue the stated interest on the Junior Subordinated
Debentures on a daily basis during the Extension Period, even though Greater
Bay will not pay such interest until the end of the Extension Period, and even
though some Securityholders may use the cash method of tax accounting.
Moreover, thereafter the Junior Subordinated Debentures will be taxed as OID
instruments for as long as they remain outstanding. Thus, even after the end
of the Extension Period, all Securityholders would be required to continue to
include the stated interest on the Junior Subordinated Debentures in income on
a daily economic accrual basis, regardless of their method of tax accounting
and in advance of receipt of the cash attributable to such interest income.
Under the OID economic accrual rules, a Securityholder would accrue an amount
of interest income each year that approximates the stated interest payments
called for under the Junior Subordinated Debentures, and actual cash payments
of interest on the Junior Subordinated Debentures would not be reported
separately as taxable income.
 
  The Treasury regulations described above have not yet been addressed in any
rulings or other interpretations by the Service, and it is possible that the
Service could take a contrary position. If the Service were to assert
successfully that the stated interest on the Junior Subordinated Debentures
was OID regardless of whether Greater Bay exercises its right to defer
payments of interest on such debentures, all Securityholders would be required
to include such stated interest in income on a daily economic accrual basis as
described above.

DISTRIBUTION OF JUNIOR SUBORDINATED DEBENTURES TO HOLDERS OF TRUST PREFERRED
SECURITIES
 
  Under current law, a distribution by GBB Capital of the Junior Subordinated
Debentures as described under the caption "Description of the Trust Preferred
Securities--Liquidation Distribution Upon Termination" will be non-taxable and
will result in the Securityholder receiving directly its pro rata share of the
Junior Subordinated Debentures previously held indirectly through GBB Capital,
with a holding period and aggregate tax basis equal to the holding period and
aggregate tax basis such Securityholder had in its Trust Preferred Securities
before such distribution. If, however, the liquidation of GBB Capital were to
occur because GBB Capital is subject to United States federal income tax with
respect to income accrued or received on the Junior Subordinated Debentures as
a result of a Tax Event or otherwise, the distribution of Junior Subordinated
Debentures to Securityholders by GBB Capital could be a taxable event to GBB
Capital and each Securityholder, and a Securityholder would recognize gain or
loss as if the Securityholder had exchanged its Trust Preferred Securities for
the Junior Subordinated Debentures it received upon the liquidation of GBB
Capital. A Securityholder would recognize interest income in respect of Junior
Subordinated Debentures received from GBB Capital in the manner described
above under "--Interest Income and Original Issue Discount" herein.
 
SALES OR REDEMPTION OF TRUST PREFERRED SECURITIES
 
  Gain or loss will be recognized by a Securityholder on a sale of Trust
Preferred Securities (including a redemption for cash) in an amount equal to
the difference between the amount realized (which for this purpose, will
exclude amounts attributable to accrued interest or OID not previously
included in income) and the Securityholder's adjusted tax basis in the Trust
Preferred Securities sold or so redeemed. Gain or loss recognized by a
Securityholder on Trust Preferred Securities held for more than one year will
generally be taxable as long-term capital gain or loss. Amounts attributable
to accrued interest with respect to a Securityholder's pro rata share of the
Junior Subordinated Debentures not previously included in income will be
taxable as ordinary income.
 
BACKUP WITHHOLDING TAX AND INFORMATION REPORTING
 
  The amount of OID accrued on the Trust Preferred Securities held of record
by United States Persons (other than corporations and other exempt
Securityholders), if any, will be reported to the Service. "Backup"
withholding at a rate of 31% will apply to payments of interest to non-exempt
United States Persons unless the Securityholder furnishes its taxpayer
identification number in the manner prescribed in applicable Treasury
Regulations, certifies that such number is correct, certifies as to no loss of

POSSIBLE TAX LAW CHANGES AFFECTING THE TRUST PREFERRED SECURITIES
 
  Recently the Clinton Administration announced its budget proposals for the
fiscal year 1998. That announcement included a proposal that could affect the
tax characteristics of the Junior Subordinated Debentures. Under the
Administration's proposal, no deduction would be allowed for interest or
original issue discount on an instrument issued by a corporation that has a
maximum term of more than 40 years, or is payable in stock of the issuer or a
related party. The budget announcement also states that no such deduction
would be allowed for certain indebtedness that is reflected as equity on the
issuer's balance sheet. The budget announcement states that the effective date
of the first proposal is for instruments issued "after the date of first
committee action," which is not a legally precise term. The budget
announcement is less clear about the proposed effective date of the second
proposal mentioned above.
 
  Similar proposals were made by the Administration last year. The Revenue
Reconciliation Bill of 1996 (the "1996 Bill") would, among other things, have
denied interest deductions for interest on an instrument, issued by a
corporation, that had a maximum term of more than 20 years and that was not
shown as indebtedness on the separate balance sheet of the issuer or, where
the instrument was issued to a related party (other than a
 
                                      96
<PAGE>
 
corporation), where the holder or some other related party issued a related
instrument that is not shown as indebtedness on the issuer's consolidated
balance sheet. The 1996 Bill was never enacted, but it is likely that the
second proposal in the budget announcement mentioned above will be similar in
some respects to the proposal in the 1996 Bill. Enactment of this proposal
could affect deduction of interest expenses and original issue discount with
respect to the Junior Subordinated Debentures. This, in turn, could create a
Tax Event affecting the Trust Preferred Securities.
 
  In connection with the 1996 Bill, the Chairmen of the Senate Finance and
House Ways and Means Committees issued a joint statement that it was their
intention that the effective date of the Administration's legislative
proposals, if adopted, would be no earlier than the date of appropriate
Congressional action. Senate Finance Committee Chairman William Roth has been
quoted in the news media recently as stating that the 1997 tax changes
generally should be effective on a prospective basis.
 
  It is intended that the Trust Preferred Securities and the Junior
Subordinated Debentures will be issued prior to any type of Congressional
committee action with respect to the aforementioned budget proposal. However,
due to business considerations, the unpredictability of when Congress will
begin action with respect to the Administration's proposals, and the
imprecision in the public statements concerning the anticipated effective date
of the legislative proposals, there can be no guarantee that these instruments
will not be affected by the aforementioned legislative proposals, if they are
enacted.
 
  There also can be no assurance that other future legislative proposals or
final legislation will not affect the ability of the Company to deduct
interest on the Junior Subordinated Debentures. Such a change could give rise
to a Tax Event, which may permit Greater Bay, upon approval of the Federal
Reserve, if then required under applicable capital guidelines or policies of
the Federal Reserve, to cause a redemption of the Trust Preferred Securities.
See "Description of the Trust Preferred Securities--Redemption--Tax Event
Redemption" and "Description of Junior Subordinated Debentures--Redemption."
 
               DESCRIPTION OF GREATER BAY BANCORP CAPITAL STOCK
 
  The authorized capital stock of Greater Bay consists of 6,000,000 shares of
common stock, no par value ("Common Stock"), and 4,000,000 shares of preferred
stock, no par value ("Preferred Stock"). As of December 31, 1996, 3,238,887
shares of Common Stock were outstanding. No shares of Preferred Stock are
outstanding.
 
COMMON STOCK
 
  Each share of Common Stock is entitled to participate pro rata in
distributions upon liquidation. Holders of Common Stock may receive dividends
as declared by the Board of Directors out of funds legally available therefor.
Holders of Common Stock have no preemptive, subscription, conversion,
redemption or similar rights. All outstanding shares of Common Stock have
voting power to approve mergers, sales of substantially all of Greater Bay's
assets and similar material corporate transactions. Holders of Common Stock
are entitled to one vote for each share of Common Stock they hold on all
matters submitted to a vote of shareholders, except that for the election of
directors each shareholder has cumulative voting rights and is entitled to as
many votes as shall equal the number of shares held by such shareholder
multiplied by the number of directors to be elected, and such shareholder may
cast all his or her votes for a single candidate or distribute such votes
among any or all of the candidates (that is, to cast for any candidate a
number of votes greater than the number of shares of stock held by such
shareholder) unless such candidate's name has been placed in nomination prior
to the voting and the shareholder has given notice at the meeting prior to the
voting of the shareholder's intention to cumulate votes. The rights,
privileges and preferences of the holders of Common Stock are subject to the
rights of the holders of any Preferred Stock that may be designated and issued
by Greater Bay in the future.
 
 
                                      97
<PAGE>
 
PREFERRED STOCK
 
  The Greater Bay Board of Directors has the authority, without further
shareholder action, to issue from time to time a maximum of 4,000,000 shares
of Preferred Stock in one or more series and with such terms and at such times
and for such consideration as the Board of Directors may determine. The
authority of the Board of Directors includes the determination or fixing of
the following with respect to shares of such class or any series thereof: (i)
the number of shares and designation or title thereof; (ii) rights as to
dividends; (iii) whether and upon what terms, including sinking funds, the
shares are to be redeemable; (iv) whether and upon what terms, the shares are
convertible; (v) the voting rights, if any, which shall apply; provided,
however, that in no event shall any holder of any series of the Preferred
Stock be entitled to more than one vote for each share of Preferred Stock held
by such holder; and (vi) the rights of the holders upon the dissolution, or
upon the distribution of assets, of Greater Bay. Any shares of Preferred Stock
which may be issued may rank prior to the Common Stock as to payment of
dividends and upon liquidation. No Preferred Stock is currently outstanding.

  Piper Jaffray Inc. (the "Underwriter"), has agreed, subject to the terms and
conditions of a Purchase Agreement to be entered into by the Underwriter,

reallow a concession not in excess of $       per Trust Preferred Security to
certain other brokers and dealers. After the public offering, the public
offering price, concession and reallowance, and other selling terms may be
changed by the Underwriter.
 
  In view of the fact that the proceeds from the sale of the Trust Preferred
Securities will be used to purchase the Junior Subordinated Debentures issued

compensation for the Underwriter's arranging the investment therein of such
proceeds an amount of $       per Trust Preferred Security.
 
  Each of Greater Bay and GBB Capital has agreed to indemnify the Underwriter
and its controlling persons against certain liabilities, including liabilities
under the Securities Act of 1933, as amended, or to contribute to payments the

to any account over which it exercises discretionary authority in excess of 5%
of the number of Trust Preferred Securities offered hereby.

Preferred Securities, the enforceability of the Trust Agreement and the

                             AVAILABLE INFORMATION
 
  Greater Bay and GBB Capital have jointly filed with the Commission a
Registration Statement on Form S-1 (together with all amendments and exhibits
thereto the "Registration Statement") under the Securities Act, with respect
to the offering of the securities offered hereby. This Prospectus does not
contain all of the information set forth in the Registration Statement,
certain parts of which are omitted in accordance with the rules and

regulations of the Commission. For further information with respect to the
Company, GBB Capital and the securities offered hereby, reference is made to
the Registration Statement and the exhibits and the financial statements, notes
and schedules filed as a part thereof or incorporated by reference therein,
which may be inspected at the public reference facilities of the Commission, at
the addresses set forth below. Statements made in this Prospectus concerning
the contents of any documents referred to herein are not necessarily complete,
and in each instance are qualified in all respects by reference to the copy of
such document filed as an exhibit to the Registration Statement.
 
  Greater Bay is subject to the informational requirements of the Exchange Act,
and in accordance therewith files reports, proxy statements and other
information with the Commission. Reports, proxy statements and other
information filed by Greater Bay (and its predecessors, Mid-Peninsula Bancorp
and Cupertino National Bancorp) can be inspected and copies of such material

any activity other than holding as trust assets the Junior Subordinated
Debentures of Greater Bay and issuing the Trust Securities. See "Prospectus

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
The Board of Directors and Shareholders
Greater Bay Bancorp:
 
  We have audited the accompanying consolidated balance sheets of Greater Bay
Bancorp (formerly Mid-Peninsula Bancorp) and subsidiaries (the Company) as of
December 31, 1996 and 1995, and the related consolidated statements of
operations, changes in shareholders' equity, and cash flows for each of the
years in the three-year period ended December 31, 1996. These consolidated
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, based on our audits, the consolidated financial statements
referred to above present fairly, in all material respects, the financial
position of the Company as of December 31, 1996 and 1995, and the results of
its operations and its cash flows for each of the years in the three-year
period ended December 31, 1996, in conformity with generally accepted
accounting principles.

                 YEARS ENDED DECEMBER 31, 1996, 1995, AND 1994
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  ORGANIZATION AND NATURE OF OPERATIONS
 
  Greater Bay Bancorp ("GBB" or the "Company") is a California corporation and
bank holding company that was incorporated on November 14, 1984 as San Mateo
County Bancorp. The name was changed to Mid-Peninsula Bancorp on October 7,
1994 as a result of the merger between Mid-Peninsula Bank and San Mateo County
Bancorp and its wholly owned subsidiary, WestCal National Bank. The name was
further changed to Greater Bay Bancorp on November 27, 1996 as a result of the
merger between Mid-Peninsula Bancorp and Cupertino National Bancorp (see Note
2). Upon consummation of the merger with Cupertino National Bancorp, GBB
became a multi-bank holding company of two wholly owned bank subsidiaries,
Mid-Peninsula Bank ("MPB") and Cupertino National Bank & Trust ("CNB"),
collectively the "Banks". MPB commenced operations in October 1987 and is a
state chartered bank regulated by the Federal Reserve Bank (FRB) and the
California State Banking Department. CNB commenced operations in May 1985 and
is a national banking association regulated by the Office of the Comptroller
of Currency (OCC).
 
  The Company provides a wide range of commercial banking services to small
and medium-sized businesses, real estate developers and property managers,
business executives, professionals and other individuals. The Company operates
through seven regional offices in Cupertino, Palo Alto, San Mateo, San Carlos
and San Jose, California.
 
  CONSOLIDATION AND BASIS OF PRESENTATION
 
  The consolidated financial statements include the accounts of GBB and its
wholly-owned subsidiaries, CNB and MPB. All significant intercompany
transactions and balances have been eliminated. Certain reclassifications have
been made to prior years' consolidated financial statements to conform to the
1996 presentation. The accounting and reporting policies of the Company
conform to generally accepted accounting principles and to prevailing
practices within the banking industry.
 
  USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of certain assets and liabilities
and disclosure of contingent assets and liabilities at the date of the
financial statements and the reported amounts of certain revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
  CASH AND CASH EQUIVALENTS
 
  For purposes of reporting cash flows, cash and cash equivalents include cash
on hand, amounts due from banks and federal funds sold. Generally, federal
funds are sold for one-day periods. CNB and MPB are required by the Federal
Reserve System to maintain non-interest earning cash reserves against certain
of their deposit accounts. At December 31, 1996, the required combined
reserves totaled approximately $2.9 million.
 
  INVESTMENT SECURITIES
 
  Statement of Financial Accounting Standards ("SFAS") No. 115, "Accounting
for Certain Investments in Debt and Equity Securities", which was adopted by
the Company in 1994, requires that investment securities be classified into
three portfolios, and be accounted for as follows: 1) debt and equity
securities for which the Company has the positive intent and ability to hold
to maturity are classified as held-to-maturity and reported at
 
                                      F-7
<PAGE>
 
                     GREATER BAY BANCORP AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
amortized cost; 2) debt and equity securities that are bought and held
principally for the purpose of selling in the near term are classified as
trading securities and reported at fair value, with unrealized gains and
losses included in earnings; and 3) debt and equity securities not classified
as either held-to-maturity or trading securities are classified as available-
for-sale securities and reported at fair value, with unrealized gains and
losses excluded from earnings and reported as a separate component of
shareholders' equity.
 
  A decline in the market value of any available-for-sale or held-to-maturity
security below cost that is deemed other than temporary, results in a charge
to earnings and the corresponding establishment of a new cost basis for the
security.
 
  Premiums and discounts are amortized or accreted over the life of the
related security as an adjustment to yield using the effective interest
method. Dividend and interest income are recognized when earned. Realized
gains and losses for securities classified as available-for-sale and held-to-
maturity are included in earnings and are derived using the specific
identification method for determining the cost of securities sold.
 
  The required investment of 3% of capital stock and surplus in Federal
Reserve Bank stock, for both MPB and CNB, is recorded at cost.
 
  LOANS
 
  Loans held for investment are carried at amortized cost. The Company's loan
portfolio consists primarily of commercial and real estate loans generally
collateralized by first and second deeds of trust on real estate as well as
business assets and personal property.
 
  Interest income is accrued on the outstanding loan balances using the simple
interest method. Loans are generally placed on nonaccrual status when the
borrowers are past due 90 days and when full payment of principal or interest
is not expected. At the time a loan is placed on nonaccrual status, any
interest income previously accrued but not collected is reversed. Interest
accruals are resumed on such loans only when they are brought fully current
with respect to interest and principal and when, in the judgment of
management, the loans are estimated to be fully collectible as to both
principal and interest.
 
  The Company charges loan origination and commitment fees. Net loan
origination fees and costs are deferred and amortized to interest income over
the life of the loan, using the effective interest method. Loan commitment
fees are amortized to interest income over the commitment period.
 
  SALES AND SERVICING OF SMALL BUSINESS ADMINISTRATION ("SBA") LOANS
 
  The Company originates loans to customers under SBA programs that generally
provide for SBA guarantees of 70% to 90% of each loan. The Company generally
sells the guaranteed portion of each loan to an investor and retains the
unguaranteed portion and servicing rights in its own portfolio. Funding for
the SBA programs depend on annual appropriations by the U.S. Congress.
 
  Gains on these sales are earned through the sale of the guaranteed portion
of the loan for an amount in excess of the adjusted carrying value of the
portion of the loan sold. The Company allocates the carrying value of such
loans between the portion sold, the portion retained and a value assigned to
the right to service the loan. The difference between the adjusted carrying
value of the portion retained and the face amount of the portion retained is
amortized to interest income over the life of the related loan using a method
which approximates the interest method. The value assigned to the right to
service is also amortized over the estimated life of the loan.
 
  ALLOWANCE FOR LOAN LOSSES
 
  The Company adopted SFAS No. 114, Accounting by Creditors for Impairment of
a Loan, as amended by SFAS No. 118, on January 1, 1995. Under these standards,
a loan is considered impaired, based on current
 
                                      F-8
<PAGE>
 
                     GREATER BAY BANCORP AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
information and events, if it is probable that the Company will be unable to
collect the scheduled payments of principal and interest when due according to
the contractual terms of the loan agreement. Under these standards, any
allowance on impaired loans is generally based on one of three methods. It
requires that impaired loans be measured at either, (1) the present value of
expected cash flows at the loan's effective interest rate, (2) the loan's
observable market price, or (3) the fair market value of the collateral of the
loan. In general, these statements are not applicable to large groups of
smaller-balance loans that are collectively evaluated for impairment such as
credit cards, residential mortgage and/or consumer installment loans. Adoption
of SFAS No. 114 and No. 118 did not have a material effect on the financial
statements of the Company in 1995. Income recognition on impaired loans
conforms to the method the Company uses for income recognition on nonaccrual
loans.
 
  The allowance for loan losses is maintained at a level deemed appropriate by
management to adequately provide for known and unidentified losses in the loan
portfolio. The allowance is based upon a number of factors, including
prevailing and anticipated economic trends, industry experience, industry and
geographic concentrations, estimated collateral values, management's
assessment of credit risk inherent in the portfolio, delinquency trends,
historical loss experience, specific problem loans and other relevant factors.
Additions to the allowance, in the form of provisions, are reflected in
current operating results, while charge-offs to the allowance are made when a
loss is determined to have occurred. Because the allowance for loan losses is
based on estimates, ultimate losses may vary from the current estimates.
 
  When a loan is sold, unamortized fees and capitalized direct costs are
recognized in the consolidated statements of operations. Other loan fees and
charges representing service costs for the repayment of loans, for delinquent
payments or for miscellaneous loan services are recognized when earned.
 
  OTHER REAL ESTATE OWNED
 
  Other real estate owned (OREO) consists of properties acquired through
foreclosure and is stated at the lower of cost or fair value less estimated
costs to sell. Development and improvement costs relating to the property are
capitalized. Estimated losses that result from the ongoing periodic valuation
of these properties are charged to current earnings with a provision for
losses on foreclosed property in the period in which they are identified. The
resulting allowance for OREO losses is decreased when the property is sold.
Operating expenses of such properties, net of related income, are included in
other expenses. Gains and losses on disposition of OREO are included in other
income.
 
  PREMISES AND EQUIPMENT
 
  Premises and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation and amortization are computed on a straight-line
basis over the shorter of the lease terms or estimated useful lives of the
assets, which are generally 3 to 10 years.
 
  INCOME TAXES
 
  Deferred income taxes reflect the estimated future tax effects of temporary
differences between the amount of assets and liabilities for financial
reporting purposes and such amounts as measured by tax laws and regulations.
 
  PER SHARE DATA
 
  Net income per common and common equivalent share is based on the weighted
average number of shares of common stock outstanding during the year plus the
effect of dilutive stock options. All years presented include the effect of
stock dividends declared in 1995 and 1994. The weighted average common and
common equivalent shares outstanding for 1996, 1995 and 1994 were 3,359,700;
3,144,550 and 3,001,211, respectively.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Fully diluted earnings per share were approximately equal to primary
earnings per share in each of the years in the three-year period ended
December 31, 1996.
 
  Weighted average shares outstanding and all per share amounts included in
the consolidated financial statements and notes thereto are based upon the
increased number of shares giving retroactive effect to the 1994 merger with
San Mateo County Bancorp at a 1.0617 conversion ratio, and the 1996 merger
with Cupertino National Bancorp at a 0.81522 conversion ratio.
 
NOTE 2--MERGERS
 
  On November 27, 1996, the Company consummated a merger between Mid-Peninsula
Bancorp and Cupertino National Bancorp. As discussed in Note 1, concurrently
with the merger the name of the holding company was changed to Greater Bay
Bancorp. Following the terms of the merger agreement, the Company issued
approximately 1,586,000 shares of its common stock in exchange for the
outstanding common stock of Cupertino National Bancorp at an exchange ratio of
0.81522 of the Company's common stock for each share of Cupertino National
Bancorp's common stock. The merger has been accounted for as a pooling of
interests business combination and, accordingly, the consolidated financial
statements and the financial data for the periods prior to the merger have
been restated to include the accounts and results of operations of Cupertino
National Bancorp.
 
  On October 7, 1994, San Mateo County Bancorp's wholly owned subsidiary,
WestCal National Bank, was merged with and into Mid-Peninsula Bank, and San
Mateo County Bancorp concurrently changed its name to Mid-Peninsula Bancorp.
The merger was accounted for as a pooling of interests. All periods have been
restated to reflect the results of the combination. The accompanying
consolidated financial statements reflect the issuance of the Company's common
stock in exchange for all of MPB's common stock outstanding as of October 7,
1994, based upon the exchange ratio of 1.0617 shares of the Company's common
stock for each share of MPB's common stock.
 
  In both mergers, certain reclassifications have been made to conform to the
Company's presentation. The results of operations previously reported by the
separate enterprises for the period before the merger was consummated and that
are included in the current combined amounts presented in the accompanying
consolidated financial statements are summarized below:

  In November 1995, the FASB issued a special report, "A Guide to
Implementation of Statement No. 115, on Accounting for Certain Investments in
Debt and Equity Securities--Questions and Answers" (the "Special Report"). The
Special Report allowed companies to reassess the appropriateness of the
classifications of all securities held and account for any resulting
reclassifications at fair value. Reclassifications from this one-time
reassessment will not call into question the intent of an enterprise to hold
other debt securities to maturity in the future, provided that
reclassification was performed by December 31, 1995. The Company adopted the
reclassification provision of the Special Report prior to December 31, 1995
and transferred $36.4 million of held-to-maturity securities into the
available-for-sale category. The unrealized pretax gain upon transfer was
$512,000 as of December 31, 1995.

NOTE 11--EMPLOYEE BENEFIT PLANS
 
  STOCK OPTIONS PLANS
 
  Effective November 27, 1996, the Company's shareholders approved the Greater
Bay Bancorp 1996 Stock Option Plan ("the Bancorp Plan") and authorized an
increase in the number of shares available for issuance from 457,037 to
967,890 shares. Under the terms of the merger, all stock option plans of
Cupertino National Bancorp and Mid-Peninsula Bancorp were terminated at the
time of the merger and all outstanding options from these plans were assumed
by the Bancorp Plan. Outstanding options from the Mid-Peninsula Bancorp plan
of 216,326 and outstanding options from the Cupertino National Bancorp plan of
251,073 (converted at a ratio of 0.81522) were assumed by the Bancorp Plan.
 
  Options issued under the Bancorp Plan may be granted to employees and
nonemployee directors and may be either incentive stock options or
nonqualified stock options as defined under current tax laws. The exercise
price of each option must equal the market price of the Company's stock on the
date of grant. The term of an option may not exceed 10 years.
 
  STOCK-BASED COMPENSATION
 
  In October 1995, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 123 "Accounting for Stock-Based Compensation". Under the provisions
of SFAS No. 123, the Company is encouraged, but not required, to measure
compensation costs related to its employee stock compensation plans under the
fair market value method. If the Company elects not to recognize compensation
expense under this method, it is required to disclose the pro forma net income
and earnings per share effects based on the SFAS No. 123 fair value
methodology. The Company implemented the requirements of SFAS No. 123 in 1996
and has elected to adopt the disclosure provisions of this statement.

  At December 31, 1996, the Company had one stock option plan, which is
described above. The Company applies Accounting Pronouncements Bulletin (APB)
Opinion No. 25 and related interpretations in accounting for its Plan.
Accordingly, no compensation cost has been recognized for its stock option
plan. Had compensation for the Company's stock option plan been determined
consistent with SFAS No. 123, the Company's net income and earnings per share
would have been reduced to the pro forma amounts indicated below:

  The fair value of each option grant is estimated on the date of the grant
using the Black-Scholes option-pricing model with the following weighted
average assumptions for grants in 1996 and 1995, respectively; dividend yield
of 2.0% for all years; expected volatility of 19.3% for both years; risk free
rates of 6.0% and 6.9%. No adjustments have been made for forfeitures. The
actual value, if any, that the option holder will realize from these options
will depend solely on the increase in the stock price over the option price
when the options are exercised.

  401(K) SAVINGS PLAN
 
  The Company has a 401(k) tax deferred savings plan under which eligible
employees may elect to defer a portion of their salary (up to 15%) as a
contribution to the plan. The Company matches the employee contributions at a
rate set by the Board of Directors (currently 62.5% of the first 8% of
deferral of an individual's total compensation). The matching contribution
vests ratably over the first four years of employment. The Company contributed
$282,000 to the plan in 1996, $212,000 in 1995, and $153,200 in 1994.

  EMPLOYEE STOCK PURCHASE PLAN
 
  The Company has established an Employee Stock Purchase Plan, as amended,
under section 423(b) of the Internal Revenue Code which allows eligible
employees to set aside up to 15% of their compensation toward the purchase of
the Company's stock for an aggregate total of 133,934 shares. Under the plan,
the purchase price is 85% of the lower of the fair market value at the
beginning or end of each three month offering period. During 1996, employees
purchased 10,633 shares of common stock for an aggregate purchase price of
$136,500 compared to the purchase of 8,536 shares of common stock for an
aggregate purchase price of $80,400 in 1995. There are 82,318 shares remaining
in the plan available for purchase by employees at December 31, 1996.
 
  SALARY COMPENSATION PLAN
 
  During 1993 and 1995, the Company entered into salary continuation
agreements with certain executive officers. Under these agreements, the
Company is generally obligated to provide for each such employee or their
beneficiaries, during a period of up to 40 years after the employee's death,
disability or retirement, annual benefits ranging from $36,000 to $85,000. The
estimated present value of future benefits to be paid is being accrued over
the vesting period of the participants. Expenses accrued for this plan for the
years ended December 31, 1996, 1995 and 1994 totaled $310,000, $173,000, and
$72,000, respectively. Depending on the agreement, the Company and the
employees are the beneficiaries of life insurance policies that have been
purchased as a method of financing the benefits under the agreements. At
December 31, 1996 and 1995, the Company's cash surrender value of these
policies was $8.9 million and $8.3 million, respectively, and is included in
other assets.

  The Company subleases that portion of the available space that is not
utilized. Sublease rental income for the years ended December 31, 1996, 1995,
and 1994 was $309,000, $398,000, and $447,000 respectively. Gross rental
expense for the years ended December 31, 1996, 1995, and 1994 was $1.69
million, $1.43 million, and $1.26 million respectively.
 
  OTHER COMMITMENTS AND CONTINGENT LIABILITIES
 
  In the normal course of business, various commitments and contingent
liabilities are outstanding, such as guarantees and commitments to extend
credit, that are not reflected in the accompanying consolidated financial
statements. At December 31, 1996, commitments to fund loans and outstanding
standby letters of credit were approximately $202.8 million and $16.9 million,
respectively. The Company's exposure to credit loss is limited to amounts
funded or drawn; however, at December 31, 1996, no losses are anticipated as a
result of these commitments.
 
  Loan commitments which have fixed expiration dates and require the payment
of a fee are typically contingent upon the borrower meeting certain financial
and other covenants. Approximately $60.0 million of these commitments relate
to real estate construction and land loans and are expected to fund within the
next 12 months. However, the remainder relate primarily to revolving lines of
credit or other commercial loans, and many of these commitments are expected
to expire without being drawn upon, therefore the total commitments do not
necessarily represent future cash requirements. Cupertino National Bank and
Mid-Peninsula Bank evaluate each potential borrower and the necessary
collateral on an individual basis. Collateral varies, but may include real
property, bank deposits, debt or equity securities, or business assets.
 
  Stand-by letters of credit are conditional commitments written by the Banks
to guarantee the performance of a client to a third party. These guarantees
are issued primarily relating to purchases of inventory by the Banks'
commercial clients, and are typically short-term in nature. Credit risk is
similar to that involved in extending loan commitments to clients, and the
Banks accordingly use evaluation and collateral requirements similar to those
for loan commitments. Virtually all such commitments are collateralized.
 
  In the ordinary course of business there are various assertions, claims and
legal proceedings pending against the Company. Management is of the opinion
that the ultimate resolution of these proceedings will not have a material
adverse effect on the consolidated financial position or results of operations
of the Company.
 
  In July 1995, the Company settled a lawsuit for $1.1 million (net of tax)
which alleged that the Company did not perform its fiduciary duties and, as a
result, the plaintiff incurred losses on real estate investments that were
purchased. The Company believes that insurance coverage for this settlement is
available to the Company under various insurance policies and the Company is
currently in the process of pursuing recovery under these policies. However,
due to the uncertainty associated with the recovery, the Company reflected the
settlement expense in 1995 earnings.
 
NOTE 14--REGULATORY MATTERS
 
  The Company and the Banks are subject to various regulatory capital
requirements administered by the federal banking agencies. Failure to meet
minimum capital requirements can initiate certain mandatory and possibly
additional discretionary actions by regulators that, if undertaken, could have
a direct material effect on the Company's consolidated financial statements.
Under capital adequacy guidelines and regulatory framework for prompt
corrective action, the Banks must meet specific capital guidelines that
involve quantitative measures of the Banks' assets, liabilities and certain
off-balance sheet items as calculated under regulatory accounting practices.
The Banks' capital amounts and classification are also subject to qualitative
judgments by the regulators about components, risk weightings and other
factors.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum capital amounts and ratios (as defined in
the regulations) and are set forth in the table below. At December 31, 1996,
the Bank meets all capital adequacy requirements to which it is subject.
 
  As of December 31, 1996, the most recent notification from all of the
Company's and the Banks' regulators, categorized the Company and the Banks as
well capitalized under the regulatory framework for prompt corrective action.
To be categorized as well capitalized, the Company and the Banks must maintain
minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set
forth in the following table. There are no conditions or events since that
determination that management believes have changed the institution's
category. The Company and the Banks' actual 1996 and 1995 capital amounts and
ratios are as follows:

NOTE 15--RESTRICTIONS ON SUBSIDIARY TRANSACTIONS
 
  One of the principal sources of cash for the Company is dividends from its
subsidiary Banks. Total dividends which may be declared by the Banks without
receiving prior approval from regulatory authorities are limited to the lesser
of the Banks' retained earnings or the net income of the Banks for the latest
three fiscal years, less dividends previously declared during that period.
Under these restrictions and considering minimum regulatory capital
requirements, the Banks are able to declare combined dividends of up to
approximately $6.3 million as of December 31, 1996.
 
  The Banks are subject to certain restrictions under the Federal Reserve Act,
including restrictions on the extension of credit to affiliates. In
particular, the Banks are prohibited from lending to the Company unless the
loans are secured by specified types of collateral. Such secured loans and
other advances from the Banks are limited to 10% of the Banks' shareholders'
equity, or a maximum of $4.4 million at December 31, 1996. No such advances
were made during 1996 or exist as of December 31, 1996.

</TABLE>
 
  The following methods and assumptions were used to estimate the fair value
of each class of financial instruments for which it is practicable to estimate
that value.
 
CASH AND CASH EQUIVALENTS
 
  The carrying value reported in the balance sheet for cash and cash
equivalents approximates fair value.
 
INVESTMENT SECURITIES
 
  The carrying amounts for short-term investments approximate fair value
because they mature in 90 days or less and do not present unanticipated credit
concerns. The fair value of longer term investments, except certain state and
municipal securities, is estimated based on bid prices published in financial
newspapers or bid quotations received from securities dealers. The fair value
of certain state and municipal securities is not readily available through
market sources other than dealer quotations, as such fair value estimates are
based on quoted market prices of similar instruments, adjusted for differences
between the quoted instruments and the instruments being valued.
 
LOANS
 
  Fair values are estimated for portfolios of loans with similar financial
characteristics. Loans are segregated by type such as commercial, commercial
real estate, residential mortgage and consumer. Each loan category is further
segmented into fixed and adjustable rate interest terms.
 
  The fair value of performing fixed rate loans is calculated by discounting
scheduled cash flows through the estimated maturity using estimated market
discount rates that reflect the credit and interest rate risk inherent in the
loan. The estimate of maturity is based on the Company's historical experience
with repayments for each

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
loan classifications, modified, as required, by an estimate of the effect of
current economic and lending conditions. The fair value of performing variable
rate loans is judged to approximate book value for those loans whose rates
reprice in less than 90 days. Rate floors and rate ceilings are not considered
for fair value purposes as the number of loans with such limitations is not
significant.
 
  Fair value for significant nonperforming loans is based on recent external
appraisals. If appraisals are not available, estimated cash flows are
discounted using a rate commensurate with the risk associated with the
estimated cash flows. Assumptions regarding credit risk, cash flows, and
discount rates are judgmentally determined using available market information
and specific borrower information.
 
DEPOSIT LIABILITIES AND BORROWINGS
 
  The fair value for all deposits without fixed maturities and short term
borrowings is considered to be equal to the carrying value. The fair value for
fixed rate time deposits and subordinated debt are estimated by discounting
future cash flows using interest rates currently offered on time deposits or
subordinated debt with similar remaining maturities.
 
COMMITMENTS TO EXTEND CREDIT AND STANDBY LETTER OF CREDIT
 
  The majority of the Company's commitments to extend credit carry current
market interest rates if converted to loans. Because these commitments are
generally unassignable by either the Company or the borrower, they only have
value to the Company and the borrower. The estimated fair value approximates
the recorded deferred fee amounts and is excluded from the table.
 
LIMITATIONS
 
  Fair value estimates are made at a specific point in time, based on relevant
market information and information about the financial instrument. These
estimates do not reflect any premium or discount that could result from
offering for sale, at one time, the Company's entire holdings of a particular
financial instrument. Fair value estimates are based on judgments regarding
future expected loss experience, current economic conditions, risk
characteristics of various financial instruments, and other factors. These
estimates are subjective in nature and involve uncertainties and matters of
significant judgment and therefore cannot be determined with precision.
Changes in assumptions could significantly affect the estimates.
 
  Fair value estimates are based on existing on- and off-balance sheet
financial instruments without attempting to estimate the value of anticipated
future business and the value of assets and liabilities that are not
considered financial instruments. In addition, the tax ramifications related
to the realization of the unrealized gains and losses can have a significant
effect on fair value estimates and have not been considered in many of the
estimates.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Greater Bay's Articles of Incorporation provide that the liability of the
directors of Greater Bay for monetary damages shall be eliminated to the
fullest extent permissible under California law and that Greater Bay is
authorized to provide for the indemnification of agents (as defined in Section
317 of the California General Corporation Law) of the corporation in excess of
that expressly permitted by such Section 317 for breach of duty to the
corporation and its shareholders to the fullest extent permissible under
California law.
 
  Section 317 sets forth the provisions pertaining to the indemnification of
corporate "agents." For purposes of this law, an agent is any person who is or
was a director, officer, employee or other agent of a corporation, or is or
was serving at the request of the corporation in such capacity with respect to
any other corporation, partnership, joint venture, trust or other enterprise.
Indemnification for expenses, including amounts paid on settling or otherwise
disposing of a threatened or pending action or defending against the same can
be made in certain circumstances by action of Greater Bay through: (1) a
majority vote of a quorum of Greater Bay's Board of Directors consisting of
directors who are not party to the proceedings; (2) approval of the
shareholders, with the shares owned by the person to be indemnified not being
entitled to vote thereon; or (3) such court in which the proceeding is or was
pending upon application by designated parties. Under certain circumstances,
an agent can be indemnified, even when found liable. Indemnification is
mandatory where the agent's defense is successful on the merits. The law
allows Greater Bay to make advances of expenses for certain actions upon the
receipt of an undertaking that the agent will reimburse the corporation if the
agent is found liable.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling Greater Bay,
pursuant to the foregoing provisions or otherwise, Greater Bay understands
that in the opinion of the Commission such indemnification is against public
policy as expressed in the Securities Act and is therefore unenforceable. In
the event that a claim for indemnification against such liabilities (other
than the payment by Greater Bay of expenses incurred or paid by a director,
officer or controlling person of Greater Bay in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, Greater
Bay will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against a public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
 
  Provisions regarding indemnification of officers and directors of Greater
Bay are contained in Greater Bay's Bylaws (Exhibit 3.2 to this Registration
Statement).
 
                                     II-1

  Under the Trust Agreement, Greater Bay will agree to indemnify each of the
Trustees of GBB Capital I or any predecessor Trustee for GBB Capital I, and to
hold each Trustee harmless against any loss, damage, claims, liability or
expense incurred without negligence or bad faith on its part, arising out of
or in connection with the acceptance or administration of the Trust Agreement,
including the costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers
or duties under the Trust Agreement.
 
  Greater Bay and GBB Capital I have agreed to indemnify the Underwriter, and
the Underwriter has agreed to indemnify GBB Capital I and Greater Bay against
certain civil liabilities, including liabilities under the Securities Act of
1933, as amended. Reference is made to the Purchase Agreement filed as Exhibit
1.1 herewith.

ITEM 17. UNDERTAKINGS
 
  (h) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrants pursuant to the foregoing provisions, or otherwise, the
Registrants have been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrants of expenses incurred or paid by a director, officer or controlling
person of the Registrants in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrants will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
 
  (i) The Registrants hereby undertake that:
 
    (1) For purposes of determining any liability under the Securities Act of
  1933, the information omitted from the form of prospectus filed as part of
  a registration statement in reliance upon Rule 430A and contained in the
  form of prospectus filed by the Registrants pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of the
  registration statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities Act
  of 1933, each post-effective amendment that contains a form of prospectus
  shall be deemed to be a new registration statement relating to the
  securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

Ladies and Gentlemen:

          Greater Bay Bancorp., a California corporation (the "Company"), and
its fiduciary subsidiary, GBB Capital I, a statutory business trust organized

Trust's  ___% Cumulative Capital Securities, with a liquidation preference of

more fully described in the Prospectus (as hereinafter defined).  The Offerors
propose that the Trust issue the Capital Securities pursuant to an Amended and
Restated Trust Agreement among Wilmington Trust Company, as Property Trustee and
Indenture Trustee, the administrative trustees named therein (the
"Administrative Trustees") and the Company (the "Trust Agreement").  The Capital

"Guarantee Trustee"), and entitled to the benefits of certain backup
undertakings described in the Prospectus (as defined herein) with respect to the
Company's agreement pursuant to the Expense Agreement (as defined herein) to pay
all expenses relating to administration of the Trust.

          The proceeds of the sale of the Capital Securities will be used to
purchase junior subordinated deferrable interest debentures (the "Junior

"Indenture").

          The Offerors hereby confirm their agreement with respect to the sale
of the Capital Securities to the Underwriter.

     1.   Registration Statement and Prospectus.  A registration
          -------------------------------------                 
statement on Form S-1 (File No. 333-____) with respect to the Capital
Securities, the Guarantee and the Junior Subordinated Debentures, including a
preliminary form of prospectus, has been prepared by the Offerors in conformity
with the requirements of the Securities Act of 1933, as amended (the "Act"), and
the rules and regulations ("Rules and Regulations") of the Securities and
Exchange Commission (the "Commission") thereunder and the Trust Indenture Act of
1939, as amended (the "Trust Indenture Act") and the rules and regulations
thereunder and has been filed with the Commission; and, if the Offerors have
elected to rely upon Rule 462(b) of the Rules and Regulations to increase the
size of the offering registered under the Act, the Offerors will prepare and
file with the Commission a registration statement with respect to such increase
pursuant to Rule 462(b).  Copies of such registration statement(s) and
amendments and each related preliminary prospectus have been delivered to the
Underwriter.

          If the Offerors have elected not to rely upon Rule 430A of the Rules
and Regulations, the Offerors have prepared and will promptly file an amendment
to the registration statement and an amended prospectus (including a term sheet
meeting the requirements of Rule 434 of the Rules and Regulations) if necessary
to complete the Prospectus.  If the Offerors have elected to rely upon Rule 430A
of the Rules and Regulations, they will prepare and file a prospectus (or a term
sheet meeting the requirements of Rule 434) pursuant to Rule 424(b) that
discloses the information previously omitted from the prospectus in reliance
upon Rule 430A. Such registration statement, as amended at the time it is or was
declared effective by the Commission, and, in the event of any amendment thereto
after the effective date and prior to the Closing Date (as hereinafter defined),
such registration statement as so amended (but only from and after the
effectiveness of such amendment), including a registration statement (if any)
filed pursuant to Rule 462(b) of the Rules and Regulations increasing the size
of the offering registered under the Act and information (if any) deemed to be
part of the registration statement at the time of effectiveness pursuant to
Rules 430A(b) and 434(d) of the Rules and Regulations, is hereinafter called the
"Registration Statement".  The prospectus included in the Registration Statement
at the time it is or was declared effective by the Commission is hereinafter
called the "Prospectus", except that if any prospectus (including any term sheet
meeting the requirements of Rule 434 of the Rules and Regulations provided by
the Offerors for use with a prospectus subject to completion within the meaning
of Rule 434 in order to meet the requirements of Section 10(a) of the Rules and
Regulations) filed by the Offerors with the Commission pursuant to Rule 424(b)
(and Rule 434, if applicable) of the Rules and Regulations or any

                                      -2-
<PAGE>
 
other such prospectus provided to the Underwriter by the Offeror for use in
connection with the offering of the Capital Securities (whether or not required
to be filed by the Offeror with the Commission pursuant to Rule 424(b) of the
Rules and Regulations) differs from the prospectus on file at the time the
Registration Statement is or was declared effective by the Commission, the term
"Prospectus" shall refer to such differing prospectus (including any term sheet
within the meaning of Rule 434 of the Rules and Regulations) from and after the
time such prospectus is filed with the Commission or transmitted to the
Commission for filing pursuant to such Rule 424(b) (and Rule 434, if applicable)
or from and after the time it is first provided to the Underwriter by the
Offeror for such use. The term "Preliminary Prospectus" as used herein means the
preliminary prospectus included in any Registration Statement prior to the time
it becomes or became effective under the Act and any prospectus subject to
completion as described in Rule 430A or 434 of the Rules and Regulations.

          In connection with the offer and sale of the Capital Securities, the
Underwriter will comply with Rule 2810 under the NASD Conduct Rules.

Underwriter as follows:

          (i) No order preventing or suspending the use of any Preliminary
Prospectus has been issued by the Commission, and the Preliminary Prospectus, at
the time of filing thereof, did not contain an 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 the light of the circumstances under which
they were made, not misleading; except that the foregoing shall not apply to

registered under the Act) is or was declared effective by the Commission, upon
the filing or first delivery to the Underwriter of the Prospectus (or any
supplement to the Prospectus (including any term sheet meeting the requirements
of Rule 434 of the Rules and Regulations)) and at the Closing Date (as
hereinafter defined), (A) the Registration Statement and Prospectus (in each
case, as so amended and/or supplemented) conformed or will conform in all
material respects to the requirements of the Act and the Rules and Regulations
and the Registration Statement and Prospectus (in each case as so amended

                                      -3-
<PAGE>
 
and/or supplemented) conformed or will conform in all material respects to the
requirements of the Trust Indenture Act and the rules and regulations
thereunder, (B) the Registration Statement (as so amended) did not or will not
include an 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 not
misleading, and (C) the Prospectus (as so supplemented) did not or will not
include an 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 in which they are or were made, not misleading;
except that the foregoing shall not apply to (i) statements in or omissions from
any such document in reliance upon, and in conformity with, written information
furnished to the Offerors by or on behalf of the Underwriter specifically for
use in the preparation thereof and (ii) that part of the Registration Statement
which constitutes the Statement of Eligibility and Qualification ("Form T-1")
under the Trust Indenture Act. If the Registration Statement has been declared
effective by the Commission, no stop order suspending the effectiveness of the
Registration Statement has been issued, and no proceeding for that purpose has
been initiated or, to the Offeror's knowledge, threatened by the Commission.

     (iii) The documents of the Company incorporated by reference in the
Registration Statement and the Prospectus, when they were filed with the
Commission conformed in all material respects to the requirements of the
Exchange Act and the rules and regulations of the Commission thereunder, and
none of such documents contained an untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein not misleading; and any further documents so filed
and incorporated by reference in the Registration Statement and the Prospectus
or any further amendment or supplement thereto, when such documents are filed
with the Commission will conform in all material respects to the requirements of
the Exchange Act and the rules and regulations of the Commission thereunder, and
will not contain an untrue statement of a material fact or omit to state a

subsidiaries as of the dates indicated and the results of operations and changes
in cash flows for the periods therein specified in conformity with generally

<PAGE>
 
Prospectus) and the independent public accountants whose reports are contained
therein are independent public accountants as required by the Act and the Rules
and Regulations. The summary financial information included in the Preliminary
Prospectus and Prospectus under the caption "Summary Consolidated Financial
Data" present fairly the information required to be stated therein.

     (v)  The Company has been duly organized and is validly existing as a
corporation in good standing under the laws of the State of California and is
duly registered as a bank holding company under the Bank Holding Company Act of
1956, as amended (the "BHC Act"), supervised by the Board of Governors of the
Federal Reserve System (the "FRB").  Other than the Trust, Mid-Peninsula Bank, a
state bank chartered under the banking laws of the State of California, and
Cupertino National Bank and Trust, a national banking association chartered
under the federal laws of the United States (each a "Subsidiary" and
collectively the "Subsidiaries"), constitute the only subsidiaries of the
Company.  Each Subsidiary has been duly organized and is validly existing and in
good standing under the laws of its jurisdiction of incorporation or
organization, as the case may be.  Each of the Company and its Subsidiaries has
full corporate power and authority to own its properties and conduct its
business as currently being carried on and as described in the Registration
Statement and Prospectus, and is duly qualified to do business as a foreign
corporation in good standing under the corporation and financial services laws
of each jurisdiction in which the conduct of its business or ownership or lease
of its properties requires such qualification and where the failure to be so
qualified would, individually or in the aggregate, have a material adverse
effect on the condition (financial or otherwise), earnings, business, prospects,
assets, results of operations or properties of the Company and its Subsidiaries,
taken as a whole.  Other than the foregoing Subsidiaries and the Trust, the
Company owns no capital stock or other equity, ownership or proprietary interest
in any company, partnership, association, trust or other entity.  The accounts
of each Subsidiary are insured by the Bank Insurance Fund of the Federal Deposit
Insurance Corporation (the "FDIC") up to the maximum applicable amount in
accordance with the rules and regulations of the FDIC, and no proceedings for
the termination or revocation of such membership or insurance are pending, or,
to the knowledge of the Company, threatened.

     (vi) The Trust has been duly created and is validly existing in good
standing as a business trust under the Delaware Act with full trust power and
authority to own property and to conduct its business as described in the
Registration Statement and Prospectus and to enter into and perform its
obligations under this Agreement, the Capital Securities, the Common Securities
and the Trust Agreement and is authorized to do business in each jurisdiction in
which such qualification is required, except where the failure to so qualify
would

                                      -5-

not have a material adverse effect on the Company's condition (financial or
otherwise), earnings, business, prospects, assets, results of operations or
properties taken as a whole; the Trust has conducted and will conduct no
business other than the transactions contemplated by the Trust Agreement and
described in the Prospectus; the Trust is not a party to or otherwise bound by
any agreement other than those described in the Prospectus; the Trust is and
will be classified for United States federal income tax purposes as a grantor
trust and not as an association taxable as a corporation; and the Trust is and
will be treated as a consolidated subsidiary of the Company pursuant to
generally accepted accounting principles.

     (vii)  Except as contemplated in the Prospectus, subsequent to the
respective dates as of which information is given in the Registration Statement
and the Prospectus, none of the Trust, the Company or the Subsidiaries has
incurred any material liabilities or obligations, direct or contingent, or
entered into any material transactions, or declared or paid any dividends or
made any distribution of any kind with respect to its capital stock (other than
dividends paid in the ordinary course with respect to shares of the Company's
Common Stock, no par value (the "Common Stock") or the common stock of the
Subsidiaries as described in the Registration Statement or the Prospectus); and
there has not been any change in the capital stock (other than a change in the
number of outstanding shares of Common Stock due to the issuance of shares upon
the exercise of options, warrants or rights under an employee stock purchase
plan disclosed in the Registration Statement or the Prospectus), or any material
change in the short-term or long-term debt, or any issuance of options,
warrants, convertible securities or other rights to purchase the capital stock,
of the Trust, the Company or any Subsidiary, or any material adverse change, or
any development involving a prospective material adverse change, in the general
affairs, condition (financial or otherwise), business, key personnel, property,
prospects, net worth or results of operations of the Trust or the Company and
its Subsidiaries, taken as a whole.

     (viii) Except as set forth in the Registration Statement and the Prospectus
or in the documents incorporated therein by reference, there is not pending or,
to the knowledge of the Trust or the Company, threatened or contemplated, any
action, suit or proceeding to which the Trust, the Company or any Subsidiary is
a party or to which either of their assets may be subject, before or by any
court or governmental agency, authority or body, or any arbitrator, which might
result in any material adverse change in the condition (financial or otherwise),
business, prospects, net worth or results of operations of the Trust or the
Company and its Subsidiaries, taken as a whole.

     (ix) There are no contracts or documents of the Trust, the Company or any
Subsidiary that are required to be filed or incorporated by reference as
exhibits to the Registration Statement by the Act or by the Rules and
Regulations which contracts or documents have not been so filed or incorporated
by reference as required.

     (x) Each of this Agreement, the Indenture, the Trust Agreement, the
Guarantee and the Agreement as to Expenses and Liabilities (the "Expense
Agreement") has been duly authorized, executed and delivered by the Company
and/or the Trust, as the case may be, and constitutes a valid, legal and binding
obligation of the Company and/or the Trust, as the case may be, enforceable in
accordance with its terms, except as rights to indemnity hereunder may be
limited by federal or state securities laws and except as such enforceability
may be limited by bankruptcy, insolvency, reorganization or similar laws
affecting the rights of creditors generally and subject to general principles of
equity. The execution, delivery and performance of this Agreement, the
Indenture, the Trust Agreement, the Guarantee Agreement and the Expense
Agreement and the consummation of the transactions herein or therein
contemplated will not result in a breach or violation of any of the terms and
provisions of, or constitute a default under, any statute, any agreement or
instrument to which the Company or the Trust is a party or by which it is bound
or to which any of its property is subject, the Company's charter or bylaws, the
Trust's Trust Agreement or its certificate of trust filed with the State of
Delaware on ________, 1997 (the "Certificate of Trust") or any order, rule,
regulation or decree of any court or governmental agency or body having
jurisdiction over the Company or the Trust or any of the properties of either
the Company or the Trust; no consent, approval, authorization or order of, or
filing with, any court or governmental agency or body is required for the
execution, delivery and performance of this Agreement, the Indenture, the Trust
Agreement, the Guarantee and the Expense Agreement or for the consummation of
the transactions contemplated hereby or thereby, including the issuance or sale
of the Junior Subordinated Debentures by the Company and the Capital Securities
by the Trust, except such as may be required under the Act or state securities

Trust Indenture Act and will conform in all material respects to the statements
relating thereto in the Registration Statement and the Prospectus.

securities laws, were not issued in violation of or subject to any preemptive
rights or other rights to subscribe for or purchase securities, and the holders
thereof are not subject to personal liability by reason of being such holders;
and the capital stock of the Company conforms to the description thereof in the
Registration Statement and Prospectus.  Except as otherwise stated in the
Registration Statement and Prospectus, there are no preemptive rights or other
rights to subscribe for or to purchase, or any restriction upon the voting or
transfer of, any shares of Common Stock pursuant to the Company's charter,
bylaws or any agreement or other instrument to which the Company is a party or
by which the Company is bound.  Neither the filing of the Registration Statement
nor the offering or sale of the Junior Subordinated Debentures or Capital
Securities as contemplated by this Agreement gives rise to any rights for or
relating to the registration of any shares of Common Stock or other capital
stock of the Company.  All of the issued and outstanding shares of capital stock
of each Subsidiary have been duly and validly authorized and issued and are
fully paid and nonassessable, and, except for any directors' qualifying shares,

capitalization as set forth in the Registration Statement and the Prospectus
under the caption "Capitalization".

Company and at the Closing Date will have been duly executed by the Company and,
when authenticated in the manner provided for in the Indenture and delivered
against payment therefor as described in the Prospectus, will constitute valid

accordance with their terms except to the extent that enforcement thereof may be
limited by bankruptcy, insolvency, reorganization or similar laws affecting the

     (xxviii) The proceeds from the sale of the Capital Securities will
constitute "tier 1" capital (as defined in 12 C.F.R. Part 325).

                                      -11-

     (xxix)  Neither of the Offerors nor any of their affiliates is presently
doing business with the government of Cuba or with any person or affiliate
located in Cuba.

     (xxx)   Each of the Subsidiaries has properly administered, in all respects
material and which could reasonably be expected to be material to the business,
operations or financial condition of the Company and its Subsidiaries, taken as
a whole, all accounts for which it acts as a fiduciary, including but not
limited to accounts for which it serves as a trustee, agent, custodian, personal
representative, guardian, conservator or investment advisor, in accordance with
the terms of the governing documents and applicable state and federal law and
regulation and common law. Neither of the Subsidiaries nor any director, officer
or employee of either Subsidiary has committed any breach of trust with respect
to any such fiduciary account which is material to or could reasonably be
expected to be material to the general affairs, condition (financial or
otherwise), business, key personnel, property, prospects, net worth or results
of operations of the Company and its Subsidiaries, taken as a whole, and the
accountings for each such fiduciary account are true and correct in all material
respects and accurately reflect the assets of such fiduciary account in all
material respects.

     (xxxi)  The conditions for use of Form S-1, as set forth in the
General Instructions thereto, have been satisfied.

     (xxxii) Each of the Company and its Subsidiaries is in compliance in all
material respects with all presently applicable provisions of the Employee
Retirement Income Security Act of 1974, as amended, including the regulations
and published interpretations thereunder ("ERISA"); no "reportable event" (as
defined in ERISA) has occurred with respect to any "pension plan" (as defined in
ERISA) which could have a material adverse effect on the general affairs,
management, financial position, stockholders' equity or results of operations of
the Company and its Subsidiaries for which the Company or any Subsidiary would
have any liability; neither the Company nor any Subsidiary has incurred or
expects to incur liability under (i) Title IV of ERISA with respect to
termination of, or withdrawal from, any "pension plan" or (ii) Sections 412 or
4971 of the Internal Revenue Code of 1986, as amended, including the regulations
and published interpretations thereunder (the "Code"), in each case which could
have a material adverse effect on the general affairs, management, financial
position, stockholders' equity or results of operations of the Company and its
Subsidiaries, taken as a whole; and each "pension plan" for which the Company or
any Subsidiary would have any liability that is intended to be qualified under
Section 501(a) of the Code is so qualified in all material respects and nothing
has occurred, whether by action or by failure to act, which would

                                      -12-
<PAGE>
 
     cause the loss of such qualification, except for such loss as would not
     have a material adverse effect on the general affairs, management,
     financial position, stockholders' equity or results of operations of the
     Company and its Subsidiaries, taken as a whole.

          (xxxiii) No hazardous substances, hazardous wastes, pollutants or
     contaminants have been deposited or disposed of in, on or under the
     properties of the Company or any Subsidiary (including properties owned,
     managed or controlled by a Subsidiary in connection with its lending
     operations) during the period in which the Company or any Subsidiary has
     owned, occupied, managed, controlled or operated such properties in
     violation of any applicable law, ordinance, rule, regulation, order,
     judgment, decree or permit or which would require remedial action under any
     applicable law, ordinance, rule, regulation, order, judgment, decree or
     permit, except for any violation or remedial action which would not have,
     or could not be reasonably likely to have, singularly or in the aggregate
     with all such violations or remedial actions, a material adverse effect on
     the general affairs, condition (financial or otherwise), business, key
     personnel, property, prospects, net worth or results of operations of the
     Company and its Subsidiaries, taken as a whole.

          (b)  Any certificate signed by any officer of the Company or a trustee
of the Trust and delivered to the Underwriter or to counsel for the Underwriter
shall be deemed a representation and warranty by the Company to the Underwriter
as to the matters covered thereby.

agrees to issue and sell ________ Capital Securities to the Underwriter, and the
Underwriter agrees to purchase the Capital Securities from the Trust at a

Underwriter for its commitments hereunder and in view of the fact that the
proceeds of the sale of the Capital Securities (together with the entire

agrees to pay at the Closing Date to the Underwriter, a commission per Capital

day next preceding the Closing Date at the offices of Piper Jaffray Inc., Piper
Jaffray Tower, 222 South Ninth Street, Minneapolis, Minnesota, or such other

          Nothing herein contained shall constitute the Underwriter an
unincorporated association or partner with either or both Offerors.

     4.   Covenants.
          --------- 

          (a) The Offerors jointly and severally covenant and agree with the
Underwriter as follows:

          (i) If the Registration Statement has not already been declared
effective by the Commission, the Company will use its best efforts to cause the
Registration Statement and any post-effective amendments thereto to become
effective as promptly as possible; the Company will notify the Underwriter
promptly of the time when the Registration Statement or any post-effective
amendment to the Registration Statement has become effective or any supplement
to the Prospectus (including any term sheet within the meaning of Rule 434 of
the Rules and Regulations) has been filed and of any request by the Commission
for any amendment or supplement to the Registration Statement or Prospectus or
additional information; if the Company has elected to rely on Rule 430A of the
Rules and Regulations, the Company will prepare and file a Prospectus (or term
sheet within the meaning of Rule 434 of the Rules and Regulations) containing
the information omitted therefrom pursuant to Rule 430A of the Rules and
Regulations with the Commission within the time period required by, and
otherwise in accordance with the provisions of, Rules 424(b), 430A and 434, if
applicable, of the Rules and Regulations; if the Company has elected to rely
upon Rule 462(b) of the Rules and Regulations to increase the size of the
offering registered under the Act, the Company will prepare and file a
registration statement with respect to such increase with the Commission within

                                      -14-
<PAGE>
 
the time period required by, and otherwise in accordance with the provisions of,
Rule 462(b); the Offerors will prepare and file with the Commission, promptly
upon the Underwriter's request, any amendments or supplements to the
Registration Statement or Prospectus (including any term sheet within the
meaning of Rule 434 of the Rules and Regulations) that, in the Underwriter's
opinion, may be necessary or advisable in connection with the Underwriter's
distribution of the Capital Securities; and the Offerors will not file any
amendment or supplement to the Registration Statement or Prospectus (including
any term sheet within the meaning of Rule 434 of the Rules and Regulations) to
which the Underwriter shall reasonably object by notice to the Company after
having been furnished a copy a reasonable time prior to the filing.

     (ii)  The Offerors will advise the Underwriter, promptly after they shall
receive notice or obtain knowledge thereof, of the issuance by the Commission of
any stop order suspending the effectiveness of the Registration Statement, of
the suspension of the qualification of the Capital Securities for offering or
sale in any jurisdiction, or of the initiation or threatening of any proceeding
for any such purpose; and the Offerors will promptly use their best efforts to
prevent the issuance of any stop order or to obtain its withdrawal if such a
stop order should be issued.

     (iii) Within the time during which a prospectus (including any term sheet
within the meaning of Rule 434 of the Rules and Regulations) relating to the
Capital Securities is required to be delivered under the Act, the Offerors will
comply as far as it is able with all requirements imposed upon it by the Act, as
now and hereafter amended, and by the Rules and Regulations, as from time to
time in force, so far as necessary to permit the continuance of sales of or
dealings in the Capital Securities as contemplated by the provisions hereof and
the Prospectus. If during such period any event occurs as a result of which the
Prospectus would include an untrue statement of a material fact or omit to state
a material fact necessary to make the statements therein, in the light of the
circumstances then existing, not misleading, or if during such period it is
necessary to amend the Registration Statement or supplement the Prospectus to
comply with the Act, the Offerors will promptly notify the Underwriter and will
amend the Registration Statement or supplement the Prospectus (at the expense of
the Company) so as to correct such statement or omission or effect such
compliance.

     (iv)  The Offerors will use their best efforts to qualify the Capital
Securities, the Junior Subordinated Debentures and the Guarantee for sale under
the securities laws of such jurisdictions as the Underwriter may reasonably
designate and to continue such qualifications in effect so long as required for 
the

                                      -15-
<PAGE>
 
distribution of the Capital Securities, except that the Offerors shall not
be required in connection therewith to qualify as a foreign corporation or to
execute a general consent to service of process in any state.

     (v)    The Offerors will furnish to the Underwriter copies of the
Registration Statement (three of which will be signed and will include all
exhibits), each of the Preliminary Prospectuses, the Prospectus, and all
amendments and supplements (including any term sheet within the meaning of Rule
434 of the Rules and Regulations) to such documents, in each case as soon as
available and in such quantities as the Underwriter may from time to time
reasonably request.

     (vi)   During a period of five years commencing with the date hereof the
Company will furnish to the Underwriter copies of all periodic and special
reports furnished to the stockholders of the Company and all information,
documents and reports filed with the Commission.

security holders and holders of the Capital Securities as soon as practicable,
but in any event not later than 15 months after the end of the Company's current
fiscal quarter, an earnings statement (which need not be audited) covering a 12-
month period beginning after the effective date of the Registration Statement
that shall satisfy the provisions of Section 11(a) of the Act and Rule 158 of
the Rules and Regulations.

     (viii) The Company, whether or not the transactions contemplated hereunder
are consummated or this Agreement is prevented from becoming effective under the
provisions of Section 8(a) hereof or is terminated, will pay or cause to be paid
(A) all expenses (including transfer taxes allocated to the respective
transferees) incident to the performance of the obligations of each Offeror
under this agreement, (B) all expenses and fees (including, without limitation,
fees and expenses of each Offeror's accountants and counsel but, except as
otherwise provided below, not including fees of the Underwriter's counsel) in
connection with the preparation printing, filing, delivery, and shipping of the

amendments, schedules, and exhibits thereto), the Capital Securities, each
Preliminary Prospectus, the Prospectus, and any amendment thereof or supplement
thereto, and the printing, delivery, and shipping of this Agreement and other
underwriting documents, including Blue Sky Memoranda, (C) all filing fees and
fees and disbursements of the Underwriter's counsel incurred in connection with
the qualification of the Capital Securities for offering and sale by the
Underwriter or by dealers under the securities or blue sky laws of the states
and other jurisdictions which the Underwriter shall designate, (D) the fees and

                                      -16-
<PAGE>
 
expenses of any transfer agent or registrar, (E) the filing fees incident to any
required review by the National Association of Capital Securities Dealers, Inc.
("NASD") of the terms of the sale of the Capital Securities, (E) listing fees,
if any, (G) the fees and expenses of the Indenture Trustee, including the fees

Indenture and Junior Subordinated Debentures, (H) the fees and expenses of the
Property Trustee, including the fees and disbursements of counsel for the
Property Trustee in connection with the Trust Agreement and the Certificate of
Trust, and (I) all other costs and expenses incident to the performance of the
Offerors' obligations hereunder that are not otherwise specifically provided for
herein. If the sale of the Capital Securities provided for herein is not
consummated by reason of action by either Offeror pursuant to Section 8(a)
hereof which prevents this Agreement from becoming effective, or by reason of
any failure, refusal or inability on the part of either Offeror to perform any
agreement on its part to be performed, or because any other condition of the
Underwriter's obligations hereunder required to be fulfilled by either Offeror
is not fulfilled, the Company will reimburse the Underwriter for all out-of-
pocket disbursements (including fees and disbursements of counsel) incurred by
the Underwriter in connection with its investigation, preparing to market and
marketing the Capital Securities or in contemplation of performing their
obligations hereunder. Neither Offeror shall in any event be liable to the
Underwriter for loss of anticipated profits from the transactions covered by
this Agreement.

     (ix) The Offerors will apply the net proceeds from the sale of the Capital
Securities to be sold by the Trust hereunder for the purposes set forth in the
Prospectus and will file such reports with the Commission with respect to the
sale of the Capital Securities and the application of the proceeds therefrom as
may be required in accordance with Rule 463 of the Rules and Regulations.

     (x)  The Offerors have not taken and will not take, directly or indirectly,
any action designed to or which might reasonably be expected to cause or result
in, or which has constituted, the stabilization or manipulation of the price of
any security of either Offeror to facilitate the sale or resale of the Capital
Securities, and has not effected any sales of Common Stock which are required to
be disclosed in response to Item 701 of Regulation S-K under the Act which have
not been so disclosed in the Registration Statement.

     (xi) Neither Offeror will incur any liability for any finder's or broker's
fee or agent's commission in connection with the execution and delivery of this
Agreement or the consummation of the transactions contemplated hereby.

                                      -17-

          (xii) The Offerors will inform the Florida Department of Banking and
Finance at any time prior to the consummation of the distribution of the Capital
Securities by the Underwriter if it commences engaging in business with the
government of Cuba or with any person or affiliate located in Cuba. Such
information will be provided within 90 days after the commencement thereof or
after a change occurs with respect to previously reported information.

     5.   Conditions of Underwriter's Obligations. The obligations of the
          ---------------------------------------
Underwriter hereunder are subject to the accuracy, as of the date hereof and at
the Closing Date (as if made at the Closing Date), of and compliance with all
representations, warranties and agreements of the Offerors contained herein, to
the performance by each Offeror of its obligations hereunder and to the
following additional conditions:

          (a) The Registration Statement shall have become effective not later
than 5:00 p.m., Central time, on the date of this Agreement, or such later time
and date as the Underwriter shall approve and all filings required by Rules 424,
430A and 434 of the Rules and Regulations shall have been timely made; no stop
order suspending the effectiveness of the Registration Statement or any
amendment thereof shall have been issued and no proceedings for the issuance of
such an order shall have been initiated or threatened; and any request of the
Commission for additional information (to be included in the Registration
Statement or the Prospectus or otherwise) shall have been complied with to the
Underwriter's satisfaction.

          (b) The Underwriter shall not have advised the Company or the Trust
that the Registration Statement or the Prospectus, or any amendment thereof or
supplement thereto (including any term sheet within the meaning of Rule 434 of
the Rules and Regulations), contains an untrue statement of fact which, in the
Underwriter's opinion, is material, or omits to state a fact which, in the
Underwriter's opinion, is material and is required to be stated therein or
necessary to make the statements therein not misleading.

          (c) Except as contemplated in the Prospectus, subsequent to the
respective dates as of which information is given in the Registration Statement
and the Prospectus, none of the Trust, the Company nor any Subsidiary shall have
incurred any material liabilities or obligations, direct or contingent, or
entered into any material transactions, or declared or paid any dividends or
made any distribution of any kind with respect to its capital stock; and there
shall not have been any change in the capital stock (other than a change in the
number of outstanding shares of Common Stock due to the issuance of shares upon
the exercise of options, warrants or rights under any employee stock purchase
plan disclosed in the Registration Statement or the Prospectus), or any material
change in the short-term or long-term debt of the Company, or any issuance of
options, warrants, convertible securities or other rights to

                                      -18-
<PAGE>
 
purchase the capital stock of the Company or any of its subsidiaries, or any
material adverse change or any development involving a prospective material
adverse change (whether or not arising in the ordinary course of business), in
the general affairs, condition (financial or otherwise), business, key
personnel, property, prospects, net worth or results of operations of the Trust
or the Company and its Subsidiaries, taken as a whole, that, in the
Underwriter's judgment, makes it impractical or inadvisable to offer or deliver
the Capital Securities on the terms and in the manner contemplated in the
Prospectus.

          (d)  On the Closing Date, there shall have been furnished to the
Underwriter the opinion of Manatt, Phelps & Phillips, LLP, counsel for the
Company, dated the Closing Date and addressed to the Underwriter, to the effect
that:

          (i)  Each of the Company and its Subsidiaries has been duly organized
and is validly existing as a corporation in good standing under the laws of its
jurisdiction of incorporation or organization. The Company has been duly
organized and is validly existing as a corporation in good standing under the
laws of the State of California and is duly registered as a bank holding company
under the BHC Act. Mid-Peninsula Bank has been duly organized and is validly
existing as a state bank in good standing under the banking laws of the State of
California. Cupertino National Bank and Trust has been duly organized and is
validly existing as a national banking association in good standing under the
federal laws of the United States. Each of the Company and its Subsidiaries has
the corporate power and authority to own its properties and conduct its business
as currently being carried on and as described in the Registration Statement and
Prospectus, and is duly qualified to do business as a foreign corporation and is
in good standing in each jurisdiction in which its ownership or lease of real
property or the conduct of its business makes such qualification necessary and
in which the failure to so qualify would have a material adverse effect upon the
business, condition (financial or otherwise) or properties of the Company and
its Subsidiaries, taken as a whole.

          (ii) The statements in the Prospectus under the caption "Description
of the Trust Preferred", "Description of Junior Subordinated Debentures",
"Description of Guarantee", and "Relationship among the Trust Preferred
Securities, the Junior Subordinated Debentures and the Guarantee", insofar as
such statements constitute matters of law applicable to the Offerors or
summaries of documents, fairly present the information required to be included
therein in all material respects. All of the issued and outstanding shares of
the capital stock of the Company have been duly authorized and validly issued
and are fully paid and nonassessable, and the holders thereof are not subject to
personal liability by reason of being such holders. Except as otherwise stated
in the Registration Statement and Prospectus, there are no preemptive or other
similar rights or

                                      -19-
<PAGE>
 
options, warrants, agreements, contracts or other rights in existence to
purchase or acquire from the Company any shares of the capital stock of the
Company pursuant to the Company's charter, bylaws or any agreement or other
instrument known to such counsel to which the Company is a party or by which the
Company is bound. To the best of such counsel's knowledge, neither the filing of
the Registration Statement nor the offering or sale of the Junior Subordinated
Debentures or Capital Securities as contemplated by this Agreement gives rise to
any rights for or relating to the registration of any shares of Common Stock or
other securities of the Company.

     (iii) All of the issued and outstanding shares of capital stock of each
Subsidiary have been duly and validly authorized and issued and are fully paid
and nonassessable, and, to the best of such counsel's knowledge, except as
otherwise described in the Registration Statement and Prospectus and except for
directors' qualifying shares, the Company owns of record and beneficially, free
and clear of any security interests, claims, liens, proxies, equities or other
encumbrances all of the issued and outstanding shares of capital stock of each
Subsidiary. To the best of such counsel's knowledge, except as described in the
Registration Statement and Prospectus, there are no options, warrants,
agreements, contracts or other rights in existence to purchase or acquire from
the Company or any Subsidiary any shares of the capital stock of any Subsidiary.

     (iv)  All of the issued and outstanding Common Securities of the Trust are
owned by the Company, free and clear of any security interest, mortgage, pledge,
lien, encumbrance, claim or equitable right.

     (v)   The Trust Agreement has been duly qualified under the Trust Indenture
Act.

     (vi)  The Junior Subordinated Debentures are in the form contemplated by
the Indenture, have been duly authorized, executed and delivered by the Company
and, when authenticated by the Indenture Trustee in the manner provided for in
the Indenture and delivered against payment therefor, will constitute valid and
binding obligations of the Company, enforceable against the Company in
accordance with their terms, except to the extent that enforcement thereof may
be limited by bankruptcy, insolvency, reorganization or similar laws affecting
the rights of creditors generally and subject to general principles of equity.

     (vii) The Junior Subordinated Debentures are subordinate and junior in
right of payment to all Senior and Subordinated Debts (as defined in the
Indenture) of the Company.

                                      -20-
<PAGE>
 
     (viii) Neither the Company nor the Trust is an "investment company" or a
company "controlled" by an "investment company" within the meaning of the 1940
Act.

     (ix)   The statements set forth in the Prospectus under the caption
"Certain Federal Income Tax Consequences" constitute a fair and accurate summary
of the matters addressed therein, based upon current law and the assumptions
stated or referred to therein.

     (x)    Under current law, the Trust will be classified for United States
federal income tax purposes as a grantor trust and not as an association taxable
as a corporation; accordingly, for United States federal income tax purposes
each beneficial owner of Capital Securities will be treated as owning an
undivided beneficial interest in the Junior Subordinated Debentures, and stated
interest on the Junior Subordinated Debentures generally will be included in
income by a holder of Capital Securities at the time such interest income is
paid or accrued in accordance with such holder's regular method of tax
accounting.

     (xi)   For federal income tax purposes, (a) the Junior Subordinated
Debentures will constitute indebtedness of the Company and (b) the interest on
the Junior Subordinated Debentures will be deductible by the Company on an
economic accrual basis in accordance with Section 163(e) of the Internal Revenue
Code of 1986, as amended, and Treasury Regulation Section 1.163-7.

     (xii)  To the best of such counsel's knowledge and information after due
inquiry, the Trust is not required to be authorized to do business in any other
jurisdiction and the Trust is not a party to or otherwise bound by any agreement
other than those described in the Prospectus.

     (xiii) The Trust Agreement has been duly authorized, executed and delivered
by the Company and the Administrative Trustees.

     (xiv)  The Registration Statement has become effective under the Act and,
to the best of such counsel's knowledge, no stop order suspending the
effectiveness of the Registration Statement has been issued and no proceeding
for that purpose has been instituted or, to the knowledge of such counsel,
threatened by the Commission.

     (xv)   The descriptions in the Registration Statement and Prospectus of
statutes, legal and governmental proceedings or rulings, contracts and other
documents are accurate in all material respects and fairly present the
information required to be shown; and such counsel does not know of any statutes
or legal or governmental proceedings required to be described in the
Prospectuses that are

                                      -21-
<PAGE>
 
not described as required, or of any contracts or documents of a character
required to be described in the Registration Statement or Prospectus or included
as exhibits to the Registration Statement that are not described or included as
required.

     (xvi)  The reports of the Company incorporated by reference in the
Registration Statement and the Prospectus or any further amendment or supplement
thereto made by the Company (other than the financial statements, other
financial data and related schedules therein, as to which such counsel need
express no opinion), when they were filed with the Commission, complied as to
form in all material respects with the requirements of the Exchange Act and the
rules and regulations of the Commission thereunder.

     (xvii) The Company has full corporate power and authority and the Trust has
full trust power and authority to enter into this Agreement, the Indenture, the
Trust Agreement, the Guarantee Agreement and the Expense Agreement to which it
is a party and to issue the Junior Subordinated Debentures and Capital
Securities, as the case may be, and to effect the transactions contemplated by
this Agreement, the Indenture, the Trust Agreement, the Guarantee Agreement and
the Expense Agreement to which it is a party. This Agreement has been duly
authorized, executed and delivered by the Company, and each of the Indenture,
the Trust Agreement, the Guarantee Agreement and the Expense Agreement has been
duly authorized, executed and delivered by the Company and constitutes a valid,
legal and binding obligation of the Company enforceable in accordance with its
terms (except as rights to indemnity hereunder may be limited by federal or
state securities laws and except as such enforceability may be limited by
bankruptcy, insolvency, reorganization or similar laws affecting the rights of
creditors generally and subject to general principles of equity). The execution,
delivery and performance of this Agreement, the Indenture, the Trust Agreement,
the Guarantee Agreement, the Capital Securities, the Common Securities, the
Junior Subordinated Debentures and the Guarantee and the consummation of the
transactions herein or therein contemplated will not result in a breach or
violation of any of the terms and provisions of, or constitute a default under,
(A) any statute, rule or regulation of the United States or the State of
California, or any rule or regulation of any Banking Regulator, or (B) any
agreement or instrument know to such counsel to which the Company or the Trust
is a party or by which either is bound or to which any of their property is
subject which agreement or instrument is material to the Company and its
Subsidiaries, taken as a whole, or (C) the charter or bylaws of the Company or
any Subsidiary, or the Trust's Certificate, or (D) any order or decree known to
such counsel of any court, governmental agency or body or Banking Regulator
having jurisdiction over the Company, any Subsidiary or the Trust or any of its
respective properties, except for any breach, violation or default which would

                                      -22-
<PAGE>
 
     not have a material adverse effect on the Company and its Subsidiaries,
     taken as a whole, or the ability of the Company or the Trust to perform its
     obligations hereunder; and no consent, approval, authorization or order of,
     or filing with, any court or governmental agency or body is required for
     the execution, delivery and performance of this Agreement, the Indenture,
     the Trust Agreement, the Guarantee Agreement, the Expense Agreement, the
     Capital Securities, the Junior Subordinated Debentures, or the Guarantee or
     for the consummation of the transactions contemplated hereby or thereby,
     including the issuance or sale of the Junior Subordinated Debentures by the
     Company and the Common Securities and Capital Securities by the Trust,
     except (a) such as may be required under the Act, which has been obtained,
     or under state securities or blue sky laws, and (b) the qualification of
     the Trust Agreement, the Guarantee Agreement and the Indenture under the
     Trust Indenture Act and the rules and regulations thereunder.

          (xviii) The Registration Statement and the Prospectus, and any
     amendment thereof or supplement thereto (including any term sheet within
     the meaning of Rule 434 of the Rules and Regulations), comply as to form in
     all material respects with the requirements of the Act and the Rules and
     Regulations; and on the basis of conferences with officers of the Company,
     examination of documents referred to in the Registration Statement and
     Prospectus and such other procedures as such counsel deemed appropriate,
     nothing has come to the attention of such counsel that causes such counsel
     to believe that the Registration Statement or any amendment thereof, at the
     time such Registration Statement became effective and as of the Closing
     Date (including any Registration Statement filed under Rule 462(b) of the
     Rules and Regulations), contained any untrue statement of a material fact
     or omitted to state any material fact required to be stated therein or
     necessary to make the statements therein not misleading or that the
     Prospectus (as of their respective dates and as of the Closing Date), as
     amended or supplemented, includes any untrue statement of material fact or
     omits to state a material fact necessary to make the statements therein, in
     light of the circumstances under which they were made, not misleading; it
     being understood that such counsel need express no opinion as to the
     financial statements or other financial data included in any of the
     documents mentioned in this clause.

          In rendering such opinion such counsel may rely (i) as to matters of
law other than California and federal law, upon the opinion or opinions of local
counsel provided that the extent of such reliance is specified in such opinion
and that such counsel shall state that such opinion or opinions of local counsel
are satisfactory to them and that they believe they and the Underwriter are
justified in relying thereon and (ii) as to matters of fact, to the extent such
counsel deems reasonable upon certificates of

                                      -23-
<PAGE>
 
officers of the Company and its subsidiaries and of public officials provided
that the extent of such reliance is specified in such opinion.

     its obligations under this Agreement do not violate (a) any of the
     provisions of the Certificate of Trust or the Trust Agreement, or (b) any
     applicable Delaware law or Delaware administrative regulation.

the Closing Date shall be to confirm the conclusions and findings set forth in
such prior letter.

          (i) On the Closing Date, there shall have been furnished to the
Underwriter, a certificate, dated the Closing Date and addressed to the
Underwriter, signed by the chief executive officer and by the chief financial
officer of the Company, to the effect that:

     contemplated by the Commission or any state or regulatory body; and

          (iii) The signers of said certificate have carefully examined
     the Registration Statement and the Prospectus, and any amendments thereof
     or supplements thereto (including any term sheet within the meaning of Rule

     Prospectus), or any material change in the short-term or long-term debt, or
     any issuance of options, warrants, convertible securities or other rights
     to purchase the capital stock, of the Company, or any of its Subsidiaries,
     or any material adverse change or any development involving a prospective
     material adverse change (whether or not arising in the ordinary course of
     business), in the general affairs, condition (financial or otherwise),
     business, key personnel, property, prospects, net worth or results of
     operations of the Trust or the Company and its Subsidiaries, taken as a

<PAGE>
 
     prospects or results of operations of the Company and its subsidiaries,
     taken as a whole.

          (j)  On the Closing Date, there shall have been furnished to the
Underwriter, a certificate, dated the Closing Date and addressed to the
Underwriter, signed by the Administrative Trustees, to the effect that:

          (i)  The representations and warranties of the Trust in this Agreement
     are true and correct, in all material respects, as if made at and as of the
     Closing Date, and the Trust has complied with all the agreements and

     contemplated by the Commission or any state or regulatory body; and

Underwriter's counsel such additional documents, certificates and evidence as
the Underwriter or they may have reasonably requested.

     6.   Indemnification and Contribution.
          --------------------------------

     (a)  The Offerors agree to indemnify and hold harmless the Underwriter
against any losses, claims, damages or liabilities to which the Underwriter may
become subject, under the Act or otherwise (including in settlement of any
litigation if such settlement is effected with the written consent of the
Company), insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement,
including the information deemed to be a part of the Registration Statement at
the time of effectiveness pursuant to Rules 430A and 434(d) of the Rules and
Regulations, if applicable, any Preliminary Prospectus, the Prospectus, or any
amendment or supplement thereto (including any term sheet within the meaning of
Rule 434 of the Rules and Regulations), or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
will reimburse the Underwriter for any legal or other expenses reasonably
incurred by it in connection with investigating or defending against such loss,
claim, damage, liability or action; provided, however, that the Offerors shall
not be liable in any such case to the extent that any such loss, claim, damage,
liability or action arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in the
Registration Statement, any Preliminary Prospectus, the Prospectus, or any such
amendment or supplement, in reliance upon and in conformity with written
information furnished to the Offerors by or on behalf of the Underwriter
specifically for use in the preparation thereof.

          In addition to its other obligations under this Section 6(a), each of
the Company and the Trust agree that, as an intern measure during the pendency
of any

                                      -29-
<PAGE>
 
claim, action, investigation, inquiry or other proceeding arising out of or
based upon any statement or omission, or any alleged statement or omission,
described in this Section 6(a), it will reimburse the Underwriter on a monthly
basis for all reasonable legal tees or other expenses incurred in connection
with investigating or defending any such claim, action, investigation, inquiry
or other proceeding, notwithstanding the absence of a judicial determination as
to the propriety and enforceability of the Offerors' obligation to reimburse the
Underwriter for such expenses and the possibility that such payments might later
be held to have been improper by a court of competent jurisdiction. To the
extent that any such interim reimbursement payment is so held to have been
improper, the Underwriter shall promptly return it to the party or parties that
made such payment, together with interest, compounded daily, determined on the
basis of the prime rate (or other commercial lending rate for borrowers of the
highest credit standing) announced from time to time by Norwest Bank Minnesota,
N.A. (the "Prime Rate"). Any such interim reimbursement payments which are not
made to the Underwriter within 30 days of a request for reimbursement shall bear
interest at the Prime Rate from the date of such request. This indemnity
agreement shall be in addition to any liabilities which the Company may
otherwise have.

          (b) The Underwriter will indemnify and hold harmless the Company and
the Trust against any losses, claims, damages or liabilities to which the
Company and the Trust may become subject, under the Act or otherwise (including
in settlement of any litigation, if such settlement is effected with the
Underwriter's written consent), insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in the
Registration Statement, any Preliminary Prospectus, the Prospectus, or any
amendment or supplement thereto (including any term sheet within the meaning of
Rule 434 of the Rules and Regulations), or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, in
each case to the extent, but only to the extent, that such untrue statement or
alleged untrue statement or omission or alleged omission was made in the
Registration Statement, any Preliminary Prospectus, the Prospectus, or any such
amendment or supplement, in reliance upon and in conformity with written
information furnished to the Company by or on behalf of the Underwriter for use
in the preparation thereof, and will reimburse the Company and the Trust for any
legal or other expenses reasonably incurred by the Company and the Trust in
connection with investigating or defending against any such loss, claim, damage,
liability or action.

          (c) The Company agrees to indemnify the Trust against all loss,
liability, claim damage and expense whatsoever, which may become due from the
Trust under subsection (a).

                                      -30-
<PAGE>
 
          (d) Promptly after receipt by an indemnified party under subsection
(a) or (b) above of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve the indemnifying party from any liability
that it may have to any indemnified party.  In case any such action shall be
brought against any indemnified party, and it shall notify the indemnifying
party of the commencement thereof, the indemnifying party shall be entitled to
participate in, and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party, and after notice from the
indemnifying party to such indemnified party of the indemnifying party's
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal or other
expenses subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation; provided, however,
that if, in the sole judgment of the Underwriter, it is advisable for it to be
represented by separate counsel, the Underwriter shall have the right to employ
a single counsel to represent all persons who may be subject to a liability
arising from any claim in respect of which indemnity may be sought by the
Underwriter under this Section 6, in which event the reasonable fees and
expenses of such separate counsel shall be borne by the indemnifying party or
parties and remitted to the Underwriter for payment to such counsel as such fees
and expenses are incurred (in accordance with the provisions of the second
paragraph in subsection (a) above).  An indemnifying party shall not be
obligated under any settlement agreement relating to any action under this
Section 6 to which it has not agreed in writing.

          (e) If the indemnification provided for in this Section 6 is
unavailable or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities referred to in subsection (a) or (b) above, (i)
in such proportion as is appropriate to reflect the relative benefits received
by the Company or the Trust on the one hand and the Underwriter on the other
from the offering of the Capital Securities or (ii) if the allocation provided
by clause (i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Company and the Trust on the one hand
and the Underwriter on the other in connection with the statements or omissions
that resulted in such losses, claims, damages or liabilities, as well as any
other relevant equitable considerations. The relative benefits received by the
Company and the Trust on the one hand and the Underwriter on the other shall be
deemed to be in the same proportion as the total net proceeds from the offering
(before deducting expenses) received by the Company bear to the total
underwriting discounts and commissions received by the Underwriter, in each case
as set forth in the table on the cover page of the Prospectus. The relative
fault

                                      -31-
<PAGE>
 
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information supplied by the Company, the
Trust or the Underwriter and the parties' relevant intent, knowledge, access to
information and opportunity to correct or prevent such untrue statement or
omission. The Company and the Trust and the Underwriter agree that it would not
be just and equitable if contributions pursuant to this subsection (e) were to
be determined by pro rata allocation or by any other method of allocation which
does not take account of the equitable considerations referred to in the first
sentence of this subsection (e). The amount paid by an indemnified party as a
result of the losses, claims, damages or liabilities referred to in the first
sentence of this subsection (e) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending against any action or claim which is the subject of
this subsection (e). Notwithstanding the provisions of this subsection (e), the
Underwriter shall not be required to contribute any amount in excess of the
amount by which the total price at which the Capital Securities underwritten by
it and distributed to the public were offered to the public exceeds the amount
of any damages that such Underwriter has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11 (f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

          (f) The obligations of the Company under this Section 6 shall be in
addition to any liability which the Company and the Trust may otherwise have and
shall extend, upon the same terms and conditions, to each person, if any, who
controls the Underwriter within the meaning of the Act; and the obligations of
the Underwriter under this Section 6 shall be in addition to any liability that
the Underwriter may otherwise have and shall extend, upon the same terms and
conditions, to each director of the Company (including any person who, with his
or her consent, is named in the Registration Statement as about to become a
director of the Company), to each officer of the Company who has signed the
Registration Statement and to each person, if any, who controls the Company or
the Trust within the meaning of the Act.

     7.   Representations and Agreements to Survive Delivery. All
          --------------------------------------------------
representations, warranties, and agreements of the Offerors herein or in
certificates delivered pursuant hereto, and the agreements of the Offerors and
the Underwriter contained in Section 6 hereof shall remain operative and in full
force and effect regardless of any investigation made by the Underwriter or on
the Underwriter's behalf or any controlling person thereof, or the Company or
any of its officers, directors, or controlling persons or the Trust or any if
its trustees, or controlling persons and shall survive delivery of, and payment
for, the Capital Securities to and by the Underwriter hereunder.

public upon release by the Underwriter of the publication of a newspaper
advertisement relating thereto or upon release by the Underwriter of telexes

first occur.  By giving notice as hereinafter specified before the time this
Agreement becomes effective, the Underwriter, the Trust or the Company may

other event or occurrence of a similar character shall have occurred since the
execution of this Agreement that, in the Underwriter's judgment, makes it
impractical or inadvisable to proceed with the completion of the sale of and
payment for the Capital Securities. Any such termination shall be without
liability of any party to any other party except that the provisions of Section
4(a)(viii) and Section 6 hereof shall at all times be effective.

          ----------------
Article VII hereof), Cupertino shall be merged with and into Mid-Peninsula, 
Mid-Peninsula shall change its name to Greater Bay Bancorp, which shall

     1.2 Rights and Duties of Surviving Corporation. At and after the Effective

Time of the Merger, all rights, privileges, powers and franchises and all
property and assets of every kind and description of Cupertino shall be vested
in and be held and enjoyed by Bancorp as the Surviving Corporation, without
further act or deed; all the estates and interests of every kind of Cupertino,

preserved unimpaired and all debts, liabilities and duties of Mid-Peninsula or

                                  ARTICLE II
                             CONVERSION OF SHARES
                             --------------------

     2.1  Conversion of Shares.  In and by virtue of the Merger and at the 
          --------------------
Effective Time of the Merger, pursuant to this Merger Agreement, each 
Mid-Peninsula Share and each Cupertino Share issued and outstanding immediately 
prior to the Effective time of the Merger shall, at the Effective Time of the 
Merger, be converted.

          a. Effect on Mid-Peninsula Shares. At the Effective Time of the
             ------------------------------
Merger, each Mid-Peninsula Share issued and outstanding immediately prior to the
Effective Time of the Merger shall, on and after the Effective Time of the
Merger, remain issued and outstanding and shall automatically and for all
purposes be deemed to represent one share of the common stock, without par
value, of Bancorp as the Surviving Corporation ("Bancorp Shares").

          b.  Conversion of Cupertino Shares.  At the Effective Time of the 
              ------------------------------
Merger, each Cupertino Share outstanding immediately prior to the Effective Time

of the holder thereof, be exchanged for

                                       2

<PAGE>
 
and converted into .81522 (the "Conversion Ratio") of a Bancorp Share. From and 
after the Effective Time of the Merger, each holder of Cupertino Shares 
immediately prior to the Effective Time of the Merger (other than holders of 
Dissenting Shares, as defined below) shall have the right to receive, upon 
surrender of the certificates theretofore representing such Cupertino Shares, 
one or more certificates representing shares of Bancorp Shares equal to the 
number of Cupertino Shares represented by each surrendered certificate 
multiplied by the Conversion Ratio.

     2.2 Fractional Shares. No fractional Bancorp Shares shall be issued in the 
         -----------------
Merger. In lieu thereof, each record holder of Cupertino Shares who would
otherwise be entitled to receive a fractional Bancorp Share shall receive,
subject to prior surrender of certificates representing Cupertino Shares, an
amount in cash equal to the product (calculated to the nearest hundredth)
obtained by multiplying the average of the bid and asked prices quoted by each
brokerage firm acting as a market maker of Mid-Peninsula Shares for a Mid-
Peninsula Share for each of the twenty (20) consecutive trading days up to and
including the last business day of the calendar month end immediately prior to
the Closing Date (as defined in the Agreement), by the fraction of a Bancorp
Share to which such holder would otherwise be entitled. No such holder shall be
entitled to dividends, voting rights, interest, or any other rights in respect
of any such fractional share.

     2.3 Exchange Procedures.
         -------------------

          a. At and after the Effective Time of the Merger, Mid-Peninsula will 
deliver or cause to be delivered to U.S. Stock Transfer Corporation, which shall
serve as exchange agent (the "Exchange Agent"), such number of blank 
certificates representing Bancorp Shares sufficient to issue the number of 
Bancorp Shares issuable in the Merger and an amount of cash sufficient for 
payment of any fractional shares.

          b. As soon as practicable after the Effective Time of the Merger, the 
Exchange Agent will send written notice of exchange procedures to each record 
holder of certificates representing Cupertino Shares converted pursuant to 
Section 2.1(b) of this Merger Agreement.

          c. Upon surrender for cancellation to the Exchange Agent of one or 
more certificates evidencing Cupertino Shares ("Cupertino Certificates"), 
accompanied by a duly executed letter of transmittal in proper form, the 
Exchange Agent shall promptly deliver to each holder of such surrendered 
Cupertino Certificates one or more new certificates representing the appropriate
number of Bancorp Shares ("Bancorp Certificates") to which such holder is 
entitled, together with one or more checks for payment of cash in lieu of 
fractional interests to be issued in respect of the Cupertino Shares so 
surrendered.

          d. Until Cupertino Certificates have been surrendered and exchanged 
for Bancorp Certificates as herein provided, each outstanding Cupertino 
Certificate shall represent, on and after the Effective Time of the Merger, the 
right to receive the number of Bancorp Shares into which the number of Cupertino
Shares shown thereon have been converted. No dividends or other distributions of
any kind which are declared payable to holders of record of the Bancorp

                                       3
<PAGE>
 

Shares after the Effective Time of the Merger will be paid to persons otherwise
entitled to receive the same until such persons have surrendered their Cupertino
Certificates in exchange for Bancorp Certificates in the Manner herein provided,
but upon such surrender, such dividends or other distributions, from and after
the Effective Time of the Merger, will be paid to such persons in accordance
with the terms of such Bancorp Shares. In no event shall the persons entitled to
receive such dividends or other distributions be entitled to receive interest on
such dividends or other distributions.

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

         f.  Any Bancorp Shares delivered to the Exchange Agent and not issued
pursuant hereto at the end of one (1) year from the Effective Time of the Merger
shall be returned to Bancorp, in which event the persons, if any, entitled
thereto shall look only to Bancorp for payment thereof.

         g.  Notwithstanding anything to the contrary set forth herein, if any
holder of Cupertino Shares shall be unable to surrender his or her Cupertino
Certificates because such certificates have been lost or destroyed, such holder
may deliver in lieu thereof an indemnity bond in form and substance and with
surety satisfactory to Bancorp.

         h.  The Exchange Agent shall not be entitled to vote or exercise any
rights of ownership with respect to the Bancorp Shares 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 Bancorp Shares for the
account of the persons entitled thereto. All dividends or distributions, and any
cash to be paid 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 (1) year from the Effective
Time of the Merger, 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 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.

    2.4  Dissenting Shareholders. Notwithstanding the provisions of this 
         -----------------------
Article II to the contrary, any Cupertino Shares held by persons who have 
satisfied the requirements of Chapter 13 of the California General Corporation 
Law (the "GCL") and who have not effectively withdrawn or lost their dissenters'
rights under Chapter 13 (such shares being referred to as "Dissenting Shares"), 
shall  not be converted pursuant to this Merger Agreement, but the holders

thereof shall be entitled only to such rights as are afforded them by Chapter 13
of the GCL.  Each dissenting shareholder who is entitled to payment for his or 
her Cupertino Shares pursuant to Chapter 13 of the GCL shall receive payment in
an amount determined pursuant to Chapter 13 of the GCL.

right of payment to such Senior and Subordinated Debt pursuant to any provision

consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided that the
Company may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders
remain Holders after such record date, provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite principal amount of Outstanding Securities of such
series on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be canceled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of Outstanding Securities of the relevant series on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the
Company, at its own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the
Trustee in writing and to each Holder of Securities of the relevant series in
the manner set forth in Section 1.6.

determining the Holders of Outstanding Securities of any series entitled to join

acceleration referred to in Section 5.2, (iii) any request to institute
proceedings referred to in Section 5.7(2) or (iv) any direction referred to in
Section 5.12, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of 

                                     -13-
<PAGE>
 
Outstanding Securities of such series on such record date, and no other Holders,
shall be entitled to join in such notice, declaration, request or direction,
whether or not such Holders remain Holders after such record date, provided that
no such action shall be effective hereunder unless taken on or prior to the
applicable Expiration Date by Holders of the requisite principal amount of
Outstanding Securities of such series on such record date. Nothing in this
paragraph shall be construed to prevent the Trustee from setting a new record
date for any action for which a record date has previously been set pursuant to
this paragraph (whereupon the record date previously set shall automatically and
with no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities of the relevant
series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Trustee, at the Company's expense, shall cause
notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Company in writing and to each Holder of
Securities of the relevant series in the manner set forth in Section 1.6.

          With respect to any record date set pursuant to this Section, the
party hereto which sets such record dates may designate any day as the
"Expiration Date" and from time to time may change the Expiration Date to any
earlier or later day, provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the other party hereto in
writing, and to each Holder of Securities of the relevant series in the manner
set forth in Section 10.6, on or prior to the existing Expiration Date. If an
Expiration Date is not designated with respect to any record date set pursuant
to this Section, the party hereto which set such record date shall be deemed to
have initially designated the 180th day after such record date as the Expiration
Date with respect thereto, subject to its right to change the Expiration Date as
provided in this paragraph. Notwithstanding the foregoing, no Expiration Date
shall be later than the 180th day after the applicable record date.

          (g) Without limiting the foregoing, a Holder entitled hereunder to
take any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or
more duly appointed agents each of which may do so pursuant to such appointment
with regard to all or any part of such principal amount.

if in writing and mailed, first class postage prepaid, to each Holder affected
by such event, at the address of such Holder as it appears in the Securities
Register, not later than the latest date, and not earlier than the earliest
date, prescribed for the giving of such notice. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

received, hereby promises to pay to __________, or registered assigns, the

for payment and on any overdue principal and (without duplication and to the
extent that payment of such interest is enforceable under applicable law) on any
overdue installment of interest at the rate of ____% per annum, compounded

the basis of twelve 30-day months and a 360-day year. The amount of interest
payable for any partial period shall be computed on the basis of the number of

day which is a Business Day (and without any interest or other payment in
respect of any such delay), except that, if such Business Day is in the next
calendar year, such payment shall be made on the immediately preceding Business
Day, in each case with the same force and effect as if made on the date the

Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest installment, which shall
be[insert Record Date] next preceding such Interest Payment Date. Any such
interest installment not so punctually paid or duly provided for shall forthwith
cease to be payable to the Holder on such Regular Record Date and may either be
paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date for
the payment of such Defaulted Interest to be fixed by the Trustee, notice
whereof shall be given to Holders of Securities of this series not less than
_____ days prior to such Special Record Date, or be paid at any time in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities of this series may be listed, and upon such
notice as may be required by such exchange, all as more fully provided in said
Indenture.

respect to each deferral period (each an "Extension Period"), (during which
Extension Periods the Company shall have the right to make partial payments of
interest on any Interest Payment Date, and at the end of which the Company shall

further, that during any such Extension Period, the Company shall not, and shall
not permit any Subsidiary of the Company to, (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire or make a liquidation payment
with respect to, any of the Company's capital stock (which includes common and
preferred stock), or (ii) make any payment of principal of or interest or
premium, if any, on or repay, repurchase or redeem any debt security of the
Company (including Securities issued by the Company pursuant to the Indenture
other than the Securities represented by this certificate) that ranks pari passu
with or junior in interest to this Security, or (iii) make any guarantee
payments with respect to any guarantee by the Company of the debt securities of
any Subsidiaries of the Company (if such guarantee ranks pari passu in all
respects with or junior in interest to this Security (other than (a) dividends

such Extension Period, the Company may further extend such Extension Period,
provided that such extension does not cause such Extension Period to exceed
_______ consecutive interest payment periods or to extend beyond the Stated
Maturity. Upon the termination of any such Extension Period and upon the payment
of all amounts then due on any Interest Payment Date, and subject to the
foregoing limitation, the Company may elect to begin a new Extension Period. No
interest shall be due and payable during an Extension Period except at the end
thereof. The Company shall give the Trustee, the Property Trustee and the
Administrative Trustees of [NAME OF TRUST] notice of its election to begin any
Extension Period at least ___ Business Days prior to the earlier of (i) the date
on which Distributions on the Preferred Securities would be payable except for
the election to begin such Extension Period, or (ii) the date the Administrative
Trustees are required to give notice to the New York Stock Exchange, the Nasdaq

Security will be made at the office or agency of the Trustee or at the office of
such paying agent or paying agents as the Company may designate from time to
time, maintained for that purpose in the United States, in such coin or currency

payment of public and private debts; provided, however, that at the option of
the Company payment of interest may be made (i) by check mailed to the address
of the Person entitled thereto as such address shall appear in the Securities
Register or (ii) by transfer to an account maintained by the person entitled
thereto, in immediately available funds, at such place and to such account as

right of payments to the prior payment in full of all Senior and Subordinated
Debt, and this Security is issued subject to the provisions of the Indenture
with respect thereto.  Each Holder of this Security, by accepting the same, (a)
agrees to and shall be bound by such provisions, (b) authorizes and directs the
Trustee on his behalf to take such actions as may be necessary or appropriate to
effectuate the subordination so provided and (c) appoints the Trustee his

          All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided herein or in
or pursuant to such Board Resolution and set forth in such Officers' Certificate
or in any such indenture supplemental hereto.

          If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

          The Securities shall be subordinated in right of payment to Senior and
Subordinated Debt as provided in Article XIII.

Section 3.2.  Denominations.

          The Securities of each series shall be in registered form without
coupons and shall be issuable in minimum denominations of $25 and integral
multiples of $25 in excess thereof, unless otherwise specified as contemplated
by Section 3.1.

Section 3.3.  Execution, Authentication, Delivery and Dating.

          The Securities shall be executed on behalf of the Company by its
President or one of its Vice Presidents under its corporate seal reproduced or
impressed thereon and attested by its Secretary or one of its Assistant
Secretaries. The signature of any of these officers on the Securities may be
manual or facsimile.

          Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities. At any time and from time to
time after the execution and delivery of this Indenture, the Company may deliver
Securities of any series executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities. If the form or terms of
the Securities of the series have been established by or pursuant to one or more
Board Resolutions as permitted by Sections 2.1 and 3.1, in authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities, the Trustee shall be entitled to receive, and
(subject to Section 6.1) shall be fully protected in relying upon, an Opinion of
Counsel stating,

                                     -28-
<PAGE>
 
          (1) if the form of such Securities has been established by or pursuant
 to Board Resolution as permitted by Section 2.1, that such form has been
 established in conformity with the provisions of this Indenture;

          (2) if the terms of such Securities have been established by or
 pursuant to Board Resolution as permitted by Section 3.1, that such terms have
 been established in conformity with the provisions of this Indenture; and

          (3) that such Securities, when authenticated and delivered by the
 Trustee and issued by the Company in the manner and subject to any conditions
 specified in such Opinion of Counsel, will constitute valid and legally binding
 obligations of the Company enforceable in accordance with their terms, subject
 to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
 similar laws of general applicability relating to or affecting creditors'
 rights and to general equity principles.

          If such form or terms have been so established, the Trustee shall not
be required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

          Notwithstanding the provisions of Section 3.1 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 3.1 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

          Each Security shall be dated the date of its authentication.

          No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose, unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by the manual signature of one of its authorized
officers, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder. Notwithstanding the foregoing, if any Security shall have
been authenticated and delivered hereunder but never issued and sold by the
Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 3.9, for all purposes of this Indenture such
Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

Section 3.4.  Temporary Securities.

          Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any denomination, substantially of the
tenor of the definitive Securities of such series in lieu of which they are
issued and with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Securities may determine, as evidenced
by their execution of such Securities.

          If temporary Securities of any series are issued, the Company will
cause definitive Securities of such series to be prepared without unreasonable
delay.  After the preparation of definitive Securities, the temporary Securities
shall be exchangeable for definitive Securities upon surrender of the temporary
Securities at the office or agency of the Company designated for that purpose
without charge to the Holder.  Upon surrender for cancellation of any one or
more temporary Securities, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor one or more definitive Securities
of the same series of authorized denominations having the same Original Issue
Date and Stated Maturity and having the same terms as such temporary Securities.
Until so exchanged, the temporary Securities of any series shall in all respects
be entitled to the same benefits under this Indenture as definitive Securities
of such series.

Section 3.5.  Registration, Transfer and Exchange.

          The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register in which, subject to such reasonable regulations as it
may prescribe, the Company shall provide for the registration of Securities and
of transfers of Securities.  Such register is herein sometimes referred to as
the "Securities Register." The Trustee is hereby appointed "Securities
Registrar" for the purpose of registering Securities and transfers of Securities
as herein provided.

          Upon surrender for registration of transfer of any Security at the
office or agency of the Company designated for that purpose the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of the same
series of any authorized denominations, of a like aggregate principal amount, of
the same Original Issue Date and Stated Maturity and having the same terms.

          At the option of the Holder, Securities may be exchanged for other
Securities of the same series of any authorized denominations, of a like
aggregate principal amount, of the same Original Issue Date and Stated Maturity
and having the same terms, upon surrender of the Securities to be exchanged at
such office or agency.  

                                     -30-
<PAGE>
 
Whenever any securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive.

          All Securities issued upon any transfer or exchange of Securities
shall be the valid obligations of the Company, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Securities
surrendered upon such transfer or exchange.

          Every Security presented or surrendered for transfer or exchange shall
(if so required by the Company or the Securities Registrar) be duly endorsed, or
be accompanied by a written instrument of transfer in form satisfactory to the
Company and the Securities Registrar, duly executed by the Holder thereof or his
attorney duly authorized in writing.

          No service charge shall be made to a Holder for any transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Securities.

          No service charge shall be made to a Holder for any transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Securities.

          The provisions of Clauses (1), (2), (3) and (4) below shall apply only
to Global Securities:

          (1) Each Global Security authenticated under this Indenture shall be
 registered in the name of the Depositary designated for such Global Security or
 a nominee thereof and delivered to such Depositary or a nominee thereof or
 custodian therefor, and each such Global Security shall constitute a single
 Security for all purposes of this Indenture.

          (2) Notwithstanding any other provision in this Indenture, no Global
 Security may be exchanged in whole or in part for Securities registered, and no
 transfer of a Global Security in whole or in part may be registered, in the
 name of any Person other than the Depositary for such Global Security or a
 nominee thereof unless (A) such Depositary (i) has notified the Company that it
 is unwilling or unable to continue as Depositary for such Global Security or
 (ii) has ceased to be a clearing agency registered under the Exchange Act at a
 time when the Depositary is required to be so registered to act as depositary,
 in each case unless the Company has approved a successor Depositary within 90
 days, (B) there shall have occurred and be continuing an Event of Default with
 respect to such 

                                     -31-
<PAGE>
 
 Global Security, (C) the Company in its sole discretion determines that such
 Global Security will be so exchangeable or transferable or (D) there shall
 exist such circumstances, if any, in addition to or in lieu of the foregoing as
 have been specified for this purpose as contemplated by Section 3.1.

          (3) Subject to Clause (2) above, any exchange of a Global Security for
 other Securities may be made in whole or in part, and all Securities issued in
 exchange for a Global Security or any portion thereof shall be registered in
 such names as the Depositary for such Global Security shall direct.

          (4) Every Security authenticated and delivered upon registration of
 transfer of, or in exchange for or in lieu of, a Global Security or any portion
 thereof, whether pursuant to this Section, Section 3.4, 3.6, 9.6 or 11.6 or
 otherwise, shall be authenticated and delivered in the form of, and shall be, a
 Global Security, unless such Security is registered in the name of a Person
 other than the Depositary for such Global Security or a nominee thereof.

          Neither the Company nor the Trustee shall be required, pursuant to the
provisions of this Section, (a) to issue, transfer or exchange any Security of
any series during a period beginning at the opening of business 15 days before
the day of selection for redemption of Securities pursuant to Article XI and
ending at the close of business on the day of mailing of notice of redemption or
(b) to transfer or exchange any Security so selected for redemption in whole or
in part, except, in the case of any Security to be redeemed in part, any portion
thereof not to be redeemed.

Section 3.6.  Mutilated, Destroyed, Lost and Stolen Securities.

          If any mutilated Security is surrendered to the Trustee together with
such security or indemnity as may be required by the Company or the Trustee to
save each of them harmless, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a new Security of the same issue
and series of like tenor and principal amount, having the same Original Issue
Date and Stated Maturity, and bearing a number not contemporaneously
outstanding.

          If there shall be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
Security, and (ii) such security or indemnity as may be required by them to save
each of them harmless, then, in the absence of notice to the Company or the
Trustee that such Security has been acquired by a bona fide purchaser, the
Company shall execute and upon its request the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of the same issue and series of like tenor and principal amount, having the same
Original Issue Date and Stated Maturity as such destroyed, lost or stolen
Security, and bearing a number not contemporaneously outstanding.

                                     -32-
<PAGE>
 
          In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

          Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

          Every new Security issued pursuant to this Section in lieu of any
destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities duly issued hereunder.

          The provisions of this Section 3.6 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 3.7.  Payment of Interest; Interest Rights Preserved.

          Interest on any Security of any series which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date, shall be
paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest in respect of Securities of such series, except that, unless
otherwise provided in the Securities of such series, interest payable on the
Stated Maturity of the principal of a Security shall be paid to the Person to
whom principal is paid.  The initial payment of interest on any Security of any
series which is issued between a Regular Record Date and the related Interest
Payment Date shall be payable as provided in such Security or in the Board
Resolution pursuant to Section 3.1 with respect to the related series of
Securities.

          Any interest on any Security which is payable, but is not timely paid
or duly provided for, on any Interest Payment Date for Securities of such series
(herein called "Defaulted Interest"), shall forthwith cease to be payable to the
registered Holder on the relevant Regular Record Date by virtue of having been
such Holder, and such Defaulted Interest may be paid by the Company, at its
election in each case, as provided in Clause (1) or (2) below:

          (1) The Company may elect to make payment of any Defaulted Interest to
the Persons in whose names the Securities of such series in respect of which
interest is in default (or their respective Predecessor Securities) are
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest, which shall be fixed in the following manner.  The
Company shall notify the Trustee in 

                                     -33-
<PAGE>
 
writing of the amount of Defaulted Interest proposed to be paid on each Security
and the date of the proposed payment, and at the same time the Company shall
deposit with the Trustee an amount of money equal to the aggregate amount
proposed to be paid in respect of such Defaulted Interest or shall make
arrangements satisfactory to the Trustee for such deposit prior to the date of
the proposed payment, such money when deposited to be held in trust for the
benefit of the Persons entitled to such Defaulted Interest as in this Clause
provided. Thereupon, the Trustee shall fix a Special Record Date for the payment
of such Defaulted Interest which shall be not more than 15 days and not less
than 10 days prior to the date of the proposed payment and not less than 10 days
after the receipt by the Trustee of the notice of the proposed payment. The
Trustee shall promptly notify the Company of such Special Record Date and, in
the name and at the expense of the Company, shall cause notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefor to be
mailed, first class, postage prepaid, to each Holder of a Security of such
series at the address of such Holder as it appears in the Securities Register
not less than 10 days prior to such Special Record Date. The Trustee may, in its
discretion, in the name and at the expense of the Company, cause a similar
notice to be published at least once in a newspaper, customarily published in
the English language on each Business Day and of general circulation in the
[BOROUGH OF ______, THE CITY OF ______], but such publication shall not be a
condition precedent to the establishment of such Special Record Date. Notice of
the proposed payment of such Defaulted Interest and the Special Record Date
therefor having been mailed as aforesaid, such Defaulted Interest shall be paid
to the Persons in whose names the Securities of such series (or their respective
Predecessor Securities) are registered on such Special Record Date and shall no
longer be payable pursuant to the following Clause (2).

          (2) The Company may make payment of any Defaulted Interest in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities of the series in respect of which interest is
in default may be listed and, upon such notice as may be required by such
exchange (or by the Trustee if the Securities are not listed), if, after notice
given by the Company to the Trustee of the proposed payment pursuant to this
Clause, such payment shall be deemed practicable by the Trustee.

          Subject to the foregoing provisions of this Section 3.7, each Security
delivered under this Indenture upon transfer of or in exchange for or in lieu of
any other Security shall carry the rights to interest accrued and unpaid, and to
accrue, which were carried by such other Security.

Section 3.8.  Persons Deemed Owners.

          The Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name any Security is registered as the owner of
such 

                                     -34-
<PAGE>
 
Security for the purpose of receiving payment of principal of and (subject to
Section 3.7) any interest on such Security and for all other purposes
whatsoever, whether or not such Security be overdue, and neither the Company,
the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary.

Section 3.9.  Cancellation.

          All Securities surrendered for payment, redemption, transfer or
exchange shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee, and any such Securities and Securities surrendered
directly to the Trustee for any such purpose shall be promptly canceled by it.
The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and all Securities so delivered
shall be promptly canceled by the Trustee.  No Securities shall be authenticated
in lieu of or in exchange for any Securities canceled as provided in this
Section, except as expressly permitted by this Indenture.  All canceled
Securities shall be destroyed by the Trustee and the Trustee shall deliver to
the Company a certificate of such destruction.

Section 3.10.  Computation of Interest.

          Except as otherwise specified as contemplated by Section 3.1 for
Securities of any series, interest on the Securities of each series for any
period shall be computed on the basis of a 360-day year of twelve 30-day months
and interest on the Securities of each series for any partial period shall be
computed on the basis of the number of days elapsed in a 360-day year of twelve
30-day months.

Section 3.11.  Deferrals of Interest Payment Dates.

          If specified as contemplated by Section 2.1 or Section 3.1 with
respect to the Securities of a particular series, so long as no Event of Default
has occurred and is continuing, the Company shall have the right, at any time
during the term of such series, from time to time to defer the payment of
interest on such Securities for such period or periods as may be specified as
contemplated by Section 3.1 (each, an "Extension Period") during which Extension
Periods the Company shall have the right to make partial payments of interest on
any Interest Payment Date. No Extension Period shall end on a date other than an
Interest Payment Date. At the end of any such Extension Period the Company shall
pay all interest then accrued and unpaid on the Securities (together with
Additional Interest thereon, if any, at the rate specified for the Securities of
such series to the extent permitted by applicable law); provided, however, that
no Extension Period shall extend beyond the Stated Maturity of the principal of
the Securities of such series; provided, further, that during any such Extension
Period, the Company shall not, and shall not permit any Subsidiary to,
(i) declare or pay any dividends or distributions on, or 

                                     -35-
<PAGE>
 
redeem, purchase, acquire or make a liquidation payment with respect to, any of
the Company's capital stock (which includes common and preferred stock), or (ii)
make any payment of principal of or interest or premium, if any, on or repay,
repurchase or redeem any debt securities of the Company (including Securities
other than the Securities of such series) that ranks pari passu in all respects
with or junior in interest to the Securities of such series or make any
guarantee payments with respect to any guarantee by the Company of the debt
securities of any Subsidiary of the Company if such guarantee rank pari passu in
all respects with or junior in interest to the securities of such series (other
than (a) dividends or distributions in capital stock of the Company (which
includes common and preferred stock), (b) any declaration of a dividend in
connection with the implementation of a stockholders' rights plan, or the
redemption or repurchase of any such rights pursuant thereto, (c) payments under
the GBB Guarantee related to the Preferred Securities issued by the GBB Trust
holding Securities of such series, and (d) purchases of Common Stock related to
the issuance of Common Stock or rights under any of the Company's benefit plans
for its directors, officers or employees). Prior to the termination of any such
Extension Period, the Company may further extend such Extension Period, provided
that such extension does not cause such Extension Period to extend beyond the
Stated Maturity of the principal of such Securities. Upon termination of any
Extension Period and upon the payment of all accrued and unpaid interest and any
Additional Interest then due on any Interest Payment Date, the Company may elect
to begin a new Extension Period, subject to the above requirements. No interest
shall be due and payable during an Extension Period, except at the end thereof.
The Company shall give the Trustee, the Property Trustee and the Administrative
Trustees of the GBB Trust holding Securities of such series notice of its
election of any Extension Period (or an extension thereof) at least one Business
Day prior to the earlier of (i) the next succeeding date on which Distributions
on the Preferred Securities of such GBB Trust would be payable except for the
election to begin or extend such Extension Period or (ii) the date the
Administrative Trustees are required to give notice to the New York Stock
Exchange, the Nasdaq National Market or other applicable stock exchange or
automated quotation system on which the Preferred Securities are then listed or
quoted or to holders of such Preferred Securities of the record date or (iii)
the date such Distributions are payable, but in any event not less than one
Business Day prior to such record date. The Trustee shall give notice of the
Company's election to begin a new Extension Period to the holders of the Junior
Subordinated Debentures. There is no limitation on the number of times that the
Company may elect to begin an Extension Period.

          The Trustee shall promptly give notice of the Company's election to
begin any such Extension Period to the Holders of the Outstanding Securities of
such series.

Section 3.12.  Right of Set-Off.

          With respect to the Securities of a series issued to a GBB Trust,
notwithstanding anything to the contrary in the Indenture, the Company shall
have the right to set-off any payment it is otherwise required to make
thereunder in respect of any such Security to the extent the Company has
theretofore made, or is concurrently on the date of such payment making, a
payment under the Guarantee Agreement relating to such Security or under Section
5.8 of the Indenture.

Section 3.13.  Agreed Tax Treatment.

          Each Security issued hereunder shall provide that the Company and, by
its acceptance of a Security or a beneficial interest therein, the Holder of,
and any Person that acquires a beneficial interest in, such Security agree that
for United States Federal, state and local tax purposes it is intended that such
Security constitute indebtedness.

Section 3.14.   Shortening of Stated Maturity.

          If specified as contemplated by Section 2.1 or Section 3.1 with
respect to the Securities of a particular series, the Company shall have the
right to shorten the Stated Maturity of the principal of the Securities of such
series at any time to any date not earlier than the first date on which the
Company has the right to redeem the Securities of such series.


Section 3.15.  CUSIP Numbers.

          The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers.

Section 4.1.  Satisfaction and Discharge of Indenture.

          This Indenture shall, upon Company Request, cease to be of further
effect (except as to any surviving rights of registration of transfer or
exchange of Securities herein expressly provided for and as otherwise provided
in this Section 4.1) and the Trustee, on demand of and at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and

                                   REMEDIES

Section 5.1  Events of Default.

          "Event of Default", wherever used herein with respect to the
Securities of any series, means any one of the following events (whatever the
reason for such Event of Default and whether it shall be voluntary or
involuntary or be effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

          (1) default in the payment of any interest upon any Security of that
series, including any Additional Interest in respect thereof, when it becomes
due and payable, and continuance of such default for a period of 30 days
(subject to the deferral of any due date in the case of an Extension Period); or

          (2) default in the payment of the principal of (or premium, if any,
on) any Security of that series at its Maturity; or

                                     -39-
<PAGE>
 
          (3) default in the performance, or breach, in any material respect, of
any covenant or warranty of the Company in this Indenture (other than a covenant
or warranty a default in the performance of which or the breach of which is
elsewhere in this Section 5.1 specifically dealt with), and continuance of such
default or breach for a period of 60 days after there has been given, by
registered or certified mail, to the Company by the Trustee or to the Company
and the Trustee by the Holders of at least 25% in principal amount of the
Outstanding Securities of that series a written notice specifying such default
or breach and requiring it to be remedied; or

          (4) the entry of a decree or order by a court having jurisdiction in
the premises adjudging the Company a bankrupt or insolvent, or approving as
properly filed a petition seeking reorganization, arrangement, adjustment or
composition of or in respect of the Company under any applicable Federal or
State bankruptcy, insolvency, reorganization or other similar law, or appointing
a receiver, liquidator, assignee, trustee, sequestrator (or other similar
official) of the Company or of any substantial part of its property or ordering
the winding up or liquidation of its affairs, and the continuance of any such
decree or order unstayed and in effect for a period of 60 consecutive days; or

          (5) the institution by the Company of proceedings to be adjudicated a
bankrupt or insolvent, or the consent by it to the institution of bankruptcy or
insolvency proceedings against it, or the filing by it of a petition or answer
or consent seeking reorganization or relief under any applicable Federal or
State bankruptcy, insolvency, reorganization or other similar law, or the
consent by it to the filing of any such petition or to the appointment of a
receiver, liquidator, assignee, trustee, sequestrator (or other similar
official) of the Company or of any substantial part of its property, or the
making by it of an assignment for the benefit for creditors, or the admission by
it in writing of its inability to pay its debts generally as they become due and
its willingness to be adjudicated a bankrupt, or the taking of corporate action
by the Company in furtherance of any such action; or

          (6) any other Event of Default provided with respect to Securities of
that series.

Section 5.2.  Acceleration of Maturity; Rescission and Annulment.

          If an Event of Default (other than an Event of Default specified in
Section 5.1(4) or 5.1(5)) with respect to Securities of any series at the time
Outstanding occurs and is continuing, then and in every such case the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount (or, if the
Securities of that series are Discount Securities, such portion of the principal
amount as may be specified in the terms of that series) of all the Securities of
that series to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by 

                                     -40-
<PAGE>
 
Holders), provided that, in the case of the Securities of a series issued to a
GBB Trust, if, upon an Event of Default, the Trustee or the Holders of not less
than 25% in principal amount of the Outstanding Securities of that series fail
to declare the principal of all the Securities of that series to be immediately
due and payable, the holders of at least 25% in aggregate liquidation amount of
the corresponding series of Preferred Securities then outstanding shall have
such right by a notice in writing to the Company and the Trustee; and upon any
such declaration such principal amount (or specified portion thereof) of and the
accrued interest (including any Additional Interest) on all the Securities of
such series shall become immediately due and payable. Payment of principal and
interest (including any Additional Interest) on such Securities shall remain
subordinated to the extent provided in Article XIII notwithstanding that such
amount shall become immediately due and payable as herein provided. If an Event
of Default specified in Section 5.1(4) or 5.1(5) with respect to Securities of
any series at the time Outstanding occurs, the principal amount of all the
Securities of that series (or, if the Securities of that series are Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms of that series) shall automatically, and without any
declaration or other action on the part of the Trustee or any Holder, become
immediately due and payable.

          At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if:

          (1) the Company has paid or deposited with the Trustee a sum
sufficient to pay:

          (A) all overdue installments of interest (including any Additional
Interest) on all Securities of that series,

          (B) the principal of (and premium, if any, on) any Securities of that
series which have become due otherwise than by such declaration of acceleration
and interest thereon at the rate borne by the Securities, and

          (C) all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel; and

          (2) all Events of Default with respect to Securities of that series,
other than the non-payment of the principal of Securities of that series which
has become 

                                     -41-
<PAGE>
 
due solely by such acceleration, have been cured or waived as provided in
Section 5.13.

          In the case of Securities of a series issued to a GBB Trust, the
holders of a majority in aggregate Liquidation Amount (as defined in the Trust
Agreement under which such GBB Trust is formed) of the related series of
Preferred Securities issued by such GBB Trust shall also have the right to
rescind and annul such declaration and its consequences by written notice to the
Company and the Trustee subject to the satisfaction of the conditions set forth
in Clauses (1) and (2) above of this Section 5.2.

          No such rescission shall affect any subsequent default or impair any
right consequent thereon.

Section 5.3.  Collection of Indebtedness and Suits for Enforcement by Trustee.

          The Company covenants that if:

          (1) default is made in the payment of any installment of interest
(including any Additional Interest) on any Security when such interest becomes
due and payable and such default continues for a period of 30 days, or

          (2) default is made in the payment of the principal of (and premium,
if any, on) any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities, the whole amount then due and payable
on such Securities for principal, including any sinking fund payment or
analogous obligations (and premium, if any) and interest (including any
Additional Interest); and, in addition thereto, all amounts owing the Trustee
under Section 6.7.

          If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon the Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Securities, wherever
situated.

          If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this 

                                     -42-
<PAGE>
 
Indenture or in aid of the exercise of any power granted herein, or to enforce
any other proper remedy.

Section 5.4.  Trustee May File Proofs of Claim.

          In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors,

          (a) the Trustee (irrespective of whether the principal of the
Securities of any series shall then be due and payable as therein expressed or
by declaration or otherwise and irrespective of whether the Trustee shall have
made any demand on the Company for the payment of overdue principal (and
premium, if any) or interest (including any Additional Interest)) shall be
entitled and empowered, by intervention in such proceeding or otherwise,

          (i) to file and prove a claim for the whole amount of principal (and
premium, if any) and interest (including any Additional Interest) owing and
unpaid in respect to the Securities and to file such other papers or documents
as may be necessary or advisable and to take any and all actions as are
authorized under the Trust Indenture Act in order to have the claims of the
Holders and any predecessor to the Trustee under Section 6.7 allowed in any such
judicial proceedings; and

          (ii) in particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same in accordance with Section 5.6; and

          (b) any custodian, receiver, assignee, trustee, liquidator,
sequestrator (or other similar official) in any such judicial proceeding is
hereby authorized by each Holder to make such payments to the Trustee for
distribution in accordance with Section 5.6, and in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due to it and any predecessor Trustee under Section 6.7.

          Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

Section 5.5.  Trustee May Enforce Claim Without Possession of Securities.

          All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of all the amounts owing the Trustee and any
predecessor Trustee under Section 6.7, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

Section 5.6.  Application of Money Collected.

          Any money or property collected or to be applied by the Trustee with
respect to a series of Securities pursuant to this Article shall be applied in
the following order, at the date or dates fixed by the Trustee and, in case of
the distribution of such money or property on account of principal (or premium,
if any) or interest (including any Additional Interest), upon presentation of
the Securities and the notation thereon of the payment if only partially paid
and upon surrender thereof if fully paid:

          FIRST:  To the payment of all amounts due the Trustee and any
predecessor Trustee under Section 6.7;

          SECOND:  Subject to Article XIII, to the payment of the amounts then
due and unpaid upon such series of Securities for principal (and premium, if
any) and interest (including any Additional Interest), in respect of which or
for the benefit of which such money has been collected, ratably, without
preference or priority of any kind, according to the amounts due and payable on
such series of Securities for principal (and premium, if any) and interest
(including any Additional Interest), respectively; and

          THIRD:  The balance, if any, to the Person or Persons entitled
thereto.

Section 5.7.  Limitation on Suits.

          No Holder of any Securities of any series shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture
or for the appointment of a receiver, assignee, trustee, liquidator,
sequestrator (or other similar official) or for any other remedy hereunder,
unless:

          (1) such Holder has previously given written notice to the Trustee of
a continuing Event of Default with respect to the Securities of that series;

                                     -44-
<PAGE>
 
          (2) the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default in its own
name as Trustee hereunder;

          (3) such Holder or Holders have offered to the Trustee reasonable
indemnity against the costs, expenses and liabilities to be incurred in
compliance with such request:

          (4) the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity has failed to institute any such proceeding; and

          (5) no direction inconsistent with such written request has been given
to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing itself of, any
provision of this Indenture to affect, disturb or prejudice the rights of any
other Holders of Securities, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable
benefit of all such Holders.

Section 5.8.  Unconditional Right of Holders to Receive Principal, Premium and
              Interest; Direct Action by Holders of Preferred Securities.

          Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right which is absolute and unconditional to receive
payment of the principal of (and premium, if any) and (subject to Section 3.7)
interest (including any Additional Interest) on such Security on the respective
Stated Maturities expressed in such Security (or, in the case of redemption, on
the Redemption Date) and to institute suit for the enforcement of any such
payment, and such right shall not be impaired without the consent of such
Holder. In the case of Securities of a series issued to a GBB Trust, any holder
of the corresponding series of Preferred Securities issued by such GBB Trust
shall have the right, upon the occurrence of an Event of Default described in
Section 5.1(1) or 5.1(2), to institute a suit directly against the Company for
enforcement of payment to such holder of principal of (premium, if any) and
(subject to Section 3.7) interest (including any Additional Interest) on the
Securities having a principal amount equal to the aggregate Liquidation Amount
(as defined in the Trust Agreement under which such GBB Trust is formed) of such
Preferred Securities of the corresponding series held by such holder.

Section 5.9.  Restoration of Rights and Remedies.

          If the Trustee, any Holder or any holder of Preferred Securities has
instituted any proceeding to enforce any right or remedy under this Indenture
and such proceeding has been discontinued or abandoned for any reason, or has
been determined adversely to the Trustee, such Holder or such holder of
Preferred Securities, then and in every such case the Company, the Trustee, the
Holders and such holder of Preferred Securities shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee, the Holders and the holders of Preferred Securities shall continue as
though no such proceeding had been instituted.

Section 5.10.  Rights and Remedies Cumulative.

          Except as otherwise provided in the last paragraph of Section 3.6, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise.  The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

Section 5.11.  Delay or Omission Not Waiver.

          No delay or omission of the Trustee, any Holder of any Security or any
holder of any Preferred Security to exercise any right or remedy accruing upon
any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein.

          Every right and remedy given by this Article or by law to the Trustee
or to the Holders and the right and remedy given to the holders of Preferred
Securities by Section 5.8 may be exercised from time to time, and as often as
may be deemed expedient, by the Trustee, the Holders or the holders of Preferred
Securities, as the case may be.

Section 5.12.  Control by Holders.

          The Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee, with respect to the
Securities of such series, provided that:

                                     -46-
<PAGE>
 
          (1) such direction shall not be in conflict with any rule of law or
with this Indenture,

          (2) the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction, and

          (3) subject to the provisions of Section 6.1, the Trustee shall have
the right to decline to follow such direction if a Responsible Officer or
Officers of the Trustee shall, in good faith, determine that the proceeding so
directed would be unjustly prejudicial to the Holders not joining in any such
direction or would involve the Trustee in personal liability.

Section 5.13.  Waiver of Past Defaults.

          The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series and, in the case of any Securities of a
series issued to a GBB Trust, the holders of Preferred Securities issued by such
GBB Trust may waive any past default hereunder and its consequences with respect
to such series except a default:

          (1) in the payment of the principal of (or premium, if any) or
interest (including any Additional Interest) on any Security of such series, or

          (2) in respect of a covenant or provision hereof which under
ArticleuIX cannot be modified or amended without the consent of the Holder of
each Outstanding Security of such series affected.

          Any such waiver shall be deemed to be on behalf of the Holders of all
the Securities of such series or, in the case of a waiver by holders of
Preferred Securities issued by such GBB Trust, by all holders of Preferred
Securities issued by such GBB Trust.

          Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

Section 5.14.  Undertaking for Costs.

          All parties to this Indenture agree, and each Holder of any Security
by his acceptance thereof shall be deemed to have agreed, that any court may in
its discretion require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs 

                                     -47-
<PAGE>
 
of such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; but the provisions of this Section shall not apply to any
suit instituted by the Trustee, to any suit instituted by any Holder, or group
of Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities of any series, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium, if any) or
interest (including any Additional Interest) on any Security on or after the
respective Stated Maturities expressed in such Security.

Section 5.15.  Waiver of Usury, Stay or Extension Laws.

          The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any usury, stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                  THE TRUSTEE

Section 6.1.  Certain Duties and Responsibilities.

          (a) Except during the continuance of an Event of Default;

          (1) the Trustee undertakes to perform such duties and only such duties
as are specifically set forth in this Indenture, and no implied covenants or
obligations shall be read into this Indenture against the Trustee; and

          (2) in the absence of bad faith on its part, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture; but in the case of
any such certificates or opinions which by any provisions hereof are
specifically required to be furnished to the Trustee, the Trustee shall be under
a duty to examine the same to determine whether or not they conform to the
requirements of this Indenture.

                                     -48-
<PAGE>
 
          (b) In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
his own affairs.

          (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct except that

          (1) this Subsection shall not be construed to limit the effect of
Subsection (a) of this Section;

          (2) the Trustee shall not be liable for any error of judgment made in
good faith by a Responsible Officer, unless it shall be proved that the Trustee
was negligent in ascertaining the pertinent facts; and

          (3) the Trustee shall not be liable with respect to any action taken
or omitted to be taken by it in good faith in accordance with the direction of
Holders pursuant to Section 5.12 relating to the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred upon the Trustee, under this Indenture with respect
to the Securities of such series.

          (d) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if there shall be reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

          (e) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section 6.1.

Section 6.2.  Notice of Defaults.

          Within 90 days after actual knowledge by a Responsible Officer of the
Trustee of the occurrence of any default hereunder with respect to the
Securities of any series, the Trustee shall transmit by mail to all Holders of
Securities of such series, as their names and addresses appear in the Securities
Register, notice of such default, unless such default shall have been cured or
waived; provided, however, that, except in the case of a default in the payment
of the principal of (or premium, if any) or interest (including any Additional

<PAGE>
 
determine to make such inquiry or investigation, it shall be entitled to examine

Section 6.4.  Not Responsible for Recitals or Issuance of Securities.

          The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and neither the Trustee nor any Authenticating Agent assumes any
responsibility for their correctness.  The Trustee makes no representations as
to the validity or sufficiency of this Indenture or of the Securities.  Neither
the Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of the Securities or the proceeds thereof.

Section 6.5.  May Hold Securities.

          The Trustee, any Authenticating Agent, any Paying Agent, any
Securities Registrar or any other agent of the Company, in its individual or any
other capacity, may become the owner or pledgee of Securities and, subject to
Sections 6.8 and 6.13, may otherwise deal with the Company with the same rights
it would have if it were not Trustee, Authenticating Agent, Paying Agent,
Securities Registrar or such other agent.

Section 6.6.  Money Held in Trust.

          Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law.  The Trustee shall be

The Company agrees

          (1) to pay to the Trustee from time to time compensation for all
services rendered by it hereunder in such amounts as the Company and the Trustee

provision of law in regard to the compensation of a trustee of an express
trust);

                                     -51-
<PAGE>
 
          (2) to reimburse the Trustee upon its request for all reasonable
expenses, disbursements and advances incurred or made by the Trustee in
accordance with any provision of this Indenture (including the reasonable
compensation and the expenses and disbursements of its agents and counsel),
except any such expense, disbursement or advance as may be attributable to its
negligence or bad faith; and

          (3) to indemnify the Trustee for, and to hold it harmless against, any
loss, liability or expense (including the reasonable compensation and the
expenses and disbursements of its agents and counsel) incurred without
negligence or bad faith, arising out of or in connection with the acceptance or
administration of this trust or the performance of its duties hereunder,
including the costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers or
duties hereunder.  This indemnification shall survive the termination of this
Agreement.

          To secure the Company's payment obligations in this Section 6.7, the
Company and the Holders agree that the Trustee shall have a lien prior to the
Securities on all money or property held or collected by the Trustee.  Such lien
shall survive the satisfaction and discharge of this Indenture.

          When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 5.1(4) or (5) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under the Bankruptcy Reform Act of 1978 or any successor statute.

Section 6.8.  Disqualification; Conflicting Interests.

          The Trustee for the Securities of any series issued hereunder shall be
subject to the provisions of Section 310(b) of the Trust Indenture Act.  Nothing
herein shall prevent the Trustee from filing with the Commission the application
referred to in the second to last paragraph of said Section 301(b).

Section 6.9.  Corporate Trustee Required; Eligibility.

There shall at all times be a Trustee hereunder which shall be

          (a) a corporation organized and doing business under the laws of the
United States of America or of any State or Territory or the District of
Columbia, authorized under such laws to exercise corporate trust powers and
subject to supervision or examination by Federal, State, Territorial or District
of Columbia authority, or

          (b) a corporation or other Person organized and doing business under
the laws of a foreign government that is permitted to act as Trustee pursuant to
a 

                                     -52-
<PAGE>
 
rule, regulation or order of the Commission, authorized under such laws to
exercise corporate trust powers, and subject to supervision or examination by
authority of such foreign government or a political subdivision thereof
substantially equivalent to supervision or examination applicable to United
States institutional trustees,

in either case having a combined capital and surplus of at least $50,000,000,
subject to supervision or examination by Federal or State authority.  If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid supervising or examining authority, then,
for the purposes of this Section 6.9, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published.  If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section
6.9, it shall resign immediately in the manner and with the effect hereinafter
specified in this Article VI.  Neither the Company nor any Person directly or
indirectly controlling, controlled by or under common control with the Company
shall serve as Trustee for the Securities of any series issued hereunder.

Section 6.10.  Resignation and Removal; Appointment of Successor.

          (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article VI shall become effective until the
acceptance of appointment by the successor Trustee under Section 6.11.

          (b) The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Company.  If an
instrument of acceptance by a successor Trustee shall not have been delivered to
the Trustee within 30 days after the giving of such notice of resignation, the
resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

          (c) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series, delivered to the Trustee and to
the Company.

          (d)  If at any time:

          (1) the Trustee shall fail to comply with Section 6.8 after written
request therefor by the Company or by any Holder who has been a bona fide Holder
of a Security for at least six months, or

          (2) the Trustee shall cease to be eligible under Section 6.9 and shall
fail to resign after written request therefor by the Company or by any such
Holder, or

                                     -53-

          (3) the Trustee shall become incapable of acting or shall be adjudged
a bankrupt or insolvent or a receiver of the Trustee or of its property shall be
appointed or any public officer shall take charge or control of the Trustee or
of its property or affairs for the purpose of rehabilitation, conservation or
liquidation,

then, in any such case, (i) the Company, acting pursuant to the authority of a
Board Resolution, may remove the Trustee with respect to all Securities, or (ii)
subject to Section 5.14, any Holder who has been a bona fide Holder of a
Security for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal
of the Trustee with respect to all Securities and the appointment of a successor
Trustee or Trustees.

          (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause with
respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee with respect to the
Securities of that or those series.  If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee
with respect to the Securities of any series shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities of such
series delivered to the Company and the retiring Trustee, the successor Trustee
so appointed shall, forthwith upon its acceptance of such appointment, become
the successor Trustee with respect to the Securities of such series and
supersede the successor Trustee appointed by the Company.  If no successor
Trustee with respect to the Securities of any series shall have been so
appointed by the Company or the Holders and accepted appointment in the manner
hereinafter provided, any Holder who has been a bona fide Holder of a Security
for at least six months may, subject to Section 5.14, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such
series.

          (f) The Company shall give notice of each resignation and each removal
of the Trustee with respect to the Securities of any series and each appointment
of a successor Trustee with respect to the Securities of any series by mailing
written notice of such event by first-class mail, postage prepaid, to the
Holders of Securities of such series as their names and addresses appear in the
Securities Register.  Each notice shall include the name of the successor
Trustee with respect to the Securities of such series and the address of its
Corporate Trust Office.

Section 6.11.  Acceptance of Appointment by Successor.

          (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the 

                                     -54-
<PAGE>
 
retiring Trustee shall become effective and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee; but, on the request of the
Company or the successor Trustee, such retiring Trustee shall, upon payment of
its charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder.

          (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts, and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates.

          (c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all rights, powers and trusts referred to
in paragraph (a) or (b) of this Section 6.11, as the case may be.

                                     -55-

          (d) No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article VI.

Section 6.12.  Merger, Conversion, Consolidation or Succession to Business.

          Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article VI, without the execution or filing of any paper or any further act on
the part of any of the parties hereto.  In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated, and in case any
Securities shall not have been authenticated, any successor to the Trustee may
authenticate such Securities either in the name of any predecessor Trustee or in
the name of such successor Trustee, and in all cases the certificate of
authentication shall have the full force which it is provided anywhere in the
Securities or in this Indenture that the certificate of the Trustee shall have.

Section 6.13.  Preferential Collection of Claims Against Company.

          If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

Section 6.14.  Appointment of Authenticating Agent.

          The Trustee may appoint an Authenticating Agent or Agents with respect
to one or more series of Securities which shall be authorized to act on behalf
of the Trustee to authenticate Securities of such series issued upon original
issue and upon exchange, registration of transfer or partial redemption thereof
or pursuant to Section 3.6, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder.  Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent.  Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, or of any State or Territory or
the District of Columbia, authorized under such laws to act 

                                     -56-
<PAGE>
 
as Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by Federal or State
authority. If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section 6.14 the combined
capital and surplus of such Authenticating Agent shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. If at any time an Authenticating Agent shall cease to be eligible
in accordance with the provisions of this Section 6.14, such Authenticating
Agent shall resign immediately in the manner and with the effect specified in
this Section 6.14.

          Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of an Authenticating Agent shall be the successor
Authenticating Agent hereunder, provided such corporation shall be otherwise
eligible under this Section, without the execution or filing of any paper or any
further act on the part of the Trustee or the Authenticating Agent.

          An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company.  Upon receiving such a notice
of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 6.14, the Trustee may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall give
notice of such appointment in the manner provided in Section 1.6 to all Holders
of Securities of the series with respect to which such Authenticating Agent will
serve.  Any successor Authenticating Agent upon acceptance of its appointment
hereunder shall become vested with all the rights, powers and duties of its
predecessor hereunder, with like effect as if originally named as an
Authenticating Agent.  No successor Authenticating Agent shall be appointed
unless eligible under the provision of this Section 6.14.

          The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section 6.14, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 6.7.

          If an appointment with respect to one or more series is made pursuant
to this Section 6.14, the Securities of such series may have endorsed thereon,
in addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

conveyance, transfer or lease the Company shall be discharged from all
obligations and covenants under the Indenture and the Securities and may be
dissolved and liquidated.

          Such successor Person may cause to be signed, and may issue either in
its own name or in the name of the Company, any or all of the Securities
issuable hereunder which theretofore shall not have been signed by the Company
and delivered to the Trustee; and, upon the order of such successor Person
instead of the Company and subject to all the terms, conditions and limitations
in this Indenture prescribed, the Trustee shall authenticate and shall deliver
any Securities which previously shall have been signed and delivered by the
officers of the Company to the Trustee for authentication pursuant to such
provisions and any Securities which such successor Person thereafter shall cause
to be signed and delivered to the Trustee on its behalf for the purpose pursuant
to such provisions.  All the Securities so issued shall in all respects have the
same legal rank and benefit under this Indenture as the Securities theretofore
or thereafter issued in accordance with the terms of this Indenture as though
all of such Securities had been issued at the date of the execution hereof.

          In case of any such consolidation, merger, sale, conveyance or lease,
such changes in phraseology and form may be made in the Securities thereafter to
be issued as may be appropriate.

          (5)  to add any additional Events of Default for the benefit of the
Holders of all or any series of Securities (and if such additional Events of

series in any material respect or, in the case of the Securities of a series
issued to a GBB Trust and for so long as any of the corresponding series of
Preferred Securities issued by such GBB Trust shall remain outstanding, the
holders of such Preferred Securities; or

          (8) to evidence and provide for the acceptance of appointment
hereunder by a successor Trustee with respect to the Securities of one or more

          With the consent of the Holders of not less than a majority in
principal amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by a Board Resolution, and the Trustee may
enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders of Securities of such series under this Indenture; provided, however,
that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security affected thereby,

          (1) except to the extent permitted by Sections 3.11 or 3.14 or as
otherwise specified as contemplated by Section 2.1 or Section 3.1 with respect
to the deferral of the payment of interest on the Securities of any series or

the Stated Maturity of the principal of, or any installment of interest
(including any Additional Interest) on, any Security, or reduce the principal
amount thereof or the rate of interest thereon or reduce any premium payable
upon the redemption thereof, or reduce the amount of principal of a Discount

Maturity thereof pursuant to Section 5.2, or change the place of payment where,
or the coin or currency in which, any Security or interest thereon is payable,
or impair the right to institute suit for the enforcement of any such payment on
or after the Stated Maturity thereof (or, in the case of redemption, on or after
the Redemption Date), or

          (2) reduce the percentage in principal amount of the Outstanding
Securities of any series, the consent of whose Holders is required for any such
supplemental indenture, or the consent of whose Holders is required for any
waiver (of compliance with certain provisions of this Indenture or certain

          (3) modify any of the provisions of this Section, Section 5.13 or

          (4) modify the provisions in Article XIII of this Indenture with
respect to the subordination of Outstanding Securities of any series in a manner
adverse to the Holders thereof;

                                     -63-
<PAGE>
 
provided, further, that, in the case of the Securities of a series issued to a
GBB Trust, so long as any of the corresponding series of Preferred Securities
issued by such GBB Trust remains outstanding, (i) no such amendment shall be
made that adversely affects the holders of such Preferred Securities in any
material respect, and no termination of this Indenture shall occur, and no
waiver of any Event of Default or compliance with any covenant under this
Indenture shall be effective, without the prior consent of the holders of at
least a majority of the aggregate liquidation preference of such Preferred
Securities then outstanding unless and until the principal (and premium, if any)
of the Securities of such series and all accrued and, subject to Section 3.7,
unpaid interest (including any Additional Interest) thereon have been paid in
full and (ii) no amendment shall be made to Section 5.8 of this Indenture that
would impair the rights of the holders of Preferred Securities provided therein
without the prior consent of the holders of each Preferred Security then
outstanding unless and until the principal (and premium, if any) of the
Securities of such series and all accrued and (subject to Section 3.7) unpaid
interest (including any Additional Interest) thereon have been paid in full.

          A supplemental indenture that changes or eliminates any covenant or
other provision of this Indenture that has expressly been included solely for
the benefit of one or more particular series of Securities or Preferred
Securities, or which modifies the rights of the Holders of Securities or holders
of Preferred Securities of such series with respect to such covenant or other
provision, shall be deemed not to affect the rights under this Indenture of the
Holders of Securities or holders of Preferred Securities of any other series.

          It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

Section 9.3.  Execution of Supplemental Indentures.

          In executing or accepting the additional series of Securities created
by any supplemental indenture permitted by this Article or the modifications
thereby of any series of Securities previously created by this Indenture, the

fully protected in relying upon, an Officers' Certificate and an Opinion of
Counsel stating that the execution of such supplemental indenture is authorized
or permitted by this Indenture, and that all conditions precedent have been
complied with.  The Trustee may, but shall not be obligated to, enter into any
such supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

Section 9.4.  Effect of Supplemental Indentures.

          Upon the execution of any supplemental indenture under this Article IX
or delivery to the Trustee of the Officers' Certificate pursuant to Section 3.1
hereof (which Officers' Certificate shall have the effect of a supplemental
indenture for all purposes hereunder), this Indenture shall be modified in
accordance therewith, and such supplemental indenture shall form a part of this
Indenture for all purposes; and every Holder of Securities theretofore or
thereafter authenticated and delivered hereunder shall be bound thereby.

Section 9.5.  Conformity with Trust Indenture Act.

          Every supplemental indenture executed pursuant to this Article IX and
every Officers' Certificate delivered to the trustee pursuant to Section 3.1
hereof shall conform to the requirements of the Trust Indenture Act as then in
effect.

Section 9.6.  Reference in Securities to Supplemental Indentures.

          Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article IX or delivery to the Trustee of
the Officers' Certificate pursuant to Section 3.1 hereof (which Officers'
Certificate shall have the effect of a supplemental indenture for all purposes
hereunder) may, and shall if required by the Company, bear a notation in form
approved by the Company as to any matter provided for in such supplemental
indenture or such Officers' Certificate.  If the Company shall so determine, new
Securities of any series so modified as to conform, in the opinion of the
Company, to any such supplemental indenture or such Officers's Certificate may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series.

                                   ARTICLE X

                                   COVENANTS

Section 10.1.  Payment of Principal, Premium and Interest.

          The Company covenants and agrees for the benefit of each series of
securities that it will duly and punctually pay the principal of (and premium,
if any) and interest on the Securities of that series in accordance with the
terms of such Securities and this Indenture.

                                     -65-
<PAGE>
 
Section 10.2.  Maintenance of Office or Agency.

          The Company will maintain in each Place of Payment for any series of
Securities, an office or agency where Securities of that series may be presented
or surrendered for payment and an office or agency where Securities of that
series may be surrendered for transfer or exchange and where notices and demands
to or upon the Company in respect of the Securities of that series and this
Indenture may be served.  The Company initially appoints the Trustee, acting
through its Corporate Trust Office, as its agent for said purposes.  The Company
will give prompt written notice to the Trustee of any change in the location of
any such office or agency.  If at any time the Company shall fail to maintain
such office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

          The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all of such purposes, and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in each
Place of Payment for Securities of any series for such purposes.  The Company
will give prompt written notice to the Trustee of any such designation and any
change in the location of any such office or agency.

Section 10.3.  Money for Security Payments to be Held in Trust.

          If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest on any of the Securities of such
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and premium, if any) or interest
so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided, and will promptly notify the Trustee of its
failure so to act.

          Whenever the Company shall have one or more Paying Agents, it will,
prior to 10:00 a.m. [______ CITY] time on each due date of the principal of or
interest on any Securities, deposit with a Paying Agent a sum sufficient to pay
the principal (and premium, if any) or interest so becoming due, such sum to be
held in trust for the benefit of the Persons entitled to such principal and
premium (if any) or interest, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its failure so to act.

                                     -66-
<PAGE>
 
          The Company will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section 10.3,
that such Paying Agent will:

          (1) hold all sums held by it for the payment of the principal of (and
premium, if any) or interest on Securities in trust for the benefit of the
Persons entitled thereto until such sums shall be paid to such Persons or
otherwise disposed of as herein provided;

          (2) give the Trustee notice of any default by the Company (or any
other obligor upon the Securities) in the making of any payment of principal
(and premium, if any) or interest:

          (3) at any time during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent; and

          (4) comply with the provisions of the Trust Indenture Act applicable
to it as a Paying Agent.

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (and premium, if
any) or interest on any Security and remaining unclaimed for two years after
such principal (and premium, if any) or interest has become due and payable
shall (unless otherwise required by mandatory provision of applicable escheat or
abandoned or unclaimed property law) be paid on Company Request to the Company,
or (if then held by the Company) shall (unless otherwise required by mandatory
provision of applicable escheat or abandoned or unclaimed property law) be
discharged from such trust; and the Holder of such Security shall thereafter, as
an unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in a newspaper published in the English language, customarily
published on each Business Day and 

                                     -67-
<PAGE>
 
of general circulation in the [BOROUGH OF ________, THE CITY OF __________],
notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication,
any unclaimed balance of such money then remaining will be repaid to the
Company.

Section 10.4.  Statement as to Compliance.

          The Company shall deliver to the Trustee, within 120 days after the
end of each calendar year of the Company ending after the date hereof, an
Officers' Certificate covering the preceding calendar year, stating whether or
not to the best knowledge of the signers thereof the Company is in default in
the performance, observance or fulfillment of or compliance with any of the
terms, provisions, covenants and conditions of this Indenture, and if the
Company shall be in default, specifying all such defaults and the nature and
status thereof of which they may have knowledge.  For the purpose of this
Section 10.4, compliance shall be determined without regard to any grace period
or requirement of notice provided pursuant to the terms of this Indenture.

Section 10.5.  Waiver of Certain Covenants.

          The Company may omit in any particular instance to comply with any
covenant or condition provided pursuant to Sections 3.1, 9.1(3), or 9.1(4) with
respect to the Securities of any series, if before or after the time for such
compliance the Holders of at least a majority in principal amount of the
Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
covenant or condition, but no such waiver shall extend to or affect such
covenant or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Company in respect of any
such covenant or condition shall remain in full force and effect.

Section 10.6.  Additional Sums.

          In the case of the Securities of a series issued to a GBB Trust, so
long as no Event of Default has occurred and is continuing and except as
otherwise specified as contemplated by Section 2.1 or Section 3.1, in the event
that (i) such GBB Trust is the Holder of all of the Outstanding Securities of
such series, (ii) a Tax Event in respect of such GBB Trust shall have occurred
and be continuing and (iii) the Company shall not have (A) redeemed the
Securities of such series pursuant to Section 11.7(b) or (B) terminated such GBB
Trust pursuant to Section 9.2(b) of the related Trust Agreement, the Company
shall pay to such GBB Trust (and its permitted successors or assigns under the
related Trust Agreement) for so long as such GBB Trust (or its permitted
successor or assignee) is the registered holder of any Securities of such
series, such additional amounts as may be necessary in order that the amount of

                                     -68-
<PAGE>
 
Distributions (including any Additional Amounts (as defined in such Trust
Agreement)) then due and payable by such GBB Trust on the related Preferred
Securities and Common Securities that at any time remain outstanding in
accordance with the terms thereof shall not be reduced as a result of any
Additional Taxes (the "Additional Sums"). Whenever in this Indenture or the
Securities there is a reference in any context to the payment of principal of or
interest on the Securities, such mention shall be deemed to include mention of
the payments of the Additional Sums provided for in this paragraph to the extent
that, in such context, Additional Sums are, were or would be payable in respect
thereof pursuant to the provisions of this paragraph and express mention of the
payment of Additional Sums (if applicable) in any provisions hereof shall not be
construed as excluding Additional Sums in those provisions hereof where such
express mention is not made; provided, however, that the deferral of the payment
of interest pursuant to Section 3.11 or the Securities shall not defer the
payment of any Additional Sums that may be due and payable.

Section 10.7.  Additional Covenants.

          The Company covenants and agrees with each Holder of Securities of any
series that it shall not, and it shall not permit any Subsidiary of the Company
to, (a) declare or pay any dividends or distributions on, or redeem purchase,
acquire or make a liquidation payment with respect to, any shares of the
Company's capital stock (which includes common and preferred stock), or (b) make
any payment of principal of or interest or premium, if any, on or repay,
repurchase or redeem any debt securities of the Company (including Securities
other than the Securities of such series) that rank pari passu in all respects
with or junior in interest to the Securities of such series or make any
guarantee payments with respect to any guarantee by the Company of debt
securities of any subsidiary of the Company if such guarantee ranks pari passu
in all respects with or junior in interest to the Securities (other than (a)
dividends or distributions in capital stock of the Company (which includes
common and preferred stock), (b) any declaration of a dividend in connection
with the implementation of a rights plan or the redemption or repurchase of any
such rights pursuant thereto, (c) payments under the GBB Guarantee related to
the Preferred Securities issued by the GBB Trust holding Securities of such
series, and (d) purchases of Common Stock related to the issuance of Common
Stock or rights under any of the Company's benefit plans for its directors,
officers or employees or related to the issuance of Common Stock (or securities
convertible into or exchangeable for common stock) as consideration in an
acquisition transaction) if at such time (i) there shall have occurred any event
of which the Company has actual knowledge that (A) with the giving of notice or
the lapse of time or both, would constitute an Event of Default with respect to
the Securities of such series and (B) in respect of which the Company shall not
have taken reasonable steps to cure, (ii) if the Securities of such series are
held by a GBB Trust, the Company shall be in default with respect to its payment
of any obligations 

                                     -69-
<PAGE>
 
under the GBB Guarantee relating to the Preferred Securities issued by such GBB
Trust or (iii) the Company shall have given notice of its election to begin an
Extension Period with respect to the Securities of such series as provided
herein and shall not have rescinded such notice, or such Extension Period, or
any extension thereof, shall be continuing.

          The Company also covenants with each Holder of Securities of a series
issued to a GBB Trust (i) to maintain directly or indirectly 100% ownership of
the Common Securities of such GBB Trust; provided, however, that any permitted
successor of the Company hereunder may succeed to the Company's ownership of
such Common Securities, (ii) not to voluntarily terminate, wind-up or liquidate
such GBB Trust, except (a) in connection with a distribution of the Securities
of such series to the holders of Trust Securities in liquidation of such GBB
Trust or (b) in connection with certain mergers, consolidations or amalgamations
permitted by the related Trust Agreement and (iii) to use its reasonable
efforts, consistent with the terms and provisions of such Trust Agreement, to
cause such GBB Trust to remain classified as a grantor trust and not an
association taxable as a corporation for United States federal income tax
purposes.

                                  ARTICLE XI

                           REDEMPTION OF SECURITIES

Section 11.1  Applicability of This Article.

          Redemption of Securities of any series (whether by operation of a
sinking fund or otherwise) as permitted or required by any form of Security
issued pursuant to this Indenture shall be made in accordance with such form of
Security and this Article; provided, however, that if any provision of any such
form of Security shall conflict with any provision of this Article, the
provision of such form of Security shall govern.  Except as otherwise set forth
in the form of Security for such series, each Security of such series shall be
subject to partial redemption only in the amount of $25 or, in the case of the
Securities of a series issued to a GBB Trust, $25, or integral multiples of $25
in excess thereof.

Section 11.2.  Election to Redeem; Notice to Trustee.

          The election of the Company to redeem any Securities shall be
evidenced by or pursuant to a Board Resolution.  In case of any redemption at
the election of the Company of less than all of the Securities of any particular
series and having the same terms, the Company shall, not less than 30 nor more
than 60 days prior to the Redemption Date (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such date and of the
principal amount of Securities of that series to be redeemed.  In the case of
any redemption of Securities prior to the expiration of any 

                                     -70-
<PAGE>
 
restriction on such redemption provided in the terms of such Securities, the
Company shall furnish the Trustee with an Officers' Certificate and an Opinion
of Counsel evidencing compliance with such restriction.

Section 11.3.  Selection of Securities to be Redeemed.

          If less than all the Securities of any series are to be redeemed
(unless all the Securities of such series and of a specified tenor are to be
redeemed or unless such redemption affects only a single Security), the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of a portion of the principal amount of any Security of such series,
provided that the portion of the principal amount of any Security not redeemed
shall be in an authorized denomination (which shall not be less than the minimum
authorized denomination) for such Security.  If less than all the Securities of
such series and of a specified tenor are to be redeemed (unless such redemption
affects only a single Security), the particular Securities to be redeemed shall
be selected not more than 60 days prior to the Redemption Date by the Trustee,
from the Outstanding Securities of such series and specified tenor not
previously called for redemption in accordance with the preceding sentence.

          The Trustee shall promptly notify the Company in writing of the
Securities selected for partial redemption and the principal amount thereof to
be redeemed.  For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed.  If the Company shall so direct, Securities registered in the name of
the Company, any Affiliate or any Subsidiary thereof shall not be included in
the Securities selected for redemption.

Section 11.4.  Notice of Redemption.

          Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not later than the thirtieth day, and not earlier than the
sixtieth day, prior to the Redemption Date, to each Holder of Securities to be
redeemed, at the address of such Holder as it appears in the Securities
Register.

          With respect to Securities of each series to be redeemed, each notice
of redemption shall state:

          (a)  the Redemption Date;

          (b)  the Redemption Price;

                                     -71-
<PAGE>
 
          (c) if less than all Outstanding Securities of such particular series
and having the same terms are to be redeemed, the identification (and, in the
case of partial redemption, the respective principal amounts) of the particular
Securities to be redeemed;

          (d) that on the Redemption Date, the Redemption Price will become due
and payable upon each such Security or portion thereof, and that interest
thereon, if any, shall cease to accrue on and after said date;

          (e) the place or places where such Securities are to be surrendered
for payment of the Redemption Price; and

          (f) that the redemption is for a sinking fund, if such is the case.

          Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall not be
irrevocable.  The notice if mailed in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the Holder
receives such notice.  In any case, a failure to give such notice by mail or any
defect in the notice to the Holder of any Security designated for redemption as
a whole or in part shall not affect the validity of the proceedings for the
redemption of any other Security.

Section 11.5.  Deposit of Redemption Price.

          Prior to 10:00 a.m. [______ CITY] time on the Redemption Date
specified in the notice of redemption given as provided in Section 11.4, the

the Company is acting as its own Paying Agent, the Company will segregate and
hold in trust as provided in Section 10.3) an amount of money sufficient to pay
the Redemption Price of, and any accrued interest (including Additional
Interest) on, all the Securities which are to be redeemed on that date.

Section 11.6.  Payment of Securities Called for Redemption.

otherwise specified as contemplated by Section 3.1, installments of interest
whose Stated Maturity is on or prior to the Redemption Date will be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates

thereof, at the expense of the Company, a new Security or Securities of the same
series, of authorized denominations, in aggregate principal amount equal to the
portion of the Security not redeemed so presented and having the same Original
Issue Date, Stated Maturity and terms.  If a Global Security is so surrendered,
such new Security will also be a new Global Security.

          If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal of and premium, if any, on such
Security shall, until paid, bear interest from the Redemption Date at the rate
prescribed therefor in the Security.

Section 11.7.  Right of Redemption of Securities Initially Issued to a GBB
               Trust.

          In the case of the Securities of a series initially issued to a GBB

Company, at its option, may redeem such Securities (i) on or after the date five
years after the Original Issue Date of such Securities, in whole at any time or
in part from time to time, or (ii) upon the occurrence and during the
continuation of a Tax Event, Investment Company Event, or Capital Treatment
Event, at any time within 90udays following the occurrence of such Tax Event,
Investment Company Event or Capital Treatment Event in respect of such GBB
Trust, in whole (but not in part), in each case at a Redemption Price equal to
100% of the principal amount thereof.

                                  ARTICLE XII

                                 SINKING FUNDS

Section 12.1.  Applicability of Article.

          The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 3.1 for such Securities.

          The minimum amount of any sinking fund payment provided for by the
terms of any Securities of any series is herein referred to as a "mandatory
sinking fund payment", and any sinking fund payment in excess of such minimum
amount 

                                     -73-
<PAGE>
 
which is permitted to be made by the terms of such Securities of any series is
herein referred to as an "optional sinking fund payment". If provided for by the
terms of any Securities of any series, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 12.2. Each sinking
fund payment shall be applied to the redemption of Securities of any series as
provided for by the terms of such Securities.

Section 12.2.  Satisfaction of Sinking Fund Payments with Securities.

          In lieu of making all or any part of a mandatory sinking fund payment
with respect to any Securities of a series in cash, the Company may at its
option, at any time no more than 16 months and no less than 30 days prior to the
date on which such sinking fund payment is due, deliver to the Trustee
Securities of such series (together with the unmatured coupons, if any,
appertaining thereto) theretofore purchased or otherwise acquired by the
Company, except Securities of such series that have been redeemed through the
application of mandatory or optional sinking fund payments pursuant to the terms
of the Securities of such series, accompanied by a Company Order instructing the
Trustee to credit such obligations and stating that the Securities of such
series were originally issued by the Company by way of bona fide sale or other
negotiation for value; provided that the Securities to be so credited have not
been previously so credited.  The Securities to be so credited shall be received
and credited for such purpose by the Trustee at the redemption price for such
Securities, as specified in the Securities so to be redeemed, for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly.

Section 12.3.  Redemption of Securities for Sinking Fund.

          Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
such Securities pursuant to the terms of such Securities, the portion thereof,
if any, which is to be satisfied by payment of cash in the currency in which the
Securities of such series are payable (except as provided pursuant to Section
3.1) and the portion thereof, if any, which is to be satisfied by delivering and
crediting Securities pursuant to Section 12.2 and will also deliver to the
Trustee any Securities to be so delivered.  Such Officers' Certificate shall be
irrevocable and upon its delivery the Company shall be obligated to make the
cash payment or payments therein referred to, if any, on or before the
succeeding sinking fund payment date.  In the case of the failure of the Company
to deliver such Officers' Certificate (or, as required by this Indenture, the
Securities and coupons, if any, specified in such Officers' Certificate), the
sinking fund payment due on the succeeding sinking fund payment date for such
series shall be paid entirely in cash and shall be sufficient to redeem the
principal amount of the Securities of such series subject to a mandatory sinking
fund payment without the right to deliver or 

                                     -74-
<PAGE>
 
credit securities as provided in Section 12.2 and without the right to make the
optional sinking fund payment with respect to such series at such time.

          Any sinking fund payment or payments (mandatory or optional) made in
cash plus any unused balance of any preceding sinking fund payments made with
respect to the Securities of any particular series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent) on
the sinking fund payment date on which such payment is made (or, if such payment
is made before a sinking fund payment date, on the sinking fund payment date
immediately following the date of such payment) to the redemption of Securities
of such series at the Redemption Price specified in such Securities with respect
to the sinking fund.  Any sinking fund moneys not so applied or allocated by the
Trustee (or, if the Company is acting as its own Paying Agent, segregated and
held in trust by the Company as provided in Section 10.3) for such series and
together with such payment (or such amount so segregated) shall be applied in
accordance with the provisions of this Section 12.3.  Any and all sinking fund
moneys with respect to the Securities of any particular series held by the
Trustee (or if the Company is acting as its own Paying Agent, segregated and
held in trust as provided in Section 10.3) on the last sinking fund payment date
with respect to Securities of such series and not held for the payment or
redemption of particular Securities of such series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent),
together with other moneys, if necessary, to be deposited (or segregated)
sufficient for the purpose, to the payment of the principal of the Securities of
such series at Maturity.  The Trustee shall select the Securities to be redeemed
upon such sinking fund payment date in the manner specified in Section 11.3 and
cause notice of the redemption thereof to be given in the name of and at the
expense of the Company in the manner provided in Section 11.4.  Such notice
having been duly given, the redemption of such Securities shall be made upon the
terms and in the manner stated in Section 11.6.  On or before each sinking fund
payment date, the Company shall pay to the Trustee (or, if the Company is acting
as its own Paying Agent, the Company shall segregate and hold in trust as
provided in Section 10.3) in cash a sum in the currency in which Securities of
such series are payable (except as provided pursuant to Section 3.1) equal to
the principal and any interest accrued to the Redemption Date for Securities or
portions thereof to be redeemed on such sinking fund payment date pursuant to
this Section 12.3.

          Neither the Trustee nor the Company shall redeem any Securities of a
series with sinking fund moneys or mail any notice of redemption of Securities
of such series by operation of the sinking fund for such series during the
continuance of a default in payment of interest, if any, on any Securities of
such series or of any Event of Default (other than an Event of Default occurring
as a consequence of this paragraph) with respect to the Securities of such
series, except that if the notice of redemption shall have been provided in
accordance with the provisions hereof, the Trustee (or the Company, if the
Company is then acting as its own Paying Agent) 

                                     -75-
<PAGE>
 
shall redeem such Securities if cash sufficient for that purpose shall be
deposited with the Trustee (or segregated by the Company) for that purpose in
accordance with the terms of this Article XII. Except as aforesaid, any moneys
in the sinking fund for such series at the time when any such default or Event
of Default shall occur and any moneys thereafter paid into such sinking fund
shall, during the continuance of such default or Event of Default, be held as
security for the payment of the Securities and coupons, if any, of such series;
provided, however, that in case such default or Event of Default shall have been
cured or waived herein, such moneys shall thereafter be applied on the next
sinking fund payment date for the Securities of such series on which such moneys
may be applied pursuant to the provisions of this Section 12.3.

                                  ARTICLE XIII

                          SUBORDINATION OF SECURITIES

Section 13.1.  Securities Subordinate to Senior and Subordinated Debt.

          The Company covenants and agrees, and each Holder of a Security, by
its acceptance thereof, likewise covenants and agrees, that, to the extent and
in the manner hereinafter set forth in this Article XIII, the payment of the
principal of (and premium, if any) and interest (including any Additional
Interest) on each and all of the Securities are hereby expressly made
subordinate and subject in right of payment to the prior payment in full of all
amounts then due and payable in respect of all Senior and Subordinated Debt.

Section 13.2.  Payment Over of Proceeds Upon Dissolution, Etc.

          In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company (each such event, if any, herein
sometimes referred to as a "Proceeding"), then the holders of Senior and
Subordinated Debt shall be entitled to receive payment in full of Allocable
Amounts of such Senior and Subordinated Debt, or provision shall be made for
such payment in cash or cash equivalents or otherwise in a manner satisfactory
to the holders of Senior and Subordinated Debt, before the Holders of the
Securities are entitled to receive or retain any payment or distribution of any
kind or character, whether in cash, property or securities (including any
payment or distribution which may be payable or deliverable by reason of the
payment of any other Debt of the Company subordinated to the payment of the
Securities, such payment or distribution being hereinafter referred to as a
"Junior Subordinated Payment"), on account of principal of (or premium, if any)
or interest (including any Additional Interest) on the Securities or on account
of the purchase or other acquisition of Securities by the Company or any
Subsidiary and to that end the holders of Senior and Subordinated 

                                     -76-
<PAGE>
 
Debt shall be entitled to receive, for application to the payment thereof, any
payment or distribution of any kind or character, whether in cash, property or
securities, including any Junior Subordinated Payment, which may be payable or
deliverable in respect of the Securities in any such Proceeding.

          In the event that, notwithstanding the foregoing provisions of this
Section 13.2, the Trustee or the Holder of any Security shall have received any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, including any Junior Subordinated
Payment, before all Allocable Amounts of all Senior and Subordinated Debt are
paid in full or payment thereof is provided for in cash or cash equivalents or
otherwise in a manner satisfactory to the holders of Senior and Subordinated
Debt, and if such fact shall, at or prior to the time of such payment or
distribution, have been made known to the Trustee or, as the case may be, such
Holder, then and in such event such payment or distribution shall be paid over
or delivered forthwith to the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee, agent or other Person making payment or
distribution of assets of the Company for application to the payment of all
Allocable Amounts of all Senior and Subordinated Debt remaining unpaid, to the
extent necessary to pay all Allocable Amounts of all Senior and Subordinated
Debt in full, after giving effect to any concurrent payment or distribution to
or for the holders of Senior and Subordinated Debt.

          For purposes of this Article XIII only, the words "any payment or
distribution of any kind or character, whether in cash, property or securities"
shall not be deemed to include shares of stock of the Company as reorganized or
readjusted, or securities of the Company or any other corporation provided for
by a plan of reorganization or readjustment which securities are subordinated in
right of payment to all then outstanding Senior and Subordinated Debt to
substantially the same extent as the Securities are so subordinated as provided
in this Article XIII.  The consolidation of the Company with, or the merger of
the Company into, another Person or the liquidation or dissolution of the
Company following the sale of all or substantially all of its properties and
assets as an entirety to another Person upon the terms and conditions set forth
in Article VIII shall not be deemed a Proceeding for the purposes of this
Section 13.2 if the Person formed by such consolidation or into which the
Company is merged or the Person which acquires by sale such properties and
assets as an entirety, as the case may be, shall, as a part of such
consolidation, merger, or sale comply with the conditions set forth in Article
VIII.

Section 13.3.  Prior Payment to Senior and Subordinated Debt Upon Acceleration
               of Securities.

          In the event that any Securities are declared due and payable before
their Stated Maturity, then and in such event the holders of the Senior and
Subordinated 

                                     -77-
<PAGE>
 
Debt outstanding at the time such Securities so become due and payable shall be
entitled to receive payment in full of all Allocable Amounts due on or in
respect of such Senior and Subordinated Debt (including any amounts due upon
acceleration), or provision shall be made for such payment in cash or cash
equivalents or otherwise in a manner satisfactory to the holders of Senior and
Subordinated Debt, before the Holders of the Securities are entitled to receive
any payment or distribution of any kind or character, whether in cash,
properties or securities (including any Junior Subordinated Payment) by the
Company on account of the principal of (or premium, if any) or interest
(including any Additional Interest) on the Securities or on account of the
purchase or other acquisition of Securities by the Company or any Subsidiary;
provided, however, that nothing in this Section 13.3 shall prevent the
satisfaction of any sinking fund payment in accordance with this Indenture or as
otherwise specified as contemplated by Section 3.1 for the Securities of any
series by delivering and crediting pursuant to Section 12.2 or as otherwise
specified as contemplated by Section 3.1 for the Securities of any series
Securities which have been acquired (upon redemption or otherwise) prior to such
declaration of acceleration.

          In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section 13.3, and if such fact shall, at or prior
to the time of such payment, have been made known to the Trustee or, as the case
may be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company.

          The provisions of this Section 13.3 shall not apply to any payment
with respect to which Section 13.2 would be applicable.

Section 13.4.  No Payment When Senior and Subordinated Debt in Default.

          (a) In the event and during the continuation of any default in the
payment of principal of (or premium, if any) or interest on any Senior and
Subordinated Debt, or in the event that any event of default with respect to any
Senior and Subordinated Debt shall have occurred and be continuing and shall
have resulted in such Senior and Subordinated Debt becoming or being declared
due and payable prior to the date on which it would otherwise have become due
and payable, unless and until such event of default shall have been cured or
waived or shall have ceased to exist and such acceleration shall have been
rescinded or annulled, or (b) in the event any judicial proceeding shall be
pending with respect to any such default in payment or such event or default,
then no payment or distribution of any kind or character, whether in cash,
properties or securities (including any Junior Subordinated Payment) shall be
made by the Company on account of principal of (or premium, if any) or interest
(including any Additional Interest), if any, on the Securities or on account of
the purchase or other acquisition of Securities by the 

                                     -78-
<PAGE>
 
Company or any Subsidiary, in each case unless and until all Allocable Amounts
of such Senior and Subordinated Debt are paid in full; provided, however, that
nothing in this Section 13.4 shall prevent the satisfaction of any sinking fund
payment in accordance with this Indenture or as otherwise specified as
contemplated by Section 3.1 for the Securities of any series by delivering and
crediting pursuant to Section 12.2 or as otherwise specified as contemplated by
Section 3.1 for the Securities of any series Securities which have been acquired
(upon redemption or otherwise) prior to such default in payment or event of
default.

          In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section 13.4, and if such fact shall, at or prior
to the time of such payment, have been made known to the Trustee or, as the case
may be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company.

          The provisions of this Section 13.4 shall not apply to any payment
with respect to which Section 13.2 would be applicable.

Section 13.5.  Payment Permitted If No Default.

          Nothing contained in this Article XIII or elsewhere in this Indenture
or in any of the Securities shall prevent (a) the Company, at any time except
during the pendency of any Proceeding referred to in Section 13.2 or under the
conditions described in Sections 13.3 and 13.4, from making payments at any time
of principal of (and premium, if any) or interest (including Additional
Interest) on the Securities, or (b) the application by the Trustee of any money
deposited with it hereunder to the payment of or on account of the principal of
(and premium, if any) or interest (including any Additional Interest) on the
Securities or the retention of such payment by the Holders, if, at the time of
such application by the Trustee, it did not have knowledge that such payment
would have been prohibited by the provisions of this Article XIII.

Section 13.6.  Subrogation to Rights of Holders of Senior and Subordinated Debt.

          Subject to the payment in full of all amounts due or to become due on
all Senior and Subordinated Debt, or the provision for such payment in cash or
cash equivalents or otherwise in a manner satisfactory to the holders of Senior
and Subordinated Debt, the Holders of the Securities shall be subrogated to the
extent of the payments or distributions made to the holders of such Senior and
Subordinated Debt pursuant to the provisions of this Article XIII (equally and
ratably with the holders of all indebtedness of the Company which by its express
terms is subordinated to Senior and Subordinated Debt of the Company to
substantially the

                                     -79-
<PAGE>
 
same extent as the Securities are subordinated to the Senior and Subordinated
Debt and is entitled to like rights of subrogation by reason of any payments or
distributions made to holders of such Senior and Subordinated Debt) to the
rights of the holders of such Senior and Subordinated Debt to receive payments
and distributions of cash, property and securities applicable to the Senior and
Subordinated Debt until the principal of (and premium, if any) and interest on
the Securities shall be paid in full. For purposes of such subrogation, no
payments or distributions to the holders of the Senior and Subordinated Debt of
any cash, property or securities to which the Holders of the Securities or the
Trustee would be entitled except for the provisions of this Article, and no
payments over pursuant to the provisions of this Article XIII to the holders of
Senior and Subordinated Debt by Holders of the Securities or the Trustee, shall,
as among the Company, its creditors other than holders of Senior and
Subordinated Debt, and the Holders of the Securities, be deemed to be a payment
or distribution by the Company to or on account of the Senior and Subordinated
Debt.

Section 13.7.  Provisions Solely to Define Relative Rights.

          The provisions of this Article XIII are and are intended solely for
the purpose of defining the relative rights of the Holders of the Securities on
the one hand and the holders of Senior and Subordinated Debt on the other hand.
Nothing contained in this Article XIII or elsewhere in this Indenture or in the
Securities is intended to or shall (a) impair, as between the Company and the
Holders of the Securities, the obligations of the Company, which are absolute
and unconditional, to pay to the Holders of the Securities the principal of (and
premium, if any) and interest (including any Additional Interest) on the
Securities as and when the same shall become due and payable in accordance with
their terms; or (b) affect the relative rights against the Company of the
Holders of the Securities and creditors of the Company other than their rights
in relation to the holders of Senior and Subordinated Debt; or (c) prevent the
Trustee or the Holder of any Security from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture including, without
limitation, filing and voting claims in any Proceeding, subject to the rights,
if any, under this Article XIII of the holders of Senior and Subordinated Debt
to receive cash, property and securities otherwise payable or deliverable to the
Trustee or such Holder.

Section 13.8.  Trustee to Effectuate Subordination.

          Each Holder of a Security by his or her acceptance thereof authorizes
and directs the Trustee on his or her behalf to take such action as may be
necessary or appropriate to acknowledge or effectuate the subordination provided
in this Article XIII and appoints the Trustee his or her attorney-in-fact for
any and all such purposes.

                                     -80-
<PAGE>
 
Section 13.9.  No Waiver of Subordination Provisions.

          No right of any present or future holder of any Senior and
Subordinated Debt to enforce subordination as herein provided shall at any time
in any way be prejudiced or impaired by any act or failure to act on the part of
the Company or by any act or failure to act, in good faith, by any such holder,
or by any noncompliance by the Company with the terms, provisions and covenants
of this Indenture, regardless of any knowledge thereof that any such holder may
have or be otherwise charged with.

          Without in any way limiting the generality of the immediately
preceding paragraph, the holders of Senior and Subordinated Debt may, at any
time and from to time, without the consent of or notice to the Trustee or the
Holders of the Securities, without incurring responsibility to the Holders of
the Securities and without impairing or releasing the subordination provided in
this Article or the obligations hereunder of the Holders of the Securities to
the holders of Senior and Subordinated Debt, do any one or more of the
following:  (i) change the manner, place or terms of payment or extend the time
of payment of, or renew or alter, Senior and Subordinated Debt, or otherwise
amend or supplement in any manner Senior and Subordinated Debt or any instrument
evidencing the same or any agreement under which Senior and Subordinated Debt is
outstanding; (ii) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing Senior and Subordinated Debt;
(iii) release any Person liable in any manner for the collection of Senior and
Subordinated Debt; and (iv) exercise or refrain from exercising any rights
against the Company and any other Person.

Section 13.10. Notice to Trustee.

          The Company shall give prompt written notice to the Trustee of any
fact known to the Company which would prohibit the making of any payment to or
by the Trustee in respect of the Securities.  Notwithstanding the provisions of
this Article XIII or any other provision of this Indenture, the Trustee shall
not be charged with knowledge of the existence of any facts which would prohibit
the making of any payment to or by the Trustee in respect of the Securities,
unless and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior and Subordinated Debt or from any trustee, agent
or representative therefor; provided, however, that if the Trustee shall not
have received the notice provided for in this Section 13.10 at least two
Business Days prior to the date upon which by the terms hereof any monies may
become payable for any purpose (including, without limitation, the payment of
the principal of (and premium, if any) or interest (including any Additional
Interest) on any Security), then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive such
monies and to apply the same to the purpose for 

                                     -81-
<PAGE>
 
which they were received and shall not be affected by any notice to the contrary
which may be received by it within two Business Days prior to such date.

          Subject to the provisions of Section 6.1, the Trustee shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior and Subordinated Debt (or a
trustee therefor) to establish that such notice has been given by a holder of
Senior and Subordinated Debt (or a trustee therefor). In the event that the
Trustee determines in good faith that further evidence is required with respect
to the right of any Person as a holder of Senior and Subordinated Debt to
participate in any payment or distribution pursuant to this Article, the Trustee
may request such Person to furnish evidence to the reasonable satisfaction of
the Trustee as to the amount of Senior and Subordinated Debt held by such
Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
Person under this Article, and if such evidence is not furnished, the Trustee
may defer any payment to such Person pending judicial determination as to the
right of such Person to receive such payment.

Section 13.11. Reliance on Judicial Order or Certificate of Liquidating Agent.

          Upon any payment or distribution of assets of the Company referred to
in this Article XIII, the Trustee, subject to the provisions of Section 6.1, and
the Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such Proceeding is
pending, or a certificate of the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee for the benefit of creditors, agent or other Person
making such payment or distribution, delivered to the Trustee or to the Holders
of Securities, for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of the Senior and
Subordinated Debt and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article XIII.

Section 13.12. Trustee Not Fiduciary for Holders of Senior and Subordinated
Debt.

          The Trustee, in its capacity as trustee under this Indenture, shall
not be deemed to owe any fiduciary duty to the holders of Senior and
Subordinated Debt and shall not be liable to any such holders if it shall in
good faith mistakenly pay over or distribute to Holders of Securities or to the
Company or to any other Person cash, property or securities to which any holders
of Senior and Subordinated Debt shall be entitled by virtue of this Article or
otherwise.

Section 13.13. Rights of Trustee as Holder of Senior and Subordinated Debt;
               Preservation of Trustee's Rights.

          The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article XIII with respect to any Senior and
Subordinated Debt which may at any time be held by it, to the same extent as any
other holder of Senior and Subordinated Debt, and nothing in this Indenture
shall deprive the Trustee of any of its rights as such holder.

Section 13.14. Article Applicable to Paying Agents.

          In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article XIII shall in such case (unless the context otherwise
requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article XIII in addition to or in place of the Trustee.

Section 13.15. Certain Conversions or Exchanges Deemed Payment.

          For the purposes of this Article XIII only, (a) the issuance and
delivery of junior securities upon conversion or exchange of Securities shall
not be deemed to constitute a payment or distribution on account of the
principal of (or premium, if any) or interest (including any Additional
Interest) on Securities or on account of the purchase or other acquisition of
Securities, and (b) the payment, issuance or delivery of cash, property or
securities (other than junior securities) upon conversion or exchange of a
Security shall be deemed to constitute payment on account of the principal of
such security.  For the purposes of this Section 13.15, the term "junior
securities" means (i) shares of any stock of any class of the Company and (ii)
securities of the Company which are subordinated in right of payment to all
Senior and Subordinated Debt which may be outstanding at the time of issuance or
delivery of such securities to substantially the same extent as, or to a greater
extent than, the Securities are so subordinated as provided in this Article
XIII.

          This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

                    OFFICERS' CERTIFICATE AND COMPANY ORDER
                    ---------------------------------------


     Pursuant to the Indenture dated as of March _____, 1997 (the "Indenture"),
between Greater Bay Bancorp, a California corporation (the "Company") and
Wilmington Trust Company, as Debenture Trustee (the "Debenture Trustee") and
resolutions adopted by the Company's Board of Directors on ________________;
this Officers' Certificate is being delivered to the Debenture Trustee to
establish the terms of a series of Securities in accordance with Section 3.1 of
the Indenture, to establish the form of the Securities of such series in
accordance with Section 2.1 of the Indenture, to request the authentication and
delivery of the Securities of such series pursuant to Section 3.3 of the
Indenture and to comply with the provisions of Section 1.2 of the Indenture.
This Officers' Certificate shall be treated for all purposes under the Indenture
as a supplemental indenture thereto.

     All conditions precedent provided for in the Indenture relating to the
establishment of (i) a series of Securities and (ii) the form of Securities of
such series  have been complied with.

     Capitalized terms used herein and not otherwise defined herein shall have
the meanings assigned to them in the Indenture.

     A.   Establishment of a Series of Securities pursuant to Section 3.1 of the

Junior Subordinated Deferrable Interest Debentures Due _________________."

          (2) The aggregate principal amount of such series of Securities to be
issued pursuant to this Officers' Certificate and Company Order shall be limited
to $_______ (except for Securities authenticated and delivered upon registration
of, transfer of, or in exchange for, or in lieu of, other Securities of such
series pursuant to Sections 3.4, 3.5, 3.6, 9.6 or 11.7 of the Indenture and
except for any Securities which, pursuant to Section 3.3 of the Indenture, are
deemed never to have been authenticated and delivered thereunder).

                                      -1-
<PAGE>
 
          (3) The date on which the principal of the Securities is due and
payable shall be __________________.

          (4) The Securities shall bear interest at the rate of _________% per
annum (based upon a 360-day year of twelve 30-day months), from and including
___________ or from and including the most recent Interest Payment Date to which
interest has been paid or duly provided for, as the case may be, payable
quarterly in arrears on ________________, _________________,______________ and
_______________ in each year, commencing _____________, until the principal
thereof is paid or made available for payment.  Each such ______________,
_______________,_________________ or _________________ shall be an
"Interest Payment Date" for the Securities of such series, and the Business Day
next preceding an Interest Payment Date shall be the "Regular Record Date" for
the interest payable on such Interest Payment Date.  Accrued interest that is
not paid on such applicable Interest Payment Date will bear additional interest
on the amount thereof (to the extent permitted by law) at a rate per annum of
_________% thereof compounded quarterly.

     In addition, so long as no Event of Default with respect to the Securities
has occurred or is continuing, the Company has the right under the Indenture at
any time during the term of such Securities to defer the payment of interest at
any time or from time to time for a period not exceeding 20 consecutive
quarterly periods (each such period an "Extension Period"), provided that no
Extension Period may extend beyond the Stated Maturity.  At the end of such
Extension Period, the Company must pay all interest then accrued and unpaid
(together with interest thereon at the annual rate of ___________%, compounded
quarterly, to the extent permitted by applicable law).

          (5) Principal of (and premium, if any) and interest on the Securities
will be payable, and, except as provided in Section 3.5 of the Indenture with
respect to a Global Security (as defined below), the transfer of the Securities
will be registrable and Securities will be exchangeable for Securities bearing
identical terms and provisions at the corporate trust office of Wilmington Trust
Company, in the City of New York, New York.

          (6) The Securities will be redeemable in whole at any time and in part
from time to time, at the option of the Company at any time on or after
___________, subject to the Company having received prior approval of the Board
of Governors of the Federal Reserve System (the "Federal Reserve"), at a
redemption price equal to the accrued and unpaid interest on the Securities so
redeemed to the date fixed for redemption, plus 100% of the principal amount
thereof.

          In addition, upon the occurrence of a Capital Treatment Event, an
Investment Company Event or a Tax Event (as defined below) the Company may, at
its option and subject to receipt of prior approval of the Federal Reserve if
then required under applicable capital guidelines or policies of the Federal
Reserve, redeem the Securities in whole (but not in part) at any time within 90
days of the occurrence of such Capital Treatment Event,
   
                                   -2-

Investment Company Event or Tax Event, at a redemption price equal to the
accrued and unpaid interest on the Securities so redeemed to the date fixed for
redemption, plus 100% of the principal amount thereof.

     "Capital Treatment Event" means the reasonable determination by the Company
that, as a result of any amendment to, or change (including any prospective
change) in, the laws (or any regulations thereunder) of the United States or any
political subdivision thereof or therein, or as a result of any official or
administrative pronouncement or action or judicial decision interpreting or
applying such laws or regulations, which amendment or change is effective or
such prospective change, pronouncement or decision is announced on or after the
date of issuance of the ________ % Cumulative Trust Preferred Securities
(Liquidation Amount $25 per Trust Preferred Security) (the "Preferred
Securities") of GBB Capital I, a statutory business trust formed under the laws
of the State of Delaware ("GBB Capital"), there is more than an insubstantial
risk of impairment of the Company's ability to treat the Preferred Securities
(or any substantial portion thereof) as "Tier I Capital" (or the then equivalent
thereof) for purposes of the capital adequacy guidelines of the Federal Reserve,
as then in effect and applicable to the Company.

     "Investment Company Event" "means the receipt by the Company and GBB
Capital of an opinion of counsel, rendered by a law firm experienced in such
matters, to the effect that, as a result of any change in law or regulation or a
change in interpretation or application of law or regulation by any legislative
body, court, governmental agency or regulatory authority, GBB Capital is or will
be considered an "investment company" that is required to be registered under
the Investment Company Act of 1940, as amended, which change becomes effective
on or after the date of original issuance of the Preferred Securities of GBB
Capital.

     "Tax Event"  means the receipt by the Company and GBB Capital of an opinion
of counsel experienced in such matters to the effect that, as a result of any
amendment to, or change (including any announced prospective change) in, the
laws (or any regulations thereunder) of the United States or any political
subdivision or taxing authority thereof or therein, or as a result of any
official administrative pronouncement or judicial decision interpreting or
applying such laws or regulations, which amendment or change is effective or
such prospective change, pronouncement or decision is announced on or after the
date of issuance of the Preferred Securities of GBB Capital, there is more than
an insubstantial risk that (i) GBB Capital is, or will be within 90 days of the
date of such opinion of counsel, subject to United States Federal income tax
with respect to income received or accrued on the Securities, (ii) interest
payable by the Company on the Securities is not, or within 90 days of the date
of such opinion of counsel, will not be, deductible by the Company, in whole or
in part, for United States Federal income tax purposes or (iii) GBB Capital is,
or will be within 90 days of the date of such opinion of counsel, subject to
more than a de minimis amount of other taxes, duties or other governmental
charges.

                                      -3-

specified in Section 5.1, paragraphs (1) through (7), of the Indenture.

          (11) The portion of the principal amount of the Securities which shall
be payable upon declaration of acceleration of maturity thereof shall not be
other than the principal amount thereof, provided, that, if such acceleration is
declared by the Holders of at least 25% in aggregate liquidation amount of the
Preferred Securities of GBB Capital then outstanding, then, upon such
declaration of acceleration, the Securities which shall be payable shall be the
principal amount thereof plus accrued interest (including any Additional
Interest).

          (12) The Securities will be issued in fully registered form, without
coupons.  The Securities will not be issued in bearer form.

          (13) The amount of payments of principal of and any premium or
interest on the Securities will not be determined with reference to an index.

          (14) The Securities shall not be issued in the form of a temporary
Global Security (as defined below).

          (15) The Securities will initially be in certificated form registered
in the name of the name of Wilmington Trust Company, as Property Trustee (the
"Certificated Securities").  The Securities may, in the sole discretion of the
Company, be deposited with, and on behalf of, The Depository Trust Company, New
York, New York, as Depositary, and will be represented by a global security (a
"Global Security") registered in the name of a nominee of the Depositary.  If,
and so long as the Depositary or its nominee is the registered holder of any
Global Security, the Depositary or its nominee, as the case may be, will be
considered the sole Holder of the Securities of such series represented by such
Global Security for all purposes under the Indenture and the Securities.  The
Certificated Securities or the Global Securities, as the case may be, shall bear
no legends.

hereunder or with respect to the trust estate, except as otherwise required by
applicable law or as may be necessary to obtain prior to such execution and
delivery any licenses, consents or approvals required by applicable law or
otherwise.

          4.   The Depositor and the Trustees hereby authorize and direct the
Depositor, as the sponsor of the Trust, (i) to file with the Securities and
Exchange Commission (the "Commission") and execute, in each case on behalf of
the Trust, (a) the Registration Statement on Form S-1 (the "1933 Act

the rules and regulations of the Commission, an Exchange or state securities or
blue sky laws to be executed on behalf of the Trust by one or more of the
Trustees, each of the Trustees in such Trustee's capacity as a Trustee of the

the number of Trustees shall be such number as shall be fixed from time to time
by a written instrument signed by the Depositor which may increase or decrease
the number of Trustees; provided, however, that to the extent required by the

                           Distributions; Redemption

     Section 4.1. Distributions.

     (a) The Trust Preferred Securities represent undivided beneficial interests
in the Trust Property, and Distributions (including of Additional Amounts) will
be made on the Trust Preferred Securities at the rate and on the dates that
payments of interest (including of Additional Interest, as defined in the
Indenture) are made on the Debentures.  Accordingly:

     (i) Distributions on the Trust Preferred Securities shall be cumulative,
and will accumulate whether or not there are funds of the Trust available for
the payment of Distributions.  Distributions shall accrue from ___________,
1997, and, except in the event (and to the extent) that the Depositor exercises
its right to defer the payment of interest on the Debentures pursuant to the
Indenture, shall be payable quarterly in arrears on March 31, June 30, September
30 and December 31 of each year, commencing on ____________, 1997. If any date
on which a Distribution is otherwise payable on the Trust Preferred Securities
is not a Business Day, then the payment of such Distribution shall be made on
the next succeeding day that is a Business Day (and without any interest or
other payment in respect of any such delay) except that, if such Business Day is
in the next succeeding calendar year, payment of such Distribution shall be made
on the immediately preceding Business Day, in each case with the same force and
effect as if made on such date (each date on which distributions are payable in
accordance with this Section 4.1(a), a "Distribution Date").

     (ii) Assuming payments of interest on the Debentures are made when due (and
before giving effect to Additional Amounts, if applicable), Distributions on the
Trust Preferred Securities shall be payable at a rate of ____% per annum of the
Liquidation Amount of the Trust Preferred Securities.  The amount of
Distributions payable for any full period shall be computed on the basis of a
360-day year of twelve 30-day months.  The amount of Distributions for any
partial period shall be computed on the basis of the number of days elapsed in a
360-day year of twelve 30-day months.  The amount of Distributions payable for
any period shall include the Additional Amounts, if any.

     (iii) Distributions on the Trust Preferred Securities shall be made by the
Property Trustee from the Payment Account and shall be payable on each
Distribution Date only to the 

                                      17
<PAGE>
 
extent that the Trust has funds then on hand and available in the Payment
Account for the payment of such Distributions.

     (b) Distributions on the Trust Preferred Securities with respect to a
Distribution Date shall be payable to the Holders thereof as they appear on the
Securities Register for the Trust Preferred Securities on the relevant record
date, which shall be one Business Day prior to such Distribution Date; provided,
however, that in the event that the Preferred Securities do not remain in book-
entry-only form, the relevant record date shall be the date 15 days prior to the
relevant Distribution Date.

     Section 4.2. Redemption.

     (a) On each Debenture Redemption Date and on the stated maturity of the
Debentures, the Trust will be required to redeem, subject to Section 4.3, a Like
Amount of Trust Preferred Securities at the Redemption Price.

     (b) Notice of redemption shall be given by the Property Trustee by first-
class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior
to the Redemption Date to each Holder of Trust Preferred Securities to be
redeemed, at such Holder's address appearing in the Security Register.  All
notices of redemption shall state:

     (i) the Redemption Date;

     (ii) the Redemption Price;

     (iii) the CUSIP number;

     (iv) if less than all the Outstanding Trust Preferred Securities are to be
redeemed, the identification and the total Liquidation Amount of the particular
Trust Preferred Securities to be redeemed; and

     (v) that on the Redemption Date the Redemption Price will become due and
payable upon each such Trust Security to be redeemed and that Distributions
thereon will cease to accrue on and after said date.

     (c) The Trust Preferred Securities redeemed on each Redemption Date shall
be redeemed at the Redemption Price with the proceeds from the contemporaneous
redemption of Debentures. Redemptions of the Trust Preferred Securities shall be
made and the Redemption Price shall be payable on each Redemption Date only to
the extent that the Trust has funds then on hand and available in the Payment
Account for the payment of such Redemption Price.

     (d) If the Property Trustee gives a notice of redemption in respect of any
Preferred Securities, then, by 12:00 noon, New York City time, on the Redemption
Date, subject to Section 4.2(c), with respect to Preferred Securities held in
book-entry form, the Property Trustee will irrevocably deposit with the Clearing
Agency for the Preferred Securities funds sufficient to pay the applicable

                                      18
<PAGE>
 
Redemption Price and will give such Clearing Agency irrevocable instructions and
authority to pay the Redemption Price to the holders thereof.  With respect to
Preferred Securities held in certificated form, the Property Trustee, subject to
Section 4.2(c), will irrevocably deposit with the Paying Agent funds sufficient
to pay the applicable Redemption Price and will give the Paying Agent
irrevocable instructions and authority to pay the Redemption Price to the
Holders thereof upon surrender of their Preferred Securities Certificates.
Notwithstanding the foregoing, Distributions payable on or prior to the
Redemption Date for any Trust Preferred Securities called for redemption shall
be payable to the Holders of such Trust Preferred Securities as they appear on
the Register for the Trust Preferred Securities on the relevant record dates for
the related Distribution Dates.  If notice of redemption shall have been given
and funds deposited as required, then upon the date of such deposit, all rights
of Securityholders holding Trust Preferred Securities so called for redemption
will cease, except the right of such Securityholders to receive the Redemption
Price and any Distribution payable on or prior to the Redemption Date, but
without interest, and such Securities will cease to be outstanding. In the event
that any date on which any Redemption Price is payable is not a Business Day,
then payment of the Redemption Price payable on such date will be made on the
next succeeding day that is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day falls
in the next calendar year, such payment will be made on he immediately preceding
Business Day, in each case, with the same force and effect as if made on such
date.  In the event that payment of the Redemption Price in respect of any Trust
Preferred Securities called for redemption is improperly withheld or refused and
not paid either by the Trust or by the Depositor pursuant to the Guarantee,
Distributions on such Trust Preferred Securities will continue to accrue, at the
then applicable rate, from the Redemption Date originally established by the
Trust for such Trust Preferred Securities to the date such Redemption Price is
actually paid, in which case the actual payment date will be the date fixed for
redemption for purposes of calculating the Redemption Price.

     (e) Payment of the Redemption Price on the Trust Preferred Securities shall
be made to the recordholders thereof as they appear on the Securities Register
for the Trust Preferred Securities on the relevant record date, which shall be
one Business Day prior to the relevant Redemption Date; provided, however, that
in the event that the Preferred Securities do not remain in book-entry-only
form, the relevant record date shall be the date fifteen days prior to the
relevant Redemption Date.

     (f) Subject to Section 4.3(a), if less than all the Outstanding Trust
Preferred Securities are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of Trust Preferred Securities to be redeemed shall be
allocated on a pro rata basis (based on Liquidation Amounts) among the Common
Securities and the Preferred Securities.  The particular Preferred Securities to
be redeemed shall be selected on a pro rata basis (based upon Liquidation
Amounts) not more than 60 days prior to the Redemption Date by the Property
Trustee from the Outstanding Preferred Securities not previously called for
redemption, by such method (including, without limitation, by lot) as the
Property Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions (equal to $25 or an integral multiple of
$25 in excess thereof) of the Liquidation Amount of Preferred Securities of a
denomination larger than $25.  The Property Trustee shall promptly notify the
Security Registrar in writing of the Preferred Securities selected for
redemption and, in the case of any Preferred Securities selected for partial
redemption, the Liquidation Amount thereof to be redeemed.  For all purposes of
this Trust Agreement, unless the 

                                      19
<PAGE>
 
context otherwise requires, all provisions relating to the redemption of
Preferred Securities shall relate, in the case of any Preferred Securities
redeemed or to be redeemed only in part, to the portion of the Liquidation
Amount of Preferred Securities that has been or is to be redeemed.

     Section 4.3. Subordination of Common Securities.

     (a) Payment of Distributions (including Additional Amounts, if applicable)
on, and the Redemption Price of, the Trust Preferred Securities, as applicable,
shall be made, subject to Section 4.2(f), pro rata among the Common Securities
and the Preferred Securities based on the Liquidation Amount of the Trust
Preferred Securities; provided, however, that if on any Distribution Date or
Redemption Date any Event of Default resulting from a Debenture Event of Default
shall have occurred and be continuing, no payment of any Distribution (including
Additional Amounts, if applicable) on, or Redemption Price of, any Common
Security, and no other payment on account of the redemption, liquidation or
other acquisition of Common Securities, shall be made unless payment in full in
cash of all accumulated and unpaid Distributions (including Additional Amounts,
if applicable) on all Outstanding Preferred Securities for all Distribution
periods terminating on or prior thereto, or in the case of payment of the
Redemption Price the full amount of such Redemption Price on all Outstanding
Preferred Securities, shall have been made or provided for, and all funds
immediately available to the Property Trustee shall first be applied to the
payment in full in cash of all Distributions (including Additional Amounts, if
applicable) on, or the Redemption Price of, Preferred Securities then due and
payable.

     (b) In the case of the occurrence of any Event of Default resulting from
any Debenture Event of Default, the Holder of Common Securities will be deemed
to have waived any right to act with respect to any such Event of Default under
this Trust Agreement until the effect of all such Events of Default with respect
to the Preferred Securities have been cured, waived or otherwise eliminated.
Until any such Event of Default under this Trust Agreement with respect to the
Preferred Securities has been so cured, waived or otherwise eliminated, the
Property Trustee shall act solely on behalf of the Holders of the Preferred
Securities and not the Holder of the Common Securities, and only the Holders of
the Preferred Securities will have the right to direct the Property Trustee to
act on their behalf.

     Section 4.4. Payment Procedures.

     Payments of Distributions (including Additional Amounts, if applicable) in
respect of the Preferred Securities shall be made by check mailed to the address
of the Person entitled thereto as such address shall appear on the Securities
Register or, if the Preferred Securities are held by a Clearing Agency, such
Distributions shall be made to the Clearing Agency in immediately available
funds, which shall credit the relevant Persons' accounts at such Clearing Agency
on the applicable Distribution Dates.  Payments in respect of the Common
Securities shall be made in such manner as shall be mutually agreed between the
Property Trustee and the Common Securityholder.

Securities Certificates as herein provided.  The Bank shall be the initial
Securities Registrar.

     Upon surrender for registration of transfer of any Preferred Securities
Certificate at the office or agency maintained pursuant to Section 5.8, the
Administrative Trustees or any one of them shall execute and deliver, in the
name of the designated transferee or transferees, one or more new Preferred
Securities Certificates in authorized denominations of a like aggregate
Liquidation Amount dated the date of execution by such Administrative Trustee or
Trustees.

     The Securities Registrar shall not be required to register the transfer of
any Preferred Securities that have been called for redemption.  At the option of
a Holder, Preferred Securities Certificates may be exchanged for other Preferred
Securities Certificates in authorized denominations of the same class and of a
like aggregate Liquidation Amount upon surrender of the Preferred Securities
Certificates to be exchanged at the office or agency maintained pursuant to
Section 5.8.

     Every Preferred Securities Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to an Administrative Trustee and the
Securities Registrar duly executed by the Holder or his attorney duly authorized
in writing.  Each Preferred Securities Certificate surrendered for registration
of transfer or exchange shall be canceled and subsequently disposed of by an
Administrative Trustee in accordance with such Person's customary practice.  The
Trust shall not be required to (i) issue, 

                                      22
<PAGE>
 
register the transfer of, or exchange any Preferred Securities during a period
beginning at the opening of business 15 calendar days before the date of mailing
of a notice of redemption of any Preferred Securities called for redemption and
ending at the close business on the day of such mailing or (ii) register the
transfer of or exchange any Preferred Securities so selected for redemption, in
whole or in part, except the unredeemed portion of any such Preferred Securities
being redeemed in part.

     No service charge shall be made for any registration of transfer or
exchange of Preferred Securities Certificates, but the Securities Registrar may
require payment of a sum sufficient to cover any tax or governmental charge that
may be imposed in connection with any transfer or exchange of Preferred
Securities Certificates.

     Section 5.5. Mutilated, Destroyed, Lost or Stolen Trust Preferred
Securities Certificates.

     If (a) any mutilated Trust Preferred Securities Certificate shall be
surrendered to the Securities Registrar, or if the Securities Registrar shall
receive evidence to its satisfaction of the destruction, loss or theft of any
Trust Preferred Securities Certificate and (b) there shall be delivered to the
Securities Registrar and the Administrative Trustees such security or indemnity
as may be required by them to save each of them harmless, then in the absence of
notice that such Trust Preferred Securities Certificate shall have been acquired
by a bona fide purchaser, the Administrative Trustees, or any one of them, on
behalf of the Trust shall execute and make available for delivery, in exchange
for or in lieu of any such mutilated, destroyed, lost or stolen Trust Preferred
Securities Certificate, a new Trust Preferred Securities Certificate of like
class, tenor and denomination.  In connection with the issuance of any new Trust
Preferred Securities Certificate under this Section, the Administrative Trustees
or the Securities Registrar may require the payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in connection
therewith.  Any duplicate Trust Preferred Securities Certificate issued pursuant
to this Section shall constitute conclusive evidence of an undivided beneficial
interest in the assets of the Trust, as if originally issued, whether or not the
lost, stolen or destroyed Trust Preferred Securities Certificate shall be found
at any time.

     Section 5.6. Persons Deemed Securityholders.

     The Trustees or the Securities Registrar shall treat the Person in whose
name any Trust Preferred Securities Certificate shall be registered in the
Securities Register as the owner of such Trust Preferred Securities Certificate
for the purpose of receiving Distributions and for all other purposes
whatsoever, and neither the Trustees nor the Securities Registrar shall be bound
by any notice to the contrary.

     Section 5.7. Access to List of Securityholders' Names and Addresses.

     At any time when the Property Trustee is not also acting as the Securities
Registrar, the Administrative Trustees or the Depositor shall furnish or cause
to be furnished to the Property Trustee (a) semi-annually on or before January 1
and July 1 in each year, a list, in such form as the Property Trustee may
reasonably require, of the names and addresses of the Security holders as of the
most recent Record Date and (b) promptly after receipt by any Administrative
Trustee or the Depositor of a request therefor from the Property Trustee, such
other information as the Property 

                                      23
<PAGE>
 
Trustee may reasonably require in order to enable the Property Trustee to
discharge its obligations under this Trust Agreement, in each case to the extent
such information is in the possession or control of the Administrative Trustees
or the Depositor and is not identical to a previously supplied list or has not
otherwise been received by the Property Trustee in its capacity as Securities
Registrar. The rights of Security holders to communicate with other Security
holders with respect to their rights under this Trust Agreement or under the
Trust Preferred Securities, and the corresponding rights of the Trustee shall be
as provided in the Trust Indenture Act. Each Holder, by receiving and holding a
Trust Preferred Securities Certificate, and each Owner shall be deemed to have
agreed not to hold the Depositor, the Property Trustee or the Administrative
Trustees accountable by reason of the disclosure of its name and address,
regardless of the source from which such information was derived.

     Section 5.8. Maintenance of Office or Agency.

     The Administrative Trustees shall maintain an office or offices or agency
or agencies where Preferred Securities Certificates may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Trustees in respect of the Trust Preferred Securities Certificates may be
served.  The Administrative Trustees initially designate the principal corporate
trust office of the Property Trustee, Rodney Square North, 1100 North Market
Street, Wilmington, Delaware 19890, Attention: Corporate Trust Administrator, as
the principal corporate trust office for such purposes.  The Administrative
Trustees shall give prompt written notice to the Depositor and to the
Securityholders of any change in the location of the Securities Register or any
such office or agency.

     Section 5.9. Appointment of Paying Agent.

     The Paying Agent shall make Distributions to Securityholders from the
Payment Account and shall report the amounts of such Distributions to the
Property Trustee and the Administrative Trustees.  Any Paying Agent shall have
the revocable power to withdraw funds from the Payment Account for the purpose
of making the Distributions referred to above.  The Administrative Trustees may
revoke such power and remove the Paying Agent if such Trustees determine in
their sole discretion that the Paying Agent shall have failed to perform its
obligations under this Trust Agreement in any material respect.  The Paying
Agent shall initially be the Property Trustee, and any co-paying agent chosen by
the Property Trustee, and acceptable to the Administrative Trustees and the
Depositor.  Any Person acting as Paying Agent shall be permitted to resign as
Paying Agent upon 30 days' written notice to the Administrative Trustees, the
Property Trustee and the Depositor. In the event that the Property Trustee shall
no longer be the Paying Agent or a successor Paying Agent shall resign or its
authority to act be revoked, the Administrative Trustees shall appoint a
successor that is acceptable to the Property Trustee and the Depositor to act as
Paying Agent (which shall be a bank or trust company).  The Administrative
Trustees shall cause such successor Paying Agent or any additional Paying Agent
appointed by the Administrative Trustees to execute and deliver to the Trustees
an instrument in which such successor Paying Agent or additional Paying Agent
shall agree with the Trustees that as Paying Agent, such successor Paying Agent
or additional Paying Agent will hold all sums, if any, held by it for payment to
the Securityholders in trust for the benefit of the Securityholders entitled
thereto until such sums shall be paid to such Securityholders. The Paying Agent
shall return all unclaimed funds to the Property Trustee and upon removal of a
Paying Agent 

                                      24
<PAGE>
 
such Paying Agent shall also return all funds in its possession to the Property
Trustee. The provisions of Sections 8.1, 8.3 and .6 herein shall apply to the
Bank also in its role as Paying Agent, for so long as the Bank shall act as
Paying Agent and, to the extent applicable, to any other paying agent appointed
hereunder. Any reference in this Agreement to the Paying Agent shall include any
co-paying agent unless the context requires otherwise.

     Section 5.10. Ownership of Common Securities by Depositor.

     At the Closing Date, the Depositor shall acquire and retain beneficial and
record ownership of the Common Securities.  To the fullest extent permitted by
law, other than a transfer in connection with a consolidation or merger of the
Depositor into another corporation, or any conveyance, transfer or lease by the
Depositor of its properties and assets substantially as an entirety to any
Person, pursuant to Section 8.1 of the Indenture, any attempted transfer of the
Common Securities shall be void.  The Administrative Trustees shall cause each
Common Securities Certificate issued to the Depositor to contain a legend
stating "THIS CERTIFICATE IS NOT TRANSFERABLE".

     Section 5.11. Book-Entry Preferred Securities Certificates; Common
Securities Certificate.

     (a) The Preferred Securities Certificates, upon original issuance, will be
issued in the form of a typewritten Preferred Securities Certificate or
Certificates representing Book-Entry Preferred Securities Certificates, to be
delivered to The Depository Trust Company, the initial Clearing Agency, by, or
on behalf of, the Trust.  Such Preferred Securities Certificate or Certificates
shall initially be registered on the Securities Register in the name of Cede &
Co., the nominee of the initial Clearing Agency, and no Owner will receive a
Definitive Preferred Securities Certificate representing such Owner's interest
in such Preferred Securities, except as provided in Section 5.13. Unless and
until Definitive Preferred Securities Certificates have been issued to Owners
pursuant to Section 5.13:

     (i) the provisions of this Section 5.11(a) shall be in full force and
effect;

     (ii) the Securities Registrar, the Paying Agent and the Trustees shall be
entitled to deal with the Clearing Agency for all purposes of this Trust
Agreement relating to the Book-Entry Preferred Securities Certificates
(including the payment of the Liquidation Amount of and Distributions on the
Preferred Securities evidenced by Book-Entry Preferred Securities Certificates)
the Book-Entry Preferred Securities Certificates and shall have no obligations
to the Owners thereof;

     (iii) to the extent that the provisions of this Section 5.11 conflict with
any other provisions of this Trust Agreement, the provisions of this Section
5.11 shall control; and

     (iv) the rights of the Owners of the Book-Entry Preferred Securities
Certificates shall be exercised only through the Clearing Agency and shall be
limited to those established by law and agreements between such Owners and the
Clearing Agency and/or the Clearing Agency Participants.  Pursuant to the
Certificate Depository Agreement, unless and until Definitive Preferred
Securities Certificates are issued pursuant to Section 5.13, the initial
Clearing Agency will make book-entry transfers among the Clearing Agency
Participants and receive 

                                      25
<PAGE>
 
and transmit payments on the Preferred Securities to such Clearing Agency
Participants. Any Clearing Agency designated pursuant here to will not be deemed
an agent of the Trustee for any purpose.

     (b) A single Common Securities Certificate representing the Common
Securities shall be issued to the Depositor in the form of a definitive Common
Securities Certificate.

     Section 5.12. Notices to Clearing Agency.

     To the extent that a notice or other communication to the Owners is
required under this Trust Agreement, unless and until Definitive Preferred
Securities Certificates shall have been issued to Owners pursuant to Section
5.13, the Trustees shall give all such notices and communications specified
herein to be given to Owners to the Clearing Agency, and shall have no
obligations to the Owners.

     Section 5.13. Definitive Preferred Securities Certificates.

     If (a) the Depositor advises the Trustees in writing that the Clearing
Agency is no longer willing or able to properly discharge its responsibilities
with respect to the Preferred Securities Certificates, and the Depositor is
unable to locate a qualified successor, (b) the Depositor at its option advises
the Trustees in writing that it elects to terminate the book-entry system
through the Clearing Agency or (c) after the occurrence of a Debenture Event of
Default, Owners of Preferred Securities Certificates representing beneficial
interests aggregating at least a majority of the Liquidation Amount advise the
Property Trustee in writing that the continuation of a book-entry system through
the Clearing Agency is no longer in the best interest of the Owners of Preferred
Securities Certificates, then the Property Trustee shall notify the Clearing
Agency and the Clearing Agency shall notify all Owners of Preferred Securities
Certificates and the other Trustees of the occurrence of any such event and of
the availability of the Definitive Preferred Securities Certificates to Owners
of such class or classes, as applicable, requesting the same.  Upon surrender to
the Property Trustee of the typewritten Preferred Securities Certificate or
Certificates representing the Book Entry Preferred Securities Certificates by
the Clearing Agency, accompanied by registration instructions, the
Administrative Trustees, or any one of them, shall execute the Definitive
Preferred Securities Certificates in accordance with the instructions of the
Clearing Agency.  Neither the Securities Registrar nor the Trustees shall be
liable for any delay in delivery of such instructions and may conclusively rely
on, and shall be protected in relying on, such instructions.  Upon the issuance
of Definitive Preferred Securities Certificates, the Trustees shall recognize
the Holders of the Definitive Preferred Securities Certificates as
Securityholders.  The Definitive Preferred Securities Certificates shall be
printed, lithographed or engraved or may be produced in any other manner as is
reasonably acceptable to the Administrative Trustees, as evidenced by the
execution thereof by the Administrative Trustees or any one of them.

     Section 5.14. Rights of Securityholders.

     (a) The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 2.9, and
the Securityholders shall not have any right or 

                                      26
<PAGE>
 
title therein other than the undivided beneficial interest in the assets of the
Trust conferred by their Trust Preferred Securities and they shall have no right
to call for any partition or division of property, profits or rights of the
Trust except as described below. The Trust Preferred Securities shall be
personal property giving only the rights specifically set forth therein and in
this Trust Agreement. The Trust Preferred Securities shall have no preemptive or
similar rights and when issued and delivered to Securityholders against payment
of the purchase price therefor will be fully paid and nonassessable by the
Trust. The Holders of the Trust Preferred Securities, in their capacities as
such, shall be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware.

     (b) For so long as any Preferred Securities remain Outstanding, if, upon a
Debenture Event of Default, the Debenture Trustee fails or the holders of not
less than 25% in principal amount of the outstanding Debentures fail to declare
the principal of all of the Debentures to be immediately due and payable, the
Holders of at least 25% in Liquidation Amount of the Preferred Securities then
Outstanding shall have such right by a notice in writing to the Depositor and
the Debenture Trustee; and upon any such declaration such principal amount of
and the accrued interest on all of the Debentures shall become immediately due
and payable, provided that the payment of principal and interest on such
Debentures shall remain subordinated to the extent provided in the Indenture.

     At any time after such a declaration of acceleration with respect to the
Debentures has been made and before a judgment or decree for payment of the
money due has been obtained by the Debenture Trustee as in the Indenture
provided, the Holders of a majority in Liquidation Amount of the Preferred
Securities, by written notice to the Property Trustee, the Depositor and the
Debenture Trustee, may rescind and annul such declaration and its consequences
if:

     (i) the Depositor has paid or deposited with the Debenture Trustee a sum
sufficient to pay

     (A) all overdue installments of interest (including any Additional Interest
(as defined in the Indenture)) on all of the Debentures,

     (B) the principal of (and premium, if any, on) any Debentures which have
become due otherwise than by such declaration of acceleration and interest
thereon at the rate borne by the Debentures, and

     (C) all sums paid or advanced by the Debenture Trustee under the Indenture
and the reasonable compensation, expenses, disbursements and advances of the
Debenture Trustee and the Property Trustee, their agents and counsel; and

     (ii) all Events of Default with respect to the Debentures, other than the
non-payment of the principal of the Debentures which has become due solely by
such acceleration, have been cured or waived as provided in Section 5.13 of the
Indenture.

     The holders of a majority in aggregate Liquidation Amount of the Preferred
Securities may, on behalf of the Holders of all the Preferred Securities, waive
any past default under the Indenture, 

                                      27
<PAGE>
 
except a default in the payment of principal or interest (unless such default
has been cured and a sum sufficient to pay all matured installments of interest
and principal due otherwise than by acceleration has been deposited with the
Debenture Trustee) or a default in respect of a covenant or provision which
under the Indenture cannot be modified or amended without the consent of the
holder of each outstanding Debenture. No such rescission shall affect any
subsequent default or impair any right consequent thereon.

     Upon receipt by the Property Trustee of written notice declaring such an
acceleration, or rescission and annulment thereof, by Holders of the Preferred
Securities all or part of which is represented by Book-Entry Preferred
Securities Certificates, a record date shall be established for determining
Holders of Outstanding Preferred Securities entitled to join in such notice,
which record date shall be at the close of business on the day the Property
Trustee receives such notice.  The Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to join in such
notice, whether or not such Holders remain Holders after such record date;
provided, that, unless such declaration of acceleration, or rescission and
annulment, as the case may be, shall have become effective by virtue of the
requisite percentage having joined in such notice prior to the day which is 90
days after such record date, such notice of declaration of acceleration, or
rescission and annulment, as the case may be, shall automatically and without
further action by any Holder be canceled and of no further effect.  Nothing in
this paragraph shall prevent a Holder, or a proxy of a Holder, from giving,
after expiration of such 90-day period, a new written notice of declaration of
acceleration, or rescission and annulment thereof, as the case may be, that is
identical to a written notice which has been canceled pursuant to the proviso to
the preceding sentence, in which event a new record date shall be established
pursuant to the provisions of this Section 5.14(b).

     (c) For so long as any Preferred Securities remain Outstanding, to the
fullest extent permitted by law and subject to the terms of this Trust Agreement
and the Indenture, upon a Debenture Event of Default specified in Section 5.1(1)
or 5.1(2) of the Indenture, any Holder of Preferred Securities shall have the
right to institute a proceeding directly against the Depositor, pursuant to
Section 5.8 of the Indenture, for enforcement of payment to such Holder of the
principal amount of or interest on Debentures having a principal amount equal to
the Liquidation Amount of the Preferred Securities of such Holder (a "Direct
Action").  Except as set forth in Section 5.14(b) and this Section 5.14(c), the
Holders of Preferred Securities shall have no right to exercise directly any
right or remedy available to the holders of, or in respect of, the Debentures.


                                  ARTICLE VI.

                   Acts of Securityholders; Meetings; Voting

     Section 6.1. Limitations on Voting Rights.

     (a) Except as provided in this Section, in Sections 5.14, 8.10 and 10.2 and
in the Indenture and as otherwise required by law, no Holder of Preferred
Securities shall have any right to vote or in any manner otherwise control the
administration, operation and management of the Trust or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the 

                                      28
<PAGE>
 
Trust Preferred Securities Certificates, be construed so as to constitute the
Securityholders from time to time as partners or members of an association.

     (b) So long as any Debentures are held by the Property Trustee, the
Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or executing any
trust or power conferred on the Debenture Trustee with respect to such
Debentures, (ii) waive any past default which is waivable under Section 5.13 of
the Indenture, (iii) exercise any right to rescind or annul a declaration that
the principal of all the Debentures shall be due and payable or (iv) consent to
any amendment, modification or termination of the Indenture or the Debentures,
where such consent shall be required, without, in each case, obtaining the prior
approval of the Holders of at least a majority in Liquidation Amount of all
Outstanding Preferred Securities, provided, however, that where a consent under
the Indenture would require the consent of each Holder of Debentures affected
thereby, no such consent shall be given by the Property Trustee without the
prior written consent of each Holder of Preferred Securities.  The Trustees
shall not revoke any action previously authorized or approved by a vote of the
Holders of Preferred Securities, except by a subsequent vote of the Holders of
Preferred Securities.  The Property Trustee shall notify all Holders of the
Preferred Securities of any notice of default received from the Debenture
Trustee with respect to the Debentures.  In addition to obtaining the foregoing
approvals of the Holders of the Preferred Securities, prior to taking any of the
foregoing actions, the Trustees shall, at the expense of the Depositor, obtain
an Opinion of Counsel experienced in such matters to the effect that such action
shall not cause the Trust to fail to be classified as a grantor trust for United
States Federal income tax purposes.

     (c) If any proposed amendment to the Trust Agreement provides for, or the
Trustees otherwise propose to effect, (i) any action that would adversely affect
in any material respect the powers, preferences or special rights of the
Preferred Securities, whether by way of amendment to the Trust Agreement or
otherwise, or (ii) the dissolution, winding-up or termination of the Trust,
other than pursuant to the terms of this Trust Agreement, then the Holders of
Outstanding Preferred Securities as a class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of the Holders of at least a majority in Liquidation
Amount of the Outstanding Preferred Securities.  Notwithstanding any other
provision of this Trust Agreement, no amendment to this Trust Agreement may be
made if, as a result of such amendment, it would cause the Trust to fail to be
classified as a grantor trust for United States Federal income tax purposes.

     Section 6.2. Notice of Meetings.

     Notice of all meetings of the Preferred Securityholders, stating the time,
place and purpose of the meeting, shall be given by the Property Trustee
pursuant to Section 10.8 to each Preferred Securityholder of record, at his
registered address, at least 15 days and not more than 90 days before the
meeting.  At any such meeting, any business properly before the meeting may be
so considered whether or not stated in the notice of the meeting.  Any adjourned
meeting may be held as adjourned without further notice.

                                      29
<PAGE>
 
     Section 6.3. Meetings of Preferred Securityholders.

     No annual meeting of Securityholders is required to be held.  The
Administrative Trustees, however, shall call a meeting of Preferred
Securityholders to vote on any matter upon the written request of Holders of
record of 25% of the Outstanding Preferred Securities (based upon their
Liquidation Amount) and the Administrative Trustees or the Property Trustee may,
at any time in their discretion, call a meeting of Preferred Securityholders to
vote on any matters as to which Preferred Securityholders are entitled to vote.

     Holders of record of 50% of the Outstanding Preferred Securities (based
upon their Liquidation Amount), present in person or by proxy, shall constitute
a quorum at any meeting of Securityholders.

     If a quorum is present at a meeting, an affirmative vote by the Preferred
Securityholders of record present, in person or by proxy, holding more than a
majority of the Preferred Securities (based upon their Liquidation Amount) held
by the Preferred Securityholders of record present, either in person or by
proxy, at such meeting shall constitute the action of the Preferred
Securityholders, unless this Trust Agreement requires a greater number of
affirmative votes.

     Section 6.4. Voting Rights.

     Securityholders shall be entitled to one vote for each $25 of Liquidation
Amount represented by their Trust Preferred Securities in respect of any matter
as to which such Securityholders are entitled to vote.

     Section 6.5. Proxies, etc.

     At any meeting of Securityholders, any Securityholder entitled to vote
thereat may vote by proxy, provided that no proxy shall be voted at any meeting
unless it shall have been placed on file with the Administrative Trustees, or
with such other officer or agent of the Trust as the Administrative Trustees may
direct, for verification prior to the time at which such vote shall be taken.
Pursuant to a resolution of the Property Trustee, proxies may be solicited in
the name of the Property Trustee or one or more officers of the Property
Trustee.  Only Securityholders of record shall be entitled to vote.  When Trust
Preferred Securities are held jointly by several persons, any one of them may
vote at any meeting in person or by proxy in respect of such Trust Preferred
Securities, but if more than one of them shall be present at such meeting in
person or by proxy, and such joint owners or their proxies so present disagree
as to any vote to be cast, such vote shall not be received in respect of such
Trust Preferred Securities.  A proxy purporting to be executed by or on behalf
of a Securityholder shall be deemed valid unless challenged at or prior to its
exercise, and the burden of proving invalidity shall rest on the challenger.  No
proxy shall be valid more than three years after its date of execution.

     Section 6.6. Securityholder Action by Written Consent.

                                      30
<PAGE>
 
     Any action which may be taken by Securityholders at a meeting may be taken
without a meeting if Securityholders holding more than a majority of all
Outstanding Trust Preferred Securities (based upon their aggregate Liquidation
Amount) entitled to vote in respect of such action (or such larger proportion
thereof as shall be required by any express provision of this Trust Agreement)
shall consent to the action in writing (based upon their aggregate Liquidation
Amount).

     Section 6.7. Record Date for Voting and Other Purposes.

     For the purposes of determining the Securityholders who are entitled to
notice of and to vote at any meeting or by written consent, or to participate in
any Distribution on the Trust Preferred Securities in respect of which a record
date is not otherwise provided for in this Trust Agreement, or for the purpose
of any other action, the Administrative Trustees may from time to time fix a
date, not more than 90 days prior to the date of any meeting of Securityholders
or the payment of a Distribution or other action, as the case may be, as a
record date for the determination of the identity of the Securityholders of
record for such purposes.

     Section 6.8. Acts of Securityholders.

     Any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Trust Agreement to be given, made or
taken by Securityholders or Owners may be embodied in and evidenced by one or
more instruments of substantially similar tenor signed by such Securityholders
or Owners in person or by an agent duly appointed in writing; and, except as
otherwise expressly provided herein, such action shall become effective when
such instrument or instruments are delivered to an Administrative Trustee.  Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Securityholders or
Owners signing such instrument or instruments.  Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Trust Agreement and (subject to Section 8.1) conclusive in favor
of the Trustees, if made in the manner provided in this Section.

     The fact and date of the execution by any Person of any such instrument or
writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof.  Where such execution is
by a signer acting in a capacity other than his individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his
authority.  The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which any Trustee receiving the same deems sufficient.

     The ownership of Preferred Securities shall be proved by the Securities
Register.

     Any request, demand, authorization, direction, notice, consent, waiver or
other Act of the Securityholder of any Trust Security shall bind every future
Securityholder of the same Trust Security and the Securityholder of every Trust
Security issued upon the registration of transfer thereof or in exchange
therefor or in lieu thereof in respect of anything done, omitted or suffered to
be done by 

                                      31
<PAGE>
 
the Trustees or the Trust in reliance thereon, whether or not notation of such
action is made upon such Trust Security.

     Without limiting the foregoing, a Securityholder entitled hereunder to take
any action hereunder with regard to any particular Trust Security may do so with
regard to all or any part of the Liquidation Amount of such Trust Security or by
one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any part of such liquidation amount.

     If any dispute shall arise between the Securityholders and the
Administrative Trustees or among such Securityholders or Trustees with respect
to the authenticity, validity or binding nature of any request, demand,
authorization, direction, consent, waiver or other Act of such Securityholder or
Trustee under this Article VI, then the determination of such matter by the
Property Trustee shall be conclusive with respect to such matter.

     A Securityholder may institute a legal proceeding directly against the
Depositor under the Guarantee to enforce its rights under the Guarantee without
first instituting a legal proceeding against the Guarantee Trustee (as defined
in the Guarantee), the Trust or any Person.

     Section 6.9. Inspection of Records.

     Upon reasonable notice to the Administrative Trustees and the Property
Trustee, the records of the Trust shall be open to inspection by Securityholders
during normal business hours for any purpose reasonably related to such

                                 ARTICLE VIII.

                                 The Trustees

     Section 8.1. Certain Duties and Responsibilities.

     (a) The duties and responsibilities of the Trustees shall be as provided by
this Trust Agreement and, in the case of the Property Trustee, by the Trust
Indenture Act.  Notwithstanding the foregoing, no provision of this Trust
Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any of their
duties hereunder, or in the exercise of any of their rights or powers, if they
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it.  Whether or not therein expressly so provided, every provision of this Trust
Agreement relating to the conduct or affecting the liability of or affording
protection to the Trustees shall be subject to the provisions of this Section.
Nothing in this Trust Agreement shall be construed to release an Administrative
Trustee from liability for its own gross negligent action, its own gross
negligent failure to act, or its own willful misconduct.  To the extent that, at
law or in equity, an Administrative Trustee has duties (including fiduciary
duties) and liabilities relating thereto to the Trust or to the Securityholders,
such Administrative Trustee shall not be liable to the Trust or to any
Securityholder for such Trustee's good faith reliance on the provisions of this
Trust Agreement.  The provisions of this Trust Agreement, to the extent that
they restrict the duties and liabilities of the Administrative Trustees
otherwise existing at law or in equity, are agreed by the Depositor and the
Securityholders to replace such other duties and liabilities of the
Administrative Trustees.

     (b) All payments made by the Property Trustee or a Paying Agent in respect
of the Trust Preferred Securities shall be made only from the revenue and
proceeds from the Trust Property and only to the extent that there shall be
sufficient revenue or proceeds from the Trust Property to enable the Property
Trustee or a Paying Agent to make payments in accordance with the terms hereof.
Each Securityholder, by its acceptance of a Trust Security, agrees that it will
look solely to the revenue and proceeds from the Trust Property to the extent
legally available for distribution to it as herein provided and that the
Trustees are not personally liable to it for any amount distributable in respect
of any Trust Security or for any other liability in respect of any Trust
Security.  This Section 8.1(b) 

                                      34
<PAGE>
 
does not limit the liability of the Trustees expressly set forth elsewhere in
this Trust Agreement or, in the case of the Property Trustee, in the Trust
Indenture Act.

     (c) No provision of this Trust Agreement shall be construed to relieve the
Property Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that:

     (i) the Property Trustee shall not be liable for any error of judgment made
in good faith by an authorized officer of the Property Trustee, unless it shall
be proved that the Property Trustee was negligent in ascertaining the pertinent
facts;

     (ii) the Property Trustee shall not be liable with respect to any action
taken or omitted to be taken by it in good faith in accordance with the
direction of the Holders of not less than a majority in Liquidation Amount of
the Trust Preferred Securities relating to the time, method and place of
conducting any proceeding for any remedy available to the Property Trustee, or
exercising any trust or power conferred upon the Property Trustee under this
Trust Agreement;

     (iii) the Property Trustee's sole duty with respect to the custody, safe
keeping and physical preservation of the Debentures and the Payment Account
shall be to deal with such Property in a similar manner as the Property Trustee
deals with similar property for its own account, subject to the protections and
limitations on liability afforded to the Property Trustee under this Trust
Agreement and the Trust Indenture Act;

     (iv) the Property Trustee shall not be liable for any interest on any money
received by it except as it may otherwise agree with the Depositor; and money
held by the Property Trustee need not be segregated from other funds held by it
except in relation to the Payment Account maintained by the Property Trustee
pursuant to Section 3.1 and except to the extent otherwise required by law; and

     (v) the Property Trustee shall not be responsible for monitoring the
compliance by the Administrative Trustees or the Depositor with their respective
duties under this Trust Agreement, nor shall the Property Trustee be liable for
the default or misconduct of the Administrative Trustees or the Depositor.

     Section 8.2. Certain Notices.

     (a) Within 5 Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee shall transmit, in
the manner and to the extent provided in Section 10.8, notice of such Event of
Default to the Securityholders, the Administrative Trustees and the Depositor,
unless the Event of Default shall have been cured or waived.   For purposes of
this Section the term "Event of Default" means any event that is, or after
notice or lapse of time or both would become, and Event of Default.

                                      35
<PAGE>
 
     (b) The Administrative Trustees shall transmit, to the Securityholders in
the manner and to the extent provided in Section 10.8, notice of the Depositor's
election to begin or further extend an Extension Period on the Debentures
(unless such election shall have been revoked) within the time specified for
transmitting such notice to the holders of the Debentures pursuant to the
Indenture as originally executed.

     Section 8.3. Certain Rights of Property Trustee.

     Subject to the provisions of Section 8.1:

     (a) the Property Trustee may rely and shall be protected in acting or
refraining from acting in good faith upon any resolution, Opinion of Counsel,
certificate, written representation of a Holder or transferee, certificate of
auditors or any other certificate, statement, instrument, opinion, report,
notice, request, consent, order, appraisal, bond, debenture, note, other
evidence of indebtedness or other paper or document believed by it to be genuine
and to have been signed or presented by the proper party or parties;

     (b) if (i) in performing its duties under this Trust Agreement the Property
Trustee is required to decide between alternative courses of action or (ii) in
construing any of the provisions of this Trust Agreement the Property Trustee
finds the same ambiguous or inconsistent with any other provisions contained
herein or (iii) the Property Trustee is unsure of the application of any
provision of this Trust Agreement, then, except as to any matter as to which the
Preferred Securityholders are entitled to vote under the terms of this Trust
Agreement, the Property Trustee shall deliver a notice to the Depositor
requesting written instructions of the Depositor as to the course of action to
be taken and the Property Trustee shall take such action, or refrain from taking
such action, as the Property Trustee shall be instructed in writing to take, or
to refrain from taking, by the Depositor; provided, however, that if the
Property Trustee does not receive such instructions of the Depositor within ten
Business Days after it has delivered such notice, or such reasonably shorter
period of time set forth in such notice (which to the extent practicable shall
not be less than two Business Days), it may, but shall be under no duty to, take
or refrain from taking such action not inconsistent with this Trust Agreement as
it shall deem advisable and in the best interests of the Securityholders, in
which event the Property Trustee shall have no liability except for its own bad
faith, negligence or willful misconduct;

     (c) any direction or act of the Depositor or the Administrative Trustees
contemplated by this Trust Agreement shall be sufficiently evidenced by an
Officers' Certificate;

     (d) whenever in the administration of this Trust Agreement, the Property
Trustee shall deem it desirable that a matter be established before undertaking,
suffering or omitting any action hereunder, the Property Trustee (unless other
evidence is herein specifically prescribed) may, in the absence of bad faith on
its part, request and rely upon an Officers' Certificate which, upon receipt of
such request, shall be promptly delivered by the Depositor or the Administrative
Trustees;

                                      36
<PAGE>
 
     (e) the Property Trustee shall have no duty to see to any recording, filing
or registration of any instrument (including any financing or continuation
statement or any filing under tax or securities laws) or any rerecording,
refiling or registration thereof;

     (f) the Property Trustee may consult with counsel (which counsel may be
counsel to the Depositor or any of its Affiliates, and may include any of its
employees) and the advice of such counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in reliance thereon and in accordance with
such advice, such counsel may be counsel to the Depositor or any of its
Affiliates, and may include any of its employees; the Property Trustee shall
have the right at any time to seek instructions concerning the administration of
this Trust Agreement from any court of competent jurisdiction;

     (g) the Property Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Trust Agreement at the request or
direction of any of the Securityholders pursuant to this Trust Agreement, unless
such Securityholders shall have offered to the Property Trustee reasonable
security or indemnity against the costs, expenses and liabilities which might be
incurred by it in compliance with such request or direction;

     (h) the Property Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond,
debenture, note or other evidence of indebtedness or other paper or document,
unless requested in writing to do so by one or more Securityholders, but the
Property Trustee may make such further inquiry or investigation into such facts
or matters as it may see fit;

     (i) the Property Trustee may execute any of the trusts or powers hereunder
or perform any duties hereunder either directly or by or through its agents or
attorneys, provided that the Property Trustee shall be responsible for its own
negligence or recklessness with respect to selection of any agent or attorney
appointed by it hereunder;

     (j) whenever in the administration of this Trust Agreement the Property
Trustee shall deem it desirable to receive instructions with respect to
enforcing any remedy or right or taking any other action hereunder the Property
Trustee (i) may request instructions from the Holders of the Trust Preferred
Securities which instructions may only be given by the Holders of the same
proportion in Liquidation Amount of the Trust Preferred Securities as would be
entitled to direct the Property Trustee under the terms of the Trust Preferred
Securities in respect of such remedy, right or action, (ii) may refrain from
enforcing such remedy or right or taking such other action until such
instructions are received, and (iii) shall be protected in acting in accordance
with such instructions; and

     (k) except as otherwise expressly provided by this Trust Agreement, the
Property Trustee shall not be under any obligation to take any action that is
discretionary under the provisions of this Trust Agreement.

     No provision of this Trust Agreement shall be deemed to impose any duty or
obligation on the Property Trustee to perform any act or acts or exercise any
right, power, duty or obligation conferred or imposed on it, in any jurisdiction
in which it shall be illegal, or in which the Property 

                                      37
<PAGE>
 
Trustee shall be unqualified or incompetent in accordance with applicable law,
to perform any such act or acts, or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Property Trustee
shall be construed to be a duty.

      Section 8.4. Not Responsible for Recitals or Issuance of Securities.

     The recitals contained herein and in the Trust Preferred Securities
Certificates shall be taken as the statements of the Trust, and the Trustees do
not assume any responsibility for their correctness. The Trustees shall not be
accountable for the use or application by the Depositor of the proceeds of the
Debentures.

      Section 8.5. May Hold Securities.

     Except as provided in the definition of the term "Outstanding" in Article
I, any Trustee or any other agent of any Trustee or the Trust, in its individual
or any other capacity, may become the owner or pledgee of Trust Preferred
Securities and, subject to Sections 8.8 and 8.13, may otherwise deal with the
Trust with the same rights it would have if it were not a Trustee or such other
agent.

     Section 8.6. Compensation; Indemnity; Fees.

     The Depositor agrees:

     (a) to pay to the Trustees from time to time reasonable compensation for
all services rendered by them hereunder (which compensation shall not be limited
by any provision of law in regard to the compensation of a trustee of an express
trust) as specified in a separate agreement between any of the Trustees and the
Depositor;

     (b) except as otherwise expressly provided herein, to reimburse the
Trustees upon request for all reasonable expenses, disbursements and advances
incurred or made by the Trustees in accordance with any provision of this Trust
Agreement (including the reasonable compensation and the expenses and
disbursements of its agents and counsel), except any such expense, disbursement
or advance as may be attributable to its negligence, bad faith or willfulness;
and

     (c) to the fullest extent permitted by applicable law, to indemnify and
hold harmless (i) each Trustee, (ii) any Affiliate of any Trustee, (iii) any
officer, director, shareholder, employee, representative or agent of any

(referred to herein as an "Indemnified Person") from and against any loss,
damage, liability, tax, penalty, expense or claim of any kind or nature
whatsoever incurred by such Indemnified Person by reason of the creation,
operation or termination of the Trust or any act or omission performed or

negligence, bad faith or willful misconduct with respect to such acts or
omissions.

                                      38
<PAGE>
 
     The provisions of this Section 8.6 shall survive the termination of this
Trust Agreement.

     No Trustee may claim any lien or charge on any Trust Property as a result
of any amount due pursuant to this Section 8.6.

     The Depositor and any Trustee may engage in or possess an interest in other
business ventures of any nature or description, independently or with others,
similar or dissimilar to the business of the Trust, and the Trust and the
Holders of Trust Preferred Securities shall have no rights by virtue of this
Trust Agreement in and to such independent ventures or the income or profits
derived therefrom, and the pursuit of any such venture, even if competitive with
the business of the Trust, shall not be deemed wrongful or improper.  Neither
the Depositor, nor any Trustee, shall be obligated to present any particular
investment or other opportunity to the Trust even if such opportunity is of a
character that, if presented to the Trust, could be taken by the Trust, and the
Depositor or any Trustee shall have the right to take for its own account
(individually or as a partner or fiduciary) or to recommend to others any such
particular investment or other opportunity.  Any Trustee may engage or be
interested in any financial or other transaction with the Depositor or any
Affiliate of the Depositor, or may act as depository for, trustee or agent for,
or act on any committee or body of holders of, securities or other obligations
of the Depositor or its Affiliates.

     Section 8.7. Corporate Property Trustee Required; Eligibility of Trustees.

     (a) There shall at all times be a Property Trustee hereunder with respect
to the Trust Preferred Securities.  The Property Trustee shall be a Person that
is eligible pursuant to the Trust Indenture Act to act as such and has a
combined capital and surplus of at least $50,000,000.  If any such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of its supervising or examining authority, then for the purposes of
this Section, the combined capital and surplus of such Person shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published.  If at any time the Property Trustee with respect to the
Trust Preferred Securities shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

     (b) There shall at all times be one or more Administrative Trustees
hereunder with respect to the Trust Preferred Securities.  Each Administrative
Trustee shall be either a natural person who is at least 21 years of age or a
legal entity that shall act through one or more persons authorized to bind that
entity.

     (c) There shall at all times be a Delaware Trustee with respect to the
Trust Preferred Securities.  The Delaware Trustee shall either be (i) a natural
person who is at least 21 years of age and a resident of the State of Delaware
or (ii) a legal entity with its principal place of business in the State of
Delaware and that otherwise meets the requirements of applicable Delaware law
that shall act through one or more persons authorized to bind such entity.

     Section 8.8. Conflicting Interests.

                                      39
<PAGE>
 
     If the Property Trustee has or shall acquire a conflicting interest within
the meaning of the Trust Indenture Act, the Property Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Trust
Agreement.

     Section 8.9. Co-Trustees and Separate Trustee.

     Unless an Event of Default shall have occurred and be continuing, at any
time or times, for the purpose of meeting the legal requirements of the Trust
Indenture Act or of any jurisdiction in which any part of the Trust Property may
at the time be located, the Depositor and the Administrative Trustees, by agreed
action of the majority of such Trustees, shall have power to appoint, and upon
the written request of the Administrative Trustees, the Depositor shall for such
purpose join with the Administrative Trustees in the execution, delivery, and
performance of all instruments and agreements necessary or proper to appoint,
one or more Persons approved by the Property Trustee either to act as co-
trustee, jointly with the Property Trustee, of all or any part of such Trust
Property, or to the extent required by law to act as separate trustee of any
such property, in either case with such powers as may be provided in the
instrument of appointment, and to vest in such Person or Persons in the capacity
aforesaid, any property, title, right or power deemed necessary or desirable,
subject to the other provisions of this Section.  If the Depositor does not join
in such appointment within 15 days after the receipt by it of a request so to
do, or in case a Debenture Event of Default has occurred and is continuing, the
Property Trustee alone shall have power to make such appointment.  Any co-
trustee or separate trustee appointed pursuant to this Section shall either be
(i) a natural person who is at least 21 years of age and a resident of the
United States or (ii) a legal entity with its principal place of business in the
United States that shall act through one or more persons authorized to bind such
entity.

     Should any written instrument from the Depositor be required by any co-
trustee or separate trustee so appointed for more fully confirming to such co-
trustee or separate trustee such property, title, right, or power, any and all
such instruments shall, on request, be executed, acknowledged and delivered by
the Depositor.

     Every co-trustee or separate trustee shall, to the extent permitted by law,
but to such extent only, be appointed subject to the following terms, namely:

     (a) The Trust Preferred Securities shall be executed and delivered and all
rights, powers, duties, and obligations hereunder in respect of the custody of
securities, cash and other personal property held by, or required to be
deposited or pledged with, the Trustees specified hereunder shall be exercised
solely by such Trustees and not by such co-trustee or separate trustee.

     (b) The rights, powers, duties, and obligations hereby conferred or imposed
upon the Property Trustee in respect of any property covered by such appointment
shall be conferred or imposed upon and exercised or performed by the Property
Trustee or by the Property Trustee and such co-trustee or separate trustee
jointly, as shall be provided in the instrument appointing such co-trustee or
separate trustee, except to the extent that under any law of any jurisdiction in
which any particular act is to be performed, the Property Trustee shall be
incompetent or unqualified to perform such act, 

                                      40
<PAGE>
 
in which event such rights, powers, duties and obligations shall be exercised
and performed by such co-trustee or separate trustee.

     (c) The Property Trustee at any time, by an instrument in writing executed
by it, with the written concurrence of the Depositor, may accept the resignation
of or remove any co-trustee or separate trustee appointed under this Section,
and, in case a Debenture Event of Default has occurred and is continuing, the
Property Trustee shall have power to accept the resignation of, or remove, any
such co-trustee or separate trustee without the concurrence of the Depositor.
Upon the written request of the Property Trustee, the Depositor shall join with
the Property Trustee in the execution, delivery and performance of all
instruments and agreements necessary or proper to effectuate such resignation or
removal.  A successor to any co-trustee or separate trustee so resigned or
removed may be appointed in the manner provided in this Section.

     (d) No co-trustee or separate trustee hereunder shall be personally liable
by reason of any act or omission of the Property Trustee or any other trustee
hereunder.

     (e) The Property Trustee shall not be liable by reason of any act of a co-
trustee or separate trustee.

     (f) Any Act of Holders delivered to the Property Trustee shall be deemed to
have been delivered to each such co-trustee and separate trustee.

     Section 8.10. Resignation and Removal; Appointment of Successor.

     No resignation or removal of any Trustee (the "Relevant Trustee") and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 8.11.

     Subject to the immediately preceding paragraph, the Relevant Trustee may
resign at any time by giving written notice thereof to the Securityholders.  If
the instrument of acceptance by the successor Trustee required by Section 8.11
shall not have been delivered to the Relevant Trustee within 30 days after the
giving of such notice of resignation, the Relevant Trustee may petition, at the
expense of the Trust, any court of competent jurisdiction for the appointment of
a successor Relevant Trustee.

     Unless a Debenture Event of Default shall have occurred and be continuing,
any Trustee may be removed at any time by Act of the Common Securityholder.  If
a Debenture Event of Default shall have occurred and be continuing, the Property
Trustee or the Delaware Trustee, or both of them, may be removed at such time by
Act of the Holders of a majority in Liquidation Amount of the Preferred
Securities, delivered to the Relevant Trustee (in its individual capacity and on
behalf of the Trust).  In no event will the Holders of the Preferred Securities
have the right to vote to appoint, remove or replace the Administrative Trustee.
An Administrative Trustee may be removed by the Common Securityholder at any
time.

                                      41
<PAGE>
 
     If any Trustee shall resign, be removed or become incapable of acting as
Trustee, or if a vacancy shall occur in the office of any Trustee for any cause,
at a time when no Debenture Event of Default shall have occurred and be
continuing, the Common Securityholder, by Act of the Common Securityholder
delivered to the retiring Trustee, shall promptly appoint a successor Trustee or
Trustees, and the retiring Trustee shall comply with the applicable requirements
of Section 8.11. If the Property Trustee or the Delaware Trustee shall resign,
be removed or become incapable of continuing to act as the Property Trustee or
the Delaware Trustee, as the case may be, at a time when a Debenture Event of
Default shall have occurred and be continuing, the Preferred Securityholders, by
Act of the Securityholders of a majority in Liquidation Amount of the Preferred
Securities then Outstanding delivered to the retiring Relevant Trustee, shall
promptly appoint a successor Relevant Trustee or Trustees, and such successor
Trustee shall comply with the applicable requirements of Section 8.11.  If an
Administrative Trustee shall resign, be removed or become incapable of acting as
Administrative Trustee, at a time when a Debenture Event of Default shall have
occurred and be continuing, the Common Securityholder by Act of the Common
Securityholder delivered to the Administrative Trustee shall promptly appoint a
successor Administrative Trustee or Administrative Trustees and such successor
Administrative Trustee or Trustees shall comply with the applicable requirements
of Section 8.11.  If no successor Relevant Trustee shall have been so appointed
by the Common Securityholder or the Preferred Securityholders and accepted
appointment in the manner required by Section 8.11, any Securityholder who has
been a Securityholder of Trust Preferred Securities for at least six months may,
on behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Relevant Trustee.

     The Property Trustee shall give notice of each resignation and each removal
of a Trustee and each appointment of a successor Trustee to all Securityholders
in the manner provided in Section 10.8 and shall give notice to the Depositor.
Each notice shall include the name of the successor Relevant Trustee and the
address of its Corporate Trust Office if it is the Property Trustee.

     Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative Trustee or a Delaware Trustee who is
a natural person dies or becomes, in the opinion of the Depositor, incompetent
or incapacitated, the vacancy created by such death, incompetence or incapacity
may be filled by (a) the unanimous act of the remaining Administrative Trustees
if there are at least two of them or (b) otherwise by the Depositor (with the
successor in each case being a Person who satisfies the eligibility requirement

wherein each successor Relevant Trustee shall accept such appointment and which
(a) shall contain such provisions as shall be necessary or desirable to transfer
and confirm to, and to vest in, each successor Relevant Trustee all the rights,
powers, trusts and duties of the retiring Relevant Trustee with respect to the
Trust Preferred Securities and the Trust and (b) shall add to or change any of
the provisions of this Trust Agreement as shall be necessary to provide for or
facilitate the administration of the Trust by more than one Relevant Trustee, it
being understood that nothing herein or in such amendment shall constitute such
Relevant Trustees co-trustees and upon the execution and delivery of such
amendment the resignation or removal of the retiring Relevant Trustee shall
become effective to the extent provided therein and each such successor Relevant
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Relevant Trustee; but,
on request of the Trust or any successor Relevant Trustee such retiring Relevant
Trustee shall duly assign, transfer and deliver to such successor Relevant
Trustee all Trust Property, all proceeds thereof and money held by such retiring

confirming to such successor Relevant Trustee all such rights, powers and trusts
referred to in the first or second preceding paragraph, as the case may be.

eligible under this Article.

     Any Person into which the Property Trustee or the Delaware Trustee may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such Relevant

all the corporate trust business of such Relevant Trustee, shall be the

or their creditors, the Property Trustee (irrespective of whether any
Distributions 

                                      43
<PAGE>
 
on the Trust Preferred Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the

past due Distributions) shall be entitled and empowered, to the fullest extent
permitted by law, by intervention in such proceeding or otherwise:

     (a) to file and prove a claim for the whole amount of any Distributions
owing and unpaid in respect of the Trust Preferred Securities and to file such
other papers or documents as may be necessary or advisable in order to have the

     (b) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Property Trustee and, in the event the Property Trustee shall
consent to the making of such payments directly to the Holders, to pay to the
Property Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Property Trustee, its agents and counsel, and
any other amounts due the Property Trustee.

     Nothing herein contained shall be deemed to authorize the Property Trustee
to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement adjustment or compensation affecting the Trust
Preferred Securities or the rights of any Holder thereof or to authorize the
Property Trustee to vote in respect of the claim of any Holder in any such
proceeding.

     Section 8.14. Reports by Property Trustee.

     (a) Not later than ___________ of each year commencing with ___________,
1997, the Property Trustee shall transmit to all Securityholders in accordance

Section 8.10.

     (c) The death, resignation, retirement, removal, bankruptcy, incompetence
or incapacity to perform the duties of a Trustee shall not operate to annul the

discharge all the duties imposed upon the Administrative Trustees by this Trust
Agreement.

      Section 8.18. Delegation of Power.

                                  ARTICLE IX.

                      Termination, Liquidation and Merger

     Section 9.1. Termination Upon Expiration Date.

     Unless terminated earlier, the Trust shall automatically terminate on
December 31, 2___ (the "Expiration Date"), following the distribution of the
Trust Property in accordance with Section 9.4.

     Section 9.2. Early Termination.

     The first to occur of any of the following events is an "Early Termination
Event":

     (a) the occurrence of a Bankruptcy Event in respect of, or the dissolution
or liquidation of, the Depositor;

     (b) the written direction to the Property Trustee from the Depositor at any
time to terminate the Trust and distribute Debentures to Securityholders in
exchange for a Like Amount of the Preferred Securities (which direction is
optional and wholly within the discretion of the Depositor);

     (c) the redemption of all of the Preferred Securities in connection with
the redemption of all the Debentures; and

     (d) the entry of an order for dissolution of the Trust by a court of
competent jurisdiction.

     Section 9.3. Termination.

                                      46
<PAGE>
 
     The respective obligations and responsibilities of the Trustees and the
Trust created and continued hereby shall terminate upon the latest to occur of
the following: (a) the distribution by the Property Trustee to Securityholders
upon the liquidation of the Trust pursuant to Section 9.4, or upon the
redemption of all of the Trust Preferred Securities pursuant to Section 4.2, of
all amounts required to be distributed hereunder upon the final payment of the
Trust Preferred Securities; (b) the payment of any expenses owed by the Trust;
and (c) the discharge of all administrative duties of the Administrative
Trustees, including the performance of any tax reporting obligations with
respect to the Trust or the Securityholders, and (d) the filing of a Certificate
of Cancellation by the Administrative Trustee under the Business Trust Act.

     Section 9.4. Liquidation.

     (a) If an Early Termination Event specified in clause (a), (b) or (d) of
Section 9.2 occurs or upon the Expiration Date, the Trust shall be liquidated by
the Trustees as expeditiously as the Trustees determine to be possible by
distributing, after satisfaction of liabilities to creditors of the Trust as
provided by applicable law, to each Securityholder a Like Amount of Debentures,
subject to Section 9.4(d).  Notice of liquidation shall be given by the Property
Trustee by first-class mail, postage prepaid mailed not later than 30 nor more
than 60 days prior to the Liquidation Date to each Holder of Trust Preferred
Securities at such Holder's address appearing in the Securities Register. All
notices of liquidation shall:

     (i) state the Liquidation Date;

     (ii) state that from and after the Liquidation Date, the Trust Preferred
Securities will no longer be deemed to be Outstanding and any Trust Preferred
Securities Certificates not surrendered for exchange will be deemed to represent
a Like Amount of Debentures; and

     (iii) provide such information with respect to the mechanics by which
Holders may exchange Trust Preferred Securities Certificates for certificates
representing the Like Amount of the Debentures, or if Section 9.4(d) applies
receive a Liquidation Distribution, as the Administrative Trustees or the
Property Trustee shall deem appropriate.

     (b) Except where Section 9.2(c) or 9.4(d) applies, in order to effect the
liquidation of the Trust and distribution of the Debentures to Securityholders,
the Administrative Trustees shall establish a record date for such distribution
(which shall be not more than 45 days prior to the Liquidation Date) and, either
itself acting as exchange agent or through the appointment of a separate
exchange agent, shall establish such procedures as it shall deem appropriate to
effect the distribution of Debentures in exchange for the Outstanding Trust
Preferred Securities Certificates.

     (c) Except where Section 9.2(c) or 9.4(d) applies, after the Liquidation
Date, (i) the Trust Preferred Securities will no longer be deemed to be
Outstanding, (ii) certificates representing a Like Amount of Debentures will be
issued to holders of Trust Preferred Securities Certificates, upon surrender of
such certificates to the Administrative Trustees or their agent for exchange,
(iii) the Depositor shall use its best efforts to have the Debentures listed on
the New York Stock Exchange or on such other exchange, interdealer quotation
system or self-regulatory organization as the 

                                      47
<PAGE>
 
Preferred Securities are then listed, (iv) any Trust Preferred Securities
Certificates not so surrendered for exchange will be deemed to represent a Like
Amount of Debentures, accruing interest at the rate provided for in the
Debentures from the last Distribution Date on which a Distribution was made on
such Trust Preferred Securities Certificates until such certificates are so
surrendered (and until such certificates are so surrendered, no payments of
interest or principal will be made to Holders of Debentures represented by such
certificates) and (v) all rights of Securityholders holding Trust Preferred
Securities will cease, except the right of such Securityholders to receive a
Like Amount of Debentures upon surrender of Trust Preferred Securities
Certificates.

     (d) In the event that, notwithstanding the other provisions of this Section
9.4, whether because of an order for dissolution entered by a court of competent
jurisdiction or otherwise, distribution of the Debentures in the manner provided
herein is determined by the Property Trustee not to be practical, the Trust
Property shall be liquidated, and the Trust shall be dissolved, wound-up or
terminated, by the Property Trustee in such manner as the Property Trustee
determines.  In such event, on the date of the dissolution, winding-up or other
termination of the Trust, Securityholders will be entitled to receive out of the
assets of the Trust available for distribution to Securityholders, after
satisfaction of liabilities to creditors of the Trust as provided by applicable
law, an amount equal to the Liquidation Amount per Trust Security plus
accumulated and unpaid Distributions thereon to the date of payment (such amount
being the "Liquidation Distribution"). If, upon any such dissolution, winding up
or termination, the Liquidation Distribution can be paid only in part because
the Trust has insufficient assets available to pay in full the aggregate
Liquidation Distribution, then, subject to the next succeeding sentence, the
amounts payable by the Trust on the Trust Preferred Securities shall be paid on
a pro rata basis (based upon Liquidation Amounts).  The holder of the Common
Securities will be entitled to receive Liquidation Distributions upon any such
dissolution, winding-up or termination pro rata (determined as aforesaid) with
Holders of Preferred Securities, except that, if a Debenture Event of Default
has occurred and is continuing, Holders of the Preferred Securities shall have a
priority over the Holders of Common Securities.

     Section 9.5. Mergers, Consolidations, Amalgamations or Replacements of the
                  Trust.

     The Trust may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other body, except pursuant
to this Section 9.5.  At the request of the Depositor, with the consent of the
Administrative Trustees and without the consent of the Holders of the Preferred
Securities, the Property Trustee or the Delaware Trustee, the Trust may merge
with or into, consolidate, amalgamate, or be replaced by or convey, transfer or
lease its properties and assets substantially as an entirety to a trust
organized as such under the laws of any State; provided, that (i) such successor
entity either (a) expressly assumes all of the obligations of the Trust with
respect to the Preferred Securities or (b) substitutes for the Preferred
Securities other securities having substantially the same terms as the Preferred
Securities (the "Successor Securities") so long as the Successor Securities rank
the same as the Preferred Securities rank in priority with respect to
distributions and payments upon liquidation, redemption and otherwise, (ii) the
Depositor expressly appoints a trustee of such successor entity possessing the
same powers and duties as the Property Trustee as the holder of the Debentures,
(iii) the Successor Securities are listed or traded, or any Successor Securities
will be listed upon notification of issuance, on any national securities
exchange or other organization on 

                                      48
<PAGE>
 
which the Preferred Securities are then listed or traded, if any, (iv) such
merger, consolidation, amalgamation, replacement, conveyance, transfer or lease
does not cause the Preferred Securities (including any Successor Securities) to
be downgraded by any nationally recognized statistical rating organization, (v)
such merger, consolidation, amalgamation, replacement, conveyance, transfer or
lease does not adversely affect the rights, preferences and privileges of the
holders of the Preferred Securities (including any Successor Securities) in any
material respect, (vi) such successor entity has a purpose identical to that of
the Trust, (vii) prior to such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease, the Depositor has received an Opinion of Counsel
to the effect that (a) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not adversely affect the rights, preferences
and privileges of the holders of the Preferred Securities (including any
Successor Securities) in any material respect, and (b) following such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease, neither
the Trust nor such successor entity will be required to register as an
investment company under the 1940 Act and (viii) the Depositor owns all of the
Common Securities of such successor entity and guarantees the obligations of
such successor entity under the Successor Securities at least to the extent
provided by the Guarantee. Notwithstanding the foregoing, the Trust shall not,
except with the consent of holders of 100% in Liquidation Amount of the
Preferred Securities, consolidate, amalgamate, merge with or into, or be
replaced by or convey, transfer or lease its properties and assets substantially
as an entirety to any other entity or permit any other entity to consolidate,
amalgamate, merge with or into, or replace it if such consolidation,
amalgamation, merger, replacement, conveyance, transfer or lease would cause the
Trust or the successor entity to be classified as other than a grantor trust for
United States Federal income tax purposes. [See Prospectus description.]

     Section 10.1. Limitation of Rights of Securityholders.

     The death or incapacity of any person having an interest, beneficial or
otherwise, in Trust Preferred Securities shall not operate to terminate this
Trust Agreement, nor entitle the legal representatives or heirs of such person

or bring any proceeding in any court for a partition or winding up of the
arrangements contemplated hereby, nor otherwise affect the rights, obligations
and liabilities of the parties hereto or any of them.

of this Trust Agreement to such 

                                      49

extent as shall be necessary to ensure that the Trust will be classified for
United States Federal income tax purposes as a grantor trust at all times that
any Trust Preferred Securities are outstanding or to ensure that the Trust will
not be required to register as an investment company under the 1940 Act;
provided, however, that in the case of clause (i), such action shall not
adversely affect in any material respect the interests of any Securityholder,
and any amendments of this Trust Agreement shall become effective when notice
thereof is given to the Securityholders.

     (b) Except as provided in Section 10.2(c) hereof, any provision of this

consent of Trust Securityholders representing not less than a majority (based
upon Liquidation Amounts) of the Trust Preferred Securities then Outstanding and
(ii) receipt by the Trustees of an Opinion of Counsel to the effect that such

United States Federal income tax purposes or the Trust's exemption from status
of an investment company under the 1940 Act.

Securities as of a specified date or (ii) restrict the right of a Securityholder
to institute suit for the enforcement of any such payment on or after such date;
notwithstanding any other provision herein, without the unanimous consent of the
Securityholders (such consent being obtained in accordance with Section 6.3 or
6.6 hereof), this paragraph (c) of this Section 10.2 may not be amended.

     (d) Notwithstanding any other provisions of this Trust Agreement, no
Trustee shall enter into or consent to any amendment to this Trust Agreement
which would cause the Trust to fail or cease to qualify for the exemption from
status of an investment company under the 1940 Act or fail or cease to be
classified as a grantor trust for United States Federal income tax purposes.

     (e) Notwithstanding anything in this Trust Agreement to the contrary,
without the consent of the Depositor, this Trust Agreement may not be amended in
a manner which imposes any additional obligation on the Depositor.

     (f) In the event that any amendment to this Trust Agreement is made, the
Administrative Trustees shall promptly provide to the Depositor a copy of such
amendment.

     (g) Neither the Property Trustee nor the Delaware Trustee shall be required

stating that any amendment to this Trust Agreement is in compliance with this
Trust Agreement.

Re:   GBB Capital I ____%  Cumulative Trust Preferred Securities

Ladies and Gentlemen:

     The purpose of this letter is to set forth certain matters relating to the
issuance and deposit with The Depository Trust Company ("DTC") of the GBB
Capital I ____% Cumulative Trust Preferred Securities, (the "Trust Preferred
Securities"), of GBB Capital I, a Delaware business trust (the "Issuer"), formed
pursuant to a Trust Agreement between Greater Bay Bancorp ("Greater Bay
Bancorp") and Wilmington Trust Company, as Property Trustee, Wilmington Trust
Company, as Delaware Trustee, and the Administrative Trustees named therein.
The payment of distributions on the Trust Preferred Securities, and payments due
upon liquidation of the Issuer or redemption of the Trust Preferred Securities,
to the extent the Issuer has funds available for the payment thereof are
guaranteed by Greater Bay Bancorp to the extent set forth in a Guarantee
Agreement dated ____________, 1997 by Greater Bay Bancorp with respect to the
Trust Preferred Securities.  Greater Bay Bancorp and the Issuer propose to sell
the Trust Preferred Securities to certain Underwriters (the "Underwriters")
pursuant to an Underwriting Agreement dated ____________, 1997 by and among the
Underwriters, the Issuer and Greater Bay Bancorp dated ____________, 1997, and
the Underwriters wish to take delivery of the Trust Preferred Securities through
DTC.  Wilmington Trust Company is acting as transfer agent and registrar with
respect to the Trust Preferred Securities (the "Transfer Agent and Registrar").

     To induce DTC to accept the Trust Preferred Securities as eligible for
deposit at DTC, and to act in accordance with DTC's rules with respect to the
Trust Preferred Securities, the Issuer, the Transfer Agent and Registrar and DTC
agree among each other as follows:

                                      56
<PAGE>
 
     1. Prior to the closing of the sale of the Trust Preferred Securities to
the Underwriters, which is expected to occur on or about ____________, 1997,
there shall be deposited with DTC one or more global certificates (individually
and collectively, the "Global Certificate") registered in the name of DTC's
Trust Preferred Securities nominee, Cede & Co., representing an aggregate of
____________ Trust Preferred Securities and bearing the following legend:

             Unless this certificate is presented by an authorized
             representative of The Depository Trust Company, a New York
             corporation ("DTC"), to the Issuer or its agent for registration of
             transfer, exchange, or payment, and any certificate issued is
             registered in the name of Cede & Co. or in such other name as is
             requested by an authorized representative of DTC (and any payment
             is made to Cede & Co. or to such other entity as is requested by an
             authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER
             USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
             inasmuch as the registered owner hereof, Cede & Co., has an
             interest herein.

     2. The Amended and Restated Trust Agreement of the Issuer provides for the
voting by holders of the Trust Preferred Securities under certain limited
circumstances.  The Issuer shall establish a record date for such purposes and
shall, to the extent possible, give DTC notice of such record date not less than
15 calendar days in advance of such record date.

     3. In the event of a stock split, conversion, recapitalization,
reorganization or any other similar transaction resulting in the cancellation of
all or any part of the Trust Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice of such event at least 5
business days prior to the effective date of such event.

     4. In the event of distribution on, or an offering or issuance of rights
with respect to, the Trust Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice specifying: (a) the amount
of and conditions, if any, applicable to the payment of any such distribution or
any such offering or issuance of rights; (b) any applicable expiration or
deadline date, or any date by which any action on the part of the holders of
Trust Preferred Securities is required; and (c) the date any required notice is
to be mailed by or on behalf of the Issuer to holders of Trust Preferred
Securities or published by or on behalf of the Issuer (whether by mail or
publication, the "Publication Date").  Such notice shall be sent to DTC by a
secure means (e.g., legible telecopy, registered or certified mail, overnight
delivery) in a timely manner designed to assure that such notice is in DTC's
possession no later than the close of business on the business day before the
Publication Date.  The Issuer or the Transfer Agent and Registrar will forward
such notice either in a separate secure transmission for each CUSIP number or in
a secure transmission of multiple CUSIP numbers (if applicable) that includes a
manifest or list of each CUSIP number submitted in that transmission. (The party
sending such notice shall have a method to verify subsequently the use of such
means and the timeliness of such notice.) The Publication Date shall be not less
than 30 calendar days nor more than 60 calendar days prior to the payment of any
such distribution or any such offering or issuance of rights with respect to the
Trust Preferred Securities.  After establishing the amount of payment to be made
on the Trust Preferred Securities, the Issuer or the Transfer Agent and
Registrar will notify DTC's Dividend Department of such payment 5 business days
prior to payment date.  Notices to

Registrar to DTC not less than 30 calendar days prior to such event by a secure
means in the manner set forth in paragraph 4.  Such redemption notice shall be

notice specifying the terms of the tender and the Publication Date of such
notice shall be sent by the Issuer or the Transfer Agent and Registrar to DTC by

to DTC's Reorganization Department at (212) 709-1093 or (212) 709-1094 and
receipt of such notice shall be confirmed by telephoning (212) 709-6884, or by

            New York, New York 10004-2695 

     9. DTC may by prior written notice direct the Issuer and the Transfer Agent
and Registrar to use any other telecopy number or address of DTC as the number
or address to which notices or payments may be sent.

     10. In the event of a conversion, redemption, or any other similar
transaction (e.g., tender made and accepted in response to the Issuer's or the
Transfer Agent and Registrar's invitation) necessitating a reduction in the
aggregate number of Trust Preferred Securities outstanding evidenced by Global
Certificates, DTC, in its discretion: (a) may request the Issuer or the Transfer
Agent and Registrar to issue and countersign a new Global Certificate; or (b)
may make an appropriate notation on the Global Certificate indicating the date
and amount of such reduction.

     11. DTC may discontinue its services as a securities depositary with
respect to the Trust Preferred Securities at any time by giving at least 90
days' prior written notice to the Issuer and the Transfer Agent and Registrar
(at which time DTC will confirm with the Issuer or the Transfer Agent and
Registrar the aggregate number of Trust Preferred Securities deposited with it)
and discharging its responsibilities with respect thereto under applicable law.
Under such circumstances, the Issuer may determine to make alternative
arrangements for book-entry settlement for the Trust Preferred Securities, make
available one or more separate global certificates evidencing Trust Preferred
Securities to any Participant having Trust Preferred Securities credited to its
DTC account, or issue definitive Trust Preferred Securities to the beneficial
holders thereof, and in any such case, DTC agrees to cooperate fully with the
Issuer and the Transfer Agent and Registrar, and to return the Global
Certificate, duly endorsed for transfer as directed by the Issuer or the
Transfer Agent and Registrar, together with any other documents of transfer
reasonably requested by the Issuer or the Transfer Agent and Registrar.

     12. In the event that the Issuer determines that beneficial owners of Trust
Preferred Securities shall be able to obtain definitive Trust Preferred
Securities, the Issuer or the Transfer Agent and Registrar shall notify DTC of
the availability of certificates.  In such event, the Issuer or the Transfer
Agent and Registrar shall issue, transfer and exchange certificates in
appropriate amounts, as required by DTC and others, and DTC agrees to cooperate
fully with the Issuer and the Transfer Agent and Registrar and to return the
Global Certificate, duly endorsed for transfer as directed by the Issuer or the
Transfer Agent and Registrar, together with any other documents of transfer
reasonably requested by the Issuer or the Transfer Agent and Registrar.

     13. This letter may be executed in any number of counterparts, each of
which when so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same instrument.

to advance funds on behalf of GBB Capital I.

any Person except to a Holder exercising his or her rights pursuant to Section
5.4(iv) or to a Successor Guarantee Trustee on acceptance by such Successor
Guarantee Trustee of its appointment to act as Successor Guarantee Trustee. The
right, title and interest of the Guarantee Trustee shall automatically vest in

undertake to perform only such duties as are specifically set forth in this
Guarantee Agreement, and no implied covenants shall be read into this Guarantee
Agreement against the Guarantee Trustee. In case an Event of Default has
occurred (that has not been cured or waived pursuant to Section 2.6), the
Guarantee Trustee shall exercise such of the rights and powers vested in it by
this Guarantee Agreement, and use the same degree of care and skill in its
exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

     (d)  No provision of this Guarantee Agreement shall be construed to relieve
the Guarantee Trustee from liability for its own negligent action, its own
negligent failure to act or its own willful misconduct, except that:

          (i)   prior to the occurrence of any Event of Default and after the
      curing or waiving of all such Events of Default that may have occurred:

                (A)  the duties and obligations of the Guarantee Trustee shall
          be determined solely by the express provisions of this Guarantee
          Agreement, and the Guarantee Trustee shall not be liable except for
          the performance of such duties and obligations as are specifically set
          forth in this Guarantee Agreement; and

                (B)  in the absence of bad faith on the part of the Guarantee
          Trustee, the Guarantee Trustee may conclusively rely, as to the truth
          of the statements and the correctness of the opinions expressed
          therein, upon any certificates or opinions furnished to the Guarantee
          Trustee and conforming to the requirements of this Guarantee
          Agreement; but in the case of any such certificates or opinions that
          by any provision hereof or of the Trust Indenture Act are specifically
          required to be furnished to the Guarantee Trustee, the Guarantee
          Trustee shall be under a duty to examine the same to determine whether
          or not they conform to the requirements of this Guarantee Agreement;

                                      -5-
<PAGE>
 
     (ii)  the Guarantee Trustee shall not be liable for any error of judgment
made in good faith by a Responsible Officer of the Guarantee Trustee, unless it
shall be proved that the Guarantee Trustee was negligent in ascertaining the
pertinent facts upon which such judgment was made;

     (iii) the Guarantee Trustee shall not be liable with respect to any action
taken or omitted to be taken by it in good faith in accordance with the
direction of the Holders of not less than a Majority in Liquidation Amount of
the Preferred Securities relating to the time, method and place of conducting
any proceeding for any remedy available to the Guarantee Trustee, or exercising
any trust or power conferred upon the Guarantee Trustee under this Guarantee
Agreement; and

     (iv)  no provision of this Guarantee Agreement shall require the Guarantee
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if the Guarantee Trustee shall have reasonable grounds for
believing that the repayment of such funds or liability is not reasonably
assured to it under the terms of this Guarantee Agreement or adequate indemnity
against such risk or liability is not reasonably assured to it.

     SECTION 3.2.  Certain Rights of Guarantee Trustee.

(a)  Subject to the provisions of Section 3.1:

     (i)   The Guarantee Trustee may rely and shall be fully protected in acting

reasonably believed by it to be genuine and to have been signed, sent or

absence of bad faith on its part, request and rely upon an Officers' Certificate

advice or opinion of such legal counsel with respect to legal matters shall be
full and complete authorization and protection in respect of any action taken,
suffered or omitted to be taken by it hereunder in good faith and in accordance
with such advice or opinion. Such legal counsel may be legal counsel to the
Guarantor or any of its Affiliates and may be one of its employees. The
Guarantee Trustee shall have the right at any time to seek instructions
concerning the administration of this Guarantee Agreement from any court of
competent jurisdiction.

     (v)   The Guarantee Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Guarantee Agreement at the request or
direction of any Holder, unless such Holder shall have provided to the Guarantee
Trustee such adequate security and 

                                      -6-

indemnity as would satisfy a reasonable person in the position of the Guarantee
Trustee, against the costs, expenses (including attorneys' fees and expenses)
and liabilities that might be incurred by it in complying with such request or
direction, including such reasonable advances as may be requested by the
Guarantee Trustee; provided that, nothing contained in this Section 3.2(a)(v)
shall be taken to relieve the Guarantee Trustee, upon the occurrence of an Event
of Default, of its obligation to exercise the rights and powers vested in it by
this Guarantee Agreement.

     (vi)   The Guarantee Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond,
debenture, note, other evidence of indebtedness or other paper or document, but
the Guarantee Trustee, in its discretion, may make such further inquiry or
investigation into such facts or matters as it may see fit.

     (vii)  The Guarantee Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through its
agents or attorneys, and the Guarantee Trustee shall not be responsible for any
misconduct or negligence on the part of any such agent or attorney appointed

     (viii) Whenever in the administration of this Guarantee Agreement the
Guarantee Trustee shall deem it desirable to receive instructions with respect
to enforcing any remedy or right or taking any other action hereunder, the
Guarantee Trustee (A) may request instructions from the Holders, (B) may refrain
from enforcing such remedy or right or taking such other action until such
instructions are received, and (C) shall be protected in acting in accordance
with such instructions.

    (b) No provision of this Guarantee Agreement shall be deemed to impose any
duty or obligation on the Guarantee Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it in any
jurisdiction in which it shall be illegal, or in which the Guarantee Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Guarantee Trustee
shall be construed to be a duty to act in accordance with such power and
authority.

     SECTION 3.3.  Indemnity.

     The Guarantor agrees to indemnify the Guarantee Trustee for, and to hold it
harmless against, any loss, liability or expense incurred without negligence or
bad faith on the part of the Guarantee Trustee, arising out of or in connection
with the acceptance or administration of this Guarantee Agreement, including the
costs and expenses of defending itself against any claim or liability in
connection with the exercise or performance of any of its powers or duties

     SECTION 5.1.  Guarantee.

     The Guarantor irrevocably and unconditionally agrees to pay in full on a

(except to the extent required by mandatory provisions of law) be entitled to
enforce or exercise any rights which it may acquire by way of subrogation or any
indemnity, reimbursement or other agreement, in all cases as a result of payment
under this Guarantee, if, at the time of any such payment, any amounts are due
and unpaid under this Guarantee.  If any amount shall be paid to the Guarantor
in violation of the preceding sentence, the Guarantor agrees to hold such amount
in trust for the Holders and to pay over such amount to the Holders.

year thereafter, Employee Resigns for Good Reason, upon the happening of one or
more of the following events (unless such event or occurrence is applied

Employee's assignment to any duties substantially inconsistent with Employee's
position, duties, responsibilities and status with Employer immediately prior to
a Change in Control, or any removal of Employee from any such position to a
position substantially inferior to such prior position;

                 5.4.1.2   A reduction by Employer of Employee's Salary or of
any bonus compensation formula applicable to Employee as in effect prior to a 
Change in Control;

                 5.4.1.3   A failure by Employer to maintain any of the 
employee benefits to which Employee was entitled prior to a Change in Control at
a level substantially similar to or greater than that in effect prior to a
Change in Control, through the continuation of the same or substantially similar
plans, programs and policies;

                 5.4.1.4   The failure by Employer to provide Employee with
the same number of paid vacation days and leave to which Employee would be
entitled as salaried employee of Employer, or any parent or successor of
Employer;

                 5.4.1.5   Employer requiring Employee to travel on 
employer's business to an extent substantially greater than Employee's present 
business travel obligations; or the relocation of Employee's office at least 
sixty (60) miles from its current location, without Employee's consent; and

of this Agreement by any successor of Employer as contemplated in section 10.2 
below.

constitute Good Reason.

owners (with right of survival) with the Bank of the annual increase of the cash
surrender value of the policy thereafter arising; however, the Employee's (and 
Employee's spouse's) right to draw against such increase (such draw to reduce 
eventual death benefits) shall never exceed $55,000 per 12-month period (the 
"Retirement Draw Benefit"). The shared right to ownership of this increase shall
continue for the lifetime of the Employee and the lifetime of the Employee's 
surviving spouse, but in no event longer than 40 years.

          6.1.1  The Retirement Draw Benefit will be made available by means of 
a split-dollar insurance policy which is to be purchased by the Bank within 
thirty (30) days of the date of this Agreement, and for which the premium 
payment split between the Bank and Employee and the payment terms are outlined 
in Exhibit B to this Agreement.

          6.1.2  Subject to the provisions of section 6.1.3 and 6.1.4 herein, 
Employee's right to the Retirement Draw Benefit shall not fully vest unless he
has been employed by Employer for seven (7) years from the Effective Date. If
Employee's employment with Employer ends any time before a date one (1) year 
from the date of this Agreement (the "Anniversary Date"), Employee will not have
any right to, or interest in, the Retirement Draw Benefit. If Employee's 
employment ends at any time after the Anniversary Date, but prior to the seven 
(7) year date of full vesting, Employee's right to one-seventh (1/7) of the 
Retirement Draw Benefit-i.e., the right to draw $7,143, or one-seventh of 
$50,000, per 12-month period-will vest on the Anniversary Date, and Employee's 
right to the Retirement Draw Benefit will continue to proportionately vest 
thereafter on a monthly basis, on the first date of each month following the 
Anniversary Date, until employment ends.

          6.1.3  Subject to the provisions of section 6.1.2 herein, if prior to 
a Change in Control and during the Term hereof, Employee is Terminated for any 
reason other than Disability, the vesting of Employee's right to the Retirement 
Draw Benefit will cease as of the date of termination. If prior to a Change of 
Control and during the Term hereof, Employee is Terminated by reason of 
Disability, the vesting of Employees's right to the Retirement Draw Benefit will
cease as of the date of termination unless the Board in its sole and absolute 
discretion approves additional vesting.

          6.1.4  Notwithstanding the provisions of section 6.1.2 herein, if
after a Change in Control and during the Term hereof, Employee is Terminated, or
Resigns for Good Reason, as provided in section 5.4.1 herein, Employee's right
to the Retirement Draw Benefit shall immediately vest in full, and such benefit
shall become available to Employee when Employee reaches Retirement Age.

under this Agreement all federal, state, city or other taxes or deductions as 
shall be required pursuant to any law, governmental regulation or ruling.

8.   ARBITRATION
     -----------

     8.1  Any controversy between the parties hereto, including the 
construction, application or breach of any of the terms, covenants or conditions
of this Agreement, and all claims relating to or arising from Employee's 
employment or Termination, including all statutory claims (including but not 
limited to all statutes dealing with employment discrimination), shall on a 
timely written request of one party served upon the other, be submitted to 
arbitration and be governed by the California Arbitration Act as set forth in 
the California Code of Civil Procedure (presently sections 1280 et seq.). The 
                                                                -- ---
parties agree that any written request for arbitration must be made within one 
year after the initiating party first learned or should have learned in the 
exercise of reasonable diligence of the essential facts upon which the claim is 
based, or first suffered any harm, or first learned or should have learned in 
the exercise of reasonable diligence of the breach of this Agreement, whichever 
is earlier. Any claim not raised within such time limitation shall be waived and
forever barred. The arbitration shall take place in Santa Clara County, 
California.

     8.2  The parties may agree upon one arbitrator, but in the event they 
cannot agree, there shall be three (3), one named in writing by each of the 
parties within ten (10) days after demand for arbitration is given, and a third 
chosen by the two so appointed; provided further that if the two appointed 
cannot agree on the choice, then application shall be made to a presiding judge 
of the Santa Clara County Superior Court for the purpose of designating a third 
arbitrator. The applying party (who may suggest in such application the names of
a suitable third arbitrator) shall provide the other party at least 48 hours 
prior notice of the application so that such other party may have the 
opportunity to submit one or more names of persons suitable to serve as the 
designated third arbitrator. The presiding judge shall have discretion to 
designate the third arbitrator from among the names suggested by either party or
from among any other persons such judge deems appropriate. The cost of such 
arbitration, including reasonable attorneys' fees, shall be borne by the losing 
party or in such proportions as the arbitrator(s) shall decide. Arbitration 
shall be the exclusive remedy of the parties and the award of the arbitrator(s) 
shall be final and binding upon the parties.

     IF BONUS COMPENSATION IS                     PAYMENT/OFFSET IS
- --------------------------------------------------------------------------------
        0 to $20,000                                         0
- --------------------------------------------------------------------------------

                                                                  April 28, 1995


          1.   Obligation. Ken Brenner, an individual ("Maker") who is currently
               ----------
an executive employee of Cupertino National Bank & Trust (the "Bank"), for value
received, hereby promises to pay to the Bank at 20230 Stevens Creek Boulevard, 
Cupertino, California 95014, the principal amount of two hundred sixteen 
thousand, three hundred fifty-five dollars ($216,355). This Note is delivered by
Maker in payment of Marker's share of a life insurance premium for life
insurance being purchased by the Bank (the "Life Insurance") pursuant to that
certain Severance and Retirement Benefits Agreement between Maker and Bank dated
April 28, 1995 (the "Benefits Agreement"). The terms of the Benefits Agreement
are incorporated herein by this reference. Caplitalized terms used herein
without definition shall have the meanings assigned to them in the Benefits
Agreement.

          2.   Interest Rate. This Note shall bear simple interest from and 
               -------------
after the date Maker reaches Retirement Age at an annual interest rate of eight 
percent (8%). In the event this Note is not paid pursuant to the terms of 
Section 3 below, any late payments shall bear interest until fully paid at an 
annual rate of five (5) points above the Bank's prime rate--which shall be 
defined as the then prevailing rate charged by the Bank for commercial borrowers
of highest credit quality.

          3.   Payment Schedule. Maker agrees to make payments on this Note 
               ----------------
annually out of incentive or bonus compensation, if any, earned by Maker under 
any Bank plan for such compensation, and hereby authorizes Bank to obtain such 
payments from Maker annually by deducting from incentive or bonus compensation 
(at such time as such compensation would otherwise be paid to Maker) in 
accordance with the following schedule:

================================================================================
     IF BONUS COMPENSATION IS                     PAYMENT APPLIED TO NOTE IS
- --------------------------------------------------------------------------------
           0 to $20,000                                      0
- --------------------------------------------------------------------------------
        $20,001 to $40,000                                 $5,000
- --------------------------------------------------------------------------------
        $40,001 to $60,000                                 $8,000
- --------------------------------------------------------------------------------
        $60,001 to $80,000                                $12,000
- --------------------------------------------------------------------------------
      greater than $80,000                                $16,000
================================================================================
<PAGE>
 
          If Maker ceases to be employed by Bank before Retirement Age, such 
that incentive or bonus compensation is no longer earned by Maker under any 
Bank plan, Maker shall have no obligation to make further payments on this Note 
until the death benefit provision is implemented.

          Maker further agrees that the balance of this Note, if any, unpaid at 
Maker's death shall be due and payable upon such death, and Maker hereby 
authorizes Bank to obtain from Maker the payoff of such unpaid balance by 
applying the death benefit proceeds under the Life Insurance. To the extent such
death benefit proceeds are insufficient to pay in full the unpaid balance of 
this Note, any remaining balance after application of the entire death benefit 
proceeds shall be deemed extinguished and no longer an obligation of Maker or 
Maker's estate.

          All payments received shall be applied first to interest, if any, then
accrued, and then to principal.

          4.   Prepayments; Application. This Note may be prepaid in whole or in
               ------------------------
part any time without penalty or premium.

          5.   Events of Default. There shall be an "Event of Default" under 
               -----------------
this Note if Maker shall fail to make a payment to Bank when due and such 
default shall continue for thirty (30) days after Bank provides written notice 
to Maker of such default.

          6.   Remedies. If an Event of Default shall occur, any indebtedness of
               --------
Maker under this Note shall, at Bank's option and without notice, become 
immediately due and payable without presentment, demand, protest or notice of 
dishonor, all of which are hereby expressly waived by Maker; and Holder shall 
have all of the rights, powers and remedies available under this Note, all of 
which rights, powers and remedies may be exercised at any time by Bank and from 
time to time after the occurrence of an Event of Default. All of the rights, 
powers and remedies of Bank in connection with this Note are cumulative and not 
exclusive and shall be in addition to any other rights, powers or remedies 
provided by law or equity.

          7.   Costs of Collection. If this Note is not paid when due, whether 
               -------------------
at maturity or by acceleration, Maker promises to pay all costs incurred by the 
Bank collecting the amounts due hereunder, including reasonable attorney's fees.

          8.   Waiver. Presentment, demand, protest, notices of protest, 
               ------
dishonor and non-payment of this Note and all notices of every kind are hereby 
waived, except notices required by this Note. No single or partial exercise of 
or forbearance from exercising any power hereunder or under any guaranty 
pertaining to this Note shall preclude other or further exercises thereof or the
exercise of any other power.

          9.   Special Principal/Interest Reduction. Maker and Holder agree that
               ------------------------------------
if Maker ceases to be employed by Bank on or before November 1, 2001, under 
circumstances where Maker is not, under the terms of the Benefits Agreement, 
fully vested with respect to the Retirement Draw Benefit, there shall be at the 
time of Maker's

                                      -2-

<PAGE>
 
cessation of employment a one-time reduction of principal and interest (if any) 
owed by Maker hereunder to reflect the unvested portion of the Retirement Draw 
Benefit which will be foregone by Maker as a result of ceasing employment 
before full vesting. By way of example only, if Maker ceases employment when he
is vested with respect to one-seventh of the Retirement Draw Benefit and
unvested with respect to six-sevenths, there shall be a one-time reduction of
sex-sevenths of the principal of this Note; all other terms and conditions shall
remain in effect with respect to payment of the balance.

          10.  Form of Payment; Governing Law.  Principal is payable in lawful
               ------------------------------

Reason (as defined in section 5.4.1) or death of Employee, whichever occurs

employment between Employee and Employer, nor shall this Agreement alter
Employer's personnel policies and practices, including the right to terminate
Employee at any time with or without cause.

     3.2    Notwithstanding the right of Bank to terminate Employee, any such

          -------------
initial grant of options to acquire 15,000 shares of Corporation common stock.

merger into Comerica Bank, then the Bank will reimburse Employee for the fair

rights subsequent to the Bank's payment to employee, he will be required to
reimburse the Bank the payment amount.

     4.9  COMPENSATION FREEZE.  Subject to the terms and conditions herein, and

for a period for three (3) years from the Effective Date, Employee's total

promotion of Employee to a new position or title; however, other than the cost-
of-living increase to Salary as provided for herein, nothing in this Agreement
shall

                                       5
<PAGE>
 
suggest or imply that the Board is under any duty or obligation to increase
Employee's Salary or other compensation or standard employee benefits at any
time during the three (3) year period following the Effective Date. Employee's
current salary, his current participation in incentive compensation programs of
the Employer and a description of current standard employee benefits are set
forth above.

5.   TERMINATION OF EMPLOYMENT
     -------------------------

     5.1    The provisions of this section 5 shall govern the benefits, if any,
which Employee shall receive upon Termination of his Employment.

     5.2    BENEFITS UPON VOLUNTARY TERMINATION.  In the event that Employee
            -----------------------------------
voluntarily resigns from his employment with the Bank, or in the event that his
employment terminates as a result of his death or disability, Employee shall be
entitled to no compensation or benefits from the Bank other than those earned
under paragraph 4 above through the date of his termination.

     5.3    BENEFITS UPON OTHER TERMINATION.  Employee agrees that his
            -------------------------------
employment may be terminated by the Bank at any time, with or without cause. In
the event of the termination of Employee's employment by the Bank for the
reasons set forth below, he shall be entitled to the following:

            5.3.1  TERMINATION FOR PERSONAL CONDUCT/CAUSE.  The payments
                   --------------------------------------
set forth in section 5.3.2 hereof shall not apply if at any time Employee is
terminated upon a good faith finding of Personal Conduct/Cause by the Board;
provided, however, that Employee shall be given written notice of the Board's
finding of conduct by Employee amounting to Personal Conduct/Cause for such
Termination. Such notice shall be accompanied by a copy of a resolution duly
adopted by the affirmative vote of not less than a majority of the members of
the Board adopted at a duly-noticed meeting of the Board, and finding in good
faith that Employee engaged in conduct amounting to Personal Conduct/Cause and
specifying the particulars thereof.

            5.3.2  If the Employee is Terminated for Performance/Cause or
other than by reason of death, Retirement, Disability or Personal Conduct/Cause,
as set forth herein, or if Employee Resigns for Good Reason, as defined in
section 5.4.1 below, the Bank shall pay to Employee twelve (12) months' Salary
("Severance Payment") at a rate equivalent to the then-current Salary of
Employee.

            5.3.3  The Bank shall have the option of paying Severance
Payments in a lump-sum payment, or by salary continuation payments made under
the Bank's normal

                                       6
<PAGE>
 
employee compensation schedule. If the Bank chooses the lump-sum payment option,
such payment shall be made not later than the tenth (10th) day following the
date of cessation of employment, Termination or Resignation for Good Reason.

            5.3.4  Although a payment triggering such section is not intended
hereby, amounts otherwise due under this section will be reduced if, and to the
extent that, such reduction will increase the net amount Employee will receive
under this Agreement after taking into account the imposition of the excise tax
under section 4999 of the Internal Revenue Code, if applicable.

     5.4    If a Change in Control occurs during the Term of this Agreement,
Employee may thereafter be entitled to a payment set forth in section 5.3.2 in
accordance with the terms hereof, subject to the following limitations:

            5.4.1  RESIGNATION FOR GOOD REASON. The payments set forth in
                   ---------------------------
section 5.3.2 hereof shall apply if, after a Change of Control but within one
year thereafter, Employee Resigns for Good Reason, upon the happening of one or
more of the following events (unless such event or occurrence is applied
generally to all officers and employees of Employer and any parent or successor
of any of them), any of which will constitute Good Reason for Employee's
Resignation:

            5.4.1.1  Without Employee's express written consent, Employee's
assignment to any duties substantially inconsistent with Employee's position,
duties, responsibilities and status with Employer immediately prior to a Change
in Control, or any removal of Employee from any such position to a position
substantially inferior to such prior position;

            5.4.1.2  A reduction by Employer of Employee's Salary or of any
bonus compensation formula applicable to Employee as in effect prior to a Change
in Control;

            5.4.1.3  A failure by Employer to maintain any of the employee
benefits to which Employee was entitled prior to a Change in Control at a level
substantially similar to or greater than that in effect prior to a Change in
Control, through the continuation of the same or substantially similar plans,
programs and policies;

            5.4.1.4  The failure by Employer to provide Employee with the same
number of paid vacation days and leave to which Employee would be entitled as
salaried employee of Employer, or any parent or successor of Employer;

                                       7
<PAGE>
 
                 5.4.1.5  Employer requiring Employee to travel on employer's
business to an extent substantially greater than Employee's present business
travel obligations; or the relocation of Employee's office at least sixty (60)
miles from its current location, without Employee's consent; and

                 5.4.1.6  The failure of the Bank to obtain the assumption of
this Agreement by any successor of Employer as contemplated in section 10.2
below.

          5.4.2  The events described above are the only events which shall
constitute Good Reason.

6.   CERTAIN RETIREMENT BENEFITS
     ---------------------------

     6.1  Subject to the special terms and conditions contained below, upon
cessation of Employee's employment with Employer, if the Employee has reached
the Retirement Age, or as soon thereafter as Employee reaches the Retirement
Age, the Bank hereby agrees that the Employee and Employee's spouse shall become
the joint owners (with right of survival) with the Bank of the annual increase
of the cash surrender value of the policy thereafter arising; however, the
Employee's (and Employee's spouse's) right to draw against such increase (such
draw to reduce eventual death benefits) shall never exceed $55,000 per 12-month
period (the "Retirement Draw Benefit"). The shared right to ownership of this
increase shall continue for the lifetime of the Employee and the lifetime of the
Employee's surviving spouse, but in no event longer than 40 years.

          6.1.1  The Retirement Draw Benefit will be made available by means of
a split-dollar insurance policy which is to be purchased by the Bank within
thirty (30) days of the date of this Agreement, and for which the premium
payment split between the Bank and Employee and the payment terms are outlined
in Exhibit B to this Agreement.

          6.1.2  Subject to the provisions of sections 6.1.3 and 6.1.4 herein,
Employee's right to the Retirement Draw Benefit shall not fully vest unless he
has been employed by Employer for seven (7) years from the Effective Date.  If
Employee's employment with Employer ends any time before a date one (1) year
from the date of this Agreement (the "Anniversary Date"), Employee will not have
any right to, or interest in, the Retirement Draw Benefit.  If Employee's
employment ends at any time after the Anniversary Date, but prior to the seven
(7) year date of full vesting, Employee's right to one-seventh (1/7) of the
Retirement Draw Benefit--i.e., the right to draw $7,857, or one-seventh of
$55,000, per 12-month period--will vest on the Anniversary Date, and Employee's
right to the Retirement Draw Benefit will continue to proportionately vest
thereafter on a monthly basis, on the first date of each month following the
Anniversary Date, until employment ends.

                                       8
<PAGE>
 
          6.1.3  Subject to the provisions of section 6.1.2 herein, if prior to
a Change in Control and during the Term hereof, Employee is Terminated for any
reason other than Disability, the vesting of Employee's right to the Retirement
Draw Benefit will cease as of the date of termination.  If prior to a Change of
Control and during the Term hereof, Employee is Terminated by reason of
Disability, the vesting of Employee's right to the Retirement Draw Benefit will
cease as of the date of termination unless the Board in its sole and absolute
discretion approves additional vesting.

          6.1.4  Notwithstanding the provisions of section 6.1.2 herein, if
after a Change in Control and during the Term hereof, Employee is Terminated, or
Resigns for Good Reason, as provided in section 5.4.1 herein, Employee's right
to the Retirement Draw Benefit shall immediately vest in full, and such benefit
shall become available to Employee when Employee reaches Retirement Age.

7.   FEDERAL INCOME TAX WITHHOLDING
     ------------------------------

     7.1  The Bank shall withhold from any compensation or benefits payable
under this Agreement all federal, state, city or other taxes or deductions as
shall be required pursuant to any law, governmental regulation or ruling.

8.   ARBITRATION
     -----------

     8.1  Any controversy between the parties hereto, including the
construction, application or breach of any of the terms, covenants or conditions
of this Agreement, and all claims relating to or arising from Employee's
employment or Termination, including all statutory claims (including but not
limited to all statutes dealing with employment discrimination), shall on a
timely written request of one party served upon the other, be submitted to
arbitration and be governed by the California Arbitration Act as set forth in
the California Code of Civil Procedure (presently sections 1280 et seq.). The
                                                                -- ---        
parties agree that any written request for arbitration must be made within one
year after the initiating party first learned or should have learned in the
exercise of reasonable diligence of the essential facts upon which the claim is
based, or first suffered any harm, or first learned or should have learned in
the exercise of reasonable diligence of the breach of this Agreement, whichever
is earlier.  Any claim not raised within such time limitation shall be waived
and forever barred.  The arbitration shall take place in Santa Clara County,
California.

     8.2  The parties may agree upon one arbitrator, but in the event they
cannot agree, there shall be three (3), one named in writing by each of the
parties within ten (10) days after demand for arbitration is given, and a third
chosen by the two so appointed;

                                       9
<PAGE>
 
provided further that if the two appointed cannot agree on the choice, then
application shall be made to a presiding judge of the Santa Clara County
Superior Court for the purpose of designating a third arbitrator. The applying
party (who may suggest in such application the names of a suitable third
arbitrator) shall provide the other party at least 48 hours prior notice of the
application so that such other party may have the opportunity to submit one or
more names of persons suitable to serve as the designated third arbitrator. The
presiding judge shall have discretion to designate the third arbitrator from
among the names suggested by either party or from among any other persons such
judge deems appropriate. The cost of such arbitration, including reasonable
attorneys' fees, shall be borne by the losing party or in such proportions as
the arbitrator(s) shall decide. Arbitration shall be the exclusive remedy of the
parties and the award of the arbitrator(s) shall be final and binding upon the
parties.

9.   GENERAL PROVISIONS

$218,386                                                   Cupertino, California
                                                                  April 14, 1995


          1.   Obligation. David Hood, an individual ("Maker") who is currently 
               ----------
an executive employee of Cupertino National Bank & Trust (the "Bank"), for value
received, hereby promises to pay to the Bank at 20230 Stevens Creek Boulevard, 
Cupertino, California 95014, the principal amount of two hundred eighteen 
thousand three hundred eight-six dollars ($218,386). This Note is delivered by 
Maker in payment of Marker's share of a life insurance premium for life 
insurance being purchased by the Bank (the "Life Insurance") pursuant to that 
certain Severance and Retirement Benefits Agreement between Maker and Bank dated
April 14, 1995 (the "Benefits Agreement"). The terms of the Benefits Agreement 
are incorporated herein by this reference. Capitalized terms used herein without
definition shall have the meanings assigned to them in the Benefits Agreement.

          2.   Interest Rate. This Note shall bear simple interest from and 
               -------------
after the date Maker reaches Retirement Age at an annual interest rate of eight 
percent (8%). In the event this Note is not paid pursuant to the terms of 
Section 3 below, any late payments shall bear interest until fully paid at an 
annual rate of five (5) points above the Bank's prime rate--which shall be 
defined as the then prevailing rate charged by the Bank for commercial borrowers
of highest credit quality.

          3.   Payment Schedule. Maker agrees to make payments on this Note 
               ----------------
annually out of incentive or bonus compensation, if any, earned by Maker under 
any Bank plan for such compensation, and hereby authorizes Bank to obtain such 
payments from Maker annually by deducting from incentive or bonus compensation 
(at such time as such compensation would otherwise be paid to Maker) in 
accordance with the following schedule:

================================================================================
     IF BONUS COMPENSATION IS                     PAYMENT APPLIED TO NOTE IS
- --------------------------------------------------------------------------------
          0 to $20,000                                        0
- --------------------------------------------------------------------------------
       $20,001 to $40,000                                  $5,000
- --------------------------------------------------------------------------------
       $40,001 to $60,000                                  $8,000
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
     greater than $80,000                                 $16,000
================================================================================
<PAGE>
 
          If Maker ceases to be employed by Bank before Retirement Age, such 
that incentive or bonus compensation is no longer earned by Maker under any Bank
plan, Maker shall have no obligation to make further payments on this Note until
the death benefit provision is implemented.

          Maker further agrees that the balance of this Note, if any, unpaid at 
Maker's death shall be due and payable upon such death, and Maker hereby 
authorizes Bank to obtain from Maker the payoff of such unpaid balance by 
applying the death benefit proceeds from under the Life Insurance. To the extent
such death benefit proceeds are insufficient to pay in full the unpaid balance 
of this Note, any remaining balance after application of the entire death 
benefit proceeds shall be deemed extinguished and no longer an obligation of 
Maker or Maker's estate.

          All payments received shall be applied first to interest, if any, then
accrued, and then to principal.

          4.   Prepayments; Application. This Note may be prepaid in whole or in
               ------------------------
part any time without penalty or premium.

          5.   Events of Default. There shall be an "Event of Default" under 
               -----------------
this Note if Maker shall fail to make a payment to Bank when due and such 
default shall continue for thirty (30) days after Bank provides written notice 
to Maker of such default.

          6.   Remedies. If an event of Default shall occur, any indebtedness of
               --------
Maker under this Note shall, at Bank's option and without notice, become 
immediately due and payable without presentment, demand, protest or notice of 
dishonor, all of which are hereby expressly waived by Maker; and Holder shall 
have all of the rights, powers and remedies available under this Note, all of 
which rights, powers and remedies may be exercised at any time by Bank and from 
time to time after the occurrence of an Event of Default. All of the rights, 
powers and remedies of Bank in connection with this Note are cumulative and not 
exclusive and shall be in addition to any other rights, powers or remedies 
provided by law or equity.

          7.   Costs of Collection. If this Note is not paid when due, whether 
               -------------------
at maturity or by acceleration, Maker promises to pay all costs incurred by the 
Bank collecting the amounts due hereunder, including reasonable attorneys' fees.

          8.   Waiver. Presentment, demand, protest, notices of protest, 
               ------
dishonor and non-payment of this Note and all notices of every kind are hereby 
waived, except notices required by this Note. No single or partial exercise of 
or forbearance from exercising any power hereunder or under any guaranty 
pertaining to this Note shall preclude other or further exercises thereof or the
exercise of any other power.

          9.   Special Principal/Interest Reduction. Maker and Holder agree that
               ------------------------------------
is Maker ceases to be employed by Bank on or before November 1, 2001, under 
circumstances where Maker is not, under the terms of the Benefits Agreement, 
fully vested with respect to the Retirement Draw Benefit, there shall be at the 
time of Maker's

                                      -2-
<PAGE>
 
cessation of employment a one-time reduction of principal and interest (if any) 
owed by Maker hereunder to reflect the unvested portion of the Retirement Draw 
Benefit which will be foregone by Maker as a result of ceasing employment before
full vesting. By way of example only, if Maker ceases employment when he 
is vested with respect to one-seventh of the Retirement Draw Benefit and 
unvested with respect to six-sevenths, there shall be a one-time reduction of 
six-sevenths of the principal of this Note; all other terms and conditions shall
remain in effect with respect to payment of the balance.

          10.  Form of Payment; Governing Law. Principal is payable in lawful 
               ------------------------------
money of the United States to the Bank. This Note has been executed and 
delivered by Maker in the State of California and shall be governed by and 
construed in accordance with the laws of the State of California.

shall continue until the Termination, Retirement, Resignation for Good Reason 
(as defined in section 5.4.1) or death of Employee, whichever occurs first. This
Agreement and all of its terms and conditions may be terminated upon written 
agreement by the parties. Notwithstanding the foregoing, nothing contained 
herein shall imply the existence of a contract or assurance of employment 
between Employee and Employer, nor shall this Agreement alter Employer's 
personnel policies and practices, including the right to terminate Employee at 
any time with or without cause.

     3.2  Notwithstanding the right of Bank to terminate Employee, any such 
Termination shall be governed by section 5 below.

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

     4.1  Salary. Employee shall be paid a monthly salary of $10,000.00

accordance with the Bank's normal payroll procedures.

     4.2. BENEFITS. Employee shall have the right, on the same basis as other

     4.4  STOCK OPTIONS. Upon joining the Bank, Employee will receive an initial
          -------------
grant of options to acquire 15,000 shares of Corporation common stock. The 
shares will vest under the provisions of the Bank's 1995 Stock Option Plan.

     4.5  PERFORMANCE BONUS. Employee will be eligible for a performance bonus

     4.8  In the event that Employee's acceptance of employment with the Bank at
this time causes Employee to lose stock option rights with University National 
Bank and Trust ("University") that he would have had if he remained employed by 
University through the consummation of the "second stage" of University's plan 
merger into Comerica Bank, then the Bank will reimburse Employee for the fair 
market value of such stock option rights less the exercise price of the stock 
calculated as of the closing date of University's "first stage" merger with 
Interim Comerica on or about April 3, 1995, in a total amount not to exceed 
$175,000. Such reimbursement for lost stock option rights shall be paid to 
employee in two equal installments, the first on February 28, 1996 and the 
second on February 28, 1997, provided that no such payment shall be due or made 
unless Employee is an officer or employee of the Bank at such time payment is to
be made. If Employee receives compensation for the loss of his stock option 
rights subsequent to the Bank's payment to employee, he will be required to 
reimburse the Bank the payment amount.

     4.9  COMPENSATION FREEZE. Subject to the terms and conditions herein, and 
          -------------------

Index for All Urban Consumers in the San Francisco, Oakland and Bay Area. In 
addition, it is within the complete discretion of the Employer to increase such 
amount of total compensation at any time and for any reason, including a 
promotion of Employee to a new position or title; however, other than the 
cost-of-living increase to Salary as provided for herein, nothing in this 
Agreement shall 

                                       5

<PAGE>
 
suggest or imply that the Board is under any duty or obligation to increase 
Employee's Salary or other compensation or standard employee benefits at any 
time during the three (3) year period following the Effective Date. Employee's 
current salary, his current participation in incentive compensation programs of 
the Employer and a description of current standard employee benefits are set 
forth above.

5.   TERMINATION OF EMPLOYMENT
     -------------------------
     
     5.1  The provisions of this section 5 shall govern the benefits, if any, 
which Employee shall receive upon Termination of his Employment.

     5.2  BENEFITS UPON VOLUNTARY TERMINATION.  In the event that Employee 
          -----------------------------------
voluntarily resigns from his employment with the Bank, or in the event that his 
employment terminates as a result of his death or disability, Employee shall be 
entitled to no compensation or benefits from the Bank other than those earned 
under paragraph 4 above through the date of his termination.

     5.3  BENEFITS UPON OTHER TERMINATION.  Employee agrees that his employment 
          -------------------------------
may be terminated by the Bank at any time, with or without cause. In the event 
of the termination of Employee's employment by the Bank for the reasons set 
forth below, he shall be entitled to the following:

          5.3.1  TERMINATION FOR PERSONAL CONDUCT/CAUSE.  The payments set 
                 --------------------------------------
forth in section 5.3.2 hereof shall not apply if at any time Employee is 
terminated upon a good faith finding of Personal Conduct/Cause by the Board; 
provided, however, that Employee shall be given written notice of the Board's 
finding of conduct by Employee amounting to Personal Conduct/Cause for such 
Termination. Such notice shall be accompanied by a copy of a resolution duly 
adopted by the affirmative vote of not less than a majority of the members of 
the Board adopted at a duly-noticed meeting of the Board, and finding in good 
faith that Employee engaged in conduct amounting to Personal Conduct/Cause and 
specifying the particulars thereof.

          5.3.2  If the Employee is Terminated for Performance/Class or
other than by reason of death, Retirement, Disability or Personal Conduct/Cause
as set forth herein, or if Employee Resigns for Good Reason, as defined in
section 5.4.1 below, the Bank shall pay to Employee twelve (12) months' Salary
("Severance Payment") at a rate equivalent to the then-current Salary of
Employee.

          5.3.3  The Bank shall have the option of paying Severance Payments in
a lump-sum payment, or by salary continuation payments made under the Bank's
normal

                                       6
<PAGE>
 
employee compensation schedule.  If the Bank chooses the lump-sum payment
option, such payment shall be made not later than the tenth (10th) day following
the date of cessation of employment, Termination or Resignation for Good Reason.

          5.3.4  Although a payment triggering such section is not intended
hereby, amounts otherwise due under this section will be reduced if, and to the
extent that, such reduction will increase the net amount Employee will receive
under this Agreement after taking into account the imposition of the excise tax
under section 4999 of the Internal Revenue Code, if applicable.

     5.4  If a Change in Control occurs during the Term of this Agreement,
Employee may thereafter be entitled to a payment set forth in section 5.3.2 in
accordance with the terms hereof, subject to the following limitations:

          5.4.1  RESIGNATION FOR GOOD REASON.  The payments set forth in section
                 ---------------------------                                    
5.3.2 hereof shall apply if, after a Change of Control but within one year
thereafter, Employee Resigns for Good Reason, upon the happening of one or more
of the following events (unless such event or occurrence is applied generally to
all officers and employees of Employer and any parent or successor of any of
them), any of which will constitute Good Reason for Employee's Resignation:

                 5.4.1.1  Without Employee's express written consent, Employee's
assignment to any duties substantially inconsistent with Employee's position,
duties, responsibilities and status with Employer immediately prior to a Change
in Control, or any removal of Employee from any such position to a position
substantially inferior to such prior position;

                 5.4.1.2  A reduction by Employer of Employee's Salary or of any
bonus compensation formula applicable to Employee as in effect prior to a Change
in Control;

                 5.4.1.3  A failure by Employer to maintain any of the employee
benefits to which Employee was entitled prior to a Change in Control at a level
substantially similar to or greater than that in effect prior to a Change in
Control, through the continuation of the same or substantially similar plans,
programs and policies;

                 5.4.1.4  The failure by Employer to provide Employee with the
same number of paid vacation days and leave to which Employee would be entitled
as salaried employee of Employer, or any parent or successor of Employer;

                                       7
<PAGE>
 
                 5.4.1.5  Employer requiring Employee to travel on employer's
business to an extent substantially greater than Employee's present business
travel obligations; or the relocation of Employee's office at least sixty (60)
miles from its current location, without Employee's consent; and

                 5.4.1.6  The failure of the Bank to obtain the assumption of
this Agreement by any successor of Employer as contemplated in section 10.2
below.

          5.4.2  The events described above are the only events which shall
constitute Good Reason.

6.   CERTAIN RETIREMENT BENEFITS
     ---------------------------

     6.1  Subject to the special terms and conditions contained below, upon
cessation of Employee's employment with Employer, if the Employee has reached
the Retirement Age, or as soon thereafter as Employee reaches the Retirement
Age, the Bank hereby agrees that the Employee and Employee's spouse shall become
the joint owners (with right of survival) with the Bank of the annual increase
of the cash surrender value of the policy thereafter arising; however, the
Employee's (and Employee's spouse's) right to draw against such increase (such
draw to reduce eventual death benefits) shall never exceed $55,000 per 12-month
period (the "Retirement Draw Benefit"). The shared right to ownership of this
increase shall continue for the lifetime of the Employee and the lifetime of the
Employee's surviving spouse, but in no event longer than 40 years.

          6.1.1 The Retirement Draw Benefit will be made available by means of
a split-dollar insurance policy which is to be purchased by the Bank within
thirty (30) days of the date of this Agreement, and for which the premium
payment split between the Bank and Employee and the payment terms are outlined
in Exhibit B to this Agreement.

         6.1.2  Subject to the provisions of sections 6.1.3 and 6.1.4
herein, Employee's right to the Retirement Draw Benefit shall not fully vest
unless he has been employed by Employer for seven (7) years from the Effective
Date. If Employee's employment with Employer ends any time before a date one (1)
year from the date of this Agreement (the "Anniversary Date"), Employee will not
have any right to, or interest in, the Retirement Draw Benefit. If Employee's
employment ends at any time after the Anniversary Date, but prior to the seven
(7) year date of full vesting, Employee's right to one-seventh (1/7) of the
Retirement Draw Benefit--i.e., the right to draw $6,285, or one-seventh of
$44,000, per 12-month period--will vest on the Anniversary Date, and Employee's
right to the Retirement Draw Benefit will continue to proportionately vest
thereafter on a monthly basis, on the first date of each month following the
Anniversary Date, until employment ends.

                                       8
<PAGE>
 
          6.1.3  Subject to the provisions of section 6.1.2 herein, if prior to
a Change in Control and during the Term hereof, Employee is Terminated for any
reason other than Disability, the vesting of Employee's right to the Retirement
Draw Benefit will cease as of the date of termination. If prior to a change of
Control and during the Term hereof, Employee is Terminated by reason of
Disability, the vesting of Employee's right to the Retirement Draw Benefit will
cease as of the date of termination unless the Board in its sole and absolute
discretion approves additional vesting.

          6.1.4  Notwithstanding the provisions of Section 6.1.2 herein, if
after a Change in Control and during the Term hereof, Employee is Terminated, or
Resigns for Good Reason, as provided in section 5.4.1 herein, Employee's right
to the Retirement Draw Benefit shall immediately vest in full, and such benefit
shall become available to Employee when Employee reaches Retirement Age.

7.   FEDERAL INCOME TAX WITHHOLDING
     ------------------------------

     7.1  The Bank shall withhold from any compensation or benefits payable 
under this Agreement all federal, state, city or other taxes or deductions as 
shall be required pursuant to any law, governmental regulation or ruling.

8.   ARBITRATION
     -----------

     8.1  Any controversy between the parties hereto, including the 
construction, application or breach of any of the terms, covenants or conditions
of this Agreement, and all claims relating to or arising from Employee's
employment or Termination, including all statutory claims (including but not
limited to all statutes dealing with employment discrimination), shall on a
timely written request of one party served upon the other, be submitted to
arbitration and be governed by the California Arbitration Act as set forth in
the California Code of Civil Procedure (presently sections 1280 et seq.). The
                                                                -- ---
parties agree that any written request for arbitration must be made within one
year after the initiating party first learned or should have learned in the
exercise of reasonable diligence of the essential facts upon which the claim is
based, of first suffered any harm, or first learned or should have learned in
the exercise of reasonable diligence of the breach of this Agreement, whichever
is earlier. Any claim not raised within such time limitation shall be waived and
forever barred. The arbitration shall take place in Santa Clara County,
California.

     8.2  The parties may agree upon one arbitrator, but in the event they
cannot agree, there shall be three (3), one named in writing by each of the
parties within ten (10) days after demand for arbitration is given, and a third
chosen by the two so appointed;


<PAGE>
 
provided further that if the two appointed cannot agree on the choice, then
application shall be made to a presiding judge of the Santa Clara County
Superior Court for the purpose of designating a third arbitrator. The applying
party (who may suggest in such application the names of a suitable third
arbitrator) shall provide the other party at least 48 hours prior notice of the
application so that such other party may have the opportunity to submit one or
more names of persons suitable to serve as the designated third arbitrator. The
presiding judge shall have discretion to designate the third arbitrator from
among the names suggested by either party or from among any other persons such
judge deems appropriate. The cost of such arbitration, including reasonable
attorneys' fees, shall be borne by the losing party or in such proportions as
the arbitrator(s) shall decide. Arbitration shall be the exclusive remedy of the
parties and the award of the arbitrator(s) shall be final and binding upon the
parties.

                          EMPLOYMENT, SEVERANCE AND 
                         RETIREMENT BENEFITS AGREEMENT


     THIS EMPLOYMENT, SEVERANCE AND RETIREMENT BENEFITS AGREEMENT (the 
"Agreement") is made and entered on this 31st day of July, 1995 and is effective
as of September 1, 1994, by and between CUPERTINO NATIONAL BANCORP (the
"Corporation"), its wholly owned subsidiary CUPERTINO NATIONAL BANK & TRUST (the
"Bank") and STEVEN C. SMITH ("Employee").

    
     The Corporation, Bank and Employee agree as follows:

1.   DEFINITIONS
     ----------- 

     1.1  "Agreement" means only the agreement contained in this document and as
modified in writing pursuant to section 10.5 herein.

     1.2  "Anniversary Date" means the date one (1) year from the Effective 
Date.

     1.3  "Bank" means Cupertino National Bank & Trust, and any successor to its
business or assets which executes and delivers the Agreement as provided by 
section 10.2 herein or which becomes bound by this Agreement by operation of 
law.

     1.4  "Board" means the Board of Directors of the Bank.

     1.5  "Cause" means (1) Employees acts of personal dishonesty; willful  
misconduct; breach of fiduciary duty or violation of banking law involving an 
intent to obtain personal or family profit; willful violation of any law, rule, 
or regulation which results in action against or restrictions imposed on the 
Bank by regulatory authorities; habitual abuse of substances (as corroborated by
a physician) or extended unexcused absence from work; or (2) Employee's
continued failure to substantially perform Employee's duties (which failure may
be determined by the Board by reference to the quality of the Company's
financial condition or operating performance) with the Bank (other than any
failure resulting from Disability) after a written demand for substantial
performance is given to Employee by the Board which demand specifically
identifies the manner in which the Board believes that Employee has not
substantially performed Employee's duties. The definition of "Cause" as set
forth in subsection (1) hereof is sometimes referred to separately herein as
"Personal Conduct/ Cause," and the definition of "Cause" as set forth in
subsection (2) is sometimes referred to separately herein as
"Performance/Cause." The term "Cause," standing alone, shall mean either
Personal Conduct/Cause or Performance/Cause or both. For purposes of the
definition of Personal Conduct/Cause, an act, or failure to act, on the
Employee's part shall be




     
<PAGE>
 
considered "willful" only if done, or omitted to be done, by him without 
reasonable belief that such act, or failure to act, is in the best interests of 
the Employer.

     1.6  "Change in Control" means a change in the Board of Directors, or the 
Corporation or the Bank following: 
     
          1.6.1 The acquisition, directly or indirectly, of more than 25% of the
outstanding shares of any class of voting securities of the Corporation of the 
Bank by any Person; or

          1.6.2 A merger, consolidated or sale of all or substantially all of 
the assets of the Corporation or the Bank, such that the individuals 
constituting the Corporation Board or the Board of the Bank immediately prior to
such period shall cease to constitute a majority of such Board, unless the
election of each director who was not a director prior thereto was approved by
vote of at least two-thirds of the directors then in office who were directors
prior to such period.

          1.6.3 Notwithstanding the foregoing, any change in the Board of either
the Corporation or the Bank which occurs within the twenty-four (24) month

<PAGE>
 
     5.3  BENEFITS UPON OTHER TERMINATION. Employee agrees that his employment
          -------------------------------
may be terminated by the Bank at any time, with or without cause. In the event
of the termination of Employee's employment by the Bank for the reasons set
forth below, he shall be entitled to the following:

          5.3.1  TERMINATION FOR PERSONAL CONDUCT/CAUSE. The payments set
                 --------------------------------------
forth in section 5.3.2 hereof shall not apply if at any time Employee is
terminated upon a good faith finding of Personal Conduct/Cause by the Board;
provided, however, that Employee shall be given written notice of the Board's
finding of conduct by Employee amounting to Personal Conduct/Cause for such
Termination. Such notice shall be accompanied by a copy of a resolution duly
adopted by the affirmative vote of not less than a majority of the members of
the Board adopted at a duly-noticed meeting of the Board, and finding in good
faith that Employee engaged in conduct amounting to Personal Conduct/Cause and
specifying the particulars thereof.

          5.3.2  If the Employee is Terminated for Performance/Cause or
other than by reason of death, Retirement, Disability or Personal Conduct/Cause,
as set forth herein, or if Employee Resigns for Good Reason, as defined in

("Severance Payment") at a rate equivalent to the then-current Salary of
Employee.

          5.3.3  The Bank shall have the option of paying Severance Payments
in a lump-sum payment, or by salary continuation payments made under the Bank's
normal employee compensation schedule. If the Bank chooses the lump-sum payment
option, such payment shall be made not later than the tenth (10th) day following
the date of cessation of employment, Termination or Resignation for Good Reason.

          5.3.4  Although a payment triggering such section is not intended
hereby, amounts otherwise due under this section will be reduced if, and to the
extent that, such reduction will increase the net amount Employee will receive
under this Agreement after taking into account the imposition of the excise tax
under section 4999 of the Internal Revenue Code, if applicable.

     5.4  If a Change in Control occurs during the Term of this Agreement,
Employee may thereafter be entitled to a payment set forth in section 5.3.2 in

          5.4.1  RESIGNATION FOR GOOD REASON. The payments set forth in section
                 ---------------------------
5.3.2 hereof shall apply if, after a Change of Control but within one year
thereafter,

                                       6
<PAGE>
 
Employee Resigns for Good Reason, upon the happening of one or more of the
following events (unless such event or occurrence is applied generally to all
officers and employees of Employer and any parent or successor of any of them),
any of which will constitute Good Reason for Employee's Resignation:

                 5.4.1.1  Without Employee's express written consent, Employee's
assignment to any duties substantially inconsistent with Employee's position,
duties, responsibilities and status with Employer immediately prior to a Change
in Control, or any removal of Employee from any such position to a position
substantially inferior to such prior position;

                 5.4.1.2  A reduction by Employer of Employee's Salary or of any
bonus compensation formula applicable to Employee as in effect prior to a Change
in Control;

                 5.4.1.3  A failure by Employer to maintain any of the employee
benefits to which Employee was entitled prior to a Change in Control at a level
substantially similar to or greater than that in effect prior to a Change in
Control, through the continuation of the same or substantially similar plans,
programs and policies;

                 5.4.1.4  The failure by Employer to provide Employee with the
same number of paid vacation days and leave to which Employee would be entitled
as salaried employee of Employer, or any parent or successor of Employer;

                 5.4.1.5  Employer requiring Employee to travel on employer's
business to an extent substantially greater than Employee's present business
travel obligations; or the relocation of Employee's office at least sixty (60)
miles from its current location, without Employee's consent; and

                 5.4.1.6  The failure of the Bank to obtain the assumption of
this Agreement by any successor of Employer as contemplated in section 10.2
below.

          5.4.2  The events described above are the only events which shall
constitute Good Reason.

6.   CERTAIN RETIREMENT BENEFITS
     ---------------------------

     6.1  Subject to the special terms and conditions contained below, upon
cessation of Employee's employment with Employer, if the Employee has reached
the Retirement Age, or as soon thereafter as Employee reaches the Retirement
Age, the Bank hereby agrees that the Employee and Employee's spouse shall become
the joint owners (with 

                                       7
<PAGE>
 
right of survival) with the Bank of the annual increase of the cash surrender
value of the policy thereafter arising; however, the Employee's (and Employee's
spouse's) right to draw against such increase (such draw to reduce eventual
death benefits) shall never exceed $60,000 per 12-month period (the "Retirement
Draw Benefit"). The shared right to ownership of this increase shall continue
for the lifetime of the Employee and the lifetime of the Employee's surviving
spouse, but in no event longer than 40 years.

                 6.1.1  The Retirement Draw Benefit will be made available by
means of a split-dollar insurance policy which is to be purchased by the Bank
within thirty (30) days of the date of this Agreement, and for which the premium
payment split between the Bank and Employee and the payment terms are outlined
in Exhibit B to this Agreement.

                 6.1.2  Subject to the provisions of sections 6.1.3 and 6.1.4
herein, Employee's right to the Retirement Draw Benefit shall not fully vest
unless he has been employed by Employer for seven (7) years from the Effective
Date. If Employee's employment with Employer ends any time before a date one (1)
year from the date of this Agreement (the "Anniversary Date"), Employee will not
have any right to, or interest in, the Retirement Draw Benefit. If Employee's
employment ends at any time after the Anniversary Date, but prior to the seven
(7) year date of full vesting, Employee's right to one-seventh (1/7) of the
Retirement Draw Benefit--i.e., the right to draw $8,572, or one-seventh of
$60,000, per 12-month period--will vest on the Anniversary Date, and Employee's
right to the Retirement Draw Benefit will continue to proportionately vest
thereafter on a monthly basis, on the first date of each month following the
Anniversary Date, until employment ends.

                 6.1.3  Subject to the provisions of section 6.1.2 herein, if
prior to a Change in Control and during the Term hereof, Employee is Terminated
for any reason other than Disability, the vesting of Employee's right to the
Retirement Draw Benefit will cease as of the date of termination. If prior to a
Change of Control and during the Term hereof, Employee is Terminated by reason
of Disability, the vesting of Employee's right to the Retirement Draw Benefit
will cease as of the date of termination unless the Board in its sole and
absolute discretion approves additional vesting.

                 6.1.4  Notwithstanding the provisions of section 6.1.2 herein,
if after a Change in Control and during the Term hereof, Employee is Terminated,
or Resigns for Good Reason, as provided in section 5.4.1 herein, Employee's
right to the Retirement Draw Benefit shall immediately vest in full, and such
benefit shall become available to Employee when Employee reaches Retirement Age.

under this Agreement all federal, state, city or other taxes or deductions as

construction, application or breach of any of the terms, covenants or conditions
of this Agreement, and all claims relating to or arising from Employee's
employment or Termination, including all statutory claims (including but not
limited to all statutes dealing with employment discrimination), shall on a
timely written request of one party served upon the other, be submitted to
arbitration and be governed by the California Arbitration Act as set forth in
the California Code of Civil Procedure (presently sections 1280 et seq.). The
                                                                -- ---        
parties agree that any written request for arbitration must be made within one
year after the initiating party first learned or should have learned in the
exercise of reasonable diligence of the essential facts upon which the claim is
based, or first suffered any harm, or first learned or should have learned in
the exercise of reasonable diligence of the breach of this Agreement, whichever
is earlier.  Any claim not raised within such time limitation shall be waived
and forever barred.  The arbitration shall take place in Santa Clara County,
California.

     8.2    The parties may agree upon one arbitrator, but in the event they
cannot agree, there shall be three (3), one named in writing by each of the
parties within ten (10) days after demand for arbitration is given, and a third
chosen by the two so appointed; provided further that if the two appointed
cannot agree on the choice, then application shall be made to a presiding judge
of the Santa Clara County Superior Court for the purpose of designating a third
arbitrator. The applying party (who may suggest in such application the names of
a suitable third arbitrator) shall provide the other party at least 48 hours
prior notice of the application so that such other party may have the
opportunity to submit one or more names of persons suitable to serve as the
designated third arbitrator. The presiding judge shall have discretion to
designate the third arbitrator from among the names suggested by either party or
from among any other persons such judge deems appropriate. The cost of such
arbitration, including reasonable attorneys' fees, shall be borne by the losing
party or in such proportions as the arbitrator(s) shall decide. Arbitration
shall be the exclusive remedy of the parties and the award of the arbitrator(s)
shall be final and binding upon the parties.

          1.   Obligation. Steven C. Smith, an individual ("Maker") who is 
               ----------
currently an executive employee of Cupertino National Bank & Trust (the "Bank"),
for value received, hereby promises to pay to the Bank at 20230 Stevens Creek 
Boulevard, Cupertino, California 95014, the principal amount of one hundred 
ninty thousand, one hundred eighty-six dollars ($190,186). This Note is

          If Maker ceases to be employed by Bank before Retirement Age, such 
that incentive or bonus compensation is no longer earned by Maker under any Bank
plan, Maker shall have no obligation to make further payments on this Note until
the death benefit provision is implemented.

          Maker further agrees that the balance of this Note, if any, unpaid at 
Maker's death shall be due and payable upon such death, and Maker hereby 
authorizes Bank to obtain from Maker the payoff of such unpaid balance by 
applying the death benefit proceeds under the Life Insurance. To the extent 
such death benefit proceeds are insufficient to pay in full the unpaid balance 
of this Note, any remaining balance after application of the entire death 
benefit proceeds shall  be deemed extinguished and no longer an obligation of 
Maker or Maker's estate.

          All payments received shall be applied first to interest, if any, then
accrued, and then to principal.

          4.   Prepayments; Application. This Note may be prepaid in whole or 
               -----------------------

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

default shall continue for thirty (30) days after Bank provides written notice 
to Maker of such default.

          6.   Remedies. If an Event of Default shall occur, any indebtedness of
               --------
Maker under this Note shall, at Bank's option and without notice, become 
immediately due and payable without presentment, demand, protest or notice of 
dishonor, all of which are hereby expressly waived by Maker; and Holder shall 
have all of the rights, powers and remedies available under this Note, all of 
which rights, powers and remedies may be exercised at any time by Bank and from 
time to time after the occurrence of an Event of Default. All of the rights,
powers and remedies of Bank in connection with this Note are cumulative and not
exclusive and shall be in addition to any other rights, powers or remedies
provided by law or equity.

          7.   Costs of Collection. If this Note is not paid when due, whether 
               -------------------
at maturity or by acceleration, Maker promises to pay all costs incurred by the 
Bank collecting the amounts due hereunder, including reasonable attorneys' fees.


          8.   Waiver. Presentment, demand, protest, notices of protest, 
               ------

waived, except notices required by this Note. No single or partial exercise of

pertaining to this Note shall preclude other or further exercises thereof or the
exercise of any other power.

          9.   Special Principal/Interest Reduction. Maker and Holder agree that

owned by Maker hereunder to reflect the unvested portion of the Retirement Draw
Benefit which will be foregone by Maker as a result of ceasing employment before
full vesting. By way of example only, if Maker ceases employment when he is
vested with respect to one-seventh of the Retirement Draw Benefit and unvested
with respect to six-sevenths, there shall be a one-time reduction of 
six-sevenths of the principal of this Note; all other terms and conditions shall
remain in effect with respect to payment of the balance.

Section 2.  AGREEMENT TO INDEMNIFY

     (a)  General Agreement.  In the meantime Indemnitee was, is, or becomes a 
Participant in, or is threatened to be made a Participant in, a Proceeding by
reason of (or arising in part out of) an Indemnifiable Event, Bancorp shall
indemnify Indemnitee from and against any and all Expenses to the fullest extent
permitted by law, as the same exists or may hereafter be amended or interpreted
(but in the case of any such amendment or interpretation, only to the extent
that such amendment or interpretation permits Bancorp to provide broader
indemnification rights than were permitted prior to that amendment or
interpretation). The parties to this Agreement intend that this Agreement shall
provide for indemnification in excess of that expressly permitted by the
California Corporations Code, including, without limitation, any indemnification
provided by Bancorp's articles of incorporation, its bylaws, a vote of its
shareholders or disinterested directors, or applicable law. Without limiting the
generality of the foregoing, in a Proceeding initiated by a third party, or by
or in the right of Bancorp, the Indemnitee shall be entitled to indemnification
if the Indemnitee acted in a manner he or she did not believe to be contrary to
the best interests of Bancorp. In addition, in any proceeding initiated by or in
the right of Bancorp which is settled with respect to the Indemnitee, Bancorp
shall indemnify the Indemnitee against any and all Expenses if the Indemnitee
met the standards of conduct set forth in the sentence immediately above, and
court approval of such indemnification will not be required.

     (b)  Initiation of Proceeding.  Notwithstanding anything in this Agreement
to the contrary, Indemnitee shall not be entitled to Indemnification under this
Agreement in connection with any Proceeding initiated by Indemnitee against 
Bancorp or any director or officer of Bancorp unless:

          (i)    Bancorp has joined in or the Board has consented to the 
     initiation of such Proceeding;

          (ii)   the Proceeding is one to enforce indemnification rights under 
     section 5; or

          (iii)  the Proceeding is instituted after a Change in Control and 
     Independent Counsel has approved its initiation.

     (c)  Expense Advances.  If so requested by Indemnitee, Bancorp shall, 
within ten business days of such request, advance all Expenses to Indemnitee (an
"Expense Advance"). Notwithstanding the foregoing, to the extent that the
Reviewing Party determines that Indemnitee would not be permitted to be so
indemnified under applicable law, Bancorp shall be entitled to be reimbursed by
Indemnitee for all such amounts, and Indemnitee hereby agrees to reimburse
Bancorp promptly for the same. If Indemnitee has commenced legal proceedings in
a court of competent jurisdiction to secure a determination that Indemnitee
should be indemnified under applicable law, as provided in section 4, any
determination made by the Reviewing Party that Indemnitee would not be permitted
to be indemnified under applicable law shall not be binding, and Indemnitee
shall not be required to reimburse Bancorp for any Expense Advance until a final
judicial determination is made with respect thereto and all rights of appeal
therefrom have been exhausted or have lapsed. Indemnitee's obligations to
reimburse Bancorp for Expense Advances shall be unsecured and no interest shall
be charged thereon.

     (d)  Mandatory Indemnification.  Notwithstanding any other provision of
this Agreement, to the extent that Indemnitee has been successful on the merits 
in defense of any Proceeding relating in whole or in part to an Indemnifiable 
Event or in defense of any issue or matter in such Proceeding, Indemnitee shall 
be indemnified against all Expenses incurred in connection with that Proceeding.

     (e)  Partial Indemnification.  The Indemnitee also shall be entitled to 
indemnification by Bancorp for a portion of Expenses of Indemnitee is not 
entitled to full indemnification under any applicable law.

     (f)  Prohibited Indemnification.  No indemnification under this Agreement
shall be paid by Bancorp on account of any Proceeding (i) in which judgment is
rendered against Indemnitee for an accounting of profits made from the purchase
or sale by Indemnitee or securities of Bancorp under the

                                      J-3
<PAGE>
 
provisions of section 16(b) of the Exchange Act, or similar provisions of any 
federal, state or local laws, or (ii) if Bancorp is expressly prohibited from 
making payments under this Agreement pursuant to any applicable federal or state
statutes, or any rules or regulations adopted by the FDIC or any other federal 
or state governmental agency which as the power to regulate Bancorp's business.

Section 3.  REVIEWING PARTY

     Before any Change in Control, the Reviewing Party shall be any appropriate
person or body consisting of a member or members of the Board or any other
person or body appointed by the Board who is not a party to the Proceeding for
which Indemnitee is seeking indemnification; after a Change in Control, the
Reviewing Party shall be the Independent Counsel. On all matters arising after a
Change in Control (other than a Change in Control approved by a majority of the
directors of the Board who were directors immediately before such a Change in
Control) concerning the rights of Indemnitee to indemnity payments and Expense
Advances under this Agreement, any other agreement, applicable law, or Bancorp's
articles of incorporation or bylaws now or hereafter in effect relating to
indemnification for Indemnifiable Events, Bancorp shall seek legal advice only
from Independent Counsel selected by Indemnitee and approved by Bancorp (which
approval shall not be unreasonably withheld), and who has not otherwise
performed services for Bancorp or the Indemnitee (other than in connection with
indemnification matters) within the previous five years. The Independent Counsel
shall not include any person who, under the applicable standards of professional
conduct then prevailing, would have a conflict of interest in representing
either Bancorp or Indemnitee in an action to determine Indemnitee's rights under
this Agreement. Such counsel, among other things, shall render a written opinion
to Bancorp and Indemnitee on whether and to what extent the Indemnitee should be
permitted to be indemnified under applicable law. Bancorp agrees to pay the
reasonable fees of the Independent Counsel and to indemnify fully such counsel
against any and all Expenses, including attorneys' fees, claims, liabilities,
loss, and damages arising out of or relating to this Agreement or the engagement
of Independent Counsel under this Agreement.

Section 4.  INDEMNIFICATION PROCESS AND APPEAL

     (a)  INDEMNIFICATION PAYMENT.  Indemnitee shall receive indemnification of 
Expenses from Bancorp in accordance with this Agreement as soon as practicable 
after Indemnitee has made written demand on Bancorp for indemnification, unless 
the Reviewing Party has given a written opinion to Bancorp that Indemnitee is 
not entitled to indemnification under this Agreement or applicable law.

     (b)  SUIT TO ENFORCE RIGHTS.  Regardless of any action by the Reviewing 
Party, if Indemnitee has not received full indemnification  within 30 days after
making a demand in accordance with section 4(a), Indemnitee shall have the right
to enforce its indemnification rights under this Agreement by commencing 
litigation in any court in the State of California seeking an initial 
determination by the court or challenging any determination by the Reviewing 
Party or any aspect thereof.  Bancorp hereby consents to service of process and 
to appear in any such Proceeding.  Any determination by the Reviewing Party not 
challenged by the Indemnitee shall be binding on Bancorp and Indemnitee.  The 
remedy provided for in this section 4 shall be in addition to any other remedies
available to Indemnitee in law or equity.

     (c)  DEFENSE TO INDEMNIFICATION, BURDEN OF PROOF AND PRESUMPTIONS.  It 
shall be a defense to any action brought by Indemnitee against Bancorp to 
enforce this Agreement (other than an action brought to enforce a claim for 
Expenses incurred in defending a Proceeding in advance of its final disposition)
that it is not permissible, under this Agreement or applicable law, for Bancorp 
to indemnify Indemnitee for the amount claimed.  In connection with any such 
action or any determination by the Reviewing Party or otherwise on whether 
Indemnitee is entitled to be indemnified under this Agreement, the burden of 
proving such a defense or determination shall be on Bancorp.  Neither the 
failure of the Reviewing Party or Bancorp (including its Board, independent 
legal counsel, or its shareholders) to have made a determination before the 
commencement of such action by Indemnitee that indemnification is proper under 
the circumstances because the Indemnitee has met the standard of conduct set 
forth in this Agreement or under applicable law, as the case may be, nor an 
actual

                                      J-4
<PAGE>
 
determination by the Reviewing Party or Bank (including its Board, independent 
legal counsel, or its shareholders) that the Indemnitee has not met such 
applicable standard of conduct, shall be a defense to the action or create a 
presumption that the Indemnitee has not met the applicable standard of conduct.
For purposes of this Agreement, the termination of any claim, action, suite, or 
proceeding, by judgment, order settlement (whether with or without court 
approval), conviction, or on a plea of nolo contendere, or its equivalent, shall
not create a presumption that Indemnitee did not meet any particular standard of
conduct or have any particular belief or that a court has determined that 
indemnification is not permitted by applicable law.

Section 5.  INDEMNIFICATION FOR EXPENSES INCURRED IN ENFORCING RIGHTS.

     Bancorp shall indemnify Indemnitee against any and all Expenses incurred by
the Indemnitee in enforcing his or her rights under this Agreement.  If 
requested by Indemnitee, Bancorp shall, within ten business days of such 
request, advance to Indemnitee such Expenses as are incurred by Indemnitee in 
connection with any claim asserted against or action brought by Indemnitee for:

          (a)  Indemnification of Indemnitee by Bancorp under this Agreement, or
     any other agreement, or under applicable law, or Bancorp's articles of
     incorporation or bylaws now or hereafter in effect relating to
     indemnification for Indemnifiable Events, and/or

          (b)  recovery under directors' and officers' liability insurance 
     policies maintained by Bancorp, for amounts paid in settlement if the 
     Independent Counsel has approved the settlement.

     Bancorp shall not settle any Proceeding in any manner that would impose any
penalty or limitation on Indemnitee without Indemnitee's written consent.  
Neither Bancorp nor the Indemnitee will unreasonably withhold its consent to any
proposed settlement.  Bancorp shall not be liable to indemnify the Indemnitee 
under this Agreement with regard to any judicial award if Bancorp was not given 
a reasonable and timely opportunity, at its expense, to participate in the 
defense of such action; however, Bancorp's liability under this Agreement shall 
not be excused if participation in the Proceeding by Bancorp was barred by this 
Agreement.

Section 6.  ESTABLISHMENT OF TRUST

     In the event of a Change in Control or a Potential Change in Control, 
Bancorp shall, on written request by Indemnitee, create a trust for the benefit 
of the Indemnitee ("the Trust") and from time to time on written request of 
Indemnitee shall fund the Trust in an amount sufficient to satisfy any and all 
Expenses reasonably anticipated at the time of each such request to be incurred 
in connection with investigating, preparing for, participating in, and/or 
defending any Proceeding relating to an Indemnifiable Event.  The amount or 
amounts to be deposited in the Trust under the foregoing funding obligation 
shall be determined by the Reviewing Party.  The terms of the Trust shall 
provide that on a Change in Control:

          (a)  The Trust shall not be revoked or the principal invaded without 
    the written consent of the Indemnitee.

          (b)  The Trustee shall advance, within ten business days of a request 
     by Indemnitee, all Expenses to the Indemnitee (provided that the Indemnitee
     hereby agrees to reimburse the Trust under the same circumstances for which
     the Indemnitee would be required to reimburse Bancorp under section 2(c) of
     this Agreement).

          (c)  The Trust shall continue to be funded by Bancorp in accordance 
     with the funding obligation set forth in this section 6.

          (d)  The Trustee shall promptly pay to the Indemnitee all amounts for 
     which the Indemnitee shall be entitled to indemnification under this 
     Agreement or otherwise.

          (e)  All unexpended funds in the Trust shall revert to Bancorp on a 
     final determination by the Reviewing Party or a court of competent
     jurisdiction that the Indemnitee has been fully indemnified under the terms
     of this Agreement.

                                      J-5
<PAGE>
 
    The Trustee shall be chosen by the Indemnitee subject to the approval of the
Reviewing Party. Nothing in this section 6 shall relieve Bancorp of any of its
obligations under this Agreement.  All income earned on the assets held in the
Trust shall be reported as income by Bancorp for federal, state, local and
foreign tax purposes.  Bancorp shall pay all costs of establishing and
maintaining the Trust and shall indemnify the Trustee against any and all
Expenses, including attorneys' fees, claims, liabilities, loss, and damages
arising out of or relating to this Agreement or the establishment and
maintenance of the Trust.

Section 7.  NOTIFICATION AND DEFENSE OF CLAIM

    Promptly after receipt by Indemnitee of notice of the commencement of any 
Proceeding against Indemnitee for which Indemnitee will seek indemnification 
under this Agreement, Indemnitee will notify Bancorp of the commencement 
thereof; but the omission to so notify Bancorp will not relieve it from any 
liability which it may have to Indemnitee otherwise than under this Agreement.  
With respect to any Proceeding as to which Indemnitee so notifies Bancorp:

          (a)  Bancorp will be entitled to participate in the Proceeding at its
     own expense.

          (b)  Except as otherwise provided below, to the extent that it may
     wish, Bancorp jointly with any other indemnifying party similarly notified,
     will be entitled, provided it is advancing to Indemnitee all of the costs
     and expenses required under this Agreement, to assume the defense of the
     Proceeding with counsel satisfactory to Indemnitee.  After notice from
     Bancorp to Indemnitee of its election to assume the defense of the
     Proceeding, Bancorp will not be liable to Indemnitee under this Agreement
     for any legal or other expenses subsequently incurred by Indemnitee in
     connection such defense other than reasonable costs of investigation or as
     otherwise provided below.  Indemnitee shall have the right to employ his or
     her counsel in such Proceeding, but the fees and expenses of such counsel
     incurred after notice from Bancorp of its assumption of such defense shall
     be at the expense of Indemnitee unless (i) the employment of counsel by
     Indemnitee has been authorized by Bancorp, (ii) Indemnitee shall have
     reasonably concluded that there may be a conflict of interest between
     Bancorp and Indemnitee in the conduct of the defense of the proceeding or
     (iii) Bancorp shall not, in fact, have employed counsel to assume the
     defense of the Proceeding, in each of which cases the fees and expenses of
     counsel shall be at the expense of Bancorp.  Bancorp shall not be entitled
     to assume the defense of any Proceeding brought by or on behalf of Bancorp
     or as to which Indemnitee shall have made the conclusion provided for in 
     (ii) above.

          (c)  Bancorp shall not be liable to indemnify Indemnitee under this 
     Agreement for any amounts paid in settlement of any Proceeding without 
     Bancorp's written consent.  Bancorp shall not settle any action or claim in
     any manner which would impose any obligation or limitation on Indemnitee
     without Indemnitee's written consent.  Neither Bancorp nor Indemnitee will 
     unreasonably withhold its/his/her consent to any proposed settlement.

Section 8.  NONEXCLUSIVITY

     The rights of Indemnitee under this Agreement shall be in addition to any 
other rights Indemnitee may have under Bancorp's articles of incorporation, 
bylaws, applicable law, or otherwise.  To the extent that a change in applicable
law (whether by statute or judicial decision) permits greater indemnification by
agreement than would be afforded currently under Bancorp's articles of 
incorporation, bylaws, applicable law, or this Agreement, it is the intent of 
the parties that Indemnitee enjoy by this Agreement the greater benefits 
afforded by such change.

Section 9.  LIABILITY INSURANCE

     To the extent Bancorp maintains an insurance policy or policies providing 
directors' and officers' liability insurance, Indemnitee shall be covered by 
such policy or policies, in accordance with its or their terms, to the maximum 
extent of the coverage available for any Bank director or officer.

                                      J-6

Section 10.  PERIOD OF LIMITATIONS

     No legal action shall be brought, and no cause of action shall be asserted,
by or on behalf of Bancorp or any affiliate of Bancorp against Indemnitee, 
Indemnitee's spouse, heirs, executors, or personal or legal representatives, 
after the expiration of two years from the date of accrual of such cause of 
action, or such longer period as may be required by state law under the 
circumstances.  Any claim or cause of action of Bancorp or its affiliate shall 
be extinguished and deemed released unless asserted by the timely filing of a 
legal action within such period; provided, that if any shorter period of 
limitations is otherwise applicable to any such cause of action, this shorter 
period shall govern.

Section 11.  AMENDMENT OF THIS AGREEMENT

     No supplement, modification, or amendment of this Agreement shall be 
binding unless executed in writing by both of the parties to it.  No waiver of 
any of the provisions of this Agreement shall operate was a waiver of any other 
provisions of this Agreement (whether or not similar), nor shall such waiver 
constitute a continuing waiver.  Except as specifically provided in this 
Agreement, no failure to exercise or delay in exercising any right or remedy 
under it shall constitute a waiver of the right or remedy.

Section 12.  SUBROGATION

     In the event of payment under this Agreement, Bancorp shall be subordinated
to the extent that payment to all of the rights or recovery of Indemnitee, who 
shall execute all papers required and shall do everything that may be necessary 
to secure such rights, including the execution of any documents necessary to 
enable Bancorp effectively to bring suit to enforce such rights.

Section 13.  NO DUPLICATION OF PAYMENTS

     Bancorp shall not be liable under this Agreement to make any payment in 
connection with any claim made against Indemnitee to the extent Indemnitee has 
otherwise received payment (under any insurance policy, bylaw, or otherwise) of 
the amounts otherwise indemnifiable under this Agreement.

Section 14.  BINDING EFFECT

     This Agreement shall be binding on and inure to the benefit of and be
enforceable by the parties to it and their respective successors (including any
direct or indirect successor by purchase, merger, consolidation, or otherwise to
all or substantially all of Bancorp's business or assets or both), assigns,
spouses, heirs, and personal and legal representatives. Bancorp shall require
and cause any successor (whether direct or indirect, by purchase, merger,
consolidation, or otherwise) to all, substantially all, or a substantial part,
of Bancorp's business or assets or both, by written agreement in form and
substance satisfactory to Indemnitee, expressly to assume and agree to perform
this Agreement in the same manner and to the same extent that Bancorp would be
required to perform if no such succession had taken place. The indemnification
provided under this Agreement shall continue for Indemnitee for any action taken
or not taken while serving in an indemnified capacity pertaining to an
Indemnifiable Event even though Indemnitee may have ceased to serve in such
capacity at the time of any proceeding.

Section 15.  SEVERABILITY

     If any portion of this Agreement shall be held by a court of competent
jurisdiction to be invalid, void, or otherwise unenforceable, the remaining
provisions shall remain enforceable to the fullest extent permitted by law.
Furthermore, to the fullest extent possible, the provisions of this Agreement
(including, without limitation, each portion of this Agreement containing any
provision held to be invalid, void, or otherwise unenforceable, that is not
itself invalid, void or unenforceable) shall be construed so as to give effect
to the intent manifested by the provision held invalid, void, or unenforceable.

      Directors of any other series of Preferred Stock whether or not the
      powers, preferences and rights of such other series shall be fixed by the
      Board of Directors as senior to, or on a parity with, the powers,

      (f)  Subject to the provisions of section (e), shares of any series of
      Preferred Stock may be issued from time to time as the Board of Directors
      of the Corporation shall determine and on such terms and for such
      consideration as shall be fixed by the Board of Directors.

      (g)  Shares of Common Stock may be issued from time to time as the Board
      of Directors of the Corporation shall determine and on such terms and for
      such consideration as shall be fixed by the Board of Directors.

      (h)  The authorized amount of shares of Common Stock and of Preferred
      Stock may, without a class or series vote, be increased or decreased from

      constituting the entire Board shall be not less than five nor more than
      twenty-five as fixed from time to time by vote of a majority of the whole
      Board, provided, however, that the number of directors shall not be
      reduced so as to shorten the term of any director at the time in office,
      and provided further, that the number of directors constituting the whole
      Board shall be twenty-four until otherwise fixed by a majority of the
      whole Board.

      (b)  The Board of Directors shall be divided into three classes, as nearly
      equal in number as the then total number of directors constituting the
      whole Board permits, with the term of office of one class expiring each
      year.  At the annual meeting of stockholders in 1982, directors of the
      first class shall be elected to hold office for a term expiring at the
      next succeeding annual meeting, directors of the second class shall be
      elected to hold office for a term expiring at the second succeeding annual
      meeting and directors of the third class shall be elected to hold office
      for a term expiring at the third succeeding annual meeting.  Any vacancies
      in the Board of Directors for any reason, and any newly created
      directorships resulting from any increase in the directors, may be filled
      by the Board of Directors, acting by a majority of the directors then in
      office, although less than a quorum, and any directors so chosen shall
      hold office until the next annual election of directors.  At such
      election, the stockholders shall elect a successor to such director to
      hold office until the next election of the class for which such director
      shall have been chosen and until his successor shall be elected and
      qualified.  No decrease in the number of directors shall shorten the term
      of any incumbent director.

      (c)  Notwithstanding any other provisions of this Charter or Act of
      Incorporation or the By-Laws of the Corporation (and notwithstanding the
      fact that some lesser percentage may be specified by law, this Charter or
      Act of Incorporation or the By-Laws of the Corporation), any director or

      meeting is given to stockholders, such written notice shall be delivered
      or mailed, as prescribed, to the Secretary of the Corporation not later
      than the close of the seventh day following the day on which notice of the
      meeting was mailed to stockholders. Notice of nominations which are

      declare to the meeting that a nomination was not made in accordance with
      the foregoing procedure, and if he should so determine, he shall so
      declare to the meeting and the defective nomination shall be disregarded.

      (g)  No action required to be taken or which may be taken at any annual or
      special meeting of stockholders of the Corporation may be taken without a
      meeting, and the power of stockholders to consent in writing, without a
      meeting, to the taking of any action is specifically denied.

      (f)  Subject to the provisions of section (e), shares of any series of
      Preferred Stock may be issued from time to time as the Board of Directors
      of the Corporation shall determine and on such terms and for such
      consideration as shall be fixed by the Board of Directors.

      (g)  Shares of Common Stock may be issued from time to time as the Board
      of Directors of the Corporation shall determine and on such terms and for
      such consideration as shall be fixed by the Board of Directors.

      (h)  The authorized amount of shares of Common Stock and of Preferred

      conducted and managed by a Board of Directors.  The number of directors
      constituting the entire Board shall be not less than five nor more than
      twenty-five as fixed from time to time by vote of a majority of the whole
      Board, provided, however, that the number of directors shall not be
      reduced so as to shorten the term of any director at the time in office,
      and provided further, that the number of directors constituting the whole
      Board shall be twenty-four until otherwise fixed by a majority of the
      whole Board.

      (b)  The Board of Directors shall be divided into three classes, as nearly
      equal in number as the then total number of directors constituting the
      whole Board permits, with the term of office of one class expiring each
      year.  At the annual meeting of stockholders in 1982, directors of the
      first class shall be elected to hold office for a term expiring at the
      next succeeding annual meeting, directors of the second class shall be
      elected to hold office for a term expiring at the second succeeding annual
      meeting and directors of the third class shall be elected to hold office
      for a term expiring at the third succeeding annual meeting.  Any vacancies
      in the Board of Directors for any reason, and any newly created
      directorships resulting from any increase in the directors, may be filled
      by the Board of Directors, acting by a majority of the directors then in
      office, although less than a quorum, and any directors so chosen shall
      hold office until the next annual election of directors.  At such
      election, the stockholders shall elect a successor to such director to
      hold office until the next election of the class for which such director
      shall have been chosen and until his successor shall be elected and
      qualified.  No decrease in the number of directors shall shorten the term
      of any incumbent director.

      Incorporation or the By-Laws of the Corporation (and notwithstanding the
      fact that some lesser percentage may be specified by law, this Charter or
      Act of Incorporation or the By-Laws of the Corporation), any director or

      meeting is given to stockholders, such written notice shall be delivered
      or mailed, as prescribed, to the Secretary of the Corporation not later
      than the close of the seventh day following the day on which notice of the
      meeting was mailed to stockholders.  Notice of nominations which are

      declare to the meeting and the defective nomination shall be disregarded.

      special meeting of stockholders of the Corporation may be taken without a
      meeting, and the power of stockholders to consent in writing, without a
      meeting, to the taking of any action is specifically denied.

      issued by reason of any increase of the authorized capital stock of the
      Corporation of any class or series, or bonds, certificates of
      indebtedness, debentures or other securities convertible into or

      of the Corporation shall determine and on such terms and for such
      consideration as shall be fixed by the Board of Directors.

      (g)  Shares of Common Stock may be issued from time to time as the Board
      of Directors of the Corporation shall determine and on such terms and for
      such consideration as shall be fixed by the Board of Directors.

      (h)  The authorized amount of shares of Common Stock and of Preferred

      constituting the entire Board shall be not less than five nor more than
      twenty-five as fixed from time to time by vote of a majority of the whole
      Board, provided, however, that the number of directors shall not be
      reduced so as to shorten the term of any director at the time in office,
      and provided further, that the number of directors constituting the whole
      Board shall be twenty-four until otherwise fixed by a majority of the
      whole Board.

      (b)  The Board of Directors shall be divided into three classes, as nearly
      equal in number as the then total number of directors constituting the
      whole Board permits, with the term of office of one class expiring each
      year.  At the annual meeting of stockholders in 1982, directors of the
      first class shall be elected to hold office for a term expiring at the
      next succeeding annual meeting, directors of the second class shall be
      elected to hold office for a term expiring at the second succeeding annual
      meeting and directors of the third class shall be elected to hold office
      for a term expiring at the third succeeding annual meeting.  Any vacancies
      in the Board of Directors for any reason, and any newly created
      directorships resulting from any increase in the directors, may be filled
      by the Board of Directors, acting by a majority of the directors then in
      office, although less than a quorum, and any directors so chosen shall
      hold office until the next annual election of directors.  At such
      election, the stockholders shall elect a successor to such director to
      hold office until the next election of the class for which such director
      shall have been chosen and until his successor shall be elected and
      qualified.  No decrease in the number of directors shall shorten the term
      of any incumbent director.

      (c)  Notwithstanding any other provisions of this Charter or Act of
      Incorporation or the By-Laws of the Corporation (and notwithstanding the
      fact that some lesser percentage may be specified by law, this Charter or
      Act of Incorporation or the By-Laws of the Corporation), any director or

      meeting is given to stockholders, such written notice shall be delivered
      or mailed, as prescribed, to the Secretary of the Corporation not later
      than the close of the seventh day following the day on which notice of the
      meeting was mailed to stockholders.  Notice of nominations which are

      declare to the meeting and the defective nomination shall be disregarded.

      special meeting of stockholders of the Corporation may be taken without a
