     $30,928,000

       FLOATING RATE JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURE

                  DUE September 15, 2028 Series A/Series B

     Greater Bay Bancorp, a California corporation (the "Corporation," which
term includes any successor Person under the Indenture hereinafter referred to),
for value received, hereby promises to pay to GBB Capital II or its registered
assigns, the principal sum of Thirty Million Nine Hundred Twenty-Eight Thousand
Dollars ($30,928,000) on September 15, 2028 (the "Maturity Date"), unless
previously prepaid, and to pay interest on the outstanding principal amount
hereof from August 12, 1998, or from the most recent interest payment date (each
such date, an "Interest Payment Date") to which interest has been paid or duly
provided for, quarterly (subject to deferral as set forth herein) in arrears on
March 15, June 15, September 15 and December 15 of each year, commencing
December 15, 1998 at the rate per annum, reset quarterly, equal to 3-month LIBOR
(as defined in the Indenture) plus 150 basis points until the principal hereof
shall have become due and payable, 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 same rate per
annum compounded quarterly ("Compounded Interest").  The amount of interest
payable on any Interest Payment Date shall be computed on the basis of the
actual number of days elapsed and a 360-day year.  In the event that any date on
which the principal of or interest on this Security is payable is not a Business
Day (as defined in the Indenture), then the payment payable on such date will be
made on the next succeeding day that is a Business Day, except that if such next
succeeding Business Day falls in the next succeeding calendar month such payment
shall be made on the immediately preceding Business Day (and without any
interest or other payment in respect of any such delay), with the same force and
effect as if made on such date.  Pursuant to the Indenture, in certain
circumstances the Corporation will be required to pay Additional Sums (as
defined in the Indenture) with respect to this Security.  Pursuant to the
Registration Rights Agreement and the Liquidated Damages Agreement, in certain
limited circumstances the Corporation will be required to pay Liquidated Damages
(as defined in the Registration Rights Agreement and the Liquidated Damages
Agreement) with respect to this Security.

     The interest installment so payable, and punctually paid or duly provided
for, on any Interest Payment Date will, as provided in the Indenture, be paid to
the Person in whose name this Security (or one or more Predecessor Securities,
as defined in said Indenture) is registered at the close of business on the
regular record date for such interest installment, which shall be at the close
of business on the first day of the month in which the relevant Interest Payment
Date falls.  Any such interest installment not punctually paid or duly provided
for shall forthwith cease to be payable to the holders on such regular record
date and may 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 

                                       3

 
to be fixed by the Debenture Trustee for the payment of such defaulted
interest, notice whereof shall be given to the holders of Securities not less
than 10 days prior to such special record date, or may be paid at any time in
any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities may be listed, and upon such
notice as may be required by such exchange, all as more fully provided in the
Indenture.

     The principal of and interest (including Compounded Interest and Additional
Sums, if any) and Liquidated Damages, if any, on this Security shall be payable
at the office or agency of the Debenture Trustee maintained for that purpose in
any coin or currency of the United States of America that at the time of payment
is legal tender for payment of public and private debts; provided, however, that
                                                         --------  -------      
payment of interest may be made at the option of the Corporation by (i) check
mailed to the holder at such address as shall appear in the Security Register or
(ii) transfer to an account maintained by the Person entitled thereto, provided
that proper written transfer instructions have been received by the relevant
record date.  Notwithstanding the foregoing, so long as the holder of this
Security is the Property Trustee of GBB Capital II, the payment of the principal
of and interest (including Compounded Interest and Additional Sums, if any) and
Liquidated Damages, if any, on this Security will be made at such place and to
such account as may be designated by such Property Trustee.

     The indebtedness evidenced by this Security is, to the extent provided in
the Indenture, subordinate and junior in right of payment to the prior payment
in full, of all Senior Indebtedness, 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 Debenture Trustee on his or her behalf to take such
action as may be necessary or appropriate to acknowledge or effectuate the
subordination so provided and (c) appoints the Debenture Trustee his or her
attorney-in-fact for any and all such purposes.  Each holder hereof, by his or
her acceptance hereof, hereby waives all notice of the acceptance of the
subordination provisions contained herein and in the Indenture by each holder of
Senior Indebtedness, whether now outstanding or hereafter incurred, and waives
reliance by each such holder upon said provisions.

     This Security shall not be entitled to any benefit under the Indenture or
be valid or become obligatory for any purpose until the Certificate of
Authentication hereon shall have been signed by or on behalf of the Debenture
Trustee.

     The provisions of this Security are continued on the reverse side hereof
and such provisions shall for all purposes have the same effect as though fully
set forth at this place.

                                       4

 
     IN WITNESS WHEREOF, the Corporation has caused this instrument to be duly
executed and sealed this 12th day of August, 1998.

                                      not in its individual capacity but solely 
                                      as Debenture Trustee

                                           Authorized Signatory

                                       5

 
     This Security is one of the Securities of the Corporation (herein sometimes
referred to as the "Securities"), specified in the Indenture, all issued or to
be issued under and pursuant to an Indenture, dated as of August 12, 1998 (the
"Indenture"), duly executed and delivered between the Corporation and Wilmington
Trust Company, as Debenture Trustee (the "Debenture Trustee"), to which
Indenture reference is hereby made for a description of the rights, limitations
of rights, obligations, duties and immunities thereunder of the Debenture
Trustee, the Corporation and the holders of the Securities.

     Upon the occurrence and continuation of a Special Event (as defined in the
Indenture) prior to September 15, 2008 (the "Initial Optional Redemption Date"),
the Corporation shall have the right, at any time within 90 days following the
occurrence of such Special Event, to prepay this Security in whole (but not in
part) at the Prepayment Price.  "Prepayment Price" shall mean, with respect to
any prepayment of this Security, an amount in cash equal to 100% of the
principal amount to be prepaid plus any accrued and unpaid interest (including
Compounded Interest and Additional Sums, if any) and Liquidated Damages, if any,
thereon to the date of such prepayment.

     In addition, the Corporation shall have the right to prepay this Security,
in whole or in part, at any time on or after the Initial Optional Redemption
Date (an "Optional Prepayment"), at the Prepayment Price.

     The Prepayment Price shall be paid prior to 12:00 noon, Eastern time, on
the date of such prepayment or at such earlier time as the Corporation
determines, provided that the Corporation shall deposit with the Debenture
            --------                                                      
Trustee an amount sufficient to pay the Prepayment Price by 10:00 a.m., Eastern
time, on the date such Prepayment Price is to be paid.  Any prepayment pursuant
to this paragraph will be made upon not less than 30 days' nor more than 60
days' prior written notice.

     If the Securities are only partially prepaid by the Corporation pursuant to
an Optional Prepayment, the particular Securities to be prepaid shall be
selected on a pro rata basis from the outstanding Securities not previously
called for prepayment; provided, however, that with respect to Securityholders
                       --------  -------                                      
that would be required to hold Securities with an aggregate principal amount of
less than $100,000 but more than an aggregate principal amount of zero as a
result of such pro rata prepayment, the Corporation shall prepay Securities of
each such Securityholder so that after such prepayment such Securityholder shall
hold Securities either with an aggregate principal amount of at least $100,000
or such Securityholder no longer holds any Securities and shall use such method
(including, without limitation, by lot) as the Corporation shall deem fair and
appropriate; provided, further, that any such proration may be made on the basis
             --------  -------                                                  
of the aggregate principal amount of Securities held by each Securityholder
thereof and may be made by making such adjustments as the Corporation deems fair
and appropriate in order that only Securities in denominations of $1,000 or
integral multiples thereof shall be prepaid.  In the event of prepayment of this
Security in part only, a new Security or Securities for the portion hereof that
has not been prepaid will be issued in the name of the holder hereof upon the
cancellation hereof.

                                       6

 
     Notwithstanding the foregoing, any prepayment of Securities by the
Corporation shall be subject to the receipt of any and all required regulatory
approvals.

     In case an Event of Default (as defined in the Indenture) shall have
occurred and be continuing, the principal of all of the Securities may be
declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Indenture.

     The Indenture contains provisions permitting the Corporation and the
Debenture Trustee, with the consent of the holders of a majority in aggregate
principal amount of the Securities at the time outstanding (as defined in the
Indenture), to execute supplemental indentures for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Indenture or of modifying in any manner the rights of the holders of the
Securities; provided, however, that no such supplemental indenture shall,
            --------  -------                                            
without the consent of each holder of Securities then outstanding and affected
thereby, (i) change the Maturity Date of any Security, or reduce the rate or
extend the time of payment of interest thereon (subject to Article XVI of the
Indenture), or reduce the principal amount thereof, or change any of the
prepayment provisions or make the principal thereof or any interest thereon
payable in any coin or currency other than U.S. dollars, or impair or affect the
right of any holder of Securities to institute suit for payment thereof, or (ii)
reduce the aforesaid percentage of Securities the holders of which are required
to consent to any such supplemental indenture.  The Indenture also contains
provisions permitting the holders of a majority in aggregate principal amount of
the Securities at the time outstanding affected thereby, on behalf of all of the
holders of the Securities, to waive any past default in the performance of any
of the covenants contained in the Indenture, or established pursuant to the
Indenture, and its consequences, except a default in the payment of the
principal of or interest on any of the Securities or a default in respect of any
covenant or provision under which the Indenture cannot be modified or amended
without the consent of each holder of Securities then outstanding.  Any such
consent or waiver by the holder of this Security (unless revoked as provided in
the Indenture) shall be conclusive and binding upon such holder and upon all
future holders and owners of this Security and of any Security issued in
exchange herefor or in place hereof (whether by registration of transfer or
otherwise), irrespective of whether or not any notation of such consent or
waiver is made upon this Security.

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Corporation, which
is absolute and unconditional, to pay the principal of and interest (including
Compounded Interest and Additional Sums, if any) and Liquidated Damages, if any,
on this Security at the time and place and at the rate and in the money herein
prescribed.

     So long as no Event of Default shall have occurred and be continuing, the
Corporation shall have the right, at any time and from time to time during the
term of the Securities, to defer payments of interest by extending the interest
payment period (an "Extended Interest Payment Period") of such Securities for a
period not (i) exceeding 20 consecutive quarterly periods, including the first
such quarterly period during such extension period, (ii) extending beyond the
Maturity Date of the 

                                       7

 
Securities or (iii) ending on a date other than an Interest Payment Date, at
the end of which period the Corporation shall pay all interest then accrued
and unpaid (together with interest thereon at the rate specified for the
Securities to the extent that payment of such interest is enforceable under
applicable law). Before the termination of any such Extended Interest Payment
Period, the Corporation may further defer payments of interest by further
extending such Extended Interest Payment Period, provided that such Extended 
                                                 --------          
Interest Payment Period, together with all such previous and further
extensions within such Extended Interest Payment Period, (i) shall not exceed
20 consecutive quarterly periods including the first quarterly period during
such Extended Interest Payment Period, (ii) shall not end on any date other
than an Interest Payment Date, and (iii) shall not extend beyond the Maturity
Date of the Securities. Upon the termination of any such Extended Interest
Payment Period and the payment of all accrued and unpaid interest and any
additional amounts then due, the Corporation may commence a new Extended
Interest Payment Period, subject to the foregoing requirements. No interest
shall be due and payable during an Extended Interest Payment Period, except at
the end thereof, but the Corporation may prepay at any time all or any portion
of the interest accrued during an Extended Interest Payment Period.

     The Corporation has agreed that it will not (i) declare or pay any
dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of the Corporation's capital stock,
(ii) make any payment of principal of or interest or premium, if any, on or
repay, repurchase or redeem any debt securities (including other Debentures) of
the Corporation that rank pari passu with or junior in right of payment to the
Securities or (iii) make any guarantee payments with respect to any guarantee by
the Corporation of the debt securities of any Subsidiary of the Corporation
(including Other Guarantees) if such guarantee ranks pari passu with or junior
in right of payment to the Securities (other than (a) dividends or distributions
of Corporation's capital stock (which includes Common Stock and preferred
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 Capital Securities Guarantee, as defined in the
Indenture, (d) as a result of a reclassification of the Corporation's capital
stock or the exchange or conversion of one class or series of the Corporation's
capital stock for another class or series of the Corporation's capital stock,
(e) the purchase of fractional interests in shares of the Corporation's capital
stock pursuant to the conversion or exchange provisions of such capital stock or
the security being converted or exchanged, and (f) purchases of Common Stock
related to the issuance of Common Stock or rights under any of the Corporation's
benefit or compensation plans for its directors, officers or employees or any of
the Corporation's dividend reinvestment plans), if at such time (1) there shall
have occurred any event of which the Corporation has actual knowledge that (a)
is a Default or  an Event of Default and (b) in respect of which the Corporation
shall not have taken reasonable steps to cure, (2) if such Securities are held
by the Property Trustee of GBB Capital II, the Corporation shall be in default
with respect to its payment of any obligations under the Capital Securities
Guarantee or (3) the Corporation shall have given notice of its election to
exercise its right to commence an Extended Interest Payment Period, and shall
not have rescinded such Notice, and such Extended Interest Payment Period or any
extension thereof shall have commenced and be continuing.

                                       8

 
     Subject to (i) the Corporation having received any required regulatory
approvals and (ii) the Administrative Trustees of GBB Capital II having received
an opinion of counsel to the effect that such distribution will not cause the
holders of Capital Securities to recognize gain or loss for federal income tax
purposes, the Corporation will have the right at any time to liquidate the Trust
and, after satisfaction of liabilities of creditors of the Trust as required by
applicable law, to cause the Securities to be distributed to the holders of the
Trust Securities in liquidation of the Trust.

     The Securities are issuable only in registered form without coupons in
minimum denominations of $100,000 and multiples of $1,000 in excess thereof.  As
provided in the Indenture and subject to the transfer restrictions limitations
as may be contained herein and therein from time to time, this Security is
transferable by the holder hereof on the Security Register of the Corporation,
upon surrender of this Security for registration of transfer at the office or
agency of the Corporation in Wilmington, Delaware accompanied by a written
instrument or instruments of transfer in form satisfactory to the Corporation or
the Debenture Trustee duly executed by the holder hereof or his or her attorney
duly authorized in writing, and thereupon one or more new Securities of
authorized denominations and for the same aggregate principal amount will be
issued to the designated transferee or transferees.  No service charge will be
made for any such registration of transfer, but the Corporation may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in relation thereto.

     Prior to due presentment for registration of transfer of this Security, the
Corporation, the Debenture Trustee, any authenticating agent, any paying agent,
any transfer agent and the security registrar may deem and treat the holder
hereof as the absolute owner hereof (whether or not this Security shall be
overdue and notwithstanding any notice of ownership or writing hereon made by
anyone other than the security registrar for the Securities) for the purpose of
receiving payment of or on account of the principal hereof and (subject to the
Indenture) interest due hereon and for all other purposes, and neither the
Corporation nor the Debenture Trustee nor any authenticating agent nor any
paying agent nor any transfer agent nor any security registrar shall be affected
by any notice to the contrary.

     No recourse shall be had for the payment of the principal of or interest
(including Compounded Interest and Additional Sums, if any) or Liquidated
Damages, if any, on this Security, or for any claim based hereon, or otherwise
in respect hereof, or based on or in respect of the Indenture, against any
incorporator, stockholder, employee, officer or director, past, present or
future, as such, of the Corporation or of any predecessor or successor Person,
whether by virtue of any constitution, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability being,
by the acceptance hereof and as part of the consideration for the issuance
hereof, expressly waived and released.

     All terms used in this Security that are defined in the Indenture shall
have the meanings assigned to them in the Indenture.

                                       9

 
     THE INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF
LAW PRINCIPLES THEREOF.
