APPENDIX A CHARTER OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS OF GREATER

                    PROXY STATEMENT FOR GREATER BAY BANCORP
                      2001 ANNUAL MEETING OF SHAREHOLDERS

                INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

Why Did You Send Me this Proxy Statement?

         We sent you this Proxy Statement and the enclosed proxy card because
our Board of Directors is soliciting your proxy to vote at the 2001 Annual
Meeting of Shareholders. This Proxy Statement summarizes the information you
need to know to cast an informed vote at the Annual Meeting. However, you do not
need to attend the Annual Meeting to vote your shares. Instead, you may simply
complete, sign and return the enclosed proxy card.

         Along with this Proxy Statement, we are also sending you the Greater
Bay Bancorp 2000 Summary Annual Report and Annual Report on Form 10-K for the
year ended December 31, 2000, which includes our financial statements. Greater
Bay Bancorp is also referred to in this Proxy Statement as the "Company."

Who is Entitled to Vote?

         We will begin sending this Proxy Statement, the attached Notice of
Annual Meeting and the enclosed proxy card on or about April 4, 2001 to all
shareholders entitled to vote. Shareholders who were the record owners of
Greater Bay Bancorp Common Stock at the close of business on March 28, 2001 are
entitled to vote. On this record date, there were 42,489,854 shares of Greater
Bay Bancorp Common Stock outstanding. Greater Bay Bancorp Common Stock is our
only class of outstanding stock.

What Constitutes a Quorum?

         A majority of the outstanding shares of Greater Bay Bancorp Common
Stock entitled to vote at the meeting must be present, in person or by proxy, in
order to constitute a quorum. We can only conduct the business of the meeting if
a quorum has been established. We will include proxies marked as abstentions and
broker non-votes in determining the number of shares present at the meeting.

How Many Votes Do I Have?

         Each share of Greater Bay Bancorp Common Stock that you owned at the
close of business on March 28, 2001 entitles you to one vote. The proxy card
indicates the number of votes that you have.

How Do I Vote By Proxy?

         Whether or not you plan to attend the Annual Meeting, we urge you to
complete, sign and date the enclosed proxy card and to return it promptly in the
envelope provided. Returning the proxy card will not affect your right to attend
the Annual Meeting and vote.

         If you properly fill in your proxy card and send it to us in time to
vote, your "proxy" (one of the individuals named on your proxy card) will vote
your shares as you have directed. If you sign the proxy card but do not make
specific choices, your proxy will vote your shares as recommended by the Board
of Directors as follows:

         .   "FOR" the election of all five nominees for director

         .   "FOR" approval of the Bylaws amendment to increase the range of
             authorized directors

         .   "FOR" ratification of the selection of independent accountants for
             2001.

         If any other matter is presented, your proxy will vote in accordance
with the recommendation of the Board of Directors, or, if no recommendation is
given, in accordance with his or her best judgment. At the time this Proxy
Statement went to press, we knew of no matters which needed to be acted on at
the Annual Meeting, other than those discussed in this Proxy Statement.

                                       1


         If you hold your shares of Greater Bay Bancorp Common Stock in "street
name" (that is, through a broker or other nominee) and you fail to instruct your
broker or nominee as to how to vote such shares of common stock, your broker or
nominee may, in its discretion, vote your shares "FOR" the election of the
nominees for director set forth herein, "FOR" the Bylaws amendment to increase
the range of authorized directors and "FOR" ratification of the appointment of
PricewaterhouseCoopers L.L.P. as our independent public accountants for the year
ending December 31, 2001.

May I Change My Vote After I Return My Proxy?

         Yes. If you fill out and return the enclosed proxy card, you may change
your vote at any time before the vote is conducted at the Annual Meeting. You
may change your vote in any one of three ways:

         .   You may send to the Company's Corporate Secretary another completed
             proxy card with a later date.

         .   You may notify the Company's Corporate Secretary in writing before
             the Annual Meeting that you have revoked your proxy.

         .   You may attend the Annual Meeting and vote in person.

How Do I Vote in Person?

         If you plan to attend the Annual Meeting and vote in person, we will
give you a ballot form when you arrive. However, if your shares are held in the
name of your broker, bank or other nominee, you must bring a power of attorney
from your nominee in order to vote at the Annual Meeting.

What Vote is Required to Approve Each Proposal?

Proposal 1:
Elect Five Directors               The five nominees for director who receive
                                   the most votes will be elected. So, if you do
                                   not vote for a particular nominee, or you
                                   indicate "WITHHOLD AUTHORITY" to vote for a
                                   particular nominee on your proxy card, your
                                   vote will not count either "for" or "against"
                                   the nominee. Our Articles of Incorporation do
                                   not permit cumulative voting.

Proposal 2:
Approve Bylaws Amendment           The affirmative vote of a majority of the
                                   outstanding shares is required to approve the
                                   proposal. So, if you "ABSTAIN" from voting,
                                   it has the effect of a vote against this
                                   proposal.

Proposal 3:
Ratify Selection of Independent    The affirmative vote of a majority of the
Public Accountants                 votes cast at the Annual Meeting on this
                                   proposal is required to ratify the selection
                                   of independent public accountants. So, if you
                                   "ABSTAIN" from voting, it has no effect on
                                   the outcome of this proposal.

What are the Costs of Soliciting these Proxies?

         We will pay all the costs of soliciting these proxies. In addition to
mailing proxy soliciting material, our directors, officers and employees also
may solicit proxies in person, by telephone or by other electronic means of
communication for which they will receive no compensation. We will ask banks,
brokers and other institutions, nominees and fiduciaries to forward the proxy
materials to their principals and to obtain authority to execute proxies. We
will then reimburse them for their reasonable expenses. We have hired Georgeson
Shareholder Communications Inc. to seek the proxies of custodians, such as
brokers, who hold shares which belong to other people. This service will cost
the Company approximately $4,000.

                                       2


How Do I Obtain an Annual Report on Form 10-K?

         A copy of Greater Bay Bancorp's Annual Report on Form 10-K for the year
ended December 31, 2000 is included with this Proxy Statement. The Annual Report
on Form 10-K includes a list of exhibits filed with the SEC, but does not
include the exhibits. If you wish to receive copies of the exhibits, we will
send them to you. Expenses for copying and mailing them to you will be your
responsibility. Please write to:

             INFORMATION ABOUT GREATER BAY BANCORP STOCK OWNERSHIP

Does Anyone Own 5% or More of Greater Bay Bancorp's Common Stock?

         No. Greater Bay Bancorp is not aware of anyone who beneficially owns 5%
or more of our outstanding Common Stock. The Securities and Exchange Commission
has defined "beneficial ownership" to mean more than ownership in the usual
sense. For example, a person has beneficial ownership of a share not only if he
owns it in the usual sense, but also if he has the power to vote, sell or
otherwise dispose of the share. Beneficial ownership also includes that number
of shares that a person has the right to acquire within 60 days. Two or more
persons might count as beneficial owners of the same share.

                                       3


How Much of Greater Bay Bancorp's Common Stock is Owned by Directors and
Executive Officers?

         The following table shows, as of March 28, 2001, beneficial ownership
of Greater Bay Bancorp Common Stock by each of Greater Bay Bancorp's directors,
nominees for director and executive officers, and for directors and executive
officers as a group. Unless otherwise indicated in the table below, no director
or executive officer of Greater Bay Bancorp shares beneficial ownership of the
same Greater Bay Bancorp Common Stock with anyone else.

              INFORMATION ABOUT DIRECTORS AND EXECUTIVE OFFICERS

The Board of Directors

         The Board of Directors oversees our business and monitors the
performance of management. In accordance with corporate governance principles,
the Board does not involve itself in day-to-day operations. The directors keep
themselves informed through, among other things, discussions with the Chief
Executive Officer, other key executives and our principal external advisers
(legal counsel, outside auditors, investment bankers and other consultants), by
reading reports and other materials that we send them and by participating in
Board and committee meetings.

         Greater Bay Bancorp's Bylaws currently permit the number of Board
members to range from 9 to 17, leaving the Board authority to fix the exact
number of directors within that range. The Board has fixed the exact number of
directors at 17. A proposal is included in this Proxy Statement to amend the
Bylaws to increase the number of authorized directors from a range of 9 to 17 to
a range of 11 to 21.

         The Board held 15 meetings during 2000. Each incumbent director
attended at least 75% of the total number of Board meetings plus meetings of the
standing committees on which that particular director served.

The Committees of the Board

         The Board may delegate portions of its responsibilities to committees
of its members. These "standing committees" of the Board meet at regular
intervals to attend to their particular areas of responsibility. Our Board has
five standing committees: the Audit Committee, Executive Committee, Loan
Committee, Trust Oversight Committee and Investment/Asset-Liability Management
Committee, referred to as the "Investment/ALCO Committee".

         Audit Committee. The responsibilities of the Audit Committee are
contained in the Audit Committee Report set forth below. During 2000, the Audit
Committee consisted of Messrs. Seiler (Chairman), Hounslow, Libarle, McLaughlin,
Randall and Thoits, each of whom is "independent," as defined by Company policy
and The Nasdaq Stock Market listing standards. The Audit Committee held 7
meetings during 2000.

                            Audit Committee Report

         The following Audit Committee Report does not constitute soliciting
material and should not be deemed filed or incorporated by reference into any
other Company filings under the Securities Act of 1933 or the Securities Act of
1934, except to the extent we specifically incorporate this Report by reference.

         The Audit Committee reports to the Board of Directors and is
responsible for overseeing and monitoring financial accounting and reporting,
the system of internal controls established by management and the audit process
of Greater Bay Bancorp.

         The Audit Committee Charter adopted by the Board sets out the
responsibilities, authority and specific duties of the audit committee. A copy
of the Audit Committee Charter is attached to this Proxy Statement as Appendix
                                                                      --------
A. Pursuant to the charter, the Audit Committee has the following primary
-
responsibilities:

           .   To monitor the integrity of the Company's financial reporting
               process and systems of internal controls regarding finance,
               accounting and legal compliance

           .   To monitor the independence and performance of the Company's
               independent accountants and internal audit function

           .   To recommend annually to the Board of Directors the appointment
               of the independent accountants

                                       6


           .   To monitor the preparation of quarterly and annual financial
               reports

           .   To review the general scope of the annual audit and the fees
               charged by the independent accountants

           .   To provide an avenue of communications among the independent
               accountants, management and the Board of Directors.

         In discharging its oversight responsibility, the Audit Committee has
met and held discussions with management and PricewaterhouseCoopers LLP, the
independent accountants for Greater Bay Bancorp. Management represented to the
Audit Committee that all consolidated financial statements were prepared in
accordance with generally accepted accounting principles, and the Audit
Committee has reviewed and discussed the consolidated financial statements with
management and the independent accountants. The Audit Committee discussed with
the independent accountants matters required to be discussed by Statement on
Auditing Standards No. 61 (Communications with Audit Committees).

         The Audit Committee also obtained from the independent accountants a
formal written statement describing all relationships between Greater Bay
Bancorp and the accountants that bear on the accountants independence consistent
with Independence Standards Board Standard No. 1, Independence Discussions with
Audit Committee. The Audit Committee discussed with the independent accountants
any relationships that may impact on the firm's objectivity and independence and
satisfied itself as to the accountants' independence.

         Based on these discussions and reviews, the Audit Committee recommended
that the Board of Directors approve the inclusion of the Company's audited
consolidated financial statements in the Company's Annual Report on Form 10-K
for the year ended December 31, 2000, for filing with the SEC.

Respectfully submitted by the members of the Audit Committee:

Dated:  April 13, 2001                  Donald H. Seiler, Chairman
                                        John J. Hounslow
                                        Daniel G. Libarle
                                        Glen McLaughlin
                                        Dick J. Randall
                                        Warren R. Thoits

         Executive Committee. Our Executive Committee also acts as our Executive
Compensation Committee and Nominating Committee. In performing its duties as the
Executive Compensation Committee, the Executive Committee determines the salary
and bonus structure of the Company's executive officers and supervises
compensation for our other officers.

         In performing its duties as the Nominating Committee, the Executive
Committee selects management nominees to stand for election as directors. It
also considers nominations made to the Board by shareholders, provided such
nominations comply with the Company's Bylaws. The Executive Committee held 14
meetings during 2000. Mr. Matteson chairs the Executive Committee and Messrs.
Gatto, Kalkbrenner, Lindsay, Randall, Seiler and Thoits also are members.

Compensation Committee Interlocks and Insider Participation

         None of the members of the Executive Committee (which also acts as an
Executive Compensation Committee) serves or has served as an officer or employee
of Greater Bay Bancorp or its subsidiaries, except for Mr. Kalkbrenner, who
serves as the President and Chief Executive Officer of Greater Bay Bancorp. In
addition, Messrs. Matteson, Seiler and Mr. Thoits have an interest in a building
leased by Mid-Peninsula Bank, a subsidiary of the Company. See "Certain
Relationships and Related Transactions."

                                       7


Section 16(a) Beneficial Ownership Reporting Compliance by Directors and
Executive Officers

         Section 16(a) of the Securities Exchange Act of 1934, as amended,
requires our directors and executive officers to file reports with the SEC and
The Nasdaq Stock Market on changes in their beneficial ownership of Greater Bay
Bancorp Common Stock, and to provide the Company with copies of the reports.

         Based solely on our review of these reports or of certifications to us
that no report was required to be filed, we believe that all of our directors
and executive officers complied with all Section 16(a) filing requirements
applicable to them during the 2000 fiscal year, except as stated in this
paragraph. Mr. McLaughlin, failed to file on a timely basis one report on Form 4
during each of 1996, 1997 and 1998, regarding one gift transaction in each year.
He filed a Form 5 on February 7, 2001 covering these transactions. Duncan L.
Matteson failed to file on a timely basis one report on Form 4 regarding one
gift transaction.

How We Compensate Directors

         Greater Bay Bancorp has a policy of compensating directors for their
service on the Board and for their attendance at committee meetings. In 2000,
Duncan Matteson, as Co-Chairman of the Board, received an annual retainer of
$36,000 and John Gatto, as Co-Chairman of the Board, received an annual retainer
of $24,000. Rex Lindsay and Donald Seiler as Vice-Chairmen of the Board, each
received annual retainers of $20,000 in 2000. All other non-officer directors
received annual retainers of $16,000. Mr. Kalkbrenner's compensation is
discussed below in the section entitled "How We Compensate Executive Officers."
The total compensation for the Greater Bay Bancorp Board of Directors in 2000
was $503,667.

         In 2000, committee members received annual retainers as follows: (i)
Audit Committee, $4,000; (ii) Executive Committee, $20,000; (iii) Loan
Committee, $10,000; (iv) Trust Oversight Committee, $4,000; and (v)
Investment/ALCO Committee, $4,000. The Chairmen of these committees received an
additional annual retainer of $2,000 in 2000.

         The Boards of Directors of Greater Bay Bancorp's subsidiary banks
received total fees in 2000, as follows: Bank of Petaluma, $181,200; Bank of
Santa Clara, $134,800; Bay Area Bank, $12,000; Bay Bank of Commerce, $102,650;
Coast Commercial Bank, $142,583; Cupertino National Bank, $26,000; Golden Gate
Bank, $17,166; Mid-Peninsula Bank, $34,500; Mt. Diablo National Bank, $11,838;
and Peninsula Bank of Commerce, $14,000.

         In 2001, each subsidiary bank board member will receive an annual
retainer of $2,000, except that each Bank of Petaluma director will receive an
attendance fee of $600 per meeting through March 2001. Beginning in April 2001,
Bank of Petaluma board members will receive a quarterly retainer of $500.

         In addition, directors are eligible to participate in Greater Bay
Bancorp's 1996 Stock Option Plan and the 1997 Elective Deferred Compensation
Plan. During 2000, Mr. Matteson, Mr. Gatto and the other members of the
Executive Committee received options to purchase 15,000, 12,500 and 10,000
shares, respectively, of our Common Stock at an exercise price of $37.125 per
share, the fair market value of such stock on the date of grant. In addition,
each other non-officer director of Greater Bay Bancorp and the subsidiary bank
boards received options to purchase 7,000 and 500 shares, respectively, of
Greater Bay Bancorp Common Stock at an exercise price of $37.125 per share, the
fair market value of such stock on the date of grant. All stock options granted
to non-officer directors vest in equal annual installments over five-year
periods beginning on the date of grant, subject to continued service on the
Board of Directors. Directors are also entitled to the protection of certain
indemnification provisions in Greater Bay Bancorp's Articles of Incorporation
and Bylaws.

Certain Relationships and Related Transactions

         Greater Bay Bancorp, through its subsidiaries, has had and expects in
the future to have banking transactions in the ordinary course of business with
our directors and officers or associates of our directors and officers. We may
also have banking transactions with corporations of which our directors or
officers may own a controlling interest, or also serve as directors or officers.
These transactions have taken place and will take place on substantially the
same terms, including interest and collateral, as those prevailing for
comparable transactions with others. We believe that these transactions
involving loans did not present more than normal risk of noncollectibility or
present other unfavorable features.

                                       8


         Mid-Peninsula Bank leases its offices at 420 Cowper Street, Palo Alto,
California 94301 from MPB Associates, a tenant-in-common arrangement. Three
directors of Greater Bay Bancorp, Messrs. Matteson, Seiler and Thoits, and four
other directors of Mid-Peninsula Bank, together own an approximately 51%
interest in MPB Associates. The acquisition of Mid-Peninsula Bank's leased
premises by MPB Associates did not result in a change in the terms of the lease.

         The lease has been extended through January 2010. Mid-Peninsula Bank
pays an annual rental of $613,000 for the entire leased space, subject to an
annual rent adjustment of 3.5%. Additionally, Mid-Peninsula Bank 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 lease also contains a
provision granting Mid-Peninsula Bank 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.

         In January 2000, Greater Bay Bancorp entered into a six month
consulting agreement with John J. Hounslow, a director of Greater Bay Bancorp.
For his services under the agreement, which involved primarily business
development activities and oversight of the merger integration of Mt. Diablo
National Bank, the Company paid Mr. Hounslow a total of $99,000. In connection
with his appointment as a director of Greater Bay Bancorp, he was also granted
an option to purchase 18,000 shares of the Company's Common Stock at an exercise
price of $19.6875 per share, the fair market value of such stock on the date of
grant.

(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 SEC rules. Actual gains, if any, on stock option exercises
     are dependent on the future performance of Greater Bay Bancorp Common
     Stock, overall market conditions and the option holders' continued
     employment through the vesting period. The amounts reflected in this table
     may not necessarily be achieved. One share of stock purchased in 2000 at
     $37.125 would yield profits of $23.35 per share at 5% appreciation over ten
     years, or $59.17 per share at 10% appreciation over the same period.

Employment Contracts, Change in Control Arrangements and Termination of
Employment

     Employment Contracts. Effective January 1, 1999, Greater Bay Bancorp
entered into a five-year employment agreement with its President and Chief
Executive Officer, David L. Kalkbrenner. The agreement provides for, among other
things (a) a base salary of $360,000 per year, which the Board may adjust
annually at its discretion; (b) a discretionary annual bonus based upon the
Company's pre-tax net profits; (c) in the event that Mr. Kalkbrenner becomes
disabled so that he cannot perform his duties, payment to him of his base salary
for one year, reduced by any amounts received by him from state disability
insurance, worker's compensation or similar insurance; (d) five weeks annual
vacation; (e) a $500,000 life insurance policy; (f) an automobile allowance; (g)
supplemental retirement benefits (see "Supplemental Executive Retirement Plan"
below); and (h) reimbursement for ordinary and necessary expenses incurred by
Mr. Kalkbrenner in connection with his employment. On December 11, 2000, Greater
Bay Bancorp and Mr. Kalkbrenner amended the agreement to provide that he may
participate in the Company's group health and medical plans upon his retirement
or termination upon a change in control. Greater Bay Bancorp may terminate the
agreement with or without cause.

     Upon Mr. Kalkbrenner's involuntary termination of employment for any
reason, Mr. Kalkbrenner will be entitled to receive severance benefits equal to
36 months of salary at the rate in effect immediately preceding the termination
and the amount of any bonus due him. In the event of a termination of his
employment following a change in control of Greater Bay Bancorp, Mr. Kalkbrenner
will be entitled to receive severance pay equal to 2.99 times his average annual
compensation for the five years immediately preceding the change in control. If
any portions of this amount constitute "excess parachute payments" under the
Internal Revenue Code of 1986, Greater Bay Bancorp will increase the amount
payable to Mr. Kalkbrenner to account for any excise tax that may be imposed on
him.

     The benefits provided to Mr. Kalkbrenner under the agreement supersede any
benefits to which he may otherwise be entitled under Greater Bay Bancorp's
Termination and Layoff Pay Plan for Key Executives and Change in Control Pay
Plan for Key Executives (as described below) to the extent they exceed the
benefits otherwise payable under these plans.

     Change in Control Plans. Effective January 1, 1998, the Greater Bay Bancorp
Board of Directors adopted the Greater Bay Bancorp Change in Control Pay Plan
and the Greater Bay Bancorp Change in Control Pay Plan for Key Executives,
referred to as the "Change in Control Plans", to provide eligible employees and
key executives with severance benefits upon their termination of employment on
account of a change in control. The Change in Control Plans provide that a
change in control occurs when Greater Bay Bancorp is sold or otherwise
transferred in ownership to new ownership.

     The Change in Control Plans generally provide each participant with a base
benefit based on the participant's pay, full years of service with Greater Bay
Bancorp or a subsidiary, and his or her title or position at Greater Bay Bancorp
or the subsidiary as of the date he or she terminates employment, and an added
benefit based on the participant's pay and his or her full years of service as
of the date of his termination of employment. "Pay" for purposes of the Change
in Control Plans means the total annual compensation paid to an employee,
including base wages and average bonus paid to the employee in the three most
recent years.

     Under the Change in Control Plan for Key Executives, Mr. Kalkbrenner would
be entitled to receive a base benefit equal to 25 months of pay and an added
benefit of 2 weeks of pay for each full year of service for a maximum severance
of up to 3 years of pay; Mr. Smith would be entitled to receive a base benefit
equal to 20 months of pay and an added benefit of 2 weeks of pay for each full
year of service, for a maximum severance of up to 2 1/2 years of pay; and Mr.
Hood, Ms. Black and Mr. Johnson would each be entitled to receive a base benefit
equal to 18 months of pay and an added benefit of 2 weeks of pay for each full
year of service, for a maximum severance benefit of up to 2 years of pay.

     Termination and Layoff Plans. The Greater Bay Bancorp Board has also
adopted the Greater Bay Bancorp Termination and Layoff Pay Plan and the Greater
Bay Bancorp Termination and Layoff Pay Plan for Key Executives, referred to as
the "Termination Plans", effective January 1, 1998. These plans provide

                                       14


severance benefits to eligible employees and key executives upon the termination
of their employment because of circumstances which the Termination Plans define.

     The Termination Plans also provide each participant with a severance
benefit based on the participant's pay, full years of service with Greater Bay
Bancorp or a subsidiary, and his or her title or position in Greater Bay Bancorp
or the subsidiary as of the date of his or her involuntary termination of
employment or layoff. "Pay" for purposes of the Termination Plans means the
total annual compensation paid to an employee, including base wages and average
bonus paid to the employee in the three most recent years.

     Under the Termination and Layoff Plan for Key Executives, Mr. Kalkbrenner
would be entitled to receive a severance benefit equal to 25 months of pay; Mr.
Smith would be entitled to receive a severance benefit equal to 20 months of
pay; and Mr. Hood, Ms. Black and Mr. Johnson would each be entitled to receive a
severance benefit equal to 18 months of pay.

     Greater Bay Bancorp's Stock Option Plan. The Greater Bay Bancorp Board of
Directors adopted the Greater Bay Bancorp 1996 Stock Option Plan in 1996, as
amended, referred to as the "Option Plan". The Option Plan allows Greater Bay
Bancorp to offer selected employees, directors and consultants an opportunity to
purchase Greater Bay Bancorp Common Stock or to receive grants of restricted
stock. Through this plan, the Board hopes to motivate such individuals by giving
them an ownership interest in Greater Bay Bancorp's success.

     Options and restricted stock granted under the Option Plan contain a
provision that takes effect upon a "change in control" of Greater Bay Bancorp.
Prior to the happening of any such change in control, all options granted under
the Option Plan will become immediately exercisable and all restrictions on
restricted stock will immediately lapse.

     Supplemental Executive Retirement Plan. In December 1997, the Greater Bay
Bancorp Board of Directors approved the implementation of the Greater Bay
Bancorp Supplemental Executive Retirement Plan, referred to as the SERP, which
provides supplemental retirement benefits to a select group of management or
highly compensated employees of Greater Bay Bancorp and its subsidiaries who
have titles of senior vice president or above. Greater Bay Bancorp's management
designates those employees who are eligible to participate in the SERP.

     Benefits under the SERP include income generally payable commencing upon a
designated retirement date for the life of the participant and a death benefit
for the participant's designated beneficiaries. The retirement benefits are
derived from accruals to a benefit account during the participant's employment.
The benefit account accruals are determined annually. A portion of the accrual
is based upon annual earnings (or loss) and certain investment opportunity costs
related to life insurance contracts owned by Greater Bay Bancorp. The remainder
of the accrual expense is based on an actuarial measurement of the value of
post-retirement benefits earned during the current year.

     With respect to the persons named in the Summary Compensation Table,
retirement benefits are also provided from contributions to secular trusts that
were established in 1999. Greater Bay Bancorp's annual contributions to the
secular trusts are determined by calculating the amount that must be invested
each year during the employee's working life, in order to provide retirement
income equal to 50% of the after-tax total projected retirement benefits.
Greater Bay Bancorp reviews the level of the contributions periodically to
assure the trusts are adequately funded to provide the guaranteed benefits.
Greater Bay Bancorp has purchased life insurance policies on the participants in
order to finance the cost of these benefits.

     SERP benefits for the persons named in the Summary Compensation Table vest
at a rate of approximately 20% after 5 years of service and 20% each year
thereafter. Vesting accelerates to 100% upon a change in control of Greater Bay
Bancorp to the extent any portion of such benefits remains unvested at such
time. Upon a termination of employment for "cause", the participant forfeits all
benefits. The participant is entitled to all vested benefits in the case of a
termination without "cause"; however, if a

                                       15


participant voluntarily resigns prior to becoming 100% vested, his or her
benefits are reduced by amounts ranging from a total forfeiture to approximately
40% of benefits.

     As of December 31, 2000, Mr. Kalkbrenner was credited with 13 years of
services under the SERP; Ms. Black was credited with 10 years of service under
the SERP; Mr. Hood was credited with 10 years of service under the SERP; Mr.
Johnson was credited with 3 year of service under the SERP; and Mr. Smith was
credited with 11 years of service under the SERP.

     At retirement age of 65, Mr. Kalkbrenner will be entitled to receive a
projected benefit under the SERP that is equal to 29% of his 2000 total
compensation. At retirement age of 62, Ms. Black will be entitled to receive a
projected benefit of 38% of her 2000 total compensation; Mr. Hood will be
entitled to receive a projected benefit of 44% of his 2000 total compensation;
Mr. Johnson will be entitled to receive a projected benefit of 36% of his 2000
total compensation; and Mr. Smith will be entitled to receive a projected
benefit of 42% of his 2000 total compensation.

Executive Committee's Report on Executive Compensation

     Set forth below is a report of our Executive Committee addressing the
compensation policies for 2000 applicable to our executive officers.

     The Report of the Executive Committee of the Board of Directors shall not
be deemed incorporated by reference by any general statement incorporating by
reference this Proxy Statement into any filing under the Securities Act of 1933
or under the Securities Exchange Act of 1934, except to the extent that Greater
Bay Bancorp specifically incorporates the information contained in the report by
reference, and shall not otherwise be deemed filed under such acts.

The Report

     The Executive Committee of the Board of Directors acts as our Executive
Compensation Committee. The Executive Committee establishes our overall
compensation and employee benefits and approves specific compensation levels for
executive officers. It is a goal of the Executive Committee to implement
executive officer compensation programs that further our business objectives and
that attract, retain and motivate the best qualified executive officers.
Currently, the members of the Executive Committee are John M. Gatto, Duncan L.
Matteson, David L. Kalkbrenner, Rex D. Lindsay, Donald H. Seiler and Warren
Thoits. Each member of the Executive Committee is a non-employee director,
except for Mr. Kalkbrenner.

     Compensation Policies. Greater Bay Bancorp's executive compensation
policies and specific executive compensation programs are adopted and
administered in accordance with the principal goal of maximizing return on
shareholders' equity. The Executive Committee believes that this performance
goal, and the long-term interests of our shareholders generally, are best
achieved by attracting and retaining management of high quality, and that such
management will require commensurate compensation. The Executive Committee
believes that our executive officer compensation policies are consistent with
this policy.

     In addition, the Executive Committee believes that while our compensation
programs should reflect the philosophy that executive compensation levels be
linked to the Company's performance, such compensation programs should also be
competitive and consistent with those provided to others holding positions of
similar responsibility in the banking and financial services industry. Our
compensation plans are designed to assist the Company in attracting and
retaining qualified employees critical to our long-term success, while enhancing
employees' incentives to perform to their fullest abilities to increase
profitability and maximize shareholder value.

     Annual compensation levels for executive officers are determined by the
Executive Committee based primarily on its review and analysis of the following
factors:

     .    the responsibilities of the position,

     .    the performance of the individual and his or her general experience
          and qualifications,

                                       16


     .    the overall financial performance (including return on equity, levels
          of general and administrative expense and budget variances) of Greater
          Bay Bancorp for the previous year and the contributions to such
          performance measures by the individual or his or her department,

     .    the officers' total compensation during the previous year,

     .    compensation levels paid by comparable companies in similar
          industries,

     .    the officer's length of service with Greater Bay Bancorp, and

     .    the officer's effectiveness in dealing with external and internal
          audiences.

     The Executive Committee believes that the base compensation of the
executive officers is competitive with companies of similar size and with
comparable operating results in similar industries.

     In 2000, the Company awarded special compensation to all employees,
including the executive officers, as the result of income earned on the exercise
of warrants granted by Greater Bay Bancorp's borrowers and in recognition of our
employees' extraordinary efforts in completing five mergers during the year as
well as our outstanding financial results for 2000. The Executive Committee
recommended these awards to reward our valued employees and as additional
incentive to retain them.

     Long Term Compensation Programs. While the Executive Committee establishes
salary and bonus levels based on the above described criteria, the Executive
Committee also believes that encouraging equity ownership by executive officers
further aligns the interests of the officers with the performance objectives of
our shareholders and enhances our ability to attract and retain highly qualified
personnel on a basis competitive with industry practices. Stock options granted
by the Company pursuant to the 1996 Stock Option Plan help achieve this
objective, and provide additional compensation to the officers to the extent
that the price of the Common Stock increases over fair market value on the date
of grant. Stock options have been granted to each of the executive officers and
to other officers or key employees. Through the 1996 Stock Option Plan, there
will be an additional direct relationship between the Company's performance and
benefits to plan participants.

     In addition, through Greater Bay Bancorp's Employee Stock Purchase Plan,
eligible employees who are scheduled to work at least 20 hours a week may
acquire an interest in our growth and productivity. Under this plan,
participants may purchase shares of Greater Bay Bancorp Common Stock through
payroll deductions. The purchase price per share generally equals 85% of the
lesser of the fair market value of a share on the first or last day of the
offering period. Offering periods are for three months, commencing the first day
of each calendar quarter.

     Certain key employees participate in the Company's Supplemental Executive
Retirement Plan. This plan provides supplemental retirement benefits to a select
group of management or highly compensated employees who have titles of senior
vice president or higher. Upon vesting, participants in the plan receive
lifetime retirement income benefits and death benefits.

     Eligible employees are also able to participate in Greater Bay Bancorp's
401(k) Plan. The 401(k) Plan permits participants to make 401(k) contributions
on a pretax basis. All employees who are at least 18 years of age are eligible
to participate in the 401(k) Plan. Participants can contribute up to 15% of
their pretax compensation to the 401(k) Plan annually, subject to certain legal
limitations. The 401(k) Plan also provides that the Company will make a matching
contribution on behalf of each eligible participant equal to 62.5% of the 401(k)
contributions made by such participants, up to 8% of their individual
compensation.

     Finally, our Board of Directors adopted the Greater Bay Bancorp 1997
Elective Deferred Compensation Plan at its December 1997 meeting. The Deferred
Compensation Plan is an unfunded Plan that provides deferred compensation
benefits to directors and a select group of management and highly compensated
employees who contribute materially to the continued growth, development and
future business success of the Company.

     Through these various compensation programs, the Executive Committee
believes that Greater Bay Bancorp furthers its objectives of attracting,
retaining and motivating the best qualified executive officers and employees,
and ultimately will serve to increase our profitability and maximize shareholder
value.

     Compensation of Chief Executive Officer. The base salary of our Chief
Executive Officer was determined primarily by the terms of his employment
agreement dated January 1, 1999 (see "Employment

                                       17


Contracts, Change in Control Arrangements and Termination of Employment"). The
agreement provides for a base salary, subject to annual adjustments by the Board
of Directors, and for a discretionary annual bonus based upon the pre-tax net
profits of the Company. In addition, the Chief Executive Officer's compensation
for 2000 was based in part on his progress in achieving certain additional
criteria. These criteria included completing five merger and acquisition
transactions, results in meeting Greater Bay Bancorp's strategic business plan,
total return to shareholders and leadership abilities. Based on the foregoing,
and a review of compensation paid to chief executive officers in the Company's
peer group (institutions with assets of $1-5 billion), in 2000, Mr. Kalkbrenner
received a base salary of $369,864, an annual incentive bonus of $450,000, a
special merger award of $175,000, a special award related to warrant income of
$150,000, 35,000 stock options and 6,000 shares of restricted stock. He also
received a 401(k) Plan matching contribution of $6,250. Mr. Kalkbrenner did not
participate in the Executive Committee's deliberations concerning his
compensation.

Respectfully submitted by the members of the Executive Committee:

Dated:  April 13, 2001                  Duncan L. Matteson, Chairman
                                        John M. Gatto

                DISCUSSION OF PROPOSALS RECOMMENDED BY THE BOARD

Proposal 1:  Elect Five Directors

     The Board has nominated five persons for election as Class I Directors at
the Annual Meeting. If you elect them, they will hold office until the election
of their successors at the Annual Meeting in 2004, or until they resign.

     We know of no reason why any nominee may be unable to serve as a director.
If any nominee is unable to serve, your proxy may vote for another nominee
proposed by the Board. If for any reason these nominees prove unable or
unwilling to stand for election, the Board will nominate alternates. The Board
has no reason to believe that its nominees would prove unable to serve if
elected.

     The following table sets forth the names and five-year biographies of the
five persons nominated by the Board to serve as Class I Directors. The table
also sets forth the names and five-year biographies of our Class II Directors
whose terms expire in 2002 and Class III Directors whose terms expire in 2003.

     The Board recommends that you vote "FOR" the election of all five Class I
Nominees for director.

Proposal 2:  Approve Amendment to Bylaws

     The Board of Directors has adopted, subject to shareholder approval, an
amendment to Section 1(a) of Article IVof the Company's Bylaws to increase the
range of authorized directors from 9 to 17, to a range of 11 to 21. The full
text of this proposed amendment to the Bylaws is set forth below:

     Section 1. Number of Directors. (a) The authorized number of
                -------------------
     directors shall be no less than eleven (11) nor more than twenty-
     one (21). The exact number of directors shall be fixed and may be
     changed from time to time by a resolution adopted by the Board of
     Directors.

     Increasing the maximum range of directors as proposed would provide the
Board with the flexibility to add to the Board qualified persons whose service
on the Board would benefit the Company without having to call a special meeting
of shareholders or wait until the next scheduled annual meeting to amend the

                                       22


Bylaws. In accordance with California law, which provide that the maximum number
of directors may not exceed the minimum by more than two times the minimum minus
one, we are also proposing to increase the minimum from 9 to 11.

The Board of Directors recommends that you vote "FOR" approval of this amendment
to the Bylaws.

Proposal 3:  Ratify Selection of Independent Public Accountants for 2001

     The Board of Directors has appointed PricewaterhouseCoopers LLP as our
independent public accountants for the year ending December 31, 2001, and
shareholders are being asked to ratify the appointment. The appointment was
recommended by the Audit Committee. PricewaterhouseCoopers LLP, our accountants
for the year ended December 31, 2000, performed audit services for 2000 which
included the examination of the consolidated financial statements and services
related to filings with the SEC. All professional services rendered by
PricewaterhouseCoopers LLP during 2000 were furnished at customary rates and
terms. Representatives of PricewaterhouseCoopers LLP will be present at the
Annual Meeting and will be available to respond to appropriate questions from
shareholders.

     The following table sets forth the aggregate fees the Company incurred for
audit and non-audit services provided by PricewaterhouseCoopers LLP, who acted
as independent accountants for the year ended December 31, 2000. The Audit
Committee considered whether the provision of non-audit services is compatible
with maintaining the independence of PricewaterhouseCoopers LLP.
